| 122 | Rolamite sensor | US419013 | 1989-10-10 | US4985604A | 1991-01-15 | Yosufi M. Tyebkhan |
| A rolamite sensor includes a formed sheet metal base attached to a metal chassis. One surface of the sheet metal base acts as a guide surface for a roller. A thin metal foil band is wrapped around the roller and has its ends welded to the base underneath the base. The roller is biased into a first position and is rollable on the guide surface from its first position under an applied force to cause the band to engage a firing contact. A single pin connected to the firing contact extends through the chassis and is electrically insulated from the chassis. The pin and chassis are connected to opposite electric potentials in the vehicle. When the band engages the firing contact, an electrical circuit is completed through the pin, the firing contact, the band, the base, and the chassis to activate a vehicle safety apparatus. The sheet metal base includes a calibration tab which sets the first position of the roller along the guide surface. The tab may be physically bent to select the distance through which the roller needs to travel to complete the electrical circuit. | ||||||

| 124 | Thermostat and method of testing thereof | US40996 | 1979-05-21 | US4258325A | 1981-03-24 | Steven R. Richardson |
| A thermostat is disclosed and claimed in which a totally enclosed switch is operated by a bimetal snap disc. The housing is provided with a small opening through which a testing probe may be inserted to test the gaging of the assembled device. Such opening is closed by a thin adhesively applied closure element, the application of which cannot alter the operation of the thermostat. A method of testing is also disclosed in which the thermostat is essentially fully assembled and then thermally cycled while a probe extends through a small opening to monitor the position of the movable element of the switch to determine the position within the snap range of the disc at which the switch closes. After the testing, the opening through which the testing probe extends is closed to complete the assembly of the device. | ||||||
| 125 | Acceleration sensitive switch | US700501 | 1976-06-28 | US4093836A | 1978-06-06 | Robert J. Ewy; Robert P. Moore |
| A switch structure detects acceleration in a preselected direction such as, for example, along the pitch axis of an aircraft. The switch has a spring supported mass urged toward a stable centered position within the switch housing. Acceleration displaces the mass such that it trips a spring wire switch mechanism for controlling such avionic devices as the autopilot system of the aircraft. A pair of solenoid coils are wound around the spring mass system on opposite sides of the centered position of the mass. The switch may be preflight tested by successively energizing the solenoid coils to attract the mass toward the centers of the solenoid fields, thereby artifically displacing the mass against the spring wire switches. | ||||||
| 126 | Disc thermostat test system and method | US469721 | 1974-05-14 | US3947758A | 1976-03-30 | Walter T. Sutton |
| The disclosure relates to a system and method whereby bimetallic discs as well as a completed thermostat can be dynamically tested non-destructively. The bimetallic disc can be tested by utilizing its magnetic properties, the magnetic properties of the disc being sensed by a magnetic transducer under operating conditions to provide a velocity curve of disc movement. The thermostat is tested in the same manner as the disc with simultaneous monitoring of the electrical switch controlled by the disc to insure operation thereof at the ideal point on the disc velocity curve. | ||||||

| PURPOSE: To provide an acceleration sensor which is highly versatile as an impact sensor to start a vehicle safety restraint system, compact in size, firm in structure, and capable of being manufactured at a relatively low cost, and the vehicle safety restraint system in which the acceleration sensor is employed. CONSTITUTION: Permanent magnets 24, 28 are resiliently urged toward a first position adjacent to one end of a cavity 22, and the acceleration applied to the permanent magnets urge the permanent magnets to a second position against the force to be resiliently applied to the permanent magnets. An electric switch contact piece is extended inward of the cavity and engaged with a surface of the magnets. The surface of the magnets comprises a first surface portion 42 of a conductive structure and a second non-conductive surface portion 44 adjacent to each end. The conductive and non-conductive portions are separate from each other, and a switch contact is engaged with one of these surface portions at the first position, and engaged with the other at the second position.

| PURPOSE:To stabilize contact resistance between an electrode and a magnet assembly. CONSTITUTION:When a large external force occurring upon the collision or the like of vehicles is applied along an arrow A direction, a magnet assembly 14 advances to the forward end of a cylindrical body 12, thereby causing an electrode 60 to come in contact with another electrode 62. Then, the conductive material casing 18 of the magnet assembly 14 causes shortcircuit between the electrodes 60 and 62, and electric current flows across the electrodes 60 and 62. As a result, the occurrence of a change in acceleration over the predetermined threshold is detected and a vehicle collision is detected. The peripheral section 61 of the electrodes 60 and 62 is constituted in such a way as bent in a direction opposite to the magnet assembly 14. As the peripheral section 61 of the electrodes 60 and 62 where the magnet assembly 14 contacts, is bent in a direction opposite to the assembly 14, contact resistance between the electrodes 60 and 62, and the magnet assembly 14 becomes stable. The contact of the electrodes 60 and 62 with the assembly 14 can be thus detected with high accuracy, thereby enhancing remarkably the detecting accuracy of acceleration. | ||||||

| PURPOSE: To prevent production of a fluctuation in a brake (damping) force exerted on a magnetized inertia body owing to a change in a peripheral temperature by method wherein an acceleration sensor to detect a speed change during collision of a vehicle has the magnetized inertia body located at the interior thereof and comprises mainly a cylinder body to the end surface of which a pair of electrodes are located, and a pair of the electrodes are energized as a result of a conductor, located to the end surface of the magnetized inertia body, making contact with the electrodes. CONSTITUTION: A second coil 37 different from a coil 34 for test of a magnetized inertia body 14 and capable of magnetically energizing the magnetized inertia body or absorbing energy thereof is provided. A change in a brake (damping) force exerted on the magnetized inertia body along with movement of the magnetized inertia body is compensated by means of a second coil 37.

| PURPOSE: To enable disconnection of a lead wire between an electrode and a collision detection circuit main body to be detected positively by providing an electrical resistor between electrodes which a magnetization inertial body contacts with and by forming both electrodes and the electrical resistor in one piece by insert molding of a synthetic resin. CONSTITUTION: Electrodes 40 and 42 are formed as one part of conductive pieces 46 and 48 which consist of a pressed sheet material which is made of a thin copper plate. An electrical resistor 54 is erected between conduction pieces 46 and 48 and a main part of the conduction pieces 46 and 48 is buried within a conductor holder. This configuration allows the electrical resistor 54 to be positioned closest to the electrodes 40 and 42 so that disconnection closest to the electrode can be positively detected. Also, since a large part of the electrodes 40 and 42 and the electrical resistor 54 can be buried into a synthetic resin, the electrode and electrical resistor can also be protected.

| PURPOSE: To decrease the change in acceleration threshold value with the fluctuation of temperature by limiting the resistance temperature coefficient of a tube body comprising conductive material wherein a magnetized inertial body is inserted. CONSTITUTION: An acceleration sensor is provided with a tube body 12, a magnetized inertial body 14, a conductor 18 which is provided at the edge of one-end side of the magnetized inertial body 14 in the longitudinal direction, a pair of electrodes 40 and 42 and an attracting body 30 comprising a magnetic material which is magnetically attracted with the magnetized inertial body 14 to each other. In the acceleration sensor, the tube body 12 is made of a metal whose resistance temperature coefficient is 3 × 10 -3 or less. Even if the ambient temperature is changed, the change in braking force which is applied to the magnetized inertial body with the movement of the magnetized inertial body 14 becomes small.
