A pressure pulse generator containing a pyrotechnic driving charge is arranged in the cutting device for generating a pressure pulse to drive the cutting tool. In the guiding housing there is arranged, between the pressure pulse generator and the cutting tool, an impact capsule that can be accelerated by the pressure pulse of the triggered pressure pulse generator toward an inner thrust base of the cutting tool on the end of the cutting tool opposite to the cutting chisel. The cutting tool has its cutting chisel abutting the cut point before the impact capsule strikes the thrust base. | ||||||
| 84 | Pyrotechnic microactuators for microsystems | US10471632 | 2002-04-23 | US06994030B2 | 2006-02-07 | Christian Perut; Denis Roller |
| The technical field of the invention is that of microactuators designed for mechanical, chemical, electrical or thermal functions in microsystems, for microelectronic applications such as chips, or biomedical applications such as cards incorporating microfluidics. The invention concerns a microactuator comprising a chamber machined in a solid support and containing a pyrotechnic charge. Said microactuator is essentially characterised in that the chamber is partly delimited by a deformable membrane, such that the gases emitted by combustion of the pyrotechnic charge enable to increase the volume of said chamber by deforming said membrane while maintaining intact the solid walls of the chamber. | ||||||

| This invention relates to a pyromechanical disconnecting apparatus, in particular for battery shutoff in a motor vehicle, having a housing (4) in which there is arranged an electrically conductive conductor bus (2), which is fashioned so as to be severable at a predetermined cut position (1) by a cutting chisel (6) driven by a pyrotechnic propellant charge, the conductor bus (2) is clamped in on its side facing away from the cutting chisel (6) by a locking bolt (5) inserted into the housing (4), and a receiving space (15) is arranged in the locking bolt (5) in the region of the predetermined cut position (1), into which receiving space the cutting chisel (6) bends the region of the conductor bus (2) severed by it, and the locking bolt (5) forms an external surface of the housing (4). In order to diminish cracking of the locking bolt and housing and for purposes of inspection to determine whether the disconnecting apparatus has tripped, it is proposed that a recess (13) be arranged in the locking bolt (5), which recess transpicuously connects the receiving space (15) with the atmosphere. | ||||||

| 92 | Circuit breaker | US09438958 | 1999-11-12 | US06275136B1 | 2001-08-14 | Noboru Yamaguchi |
| The circuit breaker disclosed in the invention comprises a first connection terminal, a second connection terminal, a rotatable conducting part disposed between the first connection terminal and second connection terminal, a heat generating part, an igniting part igniting depending on a cut-off signal, an elastic member capable of producing a rotating force, and a holding part for holding the conducting part while resisting the rotating force of the elastic member. Herein, when the holding part releases holding of the conducting part as the igniting part ignites depending on the cut-off signal and the heat generating part generates heat, the conducing part is rotated by the rotating force of the elastic member, and the conductive state between the first connection terminal and second connection terminal is cut off. | ||||||
| 93 | Current interrupting apparatus | US09326606 | 1999-06-07 | US06232568B1 | 2001-05-15 | Tetsuya Hasegawa; Noboru Yamaguchi |

The cutting of the connecting member by the cutting device interrupts the supply of electric current from the battery to the load by way of the battery terminal and the load conductor wire. | ||||||
| 94 | Inductive store opening switch | US399017 | 1982-07-16 | US4571468A | 1986-02-18 | William F. Weldon |
| The inductive store opening switch includes a cartridge casing comprising a length of metal tubing, for disposition between a pair of electrical buss bar conductors and in contact with both so as to establish a path for electrical current therethrough. The tubular casing, having inner and outer surfaces, is scored on its outer surface to establish a rupturing point. The scoring on the outer surface may constitute many different geometric forms. A solid body of inert material is insertable within the casing and disposed adjacent the rupturing point of the casing. A propellant cartridge carrying a combustible material, such as gun powder, is disposed within the casing opposite the inserted body so as to define a cavity volume within the casing proximate the rupturing point of the casing. The cartridge further includes structure for igniting the material. The oxidation-gas products produced by ignition of the material in the propellant cartridge expand into the volume defined within the casing and cause rupturing of the casing along the scoring, thereby breaking the electrical current path established by the casing. Reinforcement members extending circumferentially of the casing on opposite sides of the scoring, may be used to control the extent of rupturing of the casing and control the gap width between casing halves. Alternatively, the casing may be ruptured by introduction of a pressurized fluid by the dumping of fluid from a high pressure accumulator into the cavity volume using a fast-acting valve. | ||||||
| 95 | Explosively-actuated, multi-gap high voltage switch | US539396 | 1983-10-06 | US4490707A | 1984-12-25 | Raymond P. O'Leary |
| A high-speed switch usable at high voltage includes a pair of contacts movable apart along a fixed line. When the contacts are normally interconnected, at least one of them contributes to the definition of an enclosed chamber. Pressurization of the chamber by the ignition of a power cartridge therein rapidly drives the contacts apart, forming a first gap between them. The first gap is electrically insulated and is shielded from the ignition products of the cartridge. Any arc forming in the first gap is constricted and subjected to arc-extinguishing gas. When the contacts are interconnected, a first one of them is electrically connected to a terminal. After the contacts move apart, a second gap forms between the first contact and the terminal. The second gap is electrically insulated and is shielded from the ignition products of the cartridge. A fuse may be connected in shunt with the contacts and the insulated gaps. Preferably, the shunt connection is made after the first gap is formed, but before the second gap is formed. This permits the first gap to effect commutation of current from the switch to the fuse and the second gap to be formed after the communtation. The second gap thus experiences no or only limited arcing and remains essentially uncontaminated so that recommutation of current from the fuse to the switch is prevented. | ||||||
| 96 | Fast acting explosive circuit interrupter | US880700 | 1978-02-23 | US4224487A | 1980-09-23 | Bent P. Simonsen |
| A high speed, high impedance explosive circuit interrupter is disclosed which attenuates the magnitude and duration of fault currents accompanying circuit faults in electrical circuits protected by conventional circuit isolation apparatus. By so doing, the disclosed elements improve the operating speed and effectiveness of the breaking system and the protection of fault sensitive equipment. | ||||||
| 97 | Circuit breaking device | US3745276D | 1972-03-01 | US3745276A | 1973-07-10 | MCPHERSON J |
| A device for breaking a circuit which comprises an anvil and a cutter cooperating with the anvil and a printed circuit board between the anvil and cutter, the circuit to be broken comprising conductors in each of the cutter and anvil and a connection between those conductors through the printed circuit board. Actuation of the device, for example by an explosive cartridge, causes the cutter to move toward the anvil and break a piece from the printed circuit board and at the same time to break the connection between the conductors of the anvil and cutter.

| 99 | Current circuit breaker | US3700970D | 1971-02-18 | US3700970A | 1972-10-24 | MIYOSHI NORIOMI |
| The electrical energy for detonating an explosive in a circuitopening mechanism of a current circuit breaker to cut a circuit path is derived through a current transformer from the circuit path to which the circuit breaker itself is connected. The circuit-opening mechanism can thereby be exploded to cut the circuit path without the necessity of supplying electrical energy from any outside agency other than the circuit path. Furthermore, rapid extinguishing of the arc generated by the circuit path cutting is afforded by an insulative medium blown against the arc by the explosion, and the path parts thus cut apart are prevented by a unique construction from recontacting to remake the circuit.
