188 Containment of an aerosolable liquid jet US950354 1992-09-24 US5286456A 1994-02-15 Klaus W. Schatz
System for increasing rainout from a liquid jet of an aerosolable corrosive and toxic substance, e.g. hydrogen fluoride, hydrofluoric acid, ammonia or chlorine, exiting from a pressurized source such as a vessel, conduit, pump. The system includes an impact plate spaced from the pressurized source for deflecting the liquid jet to dissipate forward velocity and energy of the liquid jet. The impact plate is positioned a distance from the pressurized source to impact the liquid jet before the liquid is capable of expanding to form a substantial aerosol of vaporized substance. A mesh pad abuts the impact plate and faces the pressurized source for initially reducing the velocity and energy of the liquid jet, and for preventing back and radial splash of the liquid jet deflecting off the impact plate to coalesce droplets of the substance and thereby produce a collectable run-off.

190 Reduction of the emission of hydrocarbons in pressure-reduction processes in high pressure polymerization reactors US127988 1987-12-03 US4804725A 1989-02-14 Friedrich Kanne; Franz G. Mietzner; Klaus Pfleger; Siegfried Kursawe; Klaus Boettcher; Gerhard Arnold
The pressure in a continuous high pressure polymerization system, in which ethylene, with or without comonomers, is polymerized under high pressures and temperatures and the unconverted amounts of gas are recycled through the high pressure recycle gas system into the polymerization system, is rapidly reduced to below the particular reaction pressure when predetermined limiting pressure and/or temperature values are exceeded or when other faults occur by opening one or more pressure-relief apparatuses mounted on the high pressure polymerization system and transferring the hot let-down reaction mixture from the polymerization system via one or more let-down lines through one or more separator systems into the atmosphere, by a process in which the high pressure polymerization system is divided into a plurality of isolated sections at the same time as the let-down process is triggered and only the section in which the let-down process is triggered is let down to the atmosphere. Preferably, the sections in which the let-down process is not triggered can be let down into the high pressure recycle gas system, if necessary through a product separator, in synchronization with triggering of the let-down to the atmosphere.

192 Chemical reactor US001303 1987-01-08 US4741881A 1988-05-03 Hans K. Fauske
A chemical reactor vessel is provided with a plurality of tubes filled with a heat exchange fluid. The tubes are disposed in a heat exchange relationship with the reactor contents and are coupled via pressure sensitive rupture discs and a header to a reservoir. Upon overheating of the reactor contents, excess heat is absorbed by the heat exchange fluid which boils off at a predetermined vaporization temperature and vapor pressure to rupture the discs and thereby establish fluid communication between the tubes and a heat exchange fluid contained in the reservoir, and thereby maintaining the reactor contents at a preselected safe temperature.
193 Numerical control device US613472 1984-05-23 US4633409A 1986-12-30 Katsuhide Sekikawa
A numerical control device stores dimensional details of a workpiece, a chuck, and a tailstock as coordinate data items in a memory, computes the positions and shapes of the workpiece, the chuck, and the tailstock based on the coordinate data items, and displays the workpiece, the chuck, and the tailstock as graphic patterns on a display unit based on the computed results. The computation is simplified by using coordinates of a relative coordinate system as the coordinate data items for graphic display.
194 Heat cooking apparatus with temperature operating system US597752 1984-04-06 US4551601A 1985-11-05 Nobuichi Nishimura
A heat cooking apparatus with a temperature operating system, wherein a microcomputer detects an abnormality of a temperature sensor and de-energizes the cooking apparatus to stop cooking while also producing a sensor fault pulse signal. Upon counting of a predetermined number of sensor fault pulse signals in a counter, the microcomputer generates a sensor defect signal to alert the user of the defective temperature sensor. Spurious fault conditions are ignored by resetting the counter upon proper operation of the sensor before reaching the predetermined number of sensor fault pulse signals.
195 Automatic shut-off and alarm for stove heating unit US653763 1976-01-30 US4070670A 1978-01-24 Ho Chi Chen
The invention relates to a safety control shut-off device for the heating element of a cooking stove. In one embodiment of this safety device, a burner plate of the stove is provided with several declining U-shaped grooves for collecting any spillage or overflow of water from the cooking operations. Water drops collected in the declining grooves are led through a discharge outlet, at the lowest portion of the grooves, and into a water drop detector located beneath the outlet, to complete an electrical circuit, which in turn will actuate and sound an alarm and will also actuate means for disconnecting the fuel source of the plate burner.

A pilot valve for sensing a first fluid pressure such as a well flow line and controlling a second fluid pressure of a system such as a well safety valve in response to a change in the first pressure. The pilot valve includes a bourdon tube coupled with a bleed valve which is activated in response to predetermined high and low values of the first pressure sensed by the bourdon tube. The bleed valve is connectable to the first pressure, such as a control pressure of a safety valve, for exhausting the control pressure for closing the safety valve in response to either the high or low predetermined pressure sensed by the bourdon tube. The bourdon tube is also connected with indicator means which show whether the pilot valve system operated in response to a high or a low sensed pressure. The pilot valve additionally includes means for indicating which of several such pilot valves was activated first where a plurality of such valves are interconnected in a fluid system.
