Title: Load responsive vehicle brake pressure regulator - includes deceleration responsive ball to control differential plunger movement
IPC: B60T8/26
Filed: 1975-01-31
Abstract: The device has a differential plunger axially movable in a stepped bore formed in a housing for modulating a first fluid pressure supplied to it when the pressure exceeds a critical magnitude. One end face of the plunger is exposed to a second fluid pressure and the other end face is isolated from the first and second fluid pressures, but receives such a compression force from a spring that the critical magnitude is raised if the second fluid pressure is not supplied to the former end of the plunger. A ball which is disposed in the housing moves and closes a valve when the device is subjected to a deceleration larger than a predetermined magnitude.
Patent FR-2264345-A1 (FR)
Title: Sound generating frequency converter - has groups of dividers for rising or falling flanks of input pulses
IPC: G10H5/00
Filed: 1975-03-14
Abstract: The dividers input is connected to the first input of a first series of gate circuits. A suppressor circuit comprises one input receiving a series of pulses, an output leading via an inverter circuit to the divider group and a second input connected to the first gate circuit. A pulse received at the second input causes suppression of a pulse at the first input. Each divider provides a frequency 2-x times that of the series of pulses at the input of the divider series, where x is the ordinal number of the divider. The divider groups are formed by the adjacent dividers where 2-x in the binary counting system is an even number (0 or 1) and the binary number is formed by the frequency which must be subtracted from the series of pulses, in order to obtain the frequency of the desired range at the input of the divider series, the latter frequency being standardised at 1.

Title: Thyristor based direct current electronically controlled switch - uses additional thyristors and inductances to switch main thyristors off
IPC: H02M7/515
Filed: 1975-10-01
Abstract: The thyristor switch must typically deal with an inductive and resistive load (5). The switch is closed by an electronic timing, or firing circuit (14) driving the base of the main thyristor (3). To open the switch a further thyristor (8) is connected across the switching thyristor, and a number of other components including a specially constructed inductance (18) are used. This second thyristor is again driven by the electronic timing circuit, and depending on the various conditions, the first thyristor is switched off by means of an inductively induced reverse voltage produced for a time dependent on these conditions.

Title: Electric welding jaw closure controlled by electrostatic facial crest - as a wear-free means to limit weld thickness
Inventor: GARDE BERNARD PIERRE GEORGE
IPC: B29C65/04
Filed: 1976-05-21
Abstract: Electrically heated jaws for compressing and welding superimposed layers of thermoplastic material, where one jaw face features a point or rib to act as focus for electrostatic effects.

Title: Water separator for air supply to pneumatic tool - has cyclonic action discharging water laden air to atmosphere by centrifuging
IPC: B01D53/26
Filed: 1976-09-17
Abstract: The separator is connected in the supply hose of a pneumatic tool. It has a body with a lower cylindrical section (7) forming the inlet and an upper cylindrical section (16) forming the outlet. The two parts screw together. Guide vanes (20) at the inlet give the air a spiral motion which centrifuges water particles to the outside. The upper part (16) has a central sleeve (33) projecting into the lower part and the water ladden air centrifuged to the outside finds it way into the annular gap (37) between this sleeve and the casing. The air and water is discharged to atmosphere through an opening (24) in the side of the casing while the water free air continues up the inside of the central sleeve (33).

Title: Motor vehicle air conditioning system - has heater with refrigerant passed through ejector and nozzle to operate evaporator by vacuum
IPC: F25B1/08
Filed: 1976-09-17
Abstract: The motor vehicle air conditioning system has a heater (1), to which hot water (2) is delivered, typically from the engine cooling system. the heater contains refrigerating liquid, to which the water transmits its heat, causing it to boil at a high pressure, producing vapour. The vapour is transported in succession to an ejector (4) and a nozzle (5, 12), generating a vacuum in a pipe leading from an evaporator in the chamber to be cooled. The vacuum causes the coolant at low temp. in the evaporator to boil, extracting heat from the chamber, and a condenser receives the mixture of the two gases, liquifying them so as to yield to atmosphere the enthalpy extracted from the chamber.
