Title: Unanswered caller telephone number storage system - has command code transmitter and memory register at extension
IPC: H04M1/57
Filed: 1974-05-15
Abstract: When a telephone extension in a large establishment is not answered due to absence of personnel, the person calling can send a code number which is stored at the receiving end. When the absent person returns an observation screen can be operated to display the memory contents. In a digital time sharing multiplex telephone system the extension comprises a receiving section and transmitting section. A microphone is connected through an analogue to digital converter to a register in order to transmit the signals through a signal generation circuit. Received digital signals enter a register after synchronisation and address detection and are decoded for the earpiece. A register receives the number of persons who called and a display enables these to be displayed when a button on the keyboard is operated.

Title: Membrane type gas compressor - has swashplate adjustable to vary output, with compensating balance disc simultaneously adjusted
IPC: F01B3/10
Filed: 1975-06-24
Abstract: The compressor has a shaft which carries a hub supporting an inclined swashplate on ball bearings. Struts run in a groove in teh swashplate and the other ends of the struts support discs causing membranes to deflect in the working chambers. Beneath the hub is a disc inclined at an opposite angle to teh swashplate so that it balances the otherwise out of balance forces on the swashplate. A sleeve is moved up or down the shaft by a lever and connected to the balancing disc and the swashplate by linkage bars to vary the inclination of the swashplate and disc while the machine is in motion. This varies the output while maintaining the balance of the swashplate and disc.

Title: Smectic:A phase liq. crystal recording and memory system - modifies molecular arrangement and optical properties by electric writing field
Inventor: GOSCIANSKI MICHEL
IPC: G02F1/133
Filed: 1975-07-29
Abstract: Data are represented by modifications of the optical properties of a liq. crystal system. An electrical writing field is used to modify the molecular arrangement in the liq crystal and thus its optical properties. The orientation of the molecules in the initial smectic-A state depends upon the sign of the dielectric anisotropy. The liq. crystal system is illuminated by a readout beam. The electric field then induces faults in the liq. crystal s.t. the beam becomes diffused. The final orientation of the molecules is homeotropic when the electric field exceeds a threshold level. The liq. crystal system may be placed between two crossed polarizers orientated at 45 deg. to the alingment direction of the molecules in the liq. crystal.

Title: Multi-purpose control valve for pneumatic suspension - has pressure control and valve for operating third axle suspension
IPC: B62D61/12
Filed: 1975-08-13
Abstract: The vehicle is fitted with a special trailing axle next to the driven axle, to take some of the load. This axle can be lifted off the ground, by extending the pneumatic suspension so that the tyre wear can be reduced for an empty vehicle and the vehicle is able to corner more easily. The suspension of the trailing axle is controlled by a pneumatic valve, operated by the driver. For a simpler layout the valve is mounted in the same housing as a pressure control valve, which automatically lowers the trailing axle if the driven axle is loaded more than a set amount. The housing also incorporates a pressure holding valve, to keep the axle extended and a non return valve.
