IPC: G01R23/00
Filed: 1970-06-11
Abstract: 1,256,831. Frequency analyser. INTERNATIONAL BUSINESS MACHINES CORP. 12 June, 1970 [27 June, 1969], No. 28511/70. Heading G4H. A frequency analyser converts an incoming signal to digital form representative of the amplitude of the signal at successive time intervals, stores the signals, reads the same signal out successively at repeatedly faster frequencies, converts it back into an analogue form and passes it through a band-pass filter so that the frequency distribution of the input is effectively swept through the frequency interval of the band-pass filter. An incoming signal is converted into digital form by A to D converter 11; it is then read into buffer 14 which may comprise a series of shift registers by means of clock pulses W generated by clock 15. When the input signal has been sampled for a preset period the write gate 12 switches off and read gate 17 opens. The contents of the buffer 14 is then read through repeatedly at successively faster frequencies F 0  to K n .F 0 , the result being fed back into the buffer via gates 17 and also being converted to an analogue signal by means of digital to analogue converter 20. The output is then fed through a band-pass filter and detector unit 21 to determine the frequency distribution of the input. In a modification the apparatus may be used for a multiplexing system, Fig. 3 (not shown), a single clock (15) drives a series of memory circuits of the type just described through a multiplexing switch. The outputs are then fed through a multiplexing switch to a digital to analogue converter and a band-pass filter (21).

Title: Gypsum for the building trade - being very finely ground and partially dehydrated
IPC: C01F11/46
Filed: 1971-03-30
Abstract: Plastering and structural gypsum is prepd. by grinding of the gypsum to a terminal extreme particle fineness, when it is converted into a lower hydrated state in a continuously operated closed heat exchanger, following which in the same heat exchanger terminal particle fine ground raw gypsum is added to it and mixed with it causing spontaneous direct heat exchange between the two. The heating is carried out in a closed horizontal revolving shaft kiln. The process removed the need for additional grinding and further heat treatment after mixing.

Title: Automobile radar brake controller - has sensor signal fed to electronic recorder for brake actuation at preset min distance
Inventor: GERHARD WALTER
IPC: B60T7/12
Filed: 1973-07-10
Abstract: If the distance between the vehicles becomes less than an adjustable predetermined distance without the operation of the brake pedal by the driver the control unit opens a valve connected to a vacuum in the inlet manifold, which then operates upon the brake pedal via a low pressure cylinder and applies the brakes. A second connection from the control unit also sets the carburettor or fuel injection pump into the idle position. With subsequent operation of the brake pedal the automatic brake unit is switched off and the driver has full control over the vehicle again. Removal of the foot from the brake pedal activates a microswitch to switch the radar unit on again.
Patent DE-2338101-A1 (DE)
Title: Two membrane flow switch for water heater - has concentric membranes separated by concentric fixed solid plate
Inventor: HOENESS HANS
IPC: F23N1/08
Filed: 1973-07-27
Abstract: The switch has a lower casing with water inlet and outlet. It contains a circular membrane between high and low pressure chambers, and controlling the water inlet valve. An intermediate casing and an upper casing grip a second membrane between its own high and low pressure chambers and which controls the gas burner valve. The bottom plate of the intermediate casing separates the low pressure chamber of one membrane from the high pressure chamber of the other and a passage in the bottom plate puts the two high pressure chambers into communication with each other. The passage has a throttling effect which delays the opening of the gas valve after the opening of the water valve but damps oscillations of the membranes.

Patent DE-2403750-A1 (DE)
Title: Gate valve sealing slides - are expanded against housing in closed position by wedge to give high pressure seal
IPC: F16K27/10
Filed: 1974-01-26
Abstract: A gate valve has a high performance sealing arrangement to provide total sheet off when operating against high fluid pressures. Inlet and outlet ports (33) are sealed from each other by two rectangular slides (4, 5) with 'O' ring face seals (7). A wedge (10) is located between the two slides and may be moved vertically by a threaded rod (12) operated by a hand-wheel. When the wedge is moved downwards the slides also move to close off the flow through the valve. Eventually the slides contact stops and further motion of the wedge expands the slides forcing the seals into contact with tube surfaces to provide a total seal. When opening the valve the wedge alone moves upwards releasing pressure on the seals before a bridging plate is contacted to start lifting the slides.
