IPC: G01R13/40
Filed: 1983-07-28
Abstract: A meter display (Figs. 1 & 2) in which the main scale (M,E) is supplemented by a dial-shaped scale formed by the common area of overlap between electrodes (V,EV) mounted each side of an electro-optically responsive medium, one set of electrodes (V) being comprised of several segments (V0???,V9). On one side of the medium, the main scale electrodes (M0???,M9) may likewise be of segment form and the main scale of vernier scale electrodes interconnected. Identical waveform select address may be used - eg the address may be by pseudo-random binary sequence signals. The above may be used in conjunction with a digital display for measurement of signal extrema. A pseudo random binary generator applies a set of isogonal signals to the main scale segments M0-M9 and to the vernier scale segments V0 to V9 and to a multiplexer gated by BCD data. The multiplexer selects one of the signals for application to the vernier electrode EV. The vernier scale display is also indicative of whether the measured signal is increasing, decreasing or approaching a stationary value. <IMAGE>

Title: Releasing spring-applied parking brake by service brake pressure
Inventor: BULL IVOR HENRY
IPC: B60T13/66
Filed: 1983-08-24
Abstract: In a vehicle brake system, particularly for a railway vehicle, the parking brake (1) is released by an effective service brake (2) application by distributor (13) which causes fluid pressure from reservoir (10) to be applied via step-up relay (7) and two-way valve (4) in opposition to the force exerted by the parking brake spring. Subsequently, build-up of service brake pressure closes switch (17) whereupon valve 4 is switched over and parking brake (1) is maintained released for normal running by fluid pressure derived from a main pressure reservoir (5). The two-way valve (4) is held switched over by an electrical self-maintaining circuit, including relay (16, 18), in the normal running position thereafter. The system avoids excessive compounding of the brake forces while allowing release of the parking brake automatically when the service brake is applied. <IMAGE>

Title: A seismic exploration system and an analog-to-digital converter for use therein
Inventor: SHIRLEY THOMAS EDWARD
IPC: G01V1/24
Filed: 1983-11-03
Abstract: An analog-to-digital converter especially suited for seismic data recording applications operates using the differential pulse code modulation method. A digital linear predictor 40 is used to generate a digital predicted input signal, which is converted in a digital-to-analog converter 44 to an analog signal which is directly compared to the actual input signal 42. The error signal thus generated is converted 34 to a digital error signal for addition 38 to the predicted signal prior to transmission to means for recording the output signals, and is used for updating of the predicted signal according to the linear predictor 40. Quantization noise is reduced by highly oversampling the input signal, and a low pass filter 46 smooths the digital output signals. <IMAGE>

Patent GB-2153707-A (GB)
Title: Electromagnetic rotary separator
Inventor: BARWELL FREDERICK THOMAS
IPC: B03C1/247
Filed: 1984-02-10
Abstract: A combination of electromagnetic and centrifugal forces is used to separate materials which conduct electricity from those which do not. In a preferred apparatus, material is fed by guides 1 and 2 into an annular shaped region of space 3 which is swept by a rotating electro-magnetic field generated by poly-phase winding 4. This field cases currents to flow within conducting particles of matter which will in turn react with the field producing forces which cause those particles to move in consonance with the rotating field. The accompanying centrifugal acceleration will cause the conducting particles to fly tangentially outwards whereas the non-conducting matter, being unaffected by the rotary action, will continue to move under the action of gravitational force in an undeflected path. The trajectories of conducting and non-conducting particles will therefore become differentiated by a powerful action and the two streams of material can be separated by suitably placed baffles 5. <IMAGE>

Title: Method for the selective recovery of constituent materials from insulated-electrical-cable wastes
Inventor: PELLEGRIN ROBERTO
IPC: C08J11/08
Filed: 1985-03-18
Abstract: Waste from insulated electrical cables, including metal conductors and plasticized polymeric material consisting at least in part of plasticized polyvinyl halides is treated with a solvent to extract selectively the plasticizers in the polymeric material. The solution containing the extracted plasticizer is separated from the solid waste material and fed to a distillation plant. The deplasticized polymeric material is then subjected to cold crushing. The method is particularly advantageous in connection with the recovery of waste in which the plasticized polyvinyl halides are mixed with olefin polymers. The removal of the plasticizers permits the selective cold crushing of the polyvinyl halides and their recovery and also permits the crushing to take place at a temperature only slightly below 0 DEG C instead of about -45 DEG C with consequent saving in cost.
