Title: Pressure Rupturable Safety Device and Vacuum Support for use Therein
IPC: F16K17/16
Filed: 1980-06-13
Abstract: A vacuum support for use in supporting a rupturable graphite safety disc 2 against flexing when subject to sub-atmospheric pressure on one side thereon, which does not prevent the obtention of maximum free outflow cross-section when the disc is subject to a bursting pressure and can be used thereafter is constituted by a disc 5 made up of a plurality of concentric graphite rings each made up of at least two parts and having a prismatic cross-section, the margins of the cross-section of the rings which lie on prism surfaces being inclined downwards the disc axis at the face thereof which, in use thereof, may be subject to a pressure sufficient to cause rupture of the rupturable graphite disc. Because the separate parts of the vacuum support disc are keyed to one another, when the pressure to which they are subject is smaller than the outside pressure, the disc does not collapse and when the pressure increases, the separate parts are forced against the rupturable graphite disc so as to be forced out of the holder therefor concomitantly with rupture of the safety device thereby to free the entire available cross-section. <IMAGE>

Patent GB-2348756-A (GB)
Title: Radar system
Inventor: PERRETT ANTHONY HANDLEY RUSSEL
IPC: G01S13/10
Filed: 1981-06-10
Abstract: A radar system includes an r.f. oscillator (4) which generates an r.f. pulse (C) having a preset pulse length determined by a timing circuit (2). The pulse is transmitted at T<SB>X</SB>. A portion (C<SP>'</SP>) of the transmitted pulse is fed via a coupler (6) to a mixing circuit (5) which also receives the corresponding radar return (D). The mixing circuit produces a video pulse (E) of length equal to the interval of common occurrence of the portion (C<SP>'</SP>) and the radar return (D). The video pulse is mixed in one channel CH2 with a bipolar video signal (F) having a transition from one polarity to the other occurring within the time interval of the portion (C<SP>'</SP>) of the transmitted pulse but having no transition coincident with the leading or trailing edges of that pulse. The resulting signal G is then passed via a doppler filter (11) and an integrating circuit (13) to a ratio circuit (14). The video pulse E is also fed along another channel CH1 without any mixing with the bipolar signal to the ratio circuit (14). The ratio circuit output signal related to target range, is thereby made less subject to errors in timing of the pulse edges and the bipolar transitions.

Title: Metering valve
IPC: A61M16/20
Filed: 1982-03-12
Abstract: A metering valve which is particularly advantageous for use in gas mixing devices such as patient ventilators, to accurately control the volume and frequency of gas flow for each gas and to provide a feedback of the actual flow through the valve. A valve (82), actuated by solenoid (164) is connected to the core of a linear variable differential transformer (192). As the valve opens, the core (206) of the transformer (90) moves, causing a change in the output voltage from the transformer. The change in output voltage from the transformer can be interpreted by a microprocessor to discern the actual flow through the valve. Two or more of the metering valves can be used to accurately control the mixture ratios of two or more gases. <IMAGE>

Title: Control of character and background colour on video display unit of data processing system
Inventor: SAENZ JESUS A
IPC: G06F3/153
Filed: 1982-08-06
Abstract: In e.g. a personal computer an 8-bit character byte is fetched from a random access memory (30) for each character and applied to a character generator (28). An associated 8-bit attribute bit is also fetched from the random access memory (30) and applied to the inputs of a multiplexer (32). Four of the attribute bits designate the color of the character to be displayed on raster CRT (eg TV) (14). The remaining four attribute bits designate the background color of the character. The eight attribute bits are selectively gated to the outputs of the multiplexer (32) under the control of character serial dots from the parallel-to-serial converter (34) as red (R), green (G) and blue (B) digital color signals which are applied to a composite video signal generator (38). The colors of the font and background of each individual character are thus independently controlled. They may be identical, causing the character to be invisible. <IMAGE>
