Title: Anti-skid brake system
IPC: B60T11/30
Filed: 1980-09-11
Abstract: An anti-skid system is fitted in a brake system which operates with pneumatic pressure at the brake valve (1) and with hydraulic pressure medium at the wheel cylinders (30, 31, 32, 33). A pressure step- up unit (18, 19, 20, 21) is provided for each vehicle wheel between the two pressure media. A common anti-skid pressure-control valve or separate anti-skid pressure- control valves (6, 7) is or are disposed upstream of the pressure step-up units which are associated with the wheels of preferably a common vehicle axle (4, 5). The pneumatic parts (14, 15) of the pressure step-up units (18, 19) intended for the brakes on the front axle (4) are each combined with a respective relief valve which opens when the pneumatic piston has executed its full travel, which only happens when there is a leak from the corresponding master cylinder (22 or 23) or hydraulic line (26 or 27) or wheel cylinder (30 or 31). The pneumatic part (14 or 15) is thereby vented to relieve the pressure at the other intact front brake. The required symmetry of braking is thereby maintained. The anti-skid system is intended for lighter to medium heavy commercial vehicles. <IMAGE>

Title: Forming a connecting socket on a pipe of thermoplastic material
Inventor: RIEGEL KARL-HEINZ
IPC: B29C57/02
Filed: 1981-06-29
Abstract: A method of integrally forming a connecting socket, having an internal groove, on the end portion of a pipe of thermoplastic synthetic material is described wherein the end portion is heated to shaping temperature, is then deformed to increase its wall-thickness until the latter fills an annular gap in a heatable upsetting apparatus, and thereafter is shaped to form the connecting socket during axial displacement in a forming device, and is finally allowed to cool. The method is characterized in that the heating up and preliminary deformation of the end portion proceed from the zone of the free end-face of the end portion and by the use of a relatively narrow shaping- temperature range just below the crystallite- melting temperature of the crystalline or partially crystalline synthetic material, in that the heated-up and preliminary deformed end portion is removed from the apparatus for carrying out preliminary deformation, and in that during the forming of the connecting socket in the forming means, maintained at shaping temperature, the end portion is finally deformed to compensate for reductions in wall thickness that have occurred during expanding.
Patent GB-2105556-A (GB)
Title: A signal transmission system
Inventor: DOWNING ALBERT CHARLES
IPC: H04H20/48
Filed: 1981-08-14
Abstract: In a stereo radio transmitter, should one of the stereo input channels fail, e.g. by being short- circuited, it may be desired to isolate that input from the transmitter and to feed a mono-signal through the other input. In order to do this some form of switch must be provided to isolate the faulty channel from the transmitter and to feed the mono-signal through both channels. The switches S1 to S6 would fulfil this function, but mechanical switches are considered unacceptable and so semiconductor switches need to be used. In accordance with the invention switching devices are inserted in the unbalanced lines downstream of the balanced-to-unbalanced transformers 1A, 1A'. This has the advantage of reducing the number of switches and also minimising the effects of distortion because the switching impedances of the switches are less than the input impedances of the following high-impedance amplifiers 1B and 1B'. This contrast with the much lower input impedances of the transformers 1A, 1A'. The switching devices 1E to 1 H are controlled by signals from a control circuit 6 which can be set to either one of three possible states for normal stereo broadcasting, for conditions where the lower channel is faulty and a mono-signal is being fed through the upper channel and where the upper channel is faulty and a mono-signal is being fed through the lower channel. <IMAGE>

Title: Decoding binary coded colour video signals
Inventor: WONG KWOK KEUNG
IPC: G09G1/28
Filed: 1981-10-28
Abstract: Decoder circuit arrangement for decoding binary coded colour video signals to produce analogue colour video signals therefrom comprising three inputs (1, 2, 3) to which the binary signals are applied these inputs being connected through an analogue level conversion circuit (5) to a selector circuit (6), both of which are provided in an 8-channel analogue multiplexer/ demultiplexer (4), the selector circuit (6) selecting a particular one-out-of-eight outputs (7-14) for application as control signals to the control inputs of individual switches (15-22) which are also provided in the analogue multiplexer (4). The control signal so formed renders the appropriate one of the switches (15-22) conductive. The inputs of the switches are respectively connected to points (A-H) on a potential divider (24-30) energised from a supply input (31) for a voltage supply. The one of the switches which is conductive conveys the voltage at the appropriate point (A-H) to an output terminal (2) of the analogue multiplexer (4) which output terminal is connected through a buffer amplifier to an output (33). The output (33) provides an analogue signal for the input binary signal. The arrangement also comprises two similar analogue multiplexer/ demultiplexer circuits (4', 4"), the inputs to these analogue switches (15-22) also being connected to the voltage reference points (A-H). If the inputs (1, 2, 3) to the analogue multiplexer (4) are red binary coded video signals and inputs (34, 35, 36 and 37, 38, 39) for the analogue multiplexer (4', 4") are respectively blue and green binary coded video signals then the output of the three multiplexers (4, 4', 4") will track due to the use of the common reference supply arrangement. <IMAGE>

Title: Ultrasonic testing
IPC: H03K4/50
Filed: 1980-10-21
Abstract: In order to avoid the necessity for repeated re-calibrations of an ultrasonic testing instrument due to changing dimensions of its electronic components, as well as due to different characteristics of the testing head 22, the material of the test object etc., characteristic data are entered via a keyboard 215 and corresponding digital/values are stored in memory. Data for setting an image field and an echo range gate are also entered via the keyboard. A microprocessor 28 then sends out sequences of ultrasonic pulses of regularly varying rise/fall times and correlates the measured times with a table that permits matching the closest value to the selected data. During actual operation, the traversing time of the sawtooth wave which controls the horizontal beam deflection on a display CRT 25 is compared digitally with a calculated time and a suitable correction signal is applied to a current source which modifies the charging current of timing capacitors so as to match the correct sawtooth traversing time. Additional circuitry provides for on-screen display of the position and dimensions of the range gate (detection window), textual information and other data. <IMAGE>
