Title: Waveform display
IPC: G01R13/40
Filed: 1978-07-24
Abstract: A waveform display comprises an opto electric display having m vertically electrodes and n horizontal electrodes arranged in an mxn element matrix. A series of n different reference binary code voltages V1-n are applied simultaneously, one to each x electrode. The waveform to be displayed is sampled and binary numbers representative of the amplitude of each sample are produced. These binary sample numbers are each converted into one of the reference binary codes and stored for application simultaneously to the Y electrodes, the code so produced being related to both the amplitude value and the order of reference codes on the x electrodes. As a result of the simultaneous application of appropriate binary codes to each X and Y electrode, unselected X Y intersections receive an rms voltage above a display threshold whilst selected X Y intersections making the waveform receive a zero voltage. The opto electric display may be a liquid crystal display or an electro luminescent display. The binary codes may be an ordered series of binary numbers represented by logic zeros and ones, having a period T divided into N bits where n = 2N, or period T divided into L bits and using 2N codes out of a possible 2L codes where L is greater than N and n = 2N. Alternatively the binary code may be a pseudo random series of zeros and ones. <IMAGE>

Title: Composition and method for preparing foams of solid liquescent materials using selected solid particulate substances
IPC: C04B38/02
Filed: 1978-07-28
Abstract: This invention relates to rigid foams of solid liquescent materials e.g. sulphur. The foams are produced from normally solid but liquescent materials by incorporating selected solid particulate substances in solid liquescent material either alone or in combination with conventional blowing agents. The solid particulate substance is one which acts as a carrier for an entity which will function as a blowing agent when the material is in the liquid state but which will not be released from solid particulate substance under normal storage conditions. The solid particulate substance does not undergo physical or chemical change itself to produce a foaming action. Specified solid particulate substances include fluid coke, anthracite coal, silica gel, clay, gypsum, activated alumina, activated bauxite paraffin wax and glass beads. Properties of the foam or cellular structure produced by incorporating solid particulate substances may be varied, by utilizing various particulates, sizes, quantities and procedures, above and beyond those achieved, to impart additional characteristics such as structural strength, surface texture, color, insulative properties, skid resistance and the like.
Patent GB-2006361-A (GB)
Title: Inertia-Responsive Valve Assembly
IPC: B60T8/28
Filed: 1978-09-28
Abstract: In a motor vehicle hydraulic brake system having an inertia-responsive valve assembly 100 provided to interrupt the flow of hydraulic fluid from a master cylinder 11 to brakes 14 via an outlet port of the valve assembly when vehicle deceleration exceeds a given threshold, a pressure- responsive piston 28 in the valve assembly is effective to override the inertia-responsive valve element 26, and maintain fluid communication from the master cylinder to the outlet port when the outlet port pressure exceeds a given value. The outlet port pressure may be applied as hydraulic braking pressure to selected wheel slave cylinders, or as pilot pressure to a pressure modulator such as a proportioning valve. The provision of such an inertia-responsive valve assembly in a hydraulic brake system enables a brake characteristic to be provided which closely follows the ideal brake curve to prevent wheel lock. <IMAGE>

Title: Insulated mould lining for use in phenolic resin foam production
IPC: B29C44/00
Filed: 1978-10-10
Abstract: A process for producing a phenolic resin foam in which a resole resin is reacted with a curing agent in the presence of a foaming agent and the mixture is supported during curing on an insulating base formed by a sheet of thin, flexible material 3 backed by a gas-space. Preferably the insulating base is a mould liner comprising closed gas pockets between layers of a laminate of plastics film e.g. polyethylene. The moulding may be a continuous or batch process. Wastage of materials due to collapse of the foam at the base of the mould is reduced by the process of the invention. <IMAGE>

Title: Method of and apparatus for the measurement of at least one mechanical property of an elastic material
IPC: A61B5/103
Filed: 1979-08-10
Abstract: Young's modulus and/or the internal damping factor of an elastic material is obtained by subjecting an area of the material to a sustained vibration. The presence of the material being tested changes the resonance of a mechanical resonator and determination of the changed resonance peak enables the required elastic characteristics to be obtained. The sample may be subjected to varying tension during testing and can conveniently be vibrated by signals obtained from a variable frequency generator although, preferably, an electronic circuit for vibrating the resonator has a feed-back loop to operate as an electro-mechanical auto-oscillator.

Facilities are provided for eliminating the defects by processing, or for eliminating a defective part of a slab or an entire slab as scrap-iron. These facilities are operated on the basis of the maximum depth of defects of each area and slabs which are partially or partially discarded as scrap-iron are replaced by new slabs in view of the rolling program selected. The slabs from which defective parts have been removed are fed back to the rolling process as new slabs.

Patent GB-2069785-A (GB)
Title: Ratioless logic circuit
IPC: G06F7/503
Filed: 1980-02-12
Abstract: A multiphase phase ratioless logic circuit which can be fabricated from a family of three basic types of circuit elements, or sticks, with an optional fourth type producing a complementary output of the third type. D type flip-flops and binary adders may be fabricated. In a D-type flip-flop (Figure 3), one of each type of sticks is used, comprising a logic array (10, 18, 20 and 22), a precharging MOS transistor (T1, T3, T5, T7) connected to a VDD rail (14) and a sampling MOS transistor (T2, T4, T6 and T8). Each logic array may be different, and perform some more complex function. Each stick output is derived from the source of its respective precharging transistor (T1, T3, T5, T7). An output node (12) of a first type of stick is connected to the logic array (18) of the second type of stick via a transfer and store (TAS) gate (T16) and the output (24) of the second type of stick is connected to the logic array (20) of the third type of stick by way of another TAS gate (T18). A sequence of four non-coincident clock signals K1, K2, K3 and K4 is supplied to the sampling transistors (T2, T4, T6 and T8) of the first, second, third and fourth types of sticks, respectively to read out the outputs of their logic arrays. Precharging transistors (T1, T3, T5 and T7) are also clocked prior to their associated sampling transistors (T2, T4, T6 and T8) to precharge the output nodes (12, 24, 26 and 28). When the sampling transistors (T6, T8) of the third and fourth types of stick, are conductive and one or other logic array output (26 or 28) is "low", then that output is clamped at the VSS rail (16) voltage to provide a reliable "low".

When the voltage across the chamber (9) surpasses a particular threshold voltage element (7) conducts. Control means (14, 15) switches off one rectifying means (6) when it senses this conduction.   A second transformer (11) and a condenser (12) are connected across the chamber (9) and a thyristor 13 controlled by control means (14, 15) short circuits part of the second transformer (11) when an arc discharge in the chamber (9) occurs. The time necessary for cleaning work pieces is decreased, the power supplied differs little from the nominal power and the electric strength of the working chamber (9) is restored quickly. The productivity of the chamber (9) is increased. <IMAGE>
