Title: Pulverulent coating material
IPC: C22C1/05
Filed: 1978-07-13
Abstract: A pulverulent material is obtained composed of particles or agglomerates which do not segregate when the material is projected at high temperature onto a substrate by subjecting a mixture of two or more materials in powder form to heat treatment at a sufficient temperature and for a sufficient time to produce chemical reaction between the materials and temporary softening of the materials. A pulverulent material is thereby formed consisting of spheroidal particles or spheroidal agglomerates. The specification describes the production of pulverulent material consisting of: a cermet of Al2O3, Ni, and Al; a matrix of Ni-Cr alloy containing inclusions of niobium carbonitride; an Al2O3-Cu cermet nucleus surrounded by a surface layer of Al2O3; and TiO2-Al2O3-SiO2.

Title: Automatic gain control arrangement for receiver in DME transponder
IPC: H03G3/20
Filed: 1978-11-07
Abstract: A receiver for pulse-shaped RF signals is disclosed in which the received signals, whose amplitudes may vary from pulse to pulse within a wide dynamic range (e.g. up to about 100 dB), are amplified so that their video output level variations are limited to a predetermined range (e.g. 10 dB) so that only undistorted signals are passed on for further evaluation. To accomplish this, a cascade consisting of a plurality of amplifiers 211-214 in series each having output signal tap is controlled by a logic circuit which selects one of the output taps for connection to a subsequent processing stage 10, through FET switches 281-284. The receiver is especially suitable for use in precision DME transponders. <IMAGE>

Patent GB-2063784-A (GB)
Title: Twin axle suspensions
IPC: B60G5/053
Filed: 1979-11-29
Abstract: A pair of axles 18,19 are located in a vehicle chassis by a radius frame 20,21 and leaf springs 13,14. The leaf springs one each side of the vehicle are pivoted at their centres equally dividing the load between the axles, and form locating links for the extremities of the axles in a fore-and-aft plane. The radius frames further locate the axles fore-and-aft and also provide sideways location. All rotating joints are resiliently mounted. This arrangement allows vertical axle movement, fore-and-aft articulation, i.e., axles moving vertically relative to each other, and cross articulation diagonally opposite wheels can move vertically relative to each other. Rotational movement of the axles is controlled by the springs and radius frames. The springs do not encounter any sideways slewing forces since these are fed back to the chassis by the radius frames. Braking and driving forces do not change ground loads. <IMAGE>

Patent GB-2069974-A (GB)
Title: Sampling controller
IPC: G01N1/00
Filed: 1981-01-09
Abstract: The sampling controller is an aid to the accurate aspiration of a liquid sample e.g. of blood serum, by means of a pipette, and its subsequent dispensing, possibly with dilution, into a sample receiver. By the use of a movable platform 11 the movement of which is programmable, the presentation to the pipette tip 15 of a sample for aspiration and of a receiver for dispensing, is controlled repeatably. The platform 11, with a sample container or a receiver 12, is raised and lowered by a lead screw 3 driven by a reversable motor 1. The position of the platform 11, and hence of a vessel 12 supported on it, is detected by optical detectors in which a beam of light can be interrupted by a shutter attached to the platform. Signals from the optical detectors are fed to control means, including a microprocessor, and coact with a program therein to operate the platform and sampling and dispensing operations in sequence. <IMAGE>
Patent GB-2073344-A (GB)
Title: Anti-skid vehicle braking systems
IPC: B60T8/1766
Filed: 1981-02-11
Abstract: An anti-skid vehicle braking system includes means for comparing a wheel deceleration signal with a predetermined threshold signal which is variable according to brake actuator pressure and optionally, the load on the wheel. An electronic control unit (13) controls an anti-skid valve assembly (4) for modulating the fluid pressure applied to a brake actuator (7). A wheel speed sensor (9) produces a deceleration signal via a conditioning circuit (15) and a differentiator (17), which signal is compared in a comparator (19) with a deceleration threshold value. A pressure sensor (10) provides a pressure signal corresponding to the current brake actuator pressure and a pressure signal conditioning circuit (24) modifies the pressure signal to take account of a load signal produced by a load sensor (26) which measures the loading of the braked wheel (8). The deceleration threshold value is produced by modulation of a constant threshold value in a threshold generator circuit (22) and a threshold modulator circuit (21) in response to the modified pressure signal. The threshold value is varied in response to the current pressure signal in accordance with a predetermined relationship between the threshold value and the brake actuator pressure, with a higher threshold value being provided for a higher actuator pressure. When the system is applied to the brakes of a low inertia axle, an over-ride circuit (28) is included to provide a signal which over-rides the pressure signal or an initial period when the brake is applied as detected by a brake lamp switch (29). <IMAGE>
