Patent GB-2045982-A (GB)
Title: Reaction Time Tester
IPC: A61B5/16
Filed: 1979-12-18
Abstract: A reaction time tester comprises an electronic chronograph with crystal controlled oscillator, f divider, counters and digital elapsed time display down to 1 m.sec. Any variation of two optical stimuli by LED light sources 33, 34 (Fig. 5) of different colours and two variable intensity acoustical stimuli, may be selected. Tape recorded "white noise" may be continuously transmitted to simulate industrial noise, which can cause fatigue and affect reaction time. An automatic unit enables measurement by the chronograph of the elapsed time between stimuli transmission and response by the person under test. Stimuli is transmitted at random intervals, with minimum interval of 500 m.secs., to avoid conflict with response to the preceding stimuli signal. Total test time is also measured as an indication of monotony tolerance. The initiation of sound transmission is synchronized with zero crossover of the sound sine wave, to eliminate sudden transient effect at the moment of switching on. A digital printer records results on paper strip. <IMAGE>

Title: Radar processing apparatus
IPC: G01S7/292
Filed: 1980-06-04
Abstract: A radar processing apparatus, for distinguishing moving target data from false data, comprises a plot extractor 3, a data store 5, a central control 7 and a comparator 9, 11, 13 and 19. For each one of a number of consecutive scans, extracted plot data, corresponding to a common area of the scan cover, is used by the control 7 which provides information representing the presence or absence of a plot at positions measured across the common area. This information, derived from each scan, is correlated by the comparator 9, 11, 13 and 19 to determine the coincidence of plots lying within each one of a spectrum of resolved component velocity ranges and the results of this comparison used to derive a code for labelling each plot extracted from the most recent scan. One form of the comparator comprises the combination of a number of shift registers 19 having comparator circuitry 13 connected to their terminal stages, the arrangement of these connections defining one or more of the velocity ranges. <IMAGE>

Title: Protective garments
IPC: A41D13/00
Filed: 1980-06-25
Abstract: Garments are described for use in the occurrence of attack to protect the wearer from contaminants reaching the skin or the lungs, to minimise risk of injury. One preferred garment is a jacket 1 with integral hood 2, the outer fabric being made of butyl rubber coated nylon. Internal inserts of an air filtering material such as charcoal impregnated foam or cloth are strategically positioned in discrete portions at each location where air can enter the garment. Such inserts at the waist 4, outer sleeve 3, and hood 2 areas are adapted to form a close fit between the wearer and the garment. The garment, being impermeable to air, allows displacement of contained air at the extremities, consequently contaminated air is drawn in at the same locations and is filtered by the close fitting inserts. <IMAGE>
Patent GB-2082025-A (GB)
Title: Clock extraction
IPC: H04L7/04
Filed: 1980-08-12
Abstract: In a PCM digital transmission system, clock is conveyed by a pilot tone sent with the PCM, the pilot tone frequency fp having a preset relation to the PCM bit rate. This PCM + fp signal is applied via a sample and hold circuit (3) to one input of a subtraction circuit (4). The PCM + fp signal is also applied via a narrow pass-band filter 1 to a phase locked loop 2 whose output fo has a preset relation (e.g. one quarter) to the fo, and is a square wave. This is applied to two adaptive coefficient generators, in one case direct and in the other case via a one unit delay (7). Each coefficient generator is also fed with the circuits' PCM output, and includes the sequence of a multiplier (8), integrator (9) and multiplier (10). The outputs of the coefficient generators are summated by a summation circuit (5) whose output is applied to the other input of the subtraction circuit, whose output is thus the PCM minus the pilot tone. <IMAGE>

Title: Meshing screw compressor
IPC: F04C18/08
Filed: 1981-06-30
Abstract: In a double-entry screw compressor i.e. having two pairs of oppositely pitched rotors disposed end-to-end, both the male or main rotors H1 and H2 and the female or secondary rotors N1 and N2 are mutually angularly offset. The offset is up to one half of the screw pitch; and the rotor profiles are asymmetric. This arrangement ensures that fluid being compressed is not trapped in closed pockets T on one side of the abutment plane of the rotors, since the pockets T are vented via an opening(s) D1 and/or D2 to the grooves in the rotors on the other side of the said plane. <IMAGE>

Title: Oscillating retroreflector
Inventor: BERG CHARLES ADOLPH
IPC: G02B5/124
Filed: 1981-08-21
Abstract: At least two planar reflecting facets intersect at an angle and are mounted for adjustment of the angle between the adjacent facets. At least one facet (52, 53) is oscillated to sweep the angle between   pi  DIVIDED 2  and   pi  DIVIDED 2- delta  radians. The angle  delta  is selected so that the plane of maximum areal energy density crosses the plane which includes the source. This apparatus thus compensates for the effects of dispersion with known retroreflectors. <IMAGE>

Title: Process for making a fibre-reinforced moulding
Inventor: GRIFFITHS PETER MORGAN
IPC: C08J5/04
Filed: 1982-06-21
Abstract: A fibre-reinforced moulding is made by wrapping a core of reinforcing fibres such as carbon and/or aromatic polyamide fibres with a thermoplastic yarn, and thermoforming the wrapped yarn so that the thermoplastic yarn becomes a polymer matrix around the reinforcing fibres. Additional thermoplastic yarn may be included in the core. The wrapped yarn may be converted into a fabric prior to the thermoforming step, and additional thermoplastic yarns for contributing to the eventual polymer matrix may be incorporated in the fabric, for example as alternate warp or weft yarns in a woven fabric. Unidirectional reinforcement may be achieved by having the wrapped yarn only in the warp or the weft, with thermoplastic yarns comprising the rest of the fabric.
