Title: Measuring apparatus for checking the spring strut of a vehicle front wheel suspension
Inventor: NILSSON LARS-ERIK
IPC: F16F9/32
Filed: 1981-06-19
Abstract: According to the invention, simple measuring apparatus is produced which is designed to ascertain if the so-called spring strut (50) of a vehicle front wheel suspension has been deformed, or more specifically if it has been bent, the apparatus being designed to be used primarily on wheels equipped with disc brakes. The apparatus is used in situ, i.e. on a spring strut (50) mounted in place in the vehicle, and it is necessary only for the wheel to be removed, with the tyre and rim, so that the disc brake (40) is exposed. The measuring apparatus consists of an upright (12) which is attached to a base part (14, 20) designed to be attached, preferably by means of permanent magnets (24, 26) to the outside of the brake disc (40). The upright (12) bears movably a measuring arm (30) equipped with a length scale and projecting out from the upright (12) at right angles to the plane of the brake disc (40); this arm also bears movably a pointer device (36) which can be made to seek out the centre (60) of the upper fixing (55) of the spring strut (50) in the bodywork. After this adjustment, the perpendicular distance (a) from the said fixing centre (60) to the plane of the brake disc (40) can be read off on the scale on the measuring arm (30). From the knowledge of this distance it can be established whether or not the spring strut (50) has been deformed or bent. <IMAGE>

Patent GB-2082778-A (GB)
Title: Volume Measuring Apparatus
IPC: G01F17/00
Filed: 1981-08-21
Abstract: A measure of an unknown volume V of, for example, a cavity is achieved utilising a pressure transducer 36 which monitors the rate of pressure rise in the unknown volume when gas from pressure regulator 30 is introduced into that volume, via valve 34. Where the flow of gas can be kept constant, by constant mass flow controller 32, an output signal representative of the unknown volume V is achieved by differentiating and inverting the output of the pressure transducer. Alternatively, a variable gas flow can be measured and an output signal representative of the unknown volume achieved by dividing the measured flow by the rate of pressure increase as monitored by the transducer. <IMAGE>

Title: High performance radio antenna
IPC: H01Q19/13
Filed: 1982-02-05
Abstract: In an antenna having a parabolic reflector 1 and an offset feed 2, the reflector is distorted to produce an elliptical footprint by decreasing its curvature with respect to the true parabola about the plane through the axes of the reflector 1 and the offset feed 2. In other words there is no distortion of the reflector curvature in this plane, i.e. the x, z plane, and there is maximum distortion of the curvature in the plane at right angles to it, i.e. the y, z plane as shown in Figure 3. With this arrangement when the reflector is illuminated by a linearly polarised feed the additional cross-polarised field components generated by the distortion interfere destructively with normally generated cross-polarised field components, resulting in a significantly reduced level of overall cross-polarisation. <IMAGE>

Title: Communications security system
Inventor: COX HERBERT EDWARD
IPC: H04K1/00
Filed: 1982-08-05
Abstract: Communication, eg of a race commentary over telephone lines to a betting shop, is verified by transmitting a verifying data signal of a bandwidth substantially equal to the speech bandwidth. The period between transmission of the verifying data is randomised, eg by transmitting the verifying data signal during the first period of silence in the speech during each of a series of successive time frames, eg of 5 secs duration. In a preferred embodiment the verifying data includes an identity signal and a time reference signal. The receiver compares the received identity signal and time reference signal with respective signals generated by the receiver (4, 5) and an alarm is produced if variance occurs between any of the compared signals. Various aspects of synchronisation between the transmitter and the receiver are disclosed.

Title: Fibre optic cables
Inventor: SPICER LYNDON REGINALD
IPC: G02B6/38
Filed: 1982-09-15
Abstract: A joint between two optical fibres (5) is made by means of a connector (1) formed of a memory metal. The fibres are inserted into a bore (6) from opposite ends thereof whilst the connector is at a first temperature at which the bore (6) is of a larger diameter than the fibres. The connector is then caused or allowed to achieve an optical fibre working range temperature, at which the bore assures a memorised diameter smaller than the fibre diameter, thus clamping the fibres therein. Preferably the memory metal is an non-reversible one and the first temperature is lower than the working temperature range, for ease of connection in the field. Bore 6 may be drilled with a laser and silvered. Cables with two optical fibres may be joined (Figure 2, not shown). <IMAGE>

Title: Electrical circuit
Inventor: LOMAX STANLEY
IPC: G01K1/02
Filed: 1983-12-10
Abstract: An electrical circuit is used to evaluate a voltage drop across an electrical component, for example a resistor RT. The resistor is connected between a source 10 of constant current and a common voltage line (11). Respective input terminals (11, 11') of a first operational amplifier (12) are connected across the common voltage line (11) and the end E1 of the resistor. Respective input terminals (I2, I2') of a second operational amplifier (13) are connected across the common voltage line (11) and the opposite end E2 of the resistor. The output of the second operational amplifier (13) is coupled to the input terminal I1 of the first operational amplifier (12). The output voltage VOUT of the first operational amplifier is the voltage drop across the resistor and is substantially independent of any lead resistance (RL1, RL2). This principle can be applied in the measurement of the voltage drop across a selected one of a plurality of electrical components and finds particular application in multi-point temperature measurement. <IMAGE>

Filed: 1984-07-30
Abstract: An approximately annular part 12 is in use secured over an outlet, e.g. in a window pane, with a central aperture in part 12 in register with the outlet. A plate 34 is spaced from the part 12 on the side of part 12 remote from the outlet, the part 34 being supported from the part 12 by four pillars 36 at the peripheries of parts 12 and 34. An intermediate part 38, in the form of a circular lens, is supported centrally between the members 12 and 34. Air currents striking the unit on outwardly of the outlet produce a depression in the region of the outlet which will draw fumes etc. from the outlet through the aperture. Webs 140 extending between the part 12 and the plate 34 on diametrically opposite sides (Fig. 8) enhance the extraction effect of the unit in response to striking air currents. A bracket and a mounting adaptor for the unit are described (Figs. 9 to 12). <IMAGE>
