Title: Anti-skid braking system
IPC: B60T8/74
Filed: 1978-10-31
Abstract: The sensitivity of a wheel speed sensor 12 in an anti-skid braking system to wheel deceleration is varied in dependence on braking pressure and/or axle load. The sensor 12 is driven from the wheel through a variable-ratio transmission 18. The transmission ratio being varied by a fluid actuator 56, 58. Suspension movement due to axle loading, results in movement of the actuator, and is transmitted through a Bowden cable 66. Brake pressure is applied by line 54 to move the piston 58. <IMAGE>

Title: Aerial Systems
IPC: H01Q21/24
Filed: 1978-11-21
Abstract: An antenna system arranged to receive, along a direct path, a signal having known rotationally polarised characteristics but which also receives, along an indirect path, the same signal but with differing polarisation characteristics, has an adaptive control means whereby the mismatch of the antenna system response to the signal received along the indirect path is increased to a significantly greater extent than any corresponding increase in any mismatch to the signal received along the direct path. The adaptive control means may include a phase shifter 3 in the path of signals received at one polarization, a power divider 4 at which received signals of orthogonal polarizations are combined, and a computer 6 which receives the fluctuating output signal from a receiver 5 and in response controls phase shifter 3 and power divider 4 so as to reduce multipath interference to a minimum. <IMAGE>

Title: Embossing in register with printing
IPC: B41F19/02
Filed: 1978-12-08
Abstract: A method and apparatus for embossing a pattern on a web, e.g. of wallpaper, in register with an existing printed pattern on the web utilises a tensioning device, e.g. a pair of tensioning rollers 12, to tension and stretch the web 16 upstream of the embossing station. The tension and degree of stretch is adjusted in response to scanner 18, which measures the speed of the web by counting marks thereon, so as to achieve perfect registration of the stretched printed pattern with the fixed dimension of the embossed pattern. The tension may be adjusted by moving the point of action of tensioning rollers 12 with respect to the embossing station, or by varying the speed of embossing cylinder 13. <IMAGE>

Class 100(4) [Also in Group XIX] A contact device on a typewriter for coupling a signal e.g. from a calculating machine, connects contacts C spaced at letter-space intervals, with a source of current 19 and operates appropriate keymagnets 21, 25, 23 in' according with a signal covering the whole entry in a tabulation column I or II &c. and also connects contacts L1. L2, with space key magnet L. When the signal is keyed in the calculating machine a crank handle 28 is also pulled down to close a switch 30 and a series of type racks 11 are longitudinally displaced so that connections are made from place-value contact bars 13 to vertical digit-contact bars 14. As shown. in the Figure the racks are set so that the number 536.07 is typed. A slider 17 of the typewriter carriage 16 connects firstly the 100,000 contact to a bus-bar 20 so that a circuit from the current source 19 is made through wire 15 to bar 13 which is bridged by the rack 11 to a letter-space magnet 25 and carriage is letter-spaced without printing, to the 10,000 space. A further letter-space occurs both here and at the 1,000 space but when the carriage slider 17 reaches the 100 space the corresponding rack 11 is bridged to magnet 5 and that figure 5 is typed. Similar actions occur for the other digits until contacts A at the end of each tabulation column is reached whereupon a stop-solenoid 33 is energized to release the starting handle 28 and restore all the racks to the letter-space contact bar L. The device may be used with one row of place-value contacts with a slider for each tabulation column. Specification 737,928 is referred to.

Title: Video display control apparatus
IPC: G09G5/34
Filed: 1979-07-11
Abstract: Control apparatus for a cathode display tube receives 11 a composite signal conveying raster synchronizing and video information; deflection coils 12 and 13 supplied by line and frame output circuits 17 and 18 thus receive synchronized scanning currents. To adapt automatically the raster to one of two different formats a phase locked loop tone decoder 37 receives the composite signal and indicates by producing a binary output signal whether or not the composite signal includes a line frequency tone within the bandwidth of the generator 37, this tone being the line frequency for one of the two formats while another tone frequency which is outside the bandwidth of the decoder 37 is the line frequency for the other format. This binary signal is supplied to switches 21, 24, 28, 32 and 36 which are respectively set either open or closed depending on the binary signal and thus they adapt the scanning raster circuitry to the component values required for one or the other format. <IMAGE>

Title: Control system for a motor vehicle simulator
IPC: G06G7/70
Filed: 1979-07-18
Abstract: For a simulator producing a simulated view of a road scene on a screen by movement of a model of the scene in accordance with the operation of controls of the simulator which determine a simulated speed and a simulated angle of turn of a steering wheel control, there is provided a control system which produces from these two parameters three signals for moving the model, namely, an x control signal for controlling the speed of movement of the model in an x direction parallel to the screen, a y control signal for controlling the speed of movement in a y direction normal to the x direction, and a W control signal for controlling the speed of rotation of the model about an axis normal to both the x and y directions. At least two of the three control signals are produced by generating two intermediate functions related to the speed and turn angle and then applying one intermediate function to an x operator which operates on said one function in accordance with an x distance of the model from a datum and applying the other intermediate function to a y operator which operates on said other function in accordance with a y distance of the model from a datum. <IMAGE>

Abstract: A water heating system, for example for domestic use, has an evacuated sealed vapour transfer duct (1) through which vapour is transferred from an evaporator section, which may for example be included in a solar heat collecting panel (3), to a water heating vessel (7) in which the vapour condenses, the condensate flowing back to the evaporator section. An automatically controlled pump (38, Fig. 14) may be employed to convey the working liquid to the evaporator via a liquid reservoir (32) if the solar collector is located above the level of the heating vessel. The evaporator section may be integral with an incinerator (30, Fig. 13). <IMAGE>

Title: Band-ratio radiometer
IPC: G01J5/60
Filed: 1980-09-26
Abstract: A band-ratio radiometer for colour temperature measurement makes use of a trifurcated fibre optic bundle (10), over two branches (12, 13) of which the sample radiation is transmitted in different wavelength bands. The third branch (14) is used to direct light from a source (20) onto the target (17) so that the common end of the bundle may be focused precisely upon the target area, with no parallax problem. Conventional optical filters are avoided by use of detectors (18, 19) which are identical in wavelength sensitivity and optical fibres which differ in wavelength transmittance. To compensate for inhomogeneous mixing of the fibres leading to the two detectors (18, 19), the image of the target is scrambled by means of reflections within a transparent rod placed in front of the fibre bundle. <IMAGE>
