Filed: 1962-10-18
Abstract: 976,125. Disc brakes; shoe-drum brakes; fluid pressure control of brakes. ROLLSROYCE Ltd. Oct. 11, 1963 [Oct. 18, 1962], :No. 39539/62. Headings F2E and F2F. In a vehicle braking system the pressure of fluid supplied to a braking mechanism is controlled between predetermined minimum and maximum values by control means responsive to the coefficient of friction exciting between the rim or tyre of a wheel and a member adapted to be brought into contact with the rim or tyre so that the pressure is varied in proportion to the value of the said coefficient of friction. As shown, the pressure supplied from a conventional compressed-air railway braking system, including driver's valve 29, control and auxiliary reservoirs 28, 24 and triple valve 22, to the brake cylinder 19 of a disc brake 13 is controlled by a valve 31. The braking pressure supplied from the valve 22 is also communicated to a brake cylinder 47 which acts to apply a shoe 43 against the rim of the braked wheel 10. The shoe 43 when applied against the wheel moves an angular distance proportional to the coefficient of friction between the wheel and itself to vary via link 41, pivoted lever 40, cam 39, roller 38 and piston 36 the spring-loading of pressure relief valve 32. In another embodiment the pressured compressed-air passing through a valve having variable spring-loading is communicated via a triple valve to the brake cylinder 19.

Abstract: 982,328. Telegraphy. GENERAL ELECTRIC CO. Ltd., N. E. HEAD, and J. M. SMART. Feb. 8, 1963 [Nov. 8, 1961], No. 40086/61. Heading H4P. Malfunctioning of parts of an equipment for generating a signal which at any instant has one of a small number of values, e.g. a binary signal, and which comprises data at some time intervals and other information, e.g. parity, at other intervals is detected by an arrangement which is operated by digits occurring during said other intervals. The Specification describes transmitting and receiving apparatus identical with that disclosed in Specification 982,326. The signal generated comprises a group of 12 sub-groups each of 12 bits. During these 1st and 12th bit periods a bi-stable circuit at the transmitter should be in its 1 state, if it is not this circuit or part of the apparatus prior to its malfunctioning. When the circuit is in its O state gate 102 is enabled to permit a pulse B12, occurring during the 12th bit period, to trigger bi-stable unit 104. The output of 104 passes to slow-acting relay 107 and also resets 104. A second trigger pulse arriving during the next 12th bit period causes relay 104 to be energized and lamp 108 to be lit. To detect single faults the pulse on line 103 is caused to trigger unit 110 to actuate relay 111 which lights lamp 108. By selecting by switch 101 an appropriate one of the sub-group counter pulses C1-C12 the sub-group in which the malfunctioning occurs can be determined, lamp 118 being lit when that sub-group is selected. Specification 982,327 also is referred to.

Title: Improvements in or relating to pulsed rador transmitterreceivers
IPC: G01S13/24
Filed: 1958-12-16
Abstract: 889,485. Radar. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 16, 1958 [Dec. 19, 1957], No. 40538/58. Class 40(7). A pulse radar transmitter-receiver which repeatingly transmits a sequence of pulses, each pulse in the sequence having a carrier frequency different from those of the other pulses, comprises a number of receivers, each tuned to one of the several carrier frequencies and each controlling a cathode-ray display system. Displayed target echoes are increased 'in intensity over random noise by superimposing the scans of the display systems. Each display system may be either a separate cathode-ray tube together with an optical system so that the traces on the several tubes appear superimposed, or a multi-gun cathoderay tube arranged so that the traces from each gun, fed by an individual receiver, coincide. In an example of the latter method, three transmitter-receiver units are used, T1-R1, T2-R2, T3-R3, the receivers being connected to the guns K1, K2, K3, of the display tube CA. The transmitters are controlled by a pulse generator SG and distribution device TS. The yarious scan time-bases are triggered by the corresponding transmitter pulse. To reduce the effect of breakthrough from one transmitter to a receiver operating on a different frequency, the transmitter trigger pulses are cyclicly varied in phase so that breakthrough does not occur at the same point on each scan and therefore does not integrate due to repeated painting on the same part of the display screen. Phase shifters Dl, D2, D3, are provided, controlled by a three-phase generator WG, and may comprise multivibrators which are triggered from one state by the pulses from the device TS and remain in that state for a duration dependent on the control voltage from WG. The return of each multivibrator to its original state triggers the respective transmitter.

Title: Procedure and device for synchronising cinematographic cameras with projectors

Filed: 1972-09-18
Abstract: 1355756 Cinematography BOLEX INTERNATIONAL S A 18 Sept 1972 [16 Sept 1971] 43210/72 Heading G2E To correctly synchronize the film transport speeds used during filming and subsequent projection of a cine film, a camera is used that marks the film such that a projector, carrying a monitor to sense these marks, may adjust automatically the film drive of the projector or so that the monitor indicates to the projectionist the required rate of film advance. The film may be marked magnetically or optically. If optical marking is used the film may carry marks of differing intensity or colour, the latter being preferred since it is independent of dust in the monitor attenuating the sensed intensity of a mark. To optically record a mark, when filming, a selected colour filter is aligned adjacent the film edge at the picture gate. A set of colour filters may be conveniently provided around the periphery of a rotatable disc, Fig. 2, 2A (not shown). To optically produce marks of varying intensity a constant intensity source is directed on to the film edge at the picture gate. Thus at different film advance rates the mark produced will be of different intensity due to the different exposure times of the film to the source, Fig. 1 (not shown). Fig. 3 shows a monitor in a projector sensing a colour marked film. The marked film edge is aligned with apertures 21, 22 and illuminated by source 17. Semi-reflecting mirrors 23, 24 and mirror 25 direct the image of the mark on to red, blue and yellow filters 26, 27, 28 respectively. Photo-electric transducers 29, 30, 31 are selectively activated (singly, e.g. by a red mark, or in combination, e.g. by a green mark) to control impulse generators 35, 36, 37 powering electromagnet 38 attached to a film advance claw. Threshold switches 32, 33, 34 prevent unrequired operation of the generators 35, 36, 37. To monitor variable intensity marks only one transducer is required, this being connected to several control circuits for the film drive. Only one such circuit can be activated at a time, the selected circuit depending on the mark intensity.
