IPC: B60T8/22
Abstract: 1,051,484. Fluid-pressure brakes. VYZKUMNY USTAV PRISLUSENSTVI MOTOROVYCH VOZIDEL. April 2, 1964 [April 2, 1963; March 2, 1964], No. 13617/64. Heading F2F.  In a device for varying brake pressure in dependence upon the dynamic loading of a vehicle provision is made for adjusting the sensitivity of the braking action at the start of braking, the system including an actuating chamber 2 and an equalizing chamber 5, a piston 13 operating in the equalizing chamber forming the fulcrum for one end of a doublearmed lever 14 which compensates the dynamic loading of the vehicle, a tubular member 8 having at its bottom end a closure surface 10 to form a valve to co-operate with an air venting tube 6, a second closure surface 11 being disposed substantially in the centre of the tubular member 8 to form a valve controlling the flow between a pressure medium supply reservoir 7 and a working chamber 3 leading to the brake cylinder, the top end of the tubular member merging into a piston 9 of a differential pressure chamber 12. Operation of the brake pedal (not shown) causes the pressure in the actuating chamber 2 to rise and an upward force is applied to a piston 1 to raise the lever 14 and cause the air vent tube 6 to engage with the closure surface 10 to prevent pressure medium flowing from the working chamber 3 to atmosphere. The tubular member 8 is raised to allow the closure surface 11 to open and allow pressure medium to flow from the chamber 7 to the chamber 3 into the brake cylinder. At the same time the pressure medium is fed via a line 4 to the compensating chamber 5 until the forces operative on the piston are equalized. As soon as equilibrium has been reached the closure surface 10 seats and closes the path for pressure medium from the chamber 7 to the chamber 3 and the pressure corresponds to the instantaneous dynamic loading of the vehicle. When the brake is released, the pressure in the chamber 2 drops almost to zero so that the residual pressure in the brake cylinder and therefore in the chamber 3 together with the spring 17 moves the piston 1 downwards to disengage the tube 6 from the surface 10 and allow the chamber 3 to communicate with atmosphere. The differential chamber 12 is provided to reduce the resistance operative at the start of braking.

Abstract: 1,069,673. Controlling aircraft. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. June 10, 1964 [June 11, 1963], No. 24105/64. Heading B7G. [Also in Division G1] An aircraft control stick is mounted in a ball- and-socket joint of which the ball consists at least partly of magnetic material and is surrounded by electromagnetic sensing elements. In one embodiment (Figs. 1 and 2, not shown), an aluminium ball (11) has ferromagnetic laminations (17) cast in it and is surrounded by four exciting electromagnets (19, 20, 21, 22) each flanked by a pair of pick-off coils (24-31), the coils of each pair being connected in series, and the pair being connected in opposition with the opposite pair to form two sets producing signals representative of the stick movements in two co-ordinates. To ensure zero signal when the stick is central, a switch (23) is provided operated by a member (32) which engages a recess (33) in the ball when the stick is centralized. To provide control about a third axis, a further set of exciting and pick of coils is provided (Fig. 6, not shown), concentric with and external to the coils (19-22, 24-31), and a rotary control member of ferromagnetic material is located inside it. In another embodiment (Fig. 4, not shown), a permanent magnet (34), with polepieces (35, 36), is disposed in the ball, and four Hall crystals (40, 42) are arranged around the ball in a body (38) of substantially square internal section. As the stick is moved, the magnetic flux through the crystals varies and the E.M.F. generated by them varies. Opposite crystals are connected in electrical opposition to provide signals in two coordinates.

Abstract: 1,230,227. Cutting apparatus. WIMBLEDON ORGANIZATION Ltd. 30 Dec., 1968 [29 Dec., 1967; 12 Dec., 1968], No. 61615/68. Heading B5A. [Also in Division A3] A machine for marking and cutting stockings prior to assembly into tights, comprises at least two forming blocks 14a, 14b for receiving stockings and mounted on a rotary support 12 adapted to occupy two diametrically-opposed positions in which a translatable cutting member 5 and a marking member 31 may respectively cut and mark the stockings. To commence an operational cycle, a user pulls a stocking over block 14b and presses the starting valve (38) of a pneumatic control system detailed in Fig. 5 (not shown), so that actuator 33 moves marker 31 down on to the stocking; as the marker is lifted from the stocking, actuator 26 releases notched wheel 27 for rotation, and actuator 21 extends to drive blocks 14a, 14b through 180 degrees via ratchet 22 and gear-wheels 24, 25, Fig. 1 (not shown). The blocks, which rotate about axis 13 of gear-wheel 25, are locked in position by the return of actuator 26; actuator 21 reverts to its original position, and actuator 6 moves a cutter 5, mounted on slidable carriage 4, from left to right and back to make a longitudinal cut in the stocking. The stocking is then removed and the cycle may be restarted. The cutter 5 is preferably an electrically heated wire, which also fuses the nylon or like stocking material to prevent unknitting; alternatively a burner or a razor blade, knife or the like may be used. A counter may be provided to record the number of stockings cut. In another embodiment, Figs. 6 (not shown), an electric motor replaces actuator 21. The cut stockings may be assembled into tights or the like, with or without gussets.

Abstract: 1,230,613. Correcting rail position. F. PLASSER. 12 July, 1968 [13 July, 1967], No. 33380/68. Heading B7N. In an arrangement for correcting the lateral position of a railway track, spring-back of the rail is compensated for by overcorrection by an amount which is a function of the difference between the actual and required position of the track. In Fig. 2, in which the actual position is shown by full line G and the required position by straight line O, overcorrection by an amount equal to 0À25 times the difference moves the track initially to the broken line R from which it moves by spring back to line O. Contacts on detector 6 which is moved with the rail and co-operates with reference line 7 control via a valve 8 the supply of pressure fluid to the track shifting elements 4. For the duration of the shift, which is a function of the difference between the actual and required positions of the track, pressure fluid is also fed to a piston 12 which moves a slider 14 which cooperates with a series of switches 13. The switch selected when the contacts of detector 6 run free of the reference line 7 controls valve 9 to maintain the supply of pressure fluid to the shifting elements for a period which is a function of the initial difference. The operation may be repeated if the rail does not spring back by the estimated amount.

Abstract: 1,233,447. English / metric indicators. BRITISH AIRCRAFT CORP. Ltd. 23 Oct., 1969 [25 Oct., 1968], No. 50852/68. Heading B3T. An English/metric dial indicator for machine tools incorporates an epicyclic gear comprising a planet carrier 1 mounted on and rotatable with a shaft S, the planet wheels 7 of the carrier meshing with an interval ring gear 5 and a sun gear 61 formed on a member 6 which carries a cylindrical graduated scale 8, the scale being prevented from rotating relative to the member 6 by friction means in the form of balls 14 resiliently located between the member 6 and ring 8. An annular member 3 coaxial with the shaft S is securable to a machine part and carries a unit selector ring 2 which is rotatably mounted on the member 3 to permit approximately half a turn accompanied by slight axial displacement, the ring gear 5 being consequentially displaceable by way of a thrust bearing 11. In the embodiment shown in Fig. 1, a resilient O-ring 13 is compressed between surfaces 52 and 62 on the ring gear 5 and sun gear carrying member 6, respectively when the selector ring 2 is in its right-hand position and is exerting pressure on the ring gear 5 by way of balls 11. In this position members 5, 6 and 7 of the epicyclic gear are locked together and the member 6 carrying the scale 8 rotates at the same speed as the planet carrier 1 and shaft S, the selector ring presenting a mark 16 to the operator, the scale 8 reading in inch units. Rotation of the selector ring through 180 degrees moves the ring to the left, releasing the O-ring 13 and the engagement between cone surfaces 19 and 20 on the gear 5 and annular member 3 respectively locks the gear 5 to the member 3 and hence to the machine part. Rotation of the shaft S and planet carrier now causes rotation of the sun gear 61 and the scale 8 at an increased speed. The selector ring 2 now presents a second mark 17 to the operator the scale reading in metric units. The knurled ring K permits zero setting. In an alternative embodiment the planet gearing may comprise coupled planet wheels of different diameters. Also, a second epicyclic gearing may be incorporated to indicate coarse and fine settings.

Abstract: 1,234,186. Wired television system. COMMUNICATIONS PATENTS Ltd. 4 Sept., 1968 [5 Sept., 1967], No. 40467/67. Heading H4R. A TV receiver used in a wired broadcast system is supplied through an adaptor which includes two oscillators, one of which changes the frequency of the distributed signals so that they can be received by the receiver and the other for generating a carrier-wave signal which can be combined with a distributed sound only signal and received in the absence of a picture signal. The central transmitter 1 includes a picture transmitter 2 providing an a.m. highfrequency wave (4-10 MHz) and an accompanying sound audio-frequency amplifier 3 together with a second sound transmitter 4 providing an f.m. high-frequency wave of 11 MHz. These transmissions are combined in device 5 and distributed on lines 8, 9 which have repeater amplifiers 10, 11. The subscriber's terminals 12, 13, 14 include a TV receiver 14 designed for use with an aerial for receiving signals in the VHF band, e.g. 40- 220 MHz, with the sound and picture carriers being separated by 4À5-6À5 MHz. An adaptor 15 is provided to modify the signals on wires 8, 9 so that they can be received by receiver 14. Adaptor 15 includes a splitter device 18 which passes the audio-frequency signals to loudspeaker 23 through transformer 21 and control 22. The high-frequency signals pass to frequency converter 24 which is supplied by oscillator 26 to convert the H.F. signals on line 19 to V.H.F. signals on line 27. The f.m. sound signal also present on line 27 as a V.H.F. signal will fall outside the receiver pass-band and not be reproduced. To reproduce this sound signal switch 31 is operated to disconnect loud-speaker 28 and connect second oscillator 29 on to line 19 and change the output frequency of oscillator 26. Oscillator 29 generates a carrier wave of picture frequency differing by 4À5-6À5 MHz from the 11 MHz sound carrier which is changed to a V.H.F. signal in frequency changer 24 and applied to receiver 14.

Abstract: 1,264,601. Knitting machines. FRANZ MORAT G.m.b.H. 23 Jan., 1970 [23 Jan., 1969; 13 Jan., 1970], No. 3484/70. Heading D1C. [Also in Division G3] A circular knitting machine has an information carrier 7 read by a scanning device to control one or more devices on the machine, the carrier 7 and the scanning device being moved relatively step-by-step by a motor controlled by a pulse generator 29 synchronised with the needle cylinder. Needles 3 are selected by electro-magnets such as 5, e.g. 24, 36 or 48 uniformly distributed round the needle cylinder. Carrier 7 is a film band, e.g. with transparent or opague dots on an opaque or transparent back ground carried on rollers 9 and is scanned by beams of light from source 13 so that a transparent or opaque dot causes the photo cells to emit or cease to emit signals which are fed to electro-magnets 5. Alternatively the scanner may move past a strip or card forming the carrier. The carrier has a row of dots corresponding to each electromagnet 5. A pulse generator 29 generates for each needle trick or each needle space a signal which is turned into a rectified square wave pulse and fed to a motor 21 to drive roller 9 step-by-step. Alternatively three pulse generators 29, 31, 33 are provided either as described before or optical being actuated by a light source shining through or reflected from holes or reflectors 35, 37 in the cylinder or in bands 38, 40 attached thereto. A switching drum 39 mounted on cylinder 1 and rotated step by step carries trip cams 45, 47 which co-operate with switches 49, 51 connected to the pulse generators 31 and 33. Trip cams 53, 55 on cylinder 1 co-operate with switches 57, 59 connected respectively to pulse generator 29 and the control system 17. The spacing between elements 35, 37 is reduced and increased respectively from 35a to 35b and from 37a to 37b. If needle cylinder 1 is rotated at constant speed and motor 21 is stopped, the knitting is controlled by devices not shown. When trip cam 47 reaches switch 49 to transfer the machine to electronic control, a signal is fed to pulse generator 31 which connects this to motor 21 and starts the scanning device for carrier 7 and at the same moment the past aperture 35b of row 35 passes pulse generator 31. The next aperture to pass is aperture 35a and generator 31 then emits pulses which, as the spacing of apertures 35 diminishes finally correspond to the needle spacing and when aperture 35b has passed switch 57 transfers the supply for motor 21 to timing pulse generator 29. The machine is controlled through one or more revolutions by carrier 7 which is similarly brought to rest gradually.
