Abstract: 910,869. Magnetic recording; television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 5, 1961 [Sept. 8, 1960], No. 31862/61. Class 40 (2). A television signal is recorded as to video by the drum-mounted heads 4-7 and as to audio and synchronizing signals by the stationary heads 12, 13 on a second coating on the opposite side of the tape, so that the respective tracks 21, 19, 20 corresponding to the same instant in time of their respective information are recoded in overlapping relationship at the same part of the tape, thus providing for simplified editing and splicing. Wide tracks produced by heads 12, 13 are only partially affected by the adjacent video recordings or by printing from the next tape-turn during storage, leaving an ample margin of signal on playback by heads insensitive to video frequencies, while the frequencymodulated video signals do not fall below 1 mc/s. so that interference by tracks 19, 20 is readily removed by filtering. A further advantage claimed is the use of narrower tape for the same information storage.

[Also in Group XX] The gimbal element supporting the rotor of a rate gyroscope is supported by a frame element for limited angular movement relative thereto about an axis normal to the rotor spin axis, the gimbal and frame elements being of complementary semi-cylindrical shape about the axis of limited angular movement and having axial extensions on which are mounted respectively, the rotor and stator elements of a signal generator. The frame element 10 and the gimbal 11 comprise semiannular yokes 15, 16 connected by elongated members having offset centre portions 12, 13, and are connected at their ends by pairs of crossed leaf-springs 18, 19, the intersections of which define a longitudinal axis normal to the spin axis 20 of the gyro rotor, the housing 21 of which is secured to the gimbal element 13. The annular stator 26 of a signal generator 24 is secured to the frame 10 and the surrounding rotor 27 to the gimbal 11. The stator carries coils 34, 35, 36 disposed in annular slots in the stator core formed by flanges 28, 29, 30, 31, the intermediate flanges 30, 31 having staggered teeth 32, Fig. 9, the pitch of which corresponds to that between rectangular apertures 37 in the rotor. The coils 34-36 may be energized in various ways, e.g. windings 35, 36 may be energised in series or parallel from an A.C. source in which case the output winding 35 gives a signal of magnitude and phase sense corresponding to the magnitude and sense of the relative displacement of gimbal and frame about the longitudinal axis from a neutral position. Alternatively, the winding 34 may be A.C. energized and the output windings connected in series opposition to give a similarly varying output. D.C. energization may be used to give an output proportional to the rate of angular displacement. By energizing all three windings from an A.C. source the device 24 will function as a damper. A device 25 similar to the signal generator 24, is disposed at the other end of the frame and gimbal assembly, and preferably used as a damper or as an accelerometer as above described. The whole assembly is enclosed in an airtight cylindrical case 55, 56, 57 which may be evacuated or filled with an inert gas.

Abstract: 1,150,736. Rotary fluid motors. DOWTY TECHNICAL DEVELOPMENTS Ltd. July 25, 1966 [July 29, 1965], No.32440/65. Heading F1F. [Also in Division F2] A rotary fluid motor, described as a reversible hydraulic motor, comprises a casing 12, Fig.1, having a doublelobed cam surface 13 against which the tips of vanes 17 slidably mounted in radial axially extending slots 16 formed in a rotor 14 are urged and identical valves V 1 , V 2  through which pressure liquid is supplied to and exhausted from the motor so that those vanes operating in the increasing volume working chambers are urged by a pressure at their roots greater than the pressure in the working chambers to sealingly engage the cam surface prior to the rotor rotating. With a reversing valve 21 positioned as shown, pressure liquid from a pump 20 is directed through a line 23 and valve V 1  and returned from the motor through the valve V 2  and a line 24 to a reservoir 26. Valve V 1  is described and comprises a sleeve 37, Fig. 2, loaded by a light spring 42, and formed with lateral ports 39 and a shoulder 40 and a spring-loaded valve 44 whose leftward travel is limited by a circlip 46. Initially the spring-loaded valve 44 is seated on the end of the sleeve 37. When pressure liquid is supplied to the inlet 36 the sleeve 37 and valve 44 are together pushed rightwardly until the shoulder 40 is arrested by a shoulder 41. Pressure liquid then passes through the ports 39 and passages 27, 28 to diametrically opposite arcuate recesses 29, 30 communicating with the slots 16 to urge those vanes in the increasing volume chambers into sealing engagement with the cam surface 13 prior to commencement of rotation of the rotor 14. Subsequently the valve 44 is unseated and liquid which after passing the valve at reduced pressure enters a channel 60 and working chambers 58, 59 of the motor through diametrically opposite inlets 18 with consequent rotation of the rotor. Liquid exhausted from working chambers 63, 64 passes through diametrically opposite outlets 19 and unimpeded through the valve V 2 , the sleeve 37<SP>1</SP> being moved to the left against its light spring by the exhausting liquid, whilst liquid from the decreasing volume slots passes through the ports 39<SP>1</SP> and sleeve 37<SP>1</SP> to exhaust. Relatively short arcuate recesses 53, 54, 55, 56 interposed between the recesses 29, 30, 33, 34 are at all times subjected to pump pressure through either of branches 50, 51 upstream of the valves V 1 , V 2  and a two-way valve 68 to direct liquid to the underside of the vanes for starting.

A dividing head comprises a rotary plate 16 fixed to a spindle 15 and having teeth 24, a control ring 26 coaxial with the spindle and rotatable by means of a handle 28, means for coupling the plate and lever to rotate the former in one direction and a spring-pressed latch 39 locking the plate and lever together in a stationary position by engaging between the teeth on the plate and in a notch on the control ring. The spindle 15 is held in a part-cylindrical, part-conical. bore 17 of a base 11 by an adjusting nut 18, the nut being locked by a screw 19b which closes the gap of a slot 20 in the nut. A sleeve 24 having trapezoidal teeth is secured to the dividing plate 16 and the control ring 26 is rotatably mounted on the base. Oppositely-acting spring-loaded pawls 32, 43 mounted on the control ring and base, respectively, engage the teeth of the sleeve 24 and the spring-loaded pin 39 on the base engages both the toothed sleeve and a notch 60 on the control ring. When the actuating ring is rotated counter-clockwise by the handle 28, an inclined face 42 on the notch withdraws the locking-pin from the toothed sleeve, which is, however, prevented from rotating by the retaining pawl 43. The control ring is rotated until a lug on the handle contacts a stop-pin 31 inserted in one of several screwed holes 30 spaced round the base at intervals corresponding to the number of teeth on the sleeve 24, and is then returned to its initial position. During the return of the handle, the pawl 32 causes the toothed sleeve and, therefore, the dividing plate to rotate through the required angle until the locking-pin engages the notch 60 and the corresponding tooth of the sleeve 24. Setting between the angles provided by the stop-pin holes can be made by a scale on the dividing plate and a vernier on the base, the dividing plate then being held in the adjusted position by a clamp comprising a threaded member moved axially to contact the dividing plate spindle by means of a threaded spindle rotatable by a handle 62. Cover-plates 47, 48 are fitted over the pawl 43 and pin 39 and round the sleeve 24, respectively.
