Abstract: 1,065,452. Endless conveyers. GENERAL PRECISION SYSTEMS Ltd. March 18, 1964 [March 29, 1963], No. 12594/63. Heading B8A. [Also in Divisions G4 and H2] A conveyer belt embodies modules which include movable permanent magnets 2 whose orientation is used for controlling the removal or diversion of articles being conveyed. Each magnet is contained within a capsule 1 of non- magnetic material and soft iron inserts 4 are contained in abutments 3. The magnet is thus releasably held in one or other of two extreme positions, respectively, along and across the direction of travel of the belt. These positions correspond respectively to the states " 0 " and " 1 " in the binary coding scheme. A write-in assembly, Figs. 3, 5 (not shown), using 6-bit identifying code signals comprises six write-in units (6) for setting the magnet position of the passing capsules (1). Each unit comprises a stationary U-form electromagnet with its poles close to the underside of the belt (5). By appropriate polarity energization, the units (6) may impress " 0 " and " 1 " at choice. A permanent bar magnet (11) ensures that all the magnets arriving at the write-in assembly are initially in their longitudinal " 0 " setting. For subsequently sensing the orientation of the capsule magnets, a read-out head comprises six dry-reed magnetic switches (8) connected in series, these sensors being positioned either along or across the direction of travel of the belt. In Fig. 5, the sensors are arranged to embody the signal 001001. Only when a passing article is accompanied by this signal will all the switches of the head be closed to initiate removal or diversion of the article. In place of the capsules, voids containing the magnets may be formed directly in the conveyer belt.

Patent GB-501996-A (GB)
Title: Improved method of and apparatus for locating distant objects such as aircraft
IPC: G01S1/02
Filed: 1938-04-28
Abstract: 501,996. Locating objects by reflected waves. SPERRY GYROSCOPE CO., Inc. April 28, 1938, No. 12679. Convention date, April 29, 1937. [Class 37] [Also in Groups XL and XXI] Directive aerials are rotated to scan the outlook both horizontally and vertically in order to locate the position of a distant wireless transmitter (or the position of an object capable of reflecting wireless waves) and show it as a spot of light on the fluorescent screen of a cathode ray indicator. More than one such object may be located simultaneously. The apparatus can be used to " spot " invisible aircraft, to avoid. collisions in the air, to assist in blind-landing, and to control gun-fire. In Fig. 2, one directive aerial 2 is rotated at a " framing" speed about the vertical axis, and a second similar aerial 4 is rotated at " line " speed about a horizontal axis, both being driven through gearing from a motor 8. The same motor synchronously drives contact arms 10, 21 over semi-circular potentiometer resistances 11, 27 respectively so as to supply scanning voltages, which foloow the orientation of the aerials, to the deflecting plates 16, 17 of a cathode-ray tube 18. The cathode-ray tube is normally biassed to "cut-off" but its control grid is fed with the varying signal voltage picked up by the aerials from the distant transmitter (or reflector) as soon as this rises above a level sufficient to activate a biassed valve 48 in the output of the wireless receiver. A resistance 42 in the plate circuit of that valve, and in the control grid circuit of the cathode-ray tube, serves first to remove the cut-off bias from the latter and then to control the intensity of the electron stream in accordance with the received signal strength. In this way the position of the distant transmitter is shown as a spot of light on the fluorescent screen, the spot only being produced when both antennae are energized. During the rear half of the aerial rotation, two arms 26, 31 move over conducting segments 25, 30 (associated with the " sweep " potentiometer 11, 27) so as to short circuit the resistance 42 and put the cathode-ray indicator out of action. The two parabolic aerial-reflector systems may be replaced by a single one, mounted to rotate universally, or by two pairs of directive V-shaped aerials, or by a single dipole mounted on a universal joint. A " mobile " unit, Fig. 6 (not shown), comprising a combined transmitter and receiver may be used for controlling gun-fire on a distant aeroplane or other reflecting body. Specifications 478,456; and 483,437, [Group XL], are referred to.

Title: Improvements in or relating to high frequency electron discharge apparatus
IPC: H03B21/02
Filed: 1944-07-04
Abstract: 606,109. Frequency measurements. SPERRY GYROSCOPE CO., Inc. July 4, 1944, No. 12763. Convention date, July 30, 1943. [Class 37] [Also in Groups XL (a) and XL (c)] In a circuit for producing an ultra-high frequency, an electron beam is velocity modulated at a first frequency and phase modulated by a second frequency, energy being extracted from the electron beam at a frequency different from the first frequency. The ratio of the first and second frequencies is arranged to be a rational number. The output of a crystal controlled oscillator 52 is converted to a highfrequency by a valve multiplier stage 54 and applied to a resonator 35. The electron beam from cathode 38 velocity modulated in passing through the first two grids associated with cavity 35, passes through the drift space 37 to a second resonant cavity 36 tuned to a harmonic of the frequency fed to the cavity 35. The output from the crystal oscillator 52 is also multiplied eight times by the valve multiplier 74, and applied to the cathode 38 with the result that sidebands appear in the output from the resonant cavity 36 spaced apart at the modulation frequency. By deriving the high frequency supplied to cavity 35 and the modulating frequency applied to cathode 38, from the same source 52 the sideband frequencies of one harmonic coincide with the sideband frequencies of the next harmonic. The sleeve 40 increases the capacity across the resonant cavity 35 thereby limiting its size. The tuning of cavity 36 is effected by screws 43 which distort the resonator. The screws may be calibrated to indicate the frequency at which the resonant cavity 36 is operating. For determining accurately the frequency of an unknown source, a rough check is first made with a wavemeter, the apparatus then being tuned by screws 43 to the nearest frequency as given by the wavemeter. The output from cavity 36 and the unknown source are fed to a crystal rectifier instrument which indicates the difference between the two frequencies. Specifications 523,712, 530,869, 531,067, [all in Group XL], and 8372/41, as open to inspection under Sect. 91, are referred to.

Title: Improvements in or relating to printing machines
Inventor: BENNETT ALBERT EDWARD
Filed: 1949-05-14
Abstract: 669,769. Printing. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 12, 1950 [May 14, 1949], No. 12918/49. Class 100 (iv). A printing machine comprises a continuously rotating type-wheel 4 and a hammer head 17 a frame 14 pivotally urged by a spring so that when an electromagnet 13 is operated the frame 14 is released from an armature detent 12 to make a partial movement towards the typewheel, means including a mechanical coupling with. the typewheel allowing a second rapid and accurately-synchronised movement of the frame towards the wheel so as to cause the hammer head 17 resiliently mounted by a spring 19 to the frame 14 to strike a type head on the wheel by means of its own inertia. Upon release of the detent 12 the frame 14 first makes a small movement until it is arrested by a projection 21 engaging the outer-surface 7 of a star-wheel 5 rotatively fixed to the type-wheel 4; upon continued rotation of star-wheel 5 the projection drops into the following tooth space in the wheel and the frame makes a rapid movement towards the type-wheel 4. This movement is adjustable by a screw 22 so that the frame is arrested when the head 17 is just clear of the type-wheel 4, whereupon the head by means of its inertia and the resilient connection 19 effects printing and springs back clear of the wheel 4. Continued rotation of the star-wheel causes the projection 21 to ride up the next tooth restoring the frame behind the detent 12. The return movement of the projection 21 may operate a link coupled to a pair of knurled strip feeding rollers and also operate an ink-ribbon advancing mechanism. Magnets 13 are operated at selected moments of the rotation of the type-wheel 4 by electrical arrangements operated through a commutator coaxial with the shaft 2 of the type-wheel.

Title: An hydraulic indexing device
Inventor: PHILLIPS REGINALD ARTHUR
IPC: F15B11/12
Filed: 1960-04-08
Abstract: 888,702. Knitting-machines. ELECTROHYDRAULICS Ltd. April 8, 1960 [April 16, 1959], No. 13021/59. Class 74 (2). [Also in Group XXIV] The hydraulically-operated output member 27 in an hydraulic system, for example, for shogging the guide-bars of a warp knitting machine, is locked in any one of a number of positions by a plunger 35 engaging between the ratchet teeth 28 cut in the member 27. When it is desired to vary the position of the output member 27 a solenoid-operated valve 10 is closed to prevent the flow of liquid from a pump 3 to the lower end of a chamber 33 by which a piston 34 coupled to the plunger 35 is normally urged to cause the plunger to engage the teeth 28. Simultaneously the valve 10 connects the chamber 33 to a reservoir 1 so that as liquid is pumped through a control valve 12 at half the normal pressure into chamber 29, enclosing the chamber 33 and plunger 35, the plunger 35 is moved away from the teeth 28 and the liquid in the lower end of chamber 33 forced into the line leading to the reservoir 1. A connection 40 extends between the upper end of chamber 33 and part of the bore 25 extending between the output member 27 and an input member 24, which are accommodated in the bore, so that as the plunger 35 is disengaged from the ratchet teeth a flange 41 on the plunger engages in the upper end of chamber 33 and isolates the liquid between the input and output members 24, 27. Movement of the input member 24, therefore, in one direction, causes the corresponding movement of the output member against the pressure exerted on its other end by the pressure of the liquid in chamber 29, and in the other direction permits the pressure liquid in chamber 29 to move the output member in the same direction as the input member. After the output member has been moved the desired amount the valve 10 is operated to cause the pawl to re-engage the teeth 28 to lock the output member in position and to permit the fluid in bore 25 to communicate with that in chamber 29 whereby the liquid pressure at each end of the output member is equalized. In an alternative arrangement the output member is coupled through linkage to the input member, a toothed quadrant forming part of the linkage which is partly rotated on actuation of the output member by the input member and which is locked in any one of a number of positions by a pawl which is hydraulically operated under control of valves in the system controlling the input member. In both arrangements the input member may be controlled by mechanism, which may be hydraulic, to move the output member a unit of movement or a multiple of such movement. Specification 888,701 is referred to.
