Abstract: 755,121. Starting and stopping oil engines. C.A.V., Ltd. Feb. 4, 1955 [Feb. 18, 1954], No. 4759/54. Classes 7(3) and 7(5) Extra fuel control means for a fuel injection pump permitting the supply of excess fuel at starting comprises a manually operated slidable rod c with a collar h secured thereto and a spring-loaded frusto-conical stop collar i slidable thereon, the collar i normally being positioned in the path of an abutment m extending from the pump control rod a to limit the normal maximum fuel supply but being movable sideways out of the path of the abutment m to permit the excess fuel supply. For starting the rod c is pushed inwards and the collar h thereon moves the collar i out of the path of the abutment m which moves inwards behind the rear face of the stop i to contact the collar h. The rod c is then pulled outwards to move the collar h back to its normal position, permitting the abutment m and rod a to move further inwards to the excess supply position; the stop i being held in its displaced position by the abutment m engaging therebehind. When the engine starts, the abutment m and rod a are withdrawn by the engine governor, releasing the stop i which is returned to its normal position by the spring j. The normal maximum supply is adjusted by adjustment of a bush n which moves the collar h and hence the stop i relative to abut. ment m. In a modification, Fig. 3, the rod c in addition to being slidable, is rotatable to cause an arm o on the collar h to engage an arm p to move the control rod a to the fuel cut-off position for stopping the engine.

Title: Improvements in or relating to colour cathode ray image display systems
IPC: H01J29/46
Filed: 1960-02-12
Abstract: 947,916. Colour television tubes. GENERAL ELECTRIC CO. Feb. 12, 1960 [Feb. 16, 1959], No. 5028/60. Heading H1D. In a colour television or radar display tube in which coaxial electron beams of differing velocities, e.g. 10 KV and 20 KV are deflected in unison over a superimposed phosphor layer viewing screen into which the beams penetrate to different extents dependent on their velocities to excite the various colours, the divergence of the beams due to their differing velocities is compensated by deflection in the opposite direction to restore coincidence of the beams at the screen. .As shown, where a first beam 30 produced by gun system 7 passes through a second gun system 8 which produces the second beam 42, the main deflection is produced by magnetic coils 14 and the counter-deflection is produced by coaxial cylinder lens system 16, 46. Cylinder 16 may be positive or negative with respect to cylinder 46. The cylinder 16 is slotted to reduc eddy currents. Each gun system has a control electrode 9, 11 and associated with it a beam centring magnetic device 31, 47 composed of a pair of separately rotatable, diametrically magnetized, annular magnetic plates. The cathode 38 of the second gun system is annular and the final anode 46 is connected to the wall coating 51 by a spring member 52 and a metal collar 53. In another embodiment the converging lens system 16, 46 is replaced by an electrostatic plate deflection system in which the deflection voltages are synchronized with the currents applied to the magnetic deflection coils. The second beam 42 may intermingle with the first beam 30 or may be an annular beam surrounding the first beam. In another modification referred to an electrostatic deflection system with a timevarying voltage is associated with an electromagnetic deflection system supplied with a time-independent current.

Title: Improvements in or relating to typographical composing and slug casting machines
IPC: B41B11/38
Filed: 1940-03-18
Abstract: 539,591 Type-bar-making machines. MERGENTHALER LINOTYPE CO. March 18, 1940, No. 5042. Convention date, April 1, 1939. [Class 100 (iii)] Justifying and clamping matrices. Wedge spacebands are formed in two separate sections the shorter of such sections being of similar form to the matrices and being adapted to circulate with them through the machine, and the longer sections being stored permanently at the line-justification station. The short sections 15, Fig. 13, are provided with distributing-teeth 29, and have at their lower ends extensions 31 adapted to co-operate with the upper ends of the long sections. The front lower ears 28b of the short sections are at a higher level than the rear ears 28a, so that the sections are always assembled at the lower level regardless of the position of the duplex rail. The long sections each comprise a tapered upper member 35, Fig. 14, and a rectangular lower member 36, which are connected together by a spring plate 37. The tapered member carries a pivoted lifting- dog 38, and the lower member has a spring- pressed lifting-pin 41 projecting from it. The long sections are stacked in a box 32, Fig. 2, which is mounted in the vice-frame; so as to be directly below the composed line when it is in the casting position. The sections are supported in the box by a cross-plate passing through slots 46 in the lower members. When the first elevator is arrested in the casting position, the upper ends of the long sections are slightly above the lower ends of the extensions 31 on the short sections. Automatic means are provided for adjusting the box 32 vertically in accordance with the two different levels at which the elevator may be arrested. The box is moved laterally by a cam 70 on one of the justification-rods, so as to bring the upper ends of selected ones of the long sections into contact with the extentions 31 of the short sections. As the justification-bar 42 rises, it raises the long sections by their lifting-pins 41, so that those which are in contact with short sections are carried up into the line, the rest being arrested by contact with the matrices or with the vicejaws. The upper ends of the long sections are guided between the facially projecting ears 28a, 28b on the short sections. The resistance of the line causes the spring pins 41 to be forced inwards, and the justification-bar then engages the lifting-dogs 38 and expands the line. On the descent of the justification-bar, the long sections are pulled down by means of their lifting-pins. To prevent any looseness of the line before justification, which would allow unintended long sections to pass between the matrices, a spring 90 is introduced between the left-hand jaw 25 and its jaw-block 91.

Patent GB-151206-A (GB)
Title: Improvements in electric circuit controllers
IPC: H02P1/18
Filed: 1920-02-20
Abstract: 151,206. Amberton, R. Feb. 20, 1920. Controllers, interlocking; with auxiliary switches.-In a controller with spring-connected handle and brush lever the initial forward movement of the handle turns a switch which makes a connexion between brushes in the actuating circuit of the main contactors; the release and backward movement of the handle serve to open the switch. The central pillar 2 supports the handle 4 and brush lever 3 which have dependent lugs with a spring 28 disposed between them. The contact plates and brushes may be of the type described in Specification 144,212. The brush engaging the contact segment 15 has its conducting-socket extended to engage spring-pressed levers 17, 18 at the limits of its travel. The pin 20 of this brush projects through the insulating- block 21 and forms a pivot for a switch lever 22 pressed into the position shown in Fig. 1 by a spring 23. This lever carries a plunger contact 26 to make contact with the pin 19, and also an insulating-block 25 to engage a similar block 24 on the handle lever. With the parts in the zero position, the contact socket engages the arm 17 and the initial movement of the handle closes the contacts 26; 19 without moving the brush lever 3. Current then flows through the lever 17, the economy switches 53, 54 and the coils 39, 40 to actuate the main contactors 35, 36 which then close the motor circuit through the blow-out coil 60, the sector 9, the brushes on the lever 3, the resistance 10, the motor armature 33, and the overload release coil 42. The closure of the contactors opens the economy switches 53, 54 to insert the resistances 41 in the actuating-circuit. The handle and brush lever are then moved forwards together to cut out resistance. During the movement, the release of the handle opens the contacts 26, 19 and thereby de-energizes the main contactors to break the motor circuit, but the engagement of the contact socket with the arm 18 at the end of the travel closes a maintaining- circuit in shunt across the contacts 26, 19 so that the motor runs continuously until the handle is pulled back. A push-button 45 may be used for starting and inching, and a button 46 for stopping. Specification 28527/13 is referred to.
