Title: Improvements relating to optical apparatus
Inventor: DYSON JAMES
IPC: G01B11/27
Filed: 1959-01-29
Abstract: 895,564. Optical aligning apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1960 [Jan. 29, 1959], No. 3262/59. Class 97(1). Optical apparatus for indicating the displacements of a body from a vertical straight line comprises an optically transparent flat plate extending substantially horizontally, a circular diffraction grating formed on one surface of said plate, a horizontal reflecting surface located on one side of said plate, a holder adapted to be attached to said body and to contain a point source of light which is located on the opposite side of said plate so as to project a beam of light in a direction which is substantially normal to said reflecting surface, in such a manner as to produce a line image of said source extending on the opposite side of said plate from the centre point of said diffraction grating and displaced from the vertical reference line through said centre point symmetrically with the line joining the point source to said centre point, together with means for indicating the position of said line image so as to indicate displacements of said holder and said body from said vertical reference line. As shown, the apparatus comprises a holder A attached to a body B, the displacement of which from a vertical straight line is to be measured. The holder A contains a point source of light S and cross wires W both mounted on a rod T operable by a micrometer screw M. The light from the source S falls on diffraction grating G close below which is a reflecting surface formed by a pool of mercury R, so that a line image of the source extends from the centre point C of the grating to a position I disposed symmetrically on the opposite side of a vertical reference line defined by the line through the centre of the grating C. In use the rod T is moved until the cross wires W appear to coincide with the line image at I when viewed through a lens L. By viewing the image I continuously, displacements of the cross wires W from this image will indicate displacement of the box A and body B from the vertical reference line, and such deviations can be measured by the micrometer M. Reference has been directed by the Comptroller to Specification 862,290.

Title: Improvements in and relating to punching machines
Filed: 1927-02-04
Abstract: 285,243. Thomas, A., and Accounting & Tabulating Corporation of Great Britain, Ltd. Feb. 4, 1927. Cards, punching.-In a machine for duplicating jacquard-cards, sensing-pins that have passed through a perforation in a master-card are locked for punching a blank-card by pins that have not passed through the card. The master-cards are fed by a picker C from a hopper A through rolls G, a pin-box and rolls U to a bin V. The blanks are fed by similar mechanism to a bin Y. An eccentric 0 reciprocates the pin-box through a direct link and the punch-box through togglelinks S, Q. The position of the connection of the link Q to the punch-box is such that the latter reciprocates half the distance of the pin-box. On depression of the pin-box, sensing-pins 1 that do not find holes are raised together with coaxial set-bars 4. Inclines 20 on the latter move locking- bars 22 to the right, and projections 23 thereon hold the effective set-bars which, through rods 26, gag the punches. The parts are restored on the upstroke of the pin-box when the projections 23 enter recesses 17. Locking pawls may be fitted to the bars 23 to hold a group of pins inoperative.

Title: A binary circuit or scaler
IPC: H03K3/315
Filed: 1961-01-27
Abstract: 929,525. Tunnel-diode bi-stable circuits. SONY CORPORATION. Jan. 27, 1961 [Feb. 10, 1960], No. 3323/61. Class 40 (6). A binary counter comprises a tunnel diode D connected in series with resistors 3, 4 between a positive-supply terminal 5 and earth, the values of the resistors and the power supply being such that the diode may assume either of two stable states, a source S of positive pulses, and a steering circuit comprising rectifying diodes 9, 10 connected respectively between the source S and opposite terminals of the diode D and respective biasing resistors 13, 15 for the diodes 9, 10 connected to potential sources of such values that, in one condition of the diode D, pulses from source S are passed by the diode 9 to switch the diode D to its other condition, while, in the other condition, pulses from the source S are passed by diode 10 to switch the diode D back to its first condition. Supply terminal 14 is made slightly negative with respect to the lesser of the two voltages which may appear at the point P, this occurring when the diode D is in its state of high conduction, while supply terminal 16 is made slightly negative with respect to the lesser of the two voltages which may appear at the point Q, this occurring when the diode D is in its state of low conduction. If the diode D is in its highconduction state, a positive pulse from source S will cause diode 9 to conduct and by increasing the current momentarily through the diode D will switch it to its low-conduction state. A subsequent pulse from source S will now cause diode 10 to conduct, reduce the current through the diode D and switch it to its high-conduction state.

Title: Fuse  for detonating the explosive charge of a missile
IPC: F42C15/24
Filed: 1974-01-24
Abstract: 1463112 Projectile fuses FORENADE FABRIKSVERKEN 24 Jan 1976 [31 Jan 1973] 3387/74 Heading F3A An instantaneous or delayed action projectile fuze, comprises: priming charges 11a and 11d, Fig. 1; a delay charge 11b; and a striker 7a which penetrates only the charge 11a if the delay charge 11b is to be ignited, but which strikes through the charges 11a, 11b and into the charge 11d for instantaneous action. In the embodiment according to Fig. 1, instantaneous action is effected by an electrical signal from a proximity fuse 6 detonating an explosive charge within a housing 7, whereby the striker 7a is driven through charges 11a, 11b and into the charge 11d. Prior to firing the projectile, the electrical igniting means for the explosive charge is short circuited by an inertia bolt 12 touching a contact 8. Upon acceleration of the projectile, the bolt 12 sets back to break the short circuit and to release a blocking safety element 17 which swings outwardly owing to centrifugal force. For delayed action, the electrical firing means for the explosive charge is permanently short circuited by means not shown and the priming charge 1la is detonated when the holder 11 is thrown towards the stationary striker 7a. In another embodiment, Fig. 4, a spring biased striker 19 is locked at safe by a ball 20 until a sleeve 21 sets back upon axial acceleration of the projectile. For delayed detonation, an element 24 engages a shoulder 26 of the striker to limit its displacement. However, for instantaneous action, a knob 22 is rotated so that the element 24 is free to move outwardly from its blocking position owing to centrifugal force. In another embodiment, Fig. 5, a centrifugal locking element 24<SP>1</SP> moves outwardly on firing a missile fitted with the fuze and delayed detonation occurs on impact with a target owing to the throwing forward of the cartridge 27<SP>1</SP> against the locked striker 19<SP>1</SP>. For instantaneous detonation, the knob 22<SP>1</SP> is rotated so as to free the ball 25<SP>1</SP>, thereby to allow a sleeve 21<SP>1</SP> to set back at launch and free a ball 20<SP>1</SP>, whereupon the striker is driven by a spring through the first priming charge and the delay element into igniting contact with the instantaneous priming charge.

Title: Improvements relating to liquid fuel supply systems
IPC: F02C7/22
Filed: 1946-02-04
Abstract: 607,189. Liquid-fuel burners. LUCAS. Ltd., J.. and IFIELD, R. J. Feb. 4, 1946. No. 3426. [Class 75(i)] [Also in Groups XXVI and XXIX] In a system for supplying liquid fuel to the swirl chamber c of a nozzle in the combustion chamber of a furnace in which excess fuel returns from the swirl chamber to the main delivery pipe d along a separate pipe g forming. with the main delivery pipe, a local circuit for excess fuel, the system comprises a main variable delivery pump a, an auxiliary pump h in the local circuit for returning the excess liquid, means such as an orifice i for creating a pressure difference, and means responsive to such pressure difference for regulating automatically the output of the main pump. Pump h is shown as a variable delivery swash-plate pump of which the output is under the control of a manual lever y, but it may be replaced by a fixed delivery pump, in which case the orifice i should be adjustable. The pressure difference created across orifice i is applied to the two sides of a spring-loaded diaphragm n, and the latter controls a hinged valve o which vents fluid from one side of a spring-loaded servo-piston p controlling the swash-plate of pump a. The output pressure from pump a is applied to both sides of piston p and the two sides are interconnected by a restriction x. By a suitable arrangement of pipes and valves, pump h could be connected for use as the main pump in the event of failure of pump a. Specification 577,016, [Group XXIX], is referred to.

Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M7/20
Filed: 1938-02-04
Abstract: 496,983. Spray carburetters. SOC. ANON. SOLEX. Feb. 4, 1938, No. 3590. Convention date, Feb. 12, 1937. [Class 7 (iii)] The fuel supply is controlled by a single barometric or manometric device operated either by the pressure on the engine side of the carburetter throttle when the engine is running near its maximum power or by the pressure on the air inlet side upon a fall in the density of the air. A barometric or manometric capsule 16 in a chamber 17 controls a needle valve 6 regulating the fuel supply to a nozzle 9. The chamber 17 is in constant communication with the intake conduit on the engine side of the throttle 12 through a passage 19 containing a calibrated orifice 20, and as the engine speed increases the capsule increases the fuel supply. As the speed falls the capsule reduces the fuel supply until a passage 23 in the valve stem 15 registers with a channel 22 to establish communication between the chamber 17 and the intake conduit on the air inlet side of the throttle. The air is preferably supplied by a compressor 24, the inlet valve 25 of which is opened, as the density of the air falls, by a servomotor 27 controlled by a capsule 32 subject to the pressure in the outlet of the compressor. When the valve 25 has been fully opened, any further decrease in the density of the air is transmitted to the chamber 17 and reduces the fuel supply.

Title: Improvements in the heat sealing and severing of materials
IPC: B29C65/14
Filed: 1964-01-28
Abstract: 1,027,528. Flat plastics bags. E. KUGLER. Jan. 28, 1964, No. 3603/64. Heading B8K. [Also in Divisions B4 and B5] A process for heat sealing and/or severing a preselected zone 20, 21 or 22 of a thermal treatable material 10 comprises printing on the preselected zone 20, 21 or 22 a layer of a thermal emitting responsive compound 18 and exposing the compound 18 to a discrete environmental condition whereby the compound 18 will respond by emitting a predetermined quantity of thermal energy. Bags 71, open at one end, are produced from a continuously advancing web 10 of heat sealable material, e.g. polyethylene, having a longitudinal fold 11 forming overlying walls 13, 14. Advertising matter may be printed on one or both walls 13, 14. The web 10 is passed over a backing roller 15 to contact an impression printing roller 16 immersed in a bath of ink compound 18 which must be electrically conductive, e.g. saturated with a relatively fine silver powder. The roller 16 prints a series of curved lines 20, a continuous line 21 parallel to the fold 11 and small circular areas 22. At station A, freely rotatable rollers 30, 31 press the walls 13, 14 into contact and a magnetic field is generated by an induction coil 40 connected to a high frequency oscillator 41 through a control 42. The magnetic field causes eddy currents to be induced in the line 21 and by adjustment of the control 42 sufficient thermal energy is released in the line 21 to bond the walls 13, 14 to form a seal line 23. At stations B and C, by adjustment of controls 52 and 62, respectively, induction coils 50, 60 cause eddy currents to be generated in the areas 22 and lines 20 to form circular cut-outs 25 in the wall 14 only and side seals 26, 27. The bags 71 are removed by a conveyer 70. In a modification, the ink contains silver azide and the elements 40, 50, 60 each represent source of ultra-violet light and/or gamma rays which cause the silver azide to disintegrate and release thermal energy. In a further modification, the ink is relatively dark, preferably black. The elements 40, 50, 60 each comprise a high intensity source of monochromatic light absorbed by the dark areas which generate thermal energy.

Title: Improvement in label applying mechanism
IPC: B65C1/02
Filed: 1926-02-09
Abstract: 270,018. Marks, E. C. R., (Package Machinery Co.). Feb. 9, 1926. Labelling. - A labelling-machine, preferably for use as an attachment to a machine for performing some other operation, such as wrapping, comprises an oscillating label and transferring and affixing device which seizes the label at the end of the supply strip and transfers it to a position above the article to be labelled, an oscillating knife for severing the label from the supply strip, and an adhesive applying device for coating the severed label during transfer. The label transferring and affixing device 50 comprises a flat affixing plate 58 and a movable finger 60, both mounted on an arm 62 which is pivotally connected to a vertically oscillating carrier 66. The carrier 66 oscillates on a sleeve 68 secured to the frame, a crank pin 74 on a disc 76 secured to the main shaft extending loosely through a slide block 80 which reciprocates in a guideway 82 in the carrier. The main shaft is adapted to be driven from the wrapping &c. machine. The movement of the arm 62 is controlled, through a cam roll 90, by a cam 88 fixed on the frame, so that when the carrier 66 is at the upper limit of its movement, the finger 60 and the plate 58 are positioned to grip the label strip projecting from a holding device 30. The knife 52 is actuated to sever the roll on the downward movement of the carrier, being swung upwardly by a cam face 144 on the disc 76 engaging a cam roll 140 on the arm carrying the knife, just before a row of projections in the label strip pass the knife 52 which is formed with a serrated cutting-edge. The plate 58 is then moved by the cam 88 to pass the label over a glue roll 54, the label finally contacting at right-angles with the article. The plate 58 is adjustable on the arm 62 by a screw 98, and bolt 102. The finger 60 is carried by an arm 106 pivoted on the arm 62, the arm 106 being also pivoted to a link 110 which is pivoted to an elbow lever 112 pivotally carried on the arm 62, the link 110 and lever 112 being arranged as a toggle. The open position of the finger 60 is determined by the engagement of the link 110 with a stop 118 on the arm 62, engagement with a similar stop maintaining the finger 60 closed. The lever 112 is actuated by curved arms 128, 130 on a rocker 72. As the label applying device 50 reaches the limit of upward travel, a cam 126 rocks the lever 112 downwardly so that the link 110 engages the lower stop to close the finger 60, which then grips the label strip. As the device 50 reaches its lower limit, the shaft 120 is rocked by the cam 126 so that the rocker arm 130 swings the lever 112 upwardly to bring the link 110 against the stop 118 to open the finger 60 and release the label which is then pressed on to the package. Specification 269,246, [Class 94 (i), Packing &c.], is referred to.
