Title: Improvements relating to stacking apparatus
Inventor: WORSWICK ALAN
IPC: B22D5/00
Filed: 1968-01-30
Abstract: 1,254,871. Stacking apparatus; conveying and transferring ingots; grippers. A. WORSWICK 28 April, 1969 [30 Jan., 1968], No. 4688/68. Headings B8A, B8C and B8H. Apparatus for stacking articles, such as metal ingots into multi-layer stacks, comprises a conveyer 2 for delivering articles successively past a detector 3 for rejecting wrongly placed, or oversized, articles, a counting unit 2, a pair of jaws 19 for turning over the articles when required by a programmed sequence, a layer forming unit 5 which accumulates the required number of articles to form a layer, a stacker unit 6 having a grab 7 for lifting a layer of articles from the unit 5 and depositing it in an appropriate position on a stack support, means 8 for displacing a completed stack to further, conveying means 9, and a programmed control, Fig. 9 (not shown), for initiating the required movement. As shown, when an ingot runs down rollers 1 mounted on a tiltable frame 10 and reaches a stop-plate 11, the frame 10 is lowered to centre the ingot above the beams 12 of the walking conveyer 2 which is reciprocated by a pneumatic cylinder C, acting through a rack (36) and link 48, the rack 36 also operating, through a ratchet (40), a lift cam (44) and follower 45, a rod 46, and bellcrank levers 47, the conveyer beams 12 to lift them as they move forward towards the ejector device. An arm 16 of the latter operates an ejector cylinder C5 through a valve 29. A pusher 17 is movable by an arm 18 controlled by a cylinder C2 to move the ingot past a counting arm 21 to the turnover device 4 which includes the jaws 19 which are intermittently rotated by a belt device 20 to turn the ingots over, the belt of the device 20 being driven when a sprocket (43), Fig. 5 (not shown), is moved from a fixed position (42) and coupled with a drive dog (39) on the shaft (38) by means of a cylinder (C6). The ingots are then pushed onwards by the pusher 17, to lie side-by-side on the accumulator section 5. The stacker, Fig. 7, comprises a support column 23 in which is rotatably mounted a radial arm 24 for oscillating horizontal movement through an arc of 90 degrees by a cylinder C13, the arm 24 carrying a column 25, which can be raised and lowered by a cylinder 10 and which carries a grab 7 having two grab arms 29 pivoted to a bridge 30 and actuated by cylinders C8, C9. Alternate layers are deposited from the accumulator section 5 on to the walking conveyer 8 at right-angles to the preceding layer, a sprocket 26, rotatably mounted on the upper end of the column 23 and connected, by a chain 27, to a sprocket 26 on the column 25, beinglockable to the column 23 or the arm 24, respectively, by plungers 53, or 54 operable by pneumatic cylinders. The completed stacks are conveyed by the conveyer 8 to a storage conveyer 9 which is chair-driven by an electric motor. The movements of the apparatus are regulated by a controller (51), Figs. 8, 9 (not shown), to correspond-with the sequence of stacking operations.

Title: Improvements in or relating to magnetic induction accelerators
IPC: H05H11/00
Filed: 1947-02-18
Abstract: 659,804. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 18, 1947, No. 4737. Convention date, July 13, 1945. Addition to 645,939. Drawings to Specification. [Class 39 (i)] The betatron of the parent Specification is modified by replacing the radial auxiliary electrostatic field superimposed on the normal magnetic guiding field to produce the spiral path along which the electrons are introduced into the equilibrium circle by a magnetic auxiliary field. The auxiliary magnetic field is switched rapidly on and off, and is produced by an auxiliary winding consisting of two series opposing parts, one inside and one outside the magnetic guiding field poles. It is built up during times when the electrons are not being accelerated, and caused to die away rapidly on the introduction of the electrons. The auxiliary winding may also be employed for deviating the electrons from the equilibrium circle after acceleration. The batatron 1: 2 relation may be obtained by utilizing a counter-magnetization winding embracing only the induction field. This winding and the main excitation winding may carry the current for producing the radial auxiliary field. This current may in a modification, be carried by a D.C. winding provided for biassing the guiding field. A.C. voltages induced in the D.C. winding may be compensated by means of a transformer or by connecting the D.C. windings of two similar betatrons in series. Electrical or magnetic stabilizing lenses may be provided along the electron orbit.

Title: Improvements in or relating to sawtooth current circuit arrangements
IPC: H04N3/185
Filed: 1959-02-13
Abstract: 915,554. Cathode-ray tube circuits; sawtooth generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 13, 1959 [Feb. 15, 1958], No. 5077/59. Classes 40 (6) and 40 (7). [Also in Group XXXV] In a cathode-ray tube circuit variation in picture dimensions due to variation in deflection coil current is counteracted by varying the tube's final anode voltage, and vice versa. An analysis given in the Specification shows that the percentage change in coil current should be equal to half the percentage change in anode voltage and indicates the relationship between the circuit impedances that should exist if this criterion is to be maintained. In a first embodiment, Fig. 1, saw-tooth waves in the primary of a transformer 8 give deflection current in the coil 10 and pulses in the secondary are rectified to give the direct final anode voltage. Changes in deflection current are fed to a control circuit 13 which includes a non-linear resistance 14 across which is developed a potential which is fed to the grid of valve 1. A second embodiment, Fig. 4, ensures that if the anode voltage varies the deflection current varies in response. With this circuit the voltage developed across capacitor 7 may be used for feeding the deflection circuit of the coil perpendicular to coil 10. A development of Fig. 4, Fig. 5 (not shown), comprises an amplifying valve which is biased from a non- linear element and which is fed with pulses from a tapping on the transformer primary.

Title: Revolving barrel locks
IPC: E05B9/08
Filed: 1921-02-16
Abstract: 181,429. Best, F. E., and Best Lock Co. Feb. 16, 1921. Locks, revolving-barrel.-A pin-tumbler lock has its pins formed in three sections, so that upon the insertion of one key one set of breaks is lined up to permit rotation of the barrel to operate the lock-bolt, but insertion of another key lines up the other breaks so that a core carrying the whole mechanism can be withdrawn from the case intact. Fig. 1 shows the position when a key 21 has been inserted to line up the lowest sections of the pins 12 with the edge of the barrel 6, which can then be rotated to move the member 7 by which the bolt is operated in the normal manner. A second key 22, Fig. 4, is so formed as to align the second sections of the pins with the division 27 between an extension 4 on a sleeve 3 embracing the barrel 6 and a cone 2 enclosing the top sections of the pins and controlling-springs 16. In this position, the part 4 can be turned sufficiently, as shown in Fig. 4, to disengage teeth 10 thereon from inter-engaging parts 11 on the outer casing. The whole core and locking- mechanism, Fig. 7, can then be withdrawn. Curved parts 5 on the core 2 project through apertures in the part 4 and hold the two pieces together, the surface of separation 27 being shaped somewhat eccentrically so as to prevent relative movement to a degree sufficient to disturb the internal mechanism. The releasing movement of the core to the position shown in Fig. 4 causes slots upon the part 4 to engage over projecting flanges 19 of a capping-piece 15, to which is secured the bearing studs 17 and springs 16 for the pins 12, the whole of which capping-piece can be removed bodily to give access to the pins when the core has been withdrawn and the part 4 moved relatively thereto to align the pins as shown in Fig. 2. The part 7 by which the bolt is operated engages in a recess across the end of the barrel and behind a shoulder 8 on the sleeve part 3, and can only be removed by turning the barrel relatively to the sleeve far enough to clear the end 9 of the shoulder. The main casing 1 screws into its fixing-plate 23, and is locked by a pin inserted in aligned grooves in both parts and bent inwardly adjacent the front plate 2 of the core whereby it can only be removed when the core is withdrawn from the sleeve.

Title: Improvements in or relating to glass fiber optical devices
IPC: H01J29/89
Filed: 1966-02-08
Abstract: <PICT:1083513/C1/1> A method of hermetically sealing undesirable interstices in a bundle of glass clad glass fibres, all fused together in side-by-side substantially parallel relationship with each other. comprises the steps of constraining the bundle against appreciable volumetric expansion when the fibres are heated, heating the constrained bundle sufficiently to develop a hydrostatic pressure in the bundle of such force as to close said interstices.  A bundle of glass fibres 10, such as those used in fibre optic devices and cathode-ray tube face plates, is machined to just fit within a cavity 24 of a constraining device 16 made of a material having a substantially lower coefficient of expansion than the glass bundle, e.g. tungsten or molybdenum. The unit is heated to above the softening points of the glasses by gas burners or electrical means 28 at which temperature and due to the differences between the expansion coefficients of the bundle 10 and device 16 a hydrostatic force is set up which causes any gases between individual fibres to be either dissolved or absorbed in the glasses or to be broken up into minute bubbles.  The unit is then cooled to room temperature. Alternatively, where there is not a substantial difference between the coefficients of expansion of a bundle (110), and constraining device (118), the bundle may be held in a steel jacket (126) having a similar expansion coefficient as the glasses and between the jacket (126) and device (118) are placed spacers (124) having an expansion coefficient substantially higher than either bundle (110) or device (118), e.g. stainless steel.

IPC: E05B65/08
Filed: 1922-02-24
Abstract: 190,392. Redmond, J., and Redmond, J. Feb. 24, 1922. Sliding bolts; door chains and the like.-In a fastener for sliding, hinged, and pivoted windows and doors which can only be released from the inside when the windows or doors are closed and enables the. window or door to be partially opened for ventilation, a headed bolt with side wings cooperates with a rack having a longitudinal slot with transverse side notches. The Figures show the device applied to sliding windows. The bolt 17 is square and fits into a squared part of the casing 13. The squared part 17 ends in a disclike head 16 behind which are a pair of ear-pieces 18. A sleeve 15 is rotatably mounted on the bolt and has a slot 19 with side recesses 20, 21, which co-operate with a pin 22 on the casing to hold the bolt in its shot or withdrawn position. The sleeve 15 is turned by a knob to bring the pin 22 into the slot 19 and the bolt is pushed in so that the head 16 of the bolt enters the circular hole 9 in the rack-plate 6. The engagement of the ears 18 with the sides of the hole 9 prevent the window sashes from being moved apart for opening. If the bolt is pushed in a little further, an extension of the slot 19 allowing of this, the ears 18 clear the plate 6 and the sashes can be parted, the bolt shank 17 moving up the slot 10 in the rack plate 6. By pulling back the bolt until the ears 18 engage pairs of recesses 11 in the slot 10 of the rack-plate and turning the sleeve 15 to engage the notch 21 with the pin 22, the sashes can be locked in the partially-open position, and cannot be unlocked for complete opening until first closed to bring the head 16 opposite the hole 9 in the rack-plate.

Abstract: 649,919. Clamps. FAIREY AVIATION CO., Ltd., and SMITH, G. C. Feb. 24, 1948, No. 5486. [Class 44] A rope cleat suitable for securing the jib sheet 13, Fig. 5, in a dinghy, comprises a base having an operative surface 25, and a pivoted wedge 22 mounted in bearings integral with or secured to the base and rotatable in either direction about an axis parallel with the surface 25, the wedge being symmetrical about a median line passing through and normal to its axis of rotation and so spaced therefrom that the rope 13 is gripped between the surface 25 and the wedge 22 before the greatest radius of the wedge is normal to the surface 25. The wedge is rotated by means of a crank handle 26 extending radially from the axis on the opposite side to the wedge and of substantially the same length as the latter. Upstanding lugs 20, Fig. 3, rigid with the base 18, carry a spindle 21 on which the wedge 22 and handle 26 are mounted. The wedge 22 has an arcuate shaped lower face 23 formed with gripping serrations 24. With the wedge as in Fig. 5, a pull by the rope 13 to starboard causes it to be gripped. To enable the cleat to resist a pull to port, the handle 26 is rotated clockwise, normally by foot, to bring the wedge to a corresponding position on the starboard side of vertical. A pair of rollers 28 mounted on spindles 27 constitute fairleads. In a modification, a tube 29, Fig. 7, lying between the lugs 20 has belled ends 30 to constitute fairleads. The upper central portion 31 of the tube 29 is cut away to allow free rotation of the wedge 22. A remote control may be provided in the form of a linkage connected with the operating lever, or a. gear-driven spindle in association with the spindle 21 and a locking pin may retain the wedge against movement.
