Title: Improvements in engine starting mechanism
IPC: F02N99/00
Filed: 1930-09-03
Abstract: 357,746. Turning-gear. E C L I P S E AVIATION CORPORATION, 545, North Arlington Avenue, East Orange, New Jersey, U.S.A. Sept, 3, 1930, No. 26333. Convention date, Sept. 6, 1929. [Classes 7 (ii) and 7 (v).] An engine starter comprises a jaw clutch 40 movable into engagement with an engine member 44, a flywheel 4 which is set in rotation by an electric motor or other means, and friction clutches 52, 33 by which the flywheel is coupled through a driving member to the jaw clutch 40 to enable the energy of the flywheel to be transmitted gradually to the engine. The torque-transmitting capacity of the clutch 52 is preferably greater than that of the clutch 33, so that the latter slips until the resistance to starting has been overcome. As shown in the Figure, the flywheel 4 is set in rotation by means of an electric motor 8, the shaft 11 of which carries a clutch member 9 movable automatically on helical splines 12 into and out of engagement with a member 10 carried by the hub 16 of the flywheel, the member 9 being normally disengaged by a spring 14. The flywheel is coupled to the driving pinion 22 by means of a cone clutch 52, the hub 53 of which is actuated by a yoke 55 on a rock-shaft 56a rocked by a lever 57. The hub 53 is helically splined on the shaft 20 of the pinion 22, so that the clutch 52 is rotated as it is moved into engagement with the flywheel. The pinion 22 meshes with planetary pinions 23 rotatable on the end 24 of a driving barrel 25 and meshing with a fixed internal gear 29. The barrel 25 is connected by the adjustable multiple-plate friction clutch 33 to a nut 32 in engagement with a threaded shaft 36, on which the jaw clutch 40 is longitudinally splined, an axial rod 43, nut 43a, and spring 42 maintaining the clutch 40 and shaft 36 in operative relation. When driven from the flywheel 4 through the clutch 52 and planetary &c. gearing, the clutch 40 is moved automatically into engagement with the engine member 44 by the action of the nut 32 and threaded shaft 36, longitudinal slots 48 in the periphery of the jaw clutch being engaged by lugs on a split ring 50 frictionally supported on the lip of a casing member 51. A flexible washer 51b carried by the member 51 engages the part 39 of the jaw clutch to exclude oil from the starter housing. In a modification, the driven member 44 of the jaw clutch is mounted on the shaft of a rotary supercharging blower driven from the engine shaft through two-step reduction gearing from an internally toothed gear on the engine shaft.

Title: Coin-guiding device in coin wrapping machine
IPC: G07D9/06
Filed: 1972-06-07
Abstract: 1323270 Machine for wrapping coins GLORY KOGYO KK 7 June 1972 [18 June 1971] 26516/72 Heading B8C A machine for wrapping successive stacks of coins introduced between wrapping rolls 13 and in which the wrapping material is folded over  the ends of the stack, includes a coin guiding  device comprising a guide mechanism 11 having a guide member 40 adapted to undergo horizontal and vertical movements and operating to receive and support the stack and to guide the stack between the rolls, positioning means for adjustably determining the elevational position of the guide member and an actuating mechanism for co-ordinately operating the guide mechanism and the positioning means. As shown, coins at the periphery of a turntable 1 are directed along a passage 3 by a conveyer belt 4 and are counted and stacked in a tube 6, which is normally closed by a gate mechanism 7, but which is opened by a cam 9 to allow the stack to drop on to the guide member 40 which lowers the stack to a position between the pair of rolls 13. The rolls are closed on to the stack and a length of wrapping paper 18 is then drawn between the rolls and around the stack to wrap the same. Fold forming hooks 16, 17 are then engaged with the upper and lower margins of the wrapper which is thereby tightly folded over the ends of the stack. The member 40 and the hooks 16, 17 disengage the wrapped stack which drops into a shoot 19. The mechanism 11 comprises a cam 21, Fig. 2, for actuating the guide member 40 and is driven from a cam-shaft 8. The cam 21 is provided with a peripheral cam surface and a side cam surface and is engaged with a pin 22 on a bar 23 which is pivoted at one end to a rotatable shaft 63 and at its other end to a guide bracket 27. A lower bar 24 is also pivotally connected with the shaft 63 and bracket 27, the arrangement being such that rotation of cam 21 causes horizontal and vertical movement of the bracket 27 about the shaft 63. The bracket 27 carries an electromagnet 29, a core 30 of which is connected through a rod 32 to a spring-loaded cam member 34, Fig. 3, a cam edge 36 of which operates on a pivoted lever 37 which supports the guide member 40. The arrangement is such that the guide member 40 can be raised by an appropriate amount in the case where very thin coins are stacked in order to bring the stack centrally of the width of the wrapping paper 18. An actuating lever 46 is engageable with a member 45 fixed to a sleeve 41 for the guide member 40, is pivoted at 47 to the shaft 63, and at lever 48 also pivoted at 47 to the shaft 63, engages an adjustable cam 54 through a roller 49 such that rotation of cam 54 causes pivoting movement of lever 46. In another arrangement, Fig. 4 (not showm), the sleeve 41 is dispensed with. In other arrangements, Figs. 5 and 6 (not shown), a modified connection between the magnet core 30 and the member 40 is described. In all arrangements, the wrapping operations are controlled by a motor driven cam-shaft 8.

Abstract: 836,403. Gas-blast switches; pneumatic action of switches; indicators for switches. ENGLISH ELECTRIC CO. Ltd. Sept. 14, 1956 [Sept. 20, 1955], No. 26843/55. Class 38 (5). In a switch-gear system comprising a plurality of gas-pressure-operated circuit-breakers 4 ... 6 arranged for simultaneous operation, an indicating arrangement is responsive to the individual pressures which operate each circuitbreaker, the indicating arrangement detecting when a time-lag between the instants of application of the pressures is longer than a predetermined period. In Fig. 1 air blasts are applied to the circuit-breakers 4 ... 6 through pipes 7 ... 9 which also supply pressure-operated micro-switches 10 ... 12. If pressure is not applied to the pipes at the same instant and the time-lag is sufficient, then one of the microswitches will have its movable contact in engagement with a fixed contact 10a, 11a or 12a, whilst another will have its movable contact in engagement with a fixed contact 10b, 11b or 12b so completing a circuit for a relay 14 which closes its contacts 18 to complete a circuit for an indicator 19. Auxiliary switches 15 . . . 17 open with the circuit-breakers to prevent incorrect operation of the indicator should there be a difference in the resetting times of the micro-switches when the application of the air-pressure ceases. The circuit-breakers may be provided with the pneumatic retaining and interlocking coupling of Specification 818,521, Fig. 2 (not shown), each micro-switch 37, Fig. 3b, being connected to the valve assembly of the associated circuit-breaker by means of connectors 45, 42. When a blast of air occurs in the valve assembly, air forced through the connectors acts on the central limb 49 of a trifurcated blade spring 46 and forces the blade spring to move from the position shown in which a moving contact carried by the spring 46 engages a fixed contact 48, into a position in which the moving contact engages a fixed contact 50.

Filed: 1966-06-16
Abstract: 1,147,468. Modified unsaturated polyesters and resins produced therefrom. HITACHI CHEMICAL CO. Ltd. 16 June, 1966 [25 June, 1965], No. 26891/66. Headings C3P and C3R. A modified unsaturated polyester is obtained by heating an unsaturated polyester having a hydroxyl number of from 10 to 450, which has been obtained by reaction of an alpha, betaunsaturated dibasic acid or acid anhydride and a polyhydric alcohol, with allyl alcohol and formaldehyde or paraformaldehyde, the amounts of allyl alcohol and formaldehyde being from 30 to 130% (equivalent) based on the number of hydroxyl groups in the polyester starting material. The reaction is preferably carried out in the presence of a catalyst e.g. H 2 SO 4 , FeCl 3  or CaCl 2 . The modified polyester may then be copolymerized with an unsaturated monomer such as styrene. A polyester prepared from maleic anhydride, diethylene glycol and glycerine is modified in Example 1 with allyl alcohol and paraformaldehyde, the resulting polyester is mixed with styrene, methyl ethyl ketone peroxide and cobalt naphthenate and the mixture is coated on a glass plate and cured. In Example 2, the polyester used is prepared from maleic anhydride, itaconic acid and propylene glycol and the modified polyester is copolymerized with styrene and methyl methacrylate using cumene hydroperoxide and benzoyl peroxide as catalysts. The unsaturated polyester in Example 3 is derived from fumaric acid and propylene glycol and the modified polyester is copolymerized with styrene, using the catalyst mixture of Example 2 and also cobalt naphthenate, on a stainless plate.

Title: Improvements in electrical oscillation generators
IPC: H03K4/26
Filed: 1948-10-16
Abstract: 655,102. Saw-tooth generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 16, 1948, No. 26936. Convention date, Oct. 17, 1947. [Class 40 (vi)] A saw-tooth wave is generated in the anode circuit of a valve by slowly charging a capacitor connected to the grid and rapidly discharging it through a unilateral conductive device con. nected to the secondary of a transformer, the primary of which is connected to an auxiliary electrode of the valve and which applies a voltage developed at the auxiliary electrode to the device to render it conductive. A capacitor 21 which carries a negative charge discharges substantially linearly through resistors 23 and 25 connecting to a +H.T. source with the result that the anode and screen currents rise to produce the long Hank of the saw-tooth wave in the secondary of the anode transformer 7 and a positive diode blocking potential in the secondary 33 of a transformer coupling the screen and control grids. When the valve saturates the blocking potential ceases to be developed and the cathode of diode 27 rapidly becomes negative so that a charging current flows into capacitor 21 to replace its negative charge. The value of the charging current is limited by resistor 23, which also helps to produce the desired shape of the anode current wave. Capacitor 38 and resistor 40 or an equivalent diode or other valve arrangement enables the first part of the long flank to be generated from energy stored in the circuit, and a capacitor 39 increases the natural period of transformer 35 to that of the natural period of oscillation of the deflection circuit. Synchronizing pulses are applied to a tertiary winding 41 of the screen transformer or to the cathode circuit of valve 15. In an alternative circuit (Fig. 2, not shown), the deflection coils are cbnnected in series in the anode circuit of valve 15 or across a portion of an inductor provided in series in the anode circuit. In the former case a damping resistor is connected across the secondary of an additional transformer in the anode circuit. Specification 523,476 is referred to. Reference has been directed by the Comptroller to Specification 628,742.
