Title: Improvements in coin counting machines
Inventor: RAND LEONARD ALEXANDER
IPC: G07D9/04
Filed: 1959-08-28
Abstract: 887,803. Counting-apparatus. INTERNATIONAL COIN-COUNTING MACHINE CO. Ltd. Aug. 25, 1960 [Aug. 28, 1959], No. 29534/59. Class 106 (1).  In a coin-counting machine of the type in which coins are pushed by a driving-wheel past a counting mechanism into a holder, the driving-wheel being raised after a predetermined number of coins have been counted, the coinholder is rockable to remove the coins, means operated by the return of the coin holder to the coin-receiving position being effective to lower the driving-wheel into its coin-counting position. As described, coins 3 to be counted are fed by a rubber driving-wheel 1 past a star-wheel 5 which operates a counter (not shown). The star-wheel 5 is fixed to its spindle 8 which carries a pawl 9 engaging a toothed ratchet wheel 10 carrying a pin 11 which, when a predetermined number of coins has been counted, moves a slidable plate 12 to release a ram 13 for upward movement under the action of a spring 14, thereby raising the wheel 1 from the coins. The counted coins fall into a holder 15 comprising a tube closed at one end 16. The holder 15 which is at an angle to the vertical, is rotated clockwise through 90 degrees to remove the coins therein. Alternatively, the holder 15 may be vertical and inverted to remove the coins. The holder 15 is then returned to its original position, thereby rotating a ratchet-member 26 to drive a co-operating ratchet-member 29 carrying a cam 31 co-operating with a bell-crank lever 33, an arm 34 of which engages a clot in a lift-plate 36 fixed to the ram 13 which is thus depressed against the action of the spring 14 to re-engage the wheel 1 with the coins. Reference has been directed by the Comptroller to Specification 613,357.

Abstract: 481,494. Making welding electrodes. KOHLEUND EISENFORSCHUNG GES. Oct. 30, 1937, No. 29685. Convention date, Jan. 19. [Classes 83 (ii) and 83 (iv)] Arc - welding electrodes containing cores of flux or the like are made by rolling or drawing blanks consisting of two or more superposed blocks, preferably square or oblong, provided on their abutting surfaces with longitudinal grooves to receive the flux or the like. Blocks 1, 2 formed with grooves 4 by rolling or machining are superposed and welded continuously or intermittently along their edges 6, the flux &c. being inserted either before or after assembly. The welding of the blocks may alternatively be effected during the rolling or drawing operation. The blank is rolled &c. down to circular form as shown in Fig. 1a or elliptical or other form to produce an electrode with a flux &c. core. In another form the two blocks may each have a single central semi-circular groove to produce an electrode with a central flux core. In a further form, Fig. 3, four superposed blocks may be used with grooves so as to provide a number of cores 8-12. The central core may contain alloying material and the outer cores substances for stabilizing and ionizing the arc and also for forming slag and protective gas. The blocks may be provided with grooves of different sizes or shapes so as to vary the action of the electrode, e.g. the central core may be larger than the outer cores.

Title: Improvements in automatic ink-ribbon reversal mechanism
IPC: B41J33/518
Filed: 1924-12-10
Abstract: 236,106. Royal Typewriter Co., Inc., (Assignees of Handley, G. F.). Oct. 29, 1924, [Convention date]. Ink-ribbon mechanism.-Automatic ink-ribbon reversal mechanism is controlled by a slidable ribbon guide, which is preferably actuated by a projection on the ribbon, and is connected to the ribbon-feeding mechanism by a lost-motion connection, permitting the ribbon to be fed while the slidable control is being operated to effect its reversal. The shafts 1, Figs. 1 and 3, carrying the ink-ribbon spools E are supported in the offset arms 2, 3 of brackets 4 attached to the typelever segment. Bevel gears 5 at the ends of the shafts are driven in known manner bv either of two bevel wheels 6, 7 at the ends of a longitudinally movable shaft 8 carrying a pawl-driven ratchet-wheel 10, which is fed at each depression of a type key. The ribbon guide 20 adjacent to each spool consists of a slotted vertical portion, through which the ink-ribbon passes, and a horizontal portion provided with a slot 22 to engage a headed guide screw 23 on a horizontal arm 24 on the bracket 4. The outer end of the horizontal portion of the ribbon guide is pivoted at 25 to the upper arm 26 of a bell-crank lever 30, which is pivoted at 27 to an arm 28 projecting from the bracket 4, the lower arm 29 of the bellcrank being provided at its end with a shouldered screw 31 which works within a slot 32 at the upper end of a vertical member 33. The lower end of the member 33 moves within a guide slot in a plate 40 attached to the frame, and is provided with an offset pawl 41 adapted to move the shaft 8 longitudinally when it is lifted into engagement with a spiral or worm wheel 42 fixed on the shaft. A spring 34 connected between an ear 35 on the bell-crank lever and an ear 36 on the pawl-carrying member 33 provides a yieldable connection between them. Fig. 3 shows the lefthand spool, wherein the projection 21 on the inkribbon G moves the ribbon guide 20 into the position indicated by dotted lines, the spring connection between the guide and the reversing means enabling the ribbon to be fed until the longitudinal movement of the shaft 8 causes a spring detent 17, Fig. 1, to over-ride a collar between two grooves 16 on the shaft, thereby completing the reversing movement quickly. The springs 34, 37 return the parts to their normal position when the ink-ribbon commences to feed to the left.

Title: Modified copolyesters
Inventor: DELVES ALLAN KENNETH
IPC: C08G63/688
Filed: 1964-07-27
Abstract: A film- or fibre-forming copolyester contains a minor proportion, e.g. 0.5-10 mol. per cent of the total, of structural units containing at least one sulphonate group in the form of the metal salt, and a minor proportion also, e.g. 0.1-0.8% of the total weight, of a basic nitrogenous organic compound.  Suitable polyesters may be derived from terephthalic acid or bis-(p-carboxyphenoxy) ethane, which may be used conjointly with isophthalic, adipic or sebacic acid, and the dito deca-methylene glycols or 1:4-bis-(hydroxy-methyl) cyclohexane. The sulphonate group may be contained by a dicarboxylic acid or a dihydric alcohol.  The basic nitrogenous compound may be introduced into the polyester (i) with any of the starting materials for the formation of the polyester, (ii) after formation of the polyester and before shaping, (iii) during shaping or (iv) after shaping. In examples, a copolyester from dimethyl terephthalate, ethylene glycol, and sodium dimethyl isophthalate-5-sulphonate is (1) melted and spun, 2-diethylaminoethyl nicotinate being applied to the thread while still molten, and (2) ground with tribenzylamine, then melt-spun to give fibres.

Abstract: 1301737 Control of D.C. motors; protective arrangements MIITSUBISHI DENKI KK 19 June 1970 [19 June 1970] 29957/70 Headings H2J and H2K A filtering capacitor CF in the circuit of a D.C. motor A, F, operating in a regenerative braking mode is protected from overvoltage in the event of removal of the effective regenerative load RL by passing the motor current through a resistor via control switch TH, which may be a thyristor, closed by a signal from an overvoltage detector OVD, whenever the voltage across CF exceeds the nominal line voltage by a given amount. Detector OVD also causes current reducing device HB to open, connecting resistor R HB  into the circuit, the latter switching alone being too slow to protect capacitor CF. The resistors R and R HB  limit the motor current so that switch LS can open without flashover damage to components. The device OVD may be a D.C. potential transformer and PNPN switching device. Resistor R, and switch TH need only be of sufficient size to carry transient currents, and may be connected on the cathode side of diode D D , so that CF is discharged to the line voltage, but must then be of larger current carrying capacity. Device OVD may be connected to the anode of D D . The system may also be used with shunt or compound wound motors. Thyristor CH acting as a chopper controls the motor during normal regenerative braking.
