Patent GB-455133-A (GB)
IPC: G07B1/02
Abstract: 455,133. Ticket - printing machines. HANDLEY, J., and SUCKLING, C., 22, Sandringham Road, and SUCKLING, R. H., 19, Heather Gardens, both in Golders Green, London. Jan. 9, 1935, No. 17268 /36. Divided out of 454,920, [Group XIX]. [Class 100 (iv)] [See also Group XIX] In a ticket printing and issuing machine the means for selecting the number types comprises dials provided with manually operable plungers and rotatable through variable distances determined by the plungers. As shown in Figs. 1 and 2, plungers 55 are provided on the tens and units dials 53, 54 which may be rotated by the plungers until stopped by engagement of depressed plungers with latches 57, Fig. 3, which normally retain a vertical locking plunger 59 out from engagement with locking apertures in the dials. When the latches are operated the plunger is moved upwardly to engage apertures 63, Fig. 2, and lock the dials. Printing and issuing a ticket is effected by manual operation of a lever 1, Fig. 1, which operates a pivoted rack 4 through pins 3, 3a. When the lever 1 is pushed forwardly the rack 4 operates arms 12 to move rollers 16, 17 arranged on each side of the paper strip p and downwardly along the guides 15. Return movement of the lever 1 and rollers 16, 17 feeds the strip through the machine and subsequently a guillotine 22 is actuated through the link 24. Printing is effected by a cam 34 which depresses the platen 33 upon each forward movement of the lever 1 until the forward stroke is completed when the pawl 5 is thrown out of engagement by a projection 6 to allow free return of the rack. When the dials are in their zero or " test " ticket positions, the rack 4 is locked by a plunger 66, Fig. 2, but upon operation of the dials and upward movement of plunger 59, the plunger 66 is released bv the end of 59 to free the rack. Furthermore, the dials cannot be released until the lever is restored to zero since a plunger 64 which co-operates with notches at the zero positions of gear-wheels 51, 52 prevents restoration of plunger 59. When the lever 1 returns and a ticket is issued, the rack 4 is stopped by pin 3a, but lever 1 continues its movement and a catch 91 returns the plunger 59 through a link 61 and thereby allows the dials to restore. Specifications 454,920, 455,006, and 455,134, [all in Group XIX], are referred to.

Abstract: 1,196,637. Developing electrostatic images. RANK XEROX Ltd. Oct. 6, 1967 [Oct.11, 1966], No. 45730/67. Heading G2H. An electrostatic latent image on a drum 10 is cascade developed by a developer having a toner and carrier supplied in random manner by buckets 14 to full under gravity between plates 20, 22. A development electrode 26 of conductive material is biased by a potential source 32 to the same polarity as the image areas and opposite to that of the toner, the potential being higher than that of the non-image areas such that toner is attracted away from such non-image areas to reduce background. A second electrode 28 biased to a high potential, e.g. 1500 volts and of opposite polarity to the toner particles attracts clouds of toner formed by the cascading toner some of which accumulates on the electrode while the remainder is drawn into the flow of the cascading carrier particles. In another embodiment Fig. 3 (not shown) a development electrode (36) and a second electrode (40) are mounted on a member (38) and connected to separate potentials. A baffle (46) carries a biased insulating layer (50) and plate 48 to collect toner which has fallen beyond the electrode (40).

Title: Apparatus for setting bowling pins on a bowling alley
IPC: A63D5/08
Filed: 1964-11-10
Abstract: The pinsetter of a bowling alley comprises a vertically displaceable pin setting carriage provided with pin support elements, means mounting each pin support element on the carriage for pivotal movements about a substantially horizontal axis, holding means for retaining the bowling pins upon the support elements and releasing means for rendering ineffective the holding action of the holder means when the associated bowling pins are in a substantially erected position, the pivotal movement of the support elements being a function of the vertical displacement of the pin setting carriage. As particularly described, each pin support element 20 comprises a support 21 for the body of the pin, together with a system of pivoted linkages spring-controlled to engage with the head of the pin, the support and linkage members together being mounted on a cross member 24 which is rotatably supported in the frame of the pinsetter.  All of the cross members 24 are caused to pivot or rock about their horizontal axes in synchronism with the vertical displacement of the pinsetter.  As the cross members pivot during the descent of the pinsetter, the pin holders 20, the pin holders also pivot to bring the associated pins to the vertical position the pinsetter being arranged to continue its descent after the butt ends of the pins contact the playing deck of the alley, whereby each pin head causes the corresponding lever 22 to pivot upwardly about 23 against the action of spring 33.  This upward movement of lever 22 is transmitted to lever 30 via link 28, causing lever 30 to pivot about 31 the gravity-operated detent 34 then becoming effective to hold the lever 30 in its displaced position so that on subsequent upward movement of the pinsetter, the pin is released from the holder.  During ascent of the pinsetter, the shafts 24 rock in the opposite direction to re-set the pin holders to their pin-engaging condition.  Members 25 depending from the pin supports 21 are operative to close switches in circuit with indicators in the event of their contacting standing pins during scanning sequences.

[Also in Division G4] Code translating, analogue signal generating and scanning circuits are provided by modifications of the circuit of Fig. lb in which transfluxors 20 1 -20 10  having at least three apertures have a common prime winding 43 and a common advance winding 44 through one aperture, this aperture also being coupled to the second aperture of the next core in the series by windings 21 so that the " ONE PRIMED " state produced in transfluxor 20 1  by a current from WRITE source 31 and priming pulse in winding 43 may be transferred down the series by successive prime and advance pulses until all the transfluxors 20 1 -20 10  are in the ONE PRIMED state and the next advance pulse from source 34 produces a pulse in conductor 42 which activates detection circuit 32 which causes next source 35 to reset the transfluxors 20 1 -20 10  to the ZERO state. Parallel to aerial converter (Fig. 2a).-Binary input signals on lines B 1 , B 2 , B 3 , B 4  set some of the cores 50 1 -50 10  in the series to the ONE state the core nearest the end of the series which is set to the ONE state being different for each input combination. Prime and advance pulses are then applied and the number of pulses required to advance the ONE state from core 50 10  is counted by detection circuitry 71 which gives a serial output. The pulse in winding 27 switches flip-flop 61 which then reacts the device to its initial condition. Analogue signal generator (Fig. 3a, not shown).-All the cores have a common output winding which produces an output indicative of the number of cores in the " ONE " state and thus the number of pulses applied since the first stage was set to " ONE." By adjusting the number of output turns on each core the output may be linear or exponential. Scanning circuit (Fig. 4, not shown).-Each neighbouring pair of cores in the series has a pair of common oppositely-connected output windings so that an output is obtained only from the winding corresponding to the change from the " ONE " to the " ZERO " state in the series. Serial to parallel converter (Fig. 5b) uses four aperture transfluxors, five output windings O 0 , O 1 , O 2 , O 4 , O 7  being divided between the cores so that two are coupled to each but the outputs produced by switching the cores in the " ONE " primed state add and subtract to produce a " 2 out of 5 " signal corresponding to the number of cores transferred to the " ONE " state by serial input pulses. As shown in Fig. 5b the turns ratios in the transfer circuits 111 may be greater than 1 to improve the switching time.
