Patent GB-488876-A (GB)
Abstract: 488,876. Cash registers. GLEDHILL, A. H. Feb. 18, 1937, Nos. 4852, 10852, and 18958. [Class 106 (i)] Autographic arrangements; taking totals and subtotals.-In order to ensure that the amount in the cash drawer shall be recorded prior to the printing or indicating of a total or subtotal, the amount is written on a disc carried by a turntable in a hinged casing, which casing is provided with a cover, normally occupies a position in which it prevents access to the total-taking mechanism and, upon being moved to access-giving position, rotates the disc to move the entry thereon past a writing aperture. The invention is described as applied to a machine of the kind forming the subject-matter of Specification 368,785. Having ascertained the amount of cash in the till at the end of a day, the clerk raises a shutter e, Fig. 2, in. the cover E of a casing C, thus revealing an aperture giving access to a radial division of a disc-shaped card A, Fig. 3, wherein he enters the amount. The raising of the shutter disables a latch F and enables the clerk to rock the casing about a shaft D, thereby uncovering the total and subtotal taking locks and advancing the entry on the card past the writing aperture. For this purpose, a ratchet wheel b<2>, rigid with a turntable B carrying the card is rotated one step by a pawl b<3>, mounted in the casing and actuated by a cam b<8> fixed to the machine housing. The clerk now inserts and rotates a key in one of the locks whereby he is enabled to take a total or subtotal in the usual manner. Restoration of the casing C during the operation is prevented by a stop lever g<8>, Fig. 2, that is rocked clockwise about a shaft g<7> upon the rotation of either lock barrel to releasing position. Return of the lock barrel disables the stop lever to permit the casing to be restored and relatched. The operation may be repeated until the divisions of the card have all been filled, when the feed-pawl b<3>, Fig. 3, encounters a mutilated part of the ratchet wheel and the turntable becomes locked by a detent b<11>. The cover E is normally locked to the casing C by a bolt h<11>, but upon the opening of the total-taking lock the bolt is withdrawn and the cover mav be rocked about the shaft D to enable the card to be removed. The detent b<11> is now manually disabled, the turntable advanced to starting position and a new card applied thereto. Removal of the record strip from its winding drum j<1>, Fig. 2, is permitted only when an upstanding part e<4> of the cover is rocked out of blocking position by the opening of the cover.

Abstract: 1534330 Electronic watch DAINI SEIKOSHA KK 30 Nov 1976 [4 Dec 1975 19 Dec 1975] 49829/76 Heading G3T In a digital electronic watch, hours and minutes are normally displayed and seconds are periodically displayed, e.g. for 0.5 secs every 5 secs or 10 secs, on the same display devices (LCD or LED) as used for minutes. Ambiguity is avoided by the automatic extinction of the hours display when seconds are displayed. The watch Fig. 1, comprises a crystal controlled oscillator 1, frequency divider 2, secs, mins and hours counters 3, 4, 5 respectively. A control circuit 13 detailed Fig. 2 (not shown) produces a control pulse H of 0.5 secs duration every 5 secs. When the pulse is low, a selector gate circuit 10 (detailed Fig. 2) is enabled to couple the output of the mins counter 4 to a de-coder 11, driver 12 and display elements 8c. When the control pulse H is "high" the seconds counter 3 is coupled to the display by selector 10; simultaneously the pulse H controls a phase reverser circuit 14 causing it to apply a 32 Hz signal to the hours driver 7 and hours display elements 8a instead of an inverted 32Hz signal. Since the common display electrode is directly connected to the 32Hz signal, the hours display devices will not be activated. Colon dots 8b are activated by a driver 9 controlled by a 1Hz signal from the divider 2. In an alternative embodiment Figs. 5-8 (not shown) seconds are displayed every 10 secs, the control pulse being the output of a 10-sec counter (103), the seconds indication being 00, 10, 20 etc. A circuit 15, not described, is provided for setting.

Abstract: 1,206,524. Rotary positive-displacement pumps and motors. LEAR SIEGLER Inc. Oct.31, 1968 [Nov.13, 1967], No.51639/68. Heading F1F. A rotary positive-displacement hydraulic pump, or motor, of the externally-meshing gear type includes a pair of gears 14, 15, Fig.1 lodged between pairs of axially-movable bearing-blocks 19, 20 and 21, 22, the blocks 20, 22 being pressure-loaded in the axial direction to minimize leakage of fluid from the ends of the geartooth spaces, to which end a seal 25 is situated in a groove 26 within an end plate 13 of a housing 10 to form pressure-loading chambers. The seal is constituted by a resilient element 27, Fig.2, and a wear-resistant element 28, each element having limbs, or projections 41, 42 whose outermost ends are in register with the outer peripheral surfaces of the adjacent bearing-blocks so as to form a pair of chambers, or "zones", 43 that are isolated from inlet and outlet ports 23, 24 for the working fluid and to prevent direct communication between said ports. The chambers 43 are charged with fluid through channels 44, or 45, in the bearing- blocks, which channels communicate with geartooth spaces remote from the meshing gear-teeth so that the distribution of pressures urging the bearing blocks towards the gears suits the pressure gradient across the gear teeth. Additional projections may be furnished between the projections 41, 42 to form extra pressure-loading chambers. To flush the peripheral surface of each bearing block a channel 38 may be provided, as shown, to permit fluid to flow therethrough from the geartooth spaces into a region of relatively lowpressure adjacent the inlet port 23. Flushing of the surface aforesaid is also effected by fluid in the channel 44, or 45. An additional groove 30 contains a ring 31 to prevent leakage between the end plate 13 and the central section 11 of the housing, fluid entering this groove being directed into the inlet port through grooves 37. The projections 41, 42 may be furnished with axial extensions, or legs, 49, 50, Fig. 4, to more effectively seal the chambers 43; and the elements of the seal may be lodged in a groove 54 formed in a bearing-block 51, which replaces the blocks 19, 20. Alternatively, a groove for said elements may be formed in the housing end-plate as well as in the bearing- block. In another embodiment, Fig. 5 (not shown), the bearing blocks are replaced by cheek-plates, or pressure-plates, (72, 73), the gears being supported by bushes (66) in the housing.

Abstract: 1,098,300. Inverter circuits. GENERAL PRECISION Inc. Dec. 30, 1964 [Dec. 30, 1963J, No. 52883/64. Heading H2F. In a D.C. to A.C. converter, an output signal having a low harmonic content is produced by adding together harmonically related square waves. In a simulator, Fig. 1, digital data required to operate synchro motors M-1, M-2 is converted to analogue form and fed to modulator 42a, 42b &c., which chops the analogue signal to form a variable amplitude square wave. In order to reduce the harmonic content this signal is " notched " at suitable points, Fig. 2 (not shown) by relatively short pulses derived from oscillator OSC. The oscillator output is fed to a divider chain FD comprising 8 divide by two stages and the outputs from the various divider stages are combined in a notching logic circuit 50, to produce on line 70 a pulse train Fig. 6 (not shown), which chops the square wave signal so as to reduce the lower harmonics. High harmonics are then reduced by filter 43a, 43b &c. In a second embodiment, Fig. 10, the sinusoidal output is synthesized by adding together harmonically related square waves having suitable amplitudes. The square waves are derived from dividers and are used to control transistor gates T-1, T-3, T-5, T-7 so as to pass the input signal from terminal 10 to a summing circuit U-2 where after weighting by resistors R1, R3, R5, R7 they are added to produce a waveform 11(e) (not shown), having only higher harmonics present. These are then removed by filtering as before. In a modification of the second embodiment Figs. 13, 14 (not shown), the signal is synthesized from harmonically related triangular waves, and subsequently integrated.
