Title: Improvements in or relating to fluid operated jacks
IPC: B66F3/42
Filed: 1937-09-27
Abstract: 503,081. Reciprocating pumps. LAKE & ELLIOT, Ltd., and BARRETT, H. R. Sept. 27, 1937, No. 26145. [Class 102 (i)] [Also in Groups XXX and XXIX] A fluid-pressure jack of the multi-ram type having pump plungers of different diameter, is characterized in that the plungers are connected with separate means for receiving an operating handle or lever, these means being so arranged that the handle may be connected with each separately or with both simultaneously whereby the plungers may be operated independently or together to enable all the rains to be raised by the exertion of substantially the same effort on the operating handle or lever. Figs. 1, 2, 3 show an embodiment in which fluid is pumped from a reservoir 5 to a cylinder 1 to raise rains 12, 13, 14 by plungers 36, 40. These plungers are reciprocated by a handle 35 which is connected to the jack by members 29, 30 on shafts 24, 25 connected to the plungers by links 27, 28. These members 29, 30 comprise sockets 31, 32 with parts 33, 34 which together form a socket to receive the handle when it is desired to operate both plungers simultaneously for raising the ram 12. The outward movement of the rams 14, 13 is limited by spring-pressed rings 16 engaging in recess 18 in the rams 13, 12, and that of the ram 12 by the flange 20 engaging a washer 21. To lower the jack, a trigger 44 connected by a rod 45 to a sleeve 46 is operated so as to pivot a lever 47 and depress a plunger 50 to open a release valve 51. In a modification, the members 29, 30 are carried by the links 27, 28 which are rotatably mounted on stationary shafts 24, 25. In another embodiment, Fig. 11, the handle 35 engages in a socket 64 on the shaft 24 and is provided with a slidable sleeve 68 having projections 67, 71, 72 engageable in grooves in members 66, 74 on the shafts 24, 25. The sleeve 68 may be adjusted by a rod 69 manipulated from the distant end of the handle so that the projections engage in the grooves of one or both of the members 66, 74. In another modification, Fig. 14, the handle engages in a socket 75 on the shaft 24, the socket being pivotable about a pin 77 so that projections 80, 81 on the handle may engage in one or both of the open-sided socket members 78, 79 secured on the shafts 24, 25. A gate 82 ensures correct positioning of the handle.

Patent GB-263129-A (GB)
Abstract: 263,129. National Cash Register Co. Dec. 17, 1925, [Convention date]. Cash registers; keyboards. -In a machine, for example of the Shipley type described in Specifications 8119/15 and 176,781, the key controlling the entry of items in the listing totalizer is locked in depressed position until the list total is taken. In addition to the usual operating and locking detents 4, 3, the control bank containing the list key 1<a> is provided with a detent 8 formed with a locking nose 14 to seize a flattened elongated pin 2a on the key stem and hold the key down throughout the series of listing entries. During the two-cycle operation the shaft 13 is rocked in the known manner and lowers the detent 8 so that the pin escapes from the nose 14 and it is then held by the lug 17 the key rising slightly however owing to the lug 7<a> being partly cut away. Subsequently the detent 8 returns to normal position and the detent 3 at its second displacement finally releases the key. While the key 1<a> is depressed the other keys of the bank are inoperative owing to the key pin 2<a> entering a radial slot in the operating detent 4 of the bank. Specification 227,861 also is referred to.

Abstract: 1407666 Electrophonic musical instrument MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 June 1973 [3 June 1972] 26614/73 Heading G5J In an electrophonic keyboard instrument each note played is derived from a high frequency master square-wave oscillator 6, optionally with subsonic vibrato frequency modulation 13, via a variable ratio divider 5 capable of providing the 12 semitones of an even tempered scale, further subdivided by five divide-by-two circuits in 7 providing three octavely spaced square waves, having one or two divide-by-two circuits suppressed for successive octaves above the bottom octave of the keyboard. If two or more notes are played together, priority circuits in control 2 determine which is played. The three outputs are filtered separately 10 before combination in order to adjust harmonic structure appropriate to the octave in which the active key lies, and are gated 9 under envelope control 8 to provide desired rise and decay; if decay is made long a note is sustained after key release, memory 3 maintaining control of dividers 5 and 7, envelope control 8 and filters 10 when the key is released, cleared by pressing any further key. Alternative circuits for control 2 and memory 3 both include flip-flop circuits for each of the 12 semitones in an octave; priority circuits detect whether more than one of the three octaves on the keyboard is activated, and ensure that only one, either high or low, is sounded. Other priority circuits detect which notes, independent of octave, are activated and determine which, either highest or lowest, is to be sounded in the selected octave. Transistor circuits for resetting the flip-flops, for detecting more than one octave and more than one note, and for isolating any octaves to be inactivated are illustrated (Figs. 10, 11, not shown). The encoder 4 connects certain of 12 conductors to a power supply via a matrix of diodes, translating the binary code defining the division ratio which varies from 1850(C) to 3492(C # below), acting on a master oscillator frequency of 7À744 MHz. For the lowest keyboard octave the fundamental is the result of a further division by 32. As an alternative to a memory circuit storing the key position, the binary code may be retained.

[Also in Groups XVI, XIX and XL (c)] A bistable storage unit used in a printing machine recording the read-out of a computor comprises a series of magnetic cores. Each core is coupled to the gated output of a print word counter gating and buffer circuit and to receive the output from print storage flip-flops so that upon the presence of signals at say row line 621, Fig. 6a, and column line 626 the core unit 2126 is set. One core unit is shown on Fig. 6b having a transistor 601. The collector 601 is coupled to the anode of a diode 602 and through a resistor 603 to a high potential ; the transistor is normally biased non-conducting in the absence of a positive pulse applied to the base. When a positive signal is supplied to incoming line I 1  and the transistor is cut-off, there is insufficient potential difference to cause current flow in winding 606. When however a pulse I 2  is supplied from the print word counter gating and buffer circuit the base-to-emitter bias of the transistor causes conduction between the collector and the emitter. When there is a signal on both circuits, current flows through the diode 607 and through the winding 606, causing the core to change its state. To read out from the core a signal on line IS resets core by winding 610 and causes a pulse from winding 612 to output line 0.
