Title: Apparatus for controlling the locking of containers or the like  on an orbitable carrier of a mechanized article storage device
IPC: A47B88/16
Filed: 1974-04-23
Abstract: 1429748 Endless conveyer-type filing cabinets SPERRY RAND CORP 23 April 1974 [25 April 1973] 17701/74 Heading B8A Containers 17 for file cards 15 supported on an endless carrier 13 and slidable on the latter from an outward card viewing position (Fig. 1) to an inward transport position (Fig. 3), are pushed by a spring 31 to obturate a light beam 41, if the carrier is not pushed right home into true locking position. The front of each container 17 has two projecting locking members 23, rigid respectively with each side of the container. In the final inward movement of the container, the members 23 spring back respective bevelled inembers 27 carried by the carrier 13 and lock behind them. During this action, lugs 33 on respective sides of the container, engage spring- loaded plungers 35. If the latch 23, 27 does not fully engage on either side, the respective plunger 35 pushes the container to a slightly outward position, thus obturating the light beam 41 (Fig. 5). This is arranged to cut-off the drive of the carrier 13. The latches 23, 27, may be released by operating a member (25) forming part of the handle (30) by which the container is manually pulled in and out. The member (25) actuates bell-cranks (53), (53), connected to the members 23, 23.

Abstract: 1,268,462. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 14 April, 1970 [14 April, 1969], No. 17777/70. Heading H4P. In a data transmission system wherein each primary digit is represented by a sequence S comprising a main signal pulse and a predetermined number of preceding and following echo pulses at determined intervals, for each sequence, a series S<SP>1</SP> is generated comprising symmetrical pulses of the form  which is summed with the corresponding sequence S and passed through a low pass filter producing a signal, to be transmitted, of a form capable of being demodulated in a conventional device operating at the data repetition rate Ts. The transmitter includes a generator of elementary signals representing data elements, which are received by a register having a number of positions determined by the number of weighted pulses and/or time duration of each signal, a means for generating the series S<SP>1</SP>, and an analogue adder under the control of clock signals which produces a corresponding signal amplitude in respect the values obtaining at the input and/or the positions in the register. Alternate signals may be inverted. The transmitted signal is substantially identical to a frequency modulated signal which may be received by a conventional f.m. demodulating device. Sequences A, B of main and echo signals S representative of individual data elements are shown in the upper two lines of Fig. 1, B being shown inverted and the value of each element being represented by the amplitude. A signal of the form S<SP>1</SP> is generated for each group, that for A being shown in line 6 which signals have an amplitude of 0À707 A max. Each group of signals S<SP>1</SP> is added to the corresponding group S in an analogue adder which after passing through a low pass filter gives a signal of digital type which may be transmitted and which is substantially identical to a f.m. signal. Arrangements for generating and combining the signals are described in the Specification.

Abstract: 795,307. Spark gaps. METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 15, 1955 [June 18, 1954], No. 17993/54. Class 39(1). [Also in Group XL(c)] Spark discharge switching apparatus comprises a plurality of short spark gaps arranged in series and of sufficient number to enable the gap assembly to withstand the voltage for which the apparatus is designed without discharging, means for applying a triggering voltage across one or more of the individual gaps to cause a discharge which triggers the remaining gaps until there is a spark discharge path through the whole assembly, and liquid cooling passages through all the electrodes to ensure rapid deionization after the discharge. In one arrangement, Fig. 2, the sparking faces of the electrodes are formed by plates 13 mounted on pipes 14 carrying cooling liquid. The electrodes are mounted on insulating blocks 10 and 11 held apart by screwed rods 12 which permit adjustment of the gap lengths. Alternatively the plates 13 may be omitted, the electrodes being formed by the pipes 14 which may be arranged in a lattice formation to provide spark gaps at the points where the electrodes cross over each other. Suitable electrode materials are copper, tungsten, copper-tungsten, silver-tungsten, and molybdenum. Brass is not suitable owing to the presence of zinc. In an alternative arrangement, Fig. 7, the electrodes are formed by a stack of circular plates 17 spaced apart by annular insulating rings 18 and each having a sparking face 19 formed on one side. Two or more holes 20 are provided through each plate to equalize the pressure within the assembly. Holes 21 drilled through the plates communicate with outlets 22 for the discharge of unwanted gases and deposits. Water-cooled ducts (not shown) extend through the electrode plates 17 for cooling purposes. The ducts 21 and 22 may be omitted in the end electrodes of the stack, and the assembly may be pressurized with air, nitrogen, hydrogen, carbon dioxide, or argon, or may be operated at atmospheric pressure with a small gas flow to remove waste products or with a small flow of an inert gas to prevent air from entering the assembly. The multiple spark gap may be connected in a pulse generator switching circuit (see Group XL(c)) in which a storage circuit such as a capacitor or artificial line is first charged and then discharged through a load circuit by triggering the spark gap.

Abstract: 781,297. Valves. WILD & CO., Ltd., A. G. Aug. 3, 1955 [June 21, 1954], No. 18100/54. Class 135. In an automatic-hydraulic pressure-relief valve comprising a main closure-member 5 normally held on its seat by a spring 23 and hydraulic pressure acting in opposition to the pressure on a larger area, such as a piston 11, operatively associated with the closure member, a manually-operated device, for example a valve, is provided for assisting the hydraulic pressure acting on the larger area to open the closure member 5 when desired. The fluid in the inlet 2 both acts on the closure member 5, urging it on to its rubber or like seat 18, and flows through a bore 13, and ports 14, 15, the former of which is smaller than the latter, to act on each face of the piston 11 having a plunger 9 that abuts the stem 19a of the member 5, the pressure difference between the faces of the piston being proportional to the cross-section of the plunger 9, that is made slightly greater than that of the member 5, whereby the resultant force tending to lift the latter is small and a light spring 23 is normally sufficient to hold the member 5 on its seat. When the inlet and hence the resultant pressure increases and overcomes the spring 23 the valve 5 is opened and the fluid in the inlet 2 is then in direct communication with the outlet 3. The member 5 may be opened by actuating the manual valve that exhausts the space on the plunger side of the piston 11. A screwed cap 12 for the piston chamber may be provided to impart a thrust to the piston to open the member 5 upon manual rotation thereof. The valve chamber 4 may incorporate threaded bores for the reception of a non- return valve and a pressure gauge, not shown. In a modification, the plunger, one of the ports and the manual valve are dispensed with, the closure member being manually opened by rotating a cylinder having a cam surface which, through a spindle, imparts a thrust to the closure member.
