Title: Method and machine for assembling fasteners with washers
Inventor: POUPITCH OUGLJESA JULES
IPC: B23P19/08
Filed: 1951-03-28
Abstract: 696,092. Assembling screws and washers. ILLINOIS TOOL WORKS. March 28, 1951, No. 7223/51. Classes 83 (ii) and 83 (iv). In a method of and machine for assembling screws and washers, the washers are fed to the machine in strip form, severance of the washers from the strip being effected after assembly. The strip is fed from a coil 14, Fig. 1, over a guide 16 to further guide means 18 grooved to engage the edges of the strip. The screws are supplied from a hopper 26 having a reciprocating agitator blade 32 to guide-rails 34, 38 leading to an incline 49, Fig. 4. terminating in curved fingers 48 tangential to a feed wheel having notches 52 correspondingly spaced to the washers in the strip. At this point the screws enter the washers and a reciprocating blade 74 aligns the shanks both longitudinally and transversely to facilitate entry. The blade is mounted and guided by screws and slots 70 and is slotted at 78 for actuation by a lever 82 having a tooth 86 engaging a ratchet wheel 88 angularly adjustable at 92 on its driving gear. The blade is connected at 98 to a return spring. The curved end 103 of a finger strips the screws from the feed wheel and further guides conduct the strip to a channel in a block 114 shaped at 122 to ensure the screws being fully seated in the washers as the shanks pass between a threading roll 126, Fig. 11, and fixed concave surface 128. At this point the washers are broken from the strip in part by divergence from the path of the strip at 130 and in part by a twisting action. The strip passes to a feed-wheel having pegs or teeth 136 that enter the holes left by the washers, feeding the strip through the machine and ejecting the scrap therefrom. The screws with the assembled washers rendered captive by the rolled thread are ejected by the threading- roll to fall into a pan 148. A motor drives a belt 186 on a pulley 160 on the shaft 154 connected by the gearing shown to the various moving parts to ensure synchronous action.

Title: Magnetic core buffer storage
IPC: G11C11/06
Filed: 1966-02-18
Abstract: 1,071,998. Circuits employing bi-stable magnetic elements. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Feb. 18, 1966 [Feb. 20, 1965], No. 7235/66. Headings H3B and H3T. In a conventional magnetic storage matrix at least the row or the column selection wires are selectively energized by write pulses, followed by read pulses which are both of the same polarity. For a storage matrix in which all the storage cores are threaded by reading and inhibit wires, Fig. 1 (not shown), the cores are initially all driven to the " 1 " state by a negative full-current pulse applied to the inhibit wire. During the following writing phase, coincident positive half-current write pulses are applied to selected row and column wires, and at the same time a negative halfcurrent pulse is applied to the inhibit wire if a binary one is to be written. Consequently the coincident half-current write pulses switch a selected core to the " 0 " state so as to register a binary zero unless switching is prevented by the inhibit pulse. Subsequently, further coincident half-current pulses, likewise of the same polarity, are applied to selected row and column wires to read out a core, the inhibit wire being unenergized. If a core was storing a binary one it is switched to the " 0 " state, an output pulse being induced in the read wire circuit which is gated open at this time. The arrangement may be applied to word-organized stores, all the cores being brought initially to the " 1 " state by full-current pulses applied to the bit wires. For writing-in a binary zero a core is switched to the " 0 " state by a fullcurrent pulse on a word wire, while for writing- in a binary one switching of a core is prevented by a half-current pulse on the bit wire. The half and full current pulses of the same polarity may be supplied from a transistor-controlled circuit, Fig. 4, in which half-current pulses pass between earth and potential-U 0  through an inhibit winding ID when transistor T1 is pulsed, while full current pulses pass between potentials +U 0  and - U 0  when transistors T1, T2 are pulsed simultaneously.

Title: Improvements in and relating to hydraulic pistons and cylinders
IPC: F15B21/10
Filed: 1955-03-12
Abstract: 799,431. Hydraulic actuators. ELECTRAULIC PRESSES, Ltd., and TOWLER, F. H., [Representative of TOWLER, J. M.]. Feb. 17, 1956 [March 12, 1955], No. 7313/55. Class 69 (2). Liquid supplied to a connection 12 of an hydraulically actuated piston 1 for opening the prefill-exhaust valve of a press, passes partly through orifices 11 in a washer 10 to act on a piston head 5 to move the piston on a forward stroke, and partly through passages 7, 3, 9 and a restriction 8 in the piston to an exhaust duct 4. The piston is thus moved at a controlled rate, and a violent surge in the line to connection 12 when suddenly supplied with liquid at a high rate of flow is prevented. When the piston reaches the end of its stroke the exhaust duct 4 is closed so that the pressure in the return cylinders of the press, which are interconnected with connection 12, can rise to its full value. A return stroke of the piston is effected by a spring, the washer 10 lifting off its seat to allow unrestricted egress of liquid from above the piston. Passages 7, 3, 9 may be dispensed with, and a clearance may be provided between the piston head 5 and the cylinder walls. The orifices in the washer 10 may be dispensed with and the washer may be a loose fit around an extension 6 of the piston, and the extension may be stepped or tapered. Extension 6 and washer 10 may be dispensed with and a one-way throttle device may be provided in a passage between connection 12 and the cylinder.

Title: Vacuum tube voltmeter circuits
IPC: G01R19/00
Filed: 1944-04-21
Abstract: 574,830. Thermionic valve voltmeters. STANDARD TELEPHONES & CABLES, Ltd. April 21, 1944, No. 7408. Convention date, April 24, 1943. [Class 37] A valve voltmeter is arranged for measuring either direct or alternating voltages. The voltage to be measured is applied between earth and an input terminal 1 connected to the grid 2 of a valve 3. The plate 5 is connected to a D.C. source 8A the negative terminal of which is earthed. The cathode 6 is connected through a resistance 7 to another D.C. source 8B having its positive terminal earthed. A resistance 10 is connected between a slider 30 on the resistance 7 and one contact 11 of a two-way switch 12, the arm of which is connected to earth through a microammeter M. The cathode 6 is also connected through a blocking condenser 14 to the plate 16 of a diode 17, the cathode 18 of which is connected to a contact 28 of a switch 27, gauged with the switch 12, and also to the plate 20 of a second diode 21. The cathode 22 of the diode 21 is connected through a resistance 23 to the second contact 25 of the switch 12 and also through a resistance 26 to the plate 16 of the diode 17. For measuring a direct voltage the switches 12, 27 are moved to the left-hand position, so that the microammeter M is connected to the slider 30, which is so adjusted that the microammeter reads zero when no voltage is applied to the terminal 1. When a positive potential is applied to the terminal 1 an increase of cathode current occurs and a corresponding reading is given. For measuring an alternating voltage the switch arms are moved to the right connecting the micro ammeter M to the contact 25 and earthing the contact 28. When an alternating voltage is applied to the terminal 1, a corresponding alternating voltage appears at the cathode 6 and is applied through the condenser 14 to the plate 16 of the diode 17. The rectified current passes through the resistance 26 and microammeter M and gives a corresponding reading. In the absence of an applied alternating voltage the emission currents of the diodes 17, 21 cancel out and produce no reading. Any unidirectional component of the alternating voltage is removed by the blocking condenser 14.

Filed: 1968-02-16
Abstract: 1,212,582. Explosive compositions. EXPLOSIVES CORP. OF AMERICA. 16 Feb., 1968 [17 April, 1967], No. 7628/68. Heading C1D. An explosive composition comprises hydrazinium nitrate, hydrazine, and ammonia. Part of the hydrazinium nitrate may be replaced by hydrazinium perchlorate or by Na, K, Ca, or Al nitrate or perchlorate. The ammonia lowers the freezing point of the composition; other additives for this purpose are hydrazinium thiocyanate and monomethyl hydrazine. As desentitizing agents the following may be added: water, glycerine, glycol, or hydrocarbon oil. The composition may be in the form of a liquid of low viscosity or may be converted into a gel by adding finely divided silica, methyl acetate, cross-linking polysaccharide, or carboxy vinyl polymer. Polyethylene oxide resin may be present as a waterproofing agent. To assist the adsorption of the liquid explosive by porous media, a wetting agent may be included; for example dimethyl sulphoxide, dimethyl formamide, ethanol and propanol. Water or sand may be included to reduce the detonation velocity. To bring about desensitization or destruction of the explosive after it has been placed in position, capsules may be added made of a material soluble in hydrazine and containing, for example, water for desensitization or iodine pentoxide or nitrogen tetroxide for deflagration. The composition may be prepared by mixing ammonium nitrate, with or without ammonium perchlorate, with hydrazine; ammonia is evolved and hydrazinium nitrate is formed, excess ammonia being removed by vacuum or by heating. Alternatively, cloth or sponge impregnated with ammonium nitrate, or ammonium nitrate by itself, may be placed in position for use, and then the hydrazine added. The composition may also be used for the explosive laminating of a metal sheet to a solid substrate.
