Abstract: 316,855. Russ, J. B., (Assignee of Gallagher, D. M.). Aug. 3, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts] . Catches, automatic; hasp fastenings and locks; latches, sliding; lock mechanism operated by non- rotating key.-A fastening or lock, shown as mounted on a hinged hasp-plate 2 with an aperture 40 through which a staple 28 passes, has a number of sliding latch bolts (three shown) 18, 20, 22 biassed to the right by springs 24 and having bevel projections 26 adapted to engage in the staple 28 as shown. Projections on the bolts, guided in slots 38 limit movement of the bolts. Normally, projections 26 are in alignment, and the bolts are of different lengths so that their rear ends are out of alignment. To release the catch the rear ends of the bolts are pressed inwards by a sliding key 12 having shoulders 16 (Fig. 6) stepped to correspond with the ends of the bolts so that the bolts are moved simultaneously. The free end 10 of the hasp plate 2 and the end 14 of the key are upturned to facilitate operation by gripping. The key may be removed, or may be left in place, where it is returned frictionally by a spring 46, so that the device may be used as a keyless sliding catch. The bolts &c. are enclosed in a case or cover 48 riveted to the plate 2 and with an aperture to allow insertion of the key. A form is described in which the hasp plate is double-hinged.

Title: Improvements in or relating to apparatus for compressing gases
IPC: F04F5/08
Filed: 1924-12-30
Abstract: 249,613. Hydrautomat, Ltd., and Boving, J. O. Dec. 30, 1924. Blast apparatus, injector. -Relates to apparatus for compressing gases of the kind in which the gas to be compressed is entrained in a body of water which descends by gravity through a compressor conduit to a separating chamber where the entrained and compressed gas is released, and consists in facilitating the separation of gas and water by causing the mixture to flow into the separating chamber in a thin layer or sheet over a lip the edge of which is above the normal level of water in the chamber. An apparatus of the Taylor type is shown, having an air induction head A<1> of any usual construction at the lower end of the compressor conduit the mixture is caused to flow over a lip A<3>, the thin layer thus produced parting readily with bubbles. Compressed air from the chamber B passes away by a pipe diagrammatically denoted bv D. Preferably, curved vanes A<4> give the descending mixture a rotating movement, whereby the water is flung outward, thus further facilitating the separation of air. In modifications, the mixture flows over a partition fixed in the separating chamber. In other modifications, the lips are mounted on floats.

Filed: 1972-07-05
Abstract: 1361950 Polarized relays SIEMENS AG 5 July 1972 [7 July 1971] 31370/72 Heading H1N A bi-stable polarized relay has a permanent magnet 5 and a pole shoe 6 which covers a subsidiary zone pole face of the permanent magnet 5 to convey flux to a main armature section 8 whilst flux is conveyed from a second, subsidiary, zone 5b mainly via an auxiliary armature section 9. When the relay coil 1 is energized in one direction its flux assists the permanent magnet flux in air gaps L1, L2 and opposes that in L3. When the coil 1 is energized in the other direction it assists the P.M. flux in gap L3 and opposes the flux in gaps L1, L2. The magnet 5 acts as two magnets with separate flux paths and the magnetization of its zones 5a, 5b may be varied by use of a demagnetizing electromagnet (Fig. 5, not shown) with its poles placed near the respective zones. Yoke parts 7 extending from the shoe 6 may be at opposite sides of the coil (Fig. 2, not shown) and the magnetic coupling between the zone 9b and the auxiliary armature part 29 may be increased by an additional shoe (Fig. 3, not shown) or by a bent over end of the armature part (Fig. 4, not shown).

Title: Improvements in or relating to electro-magnetic relays
IPC: H01H50/36
Filed: 1930-10-20
Abstract: 361,535. Light current relays. COVENTRY AUTOMATIC TELEPHONES, Ltd. and MYERS, C., of General Electric Co., Stoke, Coventry. Oct. 20, 1930, No. 31373. [Class 38 (v).] In a relay having a plurality of coils with their associated flux paths and a permanent magnet, the flux paths are arranged so that although the armature may be attracted in one direction by any of the coils, variations of the flux through the coil included in the armature flux path caused by variations of current in that coil are not reproduced in the other flux paths. As shown in the Figure, an armature 1 pivoted at 4 to a yoke 3 is adapted to be attracted in the same direction by the energization of a coil 6 or of a coil 2. The latter is mounted on a polepiece of the yoke 3 adjacent the armature and the coil 6 on a cross-limb of the yoke. The two limbs of the yoke being bridged by a permanent magnet 5. Normally the greater part of the flux of the magnet 5 passes through the left-hand branch of the magnetic circuit, including the coil 6 and the polarity of the magnet is such that most of the flux of the coil 2, when energized, passes through the magnet 5. Thus if the coil 6 is shortcircuited and a current started or stopped in coil 2 no appreciable eddy-current effect is produced in the short-circuited coil and consequently no appreciable delay in the armature movement is produced by the short-circuited coil. The armature can be attracted by coil 6 if energized to produce a flux opposing that of the permanent magnet, the permanent magnet flux being this diverted through the path including the armature. Portions of the magnetic circuit may be made of nickel-iron alloy to assist in the reduction of eddy-current effects.

Title: Method of making an electrostatic wire stylus recording head and lead wires therefor
IPC: B41J2/425
Filed: 1971-07-05
Abstract: 1362844 Making electrostatic recording heads; coiling helices VARIAN ASSOCIATES 5 July 1971 [29 July 1970] 31461/71 Headings B3A and B3E [Also in Division B6] A method of making an electrostatic wire stylus recording head and its lead wires comprises providing a receiving surface 62 for the wires and an adhesive for retaining the wires in position on the surface, laying wire 66 on the surface to form a wire member having at least one layer of wires, forming a wire sheet 26 from the wire member and forming a recording head 20 by mounting one end of the sheet 26 in a recording head structure to form the wire styli 18 and leaving the other end of the wire sheet extending from the head structure to form the lead wires. The wire 66 is fed from a spool 68, through a collet 70 and wound on to the surface 62 which comprises an adhesive coated substrate. The collet moves parallel to the winding axis and spray apparatus 72 sprays a colour indicator on the wire at predetermined intervals to facilitate sectioning of the wire sheet and connecting group styli 18 to circuit boards 28. The stylus density is altered by adjusting the speed of traverse of the collet 70. When winding is completed, the wire helix and structure are cut longitudinally and flattened into a wire adhesive sheet (80), Fig. 4 (not shown). A plate 22 with an epoxide surface is placed on the wires dividing the sheet (80) into a major portion (80a), Fig. 5 (not shown), and a minor portion 80b containing any ends which have been displaced during cutting. The substrate is peeled back and a second plate 24 is pressed against the wires opposite the plate 22. The portion (80b) is trimmed off and the edge surface of the plate sandwich is polished to shape. The wire sheet 26 is then separated into sections of convenient numbers as indicated by the coloured wires and terminated on the circuit boards 28. The remainder of the substrate may then be removed if required. Additionally to the adhesive on the substrate, an adhesive may be applied to the wire by an applicator 84a, Fig. 2, or when on the winding drum by an applicator 84c. Adhesive may also be applied directly to the drum by an applicator 84b. By using any or all of the applicators a plurality of layers may be wound on the drum and the multi-layered sheet subsequently formed is mounted between epoxy coated plates. The wire may be multi-stranded to increase the number of turns laid down at the same drum r.p.m.

In a transistor pulse amplifying circuit rectangular positive-going pulses are applied to the base of an NPN transistor TX1 which is normally biased to cut-off by a negative bias over resistor R1, and drive it to saturation. Amplified pulses from the collector circuit are applied to the bases of a number of parallel-connected PNP transistors TX2, each of which is normally biased to cut-off by a. positive bias over an individual resistor R3, again driving them to saturation. To prevent lengthening of the pulses due to charge-storage in the transistors at saturation, they are also applied over a differentiating circuit Cl, R2 to a further PNP transistor TX3 which is normally biased to cut-off by a positive bias over resistor R2. The negative-going "spikes" produced by differentiation from the trailing edges of the incoming pulses drive transistor TX3 conductive to discharge the bases of each of the transistors TX2, via individual diodes Dl, and return these transistors to the cut-off state at the ends of the incoming pulses. To prevent ringing due to stray capacity and caused by the transistor TX3 being still driven by the differentiated pulses when transistors TX2 have returned to cut-off, a conductive path may be provided for its collector current in the shape of diode D2.
