Title: Improvements in or relating to closure devices for preventing the refilling of bottles and the like
IPC: B65D49/06
Filed: 1934-09-14
Abstract: 443,850. Non refillable bottles. CONDE, J. L., 1972, Sgo. del Estero Street, Buenos Aires. Sept. 14, 1934, No. 26444. [Class 125 (i)] In an automatic closure-device for preventing the refilling of bottles or like vessels, of the type described in Specification 419,776, comprising a body 1 which has separate passages 2, 3 for the exit of liquid and the entrance of air and is integral with a valve seat 4 having two openings separated by a transverse wall and adapted to be closed by a single valve member 10 under pressure of a weight 11, the body 1 is provided with two recessed parts 15, to each of which is adhered a thin plate or label 16 of elastic material, the plate being glued to the inner surface of the bottle neck. The upper part of. the body is also provided with two thin bands 19 of elastic material glued to the neck. To prevent extraction of the closure the neck is fitted with a plate 23 formed to correspond to the shape of the neck, and provided with a folded part 24 which reduces the diameter of the bottle-opening.
Patent GB-1011330-A (GB)
Title: Method of producing very fine wires from metals and metal alloys
IPC: B22D11/00
Filed: 1959-07-31
Abstract: Very fine metal wires are made by passing wires or rods of 0.1-8.0 mm. diameter through a metallic, ceramic or cermet nozzle where they are provided with a liquid, plastic or solid sheath (to retain heat and prevent oxidation), heating the wires or rods during or immediately after passage through the nozzle to a temperature above that at which they would normally be hot worked, and drawing them out without the use of dies or the like to at least twice their original length.  A bundle of wires or rods of different materials may be used to form an alloy; other materials may be introduced via the sheath. Heating may be by radiant heat, by resistance heating, or by passing the wires or rods through an arc, and may be enough to melt the metal.  The hot material may be drawn on to a winding drum which may rotate intermittently.  The drawing and subsequent cooling may be adjusted to give the resulting wire desired properties, and the process preferably ends with a cold deformation to increase the tensile strength.

Abstract: 849,492. Snap-action switches; switch contacts, arc-rupturing in switches. SMITH, D. W. C. Dec. 17, 1956 [Sept. 15, 1955], No. 26497/55. Class 38 (5). A switch-fuse unit has fixed contacts 5, 6, 7, 8, the latter two having the fuse 34 mounted between them and being carried between resiliently-mounted insulating parallel bars 3, 4. Two main moving contacts 23 bridge contacts 5, 7 and 6, 8 and are carried between rectilinearlymovable insulating-plates 10, 11 spaced apart by members 12. Each fixed contact 5, 6, 7, 8 is electrically-connected to two members 15, 16 each carrying a roller 18 which acts as an arcing contact. Spindles 26 on which the contacts 23 are mounted have roller arcing contacts 28 at each end arranged so that they engage the fixed rollers 18 before the main contacts close and disengage after the main contacts close. On opening the arcing contacts 18, 28 engage before the main contacts open and open after the main contacts. The resilient mounting for the bars 3, 4 includes springs which urge the bars towards fixed bars 1, 2, which carry contacts 5, 6, so that the contacts are slightly pushed apart during making of the arcing contacts 18, 28. In Figs. 3 and 4 (not shown), the invention is illustrated as applied to a polyphase switch with a snap-action operating mechanism.

Abstract: 1292198 Sputter Etching INTERNATIONAL BUSINESS MACHINES CORP 3 June 1970 [18 June 1969] 26721/70 Headings C7F Sputter etching apparatus comprises a vacuum chamber 10, a pair of electrodes within the chamber, one of which electrodes 12 supports objects S to be etched, means 34 for applying a RF voltage between the electrodes to induce sputter etching of objects S, and trapping means 14 facing and in spaced relation to electrode 12 to receive and hold material removed during etching and reduce re-emission of said material, thereby reducing contamination of objects S. As shown the trapping means 14 may be a series of frustoconical concentric baffles, or it may be inclined or vertical baffles in circular, square, rectangular or parallel configuration, the function of the trapping means relying on geometric-mechanical rather than electrical considerations. The atmosphere may be Ar. In an example, SiO 2  coated Si wafers are coated by phosphosilicate glass, this is etched off in the above apparatus, the SiO 2  is then coated with Si 3 N 4  by sputtering Si in N 2 , and Al dots are evaporated thereon by an electron gun to give a MIS capacitor having superior properties to one made exactly the same way except that the etching was in conventional sputter-etching apparatus.

IPC: A61J1/00
Filed: 1958-08-20
Abstract: 884,078. Medicament containers. BAXTER LABORATORIES Inc. Aug. 20, 1958, No. 26740/58. Class 81(2). A closure cap for medicament container has two projecting spouts at least one of which has a sharp point. When this is applied to the sealing member of a parenteral solution container the medicament can be introduced into the solution container without contamination by surrounding air. The device is primarily intended for use with a solution bottle 10 of the type having an air inlet tube 22. The closure cap 25 for the medicament container 24 has two pointed spouts 28a, 29, the latter of which is of relatively small diameter, so that it can enter into the bore of the air tube 22. This spout 29 is surrounded by a soft rubber sleeve 30 which is compressed between the two stoppers 25, 17 to form an airtight seal and prevent contamination. With the two containers arranged in this way parenteral solution flows through spout 28a to container 24 and mixes with its contents, which may be solid, while displaced air passes up spout 29. The two jars may then be inverted so that the solution flows back into container 10 through tube 29. If the medicament is in liquid form this may be passed directly into container 10 with the latter standing upright.

Abstract: <PICT:0775830/III/1> <PICT:0775830/III/2> <PICT:0775830/III/3> A spray gun from which particles are projected through an electrostatic discharge produced by a high voltage power supply unit having a circuit breaker in its output circuit has a common control device for the projection of the particles and for the operation of the circuit breaker, such that the circuit breaker is operated by the control device to effect an electrostatic discharge when the particles are projected.  A spray gun is connected by a cable 20 to a circuit breaker 18 having a piston 30 movable by compressed air between a discharge stop 34 and contact 28 which completes a circuit through a high voltage supply source 10.  The low voltage coil 60 of a transformer is connected to a relay 54 through normally open contacts 61 and normally closed contacts 62.  The relay is connected to a microswitch 72 of a spray gun which, when the switch is closed by operating the gun, energizes the relay and energizes a solenoid coil 48 of an air valve 42 which supplies compressed air from a source 41 through a pipe 44 to the contact breaker to move the piston to the right and connect the circuit breaker to the high voltage supply. When the switch is opened the lower solenoid coil is energized and the piston is connected to the earthed stop 34.  The gun, Fig. 2 comprises a nozzle 82 supplied with compressed air and spray material through lines 80, 81 by operating a trigger 77 which closes a needle valve 79 and causes a cam 84 on the pivot of the trigger to close the microswitch 72.
