Title: Improvements in or relating to expansible stopper devices for use on bottles and thelike
IPC: B65D39/12
Filed: 1933-04-26
Abstract: 399,429. Bottle stoppers. HUNTING, D. M. and HILLING, J. O., 165, New Bond Street, London. April 26, 1933, No. 12214. [Class 125 (iii).] An expansible stopper for bottles &c. comprises a stopper piece B formed or provided with a screw 1 engaging an internallyscrewed plunger member 2, an intermediate member 4 adapted when the stopper is in position to enter into positive engagement with the bottle, said intermediate member having a central bore for the passage of the screw and being provided with a splined portion for the reception of the plunger, means connecting the intermediate member with the screw which permits relative rotation therebetween and also with the plunger but permitting only a limited axial sliding of the plunger, and a resilient washer C between the intermediate member and the plunger. As shown the screw 1 is integral with or secured to a plate 6 screwed to the piece B, the member 4 has a flange 9 from the underside of which project sectors 10 which fit into grooves in the bottle mouth, and the connecting means consist of a screw (not shown) projecting into an annular groove 8, and two screws 17 engaging flats on the plunger.

Title: Electromagnetically-actuated electric switches
Inventor: HAYTER CHARLES EWART
IPC: H01H50/20
Filed: 1956-04-23
Abstract: 817,035. Electromagnetic switches. ROTAX Ltd. July 22, 1957 [April 23, 1956], No. 12311/56. Class 38 (5). The spring-biased contact-operating plunger a is acted upon by two coils e, f connected in series across a supply so that when a control switch k is closed, the current through the coils is not sufficient to operate the switch, but the coil h of a separate relay is also energized to close its contacts g and short-circuit the high-resistance coil f, so that the switch is closed by the coil e. A mechanical coupling (not shown) is arranged, when the contacts c, d are closed, to open an auxiliary switch i against its spring bias, so that the coil h is de-energized and the contacts g open, allowing the windings e and f in series to maintain the switch closed. If the closing voltage is insufficient to operate the relay h, g the current through coils e, f is insufficient to overheat them.

Title: Semiconductor device
IPC: H01L23/06
Filed: 1963-03-28
Abstract: 999,679. Sem-conductor devices. BROWN, BOVERI & CO. Ltd. March 28, 1963 [March 30, 1962], No. 12319/63. Heading H1K. The carrier plate 2 (e.g. of molybdenum) and top electrode 3 (which may be of gold) of a semi-conductor element 1, Fig. 1, are connected with respective terminal elements 4, 5, by layers 10, 11 of a solder which is fluid at the operating temperature of the device. This prevents breakage of the soldered connection which thermal stresses produce when hard solders are employed, allows the use of a thinner carrier plate with improved heat transfer to the terminal element 4 (also acting as a heat sink) and prevents damage to the semi-conductor element by the high temperatures associated with hard soldering. When fluid, the solder layer 11 is retained by capillary forces and by surface tension but when the device is to be subjected to high accelerations the outer edge of the solder is preferably sealed by a layer 12 of silicon lacquer or, as shown in Fig. 2, by a ring 13 of silicon rubber or of lead retained by a groove in the terminal element 5. The carrier plate 2 may be dispensed with and the element 1 soldered directly by the fluid solder to terminal element 4. To prevent the solder from solidifying at high temperatures due to the formation of higher melting temperature alloys or compounds with the material of the adjacent surfaces the latter (electrode 3 and terminal element 4 when the carrier plate 2 is not employed) are preferably covered by layers of molydbdenum, or tungsten with which the solder forms no alloy or compound. The solder may comprise those metals and alloys which are fluid in the range of 30‹ to 130‹ C. Gallium (melting point 29À8‹ C.) is mentioned. Mercury is also stated to be suitable.

Abstract: 592,383. Dobbies. TATTERSALL, T. W. June 26, 1945, No. 12375. [Class 142 (i)] A loom of the kind having a dobby motion for inserting a pattern or heading into the fabric at predetermined intervals, is provided with mechanism for automatically starting the dobby motion, such mechanism comprises a pivoted catch E having teeth e', e<2>, on its lower surface, which is reciprocated over the end of the takeup roller A by links and levers operated from the picking shaft C, and a measuring chain B having one or more, spaced, projections b, each having a pin b<1>, which is carried by a sprocket wheel on the shaft of the take-up roller, each projection b as it travels with the take-up roller being engaged through the pin b<1> by the tooth e<1>. which causes the projection to lift a connecting rod F to the dobby motion to bring the dobby lattice pattern or heading motion into operation. After the tooth e<1> moves out of engagement with the pin b', the second tooth e<2> engages the pin and pushes the projection b away from the connecting rod F thereby allowing the latter to fall back into its initial position leaving the automatically started dobby lattice pattern or heading motion to operate.

Abstract: 623,663. Feeding sheets. BACKHOUSE, H. T. May 9, 1947, No. 12535. [Classes 100 (i) and 100 (ii)] A sheet feeding device in combination with an addressing machine comprises means for supporting two separate stacks of sheets of different kinds, two sheet separating and forwarding mechanisms arranged to separate the sheets singly from the two stacks and feed them to the printing station of the addressing machine and -means for operating the two mechanisms to feed the sheets alternately to the printing station. Sheets are fed alternately from the top of a stack 6 supported on a rising platform and the bottom of a stack 7 which may be of envelopes. From the stack 6 the sheets are separated by oscillating suction grippers 15 actuated by a cam 17 through a link 19, and are forwarded to the printing station of an addressing machine of known type by a cam 22 through a bell crank lever 23. The sheets from the stack 6 are registered by angle plates 14. After printing the sheets are conveyed by suction grippers 12 to a tray 11. Envelopes are separated from the bottom of the stack 7 by suction grippers 30 and are forwarded by grippers 32 operated by cams 33, 34 to the printing station where they are registered by angle plates 13. In a modification sheets are fed along opposed paths from two stacks to a reception station from where they are fed by conveyer tapes to a printing station.

Filed: 1965-03-25
Abstract: Monomers containing a CH2=< group are polymerized in a reaction vessel while introducing into said reaction vessel 1 to 30 parts by weight per hour per 100 parts of monomer of a stream of an aqueous medium containing a dialkyl peroxy dicarbonate or an acyl persulphonate, the line pressure being sufficiently higher than the reactor pressure to ensure positive flow of said stream. Specified monomers are vinyl esters, ketones and ethers, isobutylene, vinyl aromatic and heterocyclic compounds, acrylic and methacrylic esters, amides and nitriles, and vinyl and vinylidene halides.  The polymerization may be an emulsion, suspension or solution polymerization, and the aqueous medium, which is preferably under inert fluid pressure, may contain chain and porosity regulators and suspending agents. Specified initiators are dialkyl peroxydicarbonates and acetyl cyclohexyl persulphonate, which may be dissolved in an inert solvent, e.g. cyclohexane or toluene, or in a copolymerizable monomer, e.g. diethyl maleate.  Apparatus suitable for carrying out the process of the invention is described and illustrated, and examples describe the polymerization in an aqueous medium containing hydroxypropyl methyl cellulose and sorbitan monolaurate of (I and II) vinyl chloride, (IV) vinyl acetate and (V) styrene while introducing an aqueous medium containing diisopropyl peroxydicarbonate dissolved in diethyl maleate; and of (III) vinyl chloride while introducing an aqueous medium containing acetyl cyclohexane persulphonate dissolved in diethyl maleate.
