Patent GB-1218942-A (GB)
Title: Packaging apparatus
Inventor: MYLES MICHAEL JOSEPH
IPC: B65B5/04
Filed: 1968-04-26
Abstract: 1,218,942. Packaging-apparatus. UNION CARBIDE CORP. 26 April, 1968 [28 April, 1967], No. 20006/68. Heading B8C. Apparatus for packaging food items into elastic bags comprises a first cylinder and piston-rod, a receptacle for a food item, one end of which is secured to the cylinder and the other to a ring, three or more fingers pivotably secured at their ends adjacent to and in alignment with the receptacle and arranged to support the bag and a second cylinder and piston for advancing the receptacle and ring into the bag. During the movement into the bag the ring contacts the fingers to expand the bag in advance of the item. The first piston then pushes the food item into the bottom of the bag and the so formed package off the apparatus. Supply of items to the apparatus is controlled by a pneumatic cylinder 44 retracting a gate 42, Fig. 5, to allow a single food item 52 to fall into the receptacle 28. In one embodiment the second pneumatic cylinder 18 pulls the first pneumatic cylinder 22 to the right, Fig. 1, by means of a carriage 14 thereby bringing the receptacle in between two pairs of fingers 34, 35 supporting the bag. The ring 30 spreads the fingers and stretches the bag. The piston 26 of the first cylinder 22 then pushes the item off the receptacle and into the bag and then the packaged item off the apparatus. The lower fingers 35 are held in the rest position by springs. In an alternative embodiment, Fig. 8, the first 64 and second 60 cylinders are fitted inside one another. The second cylinder 60 advances the first by compressed air entering via inlet 68 and when the pressure inside has built up sufficiently, compressed air enters behind the first piston-rod 59 via valve 70 to advance the rod and piston plate 26. The cylinders can be moved relative to the base 12 in order to alter the extent to which the fingers are opened so as to package items of various sizes.

Title: Electric wave signalling
IPC: H03C5/00
Filed: 1936-07-20
Abstract: 475,750. Modulating systems. COOLEY, A. G. July 20, 1936, No. 20125. [Class 40 (v)] A sinusoidal carrier wave is modulated by momentarily varying its amplitude, in accordance with signals, at regularly recurring periods preferably near the peaks and for less than a quarter of a cycle, so that the modulated wave comprises sinusoidal sections of varying amplitude connected by transient sections. The variation of amplitude may occur at each half cycle or a multiple thereof. It is stated that only the carrier frequency need be transmitted, frequencies due to the transient sections being removed by filters. In one arrangement, Fig. 3 (not shown), a modulating valve is supplied with a carrier wave by a rotary generator, the shaft of which carries an interrupter connected in the signal circuit so that the signal is applied to the valve for a moment in each cycle of the generated wave. In the purely electrical arrangement shown in Fig. 5, a carrier wave is supplied over transformer 105 and high resistance 108 to the grid of modulating valve 100. The signals are applied to the modulator over transformer 125 and a valve 130 operating as an interrupter. The normal grid bias of valve 130 is adjusted so that the valve is nonconducting, but momentarily becomes conducting during positive half cycles of a control wave applied to the grid over transformer 145. The frequency of the control wave is that of the carrier or a harmonic thereof and the phase and amplitude of the wave applied to the grid is adjusted by tappings on a resistance 142 connected directly across transformer 145 and a resistance 143 connected across the transformer in series with a condenser. The signal wave impulses are applied across resistance 128 and control the charge on condenser 121 in the input circuit of the modulating valve. The condenser 121 may be replaced by an inductance and the valve 130 may be a gas discharge tube.

Filed: 1920-07-09
Abstract: 148,249. Coninck de Merckem, Baron G. de, (Assignee of Henkart, C. E.). March 14, 1914, [Convention date]. Turning-gear. - A spring starter such as described in Specification 28927/13 is provided with improved means for re-tensioning the spring after use. The starter comprises a rack 8 actuated by a spring 9 and engaging a toothed wheel 15 connected by a freewheel clutch to an extension 16 of the engine shaft. The rack slides in a tubular guide 7 mounted on the front of the car and is connected by a cable 10 passing over a pulley 11 to the spring 9. The rack is held against the tension of the spring by a toothed catch 18, which is withdrawn by means of a lever 23 and control member 24 when the engine is to be started. After starting, the spring is tensioned again by driving the rack from a worm 27 on the shaft 16, which acts through toothed wheels 28, 33 when these are brought into clutching engagement by a cam device actuated by means of a lever 36 and control member 37. When the spring is fully tensioned, the wheels 28, 33 are automatically disengaged by means of a stop on the wheel 33 acting upon the lever 36.

Title: Improvements in or relating to coating of silicone rubber articles
IPC: B05D3/02
Filed: 1955-07-12
Abstract: Silicone rubber articles are coated with a layer of polytetrafluoroethylene resin, and the surface layer of the articles and the resin layer rapidly heated to approximately the fusion point of the resin, and immediately quenched, e.g. in cold water.  The fusion may be effected by subjecting the coated articles to oven temperatures of from 720 DEG  to 800 DEG  F. for maximum periods between 1 1/2 minutes and 30 seconds respectively; or by immersion in liquid baths, as of fused salts, low melting-point alloys or high-boiling-point liquids, when fusion is practically instantaneous; or by high-frequency induction heating.  Quenching may be by immersion in water at about room temperature.  The polytetrafluoroethylene may be applied by dipping, spraying, brushing or the like, preferably using an aqueous dispersion thereof.  The silicone rubbers may be elastomeric polymethylsiloxanes or phenyl methyl polysiloxanes.  The invention may be applied to such articles as sheets, washers, gaskets, diaphragms and packing rings.  In Example (5) the coating with polytetrafluoroethylene of a glass fabric which had been coated and impregnated with silicone rubber is also described.  Specification 776,309 and U.S.A.  Specification 2,448,530 are referred to.

Abstract: 293,808. Pott, A., and Broche, H. July 12, 1927, [Convention date]. Grant of Patent oppcsed. Mineral oils, extracting.-In a process for obtaining benzines, lubricating oils &c. from solid carbonaceous materials in which the materials are first disintegrated by treatment with solvent media boiling above 10‹ C., and the products obtained a:re then converted into the valuable substances required by further heat treatment, e.g. hydrogenation, the first stage is effected at temperatures as high as possible without causing decomposition of the initial material and at pressures corresponding to the vapour pressure of the solvent at the temperatures in question. The disintegration treatment is preferably conducted in stages so that the temperature used in each step lies close to the decomposition temperature of the residual portion of the material. 500 gs. powdered gas carbon are treated with 1000 c.cms. tetraline in four extractions at 320, 350, 380, 400‹ C. Over 70 per cent of the carbon passes into solution and after separation of ash and removal of solvent a pitch-like glittering mass is obtained which melts when heated and is suitable for conversion into benzines &c. Further examples are given of the treatment of caking coals and coal extracts. Specifications 268,372 and 283,545 are referred to.
