Filed: 1966-08-22
Abstract: 1,147,161. Pneumatic despatch apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 22 Aug., 1966 [24 Sept., 1965; 1 Oct., 1965], No. 37516/66. Heading B8A. [Also in Division G4] In an information storage system an input/ output terminal 16, Fig. 1 is connected by way of a main pneumatic conveying channel 11, 13. 15 to buffers 4, 5, 6 each associated with a respective file 1-3. The files 1-3 comprise a matrix of storage cells each containing a carrier which holds a plurality of film chips which may have additional magnetic recording thereon. Each buffer 4-6 is capable of extracting a carrier from the associated file by means of an accessing system, e.g. as disclosed in Specification 1,121,957, and while extracting (or returning) a carrier provides a through channel aligned with the main channel so as not to interfere with the transport of other carriers to and from terminal 16. Each buffer is also capable of transferring an extracted carrier to the I/O terminal 16 and of returning the carrier from terminal 16 to the buffer and thence to the file, the pneumatic supply for extracting or refilling or transporting a carrier along the main channel being applied through the appropriate buffers. The terminal 16 may be a reproducing station, e.g. for recording on aperture cards, or for reproducing information stored on aperture cards on the film chips. Each buffer comprises an air - tight compartment, Fig. 11, containing two tubes 309, 323 coupled to shaft 347. In the position shown, tube 323, which has apertures 314 communicating with the airtight container, is aligned with a file input/output tube 302, so that by connecting the vacuum or pressure side of a blower to the airtight container, a carrier may be extracted from or returned to the associated file by way of tube 302. In this position, tube 309 provides a sealed connection between main transport tube sections 305, 306. By rotating shaft 347 through 90 degrees, tube 323 is aligned with sections 305, 306 so that a carrier may be ejected from tube 323 into the main channel. In this position, flaps (not shown) seal the sections 302, 305 leading to the file and other buffers, respectively. The carrier is returned from the I/O terminal by applying vacuum to the airtight compartment, the carrier automatically coming to rest in tube 323 since the vacuum is applied through apertures 314. By rotating tubes 309, 323 back to the position shown, the returned carrier may be refiled. Switches 351, 352 sense the position of shaft 347 and photo-cells 360, 361 sense the presence of a carrier in, or the passage of a carrier through tubes 323, 309.

Title: Ambient temperature compensated electrical switch
IPC: H01H71/16
Filed: 1956-12-13
Abstract: 808,962. Thermal switches; snap-action switches. SQUARE D CO. Dec. 13, 1956 [Jan. 9,1956], No. 38079/56. Class 38 (5). In an overload-protection switch, a U-shaped bi-metal heated by passage of the load current, a U-shaped ambient-temperature-compensating bi-metal and a pair of longitudinally extending connecting rods are arranged in a substantially longitudinally extending manner between an abutment and an operating arm for the switch contacts. Fig. 3 shows an overload relay which opens contacts 19, 21 connected to terminals 15, 16 when an overload current passes through a heater 49 via main terminals 47, 48. Passage of the load current through the heater 49 causes one arm 35 of a floatingly mounted U-shaped bimetal to move a slidable rod 29, the other arm 37 of the bi-metal resting against an adjustable abutment 38. A shoulder on the rod 29 moves one arm 28 of a floatingly mounted, ambienttemperature-compensating bi-metal 27 and the other arm 26 of the bi-metal presses an operating rod 23 against a switching arm 17 carrying the contact 19. Overload current through the heater causes the rod 23 to press hard enough to actuate an over-centre acting resilient link 18 which opens the contacts 19, 21. The contacts 19, 21 are reset by downward movement of a plate 7 which rotates a shaft 53 through 90 degrees. This causes a part 57 of the shaft to press against the switching arm 17 and close the contacts. The plate 7 may be pinned down and the shaft 53 therefore permanently turned through 90 degrees to provide automatic resetting. In another form, Fig. 8 (not shown), the relative position of the bi-metals is reversed, i.e. the ambient-temperature-compensating bimetal is nearer the abutment 38.

Title: Improvements in or relating to pressurised fluid-cooled nuclear reactors
Inventor: WILSON JOHN HENRY
IPC: G21C13/00
Filed: 1960-11-08
Abstract: 917,606. Nuclear reactors. SIMON-CARVES Ltd., and GENERAL ELECTRIC CO. Ltd. Nov. 2, 1961 [Nov. 8, 1960], No. 38328/60. Class 39 (4). A pressurized fluid-cooled nuclear reactor in which the reactor core is housed within a concrete pressure vessel whose inner surface is adapted to be cooled by coolant flowing in heat exchange relationship with the surface independently of the main reactor coolant. The reactor comprises a graphite core 1 within a concrete pressure vessel 3. Pressurized coolant gas enters the core through the ducts 4, flows through the vertical fuel elements, and is exhausted by way of ducts 5 to four heat exchangers (not shown). Access to the core is provided by standpipes 7, while further standpipes (not shown) are placed at the side of the reactor to enable samples of gas to be extracted for monitoring purposes. The whole of the inner surface of the vessel 3 is lined with a gasimpervious steel membrane 9, and spaced from this membrane, forming an annulus, is another steel membrane 14 constituting a heat insulator. Heat is removed from the walls of the vessel by three primary circuits each of which is provided with auxiliary circuits. In the first circuit gas enters the vessel through six inlets 17 and passes up the sides of the vessel in the annular space between the membranes 9 and 14. At the crown of the vessel the gas is guided radially inwards and is extracted through twelve nozzles (not shown) disposed between the standpipes 7 in two circular patterns. The main reactor and coolant pressures are equalized by providing small holes 22 in the membrane 14, however interchange of gases is discouraged by placing screens 23 in front of the holes. Gas entering the pipe 24 and leaving the pipe 27 provides a parallel auxiliary coolant circuit for the duct 5. The second primary circuit, which cools the bottom of the vessel and the ducts 4, enters the space between the membranes through the pipe 28, is guided by baffles 29 and leaves through the pipe 30. Again the membrane 14 is provided with holes to equalise the adjacent pressures. Parallel auxiliary circuits cool the ducts 4, inlet pipes 32 and outlet pipes 33 being used for this purpose. The third primary circuit cools the standpipes 7 by allowing the coolant gas to flow in the annulus formed between the standpipe and its sleeve. The standpipes are arranged in groups of eight, the coolant of those in the same group flows in series, while that of different groups flows in parallel and is connected to headers 41 and 42. The pressure of this circuit is less than the reactor coolant so that contamination of the latter is avoided.

Filed: 1968-08-10
Abstract: 1,243,395. Change-speed control. F. FALCIAI, R. FALCIAI, and R. FALCIAI. 10 Aug., 1968 [12 Aug., 1967], No. 38328/68. Heading F2D. A servomotor which steplessly varies the gear ratio of a motor vehicle drive is controlled by a mechanism whose operation is dependent upon the relative movement of the fuel regulator and a centrifugal speed sensor of the engine. As shown, movable members 1 and 2 are connected to a fuel regulator 3 and an engine speed sensor 4 respectively for movement longitudinally of and parallel to each other. An electrically conductive extension 5 of the member 2 is adapted to engage a contact 6 connected to a resistance winding 8 or a contact 7 connected to a winding 9. When an accelerator connected to the movable member 1 is depressed the member 1 is moved upwardly and the extension 5 engages the resistance 9 before engaging the contact 7. The servomotor is thus energized in a direction such that the gear ratio of the drive is increased and the engine speed increases. Consequentially the member 2 moves upwardly, the servomotor is reversed and the gear ratio is decreased. Following the completion of these changes, the ratio of the rate of fuel feed to the engine speed is substantially the same as the initial value. A system of springs 13, 15, 16 ensures that there is satisfactory idling of the engine when the vehicle is stationary. In place of an electric servomotor an hydraulic motor controlled by hydraulic means associated with the members 1, 2 may be used.

Title: Improvements in increasing the particle size of synthetic rubber latices
IPC: C08C1/065
Filed: 1958-11-28
Abstract: The particle size is increased in a synthetic rubber latex, obtained by the emulsion polymerization of a conjugated diolefine which may be mixed with up to 70% based on the mixture of an aryl olefine, by freezing and thawing, the latex containing 20-45% by weight of solids and 3-100 parts by weight per 100 parts of rubber of the diolefine and/or aryl olefine monomer.  The diolefine may be butadiene, isoprene, 2, 3-dimethylbutadiene or piperylene; the aryl olefine may be styrene, alpha-methyl styrene, vinyl toluene, parachlorostyrene, and dichlorostyrenes. Butadiene-styrene copolymer latices having particle sizes of 300-1000 A are preferred.  The polymer mix is usually shortstopped after 50-95% conversion by addition of 0,05-1 part (per 100 parts of monomer) of potassium dimethyldithiocarbonate, hydroquinone or dinitrochlorobenzene.  Some or all of the excess monomers may be removed before freezing, in which case additional monomer is then added.  Preferably the latex is not kept frozen for more than 15 minutes or cooled below-10 DEG F.  Alkali metal soap and/or hydroxide may be added to stabilise the latex.  Residual monomers may be stripped after the freezing and thawing operation.
