Title: Improvements in or relating to electrically-heated containers for beverages
IPC: A47J31/053
Filed: 1952-09-05
Abstract: 728,676. Electric liquid heaters. HOBBS, P. W. Sept. 2, 1953 [Sept. 5, 1952], No. 22429/52. Class 39 (3) [Also in Group XXXVII] An electrically heated container for beverages, e.g. a coffee pot, comprises a ceramic body 1 having an opening in its lower part, a cover, e.g. a brass disc 12 for the opening, an electric heating element 18 ... 20 carried by the disc 12, and means, e.g. nuts 14 and studs 15, for clamping the disc 12 in liquid-tight manner in the opening. The elements 18 .. 20 comprise three parallel plates brazed to the disc 12, the inner plate 19 of which is in circuit so long as the pot is plugged into the supply, the outer plates 18, 20 being controlled by a bimetal strip operating at a predetermined temperature to actuate an "over-centre" switch (see Group XXXVII), in a synthetic resin casing screwed, as at 22, to a metal ring 16 held beneath an inturned flange 2 on the pot 1. A neoprene gasket 13 and an asbestos washer 17 separate respectively the disc 12 and ring 16 from the flange 2. A low voltage lamp 42, shunted by a resistance, is in series with the elements 18, 20.

Title: Cargo handling
IPC: B66F7/02
Filed: 1972-05-12
Abstract: 1386161 Conveyers MITSUBISHI JUKOGYO KK 12 May 1972 [7 June 1971]  22495/72 Heading B8A Cargo handling apparatus which is mounted on a bogie T, comprises a lower conveyer 3, a lift conveyer 2 and an upper conveyer 1 and in operation of the apparatus cargo W is transferred from the lower conveyer 3 to the lift conveyer 2 and then raised to the level of, and transferred to the conveyer 1 via an intermediate conveyer 9 for transfer to the hold of an aircraft, for example. If during the operation of the apparatus cargo cannot be received into the aircraft hold the conveyer 1 is stopped and the succeeding cargo transferred from the lift conveyer 2 can be temporarily retained on the intermediate conveyer 9 by stopping the driving power source of the conveyer 9, while the conveyers 2, 3 remain operative. The lift conveyer 2 comprises endless chains 4-7 which carry flexible cargo-receiving plates 2a. The intermediate conveyer 9 may be located between the lift conveyer 2 and the lower conveyer 3. The intermediate conveyer 9, instead of being endless as shown in Fig. 4, may be a roller conveyer as shown in Figs. 12. If it is desired to retain cargo thereon a stopper 11 is raised thus preventing cargo from passing thereover or alternatively the driving 9c and idler 9b rollers thereof are arranged to be vertically movable relative to each other so that the driving rollers may be moved away from the bottom surface of the cargo.

Title: Improvements in and relating to safety razors
IPC: B26B21/38
Filed: 1934-08-02
Abstract: 428,656. Safety razors. RUUD, O. S., 40, Jacob Aallsgate, Oslo, Norway. Aug. 2, 1934, No. 22585. Convention date, June 4. [Class 30] [See also Group XXVI] The blade 7 is reciprocated by the power of a helical torsion-spring 29, which drives through multiplier gearing 17-13, a three-sided cam 6, directly engaging either a hole in the blade or in a slide 4, moving with and above the blade. The driving spring 29 surrounds a tube 31 carrying loose bushes 32 which prevent binding and overwinding. It is wound up by turning a lower handlesection 26, secured to a tube 27, rotatably retained inside an upper handle-section 25, and secured to the upper end of the spring 29. A smaller coil-spring 30 is also secured thereto and coacts with the handle-section 25 to form a ratchet. detent, preventing unwinding of the spring 29 at its upper end. To the lower end 10 of the cam-driving shaft 9 is secured an arm 20, carrying, on arcuate blade-springs, centrifugal braking masses, Fig. 3, (not shown), which co-operate frictionally with the interior of the handle to limit the speed. A screw 24 is used for stopping the blade when required. The slide 4 carries guides 5, and an antifriction plate 1a may be arranged beneath the blade. When the slide 4 is not provided, the guard 1 carries the guides. The cover-plate 2 is secured to the guard by end-clips 3, and the blade has three rectangular holes.

Title: Apparatus for applying fusible or liquid dyes to workpieces
IPC: B05C5/02
Filed: 1975-05-23
Abstract: 1454709 Apparatus for dyeing H GIERSE 23 May 1975 [24 July 1974] 22593/75 Heading D1L Apparatus for applying fusible or liquid dyes, preferably wax-bound dyes, to the cut edges of leather or substitute leathers comprises, as shown in Fig. 1, two sealed reservoirs 2 and 3 for different dyes 4 and 5 which are melted by heating rods 6, a vacuum pump 28 connected by means of connection 11 to the spaces over the dyes in reservoirs 2 and 3 and outlet devices 15 and 16 fed with dye through feed channels 31 and 32 for applying dye to the cut edge of workpiece 26. Control of the vacuum and of the temperature permits the rate of application of dye to a workpiece to be regulated. The outlet devices 15 and 16 remain continuously open whilst the apparatus is in operation and the outlets are formed by interstitial gaps between stacked laminations 17, the cover plates 24 and 25 serving to locate the workpiece.

Title: Metal bodies filled with substance to provide solid bodies
IPC: B21D9/15
Filed: 1936-08-17
Abstract: 485,639. Making composite wheelrims, rods, furniture, and vehicle frames. TECHNIK AKT.-GES. Aug. 17, 1936, No. 22617. Void. Convention date, Sept. 17, 1935. [Classes 83 (ii) and 83 (iv)] Fillings.-A light hollow metal body is filled with a plastic mass adapted to harden and increase the strength of the metal body, the body being shaped as by rolling or pressing after insertion of the mass but before solidification. A tube a is filled with a mass b consisting of sawdust and waterproof glue, and is rolled to form a wheel rim, the mass b then being hardened in a drying chamber. One end of the tube is closed during rolling by a plug d of a cross-section corresponding to that required in the finished article. The other end is closed by a plug which is afterwards removed and the plug d also inserted in this end. Spoke nipple holes are drilled after solidification. The invention is also applicable to the production of frames and ribs for vehicles, spars, and parts of furniture.
Patent GB-831276-A (GB)
Title: Improvements in or relating to steam boilers
IPC: F22G5/16
Filed: 1956-07-20
Abstract: 831,276. Feedwater heating systems. KULJIAN, H. A., and FADDEN, W. J. July 20, 1956 [Aug. 24, 1955], No. 22623/56. Class 64(1) Apparatus for heating boiler feed water includes a direct-contact multi-stage heater 1 to 5, a receiver 6, a pump (not shown) for delivering condensate from the receiver to the boiler, and means for delivering high-pressure steam to the receiver to pressurize the condensate and thus reduce the power requirements of the pump. Condensate enters the heater 1 through a valve 12 which is automatically operated in response to changes in the level of condensate in the heater, condensate being returned by a pipe 18 to the condenser or a storage tank when the level reaches a preselected position. Lowest. temperature extraction steam from the prime mover flows into the heater through a pipe 26 and mixes with the condensate which spills over trays 24 and collects in a chamber 30 connected to the heater by a valve 36 and a valve 36a which vents residual steam and air from the chamber 30. When the condensate in the chamber 30 reaches a predetermined level a device 46 automatically reverses the valves 36, 36a so that chamber 30 discharges condensate to the heater 2 while a chamber 32 receives condensate from the heater 1. The heater 2 is supplied with extraction steam at a higher pressure than that supplied to chamber 1 and the chamber 30 is connected to it by the valve 36a so that the pressures are equalized and the condensate discharges under gravity. A second device 46a again automatically reverses the valves 36, 36a when the chamber 32 has been filled to a predetermined level. The condensate passes in the manner described through each of the heaters in turn until it reaches the receiver 6 which has a heating coil 78 supplied by a pipe 80 with the highest temperature extraction steam. This steam is de-superheated in the coil 78 and flows through a pipe 82 to the heater 5. Boiler steam from a pipe 84 pressurizes the receiver 6 and also passes alternately to the condenstate transfer chambers 30a and 32a. Heater 2 includes de-aerating or scrubbing trays 24b and is connected by valves 62, 68 to a condensate storage tank, the valves being operated automatically at predetermined liquid levels in the heater. Heaters 2 to 5 each include a device which automatically controls the rate of now through the corresponding valve 36 in dependence on the quantity of condensate in the heater while all of the heaters are provided with a safety valve 86.
