Filed: 1956-08-09
Abstract: 797,177. Suction cleaning tools. HOOVER, Ltd. Aug. 9, 1956 [Aug. 22, 1955], No. 24383/56. Class 8(1). In a vacuum cleaner the suction nozzle 11 is attached to a bracket 12 carrying guide wheels 27 and the wand coupling 38 carries bails 34 pivoted on a shaft 29 of load bearing wheels 30 ; the shaft 29 is carried in slots 31 in the bracket 12. The thrust of the wand 42 is taken by the wheels 30 and on a hard surface the nozzle is maintained above the surface by the top 32 of the slot 31 engaging the shaft 29 whilst on carpets the wheels 30 sink into the pile and the nozzle rests on the surface until the bottom 28 of the slot 31 engages the shaft 29 when pressure is applied to the nozzle. The slot 31 may be inclined as shown at 46, Fig. 1. so that forward thrust on the wand causes the nozzle to be lifted. A spring 43 exerts sufficient force on the nozzle to prevent it from tilting when lifted from the floor. In an alternative arrangement, Fig. 3, the rear wheels 54 are carried by arms 51 fixed to the nozzle 11 and links 55 are pivoted to the axles of wheels 53 and load bearing wheels 58 carried by the bail 61 ; a recess 60 engages the axle 56 to limit the downward movement of the nozzle relatively to the loading wheels 58. The nozzle is connected by a flexible tube 40 to the wand 42, and may be fitted with a brush 17.

Abstract: 693,448. Transformers. BRITISH ELECTRIC TRANSFORMER CO., Ltd. Oct. 9, 1951 [Oct. 10, 1950], No. 24733/50. Class 38 (ii). An oil-insulated transformer comprises an oil-tight transformer tank 1 and an auxiliary tank 4 so connected by piping 2, 3 that a continuous body of oil fills the tank 1 and partially fills the auxiliary tank 4, together with a sealing device, such as a simulated " U " tube 7, 8, 9, for maintaining a layer of inert gas between any oil in the auxiliary tank 4 and the atmosphere, the device being vented to the atmosphere and serving to prevent any contact between the inert gas and the atmosphere. The " U " tube comprises two vessels 7. 9 joined near their lower levels by piping 8, the inert gas, such as nitrogen, being located between the level of the liquid in the vessel 7 and the level of the oil in the tank 4. The piping 2, 3 is so dimensioned that convection currents of oil therethrough do not occur, thus the nitrogen does not become heated. An inherent factor of the design is that the volume of liquid in both the vessels 7, 9 and the tank 4 must be at least as great as the volume increase of oil in the tank 1 during operation. A gasoperated relay 5 may be provided.

Patent GB-628090-A (GB)
Title: Improvements in steam pressing irons
IPC: D06F75/18
Filed: 1947-09-10
Abstract: 628,090. Hand irons. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 10, 1947, No. 24885. Convention date, Sept. 11, 1946. [Class 138 (ii)] A steaming iron has a steam generating chamber with a tortuous passage leading therefrom towards the front of the iron, and a water reservoir and a valve at the front with a conduit for conveying water back to the steam generating chamber, the port being so positioned that when the iron is stood on end the port is above the water level. The iron comprises a handle 38 spaced from the body for heat-insulating purposes, a water reservoir 45 having a filler plug 64 screwed into a depending flange 65 so that some air is always trapped in the reservoir and a needle valve 59 controlled by a knob 72. Water passes from the reservoir through a diametrical hole in the plug 49 (not shown) to the needle valve 59, thence through the port 58 in the plug, from which it drips into the base. The base, Fig. 5, comprises a top-plate 26, middle member 20 and sole-plate 2, all secured together. The water passes through the opening 32 in the top-plate, into conduit 30 which slopes down to the rear, through orifice 31 into the steam generating chamber 14 formed in the sole-plate. The sole-plate is heated by an embedded heating element 3 of U-shape which is connected to the terminals 12 and passes under the steam generating chamber 14. Steam passes from the chamber 14, through passage 16 to a second chamber 15 located over the other leg of the heating element, whereby any residual water particles are converted into steam. The steam then passes through the tortuous passage 17, wherein it is superheated, to the front chamber 19, up into the middle member 20 through orifice 24 where it is distributed through the passages 21, 22 to a series of vertical holes 25, down through corresponding holes 25 in the sole-plate and so on to the work. The cavity 81 in the sole-plate houses a thermostaticallycontrolled switch 76, Fig. 1, adjustment being effected by a knob 84 mounted on spindle 82 which passes through a tubular cavity 83 formed in the water reservoir. To prevent the steam creating a back-pressure and so restricting the water feed, provision is made to equalize the pressure in the steam generating chamber and in the water reservoir; thus the plug 49, Fig. 1, has a pair of holes 85 passing axially through it whereby the steam passages are in communication with the air space in the water reservoir. The volume of the trapped air in the water reservoir is such that when the iron is stood on the flats 42, 43 at the rear of the handle, the needle-valve is above the water level so that the supply of steam is automatically stopped. In a modification, Fig. 6, the middle member 20 is dispensed with, water being guided by a sheetmetal scoop 95 to the steam-generating chamber 88, and steam passing through the tortuous passage-way 89 and discharged at the front through orifice 90. Specification. 546,203, [Group XXXVII], is referred to.
