Title: Improvements relating to washing machines
Inventor: LEEK THOMAS
IPC: D06F17/10

Abstract: 760,007. Washing-machines. BURROUGH, F. C. Feb. 5, 1954 [Feb. 7, 1953], No. 3526/53. Class 138 (2). A wall 1 of the tub of a washing-machine or wash boiler has a cylindrical support 3 concentric with a shaft 5 carrying an agitator or impeller, the rear face of the agitator or impeller at a point distant from the periphery being spaced from the wall by the support 3, and the agitator or impeller is of disc-like form with a flat rear face and has a series of flexible ribs, vanes or like projections 11 extending from its front face. These projections are preferably disposed radially and arranged symmetrically about the axis of the agitator or impeller. The invention may be applied to an oscillating agitator at the base of the tub or to a rotating impeller mounted in a side wall or at the base of the tub. A rotary member (not shown) may be provided between the impeller and the support 3, this member being loose on the shaft 5 and being shaped to enshroud the peripheral edge of the impeller. Means may be provided for retarding the free rotation of this member, e.g. it may be pressed resiliently against the support 3. The agitator or impeller may be of rubber or like material and the projections 11 may be integral with it or detachable for renewal purposes. The projections shown are of tapering section and comprise solid portions 11 with apertures 12. The projections may alternatively be unapertured and/or staggered, some being nearer the centre of the disc than others. The impeller may have flat radial ribs with cavities extending thereinto from the back of the disc. The vanes may alternatively be rubber or like tubes or cords secured to the disc by suitable adhesive. The tub may have flat or curved side walls and a semi-cylindrical or hemi-spherical base (Fig. 3, not shown). If the base is semi-cylindrical the impeller axis preferably coincides with the centre of curvature of the base.

Title: Improvements in or relating to hydraulic suspension devices and the like
IPC: F16F9/06
Filed: 1945-02-14
Abstract: 632,496. Hydro-pneumatic shock-absorbers. NEWTON, N. B. Feb. 14, 1945, No. 3672. Drawing to Specification. [Class 108 (iii)] The invention relates to a suspension device of the kind comprising a piston, piston-rod and sealing gland, and a cylinder connected to a displacement space, a resilient cushion exerting a pressure on hydraulic liquid in the displacement space, the arrangement being such that inward movement of the piston relative to the cylinder produces displacement of the liquid against the resilience of the cushion and damping movement of the liquid through controlled passages. According to the invention, the device comprises a second piston located in the displacement space between the liquid and the cushion, means for limiting the outward movement of the second piston under return action of the cushion, an entry port to the periphery of the piston-rod above the gland, and means for connecting the entry port to the cylinder when the piston is in its fully-extended position. The cushion comprises air under pressure above the second piston which is in the form of an annular floating piston 14 (see drawing of Specification 632,497) in the displacement space 13<SP>1</SP> which is connected at its lower end by ports 16 and a valve 17 to the bottom of the cylinder 11. The gland is a high-pressure gland 19 and between this and a low-pressure gland 21 is a fluidholding space 20 connected by a pipe-line 22 to a reservoir 23. The piston-rod 12 is reduced in diameter adjacent the piston 10 at 12b so that when it is fully retracted liquid flows by gravity from the reservoir 23 via space 20 and fills the cylinder 11. In making this adjustment the air pressure in the cushion is first charged through a valve 15 to a predetermined figure and this drives down the floating piston 14 to close the ports 16 when the piston-rod 12 is retracted. The space 20 may be provided with an air-release screw or may be connected to the air space of the reservoir 23 by a second pipeline.

Abstract: 406,127. Vent pegs. MARTIN, D., 49, Tavistock Road, Stratford, London. Feb. 7, 1933, No. 3705. [Class 21.] A vent peg for beer, wine,&c. casks comprises a two-way tap 15 communicating by a channel 16 directly with the atmo - sphere, by a second channel with a valve casing containing a spring- pressed ball valve 21 seating in an adjustable screw cap 24 which admits vent air during emptying of the cask. The channel 16 serves for the egress of froth &c. during the insertion of the vent peg, a rubber tube being attached for this purpose. The liquid may be subsequently returned through the same tube by suction. The ball of the valve may be replaced by a cone or a disc or the gravity valve 30 shown in Fig. 4 may be employed. The rotation of the tap may be restricted by providing a projecting ledge on the body of the peg which is contacted by flats cut on a disk which rotates with the spindle of the tap. The peg may be mounted in the siphon block carrying the usual siphon tube, and to ensure return of overflow without disturbing the sediment in the cask a tube is affixed to the peg reaching nearly to the bottom and provided at its lower end with holes. Specification 260,919, [Class 21, Casks &c.], is referred to in relation to the member 16.

Abstract: 401,640. Aerials. LORENZ AKT.- GES., C., 1, Lorenzweg, Tempelhof, Berlin. Feb. 9, 1932, No. 3891. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 21, 1932]. [Class 40 (v).] Relates to aerial systems designed to produce a, uniform horizontal distribution of energy with minimum space-wave radiation so as to reduce fading effects in broadcast transmission. A central antenna z is surrounded by one or more circles of outer antennµ E, Figs. 3 and 1, the radial spacing x being between one-half and one-fourth of the operating wavelength. An optimum spacing is one-third. The system is energized from a common source S through feed-lines F, as shown in Fig. 2. To maintain a favourable ratio between earthbound and space-wave radiation,.the current in the centre antenna is less than the sum of the currents in the outer radiators. For a wavelength of 300 metres this ratio is preferably three to one. For a wavelength of 400 metres the aerial height may be 60 metres. Each of the antennae may have inherent directional properties. In the arrangement of Fig. 3, the alternate rings of radiators are energized with a phase-displacement of 180‹. An arrangement of horizontal feed-lines with vertically-depending radiators is described as forming " radiation centres."
