Title: Improvements relating to clothes wringers
Inventor: SIBBALD FREDERICK ROY
IPC: D06F45/04
Filed: 1954-06-30
Abstract: 778,170. Wringers. HOOVER, Ltd. June 17, 1955 [June 30, 1954], No. 19241/54. Class 138 (2). The bearings 12, 13, 15 for the upper and lower rollers 14 and 16 of a clothes wringer are carried by frame members 10, 11 hinged together about an axis parallel to the axes of the rollers, the hinge pin being constituted by a torsion bar 25 which also forms a spring to urge the frame members together to provide the operating pressure between the rollers. The torsion bar 25 passes through a pair of lugs 26 on the member 10 and a pair of lugs 27 on the member' 11. One end of the torsion bar 25 is keyed to a stressing arm 32 having a forked end 34 engaged by an adjusting bolt 35 threaded into the member 11. The other end 29 of the torsion bar is adapted to be engaged by a detent 41 formed on the lower end of a locking shaft 40 having an operating handle 42. The upper surface 43 of the detent 41 is inclined so that as the shaft 40 is turned to engage the foot with the arm 29 the latter is lifted slightly to transfer pressure from a stop 36 to the upper frame member. The rollers can be released by moving the lever 42 to the left or right from the locked position. A spring 45 biases the frame members apart when they are released. The lower roller 16 is driven through a stub-shaft 18 having driving dogs 19, and a worm gear mounted.in a gear casing 22 provided with a spigot 44 adapted to be mounted on a washing machine. Finger guards 48 at each end cover the space between the frames 10 and 11. Specification 778,169 is referred to.

Abstract: 1,213,397. Reactors. ALLMANNA SVENSKA ELEKTRISKA A.B. 24 April, 1968 [25 April, 1967], No. 19287/68. Heading G6C. A nuclear reactor, in particular of the boiling light water type, comprises a plurality of guide tubes 5 arranged below the reactor core for guiding the cruciform-shaped control rods 7 of the reactor, each guide tube 5 carrying at its upper end a support block 8 for fuel assemblies 4 of the reactor, the blocks 8 being arranged in edge to edge relationship and forming a bottom for the reactor core space. The blocks 8 are each provided with four holes 9, arranged at the corners of a square, for the fuel assemblies 4 and also with a cruciform opening 10 for a control rod 7. Each of the guide tubes 5 is provided with depressions 11 at its upper end so as to conform closely to the shape of the cruciform opening 10 and so that the holes 9 open out on the outside of the guide tube 5. Cooling water passes outside the tubes 5 and through the holes 9 to the inside of the tubular casings of the fuel assemblies 4. Further cooling water passes up the tubes 5 to the openings 10 and over the control rods 7 between the fuel assemblies 4. The guide tubes 5 are detachably connected to leading-in tubes (not shown) for operating rods which connect the control rods 7 to an operating member (not shown). Sealing between the blocks 8 is effected by means of seals 19. Thermal stresses in the core bottom are prevented since the blocks 8 can slide against each other.

Abstract: 1,204,053. Screw-and-nut mechanism; discbrake slack adjusters. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 11 April, 1969 [24 April, 1968], No. 19367/68. Headings F2E and F2Q. A brake slack adjuster comprises a tubular driving member 5 provided with an internal screw-thread 6 engaging a screw-thread 7 on a driven shaft 8, the tubular member 5 being formed on its outer surface with a helical gear 14 which meshes a helical gear-wheel 15 carrying ratchet teeth 20 which are adapted to be engaged by a spring-pressed pawl 21. A pistonrod 4 of a brake cylinder 1 abuts the tubular member 5, and the driven shaft 8 carries a bracket 9 which can be pivotally connected to one lever of the calliper of a disc brake, the other lever being connected to a housing 2. On actuation of the brake, both driving member 5 and driven shaft 8 are moved axially causing rotation of gear-wheel 15. On release of the brake, if excessive slack exists, gear-wheel 15 will be prevented from returning to its original position by the engagement of pawl 21 with the next tooth 20 thereby causing rotation of driving member 5, and hence axial movement, with respect to driven shaft 8. Manual adjustment of the slack may be effected by rotation of a shaft 31, on which gear-wheel 15 is secured, by means of a tool engaging a squared end 30.

Title: Self-Adhesive Dressing
IPC: A61F13/02
Filed: 1967-05-01
Abstract: 1,172,004. Surgical dressings. KENDALL CO. 1 May, 1967 [2 May, 1966], No. 20049/67. Heading A5R. A unitary self-adherent dressing for a wound comprises pressure sensitive adhesive in the form of a discontinuous layer either adherent to one face of an intermediate sheet the other face of which is adjacent an absorbent layer, see Figure 2 (not shown), or directly adherent to an absorbent layer, see Figure 3 (not shown), the adhesive constituting part of the wound-contacting surface of the dressing thereby to provide a surface non-adherent to wounds but adherent to adjacent skin areas. If present in the dressing, the intermediate sheet, which is in a form through which body fluids are able to pass, may be in the form of a film and preferably has apertures therein which are directly opposed to discontinuities in the layer of adhesive, portions of the absorbent layer thus being exposed through the intermediate sheet and layer of adhesive. As illustrated in Figure 4, the dressing 30 comprises an adhesive layer 31 adherent to an intermediate sheet 33 which extends over both major faces and two side edges of an absorbent layer 32 the two end edges of which are uncovered, the adhesive layer and the adjacent major face of the intermediate sheet having coincident apertures 34 therein. As illustrated in Figure 6 (not shown), the exposed surface of the adhesive may be covered by two centrally-overlapping removable protective liner sheets; alternatively, as illustrated in Figure 7 (not shown), the adhesive is covered by one removable protective liner sheet having a projecting unadhered portion to facilitate its removal, the complete dressing being packaged in an envelope sealed at its side edges and transversely to provide peelable seals. The latter package may be sterilized by steam or dry heat sterilization, by chemical gas (for example ethylene oxide) sterilization, or by electron beam sterilization. The adhesive may be a rubber base pressure sensitive adhesive; a polymeric acrylate-containing pressure sensitive adhesive, or a polymeric vinyl ether-containing pressure sensitive adhesive; a suitable composition for each of these three types of adhesive is given in the Specification. The absorbent layer may include a structure which has been non-woven, woven, knitted, netted, foamed, accreted or otherwise formed into an integrated fabric layer; alternatively, the absorbent layer may include non-integrated cellulosic fibres, for example fine fibres of wood pulp. The intermediate sheet, if present in the dressing, may be a smooth integrated perforated sheet of, for example, a polymeric film, a paper or a metallic foil. Apparatus for producing a dressing comprising adhesive layer, perforated intermediate sheet and absorbent layer is described and illustrated in the specification.
