Title: An improved fitting appliance for hats
IPC: A42C3/00
Filed: 1928-06-01
Abstract: 311,123. Booth, W. June 1, 1928. Fitting appliances.-A fitting appliance for hats comprises a hollow non-adjustable conical member 1 which is heated internally, and radiallyslidable cone sectors 11 provided externally of the conical member and adapted to be separately adjustable towards and away from the conical member, whereby the conical member by pressure of the hat thereonto with the sectors in their innermost positions serves to ease the hat irrespective of its size, and the sectors serve, on displacement from their innermost positions, to change the length or width of the head opening of the hat under the action of heat thereon. The appliance may be heated by a carbon filament electric lamp 30. The sectors 11 may be drawn outwards by screws 18 operated by swivel handles 20 or by handles directly attached to the sectors. Return springs may be provided. Preferably, the conical member 1 is recessed to accommodate the sectors when in their innermost positions. For use with the appliance, a metal ring 47, in two halves connected by rivets engaging slots 51, 53 is provided. This ring is placed between the hat and the appliance to prevent denting of the hat band.

Filed: 1951-07-09
Abstract: 698,571. Joint-making packing; stuffing-box substitutes. AEROQUIP CORPORATION. July 9, 1951, No. 16262/51. Classes 122(iii) and 122(v) [Also in Groups XXVIII and XXIX] Sealing means applied to valve closure members for a self-sealing pipe coupling (see Group XXVIII) consists of a layer of rubber or like resilient material retained under pressure between a pair of outer metal &c. parts and protruding at its edge to an extent corresponding to the inherent flow of the rubber &c. after its edge has been machined flush with the edges of the metal parts. With the rubber &c. of 0.010 inch thickness the protrusion is of the order of 0.001 inch. An outer part or ring 18, Fig. II, is contracted on to the tubular, resilient layer 16 by the pressing over the assembly of. a sizing or contracting ring. A ring 28, in the form shown in Fig. III, is expanded against the resilient layer 26 by the forcing of a ball through the bore 22. The subsequent machining of the closure surface, either to a chamfered form as shown or to a plane surface, leaves the edge of the resilient member protruding slightly. The invention is also applicable to a straight sealing edge in which the resilient layer is held between two flat plates.

Title: Improvements in or relating to the production of heavy water
IPC: C01B5/02
Filed: 1956-05-25
Abstract: 837,894. Electrolytic production of heavy water. JUNTA DE ENERGIA NUCLEAR. May 25, 1956 [June 1, 1955], No. 16328/56. Class 41. In the production of heavy water by a cascade system of groups of electrolytic cells, a first group of cells is fed with natural water and the water-vapour which is entrained with the electrolytically evolved hydrogen and oxygen is separated in separate condensers in the hydrogen and oxygen lines and constitutes the feed of the following group, the feed of the succeeding groups being obtained similarly, and the hydrogen leaving (a) the second and subsequent groups of cells; or (b) the third and subsequent groups of cells, after having been deprived of the bulk of the water-vapour entrained, is fed to a reactor wherein by means of a catalyst it reacts with water-vapour having the deuterium content of natural water to produce a hydrogen with a smaller deuterium content and a vapour enriched in heavy water, which vapour is fed to the preceding group of cells. As shown, the first cell group 1A is fed at F with natural water and the evolved hydrogen (shown by chain line) and oxygen are freed from water vapour in condensers B and the condensate fed to cell group 2A, a similar series of steps occurring in cell groups 2A to nA. The hydrogen from cell group 3A (procedure (b) above) after condensation of the water vapour is fed to an isotope exchange reactor C where its deuterium content is removed as D 2 O by interchange with water vapour fed into the reactor at G, the resulting water vapour being condensed at B<SP>1</SP> and used to supplement the feed to the cell 2A. Similar procedures are followed in cell groups 4A to nA except that the hydrogen issuing from the condenser following the reactor is mixed with that evolved in the preceding cell group. The water vapour condensate from cell group nA constitutes the output of the plant. The hydrogen leaving the plant is collected for use elsewhere. In procedure (a) above, the cell group 1A is omitted and the first cell group is group 2A. In a modification (Fig. 2, not shown) the hydrogen evolved from cell groups 3A to nA after removal of water vapour is subjected in the line from each cell group an isotope interchange reaction and condensation procedure two or more times, the condensates being combined for feeding to the preceding cell group.

Filed: 1938-06-03
Abstract: 518,816. Throat microphones. BALLANTINE, S. June 3, 1938, No. 16698. [Class 40(iv)] A throat microphone utilizes the piezoelectric effect, two microphones being preferably carried by a band adapted to be worn round the neck. The wall 1 enclosing the two microphones is of glove leather &c., and may be covered with thin rubber or leather 4 passing over buttons 5 which convey the throat vibrations to the crystal units 7. The units 7 are mounted between members 8, 9 of rubber, leather, or synthetic resin. The buttons 5 of balsa wood or white pine are cemented to the crystal and are secured to metal stirrups 10 which embrace the crystal unit. Metallic inserts 16 pass through the wall 1 and serve to earth the wearer. The frequency characteristic of the microphone at the higher frequencies is improved by making the casing 11 robust, and dimensioning and clamping the crystals so that they have a high natural frequency. Damping of the crystals may be effected by the members 8, 9 or by inserting pieces of damping material, such as oiled felt or rubber, between the crystal and its housing, Fig. 13 (not shown). A stop 7<SP>1</SP>, Fig. 6, prevents excessive bending of the crystal. Connections to the crystal unit are made through a cable having a central conductor and concentric sheath. Specifications 518,814 and 518,815 are referred to.
