Title: Improvements in or relating to the joining of electrical conductors
IPC: H01R4/10
Filed: 1949-10-12
Abstract: 678,450. Direct connections between conductors. WEST & CO., Ltd., A., BABLER, E. B., and BREEZE, V. L. Oct. 2, 1950 [Oct. 12, 1949], No. 26192/49. Class 38 (i). [Also in Group XXII] A method of joining conductors comprises heating said conductors to a temperature between the recrystallization temperature of the metal and 300‹ C. above said temperature and pressing them together, the temperature and pressure being such that cold welding takes place. In joining together in parallel the ends of silver-coated copper strips laid face to face to form a shunt, the ends are heated to about 400‹ C. and compressed at a pressure of 15-20 tons per square inch. The junctions between the ends of the shunt as a whole and the parts to which they are connected may be made in this way. Similarly the ends of thin wires forming flex may be so joined in parallel. The conductors may be of deoxidized copper if the method is carried out in a reducing atmosphere.

Abstract: 628,374. Centrifugal separators. AKTIEBOLAGET SEPARATOR. Sept. 29, 1947, Nos: 26285, 26286 and 26287. Convention dates, July 27, 1943, May 20, 1944, and May 20, 1944. [Class 23] Starch is liberated from starch-slush, fibres and fruit water in a centrifugal drum 1 by means of radially-adjusted paring or skimming tools 5, 10, which periodically scrape off the layer of starch slush and fibres and then remove the starch. The tools may be controlled by means of electric or hydraulic devices under the influence of a photo-electric cell 19 which reacts to the white surface of the starch when the latter is separated out during centrifuging. Inlet pipes 2, 3, supply starch milk and wash water periodically. A stirrer 4 is attached to the part 5, the combined tool travelling by a carrier on guide-bars 8, 9. The skimming tool 10 is arranged on an arm 12, which swings about a shaft 11, being pressed on a nose 14, of the holder 7, by a spring 13. With the drum rotating, starch milk is supplied through the inlet 2, the members 4, 5, and a scraper 6, occupying their mid-position, Fig. 1. The carrier 7 is then moved in direction a causing the stirrer 4 to enter into operation. A valve 15 is kept closed. Further operations are described in Specification 588,313.

Title: Improvements in or relating to visible-index devices for cards or sheets detachably bound in book form
IPC: B42F21/10
Filed: 1945-10-09
Abstract: 654,044. Indexing. HABERFELD, E.O. Oct. 9, 1945, No. 26296. [Class 16] A device for classifying correspondence &c. comprises a set of sheets or cards detachably bound along one edge in book form and treated so as to form tabs or to interlock with tabs on all four edges of the sheets, the correspondence being placed in the device below the appropriately-tabbed sheet. Sets of sheets may be separated by tabbed record sheets 10. In one form, Fig. 1, each sheet 1 is originally formed with a complete series of index tabs along its four edges. As shown, the tabs 7 on the right-hand edge 3 are cut off leaving only the two corresponding to the first two letters of the matter which is to be placed under that sheet. The tabs 8 on the lower edge 4 may be cut away to leave the one denoting the third letter. Similarly the tabs 6, 9 on the other edges 2, 5 are cut away to leave tabs corresponding for example to the fourth and fifth letters. Alternatively, tabs on the various edges may be used to denote other features such as locality or the type of business. The tabs can be perforated along the edge of the sheet to facilitate their removal. Both the tabs and the adjacent edge of the sheet may be marked with the index references. In another form, Fig. 7, slots are provided adjacent to the four edges of each sheet to receive detachable tabs. At the top edge are two rows of slots 70, 71 and each tab is threaded through two slots, one in each row. The projecting parts 68 of the tabs are inclined obliquely to the sheet edge and in the same direction. At the bottom edge, the tabs are straight and the slots inclined to effect the inclined arrangement of the tabs. At the right-hand edge, alternate pairs of slots are staggered so as to obtain a staggered arrangement of the tabs. These have tongues 72, 72a engaging the slots. Each pair of slots in this arrangement may be spaced from the adjacent pair lengthwise of the sheet or there may be no spacing between them. The reference markings on the sheet may be inclined at 45 degrees to the sheet edge to facilitate reading. Further, the tabs may be of celluloid so that such markings if covered are still visible. Differently coloured tabs may be employed if additional sub-indexing is required. Several forms of tabs are described, those in Fig. 6 being formed by stamping out tongues 30 from the sheet and pushing them through slots 31. The tabs used with slots perpendicular to the sheet edge may have similarlyspaced slots (87, Fig. 12 not shown) in their sheetengaging parts so that intermediate tabs may be placed in position. Specification 624,306 is referred to.

Preferably the damping fluid is silicone putty, known as "bouncing putty". A spring door closer,:Fig. 4, comprises a first member or outer casing 30 with a hollow cylinder 35 located therein and a second member or lever arm 34 which is secured to a shaft 33 connected through a one-way clutch to a shaft 37 on which the rotor 38 is mounted. The periphery of the rotor and the interior of the cylinder are axially serrated or otherwise roughened to engage the silicone putty 39. The clutch is formed by two opposed cup members 45, 46 fixed to the shafts 37, 33, respectively, and a close-coiled spring 47 disposed within the cups to exert a slight outward pressure thereon. In a modification, Fig. 1, the invention is applied to a door hinge, the hollow cylinder 11 being formed integral with one leaf 10 and the rotor 15 comprising a spindle recessed at one end 19 to receive one end of a close-coil spring 20 constituting the one-way clutch as in the previous embodiment. The second leaf (not shown) has hinge knuckles 13, 14, the former containing a fixed cupshaped member 21 receiving the other end of the spring 20 and the latter having a fixed stub pivot 24 for the lower closed end of the cylinder. Bearing sleeves 22, 26 of nylon or similar material are provided. The spindle 15 and the interior of the cylinder 11 are axially grooved or otherwise roughened to project into the silicone putty 17.
