Title: A rechargeable electric battery
IPC: H01M6/42
Filed: 1932-05-07
Abstract: 395,128. Batteries. RATHBONE, G., 39, Percy Street, Northwich, Cheshire, and WYERS, A., 11, Hargreaves Street, Chorltonon-Medlock, Manchester. May 7, 1932, No. 13182. [Class 53.] A battery comprises two cells in series, each cell having a positive electrode of copper and a negative electrode which may be of magnesium in a solution of copper sulphate. A holder is provided for the negative electrodes when the battery is not in use. The positive electrodes consist of closed copper tubes A, B, one of which is provided with a wrapping T of insulating material such as mica, and a screwed terminal rod S. Both tubes are fitted with a loose lining of copper foil to prevent the deposition of metal on the main part of the tubes during the working of the battery. Each tube is closed by an ebonite stopper C having a central opening fitted with a rubber washer E. Attached to the bottom of the stopper is a copper washer F having a central hole the edge of which is sharpened to act as a scraper. The tubes A, B are supported in a metal clamp or holder X to which two additional tubes H are fixed to receive the negative electrodes K when the battery is not in use. When current is required the negative electrodes are pushed through the holes in the stoppers C as shown in Fig. 6. The cells are connected in series by a copper strip O carried by an ebonite plate J. The copper strip has apertures to receive the terminal N2 of the negative electrode of one cell and the terminal rod S of the positive electrode of the other cell. The poles of the battery are constituted by the terminal N1 of one of the negative electrodes, and the clamp or holder X.

Abstract: 1353799 Endless chain conveyers RUDKETTENTABRIK RIEGER & DIETZ 5 May 1971 [20 May 1970] 13256/71 Heading B8A An endless chain conveyer has two parallel chain strands 12 co-operating with vertically mounted sprocket wheels 11, load carriers 13 extending between the two chains 12, the forward end of each carrier 13 being joined by traction pins 14 to the chain strands 12, the carriers being supported in their horizontal journey between the sprockets 11 on upper and lower guide rails 16, 17 by means of rollers 15, 19 at the front and rear thereof respectively, and when the carriers 13 are reversing their direction of movement between the upper and lower rails 16, 17 each carrier 13 is maintained in a horizontal position by the engagement of rollers 20 which are mounted coaxial with the rollers 19 in notches 22 in rotary discs 21 which rotate in synchronism with the sprocket wheels 11. Guide bars 23 which are in the same vertical plane as the guide rails 16, 17 prevent the rollers 20 from falling out of the notches 22 in that part of the path of the carriers 13 by their engagement with the rollers 19, said guide bars 23 being pivotally mounted at 25 to allow said bars to lift up to permit the rollers 15 to pass during the return travel of the load carriers 13 at the lower level. In a second embodiment, Figs. 3-5 (not shown), outer and inner upper guide rails (27, 28) and outer and inner lower guide rails (29, 30) are provided, the outer rails (27, 29) supporting rollers (31, 32) on the load carriers whereas the inner rails (28, 30) support inner rollers (33). The curved guiding bar (34), which supports the inner rollers (33) while the load carriers are passing from their upper to their lower path, are fixedly mounted so that the traction pins (35) at the forward end of each carrier are formed with a bend (36) which allows the said pins to pass along under the guiding bars (34) and under the lower guide rails (30) during the return travel of the load carriers.

[Class 17 (ii)] Connecting uppers to insoles and soles.- In making flexible footwear, a shoe upper provided with a welt is stretched over a last and is secured at the edge of the sole of the last with part of the welt extending outwardly beyond the edge of the last. An outer sole is secured to the projecting part of the welt. The upper may be stretched over the last by tensioning means which engage the upper at the level of the edge of the sole of the last and operate inwardly, part of the upper or welt projecting outwardly beyond the last before or when the sole is applied for attachment of the sole thereto. The tensioning means may comprise a cord system which is passed through the lining of the upper or through the inner loops of a seam which is applied to the upper for this purpose at the level of the edge of the sole of the last. After the shoe is completed this cord system is removed. Alternatively, the upper and lining may be secured together by a seam extending along the edge of the last and the lining is drawn inwardly and secured to a light insole covering the sole of the last. The welt may be of various forms. It may comprise a strip of leather a, Fig. 1, secured by stitches or adhesive to the lower edge of the upper b which need not have a lasting allowance. A seam of stitches g which may also serve to attach it to the upper holds the welt in angular position for the attachment of a sole e. The welt may have an integral or attached extension h, Fig. 2, which may be drawn in and secured to the last c. Or the upper may be secured between the upstanding portion a of the welt and the portion h which is turned upwardly parallel to it. An analogous construction comprises two welt strips superposed and bent into an angular position with the upper secured between the two upstanding portions. The tensioning means for lasting the upper may engage loops of a seam i, Fig. 7, arranged in the space between the upstanding flaps a, h at their lower ends as shown at k.

Abstract: 1,044,351. Illuminated signs. PERTINT Ltd. April 4, 1963 [April 10, 1962: Sept. 4, 1962], Nos. 13773/62 and 33859/62. Heading G5C. In an illuminated display sign in which indicia are carried by a sheet or sheets of transparent glass or plastics illuminated from the edge, the sheet or sheets are notched at 32 so as to be located by the glass envelope of one or more filament lamps 22 whose power is insufficient to melt or discolour the sheet(s). In Fig. 3, grooves 32 fit bulbs 22, whose filaments run parallel to the edge of sheet 4. Figs. 4, 5 (not shown), illustrate two sheets (46), (48) bearing indicia on their rear and front faces respectively, and a contrasting backing sheet (50). The sheets (46), (48) are illuminated by separate bulbs (22a), (22b), fitted with masks (Fig. 5a, not shown), so that each illuminates only one sheet. Edges of sheets not adjacent to the lamps may be painted or covered with metal strip or plastic extrusion to reflect light and embellish the sign. A sheet may comprise a heat-resistant section near the lamp bonded edgewise to a less resistant section, the bond being light conducting. A single sheet may comprise several edgewise abutting parts separated by opaque members and illuminated by different lamps. The plastic may be polymethylmethacrylate. Indicia may be printed on the sheets in opaque, transparent or transluscent ink. The lamps may be mains or battery powered. Fig. 5b (not shown), illustrates a circuit by which one sheet in Fig. 5 may be permanently illuminated, the other switched-on and off by a flasher unit. In a sign using several sheets (Fig. 7, not shown), several light sources may operate intermittently and in predetermined sequence to build up a sign progressively. Adjacent sheets may be illuminated in turn by a single lamp, which may be moved from sheet to sheet, or a moving mask and one fixed lamp may be used.

Title: Process for the production of high molecular weight polyoxymethylene esters and ethers with a definite degree of polymerisation
IPC: C08G2/30
Filed: 1960-04-20
Abstract: Polyoxymethylene esters and ethers having a definite degree of polymerization are prepared by taking a high molecular weight polyoxymethylene diether or diester with a degree of polymerization which corresponds to an inherent viscosity of at least 1,0, measured in 0,5% p-chlorophenol solution at 60 DEG C., and decomposing it to the desired degree by the action of acids in the presence of an etherification agent, e.g. dimethyl sulphite, tetraethyl silicate and alkyl esters of orthoformic acid. Preferred acids are those of the Lewis type, e.g. boron trifluoride and its addition products with ethers.  The reaction may be carried out in excess of the etherification agent or in an inert solvent.  The Specification refers to the preparation of polyoxymethylene diesters and diethers by treating polyoxymethylenes with acid anhydrides or etherification agents.  One such process is described in Example 2.
