[Also in Division E2] The caliper of a reaction-type disc brake is held in a U-shaped fixed member by springs having a specified shape including transverse portions which engage the caliper and in notches in the fixed member. The U-shaped fixed member shown has legs 4 and 6 on respective sides of the disc and connected by two webs 8 and 2. The two pad assemblies 14 and 16 are held radially in respective portions at 22 and abut the fixed member to take the braking torque. A U-shaped sliding caliper 30 with its pistons (not shown) is held against guide bars 34 by springs (Fig. 2) having a head 42 bearing against the caliper, leg portions 46 passing along the inside of the fixed member and ends 48 retained in slots in the fixed member. The pads may be released for removal by removing the springs and pins 38 to allow the bars 34 to be slid out. An alternative spring (Fig. 4) has legs 63 which pass outside the fixed member, arms 68 which bear on the caliper and a head 62 retained in the slots, as in Fig. 3 (not shown).

Abstract: 274,333. Loos, K., Lehnig, M., Henningr, G., and Dassdorf, R. Nov. 15, 1926. Paints; water-paints; japanning. - Coating compositions adapted to resist chemical influences comprise artificial resin, or materials serving to produce artificial resin, and water glass, with or without silicic acid compounds, and clay or metallic oxides. The coatings are subsequently hardened by heat. In examples the materials to produce artificial resin are more or less reacted with partial or total separation of water, and to 2 parts of such product is added 1 part of a paste consisting of 16 2/3 per cent of water glass, 50 per cent of silicic or metallic oxides, 33 1/3 per cent of silicic acid compounds, and water. The water is sometimes removed before use. In one case when the artificial resin constituents are reacted to the end, a solvent such as alcohol or acetone is used to render the product viscous before adding the paste.

Filed: 1927-10-31
Abstract: 296,591. Koch, F. Oct. 31, 1927. No Patent granted (Sealing fee not paid). Condensers. - Selective wireless receiving apparatus comprises an assemblage of severable variable condensers and means in combination therewith for selecting one of the number for connection to the receiving apparatus so as to form part of the tuned receiving circuit. The fixed plate sets a are mutually insulated and are so arranged in the. frame as to avoid interference and the movable plate sets f are rotatably mounted on a shaft b to which they can be coupled selectively, for tuning purposes, by means not shown. Once a section is tuned to a particular station, it is uncoupled from the shaft b, and that station can always be found again without " searching " by connecting in that section by means of the switch k. The assemblage in Fig. 1 is suitable for five different stations, but this number can be varied. In another form (Fig. 2, not shown), each section of movable plates has its own operating handle, and one section is set aside for selective, as opposed to permanent adjustment.

Abstract: 1481842 Rotary engines; cooling TOWNSEND.ENG CO 1 July 1974 29011/74 Heading F1B An I.C. engine comprises a plurality of cylinders 168, a piston 184 movably mounted in each cylinder and being reciprocable therein, means to supply fuel to the cylinders and means to supply air to the cylinders for a longer time per cycle than the time taken by the power portion of the expansion stroke of the pistons and during a portion of the compression stroke to cool the pistons and the interiors of the cylinders. Fuel is supplied continuously via line 134, Figs. 6, 15 and passes through a tube (108), Fig. 18 (not shown) inside stationary core 30 to jets 118 which inject the fuel through ports 237 formed in a rotor in which the cylinders 168 are mounted. Air passes to the cylinders from a line 66 via bores 76, 78 in core 30 to notches 46, 48 which co-operate with the ports 237 as the rotor rotates. Immediately following injection of fuel and ignition at TDC, the pistons move along the cylinder bores a short distance, corresponding to a portion (235) of cam 18, Fig. 5 (not shown) and then dwell for a time at a constant distance from the port 237, corresponding to portion (234) of cam 18, for combustion to be completed before the main expansion occurs, portion (222) of cam 18, after which the piston remains at its maximum distance from port 237, portion (230) of cam 18, the exhaust ports 182, Fig. 2, being open during the last mentioned part of the cycle to allow purging of the exhaust gas and cooling of the cylinder and piston and cylinder by air entering via ports 237 from the notches 46, 48. Further rotation of the rotor causes the pistons to return along the cylinders closing the exhaust ports and compressing the air charge, corresponding to portion (224) of cam 18. The rotor and core are sealed relative to one another and lubricated by oil supplied via line 52, ducts (54), 56, (58), Fig. 18 (not shown), to grooves 42, 44, Fig. 15.

Title: Phonograph records and methods of making mouldable material for the production thereof and for other purposes
IPC: G11B3/70
Filed: 1935-10-21
Abstract: A synthetic resin is prepared by reacting together resorcinol, formaldehyde and a minor proportion of one of the following: salts of sulphanilic acid, a nitraniline, esters of aminobenzoic acid, nitraminotoluene, and urea.  Resorcinol and the amino-body may be heated in a kettle having heating, cooling, and stirring means, in presence of a solvent, e.g. methyl or ethyl alcohol, until solution is complete and formaldehyde added.  Heating may be continued until a syrup is obtained, and a plasticizer, e.g. turkey red oil, added.  In an example, resorcinol and p-nitraniline are dissolved in methyl alcohol and heated. Formaldehyde is added, when a precipitate is formed which redissolves on further heating and a syrup is formed. More methyl alcohol is added and the solution cooled when turkey red oil and silica are incorporated.  The solution may be applied to a paper or other sheet material or to a fibrous base for making a record disc.  The coated base is dried in air or in a drying tunnel, preferably in a humid atmosphere.  Water or petroleum naphtha may be added to the solution, the presence of the non-solvent for the resin causing precipitation during drying.  The sound record is impressed by heated dies which fuse and harden the resin.  The back of the fibrous base may be coated, e.g. with a nitrocellulose lacquer to prevent curling.  Reference has been directed by the Comptroller to Specification 302,737, [Class 2 (iii)].

Abstract: 745,527. Folding paper; embossing. KINGSBURY COMPONENTS, Ltd. Feb. 18, 1954 [Nov. 18, 1952], No. 29163/52. Classes 100(1) and 100 (2). A buckle-folding machine includes a plurality of rollers and a rotary creasing member located on the discharge side of the fold-forming mechanism, the folded sheets being guided between the last pair of rollers, with which the creasing member co-operates, and the creasing member by a deflector, so that creases transverse to the folds are produced. As shown, sheets to be folded as at 123, 125 (Fig. 8), and creased as at 126 are fed between feed rollers 13, 14 against an adjustable stop 31 of a buckle folder 28. The once folded sheet then passes between a first fold roller 15 and the roller 14 against an adjustable stop 44 of a second buckle folder 37. The twice folded sheet then passes between the roller 15 and a second fold roller 16 and over a deflector surface 113 of a plate 111 pivotally mounted on a shaft 97. Also pivoted on the shaft 97 are crank-arms 101 between the other ends of which is mounted a shaft 102 on which a roller 108 formed with a circumferential ridge 109 is slidably mounted. The ridge 109 co-operates with the second fold roller 16 so that the crease 126 is formed in the folded sheet. By rotating the shaft 97 the roller 108 may be rendered inoperative, the creasing roller 108 being maintained in either operative or inoperative position by a toggle arrangement 103, 104, 105, 106. In a modification (Fig. 9) the plate 47 is removed from the folder 37 and replaced by a plate 47<SP>1</SP> provided with a flange 131 so as to deflect the once-folded sheet directly between the rollers 15 and 16 when only one fold is required. Alternatively a swivelling plate may be provided instead of the flange 131 (Fig. 10, not shown). Instead of a roller 108 the creasing member may be constituted as a spring-loaded arm provided with a smooth, rounded knife edge. Specification 353,156 is referred to.
