Filed: 1974-08-15
Abstract: 1470875 Watches ETA AG EBAUCHES-FABRIC 15 Aug 1974 [20 Aug 1973] 35952/74 Heading G3T In a watch with jumping digital indicators 15-17 for the tens and units of minutes and the hours respectively each indicator being coupled by a spring to a respective continuously rotated driving member and released at appropriate intervals by a corresponding lever, the lever 46 for tens indicator 15 is actuated by the units indicator 16, the lever 43 for the units indicator is actuated by the units driving member 38, and the lever 53 for hours indicator 17 is actuated by the tens indicator 15. Each lever is pivoted on a display bridge 8 and the digits are displayed through windows 11, 12 in a dial (not shown). A centre wheel 5 revolving once per hour is frictionally coupled to a cannon pinion 4. A tube 33 carries the drive to a tens cannon 28 which drives the indicator 15 via a coupling 29 comprising two parallel plates linked by spring 32. The indicator 15 has teeth 18 and is normally restrained by end 52 of the lever 46. Tongues 49, 50 on the lever engage a cam rib 20 on the underside of indicator 16 so that the lever is lifted every ten minutes and indicator 15 advances under the power of the spring 32. The indicator 16 is itself driven from the cannon 28 via a wheel and pinion 34 and a pinion 36, the latter carrying a disc 38 coupled to the indicator by a spring 39. Five teeth 22 of indicator 16 co-operate with alternate ends of the lever 43 which pivots on a stud 44 and acts as a pallet so that the indicator advances by one half pitch each time the lever is actuated. This is performed by a cam profile 40 on the disc 83, engaging the opposite alternate ends of the lever.  The hours indicator 17 is spring coupled to a member 41 driven by the cannon pinion 4 via a minute wheel and pinion 6. The indicator is normally restrained by engagement of one of its teeth 23 with an arm 57 of lever 53; the lever is lifted hourly when a tongue 19 on indicator 15 acts on lever arm 55. The watch is a calendar watch with date and day indicators 24, 25 arranged below the indicator 17, their indications being displayed between teeth 23 through further dial windows 14, 13.

Abstract: 1,192,659. Stretching. HYDRAULIC G.m.b.H. 30 July, 1968 [8 Sept., 1967], No. 36386/68. Heading B3E. A method for gripping uneven sheets and plates of non-uniform thickness in a stretching and straightening machine is characterized in that the drawing heads 4 are provideid wth a plurality of juxtaposed clamping jaws 1 slidable on wedge surfaces 3 of the drawing heads, the jaws being advanced together as a rigid unit by a power driven crossbeam 7 until they contact the end of the sheet. The drawing heads are moved in the direction of stretching while the clamping jaws slide over the wedge surfaces as they flatten the end of the sheet, the movement of the drawing heads being interrupted upon completion of the flattening operation or upon initiation of the stretching and straightening operation and, with stationary drawing heads, those clamping jaws which, owing to variations in thickness of the sheet, have until then been unable to bite are advanced by their individual drives 9 so that all pairs of clamps grip the sheet effectively.

Convention dates, Dec. 24, 1932 and April 19, 1933. [Class 117.] In apparatus of the type in which granular material to be separated into fine and coarse grades is carried in a primary air current which is intersected by a secondary air current for carrying off the fine product, both currents are set up by a single fan, the primary current being part of the output of the fan and the secondary current being induced by the fan from the atmosphere or forming a part of the return circuit in closed cycle operation. One arrangement is shown in Fig. 1 in which the separator consists of a casing 3 formed with discharge nozzles 3<c>, and connected to a hopper T, in the upper side of which are air-inlets 2. The granular material is fed by a pipe B, and is taken into suspension and delivered in a jet through the nozzles 3<c> by an air current through the pipe 10 in the output circuit of the fan 1. The fan also induces a cross-current through the apertures 2 and inlet pipe 4 to carry off the finer grades of material which are collected in a separator 6, connected by the rising pipe 7 and pipe 9 to the pipe 10. An outlet 8 to the atmosphere and the pipe 9 are provided with valves 8<a>, 9<b> by which the proportions of the primary and secondary air currents can be regulated. The fan may be arranged on the output side of the separator 6 and the apertures 2 may be enclosed in a casing connected to the pipe 8. According to further modifications provision is made for imparting a whirling motion to the primary air-current. Vanes which may be radial, tangential or helical may be disposed in the end of the pipe 10, or the pipe 9 may lead tangentially into a casing connected to the separator 1 by a short pipe contracted at the central portion.

Class 64(1) A fluid-heater section consisting of a tube 8 and two plates 5, 6, between which it is secured, is curved to fit round a flue, chimney or the dry back of a boiler to be mounted on a section of a flue, or to form a section with flanges at the open ends so that a number of sections can be joined end-to-end to form a flue. In either form the tubes 8 of the sections may be connected in series or some in parallel. Pumped water may be passed through the tubes to be heated, and heat insulation may cover the heater. The tubes 8 may be of copper, or like the sheets 5, 6, of aluminium or an alloy thereof. Sheet 5 may be thinner than sheet 6. Flanges 9 at the edges of the sheets are for the securement of tensioning bolts for pulling the heater tightly around a flue or other surface. If the heater sections form a flue wall the tube 8 may be helical and the ridge 7 accommodating the tube may be on the inner surface of the flue. The Provisional Specification describes the device used as an economizer. Specifications 769,929 and 826,625 are referred to.

Title: Improvements relating to rubber compositions
IPC: C08K3/00
Filed: 1930-12-17
Abstract: A cement-rubber composition is made by mixing a concentrated latex or other dispersion of natural or synthetic rubber containing at least 60 per cent of rubber, and an hydraulic cement, the quantity of cement being at least 150 per cent by weight of the liquid content of the dispersion.  The cement may be aluminous, Portland, slag or the like and is of ordinary commercial fineness.  In the case of cements other than aluminous, a stabilizer, other than the ordinary preservative, must be included to prevent premature coagulation of the rubber.  Fillers, vulcanizing agents, accelerators, antioxidizing agents, &c. may be added and also bituminous substances.  The composition may be used in the making of roads, floors, &c., roofs, walls and frames of buildings, pipes, tanks, chemical apparatus such as baths and sinks, and moulded articles such as tiles, slabs and toys.  In an example a road-making composition comprises 208 oz. of concentrated latex containing 152 oz. of rubber, 2 oz. of the stabilizer sold under the trade name Saprotin, 6,4 oz. of sulphur, 3,2 oz. of zinc oxide, 1,6 oz. of the accelerator sold under the trade name Vulcazit 576, 8 oz. of asbestos fibre, 8 oz. of carbon black and 118,4 oz. of alumina cement.  Other examples are given. When making walls, tanks, pipes, &c. a skeleton of the structure may first be made of expanded metal or other meshing, the composition then being plastered on.
