Abstract: 571,809. Gear-cutting. GRAF, W. Jan. 31, 1944, No. 1799. Convention date, Jan. 25, 1943. [Class 83 (iii)] In a gear-grinding machine in which the work is given a rolling motion the faces of the gear teeth are flattened as compared with the true involute form by means of a diverting member interposed between the work holder and the means for producing the rolling motion. The longitudinal slide 2 of the machine is fed through a screw 41 driven from a motor 39. An oscillating feeding motion is imported to the transverse slide 3 mounted on the slide 2 by means of an eccentric pin 43 carried by a pulley driven from the motor 39 through a belt 42. The slide 3 carries the work 5 mounted on a mandrel 4 coaxial with and rotated by a shaft 10 carrying an indexing disc 11 and mounted in a hollow shaft 6 carrying a rolling arc 7 with which co-operate tapes 8 fastened to holders 9 mounted on the slide 2. A casing 12 secured to the shaft 6 surrounds the indexing disc and carries a rotatable plug 13 in which is journalled an eccentric shaft 14 carrying a lever arm 15 with a pin 16 adapted to enter the tooth gaps in the disc 11 and a second lever arm 17 urged by a spring 22 into contact with a rotating cam 18 by which the pin 16 is moved into and out of engagement with the disc 11. A lever 23, keyed to the plug 13 carries a roller 24 urged by a spring 38 into contact with a guide segment 25 carrying cam pieces 26 and secured to a ring 27 adjustably mounted within a holder 28 bolted to the slide 3. By altering the size, shape and distance apart of the cam pieces 26, the turning movement of the disc 11 and mandrel 4 due to the rolling motion imparted by the arc 7 and tapes 8 may be modified as desired to give the required tooth form. In a modification, Fig. 11, the arc 7 carries a pin 31 on which is mounted a lever 32 having a roller 35 urged by a spring 37 into contact with the cam pieces 36. A pin 33 carried by the lever 32 directly engages a forked member 34 keyed to the shaft 6.

Filed: 1918-02-01
Abstract: 122,877. Faithfull, W. L. F. Feb. 1, 1918. Stirrup - strap suspenders; fastening.-A safety suspending device for a single strap comprises a member b hinged to a member b<1> removably carried on the saddle-bar c, the member b being provided with a cross-bar b<3> which exerts a wedging grip on the strap a when the rider's foot presses the stirrup downwards. To effect this action, the strap is passed over the lower bar b<6> of the member b and behind the bar b<3>. Should the rider be thrown, the upward motion of the foot restrap draws freely out leases the grip, and the of the suspending device. Adjustment may be effected by pulling the end a<1> of the strap upwards. A stop b<5> is provided to limit the movement of the member b. In a modification, the member b<1> is stirrup-shaped and provided with two eyes to fit on the saddle-bar c. In a further modification, the member b is pivoted on two plates or on one plate provided with a slot, the plates being secured directly to the saddle tree. According to the Provisional Specification, the hinged member may consist of a plate with upper and lower slots for the passage of the strap and a middle slot between which and a corresponding projection on the stirrup bar the strap passes and is gripped by a wedging grip.

Title: A process for increasing the base interchange capacity of glauconite, materials containing glauconite or minerals similar to glauconite
IPC: C01B33/46
Filed: 1927-01-27
Abstract: 265,578. Rosenheim, A. Feb. 4, 1926, [Convention date]. Purifying liquids. - The base interchange capacity of glauconite and similar materials is increased by treating them, prior to their use as water-softening media, in the cold or at a raised temperature, and with or without pressure, with solutions of neutral or alkaline salts, especially salts of the alkali metals or ammonia having an alkaline reaction, for instance, caustic alkalies, carbonates, silicates, phosphates, or borates. Alternatively, solutions of neutral salts, such as sodium chloride or nitrate, or lactates, or acetates may be used at elevated temperatures, e.g. at or above 90‹ C. The salt solution may be passed upwardly or downwardly, or alternately in either direction, through the material, or may be stirred into the latter and then separated therefrom as by centrifugal action. Solutions of different salts may be used successively or mixed solutions be used, and the glauconite may be heated to 150-250‹ C. before or after treatment with the salt solution.
Patent GB-842587-A (GB)
Title: Pigmented composition and methods of making them
IPC: C08J3/22
Filed: 1958-01-24
Abstract: Pigmented polyvinyl chloride compositions are prepared by mixing and heating to a temperature below the melting point of the composition polyvinyl chloride granules with wettable dry powdered pigment and a liquid plasticiser for the polyvinyl chloride which will wet the pigment and be partially absorbed thereby, until the plasticiser is absorbed by both the pigment and the polyvinyl chloride granules, so that the particles of the pigment are dispersed upon and caused to adhere firmly to the surfaces of the granules, the quantity of the plasticiser being less than that which could be absorbed by the polyvinyl chloride granules plus the pigment, whereby the resulting pigmented composition is dry and free-flowing.  Oils not absorbed by the resin, and liquid diluents which volatilize off at the mixing temperature may also be added.  The plasticiser may be di-2-ethylhexyl phthalate, butyl benzyl phthalate, octyl diphenyl phosphate, tricresyl phosphate, didecyl phthalate, n-octyl phthalate, n-decyl phthalate or n-octyl n-decyl phthalate. Specified pigments are Electra Red pigment, channel black, iron oxide and titanium dioxide.  Specified oils are saturated vegetable oils, castor oil, palm oil, liquid hydrocarbon resins, polyalkylene glycols and petroleum oils; and specified diluents are pentane, isopentane, hexane, isohexane and benzene.  The compositions may be formed by adding the plasticiser to the resin-pigment mixture, or by adding a paste of pigment, plasticiser and oil to the resin.  To ensure absorption of the oil by the pigment rather than the resin, the paste may be formed by adding the oil to the pigment and thereafter adding the plasticiser.  The method may be used in the preparation of colour concentrates.

Title: Improvements relating to electric heating elements
IPC: H05B3/36

Abstract: 723,552. Electric heating resistances and panels. COX, D. B. Jan. 30, 1952, No. 2522/52. Class 39 (3) [Also in Group XXXVI]. A low temperature electric heating element comprises a preformed unitary flexible sheet 21 of lead foil less than 0.002 inch thick attached to a backing of insulating material and then formed with slits 25 arranged to provide a narrow elongated tortuous current path, and a slightly thicker piece of flexible metal 27 is secured to the foil and has a supply cable 28 attached thereto, the foil or the foil and backing being enclosed between layers of insulating material e.g. paper adhered thereto. The backing may be a thin flexible insulating sheet attached to or laminated with the foil. The lead may be alloyed with 1-4 per cent of antimony or tin or both, or it may have on both sides a thin coating of tin to facilitate rolling the foil. After mounting the foil on paper, slits 25 are formed in it alternately from opposite sides to form a zig zag path by cutting or by fusing the foil, leaving the paper backing intact. Current is supplied to the opposite ends of the heater by cables 28 soldered to strips 27 of copper or brass 0.003 inch thick secured to the foil by heat and pressure using a suitable flux. Insulating and covering sheets provided with designs are adhered to one or both sides of the heater and are rigid or flexible e.g. of paper, fabric or woven or felted glass fibre. The width of the upper and lower course of the strip may be widened to receive the reinforcing contact strip or tab, which may be secured as in Specification 703,584. Radiant heating panels so formed are used on floors, walls or ceilings. The outer decorated face of the panel may serve as wall paper. The lower end of the panel may extend beneath a baseboard and the upper end beneath a moulding, thus concealing, the supply wires. To form a floor covering, both sides of the panel are coated with an adhesive and attached to tiles or linoleum. The panels may be cemented to the outside of tanks or to containers or equipment, e.g. airborne equipment.

Molybdenum, aluminium, copper and silver are suggested as suitable shield materials and optimum thicknesses are quoted for these and other materials. In order to reduce the power input per unit shield area, the effective area of the shield may be increased by corrugations (Fig. 5, not shown); a plurality of upstanding partitions (Figs. 7-9, not shown); or by inserting a number of perforated metal shields in front of the main shield.
