Title: Improvements in the manufacture of fabric belting
Inventor: FRY SYDNEY
IPC: F16G1/04
Filed: 1950-07-04
Abstract: In the manufacture of fabrics for use, for example, as belting, the fibres or yarns, particularly warp yarns, prior to incorporation into the fabric, are treated with a liquid suspension or dispersion of an un-gelled polyvinyl compound together with a plasticizer therefor, and the treated fibres or yarns are formed into a fabric which is then subjected to a heat treatment to gel the polyvinyl compound. Specified polyvinyl compounds are polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyacrylonitrile and mixtures and copolymers thereof.  An aqueous emulsion of the polymer and plasticizer or a suspension of the polymer in a liquid plasticizer may be employed. The heat treatment may be combined with the application of pressure and/or tension to the fabric.  The fabric may be given an additional surface coating of a polyvinyl compound before or after the heat treatment.  The fabric may be made of any yarns, e.g. cotton, asbestos, rayon, wool or hair yarns.

Filed: 1927-06-23
Abstract: 297,160. Hofmann, J. W. June 23, 1927. Drawings to Specification. Clamps for cables.-The parts of a clamp for suspending or straining electric cables which are in contact with the conductor are made of the same metal as the conductor, while the other parts are made of iron or steel. Corrosion between the clamp and the conductor due to electrolytic action is prevented, while the use of iron or steel enables the weight of the clamp to be reduced. Instead of using the same metal as the conductor, a metal near to it in the series of potential differences may be used. Specification 297,159 is referred to.

Abstract: 236,924. Bicheroux, M., (Assignee of Michaelis, K.). July 10, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Annealing-furnaces.-Relates to the method of annealing plate glass in which the plates, as they leave the rolling apparatus, are passed through a series of annealing and cooling chambers before they enter the leer. According to the invention, the movement of the table B. on which a plate K is received from the rolling apparatus A, carries it into the first of the annealing chambers D. The plate is thus carried into the chamber as it is formed and suffers a minimum of cooling in order to avoid loss of heat from the chamber it is formed with a movable bottom C which moves out of the chamber as the table B is moved into it. The two tables B, C may be combined to form a single table. After the plate has arrived at a proper temperature, it is pushed through a slot I into the next chamber and the table is drawn back to receive a new plate.

[Classes 35 and 38 (iv)] To stabilize the D.C. excitation of any electromagnetic device, e.g. a dynamo-electric machine or a magnetic amplifier, an auxiliary winding 14 energized from an auxiliary source 15 is connected across the supply source 13 with the E.M.F's of the two sources in opposition with respect to the auxiliary winding 14, which assists or opposes the main winding 11 according as the source voltage is lower or higher than that of the auxiliary source. Further auxiliary windings, such as 18, each energized from a separate source, such as 19, may be similarly arranged and the last source may be a standard cell. The main supply may be rectified current and may charge the auxiliary source ; any harmonics in the rectifier output would be cancelled by the respective windings. The windings preferably have the same ohmic resistance per turn. A signalling device 17 in the circuit of the first auxiliary winding 14 may indicate a current exceeding a predetermined value.

Abstract: 679,480. Potato planters. SMITS, C. T. June 27, 1949 [June 26, 1948; Oct. 25, 1948], No. 16994/49 and 16995/49. Class 6(i) A potato planting machine comprises rotatable arms 7 fixed on a shaft 6<SP>1</SP>, each being provided with a needle 10 for picking up a potato from a hopper 33 which is supplied with potatoes from a main hopper and a vibrating conveyer. The needle is mounted on a double armed lever 12 and the potato is removed from the needle by a spring urged pivoted lever 40. A resilient cam projects into the path of the arm and moves the lever 40 to eject the potato. Each hopper 33 is provided with an opening 11 and a spring urged sliding container 44 is provided beneath the opening and is connected to a lever 20 by a link 24. The lever 20 is attached to a bush 19 rotatable on the shaft 6<SP>1</SP> and having a notch 18 therein. Each arm 7 contains a spring urged member 15 having a roller 16 and a cam 14 which engages the end of the lever 12. Rotation of the arm 7 causes the roller 16 to follow the periphery of the bush 19. When a potato is picked up by the needle it depresses the end of lever 12 which engages the cam 14 of member 15 and prevents movement thereof. If the needle fails to pick up a potato, the roller 16 drops into the notch 18 causing movement of the lever 20 which moves the container discharging a potato down a shoot 21. On a complete revolution of the arm 7 the container 44 abuts against a wall 46 of the shoot 21 disengaging the roller 16 from the notch 18. Various modifications of the means for ensuring an even delivery of potatoes are described wherein the container 44 is replaced by arms having needles similar to the arms 7. The member 15 is replaced by a spring urged tube which surrounds the arm 7 and is locked in place when the needle picks up a potato by the lower end of the needle which projects beyond the arm 7, and engages in a slot in the tube. The needle may be held in place so that the lower end may move to project beyond the arm 7 when required, by spring, friction or magnetic means.

To prevent the cutter bar from being lowered during the transport of the machine the lever 9 may be held in position by a locking pin. The lever 9 is also used to swing a pivoted stand 18 into position to hold the draw bar pole elevated for connection to the tractor, a connecting link 17 being attached to the lever for this purpose.

The chambers 12, 16 are isolated from the outside atmosphere except for the usual amount of the leakage inherent in the structure, the slots 11, 19 being only just wide enough for the strip to pass through. The cooled strip then passes between pinch rollers 20, through a pickling bath 21 and a washing bath 22, thence to a brusher 23, a wiper 24 and an. electric dryer 25 before it is wound up on a reel 26. If stainless steel of the 18-8 varietv is being annealed, a small amount of air may be admitted to the chambers 12, 16.

Title: Improved manufacture of ammonium salts
IPC: C01C1/242
Filed: 1928-06-13
Abstract: 292,129. Montecatini Soc. GÚnÚrale per l'Industria Mineraria ed Agricola. June 14, 1927, [Convention date]. Ammonium sulphate and other salts are prepared by spraying or atomizing on acid such as sulphuric acid into an atmosphere of ammonia. The concentration of the acid is selected so that the heat of the reaction vaporizes the water and leaves a dry salt. A reaction chamber A containing ammonia is supplied with acid through an atomizer B. The gaseous contents of the chamber A are circulated by a fan D upwards through a rectification column E and cooler F, which condenses the water vapours. The chamber A is supplied with ammonia either by supplying aqueous ammonia through a pipe P and a heatexchanger through which hot water from the base of the column E passes, into the upper part of the column E, or by supplying gaseous ammonia, for example, that obtained from a plant for its synthetic production, through a pipe H, in which case, the pressure of the gas acts through a bell I and cock L to regulate the supply of acid. A steam coil M in the base of the column E serves to warm the column at the commencement of the operation.
