Title: Process of reclaiming waste rubber
IPC: C08J11/06
Filed: 1920-12-31
Abstract: Waste rubber previously freed from fibrous matter is highly dispersed in water or an organic liquid such as benzene, benzine, oil, petroleum, or chlorinated hydrocarbon, by treatment in a colloid mill such as that described in Specification 155,836.  The process is carried out between 15 DEG  and 120 DEG  C.  The dispersion is preferably accelerated by the addition of one or more of the following substances:-soaps of fats, resins, or naphthenic acid, or their raw materials; colloids such as glue, starch, dextrin, albumen, casein, protein, gelatine, resin emulsions, colophony, rubber latex, or disulphonaphthenic acids or their alkaline salts; rubber solvents such as benzene, toluene, xylene, mesitylene, pseudocumene, dichlorhydrin, aniline, toluidine, xylidene, phenol, cresol, tar oils, resin oils, or vegetable oils.  Alkalis, alkaline sulphides, ammonia, ammonium sulphide, or amines may be added to dissolve the sulphur.  The product is a latex-like dispersion, in which the free sulphur is present in true or colloidal solution and may be removed by treatment with organic sulphur solvents.  By prolonging the process of dispersion combined sulphur is also removed.  The rubber is recovered from the dispersion by ultra-filtration or by coagulation with organic acids such as acetic, tartaric, citric, glycollic, or amidoacetic acid.  The waste rubber may be worked on rollers with swelling agents before being subjected to the dispersion process.

Filed: 1961-10-12
Abstract: 987,680. Endless conveyers; packaging machines. AMERICAN MACHINE & FOUNDRY CO. Jan. 4, 1963 [Oct. 12, 1961], No. 36728/61. Headings B8A, B8C and B8S. A tray handling means for a cigarette handling apparatus comprises a magazine formed by walls 6, 8 which guide the trays stacked therein, two dog carrying endless chain conveyers 4 arranged to accept each first tray in succession from the magazine and to move it to a cigarette receiving position and further move it to a disposition on rails 40. The trays which are substantially U-shaped have their attitude controlled by a rail 14 engaging the trays at 16, 36 and a back frame of the apparatus engaging the trays at 10, 34. The trays are fed under gravity from the magazine when an arm 12 is pivoted about a point 18 by means of an arm 20 actuated by a cam 22 mounted on the shaft 23 of one of the conveyers 4. Further rotation of the cam 22 returns the arm 12 to its original position having allowed the lowermost tray 32 to be carried downwards on a pair of dogs 2. Once clear of the rail 14, this tray swings into a vertical position on the dogs 2 and is conveyed to the cigarette receiving point. The movement of the conveyers 4 is controlled by means responsive to the height of cigarettes in the tray. Upon filling, the tray is lowered on to the rails 40 where it is discharged from the line of the conveyers by means of pushers 30 operated by an arm 28 incorporating a roller 26 which engages a second cam 24 on the shaft 23. A pair of spring catches 42 are provided to hold the descending tray vertical. A further pair of spring catches 44 are provided alongside the rails 40 to prevent discharged trays from travelling back into the line of the conveyers 4. Each dog 2 may be pivoted on a centrally situated stud, Fig. 9 (not shown) and provided with a slot which abuts a tongue provided at the face of the stud. Specification 975,017 is referred to.
Patent GB-781885-A (GB)
Title: Improvements in or relating to windshield wiper assemblies and method of wiping a curved windshield
IPC: B60S1/36
Filed: 1954-12-20
Abstract: 781,885. Windscreen cleaners. PRODUCTIVE INVENTIONS, Inc. Dec. 20,1954 [May 7, 1954], No. 36731/54. Class 138(1). A method of wiping a rearwardly curved wing portion of a windshield by a wiper blade carried by a wiper arm, consists in oscillating the wiper arm across the windshield, reciprocating the wiper blade with respect to the wiper arm during the oscillation and rotating the wiper blade with respect to the wiper arm to cause the wiper blade to conform to the curvature of the windshield at all times. Referring to Figs. 1 and 2, the wiper arm comprises an inner section 1, adjustably secured by a nut 4 to a drive shaft 5 disposed in a mounting 6, an intermediate section 2 pivoted under the urge of a spring 7 to the inner section 1, a tubular guide member 8 secured in either of two positions to the section 2 by a rivet 9, and an extensible section 3 slidable and rotatable in the guide 8, which section 3 carries the wiper blade connector. A pin 13 Fig. 4, secured to the section 3, engages in a slot in the guide 8, the slot having a longitudinal portion 10 and a helical portion 11. The head 14 of the pin 13 is universally pivoted to one end of a secondary arm 15 formed of two members 16 riveted together as at 20. The other end of the arm 15 is universally pivoted to the head 17 of the shaft of a bolt assembly 18, Fig. 3, which is adjustably secured in a slot 27, Fig. 2, in a fitting 19 adjustably secured to the mounting 6 by nuts 25, 26, Fig. 1. The underside of the fitting 19 is serrated to engage serrations on the top of the nut 26. Referring to Fig. 9, as the wiper arm moves from the parked position shown in full lines, to the position 32, the pin 13 is caused to move along the slot 10 to thus slide the section 3 and wiper blade longitudinally of the guide 8 but without rotation relative thereto. As the wiper moves from position 32 to the position shown on the extreme right of Fig. 9, i.e. on the rearwardly extending wing 31 of the windshield, the pin 13 enters the slot portion 11 and the section 3 and wiper blade are thus rotated relative to the longitudinal axis of the guide 8, and the blade is retained in contact with and normal to the wing 31. Without the present construction the blade would follow the path 33 and on reaching the wing portion a part of the blade would be out of contact with the windshield and also the windshield frame would be fouled. In a modification described with reference to Fig. 2a (not shown) the slot in the guide is formed with two longitudinal portions with an intervening helical section. The adjustment of the fitting 19 relative to the mounting 6, the adjustment of the bolt assembly 18 on the fitting 19, and the adjustment of the guide 8 on the arm section 2, allow of the wiper assembly being used on different windshields.

[Class 97 (iii).] For measuring the thermal radiation from a heating apparatus, such as a gas or electric fire, a radiometer capable of integrating the quantities of heat intercepted by it is combined with means for producing a uniform angular movement between the radiometer and the radiating body. In the form shown the radiometer comprises a synthetic resin or wooden frame b, c, supporting by means of light strips d two sets of massive metal, e.g. copper, blocks a. The latter are of semi-circular cross section and may be ribbed on their outer faces. Packing pieces e separate the blocks a from one another and thermocouples f of iron and constantan, arranged in series, interconnect the two sets of blocks a and are connected by conductors q to an indicating instrument. The radiometer is mounted for angular adjustment in a bracket h, which may be clamped by the cam i on a semi-circular carrier g pivoted about a vertical axis through the radiating body mounted on the platform l and screened at the sides by metal rings n. In use the carrier g is uniformly rotated by hand, electric motor, spring, or weight, so that the radiometer sweeps out a zone, the radiant heat intercepted being conserved by the masses a. By adjusting the position of the radiometer on the carrier g and repeating the latter movement, any desired part of the hemispherical surface swept out by the carrier g may be covered.

Abstract: 1,235,792. Electric selective signalling: tape readers. SIEMENS A.G. 24 July, 1969 [25 July, 1968], No. 37256/69. Headings G4H and G4M. [Also in Division H4] A parallel-bit signal in which all the leading edges and/or all the trailing edges may not be simultaneous, e.g. owing to non-simultaneous closure of tape reader contacts or to transmission delays, is sampled by subjecting the distorted signal to a delay less than the duration of one bit, and sampling the delayed signal with a pulse occurring at the instant at which the first trailing edge occurs in the undelayed signal. In the embodiment described each 6-bit parallel-bit signal from a keyboard is transmitted as two simultaneous frequencies, each chosen from a respective group of four f1-f4, f5-f8, Fig. 2 (not shown), followed by two frequencies f1, f5 representing zero level. At the receiver 6 filters develop the 6-bit signal. The bits are now delayed, e.g. by monostable units, and sampled as described above.

Title: Improvements relating to sheet-like mouldable compositions
IPC: B29C43/00
Filed: 1963-09-26
Abstract: A sheet-like mouldable composition comprises a mat of fibres within the interstices of which is dispersed from 2% to 70% by weight of total solids of a thermoplastic or thermosetting resin in the form of unfused particles between 0.01 and 0.55 microns in size.  The fibres used are preferably hollow cellular jute fibres but may be of cellulose, glass, nylon, rayon, coconut, brass, aluminium or steel. When the fibres are of jute, some of the binder particles penetrate into the hollow cells of the fibres. The binder is preferably polyvinyl chloride, but the specification includes a list of other suitable binders.  The fibrous material is preferably needled or otherwise mechanically treated in the first place to form a compacted web which is then immersed in an impregnating bath containing a dispersion of the resin material. The impregnated web is dried by means of hot air.  The fibres may be reinforced with a woven or matted layer of burlap, cotton cloth or netting.  A moulded product may be made by forming the sheet-like composition under heat and pressure.  The mat may be folded upon itself where bends or corners are to be formed, so that the mat is compacted to a greater extent in these places than elsewhere.
