Title: Improvements connected with dynamometers
IPC: G01L3/18
Filed: 1951-07-12
Abstract: 713,538. Rotary-absorption dynamometers. GARRETT, F. A. July 9, 1952 [July 12, 1951], No. 16593/51. Class 106 (2) A hydraulically controlled dynamometer comprises two upright brake levers 14 coupled at their upper ends by fluid pressure operated loading cylinders 25 and at their lower ends by brake shoes 9, the levers 14 being mounted on intermediate pivots 16. The brake drum 5 is mounted in bearings 4 on a fixed base 2, and the brake shoes 9 are pivotally connected together at their lower ends by a pin 10 fitted with rollers 11 bearing on the arcuate upper surfaces 12 of hardened steel plates 13 fixed to the base 2. In operation, with the drum 5 rotating, a pump 34 is operated to apply fluid pressure to the cylinders 25 so that the levers 14 are thrust apart at their upper ends to bring the brake shoes 9-9 into engagement with the drum 5, thus applying a frictional load to the dynamometer. According to the direction of rotation of the drum 5 one or other of the levers 14 will be caused to press at its upper end 30 against one of two reaction cylinders 29, the resulting pressure in the reaction cylinder 29 being transmitted by a pipe 75 to a cylinder and a ram operating a pendant lever 72 of a steelyard arm 68. A loading weight 175 is then shifted along the steelyard arm 68 until the arm is horizontal The reaction cylinders 29 are arranged such that they are tangential to the arcuate path of movement of the levers 14. The free end of the arm 68 moves between electric contacts 79, 80 to control the motor circuit of an electric motor 77 moving the weight 175. The motor 77 is coupled to a counter the reading of which, when a balance has been obtained, is a measure of the torque exerted by the drum 5. Alternatively, the movement of the arm 68 between the contacts 79, 80 is adapted to control the motor circuit of an electric motor 37 driving means for feeding the loader cylinders 25. The fulcrum pins 16 are connected together by arms 17 but are provided with quick release means to release the load on the brake drum 5. Specifications 563,534 and 693,171 are referred to.

Title: Protection of rubber articles
Inventor: NEALE ALBERT EDWARD TONEY
IPC: C08J3/22
Filed: 1957-05-28
Abstract: In vulcanized rubber articles are dispersed an antiozonant and, as a carrier therefor, a liquid substance which increases the concentration of the antiozonant at the surface of the article. Suitable as the carriers are liquid soaps of polyvalent metals and long chain fatty acids, liquid organic polysulphides, liquid polyoxyethylene condensation products, liquid hydrocarbon-substituted amino alcohols and liquid unsaturated carboxylic acid esters of polyhydric alcohols.  The amount of carrier may be 0,1-5% of the rubber.  Preferably a concentration of antiozonant of at least 20 micrograms/sq. cm. is produced on the rubber surface.  Examples are concerned with the incorporation into a vulcanizable natural rubber sidewall mix of the antiozonants N N1-dioctyl, N N1-dicyclohexyl, N-phenyl N1-cyclohexyl and N-phenyl N1-isopropyl paraphenylene diamines and di-n-butyl, di-hexadecyl, diethyl benzyl, dioctadecenyl, di-hexyl, di-n-dodecyl and tributyl thioureas and, as the liquid carriers, of polyoxyethylene amine, a low m.w. ethylene polysulphide, an oleyl amino polyethylene oxide product, nickel and strontium laurates, phenyl diethanolamine, the reaction product of sodium disulphide and dichlorohydrin, oleyl amino trimethylol methane, lauryl aminoethanol and sorbitan monooleate, and with the incorporation into a vulcanizable mix containing a copolymer of butadiene and methyl isopropenyl ketone in 60:40 proportion and into a vulcanizable mix containing a copolymer of butadiene and styrene in 75:25 proportion of the antiozonants N-phenyl N1-isopropyl phenylene diamine and di-n-butyl thiourea and, as the liquid carrier, of an oleyl amino polyethylene oxide product.  Compositions of the antiozonant and liquid carrier for incorporation into vulcanizable rubber mixes may be rendered powdery by the addition of an inert substance such as kieselguhr.

Patent GB-689915-A (GB)
Title: Apparatus for filling products in containers
IPC: B65B31/02
Filed: 1950-07-10
Abstract: 689,915. Filling containers. SCHWARZ ENGINEERING CO., Inc. July 10, 1950 [July 11, 1949], No. 17229/50. Class 125(ii) [Also in Group XXX] In apparatus for filling flanged-mouthed containers the containers 44 closely juxtaposed with their flanges 44<SP>1</SP> in overlapping relationship are continuously conveyed with an uninterrupted motion past a stationary filler nozzle 129 supplying a continuous stream of the product to be filled. The nozzle may be elongated to span a number of the containers 44 which are carried by an endless conveyer chain 59 supported on rails 60. The filler comprises an elongated reservoir 118 with a flange 119 at its lower end removably fixed by clamps 124 to a base plate 123 with an elongated nozzle 129. A groove 121 in the flange 119 is supplied with superheated steam through pipes 122 to form a sterile seal. The nozzle 129 has a longitudinal passage 131 in which is slidably mounted a rod 132 with a handle 166 for regulating the flow. A cylindrical baffle 138 prevents direct flow of the product from the feed pipe 33 to the nozzle 129 to ensure that the product flows in a uniform sheet along the entire length of the nozzle. A star wheel feeding the containers on to the conveyer 59 has pockets so spaced that the containers have their flanges overlapping to minimise spillage. The speed of a pump supplying the sterilised product to the filler, and the speed of the conveyer are adjusted so that the containers are filled as they pass the nozzle, variations in the viscosity of the products being provided for by adjusting the cross sectional area of the nozzle by the rod 132, which also varies the velocity of flow. Any spillage collects in a sump 114 from which it may be returned to the product supply tank. For adjusting the filler head to different heights of containers, side walls 151 slide in recesses 152 and are fixed by bolts 156 accessible by lifting the cover 159 about a hinge 161. The containers move between guide rails 62 vertically and laterally adjustable for different sizes of containers. After filling, the containers pass to a conveyer 66, Fig. 5b, moving faster than the conveyer 59, and are spaced apart by a rotating worm 72 before being fed into a sealing or closing machine. Perforated pipes 111 supply superheated steam which fills the apparatus and prevents access of air, the temperature being maintained by insulated walls 41. The containers are washed, dried, preheated and sterilised before being fed to the filler, and the product is heated for sterilisation and cooled before feeding to the pipe 33. Hot sterilising water can be supplied to the pipe 33 'and filler head before starting.

The coating 3 may include softeners, non-drying oil, casein, dextrin, synthetic or natural resin, carbolic acid, watercolours, and lithographic colours. It may have a pattern on it or may be formed as a pattern, e.g. it may be covered with or formed as a fine lattice.

The springs 26 may, as shown, be leaf-springs between a recess 25 in the tooth ring 18 and a lug 6 on the armature 16 or, may (Fig. 5, not shown) be radially disposed spring pins between the armature and toothed ring. Pins 27 fast with the armature 16 engage axial slots in the toothed ring 18 to provide limited relative axial movement.
