Abstract: 606,356. Thrashing-machines. CASS, J. A., and KAHN, W. Nov. 29, 1945, No. 32235. Convention date, July 16. [Class 58] In an apparatus for thrashing shell-enclosed or podded crops such as beans and peas, converging conveyer belts 3, 4 form the opposite sides of the bottom of a feed hopper (not shown) and pass over terminal rollers 5, 7. A rubbing drum 25 provided in its surface with short studs 27 is mounted close to the rollers 5, 7 so that the pods or shells held between them come in contact with the drum as it rotates.

Abstract: 1,136,518. Reciprocating conveyers. SIMPLEX CORP. 17 July, 1967 [8 Sept., 1966], No. 32743/67. Heading B8A. A feed system comprises a longitudinally arranged series of work supporting stations including a starting station at which workpieces are deposited serially, a delivery station from which workpieces are removed serially and transfer mechanism for advancing all of the workpieces one station whenever the workpiece at the delivery station is removed, the transfer mechanism also being operable to advance all the workpieces in rear of an intermediate empty station by one station so as to maintain all the stations in filled condition. Stations for workpieces W are provided by pairs of notches 10 in frame members 12, the workpieces being advanced by dogs 24 pivotally mounted on a transfer slide 14. A sensing lever 36 for controlling the operation of the dog 24 is pivotally carried adjacent each notch 10 by one of the frame members 12. A reciprocable control bar 44 is connected by links 50 to a series of control members 48, the latter being movable generally upwardly and counterclockwise. Assuming workpieces Wa, Wc are provided at stations 10a, 10c respectively but no workpiece is provided at station 10b; it is required that dog 24a be pivoted to be engageable with workpiece Wa and this is effected by movement to the right of the control bar 44, as indicated in Fig. 6 (not shown). This bar then returns to the left and the transfer slide 14 is moved to the right to advance the workpiece Wa. When all the stations are filled with workpieces it is arranged that all the dogs are moved downwardly and will remain so. When the workpiece at the delivery station is removed and if all the remaining stations are filled, all the dogs are knocked down upon reverse movement of the slide 14 and are then raised so that every workpiece is advanced one station. As long as each station remains filled, the control bar 44 and the transfer slide 14 reciprocate idly. To avoid this, switches 60 provided at each station may be connected such that reciprocation is terminated until one of the workpieces is removed.

Filed: 1955-11-18
Abstract: Ar-vinyltoluene polymer particles of diameter up to 10m  or aggregates of such particles of diameter up to 15m  are sulphonated in the presence of liquid sulphur dioxide by agitating at - 20 DEG to +40 DEG  C. with at least 0.7 mols. per mol. of monomer of a sulphonating agent comprising at least 10 mol. per cent of chlorosulphonic acid, a solution of said polymer in 9 times its weight of toluene having a viscosity at 25 DEG  C. not greater than a maximum in the range 10-40 centipoises, the maximum being inversely proportional to the proportion of chlorosulphonic acid in the sulphonating agent.  The sulphonating agent may include sulphur trioxide or complexes of sulphur trioxide with dioxane or bis (b -chloroethyl) ether.  The polymer should be free of cross-linkages, soluble in toluene, dioxane or methyl ethyl ketone, and may contain up to 40 per cent of one or more of vinyl esters, vinyl ketones, vinyl ethers, ethylene, isobutylene, styrene, a -methyl styrene, methyl methacrylate, ethyl acrylate, acrylonitrile, methacrylonitrile, maleic anhydride, vinyl halides or vinylidene halides.  The polymer may be finely-divided by grinding or crushing, by atomizing the dissolved or molten polymer or by coagulating, e.g. by freezing or adding electrolytes, or spray-drying a polymer emulsion or dispersion.  The polymer may be sprinkled on, suspended in air or nitrogen and blown into, or added in solution in sulphur dioxide to a sulphur dioxide solution of the sulphonating agent. Alternatively the polymer and sulphonating agent solution may be introduced simultaneously into sulphur dioxide and the process made continuous by withdrawal of the reaction mixture.  The product may be separated by filtering or centrifuging, and converted to salts by reaction with ammonia, sodium or potassium hydroxides or amines.  The salts may be used in treating textiles, forming emulsions and dispersions and for soil conditioning.
