Title: Production of alkali lactam solutions for polymerisation purposes
Inventor: BAYERLEIN FRIEDRICH
IPC: C08G69/18
Filed: 1963-04-09
Abstract: Solid solutions of alkali metal lactams in lactams, wherein the lactam contains 4-12 carbon atoms, are made by heating an alkali metal alcoholate of an alcohol containing 1-3 carbon atoms with an amount of lactam to give the required concentration of the alkali metal lactam in lactam solution and evaporating the alcohol formed under reduced pressure by stirring the reaction mixture at temperatures below the polymerization temperature of the lactam. Suitable lactams are pyrrolidone, piperidone, oenantholactam, caprolactam, caprylolactam, laurolactam, b -methyl-e -amino-caprolactam and methylene-bis-caprolactam. The solid solutions are used as catalysts for the polymerization of lactams (see Division C3).ALSO:Solid solutions of an alkali metal lactam in the lactam, which are prepared by reacting an alkali metal alcoholate of an alcohol containing 1-3 carbon atoms with an amount of lactam necessary to achieve the desired concentration of alkali metal derivative in the lactam and evaporating off under reduced pressure the alcohol formed, are used as catalysts, either alone or with activators, for the polymerization of lactams.  The alkali metal lactam solution is preferably added in amounts of 0.1 to 1.0% by weight of alkali metal with reference to the total weight of polyamide forming material. Activators which may be used are, e.g. acid chlorides or isocyanates, substituted ureas or methanes.  Lactam derivatives which are used as catalysts are the potassium and sodium derivatives of lactams containing 4-12 carbon atoms in the ring, which may be substituted by alkyl or aryl groups, and lactams which are attached to a second lactam ring by an alkylene bridge, e.g. methylene-bis-caprolactam.

Title: Ram mechanism for propelling vehicles along a railway
IPC: B61J3/08
Filed: 1955-05-19
Abstract: 803,587. Vehicle propelling mechanism. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, P. T. May 18, 1956 [May 19, 1955], No. 14451/55. Class 104 (2). A reciprocating ram mechanism for propelling a vehicle along a railway comprises a biased pusher arm 1 pivoted at 2 on a trolleytype crosshead reciprocated along a track, the arm carrying a roller 4 on one or both sides which traverses a guide member 5 with front and rear pivoted flaps 6, 7 to retract and raise the pusher arm. In operation, as the retracted pusher arm is moved forwardly, the roller 4 first moves in contact with the lower surface of the flange 9 of a stop member 10 at the end of which the pusher arm pivots upwardly to operative position in contact with the vehicle as the roller runs along the upper surface of the flap 7 which may have a striker plate 14. The roller then passes above the upper surface of the flange 11 of the guide member 5 till it reaches the flap 6, which pivots downwardly, the flap pivoting upwardly again when the roller runs free at the end. When the movement of the pusher arm is reversed the roller 4 runs along the undersurface of the flange 12 of the flap 6 so lowering the pusher arm to inoperative position. The roller then moves along the undersurface of the flanges on the guide member 5 and flap 7 which pivots upwardly. The roller then contacts the undersurface of the flange 9 on the stop member 10; the pusher arm is thus returned to its initial position. The pusher arm may be biased downwardly and the front flap 6 and stop member 10 may be omitted. The pivot 2 may be forward of the rollers 4 in which case the flaps 6, 7 are pivoted downwardly and upwardly respectively.
