Abstract: 750,405. Locks. NEIMAN, A. Oct. 21, 1952 [Oct. 27, 1951], No. 26407/52. Class 44. [Also in Group XXXI] A safety lock for vehicle steering gear comprises a housing secured to the steering column, a lock rotatable within the housing by means of a key and carrying a bolt engageable within an opening in the steering pillar upon inward movement of the lock, the latter also carrying a transverse stud engageable by rotational movement of the lock within a recess in the lock housing into which it is then urged by spring means thereby to secure the lock in its operative position against the action of a return spring tending to move the lock outwardly of the housing into an inoperative position, and means to secure the lock against outward movement beyond the inoperative position. In the arrangement according to Fig. 1, in which an insertion lock 3 of known type having a bolt 5 is slidably mounted in a housing 1 secured to a vehicle steering head tube 2 and in which the bolt 5 is adapted to engage a steering column 4, against a return spring 9, a stud 7 is received in a recess 8 or 13 on the housing to lock the lock in the housing, the outward movement being limited by a projection 15 which engages a pin 16 in the housing. In a modification, Fig. 3, a cap 17 pivoted about a fixing screw 18 forms a stop for the look when the cap is swung to the open position. A ball catch, Fig. 5 (not shown), in the housing prevents inward movement of the lock until the key has been inserted and turned. In a modification, the ball catch may be replaced by a crescent-shape spring having claw-like ends. In another modification, Fig. 6 (not shown), an additional spring is located between the lock and its housing. According to Fig. 3, the bolt which is not rotatable with respect to the housing, is coupled to a rotary part of the lock by a spring 35 which effects the engagement of the stud 7 with the recess 8 or 13 in the housing.

Abstract: A vinyl ether of the formula ROCHR1CH2OCH=CH2 wherein R is a C1-C8 alkyl group and R1 is hydrogen or an alkyl, aralkyl or aryl group is obtained by simultaneously reacting, in solution, and in the presence of an alkaline compound of an alkali metal as catalyst (1) acetylene, (2) an alkylene oxide of the formula <FORM:0989883/C2/1> and (3) an alcohol ROH; also a vinyl sulphide of the formula HOCHR1CH2SCH=CH2 wherein R1 is as defined above is obtained by simultaneously reacting in solution in a solvent (1) acetylene, (2) an alkylene oxide of the above formula and (3) sodium or potassium hydrosulphide. In the reaction to form the vinyl ether another vinyl ether of the formula R(OCHR1CH2)nOCH=CH2 wherein n is an integer greater than 1, e.g. 2 or 3, is usually obtained as by-product.  In one form of the process for forming the vinyl ether the alkylene oxide, preferably ethylene oxide, and preferably in solution in the alcohol, is introduced into the alcohol containing the catalyst and which is maintained above room temperature under acetylene pressure, and in another method the alcohol (together with the catalyst) and the alkylene oxide which is preferably in solution are introduced separately into a liquid medium composed of the alcohol reactant maintained at above room temperature and under acetylene pressure.  Specified alkylene oxides are ethylene-, propylene- and styrene oxides and specified alcohols are methanol and tertiary butanol. Examples are given for the production of (a) 2-(t.-butoxy)ethyl vinyl ether and 2-(t.-butoxy-ethoxy)ethyl vinyl ether and (b) 2-methoxy-ethyl vinyl ether and 2-methoxyethoxyethyl vinyl ether, the alkaline catalyst being potassium t.-butoxide and potassium methoxide respectively.  In preparing the vinyl sulphides a solution of the alkylene oxide may be introduced by a pump into a solution of the hydro sulphide maintained above room temperature and under acetylene pressure or the alkylene oxide and the hydrosulphide may be introduced separately and in solution into a liquid medium maintained above room temperature and under acetylene pressure. Water is the preferred solvent in the vinyl sulphide process but other solvents, e.g. an alcohol such as methanol, or dioxane, may also be used.  The molar ratio of hydrosulphide to alkylene oxide is preferably about 2:1.  The acetylene pressure in the production of the vinyl ether and vinyl sulphide is preferably above 350 p.s.i. and each process can be carried out continuously.  Examples are given for the production of (a) 2-hydroxyethyl vinyl sulphide together with a small amount of 2-vinyloxyethyl vinyl sulphide and (b) 2-hydroxypropyl vinyl sulphide, the hydrosulphide used in each case being sodium hydrosulphide.
