Title: Improved process for the emulsion polymerisation of conjugated dienes
IPC: C08F36/04
Filed: 1967-10-25
Abstract: 1,202,597. Aqueous emulsion polymerization of conjugated dienes. SOC. NATIONALE DES PETROLES D'AQUITAINE. 25 Oct., 1967 [26 Oct., 1966; 9 Oct., 19671, No. 48536/67. Heading C3P. One or more conjugated dienes are polymerized in aqueous emulsion in the presence of a free radical catalyst system and of at least one chain modifier, wherein the addition of the modifier to the emulsion is regulated so that, at least after an initial minor part of the polymerization, the maximum value (R) and the minimum value (r) of the ratio of the weight of modifier present to the weight of remaining monomer are such that the quotient R: r is in the range 1 to 4. The process may be effected continuously with continuous or batchwise addition of the modifier, suitably in decreasing amounts as the polymerization proceeds. The product may be vulcanized. In examples, butadiene or isoprene are homopolymerized in the presence of potassium resinate, ferrous sulphate, paramethane hydroxy peroxide and perdodecyl - mercaptan, and in some cases a sulphoxylate solution, sodium hydrosulphite, an antioxidant, and sodium polysulphide.

Title: Organotin esters and their use in stabilising chlorine containing polymers
IPC: C08K5/13
Filed: 1963-12-09
Abstract: Halogen-containing polymers, e.g. polymers of vinyl chloride or vinylidene chloride, or copolymers thereof with other ethylenically unsaturated monomers are stabilized with organotin compounds of formula R2Sn(OOC.CH=CHCOOR1)2 wherein R is an alkyl radical containing less than 10 carbon atoms and R1 is a substituted or unsubstituted cyclohexyl radical (see Division C2).  0.1 to 10 parts by weight of the organotin compound, which may be a single compound or a mixture of such compounds are blended with 100 parts of the halogen-containing polymer by Banbury blending, dry blending or milling. An example illustrates the improved resistance to degradation during outdoor weather of polyvinyl chloride stabilized with 3 parts per hundred of dibutyltin bis-(cyclohexyl maleate).ALSO:The invention comprises organotin compounds of formula R2Sn(OOCCH = CH.COOR1)2, wherein R is an alkyl radical containing less than 10 carbon atoms and R1 is a substituted or unsubstituted cyclohexyl radical.  They are prepared from maleic acid or maleic anhydride, the appropriate dialkyltin oxide and the appropriate cyclohexanol.  The cyclohexanol may be reacted with maleic anhydride in e.g. benzene, and the half acid ester formed, isolated if desired, further reacted with the dialkyltin oxide in benzene by removing water of reaction azeotropically.  Specific compounds are dibutyltin bis-(cyclohexyl maleate) and dibutyltin bis-(2-methylcyclohexyl maleate).  The compounds are used as stabilisers for halogen containing polymers (Division C3).

Title: Door latches for motor vehicles

Filed: 1972-10-27
Abstract: 1353439 Locks AISIN SEIKI KK 27 Oct 1972 [27 Oct 1971] 49611/72 Heading E2A A door latch for a motor vehicle comprises a bolt retainable in operative position by a pivoted detent 26 and releasable by a lever member 12, a keyless locking member, a lever 30, pivoted on a member 20 pivoted to the releasing member 12 which lever moves the releasing member to an inoperative position when the bolt moves to latching position with the member 12 retained in latch releasing  position. The bolt is connected to a disc 47 by a shaft 49 pivotally mounted on a base plate 10. The disc has teeth 45, 46 for safety or fully latching by a tooth 44 of the detent. When the member 12 is actuated either by an outside door handle or an inside door handle connected to the member by a lever 18 the member 20 is moved downwardly so that a surface 25 thereon engages a projection 27 on the detent to release the detent from the disc and releases the bolt from a keeper urged by a spring 50. When the door is closed with the releasing member actuated from outside the disc 47 rotates anti clockwise with the bolt and a flange 52 of the disc contacts one projecting arm of the lever 30 which is pivoted in a slot in the member 20 with the other arm abutting a surface of the member 20 whereby the member 20 is moved clockwise to its locking position. When the member 12 is released the member 20 remains in locking position with the surface 25 out of contact with the projection 27 of the bolt when the member 12 is actuated thereby effecting keyless locking, when the releasing member 12 is actuated with the locking member inoperative to release the bolt the flange 52 strikes the other side of the projecting arm of the lever 30 -and the lever pivots so that the member 20 remains operative. The member 20 is also movable to locking position by actuating a locking lever 23 by an inside push button or an outside lock, the lever 23 having a pin 24 engaging in a slot 22 in the member 20 for connection therewith. If the door is closed with the locking member operative the pivotal movement of the detent riding over the teeth of the disc causes a member 29 on the detent to contact a surface 28 of the member 20 to move the member from the locking position to the operative latch releasing position thus cancelling the locking action.

Barrels 3c &c. fed along an endless conveyer 1 past a series of stations strike a deflector arm 5 which is thereby actuated to transfer said barrel to a second endless conveyer 7 extending through a station at right angles to the conveyer 1. The barrel travels through the station until it abuts a stop 8 whereupon the deflector arm is returned to its position across the conveyer 1, a stop 9 is raised behind the barrel and the barrel is raised from the conveyer 7 to undergo, e.g. a washing operation. During the washing operation the stop 9 is lowered whereby on completion of said operation, the barrel is delivered to a further conveyer 4. The stop 9 is then raised and the stop 8 lowered to allow a barrel 3b, held in a storage position during the washing of the first barrel, to move forward to said washing position and so repeat the cycle. Whilst the second barrel was held in the storage position, i.e. the station has its full complement of barrels, the arm 5 is in its retracted position so that barrels on the conveyer 1 proceed to the next vacant station. Should all the station be full the barrels are returned by a conveyer (not shown) to the start of the conveyer 1. A control circuit (Fig. 2, not shown) is described.
