Title: Improvements in or relating to hydrogenated liquid polymer oils
IPC: C10M143/12
Filed: 1955-05-04
Abstract: Oily polymers of butadiene-1,3 or higher homologues thereof, e.g. piperylene, isoprene and dimethylbutadiene or copolymers with styrene or its ring alkylated homologues, e.g. p- or m-methyl styrene, dimethyl styrene or the corresponding ethyl substituted homologues, prepared at 25 DEG  to 105 DEG  C. with a sodium catalyst and an inert hydrocarbon diluent and an ether promotor are hydrogenated to yield products of reduced iodine number and colour.  The hydrogenation may be carried out by gradually adding gaseous hydrogen under pressure and elevated temperature in the presence of a catalyst such as nickel, platinum and metal sulphides.  The hydrogenated copolymers may be further sulphurized and/or phosphorized, and sulphonated and phosphorized preferably in the presence of an inert solvent and/or diluent and the products are then neutralized.  The after treatments may be carried out in the presence of a fatty oil, or a mineral lubricating oil.  The hydrogenated copolymer may also be reacted with dihalogenated or polyhalogenated hydrocarbons, and halogenated paraffin wax, preferably in the presence of a Friedel Crafts catalyst; acylated with acyl halides derived from fatty acids, or short chain acyl halides; or sulphonated.  The products may be used as varnish extenders, in floor tiles, printing inks, paints, as binding agents for plywood, as plasticizers for natural or synthetic rubbers, asphalt, polyethylene and wax, and as an addition agent for mineral or synthetic lubricating oil.

Title: Improved windscreen wiper drive mechanism
IPC: B60S1/20
Filed: 1952-05-27
Abstract: 716,457. Windscreen cleaners. GENERAL MOTORS CORPORATION. May 27, 1952, [June 29, 1951], No. 13359/52. Class 138 (1) A windscreen wiper drive mechanism comprises a primary drive shaft carrying a fixed pulley and two pulleys resiliently connected to the shaft and adapted to be locked at will to the fixed pulley, each of the said two pulleys having cable connected thereto, the free ends of the cables beiiig connected to the fixed pulley and each cable being adapted to drive a separate wiper, so arranged that either or both of'said two pulleys can be rotated against spring pressure when not locked, to slacken the respective cable. The shaft 28, Fig. 2, of an oscillatory type motor 25 drives through a blook 32 and U-shaped member 33, a shaft 31. Mounted on the end of the shaft 31 are three pulleys 40, 47 and 56; the pulley 40 being splined to the shaft and the pulleys 47, 56 being lockable with the pulley 40 to rotate therewith by means of a sleeve 65 and nut 66 threaded on the shaft. The abutting faces of the pulleys are provided with serrated sections to facilitate locking therebetween. Two grooves are provided in the pulley 40 and one groove is provided in each of the pulleys 47, 56. The ends 36a, 36b of a cable driving a pulley on one wiper actuating shaft are anchored to the pulleys 47 and 40 respectively while the ends 38a, 38b of another cable, driving a pulley on the other wiper actuating shaft, are anchored to the pulleys 40 and 56 respectively. The cables pass over idler pulleys positioned between the driving and the driven shafts. A spiral spring 52, Fig. 3, housed in a recess 50 in the pulley 47 is anchored at one end to the hub 45 of the pulley 40 and at its other end to a lug 53 formed in the pulley 47. Similarly a spiral spring 61, housed in a recess 60 in the pulley 56' is anchored at one end to the hub 45 and at its other end to a lug 62 formed on the pulley 56. Initially the pulleys 47, 56 are rotated to wind the springs 52, 61 and at the same time to slacken the cables, whereupon the nut 66 is tightened to lock the pulleys 40, 47 and 56 together. After the mechanism has been installed in the vehicle the nut 66 is loosened to allow the springs 52, 61 to partially unwind and to tighten the cables, whereafter the nut 66 is again tightened. In another embodiment the driving shaft of the motor carries the three pulleys, one being splined thereto and the other two being mounted on opposite sides of the fixed pulley. Nuts threaded on the shaft at the outer ends of the pulley assembly facilitate locking therebetween. In this case two helical torsion springs are enclosed in recesses formed between the fixed and outer pulleys, one end of each spring being secured to the fixed pulley and the other ends being secured, respectively, to each outer pulley.

Title: New heterocyclic boron compounds and a process for the production of boron hydrocarbons
IPC: C07F5/02
Filed: 1958-04-28
Abstract: Boron hydrocarbon polymers are produced by heating a borazane of the general formula H3 B.NR13 in which R1 is any desired hydro carbon radical to a temperature higher than 100 DEG C. with a polyolefine and in the absence of oxygen and moisture.  The products are oily liquids which cannot be distilled or can only be distilled with difficulty.  In examples, cyclododecatriene - (1, 5, 9) is heated with N - triethyl borazane and after distilling off a monomer of formula C12 H21 B a residue is left which solidifies in vitreous form after cooling; butadiene is heated with N-triethyl and after distilling off a product of empirical formula B2 (C4 H8)3 there is left as residue a viscous liquid of higher molecular weight.ALSO:Boron hydrocarbons are prepared by heating a borazane of the general formula H3B.NR13 in which R1 is any desired hydrocarbon radical to a temperature higher than 100 DEG C. with an olefine having one or more double bonds and in the absence of oxygen and moisture.  The amine and boron hydrocarbon may be separated by distillation.  The process may be carried out under pressure with low boiling or gaseous olefines but this is not essential.  Solvents or diluents such as hydrocarbons, ethers or tamines may be used.  With mono-olefines, boron trialkyls are formed.  With polyolefines the products may be polymers or monomeric addition compounds depending on conditions.  Thus cyclododecatriene -1,5,9 reacts with an N-trialkyl borazane, such as N-triethylborazane to form a heterocyclic compound of the empirical formula C12H21B and butadiene forms a heterocyclic compound of the formula B2 (C4H8)3.  Both of these compounds are novel. Other products described in examples are tridecylboron, triethylboron, tricyclohexyl boron, tri-(bicyclo-(2,2,1)-heptyl-2-) boron, and tri(2-phenylpropyl) boron.
