Title: Chelated metalloxane-siloxane polymers
Inventor: SUTTON ROBERT ARTHUR
IPC: C08G77/58
Filed: 1964-01-02
Abstract: Chelated metalloxane-siloxane polymers comprising units of the formula <FORM:1029040/C3/1> wherein each X represents a chelate group, n represents the valency of M less 2, Y and Y1 are each H or an alkyl group, and M is Al, Ti or Zn, may be made by hydrolytically condensing a dialkoxy aluminium, titanium or zirconium chelate and a tetra alkyl silicate.  Chelating compounds specified are 8-hydroxyquinoline, organophosphinic acids, acetylacetone and aromatic Schiff's bases.  The metal chelate and silicate are preferably present initially in equimolar proportions.  The process is preferably effected in a solvent medium at elevated temperatures using a stream of wet nitrogen and/or small volumes of water of about 5% by weight of the reactants.  In an alternative process the metal chelate and silicate are condensed in the presence of an organic acid anhydride, e.g. acetic anydride.  In a further process, a tetraalkyl-titanate or -zirconate is condensed with a tetraalkyl silicate and the condensate is then chelated.  In a typical Example (1), a stream of wet nitrogen was passed through a toluene solution of di-n-butoxy-titanium bis-(quinolate) and tetraethyl silicate heated at reflux temperature for 36 hrs.; 1 ml. of water was added, the heating continued for 8 hrs. and the water was then removed azeotropically, this addition and removal of water being repeated twice.  An orange-coloured polymer precipitated during the hydrolysis and was subsequently removed and dried.  Uses.-The polymers can be dissolved or dispersed in organic solvents to form surface-coating compositions.

Title: Improvements in or relating to rear-wheel driving mechanisms for motor cycles
IPC: B62M7/12
Filed: 1946-01-04
Abstract: 605,753. Universal joints. BIRMINGHAM SMALL ARMS CO., Ltd., and POPPE, E. Jan. 4, 1946, No. 319. [Class 80 (ii)] [Also in Group XXXI] In a rear wheel driving mechanism for motor cycles of the type comprising a shaft drive and worm and worm-wheel, the worm and wormwheel are mounted for limited floating movement relative to the wheel hub so that movement between the worm and the worm-wheel arising from deflection of the wheel during riding of the motor cycle and thrusts of the worm-wheel on the worm in a direction radial to the worm-wheel are both substantially reduced. As shown, a gear casing 10 houses a worm 12 mounted in antifriction bearings whose forward end is adapted to be coupled to and driven from the gear-box by a drive shaft 14. The worm meshes with the teeth 15 of a worm 16 in the form of an annulus, the annulus being mounted relative to the casing 10 on bearings 17. The wheel spindle 18 extends centrally through the worm-wheel, the adjacent end of which is threaded at 19 to receive a cover-plate 21, which has a sleeve 20 formed therewith which serves to support one of the bearings 17. The other end of the spindle carries the hub 22 of the rear wheel, which provides a pair of flanges for supporting the spokes. One of the flanges has a brake drum 23 secured thereto. An extension 25 of the hub 22 is provided with involute teeth 26 which engage corresponding teeth 27 formed on one end of a member 28. The other end of the member is flanged outwardly at 29 and then axially at 30 and the portion 30 is formed with teeth 31 meshing with a corresponding set 32 provided internally in the worm annulus 16. Limited clearance is provided between all the intermeshing teeth, between the flange 30 and bearings 17 so that some deflection of the spindle 18 is allowable and the worm and wormwheel and the casing 10 have floating movement relative to the hub 22. When it is necessary to remove the hub, this is done by merely disengaging the teeth 26, 27 and sliding it relatively to the spindle 18.

Rotation of the sub-frames 102 is rendered possible by engaging the fork tines 62 with the ground and thereby raising the front of the vehicle. When the sub-frames 102 are in their retracted positions shown in Fig. 7 the fork tines 62 can then be inserted into respective sockets (140) located on a truck (146) so that on application of downward pressure to the tines 62 the vehicle is raised relative to the tines 62 and their respective sockets (140) to assume the position of Fig. 8 (not shown) so that the vehicle can then be transported by the truck (146). The fork member 60 is mounted on a frame 44, 46 which is guided for vertical movement by the guide 20, vertical movement of the frame 44, 46 being effected by an hydraulic ram (36, 38), Fig. 2 (not shown). The fork guide 20 is tiltable about 22 by means of an hydraulic ram 66, 68.
