Title: Processes for the reaction of silanic hydrogen-bonded siloxanes with unsaturated organic compounds
IPC: C07F7/08
Filed: 1958-12-12
Abstract: A siloxane containing at least one Si-bonded hydrogen atom is reacted with an organic compound containing ethylenic or acetylenic unsaturation (including a silane with such unsaturation) by heating the reactants together in the presence of platinum as catalyst.  The platinum is preferably supported on finelydivided charcoal or deposited on gammaalumina, and the reaction is conducted, e.g. at 100 DEG  to 160 DEG C.  The unsaturated compounds may contain functional groups, e.g. hydroxyl, ether, aldehyde, acetal, amine, nitrile and epoxide.  The reaction product may be equilibrated with conventional siloxanes. Examples are given describing the preparation of the adducts by addition to <FORM:0914282/IV(a)/1> of (1 to 5) unsaturated hydrocarbons, (6 to 14) hydrocarbons containing vinyl unsaturation and an additional functional group, (15 to 35) compounds containing allyl unsaturation and an additional functional group, an unsaturated silane and an acetylenic compound containing a hydroxy group being used in (33) and (35) respectively, and (36) hexachlorobicycloheptenylpentenoate, 1,1-dihydroperfluorobutylpentenoate and 1,1,5-trihydroperfluoropentylpentenoate.  Uses: As mould releases, cosmetic ingredients, lubricants, antifoams, hydraulic fluids and as intermediates in the production of silicone elastomers and thermosetting resins.  Siloxacyclopentanes can be obtained by dehydration of certain of the above prepared adducts.  Thus in Example (31), the adduct of (19) was dehydrated by heating to 200 DEG -210 DEG C. (or lower with an alkaline catalyst) to yield the cyclic ester <FORM:0914282/IV(a)/2> (where Me=methyl) which can also be made from Me3SiO(SiMe.H.O)2SiMe3 and allyl alcohol by dehydration and rearrangement in the presence of KOH; (32) similar dehydration of the adduct of allyl alcohol and sym-tetramethyldisiloxane yielded <FORM:0914282/IV(a)/3>  Reference has been directed by the Comptroller to Specification 796,576.

Bobbins 13 of different shapes and sizes are adapted to be mounted upon a hollow rod 1 secured to a warp creel. The rod 1 has a slidable cone 2 thereon connected through a spring 10 and threads 9 with balls 8 in inclined grooves 7 of a headpiece 5 on the rod 1. On placing a bobbin in position the balls 8 are pushed into the grooves 7 and of the end of the bobbin engaged with the cone 2. On release of pressure on the bobbin the balls are caused to rise in grooves 7 so that they wedge between the interior of the bobbin 13 and the head 5. To release the bobbin the cone 2 is moved against the action of the spring by hand and further threads 16 pull down the balls 8 to release the bobbin.

Abstract: 1,056,035. Labelling machines. MORGAN FAIREST Ltd. Oct. 4, 1965 [Oct. 3. 1964]. No. 40370/64. Heading B8F. Bottle feeding mechanism in a machine for applying sealing labels over the wire limbs of wire stoppered bottles positions the bottles so that the labels correctly cover the wire limbs. Bottles B are advanced by a conveyer 16 and spaced by a worm 17 before entering a recess in an orientating wheel 19. Each recess has rollers to facilitate rotation of a bottle therein as the wheel 19 engages it with rails 23 and a belt 24. Rotation is stopped with the bottle correctly positioned for it to be fed to a further conveyer which takes it, held by a presser head, to a labelling station, when a recess 27 of a hook 26 pivoted at 28 engages the trailing wire limb of the stopper. Engagement of the hook, which is spring urged towards the recess, with the leading wire limb is prevented by an abutment on the hook camming it out of its path as the bottle rotates while the abutment is not effective to prevent engagement with the trailing wire limb.

As shown the frame 4 has two mutually perpendicular surfaces 4x, y to locate corresponding edges 9x, y of the display panel, the former pair of surfaces being pressed together by a spring 7 acting on the opposite edge of the panel. The panel and frame are attached to a substrate 1 by clamps 10 which can be removed after merely loosening screws 11 so that the display can easily be exchanged. The board 3 is a flexible printed circuit board and cylindrical resilient pads 6 are located beneath its edges to provide a resilient mounting for the display and to ensure good electrical contact between the display and circuit board. The latter feature can be checked visually after assembly and the circuit board terminals (3c), Figs. 13, 14 (not shown) are narrower than the terminals 9g to reduce the possibility of shorting. The substrate 1 carries a power cell 27, crystal oscillator 21, and integrated circuit 2. The display panel comprises glass plates 9b, h carrying electrodes and enclosing liquid crystal material. The display is of the twisted nematic type and includes polarizing plates 9a,k and a reflecting layer 9m. The rear polarizer and reflector are attached by adhesive at the periphery only. The reflector 9m is printed, e.g. with calendar data, in several colours and the display is assembled together with a colour filter (31), Figs. 17, 18 (not shown) and a mask, 30, in a watch case which is readily dismountable.

Abstract: 1319640 Carburettors SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 26 Aug 1970 [5 Sept 1969] 40985/70 Heading F1B An I.C. engine driving an alternator A, has a frequency meter 52 to determine the engine speed by measuring the frequency of current produced by the alternator which controls normally inoperative means regulating the fuel/air mixture supplied by a carburettor when the engine speed indicated by the frequency meter exceeds a predetermined value. The control means comprises a channel 12, valve 13, channel 14, levers 19, 22, rods 21, 23, diaphragm 24 channel 26 and valve 27. When the engine is decelerating from a speed greater than the predetermined speed, the vacuum produced in a space 25 causes a lever 19 to move to the left to prevent full closure of throttle member 2 and open a valve 13 which allows a portion of air-fuel mixture produced in channel 6 supplementary to that of orifices 8 and 11 to pass through channel 14. When engine speed has dropped to the predetermined value, electromagnet 30 is de-energized, closing valves 13 and 27, and causing closure of the throttle member 2. With open throttle at high speed no vacuum is produced in space 25 so valve 13 remains closed. In another embodiment, Figs.4 and 5 (not shown), lever 19 and vacuum unit are omitted and the electromagnet (30a) acts directly on a valve which controls the passage of air from upstream of throttle member 2 and air-fuel mixture to a point downstream of member 2.
