Title: Improvements in and connected with multi-engine drives
IPC: B64D35/08
Filed: 1940-10-31
Abstract: 544,947. Driving-gear; clutches. DAIMLER-BENZ AKT.-GES. Oct. 31, 1940, No. 15923. Convention date, Oct. 18, 1938. [Class 7 (ii)] [Also in Groups XXIV and XXXIII] In a multi-engine shaft drive, particularly for airscrew shafts, in which each engine is coupled to the shaft by a clutch that is automatically disengaged when the speed of the engine is less than that of the other engines, the clutches can be adjusted to dis-engage either in the event of a minor engine disturbance, such as the interruption of the ignition or a defective fuel supply, or only in the event of a major disturbance such as fracture or corrosion. As shown, each engine 2 drives the airscrew shaft 6 through gears 4,5 and an over-running clutch 8a, 8b, the member 8b of which is carried by a shaft 14 slidably splined in the gear 4. The teeth of the clutch, Fig. 3, have inclined front faces 9, driving faces 10 parallel to the axis of rotation, and side faces 11 inclined to the axis. A clutch spring 23 is interposed between flanges on the shaft 24 and on a sleeve 16 slidable in the casing 13, and a second spring 24 is interposed between the flange of the sleeve 16 and a shoulder in the shaft 14. An adjusting lever 19 is provided with a pin 18 engaging holes in the sleeve 16 and a slot 17 in the stem of a plunger 15. The lever 19 is movable into three positions, in which (i) the clutch is dis-engaged; (ii) the clutch is engaged and loaded by the spring 23 only, so that it is readily dis-engaged by an engine disturbance ; (iii) the clutch is loaded by both springs 23, 24 and dis-engaged only by a serious engine disturbance. In place of loading springs 23, 24, a regulatable electric, hydraulic or pneumatic force may be used, or hydraulic, electro-magnetic or other couplings may be used in place of toothed clutches. The loading of the clutches may also be regulated in a stepless manner, or automatically in dependence upon engine speed or other engine function. The airscrew shaft 6 may have an extension which drives a cooling blower, cooling-water pumps, feed pumps, or a lighting generator.

IPC: C08G77/26
Filed: 1962-04-26
Abstract: A siloxane elastomer-forming composition comprises a peroxide curing agent, a filler if desired and a high molecular weight siloxane polymer containing units of the formulae [NC(CaH2a)Si(R)O]x, [R12SiO]y and/or [R112SiO]z, wherein x, y and z represent the weight percentages of the respective units, with x being at least 0.2, y + z being greater than zero, and the sum x+y+z being equal to 100; a is 2, 3, 4 or 5, and the -CN radical is separated from Si by at least 2 C atoms; R and R1 are each a monovalent hydrocarbon radical free of aliphatic unsaturation and contain 1 to 10 C atoms; R11 is a monovalent saturated or unsaturated hydrocarbon radical of 1 to 10 C atoms, the siloxane having been made by mixing at 100 DEG  to 170 DEG C., in the presence of a basic polymerization catalyst, polysiloxane reactants consisting of at least 0.25 (wt. per cent) of [NC(CaH2a)Si(R)O] units and up to 99.75 (wt. per cent) of [R12SiO] units and/or [R11SiO] units.  The polymers are made by co-equilibration of suitable linear (preferably hydroxyl-terminated) or cyclic siloxanes, the catalysts specified being Na, K and Cs hydroxides and K, Cs and (CH3)4N-silanolates. Fillers specified are C black, SiO2, esterified SiO2, ZnO, Fe2O3, TiO2, Al2O3, CaCO3 and ZnSiO4. Curing catalysts specified are di-t-butyl-, di-cumyl-, di-benzoyl- and tris-dichlorobenzoyl-peroxides, and t-butyl-peracetate and -perbenzoate.  The gum stock, without the catalyst, may be pre-cured by heating at 120 DEG  to 300 DEG  F. for 1 to 2 hours to cause wetting of the fillers by the gum and to eliminate volatiles, the catalyst is then added and the stock replasticized as by milling, and the composition is then mould-cured and, if desired, post-cured. Examples are given describing the above preparation of the polymers and elastomers therefrom.

Abstract: 402,482. Cylindrical journal bearings. AUSTIN MOTOR CO., Ltd., and LINDSAY, F. E., Northfield, Birmingham. June 10, 1932, No. 16391. [Class 12 (i).] In a bearing in which curved wedge - shaped spaces to contain oil are formed at the inner periphery of the bearing between the curved faces of a series of blocks and the journal, the blocks are mounted in guides in such a manner that they may be moved towards and from the axis of the bearing. The blocks B, which have a T- or L-shaped head, slide in grooves in the bearing carriage tangential to the journal, and to obtain curved surfaces b<2> and wedge-shaped spaces m may be initially set at a position inwards of the normal position, bored to a diameter larger than that of the journal, and set back a short distance by inserting a skim plate J under each block head. A set pin C clamps each head b to a face a of the carriage, and, on unscrewing, pushes a cover plate D secured by a pin d to effect the movement of the block. Oil is supplied to the bearing faces through passages, not shown, in an end cap F secured by pins H against the carriage face which is scraped or machined level with the blocks. The blocks may be mounted radially with respect to the axis of the journal and bored to a diameter greater than that of the journal, being then set inwards to form the wedge shaped spaces. By giving the journal and the curved faces of the blocks a taper, a correct fit by endwise adjustment may be obtained and the bearing may be made to take a certain amount of end thrust. In the Provisional Specification it is stated that the blocks may be adjusted and held by screws or wedges instead of the T- or L-shaped heads.

A heat exchanger comprises an inner tube 9 within an outer tube 10, one of which is of flexible material such as rubber, plastics, lead or copper, or of flexible metal hose, the heat exchange media flowing within the inner tube and between the tubes respectively, and the tubes being arranged helically inside and coaxial with a liquid-tight tank 11. In the form shown in Fig. 1 cold water flows into the tank at 1, and at 6 enters and passes through the space between the tubes, being discharged after heating through a connection 2. Heating fluid flows from an inlet connection 3 through the inner tube 9 to an outlet connection 4. The outlet end of the inner tube 9 is coiled around a thermally sensitive element 7 which activates a valve 8 regulating the flow of heating medium through tube 9. In another embodiment, Fig. 2 (not shown), water to be heated fills the tank after passing within tube 10, and the tube 9 is coiled around the element 7 at its inlet end. The heat exchanger may be used also as a steam condenser or as a brine cooler. When used as a steam condenser, the steam flows through the inner tube. When used as a brine cooler the coolant flows through the inner tube.
