Abstract: 573,127. Helicopters. DALRYMPLE, A. W. H., and LINDSLEY, F. Dec. 3, 1943, Nos. 20265/43 and 4326/44. [Class 4] A helicopter of the type in which the sustaining rotor is positively driven by a prime mover about an upright axis transverse to the fuselage, is controlled in flight by a thrust-producing device, such as an airscrew or reaction jet, located at the tail of the machine and mounted in such a way that the line of thrust can be set at varying angles. In one form, the engine and propeller shafts are in line, connected together by a universal coupling, while in a second embodiment bevel gearing is interposed between the two shafts, the gearing being carried on brackets capable of rotation about horizontal and vertical axes. In the arrangement according to Fig. 4, the airscrew shaft 6 is driven from a parallel shaft 4 through bevel gearing carried by brackets 19a, 20a, which are rotated about perpendicular axes D-D, C-C, respectively, by links 47, 54, 56, 58 and 47, 49, 51, 52. The links 51, 56 are interconnected by a pivot member 57 so arranged that actuation of the pitching control member 52 does not cause rotation of the bracket 19a about the vertical axis D-D. Fig. 5 shows a reaction nozzle 68 mounted through the medium of a flexible hose coupling 69 on the tail of the machine, universal movement being imparted by control members connected to pairs of vertical and horizontal arms on the nozzle. According to the Provisional Specification, the jet may discharge through orifices arranged around a central conduit, and controlled by shutters. The shutters may be operated in such a manner that as any orifice is closed, the diametrically opposite one is opened. A number of separate nozzles may be provided, each capable of tilting movement in the radial plane.

Title: Improvements in or relating to locks
IPC: E05B67/10
Filed: 1922-07-25
Abstract: 206,200. Wheeler, F. July 25, 1922. Padlocks; locks, controlling operation of; sliding latches, preventing operation of; bolts.- In locks having two bolts disposed in the same plane and operated by successive movements of a key with a single bit, one bolt acts as a blocking member for the other bolt and the rotation of the key is reversed for successive operation of the two bolts. One of the bolts protrudes from the casing for locking, and each bolt may have its own tumblers. The invention is illustrated as applied to a padlock, one bolt 5 serving to lock the shackle 2, and the other or blocking bolt 31 being arranged at right angles to, and in the same plane as, the bolt 5, Fig. 5, shows the padlock with the bolt 5 in its locking position 4, with the bolt 31 moved out of its blocking position by the key, the tumblers co-operating with the stump 9 on one side of the bolt 5 being removed, but a tumbler 11, coacting with a stump on the other side of the bolt, being shown. In unlocking, the key 18 is inserted and turned in an anticlockwise direction. During this movement, it moves tumblers pivoted at 43 and rocks the member 34 on its pivot 35, causing its arm 33 to pull down the bolt 31 from the path of the bolt 5, when the tumbler 40 pushes a pivoted catch 47 into a notch 48 in the bolt 31 to hold it in its withdrawn position. The key is then turned until it trips over the spring trigger 26 pivoted on the bolt 5. The key is then turned in a clockwise direction, lifting the tumblers acting on the stumps of the bolt 5 and withdrawing the bolt by means of the trigger 26 against its spring 22 which acts on the bolt arm 28. When the end of the bolt 5 is in the path of the bolt 31 so that this cannot rise under the action of its spring 36, a projection 48a on the bolt 5 strikes the arm 49 of the catch 47 to release it from the bolt 31 to allow automatic blocking on again shooting the bolt 5. When the bolt 5 is withdrawn and the shackle 2 removed from the hole 4 in the casing 1, a pivoted catch 16 enters a notch 15 in the bolt, under the action of the spring 17, to hold the bolt 5 withdrawn until the shackle is again pressed in for locking, when the bolt 5 shoots forward and the bolt 31 moves into blocking position. A catch 50 pivoted on the same pivot 23 as the tumblers governing the bolt 5 and having a spring 51, prevents clockwise rotation of the key if turned too far in the anticlockwise direction before reversal of its motion. The tumbler 40 serves to operate the pivoted catch 40, the tumbler 41, by means of its upper and lower pins 44 causing the tumblers 40, 41, 42 to move into their normal position under the action of the spring 45, and the upper tumbler 42 acts as a filling piece.

Title: Polymers of isopropenyl toluene
IPC: C08F36/04
Filed: 1943-12-07
Abstract: o-, m-, or p-isopropenyl toluene is polymerized by treatment at - 80 DEG  C. to 150 DEG  C. with a boron fluoride-ether complex made by passing boron fluoride into ether at atmospheric temperature or below until the product contains 45-47 per cent of boron trifluoride.  A continuous process may be used.  The product may be used as "seed" for inducing the polymerization of further isopropenyl toluene.  The polymers include dimers and trimers and may be liquid, pasty or solid.  They may be soluble in carbon tetrachloride, gasoline, benzene or cyclohexane.  Components of the polymer mixture may be separated by fractional distillation at low pressures or by extraction with methanol, propanol, isopropanol, tert.-butanol, acetone or methyl ethyl ketone.  The polymers may be nitrated, sulphonated, chlorinated or hydrogenated in the presence of a Raney nickel catalyst.  They may be formed into emulsions.  Compositions may include natural and synthetic rubber, waxes, e.g. paraffin, dyes, pigments, driers, fillers, plasticisers, drying oils, e.g. linseed or tung oil, natural resins and other polymers, e.g. polystyrene, poly p-methyl styrene and copolymers of isopropenyl toluene and styrene or p-methyl styrene prepared by heating to 100 DEG  C. for a week.  The products may be used as insulating oils, lubricants, e.g. in spinning, and pressure-sensitive adhesives, for hot-melt or solution coating or impregnating paper, textiles, leather and metal, and for making films.  The polymers or their hydrogenated products may be chlorinated and mixed with chlorinated diphenyls for use as dielectrics.

Title: Improvements in or relating to auxiliary air admission devices for internal combustion engines
IPC: F02D9/00
Filed: 1955-07-14
Abstract: 792,324. Auxiliary air admission devices. WAYMOUTH, H. July 11, 1956 [July 14, 1955], No. 20468/55. Class 7(2) A suction oper ated auxiliary air inlet valve is controlled by a diaphragm and is operable through a range in which it is open between two extreme positions in each of which it is closed resilient controlling means urging it towards one extreme position against the diaphragm which is also urged by resilient means against the valve. As shown a chamber 13 is in communication with the atmosphere through a passage 31 or is connected to the engine side of the air filter. When the valve 25 is moved away from its seat this chamber is connected through an annular space 33 and port 35 to a passage 16 leading to a perforated pipe (not shown) extending across the induction passage. Port 19 communicates with the interior of the manifold. When the engine is cold a thermosensitive device 38 conveniently a bimetallic strip holds open an air inlet valve 21 so that the chamber 12 is in communication with atmosphere and the valve 25 is seated. As the engine warms up the device 38 releases the spring 37 and allows it to close the valve 21. Suction in the chamber 12 then opens the valve 25. As soon as the valve opens pressures tending to hold the valve closed are removed and the valve is moved appreciably. When the throttle valve is returned to idling position the valve 25 is moved to the right to the extreme limit of its movement and the extra air supply is cut off. On opening the throttle the suction is removed and the valve 25 is closed but as the engine accelerates the suction again opens the valve: If the valve 21 closes with the throttle at its minimum opening the engine may stall due to opening of the air valve 25. This stalling is prevented by making the strength of the spring 27 such that it cannot open the valve 25 against a high pressure difference on the head. When the throttle is moved to the fully open position the valve 25 closes. The guide 23 is rotatable to vary the effective length and area of opening of the air slot 35. A hand control 41 is movable over a fixed scale 42. A leaf spring 39 is coupled to the valve 25 so that when the valve opens it allows the spring 39' to reinforce the action of the spring 37.

Title: Preparation of alkyl aluminium dihalides
IPC: C07F5/06
Filed: 1956-07-03
Abstract: Alkyl aluminium dihalides may be prepared by reacting together an alkyl halide, metallic aluminium and aluminium halide in a one-step process.  The reagents may be used in approximately stoichiometric proportions.  If desired, the aluminium halide may be added in incremental amounts to a mixture of allyl halide, aluminium and aluminium halide.  The reaction may be carried out at temperatures between 20-200 DEG  C., at atmospheric pressure or at super-atmospheric pressures or in an inert liquid medium such as methyl cyclopentane or benzene.  A reaction initiator, e.g. methyl or ethyl bromide or iodide or a dialkyl ether may also be used. The desired alkyl aluminium dihalide may be separated from the reaction mixture by solution in an inert liquid organic solvent such as n-heptane or other inert hydrocarbon.  In an example aluminium metal fines and aluminium chloride are reacted with methyl chloride using methyl iodide as a reaction initiator.  The product, methyl aluminium dichloride was distilled under reduced pressure from the reaction product.

Filed: 1928-07-16
Abstract: 296,400. Westinghouse Brake & Saxby Signal Co.. Ltd., (Assignees of Speer, J. E.). Aug. 31, 1927, [Convention date]. Fluid-pressure operation; electric control.-The normal and reverse electromagnets 8, 8<a> are automatically de-energized when the points are fully set, the circuit of each magnet including a rectifier. The fluid-supply to the motors N, R is controlled by a motor L and lock magnet 59 energized by the pole-changer P which is actuated by the cabin lever S, the lock circuit including rectifiers 36, 40 and switches C<N>, C<R> which are closed except when the points are in reverse or normal positions respectively. Motor L when energized supplies fluid to motor 53 to withdraw a lock D from the point rod, the lock being forced home by a spring 55 when magnet 59 is deenergized. The circuits to magnets 8, 8<a> include the rectifiers 26, 34, and a switch 29 normally open but closed by the lock D, so that motors N, R can only be energized at the same time as motor L. Lock D also actuates switches 44, 46 which are normally closed and are in a circuit including a pole-changer K actuated by the point rod and an indication relay J, this relay being thus energized only when the points are fully home and locked. In a simpler form, without lock or indication, the switch C<N>, C<R>, actuated by the point rod, are in circuit with a rectifier and the magnet of the corresponding motor R, N, so that only two conductor wires extend between the control and the motors. Specification 257,305, [Class 37, Electricity, Measuring &c.], is referred to.
Patent GB-208766-A (GB)
Abstract: 208,766. Haddan, A. J. H., (National Cash Register Co.). Sept. 22, 1922. Cash registers with operating means; interlocking. - Relates to release mechanism for cash registers of the key-set independently-operated type, having a normally locked driving-mechanism and comprises a release key mechanism which is only operative after the manipulation of two setting means which successively operate, irrespective of order, a part of the release mechanism. The release mechanism comprises a pinch lever 50, Fig. 5, adapted for totalizer selection, a series of keys 12, Fig. 1, representing a tax and including a " no tax " Key, and a special release key 65, Fig. 2, so arranged that the release of the machine may be effected by their successive operation in the order named, or by depressing a tax key first. and then operating in succession the lever 50 and the key 65, whereby the shaft 78 is freed so that its subsequent oscillation may release the machine. When the lever 50 is pinched, the depression of a bar 51 rocks a shaft 52 carrying an arm 53 which breaks a toggle 55, 56, working on a fixed pivot 57 and a floating pivot 58, by raising the middle pivot 59 above the line of centres of the outer pivots. The toggle is now urged upwards by a spring 60 acting on an arm 61 which tends to rotate the shaft 62, and, through the link 105. the shaft 78, but oscillation is prevented by the engagement of an arm 100, Fig. 1, carried by shaft 78, behind an arm 87, the lower end of which engages an arm 90 rigidly mounted on a shaft 91. This shaft carries retaining-bars 92, one for each bank of tax keys, which are urged rearwardly by spring 95, but are normally held in a forward position by the engagement of detent plates 97 with notches in the bars. When, however, a tax key is depressed, the bar 92 moves rearwardly and a roller 98 engages an arm 99 on the shaft 91 and rocks it and the arm 90, thereby carrying the arm 87 out of engagement with the arm 100. Oscillation of the shaft 78 is still prevented by the engagement of a pivoted pawl 80, Fig. 2, carried by an arm 79, with a half-round stud 77 carried by the detent plate 73 of the special key 65. Depression of this key raises the plate 73 by engagement of a pin 70 with a slot 71, whereby the stud 77 clears the pawl 80 and becomes located between it and a second pivoted pawl 81. The shaft 78 is now free to oscillate, and the release of the machine is effected by the rocking of the shaft 62 by the spring 60. After each operation, the parts are returned to normal position as follows. A cam 102 on the shaft 24, which has one complete rotation at each operation, returns the toggle to normal, and this movement rocks the shaft 78, whereby the stud 77 re-engages the pawl 80 and the plate 73 drops and allows release of the key 65 by the spring 106. The arm 100 is also returned, and the bars 92 are returned by a cam arm 115 on the rock shaft 13 engaging studs 107 and are again held by detents 97. The rollers 98 are thus drawn clear of the arms 99, which are returned by the spring 108 and carry with them the arm 87.
