Title: Means and method of controlling wing tip stall in airplanes
IPC: B64C21/02
Filed: 1948-03-01
Abstract: 653,854. Controlling aircraft. DEHN, S. G. (Northrop Aircraft, Inc.). March 31, 1948, No. 9117. [Class 4] An aircraft having swept-back wing panels is provided with an automatic lift increasing slot adjacent the leading edge of the tip portion only of said wing panels, upper and lower closures for each of said automatic slots, and slot control means for simultaneously opening and closing all of said closures at predetermined lift co-efficient values. The upper and lower surfaces 12, 11 are connected by a slot 10, bounded by walls 13 of which the rear wall is spaced from the upper and lower surfaces to accommodate hinged flaps 14 and 15 when retracted from the normal positions which they occupy when closing the slot openings in the wing surfaces. The closing flaps 14, 15 are actuated by a plurality of links 21, 22 connected to bellcrank levers 20 in turn connected to an operating rod 25. One link 20a, Fig. 3, is extended and coupled by a pivoted arm 26 to the piston rod 27 of a hydraulic jack 28 which is controlled by a solenoid operated hydraulic valve 30. The jack holds the flaps closed against the action of a spring 31 so that in the event of a power failure the flaps 14, 15 may be opened by the spring. Adjacent each slot are two pressure switches (Fig. 4, not shown), each comprising a hollow box housing a pair of bellows connected by rods to a micro-switch external of the box. The bellows are respectively connected by tubes to the exterior upper and lower wing surfaces and the interior of the box is connected to a further tube facing forward on the lower wing surface to act as a pressure head so that differential pressures enable the bellows to operate the respective switches at pre-determined lift co-efficients of 0.6 and 0.7 and under normal conditions an automatic control circuit is arranged to open the flaps on port and starboard wings when a lift coefficient of 0.7 is reached on either wing and to close the flaps when the lift co-efficient on both wings is reduced below 0.6. In addition to automatic operation the flaps may be actuated by a switch under the control of the pilot and an emergency switch is incorporated in the automatic circuit to ensure that the flaps are opened by the operation of lowering the undercarriage.

Patent GB-578915-A (GB)
Title: Improvements in or relating to electric insulating materials
IPC: H01B3/44
Filed: 1942-07-03
Abstract: Electric insulating material, particularly for insulated wire or cable, containing rubber and polystyrene, but not vulcanizing ingredients, is heated, without mechanical working such as milling, to at least 90 DEG  C. for a time sufficient to cause substantial hardening of the material but insufficient to decompose it.  The term "rubber" includes unvulcanized natural rubber, cyclised and synthetic rubber, as well as mixtures of these; and the term "synthetic rubber" includes polymers of butadiene or substituted butadiene, copolymers of butadiene and styrene, copolymers of an olefine and diolefine and linear substantially saturated hydrocarbon polymers, e.g. polyisobutylene.  In examples, the treatment is described of compositions comprising polystyrene, crepe rubber, polyisobutylene and polyethylene alone, or paraffin wax together with (a) polyethylene, (b) talc or (c) zinc oxide.  In another example, the processing of a mixture of a copolymer of butadiene and styrene, polystyrene, polyisobutylene, polyethylene and paraffin wax is described.  Specification 577,943 is referred to.
Patent GB-293404-A (GB)
Title: Improvements in means for automatically stopping trains or the like
IPC: B61L3/04
Filed: 1927-04-05
Abstract: 293,404. Jones, O. C. - April 5, 1927. Fluid-pressure. - A venting valve mechanism for the train-pipe of fluidpressure brakes of railway vehicles of the kind comprising a spring-pressed valve adapted to be unseated by the passage over a ramp of a rod connected thereto and in which an electromagnet and a switch therefor are associated with the signal operating mechanism through the ramp so that the train-pipe is vented and the brakes applied at a " danger " signal comprises, as applied to a vacuum brake system, a valve b connected to the ramp actuated rod a' and to a diaphragm f<1> forming one wall of a normally exhausted chamber f which communicates by a restricted port l in a valve i<1> with a chamber h connected to the train-pipe d and by means of a passage e with the underside of the valve b. The space above the valve b is open to atmosphere by the port c. The valve i<1> is carried by the armature i of an electromagnet k. If the train passes a ramp at a " clear" signal, the magnet k is energized and the valve i<1> is thus lifted so that equalization of the pressures above and below the diaphragm f<1> is at once effected when the valve b is lifted by the ramp and the valve b re-closes under the action of the spring g without effecting an application of the brakes. The end of the passage e is formed as a nozzle e<1> and the armature i as a baffle plate whereby the momentary rush of air which takes place through the opening c and the passage e is prevented from entering the train-pipe and tends to delay the closing of the valve i<1> after the magnet k is de-energized. If, however, the signal is at " danger " when a ramp is passed, the magnet k remains de-energized and the valve i<1> closed. The upward movement of the diaphragm f<1> which takes place when the rod a<1> and valve b are lifted, expels air that may be contained in the chamber f through the valve i<1>, which then immediately re-closes and permits equalization of pressure into the chamber only through the restricted port l so that the valve b remains open for a sufficiently long interval to effect the application of the brakes. The rush of air past the port l through the nozzle e<1> tends to delay the flow of air into the chamber f and thus the closing of the valve b. For an automatic compressed air brake system, the train-pipe is connected to the opening c and the left hand end of the chamber h is open to the atmosphere. Specification 251,767, [Class 105, Railway signals &c.], is referred to.

Title: Improvements in or relating to internal combustion engines and to the charging thereof
IPC: F02M69/00
Filed: 1936-04-14
Abstract: 478,471. Two-stroke engines. FITZGERALD, W. M. B., and RATCLIFFE, T. April 14, 1936, No. 9355/37. Divided out of 478,422. Drawings to Specification. [Class 7 (ii)] In the engine described in Specification 478,422, the underside of the working piston acts as the charging pump, the charging of the combustion chamber 13, which need not however be immovable, from the same, or another cylinder is completed during the working stroke in that cylinder, the charge being held in the chamber 13 prior to ignition, and the entry valve into the duct 11 opens when the pressure therein is reached by the pressure beneath the piston. The fuel may be supplied to the chamber 13 or the duct 11 ; alternatively it may be drawn into the pump with the air. In a radial-cylinder engine the combustion chamber of one cylinder may be charged by the underside of the piston of the next cylinder in the firing order. In a multicylinder engine, in which the cylinders can be divided into pairs firing at intervals of 180‹, each pair may have a common duct 11 connected by valves to the respective chambers 13 and the pump spaces. The engine may be operated with petrol, heavy fuel oil, or gas by cooling the duct 11 as described in Specification 478,422 and compression ratios of from 10 or 16 to 1 may then be attained. It may, however, be operated as a Diesel engine by injecting fuel into the chamber 13 ; the duct 11 is then kept hot by surrounding it with insulating material or exhaust gas. An annular space round the base of a trunk piston may serve as the compression space of the pump.

Title: Improvements in wrapper patching method and mechanism for cigar making machines
IPC: A24C1/32
Filed: 1931-03-28
Abstract: 375,790. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) March 28, 1931, No. 9512. [Class 130.] A finishing patch which is applied to the tip of a cigar is cut from the same leaf as the wrapper. During the cutting of a wrapper W, a small patch P is cut from the leaf by a die 22 which surrounds a patch plunger 19. The wrapper and the patch are held by suction on a head 13 and a plunger 19 respectively, and these parts are raised into the positions 131, 191 where the suction is out off. The patch is removed from the plunger by a carrier 44 mounted on an arm 25 which is moved into a position 251 before the head 13 and plunger 19 are raised. A strong suction is applied through the carrier to remove the patch from the plunger and when the arm 25 is rotated the suction is reduced to that necessary to retain the patch P on the carrier. Each patch P is timed to arrive at a stand 57 at the same time as a cigar, cut from the same leaf, is ejected from the wrapping mechanism. Pressure of the cigar against the patch carrier 46 cuts off the suction and the patch adheres to paste previously applied to the cigar.
Patent GB-335268-A (GB)
Title: Improvements in or relating to gear-changing apparatus
Filed: 1929-03-25
Abstract: 335,268. Ruck, Sir R. M. March 25, 1929. Controlling variable-speed gearing.-Relates to controlling-means for variable-speed gearing for use on vehicles, consisting in voluntarily controllable automatically-acting power-operated step-by-step gear-changing apparatus. Instead of the stepwise-moved moin slider and cam plate described in Specification 244,583, there is a star-wheel 54, Fig. 1, and a revoluble shaft 55 with gear-striking cams 64, 65 splined thereon. Springs 74 allow the striking means 77 &c to act when the teeth of gears 62 &c. permit. The geardriving shaft 36<a> passes through a sleeve 35 constantly driven from the engine, and this sleeve, through gearing 32, 29, constantly drives the shaft 21 of the main cam 53. The cam 53 acts always in the same direction upon pawls 47, 50, Fig. 2, which engage it alternatively so that pawlarms 48, 51 can engage and turn the star-wheel 54 one step in one direction or the other. Other arms 49, 52 upon the pawls engage levers 56, 57 upon a shaft 60 which, through a linkage 156, Fig. 1, disengages the engine clutch C every time. A spring ball in a case 94 locks the star-wheel after each step. The three-arm pawls 47, 50 slide upon, rock-shafts 36, 37 Fig. 2, which are turned inwards towards shaft 21 by a spring 44, Fig. 6, when locking-levers 105, 106 are alternatively moved outwards to release catches 113, 114. Thus, when a release bar 126 is moved endwise, a catch is released and a three-arm pawl is engaged and moved by the main cam 53. After each step, the moved rock-shaft is returned by cam 119 or 120 to a position when the released catch 113 or 114 may re-engage. Steps succeed one another until release bar 126 returns to neutral. The bar 126 is connected by a lever 134, Fig. 1, to a shaft 139, Fig. 7, secured to a handle 145 which moves over a. quadrant 141. This quadrant is connected by a. tube 140 and gearing 144, Fig. 1, to the selector shaft 55. When handle 145 is moved, the change thus initiated is effected by power so that the quadrant 141 follows the handle 145. Direct hand-operation of shaft 55 may be effected from a handwheel 152, Fig. 7.
