Title: Improvements in or relating to aircraft controls
IPC: B64C9/22
Filed: 1940-04-30
Abstract: 539,532. Controlling aircraft. TAMPIER, R. J. C. April 30, 1940, No. 7738. [Class 4] [Also in Group XXX] A movable surface at the trailing edge of an aeroplane wing and movable rearwardly is slidingly supported in a guide on a fixed housing for a propeller shaft projecting rearwardly of the wing. On each side of the aircraft is a propeller 8 driven by a shaft 17 in a housing 21 projecting beyond the rear edge of the wing, the shaft 17 being driven by gearing 18, 19, 20 on three parallel shafts driven through a gear box from a separate engine in the fuselage. A movable plane 3, normally nested beneath the trailing edge of the wing is carried by a block 22 moving along a dovetailed guide beneath the housing 21. A plane 5 at the leading edge of the wing may be projected forwardly separately or simultaneously with the rearward movement of the plane 3. A hinged flap 6 also may be opened separately or simultaneously with the rearward movement of the plane 3. The plane 3 is movable by a rack 42 and pinion 44, Fig. 4, the plane 5 by a rack 43 and pinion 45, and the flap 6 by a worm 59 and worm wheel 61 all actuated from a countershaft 54 through clutches 57<1>, 58<1> and 60. The countershaft 54 is driven through reversing gearing from a shaft 46 driven from the shaft 17 through a clutch 49. In an emergency the shaft 42 may be driven by a reversible electromotor 120 through a clutch 121. Limiting devices actuate the clutches 57<1>, 58<1>, 60 when the respective planes reach the limit of their movement in either direction, or actuate switches controlling the electromotor, and means are provided enabling the clutches to be re-engaged when required. In a modification the plane 3 is moved by a screwed extension of the shaft 54 which also drives through worm gear the pinion for actuating the plane 5. The guide for the plane 3 may be downwardly inclined towards the rear in which case the screwed shaft is cardan jointed to the shaft 54. An aileron 4 is carried by the plane 3 but is only movable when the latter is in its forward position the aileron becoming locked when the plane 3 is moved rearwardly. For this purpose an aileron control hinge 78. Fig. 7, such as is described in Specification 496.875, actuated by a rack 76, may be used. The rack is coupled by a pin 85 and bayonet slot 86 to a sleeve 81 movable by a rod 77. The sleeve is rotatable by a quadrant 87 and pinion 88 to uncouple the rack, and simultaneously a sleeve 80 on the rack rod is turned by a finger 84 to bring a projection 89 on the sleeve between spring stops 90 to immobilize the aileron. Mechanism as described in Specifications 494,579 and 499.503 may be used instead of the hinge mechanism 78. When the ailerons are out of action the front planes 5 may be used as described in Specification 539,117 for lateral balancing. Specification 538,046 is referred to in the Provisional Specification.

Patent GB-234585-A (GB)
Title: Improvements in and relating to processes for the production of potassium carbonate
IPC: C01D7/07
Filed: 1924-04-01
Abstract: A process for the production of potassium carbonate of a desired degree of purity consists in treating a caustic potash solution with carbonic acid for such a length of time, which is greater or less according to the degree of purity desired, that only a part of the potassium hydroxide is converted into carbonate, leaving sufficient caustic potash in solution to retain the impurities contained in the original liquor.  When a concentrated solution of potassium hydroxide of about 45 DEG  B<\>ae. is employed, pure potassium carbonate is precipitated until about 40-50 per cent of the hydroxide has been converted into carbonate.  The precipitated carbonate is separated at this point, beyond which, dissolution commences if the process is continued.  Potassium carbonate of a lesser degree of purity may be obtained by continuing the process beyond the point at which dissolution of the precipitated potassium carbonate begins, and subsequently separating the carbonate by evaporation and cooling. The process may also be adapted to the purification of impure potassium carbonate by treating it with a caustic potash solution of about 45 DEG  B<\>ae. and passing carbonic acid.  The carbonic acid treatment is preferably carried out at a temperature of about 10-15 DEG  C. in order to increase the yield.

Title: Improvements in or relating to mechanical transfer mechanisms
IPC: B23Q7/14
Filed: 1967-02-22
Abstract: 1,119,008. Transferring workpieces. CROSS CO. 22 Feb., 1967 [9 March, 1966], No. 8518/67. Heading B3B. A transfer mechanism for transferring workpieces between workstations at which machining or assembly operations are carried out comprises a transfer arm pivoted.at one end about a first axis and pivotally and slidably connected to transfer bar means which are longitudinally reciprocable in a direction normal to the first axis, multi-speed rotatable drive means interconnected with the transfer arm by crank means whereby the transfer bar means is reciprocable at a relatively high rate initially and thereafter more slowly to transfer workpieces smoothly arid position them accurately at the end of each movement in the longitudinal direction. A work supporting pallet 27, Fig. 1, is mounted on rails 23, 25 for sliding transfer movement under the control of a reciprocable transfer bar 29. The bar 29,is oscillatable about its own axis under the control of an hydraulic motor 53 and transverse slide 61 to bring;driving dogs 45 on the transfer bar 29 into and out of driving engagement with the pallet 27. Longitudinal movement of the bar 29 in suitably timed relation with the oscillation thereof is effected by means of a reversible two speed drive motor 85, Fig. 4, which operates through a crank 117 and pivoted transfer arm 127 to reciprocate a drive block 83 mounted on the transfer bar 29. Movement of the crank 117 is limited to 180 degrees by limit switches 176, 192 engaged by members mounted on the transfer arm 127, the major portion of this movement being effected with the motor 85 running at high speed; the final portion of the movement is determined by switches 177 or 178 operated by cam members 171 or 185 mounted on the crank 117 and is at low speed. The effect of the speed switching and of the simple harmonic motion derived from the crank is to provide optimum acceleration and deceleration -and accurate positioning of the workpiece and pallet during transfer from one station to the next. The pivot mounting 129, 132 of the transfer arm is adjustable in position in two directions to provide adjustment of the stroke and end points of the movement of the transfer bar. In a modified form of the invention (Figs. 11-15, not shown) there are two transfer arms interconnected in such manner by a pivotal link that one arm, which is operated directly by the crank, performs a movement twice the magnitude of that of the other. In this embodiment the transfer bars are raised and lowered selectively by hydraulic rams to bring them into and out of their operative position for transferring pallets. The second transfer arm and its associated transfer bars transfers pallets singly once each cycle through one station while the first operates once each alternate cycle to transfor pairs of pallets through the distance of two stations.
