Abstract: 562,693. Controlling aircraft; planes. SAUNDERS-ROE, Ltd., BRENNAN, M. J., and KNOWLER, H. Dec. 23, 1942, No. 18294. [Class 4] An aeroplane wing of the kind comprising a wing-tip unit consisting of a number of elements of aerofoil section disposed one behind the other and slidable into the main wing, is provided with an aileron and a flap and the trailing element of the wing-tip is slidable into and partakes of the movement of the aileron to assist in the lateral control of the aircraft while the aileron is arranged to partake of the downward movement of the flap to assist in increasing the lift of the wing. As shown, the main wing comprises a nose-slat 16, a part 17, an aileron 18 hinged at 23 to the part 17, and a flap 69. The wing-tip unit comprises a nose element 11, an element 12 and a trailing element 14 connected to a fairing 15 and slidable respectively into the main parts 16, 17, 18 by means of guides 25-32 and rollers 24, 33, the element 14 being hinged at 22 to the fairing 15 so as to move upwards and downwards with the main aileron part 18. A shroud 13 is connected to the rear of the element 12 by parallel links 19 so as to be swung rearwardly from this element to the position shown to form an aerodynamic slot with the element 14, by the engagement of a hook 47 on the element 12 with a catch on the main wing part 17 when the wing-tip is extended the shroud being collapsed against the element 12 by a spring 46, when the tip is retracted. Retraction and extension of the wing-tip is effected by a shaft 35 rotatable by a motor and on which is spliried' a worm-wheel mounted on the element 12, the worm-wheel engaging a worm on a shaft 37 also carried by the element 12. The shaft 37 drives through bevel-gearing 38, 39, a pair of pinions secured to the respective spindles of the bevel gears 39 and engaging rack teeth formed on the guides 29, 30 provided on the wing part 17. The wing-tip is locked in the retracted position by a spring-pressed bolt 49 mounted on the guide 29 for engagement with a socket in the guide 27 and releasable by a solenoid. The datum position of the aileron may be lowered simultaneously with the lowering of the flap 69 by passing the aileron control cables 53, 54 around pulleys 55, 56, 57 and 58, 59, 60 respectively, the pulleys 56, 59 being adjustable by a screwed shaft 63 driven by a sprocket chain 65 from the flap-operating shaft 67. According to the Provisional Specification, the wing-tip elements when extended may be moved in a fore and aft direction or be spread from their roots in a fanwise manner or each element may be turned about its axis to vary its incidence.

Title: A process for the production of olefines by catalytic dehydrogenation of paraffin hydrocarbons
IPC: C07C5/333
Filed: 1936-07-02
Abstract: A process for the production of olefines by catalytic dehydrogenation of paraffin hydrocarbons comprises contacting paraffin hydrocarbons containing at least two carbon atoms or hydrocarbon mixtures containing one or more of such paraffin hydrocarbons, preferably in the vapour phase, with an activated alumina catalyst at an elevated temperature, e.g. 500--800 DEG  C., and under such conditions of contact time and pressure of operation that cracking is substantially avoided.  The activated alumina is produced by thermal treatment of alumina or aluminium hydroxide to render the resulting alumina porous, e.g. by calcining at 300--800 DEG  C.  In examples: (1) Dry propane is passed through a quartz tube packed with granules of activated alumina maintained at 650 DEG  C. for 4 hours; (2) Nitrogen is passed through a chromium-nickel steel tube packed with granular activated alumina which is heated to 600 DEG  C.  Dry isobutane preheated to 475 DEG  C. is then passed through the tube for 48 hours.  The reaction may be carried out at sub-atmospheric, atmospheric or moderately elevated pressures, in the absence of oxygen or water and in the presence of a diluent material, e.g. hydrogen, or a hydrogen "acceptor" such as ethylene.  The catalyst may be re-activated after use, e.g. by burning the carbon deposited thereon to carbon dioxide by passing air over the heated catalyst, if desired in the presence of steam, carbon dioxide and nitrogen, or by oxidizing the carbon with carbon dioxide or steam alone. The process may be intermittent or continuous.  The effluent gases can be denuded of olefines by contact with sulphuric acid, a sulphonic acid, phosphoric acid or sulphur dioxide, the denuded gases being recirculated over the catalyst.  The paraffin hydrocarbons &c. to be treated may be natural gas, cracked petroleum, mixtures resulting from the pyrogenetic treatment of shale oil, peat, asphalts and coals, technical olefine-paraffin-containing mixtures such as the propane-propylene cut, butane-butylene cut and pentane-amylene cut from which the olefines may be removed before treatment.  Motor fuels such as gasoline may also be treated by the process to increase the proportions of unsaturated hydrocarbons to saturated hydrocarbons therein.

Filed: 1974-04-26
Abstract: 1446139 Electric analogue calculating COMMISSARIAT A L'ENERGIE ATOMIQUE 26 April 1974 [4 May 1973] 18417/74 Heading G4G In electric analogue circuitry analogue amplitudes are stored in memory elements constituted by F.E.T.s having a number of layers of dielectric between the gate and the doped semiconductor substrate of the transistor, the amplitudes being stored in the form of threshold voltages. An example of the use of such an F.E.T. 36 is in a multiplication circuit 31 which is one element in a chain of similar circuits. The voltage stored in a circuit 38 is stored in the F.E.T. 36 while the voltages in stores 48, 50 are applied to F.E.T.s at their gates 46, 44, respectively, these F.E.T.s being connected in a differential mode. A pulse V 3  is applied to lead 42 to zero-set the transistor 36. An output signal is derived by comparing the currents in resistors 58 and 60 when a constant current is applied to 42. The Specification also describes the use of the store in integrating circuits which operate by summing the amplitudes stored in a plurality of stores.

Title: Improvements in and relating to electric circuit breakers
Inventor: BEDDOE STANLEY
IPC: H01H9/38
Filed: 1954-06-25
Abstract: 793,040. Automatic circuit-breakers; arcing- preventing in switches. ENGLISH ELECTRIC CO., Ltd. June 24, 1955 [June 25, 1954], No. 18705/54. Class 38 (5). A circuit-breaker has main contacts (not shown), auxiliary contacts 15 ... 17, means for operating the main contacts (not shown), a closing spring 26 for the auxiliary contacts and latch means for retaining the spring charged, the spring being charged and the auxiliary contacts opened during a closing operation of the main contacts and the latch being released on the initial opening movement of the operating means for the main contacts so that the auxiliary contacts are closed by the spring 26 before the main contacts open. Though the energy for closing the auxiliary contacts is provided by the main contact operating means and is used during an opening operation of the main contacts so that the opening of the main contacts is not retarded. An inductive load may be supplied through the main contacts, the auxiliary contacts closing a discharge circuit just before the main contacts open. In the arrangement shown, when the opening operation of the main contacts is initiated, a member 25 is caused to turn in the direction of the arrow and a pawl 20 is driven to cause a lever 19 to move anticlockwise about a pivot 18 and break a toggle formed by levers 19, 22. A lever 14 is then free to turn about its pivot 11 under the bias of the spring 26 which closes the contacts 15 ... 17. To avoid incorrect operation and to ensure that the closing of the auxiliary contacts is followed by the opening of the main contacts, a lever 33 is turned about its pivot 11 by the lever 22 as the toggle 19, 22 collapses. The lever 33 turns a lever 35 which turns a lever 38 to trip the main contacts. After the contacts 15 ... 17 have closed, the further movement of the member 25 permits a pin 24 to move along a slot 22a in the lever 22 so that no force is transmitted through the lever 22 and the toggle is reset by a spring 27b. The turning of the member 25 clockwise when the main contacts are reclosed restores the path to the position shown.

Title: Moulding refractory crucibles
IPC: B28B1/04
Filed: 1937-07-07
Abstract: 486,826. Moulding crucibles by shaking- machines. AMAND, R. July 7, 1937, No. 18870. Convention date, July 10, 1936. [Class 87 (ii)] Crucibles are moulded from a paste of electrically conducting material in the form of flakes, such as graphite, by filling a mould, having a core rigid therewith, with paste, subjecting it to a series of vertical shocks, then placing a weight on the paste and subjecting it to a second series of shocks, and finally detaching the core from the mould and applying a third series of shocks so that the core moves down and compresses the paste to a uniform density. The mould 1, which is attached to the table of a jarring machine by bolts 3, is provided with a cylindrical extension 6. The core 4 is hollow and has a valve 7 at its base to facilitate removal. The core is attached to an annular member 9 which is screwed to the extension 6 and spaced therefrom by distance pieces 11. The lower edge of the member 9 is bevelled at 9e. The mould is jarred during the filling operation and then the follower mass is placed on the material. This mass comprises a cylindrical member 12 and a top weight 14. The member 12 has vertical slots 13 and fits in slots in the annular member 9. The lower ends of the slots 13 are closed by T-shaped keys 15, Fig. 5, retained in position by pins engaging the holes 16. The second jarring takes place with the mass 12 in position.. Hydraulic pressure is then applied to the weight 14 to increase its effect by means of a piston 24 working in a cylinder 19. The piston is connected to the weight 14 by a key 25 and its stroke is limited by rods 23. As the final step the distance pieces 11 are removed and the mass 14 is connected to the extension 6 by bolts 26. The key 25 is removed so that the piston 24 bears on the core 4 and the jarring is restarted. The core then moves down until the member 9 reaches the extension 6. The mass 12 may be extracted by means of the hydraulic cylinder. In this case the cylinder 19 is slidable in a sleeve 20 so that when the fluid pressure is released the cylinder 19 falls. The nose 19a is then connected to hooks 27 on the weight 14 and fluid is readmitted. Since the piston 24 is retained by the rods 23 the cylinder 19 rises drawing the weight 14 upwardly. The Specification as open to inspection under Sect. 91 refers also to the moulding of hollow refractory bodies other than crucibles. This subject-matter does not appear in the Specification as accepted.
