Title: Improved aeroplane
IPC: B64C3/38
Filed: 1935-11-16
Abstract: 455,462. Aeroplanes. SOC. DES AERONEFS MIGNET, 11, Rue du Palais, Meaux, Marne, France. Nov. 16, 1935, No. 31805. Convention date, April 26. [Class 4] In a tandem-wing aeroplane in which two wings of adjustable incidence are disposed behind a propeller and at different levels so that a variable gap is left between the wings, a control device is provided which is adapted to vary the angle of incidence of both wings and which only over part of its operating range reduces the angle of incidence of the rear wing and either increases the angle of incidence of the front wing or leaves it unaffected. As shown, wings 2, 4 are articulated to an aircraft fuselage. The incidence of the wings is simultaneously adjusted from a control 6 through links 10, 11 by means of cam slots. The length of the link 11 is adjustable through screw-and-nut mechanism. In a modification, the rods 10 are guided and the plates 8 are adjustable. Guide rods may replace the slots. In a further modification, the link 11 is adjustable from a control 15, Fig. 10, and is connected by a link 14 to the rod 10. The above controls may be combined with gear sectors 17, 18 such that transverse movement of the control 6 effects differential movement of the wings on either side of the aircraft and in this case transverse movement of the control adjusts, in addition, through a cam slot 21 a rudder 20. The control member is arranged, when moved forwardly or rearwardly from its mid-position to initially reduce or increase the incidence of the front wing leaving the incidence of the rear wing substantially unaffected, when moved further towards the rear to decrease simultaneously the incidence of both wings and when moved further forward to increase the incidence of the front wing and reduce that of the rear wing.

Title: Improvements in and relating to current transformers for protective systems for electric apparatus
IPC: H01F38/30
Filed: 1920-11-10
Abstract: 174,475. British Thomson - Houston Co., Ltd., and Holbrook, H. S. Nov. 10, 1920. Regulating transformers.-In a circulating- current protective system for transformers or other electrical apparatus, in which current transformers with balanced secondary currents are placed on each side of the apparatus to be protected, the core cross-sections of the current transformers are made inversely proportional to the respective primary ampere turns under working conditions. The effective lengths of the magnetic circuits are made directly proportional to the primary ampere turns by providing one or more air gaps in the magnetic circuits. In the construction shown, the transformer core has an adjustable main air gap 2 and smaller gaps 3. The primary and secondary windings 8, 9 surround the main gap 2 in order to shield it from external influences. In a modification, the single main gap is replaced by a number of short gaps.

Abstract: 505,667. Bearings. COVENTRY GAUGE & TOOL CO., Ltd., HARLEY, S. J., and WAINWRIGHT, J. E. Nov. 23, 1937, No. 32185. [Class 12 (i)] Axial displacement of a spindle in its bearings is prevented by magnetic or electromagnetic means arranged either to operate in the same direction as the thrust and hold the spindle against a fixed stop, or to maintain the spindle in a pre-determined position against any tendency for it to move axially in either direction. As shown, the spindle a, Fig. 3, is held against a fixed stop g<1> by the magnetic attraction of an electromagnet j acting on the spindle end a<1>. The air gap between the parts a<1>, j, may be varied by a screw l. A permanent magnet, or magnetic repulsion may be used instead of magnetic attraction. To hold the shaft a, Fig. 1, against movement in either direction it is provided with a laminated disc d arranged between a pair of electromagnets b, c, supplied with alternating current. The windings b<1>, c<1>, are in parallel and the current in each may be varied by use of a variable resistance. A double thrust stop g may be used in addition to the magnetic bearing;

[Class 121] [Also in Group II] In a plant for separating starch from starch slush, fibres and fruit water using the centrifugal apparatus described in Specification 588,313, [Group II], the separated parts such as liquid, fibres and starch slush are subjected to further treatment for starch recovery. Raw starch is fed to a vibrating screen system 1, the pulp 1b being removed, the remainder, the starch milk, is led to two parallel-coupled concentrator bowls 2 from a collecting tank 14. The concentrated starch is dischaged though nozzles, in the bowls 2, and led through a pipe 4 to two parallel purifiers 5, which are of the kind shown in Specification 588,313, [Group II], where the starch slush, fibres and fruit water is separated out. Wash water is supplied through a pipe 3 to the bowls 2 and the purifiers 5 and leaves through pipes 2a, 6 respectively. Pure starch is led away through an outlet 5a. Wash water and its contents leaving through the pipe 6 pass to a strainer 7 where the fibres 7a are discharged, the remainder entering a concentrator 8 which has a wash-water inlet 3. The concentrated liquid passes through a pipe 9 to a vibrating screen 10 where fibres 10a still remaining are eliminated, the residue being led to one or more purifiers 11. Pure starch from the latter joins that obtained from purifiers 5. The remainder may be further processed to extract starch. Settling tanks may be used in the plant. The plant may be operated partly automatically and partly by hand operation.

Type-wheel machines; type-band machines; type-bar machines; hammer-impression mechanism; electric signal input arrangements.- A high-speed selective printer used for output units of data processing machines and having types mounted on a rotary-type carrier, a chain or type bars, is provided with an electromagnetically operated drive mechanism for a plurality of hammers 1 comprising a corresponding plurality of electromagnets 11 for each of which the print hammers 1 are adapted to form an armature in that the hammers carry two armature yokes 12, 13 of soft magnetic material, said electromagnets exerting on said hammers a force in the impression direction. Each hammer 1 comprises a bar of rectangular cross-section having a hammer head on its front end and the hammer is mounted on a pair of leaf springs 3, 4 serving also to return the hammer to its rest position after impression. The hammer also carries two U- shaped armature yokes 12, 13, the polar surfaces 14 are inclined and co-operate with like polar surfaces 15 of the electromagnet 11 having coils 16, 17 energized with current pulses J2 and J1 respectively. The pulse J1 is of short duration but higher amplitude, whereas the pulse J2 is of longer duration and is ineffective by itself to displace the hammer into its printing position. For impression, both coils 16, 17 are energized simultaneously by said pulses J1 and J2, but when the short pulse J1 terminates on completion of impression the pulse J2 produces a magnetic force retarding the return movement of the hammer, thus preventing rebound. The return movement is limited by a buffer stop 9 having a mass equal to the hammer 1 and clamped to an elastic separator 10.

[Class 75 (iv).] Lantern screens. -In a vehicle lamp with a coloured, translucent, cylindrical screen 10 adapted to be moved into and out of operative position in relation to the lamp bulb 2, the screen has zones of different colours so that it causes the reflector to project lateral beams I of a colour such as orange well adapted to penetrate fog, and a slightly yellow or white beam II which is thrown on to the road in front of the vehicle. The screen may also colour the part III of the beam which is thrown upwardly another colour, e.g. green, or the screen may have an orange zone and a yellow or white zone separated by narrow violet zones. The screen 10 slides into and out of a socket 3 at the back of the reflector 1, and is guided by a fixed rod 11 passing through holes in the front ring 12 and the shank of a fork 9 attached to the rear ring 20 of the screen 10. The fork 9 is engaged by a stirrup 8 fixed to an armature 6 pivoted at 21. The armature is moved by the electromagnets 4, 5, and is held in one or other of its extreme positions by engaging in a notch 15 in a lever 14 associated with each electromagnet.
