Patent GB-853773-A (GB)
Title: Starch manufacturing process
Inventor: MEISEL HARRY
IPC: B01D29/00
Filed: 1957-09-30
Abstract: Starch is recovered from starch-bearing roots and stems by feeding the wet starch-bearing material into a high speed rotating rotor disc (the peripheral speed of said rotating disc being at least about 21,000 feet per minute) which imparts its velocity to the material and impinges it upon a surface, the impact of which is substantially normal to the direction of the material whereby the starch granules are released from the cells without shredding them nor the vascular fibres, subjecting the resultant starch-fibre-fruit water mixture to screening and washing operations to wash and separate the liberated starch from the fibre and further treating the resultant starch slurry for removal of residual fibre and solubles therefrom, as by starch tables or centrifugal means.  The apparatus used in the first step is an impact mill of the type described in Specification 811,686.  The washing and screening may be effected with a series of sieves and shakers but preferably a series of centrifugal screen pumps (see Group I) are used.  The washing may be done directly or in countercurrent manner.  The resultant starch slurry may be passed over conventional tables or through centrifuges for final purification but it is preferred to pass the slurry with counter current washing through a series of hydrocyclones.ALSO:The main subject-matter of this Specification pertinent to Class 46 is apparatus identical with that described in Specification 845,940; several such apparatuses may be arranged in series.  The claims are concerned with a starch recovery process.

Abstract: 855,961. Ejector seats for aircraft. M. L. AVIATION CO. Ltd. Sept. 25, 1957 [Oct. 10, 1956], No. 30893/56. Class 4. [Also in Group XXXIV] A gun for an ejector seat for aircraft comprises two, or, as shown, three telescopic tubes 1, 2, 3 wherein the inner tube 3 is secured at its lower end (not shown) to the aircraft structure and the outer tube 1 is secured to the seat (not shown). Tube 3 carries a cylindrical member 7 formed with a circumferential groove to accommodate a ring of balls 5 housed for radial movement in an annular slot formed in a cylindrical member 6 secured to the top of the outer tube 1. The balls are held in locking engagement with member 7 by a sleeve 8 located for axial movement over member 6 by co-operating sleeves 12 and 13 respectively integral with sleeve 8 and member 6. The member 6 carries also a flange 16 and the sleeve 12 a flange 14 between which is located a compression spring 15 enclosed in a telescopic sheet metal cover 17. The member 6 terminates in a connector 4 which carries the breech and firing mechanism (not shown) and member 7 is formed with ports 20 and member 6 with ports 21 so that when the gun is fired pressure gases pass through the ports 20 and 21 into the space surrounding sleeve 8. The annular base of this sleeve is of larger area than its top surface with the result that a differential load forces the sleeve upwardly against the action of spring 15 thereby freeing balls 5 and allowing the seat to separate from the aircraft. To enable the seat to be removed from the aircraft without firing of the gun, the balls 5 may be released by the manual operation of sleeve 8. The inner tube 2 is freely floating and is picked-up by tube 1 during ejection by means of blades (not shown). on the lower end of tube 1 which plough into a ring 37 of soft metal, thereby providing a shockabsorbing effect. Specifications 590,253 and 705,511 are referred to.

Title: Device for remote actuation of automatic firearms
IPC: F41A19/64
Filed: 1966-07-11
Abstract: 1,111,510. Remote control of firearms. HECKLER & KOCH G.m.b.H. 11 July, 1966 [15 July, 1965], No. 30995/66. Heading F3C. A remote control device for firearms comprises a housing, an actuating member, that is, a threaded spindle 3 and a nut 6, the threaded spindle being rotated by a motor 9. The nut 6 travels, from a rest position in two opposite directions to cock and fire the firearm. This is effected through an assembly which is engaged and moved by the nut, the assembly comprising a slider member or rod 21 having flanges 22, 23 at its ends and a spring-loaded sleeve 25 having a flange 26 mounted on the rod. To cock the firearm the nut 6 is moved to the right as shown in the Figure, a projection 28 on the nut engaging the flange 22 of the rod 21. In the final part of the movement of the assembly, the flange 26 of the sleeve abuts the end of a spring- loaded lever 45 and since the rod 21 continues its movement, the spring 27 is compressed. The flange 22 then engages a projection on the lever 45 to swing the lever out of the path of the flange 26 against its spring loading, the released flange 26 being urged by the spring 27 at high speed into engagement with a pin of the breech block to urge the breech block into its cocked position (Fig. 3, not shown). The speed of the cocking facilitates the ejection of a spent cartridge. To trigger the firearm the nut 6 is moved to the left, the projection 28 engages the flange 26 to move the rod 21 through the spring 27. The flange 23 engages a lever 61 of a lever assembly 61, 64, 65, 66, the lever 64 of which co-operates with the. trigger of the firearm (Fig. 2, not shown). A holder 35 for the firearm is mounted by means of springs 36 in a holder member 31, the member 31 being fixedly attached to the housing. The device is controlled by an electric circuit (Fig. 5, not shown) which includes a series of contacts, for example 71, 72, 73, built into the device. In a further embodiment (Figs. 6-9, not shown) an intermediate member is connected to a trigger actuating and breech cooking assembly by means of a cable. The intermediate member is driven in both directions of its operation by one or other of a pair of springs one situated at each side of a projection from the intermediate member and surrounding the ends of a sleeve. One spring and hence the sleeve, the other spring and the intermediate member are driven by a spring disc attached to the travelling nut.

Title: Follow-up indicator
IPC: G01J1/42
Filed: 1950-12-20
Abstract: 696,910. Photographic exposure meters. GOSSEN & CO., GES., P. Dec. 20, 1950 [Dec. 24, 1949], No. 31014/50. Class 98 (i). [Also in Groups XIX and XL (b)] A photographic exposure meter with a follow-up device comprises a photo-electric cell 5, Fig. 1, connected to a moving coil 3 between the poles of an electromagnet 2 so that the intensity of the light falling on the cell 5 determines the position of a pointer 4 carried by the coil 3. Stepped rows of " aperture values " are provided on a roller 10, Figs. 1, 5, and the appropriate row is brought into view in a slot 8, to be read against scales of " exposure times " and " frame advance speeds," by turning manually a knob 11 to rotate a roller 9 until one of a series of stepped scale markings 9a, Fig. 4, appearing through a slot 7 coincides with a point of the pointer 4, the rollers 9, 10 being interconnected by gears 20, 19. The relative position of the rollers 9, 10 may be adjusted initially in accordance with the sensitivity of the film by turning a disc 21 fixed to the spindle 22 of the roller 9 relative to the knob 11 which is connected by a sleeve to the gear 20 overcoming the friction of the coupling between the disc and knob which may be provided by a spring 23. A click-stop device may be used to hold the adjusted position. The scale markings 9a are shown as stepped but they could be of other form, e.g. a continuous curved line could be provided. The follow-up movement which results in computing " exposure times " and " frame advance speeds " could be used for control purposes and the movement could be obtained by a selfstarting device instead of manually. The roller 9 could be replaced by a transparent cylinder around the roller 10 bearing scale markings visible through the slot 8, the aperture values being read through the cylinder. In the modification of Fig. 3, a normal exposure meter is used, the scale 9 has uniform divisions and conversion of the non-uniform scale intervals of the scale 24 into uniform scale intervals is effected by curved lines. The roller 9 may be of polygonal cross-section or instead of rollers plates may be used being virtually developments of the cylinder. If it is desired to close an external electric circuit at certain points in the path of travel of the roller 9 a cam 12 may be provided to co-operate with contact points 16, one on a spring blade 17 and one on the back plate 15. The electric circuit could be used in range changing means.

Title: Improvements in or relating to the protective control of two or more inductively related electric circuits
IPC: E04C2/32
Filed: 1930-10-16
Abstract: 358,299. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Hull, J. I.; 1338, Dean Street, Schenectady, New York, U.S.A.) Oct. 16, 1930, No. 31055. Convention date, Oct. 18, 1929. [Class 38 (v).] Inductively-related (primary and secondary) windings are protected against overload in either circuit by current derived from one of the circuits proportional to the vectorial resultant of the load and magnetizing current in the other winding circuits. As shown, applied to the protection against overload of an induction motor which has its rotor or secondary connected to regulating apparatus consisting of a three-phase commutator machine driven 18 from the supply 10, 11, 12 by an auxiliary induction motor 19 in order to improve the power factor, a current-breaker 28 in the main and auxiliary circuit is tripped by coils 40, 41. The coil 41 is energized by a transformer 23 in one of the phases of the supply and operates to trip the circuitbreaker when the primary current is excessive. The coil 42 carries a resultant current made up of two parts (1) from the transformer 23 and (2) from a transformer 22, the primary of which is connected across two of the phases of the supply (or from two transformers each across two of the phases). The primary winding 24 has an impedance in series with it to adjust the phase displacement. The phase adjustments are made initially with the help of ammeters and an oscillograph so that the coil 40 is energized by a current at supply frequency derived from the primary circuit but proportional at all times to the current in the secondary. The motor is thus protected by two trip coils carrying currents which are a measure of those in the primary and secondary respectively and which, by reason of the regulating apparatus 18, 19, may not at all times be directly proportional to one another.
