Filed: 1944-06-23
Abstract: 580,890. Rotary pumps. HILL, H. R., and PORTLOOK, H. June 23, 1944, Nos. 11940/44 11941/44 and 7825/45. [Class 110 (ii)] [Also in Group XXIX] A fluid power transmission having a pump 5 and a motor 6 of the outwardly-sliding vane type, with inner and outer working chambers 28, 27 respectively, is provided with rotary casing walls 9, 12, 18 and 9a, 12a, 18a. To vary the capacities of the working chambers, eccentrics 41, 42 are rotated in opposite directions by a bevel wheel 46 which meshes with gears 49, 45, integral with sleeves fixed to the eccentrics. A central fixed partition 4 has recesses for projections 22 on the rotors, containing passages 23, 24, connecting with inlet and discharge ports 29, 300 respectively. Rotor segments 11 are secured to rotor end plates 9, 12, and between each pair of segments two-part vanes 15, 16, are located. These bear through packing pieces 51 , on rotating rings 17, 19. Other packing blocks 19. are pressed outwards by rubber rings 36. and have stops to prevent rotation. Fluid pressure is exerted on the backs of spring-pressed packing blocks 32, 320, in the partitions 4, by way of ducts 59, 590. Fluid discharged from the pump 5 passes to the motor inlet 300a by way of a passage 640, or an inlet 30a by way of a passage 64. This secures balance of end thrust between driving and driven shafts 1, 2. Rotation of a control shaft 47 causes eccentrics 41, 42, to rotate in opposite directions to impart a displacement to the inner and outer walls 17, 18. The vanes maintain the radial spacing of the walls 17, 18. The outer wall is guided by parallel slides 55 carrying bearings 56. Resilient or spring members and fluid pressure may be used to press parts 15, 16 of the vanes apart. The shafts 1, 2 may be driven in reverse directions, or at varying speeds. The first Provisional Specification states that other than outwardly sliding vanes may be used.

Abstract: 474,241. Propelling and controlling aircraft. JONG, A. DE, and VOLPERT, L. April 27, 1936, No. 11976. [Class 4] In an aeroplane having a thick wing of deep section and rounded leading edge mounted on the fuselage so that leading edge and upper surface are continuous across the span whilst the under surface is interrupted by the fuselage, a forwardly directed air inlet opening is formed in the fuselage nose and has a cross-sectional area approaching the maximum cross-sectional area of the fuselage, the opening being connected to the suction side of an air pump, the discharge side of which is in communication with one or more transversely extending slots formed in and confined to that part of the wing leading edge which is above the fuselage and, optionally, also extends for a short distance on each side thereof, the arrangement being such that all or substantially all of the air discharged by the pump is discharged through the slot or slots substantially upwardly and tangentially to the leading edge of the wing. In one form, Fig. 2, a fan c draws air through an opening d in the nose of fuselage band discharges it at e tangentially to the surface of the leading edge of wing a. Discharge openings p in the fuselage walls may be connected to the discharge side of the fan during starting. In a modification, Fig. 2, multiple discharge openings e are defined by elements f rotatable about transverse axes g which are automatically adjustable in accordance with pressures of the relative wind and of the outflowing air. In a further modification, Fig. 3, a centrifugal fan c is fitted in the wing nose, and discharges air through opening e. The wing may be provided with slots h as shown in Figs. 4 and 5. These are stated to increase the propulsion due to the suction effect and run longitudinally from the section of greatest wing depth to the trailing edge, are directed obliquely toward the fuselage, and increase in section from extrados to intrados. A fuselage may be employed of which the cross-section is reduced rearwardly to a minimum at the trailing edge of the wing at which point the fuselage is only of such cross-section as is necessary for the support of an empennage. Valve-controlled discharge openings such as r, Fig. 4, may be provided for lateral control. The aerofoil section in the region of the discharge opening e may have a steeper nose than the remainder of the wing as shown in Fig. 7, the leading edge n in this part being inset with relation to the leading edge m of the remainder.

Title: Spark-discharge devices for igniting explosives
IPC: F42B3/103
Filed: 1957-04-16
Abstract: 816,530. Electric igniters for explosives. ROCHAT, J. April 16, 1957 [April 30, 1956], No. 12440/57. Class 9(1) An igniter similar to that described in Specification 735,609 comprises a metal sleeve 1 connected to the positive pole of a voltage source T and having a stepped bore forming a shoulder 1a on which rests a cylinder 2 made of an aluminium alloy. A metal rod 3 is secured in a blind hole 2a in the cylinder 2 and through a contact switch D is connected to the source T. If the igniter is in a projectile, the switch D may be arranged to close on impact. Before inserting the cylinder 2 in the sleeve 1 an oxide layer 2b is formed on the whole of its free surface by anodization using the rod 3 as a pole. The oxide layer is then punctured on the flat surface opposite the rod 3 and one or more layers 5 of a colloidal metal, e.g. silver, deposited on that surface and in the puncture 4 as in the earlier Specification. After heating to a temperature between 600‹ and 700‹C. to bake the layer 5, the cylinder is placed in the sleeve 1.
Patent GB-494839-A (GB)
Title: Improvements in and relating to cathode ray apparatus
IPC: H01J29/66
Filed: 1937-05-01
Abstract: 494,839. Cathode-ray tubes. BRITISH THOMSON - HOUSTON CO., Ltd., and MYNALL, D. J. May 1, 1937, No. 12476. [Class 39 (i)] The invention relates to cathode-ray tubes, with magnetic focusing, particularly for television reception. It is explained in the Specification that when the anodecathode circuit of the tube and the magnetic lens are supplied from a common source, the focus varies with the mains voltage, for the reason that the ideal curve connecting I (the current in the focusing coil) and V (the anode-cathode voltage) has the form I = aV¢ whereas the practical curve is of the form I=bV, b being a constant and a a constant so long as there is no magnetic saturation. According to the invention, the focusing means is so arranged that the curve showing the relation which must hold between I and V and the curve which is obtained under working conditions are so closely aligned over a predetermined range of valves of V that the ray is maintained substantially , in focus over that range. In one arrangement alignment of the curves is obtained by designing the lens to operate in a saturated condition, and in Fig. 5, the lens comprises a magnetic body having an annular air gap C and carrying a winding A. The magnetic circuit is restricted at D and an adjustable magnetic shunt E may be provided to vary the value of flux at which saturation is obtained. In a modification, the restriction is at the side and is shunted by an adjustable plate screwed into the body. These two forms may be used in combination. In a further modification, the required effect is obtained by the use of an auxiliary magnetic field independent of V, and according to Fig. 7, a normal lens J is combined with a permanent magnet K in such a way that the part M carries the difference between the two magnetic fluxes. The field of the permanent magnet may be varied by means of an adjustable element N. The constant field may be obtained by the use of a separate permanent magnet, by means of an auxiliary winding supplied with constant current, or by means of a separate lens supplied with constant current. Adjustments may be dispensed with if the working conditions are not liable to extensive change.

Abstract: 584,320. Chucks. STEINLE, L. C., and HANWELL, C. H. June 30, 1944, No. 12484. [Class 83 (iii)] Fluid-operated chucks have a cylinder and piston unit for each jaw housed within the chuck body. The jaws are adjustably mounted by screws and serrated surfaces b on carriers a that may have guide extensions 13, 14, 15 extending beyond the axis as described in Specification 584,321. The jaws are operated by cams on a ring g, acting through floating abutments j<1> on the carriers. The ring runs on needle rollers h and is actuated by toroidal pistons d engaging abutments carried by the ring, one for each jaw. Springs i return the ring. Oil is supplied to each cylinder from a reservoir w, closed by an elastic annulus 16 so that the reservoir remains full and air is excluded, by a pump unit x reciprocated by a cam 2 on a short spindle 3 operated by a key 4. The pumps draw from the reservoir by pipes 7 and non- return valves r and deliver to the cylinders through ports o and non-return valves w. The ports o are all interconnected so that all the pistons are operated by the actuation of any one pump. Release valves 9 are fitted, actuation of any of which by the taper end 11 of the key releases the pressure in all the cylinders.
Patent GB-660263-A (GB)
Title: Improvements in or relating to power mechanism for typewriters and like machines
IPC: B41J7/94
Filed: 1948-05-06
Abstract: 660,263. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 6, 1948 [June 5, 1947], No. 12492/48. Class 100 (iv). A power type action for a typewriter comprises a rotatable power roller 30 which is engaged by a cam 28 to actuate an associated type-bar 16, the blow imparted thereby being adjusted by means effecting disengagement of the cam 28 from the roller 30 at adjustable and differing points in the rotation of the cam by the roller 30. A key 10a, mounted on a lever 10, and pivoting about a pin 11 has a depending lug 10b which upon operation of the key, engages a release member 31 pivotally attached by a pin-and-slot connection 31b to a sub-lever 19. Release member 31 coacts with an extension 28c of the cam 28 which is pivoted at 19b to sublever 19 and moves it into contact with the power roller 30 which therefore continues to rotate the cam 28. The edge 28b of the cam is eccentric with the cam point 19b which is thus moved in an arcuate path to move the sublever 19 clockwise about a fulcrum 26a to effect, via link 20, movement of the typebar 16. The force applied to each type-bar 16 is individually adjustable by varying the point at which the cams 28 become disengaged from the power roller 30. This is effected by the contact of the extension 28c of the cam with a finger 34b of a combstrip 34 which is raised or lowered on a framework 33 by a screw adjustment 35. The clearance between the cam 28 and the power roller 30 is adjustable by longitudinal movement of stops 26 in slots in the frame 33, the stops being frictionally clamped in position by a resilient stop 37, within a channel-shaped bar 36. A spring 29 connecting the parts 19, 28 and the resiliency of the usual rubber covering of power roller 30 assist to produce a snappy disengagement with little slippage when the cam is forced off the power roller.
