Title: Improvements relating to automatically operated change speed gears
IPC: F16H61/02
Filed: 1950-01-05
Abstract: 676,549. Variable-speed gearing. DAIMLERBENZ AKT.-GES. Jan. 5, 1950 [Jan. 5, 1949], No. 334/50. Class 80 (ii). In change-speed gearing wherein an upward change is effected or pre-selected automatically at an adjustably-predetermined vehicle speed and change-down occurs at a lower speed, the difference between the two speeds varies in accordance with the adjustment of the said predetermined speed. Change-down can also be effected at will by kick-down of the accelerator. In the over-drive gear shown in Fig. 1, speed changes, are controlled by a double clutch 8 actuated through a spring toggle 10, 11, 12 by a piston 14 loaded by a spring 16 which tends to engage direct speed. A vehicle-driven pump 17 delivers oil to the cylinder 15 through a pipe 19 at a pressure depending both on the vehicle speed and on the adjustment by a lever 28 of a throttling valve 23 arranged in an exhaust pipe 20 branching from pipe 19. The vehicle speed at which the piston 14 moves to the right against the action of springs 12, 16, to engage overdrive, thus depends on the adjustment of valve 23. When over-drive has been engaged, the toggle spring 12 opposes spring 16, so that overdrive remains engaged until a speed lower than that at which it engaged is reached, this difference of speed being approximately one-quarter of the speed at which over-drive engages. A by-pass 30 round the valve 23 has a valve 31 which is normally closed by a spring 33 but which is opened on kick-down of the accelerator 34 beyond fully-open position so as to effect change-down at any speed. In the form shown in Fig. 2, supply of oil from pump 17 alternatively to opposite sides of a piston 45 actuating the gear is controlled by a valve 35 rigid with a piston 14' subjected on its left side to the pump pressure, which latter again depends both on vehicle speed and on the adjustment by a lever 28<SP>1</SP> of a throttling valve 23<SP>1</SP>. Movement of valve 35 to the right is opposed by springs 16<SP>1</SP>, 56 and movement in either direction is additionally opposed by a detent 53 which co-operates with notches in the valve and the spring 52 of which abuts against a lever 50 linked to the lever 28' so that the loading of the detent depends on the adjustment of the valve 23<SP>1</SP>. The detent ensures that the down-change speed is less than the upchange speed. The spring 56 abuts against a piston 57 which is moved by kick-down of the accelerator 34 beyond fully-open position so as to cause valve 35 to move to the left to produce down-change.

Abstract: 417,635. Making electric conductors. CROAD, A. K., 70, Chancery Lane, London.- (General Cable Corporation; 420, Lexington Avenue, New York, U.S.A.) Jan. 4, 1934, No. 381. [Classes 83 (ii) and 83 (iv).] Rolling.-A stranded electric conductor having a core 12 and a number of layers of helically-arranged strands around the core is manufactured by compress ing each layer of strands, which may be originally circular in section, so that a substantially smooth outer surface is presented before the next layer is applied. Fig. 3 shows such a conductor that is sector-shaped in section and adapted to be combined with two other similar conductors and suitable wrappings to form a three-conductor cable. Fig. 1 shows its method of manufacture, the core 12 being unwound from a reel 11, and the strands of the successive layers 21, 27, 34 being unwound from reels 14, 24, 31 which are mounted on frames adapted to be rotated, preferably all in the same direction by pinions 16, 26, 33 on a motor driven shaft 17 that also drives the capstan 20 that receives the finished conductor. The cable after receiving each layer of strands 21, 27, 34 passes through suitably shaped rollers 22, 28, 29, 35, 36 to be compressed. The rollers 22, 28, 35 serve to compress it in a vertical direction. Each set of rollers 29 or 36 while preventing it from expanding vertically, compresses it horizontally, three rollers co-operating for this purpose.

Title: Improvements in and relating to gas turbine cycles with interstage reheating
IPC: F02C3/32
Filed: 1933-01-06
Abstract: 412,970. Gas turbine plant. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and SAMUELSON, F., 44, Hillmorton Road, Rugby. Jan. 6, 1933, No. 547. [Class 110 (iii).] In a gas turbine plant comprising a multi-stage turbine or two or more turbines, the working gases are reheated between stages by mixing them with gases drawn direct from the combustion chamber. In Fig. 1 a high pressure turbine 13 supplied by a combustion chamber 7 drives a generator 14 and its exciter 15, and a low pressure turbine 17 drives a compressor 1 for the charge air. This air, which may be preheated by the exhaust gases, is passed in part by a damper-controlled port 4 to the combustion chamber 7 in which fuel introduced by a pipe 3 is burnt, and in part by a dampercontrolled port 9 to a chamber 11 surrounding the combustion-chamber at the end 8 of which it mixes with part of the combustion-products and passes by a conduit 12 to the turbine 13. In their passage through the conduit 16 between the turbines 13, 17, the working gases are reheated by combustion products introduced from the chamber 7 by a pipe 18. These products may be fed in by an injector in order to increase the pressure in the pipe, and the supply may be controlled by a damper 19, or by a needle valve, which may be actuated automatically by a thermostat. In a modification, four turbines are arranged in series, two of them driving the power generator, and the other two driving series charge compressors at different speeds. Reheaters are arranged between the turbines as described above. The last turbine discharges into a chimney in order to reduce the back pressure. Fig. 5 shows an arrangement in which the turbine stages are supplied by conduits 31, 35, 39, 43 and in which the injectors 34, 38, 42 for the supply of interstage reheating gases are controlled by interconnected valves 44, 45, 46. The valveoperating cam-shaft 50 is actuated by a thermostat in the gas system, and a manual adjustment 54 is provided for each valve. More than one thermostat may be provided. Interstage combustion chambers for reheating may also be provided.

Title: Diffuser for warm air heating systems
IPC: F24F11/02
Filed: 1962-01-08
Abstract: 931,578. Ventilators. L. G. DAYUS. Jan. 8, 1962 [Aug. 11, 1961], No. 618/62. Class 137. [Also in Group XXIX] In an air outlet diffuser for an air-heating system having a substantially rectangular frame formed by side walls, a valve opening and a grille opening are spaced apart by the depth of the side walls, and the valve opening is closed by at least one pivotally-mounted damper plate which is actuated by slidably engaging fingers of an actuating arm pivoted in a side wall. As shown, Fig. 1, the four side walls are joined by inserting tabs 16 on sides 12, 13, into slit portions 17 in sides 14, 15. A plate 18 having downwardly-projecting flanges 19, 20 which are attached to the walls 14, 15, e.g. by spotwelding, forms a top flange 23 to the frame and also includes integral diffuser blades 21 to form the grille opening. The blades at the centre of the opening are substantially vertical, those toward the ends being progressively more oblique. Two similar damper plates 25, 26 are pivoted about parallel longitudinal axes by extensions 27 bearing in holes 28 in walls 14, 15. In the closed position these dampers overlap at the inner edges and bear on inward flanges on the walls 12, 13 at the outer edges. An actuating arm 39, Fig. 3, pivoted on wall 14 has an end 41, Fig. 4, terminating in a pair of fingers 42 which slidably engage the damper 26. A secondary actuating arm 43 also pivoted on wall 14 engages damper 25 in a similar manner and also has a projection 47 engaging with a slot 48 in the primary arm so that the two arms rotate in opposite senses. The upward movement of the outer edge of damper 26 is limited by a tab 50 on an adjustable stop arm 49 which is pivoted on the same pin 40 as the primary actuating arm 39 and has a depressed portion 51 which with ridges 52 on the actuating arm limits relative movement of the arms 39 and 49. A slot 53 on the stop arm allows engagement of an adjusting tool.

Title: Apparatus for the photo-electric sensing of symbols and figures
IPC: G06V30/224
Filed: 1956-01-09
Abstract: 794,139. Statistical apparatus. LORENZEN, J. F. Jan. 9, 1956, No. 666/56. Class 106 (1). [Also in Group XL (b)] An apparatus for the photo-electric sensing of symbols and figures is characterized by a mosaic screen 5 interposed in the path of light from at least one magnifying lens system 3, 4, to several reducing lenses 6, corresponding in number with the perforations in the screen and refracting the light more particularly through adjoining reflecting funnels 8 on to a corresponding number of selenium cells 9, each cell being electrically connected by a number of stranded wires with an associated relay in such manner that the configuration of a symbol is sensed and transmitted in mosaic for mechanical reproduction on a record or for the appropriate actuation of the key of an office machine. Each cell carries a very weak current which is increased when light falls on to it and this increased current is passed to an associated distributer disc such as 10. Each distributer has attached to it the same number of wires as there are mechanical relays 12 and each wire leads to a field of a relay. The leads carrying increased currents cause the appropriate relay to be energized. Preferably electronic relays may be used. The corresponding effect may be achieved by the depression of a machine or computer key 15 by means of an electromagnet 14 energized via a valve 13. Once the objective has moved into position over the relative mark, shutter 18 opens automatically for a short exposure.

Patent GB-283928-A (GB)
Title: Improvements in small-arms
IPC: F41A3/18
Filed: 1928-01-11
Abstract: 283,928. Verney-Carron et Cie. Jan. 20, 1927, [Convention date]. Breech actions, sliding breech-block; barrels; stocks.-A smallarm of single-barrelled or doublebarrelled type is made with a stationary topplate 11, F´g. 1, over which slides a breech-block 2'1 provided with a number of rotatable heads 24 for locking the breech-block in the closed position, these heads being incapable of longitudinal motion relatively to the breech-block. The heads 24 have shanks 23 formed with curved grooves 29 engaged by studs 33, Fig. 4, on a longitudinally sliding member 25, which is operated through a link 36 by a lever 27 pivoted to the breech-block at 39, a spring 35 being interposed between the back of the member 25 and an abutment on the breech-block. A roller 41 at the end of a short arm 40 rigid with the lever 27 bears on the plate 11 and holds the lever in the open position until the breech-block is moved forward to the closed position. The roller 41 then comes over a slot in the plate 11, and allows the lever 27 to be swung down. This rotates the heads 24 and makes teeth 30 thereon interlock with corresponding teeth in the socket-piece 3, to which the barrels are secured. The reverse movement of the lever 27 unlocks the breech and allows the breech-block to be pulled back. An extractor 8 is simultaneously retracted by a lug 42 on the breechblock, which lug also limits the movement of the breech-block by engagement with a fixed stop. The retraction of the breech-block also swings the firing hammers 16 back to cock in engagement with triggers 44, 45 at the same time compressing the springs 52. The hammers may be locked or unlocked by a cam 54 adjusted by a small external lever and held in place by a spring 55. If the hammers are unlocked, a pull on a trigger releases the corresponding hammer, which swings and strikes a firing pin 32, Fig. 2, slidably mounted in the rotatable head 24. A slot 31 in the rear end of the head 24 allows the hammer to reach the firing pin only if the head has been fully rotated to complete the locking of the breech-block. The stud 33 which operates the rotatable head also serves to limit the longitudinal movement of the firing pin. The socket-piece 3 to which the barrels are screwed has a boss 9, which fits in a recess 14 in the plate 11 and is secured to the front part of the stock by a bolt 12 provided with a handle 13. The two barrels 1, 2, Fig. 7, are connected together throughout their whole length by a bridge-piece 4. The triggers and firing hammers are carried bv the cheeks of a bottom plate 19, which is interlocked at its forward end with a lug 18 depending from the top plate 11, and is secured at its rear end to the rear part of the stock together with the top plate 11 by a bolt 20. The trigger-guard 43 is attached to the bottom plate 19.
