Title: A bombing instrument for aircraft
IPC: F41G3/24
Filed: 1947-02-28
Abstract: 624,133. Bomb - sighting apparatus. SVENSKA AEROPLAN AKTIEBOLAGET, FAXEN, P. T., and WILKENSON, E. A. Feb. 28, 1947, No. 5815. [Class 92 (ii)] A bombing instrument is adapted to release bombs automatically on the correct trajectory towards a target during the pull-out after a glide or dive towards the target, and for this purpose comprises means for measuring the position and state of the aircraft in relation to the target, means for evaluating continuously during the pull-out a quantity #y which represents the difference between the direction of motion of the craft and the direction necessary to secure a hit, and a release impulse mechanism for releasing the bombs when #y becomes zero. In the construction shown the mechanism is brought into operation by a push-button at a point 3a just. before the pull-out and includes release mechanism 6 which functions when the following equation is satisfied : # - α=#, # being the angle through which a fixed optical axis 4b on the craft turns during the pull-out, a being the angle between the optical axis and the tangent v to the flight path, and # being the requisite angle of divergence. As shown diagrammatically in Fig. 4, such data is fed to the mechanism 6, being combined together by differential gear, the data # serving to rock a pivoted arm carrying an electric contact, and data a and e serving to rock a second arm also fitted with a contact which co-operates with the first to release the bombs when the formula is satisfied. The value # is obtained from a gyroscope 7 which is released for operation when the push-button is pressed. The angle x is determined by an equation depending on the specific wing loading G/F of the aircraft, its acceleration n in a direction perpendicular to the plane containing the wings and fuselage, the dynamic air pressure q, and certain constants. These are obtained as shown by a manual control 9, accelerometer 10, and manometer 11, and are combined in accordance with the formula by a calculating device 8 which feeds a to the mechanism 6. The requisite angle e is given as a function of the angle of dive #, height of release h, velocity v, and wind speed u, and the Specification describes how it is possible to obtain data corresponding to that angle in a calculating mechanism from apparatus which includes a manometer 17 for obtaining static air pressure p, a control 18 in which is set air pressure p, at ground level, a manometer 11 for obtaining dynamic air pressure, a gyroscope 14 for obtaining #, a control 13 for setting in u, and calculating mechanisms 15, 16. Such devices are interconnected as shown in Fig. 4. In a modification the positional data set in to the mechanisms correspond to the various angles to the horizontal.

Title: Improvements in or relating to carburettors
IPC: F02M3/08
Filed: 1930-02-21
Abstract: 349,456. Spray carburetters. DURAND, R., 1, Rue du General Delanne, Neuilly-sur-Seine, France. Feb. 21, 1930, No. 5877. [Class i (iii).] The carburetter, which is designed to eliminate the " gap " which usuallv occurs in the feed of mixture during the change from the slow-speed nozzle to the main nozzle, comprises a constant level chamber 3, a mixing chamber M containing a main nozzle 5, and a slow-running nozzle 1 connected by a duct m to the engine side of a throttle valve 10 in its closed position. The nozzle 5 is connected to the chamber 3 by two conduits 6, 2, a well 8 open to atmosphere branching from conduit 6. Between the well 8 and chamber 3 is a calibrated orifice 7, and another calibrated orifice 4 is placed between chamber 3 and the junction of conduit 2 with the slow-running nozzle 1. Above the nozzle 1 is an air inlet 9. The Specification describes, at length, what occurs at different throttle openings, and how the various conduits and calibrated orifices combine to produce the desired results.. In a modification, Fig. 2, additional parts enable the carburetter to be used with motors which require a longer period of overlap between slow-running and main supply. The additions comprise a calibrated orifice 11 between nozzles 1 and 5 in conduit 2; an air inlet tube 12 with calibrated orifice 13 and communicating with conduit 2 on the main nozzle side of orifice 11 ; a cylindrical valve casing A provided with a valve 14 and having an air inlet passage 15; an air-inlet conduit 9 from valve casing A to the down-stream side of nozzle 1, and a conduit 16 with calibrated orifice 17 between the valve casing and float-chamber 3. When valve 14 is in the position shown in Fig. 3, the operation is the same as that of the carburetter described above, except for the effect of calibrated orifice 11. The Specification describes also the action of the carburetter when the valve 14 occupies the positions shown in Figs. 2 and 4 respectively.

Title: Improvements in the production of thermoplastic films
Inventor: AVERNS JOHN ANTHONY
IPC: B29C48/90
Filed: 1956-02-27
Abstract: <PICT:0798238/IV (a)/1> Molten thermoplastic material is extruded through an annular die, the resulting tubular film is inflated in known manner and the inflated tube is then passed through a hollow, rigid, perforated cylinder which is flattened to a "fishtail" at the other end, so that the tube is collapsed in the cylinder and leaves in the form of a flat ribbon.  As shown, molten material is extruded through an annular die 8 having an orifice 9.  The inflated film 11 passes into the hollow cylinder 12, which may be made of bronze gauze, slowly cools therein, and escapes through the terminal slot as a flat ribbon, carried away by rollers 18, 19.  The gauze cylinder 12 is held in position by clamps 15, 16.  Flattened tubular film produced in this way is said to show little or no tendency to crinkle in passing along the rollers to the winding mechanism.

Title: Improvements in or relating to stud welding apparatus
IPC: B23K9/20
Filed: 1968-02-07
Abstract: 1,223,753. Welding by pressure. ROBERT WATSON & CO. (CONSTRUCTIONAL ENGS.) Ltd., and E. CHIFFEY. 24 Feb., 1969 [7 Feb., 1968], No. 5994/68. Heading B3R. An apparatus for welding studs to a beam B comprises a carriage, means for moving the carriage along the beam, a plurality of welding guns 16 mounted on the carriage and means for moving each gun, by a movement including tilting, from a welding position to a stud accepting position in which electric supply to the gun is cut. The carriage consists of a frame 1 having four adjustable sets 2 of three wheels, each set including a vertical wheel for supporting the carriage on the top face of a beam and two smaller horizontal wheels to contact the side of the beam. The wheels are adjustable for track width and this is effected on a setting table and for clearance between the frame 1 and the beam. Each of the welding guns 16 mounted on the frame 1 has a body 17, Fig. 3, carrying a spring collet 19 for a stud 5 and a rack 20 is attached to the body for meshing with a pinion 21 carried by a trunnion 22 on which the gun is slidable, the trunnion 22 being mounted on an axle 23 on the frame. The pinions 21 also mesh with gear quadrants 24 movable by cams 25 on a shaft 26 driven from a motor 28 on the carriage. An electrical contact 29 is carried on each body 17 to supply current from a bus-bar 21 to the collet 19. With a gun in its welding position (see Fig. 3) operation of the appropriate cam 25 causes the quadrant 24 to rotate the pinion 21 and since the gun cannot rotate about axle 25 by virtue of engagement of contact 29 with bar 31 and of collet 19 with stud 5 the gun is lifted vertically until a stop pin 3d engages the trunnion 22 and then rotates about axle 23, the contact 29 having disengaged from the bar 21 and the collet from the stud. A fresh stud and ferrule can be inserted by an operator into the gun. A claw 32 reciprocated by a connecting- rod on a crank rides over a welded stud in its forward movement and then drops over the stud so that on backward movement of the claw the carriage is dragged forward into a new welding position. In operation the guns are in sequence raised to the tilted position where studs and ferrules are inserted, the carriage is advanced by the claw into the new position and the guns are lowered in turn to the studs. Only one gun contacts the bus-bar at a time, each gun being raised immediately after completing its weld. A similar apparatus having different beam engaging rollers is described.

Title: Trunk piston
IPC: F16J1/06
Filed: 1929-02-23
Abstract: 325,122. Flammang, J., and Bowser, P. L. Feb. 23, 1929. Pistons, balancing laterally; packing. - In a trunk piston of aluminium or the like a split ring 8 in the head is maintained at the same diameter as the cylinder by means of a strut 9, having the same coefficient of expansion as the cylinder or of relatively inexpansible steel. The strut passes loosely through slots in the ring groove and may be secured by a stud to a pillar 11, or may be formed adjustable by the cam-end 12 of a spindle 13, which is turned by means of a head 14, and is secured by a nut 15. A similar ring and strut may be fitted at the lower end of the skirt, the strut in this case being slotted, to permit oscillation of the connecting-rod, and secured by a stud passing through the ring groove. The skirt may be formed with a circumferential slot 22 and an axial slot 21, and slots 23 may be made from the edge of the skirt. Alternatively, the diameter of the skirt may be relieved at the points between the thrust and gudgeon-pin diameters, tapering to circular form near the head, by inserting a ribbed and tapering mandrel and machining the skirt circular while distorted.

Title: Improvements in or relating to duplicating machines
IPC: B41L11/00
Filed: 1958-02-26
Abstract: 822,874. Rotary duplicators. RITZERFELD, W., and RITZERFELD, G. Feb. 26, 1958 [March 22, 1957], No. 6222/58. Class 100(2) In a rotary duplicator for printing lines or sections from a master sheet on to copy sheets the counter pressure roller is moved towards and away from the printing drum at the appropriate times under the control of an electromagnet operable by switching means actuatable by control means on a member rotatable in timed relationship with the drum, manual setting-means being arranged to predetermine which control means actuate the switching means. As shown, a master sheet 2 on a driven drum 1 has lines Zl to Z16 thereon, and a counter pressure roller 6 in pivoted arms 7 is adapted to be moved into contact with the sheet 2 to print a particular line, such as Z5, when a setting-key T5 is depressed. The key T5 makes contact with a stud K5 on a rotating cylinder 19 to complete an electric circuit from a rectifier 27 to two electromagnets 13 which then move rods 12 to the left, these rods acting on two toggle joints 9, 10 to move the roller 6 towards the drum 1, against the action of springs 29. The cylinder 19, which is driven by the drum 1 through bevel gearing, is made of insulating material and carries contact studs K1 to K16 arranged helically on the surface, these studs being connected together and to an end member which is always engaged by a contact 28 in the rectifier circuit. Setting-keys T1 to T16 on a key-board 20 can be depressed to engage the cylinder 19, and make contact with the corresponding studs K1 to K16, so that any particular line Z1 to Z16 can be printed. In modifications, a single helical contact strip can be used instead of separate studs K1 to K16, the drum 1 may drive the cylinder 19 directly, the cylinder 19 may be disposed in alignment with the drum 1 or at any angle to the axis thereof, and the electromagnets 13 may urge the roller 6 away from the drum 1 against the action of springs. In a second machine (Figs. 2 and 3, not shown), the contact studs K1 to K5 of Fig. 1 are replaced by conducting recesses in the surface of the cylinder 19 each of which can be engaged by a roller on spring-urged lever, when the corresponding setting-key has been depressed, to open circuit and cause the electromagnets 13 to be de-energized. In a third machine (Figs. 4 and 5, not shown), the contact studs K1 to K5 of Fig. 1 are replaced by cam projections each adapted normally to rock a lever idly as the cylinder rotates; when, however, a setting-key is depressed, the corresponding rocking lever lifts a common, transverse bar to close the circuit which includes the electromagnets 13.

Title: Improvements in or relating to wireless receiving circuits
IPC: H03D11/02
Filed: 1924-03-11
Abstract: 238,261. Robinson, J., and Kinman, T. H. March 11, 1924. Thermionic amplifiers and detectors.-Relates to oscillating-valve receivers in which the grid condenser or leak resistance is so adjusted that the frequency of an exciting, pulsating or " squegger " effect is varied by the incoming signals. To increase the amplification, the frequency of the local oscillation is made equal to the signal frequency. In Fig. 2, the ordinary leak resistance of the oscillating receiver 3 is replaced by a two- or three-electrode valve 9, which shunts the grid condenser 4, and is in series with the aerial system 1, 2 across the grid and filament of the valve 3. The aerial circuit may be inserted across the grid and filament of the valve 9, or as shown in Fig. 4, the unearthed end of the aerial 2 may be connected to the grid only of the auxiliary valve 10. The pulsating or quenching frequency is made supersonic for telephony. For heat reception the circuit 13, 14, Fig. 5 is tuned to the supersonic frequency, and coupled to a local oscillator 15. Fig. 6 shows a circuit for obtaining both high and low frequency amplification. The valve 16, acting as a variable grid lead or pulsator across the grid condenser 4, serves also to amplify the low-frequency currents fed from the plate of the main valve 3 across the transformers 17, 18. Specifications 153,690 and 159,377 are referred to.

Abstract: 1,011,618. Endless belt conveyers. JOHNSMANVILLE. Feb. 14, 1964 [Feb. 15, 1963; Nov. 26, 1963], No. 6344/64. Heading B8A. A conveying apparatus for removing a web of extrudate 12 (Fig. 1), from the die F of an extruder comprises an endless belt 2 passing over a fixed idler roller 10<SP>1</SP>, a tensioning idler roller 10 and free-rotating rollers 3, 3<SP>1</SP>, 3a, 3a<SP>1</SP> carried by pairs of endless chains 40, 40<SP>1</SP>, spaced by bushes 5, 51 with rollers 70, 70<SP>1</SP> mounted thereon. The rollers 3, 3<SP>1</SP> in the upper run are supported by the rollers 70, 701 running on a track 13. The lower rollers 70, 70<SP>1</SP> run on a track 13<SP>1</SP>. The chains 40, 401 are driven by a motor 60 in the direction of arrow G 3  at a speed V 3 . V 3  is about 10% higher than the extrusion speed V 1 . When belt 2 is not loaded it rests on rollers 3, 3<SP>1</SP> under its own weight. If the bearings of rollers 3, 3<SP>1</SP> develop a normal friction resistance and if the belt 2 is only slightly tensioned, then belt 2 is driven in the direction of arrow F 2  at a speed V 2  which may be lower than or equal to V 3 . If the belt 2 is loaded with extrudate 12 at a speed of V 1  then, if the friction between the belt 2 and the extrudate 12 is sufficient there will be no slippage between the belt and the extrudate so that the belt tends to move at the speed V 1  and will automatically match itself to any change in that speed. Figs. 3a, 3c show two stages in cutting extrudate 12 into lengths A, B and separating them. Conveyers 100, 300, 400 are all of the type shown in Fig. 1, conveyers 200, 500 are roller conveyers. Fig. 3a shows a length A of extrudate 12 about to be cut by a cutter K. After cutting, conveyers 300, 400 are speeded up to separate A from the following, as yet uncut, length B. Fig. 3c shows conveyer 400 still at a fast speed while conveyer 300 has been reduced in speed to its original value to receive length B. When length A has cleared conveyer 400 the latter also reverts to its original speed.
