Title: Improvements in or relating to machines for assembling and charging machine-gun cartridge belts of the disintegrating type
IPC: F42B39/10
Filed: 1939-11-27
Abstract: 539,184. Cartridge belt filling machines CHALMERS, J. W., DEARSLEY, G., HARRIS, R. W., and MOLINS MACHINE CO., Ltd. Nov. 27, 1939, Nos. 30822/39, 8782/40 and 8783/40. [Class 92 (ii)] [Also in Group XXX] A machine for charging clips with cartridges to form belts for feeding automatic guns comprises, in combination, conveyer mechanism to feed forwardly a succession of unassembled clips and cartridges arranged transversely to the conveyer in position for assembly, and means for assembling the cartridges and clips by moving the cartridges into gripping engagement with their respective clips whilst these items are being fed forwardly by the conveyer. In the machine shown in plan in Figs. 5A, 5B and in part elevation in Fig. 4B, a bed 10 supports a chain conveyer 11 the sprockets 25 of which are mounted on spindles 26, 27 and the links of which form a straight upper run with transverse flutes 21 to receive the separated but aligned cartridges x and clips y as shown to the right of Fig. 5A. The clips are of the kind which are hinged together by the inserted cartridges to form a disintegrating chain belt. The cartridges are supplied from hoppers 12 as described in Specification 541,955, [Group II], to shoots 48 leading to fluted drums 13 which feed the conveyer at four stations, the number of flutes in each drum being preferably suited to the desired disposition of cartridges of different kinds in the assembled belt as described in Specification 539,221, [Group XXX]. The clips are arranged in correct orientation in containers which are fed at 15 to means as described in Specification 541,954, [Group XXX], for stripping and ejecting the containers so that the clips can fall by gravity down an incline 14 on to the conveyer. The cartridges are moved progressively into the clips by plungers 54 on an inclined endless chain 51 which passes over a sprocket 52 and a shaped guide 53. The plungers move in such a way that they exert components of movement on the cartridges both along the cartridge and in the direction of movement of the conveyer. A sprocket wheel 57 ensures correct positioning of the cartridges whilst the pressure is being applied, the links being supported by abutments 23. The leading end of the charged belt passes under a pressure plate 58 and over a stripping plate 59 to a guide 60 perforated at 61 for the passage of loose links when starting up the machine. The machine is power driven by a pulley 100 on a main shaft 101 having worm gears 104 for driving the drums 13, a worm gear 108 for driving the vertical spindle 106 of the sprocket 52 for the chain 51, and a worm 109 which drives the sprocket shaft 26 of the conveyer. The shaft 26 also drives a counter shaft 113 geared to the sprocket 57 and has cams 45 for driving the hopper feed members 32, and a bevel gear 123 actuating the shaft 82 of the charger-clip feed. Specification 325,972, [Class 92 (ii)], also is referred to.

Abstract: 956,558. Pharmaceutical granules. GLAXO GROUP Ltd. Sept. 2, 1960 [Sept. 10, 1959], No. 30964/59. Heading A5B. [Also in Divisions A2, B5 and F4] Powdery materials such as pharmaceutical products which may contain a binding agent, e.g. magnesium stearate, are granulated or agglomerated by first forming them into individual masses of contiguous particles which are then subjected to steam treatment and thereafter drying to form coherent granules or agglomerates, the steam-treatment and drying steps being carried out in a manner such that there is no substantial relative movement between the contiguous particles of each individual mass. The steam with which the steam treatment is carried out is free from droplets larger than 0.1 mm. in diameter, and the drying step is conducted using hot air and/or radiant heat. Individual masses of contiguous particles of material deposited by a granulator 18 on a plastic or plastic-covered belt 8 are treated in a lagged chamber 19 with steam issuing from a number of tubes 68, are dried during their passage through a lagged chamber 20 by an electric radiant heater 79 and a current of hot air from a tunnel 80, and the dried granules or agglomerates are directed by a spring-tensioned scraper 93 into a quickly moving stream of cold air in the duct 88 by which they are conveyed to a cyclone for collection. The steam chamber 19 has a steam-heated jacket 65 and a detachable inspection plate 92 heated by steam pipes 91. The material may be forcibly fed into duct 88 by a worm to subdivide the granules or agglomerates into smaller masses. The material may, for example, remain in the steam chamber for 4-11 seconds and in the drying chamber for 5-16 seconds, the average temperature in the drying chamber being 175- 190‹ C. and the temperature of the heated air flow to the drying chamber being 100-110‹ C. Specification 810,813 is referred to.

Filed: 1946-10-18
Abstract: 629,612. Calculating-apparatus. MARTIN CO., G. L. Oct. 18, 1946, No. 31037. Convention date, Oct. 26, 1945. Addition to 596,302. [Class 106 (i)] [Also in Groups XX and XXXIII] An apparatus for determining the longitudinal position of the centre of gravity and gross weight of a seaplane afloat, as described in the parent Specification, is modified in that the means for indicating the longitudinal position of the centre of gravity is connected to pressure - determining means arranged near the plane of the aerodynamic centre and to further pressure-determining means arranged at a point remote from the aerodynamic centre in the longitudinal direction of the seaplane. The gross weight is indicated by means actuated only by the pressure - determining means arranged near the plane of the aerodynamic centre. The indication of the longitudinal position of the centre of gravity is obtained from a pointer read either against that scale, of a number of scales, which corresponds to the indicated gross weight, or if only one scale is provided, against the scale which is adjusted manually or automatically in accordance with the gross weight. Two pressure-determining means are arranged, one on either side of the seaplane, near the plane of the aerodynamic centre, to allow for true indications when the seaplane is rocking or is tilted during loading.

Abstract: 1,071,781. Thermal storage space heaters. ALEXANDER DUNN Ltd. Nov. 14, 1963 [Aug. 15, 1962], No. 31232/62. Heading F4U. In a thermal storage air heater a fan directs air through a passage extending around or through an electrically heated thermal storage mass, mixes the heated air re-entering the fan housing with cool incoming air, recirculates heated air through the passage and emits heated mixed air. The air from entry filter 24 passes through outside passage (23) into the fan housing and then through inside passage 22 and horizontal conduits (20) in the mass perpendicular to the heating elements and returns through inside passage 21 to the fan housing. Mixed air is emitted from the outlet 17 which has an auxiliary electric heater 18, and part is recirculated. The amount of air passing through the mass and thus the temperature of the emitted air is controlled by damper 25 which is automatically adjusted by thermostats 26A activating control means 27. Alternatively the damper 25 may be manually adjusted or dependent on the speed of the fan. The heating elements are controlled by thermostats 19A, and safety thermostat 26 is provided. In another embodiment the inlet is provided with damper blades at the heater inlet or outlet which control the pressure and temperature of the emitted air. The control means of this damper may be temperature dependent.

Title: Improved sealing device for pistons, stuffing-boxes, shock-absorbers and the like, and its various applications
IPC: F16J9/02
Filed: 1937-11-15
Abstract: 491,763. Shock-absorbers. MERCIER, J. Nov. 15, 1937, No. 31399. Convention date, Nov. 17, 1936. [Class 108 (iii)] [Also in Group XXVI] Comprises piston and stuffing-box packing of the cup-leather type, suitable also for shockabsorbers, wherein two packing-members face each other and enclose an oil-filled chamber which is divided by partitions, screens, &c. into at least two distinct spaces, or which communicates with an adjacent chamber. Small-section channels connect the spaces or chambers, and means are provided for maintaining the oil-pressure therein high and constant and at least one packing-element covered with oil. The hollow body 1 moves in a hollow cylinder or prism 2. Packing-members 3. 3a of metal or the like, face one another. A space 5 between the packings and divided into two parts by a wall 9, is connected through channels 6 with the interior 7 of the body 1. The wall 9 is formed on a sleeve 10 which supports sleeve 4 carrying the packing 3. A closing-cap 11 carries a valve 12 and a plug 13 to facilitate filling. The spaces 5, 7 are filled with a lubricating-substance or liquid. The space 8 has an air cushion. The spaces 5, 7, 8 are initially put under pressure exceeding that outside the body 1. Leakage of liquid is made good from the chamber 8. The spaces 5, 7 are free of air which construction prevents the formation of an emulsion. In the construction shown in Fig. 2, the chamber 25 which separates the packing-rings 18, 18a, is connected through orifices 27 to a chamber 24 formed in the rod, which is supplied with lubricant under pressure and contains an air cushion. In a modification of the construction shown in Fig. 2 for a vertical arrangement wherein the space 25 communicates directly with the channel 23, a disc is arranged around the sleeve, and is provided with narrow channels which connect the two sides of the chamber 25, to prevent the formation of an emulsion below the disc. Two or more discs may be used. In a construction suited for a horizontal position, the packing-members engage the pistonrod. A wall provided with right-angled, aircollecting channels separates the oil space into two parts at the top of which air collects. The air channels cause the air to collect on one side of the wall only. In a further modification of the vertical arrangement, the separation of the air is effected by a cup-shaped member on the lower part of the piston. In the construction shown in Fig. 6, the space 25e directly around the lips of the packing, is separated from the space 25d by a perforated, annular screen 33. A compression chamber or a lubricating-device may be included in this construction. The air which passes lips 18, 18a may be recovered by connecting the internal spaces containing air to air spaces outside through passages with valves having, e.g. capillary orifices, which permit the passage of air, but prevent the passage of liquid.

Abstract: 1,274,238. Identity cards. SAAB-SCANIA A.B. 23 June, 1969 [24 June, 1968], No. 31499/69. Heading B6A. An identity card or like document 1 such as a passport includes an area of randomly distributed particulate material 4 to form a random pattern 7, Fig. 2, which is not discernable to the unaided eye, the material being such as to be detectable by means yielding an electric signal. Finely-powdered magnetic material may be employed, so that if, after the material has been magnetized, the card is passed under a magnetic reading head scanning, for example, two straight lines a, b, electrical signals are produced depending on the random pattern. These signals are amplified and stored in a memory device. Two kinds of material having different characteristics may be employed. To prove the identity of the person concerned, the card must be scanned in a similar manner by a reader at the place where the card is presented and this reader must be connected to the memory device. The card 1 may be made of paper reinforced by plastic or of metal with or without a plastic covering. The material 4 may be deposited directly on the card or indirectly on a transparent film 5 which is attached to the card, and may cover a photograph 2 mounted on the card. An area of the card separate from the patterned area may contain the owner's sig. nature aud magnetically-readable numerals. To obtain more sharply defined signals, the patterned surface may be divided into squares by means of a screen pattern or by scratching away material along the sides of the squares. As an alternative to the squares, a strip of aluminium or aluminium alloy has a coating of a crackable lacquer applied thereto, the aluminium is stretched to form cracks in the lacquer, and the powdered material is then applied to the cracks. Two such strips, one superposed on the other, may be employed. Instead of ferro-magnetic material, fluorescent or resistively or capacitively detectable material may be used.
