Title: Improvements in or relating to the filling of cartridges and apparatus therefor
Inventor: LAZARI FABRIZIO
IPC: F42B33/02
Filed: 1957-09-24
Abstract: 826,199. Cartridge - filling machines. MONTECATINI SOC. GENERALE PER L'INDUSTRIE MINERARIA E CHIMICA. Sept. 24, 1957, No. 18677/57. Class 9(1) A machine for filling cartridge cases comprises case-feeding and holding mechanism together with explosive feeding mechanism terminating in a nozzle having sliding fit in a case such that as the case fills there is relative movement between the nozzle and the case, the operating cycle of the machine being controlled by correct completion of the relative movement. Furthermore both mechanisms are operated by fluid pressure controlled by a set of distribution boxes actuated by a cam shaft and preferably the fluid is oil. The explosive is fed from a hopper 1, Fig. A, through slit 2 surrounded by an ebonite sheath 3 to a helical screw 4 extending through the nozzle 5. The screw 4 and an agitator 6 in the hopper are driven through a dog-clutch 10 and a V-belt 8, the toothed gearing and connecting linkage being enclosed in an oil bath. The empty cases are fed from a hopper 25, having an inclined reciprocated base, to a conveyer belt 24, which is controlled by a chain drive 31. From the belt the cases enter a collector 23 and are thrust from there by a piston 22 into a sleeve 15 3  mounted on a rotary head 14. A piston 16 carries a projection 17 which engages the head 14 and rotates it to bring the empty case to the filling position. After each rotary step the head 14 is stopped by a clamp 21. When the empty case reaches position 15 1  a piston 32, Fig. A, is aligned therewith and by way of a distribution box 34 controls the start of the filling cycle. The filled case is ejected by a piston 35, Fig. B, at position 15 5 , the mouth of the case having been closed at position 15 1  by means of a piston 36, which through a rod 39 also operates pistons 41 to hold the cartridges in position during rotation of the head 14. The cases are sealed at position 15 6  by means of a piston 46 which operates a set of hammers (not shown). Faulty positioning or a defect in a case is detected by means of a light source 67 aligned with position 15 2  and a photo-electric cell 68, Fig. A, the cell when activated by the light beam operating a relay to stop the machine. A micro-switch 69 is aligned with the shaft of distribution box 34 so that if there is a defect in the functioning of the machine, e.g. due to faulty feeding of the explosive the switch closes to stop the machine. The control devices may be connected to visual and audible warning signals. A motor driven fluid pressure generator is connected to the various parts of the mechanisms by conduits.

[Also in Group XXI] A device for indicating the relative position of the line of thrust of a jet-propelled aircraft or rocket, and the longitudinal axis, when at rest, comprises members supporting the weight of the machine before take-off, being deformable under the weight of and forces applied to the aircraft, combined with means for comparing their deformations at different values of thrust. In Fig. 4, a rocket 1 rests on four members 14 having pistons 6 within cylinders 5 filled with fluid. The two cylinders of each diametrically opposite pair of cylinders communicate with either side of a piston 8 within a cylinder 7. A rod 9 extending from the piston 8 is normally centred by a spring 10 and bears an indicator 12 movable by piston 8 with respect to a datum 13, If the thrust of the jet-propulsion unit does not pass through the centre of gravity G of the aircraft, but deviates by an angle α, the reactions on the members 14 will be unequal, and the indicator 12 will move from datum 13. Only three members 14 may be used. For non- vertical take-off, rollers 20 (Fig. 5) support one component F 1  of the weight, and members 14 support the component F 2 . If desired, the cylinders 5 may be mounted on the aircraft together with the indicator, the pistons 6 being on the ground.

Title: Improvements in or relating to electron discharge devices for use in television or like systems
IPC: H04N5/74
Filed: 1939-06-28
Abstract: 530,591. Light modulating; cathode-ray tubes ; television. BAIRD TELEVISION, Ltd., and WILLANS, P. W. June 28, 1939, No. 18788. [Classes 39 (i) and 40 (iii)] Relates to electron discharge devices for use in television of the kind in which the electron beam modulates the electric potential of a mosaic screen producing therein corresponding changes of transparency or reflecting power, for example as described in Specification 454,589. According to the invention, instead of the electron beam being modulated in intensity, modulating potentials are introduced at 6 between the common electrode 7 of the mosaic screen and the electron gun 5, and the individual electrodes 8 of the screen are adapted to be charged by secondary emission to the potential of the most positive conductor in the device. In consequence, a potential difference is produced between each individual electrode 8 and the common electrode 7 corresponding to the modulated signal potential at the moment the electron beam strikes the electrode 8, and this difference of potential persists until the electron beam again strikes the cell. The optical variations in the screen are utilized in known manner; for example the screen is used in conjunction with a light source 1, polarizers 3, 9 and lenses 2, 10 for throwing an image on a viewing screen.

Title: Improvements in textile spinning machines including ring rails and annular balloon limiters
IPC: D01H1/42
Filed: 1955-06-29
Abstract: 778,637. Balloon control means. BREMATEX. June 29, 1955 [July 5, 1954], No. 18819/55. Class 120 (2). A textile spinning machine including a ring rail and an annular balloon limiter, the ring rail being arranged to have, beyond the end of its normal movement, a supplementary or underwinding stroke, is characterized in that each balloon limiter is carried by the ring rail through a retractable support such that the balloon limiter normally held at a substantial distance from the ring rail during the normal movement thereof, is retracted to a position very close to said ring rail, so as to clear the space surrounding the cop, in response to the production of the underwinding stroke of the ring rail so as to effect this retraction of the balloon limiter during the underwinding stroke. In the arrangement shown balloon limiters 3 are carried by the ring rail 2 through a retractable supporting system (lazy tongs 5) which permits the shifting of the limiters from their normal position shown to a lower position in which they are adjacent the ring rail 2. For controlling the operation of the lazy tongs when the underwinding stroke begins two cams 8 rigid with the frame of the machine are provided, these cams having vertical edges 8a and concave lower edges 8b which co-operate with the pins 9 on the lazy tongs 5. Vertical plates carried by the frame of the machine are also provided the edges 7 and 10 of which serve as guides for the lazy tongs device during its folding. The edges 7 also prevent the folding down of the tongs during the normal stroke of the ring rail.

Title: Bacteriostatic compositions
IPC: A01N25/02
Filed: 1957-06-17
Abstract: Starch sizes for applying to paper and textile materials are preserved against attack by bacteria and fungi by the addition of an emulsion in water of a solution in a water insoluble solvent, e.g., a hydrocarbon or ketone, of a water insoluble phenol, preferably orthobenzylparachlorophenol.ALSO:A bacteriocidal composition comprises an oil-in-water emulsion of, in the oil phase, a water-insoluble phenol and a water-insoluble organic substance which dissolves or solubilizes the phenol, and in the water phase a major proportion of water, which composition is capable of dilution with water to a level of about 5 to 6 parts per million of its water-insoluble phenolic ingredient without impairing its bacteriostatic effectiveness. Specified phenols are orthobenzylparachlorophenol, 2,2-methyl-bis-(3,4,6-trichlorophenol), dihydroxydichlorodiphenyl-methane, 1-hydroxy, 3-methyl, 4-chlorobenzene; 2,4 - dichloro - 3,5 - dimethylphenol, orthophenylphenol.  The water-insoluble organic substance is conveniently a water-insoluble organic solvent, e.g. xylol and mineral oil or di-isobutyl ketone in which the water-insoluble phenol is dissolved, and a dispersing agent, e.g. potassium lignin sulphonate for the solvent solution of the phenol may also be present.  Preferably, the composition also includes an emulsion stabilizer, e.g. gum ghatti, gum arabic, polyvinyl alcohol, methyl cellulose or carboxymethyl cellulose.  The development of odour in starch sizes used in paper making is eliminated by incorporating therein these bacteriostatic emulsions.

Abstract: 1,097,331. Moulding ceramic articles. SECRETARY OF STATE FOR DEFENCE. May 16, 1962 [May 26, 1961], No. 19069/61. Heading B5A. [Also in Division H4] Thin-walled ceramic articles, e.g. radomes, are produced by depositing a coating of ceramic material on the surface of a rigid form capable of elimination by oxidation, firing the coating in a reducing atmosphere with the form in situ and thereafter lowering the temperature until the ware is firm enough to stand without support and then changing the atmosphere to an oxidizing one to eliminate the form. The ceramic coating is preferably 98% pure alumina which is flame sprayed on to a graphite form. The temperature reduction prior to oxidation is preferably about 10%. In an example, the ware is fired at 1700 C., the temperature reduced 1550 C., oxygen introduced to eliminate the form and the ware maintained at this temperature for 24 hours before cooling. The ceramic ware may be machined before firing, and the process is preferably accomplished by machining the form on a copying machine, replacing the machine tool with a spray gun, spraying the form on the same machine with a ceramic coating of slightly more than the required thickness and machining this coat to the desired contour and thickness after allowing for possible shrinkage in firing and finally firing the ware as indicated above.
