Title: Improvements in and connected with pulverizing apparatus
IPC: B02C13/28
Filed: 1925-06-04
Abstract: 257,665. Tugwood, R. J., (Jeffrey Manu facturing Co.). June 4, 1925. Impact pulverizers.-In pulverizing- apparatus comprising a rotor carrying pivoted beaters, the beaters have restricted outward movement about their pivots from an inoperative position within the rotor to operative position in which they project from the rotor. Means may be provided for limiting the pivotal movement of a beater both inwardly and outwardly of the rotor. The beaters may be secured in their operative position by means of devices, such as small plates, which are broken under excessive stress to allow the beaters to move into the inoperative position. As shown, the beaters 10 are carried on rods 8, 9 which are arranged in pairs and pass through apertures in spaced discs 6 keyed to the horizontal driving- shaft 4. The beaters are preferably formed of a refractory alloy of iron and have a broad base portion 11 and an extension 12; they are pivoted on the rods 8 and have elongated apertures 14 through which the stop pins or rods 9 pass. The apertures 14 are concentric with the apertures 13 through which the rods 8 pass. The forward wall 16 of the hopper 15 is formed at its lower end with a shelf-like projection 17 extending into close proximity to the path of the beaters. Any fragment 18 of iron &c. present in the material led into the hopper 15 is intercepted by the abutment 17, and upon the beater extensions 12 contacting with the obstruction 18 they turn about their pivots 8 and pass the obstruction without injury to the machine. Thin plates 20 may be fitted into grooves 19 in the side walls of the apertures 14 to engage the rod 9 and hold the beater extensions 12 in operative position: when a beater contacts with an unpulverizable obstacle the plate 20 will be broken, thereby allowing the beater to turn on its pivot 8 and withdraw the extension 12 into the body of the rotor. The main frame 1 and the housing 2 carrying the hopper 15 are joined along the horizontal central plane of the rotor, and the semi-cylindrical flow of the pulverizing-chamber is formed of gratebars 5.

Title: Improvements in and relating to film-winding means for kinematograph projectors
IPC: G03B21/32
Filed: 1929-04-11
Abstract: 331,180. MacDonald, A. E., and Blunt & McCormack, Ltd. April 11, 1929. Divided on 331,012. Kinematograph apparatus.-In projectors for endless films, the coil of film is supported on edge on an annular table 4 rotated on the base 1 by means of a grooved pulley 50 engaging its edge and driven from the feed sprockets 11, 12, and the perforations of the film at the outer, and if desired also at the, inner periphery of the coil are engaged by sprockets driven at the same speed as the sprockets in the projector. The invention is described as embodied in a projector having the feed mechanism, gate and other parts described in Specification 331,012. The table. which may be flat or conical in shape, is supported by a fixed and a spring-controlled guide pulley 51, 53, and by the pulley 50 mounted on a vertical shaft 57 driven by a flexible shaft 58 and worm or skew-gearing from the feed mechanisms of the projector. Guard rails 68, 70 have openings by which the film is passed to and from the coil. The film, after passing through the projector, is guided by rollers 60, 61 to the sprocket 59, which returns it to the outer periphery of the coil. The roller 61 is mounted on a spring- controlled arm and may be designed as part of an electrical cut-off which comes into operation when the film breaks. The film is held in engagement with the sprocket 59 by a shoe 65<1> carried by a spring-controlled arm 65 which has a projection 66 for separating the rollers to allow threading of the film. Specification 250,183 also is referred to. According to the Provisional Specification. the supporting and driving pulleys are arranged to engage a depending annular flange on the table.

Title: Auto-process camera
IPC: G03B17/52
Filed: 1974-04-03
Abstract: 1408546 Self-processing cameras FUJI PHOTO FILM CO Ltd 3 April 1974 [5 April 1973] 14878/74 Heading G2A A self-processing camera for use with a cassette holding a stack of film units initially protected by a cover board has means for re-inserting the cover board into the cassette, so that this may be safely removed from the camera even though not all the film units have been exposed. As shown, the camera body has a passage 22 which is aligned with an exit slot (21), Fig. 8a (not shown) in the cassette, so that an exposed film unit 20 may be passed out of the cassette and out of the camera, during which movement it passes between processing rolls 24 in the usual way. The film units are initially protected against light by a cover sheet or board 19, which has to be removed before the first exposure is made. A pair of friction rollers 17 are mounted on a common shaft 16 which is carried in slots formed in a pair of push members 33. Members 33 are fixed to a shaft 32 which can be manipulated by a knob 8 extending exterior of the camera. When a cassette is loaded into the camera, the rollers 17 extend through small openings (18), Fig. 3 (not shown) in the cassette casing into contact with the foremost film unit. A motor is now actuated which drive the rollers 17 anti-clockwise (as seen in Fig. 8b), so that the foremost film unit is frictionally engaged and driven upwards until it is engaged by the processing rolls 24, which then take over the driving movement. If the cover board 19 is still in position, this is engaged first by the rolls and driven out, this being the situation shown in Fig. 8b. If knob 8 is turned clockwise, the front portions of members 33 enter the cassette openings (18) Fig. 9 (not shown), and engage and push the foremost film unit away from the front wall of the cassette. This enables the cover board 19 to be re-inserted in front of the film units, either through a separate passage 23 (as shown in Fig. 8e) or through the same passage 22. The operation of the push members 33 may be effected automatically by the re-insertion of board 19.

Title: Elastomeric products stabilised against changes in colour
IPC: C08C3/00
Filed: 1953-05-28
Abstract: Light-coloured elastomeric products are obtained from synthetic rubber latices prepared by emulsion polymerization, admixed if desired with natural rubber latex, by drying the product obtained by coagulation in the presence of a diphenyl amine substituted in the nucleus, and reducing agents.  The amine may be a reaction product of diphenyl amine with styrene, cyclohexene, or isoheptanol; and the reducing agents may be alkali metal salts of sulphurous, phosphorous, hypophosphorous and arsenious acids, or hydrogen sulphide; the free bases and salts of hydroxylamine or hydrazine; ferrous, titanous and stannous salts; glucose, aliphatic and heterocyclic mercaptans; salts of hydroxyalkyl-sulphinic and aromatic sulphuric acids; and esters of phosphorous acids, phenyl hydrazine sulphonic acids and phenyl hydrazine.  The synthetic rubbers may be polymers of butadiene-1,3, isoprene, and 2-chloroprene, and copolymers of these monomers with styrene, acrylonitrile, acrylic acid, methyl methacrylate, vinyl methyl ketone, and vinylidene chloride.  In an example (1) a reaction product of styrene and diphenyl amine was added to an aqueous emulsion of a butadiene-acrylonitrile copolymer with from 1 to 5 per cent of a reducing agent consisting of sodium polysulphide, glucose, sodium salt of hydroxymethane sulphinic acid, hydroxylamine sulphate, stannous chloride, dodecyl mercaptan, sodium sulphite, thiophenol or 2-mercaptobenzthiazole, and the mass coagulated and dried.

IPC: G08C21/00
Filed: 1965-04-08
Abstract: 1,048,356. Television. EBERLINEINSTRUMENT CORPORATION. April 8, 1965, No. 14892/65. Heading H4F. In an arrangement for interpretating images where the interpretation requires accurate observation of differences in density (e.g. of X- and gamma-ray films, photographs of camouflage, radar presentations of weather, appearances of actual objects &c.), video signals produced by a television camera 11 (Fig. 1) scanning the image 10 are supplied to a gate system comprising a monoscope 17 which produces an output signal only when the input signal has a predetermined value or values, such output signal being employed to unblank the beam of a picture tube 19 scanned synchronously with camera 11 so that the display on tube 19 comprises contours of the areas of image 10 which have the predetermined density or densities. For comparison, the actual image 10 may be reproduced on a further tube 14 or, by rapid operation of change-over switch 16, on tube 19 in alternation with the contour display. For producing the required gating action the target of the monoscope is formed with a plurality of ladder patterns (Fig. 2, not shown), the " rungs " being formed by a deposit of conductive material of low secondary emission (e.g. carbon) on a surface of high secondary emission (e.g. polished aluminium) so that an output signal is produced only when the electron beam of the monoscope impinges on the latter surface. In operation, the beam is directed horizontally to one of the ladders, depending on the width of the contour lines desired, by conventional coils or deflection plates and then directed vertically by an amount proportional to the amplitude of the video signal from camera 11 and by suitably controlling (e.g. by bias means) the initial vertical position of the beam or the gain of amplifier 13 a single contour may be produced for any selected density of the image. Different contour lines may be reproduced in different colours by replacing tube 19 by a colour tube the colour selection of which is controlled by signals derived from the monoscope as the beam passes the different " rungs." It is stated that the monoscope gate system may be replaced by monostable multivibrators or other known gating means.
