Title: Improvements relating to photographic roll film cameras
IPC: G03B17/52
Filed: 1950-05-05
Abstract: 697,909. Apparatus for taking and developing photographs. HEAP, O. H. Aug. 3, 1951 [May 5, 1950], No. 11106/50. Classes 98 (i) and 98 (ii). In a roll film camera adapted to produce a negative and a positive immediately after the exposure of the film, a developing paste or liquid disposed in a container is extruded therefrom on to the exposed part of a light-sensitive or other light-sensitive strip by a piston disposed in the container and moved longitudinally thereof by the action of winding on the film, which action also brings the exposed part of the film into contact with a strip of printing paper to produce a negative on the film and a positive on the paper. Preferably the developer container is disposed in the core of a supply spool on which the film and the paper are wound together. As shown, a spool 4 on which is wound light-sensitive film and printing paper is hollowed to accommodate an independently rotatable cylinder 11 which contains a developer in paste form and which is connected by a pipe 13 to a distributer roller or tube 6 having peripheral openings, across which the film 3 passes as it is wound on after exposure by means of mangle rollers 7, 8, driven in unison by gears 22 (not shown) and 21, from a hand crank 9 on the shaft of roller 8. The film is pressed into contact with the printing paper 10, which passes behind the exposure gate, as they pass together between the rollers into a light-tight envelope 30, and the film and paper may be cut into single picture lengths by means of a knife or perforating device 31 on a pivoted member 32 by rotating the envelope 30 anticlockwise. Simultaneously with the feeding of the film, which itself rotates the supply spool, a contrate gear 23 driven by the gear 21 rotates a shaft carrying a second contrate gear 25 which in turn drives gears 26, 27 to rotate the cylinder 11, whereby a plunger 12, which is prevented from rotation relatively to the cylinder, either by keys engaging splines or by both cylinder and plunger being of hexagonal section, and which is formed as a nut on a fixed threaded rod 17, is caused to move axially in the cylinder to extrude through a nozzle 18a developer on to the film. In a modification, Fig. 1 (not shown), the container is fixed within the spool so as to rotate with it. The tube 13 which may be dismantled for cleaning is located in the camera by means of pegs 19 engaging sockets 20 in the camera so as to be readily removable both for this purpose and to facilitate threading the film and paper in the camera.

Title: Improvements in or relating to viscometers
Inventor: JOHNSTON JAMES STEWART
IPC: G01N11/14
Filed: 1968-03-07
Abstract: 1,204,259. Viscometers. ROSEMOUNT ENG. CO. Ltd. March 4, 1969 [March 7, 1968], No. 11143/68. Heading G1S. A cylinder 10 closed at its ends by plates 11, 12 contains the fluid to be measured and is itself surrounded by an oil bath which is thermostatically controlled through seals 20, 21 extend shafts 22, 23 integral with cylinders 30, 35 and secured to inner shafts 26, 37 provided with reduced diameter portions 31, 36 which form torsion couplings between the shafts 26, 37 and a boss 32 supporting a cylindrical member 34. Magnetic elements 40, 41 are arranged in the members 30 and 34 and their passage past datum points is detected by pick-ups 42, 43 connected by coils 44, 45 to a timer circuit and indicator 47. In operation the motor 27 runs at constant speed and drives the shafts and members 30 and 35. The driven member 34 lags with respect to 30 and 35 due to viscous drag and the angular lag depends on this torque and the torsional resilience of the couplings 31, 36. It is explained in the Specification how the time interval between the passage of each datum position depends only on the viscosity with a constant depending on the geometry of the viscometer so that the viscosity may be read out directly. The fluid may be slowly and continuously changed and the viscometer placed directly in the flow or in a by-pass loop. In Fig.2 (not shown) the arrangement is suitable for insertion directly in a tank or pipe-line and the viscous drag is between a cylinder (60) surrounding a cylindrical driven member (61) supported on a hollow torsionally resilient shaft (62). Photo-electric sensors (74), (75) are connected to a timer (76) and indicator (77). In Fig. 3 (not shown) the sensing means utilizes a vernier system (82), (83). In Fig.4 (not shown) the viscometer is installed in a pipe line (100) and a cylindrical member (101) is supported by drive shafts (102), (103) and the torsional deflection is measured as a time lag by using pick ups (111), (112) sensing the passage of magnetic elements (113), (114). In Fig.5 (not shown), which is a modification of Fig. 1, the drive members are similar to the members 30, 35 but are driven by fluid flow impinging on blades or paddles (123) and drive an intermediate member similar to the member 34 through a torsion coupling.

Abstract: 459,914. Brakes. STATTS, F. E., 400, Eckley Avenue, Peoria, Illinois, U.S.A. April 21, 1936, No. 11419. [Class 103 (i)] [See also Group XXIX] A hydraulic clutch of the radial slidable vane type is mounted within a fixed casing having plungers 36, Fig. 1, whereby the outer driven clutch element 11 may be braked. The element 11 is oval, and the interior of the casing and the exterior of the inner clutch element are circular to form crescent-shaped spaces for liquid. Filling plugs 56 are provided. The plungers 36 are normally pressed in by springs 38, which yield during movement of the element. By closing valves 41 by a hand lever liquid is prevented from circulating through passages 39, and members 43 are moved in a transverse bore in the plungers by the liquid pressure, so that the liquid obtains access to the backs of the plungers and prevents yielding so that rotation of the driven shaft is prevented. The plungers may be held out of contact by latches engaging spring-mounted latches 48 on the valves 41, as shown in Fig. 5. so that liquid may byepass around the plungers through passages 39 and there is then no braking action.

Title: A powdery calcium carbonate pigment
Inventor: LIGGETT LAWRENCE MELVIN
IPC: C08K3/26
Filed: 1958-04-11
Abstract: Pigmentary calcium carbonate, of particle size preferably 0.1 microns or less, is coated with a fatty acid compound and an amine in a molecular ratio of 1:1 to 7:1, the combined coating constituting from 2 to 3.5% by weight of the calcium carbonate. The fatty acid is one having 10 to 20 carbon atoms, a rosin acid or an alkali metal salt or lower ester of the rosin acid, whilst the amine is an n-alkyl amine containing 10 to 18 carbon atoms or a rosin amine.  Coating may be effected by blending an amine salt of a fatty acid with the calcium carbonate pigment and then with the fatty acid compound, or the order may be reversed.  The calcium carbonate may also be treated with an aqueous slurry of the amine and then hammer milled with the fatty acid compound, but preferably the calcium carbonate is treated with an aqueous slurry that contains an emulsion of both the alkylamine and the fatty acid compound.  According to Examples (1) calcium carbonate is treated with a C16 to C18 alkylamine derived from tallow, and stearic acid as an emulsion in water containing triethanolamine as emulsifying agent.  (2) An aqueous slurry of calcium carbonate was treated with an emulsion of the amine of (1) at 120 DEG F., filtered, washed and re-slurried and then treated with an emulsion of stearic acid.  Further examples refer to the substitution of stearic acid by lauric acid and the use as the alkylamine of decylamine, dodecylamine, dehydroabietylamine, or abietylamine.

Abstract: 712,367. Extruding insulating coverings on electrical conductors. SCHWEIZERISCHE ISOLA-WERKE. May 7,1952 [Nov. 23,1951, Jan. 30, 1952], No. 11586/52. Class 87 (2) A process for helically winding threads of thermoplastic material on a longitudinallymoving conductor by revolving extrusion orifices around the conductor, the conductor not being rotated on its axis, is characterised in that the material is fed from a stationary supply to passages leading without sliding joints to the extrusion orifices, these feed passages revolving around the conductor with the orifices and each passage containing a feed screw which rotates about its own axis. Figs. 1, 3 and 4 show a machine comprising a cylinder 10 to which is fixed an extrusion head 11 carrying a die 21a. The cylinder-extrusion head assembly is supported at one end by a ball-bearing 14 and at the other end by a bearing pin 13a, and is rotated by means of belts 25. As the assembly rotates, three conveyor screws 17 disposed in bores in the cylinder are rotated by engagement of gears 18 thereon with a central fixed gear 19, and feed three lots of differently coloured material to the die. At the die the material emerges through three ducts 11a in the die, and is wound around the wire 22 passing therethrough. The screws take their supplies of material from three stationary hoppers 20a having annular parts 20 which surround cylinder 10, the material being scooped into the screws by collectors 21 secured to the cylinder. The cylinder and extrusion head have electric heaters 23, 24 fed by slip rings. Fig. 5 shows a modification in which two screws 17 are rotated by engagement of gears 18 thereon with an internal fixed gear ring 26. The screws are fed by troughs 29, 30 which drop material into grooves 27, 28 formed in the cylinder 10 and the material is forced by scrapers fixed to the troughs Fig. 6. (not shown) from the grooves through holes 27a, 28a to the screws. Fig. 8 shows a modification in which the rotary speed of the screws may be varied independently of the rotary speed of the cylinder, the cylinder being rotated by belts 25 and the screws being rotated from a regulating drive 49 via gearing 48, 47, central pinion 45 and gears 44 on the screws. In this modification the screws slope towards the die. In other modifications (not illustrated) (1) the Fig. 5 machine may have its internal gear ring 26 rotably supported and driven whereby the rotary speed of the screws may be varied; (2) either form having an internal gear ring may be fed by the hoppers 20 of Fig. 1; (3) the screws of Figs. 1 and 5 may slope as in Fig. 8, (4) the screws of Fig. 8 may be parallel as in Fig. 1.
