Title: Improvements in or relating to methods, devices and materials for developing photographic emulsions
IPC: G03D5/06
Filed: 1961-03-06
Abstract: 973, 222. Development of photographic emulsions. W. ZINDLER, [trading as LUMOPRINT ZINDLER K. G.]. March 6, 1961 [March 17, 1960], No. 8104/61. Heading G2A. In a method of developing a photographic emulsion, the developer substance is distributed heterogeneously as solid material in a normally solid body of flux material, the flux material being converted to a liquid state by the application of heat and/or liquid, and then being brought into relatively moving contact with the emulsion. In the arrangements shown, the developer material is provided in the form of a so-called "chemical" roller (Fig. 10). This has an axially fluted core 95, on which is an outer chemical layer 96 in which the developer material is bonded with a readily fusible or soluble material. The particular example given has a mixture of borax and soda crystals. In the arrangement of Fig. 7, this chemical roller is shown as 64, and rotates in contact with a pressure drum 65, the film being fed between them from inlet 69 to outlet 70. The upper drum 65 contains a heater 102, which melts the surface of the lower drum, and so enables the developer material to be applied to the film. Alternatively, or in addition, the surface of the chemical drum can be moistened, either directly or by means of an intermediate roller. The two rollers or drums are spring-biased into contact. The lower roller 64 is power-driven, and the upper drum 65 rotated by contact therewith. The upper drum may be slowed down by a brake, so that there is a stronger frictional effect between the two rollers than that caused merely by driving contact. Fig. 8 shows a double arrangement, the first chemical roller 76 containing developer substances and the second chemical roller 77 containing fixing substances. Fig. 9 shows a different double arrangement, for a transfer process, comprising chemical rollers 81, 82 and pressing or heating drums 83, 84. The two films are subsequently pressed together between rollers 92, 93.

Title: Vehicle brake testers
IPC: G01L5/28
Filed: 1930-03-14
Abstract: 348,284. Dynamometrical testing of vehicle brakes. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Cadwell- Baird Iron Works; 4503, Alger Street, Los Angeles, U.S.A.) March 14, 1930, No. 8326. [Class 106 (ii).] A device for testing road vehicle brakes comprises a supporting structure having a movable member thereon on which a wheel of the vehicle is received, means for producing a force tending to move the vehicle in the direction of movement of said movable member, and means for measuring the reaction of the member against translational force imparted thereto by the said wheel. The structure comprises horizontal channel members 10, 11 the flanges 13 of which point upwardly, the ends of the members being inclined to form ramps. Clips 37 under the members 10, 11 support spindles carrying rollers 16 which project through openings in the web of the members to support the runners 39 of the wheel receiving members 17. A cylinder 21 pivoted to an extension 19 of the structure encloses a piston 23 the rod 24 of which has a hub 27 at the extreme end and also a hub 28 which moves over ratchet teeth 28a with which a pawl 30 normally engages. The hub is tilted by a lever 33 against the influence of a spring to disengage the pawl. Projecting from the members 17 through slots in the channel members 10, 11 are projections 42 hinged to plunger rods 43 of cylinders 44 to which are connected pressure gauges 46. A footoperated portable control valve 54 is provided for the cylinder 21. The ends of pipes 52, 53 are connected by flexible tubing to the cylinder 21 and to the valve device 54. The hollow valve body 60 encloses a rotatable plug 61 to the stem of which is connected levers 63, 64. When the lever 64 is lowered, the central passage 66 supplies compressed air through passage 67 and port 68 and the pipe 52 to the rear end of the cylinder and the piston 23 is moved forward. During this time the pipe 53 is connected through the port 70 and passage 71 with the discharge port 72. When the lever 63 is moved down, the pipe 53 becomes the supply pipe and the pipe 52 is open to exhaust the piston being moved in the opposite direction. In use, the vehicle is run on to the members 17 and the hubs 27, 30 caused to engage the front axle. The valve device 54 is placed on the floor of the vehicle near the driver. The brakes are then applied and air admitted to the cylinder 21 to move the piston in the direction of the arrow in Fig. 1 and apply a pull to the front axle. The applied brakes will resist rotation of the wheels and a pressure will be built up in the cylinders 44 which is measured by the gauges 46. The vehicle is restored to original conditions by pushing down the lever 63. In a modification, the platform formed by the rails 10, 11 is inclined and the vehicle is hauled on to it by a winch mounted on an extension of the platform. The brakes are then applied and gravity is used instead of the force exerted by the cylinder 21 which is dispensed with.

Abstract: 425,793. Electric signalling systems. BAILEY METER CO., 1050, Ivanhoe Road, Cleveland, Ohio, U.S.A.-(Assignees of Ryder, J. D.; 11448, Euclid Avenue, Cleveland, Ohio, U.S.A.) March 22, 1934, No. 8988. Convention date, March 25, 1933. [Class 40 (i)] [See also Group XXXVI] A measuring-apparatus comprises a measuring circuit connected across a source of current and including an impedance, and a sensitive circuit subjected to a voltage derived from this impedance and including a voltage-sensitive device which is subjected to voltage variations in accordance with variations in a variable to be measured. These voltage variations are neutralized by varying the current in the measuring circuit so that this current is a measure of the variable to be measured. The Figure shows an arrangement for measuring the temperature of a furnace 15 by measuring the voltage generated by a thermocouple 6, which is balanced by the fall of potential in a resistance 1 when the current flowing therein is adjusted so that a galvanometer 12 gives zero deflection. The resistance 1 is included in the plate circuit of a thermionic valve 18 in series with an ammeter 2 and the secondary winding of a transformer 25, the primary winding of which is connected to the supply mains in series with an ammeter 39 and a recording instrument 40. The moving system of the galvanometer 12 carries a mirror 26, which, when deflected from its zero position, reflects a light ray on to one or other of two photo-electric cells 29, 30 which control the potential of the grid 19 of the valve 18 and thereby control the current in the plate circuit so that the fall of potential across the resistance 1 is equal to the voltage generated by the thermo-couple 6. The reading of the ammeter 2 is then a measure of the voltage generated by the thermo-couple 6, and therefore of the temperature of the furnace 15. The transformer is arranged to give a high voltage on the secondary side so that the primary current measured by the indicating and recording instruments 39, 40 is proportional to, but of higher value than, that indicated on the ammeter 2. Small currents may similarly be measured by measuring the voltage drop across a resistance. Alternating currents or potentials may be measured by interposing rectifiers. In order to change the range of measurement, the resistance 1 may be provided with tappings for connection to the galvanometer 12. In a modification, a resistance thermometer is connected in place of the resistance 1, the moving system of the galvanometer 12 being biassed towards its zero position by means of a spring, or otherwise. Similar means may be employed for measuring any physical, electrical, thermal, or chemical quantity such as fluid rate of flow, pressure, &c. Reference has been directed by the Comptroller to Specification 399,641, [Group XXXVI].
