Filed: 1974-01-11
Abstract: 1464151 Automatic writing apparatus FEEDBACK INSTRUMENTS Ltd 28 Feb 1975 [11 Jan 1974] 01319/74 Heading G3N Writing apparatus for use in a remote writing system is designed to accept a ball point pen as a stylus connected through a linkage to low inertia electric motors in a receiver, potentiometers in a transmitter or both in a transceiver. The receiver shown has a housing 10 which supports a paper roll 13 and includes a writing area 12. The pen 21 is coupled through the linkage to shafts 28, 29 which are rotated by belts 33, 34 driven by pulleys 35, 36 attached to the motors. The motors include printed circuit armatures and are of.pancake shape to reduce the height of the equipment and provide high torque. The shafts 28, 29 are mounted on a cradle pivoted on pins 40 and moved by solenoid 49 to lift the pen from the paper. A spring 46 biases the cradle into a pen engaging position. In a transmitter the construction is similar except that the pen is biased away from the paper and a writing area switch is used to provide the pen lift signals. Additionally the servomotors are replaced by potentiometers which signal the movement of the pen linkage. The transceiver includes both potentiometers, motors on writing area switches and uses a modified cradle which replaces spring 46 with a solenoid which when energized provides the pen engaging pressure for receiver operation and is de-energized to free the pen for transmission. The transmission system, which may be over telephone lines, uses a multi-frequency signal to represent the movement of the pen and the various switch signals. Operation of one transmitter or transmission by a transceiver is arranged to inhibit operation of the other transmitters, or prevent transceivers transmitting, connected to the system.

Filed: 1933-01-14
Abstract: <PICT:0401525/III/1> Pitch and similar colouring materials are removed from sheep wool by treating the wool with the vapour of a volatile solvent, cooling the wool, expressing the condensed solvent by pressure, and then washing the degreased wool with an alkali solution.  A tank 1 is divided into two chambers A, B, which are provided with a communicating door 2 and are traversed by rails 4 carrying an open-mesh truck 5 containing the wool.  Solvent such as hexalin, tetralin or trichlorethylene passes from a reservoir 19 to the lower part of the chamber A containing a heating element 33. Solvent vapours rise through the wool contained in the truck and are condensed by a cooling coil 22 mounted in the upper part of the chamber.  After the vapour treatment the truck passes to the cooling chamber B, and the wool containing condensed solvent is pressed by a falling weight 24.  Expressed solvent falls into a tray 30 and returns to chamber A through a pipe 31.  The wool is then removed from the truck and washed with soap or soda solution. In the degreasing operation the solvent vapours may be forced into the wool under pressure, and the wool may be loosened to assist penetration of the vapours.ALSO:<PICT:0401525/IV/1> Pitch and similar colouring materials are removed from sheep wool by treating the wool with the vapour of a volatile solvent, cooling the wool, expressing the condensed solvent by pressure, and then washing the degreased wool with an alkali solution.

Title: Improvements in and relating to television and like systems
IPC: H01J31/40
Filed: 1936-01-16
Abstract: 469,033. Cathode ray tubes. LUBSZYNSKI, H. G. Jan. 16, 1936, No. 1483. [Class 39 (i)] In a television or like system a mosaicscreen 3 is permeable by an electron beam supplied from a gun 5 and suitably deflected over the mosaic ; on the side of the mosaic remote from the gun the beam impacts on a target electrode 12, Fig. 1, to liberate secondary electrons which may be collected by an output anode 14 direct or after further impact on one or more target electrodes 13, suitable focusing coils 17, 18 being provided. An optical image is focused on the mosaic which has a grid-like form with photo-electric sensitive elements 9 ; the photo-electron emission from the elements controls the electro-static potential of the screen and thereby influences the strength of the beam from the gun passing through the mosaic A positively biassed shield 11 protects the target 12 from the mosaic and a grid 10 collects the emitted photo-electrons from the mosaic. To reduce the speed of the electron beam to the mosaic, the latter may be stabilized at cathode potential or a decelerating grid may be placed before the grid 10. The mosaic is formed of a mesh of fine, glass or enamel-covered wire with a layer of silver on one side, baked to break the silver into discrete elements, which are caesium coated. The charges on the elements of the mosaic may leak away slowly to the wire coils of the mesh forming the base of the mosaic. As shown the beam impacts the mosaic normally and the image projection is inclined ; these conditions may be reversed. The anode 14 may be in the form of a fluorescent screen ; the device may then be used as an image amplifier. With a high frequency multiplier, one 21 of the impact electrodes 21, 22 has a gap through which the beam from the mosaic may pass for multiplication; with this construction, if the optical image is projected normally on the mosaic and the electron beam at an angle, slats may be provided to cover the aperture in the electrode 21, the sides of these slats remote from the mosaic being coated to act as part of the electrode 21.

Title: Hydraulic control for dies in ram type presses
Inventor: WILLIAMSON FLOYD MITCHELL
IPC: B21D22/00
Filed: 1966-01-13
Abstract: 1,142,121. Stamping. DI-DRO ENG. CO. 13 Jan., 1966, No. 1651/66. Heading B3Q. A crank-operated press comprises a die 20 moved to a retracted position by a punch 22 on the ram 14, and an hydraulic cushion for resisting retraction of the die and returning it to its extended position upon opening of the press, the hydraulic cushion comprising a cylinder 56 having a piston 54 movable with the die, a tank 58 containing hydraulic fluid under pressure and connected to the cylinder to bias the die to its extended position, and further hydraulic pressure means 104, 112 operable by the crank-shaft 12 for supplying fluid at a pressure higher than the tank pressure. As the die 18 recedes, the punch 22 and a cooperating die-opening 26 shear a blank from a sheet, the blank being then drawn between an inner punch 34 and a co-operating die 18 to form a cup 36. Supporting the die 20 from the compound piston 50, 54 is at least one rod 46. The inner die 18 is mounted on a piston 80 and retracted by a spring. Fluid from the tank 58 is fed, through a valve-body 88, to the piston 80 and, through a further valve-body 66, to the piston 54. A direct connection 60 is provided to the low-pressure piston 50. A pressure-relief valve 74, controlling the escape of fluid from cylinder 56, provides the required resistance to retraction of die 20 as the press closes, the larger piston 50 assisting in returning the die and stripping the work. Work-stripping is also assisted by raising the central die 18 by fluid supplied supplied at higher pressure by the piston 112 operated by the crank-shaft and passing through valve-body 88. The die 18 may be advanced at, or before, the press is closed. In a modification, Fig. 2, (not shown), which does not have a low-pressure piston 50 or a valve-body 88 and in which the central die (118) is immovable, high-pressure fluid from the crank-operated piston 112 is fed beneath the small piston (52) for stripping the work. In another construction, Fig. 3 (not shown), the high-pressure piston (112) is driven from the crank-shaft by a connecting rod (300), otherwise the press is similar to that of Fig. 1. Alternatively, Fig. 4, the piston 112 may be driven by gearing and a crank from the crankshaft 12. In another construction, Fig. 5 (not shown), similar to that of Fig. 1, except that there is no large piston 50, two coaxial high-pressure cylinders (104) are used, which are operated by cams (324). One of the cylinders supplies the cylinder (82), as in Fig. 1, and the other the cylinder (56), as in Fig. 2. Reference has been directed by the Comptroller to Specification 1,031,204.
