Title: Improvements in or relating to programmed electro-hydraulic control devices
IPC: G05B19/06
Filed: 1962-04-06
Abstract: 950,030. Machine tool details. PRODUMATIC. April 6, 1962 [Jan. 29, 1962], No. 13246/62. Headings B3B and B3K. A programmed electro-hydraulic control device wherein a working section is controlled according to a preset programme by means of interchangeable cams formed by rods having bosses, and associated contacts actuated by the bosses during movement of the working section by an hydraulic cylinder, characterized in that the working section is detachably connected by hydraulic pipes, and electric conductors to a separate power section comprising a source of pressurized liquid feeding the hydraulic cylinder of the working section. A milling head 3, Fig. 1, in the working section 2 is driven from a power section 1, the latter including pumps 6, 7, Fig. 3, driven by an electric motor 5, which supplies fluid from a sump 4 to a cylinder 45 to thus move a carriage 43 on which head 3 is mounted. Programming rods 28, 29, 31, Figs. 1, 2, are carried by carriage 43, and co-operate with switches 48, 49, 51, to control the movement of the carriage. Section 1 also includes adjustable spring-loaded valves 9, 11, 12, and solenoid-operated valves 13, 14, 15, and a valve 55 for controlling the end of the carriage stroke, which is actuated by a valve 44 which co-operates with a stop 59 on the carriage. Programming rod 28 controls the stopping and starting of motor 26, rod 29 controls the emission of signals during the cycle which are supplied to another device to carry out a further set of operations, or to the same device to carry out a further cycle, and rod 31 controls the rate of travel of carriage 43. In an automatic operation valves 9, 11 are adjusted, rods 28, 29, 31 are positioned on carriage 43, and valve 14 is opened. Fluid is pumped to both ends of cylinder 45, the pressure at end 45a being greater than that at end 45b and the carriage moves at a fast rate. Enlarged end 28d of rod 28 actuates switch 48 and milling spindle motor 26 is started. Enlargement 31d on rod 31 then actuates switch 51 and valve 15 is energized to pass some of the fluid from conduit 52 through valve 12 and back to sump 4, thus reducing the feed rate during the working period. At the end of the work period, stop 59 opens valve 44 which actuates valve 55, and switch 56 stops the feed, and valves 14 and 15 are de-energized, thus reducing pressure P1 and allowing carriage 43 to be retracted. Carriage 43 can be moved in a step-by-step fashion by controlling the movement of valve 13.

Abstract: 477,037. Viewing objects by infra-red light. KUNZ, J. May 18, 1936, No. 14106. Convention date, May 18, 1935. [Classes 97 (i) and 98 (i)] An image of the object is produced by an optical system on an excited phosphorescent screen, the stored-up energy of which is driven out as visible radiation in proportion to the intensity of the infra-red light thus forming a positive image which is observed directly. Phosphors such as sodium or caesium bromide in which the light - quenchable luminosity is greater than the heat-quenchable luminosity may be used and the phosphors may be excited first by exposure to cathode or X-rays and then to visible light. As shown in Fig. 2, light passes through a lens 7 and is reflected from a prism 8 to the phosphorescent screen 9 heated or cooled by a substance in the container 13, observation being effected through a lens 10. The apparatus shown in Fig. 3 contains an exciting lamp 22 which illuminates the screen 16 by way of a lens 23 and a prism 24 when an opening 21 in a circular shutter 18 registers with the lens 23 in which position of the shutter the other two apertures are closed. Rotation of the shutter covers the lamp and allows infra-red light to fall on the screen via the lens 15 and prism 14. In Fig. 4, the screen 26 is rotated intermittently about an axis 27 so as to be excited by the lamp 28. Suitable phosphors for the screen may be the Lenard Phosphor CaSPb or ZnSMn, or sodium or caesium bromide. Crystals of rubidium chloride or potassium chloride withdrawn from a fused melt may also be used. Specification 294,671, [Class 97 (i)], is referred to.
