Filed: 1936-05-15
Abstract: 476,934. Guided-platform load-handling machines. YALE & TOWNE MANUFACTURING CO. May 15, 1936, No. 13789. Convention date, June 7, 1935. [Class 78 (iii)] A lifting truck of the kind in which the load is supported on two uprights which may be retracted so as to move the load from the rear towards the front end of the truck, the uprights being tilted about a predetermined axis during such retraction, is characterized in that the uprights are given a movement of translation longitudinally of the truck in addition to said tilting movement, and means are provided for locking the uprights against such movement of translation until they have been tilted to a predetermined angle. In the embodiment shown, the truck comprises control and load-carrying portions 10, 11 connected to one another by means described in Specification 476,991, [Group XXXI], and load-supporting forks 45a which are raised and lowered on a pair of uprights 30 by a chain 43, Fig. 5, driven from a motor gear 41 by a pinion 42. These uprightsare secured to base-portions 31 supported on rollers 32, 33 which, when the uprights are at the rear end of the truck engage in grooves 56, 57 in side plates on the truck-portion 11. The uprights are moved forwardly on the truck by pinions driven by a gear 40, engaging racks 36 secured to the uprights. During the initial movement of the racks, the uprights are held against longitudinal movement by the rollers 32 engaging the grooves 57, and thereby tilt until these rollers reach the grooves 56. The uprights then move forward on the truck until the axle 46 of the rollers 33 engages an extension 90a on a pivoted bar 90 to actuate a control rod 80 through levers 87, 85 and stop the drive 40. The return movement of the uprights to the rear of the truck is terminated when the rollers 32 re-enter the grooves 57 and engage a bell-crank 32a connected through a rod 100 and lever 84 to the control rod 80. The drive 41 is shut off when the forks 45a reach their extreme positions on the uprights, by a rod 70a secured to the forks, which, in the lower position, engages directly a lever 71, secured to a control rod 75, and in the upper position, engages a lug 73 on a rod 74 secured to this lever. Control of the drive 41 is effected from the portion 10 of the truck by a handle connected through a rod and a universal joint to a sleeve 61 on a square rod 60, which is itself connected by a universal joint to the control rod 64. When the forks are in their lower position, they engage a pivoted member 53 so as to displace a rod 48 against the action of a spring 49 and pivot a roller 52 down into a position such that if the uprights are tilted, the roller engages the extension 90a to stop the drive 40, thus preventing the forks damaging the rear axle of the truck.

Title: Improvements in or relating to methods of reclaiming electric lamps or thermionic valves
IPC: H01K3/30
Filed: 1935-05-10
Abstract: 450,039. Thermionic valves. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Birdseye Electric Co. ; Commercial Street, Gloucester, Massachusetts, U.S.A.) May 10, 1935, No. 13807. [Class 39 (i)] [See also Group XI] In a method of reclaiming electric incandescent lamps and thermionic valves the mount is severed in such a position that an annular rim of its material is left attached to the neck of the bulb outside the original line of seal between the bulb and mount while the position of the neck relatively to the bulb remains unaltered, the annular rim being subsequently reshaped. The severing of the mount may be effected by a flame from a burner or by grinding. As shown in Fig. 1, a flame from a burner 30 is directed upon the inner portion of the flare 16 of the bulb 10, the lamp being rotated about a vertical axis during this process. Heating is continued until an annular zone of the flare is softened, whereupon the leading-in wires 26 are grasped by jaws 32 and pulled outwardly until the softened flare 16 and stem-tube 18 are drawn into the form shown in Fig. 4. The mount is then severed by the flame from a burner 34, either in the position shown or nearer to the original line of seal 14. Alternatively the drawing out of the flare may be dispensed with, the severing being effected entirely by the burner 30, Fig. 1. After the removal of the mount the collar or rim 21, Fig. 6, may be again heated by flames from burners 36, 38, and reshaped by rotating it against a downwardly extending spindle 40. In the operation of severing the mount by grinding, the end of the bulb formed by the convex flare of the mount or by the portion that has been drawn out after softening, is placed against a grinding wheel and rotated slowly whilst in contact therewith, the end of the bulb being cut through to leave a rim projecting outwardly beyond the original seal line. The grinding operation is facilitated by heating the bulb.

Title: Control circuits
IPC: F16K17/10
Filed: 1974-03-29
Abstract: 1414288 Excavators POCLAIN 29 March 1974 [5 April 1973] 14116/74 Heading E1F [Also in Divisions F1 and F2] If a lever 53, Fig. 1, is moved to the left in the Fig., interlinked valves 5, 33 are moved to their first positions in which a chamber 7 of an actuator 4 is supplied from a pump 1 and fluid from a chamber 9 returns freely to a reservoir 3. Fluid from a chamber 31 returns to the reservoir through pipes 34, 35, 32. This allows a spring 27 to depress a piston 29 so that pushers 25, 26 bear on slides 10, 16 to keep pipes 8, 19 open. In the two other positions of the valve 5 the pipe 8 must be perfectly sealed except when feeding fluid to the chamber 9. This is achieved by feeding fluid under pilot pressure to the chamber 31 through pipes 38, 34 to raise the piston 29 so that slides 10, 16 are held up by a spring 18, thus blocking pipes 8, 19. In the third position of the slide 5 automatic piloting of the slide 10 is provided. Fluid from the pump 1 flows through pipes 11, 8 to slide 10 where it is stopped, and into a guide 14. The latter moves the slide 10 to open pipe 8 so that fluid can enter the chamber 9 and fluid from chamber 7 can return through pipes 6, 12. As soon as pressure falls in the pipe 8, e.g. when valve 5 is moved to its second position, slide 10 is moved by the spring 18 to close pipe 8. The circuit shown in Fig. 3, (not shown) operates in a similar manner.
