Title: Improvements in or relating to apparatus for coating the interiors of containers with flowable material
IPC: B05C7/04
Filed: 1944-10-11
Abstract: Apparatus for coating the interiors of containers with flowable material comprises means for delivering flowable material to an article to be contacted by said material, means for maintaining the flowable material under pressure necessary to effect delivery of the material, a valve interposed between said two means for controlling the delivery of said material, and a restricted bye-pass passage for affording communication between said two means independently of the condition of said valve. Referring to the diagram, coating units D are mounted at the top of the apparatus and are adapted to receive inverted containers X-Y which are to be coated.  A pump E is immersed in the coating fluid F in the tank B with its discharge passage 19 arranged to deliver coating fluid under pressure into a pressure manifold 20 fitted with a conventional pressure relief valve connecting back to tank B.  A heating packet C keeps the fluid in F heated by heat transferring fluid 14.  Downward pressure on container X forces the support 56 downwardly and moves the valve piston 44 to disengage the valve disc 43 from the seat 42.  In this position the heated fluid F flows upwardly through openings 49, to chamber 50 and so through recess 51 and openings 52 and bore 53 into tube 55 and out under pressure to flood container X.  Excess fluid from the container passes out through openings 59 in the support 56 and so back to tank B.  To avoid the tendency of the fluid to congeal in the relatively <PICT:0585621/III/1> <PICT:0585621/III/2> cool delivery tubes 55 when valve 39 is closed, each valve piston 44 has a small opening 62 communicating with bores 53 under tube 55.  Hence when valve 39 is closed fluid flows slowly up opening 62 bore 53 and tube 55 keeping the fluid in motion in tube 55. The opening 62 is of such small flow capacity that the fluid passed therethrough flows slowly down the outside of tube 55 and through draining openings 59 without being ejected substantially above the top of the tube 55 and without coming into contact with the container X.

Abstract: 943,584. Moving wheels laterally of vehicle. J. B. NICOLAS. May 22, 1962 [May 25, 1961], No. 19723/62. Heading B7D. The loading platform of a vehicle is supported on each side by two wheels 2, 3 mounted in tandem on a common longitudinal member 4 which is connected to the frame by two wheelsupporting arms 5, 6 preferably of equal length, each pivoted to both the frame and member 4 so that the wheels may be swung laterally of the frame beyond the normal lateral limits of the vehicle's loading platform. Pivotal movement of the arms 5, 5a on the two sides of the vehicle and hence lateral movement of the wheels is controlled by rotation of rod 13, the ends of which are oppositely threaded and are engaged by nuts connected to the arms 5, 5a by links 16, 16a. Inadvertant outward movement of the arms is prevented by pawl 18 engaging ratchet-wheel 17 on rod 13. The plane of wheel 2 is normally maintained parallel to the vehicle longitudinal axis XY by hub extension 20, the end 21 of which engages spring-loaded cam member 22 on the loading platform. Rod 19 (Fig. 3) maintains wheels 2 and 3 parallel. In a modified arrangement the pins on which the wheel support yokes 26, 27 are mounted are slidable vertically in the members 4, the upper ends of the pins 9, 10 either engaging a load equalizing beam 28 (Fig. 5) or a pair of levers 30, 31 (Fig. 10) pivoted to member 4. The levers 30, 31 are interconnected by a pneumatic or hydropneumatic ram 34, the fluid pressure of which may be varied to alter the vehicle height. Additional locking means for the wheels 2, 3 comprise spring-loaded notched plates 44 (Fig. 5) which engage the V-shaped upper ends of the pins 9, 10 and may be withdrawn from the pins by lever 48.

Abstract: 536,721. Variable - speed gearing. AUTOMOTIVE ECONOMY CORPORATION. July 8, 1939, No. 19973. Convention date, July 21, 1938. [Class 80 (ii)] Change-speed gear selection and actuation are interconnected with the engine throttle so that gear shifting means is operated upon disengagement of the clutch, such means being under the control of the throttle-actuation for selecting the desired gear. The clutch disengaging-means may also be throttle-actuated and both clutch operation, with consequent gear shifting, and gear selection may be power-actuated, for example, from engine intake-suction. As shown in Fig. 3, the accelerator pedal 1 is provided with cams 22, 3, linked to the throttle 31 and a valve 5. Opening of the valve results in engine suction from the manifold 28 through the pipe 35 acting on the cylinder 18 ; movement of the piston puts the clutch pedal 27 in disengagement position. A valve 26 connected to the pedal 26 then opens to engine suction one or the other side of the piston in the cylinder 20, this piston being connected to the gear shifting lever 8 the direction of movement being determined by the two-way valve 19 connected to the pedal 1 and therethrough related to the throttle-setting. The lever 8 is connected to a valve 7 in the pipe 35 whereby the valve 5 may be rendered inoperative for permitting manual control of gears other than those controlled through the cylinder 20. In another construction, Fig. 4, electrically controlled valves are used for gear-shifting. Between the pedal and the throttle 31 is the linkage 36, 37 anchored to the frame through links 38. 39. The link 39 rests on a part 41 of the pedal 27, movement of which to disengage the clutch thus permitting the links 36, 37 to fall and move the throttle to idling position. At the same time the connection 68 opens the valve 47 and engine-suction acts through pipes 48, 49, selector valve 50 on the cylinder 51 and gearshifting lever 52. The position of the selector valve 50 is determined through solenoids 53 connected to a switch 55 controlled from the pedal 1. The gear-shifting lever 52 is also connected to solenoids 58 by which the valve 59 is thrown over as the gear changes to vent the piping to atmosphere and re-engage the clutch 27.
