[Also in Division E2] Each lower corner of a box pallet side wall carries a platform-engaging fitting which is rotatable about, and slidable to a limited extent in the direction of, an axis in the plane of the side wall and which incorporates means for preventing such rotation when the wall is in its position of use. In Fig. 3 the wall has hollow end posts 3a into each of which is fitted an upstanding peg 10 integral with the fitting 8 which engages the pallet 1 as shown. A stop 13 on the fitting's upper surface normally engages the lowermost horizontal member 12 of the side wall to prevent rotation in use. To detach the side it is lifted to clear this stop and the pair of fittings (only one of which is shown) are oppositely rotated to disengage from the pallet. The adjacent side wall is detachably secured to the fitting by means of complementary formations 17, 18, 19 (Fig. 3), or 25, 26 (Fig. 4, not shown), on the fitting 8 and the corner post 4a of the adjacent wall.

Filed: 1954-01-05
Abstract: 751,102. Reciprocating pumps. AUTO RESEARCH CORPORATION. Jan. 5, 1954 [Jan. 5, 1953], No. 288/64. Class 102(1). A lubricant pump comprises a piston G loaded by springs H and lifted on its suction stroke by a lever E having a roller 101 that engages a cam D. The cam is driven by a shaft B through a worm 38 and a train of reduction gearing mounted on shafts 63, 64. The cam has a pin Q that enters a slot N in the pinion 62 ; the slot extends about 180 degrees around the pinion. A torsion spring 87 engages the pin Q and a projection 90 on the pinion 62 and in addition a blade spring R engages the pin Q and is sufficiently strong to overcome the resistance of the spring 87 and hold the cam stationary until it is moved by the end of the slot N engaging the pin Q. By this arrangement, when it is desired to operate manually by lifting the sleeve L, the cam D is in a position, or is moved to a position by the spring 87, that it does not prevent a full stroke of the piston G. The pump is fitted with a filter K and the sleeve L is adjustable to vary the stroke. The pump delivery passes through the chamber 165 adjacent the porous bearing sleeve 30 for the shaft B. The pump and actuating mechanism are carried by a cover A for a lubricant reservoir.

Title: Improvements in or relating to the Charging of Gas Retorts.
Inventor: WHITE ALFRED ERNEST
IPC: C10B31/06
Filed: 1916-01-07
Abstract: 103,137. White, A. E., (Riter-Conley Manufacturing Co.). Jan. 7, 1916. Charging.-Charges for retorts are standardized Loth as regards quantity of material and shape, so that when a charge is finally deposited in a retort, it assumes a predetermined configuration or distribution, which can be repeated for successive charges. The heating of the retorts is controlled by any usual means to correspond with the predetermined distribution. The invention is described in connection with a known form of doublescoop charging-machine, each scoop of which consists of two sections movable one over the other. The coal is fed from a hopper 38 by an endless band 39 to a weighing or measuring bucket 36, which can be rotated to dump the charge through a shoot 34 into the scoops. The depth of material across the band 39, and hence the distribution of the charge along the length of the bucket 36. is determined by the inclination of the forward edge of the outlet from the hopper 38. The charge in the scoops is shaped by wing mechanism of the kind described in Specification 103,139, and by a roller 41 beneath which the scoops move during their advance into the retort. The charge is deposited by closing the two sections of each scoop one over the other and then inverting the scoops, and while the action necessarily changes the configuration of the charge, it will not appreciably vary the distribution of the charge along the length of the retort, except at the ends, where the material seeks its angle of repose. The charge is preferably so formed that the retort is filled to within a short distance of the top, leaving only sufficient space for the swelling of the charge and for the passage of the gas. The charging-machine may be controlled by the means described in Specification 103,138, and the retort bench is preferably of the type described in Specification 8507/15.

[Class 102 (i)] A fuel-injection pump in which the pump piston 7 and the cylinder 6 move downwardly together until the end of the cylinder engages the seat 21 and shuts off the suction port 3 when delivery through valve 22 commences. A wedge-shaped surface 13 on a sleeve 10 is secured to the piston by screw threads and during the delivery stroke, the surface 13 moves the balls 15 which act against the conical surface 16 and lifts the cylinder 6 whereby delivery ceases. The sleeve 10 is adjusted relatively to the plunger by a rack 20 mounted on a rod common to other pumps and engaging teeth on the sleeve. A port in the spring abutment 24 is smaller than the port in the seating 21 so that when the valve 22 closes drip is prevented.

A valve unit operated by a solenoid 15 for controlling compressed air operating clutches and brakes for steering vehicles, comprises a magnetic material casing 14, 14a with a valve seat 18 and containing a non-magnetic sleeve 11 which, with a cavity 9 in a non-magnetic manifold head 2 having a valve seat 17, forms a chamber 12 containing a magnetic material plunger 10 with end valve inserts 21 co-operating with the seats. Normally spring-loaded pins 25 move the plunger to close exhaust port 17 and allow air to pass from port 20 via slots in the plunger to a port 4. Energization of the solenoid closes port 20 and connects ports 4, 17. The closure members 21 are of neoprene and prevent magnetic sticking, help to push the plunger away from the ports when necessary and may be reversed about their attaching pins 22 to prolong wear. The inlet and exhaust ports may be reversed in use. Several units may form an assembly with a common manifold head 2. Specifications 642,205, [Group XXIV], and 666,568, [Group XXXI], are referred to.
