A device for facilitating the loading of pallets &c. comprises a carriage 5 reciprocated between a loading position (as shown) and an unloading position, the carriage having mounted on it a turntable 9 for supporting a pallet, and the turntable being given a partial revolution during its traverse away from and towards the loading position so that a fresh portion of the pallet area will be presented for loading. The carriage 5 runs on rollers 4 on a frame 1 and is reciprocated by crank means 15, 16 driven by a motor 3. The turntable is supported by rollers 10 and has pins 19 protruding from its underside. Articles to be loaded, such as sacks, are fed to the loading position by a conveyer (not shown) and placed singly on a pallet on the turntable. A switch is thrown either by an operator or by the conveyer to initiate a single complete reciprocating movement. As the carriage travels away from the loading position, one of the pins 19 engages an abutment 26 causing the turntable to rotate and bringing the following pin 19 in line with a guide rail 24. On the return of the carriage, the following pin trips the abutment 26 as it travels along the rail 24. The loading end of the conveyer may rise intermittently to facilitate stacking several layers of articles on the pallet. Specification 770,001 is referred to.

Abstract: In the production of films, wrappings, sheets, threads, plastic compositions, and moulded articles from organic cellulose esters that are insoluble in acetone, the citric acid ester of an aliphatic or hydroaromatic alcohol is incorporated into the cellulose ester.  The citric acid ester may constitute as much as 60 per cent of the whole composition.  Examples of suitable esters are amyl citrate, butyl citrate, cyclohexyl citrate, or amyl dibutyl citrate.  A highly flexible film containing 25 per cent citric acid ester may be prepared by spreading on a roller or endless band a solution containing 15 parts by weight of cellulose triacetate, 72 parts of methylene chloride, 8 parts of ethyl alcohol and 5 parts of triamyl citrate.  A suitable silk spinning mixture consists of 100 parts cellulose triacetate, 350 parts methylene chloride, 75 parts of alcohol and 15 parts of triamyl citrate, and a composition suitable for making a film consists of 30 parts of cellulose triacetate, 120 parts of methylene chloride, 20 parts of ethyl alcohol, and 9 parts of cyclo-hexyl citrate. Compositions may be made suitable for use in the electrical industry.

Abstract: 398,377. Control systems for consuming-devices. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Assignees of Stansbury, C. and Brown, G. C. ; N. 12th Street, Milwaukee, Wisconsin, U.S.A.) Dec. 9, 1932, No. 34962. Convention date, Dec. 10, 1931. Addition to 370,002. [Class 38 (iv).] In the thermionic time-delay device described in the parent Specification in order to prevent the reclosure of the controlled circuit by the reclosing of the control switch before the requisite time delay period has fully elapsed, the discharge circuit of the grid control condenser is completed by a relay the operation of which is independent of the control switch. As shown in the Figure applied to an electric welding plant the relay 10 has its coil 11 in the anode circuit of the valve 15 and is normally energized by plate current through the valve the discharge circuit for the grid condenser being broken at contacts 14. When the control switch 5 is opened the change in potential of the grid due to the insertion of the resistance 21 in series with resistances 22, 20 across the supply L<1>, L<2> causes a cessation of plate current in the valve 15 and the discharge circuit of condenser 19 through resistance 23 is completed at contacts 14. The opening of contacts 13 thus renders any subsequent reclosure of the control switch 5 ineffective during the time period which elapses until the valve again becomes conducting when the relay 10 is again energized and the welding circuit 3, 4 is broken by de-energization of relay 6 controlling the primary circuit 2.

Abstract: 1286405 Reciprocating pumps or motors K R DIXON 20 July 1970 [28 July 1969] 34994/70 Heading F1A A radial pump or motor comprises a relatively rotatable shaft 2 and cylinder block and casing assembly 4, 12, pistons 7 in the block slidably bearing against flats 42 in casing 12 which is eccentrically mounted relative to the block. The working pressure in the cylinders 6 is transmitted to flats 42 via bores 13 and recesses 14, the area of the recess being slightly less than the crosssectional area of the cylinder, so that radially outward hydraulic forces are borne directly by casing 12, apart from a slight force for maintaining the pistons in contact with flats 42. The radially inward forces due to the working areas of the cylinders are balanced by the forces due to the effective areas of recesses 37. Shaft 2 is formed as a pintle valve with distributor grooves 21, 22. Radial forces between casing 12 and shaft 2 are balanced by recesses 56, Fig. 4, in the casing sequentially registering with recesses 31, 32 corresponding but directionally opposed to valve ports 21, 22, and connected to the ports by passages 26, 27. Block 4 and casing 12 are coupled by followers 41 on block arms 39 engaging recesses 40 in casing 12. In alternative embodiments, Figs. 11 to 15 (not shown), the eccentricity of the casing relative to the block is adjustable hydraulically, and the cylinder block comprises a plurality of separate cylinders located by clamping ring assemblies. Sealing arrangements for the pistons, cylinder block and pintle are described, Figs. 5 to 10 (not shown).

Member 29 is biassed by spring 27 upwards against frustoconical plastics cover 30, which has windows (40) through which green, yellow and red portions of arms 36 of the member are visible successively as movement of the valve 20 to its by-passing position rotates member 29. Slot 35 is constructed so that the member is rotated in the reverse direction when valve 20 closes, but the member also has a triangular slot 41 (Fig. 4, not shown) which can alternatively engage pin 31 so that the member rotates when valve 20 opens but remains in its new position when the valve closes to indicate .that the valve has been open. Knurled extension 45 of member 29 enables manual resetting. Passage 51 (Fig. 1) allows trapped air to bypass element 14.
