Patent GB-993353-A (GB)
Title: Article handling machine, particularly for removing articles from a pallet
IPC: B65G59/02
Filed: 1961-07-05
Abstract: 993,353. Packaging-machines; rollerway conveyers. FMC CORPORATION. July 6, 1961; No. 24220/61. Headings B8A and B8C. A machine for removing articles stacked on pallets comprises a feed conyeyer C carrying the stacked articles to a position over a table T which is raised so that the articles may be removed, layer by layer, by a reciprocating carriage TC, delivered on to a roller conveyer AC and transferred to a conveyer DC, the phases of the operation being controlled automatically by the articles or by moving parts of the machine. Loaded pallets are supplied, e.g. from a fork lift truck, on to the positively driven rollers 32 of the conveyer C. By engaging a switch LS 9 the pallet stops the drive to the conveyer C and energizes a motor to raise the table T. An end package, when raised on the table, touches a switch LS 1 to halt the table and start the drive to V-belts 113 which rotate the rollers of the carriage TC as it is advanced under the pull of its spring 95. The front roller of the carriage is positively driven in a clockwise direction so that it engages the first row of the top layer of the stack of articles and urges them to the rear, the articles passing on to frictionally driven rollers 140 of an accumulator conveyer AC. After each layer of articles is removed, a bar on the carriage TC operates a switch to return the carriage to the position shown in Fig. 2. The table is automatically raised by the spring 95 for removal of the next Layer in the stack. An intercepting plate 228, when touched by the first row of articles, breaks the drive to the rollers 140 and energizes the conveyer DC. A pusher bar 164 on the conveyer DC transfers the articles to a removal conveyer (not known), a further switch being contacted by a succeeding pusher bar to stop the conveyer DC when in position to transfer the next row of articles. A contact plate 256 when engaged by articles on the conveyer AC opens a switch thereby breaking the drive to the conveyer AC if articles are still being carried by the conveyer DC. After removal of the final layer of articles from the pallet, the table T is automatically lowered and the empty pallet returned to the feed conveyer C which takes it to the rear of the machine. In a modification, all the rollers on the carriage TC may be positively driven; alternatively, they may all be frictionally driven. Specification 993,352 is referred to.

Abstract: 990,053. Fluid-pressure servomotor systems. ANDRE CITROEN S.A. July 5, 1961 [July 6, 1960], No. 24320/61. Heading G3P. Control of an hydraulic motor 4 is effected in a first stage by a valve 1 which throttles the pressure fluid supply 13 to the motor and is actuated by a unit 2 in response to the load on the motor, and in a second stage by a servopiston 6 which adjusts the inclination of a swashplate 5 of the motor and is controlled by a piston valve 10 which is moved in response to the variations of pressure caused by adjustment of the valve 1. The valve 1 and the connection to the piston valve 10 may alternatively be in the exhaust conduit from the motor.

Title: Production of crystals
IPC: C30B15/36
Filed: 1960-07-13
Abstract: <PICT:0913675/III/1> In pulling a dendritic crystal by the method of Specification 899,058, the crystal is pulled between rollers arranged to prevent lateral displacement.  The crystal may be of germanium, silicon, or gallium or indium phosphide, arsenide, or antimonide. Gallium arsenide may be pulled in an atmosphere of arsenic.  The seed may be first wetted by the melt for a period of a few seconds to a minute, the melt then supercooled to a temperature of 5 DEG -15 DEG C. below the melting point in a period of 5-15 sec., and crystalpulling effected at a rate of 0,2-25 in./min.  The rollers may be of chloroprene rubber, polytetrafluoroethylene, polytrifluoromonochloroethylene, or a polyamide.  The pulled crystal may be wound on to a drum with a plastic interlayer.  The drum may have a variable speed and constant torque.  Optical sensing means responsive to changes in the thickness of the pulled crystal may effect control of the temperature of the melt and/or the rate of pulling.  Photo-electric or optical sensing means may effect operation of guide arms about the pulled crystal to provide additional control over the alignment thereof.  The thickness of the pulled crystal may be controlled by rapidly lowering the crucible from which the crystal is pulled a distance of 1-5 mm. and restoring the crucible to its original position over a period of 30 sec.  As shown in Fig. 1, a crystal 46 is pulled from a melt in a graphite crucible 18 heated by induction.  The crystal passes through an aperture in a lid 22, between two pairs of rollers 48, 50, 52, and 54, the axis of each being inclined slightly with the horizontal, and around a drum 60.  The melt is replenished from a reservoir crucible 181 of graphite connected to crucible 18 via an electro-magnetic valve 30.  A vacuum or an atmosphere of one or more of helium, argon, hydrogen, and nitrogen may be maintained in the outer container 36, which may be of glass or quartz.  The pulling force may be applied to one (Fig. 4, not shown) or both (Fig. 5, not shown) pairs of rollers and/or to the drum.  The rollers may have the same torque and different speed (Fig. 6, not shown) or vice versa.  Specification 894,241 also is referred to.

Title: Recovery of oil from spent clay used in the clay treatment of lubricating oils
Inventor: POLLOCK JOHN EDWIN
IPC: C10G25/12
Filed: 1951-10-19
Abstract: A process for the recovery of oil from clay that has been used in the clay treatment of lubricating oils and which contains entrained oil comprises contacting the used clay &c. with an extract obtained from the solvent refining of a mineral oil fraction to extract the entrained oil from the used clay and recovering the extracted oil from the solution of oil in the extract.  Clays &c., such as bentonite, fullers earths, magnesite, bauxite and alumina, which contain entrained oil after treatment of lubricating oils, may be agitated with the extract resulting from the refining of lubricating oil with a solvent, such as liquid sulphur dioxide, furfural, phenol, dichloroethyl ether and nitrobenzene.  If phenol or furfural has been used the extract may be used directly, but a sulphur dioxide extract should preferably be stripped of solvent before use.  The extract is preferably the aromatic extract from kerosine, but extracts from lubricating oils and gas oil may be used.  The clay may be removed by settling, filtration or centrifuging and reactivated or discarded, and the oil plus solvent may be distilled, the lubricating oil being removed as a distillate side stream or as a bottoms product. Fractions of the extract may also be removed.  The clay/solvent extract mixture may also be distilled, the clay being removed as a slurry in the bottoms.  A "chaser" may be included in the feed to the distillation stage to give a greater yield of lubricating oil.

In a machine tool, the feed movement of a slide 10 is interrupted by diverting a predetermined volume of hydraulic fluid from a line 26 controlling forward movement of the slide. The turret slide moves relatively to a fixed piston 20 and carries a tap 40 movable axially in a holder 36 secured to the turret 32 by an expanding mandrel 38. A valve 54 governs the rate of feed. When a dog 68 on the slide trips a switch 64, a valve 58 is operated to divert a volume of fluid into a cylinder 73, the volume being set by a screw 78. The slide thus dwells while the tap feeds itself. In a modification, the tool is a drill and the feed is interrupted a number of times to break up the swarf. In a further modification, the valve 58 is mechanically operated.

The bearing element having the strip of polymer is made by roughening parts of the surface by etching or grinding, and after cleaning, the elements are dipped in a suitable resin. Excess resin is removed from the surface other than at the roughened portion and the elements dried. They are then heated to below the decomposition temperature of the polymer to cause the polymer to creep slightly over the bearing surface.
