Title: Lift truck
IPC: B66F9/20
Filed: 1971-06-29
Abstract: 1342407 Lift trucks BYGG-OCH TRANSPORTEKONOMI (BT) AB 29 June 1971 [1 July 1970] 30468/71 Heading B8H A lift truck comprises a mast 8, load carriage having a pair of forks 9, an hydraulic lifting ram 5 operatively connected to effect movement of the forks 9, the hydraulic system which includes the ram 5 including pre-set and adjustable pressure regulating valves 3, 7, Fig. 3, which control the pressure in the cylinder 5 and thus the lift capacity of the lift truck. Up to a certain point on the mast 8 the pre-set valve 3 controls the supply of oil from a tank 6 to the ram 5, the load capacity being constant up to that point, at which point the adjustable valve Y takes over and decreases the lift capacity linearly, the said valve being adjusted by means of a wire 10 connected thereto and to the load carriage at 11. In a second embodiment of the hydraulic system for the lift truck, Fig. 5 (not shown), three fixedly set pressure regulating valves (20), (21), (22) are arranged in parallel and have supply conduits provided with electrically controlled stop valves (17), (18), (19) respectively which are normally shut-off when a pre-set valve (3) controls the pressure to the lifting ram, but are opened when the load carriage reaches heights (h17), (h18), (h19), Fig. 6 (not shown), the opening being effected by means of limit switches (not shown) placed on the mast. The pressure in the lifting ram is thus reduced from a maximum pressure (Pmax), which prevails therein when the valve (3) is operating, to a minimum pressure (P22) which is the pressure to which the valve (22) is set, when the load carriage reaches its highest point on the mast.

Title: Helical winding of a strip onto a tube
IPC: B21C37/26
Filed: 1975-07-22
Abstract: 1452879 Making helically finned tubes BALCKE-DURR AG 22 July 1975 [31 July 1974] 30515/75 Addition to 1444220 Headings B3E and B3A A plurality of flanged strips are wound on edge on to a tube to form a multi-start helical fin. In the embodiment shown, strips 13, 14 from reels 13b, 14b are flanged in roller devices 3 and wound on to a rotated oval section tube 1 at diametrically opposed points. Each strip is pressed against the tube by a guide 7 on arm 6 pivoted at 5 to a frame 4 and urged to contact the tube by a gas cylinder 8. Each guide comprises a shoe 10 riding on the tube, and blades 11, 12. The device 3 bends up the flange 13a, 14a by more than a right angle, and blades 11 have correspondingly bevelled ends. Blades 12 are not so bevelled, and reform the flange to about a right angle. A pressure roller 9 on shoe 10 resiliently urges the strip against blade 11 to tension the strip and stretch it immediately before it bends around the tube. In another embodiment, three strip reels and guides are spaced around the tube. The frame and reels are moved along the tube by lead screw mechanism (not shown), operated synchronously with the tube rotation, over a bed on which the tube is supported. On reaching the foot of the bed, the frame, reels, and wound tube are all advanced together until the frame reaches the head of the bed and can recommence winding. When a tube is finished, a fresh tube is joined end to end to the old one by a spigot adaptor, and when a reel is exhausted, the beginning of a new reel is welded to the end of the old, so that winding can continue indefinitely. Each strip runs over a pulley arranged so that breakage of the strip stops the machine. Cooling fluid is directed on to the strip guides 7 to remove the heat developed in the strip by friction. The wound tube may be hot galvanized, the coating metal penetrating into the gap between strip and tube by capillary action.

Abstract: 250,639. K. D. P., Ltd. Dec. 19, 1924. Addition to 213,886, 214,583, and 219,277. Latex, treating; plastic compositions containing indiarubber.-The latex paste of the parent Specifications is mixed with gradually added vulcanizing and/or compounding ingredients under such conditions that the paste does not lose its reversible properties, until a foamy paste is formed, which paste is then dried. The latex paste should preferably contain 75-90 per cent of solids, and the compounding ingredients are added as a dry powder, a paste, an emulsion or solution, with or without the addition of protective agents to prevent coagulation in a mixing machine with as little friction as possible. It is preferable that the amount of free water in the mix be kept at about 25 per cent. The mix may be made to retain its reversible properties by careful drying, even though vulcanized latex has been used. Intense drying, pressure, or the addition of coagulants renders the mix irreversible. The mix may be worked directly into articles or it may be dried and plastified by work. ing on rolls which may be heated. The plastified mass obtained thus is softer than the ordinary masticated rubber and may be squirted, e.g. to form tubes. In an example 40 parts of sulphur, 100 parts of zinc oxide, 6 parts of oil red G, and 344 parts of whitening are incorporated with 400 parts of caoutchouc latex containing 75 per cent of solids and the mass is dried. The mass is passed for 5 min. between rollers and introduced into a squirting machine.

Abstract: 617,678. Magnetic ceparators. ELECTROMAGNETS, Ltd., BOX, W. E., and CLARIDGE, J. T. Oct. 16, 1946, No. 30735. [Class 72] An electro-magnetic separator of the over band type has associated with the main coils 16a of the electro-magnets 16 additional coils 16b which are automatically brought into circuit to increase the ampere-turns and hence the magnetic field intensity, when the field due to the main coils falls to a pre-determined amount due, for example, to over-heating of the main coils. The separator consists of an endless band 7 disposed above and transverse to the material conveyer 4, the band passing round drums 8a, 8b and being driven by an electric motor 9. The height of the band above the conveyer may be adjusted by screw bolts 13, and the band may have magnetic feelers 7a. Magnetic material is retained on the belt by an auxiliary electro-magnet 18 until over the discharge chute 17, whilst any magnetic material carried round by the belt falls into a chute 19a and is returned to the conveyer 4 for further separation. The current relay 21 and its associated contactor 22 are so designed that when the intensity of the field due to the main coils 16a falls below a pre-determined value the contactor of relay 21 closes under spring pressure and completes the circuit through the relay and contactor 23 associated with the coils 16b, thus bringing the latter into circuit with coils 16a. A non-magnetic screen (e.g. of brass) 19b protects the magnets. Specification 617,680 is referred to.
