[Also in Divisions B3 and E1] A forging hammer, pile driver, screw press or the like has its tup 1 actuated by a linear electric motor. The tup is connected to a reaction rail 3 which co-operates with one or more drive units 4 on the frame 5 for raising the tup. Alternatively the reaction nail may be stationary and the drive unit or units connected to the tup. Various cross-sectional shapes of reaction rail, and relative arrangement of drive units are described, Figs. 20-24 (not shown). Where a plurality of drive units are used, they may be energized selectively in dependence upon the required intensity of the blow. The tup may fall by gravity or the drive units may be reversed to assist gravity. Switches 7, 8, 9 control the units 4 to give one or successive blows. The switches 8, 9 are adjustable for varying the stroke. Buffers 11 cushion the upstroke which is braked by reversing the units 4 or by braking means 10 which also operates if the electricity supply fails. Two opposed tups may be operated simultaneously in either a vertical or horizontal arrangement, Figs. 6, 7 (not shown), alternatively a single horizontal tup may be used. The invention may be applied to the tup (32) of a pile driver, Figs. 18, 19 (not shown), for driving metal or concrete piles (30). In other embodiments, Figs. 8-15 (not shown), the linear motor is used to drive the flywheel of a screw press.

Filed: 1968-08-16
Abstract: 1294654 Separating fibres G ROBERTS 12 Nov 1969 [16 Aug 1968] 39183/68 Headings D1F and DIN Fibres are separated according to length by feeding fibrous material on a first card clothed roller 24 through a zone of cooperation with a second card clothed roller 26 or 28, there being a point-to-point action between the card clothing of these two rollers. The relative peripheral speeds of the rollers and the inclination of their teeth are such that at the output side of the zone of cooperation, the shorter fibres tend to be held by the slower speed roller 24 and be detached from the faster speed roller, 26 or 28 and the longer fibres tend to be held by the faster speed roller 26 or 28 and be detached from the slower speed roller 24. As described, the short fibres are then cleared from slower roller 24 by a fly comb into coil guide 46. The longer fibres are then transferred via brush roller 30 or 32 to doffers 34 or 36 where from the longer fibres are formed into a sliver. In alternative embodiments, the faster rolls 26 or 28 can be provided with an additional slower speed roller (58) to remove further shorter fibres, or the slower roll 24 can cooperate with a further roller strain to remove further longer fibres.

[Also in Groups XX and XL (b)] A liquid level indicator comprising a light guide, the operation of which involves the movement of liquid into and out of contact with a surface of said light guide, is provided with means for facilitating removal of adherent liquid from said surface on movement of said liquid out of contact with said surface. Light from a source 3, Fig. 2, undergoes a plurality of total internal reflections on the faces 7, 16, 8 before reaching a detector 6. When liquid is in contact with any of faces 7, 16, 8 which may be in separate vessels, reflection is replaced by refraction and the output of detector 6 falls. To avoid liquid sticking to the faces 7, 16, 8 they may be made as part of larger surfaces. A plurality of such detectors spaced vertically may determine the range within which the level lies or a detector may be coupled to a feed-back system to follow the liquid level. In a modification, the light guide comprises a hollow cylinder 21, Fig. 3, with a conical end 28, an inset block 24 serving both to reflect light to a phototransistor 30 and provide a continuous drain path from the surfaces 22.

Title: Parking installation for motor vehicles
IPC: E04H6/36
Filed: 1961-11-07
Abstract: 950,368. Mechanical garages. A. T. DE SAINT-ANDRE. Nov. 7, 1961 [Nov. 10, 1960], No. 39860/61. Heading B8E. In a mechanical garage of the kind in which parking sites 2, 3 are arranged in pairs facing each other across a central driveway 1, each site has an associated car-supporting platform or set of platforms movable between the site and the driveway and each facing pair of sites has an associated control system whereby it is ensured that when the platform set of one site is moved to or from the driveway the set of the other site normally moves with it. This conjoint movement is, however, prevented whenever the platform set of both sites of a pair are loaded, so that if e.g. site 2 is occupied by a car 6 the platform set of site 3 may move loaded from the driveway into site 3 without deparking the car 6 in site 2. In the illustrated form, a platform set comprises a pair of platforms 4 (for site 2) or 7 (for site 3) movable together by cables 10, 11 driven by electric motors 18, 19 of which the former controls the movements of platforms 4 and the latter of platforms 7. The motors 18, 19 are energized from power lines X, Y. Z (Fig. 3) to move in the required direction on operation of switch arms 24a, 24b respectively, the motors being cross-connected to ensure their normal conjoint operation. The switches 21A, 21a, 21B, 21b are end-of-travel switches operated automatically at the end of a platform movement (see also Fig. 2). The mechanical interconnection of switch arms 24a and 24b by bar 32 is such that when one of the arms has been moved into the position in which it effects parking of a car (e.g. by causing switch 29a to connect motor 18 to lines YZ), the subsequent placing of the other arm in the corresponding position is ineffective to depark the previously parked vehicle since the cross-connection of the motors is broken at 31a and 31b. This occurs because the yoke 27 of each of the switches mounted on bar 32 is then against its lower stop 35. Normally movement of either switch arm causes pivoting of bar 32 about its central pivot 33 to ensure maintenance of the motor interconnection at 31a or 31b. Two alternative electrical control systems and one fluid-pressure control system (Figs. 4, 5 and 6, not shown) are described. In some of these a motor may drive the platform set of one site only and the conjoint motion is effected by physical pushing of one platform set by the other.
