Filed: 1973-09-27
Abstract: 1438578 Bag-filling apparatus HALK BV 27 Sept 1973 [29 Sept 1972 3 Nov 1972] 45387/73 Heading B8C A filling apparatus for valve bags includes a filling tube 5 and bag-engaging members in the form of part-shells 3, over which a bag may be applied, and which are caused, in use, to move parallel to the axis of the filling tube 5 and to rotate so that, as they move upwards their lower ends move away from each other and position a valve bag around the filling tube in a filling position. Each shell 3 is secured by a bracket 8 to a slide block 2 having pins 7, 7<SP>1</SP> which slide respectively in grooves 6, 6<SP>1</SP> in a base-plate 1 so that, in their downwardly extended position they substantially cut off the bottom end of the filling tube 5. After applying a valve bag to the part-shells 3 in their lowermost position a switch, not shown, can be actuated to operate, e.g. an air cylinder, not shown, which has a rod 4 connected to the slides 2 to raise and pivot the shells 3 to their retracted positions, as shown in dotted lines 10, Fig. 1, so that the valve of the valve bag is drawn closely around the lower end of the filling tube 5 where it is clamped against the shells 3, e.g. by two pneumatic clamps, not shown. After the bag has been filled the clamps are removed and the guide shells are moved downwardly so that the filled bag is released and the bottom end of the filling tube is again shut off. A vibratory filling apparatus, Fig. 3 (not shown), comprises a hopper (11) which is joined by a flexible sleeve (12) to a filling tube (13) having a spout (14) and a pair of shells, not shown, a motor (16), acting through a crank (20) and a connecting rod (18), being adapted to vibrate the filling tube (13) axially with respect to the hopper (11).

Title: Hydraulic transmission systems for winches
IPC: F15B21/04
Filed: 1961-12-22
Abstract: 999,797. Hydraulic transmissions. LEWIS STRAND, [trading as LEWIS STRAND HYDRAULISK VENSJEFABRIKK OG MASKINVERKSTAD]. Dec. 22, 1961 [Dec. 24, 1960], No. 46057/61. Headings F2C and F2D. [Also in Division B8] A winch control system providing for two conditions of operation, viz. mooring (in which the line tension has a substantially constant and relatively low value) and hauling (in which the line tension is variable and appreciably higher) is characterized by means for increasing the line tension whilst the control is in the mooring setting to allow for a temporary hauling-in of the moored load. The invention consists in an hydraulic transmission powered by two pump cells 10, 11 (shown separately, but in fact driven by a common shaft 14). The first pump cell 10 is connected to an hydraulic motor 30 for driving the winch, this motor and the associated control valve 24 constituting an hydraulic transmission substantially as in Specification 777,230 (see Group XXIX), in which the position of the plunger 28 governs which one or more of the three motor cells A, B, C are in communication with the pump pressure. In particular there is a stop position (in which these cells are all bypassed) and a full haulage position (in which the pump pressure is fed to just one of the motor cells). The second pump cell 11, through a rotary valve 35 may supply fluid either to chamber 25, so connecting the two pump cells in parallel, or to chamber 26. In the latter case, the fluid from the second pump cell is connected to the main control valve 24 in a position such that with the latter's own plunger in its stop position the fluid from the second pump cell is fed to all three cells of the motor in parallel. This condition, with only one pump cell feeding all three motor cells, is used for mooring. If, during mooring, it is desired to haul in the line rapidly, the handle 29 of valve 24 can be operated to allow fluid from the first pump cell to augment the fluid from the second pump cell and also isolate two of the motor cells, thus increasing the tension six fold, but allowing for an immediate return to the mooring setting as soon as the required movement of the load has been effected. For continuous haulage the valve 35 is set to the position in which the two pump cells are in parallel, by rotation of the handle 41. The same handle operates a valve 37 which is more fully described in Specification 918,102 (see Group XXIX), and which governs the pressure in chamber 25, this pressure increasing with further rotation of the handle. Specifications 777,231, 887,194 and 895,102 also are referred to.
