Title: Improvements in or relating to Hoisting Blocks
Inventor: GILS ADRIANUS WILHELMUS VAN
IPC: B66C13/02
Filed: 1967-02-02
Abstract: 1,153,804. Hoisting blocks. A. W. VAN GILS, and W. J. G. STROLENBERG. 2 Feb., 1967 [2 Feb., 1966], No. 5154/67. Heading B8B. A hoisting block for use in moving a load from or on to a ship subjected to wave motion comprises a freely rotatable drum 15 to which a load cable 18 is secured, a winch 27 by which a constant torque is exerted on the drum 15 via an operating cable 20, in a direction to wind up the load cable 18, and a pawl arrangement 9 by which the drum 15 can be arrested. The block is suspended from a crane arm 1 by one or more hoisting cables 3. The latter pass around pulleys 7 in the block and have their ends attached at 10<SP>11</SP> to a pair of spaced plates 8 spring biased upwardly and slidable along guides 12 mounted on side plates 4 of the block. The load and operating cables 18, 20 are wound on opposite ends of the drum 15, such that pay out of the cable 18 causes winding on of the cable 20. The amount of cable 18 payed out is therefore indicated at 32 by the movement of the cable 20, the constant tension in the cable 20 being sufficient only to lift the unloaded hook 19 on the cable 18. In operation, the block is lowered by cables 3 for a load on the moving ship to engage the hook 19, the cables 18, 20 being kept taut by the winch 27 during rise and fall of the load with the ship. At maximum rise, the winch 27 is braked and with the cable 20 causing a pivoted cranked lever 33 around which it passes, to move the plates 8 down until pawls 9 thereon engage ratchet wheels 17 in the drum 15, the load is arrested. The block is then raised by cables 3, which due to their attachment to the plates 8, hold the same in their downward position to maintain the pawl engagement. As the block is raised therefore, the brake on the winch 27 can be released and slack in the cable 20 is taken up. When the load is set down, the load in the cables 3 is released and the pawls 9 move out of ratchet engagement by means of the spring 14, whereupon the drum 15 is free to rotate again. The pawl and ratchet engagement may be effected directly by a manual pull on a cable 40 attached to the lever 33. In the embodiment of Figs. 3, 4 (not shown) the sliding pawl plates are replaced by rotatable pawl plates.

Title: Filter apparatus
IPC: B01D29/00
Filed: 1961-02-13
Abstract: 917,182. Control of several motors. HIRS, G. Feb. 13, 1961 [June 20, 1960], No. 5260/61. Drawings to Specification. Class 38 (3). [Also in Group I] In an apparatus including a tank which houses several filter elements connected to a manifold, and is provided with a conveyer for removing sludge which settles after being scraped from the elements (see Group I), liquid to be filtered is supplied by a motor-driven pump and filtrate is pumped from the manifold. On clogging of the filter elements, the resulting pressure drop in the manifold causes a bellowsoperated switch to close, thereby initiating automatically a cleaning cycle. First the inlet and outlet pump motors are stopped, and a solenoidoperated drain valve is opened to permit the liquid to return to the vessel from which it was pumped. After a pre-set interval governed by a timer, the conveyer motor is switched on and, simultaneously, a solenoid-operated valve is energized to admit air to a cylinder-and-piston assembly which operates the filter-element scrapers. After a further pre-set interval governed by a second timer the air-cylinder valve is de-energized to permit return of the scrapers to normal position. After a further pre-set interval governed by a third timer, the conveyer motor is stopped and the remaining parts of the circuit are restored to normal condition so that filtration re-commences.

Abstract: 238,928. Pehrson, A. H., and Pehrson, A. P. March 5, 1924. Rotary furnaces; air and gases, supplying.-In a continuously working rotary furnace of the kind provided with necks at the ends and with means for distributing and controlling the supply of aeriform or gaseous fluid to the interior of the furnace, such, for instance, as that described in Specification 184,810, the passage of the fluid into the charge is effected through slots, perforations, or other openings in longitudinal conduits disposed at, near or in the furnace walls, and means are provided to prevent the charge from entering the slots &c. As shown in Fig. 1, the fluid-supply pipes 16 are so rotated axially by gears 17, 18 that the lateral perforations with which they are provided are always directed downwardly. In modifications the pipes are not given any axial rotation, but the openings 16<xx>, Fig. 4, are provided with lips 16<x>, or the conduits may comprise a short element 16<0>, Fig. 6, extending inwardly from the furnace wall, and a second element 16<00> inclined as shown. Preferably in all cases the conduits lie nearer the axis of the furnace at the charging than at the discharging end. In the form shown in Fig. 1, the fluid is admitted to the pipes 16 from the supply pipe 8 through an arcuate opening 11 in a conical member 10, openings 13 in the wall of a casing 12 which rotates with the furnace, ,and pipes 14, so that the members 16 are supplied with fluid only when they are covered by the charge, whilst the gases exhaust from the furnace through a stationary casing 15. The furnace shown in Figs. 5 and 6 comprises two chambers 101, 102 separated by a partition 21, so that a charge may first be treated with one fluid in the chamber 101, and after its automatic transference to the chamber 102 through a spiral conduit 22, may be treated with a second fluid. In this form, fluid is supplied to the conduits of each chamber separately from the chambers 9 through arcuate ports 11 in an annular flange 10, openings 12 in the end walls of the furnace and pipes 14. Each chamber 9 may now comprise a lower and an upper section, the former serving to supply fluid to the conduits covered by the charge, whilst the latter serves to draw off the gases from the furnace through a pipe 19, the normal outlet pipe being then closed. The fluid used for treating the charge in the chamber 101 preferably consists of the hot flue gases from the grate employed to heat the gases used for treating the charge in the chamber 102. The material passing off by the outlet 7 may enter a rotary cooling chamber through which cool gases are passed, the gases being afterwards superheated and used to treat the charge.
