Filed: 1919-03-06
Abstract: 143,336. Armstrong, Whitworth, & Co., Sir W. G., Lee, H. W., and Swindale, J. W. March 6, 1919. Loading-appliances.-Relates to hoists, particularly for projectiles, in which a step-by-step lift is derived from spring-controlled lifting-pawls hinged to a vertically reciprocating slider coacting with spring retaining-pawls hinged at fixed intervals to the wall of the hoist trunk. According to the invention, the pawls are positively moved out of the path of the projectiles. In the form shown in Fig. 1, a continuously rotating shaft 1 operates the vertically reciprocating slider 18 and the lifting-pawls 29 hinged thereto through connecting-rods 17, 25 respectively, both actuated by a crank 15 and worm-drive 3, 2, 1. The shaft 1 also operates the retaining-pawls 13 by a connecting-rod 9 actuated by a cam 7 on the worm-wheel 3. The lifting-pawls 29 are hinged to vertical extensions of the slider 18, and are connected by links 28 to a lever arm 26 which is pivoted to a bracket 27 on the slider and connected as described below to the crank 15 by the rod 25. The rod 25 is engaged by a pin 24 with a cam-groove 23 in a disk 22 fixed to the crank-pin 16. The connecting-rods, pawls, &c. are arranged in pairs. Two sets of lifting-pawls acting alternately may be employed. Projectiles enter the hoist at 35 when a spring-supported door 32 is lowered, and leave automatically on reaching the top of the hoist by falling against a weighted suspended door 36.

Filed: 1942-04-30
Abstract: 557,215. Hydraulic tele-control apparatus. AMERY, G. April 30, 1942, No. 5853. [Class 69 (ii)] [Also in Group XXIV] In hydraulic tele-control apparatus wherein automatic means lock the actuated member in position when movement ceases, and the liquid in the transmitting line is also then brought into free communication with a storage receptacle, the receiver piston is locked by pistons on the actuated member, exposed to liquid in two locking chambers movement of liquid from which is prevented by a valve opened only by an actuating force applied to the liquid in the operating cylinder of the receiver piston. The tele-control receiver piston 16, Fig. 2, is connected to the actuated member 17 by a rod 19 carrying a locking piston 20 and passing through a wall 21, a liquid reservoir 25 surrounding the locking cylinder 23. The locking valve 27 in the rod 19 is actuated by fluid pressure either directly or through a diaphragm 50 the upper side of which is subject to the atmospheric reservoir pressure through ports 52, 53. The valve 27 controls passages 29, 30, 31 by which the locking space 36 and the space 44 in position 20 above the end of rod 19 are opened and closed to atmosphere. A second locking valve 34 controls passages 39 connecting the spaces 42, 36 above and below the piston 20, and is opened by upward movement of the rod 19 acting on its stem, or by suction in chamber 42 when, the piston 16 being under suction, the valve 27 opens the space 36 to atmosphere. The transmitting piston 12, Fig. 1, is connected by a rod 60 passing through a partition 61 with a locking piston 62 in a cylinder surrounded by an atmospheric reservoir 65. The actuating member 11 passes slidingly through the locking piston and rod to a valve chamber wherein it is connected to a doubleheaded valve 67. of cruciform section normally held open by springs to allow communication of the transmission line with the reservoir through ports 72, 74. A locking valve 77 is pressed upward by a spring to seal passages 82 through the locking piston, and a port 84 connects the valve chamber to the space 85 below the locking piston. A non-return valve 86 allows liquid to pass from the reservoir to the space 85, and an outlet locking valve 87 allows liquid to pass from the cylinder space 83 to the reservoir. The valve 27 may be provided with a latch released hydraulically. In a modification the space 73 is connected not to the reservoir but through a second transmission line to the space 42 at the head of the receiving cylinder, which is not provided with a reservoir.

Title: Process for treatment of dolomite and high-calcic limestones
IPC: C01B17/42
Filed: 1945-03-12
Abstract: A process for the treatment of dolomites or high-calcic limestones comprises calcining the rock to its constituent oxides of magnesium (if present) and calcium, for example, according to the process of Specification 538,135, suspending the calcine in an aqueous solution of ammonium polysulphide boiling the suspension in a closed system until the ammonia is completely liberated, filtering and concentrating the solution of calcium pentasulphide, and, if magnesium is present, gently calcining the filtered magnesic residue. Preferably, the calcine is suspended in the polysulphide solution in the proportion of one part calcine to twelve to fifteen parts solution (in the case of dolomites) or to twenty to thirty parts solution (in the case of limestone), and the suspension is boiled for less than forty-five minutes by a current of steam.  The filtrate may be evaporated to give solid calcium pentasulphide, or may be treated with hydrochloric acid to give sulphur hydrogen sulphide, and calcium chloride solution, which latter may be further treated by injecting carbon dioxide and ammonia to give calcium carbonate and ammonium chloride.  The magnesic residue, consisting chiefly of magnesium hydroxide, may be lightly calcined to give magnesia of high purity. Specification 556,670 also is referred to.

Abstract: 583,522. Bottling. MANNING, A. J. April 4 1944, No. 6277. [Class 125 (ii)] [Also in Group XXX] Transfer mechanism (see also Group XXX) for a machine for filling and sealing or otherwise processing ampoules and like containers, comprises a stationary support having means for supporting a number of containers spaced from one another and locating them at the respective processing stations ; a movable carrier which, in timed relation to the other processing operations, picks up the containers and transfers them from one station to another; and means positively retaining the containers on the carrier during the transfer operation. Ampoules 6 rest at their respective stations (e.g., during filling and sealing, at the filling and sealing stations) in recesses 12 formed in stationary supporting bars 4. The ampoules are transferred from a magazine 5 to a processing station, from one station to another, and finally to a discharge tray 7, by a pair of parallel bars 15 having recesses 16 to receive the ampoules. For this purpose, the bars 15, which are supported by toggles 21 on carriages 19 fixed to slidable rod 18, are given a rectilinear reciprocation, and are also raised to pick up ampoules at the beginning of the left to right stroke (as seen in Fig. 2) and lowered, when they reach the end of this stroke, to deposit the ampoules. The reciprocation is effected by an electric motor, through gearing, a cam and linkwork, and a bell crank lever 52 and connecting rod 55, which act against a return spring 57. At the left-hand and right-hand ends of the stroke, the toggles 21 are respectively straightened and collapsed, to raise and lower the bars 15, by impact with stop screws 26. A bar 65, also provided with ampoule-locating recesses 66, is supported by one end of each of two levers 61 pivoted centrally to plates 63 secured to the carriages 19. The levers 61 have pin and slot connections 60 with the upper ends of links 58 which rise and fall with the bars 15.
