Filed: 1941-10-15
Abstract: 552,652. Valves. LUCAS, Ltd., J., and SPENCER, G. D. Oct. 15, 1941, Nos. 13276/41 and 1435/42. [Class 135] [Also in Groups XXXVI and XVII] A filling-device for an electric storage battery, of the kind adapted to determine automatically the level to which the liquid is filled, comprises a cup formed with or adapted to be secured to the upper part of the battery casing and an axially movable or rotatable hollow valve which when open allows liquid to pass into the battery from the cup and also closes an air escape-vent, so as to prevent the liquid rising beyond a predetermined level, the air vent bemg opened when the valve is closed. As shown in Fig. 8, the device comprises a body portion b adapted to be screwed into the battery casing and formed at the upper end as a cup d. A hollow valve member h is slidably mounted in the body, so that when it is raised to the position shown liquid poured into the cup d passes through apertures p in the valve wall to its hollow interior and thence to the cell. When the valve is lowered, the apertures p are closed and vent apertures m, f respectively in the body and the valve coincide so that gases may escape through the valve and through further vent apertures n in it. In the raised position of the valve, the apertures f are closed so that an air lock is formed which prevents filling of the cell above the level of the bottom of the body portion b. A cover z pivoted to the top of the valve holds the latter in the raised position by resting on the cup. and when the valve is lowered closes the cup. Fig. 9 shows a device having a rotary valve h which is operated by the rotary movements given to it in removing and replacing a cap z having a bayonet-joint engagement with the cup d and a groove 10 engaged by a transverse projection on the head of the valve. In the position shown, the openings p for the passage of fluid are closed and the vent openings # are uncovered. On removing the cap, the valve is rotated to close the openings f and cause the openings p to coincide with grooves u in the body. Similar forms to both of the above in which however no covers are provided, and also a form in which the valve is threaded into the body so that it is moved between upper and lower positions by rotating it, are also described.

Title: Improvements in or relating to screw presses
IPC: B30B1/18
Filed: 1927-05-19
Abstract: 297,352. Walker, M. May 19, 1927. Presses, mechanical.-In screw presses, such as baling presses, of the kind operated by worm gearing, the usual fast and loose belt pulleys on the driving- shaft are replaced by a pair of electromagnetically - actuated friction clutches. In the illustrated form the main shaft 11 drives the screwed spindle 6 carrying the platen through worm gearing 5. One electromagnetic clutch 12 connects the shaft 11 to the power shaft to advance the platen for pressing, while the other 13 connects the shaft for retracting the platen. A solenoid 17, Fig. 2, shunted across the motor circuit, raises the lever 24 when the press is exerting. a predetermined pressure and breaks the circuit through the driving clutch 12 by removing contact rods from the mercury cups 28. A spring trip lever 32 holds the parts in this position. When the main circuit through the clutch 12 is broken, as for example by connecting up the reversing clutch 13, the lever apparatus 24 is ready to restore the circuit at 28 immediately the trip lever is drawn back by hand. The predetermined pressure at which the solenoid operates may be varied by adjusting the initial position of the movable core 18 by means of the disc 21. Reference is made also to the working of the reversing clutch 13 automatically with a timelag after the completion of pressing by means of clockwork-mechanism, and to the automatic cutting-out of the reversing clutch when the platen has been retracted to its initial position.

Abstract: 787,272. Filling containers. PNEUMATIC SCALE CORPORATION, Ltd. May 11, 1955 No. 13676/55. Class 94(1)1 [Also in Groups XVIII and XXIX] A container filling machine forms loads of granular material in chambers for discharge into containers, the volume of the chambers being automatically adjustable in accordance with a check weighing taken directly from the source of supply to the chambers. The chambers 14 depend from the base plate 18 of a hopper 10 and the hopper and chambers, funnels and carton conveying means are as described in Specification 791,058. The check weighing sample is taken directly from the supply tube 12 and in one embodiment, it flows into a vessel 71 which is periodically moved horizontally to discharge its contents into the weighing receptacle 68. The weighing apparatus (see Group XVIII) is substantially the same as in Specification 791,058 but in this case the receptacle carries a member 142 in the path of an air jet 136. The deflection of the receptacle under load determines the degree of obstruction of the jet by the member 142 and this causes a switch member 162 attached to a piston 166 to contact one or other of contacts 192, 194, Fig. 9, according to whether the load is light or heavy. This activates one or other of solenoids, Fig. 4 (not shown), to permit ratchet and pawl mechanisms 212 or 213 to turn a shaft 210 connected to one of the volume adjusting screws 200 which operate as described in the abovementioned Specification and in Specification 707,748. After the check weighing, a lever 270 is acted on by cam means to open shutters 254, 256 and discharge the sample into the hopper. In another embodiment. Fig. 12, material flows continuously into and out of a weighing receptacle 402. An element 420 on the receptacle is in the path of twin opposed jets 412, the obstruction of one or the other causing adjustment of the volume as previously described. Means for settling the material in the packets forming a feature of the machine of Specification 791,058 is not described in connection with the present machine. U.S.A. Specification 1,527,030 also is referred to.
