Title: Improvements in or relating to discharging hopper wagons, hoist boxes, tipping buckets and the like apparatus
IPC: B65D88/56
Filed: 1926-07-05
Abstract: 283,231. White, J. W. July 5, 1926. Tip-buckets; tip-boxes. - The tipping body 1 is mounted on pivots interconnected with a hanger 13 or supporting frame so that on release of a catch 8 the weight of the body 1 causes its rotation through 180‹ and a vertical or substantially vertical drop relative to the hanger or frame. The device is intended for use with sticky materials, and air holes may be provided in the bottom of the bucket to facilitate discharge. The invention is shown as applied to a tip-bucket for use on aerial ropeways. In Fig. 1, the bucket is pivoted at 2 in arms 3 which are pivoted at 4 in the hanger 13, the pivot 4 being below the centre of gravity of the full bucket. The bucket turns about the pivots 2 and 4 when released by the catch 8. Stops 6, 7 on the bucket come in contact with the arm 3. In the form shown in Fig. 3, the trunnions 12 which rest on the hanger are carried on plates 13a which are free to slide in slotted guides 11 on the bucket so that on tipping, the bucket drops relatively to the trunnions 12. In the form shown in Fig, 6, a pinion 18 secured to the bucket engages a rack 17 on the hanger, but is restrained from running down the rack by the catch 8 which prevents tipping. On release, the bucket falls until the pinion is checked at the bottom of the guide 16, and the rack ensures rapid tipping. In this form, the bucket need not be pivoted above its centre of gravity and is self-righting, balance weights being used if desired.

Title: Improvements in or relating to failure alarm arrangements for electric signal amplifiers
IPC: H04M9/00
Filed: 1947-06-30
Abstract: 635,845. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and THOMAS, P. R. June 30, 1947, No. 17171. [Class 40 (vi)] [Also in Group XXXIX] In an alarm circuit for indicating the failure of one of a pair of amplifiers operated in parallel, part of the output of each amplifier is rectified and the resulting voltages are applied in opposite senses to the grid of a valve having an alarm relay in its anode circuit so that the relay operates when the difference in the rectified voltages exceeds a specified value. The outputs of two amplifiers are applied through a hybrid transformer to supply a common load (Fig. 1, not shown). Part of the output of one amplifier is applied to transformer 10 and part of the output of the other to transformer 11. The transformer secondaries are connected to oppositely directed rectifiers 12 and 13 to produce a voltage across smoothing condenser 17 depending on the difference of the input voltages. The anode circuit is arranged as a D.C. bridge with an unpolarised alarm relay 23 connected across one diagonal. When a fault occurs, the input voltages become unequal and the bridge is unbalanced causing the relay to operate. If the relay is polarized and has a centre stable armature, different alarms may be operated depending on which amplifier fails.

Abstract: 458,371. Obtaining rare gases. I. G. FARBENINDUSTRIE AKT.-GES., Frankforton-Main, Germany. June 17, 1935, No. 17396. Convention date, June 16, 1934. [Class 8 (ii)] To obtain krypton &c., oxygen produced by the rectification of liquid air is evaporated in a narrow elongated still, such as a coil, and the vapours are returned to the same or a second rectifying column. Oxygen accumulating in the base of the rectifying column 1, trickles down a narrow still 4 tapering towards the bottom and is heated by compressed air passing through a tube 5 therein. Oxygen vapour rises and liquid enriched in less volatile constituents falls into a separator 7 from which liquid is drawn off through a valve 8 while vapour is drawn off through a valve 23 and some vapour may be returned to the column 1 through pipe 9. After a time the valves 10 and 11 are closed and the oxygen from the column 1 delivered to a still 14 in the first part of which the liquid and vapours flow in counter current and in the second, upturned, part flow together to a separator 17. The still is heated by compressed air diverted from coil 4 by the valve 15 ; the air is thus liquefied in the stills, and is delivered to the colum 1 through a valved pipe 2. Part of the gas escaping from the rectifier 1 is delivered through a pipe 21 and valve 22 to that one of the stills not in use to free it from accumulated hydrocarbon &c. impurities. In a modification, oxygen from a fractionating apparatus is delivered to a rectifying column in the base of which it is partly evaporated by a compressed nitrogen coil, the residual liquid flowing on to a coil surrounded by the nitrogen from the heating coil, and into a separator from which vapours pass back in part to the first rectifier and in part to a second rectifier, the top of which is cooled by evaporation of nitrogen from the heating coil of the first rectifier. The second rectifier is heated at the base by compressed air afterwards delivered to the interior of the rectifier.
