Abstract: 847,378. Travelling jib cranes. SCOTT & CO. (ELECTRICAL ENGINEERS) Ltd. Aug. 7, 1957 [May 7,1956], No. 14055/56. Class 78 (4). A guard system for preventing the jibs of two or more travelling cranes from getting dangerously close comprises guard models each of which rotates in accordance with the rotattion of a corresponding jib, while at least one can move towards and away from the others in accordance with the relative movement of the cranes. The models generate a warning signal when they contact one another. As shown, metal templates A, B surround models 6a, 6b representing plan views of the slewing jibs of two travelling cranes using the same set of rails. The templates and models are fixed to shafts 5a, 5b and are made by known electronic means to follow the slewing movements of the jibs. The shafts are mounted on carriages 7, 17, of which the latter is fixed and the former is made, also by known electronic means, to move along a track 8 so that the distance between the jib models gives a scale representation 'of the distance between the jibs. Contact of the templates A, B generates a warning signal and may also cut off the power.to the cranes: The templates may be resiliently mounted to allow for movement of the models during braking. The indicating and warning apparatus is repeated and is mounted in the driver's cab of each crane. The system may be extended to jibs which luff.

Abstract: 475,517. Television. BAIRD TELEVISION, Ltd., and JONES, V. May 21, 1936, No. 14400. Drawings to Specification. [Classes 39 (i) and 40 (iii)] In a television relay system, a received signal produces a transient image which is scanned at a different speed to produce an image signal. A transient image is defined as one not requiring any positive operation, distinct from the cessation of the reproducing signals, for its disappearance. The scanning for retransmission is preferably faster than the original scanning. The transient image may be formed by a bank of lamps or on a phosphorescent, fluorescent or incandescent screen or on a storage electrode as disclosed in Specification 475,047 to obtain a high persistency, so that it may, for example, be reconstituted at the low rate of four pictures per second. Where the transient image is projected onto the cathode of an electron camera for scanning, the screen may be mounted within the electron camera close to the cathode. Specifications 437,021 and 471,539 also are referred to.

Filed: 1946-05-14
Abstract: 611,950. Actuation of switches. SEGRAVE, C. R., WILLIAMS, T. B. GLYNNE-, and BARKER, H. H. May 14, 1946, No. 14506. [Class 38 (v)] A fluid-pressure actuated switch comprises a spring-pressed plunger, Fig. 1 (not shown), bearing on a diaphragm 3 and on a bridge-piece 9 carrying spring-loaded contacts 10, 12 cooperating with adjustable fixed contacts 11, 13. On an increase in pressure, the bridge 9 moves upwards and, first contacts 10, 11 close and then, if the increase is maintained, contacts 12, 13 close. The former prepare the circuit of a relay coil 21, which is energized when contacts 12, 13 close, thereby closing contacts 22 to energize a control unit 23. If the pressure now drops, contacts 12, 13 reopen, but, owing to a shunt connection 24, the coil 21 remains energized until contacts 10, 11 open. The coil is therefore de-energized at a lower pressure than that at which it is energized. The diaphragm may be exposed to the intake duct or the liquid-fuel pipe of a liquid-fuel heating system of an aircraft so as to cut out the control unit 23 if the aircraft is grounded or the pipe breaks. The diaphragm may be replaced by a piston or a coiled tube.

Title: Improvements in and relating to the stabilisation of petroleum products
IPC: C10L1/18
Filed: 1933-05-26
Abstract: Petroleum oils e.g., gasoline and transformer and turbine oils, are rendered fluorescent and are stabilized against discoloration and gum formation by adding binaphthylene oxide and/or dioxide; when gasoline contains colouring material and/or organo-metallic compounds such as tetraethyl lead it is stabilized by perylene, binaphthylene oxide, binaphthylene dioxide, or mixtures thereof. 0,25--3,0 lb. of stabilizer per 10,000 gallons of gasolene is satisfactory. Tetraethyl fluid, i.e., lead tetraethyl with customary modifying agents such as ethylene dibromide and monochlor-naphthalene, for addition to gasoline may itself be stabilized by 0,01--1,0 per cent of the above stabilizers.  In an example, 10,000 gallons of gasoline are coloured and stabilized by 0,25 lb. of 1,4 diparatoluido-anthraquinone and 2,0 lb. of binaphthylene oxide. Other colours specified are monomethyl-amido-paratoluido-anthraquinone and 1-hydroxy-4 paratoluido-anthraquinone.
