Title: Safety devices for jib cranes of variable working radius
IPC: B66C23/90
Filed: 1971-04-07
Abstract: 1400402 Crane safety devices STRAWSON HYDRAULICS (CONSULTANTS) Ltd and WHARNCLIFFE FABRICATORS & ENGS Ltd 4 July 1972 [7 April 1971 6 Oct 1971] 8993/71 and 46480/71 Heading B8B A safety device for a jib crane (16), Fig. 1 (not shown), of variable working radius utilizes a plurality of printed circuit boards 122, used selectively, to relate the load to the maximum allowable safe working load at a particular work-  ing radius and under particular working conditions. A mercury switch (44), Fig. 2 (not shown), used in conjuction with a servomotor (48) produces an electrical signal corresponding to the elevation of the jib, while a spring-loaded, jib-length, cable drum (52), Fig. 3 (not shown), ultilizes an electrical proportioning device to produce an electrical signal corresponding to the jib length. These two electrical signals are compounded to produce a further electrical signal corresponding to the working radius of the crane. The printed circuit board 122 comprises a non-conductive lamina 124 with conductors 126, 128 extending in parallel along its upper and lower edges. A metallic line 130 is also presented just proud of the lamina 124 and represents the safe load/radius curve (for a particular working condition) supplied by the crane manufacturer. A resistance element is associated with the circuit board 122 and comprises an insulation rod 132 with several thousand turns of resistance wire 134 and bonded to a supporting strip of insulation material 136. In use a voltage is applied across the conductors 126, 128 and the resistance element is caused to move, in contact with the conductors 126, 128 and the wire 130, across the board 122 in response to the changes in working radius of the crane. The device acts as a potential divider and its output signal is dependent on the curve of the line 130 and can be compared with the actual load on the crane as measured by an electronic load cell (60), Fig. 4 (not shown), acting against the load rope (32). The result of comparing the signals may be used to activate a visual alarm, followed by an audible warning, when the safe working load is approached or exceeded, when a recorder may be brought into action. Instead of resistive devices the safety device may utilize inductive or electrostatic devices, Figs. 8 to 10 (not shown).

Abstract: 870,174. Game apparatus. BRENNER Ltd., B. W. March 29, 1960 [March 17, 1959], No. 9283/59. Drawings to . Specification. Class 132(2). In "Bingo" &c. apparatus in which each player has a board having an array of numbered areas illuminated separately by lamps, selection of a number by a central scoring device controls relays associated with the lamps and completion of any line on a player's board stops the operation of the apparatus. The scoring device comprises, inter alia, an array of pockets each of which contains a pair of contacts closed by entry of a ball. Such an entry causes the illumination of a particular lamp on a central indicating panel. With each indicating lamp is associated a push-button which the operator presses when a number has been scored this resulting in energization of a master relay which operates control relays relating to the scored number so that the appropriate lamps on the players boards are extinguished. When a whole line of lamps has been extinguished, winning. lamps and buzzers are energized and any further entry of balls into pockets is rendered ineffective. The apparatus is made ready for the next game by the discharge of balls from the scoring device. Means are provided for a central free space on each board, for each board a push button allowing the extinguishing of one other lamp, preventing starting of the game unless a quorum of players. is present, and allowing operation of the indicating panel by the operator for display purposes. All the push buttons may be depressed by application of a grid so that a scoring ball energizes directly the relays associated with the players board.

Title: A process for the electrolytic production of manganese compounds
IPC: C01G45/00
Filed: 1938-03-28
Abstract: 498,793. Electrolytic production of manganese compounds. HOCHWALD, F. March 28, 1938, No. 9506. [Class 41] Alkali or alkaline-earth manganates are obtained by electrolyzing anodes containing manganese, such as ferromanganese or silicomanganese anodes, in a concentrated solution of alkali or alkaline-earth hydroxide ; the manganates so obtained may be oxidized to permanganates, if desired after separation and re-solution. Less soluble manganates and permanganates (e.g. potassium) may be made from more soluble manganates and permanganates (e.g. sodium) by double decomposition. Any crystals which separate at the anode may be redissolved in water or dilute alkali, the solution so obtained being used for dissolving manganate deposited in the electrolyte. The electrolysis may be carried out continuously by constantly or periodically adjusting the alkali concentration, and it is advantageous at the beginning to use a higher voltage than subsequently. In examples, solutions containing 35 and 50 per cent potassium hydroxide are electrolyzed using anodes of 80 per cent ferromanganese and nickel cathodes at a few volts, followed by electrolytic oxidation of the manganate obtained. The mother liquor from the permanganate may be evaporated down, treated with more alkali if necessary, and used for the electrolysis.
