Abstract: 141,484. Barnard, D. J. March 24, 1919. Grab-buckets.-In a single-chain grab of the kind in which the spreader arms 8 are pivoted to two top cross-bars 6, 7, telescopic devices are provided to connect the crossbars, the power or pulley shaft, and the cross-beam 5 to which the bucket-halves are pivoted at 3, 4. The telescopic devices comprise rods 28 suspended from the top cross-bars and sliding in tubes 26 carried by the cross-beam 5. The top pulleys 12 are carried by plates 9 fixed to the cross-bars, and the bottom or movable pulleys 14 are carried by plates 18 to which are fixed sleeves 28 sliding over the telescopic members 23, 26. The gravity catches 22 are pivoted at 21 on the plates 18 and engage pins 36 fixed to the cross-beam 5 to hold the buckets closed. The catches are tripped to release the buckets when a lever 37 engages over the edge of a trip-ring 39 suspended from a centralizing-member 42, the lever 37 actuating a sliding arm 43 which operates the catches 22. The grab-rope 47 passes through a two-part centralizing- socket 50 mounted on the cross-bars 6, 7. One spreader arm 8 on each side is extended beyond its pivot, as at 31, and is connected to the other arm on that side by a link 33. Specification 10153/15 is referred to.

Title: Improvements relating to electrical discharge apparatus
Inventor: CHICK DOUGLAS RICHARD
IPC: H05H1/02
Filed: 1959-03-04
Abstract: 931,912. Thermonuclear apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 1, 1960 [March 4, 1959], No. 7608/59. Class 39 (4). A toroidal container for a gas-discharge apparatus has a liner provided with a plurality of apertures defining zig-zag current paths around its large circumference, each of which paths has a resistance which is high relative to that of the discharge but so arranged that resultant current flow round the small circumference is negligible. In one arrangement, Fig. 1, the liner is provided with rows of slots which are staggered to provide zig-zag current paths which are shown dotted. In another arrangement, Fig. 2, the slots are V-shaped. In a modification, Fig. 3 (not shown), the width of the slots varies, being greatest at the apices of the V's. In a further modification, Fig. 4 (not shown), there are two liners as in Fig. 2, one inside the other, and the slots in the two liners are staggered with respect to each other. The use of two liners reduces bombardment of the outer wall by X-rays and charged particles emanating from the discharge. The provision of slots enables the resistance of the liner to be increased by a factor of 50. Specification 830,252 is referred to.

Plate apparatus.-A heat-exchanger, more particularly for heating and/or cooling milk, beer, &c., and of the kind in which passages for liquid are formed by plates provided with facial grooves or ribs arranged to furnish a sinuous course for the liquids is provided with joints of resilient packing, and the admission and exhaust ports are arranged so as to prevent leakage from one part of the apparatus to another while the plates can be easily taken away and cleaned. Packing cord a<4> is arranged in grooves in the periphery of the ribbed plates a, Fig. 1, and is compressed as the plates are tightened together. Passages c in the lugs c<1> are connected by union joints d to headers b. The header channel b<x>, Fig. 2, is formed in lugs c<x> on the plates, a secondary joint comprising a resilient ring e with an inwardly projecting flange e<1>. The plates a<x> are ribbed on each face and are separated by a metal sheet a<0>, a space a<00> being left to allow the escape of liquid leaking past the joints. Figs. 17 and 20 show a plate structure having inlet and outlet passages 8, 8<1> for one liquid outside the main joint a<4>, and inlet and outlet passages 4, 4<1> for the other liquid within the main joint. A groove a<7> is provided for carrying away leakage. The plates are supported by lugs g on a frame which has means for forcing the plates together. The plates may be formed with internal sinuous channels 9, Fig. 20, with or without ribs on the faces to form alternate channels 5. As shown, the liquids flow through the plates in parallel, but removable plugs may be placed at intervals in the passages 8, 8<1>, and/or 4, 4<1>, so that the liquids flow through the plates in series. Plates of heat-insulating material are interposed when more than one operation is carried out in the same plate structure. The positions of the inlet and outlet passages may be varied.
