A load pulley block mounted in a bight of the cable 40 between the drum and a support hook 37 located on a part 12 of the housing, is raised by anti-clockwise movement of the lever 14 whereupon the operating pawl 26 causes rotation of the drum through a ratchet wheel 18 integral therewith, the holding pawl 25 locking the wheel 18 as the lever 14 is retained for another operating stroke. During the above operation the control lever cam 32 is set as shown and the finger 34 of the reversing ring 22 is spring biased into engagement therewith. For lowering the block, the cam 32 is set into a vertical position whereupon the finger 34 moves anti-clockwise under the force of a spring 24 causing the finger 35 to lift the holding pawl 25 out of engagement with the ratchet wheel 18, With clockwise movement of the handle 14 therefor, the cable 40 is unwound until the reversing ring is turned clockwise due to engagement between the pawl 26 and finger 36 to allow re-engagement of the pawl 25 and wheel 18. With anti-clockwise movement of the lever 14, the pawl 26 is not disengaged from the finger 36 until the finger 35 re-engages the pawl 25 and spring biased rotation of the ring 22 is prevented. A free wheeling of the drum for paying out unloaded cable may be effected by disengaging the pawl 26 from the ratchet wheel 18 either directly or by depression of a quick lowering button on the handle 14, while the pawl 25 is held disengaged by the reversing ring finger 35. A rapid winding in of the unloaded cable may be effected by a crank handle on the drum. A spring steel guard 41 passing over the drum 15 guides the cable thereonto after passing through a cable guide ring 42. In the embodiment of Fig. 11 (not shown), a load carrying web is used and is looped at one end to be pinned into a slot formed in the drum hub.

Filed: 1918-02-07
Abstract: 120,678. British Insulated & Helsby Cables, Ltd., and Wilson, L. B. Feb. 7, 1918. Fusible cut-outs.-Relates to cut-outs and connecting links in which the detachable hand-grip part carries self-adjusting contacts for engagement with clip contacts, and consists in forming the self-alining contacts of thin high-conductivity metal, for example rolled copper, bent or stamped to a box or tubular form and made rigid by one or more corrugations which may serve to hold the contact in a loose, self-adjusting manner on the handle. In the form shown in Figs. 1 and 2, the thin metal strip bent into box form is held loosely on the end 3 of the handle portion by tongues cut 14 out of one end of the strip passing through holes in the other end. An inwardly-extending corrugation 10 passes round the contact and engages loosely with a groove round the end of the handle part. Instead of the ends of the box-stamping being connected together they may be inwardly bent and spaced apart so as to receive between them a plate spring tending to expand the contact and ensuring a good contact pressure with the clip contact. Means such as pins may be used to hold the contact adjustably in position instead of the corrugation which then serves for strengthening purposes only.

Abstract: 1,198,807. Calcium sulphate α-hemihydrate. IMPERIAL CHEMICAL INDUSTRIES Ltd. 4 Jan., 1968 [17 Jan., 1967], No. 2475/67. Addition to 1,051,849. Heading C1A. In a continuous process for the production of calcium sulphate α-hemihydrate slurry from gypsum by heating gypsum slurry to 130C- 170 C., under a pressure greater than that required to maintain water in the liquid phase at the reaction temperature, (as in 1,051,849), the rate of reaction may be controlled and accelerated by injecting high pressure steam. The steam forms "hot" zones around the steam injection ports, and within the "hot" zones the temperature is 10C-15 C. higher than the temperature of the bulk of the slurry. Within these "hot" zones crystal nuclei of calcium sulphate α-hemi-hydrate are formed rapidly and if these are stirred into the bulk of the slurry the overall reaction is accelerated. The size of the hot zones may be controlled by controlling the temperature, pressure, velocity and volume of the injected steam, and by varying the size(s), shape(s), position(s) and number of the steam injection port(s). By varying the rate of agitation of the slurry and the aforementioned factors, it is possible to control the number of calcium sulphate α-hemihydrate crystal nuclei in the bulk of the slurry, and thus possible to control the rate of reaction and the physical properties of the α-hemihydrate slurry formed.
