Patent GB-536952-A (GB)
Title: Improvements relating to grab cranes
IPC: B66C3/12
Filed: 1939-12-01
Abstract: 536,952. Winches. PRIESTMAN BROS., Ltd., and FRANKLIN, A. E. Dec. 1, 1939, No. 31288. [Class 78 (v)] Winch mechanism for grab cranes of the kind having two drums, one for the hoisting and closing rope of the grab and the other for the opening and holding rope, has means whereby is automatically avoided the disadvantage that when the open grab is being lowered a tendency exists for the hoisting drum to lag behind the opening and holding drum, owing to the difference in diameter of the two gear-wheels, with the result that the pay-out of the closing rope is checked and the grab tends to close. The two drums 10, 12 are geared together through an additional clutch so that the drums have to rotate at the same speed. This clutch 38 is of the relay type, so that it functions only when the grab is being lowered. The gearing comprises two equal pinions 32, 33, of which 32 is fixed to the drum 12 and 33 is connected to the drum 10 through the clutch 38. The hoisting of the grab is effected through the main clutch 22. This causes both drums to turn, the gearing 34, 36 being non-effective because the clutch 38 is disengaged. To open the grab the motor is stopped, the drum 12 is braked, and the main clutch 22 dis-engaged. This frees the drum 10 and allows the grab to open, the drum rotating backward in consequence of the paying out of the hoisting rope. As the wheel 34 is held against rotation at this time, being in mesh with the wheel 36 fixed to the drum 12 which is braked, the clutch 38 does not become engaged although its relay brakeband is tensioned, and the drum 10 can therefore rotate to allow the grab to open. When, however, the drum 12 is released to lower the opened grab both wheels 34, 36 rotate, and the relay brakeband, being already tensioned, prevents the relay drum from rotating and causes the clutch to engage. The drum 10 is thus positively driven by the drum 12 through the wheels 34, 36, effecting equal pay-out of both ropes and preventing closing of the grab during its descent. Specification 264,327, [Class 80 (ii)], is referred to.

Title: Improvements in or relating to change-speed mechanism
IPC: F16H63/46
Filed: 1936-11-17
Abstract: 484,816. Controlling change speed gearing. OLIVER, A. V. Nov. 17, 1936, No. 31408. [Class 80 (ii)] Striking-forks a, controlling synchromesh change-speed gearing of the kind described below, are all loosely mounted on a single rod b, reciprocated by operation of an executive and main-clutch pedal, a selected one of the forks being locked to the rod when in the neutral position, under control of a sliding preselector rod c, carrying selectively-placed spring-loaded pegs i, which, through pellets f, depress spring- loaded plungers d, carried by the forks a (or rod b), freeing them from holes in a fixed locking- plate e and causing them to engage holes in the rod b (or forks a). The change-speed gear (not shown) is of the kind described in Specification 459,556, i.e. in which the striking-forks are moved in one direction (from right to left Fig. 1) on downward movement of the executive pedal, to neutralize the gear and then synchronize the selected speed frictionally, and in the opposite direction on upward movement of the pedal, to engage the dog-clutch of the selected speed. The plunger-receiving holes in the rod b (or forks a) are constituted by a groove in the rod (or forks), receiving sliding ribs h, which form an interlock ensuring that only one plunger at a time can engage the rod b (or forks a). The rod b is loaded in the gearengaged direction by a spring m, and is moved in the opposite direction by a cam k on a shaft l, turned by the executive pedal. A second cam p on the shaft l, disengages the main-clutch through a spring-returned rod o. The cam contours are so arranged that the following sequence takes place on depression of the executive pedal. First the main-clutch is disengaged, after which the rod b is moved to the left, returning to neutral any previously engaged striking-fork a. In this neutral position there is a dwell to allow time for one of the spring- loaded pegs i to depress the plunger a of the preselected fork, locking it to the rod b. The rod b then continues its leftward movement, taking with it the preselected fork, thereby frictionally synchronizing the new speed. The upward return movement of the executive pedal permits the spring m to return the rod b and with it the preselected fork which engages the dog clutch of the speed which it controls. Following this, the main clutch is allowed to engage. In order to reduce the effort required to depress the executive pedal, the shaft l may carry a third cam subjected to the pressure of a spring-loaded roller, the contour of the cam being chosen to produce any desired assistancecharacteristic.

[Class 38 (iv)] Condenser arrangements. -An arrangement for charging rapidly a condenser 7, adapted to supply an X-ray tube 21, comprises a high reactance transformer 1, 2 having a no-load secondary voltage exceeding by at least 30 per cent the operating voltage to which condenser 7 is to be charged and supplying this condenser through a rectifier 5. When the condenser 7 reaches its operating voltage the primary circuit of transformer 1, 2 is broken by a switch 18 operated by the anode current of a gas-filled discharge relay 9 having its grid 12 and cathode 10 connected through a tap 13 across all or part of the winding 2 so that the relay is rendered conducting when 7 reaches its operating voltage. Opening of switch 18 also de-energizes the anode supply transformer 15, 16 and may cause operation of the switch controlling the condenser discharge circuit the switch 18 being reset when desired by hand or remote control. In an alternative arrangement Fig. 2, the transformer secondary 2 may supply the condenser 7 through rectifiers 5, 6, a spark gap or discharge tube 8 being shunted across the charging circuit and being arranged to function when the condenser reaches its operating voltage to reduce or prevent increase of the supply voltage. Instead of using a high reactance transformer an impedance may be placed in the charging circuit to take up the difference of potential between the A.C. source and the condenser, a relay being connected to it to switch off the charging current at the appropriate voltage. The arrangement may be used for cinematographic work.

Title: Improved process and equipment for steelmaking or other refining of iron
IPC: C21C5/56
Filed: 1961-09-01
Abstract: <PICT:0983844/C6-C7/1> Iron, particularly phosphorus-bearing iron, is refined or converted into steel with oxygen in a tandem reactor process by treating a bath of the molten iron in a reactor A by injecting at least part of the oxygen required for refining as a stream 3, e.g. from a lance POL, from one end of the reactor at an acute angle, e.g. between 35 and 50 degrees, to the bath surface and with such high velocity, e.g. 1.2-3 mach, that the stream is finely dispersed within the bath without striking the bottom, the resultant hot gases passing from the reactor A at its other end into a second reactor B to preheat, melt and control the temperature of input material, such as pig iron, scrap, ores, coolants, fluxes and slag formers, charged into the reactor B whilst refining is effected in reactor A. After tapping the refined or converted material in reactor A, the process is reversed by refining or converting the material in reactor B in like manner with oxygen and passing the resultant hot gases into reactor A which is being charged with fresh input material. Additional oxygen or air may be injected, e.g. through auxiliary lance b (or a, in reversed process), into the other reactor to burn CO in the hot effluent gases to CO2 to cause a further increase in the temperature of the input material; for reducing the temperature, steam, nitrogen, argon or other neutral gas may be introduced.  At least one of the reactors may be operated with negative pressure.
