Title: Safety mechanism for prevention of overwinding in hoists and the like
IPC: B66D1/06
Filed: 1944-01-28
Abstract: 574,588. End stop mechanism for hoists. GARNER, W., and PRESTON, P. Jan. 28, 1944, No. 1597. [Class 78 (v)] A friction wheel 3 on the shaft of the winding drum is adapted to be moved between contact with a motor-driven friction wheel 4 and a stationary brake block 5. The drum shaft is carried by one end of a lever 2 journalled in a frame 27 and hooked to a lever 6 operated by a pull cord 14. The lever 6 is hinged at one end to the lever 2, and has a cross-pin 20 which can engage with catch levers 7, 8 pivoted respectively at 18 and 22 to the lever 2. An extension 28 of the drum shaft carries a screw fixedly mounted on which is one member of a toothed clutch and axially movable on which is the other member, the latter being normally prevented from turning by wings sliding on guides 29. When the cord 14 is held pulled for too long a period, so that the load becomes about to over run the drum, the clutch members enter into engagement and the guides 29 are carried bodily round, taking with them a cam 32 against the pull of a weight 31. The cam 32 raises a bell-crank follower 33, and through the arm 34 and a rod 35 turns the catch 7 against a spring 21 to release the pin 20 from a notch 19 in the catch 7 and allow the lever 2 to fall under the pull of a weight 36, so removing the wheels 3 and 4 from contact and applying the brake 5. If the cord 14 is now pulled, the lever 6 will rise and by the pin 20 lift a sliding member 24 on the catch 8 as far as an abutment 25, beyond which further rise of the lever 6 will lift the lever 2 through the catch 8 and allow the drum to reverse under the gravity pull of the load, thus de-clutching and permitting the weight 31 to return the cam 32 and so put the catch 7 once again under control of the spring 21. On making a second downward movement of the lever 6 the catch 7 effects re-coupling to the lever 2 and puts the drum once more under complete control of the cord 14. A stop 26 on the frame 27, or a stop on the cord 14, prevents the levers 2, 6 from being raised to an excessive height.

Abstract: 949,125. Making valve grids. KABUSHIKI KAISHA HITACHI SEISAKUSHU. Jan. 18, 1962, No. 1876/62. Heading B3A. A method of making a grid comprises forming a stack of alternate layers of two different kinds of metals 2, 3 in ribbon form; bending the stack in the plane passing through the longitudinal axes of the metals and simultaneously bonding the said alternate layers to produce a laminated structure cutting circular pieces 4 from the said structure, bonding a support member 5 to the periphery of each circular piece and removing all layers of one of the metals to produce a grid structure. The material which ultimately forms the grid may be tungsten or molybdenum and the interleaving material iron. Fusion-bonding of the stack is achieved by applying to a side surface a material such as copper, copper-nickel, or manganese and heating while the stack is being bent. In addition to the support 5 a holder 6 is welded to each circular piece and the complete assembly is ground to the required thickness before the iron ribbon 3 and holder 6 are etched away by hydrochloric acid. In a modification, the stack is bent transversely (Fig. 8) a cylindrical body (Fig. 9) is cut from the bent laminated material, gold-plated and fitted with a platinum sheath, before being cut into discs of the required thickness and finished by etching.

Electric installations, arrangement of.-In electric distribution systems for ships and other places having separate compartments liable to flooding, each of the compartment feeders is provided with separate disconnecting-means sensitive to the rise of water in the compartment so that if one or more compartments are flooded the corresponding feeders are disconnected leaving the mains intact for use. The feeders a, Fig. 1, have fuses b in their length, the feeders being short-circuited by the switch d, e when flooding occurs. The switch may be held open normally by a fuse wire h, which is blown when the rising water closes the local circuit through the contacts i. A float containing salt water may be used to complete the circuit through the contacts the float being housed in a box having Venturi passages 'acting as water admission and outlet. The shape of the passages prevents flooding by a j et of water accidentally directed on the box. In a modification, part of the compartment feeders are made of a length of carbon tube t, Fig. 6, which is broken by the explosion of a detonator with or without added explosives when an electric firing circuit is completed by the rising water. In another modification, a switch comprising inter-geared toggle arms y, Fig. 8, carrying contacts v, is normally held closed by a spring restrained catch z the catch is released by a detonator u when it is electrically fired or by a float, and springs 3 then open the switch. In all arrangements, the fuses, carbon tubes or disconnecting switches are arranged in a bell to prevent the water short-circuiting the live ends of the compartment feeders after disconnexion has taken place. The auxiliary circuts may contain fuses which are blown after the detonator or other releasing means have been actuated so as to disconnect these circuits in the same way as the compartment feeders are disconnected.

Patent GB-638608-A (GB)
Title: Improvements relating to apparatus for collecting predetermined quantities of gas
IPC: G01N1/22
Filed: 1948-01-26
Abstract: A predetermined quantity of gas is collected from a gas source at constant rate by apparatus which comprises a movable gas holder bell 1 whose skirt is reciprocable axially in an annular space between the walls of a fixed internal dome 4 and a fixed housing 2 surrounding the bell and dome, a gas connection 6 between the interior of the bell and the exterior of the housing and an escape passage through the housing wall above the crown of the bell.  The escape passage is controlled by a three-way cock 9.  In operation, gas collection is started when the bell is at its lowest point and the space <PICT:0638608/III/1> above it is completely filled with water, as also are a dirt trap 10 and water flow tubes controlled by stop cock 8.  Cock 15 is opened and cock 14 adjusted to give a desired rate of flow from gas source through a blow-off 13, whilst cock 8 is shut, and cock 9 open to permit water to drip from capillary tube 11.  This latter, the water outlet, is adjustable in height relatively to the apparatus and is set before collection commences to give the desired rate of collection.  As water is lost through tube 11 the bell rises and gas is drawn into it whilst being confined therein by mercury which is in the annular space between housing 2 and dome 4.  On completion, cocks 9, 15 and 14 are closed.  To transfer the collected gas cock 8 is opened to admit water from a higher container which depresses the bell and forces gas out through tube 13 when cock 15 is opened.  Constancy of gas flow depends on maintaining a constant head of water on the water outlet 11.  Gas collection under reduced pressure is effected by closing cock 15 and connecting outlet 11 to the source from which the gas is derived or to a chamber at the same pressure.
