Title: Improved means associated with cranes for the operation of tip buckets
IPC: B66C1/66
Filed: 1921-04-14
Abstract: 185,785. Reid, W., and Macnamara, C. M. April 14, 1921. Addition fo 159,811. Tip-buckets. - The invention described in the parent Specification comprises a cylinder B suspended from the jib of a crane and co-operating with members on the bucket so as to bring the tipping-axis of the bucket into a predetermined plane and then to disengage a locking-device to permit the bucket to tip by gravity. According to the present invention the construction is modified so that the bucket can be raised to any height without tipping, and discharged when subsequently lowered relatively to the cylinder B, and improved means are provided for bringing the tipping-axis of the bucket into the desired plane. The bucket is normally locked in the bail D by arms b on the latter which drop between lugs a on the bucket and can be raised for disengaging the bucket by raising a T- headed member g<1>. When the full bucket is raised, the guidecylinder q above the crane-hook enters the suspended cylinder B, and co-operates with guides therein to bring the tipping axis of the bucket into a predetermined plane, but the bucket is not released, the T- head g<1> merely passing between a pair of spring-closed pivoted hooks i. The bucket can now be raised to any desired height, lifting the cylinder B which is connected with a slider l running in guides on the jib. On lowering the bucket, the cylinder B is brought to rest when the slider l reaches an adjustable stop m<2> in the guides and the hooks i detain the T- head g<1> so that the bucket is released, The T- head subsequently opens the hooks i against the pressure of their springs and the arms b drop into position to lock the bucket which is selfrigbting when empty. In order to provide time for the tipping of the bucket before the arms b drop, the hooks i may be pivoted on cross-heads wbich slide in guides on the cylinder B and are supported on springs; the T-head g<1> does not escape from the hooks until the cross-heads have reached the limit of their downward movement on the cylinder. Fig. 7 is a section of the suspended cylinder B. When the bucket is raised, projections q<1> on the cylinder q, Fig. 4, on the crane chain engage with inverted V-slots o<1> in an inner cylinder o which can slide and turn in the suspended cylinder B, and projections o<2> on the cylinder o engage with inclined V-slots n<1> in a fixed inner cylinder n which determines the plane of the tipping-axis of the bucket

IPC: H02K19/10
Filed: 1954-04-14
Abstract: 760,269. Electric motors. SHORT BROS. & HARLAND, Ltd. April 13, 1955 [April 14, 1954], No. 11008/54. Drawings to Specification. Class 35. In an inductor motor for high-frequency polyphase current, the number of teeth on the stator and rotor differ by the pole number of the stator winding, so that the speed of the motor is inversely proportional to the number of stator poles and rotor teeth, the stator and rotor being of moulded ferrite. As described, the stator, which is wound for a two-pole fundamental flux distribution has sixteen teeth while the rotor, which may be wound, has eighteen teeth producing a rotational speed of one-ninth of the supply frequency. The motor is rendered selfstarting by winding the stator to produce a harmonic flux distribution providing a higher pole-number and using the induction motor effect to provide a run-up speed which may be sufficiently close to the synchronous speed to enable it to synchronize.

Abstract: 829,661. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. April 9, 1957 [Nov. 30, 1956], No. 11502/57. Drawings to Specification. Class 39(4). In a heterogeneous reactor, a continuous stream of pellets of natural uranium are introduced at the top of a tank filled with acidified heavy water which acts as both coolant and moderator and fall freely to the bottom. The pellets are partly dissolved and the plutonium and fission products produced therein are removed in a uranium recovery plant. Undissolved pellets are removed from the base of the tank for reprocessing. Disassociated deuterium and oxygen are recombined. Vertically adjustable control rods of hafnium and zirconium are positioned in the tank. The heavy water contains a small quantity of uranium and is acidified with deuterium sulphate to prevent the precipitation of uranium dioxide. Losses due to fissioning of the plutonium formed in the outer layers of the fuel pellets are reduced as the surfaces of the pellets are removed first by the dissolving action. The corrosive action of the solution on the tank is less than that in a homogeneous reactor as the concentration of the uranium in the solution is low. Specification 817,751 is referred to.
