Filed: 1928-02-20
Abstract: 288,566. Koppers Co., (Assignees of Lovett, J. A. B.). April 12, 1927, [Convention date]. Discharging.-The head of a pusher ram for discharging horizontal coke ovens is constructed with a projection which engages that portion of the charge offering the greatest resistance, i.e. the lower part, before the remainder of the head contacts with the coke. As shown, the ram head 20 is carried by a motor-operated bar 15 mounted on a wheeled carriage 12 and is formed, at its lower part, with a projecting portion 23 having a vertical face 24 which, at the commencement of the discharging operation exerts pressure on the bottom layer of coke in the oven 10 before the main surface 25 of the head 20 engages the upper parts of the charge. Fig. 3 shows a modification in which the head 20 is formed, in addition to the projection 23, with further projections 31, 32, 33 arranged in steps. In each case, there is pivoted to the lower part of the projection 23 a counter weighted plate 26 which is so arranged that it can pivot forwardly only and so ride over any loose coke during withdrawal of the pusher.

Title: Nuclear reactor
IPC: G21C1/12
Filed: 1946-02-21
Abstract: 817,754. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 21, 1946 [Feb. 16, 1945], No. 5513/46. Class 39(4). A nuclear reactor comprises bodies of fissile material geometrically arranged in a low neutron absorbing moderator material, means for passing a fluid in heat exchange relationship with the fissile material, and means for extracting heat from the fluid. Fig 2 shows a cross-section of a graphite moderated helium cooled reactor. The lower chamber 35 serves as a gas inlet and fuel element discharge chamber ; above this in the chamber 37 is the reactor core (not shown) comprising graphite bricks secured together by dowel pins and provided with vertical fuel channels, the lattice being surrounded on all sides and at the top and bottom by less pure graphite which acts as a reflector. Guide tubes 58 fit into the tops of the fuel channels and are provided with slots to allow the coolant gas to pass to the discharge nozzles 57. Above the outlet gas chamber is a neutron and gamma ray shield comprising a layer of steel plates 64 and a layer of graphite 62 supported on a steel floor 60 ; the guide tubes extend through the shield and are normally closed by removable shield plugs of steel and graphite, similar to the neutron and gamma ray shield. The dome 39 is provided with a manhole 73 to allow access for loading fuel elements into the reactor. Each row of fuel element columns is supported on two cans 59 provided with small apertures through which the helium coolant can pass and with large apertures through which the fuel elements can pass ; thus if the cans are moved to place their large apertures underneath the fuel channels, the row of fuel elements is discharged into the chamber 35 from which the fuel elements may be removed through a gate valve 89. The reactor is surrounded by a concrete shield 96, and the space between the reactor and the shield is filled with water. Figs. 10 and 11 show a cross-section and plan of fuel elements in a fuel channel in the moderator bricks 41. The uranium plates 49 are spaced apart by lugs 50 and rest on a ledge 48 in a cylindrical graphite cartridge 40. The cartridge is provided with a throat 46 to restrict the flow of coolant gas, and the areas of these constrictions are varied at different parts of the lattice to secure the most efficient heat removal from the system. The thickness of the uranium plates 49 is also varied; those which are used in the centre of the lattice are thinner, to provide a greater cooling surface, than those near the outside. The reactor includes five safety rods and four control rods, of which one is shown in Fig. 23 ; this comprises two concentric tubes arranged so that cooling water can circulate through them. The positions of the control rods may be controlled automatically to maintain a constant neutron flux. The helium leaving the reactor may pass through a heat exchanger to a filter which removes any solid fission products entrained by the helium, and thence through a compressor back to the reactor. Specifications 817,751 and 817,752 are referred to.

The belt 9 has transverse ribs 11, Fig. 1, a pair of aligned perforations 13 (not shown), 14, Fig. 2, between each pair of ribs, and a narrower "valve" portion 16 having filtrate-collecting chambers 17 (each receiving from a number of perforations 14) and holes 18 each communicating with one of the chambers 17. Slurry is supplied at 7 to a slurry-retaining device 7a (see below) and its distributionover themedium is assisted by compressed air supplied to an opening 34 in an extension plate 36 of a suction box 22, Fig. 1. The suction box comprises two compartments 23, Fig. 1, each having a longitudinal slot 24. The cake is loosened by compressed air supplied to an opening 37 in an extension plate 39. Washing sprays 32 are provided. The slurryretaining device 7a, Fig. 7, has a one-piece flexible strip 43 depending from three sides of a frame 42 and a further transverse flexible strip 46.

Title: Method of and apparatus for the production of motive force
IPC: F03B17/02
Filed: 1920-02-24
Abstract: 163,791. Merz, F. Feb. 24, 1920. Buoyancy motors.-A buoyancy motor comprises a series of floats attached to an endless chain and immersed in a liquid, which are successively rendered buoyant by the introduction of a liquid which vaporizes at the temperature of the surrounding liquid. The casing consists of a U-shaped chamber 1, two pipes 3, 3<1>. and an upper chamber 5, and is partly surrounded by a jacket 14 in which warm gases may circulate. The working liquid is forced into the openbottomed floats 25 through an inlet box 13 with an automatic spring-controlled valve by means of the pump 12 which is operated by a cam gear from the driving shaft 16 so as to make one stroke as each float passes over the inlet box. The working liquid evaporates and expels the surrounding liquid rendering the vessels buoyant. The valves 27, the heads of which are made hollow, close under the pressure of the vapour, but open when the floats reach the surface of the liquid. On the descent, the valves remain open and the liquid rises in the floats until it reaches the valve which tends to float and thus closes. The vapour which escapes from the floats at the top of the apparatus is led to a condenser 8, whence it is drawn by the pump 12 to be used again. The motor may be worked by heating the liquid in the casing, or by cooling the condenser, or by both methods, according to the nature of the working liquid.

Abstract: 720,761. Magnetic amplifiers. GENERAL ELECTRIC CO. Feb. 27, 1953 [Feb. 29, 1952], No. 5545/53. Class 40 (4). In a magnetic amplifier system comprising a balanced pair of magnetic amplifiers 11, 12, in which the control windings 17, 18 are serially connected and shunted by a pair of identical impedances 32, 33, current to provide bias is applied over the centre taps of the impedances and control windings respectively. A potentiometer 34 provides a means of equalizing the bias and a resistor 51 provides adjustment of the operating point. The amplifiers are connected differentially and feed a load 37 through load resistors 38, 39. The impedances 32, 33 have time constants considerably larger than those of the control windings to improve the response of the amplifier. A modification including a rectifier bridge in the bias input circuit to cater for an alternating bias current is described with reference to Fig. 2 (not shown). The amplifier is shown feeding the excitation windings of a generator.
