Title: Improvements in or relating to sluice gates
IPC: E02B7/20
Filed: 1921-09-29
Abstract: 189,287. Ransomes & Rapier, Ltd., and Stokes, Sir. F. W. S. Sept. 29, 1921. Disc.-A sluice gate is counterweighted so that it normally tends to open, and is provided with an automatic braking and releasing device normally preventing the gate from opening, but so controlled by a float or partially immersed weight that the gate will be free to open to a certain extent when the float or weight rises. The gate which is suspended from a cable A, Fig. 1, and counterweighted by a weight C is operated by a crab or other gear, one shaft F of which is screw threaded and carries the braking-device. The braking-device is mounted within a casing G, Figs. 1 and 3, having a projection G' engaging a fixed rod G<2> to prevent its rotation. Within the casing are two sets of friction discs, the set H, H<1>, H<2>, Fig. 3, engaging internal projections G<3> in the casing, while the set J, J<1> are mounted through a free. wheel drive on a sleeve J<2> having a projection J<3> running in a longitudinal slot in the shaft F. The disc H<1> is provided with an internally screwed boss H<3> engaging the screw thread on the shaft F, the disc H being provided with a similar boss but not screwed. A float or partially immersed weight L placed in a chamber communicating with the head water is supported on a chain L<2> running over a pulley M on the axle of which is a second pulley M<2> to which a rope N is attached which is connected at its other end to a lever 0. The lever O is fixed to a spindle carrying a second lever Q, the forked end of which engages a ring R carried in a recess in the boss H<4> of the disc H. The weight of the float normally forces the plate H inwards thus preventing the rotation of the shaft F. On the float L rising, pressure on the plate H is released and the plates H, H<1> come apart, this being assisted by a small weight P and also by springs placed between the plates, thus permitting the shaft F to rotate and the gate to rise under the action of the weight C. The braking device however is moved to the left by the screw until a position is reached, where the weight of the float L exerts sufficient pressure to lock the shaft. The rate at which the gate opens relatively to the rise of water may be varied by providing a series of holes N<2> for the attachment of the cord N. If it is desired that the amount shall not be proportional to the rise of water one of the pulleys preferably M<2> may be made cam shaped or eccentric.

A blank is worked by producing a bulge in it and moving the bulge along it, the blank suffering no reduction in area during the working. In one form, Fig. 4, a rod 2411 is rolled between rolls 20<SP>11</SP> and 22<SP>11</SP> an initial bulge in the rod being formed into a scroll by the grooves in the rolls. The rolls have staggered annular sections 40a to 40g which are individually driven at different speeds by gearing 42a to 42g in order to propel the scroll along the rod without altering the rod diameter. A tube supported by a mandrel may be similarly worked, or rolls formed with helical profiles may be used. The blank may be compressed axially during working. A plate 52, Fig. 5, may be rolled by a roll 58 which produces a bulge 62. The roll is lifted over the bulge at the end of a pass, before rolling the bulge back in the opposite direction. By releasing the rolling pressure, the bulge is rolled back into the plate surface. One face 60 of a ring 62, Fig. 6, may be similarly worked by rolls 68, a platen 66 constraining the ring during rolling. The inner surface of such a ring may also be worked while the ring is constrained by adjacent roll surfaces (Figs. 8 and 9, not shown).

Title: Improvements in the manufacture of carbon and of products derived therefrom
Inventor: DIJCK WILLEM JOHANNES DOMINICU
IPC: C01B31/00
Filed: 1947-09-29
Abstract: Petroleum coke suitable for use in connection with processes initiated as a result of atomic fissure of radio-active material, is obtained by subjecting non-residual petroleum hydrocarbons having a sulphur content of less than 2 per cent by weight to a thermal cracking and coking treatment under conditions which avoid or minimize contamination of the cracked products or finished coke by elements which effectively absorb neutrons and which yield not less than 15 per cent by weight of coke based on the feedstock. The cracking process may be effected in vessel made of calorized steel and the resulting coke must be treated with water which is substantially free from boron and lithium.  The feed petroleum hydrocarbons include petroleum gases from oil walls or refinery cracking operations, kerosene distillates, gas-oils, heavy distillates, heavy alkylates and Fischer-Tropsch distillates.  In a typical example (1), a Venezuelan gas oil cut of a boiling range of 220-380 DEG  C. and a sulphur content of 0.52 per cent was coked in a multicoil Dubbs coking unit using temperatures of 492 DEG  and 525 DEG  C. for the heavy and light oil cracking coils and temperatures of 494 DEG  and 535 DEG  C. for the coking and naphtha cracking coils with a pressure of 7.3 kgs/cms.  The coke was removed from the chambers with a river water having a content of boron of 0.08 parts per million.  The product comprised 15.64 per cent of coke, 55.98 per cent of motor spirit, and 4.42 per cent of gas oil.  Graphite may be produced by mixing this petroleum coke with an asphaltic binder, obtained by thermal cracking of non-residual petroleum hydrocarbons, and graphitizing the resulting mixture.

March 9, 1933, No. 26608. Divided on 399,791. Drawings to Specification. [Class 40 (iv).] In a system in which a plurality of selectors are associated with a common control circuit and in which the incoming test lead to each selector includes a resistance (of an associating relay or magnet) individual to the selector and a resistance in the control circuit, the test relay of the preceding selector has two differential windings connected in series between battery and earth, and the mid-point, which is thus normally at half-battery potential, is connected over a rectifier to the test wiper (or equivalent contact member). With this arrangement the test relay only responds to potentials greater than half-battery potential so that the reduced potential placed on all other selectors associated with the same control circuit when one selector is taken into use is equally effective in marking these selectors engaged as is the direct earth on a selector which is itself in use in a connection. The invention is described with reference to a group-selector switch identical with that shown in Fig. 14 of Specification 399,791.

Abstract: 849,608. Hydraulic apparatus. SHORT BROS. & HARLAND Ltd. June 25, 1959 [Aug. 19, 1958], No. 26643/58. Class 69 (2). An hydraulic jack comprises a piston 14, Fig. 1, reciprocatable in a main cylinder 10, an auxiliary cylinder 16 around and communicating with the main cylinder so that fluid comprised in the latter has access to the annular space 15 within the auxiliary cylinder, and a ring-piston 20 which is slidable in the auxiliary cylinder under a load and tends to reduce the volume of the annular space. The piston 14 is moved in one direction by fluid supplied through a connection 19 and in the other direction by fluid supplied through a connection 18, the annular space 15 and a duct 17. The ring piston is urged to a position reducing the volume of the annular space by a spring 22 engaging an abutment 23 on the main cylinder. During operation, excess pressure caused by shocks applied to the jack is accommodated by the fluid passing to the space 15 to move the ring piston against the spring. In a double-acting jack, an auxiliary cylinder and ring-piston are provided at each end of the main cylinder, the pistons being urged apart by a single spring or a pair of springs engaging an abutment on the main cylinder. In another embodiment, the ring-pistons 220, Fig. 3, are connected together by a sleeve 226 having an abutment 227 which is engaged by opposed springs 222 having their other ends engaging flanges on the auxiliary cylinders.
