Title: Apparatus for the extraction of hydrogen from gas mixtures
IPC: C01B3/50
Filed: 1967-03-03
Abstract: Hydrogen is separated from a gaseous mixture by contacting the latter with palladium powder or sponge in an absorption zone, the palladium being cyclically moved into a desorption zone having a higher temperature than the absorption zone, and then back into the absorption zone, hydrogen desorbed in the desorption zone being led to a receiver. In the apparatus of Fig. 1, the gaseous mixture from a reservoir 8 is caused to fluidise palladium powder in a fluidiser 1. An overflow pipe 5 allows palladium powder to flow by gravity through a seal 6 to a second fluidiser 2, where it is fluidised by hydrogen circulated therethrough and through the pipe 21 by a compressor 20, and an overflow pipe 7 and ejector 34 remove it from the fluidiser 2 via pipe 36 to a cyclone 37, where the palladium powder is separated from the hydrogen and returned to the fluidiser 1. The bed in the fluidiser 1 is maintained at, e.g. 100 C, by a water jacket 41, to allow hydrogen to be absorbed by the palladium, while it is desorbed by maintaining a temperature of e.g. 200 C in the fluidiser 2 by heaters 43. Hydrogen is bled from the pipe 21 to a receiver 32. In the apparatus of Fig. 2 palladium powder is packed in a fine honeycomb of stainless steel in a rotary disc 50, and the gas from which hydrogen is to be absorbed is passed through part of the disc by conduits 59 and 60, while heated pure hydrogen is circulated through the remainder via conduits 61, 62, and bled off from this circuit to a receiver 68.

Title: Display device with video signals interleaved in segments of a cyclical storage
IPC: G09G5/39
Filed: 1967-03-21
Abstract: and G4H. A cyclic trace display device e.g. a television display 33 (Fig. 1) is selectively fed with data from a cyclic buffer store 21, control means supplying data from every nth (e.g. 2nd) block location to the display, the blocks being displayed on successive lines. In the embodiment described data from a keyboard 10 is converted to video and binary coded decimal form in a composer 12 and parallel to serial converter 13 respectively and read in, on leads 20, 22 (Fig. 9), when a write pulse enables AND gates 116, 117, via OR gate 120 and sequentially enabled AND gates 121- 124, to one of four parallely connected delay lines 110-114. Output signals via AND gates 127-130 and OR gate 138 are supplied (1) to the T.V. display via an AND gate enabled except during vertical re-trace, (2) to marker bit control 55 and (3) to AND gate 119 for re-entry into the store. During the first cycle of the delay line blocks of data, 1, 2, ... 78 (Fig. 2) are displayed, blocks 79 to 143 being fed from the delay line during horizontal retrace. During the second cycle blocks 79 ... 143 are displayed and during vertical re-trace binary coded data in blocks KB1 ... KB12 is read out. During a write in operation marker bits are inserted-in the last bit of the last byte of data-the marker bit control 55 prior to a writing operation destroying old marker bits. When the marker bit control locates a binary coded decimal marker bit during vertical retrace the output of OR gate 134 becomes positive and a bit counter is then enabled to start read in of data, the AND gate 119 being closed to prevent re-entry of the marker bit. The delay lines may be cleared by depressing switch 140 and before new data is read in one initial marker bit is inserted in each block in the last bit position by depressing switch 144 which allows properly timed pulses on line 145 to be stored. When data is written in the initial marker bit is destroyed.

Title: Rolling element bearings
IPC: F16C33/78
Filed: 1972-11-10
Abstract: A rolling element bearing of the type comprising two annular bearing elements between which run a plurality of rolling elements, in which the interior of the bearing is sealed by an annular seal between the two annular bearing elements.

Title: Motion compensated crown block system
IPC: C09D127/06
Filed: 1973-07-24
Abstract: A motion compensated crown block system in which a crown block sheave means is movable along a vertical path defined by a framework usually forming part of a drilling rig which is supported on a vessel. The crown block sheave assembly, which carries the hook load, is principally supported by inclined fluid pressure cylinder and piston means having one of their ends pivotally connected to the sheave means and their other ends pivotally connected to the framework in lateral spaced relation to the generally vertical pathway of the sheave means. Changing inclination of the cylinder and piston means during relative movement of the crown block sheave assembly and vessel provides variation in the piston reaction vertical force component which is caused to be nearly proportional to the change in fluid pressure in the cylinder and piston means. Load variation of less than 5 percent of the hook load is achievable over the full path of travel of the sheave means and is in the order of 2 percent over a major portion of said path in which the crown block sheave assembly travels. Means for sensing motion of the crown block sheave means relative to the sea bed are also provided so that the crown block sheave means will be virtually stabilized to maintain unchanged relation with respect to the sea bed during heaving of the vessel as caused by wind and wave action. Means are also provided for reducing to a minimum travel of the sheave cables over idle sheaves during travel of the crown block sheave means in its vertical path.

Title: Crimping tool
IPC: H01R43/042
Filed: 1974-07-11
Abstract: A tool, especially for use in the splicing of telephone wires, comprises a conveyor wheel which is rotatable to convey the leading terminal of a side-by-side strip of channel-shaped electrical terminals, connected together by carrier strips of plastics material, onto a crimping anvil. A terminal strip guide block, which is exchangeable, partially surrounds the conveyor wheel and bears cutting blades, which by reason of the movement of the strip of terminals with respect to the guide block, sever the leading terminal from the strip prior to its being positioned on the anvil. A movable crimping die, which is also exchangeable, is provided which cooperates with the anvil for crimping the leading terminal to wires which have been previously inserted into the terminal. The guide block carries a blade which enters a slot in the movable die to trim the wires prior to the crimping operation taking place. Since the strip cutting and wire cutting blades are disposed on the guide block, the tool can be changed over for use with terminals of different length simply by exchanging the guide block and the crimping die.

Title: Intake and exhaust manifold system for internal combustion engine
IPC: F02M31/08
Filed: 1975-07-17
Abstract: A multi-cylinder internal combustion engine of the type having an auxiliary combustion chamber associated with each main combustion chamber, and connected thereto by a torch opening, is provided with a manifold system in which the exhaust gases are used to heat a rich air-fuel mixture supplied to the auxiliary combustion chambers and is also used to heat the lean air-fuel mixture supplied by the primary carburetor barrel to the main combustion chambers, but the lean air-fuel mixture supplied by the secondary carburetor barrel is not heated. The secondary carburetor barrel comes into action only when the engine is operating under heavy load, so that the unheated additional lean mixture improves the volumetric efficiency and thereby improves the power output of the engine. Thin wall liners and heat transfer plates having low thermal capacity are provided for the exhaust passages in the engine, the interior of the exhaust manifold, and the heat exchange surfaces for heating the rich mixture and that portion of the lean mixture provided by the primary carburetor barrel.
