Title: Two-stage hydroprocessing of heavy oils
Inventor: SHINN JOHN H
IPC: C10G65/02
Filed: 1983-06-16
Abstract: The hydroprocessing of heavy hydrocarbonaceous oils containing liquid components boiling above 500 DEG C is effected by a process which comprises:   (a) contacting in a first reaction zone 20 said oil feed 5 with hydrogen 15 & 50 under hydrogenation conditions including a hydrogen partial pressure above 35 atmospheres to produce a first liquid effluent 25 comprising liquid components boiling above 500 DEG C; (b) contacting in a second reaction zone 30 at least a portion of said first effluent 25, said first effluent portion containing liquid components boiling above 500 DEG C, with hydrogen under hydroprocessing conditions in the presence of a hydrogenation catalyst to produce a second effluent 35 comprising liquid components boiling above 500 DEG C; and (c) recycling at least a portion 90 of said second effluent to said first reaction zone, said recycled portion containing a substantial quantity of liquid components boiling above 500 DEG C.   The heavy oil can contain added solids such as porous metal getter particles, dispersed hydrogenation catalysts, and/ or coal or coal-containing particles. <IMAGE>
Patent GB-2143252-A (GB)
Title: Desulphurizing coke
Inventor: KAPNER ROBERT S
IPC: C10L9/02
Filed: 1983-07-13
Abstract: Delayed coke is desulfurized by first contacting the coke with an active sulfur-bearing gas at 1400 to 1600 DEG C for 5 to 30 minutes, purging the gas, and then holding the coke in contact with the gas at said high temperature for approximately one hour. An alternative process provides for desulfurization of delayed coke by modifying the second step of the prior process to dilute or replace the sulfur-bearing gas with an inert gas. In a third alternative, the foregoing process is further modified by lowering the temperature during the second or holding step to maintain the reaction between the sulfur-bearing gas and the coke.
Patent GB-2149646-A (GB)
Title: Earring fastening
Inventor: KNOWLES ALBERT HENRY
IPC: A44C7/00
Filed: 1983-11-14
Abstract: An earring fastening is in the form of a disc made of an entirely flexible material with a single hole punched through the centre and pushed onto the shank of an earring after it has been passed through the lobe of an ear, gripping the shank in the position of maximum comfort to the wearer, any where along its length. Because of there are no rigid elastic properties, the disc will fit onto any thickness of shank, returning after use to original tightness and cannot be bent or crushed in a manner which would render it unserviceable. <IMAGE>

Title: Filter cloth construction for a filter press
Inventor: THORN JOHN
IPC: B01D25/176
Filed: 1984-02-23
Abstract: A filter press plate 11 carries filter cloths 12, 13 on opposite sides, and the cloths are joined together, through a slurry feed hole 15 in the plate, by an impervious tube 14. The tube 14 is of double layer impervious rubber, plastic or coated fabric, and its ends are bonded or vulcanised to respective cloths 12, 13. There is no tendency for filter cake to stick to the impervious tube 14 and no build up of filter sludge at the join of the tube 14 to the cloths 12, 13, because the join is by bonding or vulcanising and not stitching. <IMAGE>

Patent GB-2149271-A (GB)
Title: Television display system with reduced line-scan artifacts
Inventor: POWERS KERNS HARRINGTON
IPC: H04N5/44
Filed: 1984-11-05
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.

Title: Welding torch cleaner for robotic welding
Inventor: WINTERFORD CHARLES RAYMOND
IPC: B23K9/32
Filed: 1985-01-12
Abstract: A baseplate 20 carries an axially-advanceable rotating cutter 26. A V-block and clamp head 23, 24 are aligned on the plate to locate and secure a robot-positioned welding torch nozzle 17 in a vertical attitude. After clamping the nozzle in position, the rotating cutter is advanced into the nozzle bore to remove accumulated internal weld spatter. The machined-away weld spatter can therefore be discharged under the influence of gravity or by a blast of purging air applied to the torch nozzle. <IMAGE>

Title: Calipers
Inventor: FARROW JOHN REGINALD
IPC: G01B3/16
Filed: 1987-08-27
Abstract: Calipers have mutually pivoted legs (1,2) biased apart by a spring (3) and with a tip spacing adjustable by a nut assembly (6,9) on a screw- threaded shaft (4). This shaft may be pivoted on one leg (1) and be engageable in a detent in an abutment (7) on the other leg (2) with which the nut assembly (6,9) co-operates to set the calipers in the gauging position. The shaft (4) may then be pivoted clear to release the legs, without disturbing the nut assembly, and subsequently restored to the exact gauging position. Alternatively the shaft (4) passes through the abutment and the gauging position is set by a quick- release nut assembly acting against one side of that abutment and a setting nut on the other side, which latter is used to restore the legs to the exact gauging position. These principles are applicable to inside as well as outside calipers. <IMAGE>

Title: Maintaining cache consistency
Inventor: RUBINSTEIN JON
IPC: G06F12/08
Filed: 1989-02-22
Abstract: A respective bus watcher is coupled with each cache memory in a multiprocessor computer system. Such a system may comprise multiple memory mutators capable of updating the contents of main memory. Each bus watcher ensures that any writes to memory by other memory mutators results in invalidating a corresponding entry in its processor's cache memory. It does this by monitoring, 60, writes to, main memory by other memory mutators and by monitoring I/O activity by its processor. The bus watcher maintains, 64, an array of addresses of data in its data cache memory. The method is capable of working with a processor unit which does not provide information, when doing memory read, which tells whether the read will result in updating of cache memory. <IMAGE>
