Title: Vaporizing heavy hydrocarbon feedstocks without coking
Inventor: PARKHURST HUGH J
IPC: C10G45/58
Filed: 1984-08-20
Abstract: A method for a vaporizing heavy hydrocarbon which avoids the formation of coke in the feed heaters and is useful in a process for upgrading and/or converting the heavy hydrocarbon to lighter products. Heavy hydrocarbon feedstock (10) is heated (12) to a temperature below its coking point, then mixed (at 20) with hydrogen (16) heated (at 18) to a temperature sufficient so that the hydrocarbon feedstock is vaporized without forming coke. Alternatively, the heavy hydrocarbon feedstock can be fractionated to provide a light IBP-550 DEG F (288 DEG C) liquid fraction, and a heavy 550-850 DEG F (288-454 DEG C) liquid fraction. The light fraction is mixed with hydrogen and heated to a temperature sufficiently high, so that upon being mixed with the heavy liquid fraction the latter is heated through its dry point and vaporized without coking. The resulting vaporized hydrocarbon is usually further heated before being fed to a reaction step, such as hydrodealkylation.
Patent GB-2164884-A (GB)
Title: An adjustable spanner
Inventor: MCDOUGALL GREGORY JOHN
IPC: B25B13/14
Filed: 1984-09-07
Abstract: A holder (10 to 12) is formed with an elongate aperture for receiving first and second members (1 and 2) formed respectively with first and second gripping surfaces (3 and 4). The first member (1) is formed with first and second parallel edges (14) and an elongate portion (15) of the second member (2) is axially movable within the elongate slot (16) defined by the first and second parallel edges (14). A series of regularly spaced projections (8) formed on the first and second parallel edges (14) and a series of regularly spaced projections (9) on opposite edges of the elongate portion (15) respectively engage opposite-handed external and internal screw threads (6 and 7) (Fig. 3) on a sleeve (5) mounted in an aperture (18) intersecting the elongate aperture so that the sleeve (5) is incapable of movement relative to the holder (10 to 12) along the axis of the sleeve (5). Rotation of the sleeve (5) therefore causes the first and second members (1 and 2) to move in opposite directions, thus causing the first and second gripping surfaces (3 and 4) to move towards and away from each other. To prevent lateral movement of the sleeve (5) transverse to the longitudinal axis of the sleeve (5), and thereby ensure free rotation of the sleeve (5), the aperture (18) for the sleeve (5) is formed with bevelled edges (19) (Fig. 6) which extend tangentially to the external screw thread (16) formed on the sleeve (5). <IMAGE>

Title: Runway beam system for trolleys
Inventor: ECCLESTON BARRY CRAIG
IPC: E01B25/24
Filed: 1984-11-08
Abstract: The system includes two relatively movable runway beams (14A, 15), each having an end-stop member (30A or 30B) for preventing a trolley over-riding the end of the beam except when the other beam is in end-to-end alignment therewith. The end-stop members are movable between first positions (shown) in which they block trolley movement beyond the beam ends and second positions (see dashed for 30B) in which they do not block the said trolley movement. The end-stop member (30A) of one said runway beam (14A) has a part (36) that, during movement from the first to the second position, engages a part (32B) of the end-stop member (30B) of the other runway beam (15) to move that member also from the first to the second position. A latch part (40) moves (when the said members reach their second positions) into a latching relationship. <IMAGE>

Title: Improvements in or relating to meters
Inventor: MORGAN ANTHONY
IPC: G06M1/10
Filed: 1985-02-08
Abstract: An inductive electricity meter or reversible fluid flow meter has a disc 1 whose rotation occasions photocells 2, 3 to produce output signals from which a control unit 5 generates pulses each corresponding to a revolution of disc 1. The control unit 5 also divides up the pulses according to the direction of rotation and directs them towards either forward counter 6 which records consumption of electricity or reverse counter 15 which records fraudulent reversal of disc 1. The meter has two single-pulse stores 14 and 20 to ensure that the amounts registered by counters 6 and 15 are maintained correct even when spurious single-reverse pulses occur, caused by inherent design characteristics of the meter. <IMAGE>
Patent GB-2174349-A (GB)
Title: Carriers for use in conveyors
Inventor: BALL KENNETH MICHAEL JOHN
IPC: B65G17/08
Filed: 1985-05-03
Abstract: A conveyor surface is formed by a plurality of grid carriers 10. The conveyor includes a straight section 12 and a curved or spiral section 14 (only part of which is shown). The conveyor is used to transport loaves whilst they are cooling, and it is important that the distance between adjacent carriers does not exceed a predetermined amount during the straight or curved path. Accordingly each grid carrier is tapered from a central region towards a tip 20 at a common side of the conveyor. Thus the space 18 between the tips 20 decreases as the conveyor travels around the curved path 14, and the gap 22 between the opposite sides of the carriers 10 increases as the conveyor goes around that curved path, but, whilst the conveyor provides a supporting surface, the spaces 18 or gaps 22 do not exceed a predetermined amount either on the straight or curved section. The carriers may be snap-fitted onto projections on the drive chain. <IMAGE>
