Title: Improvements in or relating to isomerization of hydrocarbons
IPC: C07C5/27
Filed: 1966-09-13
Abstract: Alkyl aromatics are isomerized under isomerizing conditions in the presence of a noble metal/alumina/halogen catalyst and 20-200 p.p.m. by weight of water, said catalyst being periodically regenerated by isolating from the hydrocarbon, removing carbon deposits and contacting under oxidation conditions with an oxygen-containing gas having a water content of at least 3000 p.p.m. by volume of water. Hydrogen at the rate of 2000-10,000 SCF/Bbl may be added to the feed to suppress coke formation. Isomerization conditions specified are pressures of 100-1000 p.s.i.g. temperatures of 850-975 DEG  F. and a W.H.S.V. of 0.5-2. The catalyst may be a platinum/alumina/chlorine catalyst. C8 aromatic mixtures may be isomerized to yield o-, m- or p-xylene and/or ethyl benzene.

Title: Method of and apparatus for sealing pipe joints
IPC: F16L55/178
Filed: 1971-09-01
Abstract: 1417106 Injection moulding pipe joints WILLIAM PRESS & SON Ltd 14 Nov 1972 [1 Sept 1971] 40762/71 Heading B5A [Also in Division F2] A method of sealing a spigot and socket joint 4 between pipe sections 5, 6 comprises disposing mould halves 1, 2 to define a generally annular cavity around the joint, introducing a curable fluid sealing compound into the cavity via an inlet 8, exerting a pressure on the compound to force it into gaps in the joint and maintaining this pressure whilst the compound cures, and removing the mould halves to leave the compound around the joint in a hardened state. In the embodiment shown the pressure on the compound is produced by a cylinder (10) and ram (11) carried by mould half 2 (Fig. 5, not shown). The mould may be of a flexible PVC.

Abstract: 1,194,983. Hydraulic actuators. P.S. DOISTUA and C.A. GOIRI. Aug.27, 1968 [Nov. 23, 1967], No.40850/68. Heading F1P. [Also in Division B3] A rotary machine tool head 1, 2 having a fluid operated actuator piston 16 for operating a chuck, is provided with a rotary part 3 which includes a valve assembly, Fig. 4, supplied with oil under pressure when the actuator is to be operated and arranged to trap oil in the actuator when the oil supply is cut-off. The actuator piston 16 slides in a cylinder defined by the rotary parts 1, 2, 3 and divides the cylinder into chambers 15, 23. The oil is trapped in these chambers when the oil supply is cut-off and hence the actuator is locked in its adjusted position. To operate the actuator oil is supplied to the valve assembly through one or other of ducts 11, 21 by selective pressurization of annular grooves 9, 19 in a stationary block 4. Assuming the duct 11 is pressurized, then the right hand non-return valve 37 opens to allow oil to flow through ducts 12, 13, 14 into the actuator chamber 15. The increase in the oil pressure in the duct 11 causes leftwards displacement of a piston 27 and consequential opening of the left hand non-return valve 37 so that oil in the opposite chamber 23 exhausts through ducts 22, 21. If the duct 21 is pressurized, oil flows to chamber 23 for operation of the actuator in the reverse direction.

[Also in Division E1] A mobile loader having an endless conveyer and a gathering head, including a ramp and gathering arms has, in place of the conventional nose-piece a dinting implement comprising a pluraliy of chisels 11 which are reciprocated fore and aft of the loader. The implement includes a motor, e.g. an hydraulic motor, driving a shaft 9, carrying cams 15. The latter operate spring-loaded hammers 14 so that when the cams clear walls 16A of the hammers their spring-loading urges them to strike the chisels 11. The chisels are slidable relative to stop-pins 13 and are spring-loaded to their forward positions in which they remain clear of the hammer heads 14A, so that the hammers only strike the chisels when these are pressed against a surface. The chisels are operated in pairs in staggered relationship. The implement is detachable and replaceable by the conventional nose-piece.

[Also in Division B8] Lateral flanges (14) (Fig. 1, not shown) on wall sections of one of a pair of crossed blanks of material with thermoplastic properties are turned inwardly to overlie wall sections (10) of the other blank by the flared mouth 34, Fig. 4, of a reciprocating female die 32 co - operating with a stationary male die 20 to set up the wall sections, and the flanges (14) and sections (10) are bonded together by heating means incorporated in holes (35) (Fig. 6, not shown) in the walls of the female die. The blanks, which are fed to the dies either singly, or in pairs each assembled in a conveyer pocket wherein they may be subject to radiant pre-heating, are initially clamped on the male die by a platen head 29, Fig. 4, also containing heating elements 30, and the wall sections 10 are turned inwardly before the wall sections 12 by an inwardly projecting pair of spring prongs (36) (Fig. 6). The female die 32 makes a short dwell at the bottom of its cycle to ensure complete bondage of the seams and the carton (see Division B8) is finally ejected by upward movement of a stripper plate 22 mounted on a hollow shaft 23 through which a blast of air is blown to complete the ejection. The male die 20 may be cooled by circulation of a coolant through a chamber 26. For heavy duty cartons the seams are reinforced by additional pressure at the carton edges due to engagement of longitudinal splines (39) (Fig. 11, not shown) in the female die within corresponding grooves (40) in the male die, causing the thermoplastic coatings of the blanks to bond round the edges of the wall sections 10. The carton material may be paperboard treated with thermoplastic material or fibrous sheet material faced with polyethylene or polypropylene film.

Abstract: 1425456 Switching circuits with hysteresis CLARKE CHAPMAN Ltd 13 Sept 1973 [23 Sept 1972] 44101/72 Heading H3T [Also in Division G1] The intensity of radiation, e.g. from a flame is monitored by a semi-conductor detector whose circuit includes a trigger circuit having an adjustable hysteresis feedback loop. As shown, a phototransistor Tr1 feeds amplifier A1 and trigger circuit formed of transistors Tr2, Tr3. An increase in detected radiation causes the current via R6 to make point B positive and switch on Tr2. This causes Tr3 to switch off, resulting in energization of the relay RL1 and a feedback voltage to be applied via set hysteresis potentiometer VR3, such that for switch off of the relay, the amplifier A1 output must fall somewhat below the switch on level for the trigger. R7 provides fixed hysteresis, VR2 sets the switch on lead, VR1 sets the gain for amplifier A1. Amplifier feedback circuit may be modified Fig. 2 (not shown) to provide a variable time delay, so that the relay is held energized in the presence of flame flicker. The effects of longer term (25-30 seconds) fluctuations of intensity may be obviated by providing a variable delay in the relay circuit, Fig. 3 (not shown). The operation of the relay may control fuel valve closure or an alarm. The relay may be substituted by thyristors.
