Title: Process for the arylation of aromatic compounds
Inventor: MCCALL ERNEST BRYSON
IPC: C07D333/76
Filed: 1960-11-09
Abstract: An aryl (carbocyclic or heterocyclic) group is introduced into an aromatic (carbocyclic or heterocyclic) compound by heating the latter with an aromatic compound containing a nuclear-bound sulphonyl halide or sulphonic acid group or a salt of the latter which decomposes under reaction conditions; either reactant may contain an alkyl, aryl, halogen, carboxylic ester, alkoxy, aryloxy or nitro substituent.  Where either compound is heterocyclic this may be of the furan, thiophene or pyridine type and may contain one or more condensed benzene rings.  The reactants are heated at 125-300 DEG C. for 2-30 hours with a mol ratio of aromatic compound to arylating agent of 1-25 : 1.  The examples describe the preparations of (1) terphenyls from diphenyl and benzene sulphonyl chloride; (2) phenyldibenzothiophenes from dibenzothiophene and benzene sulphonyl chloride; (3) terphenyls from diphenyl and benzene sulphonic acid; (4) diphenyl from benzene and benzene sulphonyl chloride; (5) phenylnaphthalenes from naphthalene and benzene sulphonyl chloride; (6) methyl-p-diphenyloctanes from 2-methyl-2-phenyloctane and benzene sulphonyl chloride; (7) diphenyl phenyl ethers from diphenyl ether and benzene sulphonyl chloride; (8) terphenyls from diphenyl and benzene sulphonyl bromide; (9) m-1,3-bis-(diphenylyl)benzenes from diphenyl and benzene-m-disulphonyl chloride; (10) p-tolyldiphenyls from diphenyl and p-toluene sulphonyl chloride; (11) tolyl naphthalene from p-toluene sulphonyl chloride and naphthalene; (12) p-isopropylphenyl-naphthalenes from naphthalene and p-isopropylbenzene sulphonyl chloride; (13) t-butylterphenyls and di-t-butylquaterphenyls from diphenyl and p-t-butylbenzene sulphonyl chloride; (14) p-t-butylphenylnaphthalenes from naphthalene and p-t-butylbenzene sulphonyl chloride; (15) nitroterphenyls from diphenyl and p-nitrobenzenesulphonyl chloride; (16) sexiphenyls from diphenyl and 4,41-diphenyldisulphonyl chloride; (17) pyridyldiphenyls from diphenyl and pyridine-3-sulphonyl chloride.  The Provisional Specification also refers to the use of esters of sulphonic acids, particularly aryl esters, and alkali or alkaline earth metal salts of sulphonic acids as arylating agent and to alkylating processes employing an alkyl sulphonic acid or halide, ester or salt thereof.
Patent GB-1298894-A (GB)
Title: A pendulum control device, in particular for hydraulic pit prop units
IPC: E21D15/58
Filed: 1970-08-10
Abstract: 1298894 Valves KLOCKNER-WERKE AG 10 Aug 1970 [2 Sept 1969] 38457/70 Heading F2V [Also in Division G3] A pendulum 3, Figs. 1 and 2, operates a pair of valves 9, 10 when deflected, the valve 9 controlling a servomotor 52, Fig. 3, which may be used to adjust the inclination of a pit prop while the valve 10 has its ports interconnected with the valve 9 and compensates for the effect of the fluid-pressure forces in the valve 10 on the pendulum. Movement of the pendulum about its pivot 2 displaces a beam 6 connected by yokes to the closure members of the valves. Each closure member 16 pivots about a spring- loaded spherical bearing 28 to co-operate with a pair of seats 17 to which fluid may flow from a constant pressure supply 25 in the valve 9 and which receive fluid through the pipes 79 and 80 in the valve 10. The position of the closure member in the valve 9 determines the volume of flow in the pipes 79 and 80 through pressure actuated valves 81, 82 and through similar valves 66, 67 determines the fluid-pressure signal to be applied through pipes 63, 90 and 64, 91 to spring-loaded relay valves 94, 95 controlling the servomotor 52. The valves 66, 67 and 81, 82 may be of the kind having an elastic conduit arranged to be constricted by external fluid-pressure and the valve and servomotor sections 55 and 51 of the system are coupled together by plug-in connectors 49, 50 having ports to permit rotation through 180 degrees. A line 70 which supplies the port 25 through a filter 105 also supplies the relay valves 93, 94. In a modification, two servomotors at 90 degrees to each other are controlled by a universally mounted pendulum.

Title: Means for raising and lowering vehicle frames
IPC: B60P1/64
Filed: 1969-08-01
Abstract: 1,220,779. Container traffic. DAIMLER-BENZ A.G. 1 Aug., 1969 [3 Aug., 1968], No. 38740/69. Headings B8E and B8Q. In a vehicle which has bellows pneumatic springs 2, Fig. 1, and automatic height control of the frame 1 by means of links 6, 7, 8 which rotate the stems of control valves 4, a control 10 is provided which rotates the body of the control valves to cause raising or lowering of the frame 1 relative to axles 3 by the springs 2. The control 10 causes compressed air from a reservoir 9 to be supplied to one side or the other of a piston 12 which rotates the valve body 4 through links 13, 14. The link 13 is returned to its inoperative position by a spring 15 which bears on a flat face 17. The face 17 is disposed off-centre in relation to the shaft 14 so that approximately equal restoring forces are obtained from the spring 16. The lever 13 may be replaced by a T-shaped lever with rollers at the ends of the cross-piece against which the arms of a U-shaped spring bear. The control 10 may be used to raise and lower the frame for loading and unloading containers, or, in the case of semi-trailer vehicles for coupling and uncoupling the trailer.

Title: Axial-flow blower
IPC: F04D29/54
Filed: 1963-10-02
Abstract: 1,005,139. Axial-flow blowers. T. HELMBOLD. Oct. 2, 1963 [Oct. 16, 1962], No. 38746/63. Addition to 992,266. Heading F1C. In an axial-flow blower with a rotor having a shroud ring 7 extending in both axial directions a substantial distance beyond the rotor blades, one end of an intake nozzle 5 extends into the shroud ring. Thus an annular gap 10 is formed which together with a gap 8 permits a vortex flow across the ring 7. Additionally, a vortex flow across the hub 11 is permitted by passages in the hub and a gap 12 formed between the hub and a stationary cap 3 carrying the rotor mounting and drive means. In multi-stage blowers the cap may project into the hub and air may be sucked away from one of the upstream stages. The vortices promote a diffuser action at the blower delivery. In an alternative embodiment (not shown), the mounting and drive means are arranged downstream of the rotor, and the rotor hub is closed at its upstream end by a hemispherical part, thus no vortext occurs at the hub. Further, the upstream end of the blower outer casing curves outwardly parallel to the mouth of the intake nozzle and provides a passage therebetween for a second vortex at the outer casing, between the blower delivery and the suction side of the nozzle.

Title: Tyre air pressure detection and indicating device
Inventor: JOHNSEN E C
IPC: B60C23/04
Filed: 1970-08-12
Abstract: 1294212 Tyre deflation indicators ELTICO MFG Ltd 12 Aug 1970 [12 Aug 1969] 38921/70 Heading B7C [Also in Division G1] A tyre deflation detection device comprises an inductive sensor, means carried in the tyre for modifying the reactance of the inductive sensor upon a preselected amount of tyre deflation, and means responsive to the change of reactance for indicating said deflation. The inductive sensor S is secured to the wheel mounting to extend transversely of the tyre tread and comprises a wire loop of turns of wire 2 in a copper tubular ring 4 embedded in a plastics case 6, the loop being connected to the oscillatory part of a detecting and indicating circuit (Fig. 10, not shown). Within the tyre T, contacting the surface beneath the tread, is a plastics foam ring 8 having a flexible impervious skin 10 and containing ferromagnetic arcuate segments 12. When the tyre is inflated, as shown in Fig. 4, the ring 8 is collapsed against the tyre and the segments 12 lie within the magnetic field F associated with sensor S. On deflation the ring 8 expands moving the segments 12 away from the field F to modify the self inductance and hence reactance of the sensor, which causes a reduction in the amplitude of the oscillations and a lower output of a transistor (Q1) with the result that the output of the amplifier circuit is insufficient to energize a relay (R) and a lamp 24 and buzzer 22 of the indicating means are operated. One sensor can serve two adjacent pairs of twin wheels and a plurality of sensors can be connected to one circuit; alternatively an individual sensor, circuit and indicating means can be used for each tyre. When fitted to a tyre with an inner tube (14, Fig. 5) the ring 8 is positioned between the tube and the tyre cover and the skin 10 can be omitted.

Title: Improvements in the cracking of hydrocarbons
IPC: B01J8/24
Filed: 1956-12-21
Abstract: <PICT:0799289/IV (b)/1> In a process for the production of gaseous olefines by cracking gaseous and/or liquid hydrocarbons in a fluidized bed of granular inert or carbonaceous solid at 630-850 DEG C. with or without the addition of steam and/or free - oxygen - containing gases, the gaseous and/or vaporous reaction products immediately above the fluidized bed are enriched with pulverent or granular inert or carbonaceous solid so that the space above the fluidized bed contains 0.4-40 kg. of solid per cubic metre at about the same temperature as the fluidized bed, with or without the addition of further amounts of steam and/or free-oxygen-containing gas.  The enriching solids are preferably introduced into the fluidized bed and carried up by the ascending gases, they may then be separated and returned to the bed.  The solids serving as the fluidized bed can themselves be separated from gaseous and vaporous reaction products, and, if desired, absorbed reaction products at least partially separated or burned, and used to produce the suspension above the fluidized bed.  Both solids for the bed and the suspension are preferably oil coke formed in the reaction, but may also be sand, pumice or alumina.  In the Figure, the fluidized bed 2 of oil coke particles up to 4 mm. diameter is supported on a grate provided with fine slots.  A mixture of 400 kg. of superheated steam and 200 normal cubic metres of oxygen per hour enter through pipe 3, 500 kg./hr. of a mineral oil residue boiling above 320 DEG  C. enter through pipe 4, and 500 kg./hr. of recycle hydrocarbon products boiling above 250 DEG  C. enter through pipe 5 together with soot formed in the process.  The temperature is maintained at 720 DEG  C. and the supply of coke at 6 and withdrawal at 7 are adjusted so that 2 metric tons/hr. of solid are carried up through the annular chamber 8.  Solid is separated in cyclone 9 and flows back to the bed through pipe 10.  The free cross-section of the annular space 8 is preferably not more than one-fifth of that of the fluidized bed chamber.  The solids density in the space 8 is about 1.3 kg./cubic metre, and the temperature about the same as in the fluidized bed.  Each metric ton of fresh oil produces about 160 kg. of ethylene and 200 kg. of higher gaseous olefines.

Title: Improvements in or relating to the brewing of beer
Inventor: POLLOCK JAMES RICHARD ALLAN
IPC: A01K61/00
Filed: 1960-11-14
Abstract: In the production of beer, unfermented wort is added to a body of yeast in either wort or fermented wort, which is subjected to sufficient agitation to maintain the yeast evenly dispersed through the wort, the unfermented wort is added at such a rate that at the end of a predetermined time the body of fermenting wort is fermented to a desired degree of attenuation and at least a major part of the fermented wort is then separated from the yeast.  The agitation is stopped on attaining the desired degree of attenuation and the yeast is allowed to settle out for a predetermined time to form a yeast-rich bottom layer having approximately the yeast concentration of the initial yeast and wort mixture; the supernatant liquid is removed, leaving a volume of fermented wort and yeast equal to the initial quantity.  Yeast may be recovered from the supernatant liquid.  In preferred procedures, the initial body of yeast in wort has a yeast concentration in the range of from 25 to 300 grams (dry weight) per litre and is diluted by the addition of unfermented wort to from 25 to 100 times the initial volume.  An example is disclosed.

Abstract: 1,274,725. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 5 Aug., 1969 [6 Aug., 1968], No. 39126/69. Heading H1K. A P-type semi-conductor wafer of, e.g., monocrystalline silicon conventionally fabricated with 4 degrees orientation off the 111 axis towards the 110 axis, is lapped and chemically polished and ionically implanted (Fig. 1, not shown) by acceleration, focusing and deflecting of an ionic beam impinging on a target wafer maintained at 100-600 C. and subsequently annealed; the angle of incidence being controllable by rotation of the target and adjustment of ion beam energy and the area of implantation being controllable by focus and deflection, or masking the beam, or photoresist or metallic masking of the wafer surface. In the transistor (Fig. 2) comprising emitter, base, and collector regions 61, 62, 63, a constant impurity concentration 181 along a perpendicular to the surface bisecting, e.g., the emitter region with a steep termination gradient 182 at a predetermined depth (Fig. 4) is obtainable by successively ionically implanting regions 180 of the same impurity type at different depths by stepping the bombardment energy for each region, starting from a surface concentration 183 not limited by the impurity solubility in the substrate, and the terminal gradient 182 may be steepened by combination of two successive ionic implants for the deepest region 180 at which the steepest gradient is required; a first electrically inactive impurity, e.g., helium or other inert gas, is implanted to form distribution profile 166 of the substrate (Fig. 5) and second electrically active impurity e.g. phosphorus or arsenic, is then implanted into the same region in a narrower distribution profile having a higher peak impurity density and a reduction of the emitter capacitance is produced. Similarly, the required base width may be reduced by implanting the base region with a steep impurity gradient proximate to the base-emitter junctions.
