Patent GB-692679-A (GB)
Title: Improvements in the production of unsaturated organic compounds
IPC: C07C45/69
Filed: 1951-09-04
Abstract: Unsaturated organic compounds are produced by reacting a mono-olefine having a CH3-or CH2- group adjacent to the double linkage at temperatures above 150 DEG  C. and under superatmospheric pressure with an ethylene derivative which is substituted only on one carbon atom of the ethylene group by a carbonyl, carboxylic, ester, amide or nitrile group and in which an alkyl group may be attached to either carbon atom.  Suitable mono-olefines are propylene, hexylene, isobutylene and phenylpropylene and suitable substituted ethylenes are acrolein, crotonaldehyde, vinyl methyl ketone, acrylic and methacrylic acids with their esters, amides and nitriles.  In the case of acrylic acid the reaction proceeds as follows: H2C=C(CH3).CH3+H2C= CH.COOH ---> H2C=C(CH3)-CH2.CH2. CH2. COOH.  It is preferable to use solvents for the reaction, e.g. ether, benzene, paraffin or stearic acid.  A small amount of a polymerization-inhibiting agent, e.g. hydroquinine, may be used and it is desirable to use vessels which are free from iron.  In the examples: (a) acrylic acid reacts with propylene to give hexenic (1)-acid (6); (b) acrylic acid reacts with isobutylene to give 2-methyl-hexenic (1)-acid (6); (c) acrylic acid reacts with 1-phenyl-propylene-(1) to give 1-phenyl-hexenic (1)-acid (6); (d) acrylonitrile reacts with isobutylene to give 2-methyl-(5)-cyano-pentene (1); (e) acrylic acid ethyl ester reacts with isobutylene to give the ethyl ester of 2-methyl-hexenic (1)-acid (6); and (f) vinyl methyl ketone reacts with isobutylene to give 2-methyl-heptene (1)-one (6).

[Class 107] A vibrating-apparatus for consolidating concrete roads comprises a plate A carrying the vibrators 2 and supported by two supports B adapted to roll upon cross-pieces C extending transversely across the road, the supports being so constructed that their rollers 10 can readily be turned through 90‹ to enable the apparatus to be moved along the side of the road for work upon the next section thereof. Each support may consist of a frame 6 carrying four upright hollow columns 11 which form sockets for pins 12 extending from plates 13. These plates carry the bearings for a shaft 4 upon which are wound the supporting cables 5 of the plate A ; the plate is raised or lowered by means of hand wheels 14 mounted on the shaft. The apparatus may be moved across the road by means of a hand wheel 16 which is mounted on a shaft 17 geared to the rollers 10. To wheel the apparatus to the next concrete section, the plates 13 and associated parts are lifted bodily to disengage the pins 12 from the sockets 11, the supports are turned through 90‹, and the plates are then lowered to re-engage the pins with the appropriate sockets. The cross-pieces C each consists of two iron pieces 19 and a supporting plate having a central rib 20a. The ends thereof rest upon the roadside and may be fitted, as shown in Fig. 5, with a roller 21 mounted on a lever 24 pivoted at 23 to a bracket 22. By manipulating the lever, the rollers are brought to bear against the ground thus raising the cross-pieces which can then be wheeled to the next section. In modifications, the cross-pieces are made in sections, either rigidly or pivotally interconnected, and adapted to rest directly or indirectly upon the road foundation or upon an adjacent section of the concrete covering.

Title: Tomography
IPC: A61B6/02
Filed: 1977-05-19
Abstract: The detector surface (2) which the X-rays strike after passing through the object (3) to be investigated is dimensioned so that it collects the fan-shaped X-ray beam emitted by the X-ray source (1) completely. The thickness of the fan-shaped beam is matched to the thickness of the disc-shaped layer of the object (3) to be investigated, a tomogram being produced in each case of said layer. During the irradiation, the object (3) is rotated with respect to the X-ray source (1) and the detector surface (2), in particular about an axis which extends perpendicularly to the plane of the fan of rays and is located on one of the two diverging side edges of the fan of rays. During the irradiation, the object is then rotated through 360 DEG C. The device makes it possible to use a comparatively small detector surface, which has various advantages, such as comparatively cheap construction, low radiation dosage and high resolution. <IMAGE>

Title: Improvement in valves for gas and liquid fuel burners
IPC: F24C3/12
Filed: 1922-08-03
Abstract: 207,585. Kennedy, W. J. Aug. 3, 1922. Valves actuated indirectly by the agency of a cooking vessel when placed on a stove include a spring-controlled movable valve operating member in the valve casing adapted to be swung into the valve opening position by a horizontally movable arm projecting above the stove. The valve C is connected to an arm E which slides in a cylinder G operated by a screwed spindle H, the sliding movement being governed by the stop J. A horizontally movable arm G projects over the stove and is connected to a spindle R provided with an eccentric projection S, which, when the arm Q is moved by the cooking utensil, bears against the upper end of a spring M to free the arm E so that the spring D releases the gas valve B from its seating C. If the arm Q is inadvertently fixed, the gas valve C is opened by the movement of the screwed spindle H. The spring M is stronger than the spring D so that in the normal position of the arm Q the valve C is closed. In a modification, the gas valve orifice is regulated by a screwed sleeve. A pilot jet ignites the gas issuing from the burner.

Patent GB-602271-A (GB)
Title: A process for separating non-aromatic hydrocarbons from hydrocarbon mixtures
Filed: 1945-08-23
Abstract: A liquid hydrocarbon mixture, having an initial boiling point above about 200 DEG  C. and containing at least 5 per cent by volume of a normally solid wax dissolved therein, is mixed with at least an equal volume of a polar solvent which is a selective solvent for aromatic hydrocarbons and the mixture is cooled to a temperature at least as low as that below which the viscosity of the mixture begins to decrease again, the resultant solid material comprising the wax and substantially all of the non-aromatic hydrocarbons being then separated from the remaining liquid.  The separated solid material may be treated with a second polar solvent at a temperature higher than that employed in the first cooling but below about 0 DEG  C. to produce a liquid phase comprising the non-aromatic hydrocarbons and a solid wax phase.  In this way the normally liquid non-aromatic hydrocarbons may be obtained from a liquid hydrocarbon mixture containing both aromatic and non-aromatic hydrocarbons while, if desired, the solid wax phase which is isolated may be separated into amorphous and crystalline waxes by a similar treatment at still higher temperatures.  The liquid hydrocarbon mixture used as starting material may be any hydrocarbon mixture heavier than kerosene, particularly mineral lubricating oil.  In the latter case the liquid phase comprising the non-aromatic hydrocarbons which is obtained is particularly useful as a high viscosity index lubricating oil.  If the oil contains too much wax it must be partially de-waxed before the treatment, while if it has insufficient wax some must be added. Any crystalline wax may be added for this purpose, even a vegetable or animal wax of the ester type.  The oil is preferably de-asphaltized before the treatment although hard asphalts which remain in the wax when chilled may be tolerated or even may be added as a filter aid.  Suitable polar solvents are chlorinated hydrocarbons such as methyl chloride, ethylene dichloride and chloroform; alcohols such as isopropyl alcohol and secondary butyl alcohol; ketones such as acetone, methyl ethyl ketone, methyl n- and isopropyl ketone, di-isopropyl ketone and methyl isobutyl ketone; esters such as methyl and ethyl formates, acetates and propionates. Methyl ethyl ketone, may be used in admixture with an aromatic hydrocarbon such as benzene, toluene or xylenes while methyl isobutyl ketone may be used in admixture with acetone or methyl ethyl ketone. The same or different solvents may be used in each separation and chilling operation as desired. Specification 505,740 and French Specification 805,512 are referred to.

Abstract: 740,363. Clutches. LEYLAND MOTORS, Ltd. Aug. 27, 1953 [Aug. 27, 1952], No. 21586/52. Class 80(2) A pneumatically-actuated disc clutch 9, 10, 30, arranged in parallel with a fluid coupling 3, 4 in a motor-vehicle drive, is controlled by a centrifugally-operated valve with two heads 22, 23. At low speeds, a spring 24, together with pressure air entering the outer valve chamber 17 through passages 29, 16, 25. maintains valve head 22 closed and head 23 open, so that air behind a diaphragm 13 moving the clutch presser plate 10 passes through passages 15, 26 to the inner valve chamber 19 and escapes through passages 27, the clutch being disengaged. At a certain speed valve head 22 opens and head 23 closes, opening passage 26 to the outer valve chamber 17 and shutting it from the inner chamber 19, so that the clutch engages. The clutch disengages at a lower speed, due to head 23 being smaller than head 22,
