Title: Improvements in or relating to the stabilisation of unsaturated ketones
IPC: C07C45/86
Filed: 1947-08-05
Abstract: Unsaturated ketones which are normally liquid are stabilized against colour change by incorporating therein a minor proportion of a secondary amine.  Preferred amines are morpholine and aliphatic mono-amines in which the nitrogen atom is attached to a secondary carbon atom in each of the alkyl groups, e.g. di-sec-butylamine and di-isopropylamine, but many others are specified as suitable; the amount of amine used is normally about 0.01 to 3 per cent by weight. The stabilization is effective even in the presence of iron.  The amine may be added to the ketone as such, or added to only a portion thereof and the resulting mixture added to the remaining ketone in an amount sufficient to attain the desired concentration.  The pure ketone may be recovered from the stabilized mixture by suitable means, e.g. distillation, fractionation, adsorption and solvent extraction. The process is particularly adapted to ketones having an unsaturated group of at least 3 carbon atoms, such group including an unsaturated tertiary carbon atom, especially when the latter is in the beta position with respect to the carbonyl group.  Suitable ketones are listed, both those belonging to these two types and others.  Tables are given showing the colour developed in mesityl oxide both with and without a secondary amine as stabilizer.

Abstract: 225,601. Johnson, J. Y., (Lusse, J., and Lusse, R., (trading as Lusse Bros.)). Aug. 22, 1923. Controlling different functions by same handle or lever.-Relates to vehicles mainly for amusement of the kind in which a controlling and steering lever is provided, the driving, gear being controlled by backward and forward movement of the lever and steering being effected by rotary movement of the lever. In the construction shown the vehicle is carried on a steering wheel 6 and a driving wheel 2, a continuously-driven electric motor 33 driving the wheel 2 through friction disc change-speed and reversing gear constituted by pairs of rollers 14, 15. The, rollers are slid along their shafts to vary the speed or to reverse the vehicle by backward and forward movement of the steering lever 11, this lever being pivoted at 12 and connected to sleeves 16 carrying the rollers bv a lever 45, a member 43a, and a cross-head 41. The steering-wheel 6 rotates in a fork 8 carried by the steering-shaft 9 which can be rotated bv the handle 10 in the sleeve 11. The steering lever is normally retained in the neutral position in which both sets of rollers are free from the wheel 2 by springs 48, 50. The rear ends of the shafts 17 are carried in bearing blocks 18 pressed inwards by springs 24 so that the pressure of the driving rollers on the wheel 2 is limited to that due to the springs and the rollers can slip on thewheel if the vehicle is stopped by an obstacle.

Filed: 1950-08-29
Abstract: 688,862. Gill drawing frames. DOTTI, E. L. Aug. 29, 1950, No. 21329/50. Addition to 642,647. Class 120(i) A modification of the drawing frame claimed in the parent Specification comprises guide members consisting of fingers 1 secured to the ends of the comb bars 2 and co-operating with guide ways 4 and 5 to control the interposing of the combs between the rods 10. During operation of the apparatus shown, driven conveyer chains 3 and bars 2, combs 7 and bevel-pointed fingers 1 pivotally connected thereto, Fig. 2, move interposed between the rods 10 and driving chains 11 throughout a guided horizontal upper run, (B) to (A) of the chains. At the end (A) lower chamfered parts 1<SP>11</SP> of the fingers 1 contact guide ways 5 so that the fingers incline and compel the combs 7 to assume an inclination in the direction of movement of the chains which is maintained until the parts 1<SP>11</SP> contact the guide ways 4 and hence compel the combs 7 to assume a vertical position as they pass between the rods 10 in the zone (B), after which the parts 1<SP>11</SP> move out of contact with the guide ways 4: also in the zone (A), since guide rails 9 of the chains 3 are shorter than guide rails 14 for the chains 11 the combs 7 descend before the rods 10 which latter thus "sweep" the fibrous material from the combs.

Abstract: 1,007,300. Trailer brakes operated by backward pressure of tractor. H. EBERHARDT, [trading as PEKA-FAHRZEUGBAU-KOMMANDITGESELLSCHAFT]. May 25, 1964 [May 28, 1963; April 27, 1964], No. 21470/64. Heading F2E. A reversing lock for use with overrun brakes on vehicle trailers comprises means responsive to the selection and disconnection of reverse gear on the tractor to lock and unlock respectively the overrun brake operating mechanism. In one embodiment, Fig. 1, solenoid 4 is energized and de-energized in response to the closing and opening of a switch K positioned for automatic operation by the gear lever S on the tractor vehicle, when reverse gear is engaged and disengaged, respectively. Energization of the solenoid pivots a lever 3 about a pivot 6 on trailer element 2 of the overrun brake actuating mechanism to cause its forward end to be placed in the path of an abutment 7 on element 1 of the brake actuating mechanism which is secured to the tractor, thus preventing operation of the mechanism. A spring 9 pulls the lever to its inoperative position when the switch opens. An abutment may be positioned adjacent the rear end of lever 3 to protect the pivot 6. In Figs. 5 and 6, the solenoid S is contained in a casing 140 removable from a pin 30 secured either direct or via a mounting plate to the element 70 on the trailer, the armature 150 of the solenoid being connected to a latch 40 pivoted to the casing 140 so that on energization of the solenoid the latch is placed in the path of an abutment 60 secured to element 50 on the tractor. An adjustable screw 110 limits rearward movement of the body 100 of the solenoid. A spring 120 urges the solenoid body against the screw, and a spring plate 310, Fig. 8, acts as a resilient slideway for the adjusting movement of the solenoid, plate 310 having bent out portions 320 and 330 engaging the walls of the casing 140.

Title: Improvements in and relating to the manufacture of cellulose ethers
IPC: C08B11/16
Filed: 1930-07-23
Abstract: Aralkyl cellulose ethers, and particularly benzyl cellulose, are prepared by mixing moist alkali cellulose with at least the theoretical quantity of aralkylating agent required, and thereafter adding solid caustic alkali.  The mixing of the moist alkali cellulose and aralkylating agent is preferably carried out with constant stirring and cooling; solid caustic alkali is then added and the materials heated to 80-120 DEG  C. under ordinary or increased pressure.  An excess of benzyl chloride is preferably used, for example from 1,4 to 3 times the theoretical amount required to convert the cellulose into dibenzyl ether.  The viscosity of the product varies with the total amount of caustic alkali used, and good film-forming products free from degraded ethers may be produced. Specification 327,714, [Class 2 (ii), Cellulose &c.], is referred to. Reference has been directed by the Comptroller to Specifications p 12854/12 and 6035/13, [both in Class 2 (ii), Cellulose &c.].
