Title: Improved plastic or mouldable material and method of producing the same
IPC: C08L97/02
Filed: 1943-07-17
Abstract: A plastic or mouldable material is prepared by treating vegetable matter, such as wood, sawdust, chippings, shavings, &c., with a caustic alkali so as to produce a pulp having a self-binding property, removing the alkali by washing or acidification, treating with acid, washing and then applying heat and pressure in the wet or dry state to bind the mass together, a waterproofing material being added at any stage.  The caustic alkali, preferably sodium hydroxide, is of 2 1/2 to 20 per cent strength, and the treatment is carried out at temperatures between 0 DEG  and 115 DEG  C. for a period varying proportionately from 48 hours to 5 minutes.  The alkali is removed by washing and, if desired, by treatment with an acid, e.g. acetic, during or after washing, and the moulding and binding properties are improved by treating with acid, e.g. 5 per cent sulphuric, to hydrolyse the cellulose material.  A small percentage of wax, for example, 3 per cent of paraffin wax, is incorporated at any stage up to pressing, for waterproofing purposes, and pigments may also be added.  After washing free from acid, the mass is rolled or pressed in moulds in the wet or dry state at a pressure of from 1 to 3 tons per square inch and at a temperature of 150-160 DEG  C.ALSO:A plastic or mouldable material is prepared by treating vegetable matter, such as wood, sawdust, chippings, shavings, &c., with a caustic alkali so as to produce a pulp having a self-binding property, removing the alkali by washing or p  acidification, treating with acid, washing and the applying heat and pressure in the wet or dry state to bind the mass together, a waterproofing material being added at any stage.

Title: Improvements in or relating to cigarette making machines
IPC: A24C5/35
Filed: 1966-03-18
Abstract: 1,127,062. Cigarette making machines. SKODA OBOROVY PODNIK. 18 March, 1966 [20 March, 1965], No. 11963/66. Heading A2C. Cigarettes normally delivered from a cigarette making machine directly to a filter tip applying machine, may be diverted into a container should there be a stoppage of the filter tip supply, or the cigarettes may be fed from the container should there be a stoppage of the main cigarette supply. The cigaretes 2 are fed from a cigarette making machine 3 by an endless conveyer chain 1. The cigarettes pass under a sensing device 48 and container 19, normally kept closed as long as the senser 48 detects the presence of cigarettes, through the grooves of a roller 11, over the curved arm 10 of lever 7, and to conveyers 4 and 5 for application to filter tips. In the event of a breakdown of the machine supplying filter tips, a solenoid 9 is energized to operate the lever 7 in a clockwise direction so that the cigarettes are retained on the roller 11 by a guide 13. The cigarettes are delivered to an endless conveyer 15 and carried upwards to the entry to the container 19. The container 19 contains one or more, e.g. 2, surface indicating devices each comprising endless conveyers 38, bridge members 40 and level detectors 39, and rotatable about shafts 30 and 31 respectively. The conveyer 15 and the indicating devices are driven by gears and chains from a main drive shaft 52. The diverted cigarettes are delivered to the left-hand side of the container 19 by the first indicating device and, when a predetermined level has been reached, the detector 39 is operated. A further gear train on the shaft 30 is then clutched in and the whole of the indicating device rotates anti-clockwise about the shaft 30 until the detector 39 contacts a magnetic stop 28. Diverted cigarettes then travel over the bridge 40 to the second indicating device. When the right hand side of the container is full the detector 39 of the second indicating device is operated and a further clutch on the shaft 31 is operated to rotate the second indicating device and stop the cigarette machine. If, before this stage is reached, the fault in the filter feed machine is corrected, the solenoid 19 is de-energized, lever 7 returned to its normal position and the cigarettes no longer diverted. In this event the container 19 remains partially full. If a fault occurs in the cigarette making machine, lack of cigarettes is detected by the senser 48 and a solenoid 46 is energized. This retracts a pusher 43 from the outlet of the container 19 to allow cigarettes to be fed therefrom by the rollers 24 and 25 until the fault is corrected.

Abstract: 914,762. Radio-navigation. BENDIX CORPORATION. April 6, 1961 [April 7, 1960] No. 12420/61. Class 40 (7). The automatic pilot in an aircraft 10 (Fig. 1), is conditioned at a point E (defined either by a range signal from the transmitter 11, establishing the flight path A, B, or by the intersection of the latter path by the beam of an auxiliary transmitter 12 to put the aircraft into holding loop pattern comprising a constant rate turn until the point G is reached, then to fly along the straight path G, H for a predetermined time and at the point H to again effect a constant rate turn until point K is reached at which the aircraft flies along a beam captive path K, L and then along the beam A, B, the sequence being repeated if required when point E is again reached. The invention utilizes a known automatic pilot control system with the addition of means responsive to the arrival of the aircraft of point E to initiate the above described holding loop pattern, the constant rate turns being connected for the effects of cross winds and the straight paths being determined by thermal delay relay devices (Fig. 2, not shown). To avoid an unduly long beam capture path K, L when the loop is executed relatively close to the transmitter 11 the outbound flight path is made parallel to the bearing A, B so that at the end of the second constant rate turn the aircraft is again on bearing A, B (Figs. 3 and 4, not shown).

Title: Manufacture of 1-hydroxyaryloxy-3-alkoxy-2-propanols or-2-propanones
Filed: 1941-09-25
Abstract: 553,202. 1 - Hydroxyaryloxy - 3 alkoxy - 2 propanols. GEIGY AKT.-GES., J. R. Sept. 25, 1941, No. 12431. Convention date, Sept. 26, 1940. [Class 2 (iii)] 1 - Hydroxyaryloxy - 3 - alkoxy - 2 propanols are prepared by reacting an epihalogen hydrin with an alcohol which may contain a tertiary amino group to form the corresponding glycerine hydrinalkyl ether and then treating this compound in the presence of a base with a polyvalent phenol or a phenol derivative. Alternatively the polyvalent phenol with all its hydroxyl groups except one substituted by radicals capable of being split off easily, is first reacted with the epihalogen hydrin, and the epiaryline thus obtained reacted with an alcohol which may as before contain a tertiary amino group. The propanols obtained by either of the above alternatives may be oxidized to the corresponding propanone compounds by treatment with oxidizing agents known to be capable of converting secondary alcohols to ketones. The substitution of the hydroxyl group of the phenol which is necessary in the second alternative above is carried out preferably by the introduction of an acyl residue such as the benzyl, carbomethoxy and carbobenzyloxy radicals. The oxidation step may be carried out before these protecting groups are removed. The polyhydric phenols may if desired be substituted by other atoms or groups such as halogen, nitro, and carboxyalkyl groups. In examples (1) Glycerine chlorhydrin ethyl ether prepared by heating epichlorhydrin with alcohol is reacted with pyrocatechine in the presence of alcoholic potassium carbonate to give 1 - (2<SP>1</SP> - hydroxyphenoxy - 1<SP>1</SP>) - 3 ethoxy propanol - 2. (2) Glycerine chlorhydrin - allyl ether is treated as in example (1) to give 1 - o - hydroxyphenoxy - 3 - propenoxy - propanol. (3) Pyrocatechine is converted into its monobenzyl ether and then reacted in the presence of potassium hydroxide with epichlorhydirn to give o - benzyloxy - epiphenylene. This is then treated with diethylamino ethanol to give 1 - o - benzyloxyphenoxy - 3 - diethylaminoethyloxy - propanol 2. Acid hydrolysis with n - hydrochloric acid gives the free phenolic base. Other bases which may be used in place of diethylaminoethanol include methylpropylamino ethanol, methylisopropylamino ethanol, methylisobutylamino ethanol, and methyl tertiary butyl amino ethanol. Oxidation to the corresponding propanone is carried out by treatment with chromium trioxide in glacial acetic acid. (4) o - Benzyloxy - epiphenylene is reacted with N - hydroxy ethyl piperidine to give 1 - (2<SP>1</SP> - hydroxyphenoxy 1<SP>1</SP>) - 3 piperidethyloxy - propanol - 2. (5) o - Benzyloxy - epiphenylene is reacted with N - hydroxyethyl - morpholine as in example (4) to give 1 - (2<SP>1</SP> hydroxyphenoxy - 1<SP>1</SP>) - 3 - morpholinylethyloxy - propanol - 2. Specification 420,078 is referred to.
