[Classes 59 and 82 (ii).] Material such as sand and gravel is introduced into a rotating perforated drum in which it is subjected to the action of pulverizing means and is carried through the drum against a flow of water, the dirt overflowing at the feed end of the drum, the fine particles such as sand passing through the perforations into a hopper from which they are removed, and the larger particles such as gravel being discharged from the end of the drum remote from the feed end. The pulverizing means are situated at the feed end of the drum and consist of trailing members such as chains, balls, or rollers carried by one or more stationary members, for example, a bar or bars projecting through the feed opening of the drum. In the form shown, a rotating drum is formed of two chambers, an imperforate scrubbing chamber 1 preferably rubber lined, and a perforated screening chamber 1<a>, the drum being carried by spiders 3 and longitudinal channel bars 4, preferably T-shaped, which act as lifting members for the material passing through the drum. Material is fed into the scrubbing chamber through the feed opening in the end 6 by a shoot 10 and is acted on by the pulverizing means which comprise chains 8 which are attached to a bar 7 projecting through the feed opening and which trail on the inner surface of the chamber 1 which is preferably provided with a lining 9 of rubber, iron, or steel. Instead of chains, rollers or balls attached to the bar 7 by springs may be used. The pulverized material is carried along the drum by inclined blades 13 attached to the inner surface of the drum or to the longitudinal channel bars 4, or alternatively the drum may be inclined towards the discharge end, and water is supplied at the discharge end through a spray nozzle 14. Dirt is carried in suspension in the water and overflows through the feed opening, and the coarser material which reaches the discharge end of the drum is raised by perforated scoops 11 which pass through the water sprays from the nozzle 14 and discharge into a shoot 12 projecting through the discharge opening. Fine particles pass through the perforations in the screening chamber into a semi-circular tank 15 and are drawn up a shoot 16 by an endless scraper or bucket conveyer 17, the shoot and the perforated scrapers of the conveyer being preferably lined or faced with rubber. To prevent clogging of the perforations of the screening chamber, spray pipes 22 controlled by cocks 23 are provided above the drum.

Title: Improved process of refining hydrocarbons
IPC: C10G53/14
Filed: 1931-11-19
Abstract: Benzoles, petroleum spirits, or other hydrocarbons are purified to obtain motor fuels by treating the liquid or vapour with ozonized air, and then with diluted or concentrated sulphuric acid to which ferric chloride or sulphate is added before or during the treatment. Washing with soda lye and with water, and distillation may follow, and washing with soda lye may precede the sulphuric acid treatment. In one example, 200 cubic metres of air containing 1 per cent by volume of ozone are bubbled in 1 hr. p  through 1000 litres of cracked spirit containing 20 per cent by weight of ethylene hydrocarbons; the product is washed with soda lye of 1 per cent strength, treated twice with 50 litres of 70 per cent sulphuric acid containing ferric chloride solution, washed in turn with water, soda lye and water, and distilled up to 200 DEG  C. The acid may be re-used after filtering off the flakes of tarry matter.  Other examples specify respectively 60 per cent and concentrated acid.  The Specification as open to inspection under Sect. 91 describes purification by careful oxidation by an oxidizing fluid, e.g. ozonized air, followed by sulphuric acid treatment.  A salt of a trivalent cation, preferably ferric chloride or sulphate, or other product, e.g. an adsorbent or decolourizing earth, causing flocculation of the tarry impurities, may be mixed with the acid. Fuller's earth, Floridin, Bentonite, and bauxite are specified earths.  This subject-matter does not appear in the Specification as accepted.

Patent GB-410208-A (GB)
Title: Improvements in or relating to the production of unsaturated esters
IPC: C07C69/54
Filed: 1932-11-17
Abstract: Lower alkyl esters of a -alkylacrylic acids are manufactured by reacting a lower alkyl ester of an a -hydroxy-a -alkylpropionic acid with phosphorus oxychloride.  One molecular proportion of phosphorus oxychloride may be employed to every three molecular proportions of the hydroxy-ester, but larger yields are obtained by employing larger proportions of phosphorus oxychloride, e.g. about 1.5 molecular proportions to three of hydroxy-ester.  The reaction is advantageously facilitated by warming the reaction mixture under reflux, e.g. to boiling or to 100 DEG  C.  Moisture is excluded from the reaction mixture, e.g. by means of a calcium chloride tube between the reflux condenser and the atmosphere, whilst the condenser is preferably provided with a spray arrester to catch any liquid carried away by the hydrogen chloride evolved. The reaction is preferably performed in the presence of a small quantity of an anti-polymerization material, e.g. hydroquinone, sulphur or copper, which should also be present during the purification of the product. The reaction mixture may be worked up by distillation, with or without reduction of pressure, which may be continued until the temperature of the liquid approaches 200 DEG  C., the distillate being fractionated and the ester fraction purified by treatment with an alkali or alkali carbonate solution and then with water, followed by drying over anhydrous calcium chloride or sodium sulphate and redistillation under ordinary or reduced pressure.  Examples describe the manufacture of methyl methacrylate from methyl a -hydroxyisobutyrate.

Abstract: 1,034,958. Watches and clocks. FABRIQUES DES MONTRES ZENITH S.A. Aug.11, 1964 [Aug. 21,1963], No. 32614/64. Heading G3T. [Also in Division H3] A watch which includes a balance having a permanent magnet, the oscillation of which induce pulses in a control winding B1, Fig. 1 (not shown), which are amplified in transistors before being applied to a driving coil B2, comprises a first transistor T1 connected with a battery S through a resistance 1 and also to the winding B1 and a condenser 4, the condenser being charged by the battery through the resistance 1 and a further resistance 2 to a voltage such that during starting of the watch the transistor T1 operates as a class A amplifier, and a second transistor T2 which is connected to the driving coil B2, a resistance 2 and the transistor T1, the resistance 2 ensures that under starting conditions the transistor T2 also operates as a class A amplifier. The arrangement also provides that under normal operation of the watch the transistors T1 and T2 operate as class B amplifiers because the charge of the condenser 4 drops to a voltage lower than that of the threshold voltage of the transistor T1. A condenser 5 is connected with the transistor T1 to eliminate high frequency electric oscillations and a resistance 3 limits the current in the collector of the transistor T1. In a further circuit described the resistance 1 is connected with the collector of the transistor T2, and a variable resistance is connected in series with the coil B2.

Abstract: 903,777. Parachute and survival packs for airmen. G. Q. PARACHUTE CO. Ltd., GREGORY, J., and BASNETT, J. T. Dec. 23, 1960 [Sept. 25, 1959], No. 32662/59. Class 4. A parachute pack contains both parachute and survival equipment for an airman detachably secured to a seat in a position ready for connection at will to harness worn by the airman, the connection being effected quickly in an emergency but the equipment normally disconnected from the harness so that during normal flight only the harness is worn. The pack comprises a rectangular casing 10 curved transversely to fit the airman's back and positioned against the back of a chair 11 provided with a headrest 12 to which the pack is fastened by straps 13 and press-button carriers 14, the latter being also secured to the lift webs 15 of the parachute contained in the pack so that the airman is free to rise from the chair without the pack. The pack casing may comprise a fabric base stiffened by a wire frame and it is fitted with rear closure flaps 16 controlled by conventional locking cores with ripcord pins and with elastics 17 for opening the pack. The interior of the casing is divided into two compartments, one behind the other, the inner compartment containing the survival equipment and the outer one containing the parachute equipment, the two being separated by internal closure flaps controlled by conventional locking cones and rip cord pins with elastics for opening the flaps. The survival equipment may include an inflatable dinghy and an emergency supply of oxygen or inflating gas may be stowed in an inner compartment. Two flexible side wings 24 extend from the side edges of the pack casing and they are fitted at their ends with lugs 25 whereby the pack may be locked on the airman when desired. The flaps are adapted to support various control means including a manual over-ride cord handle 26 for releasing the closure flaps 16 of the pack, a speech-and-receive unit 27, battery 28 and aerial 29 and a valve (not shown) for dinghy inflation. The lift webs 15 connected to the parachute rigging lines extend out from the top of the pack for attachment to the press button carriers 14, their free ends being fitted with D-rings 30 for connection to snap hooks 31 on the front of the harness. Normally the parachute pack remains in position on the seat so that the airman is free to move about the aircraft unencumbered by the pack. In an emergency however it is only necessary for him to couple the wings 24 round his waist, connect the lift webs 15 by their rings 30 to hooks 31 and at the same time to connect fastening straps 13 to the leg straps 32 of the harness. The parachute may be released by operation of handle 26 or by a static line, but preferably it is released by a barometric device contained in the pack casing and armed by a static line.
