Title: Improvements in and relating to the treatment of coffee beans
IPC: A23F5/12
Filed: 1933-02-22
Abstract: Roasted coffee beans are subjected to a mechanical pressure to break up the beans and reduce the particles to thin flakes of substantially uniform thickness.  By this means the coffee components are rendered practically uniformly accessible to the extracting liquid and the coffee gas quickly expelled from the coffee cells without loss of flavour.  For this purpose the coffee may be roasted, broken and passed between rollers, preferably while still hot.  The rollers may be heated.  The product is coffee in the form of thin flakes.

Inventor: HOWLETT REX RICHARD
IPC: A01D34/42
Filed: 1966-03-04
Abstract: 1,157,627. Mowers. WILKINSON SWORD Ltd. 20 June, 1966 [4 March, 1966], No. 5410/68. Divided out of 1,157,626. Heading A1F. A power-driven machine for cutting grass and like vegetable matter comprises rotatable cutter means mounted so as to be upwardly movable relative to the remainder of the machine and control means attached to the cutter means and operative to raise the cutter means in response to an increase of the cutting torque exerted on the cutter means when rotating at constant speed. As shown rotary blades 9 are carried by a threaded nut 8 which engages a multi-start thread 7 on the vertical drive shaft 5 of an electric motor or internal combustion engine. A compression spring 10 acts between a flange 6 on shaft 5 and the nut 8, the force exerted by spring 10 being such that under normal conditions nut 8 is maintained in its lowest position which is determined by adjustable stop means 11. If the blades 9 encounter thick or long grass the torque executed on the blades 9 increases to overcome the force of spring 10 causing nut 8 to rise up the shaft. The multi-start thread 7 may be replaced by a helical groove in which case nut 8 carries an inwardly directed pin adapted to engage the groove. A flexible rubber cover 15 may be provided.

IPC: G05D13/00
Filed: 1928-02-21
Abstract: 286,296. Machine-Fabriek Geb. Stork & Co. March 4, 1927, [Convention date]. Fluid governors.-In a hydraulic valve-gear for fluid-pressure engines, the liquid is brought under constant pressure by a pump and is circulated in closed circuits either through a rotary distributor which controls the supply to the valve-pistons and then through vents in the piston or passages in spring-controlled liquidactuated valves in the valve cylinders or in closed circuits through bye-passes. In the apparatus, Fig. 4, fluid is drawn from the reservoir 1 by a pump 3 and is distributed by a rotary auxiliary valve 5 to the servomotor 7, the spring-loaded piston of which is provided with a leak 17. A valve-controlled bye-pass 10 is connected to the delivery pipe 4 and to the return pipe in front of a reducing-valve 8. The valve casing has an annular passage 20 connected to the pump supply and has ports 21 connected to recesses 22 in the casing and with the valve servomotor. A slidable ported sleeve 23 for adjustment and reversing is arranged between the valve 5 and the casing. The sleeve is controlled by a liquid-pressure governor. Liquid-pressure supplied by a gear-wheel pump driven by the engine acts upon a spring-controlled piston 47 connected to the spindle of the sleeve 23. The controlling- pressure may be adjusted by a needle valve in the delivery pipe. The leak 17 may be dispensed with when a valve 36 is used. In a modification, the liquid-pressure from the gearwheel pump acts upon the annular end of the sleeve 23 against the resistance of a spring.

Title: Improved lubricants adapted to soften carbon depositst in internal combustion engines
IPC: C10M135/12
Filed: 1942-04-29
Abstract: Oil-soluble saturated alicyclic alcohols having from 16 to 30 carbon atoms in the molecule are produced by condensing lower aliphatic ketones such as acetone or methyl ethyl ketone to form tricyclic unsaturated ketones and hydrogenating the latter to the corresponding alcohols.  Thus, a C18 alicyclic alcohol is produced by agitating acetone in aqueous potassium hydroxide at 170 DEG  C. and a pressure of 300 lbs. per sq. in. to form an unsaturated polycyclic ketone of the formula <FORM:0570951/IV/1> which is then hydrogenated to the corresponding saturated hydroxy derivative.  Many organic acids are specified as suitable for forming esters of such alcohols; esters of inorganic acids such as phosphorous, phosphoric, and thio-phosphoric acids and metal salts of polybasic organic acid esters are also included. Preferred esters are allophanic and thio-allophanic esters, <FORM:0570951/IV/2> where R1 is the saturated alicyclic radicle, X is oxygen or sulphur, and R2, R3 are hydrocarbon radicles or preferably hydrogen.  These may be prepared, for example, by reacting 1 mol. of the alcohol with 2 mols. of carbamyl chloride in benzene solution or by reacting 1 mol. of the chlorcarbonic ester with 2 mols. of urea or thiourea, or by passing cyanic acid vapours into the anhydrous alcohols, or by the reaction of carbamic esters or urethanes or thiourethanes with urea chloride. A thiophosphate derivative of the C18 alcohol may be prepared by reacting it with phosphorus pentasulphide, and the calcium salt of this body may be made by mixing it first with alcohol containing sodium ethylate and then with an alcohol solution of calcium chloride.  The ester salts of other alkaline earth metals and of Zn, Al, or Li are also referred to.  In another example, a naphthene allophanate is prepared by reacting petroleum naphthenic acid with carbamyl chloride.  The products are used in the manufacture of lubricants.

Abstract: 572,200. Machines for needling fibrous batts. UNSWORTH. T. A. April 12, 1943, No. 5832. Convention date, Sept. 18, 1942. [Class 42 (ii)] A machine for needling a travelling fibrous batt A includes opposed sets of needles 35, means for advancing the batt between the sets of needles, means for reciprocating the needle into and out of the batt and means for guiding the reciprocating movement so that when the needles are inserted into the batt and when being withdrawn therefrom they will be moved also in the direction of advancement of the batt. The batt A is brought to the needling machine by a conveyer apron 47 and may be treated by water &c. sprays from nozzles 55, 56 on its way through feeding rollers 48, 50 to adjustable racks 51, 52 comprising spaced bars 51b, 52b between which the needles operate. The needles 35 are carried by beams 33, 34 and are operated by adjustable cranks and connecting rods 25, 27, pivoting about bolts 37 linked to the machine frame by adjustable links 40, the cranks &c. being driven by a motor 70. Needles 65 carried by levers 67 pivoted at 68 and operated by connecting rods 69 remove any fibres which may cling to the lower set of needles 35. The arrangement of the needle linkages is such that whilst the needles 35 enter, pass through and withdraw from the batt they are moved with the batt at substantially the same speed, but when completely retracted from the batt they are moved in the opposite direction, the interlaced fibres moving finally from off the needle hooks due to the motion of the batt. The batt may comprise outer layers of softer and firmer fibres and the needling may be effected by pusher needles with barbs or fish-tail ends. From the batt-supporting plate 78, the needled batt is delivered by rollers 57, 58.

Abstract: 509,796. Sulphur-containing condensation products. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). Feb. 25, 1938, No. 6031. [Class 2 (iii)] Condensation products are prepared by heating allyl chloride with an alkali, ammonium or alkaline earth polysulphide at 50‹ to 150‹C., e.g. by boiling under reflex or heating in a closed vessel under pressure. Viscous products are first formed, which may be further heated to yield rubber-like products. The rubber-like products may be mixed with fillers, and may be vulcanized after the addition of sulphur. In an example, sodium sulphide is fused with sulphur, water and methanol are added, and allyl chloride is added while stirring and heating under reflux. The water, alcohol and small amounts of an oil are distilled off, leaving a viscous reaction product. Common salt is added to the distillate, and the separated oil added to the viscous reaction product. Water is then added to the mixture and the heating continued, upon which a rubber-like brown mass is obtained which is stable to organic solvents and oils and is suitable for the preparation of shaped articles. According to the Provisional Specification, allphatic halogenhydrocarbons containing only one reactive halogen-atom and one or more double linkages in general may be employed.
