Filed: 1948-04-28
Abstract: 643,821. Hop-picking machines. STEVENS, A. H. (Clemens Horst Co., E.). April 28, 1948, No. 11642. [Classes 6(iii) and 58] A hop-picking machine for removing hops from bines, in situ, comprises a pair of picking belts 17 which engage opposite sides of a row of bines as the machine advances along the row, the bines being simultaneously pulled downwardly by a roller J which rolls over the hop-roots. The picking belts include cross-bars 18 carrying wire fingers 19, and are mounted on sprockets 15, 58, driven by an engine 32 throughbevel gears 40, 45, 46 and beltdrives 56, 59, Fig. 4. The upper sprockets are mounted on brackets 20 movable horizontally to vary the vertical angle between the belts. The lower sprockets are mounted on longitudinal bars 7 pivoted at 6 to a cross-member 3 and movable horizontally to vary the angle between the planes of the belts and the central vertical plane of the machine. Longitudinal frame members 2 are flared outwardly (Fig. 3) at their front ends 4 to form guide surfaces for the bine stems. Rubber flaps covering the members 2 serve both to grip the bine stems and to deflect the plucked hops laterally on to conveyer belts 22 which transport them to an elevator 25 discharging through a shoot 29 to sacks on the rear platform 30. The machine is supported on the centrally-mounted roller J and on rear caster wheels 65 and is pushed by a tractor.

Abstract: 1,017,701. Push-button tuning mechanisms. R. HOPT. March 25, 1963 [April 9,.1962], No. 11679/63: Heading H3Q. In a push-button tuner the ends of the pushbuttons act with a leverage on a rotatable frame in order to convert the sliding movement of the push-buttons into a rotary movement for adjusting an associated tuner unit. The front ends 1 of push-buttons, when depressed, engage a shaft 2 which forms part of a frame, including a toothed segment wheel 3, connecting rod 4 and side part 5. This frame is rotatable about balls 7, 13 of bearing sleeves 9, 12 respectively and is arranged in its starting position such that the line between shaft 2 and the rotary axis of the frame is perpendicular to the direction of displacement of the pushbutton. On depression of the appropriate push-button the whole frame moves in an anticlockwise direction and the shaft 2 rotates on the forward end face of the end of the pushbutton substantially without friction. The balls 7, 13 may be replaced by a shaft rigidly mounted in housing walls 10, 11 on which the frame is rotatably mounted. An adjustable stop 17, Fig. 1 (not shown), is also fastened to the wall 10 of the casing, against which stop the frame 2, 3, 4, 5 is returned to under the action of a spring when the push-buttons are released.

Abstract: 513,459. Elastic-fluid turbines. BECHARD, E. April 19, 1938. No. 11829. Convention date, April 16, 1937. [Class 110(iii)] [Also in Group XIII] In a heat engine comprising a turbine 4 and a rotary boiler mounted on a common shaft 1, the working fluid is admitted to the boiler through the shaft and during vaporisation flows first centrifugally and then centripetally through dish-shaped chambers 5, 6. Hot gases supplied by burners 9 are caused to sweep the chambers by baffle plates 11. Adjustable fuel and air-inlet ports are provided in the casing 10 and baflles 11. In a modification, the chambers 5, 6 are replaced by nests of tubes having the same external contour. In one construction, shown in the upper half of Fig. 4, the tubes 12, 14 radiate from a drum 7 to a manifold 13 and in another construction shown in the lower-half of Fig. 4, U-tubes are used. Any of these constructions may be combined in one boiler. The casing 10 may be made rotatable to bring the combustion gases into contact with the tubes or chambers. A piston device for starting the engine under load, may be incorporated. The working fluid may be water or mercury. The Specification as open to inspection under Sect. 91 comprises also the use of a cylindrical or conical boiler, Fig. 6 (Cancelled), in which the combustion gases circulate either over the surface of the generator as shown in the upper half of Fig. 6 (Cancelled), or through passage b between the generator and a crown 18 attached to the generator by tubes 19, as shown in the lower half of Fig. 6 (Cancelled). In another modification the gases circulate in tubes, parallel or inclined to the shaft passing through the boiler. In a further modification, the turbine 4 is replaced by a piston machine. The engine may also be used as a condenser or cooler by causing the gases to be cooled to circulate inside, and the cooling fluid outside, the boiler. This subject-matter does not appear in the Specification as accepted.

Title: Lubricating grease compositions
Filed: 1956-04-20
Abstract: A lubricating grease composition comprises a mineral lubricating oil of viscosity 70-150 S.S.U. at 210 DEG  F. and at least 70 viscosity index gelled with a lithium soap of an hydroxy fatty acid and an alkali, or alkaline earth, metal naphthenate. The mineral oil may be a single oil or a blend which produces the above viscosity and viscosity index characteristics, preferably a blend of a distillate fraction with a Bright Stock.  The hydroxy fatty acids are especially those containing between 10 and 36 carbon atoms, most practically those from hydrogenated castor oil or the catalytic oxidation of hydrocarbon oil waxes.  Examples are 9-, 10-, 11-, and 12-hydroxy stearic, 10- and 15-hydroxy palmitic, hydroxy myristic, hydroxy behenic, 5,6-, 6,7-, 7,8-, 8,11-, 9,10-, and 10,11-dihydroxystearic and 2,11-dihydroxy palmitic acids. Preferred alkali, or alkaline earth, metal naphthenates are calcium, barium, magnesium, sodium, lithium, and potassium naphthenates.  Naphthenic acids include the alicyclic carboxylic acids such as the cyclopentane- and cyclohexane-carboxylic acids, and may be modified by substituted groups such as aryl and/or alkyl radicals, unsaturated straight and/or branched-chain radicals, substituted alkyl, aryl, and/or alkene radicals and the saturated cyclic carboxylic acids may also be modified, the addition of side groups comprising saturated cyclic hydrocarbons or by condensation to form two or more chemically-fused saturated hydrocarbons.  Examples are the naphthenic acids extractable from petroleum oils and other natural sources, e.g. abietic acid from pine rosin.  Optional ingredients are the esters of aliphatic carboxylic acids and polyalkylene glycols, alkaline earth metal hydrocarbon sulphonates, antioxidants such as diaryl amines, e.g. phenyl-alpha-naphthyl-amine and 1-salicylal amino guanidine mono-oleate.  In examples lithium 12-hydroxy stearate and lithium and calcium naphthenate are used with and without the addition of poly-(oxyethylene)-glycol mono-oleate, calcium petroleum sulphonates, phenyl alpha-naphthylamine and 1-salicylal amino guanidine mono-oleate.  Specification 818,328 is referred to.

Regulating compression; valves, arrangement of.-In the steam generator described in the parent Specification, the steam circulation pump and the feed pump are driven by the same engine, the delivery of the pumps being regulated by varying the speed of the engine. The delivery of the feed pump 1, Fig. 2, driven with the steam circulation pump 2 by an engine 3 is independently controlled by a regulating valve 7 in a feed return pipe 6, or by varying the stroke of the pump. Separately driven auxiliary pumps are used for starting the generation of steam and for maintaining the generation when the main engines are not running: The delivery of the pumps may be controlled from the valve gear of the main engine. The steam circulation pump may be double-acting and may have a piston valve 32, Fig. 6, with little or negative lap, controlling the admission and discharge of steam. Steam from the inlet port 33 passes around the piston valve to the cylinder ports 31a, 30<a> in turn. Steam delivered from the cylinder through the lower port 31a passes through the piston valve to the outlet port 34. A cooling coil 38 connected to the cylinder and valve casing supplies condensed steam for lubricating purposes. The phase displacement of the piston valve is varied by moving axially a helically grooved sleeve 41 in the eccentric 42.
