Title: Improved Speed Gear for Internal Combustion Engines.
Inventor: NEIGHBOUR ARTHUR GEORGE LLOYD
IPC: B62M25/00
Filed: 1916-07-18
Abstract: 105,173. Neighbour, A. G. L., and Michell, A. G. M. July 18, 1916. Driving-gear.-A change-speed gear comprises a sleeve carrying the driving-pulley concentrically and rotatably mounted on the crank-shaft and geared to a countershaft within the crank case, the latter shaft being permanently geared with the crank-shaft and sleeve. The countershaft 5, Fig. 3, is driven by the gears 3, 4 at half engine-speed and drives the sleeve 12 through the gears 10, 11. The end of the sleeve 12 is formed as one element of a clutch, the sliding element 15 of which is double-ended and can also engage the clutch member 14 fixed to the crank-shaft 1. The outer surface of the clutch 15 is squared and fits a square hole formed in the boss of the belt pulley 17. A sleeve 22 mounted on the pulley boss is connected to the clutch 15 and engaged by a sliding fork 24 mounted on a pin 25. A small plunger 26 is forced outwards by a spring 27 to engage notches in the pin corresponding to the three positions of the clutch. In modifications giving only a single speed, the pulley 17 is keyed directly to the sleeve 12, which may be detached from the engine. In another modification, the pulley 17 is keyed to the clutch 15 and moves with it. In a further modification, the crank-shaft 1 and sleeve 12 are connected to the drum carrying the driving-pulley, by multiple-disk friction clutches.

Title: Improvements in priming valves for internal combustion engines
IPC: F01L13/08
Filed: 1926-04-17
Abstract: 274,205. Ferruta, F. April 17, 1926. Lift - valves; rotating and grinding valves on seats.-In a screw-down conical priming valve for internal combustion engines wherein the petrol cup 2, Fig. 1, or 6, Fig. 7 is placed on the hand wheel 8, or on the valve casing 5, respectively, the valve 3 is arranged to be closed down upon its seating 12 by an axial non-rotary movement of the valve, the spindle 1 of which is mounted in combination with a clamping member so that it can be set free for rotating the point of the valve against its seating 12 for grinding. In Fig. 1 the spindle 1 is screwed tight into a ring 9 which is provided with guide projections on opposite sides to slide in grooves in the casing to prevent rotation. The valve is closed down and withdrawn by rotation of a screwed sleeve 7. For grinding, the ring 9 is removed from the spindle 1, the sleeve 7 being then replaced in the casing so as to act as a guide whilst rotating the spindle. In Fig. 7 the valve cone 3 is fitted with a removable cotter 9 the ends of which slide in guide grooves in the casing to prevent rotation. The cone moreover has an operating connection with the internally screwed end of the spindle 1 which is screwed into a cap 4 secured to the casing 5. The cone 3 is moved by the differential action of the twosets of screw threads, and for grinding the cotter 7 and cap 4 are removed and the cone scre'wed tight to the spindle 1. Other forms of valve are described and shown in which the externallyscrewed sleeve 7, Fig. 1, is replaced by an internally screwed cap screwing on the exterior part of the valve casing, and in which the valve casing is swivel jointed to a connection screwed to the engine cylinder; a further form is also described in which the screw action in the cap 4, Fig. 7 is dispensed with, the spindle 1 being rotary but non-reciprocating.

Filed: 1958-04-01
Abstract: 826,338. Making pipe fittings; forging; destructible cores. SOC. DE ROBINETTERIE S.A.J. April 1, 1958 [April 5, 1957], No. 10487/58. Classes 83 (2) and 83 (4). A forging press for tubular elements such as T and crossshaped unions, comprises a lower die 2 and a vertically movable upper die 3 adapted to be clamped together to provide an open-ended cavity for the work-piece and carried by a die block 1 slidable horizontally along a bed 6, a stationary punch 7 and a moving punch 8 adapted to press the workpiece from opposite sides of the dies, the movement of the die block being derived from the moving punch through speed reducing means 11-14 such that the speeds of this punch and the die block are in a predetermined ratio. For forging T-shaped unions a tubular workpiece filled with a lowmelting metal or alloy or with rubber or glycol, is inserted in the lower die 2 and the upper die 3 is then lowered by an hydraulic jack 4. Pressure is then applied to punch 8 by an hydraulic jack 9 and the movement thereof is transmitted to the die block 1 through rack 14 meshing with pinion 11 carried by the die block and meshing with fixed rack 13. Thus the workpiece is upset between the punches 7, 8 to produce the crosspiece 10. Spigot ends may be provided on the punches, Fig. 3 (not shown), to enter the bore of the workpiece. In another embodiment, Fig. 5 (not shown), the movement of the punch 8 is transmitted to the die block 1 by a variable ratio lever system. In a further embodiment, Fig. 4, two elements are forged simultaneously by pairs of parallel punches 7, 8. The upper die 3 is operated through a toggle linkage 25, 27 by a pneumatic jack 33.

Title: Method for the production of cheese
IPC: A23C19/05
Filed: 1961-03-23
Abstract: 989,176. Cheese manufacture. JOL. A. BENCKISER G.m.b.H. CHEMISE FABRIK. March 23, 1961 [Sept. 17, 1960], No. 10621/61. Addition to 862,067. Heading A2B. The method for .the manufacture and batch-wise discharge of cheese using helical screw conveyers as described and claimed in the parent Specification is improved or modified by separating the curds used from the whey and/or washing them in a rotating drum 6 substantially horizontally mounted and having orifices 12 in its walls through which liquid passes while curd is retained, inclined delivery plates 15 preferably adjustable in inclination being provided within the drum so that they act to move the curd along and to prevent its agglomeration. A polyamide gauze 13 is placed around the drum to prevent fine particles of curd escaping through the orifices, which are usually about 1.5 mm. in width, and longitudinally arranged bristles 13a are provided within the drum to scrape off the fine particles of curd trapped in the gauze. The curd, when drained of whey and washed, discharges through larger orifices 14 normally covered by a rubber sleeve 17 and/or through a feeder baffle 15a attached to an outlet 16 provided with a cover 16a. The curd collected in vessel 18 is carried by conveyer 20 to the hopper 21 of the vacuum screw press 22 described in the parent Specification. Whey or wash water is drained into a receptacle 19 furnished with a sieve 19b to retain any small particles of curd. In a preferred procedure, curds and whey are passed into the rotary drum, the curds are drained, washed, salted with sodium chloride and/or phosphates, and then removed from the drum and passed along the conveyer to be packed at such a rate that there is always curd awaiting packing at the nozzle 23, a continuous packing process being thereby effected. The four examples of cheesemaking described are similar to Example 1 of the parent Specification.

Abstract: 459,827. Elastic - fiuid turbines. SOC. RATEAU, 40, Rue du ColiseÚ, Paris. April 16, 1936, No. 10962. Convention date, April 29, 1935. [Class 110 (iii)] [See also Group XII] Combustion is con-6 trolled in a firebox supplied with air under pressure by a blower driven by a turbine actuated by combustion products from the firebox by means of a damper arranged in a pipe connecting the delivery of the blower with the intake of the turbine. As shown in Fig. 1, liquid fuel is supplied to the firebox of a boiler by a burner 6 and air for combustion is supplied through a pipe 5 from a blower 1 driven by a gas turbine 2 actuated by combustion products leaving the boiler flue 9. The blower is also driven by a steam turbine or other auxiliary motor 3. A pipe 11 connects the delivery 5 of the blower with the flue 9 and is controlled by a damper 12 actuated by hand or automatically by a device ensuring a constant ratio between the fuel and air supplies. For this purpose diaphragms 14, 17 actuated in accordance with the supplies of fuel and air are connected by levers to the damper 12. If the blower rotates above a predetermined speed a governor 24 actuates a damper 28 in a pipe 29 to permit air from the blower to pass to the atmosphere or to the exhaust flue 10 of the turbine. In passing to the exhaust flue the air from the pipe 29 may be led, as shown in Fig. 2, through pipes 30, 31 and chambers 32, 33 to spaces 35, 36 between the rotor 34 and stator of the turbine for cooling purposes.
