Title: Improvements in vacuum steam heating system
IPC: F24D19/08
Filed: 1929-07-04
Abstract: 329,884. Jennings, I. C. July 4, 1929. Heating by circulation of fluids.-In a vacuum steam heating system, the wet vacuum pumping apparatus is driven by a turbine supplied by lowpressure steam from the same boiler, and the exhaust steam passes into the heating system. A boiler A, Fig. 1, supplies low pressure-steam through pipes A', B to radiators C, the exhaust from which passes into a return line F and thence to a separating tank H. The pumping apparatus I comprises a hydro-turbine air pump J, Fig. 2, and a centrifugal water pump! K. The pump J is connected by pipe J', Fig. 7, to exhaust air and gas from the top of the tank H and deliver through separator L to escape M. Water returns through float valve L<1> to the tank H. The pump K draws water from the bottom of the tank H and returns it through pipe N to the boiler. A bye-pass 0 is provided between the return line F and the boiler. The air pump J is supplied with the water necessary for its operation by a connection opening into the tank H at a level lower than the connection J<4> to the pump K. Such a system is usually supplied with steam of 4-5 lb. pressure with a partial vacuum of 5 1b. in the return line, such pressure difference being normally too low to drive a steam turbine satisfactorily, but the. turbine may be satisfactorily operated if it is provided with a large number of inlet jets or nozzles. The exhaust from the turbine passes through pipe V to the radiator supply pipe B. The necessary pressure difference between the pipes Q, V is maintained by a pressure regulating valve W, at, say, 3 lb. The valve W is operated automatically by the pressures on its two sides acting on opposite sides of a diaphragm, and the setting is adjustable by means of a weight w<2>. The speed of the turbine is thus maintained constant notwithstanding variations in boiler pressure, the surplus steam passing direct to the heating system. The pumping apparatus may be automatically controlled by a valve X operated hy a diaphragm subjected to the vacuum in the pipe F, or by a valve Z operated by a float in the separating tank H, so that the turbine, is operated by a constant pressure difference if either valve X or Z is opened. The turbine casing is connected by a thermostatic or float trap v<1> to the return line F to allow escape of water.

Title: Improvements in or relating to methods of producing pastry
IPC: A21D2/26
Filed: 1956-07-03
Abstract: A dry pastry comprising flour, a fatty substance, not more than 8% by weight moisture, and 10 to 45% by dry weight of edible protein is made in a process comprising forming a dough containing water, flour, and a fatty substance, and including therein the dry protein in the form of individual particles each surrounded by a layer which is substantially impermeable to water, the layers consisting of all or part of the fatty substance in the dough. The fatty substance, which preferably forms 10 to 20% by weight of dry substance in the dough and has a melting-point between 20 DEG  and 45 DEG  C., can consist of solid higher hydrocarbons, fats, waxes, and/or solid fatty acids. Edible animal or vegetable fat is preferred, e.g. palm-kernel fat, coconut fat, arachis oil, colza oil, cottonseed oil, lard or hardened train oil.  The flour content can vary between 30 and 50% by weight of dough and be derived from wheat, rye, maize, rice and mixtures thereof. Proteins are exemplified by casein, gluten, proteins from peas, beans, lentils, such as soya beans, arachis, proteins from tubers (potatoes), animal proteins, e.g. meat- and/or fish - proteins, and lactalbumin.  Vitamins A, B, C or D, sugars, e.g. saccharose and glucose, flavouring materials, e.g. salt, and raising means, e.g. yeast, sodium bicarbonate, may be added to the dough.  In an example biscuits and crackers are made by baking doughs.

Title: An improved outboard drive for boats
IPC: B63H20/18
Filed: 1938-07-12
Abstract: 516,974. Outboard drives. ARMSTRONG, A. July 12, 1938, Nos. 20699 and 33453. [Class 114] An outboard drive for boats is mounted on the stern and can be swung radially in both a transverse and a longitudinal plane. The swivel plate 5 registers concentrically with the transom base plate 2 by means of a sleeve extension 50 which registers with the centre bore of the base plate sleeve 2a, and is secured rotatably thereon by means of shoe pieces 4. The propeller drive casing 6 is pivotally mounted about a pin 7 between the brackets 56 on the swivel plate 5. The vertical cylindrical casing 8 and the lower end of casing 6 contain a vertical steering sleeve 9 integral with the propeller casing 31. Steering is effected by rotating the sleeve 9 by means of worm gear 10 actuated by the steering shaft 15 through pinions 13 and 14. These latter are located on a radius when the drive casing is vertical, so that when the drive casing is swung radially, the pinion 13 will swing out of mesh with the pinion 14, thereby interrupting the steering transmission. If. the casing swings longitudinally through meeting an obstruction, the said pinion will disengage axially. Power transmission is effected by a longitudinal shaft 26 connected at its inner end to the motor, and at its outer end to the horizonal shaft 23 in the drive casing 6 by means of dog members 24 and 25. Power is transmitted from shaft 23 to the vertical shaft 17 through bevel gears 22 and 21, and thence to the propeller shaft 20 through bevel gears 18 and 19. When the drive is tilted rearwards the dogs 24 and 25 disengage. The drive casing is held in position normally by a shear pin 30 which fractures under a severe blow thus allowing the casing to swing rearwards. The shear pin is relieved of propeller thrust during astern motion by the provision of an annular segment 31a on the propeller casing 31 which engages behind a similar segment 29b at the base of the swivel plate 5 when the casing is rotated into reverse position. The drive casing is arranged, on tilting rearwards, to trip an engine ignition switch, and to reset it on returning to normal position. When swung transversely, the drive can be locked in set positions by means of a spring-pressed detent 32 at the top of the transom base plate 2, which engages with any one of the bores of four bosses 5d in the swivel plate 5. Transverse swinging can be effected by hand. or by a hand wheel 36 geared to the sleeve 5c. An extended anti-cavitation plate may be arranged adjustably on the propeller casing to be used as an additional planing surface.
