Abstract: 554,010. Food preparations. DISTILLERS CO., Ltd., and MEYER, E. A. Sept. 17, 1941, No. 11931. [Class 49] Yeast is subjected to a plasmolysing agent such as sodium chloride, and then allowed to autolyse. Without filtration, the percentage water content is reduced, either by evaporation or by the addition of a dry food product, such as dried yeast or by both methods. The water content may be reduced either before or after autolysation. Removal may be effected by drum drying or by spray drying. Before the foregoing treatment the yeast may have been subjected to debittering. Meat and vegetable extracts and flavouring ingredients may be incorporated, e.g. dried celery.

Title: Improvements in and relating to hydraulic turbines
Inventor: SEEWER PAUL WERNER
IPC: F03B15/18
Filed: 1952-05-12
Abstract: 722,048. Hydraulic turbines. ENGLISH ELECTRIC CO., Ltd. May 8, 1953 [May 12, 1952; Dec. 5, 1952], Nos. 11949/52 and 30923/52. Class 110 (3). In a hydraulic turbine of the fixed propeller type or of the feathering runner blade type, hydro-brake vanes are normally held by means of springs in a retracted position within a housing rigidly connected to the turbine runner, the action of the springs being overcome by centrifugal force of the hydro-brake vanes when the turbine reaches a predetermined overspeed. The springs automatically retract the vanes when the speed of the turbine has been reduced to a speed considerably below the overspeed. The hydro-brake vanes are interlinked with one another whereby they are all projected and retracted simultaneously. In the right-hand side of Figs. 1 and 2 (11949/52), the hub 1 of the rotor carries pivoted blades 2 and a hydro-brake ring 7 fixed to the top of the hub. Hydro-brake vanes 8 are pivoted at 9 to the ring 7 and each is normally held by a pair of springs 10 in the retracted position shown by full lines. In the event of overspeed, the vanes 8 move outwardly to the position shown by chain-dotted lines against the action of the springs and are returned by the action of the springs to the retracted position when the speed falls. In the left-hand side of these Figs., the pivoted hydro-brake vanes are interconnected by springs 14 disposed in a plane normal to the rotor axis, the springs being extended when the vanes move outwardly in the event of overspeed. In Fig. 1 (30923/52) the vanes 8 are pivoted to the hydro-brake ring 71 and compression springs 10<SP>11</SP> are mounted between abutments formed in the ring 71 and 18 pivotally mounted at the end of a lever 161 fixed to the axle 9 of the vane 8. In a further embodiment, the inner end of each hydro-brake vane is formed with a cam surface which bears against a leaf spring secured to the hydrobrake ring; and in another embodiment, a ferrule by which a compression spring is connected to the hydro-brake vane is eccentrically mounted on a pivot so that the length of the effective lever arm of the spring and the spring force may be adjusted. In Fig. 4 (30923/52) a cable 31 is connected to the hydro-brake vane 8 and passes over a pulley 32 mounted on a rotating part connected to the turbine rotor. An indicator rod 36 is connected to the cable, the rod being guided in a bush 37 and loaded by a light spring 39. The end 36<SP>1</SP> of the rod 36 projects through a cover plate 38 and its position indicates the position of the hydro-brake vane. Specification 555,333 is referred to.

IPC: C01G28/02
Filed: 1926-05-07
Abstract: 273,440. Harris, H. May 7, 1926. Sodium stannate; sodium arsenate.-Mixtures of sodium stannate and sodium arsenate, with or without sodium antimonate, are treated, in the cold with caustic soda solution of such strength as to dissolve only the sodium stannate, the resulting solution being separated from the residue, and the latter being treated for the recovery of pure sodium arsenate. When treating mixtures consisting only of sodium stannate and arsenate, the solution used may contain from 100 to 250 grms. of caustic soda per litre, but when the mixtures contains free caustic soda, and salts such as sodium chloride or sodium carbonate, as is the case, for instance, with mixtures obtained by the processes described in Specifications 213,638 and 245,479, the strength of the caustic soda solution may be reduced. For example, a mixture containing 5.1 per cent sodium chloride, 5.8 per cent sodium carbonate, and 3:5 per cent caustic soda, may be treated with a solution containing 58 grms. of caustic soda fer litre.

Title: Improvements in or relating to implements for laterally displacing crops lying on the ground
IPC: A01D78/00
Filed: 1956-04-19
Abstract: 827,737. Hay-making. VAN DER LELY, N. V., C. April 19, 1956 [April 28, 1955], No. 12022/56. Class 6(3). An implement for laterally displacing crop lying on the ground comprises a frame supporting at least two rake wheels whose axes of rotation are parallel, the frame being connected to the power lift linkage of a tractor by a coupling device which allows the frame to be displaced relative to said coupling device about an axis which is horizontal and perpendicular to the axes of rotation of the rake wheels. A frame comprising members 10, 13 and 14 (see Fig. 3) is attached to the lift arms 3 and 5 of the power lift linkage of a tractor by means of bolts 11 and 12 and supports a further frame 18 which can pivot about bolts 19 and 20. The frame 18 comprises a bracket which is rotatable about the pin 23, the said bracket having fixed thereto a sleeve 25 which rotatably houses the forwardly extending shaft 26 of the frame carrying the rake wheels. Thus the shaft 26 and the beam 29 which carries the rake wheels can pivot about the pin 23 in order to counteract any irregularities of the ground, this latter movement being controlled by the spring 65 and being prevented when desired by inserting a pin 68 mounted in a side member of the frame 18 into any one of a series of holes in an arcuate strip 69 fixed on the sleeve 25. Since the frame 18 can pivot about the bolts 19 and 20, the direction of the shaft 26 relative to the direction of travel of the implement may be varied, and the shaft may be locked at the desired angle to this direction by means of a pin to passing through an arm fixed to the frame 18 and selectively engaging holes in an arcuate strip 62 fixed to the bracket 10. The forward end of the shaft 26 is hollow and is formed with two slots 52 and 53, and with a hole 54 (see Fig. 5), either of which may be engaged by a spring-urged pin 57 passing through a hole in the sleeve 25. By withdrawing the pin 57 from the slot 52, rotating the beam through 180 degrees and reinserting the pin in the slot 53, the implement may be converted from a side delivery rake to a tedder, and in either of these two positions the beam 29 carrying the rake wheels can pivot to a limited extent about the axis of the shaft 26 by virtue of the fact that the pin 57 will have limited play in either of the slots 52 or 53. By engaging the pin 57 in the hole 54, the beam 29 will be inclined to the horizontal and its overall width can thereby be reduced for transport purposes. In the embodiment shown in Fig. 6, the sleeve 26 is rigidly secured to the frame 18, and in order to allow the beam 29 to move up or down on meeting uneven ground, the shaft 26 is divided into two parts pivotally jointed together by means of brackets mounted on a pin 23A, springs 73 and 74 acting so as to urge the two parts of the shaft into alignment. Reference has been directed by the Comptroller to Specification 793,434.

Title: Liquid metering and dispensing bottle closure device
IPC: B65D47/20
Filed: 1974-03-20
Abstract: 1434892 Combined measuring and dispensing device; dispensing/venting SOC ANGELO GUALA DI PIERGIACOMO E ROBERTO GUALA & C SAS 20 March 1974 [27 March 1973] 12373/74 Addition to 1302677 Headings B8T and B8V A liquid measuring and dispensing device comprises an outer body 102 of circular crosssection which is secured to the neck 1 of a bottle and which has mounted concentrically within it a cylindrical member 110 closed at one end by a circular wall 111. The volume enclosed within the cylindrical member and the end wall forms a metering chamber A whilst the space between the cylindrical member and the outer body forms an annular pouring orifice B. The metering chamber communicates with the interior of the bottle via an air inlet passage formed by a tube 117 which is connected in turn to a tube 129 extending into the bottle. Longitudinally extending ribs 130 hinder the formation of liquid films which may restrict the flow of air from the metering chamber into the bottle during dispensing of liquid. The metering chamber is also connected to the interior of the bottle via an annular passage formed between tube 117 and an outer tube 119. A moulded element 121 engages a seal 131 on the rim 1a of the bottle and comprises an annular diaphragm 125 bearing apertures 127. In order to dispense its contents, the bottle is tilted so that liquid passes under the action of gravity through the diaphragm 125 and thence through the annular pouring orifice B; air which enters the bottle from the metering chamber A, passes initially into the chamber via an annular aperture formed by a member 113 which abuts the open end of cylindrical member 110, liquid being prevented from entering this orifice by a disc 120 intergral with tube 119. During the dispensing process, liquid gradually enters the metering chamber via the annular passage formed between tubes 117, 119 until the air inlet passage becomes obstructed, at which time dispensing of fluid ceases. In this manner, equal amounts of liquid are dispensed each time the bottle is inverted. In an alternative embodiment, member 113 is omitted and the tube 119 reduced in length. If the bottle is inverted, a fixed quantity of liquid is dispensed as described above. However, if the bottle is held at a small angle to the horizontal, owing to the reduction in length of tube 119 much of the liquid passing through the annular delivery passage formed between tubes 117, 119 does not enter metering chamber A, which consequently fills at a much slower rate than previously; the flow of liquid through the pouring orifice is therefore unhindered by the obstruction of the air inlet passage, thereby permitting the dispensing of an arbitrary amount of liquid.
