Title: Control arrangement for electric vehicles with pneumatic and manual operation of the controller
IPC: B60L15/14
Filed: 1955-12-16
Abstract: 804,551. Controllers. ZAVODY V.I. LENINA NARODNI PODNIK, NOVOTNY, B., and OPIAL, M. Dec. 16, 1955, No. 36219/55. Class 38 (3). A main controller 9 for an electrically-driven vehicle is actuated either manually or by means of a pneumatic motor 1 having control valves 2, 3, which are regulated by an auxiliary controller 4 on the shaft of the motor 1. The main controller is coupled through differential gearing with a control shaft 14 which may be fitted with a hand wheel 15. A further auxiliary controller 18 is rotatably mounted on the shaft 14 and is linked with planet wheels 12, 12<SP>1</SP> forming part of the differential gearing. The controller 4 has contacts 19-22 and the controller 18 is provided with contacts 23-28 in the control circuit of the valves 2, 3. A pointer 32 on the shaft 14 indicates the switching position of the controller on the scale 33. In the zero position of the controller 9, the hand wheel 15 may be transferred from shaft 14 to shaft 34 for operating the controller by hand. When the pneumatic motor is at rest and the hand-wheel is in its zero position, the switches 21, 22 and 23, 24 are closed and the remaining switches are opened, so that coils 2, 3 are de-energized and the controller 9 is held in its zero position. If the hand wheel is turned into its third position, for example, the switch drum 18 is rotated to open switches 23, 24, and close switches 25, 27. The coil 2 is thus energized whereby switch drum 4 is turned to close switch 19 and to energize coil 3. This causes the drum 4 to move another step to open switch 21 so that the pneumatic motor is moved into its final position. During these operations the switch drum 18 is turned back into its zero position wherein the coil 2 is de-energized and the coil 3 is energized to hold the controller in its set position. Thus, the switch drum 4 controls the operation of coils 2, 3 for forward or reverse stepping action of the pneumatic motor, whilst the number of steps is determined by the angular setting of the drum 18;

IPC: C12C7/20
Filed: 1967-08-08
Abstract: 1,187,789. Isohumulates. BUSH BOAKE ALLEN Ltd. 15 Nov., 1967 [15 Nov., 1966; 8 Aug., 1967], Nos. 52064/67 and 36469/67. Heading C2C. [Also in Division C6] A potassium isohumulate-containing hop extract is prepared by (i) extracting hops with an organic solvent (e.g. hexane or benzene); (ii) contacting a solution of the extract in a water-immiscible organic solvent (petroleum ether, hexane or benzene) which dissolves humulates less readily than water with sufficient dilute aqueous sodium or potassium alkali to transfer at least the majority of the humulates into the aqueous phase as a dilute solution of alkali metal humulates but insufficient to transfer the majority of the lupulones into the aqueous phase; (iii) transferring the humulates into a more concentrated solution; and (iv) boiling the concentrated solution to isomerize the humulates, the humulate being converted into the potassium salt either before or after isomerization. When potassium alkali is employed, the aqueous extract obtained is washed with petroleum or benzene. For the transference of the humulates into a more concentrated solution (a) the humulates are precipitated from the aqueous phase as insoluble humulates of a polyvalent metal cation (calcium, magnesium, zinc, copper, strontium or nickel), redissolved in a solvent for the polyvalent metal humulates (methanol), and converted into the potassium humulates or isohumulates by addition of potassium carbonate or passage through the requisite cation exchange material; or (b) the dilute solution of alkali metal humulates is contacted with a polar water-immiscible solvent (specified esters, ketones and alcohols) which dissolves alkali metal humulates more readily than water and a solution of the humulates in the polar water-immiscible solvent is separated from the aqueous phase. The alkali metal humulates are then recovered by salting out. Off flavours in the solution of isomerized humulates are reduced by washing with a water-immiscible non-polar solvent which dissolves isohumulates less readily than water (benzene or petroleum ether). According to an example, hop extract obtained by extracting dried hops with benzene, was dissolved in petroleum ether and the resultant solution was agitated with 2% aqueous sodium carbonate. The aqueous phase (pH 9À1) was treated with calcium chloride and the precipitate of calcium humulates formed was dissolved in absolute methanol and then treated with potassium carbonate. After filtration of the precipitated calcium carbonate, the pH of the filtrate was reduced to 9À0 by citric acid the methanol was distilled off and the residue at pH 10À1 was boiled at atmospheric pressure for 50 minutes to achieve isomerization of the potassium humulates.

A centrifugal fan comprises hollow airfoil impeller blades supported between plates and having openings or slots in their outer sides adjacent their trailing edges, and means for supplying air under pressure into the blades to be blown through the openings. When it is desired to increase the discharge pressure of the fan, a valve 20, Fig. 4, is opened to the required degree to admit compressed air from a source 22 through a seal 19 to the bore 17 of the hollow shaft 18, and thence through radially-extending bores 16 and axially-extending bores 15 in the centre plate 11 to the hollow interiors of blades 14. The compressed air is expelled through slots 26 in the outer sides of the blades adjacent the trailing edges, and deflects the gas passing the outer sides outwardly, producing an effect as if the trailing edges were thickened and their angles of attack increased. The slots 26 may be replaced by pivoted flaps 27, Fig. 5, which are normally kept closed by the centrifugal effect of counterweights 29, but are opened to the dotted position by the compressed air.
