Title: Improvements in or relating to treating or refining glyceride oils and fats
IPC: C11B3/06
Filed: 1939-09-27
Abstract: 537,704. Refining oils and fats. CLAYTON, W. I., FLEMING, L., WHITTINGTON, H., FUESLER, J. P., CANNAFAX D., SUMNERS, D., McASHAN, S. M., ODEN, S., and ANDERSON, W. L., [trading as ANDERSON, CLAYTON & CO.]. Sept. 27, 1939, No. 26736. Convention date, Oct. 13, 1938. [Class 91] Glyceride oils or fats which contain colloidal impurities such as colouring matters are refined by admixing the oil or fat with a highly dispersed electrically charged colloidal suspension opposite in charge to the charge on the impurity to be removed in an amount such that the electrical charge on the added colloid is at least approximately equivalent to the charge on the impurity to be removed. The added colloid is preferably in aqueous suspension. Since it has been found that a major portion of the colouring matter in vegetable oils is positively charged, the added colloid is therefore usually negatively charged, the preferred reagent being a colloidal suspension of chromic oxide. 'If the vegetable oil contains a considerable amount of free fatty acid, this is neutralized by treatment with the appropriate amount of caustic soda. The admixture of the added colloid with the oil is carried out by the use of a high speed agitator. The Specification as open to inspection under Sect. 91, includes in addition to the treatment of glyceride oils or fats, also the treatment of any non-aqueous liquid. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to hydraulic servo mechanisms for adjustable ratio dualfuel systems
Inventor: STARKEY NEAL EYFERTH
IPC: F02C9/40
Filed: 1952-10-27
Abstract: 731,622. Gas turbine plant. GENERAL ELECTRIC CO. Oct. 27, 1952, No. 26929/52. Class 110 (3). [Also in Group XXIX] A hydraulic servo mechanism for a dual fuel supply system for a thermal power plant, e.g. a gas turbine, comprises a main pilot valve 30 positioned by a force from an expansible chamber 27 proportional to a first pressure P<SP>1</SP> and an opposite force from a second expansible chamber 24 proportional to a second pressure P<SP>2</SP>, the valve 30 controlling the flow of operating liquid to the chamber 24 to establish the pressure P<SP>2</SP>, an auxiliary pilot valve 37 positioned by a force from a third expansible chamber 25 proportional to a third pressure P<SP>3</SP> the valve 37 controlling the flow of operating liquid to the chamber 25 to establish the pressure P<SP>3</SP> which pressure is communicated to the chamber 26 in opposition to the first pressure P<SP>1</SP>, and a lever 40 connecting the auxiliary valve with the second expansible chamber whereby the main pilot valve is positioned with P<SP>1</SP> proportional to P<SP>2</SP>+P<SP>3</SP> and the ratio of P2 to P<SP>3</SP> is a preselected constant. The fluid pressure P<SP>1</SP>, which is a function of the rate of fuel supply required, is derived from a regulator, e.g. of the general type disclosed in Specifications 638,494 and 700,092, [Group XXXV] in response to operating characteristics of the power plant such as speed, motive fluid temperature, atmospheric temperature and pressure, and the position of an automatic or manual control member, acts via a pipe 46, annular passage 47 and pipe 48 in the bellows 27 to shift the valve 30 downwards. This allows fluid to pass the land 30 to establish the pressure P 2  which acts via passage 50 in the bellows 24 and also via pipe 51 to a bellows for actuating a valve controlling a first fuel supply, e.g. fuel oil. The pressure fluid also passes via pipe 46a, auxiliary pilot valve land 37 and pipe, 54 to establish the pressure P<SP>3</SP> in the bellows 25 and in the space 26. This pressure P<SP>3</SP> is led via pipe 55 to a bellows operating a valve controlling the supply of a second fuel, e.g. fuel gas. Thus the combined supply of the two fuels varies according to P<SP>2</SP>+P<SP>3</SP>, i.e. to the regulator pressure P<SP>1</SP>, while the ratio of the two fuel supplies and of the pressures P<SP>2</SP>, P<SP>3</SP>, acting on the pilot valve 30 and through the lever 40 on pilot valve 37 is determined by the position of the fulcrum 41 of the lever adjustable by the screw 44. Specification 15817/48, as open to inspection under Sect. 91, also is referred to.

In one embodiment described, Fig. 5, a card 10 is inserted through opening 21 operating a photo-electric switch (not shown) to energize electric motor 24, which drives rollers 36, 40, 46 and 50. The card is conveyed, past magnetic reading head 44, until it is brought to rest by stopper 52. A record slip 56 which may be of pressure sensitive paper is inserted into shoot 54 and is also brought to rest by stopper 52, the slip being of sufficient length to permit easy withdrawal. Two photo-electric switches sense the positions of the card and slip and energize two solenoids 60 and (62) (Fig. 4, not shown). Solenoid 60 has a plunger 64, which through linkage 68, 70 urges platen roller 74 towards roller 50. Solenoid (62) similarly moves a pressure roller (84) to nip the card and slip between rollers 50 and (84). The movement of link 70 also pivots lever 88 to remove the stopper 52 from the path of the card and slip allowing them to be moved forward so that the embossed data is imprinted on the slip. A suitable switch detects when the imprinting operation is complete, de-energizing solenoid 60 and reversing the direction of motor 24 to return the card to its owner through slot 21 and deliver the slip to shoot 56. In another embodiment (Figs. 6 to 8, not shown) the card and slip are held stationary on a support member 329 and a platen roller (136) is moved over them to perfom the imprinting operation. In a further embodiment (Figs. 9 to 11, not shown) a similar movable platen roller (136) is used but the record slip is inserted through a lateral slot (202). In another embodiment (Fig. 12, not shown) a continuous record sheet (306) comprising a plurality of slips is used, being fed from roller (333) to take-up roller (332). In this embodiment the date of the transaction is also printed on the slip by means of inked ribbon (319), date type (318) and push rod (317).
