Patent GB-436877-A (GB)
Title: Improvements in or relating to the saccharification of cellulosic materials
Filed: 1934-04-20
Abstract: In the saccharification of cellulosic material by means of sulphuric acid, the acid is recovered in the form of ferric sulphate or other sulphate which evolves sulphur trioxide when heated by adding ferric oxide or other suitable oxide to the liquor.  Cupric oxide may, for example, be used instead of ferric oxide, and mixtures of ferric and cupric oxides can be employed. The method is especially applicable in processes in which the cellulosic material is first dissolved in strong sulphuric acid and the solution obtained diluted, for example, to a concentration of more than two per cent, and heated to saccharify the intermediate product formed; but it may also be applied in single stage processes in which the material is dissolved in dilute acid, for example, of less than two per cent concentration. The residue formed by heating the ferric sulphate to form sulphur trioxide may be hydrated with steam to facilitate solution in further acid liquor.  The sulphur trioxide is absorbed, for example, in diluted sulphuric acid, to form concentrated acid for the treatment of fresh cellulosic material.  The heating of the ferric sulphate need not be continued until all the sulphur trioxide is driven off, for example, the sulphate may be fed down an externally heated flue and withdrawn from a hearth at the base at such a rate that the desired proportion of sulphur trioxide is given off.  An example is included.

Title: Improvements relating to regulating means for alternating electric current generators
IPC: H02P9/34
Filed: 1945-05-14
Abstract: 596,244. Automatic control systems for alternators. LUCAS, Ltd., J., LAIRD, J. A., and JONES, J. W. REID-. May 14, 1945, No. 12015. [Class 38 (iv)] In a voltage regulating device for selfexcited alternators the machine field is energized from the alternator output through a full-wave rectifier and a winding, the impedance of which is controlled by the alternator output voltage through a thyratron as shown, the field c2 of alternator c is supplied from the generating winding c<1> through transformer a and full-wave rectifier d. The impedance e<1> in series with d is subject to the control of winding e<2> the current through which is passed by thyratron o, rendered sensitive to changes in alternator output voltage by the thermionic valve circuit i associated with the secondary b<2> of transformer b. A rise in the alternator output voltage produced in winding c<1> causes a corresponding increase in the D.C. voltage applied to the triode valve m from the rectifier g and condenser f and thereby raised the valve current which flows through the resistor k and lowers the potential of the anode of valve m and the grid o<2> of thyratron o. The current in regulating winding e<2> falls, the impedance of winding e<1> rises and the excitation of field winding c2 is reduced. Conversely, a fall of alternator output voltage effects a rise in the machine exciting current. To prevent hunting a resistor q in series with a condenser p may be connected in the grid-cathode circuit of valve m.

Title: Improvements in or relating to the manufacture of fatty esters
Inventor: KOEBNER ADOLF
IPC: C11C3/04
Filed: 1956-04-19
Abstract: Glycerol is obtained when glyceride oils, such as coconut, castor, and sperm oil, are reacted with primary alcohols such as methanol and butanol in the presence of barium oxide.  The reaction mixture forms two layers, the lower of which is glycerol. The glycerol so obtained may contain barium soap, barium hydroxide, and barium carbonate impurities; these may be removed either by passing carbon dioxide into the glycerol or by adding a quantitative amount of sulphuric acid, and filtering off the insoluble barium carbonate or sulphate formed.  The product may then be further purified by ion-exchange processes. Specifications 587,530, 587,532 and 587,533 are referred to.ALSO:Fatty acid esters of primary alcohols are produced from glyceride oils by reacting in the presence of barium oxide a glyceride oil with a primary alcohol to form a primary alcohol fatty acid ester, glycerol and barium soaps, and separating the glycerol and barium soaps from the ester, the whole or a major part of the barium soaps being removed from the ester by filtration.  Any excess primary alcohol present in the mixture may be removed before the filtration.  Preferably the glyceride oil and primary alcohol are reacted in the presence of barium oxide at a temperature of 70 DEG to 85 DEG  C.  The glycerol which forms the lower layer is drawn off. The upper layer is allowed to cool and the barium soap is filtered off.  In the examples: (a) coconut oil, anhydrous methanol and barium oxide are stirred at 75 DEG  C., the glycerol formed is drawn off, the mixture is cooled and the barium soap is filtered off; if desired excess methanol may be removed by stripping prior to the filtration stage; (b) castor oil is treated at 80 DEG  C. with n-butanol in the presence of barium oxide; the glycerol is separated, the butanol is stripped off and the castor oil butyl esters are filtered from the barium soaps; and (c) sperm oil is treated with methanol in the presence of barium oxide to give a mixture of higher fatty acid methyl esters and cetyl, stearyl and oleyl alcohol.  Specifications 587,530, 587,532 and 587,533, [all in Group IV], are referred to.

Filed: 1925-05-13
Abstract: 236,526. Bendix Brake Co., (Assignees of Dodge, A. Y.). July 2, 1924, [Convention date]. Blocks and shoes acting on drums.-Relates to brakes of the internal expanding type comprising a pair of shoes connected by a floating pivot so that the application of one of the pair is assisted by the frictional reaction on the other. Fig. 1 shows a form comprising a pair of shoes 2, 3 connected by a floating pivot 4, and mounted on a fixed pivot 7 and a third shoe 5 mounted on a fixed pivot 6. The shoes 2, 5 are engaged by a cam 9 the pivot axis 15 of which is eccentric so that there is a tendency to balance the forces on opposite faces of the cam, the arrangement of the shoes being such that one part of the cam must be moved further than the other part in order that the forces thereon may balance. The shoes 3, 5 are arranged to overlap as described in Specification 245,459 so that the gap between the friction surfaces thereof is reduced to a minimum. With the drum rotating in the direction of the arrow, the frictional reaction on the shoe 2 increases the pressure on the shoe 3 applied by the cam 9. With reversed rotation this intensifying action of the shoes 2, 3 is not produced but the shoe 5 being pivoted at a point towards the centre of the drum, the frictional force augments the pressure applied by the cam to this shoe. Releasing springs 10, 11 extend between the shoes 2, 5 and between the shoe 3 and a fixed point 12 respectively. The position of the joint 4 is adjustable by an eccentric 14 as described in Specification 244,037. According to the Specification as open to inspection under Sect. 91 (3) (a) the shoe 5 may comprise two articulated sections. This subject matter does not appear in the Specification as accepted.
