Title: Process of preparing enzyme-peroxidized peanut oil
IPC: A21D2/16
Filed: 1947-03-12
Abstract: Peroxidized peanut oil is made by contacting peanut oil and free oxygen in the presence of an extract of fat peroxidizing enzymes derived from peanuts, e.g. by the agitation in water containing 0.1 per cent of calcium chloride, without aeration, of peanuts extracted by a cold oil solvent or the cake obtained on pressing oil from peanuts without application of heat.  An example is concerned with agitating such an aqueous extract with peanut oil for 30 minutes at a temperature rising from 12 DEG  to 26 DEG  C., the degree of peroxidation then being 0.047 gram molecules of hydrogen peroxide per 1000 g. of oil, heating to 43-45 DEG  C., allowing the aqueous portion to settle and draining it off, and centrifuging the peroxidized oil from remaining water and any protein residue. The peroxidized oil is preferably mixed with hydrogenated peanut oil to form a solid shortening.  Specifications 423,971, 511,701, 513,514, 549,703 and 549,731, [Group I], are referred to.  The Specification as open to inspection under Sect. 91 comprises also the preparation of oxidation products by contacting any oxidizable organic matter, exemplified by any leguminous seed oil, and free oxygen in the presence of an enzymic material derived from the same, or a different, raw material as the organic matter to be oxidized.  This subject-matter does not appear in the Specification as accepted.ALSO:Peroxidized peanut oil suitable for use as a bleaching agent in bread dough is made by contacting peanut oil and free oxygen in the presence of an extract of fat peroxidizing enzymes derived from peanuts, e.g. by the agitation in water containing 0.1 per cent of calcium chloride, without aeration, of peanuts extracted by a cold oil solvent or the cake obtained on pressing oil from peanuts without application of heat.

Title: Improvements in steering mechanism for self propelled vehicles
IPC: B62D3/06
Filed: 1926-03-13
Abstract: 274,153. Royce, F. H. March 13, 1926. Steering. - In vehicles having steering-gear with a large amount of mechanical advantage so as to be irreversible or nearly so, elastic means are provided acting on the steering-shaft so as to tend to return it to its normal position. Three constructions are described. (1) A long coil spring encircles the steering-shaft and is secured at one end to the shaft and at the other end to the steering column. The fixing at the latter end is adjustable to enable the torsion of the spring to be varied. (2) The steering-shaft b, Fig. 3, is formed with an enlarged screwed part e engaged by a nut f slidably-keyed at f<2> to the steering column. Springs .i, i<1> press against collars g fixed to the shaft and against other collars h which are loose on the shaft and abut against the enlarged portion of the shaft. When the shaft is rotated in either direction the nut moves axially and one spring is compressed, the other being unaffected since its collar h is prevented from moving towards the other spring. (3) In the construction shown in Fig. 4 the shaft b is formed with longitudinal serrations engaged by a member k having a screw thread engaged by a nut l anchored to the steering' column. Torsion springs o, o<1> on the shaft are fixed at one end to collars m fixed on the shaft and at the other end to loose collars n abutting against the shoulder on the shaft formed by the serrated part. Each collar n is formed with a cam or inclined end having a single projection, and the members k, l are formed with corresponding surfaces. The nut l normally anchors both springs against rotary movement, but when the shaft is rotated the member k moves axially towards one of the collars n as well as rotates and so rotates this collar against the torque of its spring.

Abstract: 447,307. Printing processes. LOWENSOHN, R., 80, Van Cortlandt Park South, New York, U.S.A. March 6, 1935, No. 7039. Convention date, March 6, 1934. Drawings to Specification. [Class 100 (ii)] A method, of printing comprises applying one ink to a part of a type set-up, applying another ink to the entire surface with the latter ink in superposed relation with the first ink on the part of the surface bearing this first ink, and finally printing from the entire set-up in a single impression, the physical properties of the inks being such as to cause contrasting printing from the different portions of the printing-surface. The invention is used to facilitate proof-reading, more particularly when printing, for example, a yearly alphabetical index or the like which is a compilation of four quarterly indexes ; for the second and subsequent quarterly indexes, the first ink is applied to the type representing changes or insertions, so that these changes or insertions appear in a different colour in the proof, and are thereby distinguished from the matter already proof-read. The ink applied to the type to be inserted is preferably a slower drying ink of greater tackiness than the ink applied to the complete set-up, and is also darker in colour. The Specification as open to inspection under Sect. 91 states that any writing, marking, engraving, or impressing materials, whether solid or liquid, and whether dependent on chemical or mechanical action or both, may be used. This subject-matter does not appear in the Specification as accepted.

[Also in Division C5] The invention comprises compounds of formula R 1 R 2 CClLi, where R 1  is an aryl group and R 2  is the same or a different aryl group, hydrogen or halogen, or R 1  and R 2  are both hydrogen. Specified compounds are PhCCl 2 Li, Ph 2 CClLi. They may be prepared by reacting compounds R 1 R 2 CClX (where R 1 , R 2  are as above and X is hydrogen or halogen) with C 1 -C 5  alkyllithium compounds in tetrahydrofuran (and mixtures thereof with diethyl ether or 1,2-dimethoxyethane), 1,2-dimethoxyethane or diethylene glycol dimethyl ether below - 65‹ C. at which temperatures the compounds are stable. PhCCl 2 Li may be prepared from PhCCl 3  or PhCHCl 2 , and Ph 2 CClLi from Ph 2 CCl 2  using n-butyllithium. Carboxylation of PhCCl 2 Li with dry ice yields PhCCl 2 .CO 2 Li which dissolves in water producing PhCO.CO 2 H, and of Ph 2 CClLi yields Ph 2 C(OH)CO 2 H. PhCCl 2 Li may be hydrolysed to PhCCl 2 H or methanolysed with CH 3 OD to PhCCl 2 D. Reaction of PhCCl 2 Li with methyl iodide yields PhCCl 2 .CH 3  which may be hydrolysed to Ph.CO.CH 3 ; a similar reaction may take place with benzyl chloride. The compounds decompose above - 65‹ C. and, if an olefin is present in solution, react therewith to produce a cyclopropane, e.g. PhCCl 2 Li reacts with tetramethylethylene yielding
