Title: Proteinaceous food product
Inventor: BOYER ROBERT ALLAN
IPC: A23C20/02
Filed: 1971-05-18
Abstract: 1300711 Proteinaceous food products RALSTON PURINA CO 18 May 1971 [25 May 1970 18 Nov 1970 28 April 1971] 15504/71 Heading A2B [Also in Division C3] A cohesive, smooth-textured proteinaceous food product is produced by acidifying a protein-containing aqueous extract of a vegetable protein material (defatted soybean meal or flakes) to precipitate protein therefrom, separating the precipitated protein from the extract in the form of a curd, homogenizing the protein curd to give a uniform slurry, and compacting and heat-setting the slurry. It is preferred to heat the aqueous extract at a temperature in the range 160-310F for 30 minutes to 5 seconds, prior to the acidification, whereby a "fluffy" curd will be obtained. The slurry may be compacted by subjecting it to a vacuum of at least 27 inches of mercury to remove entrapped gases. Alternatively, the slurry may be simultaneously compacted (under pressure) and heat set by passage under agitation through a series of heat exchangers. Examples are directed to the preparation of butter-or cheese-type spreads, sliceable food products resembling a processed cheese and a chocolate flavoured pudding, comprised of the proteinaceous food prpduct and such other ingredients as salt, sugar, corn syrup, starch, gum, vegetable oil, milk solids, sodium casemate, powdered cheese flavouring or cocoa, colouring and sorbic acid, which are added prior to the homogenizing step.

Title: Improvement in airplane control system
IPC: B64C13/00
Filed: 1946-05-23
Abstract: 612,279. Aircraft control. ENGINEERING & RESEARCH CORPORATION. May 23, 1946, No. 15594. Convention date, June 15, 1945. [Class 4] In aircraft, having hinged ailerons 2, 4 on the wings, normal control means 20 for differentially moving the ailerons about their hinge axes C-C to provide lateral control and also means for moving the ailerons about their hinge , axes to similar drooping positions to produce a high lift effect, there is provided a vertical rudder 14, which upon differential operation of the ailerons from either their normal undeflected positions or from similar drooping positions, is moved to oppose adverse yawing moments due to differential operation of the ailerons. Provision may be made for the movement of the rudder to be greater in the case where the ailerons are differentially moved from similar drooping positions. The rudder is moved by a rod 32 connected to one end of a pivoted lever 30 with its other end connected to a rod 28 offset from control lever 20, which is rotated about a vertical axis for differential operation of the ailerons; a bell-crank lever 34 integral with lever 30 differentially operates the ailerons through rods 36 connected through J-levers 38, Fig. 2, to rods 42 for turning the ailerons. A separate lever 50 is turned rearwardly to set both ailerons in drooping positions for highlift, a lever 62 being turned by rod 52, connected to lever 50, and actuating the ailerons through rods 64 connected to triangular connecting members 40 which are pivoted to J- levers 38. A central high-lift flap 6 is operated by a rod 60 connected to a crank 58 moved at the same time as lever 62. The increased rudder movement for the case where the ailerons are differentially moved from similar drooped positions is obtained by connecting rudder rod 32 by an adjustable pivoted lever (not shown) to rod 30, the adjustment being effected when the control rod is moved rearwardly for obtaining high-lift controls from the ailerons. U.S.A. Specification 2,110,516 is referred to.

Title: Improvements in printing mechanism for calculating machines
IPC: G06C11/04
Filed: 1920-06-09
Abstract: 144,685. Federal Adding Machine Corporation, (Assignees of Wales, C.). May 5, 1919, [Convention date]. Type - bar machines ; hammer - impression arrangements.-Relates to printing-mechanism for key-set independently-actuated calculating- machines having a differentially-set type-carrier for each denomination, and consists in the provision of means for controlling and actuating the impression-hammers wherein (1) the type bars positively act to move the hammer locks to hammer-releasing position, (2) a member is actuated to permit the hammer locks to be moved from locking position and causes the hammer locks which are provided with overlapping projections to the left to be restored to hammer-locking position, and (3) a cam actuates said member prior to its action in withdrawing the hammer-retaining bail. The hammers 13 are loosely mounted on a shaft 4, Figs. 1 and 4, and are held in inoperative position by means of a bail 11 engaging a notch 12 in each hammer. An operation of the main-shaft, through a link 2, arm 3, and the shaft 4, rocks a cam 5 which is adapted to rock an arm 8 to withdraw the bail 11 to release those hammers which are not otherwise restrained. The hammers 13 are acted upon by a spring 16 attached thereto at one end and secured at the other end to a bar 17 carried on two slotted arms 18 mounted on a shaft 19 on the cam 5. Projections 22 on the hammers 13 are normally engaged by the shoulders 24 of the individual hammer-locking bars 23 which are pivoted on a shaft 25 and carry rollers 26 engaging a cam surface 27 on the type-bars 28. These hammer-locking bars 23 are provided with forward and lateral extensions 29, 30 and the right-hand locking-bar 23 is normally in engagement with a pin 31 of a bell-crank lever 32 pivotally mounted on the shaft 25 and held depressed by a spring 33. When the cam 5 is rocked, a roller 34 on the lever 32 raises the pin and thereby frees all the locking-bars and allows the type-bar 28 corresponding to the lefthand key depressed to release all the locking-bars to the right and ensures the printing of zeros to the right, the zeros in the normal position being opposite the printing line. The cam 5 on its return to the normal position, through the bar 19 restores the hammers which are thereupon locked by the bail 11 and by means of the spring 33 the lever 32 is depressed and causes the depression cf all the raised locking bars 23.

Title: Improvements relating to the refining of hydrocarbons by fractional distillation
IPC: C10C1/20
Filed: 1945-06-20
Abstract: Hydrocarbon oil fractions which have been washed with acid and then neutralised, are further refined by distillation in the presence of a small quantity of a substance soluble in the fraction and capable of reacting with acid to yield a neutral salt.  In the refining of a "light solvents" naphtha fraction with an end point of 170 DEG C., it is acid washed and neutralised, and then 0.2 per cent. by weight of pyridine bases which have been previously heated to 185 DEG C. to drive off lighter fractions, is added and the mixture submitted to distillation.  The addition of 0.1 per cent. of the same heavy pyridine bases to an acid-washed and neutralised coal-tar naphtha has been found to reduce the acidity formed on distillation by 50 per cent.  Sodium oleate and calcium resinate are also referred to as efficient corrosion inhibitors.

Title: Improvements in or relating to raking devices
IPC: A01D78/00
Filed: 1957-05-17
Abstract: 852,353. Haymaking machinery. VAN DER LELY N.V., C. May 17, 1957 [May 19, 1956], No. 15767/57. Class 6(3). A raking device comprises rake wheels mounted in echelon formation on a tractordrawn frame in such a manner that besides being rotatable about first horizontal axes passing through their centres, each wheel is also rotatable in one direction about a second horizontal axis which is transverse to the first, means being provided for preventing its rotation in the opposite direction about this second axis. Thus if the raking device is moved backwards, the wheels can assume a position in which they are inclined to the vertical, thereby avoiding extensive damage to the rake wheels, but when the device moves forwardly, rotation of the rake wheels out of their respective vertical planes is prevented. The frame of the rake comprises a frame member 7 supported by ground wheels 50 and 51, and to which are pivotally connected a drawbar 1 and two arms 8 and 9 supporting pairs of rake wheels 14, 15, 14<SP>1</SP> and 15<SP>1</SP>. The manner in which, for example, the wheels 14 and 15 are supported on the arm 9 is as follows : a pivot pin 21 carrying a bearing 19 (not shown) is mounted in the free ends of a U-shaped strip 16 secured to the rearward end of the arm 9, and to each side of the bearing is secured a plate 20. Two supporting members 23 are pivotally mounted at their upper ends between the plates 20, and at their lower ends are secured between two plates 26 which pivotally support a connecting member 27 having arms 31 and 32 on which the rake wheels 14 and 15 are mounted. Thus the rake wheels can rotate about the pivot pin 21 but such rotation is prevented in one direction by a strip 40 secured at its lower end to one of the plates 20, and urged towards the end of the arm 9 at its upper end by a spring 42. Adjustment of the rake wheels may be effected by pivoting the supports 23 relative to the plates 20, or by pivoting the member 27 relative to the plates 26, pins 37 and 39 respectively being provided for locking the members in the desired relative positions. The forward ends of the arms 8 and 9 are connected to strips 43 and 44 joined by a coupling rod 45 which can be moved longitudinally by rotating the crank 47, thereby adjusting the arms 8 and 9 in a horizontal plane relative to the member 7, means being provided for simultaneously adjusting the vertical axles of the ground wheels 50 and 51, and the angle of the draw bar 1. The construction may be modified as shown in Fig. 4, in which the rake wheels 58 and 59 can rotate in one direction about a pin 67 mounted in a fork 65 at the lower end of a supporting arm 62, rotation in the opposite direction being prevented by the arm 77 bearing against a stop 79. Specification 852,352 is referred to.

Title: Manufacture of products useful as textile assistants
IPC: C07D235/08
Filed: 1934-05-28
Abstract: Products useful as textile assistants, e.g. as foaming agents are obtained by substituting an alkyl or aralkyl residue for the hydrogen atom of the NH group of an amidine which is derived from a primary ortho or peri diamine and is substituted at the m  carbon atom by an aliphatic or hydroaromatic residue containing at least 8 carbon atoms.  The substitution may be effected by treating the amidines with alkylating or aralkylating agents or the diamines used as parent material for the synthesis may already contain the alkyl or aralkyl residue attached to the nitrogen. The alkyl and aralkyl residues introduced may contain hydroxyl or halogen.  In examples : (1) m -heptadecylbenzimidazole is heated with ethyl or allyl bromide or methyl, ethyl or butyl chloride ; (2) a mixture of m -pentadecyl- and heptadecylbenzimidazoles, obtainable from stearic acid and ortho phenylenediamine is heated with dimethylsulphate or benzyl chloride ; (3) m -heptadecenyl-benzimidazole obtained from olive oil and ortho phenylenediamine is heated with ethylene oxide or ethylenechlorhydrin ; (4) a mixture of benzimidazoles prepared from hydrogenated fish oil and ortho phenylenediamine is treated with ethylenechlorhydrin ; (5) m -heptadecyl-benzimidazole is heated with a -glycerinchlorhydrin or monochloracetic acid ; (6) a mixture of benzimidazoles derived from ortho phenylenediamine and hydrogenated fish oil, olive oil and coconut oil is heated with a mixture of glycerinchlorhydrin and ethylenechlorhydrin. The products may be used for the manufacture of sulphonic acids according to the processes described in Specifications 403,977 and 419,010.

Title: Improvements in and relating to the Extraction and Fractional Distillation of Oils from Coal-gas.
Inventor: MARBAIS DESIRE
IPC: C10G5/04
Filed: 1917-11-01
Abstract: 118,730. Marbais, D., and Deguide, C. Nov. 1,1917. Hydrocarbons, distilling.-Coal-gas is washed with an absorbent, the saturated absorbent is distilled for the regeneration of the absorbent, and the vapours obtained by distillation are divided into three fractions, namely. 90 per cent benzol, 50 per cent benzol, and a mixture containing naphthalene and an oil or spirit of the nature of solvent naphtha. The coal-gas is washed with tar oil or anthracene oil in a tower packed with wood shavings, metal waste, shavings or turnings of iron or steel, &c. The saturated absorbent is pumped through a preheater g into the top of a packed tower h, where it is distilled by steam. The residues leaving the base of the tower h are separated from water of condensation and are returned to the tower for washing the coal-gas. The vapours pass through a layer h<1> of packing at the top of the tower h and are led by a pipe h<3> to the preheater g, whence they emerge at a temperature of 95‹ C. After separation of the liquid, the remaining vapours pass through a cooling- coil k and a tower l, emerging at 79‹ C. The liquid condensing in the tower ! l and coil k is led back to a collector j, to which the liquid from the preheater g may also be led. This fraction is separated from water by decantation and consists of solvent naphtha and naphthalene, which separates in the form of crystals. A final tower from which the vapours escape at 70‹ C. separates from the remaining vapour a liquid consisting of 50 per cent benzol. The residual vapour yields 90 per cent. benzol upon condensation. The towers h, l &c. are packed with the same materials as the tower for washing the coal-gas.

Abstract: 122,666. Gray, B. P. Nov. 2, 1917. Hoof-supporting packing; renewable calks. - Relates to cross-bars carrying cogs, blunts, &c. and fitting immediately underneath the frog so that the pressure of the cogs &c. at the rear of the shoe will be taken by the frog. A roughing bar A carrying the cogs 9 is shaped to fit the space between the two sides of the shoe and is attached to the shoe by an inverted trough-shaped crossbar C which has turned-over edges 3, 4, Figs. 2 and 3. The end portions 5, 6 fit on the top of the shoe and are secured by rivets or other means. The roughing bar may otherwise be made in one piece with the crossbar, or be made in two pieces being divided transversely at the middle. Or instead of being fitted with cogs &c., the roughing bar may be formed with integral ribs. In a modification, the roughing bar A<4>, Fig. 14, is secured in an intermediate holder E, Fig. 27, which is itself secured to the cross-bar C by turned-over parts 20, 21. A stamped-out tongue 18 forms a catch for preventing the roughing bar from working forwards when in use. Or a set-screw or other means may be provided for that purpose. A spacing or thickness plate F may be interposed between the holder E and the roughing bar. The roughing-piece 15 is tapered at the ends and is passed from the top side of the roughing bar downwards through a corresponding slot with tapered ends. The thickness-plate F may be omitted and the roughing- piece 15 formed with a horizontal flange bearing directly against the face of the holder E. The roughing bar may otherwise be made of channel shape with flanges 27, 28, Fig. 22, embracing a spring bar 29, the free ends of which fit within the turned-over edges 16, 17 of the holder E. Or these parts may be made in one piece as shown in Fig. 23. In a construction in which there is no thickness-plate, the turned-over edge 20, Fig. 27, of the cross-bar C is made longer and acts as a stop to prevent the roughing bar A<4> working forwards. In a further modification, shown in Fig. 31, the roughing bar A<5> is secured directly to the cross-bar C by a turned over edge 3 and by a hinged piece 36 and screw 37. The roughing piece 15 may be secured in the slot in the roughing bar by the head of a screw 41, Fig. 32, bearing against the bottom of a recessed part 43. A rubber pad can be substituted for the roughing bar, being removably secured in the holder E.
