Abstract: 997, 254. Automatic speed control. SECRETARY OF THE ARMY [Representing the GOVERNMENT OF THE U.S.A.]. Oct. 2,1962 [Oct. 3,1961], No. 37287/62. Heading G3R. [Also in Division H2] Generator-motor groups 1,2, and 1<SP>1</SP>, 2<SP>1</SP>, drive opposite tracks or wheels of a vehicle, the generators 1,1<SP>1</SP>, being mechanically coupled to a single prime mover. Field windings 8 of motors 2 are connected in series through amplidyne 7 and reversing switch 6 to field winding 5 of generator 1, the amplidyne having field winding 9 across shunt 3 in the armature circuit. Relay 10 responds to reversals of armature current and prevents reversal of current in winding 9. When the vehicle is being driven, motor field windings 13 are excited from battery 15, and generator field winding 14 by exciter 17, the speed of the vehicle being controlled by potentiometer 18 associated with control winding 19 of exciter 17. Potentiometers 21, 21<SP>1</SP>, are coupled to shaft 22 and connected to exciter windings 23, 23<SP>1</SP>, to control the relative speeds of the two motor-groups for steering the vehicle. Actuation of switch 24 introduces regenerative braking, field windings 13 being supplied from exciter 17 and field winding 14 from battery 15. Potentiometer 26 is connected to braking field windings 27, 271, of exciters 17,17<SP>1</SP>. If the prime mover overspeeds during braking operation, centrifugal switch 30 actuates relays 31, 31<SP>1</SP>, to introduce braking resistors 32, 32<SP>1</SP>. The vehicle is turned to the right by moving bar 57 to the left so displacing friction wheels 54, 54<SP>1</SP>, which engage friction plates 51, 51<SP>1</SP>, driven from opposite sides of the vehicle. The wheel 54<SP>1</SP> rotates faster than the wheel 54 so that differential gear 56 turns shaft 22 in a sense to accelerate the motors on the left and decelerate those on the right. As the vehicle turns, the speed of plate 51 increases in relation to that of the plate 51<SP>1</SP> until the wheels 54, 54<SP>1</SP>, rotate at equal speeds and shaft 22 reaches a stable position. The steering potentiometer combination also responds automatically to undesired deviations of relative speed, so as to equalize the speeds of the two motor-groups.

Title: Proteinaceous material and method of preparing same
IPC: A23J1/10
Filed: 1958-11-24
Abstract: A non-gelling hydrolysed proteinaceous material is prepared by separating the material from an aqueous solution of the material formed by hydrolysis of collagen-containing matter by mixing the aqueous solution with a water-miscible precipitating agent in sufficient quantity to precipitate at least a major portion of the proteinaceous material and recovering the precipitated protein from the precipitating agent-water solution.  The precipitating agent may be an aliphatic monohydric alcohol e.g. methyl, ethyl or isopropyl alcohol, a ketone of low molecular weight e.g. acetone or methyl ethyl ketone, or mixtures thereof, the alcohol being employed in a concentration in the range 80 to 95% alcohol.  The mixing may be performed while the temperature is maintained between 0 DEG  and 75 DEG F. and may be performed counter-currently under conditions such that the precipitated protein is washed. while settling, by fresh precipitating agent. The recovered precipitated protein is dissolved in water and the resulting solution is steam-stripped to remove traces of precipitating agent.  The aqueous solution may be bleached with a bleaching agent capable of freeing nascent oxygen, prior to mixing the solution with the precipitating agent.  The aqueous solution may be concentrated e.g. to between 45 and 75% dissolved solids by weight, prior to bleaching.  The pH of the aqueous solution may be adjusted to an alkaline pH e.g. 8.0 to 12.3, and the aqueous solution may be heated e.g. at 85 DEG  to 100 DEG C., for a time sufficient to destroy peroxidase e.g. 30 to 60 minutes prior to bleaching.  The pH may be adjusted with ammonia, ammonium hydroxide, oxide, hydroxides or carbonates of alkali metals, or an oxide or hydroxide of an alkaline earth metal e.g. barium hydroxide or lime. The pH of the bleached solution may be adjusted to a pH less than 7 prior to mixing with the precipitating agent e.g. with an acid such as sulphuric, tartaric, or phosphoric acid, which forms a water-insoluble salt of alkaline earth metals, the precipitated insoluble salt being separated from the bleached aqueous solution prior to mixing with the precipitating agent.  The separated solution may be concentrated to a solute content of between 30 and 60% by weight prior to mixing with the precipitating agent.  The bleaching agent may be a peracid, sodium or barium peroxide, or hydrogen peroxide in a quantity of 5 to 11% by weight of protein solids, the solution being maintained at a temperature of 21 DEG  to 95 DEG C. during bleaching.ALSO:A food adjunct which has foaming properties and is a non-gelling proteinaceous material is prepared from an aqueous solution formed by hydrolysis of collagen-containing matter by mixing the aqueous solution with a water-miscible precipitating agent, e.g. methanol, in sufficient quantity to precipitate at least a major portion of the proteinaceous material (see Group IV (b)).  The material may be added to beer, and may be used in the preparation of frapp<\>aes, nougats, fudge, cream candies and cake frostings.

Title: A process for the selective hydrogenation of liquid hydrocarbons
IPC: C10G45/40
Filed: 1961-10-27
Abstract: Liquid hydrocarbons of the gasoline boiling point range, i.e 30 DEG -200 DEG C., are catalytically hydrogenated whilst trickling them over a hydrogenation catalyst carried on a macroporous support, which has an intrinsic surface area of less than 50 m2/g. and a water absorption capacity of at least 10% by weight in a reaction chamber, wherein only the first part, preferably at least one quarter, of the reaction chamber is maintained at a temperature below 50 DEG C., preferably 25 DEG -35 DEG C., the temperature in the remainder of the chamber being allowed to rise up to 100 DEG C., for example to 75 DEG C.  The catalyst may be a noble metal of Group VIII of the Mendel<\>aeeff Periodic System of the Elements, for example platinum or palladium, which may be present on the support in an amount of 0,05-5% by weight.  The liquid hydrocarbon may be a cracked gasoline obtained from the pyrolysis of liquid or liquefiable hydrocarbons, and are preferably free from hydrogen sulphide and easily decomposable organic sulphur compounds. These may be removed by trickling the hydrocarbon down a column up which a hydrogen sulphide-free gas is passing, or by distilling off the lighter fractions.  Suitable supports include lightly baked clay free from, or containing only a small quantity of, iron, for example broken pieces of clay plates, pumice stone free from iron, weakly sintered aluminium oxide, magnesium oxide obtained by heat treatment of iron-free magnesite, and charcoal free from tar which may have been treated with steam under mild conditions.  In an example, alumina in the form of cylinders was sintered at 1300 DEG C., saturated with palladium chloride, and reduced by hydrazine hydrate.  Suitable hydrogenation conditions include an hourly throughput of feedstock of 4-15 kg./litre of reaction chamber, and a hydrogen pressure of 10-50 atmospheres.
