Title: Culinary mixes
IPC: A21D2/16
Filed: 1960-02-17
Abstract: A culinary mix which forms a baking batter with added liquid contains sugar, farinaceous material, and shortening, the shortening containing not more than 50% by weight of a fatty material which is solid at room temperature and contains 1.5 to 20%, based on the weight of shortening, of a fatty acid ester of a monomeric polyhydric alcohol, e.g. glycerol, glycol, sorbitol, mono- and di-saccharides, the fatty acid moiety of the ester being derived from a fatty acid having more than 20 carbon atoms in the molecule, e.g. behenic acid, or from natural oils containing such acids, e.g. rapeseed oil, herring oil, and having an iodine value not greater than 10, the alcohol portion of the ester containing at least one free hydroxyl group.  The fatty acid may be directly combined with the polyhydric alcohol and hydrogenated either before or after such combination; alternatively the partial esters may be made directly in combination with the shortening, e.g. suitable fatty acid triglycerides in admixture may be reacted with excess glycerine or subjected to random or directed rearrangement. The partial esters may also contain other residues, e.g. polyhydroxy carboxylic acids such as citric acid, tartaric acid, &c.  The preferred proportions of the essential constituents in the mix are, by weight, 28 to 45% sugar, e.g. sucrose, dextrose, maltose &c., 30 to 48% farinaceous material (of which up to half may be starch) e.g. bleached cake flour containing 50% at least of wheat flour, and 4 to 25% shortening, e.g. hydrogenated or unhydrogenated animal or vegetable fat and the mix may also include leavening agents, cocoa, egg solids, non-fat milk solids, flavouring, colouring, and emulsifiers, e.g. monostearin, sucrose partial oleate, monostearin phosphate, polyoxyethylene ethers of fatty esters.  Specification 797,034 is referred to.

Patent GB-1018031-A (GB)
Title: Polymers containing borazole rings
Inventor: GERRARD WILLIAM
IPC: C08G79/08
Filed: 1961-02-16
Abstract: Linear polyborazolenes consisting of borazole rings directly connected from boron to nitrogen, those boron atoms which are not connected to another ring carrying R1R2N groups in which R1 and R2 are alkyl, cycloalkyl, aralkyl or aryl, are prepared by heating an appropriate B,B1, B11-tri (R1R2N-substituted) borazole at a temperature not exceeding 300 DEG  C. to eliminate R1R2NH.  Heating at a higher temperature in excess of 350 DEG  C. leads to further elimination of R1R2NH and formation of a cross-linked, thermally stable polymer.  The polymers may be formed by heating, for example, mixtures of di-s-butylamine with B,B1,B11 - trichloroborazole, or with B,B1,B11-tri (dimethylamino) borazole.  In examples, polymers are produced by heating (1) B,B1,B11-tri (diethylamino) borazole first at 250 DEG -280 DEG C. and then at 400 DEG C.; (2) B,B1,B11-tri (di-iso-propylamino) borazole at 200-230 DEG C.; (3) B,B1,B11-tri (diphenylamino) borazole to about 500 DEG C.; (4) a viscous reaction product of di-s-butylamine and B,B1,B11-trichloroborazole at 300 DEG C.; (5) di-s-butylamine with B,B1,B11-tri (dimethylamino) borazole with removal of dimethylamine and di-s-butylamine.  The polymers are useful as coating materials particularly for electrical insulation and when high-temperature resistance is needed.  Films and mouldings of the polymer may be produced.

Title: Method for the treatment of molten non-ferrous metals by blowing with reaction gases
IPC: C22B15/00
Filed: 1974-02-08
Abstract: 1457175 Refining metals W WUTH 8 Feb 1974 [9 Feb 1973] 05951/74 Heading C7D In a method of removing impurities from molten metals, such as copper, oxygen or oxygen enriched air reaction gas is blown on to the metal surface from at least one gas jet, mounted approximately perpendicularly to the molten metal surface, with such a force that the melt rotates in a torus-like manner, bringing fresh metal from the bath depth to the surface where it can react with the gas. The reaction rate is determined by the jetpressure and the nozzle-to-bath distance, and optimum results are achieved where these two factors are adjusted so that minimal splashing occurs. Approximate values for blast impression depths for oxidizing and reducing copper are given as 1À8 and 1À5 cms. respectively, and the use of convergent/divergent nozzles instead of the normal convergent nozzles is recommended.

Title: Improvements in or relating to percussive tools
IPC: B25D9/10
Filed: 1947-03-03
Abstract: 622,709. Percussive drills. CHICAGO PNEUMATIC TOOL CO. March 3, 1947, No. 5983. Convention date, Aug. 15, 1946. [Class 124] [Also in Groups XXIV and XXVII] In a percussive tool driven by an internal combustion engine, having a first crankshaft driving a second crankshaft, a hammer assembly, including a hammer piston reciprocating within a sliding member, reciprocates in a barrel member mounted on the tool housing, connecting means from the second crankshaft transmitting reciprocating motion to the hammer assembly, and a collared working implement, receiving intermittent blows from the hammer piston, arranged within the barrel. As shown a hammer piston 19, slidingly arranged within a cage 20 which is reciprocated by a connecting rod 24 driven by a crankshaft, delivers blows on a steel 18 having a collar 42 mounted in the space between two snubber rings 32 and 35 separated by a flange 33. The snubber rings are maintained in contact with the flange 33 by springs 31 and 36 which also cushion any excess movement of the steel. A chamber 52 above and a chamber 53 below the cage 20 are connected by passages and ports and may have ports to the atmosphere. The piston 19 has a cupshaped recess 59 which loosely receives a depending portion 56 of the cage head. The upward movement of the cage causes a vacuum in a space 57 and results in the upward movement of the piston, the downward movement of the cage compressing the air in the space 57 and causing the piston to deliver a blow on the steel. One of the handles of the tool may operate a starter for the internal combustion engine and may be locked in a position against the body of the tool Fig. 1 (not shown).

Title: A combination of a direct-current motor, a hall-effect resolver for energising the motor and negative feedback circuitry
IPC: H02K29/08
Filed: 1970-02-09
Abstract: 1292719 Servo electric control systems THOMSON-CSF 9 Feb 1970 [17 Feb 1969] 6164/70 Heading G3R [Also in Division H2] A tachometer negative feedback device is combined in one machine with a Hall effect resolver and D.C. motor, for use in a servocontrol system. As shown Fig.1a, the resolver has a stator ring 1 of soft magnetic material and carrying Hall generators 3, 4 spaced by #/2 electrical degrees or #/2p angular (where p is number of pairs of poles on a rotor 2). The rotor 2 is common to the resolver and motor and comprises a laminated core in which permanent magnets 20 are embedded. The motor stator is solid with the resolver stator and comprises a laminated core 50, Fig.1b with slots carrying two coils. Each motor coil forms a multi-polar winding with 2p poles. The motor coils are displaced from one another by #/2 electrical degrees. The tachometer negative feedback device comprises two identical coils 5, 6 on the stator ring 1 at 2#/3 and #/6 + #/3 angular intervals respectively from the reference radial plane OX and thus from the Hall generator 3. In operation, the Hall generators 3, 4 produce sine, cosine voltages proportional to the control current Ig through them and with respect to the angular position of the rotor (angle between OX and OY). The tachometer coils 5, 6 produce alternating voltages proportional to the rotor speed. As shown, Fig.3, the negative feedback voltages of the tachometers are applied in opposition to the Hall generator voltages and the amplified difference voltages in phase quadrature feed the motor coils 12, 13. Thus tachometric negative feedback is produced without a supplementary machine. Potentiometers may be used to adjust the tacho voltages, Figs.4a, b, c (not shown). Alternative angular positions of the coils may be selected.
