Abstract: 390,118. Extracting gluten from flour. BIECHY, T., 129, Thalhauserstrasse, Freising, Oberbayern, Germany. Dec. 30, 1932, No. 36914. [Class 58.] To determine the quality of flour by extracting the gluten therefrom a lump of dough is made from 10 to 20 grammes of flour and d about half the quantity of water and is placed on a doughsupporting surface b adjustably mounted between four supporting brackets c and consisting of a piece of cloth, fine gauze, porous rubber sheet or other material through which water may pass ; the dough is kneaded by a member comprising a bell l carried on a hollow stem m mounted by a crank arm r on a rotating shaft s. The wide lower end of the bell is closed by a metal disc having a concave lower surface carried by a friction pad o of roughened rubber, leather or wood. Water from a tank d is allowed to drip through a passage in the shaft S into a funnel at the top of the stem m passing through the stem and the kneading member to the dough. The stem m is rotatable and axially displaceable in, the arm r and after the dough has been kneaded for about three minutes so that its outer layer is freed from gluten the kneading member starts to rotate about its own axis rotating the dough so that new surfaces are presented for treatment ; all the gluten collects at the middle of the surface b in about seven or eight minutes and can be removed. The water drains through the cloth into a receptacle g. A flange z on the shaft s is adapted to engage a lug y on the stem m to hold the kneading member in a raised position when required.

Title: A process for the production of salts of aromatic or heterocyclic carboxylic acids
IPC: C07C51/41
Filed: 1956-12-06
Abstract: Alkali metal salts of carboxylic acids, where the carboxyl groups are directly attached to an aromatic ring system or a heterocyclic ring system of aromatic character are prepared by heating alkali metal salts of aromatic or heterocyclic carboxylic acids other than those to be prepared in the presence of inert solid substances whose particle size is less than 50 m .  The inert substances mentioned include activated carbon, silicic acid, kieselguhr, alumina, metals and metalloids and their oxides and salts such as sulphides, carbonates, silicates or phosphates. Their particle size is preferably below 1 m  and they may be added to the reaction mixture to an extent of between 0.05 and 50 per cent.  The reaction may take place at about 200-500 DEG  C., preferably in an inert atmosphere and metallic catalysts and other inert material may be added to the mixture if desired.  The reactants may include carboxylic acids of benzene, naphthalene, diphenyl, pyridine, pyrazine, pyrimidine, pyridazine, a -pyran, furan, thiophene, pyrrole, thiazole, quinoline, isoquinoline, indole, benztriazole and benzimidazole.  Mixtures of acid anhydrides and alkali metal carbonates may also be used.  In the examples terephthalic acid is obtained with lesser amounts of trimesic acid and benzoic acid by heating dipotassium phthalate in the presence or absence of the usual catalysts, e.g. CdF2, in the presence of activated carbon, nickel oxide obtained by burning Raney nickel, nickel obtained by reducing the decomposition product of nickel nitrate, copper, powdered electrolytically, and silica; similar products are obtained by heating a mixture of phthalic anhydride and potassium carbonate with alumina, and silicic acid, tripotassium hemimellitate and activated carbon, potassium benzoate and nickel oxide and dipotassium isophthalate and activated carbon; naphthalene 2 : 6-dicarboxylic acid is obtained by heating potassium b -naphthoate in the presence of silica.  Example (7) gives a comparison between reaction carried out in the presence of (a) quartz of particle size 5 to 50 m , and (b) coarse quartz sand.

Abstract: 952,273. Hydraulic accumulators. GREER HYDRAULICS Inc. Oct. 8, 1962 [Nov. 1, 1961], No. 38037/62. Heading F1P. One of a pair of containers 11, 12 comprising a fluid pressure accumulator is provided with a deformable partition, such as a bladder 41, which divides the container into gas and liquid chambers and a porous guide member 58, the two containers being interconnected so that gas forced into the container 12 can pass into the gas chamber of the container 11 to expand the bladder. The guide member 58, which serves to prevent undue collapse of the bladder, is formed with perforations 64 and covered with a sleeve 66 of porous material such as sintered bronze. The guide member is mounted on a sleeve 43 which is secured in the port 14 of the container 11, the sleeve having a flange 49 which coacts with a ring 53 for gripping the mouth of the bladder when the securing nut 48 is tightened; the ring 53 is bonded to a resilient seal 551. The containers are interconnected by means of a tubular member 71 which is screwed on to the sleeve 43 and provided with a shoulder 73 and a nut 79 for tightening it to the port 15 of the gas container 12; a tubular member 17 housing a valve 28 is similarly sealably-secured in the oil port 13 of the container 11, the ring 21 in this case being bonded to a seal 36. To pre-charge the accumulator, a controlled quantity of gas is forced into the container 12, the bladder 41 thereby expanding and closing the valve 28 over the oil port. Fluid is then admitted through the port to compress the bladder and increase the pressure therein. When the accumulator is in operation, any leakage of gas from the bladder will cause the bladder to collapse and after the bladder has collapsed sufficiently to be supported by the guide member 58, the leakage can be detected by a difference in pressure readings on gauges in communication with the liquid chamber and the gas container 12.

Abstract: 876,666. Colour television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 11, 1957 [Dec. 14, 1956], No. 38164/56. Class 40(3) Relates to an arrangement for modifying a colour ratio subcarrier signal of frequency w of the form The original signal, Fig. 2a, varies in amplitude in accordance with hue such that the vectors 1, 2 and 3 representing respectively saturated red, blue and green are in the ratio 1:3:0À565, whereas the corresponding vectors 4, 5 and 6 of the modified signal, Fig. 2b are of equal amplitude. In the circuit for carrying out the invention, Fig. 1, the original signal E c  is applied to an amplifier 7 the gain of which is varied by a control signal in accordance with the hue in such manner that the amplitude variation is removed and the desired modified signal is established. The control signal is obtained by applying the original signal to a limiter 8 to obtain a signal varying only in phase in accordance with hue and then sampling the signal in gate stages 9, 10 and 11 at angles of 270 degrees, 30 degrees and 150 degrees respectively. The gate outputs represent respectively -0À87B+0À87G,0À87R-0À87G,-0À87R+0À87B, where R, G and B represent the primary colour co-ordinates. A matrix 12 derives signals representing R, B and G and these are then applied through amplifiers 13, 14 and 15 having gains of 1, 0À33 and 1À77 respectively. The final signals are combined in adder 16 and form the control signal. In an alternative way of carrying out the invention there is added to the original signal after its passage through a limiter, a biasing oscillation 20, Fig. 2c, of frequency w, the amplitude and phase of which are selected so that the resultant vectors 21, 22, 23 for red, blue and green are in the approximate ratio 1:0:33:1À77. A simple amplitude detector may then be employed to derive the control signal. In practice this arrangement permits only an approximate modification. An improvement may be obtained by repeating the process in a second identical arrangement. The invention may be employed in receivers as described in Specifications 871,367 and 877,766. Where it is desired to convert an accompanying luminance signal E Y  into an equi-energy signal E E  this may be done as described in Specification 6575/57. Specifications 863,604 and 864,452 also are referred to.
