Title: Improvements in machines for moulding or preparing dough for making bread and the like
IPC: A21C3/00
Filed: 1930-12-17
Abstract: 363,131. Dough rolling and working. JONES, A. and JONES, W. H., (trading as EDWARDS & JONES), Cooke Street, Longton, Stoke-on-Trent. Dec. 17, 1930, No. 37994. [Class 87 (ii).] A machine for moulding dough comprises a horizontal travelling belt a and a further belt c, arranged to travel at a transverse angle to the direction of travel of the first belt, and mounted so that, transversely, it is inclined to the plane of the horizontal belt. The belt c is supported by a backing plate b having a bead b<1> to guide the belt which runs on rollers e pivotally mounted so that the angle of inclination between the belts can be varied. The angle is provided with a curved plate d which prevents the pieces of dough from being nipped. The belt c, which may be of rubber and may have its outer face curved or shaped to mould the dough, travels in the direction of the arrow c<1>, opposite to that of the belt a, and at a greater speed than this belt so that pieces of dough placed on the belt a are brought into contact with the belt c which carries them backwards and delivers them at the end f of the machine.

Filed: 1972-08-16
Abstract: 1396744 Selecting records RICOH KK 16 Aug 1972 [14 Sept 1971] 38111/72 Heading G4M Relative movement between sheet storage means 2 and a reading station 20-24 causes the sheets to be displaced in succession to a read-out position at which the reading station can sense coded indicia on the displaced sheet. In the embodiment shown, rod-like extensions 16 which are formed on a clip 3B attached to each sheet, e.g. microfiche, are engaged between and magnetically attracted to the teeth of endless belts 18, and the belts 18 pass over a roller 19 so that each sheet is raised in succession and a coded marginal portion of the sheet located in a cut-out portion of the clip 3B is raised into the sensing light beam. In another embodiment, the storage means is formed with a rack-like upper surface for supporting the rods 16 between the teeth, and a star wheel, engaged by the underside of the rods, raises the sheets in turn. Magnets may be used to raise and return the sheets instead of the star wheel. A selected sheet may be detected by comparison of its code with a keyed in code, the sheet then being withdrawn for display and/or copying.

Patent GB-840320-A (GB)
Title: Improvements in or relating to a process for the production of naphthalene-aldehyde condensation polymers
IPC: C08G10/02
Filed: 1956-12-14
Abstract: Acid catalysed naphthalene aldehyde resins, after being purified by known methods to remove the catalyst and by-products, are treated at a temperature of at least 120 DEG  C. (preferably 150-250 DEG  C.) with a gas which is inert to the resin so as to remove uncondensed naphthalene, said gas comprising CO2, CO, H2, hydrocarbon or N2 or any mixture thereof.  The treatment has the effect of raising the softening-point of the resin, as well as removing the smell of naphthalene.  Acid catalysts mentioned are H2SO4, borofluoric acid and BF3.2CH3COOH, the last of which is later neutralized with ammonia; the preferred aldehyde is formaldehyde; and specified hydrocarbons are methane and ethane.  The initial purification may be carried out by washing with water, dissolving in aromatic hydrocarbon, discarding the aqueous fraction, treating the hydrocarbon fraction with a bleaching-agent and finally distilling off the solvent.  The gas treatment may be carried out by bubbling the gas through the liquid resin.  After-treatment.-Such resins may be heated with polymerizable unsaturated hydrocarbons such as styrene, coumarone, indene and cyclopentadiene, either at the same time as, or after, the uncondensed naphthalene is removed. Uses.-Lacquers, paints, floor stains, printing inks, sealing waxes.

Abstract: 981,057. Slip rings for dynamo-electric machines. BROWN BOVERI & CO. Ltd. Oct. 2, 1963 [Oct. 4, 1962], No. 38750/63. Heading H2A. In a wound rotor induction motor the slip rings are short-circuited by contacts (not shown) carried by sleeve 2 which is axially moved by block 3 engaging with groove 1 in the sleeve. Movement of the sleeve is transmitted to cam 9, pivoted at 8, by means of auxiliary block 4 which closely fits groove 1 so that inductor lamp 12 is turned off when follower 10 engages the slot in the cam face. If block 3 is worn, cam 9 will not rotate far enough for the follower to engage the slot and lamp 12 will remain alight. In a modification the pivotable link arm to the auxiliary block is extended beyond its fulcrum and this extension used to operate an indicator switch. The indicator may be interlocked with the motor starting switch so that the motor cannot be operated again until the block is replaced.

Abstract: 1313078 Purifying sugar solutions SOC ITALIANA PER L'INDUSTRIA DEGLI ZUCCHERI SpA 25 Aug 1971 [27 Aug 1970] 39969/71 Heading C6B  A sugar extraction process comprises the steps of extracting juice from sugar beets, acidifying the juice, separating the precipitates formed as a consequence of the acidification, and then, after cooling the juice, treating it in succession with cationic and anionic type ion exchange resins, followed by concentration of the juice to a syrup, and crystallization. An additional treatment with an anionic type ion exchange resin may be performed before the treatment with the cationic type. Juice extraction may be performed by conventional diffusion methods or by mechanical squeezing, and the subsequent acidification, to bring the pH of the juice to the range 3À5 to 4À0, is effected by the additon of an organic or inorganic acid or by recycling part of the juice from the cationic resin stage. Separation of precipitates is performed by filtration, centrifugation or by static or dynamic decanters, or by combinations of these methods, and organic or inorganic coagulating agents may be used. The cationic type resin with which the juice, after being cooled to the range 8‹ to 18‹C, is then treated is preferably of strong type, regenerated in acid form. The anionic type resin used in the next step is preferably of weak or medium strength, and may be followed by treatment with a strong anionic type resin in hydroxylic form. Before the juice is concentrated and crystallized it may be subjected to decolouring by activated charcoal etc.

Title: Process for recuperating oxime from oximisation waste solution, at the same time utilising the hydroxylamine sulphates contained therein
Filed: 1959-12-01
Abstract: An oximation waste solution, obtained during the production of a cyclo-aliphatic ketoxime, is treated for the recuperation of oxime and for utilization of hydroxylamine sulphate contained therein by mixing the still hot waste solution with a sufficient quantity of the cyclo-aliphatic ketone used in the oximation, passing the mixture through a cooling system and separating the resulting solution of oxime in the cyclo-aliphatic ketone from the waste solution which then contains ammonium or alkali metal sulphate freed from oxime and hydroxylamine sulphate.  The oximation waste solutions are those obtained in the production of the ketoximes by reacting appropriate ketones with a hydroxylamine sulphate solution, which itself has been produced by a process using alkali metal or ammonium nitrites or bisulphites, the mixture being neutralised e.g. with ammonia.  The oximation mixture may contain melted oxime and a 40-42% ammonium sulphate solution at 85-95 DEG C., and the melted oxime may be separated from the ammonium sulphate solution while still hot.  The treatment of waste solutions obtained in the production of cyclohexanone oxime and o-methyl cyclohexanone oxime is described.
