Abstract: 668,215. Photographic emulsions containing colour couplers. ILFORD, Ltd. Nov. 27, 1950 [Nov. 4, I949], No. 28293/49. Class 98 (ii). A light-sensitive gelatino silver halide emulsion contains a proportion of a complex separately formed between gelatin and a colour coupler which is a sulphonic acid having a highly hydrophobic anion, the amount incorporated being sufficient to achieve a suitable colour coupler/silver ratio for colour formation by colour development. In a modification, two separate emulsions may be formed, one from a gelatin/colour coupler complex and the other from a gelatin/anion soap (or a non-colour-forming sulphonic acid having a highly hydrophobic anion), each containing suspended silver halide, and such emulsions may then be blended in suitable proportions. Alternatively, a complex may be formed between gelatin and a mixture of colour coupling sulphonic acid and anion soap or non-colour forming sulphonic acid having a highly hydrophobic anion. In example 1, an aqueous solution of 1-hydroxy-2-naphthoyloctadecylamide-4-sulphonic acid is added to an aqueous gelatino silver iodobromide emulsion containing ammonium nitrate. The sedimented complex is redispersed in warm water, warm aqueous alcohol, warm gelatin solution, methanol, or ethanol, and is blended with an ordinary emulsion. In example 2, the procedure is similar, using a mixture of the colour coupler and aqueous Aresklene 375,. In example 3, the procedure is similar to example 1, using an emulsion containing ammonium nitrate, ammonium bromide and ammonia, and re-dispersing the complex in an aqueousethanol gelatin solution. In example 4, the procedure is similar to example 3, using a. mixture of colour coupler and " Teepol" (Registered Trade Mark). Specifications, 580,504, 585,758, 585,759 and 651,318 are referred to.

Title: A process for the preparation of beta-ether-substituted propionaldehydes
Filed: 1960-08-17
Abstract: A catalyst for use in the reaction between an alcohol and acrolein to give a b -ether substituted propionaldehyde consists of a mixture of at least one b -alkoxycarboxylic acid and at least one alkali metal salt of such an acid, there being present at least 0,25 mole of salt per mole of acid.  The catalyst may be prepared in situ by adding an alkali metal hydroxide to the b -alkoxycarboxylic acid.  The acid may be mono-or polycarboxylic but the preferred acids are b -alkoxypropionic acids.ALSO:b -Ether-substituted propionl aldehydes are prepared by reacting an alcohol in the liquid phase with acrolein in the presence of a mixture of at least one b -alkoxycarboxylic acid and at least one alkali metal salt of such an acid, there being present at least 0.25 mole of salt per mole of acid.  Suitable alcohols are, for example, straight or branched-chain, saturated or unsaturated aliphatic alcohols, diols, cycloaliphatic alcohols, e.g. cyclohexanol alcohols substituted by aromatic groups, e.g. benzyl alcohols, alicyclic substituted alcohols, e.g. 2-cyclohexyl-ethan-1-ol, and ether-alcohols, such as alkoxy alcohols, 2-(2-methoxy-ethoxy)-ethanol, 2-allyloxyethanol, 2-benxyloxy-methanol, 2-phenoxyethanol, and diethylene glycol. The mixture of acid and salt used as catalyst may be prepared in situ. The preferred temperature range for carrying out the process is 10 DEG C.-60 DEG C.  It is desirable to use an excess of the alcohol to get maximum conversion.  The catalyst should preferably be present in an amount of at least 1% of the total weight of the reaction mixture. The b -ether substituted propionaldehydes may be separated by distillation.  The products may be converted to b -ether-substituted propionic acids by oxidation in the liquid phase with molecular oxygen in the presence of a polyvalent metal oxidation catalyst, e.g. one or more of the metals manganese, cobalt, copper or nickel, or compounds thereof, at a preferred temperature of 40 DEG C.-70 DEG C.

Filed: 1926-11-13
Abstract: 285,160. Kennedy, D. Nov. 13, 1926. Elements moving always in one plane, rotating.-A sign of the type in which pictures, letters &c. are built up from movable elements comprises a base member on which are mounted discs or portions of letters &c. in such a way that the whole of the display matter can be seen at all times, and means for positively rotating the disc &c. The display matter may be carried partly on the fixed base, Fig. 5, or the sign may be made to display different matter successively, Fig. 6. The same operating mechanism can be used for two signs arranged back to back. The sign may be normally blank, the desired display matter being written on it as on a blackboard. As shown, discs 23 are rotated intermittently and preferably at different speeds and are made to pause for a longer period in the display position. The discs are driven by chains &c. from a wheel 14 loosely mounted on a shaft 10 and carrying a disc provided with three equidistant pins 13. An arm 11 driven by an electric motor carries at one end a pivoted member 12 which first, comes into contact with a fixed cam 15 and is thus swung clear of the pin 13 adjacent this cam, travels to the next pin and then drives the wheel 14 120‹, is finally swung clear of this pin by the cam 16 and then of the next pin bv the cam 15 to begin a new cycle. At each revolution, teeth 25 on the other end of the arm 11 engage a ratchet wheel 26 carrying a cam member 28. When the elements are in display position, the cam 28 is in the path of the member 12 and disengages it from the pin 13 that it is about to drive. The arm 11 thus makes a further complete revolution without driving the advertisement elements which are held during this period by a spring 29 which engages a notch in the disc 14. According to the Provisional Specification the disc on the wheel 14 has only a single pin and is driven by a constantly rotating disc having three pins. A constantly driven cam moves the first mentioned disc axially until the pin is clear of the pins on the seconds disc to provide a dwell. The discs which may overlay more or less are latched separately in the display position the latches being controlled by a constantly driven cam.

Filed: 1950-11-23
Abstract: 689,920. Alternators. ELECTRIC CONSTRUCTION CO., Ltd. Oct. 31, 1951 [Nov. 23, 1950], No. 28698/50. Class 35. The output voltage of an alternator is kept constant by means of a bucking winding fed from a rectifier connected in series, across the output leads, with a choke which is saturated at all values of output voltage. The bucking winding may be applied directly to the alternator but in the form shown the alternator field winding F is energized by an exciter E which carries the bucking winding DF in addition to its shunt field winding EF. The voltage drop across the choke L is constant due to saturation and is the greater part of the normal alternator voltage so that the voltage variation across the rectifier R feeding the bucking winding is very responsive to voltage fluctuations.

Abstract: 1,073,775. Textile treating apparatus. BRAD FORD DYERS' ASSOCIATION Ltd. July 15, 1964 [July 19, 1963], No. 28726/63. Heading D1L. In a treatment process in which wet carpet having a woven backing is caused to travel in deep loops that extend from horizontal rollers, the formation of creases in the carpet is prevented by the application to the back faces of the upward runs of the loops, of forces acting both upwards and outwards on each side of the centre line of the carpet. In the apparatus shown carpet enters the chamber 1 through an inlet 2, travels through the chamber in a series of deep loops 3 which extend downwards from horizontal rollers 4 and leaves through outlet 5, passing through washing bath 6 and finally between rollers 7. Throughout the lower half of each upward run the backing is engaged by endless rope conveyors 8 passing around upper rollers 9 and lower rollers 10 said rollers being driven by chain drives 25, 26 from the shaft of the respective roller 4. The latter is driven from shaft 20 through infinitely variable speed gear 23. The runs of the rope conveyors 8 are arranged such that they are spaced further apart on top roller, 9 than they are on bottom roller 10, so as to produce a spreading action on the carpet. This spacing is done by means of spaced guides 14, 15 or by spaced grooves in the respective rollers. Each rope conveyor 8 may be formed of a number of separate endless loops or of a single continuous rope in spiral formation around the rollers and preferably the rope speed is arranged to be 10 to 15% faster than the carpet speed. An additional conveyor may be provided on the upper half of each upward run of carpet.
