Title: Improvements in the manufacture and production of colour lakes
IPC: C09B69/06
Filed: 1930-04-12
Abstract: Colour lakes are manufactured by treating the colour lakes of basic dyestuffs and inorganic heteropoly acids with reducing agents, such as sodium hydrosulphite, sodium bisulphite or nascent hydrogen formed by the action of zinc dust on the acid precipitating bath.  The treatment may be carried out in the presence of substrata, and the lakes after reduction may advantageously be heated for a short time in the bath.  In examples: (1) Methyl Violet B is precipitated on a substratum of hydrate of alumina by a solution of the acid sodium salt of phosphotungstic acid and the product reduced by sodium hydrosulphite and afterwards heated to 90 DEG  C., yielding a violet lake; (2) Diamond Green GX is precipitated by a solution of the acid sodium salt of phosphotungstomolybdic acid or of the components thereof, the product reduced by the addition of zinc dust or sodium bisulphite solution, and the whole then boiled for half an hour.

Title: Method of introducing silicon-bonded hydrogen into organopolysiloxanes
IPC: C08J3/28
Filed: 1961-04-04
Abstract: Silicon-bonded hydrogen is introduced into an organopolysiloxane by irradiating with ionizing radiation a mixture of (1) a siloxane of the general formula RmSiO 4-m/2 , wherein each R is an alkyl, cycloalkyl, aryl, alkaryl, aralkyl, haloaryl, haloalkyl or cyanoalkyl radical, at least 50% mol. of the radicals being methyl or ethyl radicals, and m has a value of from 1.98 to 3, and (2) a minor proportion of a hydrogen transfer mercapto compound free of olefinic unsaturation.  Compounds (2) specified are ethyl-, n-butyl-, m-amyl-, n-octyl-, n-dodecyl-, t-butyl-, t-octyl, naphthyl-, phenyl-, benzyl- and b -ethoxypropyl-mercaptans, ethylthioglycolate, thiophenol, 2-mercaptobenzothiazole, mercaptoacetic acid, thioglycollic acid, glycoldimercaptoacetate, <FORM:0974349/C3/1> The mercapto compound is generally used in amount of 2 to 30% by weight of the siloxane. Solvents may be used to effect homogeneity of the siloxane and mercapto compound.  In a typical example (1), a solution of dodecyl mercaptan in a liquid dimethylpolysiloxane was placed in a receptacle in an atmosphere of nitrogen, and was then irradiated with high energy electrons to yield, on purification, a methylpolysiloxane containing Si-H groups.

Title: Improvements in or relating to Apparatus for Testing or Separating Coins.
Inventor: HIRD FRANCIS
IPC: G07D5/08
Filed: 1916-08-31
Abstract: 103,085. Hird, F. Aug. 31, 1916. Coins, separating; coins, testing.-Relates to apparatus for separating coins, in which the coins are projected through a magnetic field which sets up eddy currents in the coins of a strength dependent upon their metallic composition, and thereby causes those of different compositions to be subjected to different retardations and thus follow different projectories into separate boxes, and consists in means for (1) ensuring that all the coins enter the magnetic field at the same velocity, and (2) enabling the coin-feeding apparatus to be readily inspected and cleaned. In the form shown, the coins are delivered by a hopper A, B' through a vertically adjustable guard-ring D' on to a guide B<2> along which they are moved one at a time by fingers C<2> on a feedwheel C rotated by an electromotor. On reaching a sufficiently steep part of the guide B<2>, the coins fall into a pocket B<4> with an inclined bottom, and thence along a shoot H, between the poles of an electro-magnet F, and into the divided shoot I<1>. The fingers C<2> are carried by springs C<3> so as to yield radially if a coin sticks. Cleaning is facilitated by the open bottom K<3> and the removable side K and sections K<1>, K<2>.

Abstract: 807,268. Feeding webs. HALLEY & SONS Ltd., J., and HALLEY, A. M. April 20, 1956 [April 29, 1955], No. 12382/55. Class 100(1) A web tension controlling device, of the kind incorporating a vertically displaceable tensioning roller supported upon a loop portion of the web passing between two idle rollers, is provided with a contact arm disposed between a pair of traversably mounted micro-valves in a hydraulic or pneumatic circuit adapted to increase and decrease the rate of feed of the web, the contact arm being coupled to the tensioning roll 30 as to be displaced in a direction dependent on the direction of the vertical displacement of the tensioning roll, to thereby operate one or other of the microvalves. As shown, a web 1 is ted by feed rollers 3, 4 from a supply roll 2, the feed roller 4 being driven by a variable speed gear 5. A tensioning roller 8, carried by an endless chain 9, engages a loop in the web formed between idle rollers 6 and 7. The chain 9 pases around sprockets 10 and 11 and carries a counter weight 12. Rise and fall of the roller 8, due to variations in web tension, causes rotation of the sprockets 10, 11 and sprockets 13, 14. The sprocket 14 drives a pinion 15 engaging a rack 16 slidable in brackets 17, such that an arm 16a on the rack 16 engages a valve 18a or 18b both slidable along a guide 20. The valves 18a, 18b are connected by flexible pipes 21 to a double-acting cylinder 22. A piston rod 22a slidable in the cylinder 22, actuates an arm 5b of the variable speed gear 5 to increase or decrease the speed of the rollers 3, 4 in accordance with the upward or downward movement of the roller 8. In a modification, Fig. 2, not shown, the valves are actuated by an arm carried by an endless chain driven as a result of movement of the roller 8. Specification 744,032 is referred to.

Abstract: 768,819. Fluid-pressure servomotor control systems. STEPHEN & SONS, Ltd., A. April 29, 1955, No. 12444/55. Class 135. In a feed water control system of the kind in which, when the water in the steam drum rises above a predetermined high level, it flows into a chamber and raises a float therein to open a pilot valve to allow fluid from the steam drum to flow to a piston-and-cylinder power device 9 which latter closes the feed water valve against its spring loading, the feed water valve comprises a rotatable plug valve 2. The longitudinal movement of the piston is translated into a rotary movement of the valve through a pivoted toothed sector 24 connected to the piston and a circular rack 11 carried by the stem of the valve. The rack is formed with a handle 23 to allow of manual actuation of the valve 2. Springs 12, which load the piston of the power device, also constitute the spring loading of the valve. A vent 19 allows fluid to escape from the cylinder of the power device and thus gives warning when fluid is being supplied to the cylinder. Specifications 685,400 and 736,363 are referred to.

[Class 83 (iv)] In a machine for flanging &c. tin lids &c., the lid is clamped between two rotary discs by the eccentric adjustment of one of them. The lid is fed between a disc 5 on a shaft 11 rotated from a pulley 22, and a disc 4 on a shaft 17 rotated from the pulley 22 and mounted on an arm 12 oscillated from the cam-shaft 33. Flanging &c. discs 8, 9 are mounted on a lever 37 oscillated by a cam on the shaft 33. The initial movement of the lever 37 moves the arm 12 to effect clamping, further movement compresses a spring 42 to advance the flanging discs to operative position. In operation, lid blanks are fed singly by the co-ordinated operation of a stop 68, inlet finger 58 and interruption block 62 from the shaft 33. A cam moves the shaft 11 axially to position the grooves on the disc 5 relatively to the flanging discs 8, 9. The arm 12 is then rotated to clamp the lid and to bring the tools into contact with the lid. A stripper 55 is fitted.

The latter is rotationally mounted on a cylindrical tubular spigot 16 rigid with a frame member 2. By lifting the roller so that diametrically - opposed semi - circular recesses formed in the end periphery of the member 14, lift clear of a cylindrical pin 17 rigid with the spigot 16, the roller can be turned through 180 degrees about the axis of the spigot 16. The rollers 5 can thus occupy either of the positions shown, to provide, as desired, a troughed or flat belt support. A piece of wire 19 prevents the complete removal of the member 14 from the spigot 16. The co-acting surfaces of the member 14 and spigot 16 may be coated with nylon.
