[Also in Division F4] A valve for controlling the discharge of condensate from a compressed air reservoir comprises a body 1 having a drain chamber 4, in constant communication with reservoir, and a discharge chamber 7, having an inlet 8 and an outlet 10. An inlet valve 9 loaded by a spring to the closed position has a stem 9a and an outlet valve 12, also loaded by a spring, has a stem 12a. A valve actuating mechanism 14 comprises a tube member 18 which receives a threaded cup member 19 having an apertured partition wall 19a. The tube member is surrounded by a sleeve 20 slidable in a portion 13 of the housing and the sleeve 20 and members 18, 19 clamp these members to diaphragms 15 and 16. The pressure in chamber 7 acts equally on the outer sides of the diaphragms and the upper diaphragm is subjected to an intermittent pressure supplied through a pipe 24 to reciprocate the actuating means whereby the valve 10 is closed prior to the opening of valve 9 to allow the condensate to flow into discharge chamber 7 and the valve 9 closes prior to the opening of valve 10 to discharge the condensate to atmosphere. The pressure to pipe 24 may be controlled by applying the brakes or by a governor valve of a compressor when the reservoir is in a braking system.

Title: Method of producing vanillin and other useful products from lignosulfonic acid compounds
Inventor: CRAIG DAVID
IPC: C07C51/23
Filed: 1961-02-14
Abstract: Alkaline oxidation of lignosulphonic acid compounds is effected by a process in which a gas containing free oxygen is passed in finely dispersed form through a reaction zone containing lignosulphonic acid compounds and lime and to which mixture sodium carbonate had been added.  The following reaction conditions are maintained: -(1) temperature 120-200 DEG C., (2) partial pressure of oxygen below 20 p.s.i., (3) time less than 4 hours and (4) the amount of sodium carbonate is equivalent to the calcium content of the lignosulphonic acid compounds plus an amount which on reacting with the lime maintains a pH not less than 12.  The reaction products are separated into a solid phase (essentially calcium carbonate) and a liquid phase containing sodium derivatives of vanillin, acetovanillone, lignin substance and oxalic acid.  Optional subsequent steps to isolate the oxidation products include solvent extraction, de-emulsification with a surface active agent and acidification to precipitate lignin substance.

[Class 83 (iii).] Nut blanks are carried by chucks arranged in rows in a table, the latter being fed forward after each operation to present a fresh row to the axially movable and rotatable taps. A cylinder M, with holes P for the passage of waste, carries rows of nut-holding chucks N, Fig. 5, and is intermittently rotated to present each row in turn to a corresponding row of taps by a rotating disc F carrying a pin H engaging radial slots in a disc K on the axle of the cylinder, the latter being located by a cam-operated spring-pressed dowel S engaging holes in the disc K. The curved-shank taps are carried in spindles m driven from a shaft B through bevel gearing f, g and spur gearing j, k. A bevel wheel d on the shaft B drives, through gearing, fast and slow wheels W and X respectively either of which may be automatically clutched to a shaft C in order to give the machine increased speed during the rotation of the cylinder. The taps are raised by a bar p, cam-operated from the shaft C, engaging collars on the spindles. Safety-levers 9, Fig. 5, slotted for the passage of the taps swing aside as the spindles are raised and prevent the lowering of the tap if a nut is still retained on the threaded portion.

Abstract: 397,548. Supply holders for yarnwinding and like machines. TENNANT, W. J., 111, Hatton Garden, London.- (Universal Winding Co. ; 95, South Street, Boston, U.S.A.) Feb. 26, 1932, No. 5779. [Class 120 (ii).] In yarn or like winding machines the support for the supply package is arranged so that the package extends downwardly and the yarn therefrom passes downwardly to a guide and thence upwardly to the winding-spindle, so that the supply package may be located adjacent to the package being wound while maintaining the necessary length of free yarn between the packages. The holder for the supply package is provided with a retaining device for the bobbin to enable it to be operative when downwardly directed. As applied to a machine such as described in Specification 339,679, [Class 120 (ii), Spinning, twisting, &c.], wherein a grooved roll 7 serves to traverse the yarn and frictionally drive the winding-cone C which is freely mounted on a dead spindle 10 and held thereon by a latch, a supply holder is carried on an arm 51 adjustably secured to a bracket 21 and the yarn y passes through a guide 48 and a slub-catcher 47, between tension discs 34, and around a guide 33 up to the cone C. The supply holder is provided with oppositely arranged stub spindles 60, 61 on a hub 62, and a retaining-device in the form of arcuate strips 75 is provided to engage the head or flange b<1> of the supply bobbin during the rotation of the holder to bring a new bobbin into position for unwinding and during the unwinding period, but during such rotation the empty bobbin is released and drops into a suitable receptacle. Spring-controlled snap-plungers 68 maintain the holder in position. Modifications of the holder are described for engaging the interior of supply bobbins which are not provided with flanges such as b, latches 87, Fig. 8, and dogs 110 and spring-pressed plungers 103, Fig. 11, being operated during rotation of the holder by suitable surfaces and notches in the axle to grip and release the bobbins as necessary. In the arrangement shown in Fig. 8, snapplungers 73 serve to maintain the holder in position, but in that shown in Fig. 11 the plungers 103 serve for this purpose as well as for controlling the dogs 110. Specification 378,964 also is referred to.

Title: Process for sterilising beer
IPC: C12H1/18
Filed: 1932-02-26
Abstract: Beer artificially enriched with carbon dioxide is sterilized by heating, e.g. at 70-100 DEG  C., under a pressure, e.g. 10-15 atmospheres, which exceeds the saturation pressure of the carbon dioxide at the temperature employed, the beer being passed during the treatment over a bactericidal metallic surface.  The enrichment of the beer may be effected by injecting carbon dioxide into the preheated or hot beer during the sterilizing process. The pressure of the sterilized beer may be gradually reduced so that it leaves the sterilizing apparatus under normal pressure.

Abstract: A resinous composition comprises a base-stable high molecular weight polyoxymethylene having dispersed therein 0.01 to 5% of a compound <FORM:1044863/C3/1> where R is hydrogen, an alkyl group of 1 to 20 carbon atoms, an alicyclic group of 3 to 8 carbon atoms, an aryl group of 6 to 10 carbon atoms, an aralkyl group of 7 to 30 carbon atoms, or a carboxyalkyl group of 2 to 10 carbon atoms and R1, R2 and R3 are one of the foregoing groups or amino groups.  In the examples pyrazole, 3,5-dimethylpyrazole, 3-aminopyrazole, 3-amino-4-carbethoxypyrazole, 1-phenylpyrazole, 3-methylpyrazole and 3,5-dimethyl-1-phenylpyrazole are the stabilizers used. Others are specified.  The pyrazoles are incorporated by dry blending followed by melt processing, a thermal stabilizer, e.g. a polyamide and an antioxidant, e.g. 2,21-methylene-bis - (4 - methyl - 6 - tert. - butylphenol) also being added.  The polyoxymethylene may be prepared by polymerizing formaldehyde and thereafter converting the polymer to a base-stable polyoxymethylene ether.  Alternatively, a base-stable copolymer composed of oxymethylene units interspersed with substituted alkylene or oxyalkylene units is employed.  In both cases unreacted polyoxymethylene is removed by dissolving the product in a solvent and heating it, optionally in the presence of a strong amine or caustic, to depolymerize the unreacted polyoxymethylene, or alternatively by heating the solid or molten polymer.
