Abstract: 992,710. Valves. TRICO-FOLBERTH Ltd. Dec. 10, 1962 [Dec. 8, 1961], No. 44069/61. Heading F2V. Two separate rubber tubes 6, 8, Fig. 1, are pinched against body plates 10, 12 by balls 2, 4 upon axial displacement of a cam 14 upon depression of a spring-loaded rod 16. The latter embodies a head 24 with lugs 26, 28, Fig. 4, that slide in body grooves, which grooves also accommodate lugs 20, 22 on the cam 14. The head 24 is provided with teeth 36 which upon depression of the rod 16 abut the lugs 20, 22 and cause axial movement of the cam 14 followed by rotation thereof when the lugs 20, 22 clear the body grooves; this rotation is continued when the lugs 20, 22 engage further teeth in the body. The valves are opened by retracting the cam 14 when the rod 16 is again depressed. Specification 961,598 is referred to.

Abstract: 1,076,396. Measuring linear dimensions electrically. ALLMANNA SVENSKA ELEKTRISKA A. B. Nov. 9, 1964 [Nov. 14, 1963], No. 45564/64. Heading G1N. The radius of a grinding wheel subject to reduction due to wear in use is measured as a function of the capacitance between two systems of electrodes positioned on the same side of the disc which capacitance is determined by the size of the locally associated earthed side face of the disc. If the disc itself is not sufficiently conductive, the earthed side face may have a coating of conductive paint. As shown in Fig. 1, electrodes 4 to 9 are connected to different tappings of a transformer secondary winding 3 and are partly shielded from an electrode 10 by an earthed screen 15. The voltages applied to the different electrodes 4 to 9 may be selected so that the output at terminals 19 is inversely proportional to the radius for use as a control signal for keeping the peripheral speed of the wheel constant or inversely proportional to the square root of the radius for use as a control signal to keep the centrifugal force at the perimeter constant. The role of electrodes 4 to 9 and 10 may be exchanged. In Fig. 4 (not shown), the electrodes are discs located in staggered holes in a steel plate and protected from sparks by a coating of mica flakes bound in glass.

Title: Improvements relating to the production of peracetic acid
Inventor: SHARMAN DONALD ARTHUR
IPC: C07C409/26
Filed: 1963-12-03
Abstract: Peracetic acid is prepared by reacting an excess of acetaldehyde and oxygen in the vapour phase to produce a reaction mixture containing peracetic acid, acetic acid and unreacted acetaldehyde, passing the mixture so produced to a distillation column to which a solvent for the peracetic acid is fed whereby a solution of peracetic acid and acetic acid in the solvent is formed and removed from the base of the column and a gaseous stream containing acetaldehyde and solvent passes from the top of the column to a partial condenser which serves to return part of the acetaldehyde and solvent as reflux to the distillation column, and recovering acetaldehyde from the uncondensed gaseous stream leaving said partial condenser while the gases are compressed for at least part of the recovery process.  Said compression may be effected by feeding the gases leaving the partial condenser into a liquid seal rotary compressor to which the solvent to be used in the peracetic acid extraction is fed so as to form the liquid seal, the gas stream from the compressor being condensed and the solution of acetaldehyde in the solvent so produced being passed to the distillation column to provide at least part of the solvent feed to the column.  A portion of the acetaldehyde-solvent reflux stream may be fed to the liquid seal rotary compressor to make up the liquid seal requirements. Acetaldehyde vapour leaving the condenser after the compressor may be scrubbed with water and distilled prior to re-use as required.  Specification 1,099,263 is referred to.
