Title: Improvements in or relating to surface grinders
IPC: B24B37/04
Filed: 1955-08-17
Abstract: 790,144. Grinding. KONG, C. Aug. 17, 1955 [Aug. 18, 1954], No. 23717/55. Class 60. In a surface grinder having a cyclically moving worktable and a grinding wheel fed towards the workpiece during grinding, the feed of the wheel is controlled by a feeler operated during each cycle of the worktable by a control member carried by the worktable, the arrangement being such that when the grinding wheel reaches the position corresponding to the desired finished dimension of the workpiece it has moved the the control member to a position such that it does not operate the feeler, so that the feed stops. The workpieces 2 are held electromagnetically on a grinding table 1 rotating under a grinding wheel 3. A control block 6 is frictionally held in a casing 7 on the periphery of the table 1 and carries an insert 6a of wear-resistant material for co-operating with the tip 11 of a feeler 4 adjustably mounted on a stationary part of the machine. Feed of the grinding wheel is controlled by contacts 9, 10 the contact 9 being secured by bar 14 to the feeler tip 11. Initially, the feeler 4 is adjusted so that the tip 11 is located in a plane containing the upper surface of the finished workpieces 2 on the table 1. The control block 6 is then set so that the upper surface of the insert 6a is above this plane. Thus at each rotation of the table 1 the insert 6a operates the feeler 4 to effect feed of the grinding wheel ; eventually, the grinding wheel depresses the control block 6 to a position such that the feeler is not operated and feed stops. A motor or time switch can be used to render the machine inoperative and return it to its starting position. The control block 6 is returned to its initial position as determined by a nut 8.

Title: Improvements in or relating to the production of deuteriumenriched compounds
Inventor: WALKER PETER THOMAS
IPC: C01B4/00
Filed: 1956-08-02
Abstract: <PICT:0864768/III/1> In the production of deuterium-enriched hydrogen or ammonia by contacting hydrogen with a counter-current of liquid ammonia containing a homogeneous catalyst in a dual temperature isotopic exchange process, the deuterium-depleted H2 leaving the cold tower is regenerated by contacting with steam of natural deuterium content in the presence of a catalyst.  As shown liquid NH3 containing potassamide and a counter-current of H2 are passed continuously in series through cold and hot towers working at 50 atms. and-60 DEG C. and 30 DEG C., respectively.  Heat is added at X and withdrawn at O in the circuits possibly by interlinking. Enriched hydrogen is withdrawn at B and passed to distillation at-225 DEG C., whence a highly-enriched fraction is recovered and combined with O2 to form heavy water, and a depleted fraction is passed into the H2 cycle.  The H2 is regenerated by contact with steam at 550 DEG C. before return to the hot tower.  Alternatively, enriched NH3 may be withdrawn at A and distilled to isolate an enriched fraction.

Abstract: 241,009. Leyde, J. Oct. 14, 1924. Colouring.-Kinematograph films bearing colour-record images in sequence are coloured, on the sides not coated with emulsion, by means of colouring matter dissolved in a celluloid solvent which also contains celluloid in solution; dissolved celluloid may be added to the solution to regulate its viscosity. The solvent may consist of a mixture of acetone and amyl acetate. The colouring may be effected by means of rollers 4 having raised sections each equal in size to an image, the rollers being arranged so that their surfaces do not contact with the film but come only so near to it that the colouring solution touches and adheres to the surface. Counter rollers 6 may be adjusted to regulate the distance between the film and the rollers 4. As shown, two rollers 4 dipping into troughs 5 containing the colouring solution are provided, each roller being constructed and arranged to colour alternate image spaces, and the film being led from the spool 1 to the spool 8 by means of sprockets 2, 3 and drying rollers 7.

[Also in Division G3] In a gyromagnetic resonance spectrometer having a closed yoke magnet system enclosed in a temperature controlled oven and an air-driven turbine for sample spinning, means are provided for measuring the rate of rotation of the sample. Light from a source is reflected from the spinning sample container, the reflected light being modulated at a frequency proportional to the rate of rotation of the container. A photo-detector generates a corresponding electrical signal which is then amplified and fed to a Schmitt trigger circuit, the output of which is differentiated and fed to a monostable multi-vibrator whereby the D.C. average of the output of the monostable multivibrator is a measure of the rate of rotation of the sample. This output signal may be compared with a reference signal representing a desired rate of rotation and any error signal used to control the spinner air supply. By scanning a sample spectrum using two different spinning rates; spinning sidebands may be readily distinguished from main peaks.
