Title: Stabilised phenyl-hydrazine and process for making it
Filed: 1953-10-29
Abstract: Phenylhydrazine is stabilized by the addition of hexamethylene tetramine after manufacture or during purification by distillation. The hexamethylene tetramine is added, preferably in a proportion of 1 to 3 per cent, and as a warm saturated solution in phenylhydrazine. The degree of purity of phenylhydrazine is measured by its solidification point and the solidification points of two samples are compared.  Both samples contain zinc which catalytically accelerates the decomposition, and one sample contains 2 per cent of hexamethylene tetramine.  After 7 months the unstabilized material contains 89.5 per cent phenylhydrazine and the stabilized material contains 98.5 per cent phenylhydrazine calculated on the original phenylhydrazine content.

IPC: B44C1/22
Filed: 1927-11-10
Abstract: 302,027. Spargo, E. E. Nov. 10, 1927. Ornamenting.-Graining effects are produced on wood by first forming grooves or indentations under pressure in the surface of the wood by means of dies provided with corrugations, serrations, ridges, &c., the grooves &c. extending transversely of the natural grain of the wood, and then planing or otherwise smoothing the surface down to the bottoms of the grooves formed by the dies, the markings being formed by the permanent effect of the compression of the wood. The effects may be made more distinct by a preliminary treatment of the wood with a solution of carbonate of soda or with an aniline dye, and the surface may be finally varnished, stained, or french polished. Apparatus for forming the corrugations &c. may consist of dies formed on the bed and p1aten of a screw press, or on a roller cooperating with a flat or curved bed or die, or on a roller which is rolled over the surface of the wood. Fig. 1 shows apparatus comprising a pair of grooved rollers 6 supported in a framework 7. The upper roller 6 is mounted in vertically slidab1e bearings 12, and is pressed down on to the work by springs or by a weight 19 on the end of a hand-lever 18, which is pivoted at 17, and is integral with arms 16 adapted to be attached in various positions according to the thickness of the work to rods 14 connected to the bearings 12. Gas-pipes 26 are provided for heating the rollers 6. Fig. 3 shows the rollers 6 modified to deal with wood of various sections, e.g. angle, quarter round, half round, and round.

[Also in Division H2] An electric motor which drives a reversing rolling mill is controlled in accordance with the roll spindle torque to provide a desired programmed relationship between the armature current of the motor and the rolling time whereby the mill is operated with optimum efficiency. A motor-speed signal n is amplified and supplied to section 2 of an electronic computer 1, a signal representing the first derivative of the speed being supplied to section 3. This section also receives a current-signal and supplies a torque-signal to section 4 which also receives a signal from section 2 indicating the remaining length of material to be rolled at a given instant. A signal corresponding to the kinetic energy of the rolls is supplied from section 2 to section 5, and one indicating the remaining work to be performed by the mill is supplied by section 4. In this manner, a reference signal for the armature current is formed which is compared with the actual current in regulator 7 for controlling the motor. The speed-signal is supplied to the computer only when the material is between the rolls, a relay responding when an ingot enters the gap. When the motor is operated with reduced excitation, a compensating signal representing the flux is supplied to section 3.
