Title: Photo-responsive units
Inventor: GOODWIN DAVID
IPC: G01N21/88
Filed: 1960-02-23
Abstract: 970,707. Photo-electric units. BRUCE PEEBLES & CO. Ltd. Feb. 9, 1961 [Feb. 23, 1960], No. 6372/60. Heading G1A. In a protective system for a photo-responsive unit including a source of H.T. potential, with associated capacitance elements, for the unit, and an electronic switch operative to reduce or remove the potential in response to an increase in the output from the unit beyond a predetermined level, a timing circuit controlling the switch does not include any "lumped" capacitance or inductance, affecting its time constant, and the charge on the capacitance in the potential source is not changed substantially by the switching operation. The electronic switch may comprise a valve or transistor or an electrical impedance whose impedance value can be varied electrically. The "lumped" capacitance or inductance refers to these electrical variables due to components specifically included because of their capacitance and inductance. The arrangement is described in connection with apparatus for detecting pinholes in a sheet 1 of tin plate by a light-source 2 energized from a 4kc/s oscillator 3, in conjunction with a bank 4 of nine photomultipliers energized by a 230 volt A. C. supply 11, a transformer 12 in series with a pentode valve 16 and a diode rectifier 13 with shunt capacitors 14. The casing of the light source 2 is provided with edge masks 5, and the photo amplifier has, in addition to an operating output 6, a parallel output 17 leading to a four-stage amplifier 18 not including in its signal circuit any "lumped" capacitance or inductance. The normal value of the operating H. T. is set by a potentiometer 19, and the D. C. amplifier 18 includes a potentiometer 21 for setting the limit corresponding to the output signal from the multiplier at which the H.T. is to be cut off. Feed-back voltage from the source 3 provides some automatic compensation at the potentiometer 21 in relation to the intensity of the light-source 2. The protective system operates in respect of any large increase in the ambient light conditions, or if any of the nine photo-multipliers gives rise to an excessively large output, or if a number of the individual multipliers give rise to outputs substantially above a predetermined maximum value.

Title: Improvements in or relating to a di-substituted hexane
Filed: 1945-03-15
Abstract: The compound 3 : 4 - bis - (p - aminophenyl) hexane is prepared by heating a p-propioacylanilide in which the acyl group contains from 2 to 17 carbon atoms with hydrazine to form the corresponding azine, reducing this to p-propio-acylanilide dihydroazine and then heating to split off nitrogen to give 3 : 4-bis-(p-acylaminophenyl) hexane. The required free amino compound is finally formed by acid or alkali hydrolysis.  In an example, p-propiopropionanilide is heated with hydrazine hydrate in alcoholic acetic acid solution to form p-propiopropionanilide azine, which is reduced with hydrogen in the presence of palladium chloride to the corresponding dihydroazine. Heating in a bath at 180 DEG  C. results in the evolution of nitrogen gas to form 3 : 4-bis-(p-propionaminophenyl) hexane.  The free amino compound is formed by hydrolysis with hydrochloric acid.
