Title: Phenothiazine derivatives, and their preparation
Filed: 1959-09-08
Abstract: The invention comprises compounds of the general formula <FORM:0905692/IV (b)/1> (wherein X represents a hydrogen or halogen atom or a low molecular (i.e. C1-4) alkyl or alkoxy group, R1 and R2 represent low molecular alkyl radicals which can be bound to each other directly or through an oxygen atom or the nitrogen atom of a low molecular alkylimino, alkanoyloxyalkylimino or hydroxyalkylimino group, and n is a number from 1 to 3) and the preparation thereof by reacting a compound of the general formula <FORM:0905692/IV (b)/2> with a reactive ester of an aminoalcohol of the general formula <FORM:0905692/IV (b)/3> or by reacting a compound of the general formula <FORM:0905692/IV (b)/4> (wherein Y represents a reactive esterified hydroxy group) with a secondary amine HNR1R2 or by treating a compound of the general formula <FORM:0905692/IV (b)/5> with a low molecular alkylating agent.  The products and their acid addition salts have antiallergic and sedative activity, whilst quaternary ammonium salts derived therefrom (e.g. by the action of aliphatic or araliphatic halides or sulphates) have a ganglioplegic action.  The bases can also be made by reacting a compound of the second general formula above with phosgene, reacting the resulting 5-chlorocarbonyl compound with an amino-alcohol of the third general formula above, and heating the resulting ester of the general formula <FORM:0905692/IV (b)/6> until carbon dioxide is split off.  Reactive esters of the fourth general formula above are prepared by reacting compounds of the second general formula above with haloethoxyethanols or a haloethoxyethoxyethanols and esterifying the resulting hydroxy compounds with strong inorganic or organic acids, e.g. halogen hydracids (by the action of inorganic acid halides), sulphuric acid or organic sulphonic acids.

Abstract: 1,029,855. Semi-conductor devices; potentiometers. BENDIX CORPORATION. Aug. 6, 1963 [Aug. 6, 1962], No. 31033/63. Headings H1K and H15. [Also in Division G1] Devices are described in which the position of a spot of light is measured by its effect on a semi-conductor device. Three of the embodiments may be regarded as potentiometers in which the effective tap position is controlled by the position of a relatively small light spot shone on to a reverse biased PN junction. One of the zones forming the junction is of relatively resistive material and has two contacts placed at opposite ends of a line parallel to the junction. A potential source is connected to these contacts to provide a gradient parallel to the junction. The other junction-forming zone has parallel to the junction a terminal surface largely covered by conductive material. The output is taken from this material and that side of the source which ensures that the junction is reverse biased. The germanium or silicon device of Fig. 1 (not shown) has non-linearities in the extremes of its output and light spot position characteristic. To reduce these the body may be enlarged near contacts 23, 24 and electrode 22 may be stopped short of the corners of the body. In the embodiment of Fig. 2 (not shown), the " output " region of the body is greatly enlarged at its electrode-covered end compared with its size at the junction. The device described with reference to Fig. 3 (not shown) is formed from a circular semi-conductor disc the centre of which is of P-type material while the annular outer portion is of N-type material. An ultrasonically cut radial slot divides the annular portion so that it is discontinuous. The two electrodes used in forming the potential gradient are applied to opposite walls of the slot and the output electrode is formed by a circular disc on the central region. The remaining embodiment (Fig. 5, not shown) is formed from a circular disc with an inner P-type region surrounded by a continuous annular N-type region. Four pairs of oppositely disposed contacts are provided on the two regions and ohm-meters connected between the contacts of each pair. Comparison of the meter readings enables the position of a small light spot bridging the junction to be determined by its effect on the resistance of the junction.
