Title: Improvements in or relating to the production of acid derivatives of ortho-naphthoquinone-diazide-carboxylic acids, particularly aromatic esters and aromatic amides
IPC: G03F7/022
Filed: 1956-02-22
Abstract: The invention comprises (a) a process of preparing o - naphthoquinone - diazide - carboxylic acid chlorides by heating the acids with excess thionyl chloride, and also (b) a process of reacting these acid chlorides with aromatic hydroxy compounds or aromatic amines with or without acid-binding agents to produce the esters or amides. The naphthoquinone-(1.2)-diazide-(1)-carboxylic acids may be made by coupling a 2-hydroxynaphthoic acid with a diazo compound to give an azo compound, reducing this to give an amino-hydroxy-naphthoic acid and diazotizing.  The naphthoquinone-(1.2)-diazide (2)-carboxylic acids may be made by nitrosating a 1-hydroxy naphthoic acid, reducing the 2-nitroso compound so obtained to the amino-hydroxy-naphthoic acid and diazotizing.  The esters and amides are suitable for the production of light-sensitive layers on metallic carriers.  In examples, (1) naphthoquinone-(1.2)-diazide-(1)-carboxylic acid (3) is converted to its chloride with thionyl chloride, and the chloride is reacted with phenol, 71-hydroxy-N-(n-propyl)-C-(2)-ethyl naphtho - 11.21.4.5 - imidazole, b -naphthol, p - nitrophenol, 4.41 - dihydroxydiphenyl, or N - benzylaniline; (2) naphthoquinone-(1.2)-diazide-(1)-carboxylic acid (6) (which is prepared by coupling diazotized aniline with 2-hydroxy-6-naphthoic acid, reducing the azo body, and diazotizing) is converted to its chloride and this is reacted with phenol or diphenylamine; (3) naphthoquinone - (1.2) - diazide - (2) - carboxylic acid-(5) (prepared by nitrosation of 1-hydroxy-5-naphthoic acid, reduction of the 2-nitroso compound, and diazotization) is converted to its chloride and this is reacted with phenol or with 1 - amino - 2 - ethoxy - naphthalene; (4) naphthoquinone - (1.2) - diazide - (2) - carboxylic acid-(3) is converted to its acid chloride, and this is reacted with b -naphthol; (5) naphthoquinone-(1.2) - diazide - (2) - carboxylic acid-(4) (prepared from 1-hydroxy-4-naphthoic methyl ester by nitrosation, saponification, reduction, and diazotization) is converted to its acid chloride and reacted with b -naphthol; (6) naphthoquinone-(1.2) - diazide - (1) - carboxylic acid-(4) is converted to its acid chloride and this is reacted with diphenylamine.

Title: Extrusion apparatus for, and method of producing film, sheet or tubing of extrudablematerial
IPC: B29C48/09
Filed: 1956-02-24
Abstract: <PICT:0822812/IV (a)/1> In producing tubular films by melt extruding a synthetic organic high polymer through an annular die a stream of the material which is in a plastic and non-aerated state is passed on its way to the die through a foraminous screen moved transversely of the stream. As shown in Fig. 2, the plastic material is fed into the extruder head 2 through the spider openings 10 into the outer annular chamber 20 and from the chamber 20 through the openings 22 of the rotating cylindrical screen 19 into the inner annular chamber 21 concentric with the outer annular chamber 20.  From the chamber 21 the material flows in unobstructed passage in a direction generally parallel to the axis of the screen, into the die 16 and is extruded through the annular die orifice 18 to form a tubular film 35, which is inflated in the usual manner by admitting compressed air to the interior 36 of the core 8 through the inlet 37 so that air passes into the interior of the tubular film 35 through the duct 38 in the die 16.  The cylindrical screen 19 is rotated about its axis by means of a variable speed motor the bevel pinion 33 on the shaft 29 of which engages a bevel gear 23 fixedly mounted around the periphery of the screen 19.  The screen 19 is rotatably mounted in the extruder head 2 by means of the combined radial and axial thrust roller bearing 27.  The invention eliminates the formation of die and closure lines on the extruded tubular film.  The rotating cylindrical screen or filter may be composed of a porous ceramic or sintered metal powder and may be rotated continuously in one direction or first in one direction and then in another, or may be reciprocated in a direction transverse to the direction of flow of the plastic material through the extruder head.

Abstract: 713,804. Impedance networks. BRITISH INSULATED CALLENDERS CABLES, Ltd. March 10, 1953 [March 10, 1953], No. 6196/52. Class 40 (8) An arrangement for maintaining a desired relation between the resistive and reactive components of the impedance of a variable resistor comprises a two terminal impedance network comprising a line leading from the two terminals 32 to a fixed non-inductive resistor R with a variable inductive resistor r inserted in one side of the line and with variable capacitors C1, C2 across the line on each side of the variable resistor, the adjustments of the variable elements being coupled for simultaneous and related movements. In particular when it is desired to obtain a pure resistance the maximum values of both the resistive and reactive components of the variable resistor r are made much smaller than the value of the fixed resistor R and the arrangement is so designed that R = #L/C 1 +C 2  throughout the range of adjustment, L being the inductance of the variable resistor, the capacitances C1, C2 being made equal or nearly equal. The variable resistance r takes the form of a fine metal strip 1 connected at one end to the inside of an elongated metal box 3 and at the other to a terminal 7 passing through an insulating plate 5 forming one end of the box. Spring contacts 11 for the strip are carried by a slide 9 which is recessed for the accommodation of a nut 17 threaded upon an adjusting spindle 15. Rotation of the nut 17 is prevented by a pin 18. Spring loaded ball bearings 13 press the slide 9 into contact with the box 3. The slide 9 also carries, by means of an insulating block 22, the common moving plate 24 of the two capacitors C1, C2, the fixed plates 26 and 27 being connected respectively to the metal box 3 and to an insulating block 19. The moving plate 24 is connected by a lead 28 to the metal base plate 21 whilst the insulated fixed plate 27 is connected by means of a bus bar 33 and a short coil 35 to the terminal 7. The moving plate 24 may be adjusted towards and away from the fixed plates. The input terminals are provided by a co-axial stub 32 whose outer conductor is connected to the metal base 21 and whose inner conductor is connected to the box 3. The fixed resistor R is connected between the bus bar 33 and the base plate 21. Trimmer capacitors 29, 30 are connected between the base plate 21 and the bus bar 33 and the box 3 respectively.

Title: Improvements in and relating to program controllers
IPC: G05B19/12
Filed: 1958-02-26
Abstract: 878,218. Electric programming. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Feb. 26, 1958, No. 6286/58. Class 38 (6). The invention relates to apparatus for causing a probe to follow a conductive line drawn on a chart, the probe being mechanically linked to a variable resistance, inductance or capacitance whose value therefore indicates the distance of the line at the location of the probe from a zero axis. As shown, Fig. 1, the pen of a recording meter 10 is replaced by a pair of probes 1 which follow a conductive line 2 on a moving chart 3, representing a recorded programme, by causing the line 2 to close the charging circuit for a capacitor 4, the voltage across the capacitor being measured by the motor 10 and displacing the probes 1, whereby the capacitor 4 now discharges through a resistor 7, the voltage measured by meter 10 falls, and the probes 1 are moved back on to the line 2, and the cycle restarts. Thus the probes 1 hunt about the conductive line 2, an adjustable bias voltage Vb determining the zero position of the probes on the chart. In a modification a cathode follower valve is introduced between the capacitor and the meter. In a further modification one probe is replaced by a metal plate located beneath the chart, the plate and the conductive line forming a capacitance which operates a proximity switch controlling the charging circuit when the probe is in contact with the line. The arrangement may be used to control the temperature of a furnace 34, Fig. 4, wherein a thermocouple 35 feeds the recording meter 36, and relative movement between the probes 37 and the programme curve 38 controls the heating supply in on-off manner via the charging arrangement described above.
