Abstract: The invention comprises metallized azo dyes containing bound to a chromium atom, two monoazo dyes one being of formula <FORM:0986655/C4-C5/1> and the other formula <FORM:0986655/C4-C5/2> wherein X is a hydrogen or chlorine atom or a nitro group, Y is a hydrogen or chlorine atom or a nitro or methyl group and X and Y are different from each other, R and R1 are benzene residues and Z is a chlorine atom or a nitro group.  The dyes are prepared by reacting equimolar proportions of the first azo dye with the 1 : 1-chromium complex of the second azo-dye. The dyes are used to colour natural and synthetic nitrogenous fibres in red shades. Examples describe the preparation of the dyes. Specification 765,335 is referred to.

IPC: H04N5/50
Filed: 1958-12-19
Abstract: 853,932. Tuning indicating. STANDARD TELEPHONES & CABLES Ltd. Dec. 19, 1958 [Dec. 24, 1957], No. 41155/58. Class 40(5). In a television receiver a voltage for tuning indication is derived from a sharply-tuned circuit L, C, coupled to a video or sound I.F. stage which feeds a gridcontrolled rectifier RO1. The cathode of the valve RO1 is biased back by a source B of positive potential, its anode supply comprising positive-going flyback pulses which are supplied over condenser C1. The anode of the valve acquires a negative potential proportional to the amplitude of the IF signal, and this is smoothed by network Rl, 2, C2 before application to a tuning indicator (not shown).

[Also in Division G2] An optical fibre having a refractive index variation in a transverse plane in accordance with the formula n=n 0 (1-ar<SP>2</SP>), where n 0  and n are the values at the axis and at a distance r from the axis and where "a" is a positive constant, is used as an objective lens in a microscope. The fibre may be very narrow and flexible (as shown) and, with a conventional eyepiece 32, provides a microscope which allows examination over a wide surface area of an irregular shaped object, and even internal examination of narrow holes, without moving the eyes. If two such fibre lenses are used in conjunction with eyepieces, stereoscopic microscopes may be formed with either rigid objective heads (Figs. 2, 3, not shown) or flexible objective heads (Fig. 4) and in both cases the focal lengths may be as little as 30 microns. A stereoscopic microscope (Fig. 5, not shown) may also provide object illumination by including a fibre optic light guide (19) and source (17) as well as fibre "lenses" (18, 18a), and due to the small cross-sections of the fibres an objective probe may be made small enough (Fig. 8, not shown) to fit inside an injection needle which is to be inserted into the human body.

Title: Digital data transmission system
IPC: H04L25/02
Filed: 1962-10-31
Abstract: 1,008,255. Transistor switching circuits; pulse code modulation circuits. SPERRY RAND CORPORATION. Oct. 31, 1962 [Nov. 13, 1961], No. 41232/62. Headings H3T and H4L. In a data transmission system in which a driver stage feeds an amplifier via a, for example, twisted pair transmission line, the driver has means for providing low impedance charging and discharging paths for the line capacitance so that substantially equal charging and discharging rates are obtained and the amplifier includes means for balancing out noise appearing on the line. One driver may be connected to a number of amplifiers, or a number of drivers to one amplifier. Output driver, Fig. 4, comprises a number of inputs 54 connected in an OR circuit to the base of a first transistor 68. With a logical " 0 " at all inputs transistors 68, 118 are non- conducting and the output line 140 is clamped by diode 144 to - 3 V. With a logical " 1 " input, the states of the transistors are reversed resulting in the line being at earth potential. In order to provide a discharge path for the line when transistor 118 is non-conducting, the output from transistor 88 is also fed via a capacitor 128 to transistor 110 to render it conductive when transistor 118 is cut-off. During this time capacitor 128 charges to control the impedance of transistor 110. In a modification, Fig. 6 (not shown), the driver is arranged to present a high impedance to the line in the absence of operating power, by replacing resistor 134 with a diode, removing clamping diode 144 and connecting a Zener diode across the output lines. Amplifier, Fig. 5, comprises a pair of transistors 154, 162 connected as a long tailed pair to balance out the noise on the line. With - 3 V. on the line 178 transistor 154 is on and transistor 162 is cut-off to switch transistor 170 on so that the output terminal 236 is at earth. With the input on line 178 at earth, the converse conditions obtain. The output transistor 170 may be gated off if desired by a gate signal on terminal 226.

Abstract: 1,115,847. Transferring samples. CESKOSLOVENSKA AKADEMIE VED. 30 Sept., 1965 [1 Oct., 1964], No. 41576/65. Heading B1X. [Also in Division F1] A device for transferring a fluid into a sample receptacle in an automatic analytical process for example column chromatography comprises a pump having a cylinder 3 and a piston 5, a valve 6 arranged to effect communication between the pump cylinder and either a sample receptacle or a discharge outlet, and a cam means 23 for effecting displacement of the piston and provided with a number of preset stops. The stops are formed on a disc 25 secured to a shaft 24 on which the cam 23 is mounted, the shaft being rotatable by a hand operated knob or by a servomotor. In operation, the end of a tube connected to an inlet 9 on the pump is lowered into a sample receptacle and the shaft rotated thereby causing the piston to move under the action of a spring 12 and so suck in a sample until a roller 26 on a spring-loaded lever 27 drops into a notch formed on the disc 25. The tube can then be removed and lowered into a further receptacle and the cam rotated to cause a further sample to be drawn into the tube. To dispense the sample the valve 6 is moved to connect the pump with an outlet 8 and a lever 20 connected to the piston is then moved against the action of the spring 12 thereby forcing the liquid from the tube.

As shown annular metal cup members 12 are positioned between the discs 8 and contain the water absorbing material; the cups may be internally painted with an electro-chemical conductive paint. When used as an earth electrode the shank is driven into the ground and then the nut 16 is tightened to radially expand discs 8 and cause them to make good contact with the ground. The material in the cups absorbs moisture and provides good electrical contact between the shank and the ground. The device may be used as a lightning conductor and be connected to a similar device embedded in the ground.

Title: Improvements in or relating to processes of manufacturing semi-conductor devices

Filed: 1959-12-08
Abstract: 878,544. Semi-conductor devices. VALDMAN, H., and GICQUEL, R. Dec. 8, 1959 [Dec. 9, 1958], No. 41729/59. Class 37. Electrodes are soldered to a semi-conductor element by means of a eutectic gold lead alloy to which is added a substance which increases its malleability. Figs. 2a, 2b show the attachment of a gold electrode 41 to a silicon wafer 1 carrying a nickel coating 21 by means of a solder of the type described. Since the gold is soluble in the solder the end of wire 51 is enlarged but the main advantage occurs when the device is subjected to an etching bath of nitric acid of density 1.38, hydrofluoric acid at 40% and glacial acetic acid in the proportions 2: 1 : 1. The chemical attack takes place over the entire exposed area of the semi-conductor but relative electro-chemical erosion reducing the contact area takes place near the contacts as shown in Fig. 2a. When a number of contacts are made on a single plate the elements may be separated from each other by the etching process (Figs. 3c, 3b, not shown). The substance increasing the malleability of the solder may be 5% tin, 3% indium or 3% gallium. The process may be applied directly to germanium but if indium or gallium are used the surface must be nickel coated to avoid rectifying action of the contacts. When the semi-conductor is germanium or when electrodes having an expansion coefficient near that of silicon are used with silicon the arrangement shown in Fig. 4 may be used. The silicon plate 1 nickelled on both faces is held by graphite discs in which are cylindrical holes carrying electrodes 51, 52 of gilded " Dilver P " which are soldered in a furnace by means of pellets 41, 42 of the solder described. Specifications 832,067 and 816,799 are referred to.
