Title: Improvements in electrode systems with unsymmetrical conductivity
IPC: H01L21/108
Filed: 1937-08-10
Abstract: 486,829. Asymmetrically - conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 10, 1937, No. 22000. Convention date, Aug. 13, 1936. [Class 37] In an electrode system having two eleetrodes of different conductivity, one of which is a selenium electrode, separated by an insulating blocking layer, the blocking layer is at least partly constituted by a stable, solid, insulating chemical compound, the substance cap - able of yielding this compound by chemical conversion being present as an addition in the selenium electrode. In the example shown the selenium layer 3 is deposited on a carbon layer 2 on the aluminium support 1. The blocking layer 4 is formed on the selenium, and upon this is sprayed a conductive alloy to form layer 5. The additions to the selenium are one or more easily volatile halides which readily hydrolyze with water. A list of suitable halides is given in the Specification. The halides are added either directly to molten selenium, the mixture being afterwards distilled, or by vaporizing them in a current of gas which is then passed through the molten selenium previously distilled The selenium is then pressed on a metal support, the blocking layer being formed on the side of the selenium remote from the support by the chemical reaction, whilst being heated, of the added halide with a substance having an alkaline reaction. This substance may be an alkali such as caustic soda or potash lye or an organic substance such as pyridine or aniline in a solvent having a high boiling point such as glycerine or quinoline. Specification 468,736 is referred to.

[Class 78 (v)] In mechanically driven winches of the kind in which the drum can be orientated in different directions in order to place it in the position most favourable for winding the cable, a horizontal drum 1 is carried by a bracket 3 on which is mounted a driving motor 9, the whole being supported by a vertical pivot 4 depending from the bracket. A guide 11 is provided for facilitating the winding of the cable 10, the pull of which swings the drum and motor assembly about the pivot 4 till the drum is at right-angles to the cable, which is then approximately in a plane in which the vertical axis of the pivot 4 lies. A reducing gear 8 connects the motor 9 and the drum 1, and means may be provided at the bottom of the pivot 4 to prevent it rising in its bearing 5. A plurality of bearings 5 may be located at various positions, and the assembly may be lifted by handles 12 for insertion into any desired bearing.

Title: Method of and apparatus for controlling metal wire coating
IPC: B29C48/06
Filed: 1974-05-17
Abstract: 1433984 Coating wires MAILLEFER SA 17 May 1974 [28 May 1973] 22252/74 Heading B5A [Also in Division G3] Coated metal wires with a constant capacitance are formed by passing the wire 7 through an extrusion head 5 and then through a watercooling vat 9, the downstream position of the vat with regard to the head being varied as a function of the capacitance measured at 10. Expansible plastics material 6 is supplied by screw 4 to the annular die slot 8 surrounding the wire 7. The hot coated wire is then passed to cooling vat 9, the position of which is varied by rotation of gear 13 by motor 14, the gear meshing with toothed rack 12 attached to the underside of the vat. The capacitance is measured downstream of the vat at 10 by a gauge 11  forming one arm of a capacitance bridge, the wire being earthed. The capacitance signal generated at 11 is compared with a predetermined value and an error signal passed to the motor 14 which alters the position of the vat. The vat may in turn generate a second signal which activates heating elements 2 or cooling means in the extrusion cylinder 3 so as to return the vat to a median position. Alternatively or in addition the error signal from gauge 11 can be passed directly to the extrusion cylinder 3 as well as to the motor 14. In a further alternative the temperature of the cylinder 3 can be adjusted manually in response to an alarm produced by the vat arriving at the end of rack 12.

Abstract: 767,702. Photographic developers. KODAK, Ltd. Aug. 3, 1954 [Aug: 3, 1953], No. 22508/54. Class 98(2) A photographic developer composition, in wet or dry form comprises .an alkaline material, a 3-pyrazolidone developing agent, and gallic acid. The 3-pyrazolidone developing agent may have the general formula wherein R 1  to R 5  can be H. or alkyl or aryl groups, substituted or not. Numerous 3-pyrazolidones are specified, including 1- phenyl - 2 - acetyl - 4 : 4 - dimethyl 3 - pyrazolidone.

In examples, data illustrating the activity of developers containing gallic acid and 1-phenyl-4 : 4-dimethyl- 3 - pyrazolidone and 1 - phenyl - 3 - pyrazolidone are given. The developer may also contain sodium hexametaphosphate, potassium bromide. and iodide, and 1 - phenyl - 5 - mercaptotetrazole.

Abstract: 1475396 Interrogator responder systems SIEMENS AG 21 May 1974 [21 May 1973] 22733/74 Heading H4L [Also in Division B7] An interrogator responder system including a number of interrogator devices in a vehicle identification or location system and in which each interrogator device contains a sweep generator so that wireless, e.g. microwave signals transmitted by it are repeatedly swept through a frequency band, is such that the signals transmitted by the different interrogator devices start their sweeps at different times. This reduces mutual interference between transmitters in proximity with one another, which may result, e.g. from multiple reflections from the vehicles. These may be, for example, railway rolling stock. To ensure that the frequency sweeps start at different times, the start of one may be signalled to the next in a sequence via a delay. The sweep times may differ slightly or there may be random delays between successive sweeps from the same transmitter, these random delays being set by a random number generator.
