[Also in Division H1]  A dual band tuning arrangement comprises an insulating plate 1, Fig. 1, having a conductive coating 2 on one surface and a conductive strip, e.g. 3, on its opposite surface, which in association with the coating forms a strip line capable of resonance in the U.H.F. band and a lumped constant reactance, e.g. 6, capable of resonances in the V.H.F. band mounted in close proximity to said strip, the conductive coating forming part of a screen for the lumped reactance. Screens 13 may be provided to separate individual tuning circuits, a screening box 14 provided with a lid (not shown) surrounding the tuner. Alternatively a common base-plate 15, Fig. 2, which can be a metal plate or an insulating plate coated on one or both sides with a conductive layer, is assigned to both the strip line resonant circuits for U.H.F. and the lumped constant reactances for V.H.F. The tuned circuits for U.H.F. are applied on insulating plates 16, 17 in the form of conductive coatings 18 and 19 on the two faces of the plates, which are parallel and inserted or soldered into the common base plate 15. In the case of a bandpass filter two plates 16 and 22 may be joined in such a way that the faces carrying line conductors 19 face away from each other; coupling is effected by means of a hole 23 in the continuous coating 18.

Title: An electrolytic descaling method
IPC: C01B13/36
Filed: 1964-12-14
Abstract: In a method of electrolytically descaling a ferrous material such as Ni or Ni-Cr steel using a solution as described in Specification 1,082,409, the soluble fluoride being optional, the metals dissolved during electrolysis are recovered, e.g. by adjusting the pH of the solution to 3 to 5 by adding sulphuric, hydrofluoric and/or nitric acid to precipitate iron hydroxide, removing the iron hydroxide, then raising the pH to precipitate additional metal ions as their hydroxides and removing these hydroxides; e.g. chromium hydroxide may be precipitated at a pH of 5 to 6 and nickel hydroxide at a pH of 6 to 8, the pH being adjusted by adding alkali metal hydroxide (NaOH and/or KOH). After removal of hydroxides, the solution may be recycled for use as electrolyte in further descaling, the pH being adjusted to 6 or 7.

Abstract: 1479890 Drill feed control THOMAS RYDER & SON Ltd 10 Oct 1974 [9 Nov 1973] 52107/73 Heading B3C [Also in Division E2] A device for controlling the feed of a drilling unit having a shaft 2 parallel to the drill spindle and movable in translation therewith comprises a body or block 1 lockable to the shaft by means of a pivoted apertured plate 3, biassed into the shaft-gripping locked position by a spring loaded bolt 5. In use in a "peckfeed" drilling machine, the shaft 2, body 1 and spindle are first retracted, block 1 is then stopped by a stationary "reset" stop 13 which releases the device from the shaft due to relative motion of shaft and block. The shaft, spindle and device are then fed forwardly with the device locked due to spring 7, at a fast rate until the face 14 actuates a feed controlling switch (not shown) to slow down the rate. Thereafter nut 11 contacts "stand-off" stop 15 and the device is released and drill feed continues. On retraction in accordance with "peck feed" operation the device moves with the shaft but does not contact stop 13. "Peck feed" continues at the fast rate changing to slow rate controlled as before .

Abstract: 1,237,218. Crimping fibres. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 Nov., 1968 [20 Nov., 1967], No. 52711/67. Heading D1F. Polyester e.g. polyethylene terephthalate, filamentary tow (and fibres stapled therefrom), having primary and secondary crimps in different planes and of frequencies less than 10 and 0.5-2.0 with overall crimp exceeding 15% which provides for ease of fibre opening with retention of adequate fibre cohesion, are prepared by a stuffer-box crimping and heatsetting process. A tow of parallel filaments in the form of a flat sheet of uniform thickness and consistency is fed into the crimper wherein primary crimp is controlled by the back pressure and secondary crimp is controlled by the selected density (denier per inch width) of delivered tow. The filaments are heated after crimping and in their undisturbed crimped and folded configuration by a fluid, such as steam, none of which contacts the tow until crimping is completed. In the crimper shown, filaments of a tow fed by rolls 16 are crimped in zone A, then heated and stabilised in zones B, C and, optionally, D, by steam supplied to chamber 18 and exhausted from chambers 17 and 19. These chambers are contained in divergent compression chamber side-members 12 and 13 to one of which is hinged a loaded door 20.

Abstract: 1463370 Finishing fabrics STOTZ & CO AG 13 Dec 1974 [21 Dec 1973] 53993/74 Heading D1S A textile fabric of inherently uniform stiffness has areas of reduced stiffness formed by external action. The fabric may be woven, knitted or non-woven or a laminate of two more layers and may be dyed, rendered dirt- or water-repellent, crease resistant or fire resistant. The uniform stiffness may have been achieved by impregnation with a stiffening material or with cross-linkable polymer and subsequent cross-linking, by coating, by the use of threads or fibres of stiffness greater than that of other components of the fabric, or by joining together of two fabrics by an adhesive. At the areas of reduced stiffness the fabric may have a diminished sheet weight or a diminished thickness. The areas of reduced stiffness may be produced by severing threads or fibres, chemical decomposition, grinding, milling, brushing, abrading, sand blasting, embossing, squeezing, cutting, pricking, boring, or electroerosion or by treatment with ultrasonic sound, a laser beam, radiation from radio-active materials, ultraviolet radiation, infra red radiation, microwaves, a plasma beam or heat. Chemical decomposition may be effected by treatment with a gas, a liquid-or a mixture thereof. Heat treatment may be effected by blowing, compressing or sucking a hot gas or a hot liquid, or a mixture thereof, through the fabric.
