Title: Improvements relating to the manufacture of waveguides and slow wave structures
Inventor: CROWLEY-MILLING MICHAEL CROWLE
IPC: H01P11/00
Filed: 1963-01-09
Abstract: <PICT:1061442/C6-C7/1> A process for accurately forming waveguide or slow wave structures comprises forming apertures approximately to the required size in metallic diaphragms and then electrolytically removing metal to increase them accurately to size.  Fig. 1 shows electrolytic removal of Cu from iris diaphragms of a waveguide assembly 1 using a Cu electrode 4 and an electrolyte 3 of H3PO4.  An iris hole diameter may be increased by 2/10,000 in. in 8 secs. for a current density of 1 amp./sq. cm.  The electrode 4, carried by a rod 5 insulated at 6, may be raised and lowered from iris to iris stepwise or continuously and may be of a length to extend over the distance of two irises Fig. 2 (not shown).  The rate of electrode movement may be automatically controlled, e.g. by a cam preset according to the amount of metal to be removed.  Alternatively, the rate of movement may be constant and the current varied. Electrolyte may be pumped at high velocity between the electrode and waveguide. The electrode may be rotated.  Polished surfaces to the holes are produced.

Abstract: 925,185. Glass fibre manufacture. OWENCORNING FIBERGLAS CORPORATION. Jan. 12, 1962, No. 1294/62. Class 56. Apparatus for forming fibres of glass or other heat-softenable mineral material comprises means for feeding spaced groups of streams of the heat-softened material downwardly from a supply into stream receiving passages formed in a blower disposed adjacent and beneath the means for feeding the streams, a stream receiving passage for each group of streams and the blower having chambers from which gas under pressure is discharged as high-velocity blasts into each passage through vertically spaced orifices formed in opposite walls of each passage, and means for preventing the flow of air into each passage from the side of the passage in which the uppermost orifice is formed. Molten glass, contained in an electrically heated feeder 14 fitted with a screen 21, Fig. 3, is fed through two rows of tips 18 and 20 into passages 84 where it is blasted by high-velocity steam or other gases issuing through nozzle orifices 88 and 92. The two rows of tips 18 and 20 may be replaced by two double rows. In another embodiment, Fig. 7, baffles 160 and 168 are used for controlling and redirecting the flow of blast induced air. The portion of this induced air passing through passages 170 cools the streams of glass in the region of the tips 18<SP>1</SP> and 20<SP>1</SP>. Alternative forms of baffles comprise wedges 180, Fig. 8, and abutments 190, Fig. 9. After blasting, the streams pass into a fibre forming hood fitted with applicators for spraying binder or coating material on to the fibres and at the bottom of which hood there is a reticulated pervious endless belt conveyer with a suction chamber immediately below.

Filed: 1919-01-22
Abstract: 141,815. Thompson, G. S., and Thompson, M. M. Jan. 22, 1919. Ladders.-Step-ladders have the sides of the back supports A pivoted to the sides B of the body at C, and the spread of the ladder is limited by a strut E which is hinged to the upper part D of the ladder and abuts against a cross-piece F when the ladder is open, the strut being normally prevented from leaving the cross-piece by a sliding stud or bolt G which projects from the lower end of the strut and passes into an aperture in a plate H secured to the upper edge of the cross-piece. The aperture in the plate may be #-shaped, as shown in Fig. 5, the sliding bolt being correspondingly shaped and provided with a notch which is engaged by a spring J when the ladder is extended, thereby locking the strut. A turn-buckle may be arranged to hold the spring J out of action when desired. When the step-ladder is required to be converted into a pin-ladder, the sides of the body and of the back support are made parallel to one another, the bolt N, Fig. 10, is made so that it may be completely withdrawn from the cross-piece F by hand, and the top tread O is suitably cut away so that the back supports A may be brought into line with the body B, as shown. The parts may be locked in this position by bolts beneath the top tread and passing through apertures P in the sides of the body and support. The step-ladder may also be furnished with a folding table or rest R, Fig. 12, which is hinged at T to the strut E, and is forked so as to project beneath the tread S; R<3> are blocks on the extending portions of the table which engage with the body of the ladder and facilitate the folding of the table, when the ladder is closed.

Title: Improvements in or relating to the manufacture of photographic materials
IPC: C23C14/06
Filed: 1964-01-14
Abstract: A binder free layer of a silver halide is vapour deposited under vacuum by heating a silver halide source to above its decomposition temperature.  The deposit is formed on a web of a photographic base material such as baryta <PICT:1001910/C6-C7/1> paper, an acetate film, "Cronar" or "Mylar" (Registered Trade Marks), to a thickness of 0.1-0.5 microns.  Silver bromide is the preferred halide for photographic purposes and the deposition is effected in a conventional vacuum chamber 12 in which the silver halide source is contained in a heated tungsten crucible 32 and the web substrate 29 is continuously moved past aperture 18 by rolls 23 and 24 so that the silver halide evaporated from crucible 32 condenses on the moving web.  A shutter 20 operated by hand lever 31 closes aperture 18 until conditions of deposition are stable and in the case of silver bromide the evaporation temperature is 725-765 DEG C. since the bromide decomposes at 700 DEG C. The web should be located about 3 1/2 inches from the crucible so that its temperature is about 50 DEG C. Alternatively the web may be temperature cooled by artificial cooling. Specifications 361,750, 387,967, 802,041 and 968,453 are referred to.

The bore of the bushing is preferably slightly larger than the diameter of the spindle 2 and the bobbin is driven by the frictional engagement thereof with a tapered foot 4 on the spindle supplemented by the yielding grip of the bushing 6. In a modification the bushing is relied upon for the driving of the bobbin or a second bushing may be disposed at the lower end of the bobbin to engage the tapered driving foot 4 of the spindle. The bushing at the top of,the bobbin may be removably held in the bore thereof by a split ring which may be disposed in a groove in the base of the bobbin. The Specification as open to inspection under Sect. 91 comprised a modification in which the bushing was secured in place by a metal washer forced into the bore of the bobbin above the bushing.

Abstract: 1,272,242. Tube expanding. DYNAMIT NOBEL A.G. 22 May, 1969 [13 Jan., 1969], No. 2021/69. Heading B5A. [Also in Division B3] Apparatus for altering the cross-sections of hollow, thermally deformable members, having a longitudinal axis, e.g. plastics or metal pipes, comprises a mould having an outer part, a multicomponent inner part which comprises an alternating arrangement of equal numbers of segments of large and smaller size which together form a continuous mould surface, and a conical core engaging with the inner part of the mould and longitudinally displaceable therein so that said longitudinal movement radially displaces the segments to form a continuous core. As shown the apparatus comprises an outer mould part comprising two sections 1 and 7 separated by a cavity 6 for heating fluid, an inner mould section comprising segments 2 and 2a and a core 3. The core and inner mould section are movable relative to each other by a double acting cylinder 4. The core 3 has eight inclined faces each equipped with a groove and dovetails on the segments 2 and 2a engage these grooves. The faces are inclined so that as the core moves into the inner mould part, the segments 2a are forced outwards at a greater rate than segments 2 and force the material to be shaped 9 into contact with the outer mould 7. To ensure even pressing, the inner mould section can be turned relative to the outer and the outer section 1 is preferably hinged to aid removal. When only part of the hollow article is to be shaped, the inner mould section may be shorter than the outer and the material of the hollow article may be forced outwards against a rubber membrane which is forced inwards by the heating fluid, circulating in the cavity 6 of the outer mould section. Preferred materials for the hollow article are the polymers of vinyl chloride, vinyl acetate, ethylene, propylene, butylene, isobutylene, caprolactam and polycondensates of diamines with dicarboxylic acids and of diols with dicarboxylic acids.
