[Also in Division H1] Electro-hydraulic crusher comprises a vessel 1, electrodes 3 for immersion in liquid 2 and a capacitor C 1  across the electrodes. A pulse transformer T charges capacitor C 1 . In operation, D.C. charges a reservoir capacitor C 3  and when a thryratron V is triggered into conduction by a pulse generator 5, a capacitor C 2  in series with the primary discharges across the transformer primary, the stepped-up pulses charging C 1  which in turn discharges via the electrodes 3. Transients are suppressed by an inductor L 3 . A rectifier D 1  holds the voltage on C 2  at twice the voltage on C 3 . The voltage across R 1  is displayed on an oscilloscope to facilitate adjustment of the gap. If the gap fails to break down, the energy fed back from C 3  is dissipated by a diode D 2  and resistor R 2 .

Abstract: 1,229,117. Severing ceramic bodies. CARBORUNDUM CO. 2 Sept., 1969 [13 Sept., 1968], No. 43385/69. Heading B5E. A method of severing a ceramic body 1 comprises applying a boron nitride containing coating 3 adjacent a desired line 2 of severance, and thereafter locally heating the body along the line whereby localized thermal action causes the body to sever along the line. The body may be of alumina, magnesia or zirconia and in the form of a tube, brick, rod, tube or the like. The boron nitride coating, which may also contain a phosphate binder, is applied to one or both sides of the line 2, the line being covered by a band while coating or the area of the line may also be coated initially and the coating removed in the area of the line by a stylus or hard pencil. The coating may be applied by a brush, roll, dipping or spraying. When the coating is dry, heat is applied to the line by one or more gas burners 5, such as oxyacetylene torches.

Abstract: 1,231,183. Subtitling films. GEVAERT-AGFA N.V. May 7, 1968 [May 12, 1967], No.22221/67. Headings G2A and G2C. A material comprises a processed photographic layer bearing a visible image and a waterpermeable layer thereon comprising a dispension of hydrophobic particles of a synthetic thermoplastic polymer in a hydrophilic binder and which layer becomes less water-permeable by heating or by subjection to pressure. Preferred materials of the water-permeable layer are those disclosed in Specifications 1,139,891 and 1,160,221. Graphic information, such as sub-titles, is produced in such a material by imagewise heating or pressing the water-permeable layer and then either (a) selectively removing the waterpermeable areas of the layer by using an aqueous liquid or (b) contacting the layer with an aqueous liquid which penetrates into the water-permeable areas to physically and/or chemically charge the coinciding areas of at least one lower layer so a visible image is formed or can be formed by subsequent non-differential treatment of the material. As shown, a black-and-white or colour positive movie film 1 is coated with a water-permeable heat- and pressure-sensitive layer 7 (e.g. a dispersion of polyethylene and carbon black in polyvinyl pyrrolidine or animal glue) and imagewise exposed to a positive 10 of the text to be reproduced using flash lamp 9 rendering the heated areas water-impermeable. The exposed film passes into bath 15 which contains a solution 16 to etch the silver through the unheated and waterpermeable areas of layer 7. Solution 16 may alternatively bleach a dye in the emulsion or contain a dye to colour the emulsion. The waterimpermeable areas of layer 7 are removed by rubbing roller 21 in rinsing bath 19 leaving a titled movie film. For titling negative movie films, a negative titler is used and there is no removal of the water-impermeable areas.

[Also in Division E1] A process of cold forming structural steel shapes having transverse sections of enclosed form comprises passing a round welded steel tube through successive forming rollers to progressively deform the tube by forcing its side portions together, forming a web of parallel touching thicknesses of the wall of said tube while flattening its top and bottom surfaces to form flanges above and below said web. In forming the steel tube a coil 30 of hot or cold rolled steel is passed through a slitter 33 and wound into slit coils 35 by a winder 36 (Fig. 1). The slit coils are joined and wound on a larger reel and the strip then formed into a tube and longitudinally welded. Sets of vertically mounted rollers 61-68 and co-operating horizontally mounted rollers 71-78 (Figs. 9 to 16, not shown) progressively deform the round tube into an H-beam 59 (Fig. 7) the tube weld 48 being situated in the centre of the web 60. The beam is cut into lengths by a shearing device comprising a pair of clamps 86, 87 (Fig. 17) and a shear blade 88 (Fig. 18). A channel section beam (Fig. 21) can also be formed by this process.

Abstract: 1,257,508. Opthalmic apparatus. BATTELLE DEVELOPMENT CORP. June 23, 1969 [July 5, 1968], No.31629/69. Heading G2J. A method of determining the contour of the cornea, to aid in fitting contact lenses, comprises projecting an illuminated slit 89 on to the cornea of an eye 13 and recording an image thereof on film 99. The slit 89 is curved, and means may be provided to obtain a side view of the cornea and to locate the major and minor axes of the cornea so that only two recordings are required. In a preferred embodiment a vertically moveable forehead/chin rest (117, 115) Figs. 5-7 (not shown) and a horizontally moveable frame (101) Figs. 5-7 (not shown) carrying the optical apparatus shown in Fig. 1 are adjusted to centre and focus the apparatus on eye 13. This condition is achieved when an examiner 47 viewing through eyepiece 53 sees the cross-hair 43, the side view image 61 and the front view image (dotted lines 57, 59 in Fig. 2) aligned as shown in Fig. 2. The side view image 61 is obtained by reflection with mirrors 23, 25, 27, 29, 31 to a lens 33 which focuses via a beam-splitter 37 the side view image at reticle 35 where an enlarged front view image passed through an aperture 15 in mirror 17 is also focused by a lens 39, the combined images then being focused by lenses 49, 51 and eyepiece 53 for an examiner 47. The corneal major and minor axes are now located by rotating the optical apparatus in bearings about axis 65 until the images of illuminated adjustable targets 69 projected on to the cornea to be reflected through the front view optical system and an inserted doubling Wollastan prism 73 are aligned Fig. 3b (not shown) when viewed through eyepiece 53. After an axis has been located the cornea is photographed by tripping flash 81 and the shutter (not shown) of a wide angle camera lens 83 so that an illuminated image of the cornea having a thin, curved line of light projected thereon by slit 89, lens 91, mirror 93, lens 95 and mirror 17 may be recorded on film 99 at an effective angle of 90 degrees to axis 65 due to reflection by mirror 97 through lens 83.

Abstract: 1,258,952. Electro-photographic copier. EASTMAN KODAK CO. July 25, 1969 [July 30, 1968], No.37405/69. Heading G2H. In an electro-photographic apparatus in which a photo-conductive member is recycled through a number of processing stations including a development station with a development electrode the bias applied to the electrode is increased automatically after a predetermined number of cycles thus compensating for deterioration of the photo-conductive member, due to residual toner, which causes development in background areas. As shown, the number of copies produced is determined by sensor 18 and counter 17 and a signal applied to motor 22 to vary the potential applied to magnetic brushes 9 and 10 after a predetermined number of cycles. The adjustment of the potential may be linked with other operating elements of the apparatus e.g. the drive chain on the toner dispenser and the variable potential may be applied to a backing electrode, Fig.4 (not shown).

A bearing housing 1 having communicating openings 7 at opposite ends is protected during the last stages of manufacture and during transit by means of a hollow closure member 9 having two end walls 10 which co-operate with each opening in the housing to prevent foreign matter from entering the housing. The hollow member is filled with lubricant and has an opening 13 for the lubricant provided in one of the end walls. The portion of the member between the end walls is in the form of a bellows 11 so that the length of the member may be adjusted to the length of the bearing housing, and also to facilitate the expulsion of lubricant. A groove 6 may be provided in the wall of each housing opening in which the end walls of the closure member may be inserted. The housing is in two parts 2, 4 secured by bolts (3, Fig. 2, not shown). The closure member is inserted in one of the parts and then into the other part when the two parts are brought together. Instead of engaging a groove in the housing, the end walls may engage the outer or inner surface of the housing.
