Abstract: 1,192,804. Electro-phoretic deposition. FORD MOTOR CO. Ltd. July 21, 1967 [Dec. 7, 1966], No. 33632/67. Heading C7B. In a process for electro-painting an electrically conductive object which is immersed in an aqueous electrolyte containing an organic resin having ionized sites intimately dispersed with an ionized dispersal assistant, whilst passing a direct current between the workpiece to be coated and a counterelectrode, a diffusion barrier which allows a flow of liquid to pass therethrough is placed between the workpiece and the counter-electrode to form a bathwithdrawal zone in contact with the counter-electrode, from which electrolyte of reduced paint concentration and increased concentration of dispersal assistant with respect to the electrolyte in the zone surrounding the workpiece is withdrawn, replenished and returned to the zone in contact with the workpiece. The embodiment shown, for use with a resin which is anodically deposited, comprises a metal tank 11 having a plastics lining 13 and containing an electrolyte bath 33; an overhead conveyor 39 for passing objects 35 to be coated through the bath; cathode assemblies 17 which comprise a wire screen cathode 17-3 and a diffusion barrier 17-4 and which are positioned adjacent the sides of the tank; and means 17-6 for withdrawal of catholyte from the zones associated with each cathode, the electrolyte withdrawn from each catholyte zone being passed to a catholyte collection unit 19 and thence via pump 23 to a paint dispersal unit 27 for replenishment, and thereafter being returned to the electrocoating bath 33 via conduit 31. Polycarboxylic acid resins dispersed with the acid of a watersoluble amino compound, e.g. a water soluble amine or ammonia, may be anodically deposited; and resins which may be cathodically deposited may be dispersed in the bath by addition of waterionizable acidic dispersal assistants, e.g. water soluble carboxylic acids or buffered phosphoric acid.

Abstract: 847,930. Electrolytic etching and plating of semi-conductors. PHILCO CORPORATION. Nov. 5, 1956 [Nov. 4, 1955], No. 33678/56. Drawings to Specification. Class 41 A body of a semi-conductive material is locally etched or plated electrolytically by applying an electrolyte to the surface of the body to be so treated, and applying a potential between the electrolyte and a potential barrierforming element contiguous with said body and spaced from said surface, the applied potential being such that an area of said surface defined by the area of said element is suffused with minority carriers from said element and that the potential of said surface with respect to the electrolyte is of the same sign as said minority carriers so that etching or plating occurs only in the area suffused by said minority carriers. The treating electrolyte may be applied to the carrier either as a jet or by immersion therein of the body to be treated while isolating from the electrolyte the surfaces of the body other than that to be treated e.g. by means of a wax or polystyrene resist. The potential barrier-forming element may be a P-N junction, a rectifying area contact between an unstressed surface region of the semi-conductive body and an overlying material in intimate engagement therewith (a " surface-barrier contact) or a further electrolyte which may be applied as a jet. Specifications 805,292 and 824,484 are referred to. Reference has been directed by the Comptroller to Specification 805,291.

In scissors each half comprises a cutting assembly consisting of a metal cutting blade mounted on a resilient plastic blade holder provided with a finger loop, and the blade of one or each assembly is anchored at one end to the support and is adjustably secured at its other end to the scissors to tension the blade so that the plastic holder bends to press the cutting blades together. As shown in Fig. 3, hand nuts 34, 35 coact with toothed projections 36, 37 at the inner ends of metal blades 38, 39 to tension the blades and a spring metal lever 44 is held at one end by the pivot pin, is pressed under tension into a recess 47, and is secured to the outer end of the holder by riveting or by the detachable engagement of a projection 44b in a recess 46. In modifications, a fixed metal cutting blade is moulded or riveted in a recess in a plastic holder and a detachable blade, which may be double-edged and reversible, tensioned in a recess in its holder by the engagement of apertures in the blade on studs on either of the holders. The tensionable blade may be hollow-ground as shown in Fig. 9, the studs having undercut faces. In further modifications, the stud-engaging apertures are wider at one end than at the other, the tensioning is effected by a movable member having a stud to engage the tensionable blade and a serrated end or ends to engage a hand but inset in the handle associated with the other blade, or, as shown in Fig. 16, by a toothed formation of the pivot pin engaging a serrated slot.

Abstract: 603,475. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34570. Convention date, March 13, 1943. [Class 97 (i)] An ortho-pseudo stereoscopic rangefinder has two comparison planes viewed respectively by the left and right eyes, each plane having two parts, in one of which .is formed an image from one of the spaced viewpoints of the finder and in the other is an image relayed from the other comparison plane by a suitable optical system including at least one objective. As shown in Fig. 7, direct left and right images are formed in the transparent portions 15, 17 of the comparison planes 13, 14 by suitable optical systems (not shown) and are viewed as orthostereoscopic images by prisms 40, 42 and eyepiece lenses 41. The lower portions 16, 18 of the comparison planes are reflecting and the image in the portion 15 of plane 13 is relayed by lenses 45, 46 to the portion 18 ; similarly, an image in portion 17 of plane 14 is relayed to the portion 16. Both relayed images are viewed in the eyepieces as pseudo-stereoscopic images inverted with respect to the ortho images. Stereoscopic coincidence is effected by a suitable light deviator in one of the object beams. As an alternative, the lens 46 may be omitted or the lenses 45 replaced by prisms similar to the prisms 40 and the lens 46 by an objective. In a further modification, the lenses 45 and prisms 40 are interchanged, whereby the relaying beam is displaced from the directly viewed beam. A suitable prism for effecting this displacement is described. In Fig. 9, direct images are formed in the transparent portions 15, 17 of the planes 13, 14 by lenses 12 and end reflectors 11. Light from the portions 15, 17 is collimated by relay lens 60 and passes via the upper reflecting portion of the central interface 64 of prisms 62 to the eyes 25 via lenses 61, 24 and prisms 23. Some of the light from each of the portions 15, 17 passes through the transparent lower portions of the interfaces 64 to be imaged respectively on the reflecting portions 18, 16 by the lenses 60 and are also viewed in the eyepieces as pseudo-stereo images. A light deviator 30 effects stereoscopic coincidence.
