Title: Method and apparatus for testing a pin hole detector
IPC: G01N21/894
Filed: 1950-07-31
Abstract: 683,086. Photo-electric pin-hole detector. CARNEGIE - ILLINOIS STEEL CORPORATION. July 31, 1950 [March 2, 1950], No. 19090/50. Class 40 (iii). A pin-hole detector type having a light source and photo-cell on opposite sides of a strip is tested by an auxiliary light source, the illumination of which is adjustable in intensity and duration to correspond to a particular size of pin-hole and speed of strip. As shown, light passes from a source 22 through the strip under test to a photo-cell 24 situated below the strip. This photo-cell is paralleled with a further photo-cell 68 situated near a glow tube 38. The additional cell may be omitted, when the light source 38 acts directly on tube 24, but this is stated to cause instability in the electric circuits. When it is desired to test the instrument, a button 60 is pressed, operating a relay 58 which feeds a voltage determined by the setting of potentiometer 52 to the lamps, and a further slow-to-operate relay 66 which opens the circuit of the lamp after a period determined by the setting of a further potentiometer 50. The potentiometer may be calibrated to indicate belt speed and pin-hole diameter. Specification 662,612 is referred to.

Title: Joint prosthesis
IPC: A61F2/30
Filed: 1977-05-06
Abstract: To improve the compatibility and mechanical strength, the joint prosthesis essentially consists of carbon reinforced with carbon fibres and has a modulus corresponding to the modulus of elasticity of the bone tissue. Compliance with this virtually rules out loosening of the prosthesis caused by resorption or other changes in the tissue. To improve adhesion of the prosthesis, a part of the prosthesis is provided with a layer of glass ceramic, and the part of the prosthesis which is designed as sliding surface has a layer of packed sintered aluminium oxide as means to reduce wear.

Abstract: 588 , 0 4 3. Facsimile transmitters. YARBOROUGH, E. H. COOKE-. Oct. 7, 1944, No. 19285. [Class 40 (iii)] [Also in Group XXXVIII] A transmitter for enabling writing matter to be transmitted as it is executed is formed by a flexible sheet with a conducting backing stretched across another similar sheet which is rigid or rigidly supported with its conducting surface presented to the conducting surface of the other sheet. The two conducting surfaces are maintained at different electric potentials and signals are produced by pressing the upper surface into engagement with the lower surface causing currents to flow through the point of contact which set up potential differences between the ends of the sheets which are proportional to the co-ordinates of the point of contact with reference to' axes through the point at which the potential drops between each end of each sheet and the point are equal. In Fig. 1, the sheets are constituted by crossed strips 1, 2 of recording paper with metallised backings. The strip 2 is clamped directly on base 3 by end-clamps A, D and strip 1 is clamped by end-clamps B, C and extends at right angles across 2, but spaced slightly therefrom. Each end-clamp is connected through a resistance R1, R2, R3 or R4, Fig. 2, to a source of potential, the resistances connected to each strip being equal and of large value compared with the resistance of the strip. Each strip is connected to an amplifier, Fig. 3 (not shown), which is unaffected by push-push variations so as to eliminate the effect of varying contact resistance at the stylus point. The amplified voltage may be limited to avoid excessive operation of the receiver which may comprise a 'cathode-ray oscillograph or an electromagnetically operated stylus.

Abstract: 919,684. Electrophotographic plates. AGFA A.G. May 30, 1961 [June 1, 1960], No. 19528/61. Drawings to Specification. Class 37. In a process for the production of sensitized electrophotographic material the initial step is the preparation of a dispersion of a sensitizing dye and photoconductive zinc oxide in a non- polar water-immiscible organic solvent having a boiling point below 180 C. and a dielectric constant below 10 and in which the dye and the zinc oxide are no more than slightly soluble; this dispersion is then mixed with a solution of a film-forming insulating binding agent and the mixture cast on to a sheet-like conductive support and dried. The initial dispersion may be prepared by ball-milling the dye and oxide in the presence of the non-polar solvent, the dispersion being subsequently heated for a period to a temperature just below the boiling point of the solvent if desired. The support for the mixture is of conductive paper, other conductive material, or of material coated or impregnated with conductive material. Numerous examples of sensitizing dyes, of non- polar solvents, and of synthetic organic materials which may be used as the insulating binder, are given in the Specification.

Title: Improvements in or relating to metal-coated magnetic powder
IPC: H01F1/00
Filed: 1957-06-21
Abstract: Prior to metallizing magnetic powder by e.g. halide diffusion or electrolytic means, major projections on the particles of the powder are broken off by subjecting it to a running-in process, i.e. a process in which the particles are caused mutually to abrade one another.  Thus ferorus powder may be coated with chromium or aluminium and used in an electromagnetic powder clutch.
