Filed: 1971-12-17
Abstract: 1367108 Measuring thickness of paper MEASUREX CORP 17 Dec 1971 [14 Jan 1971] 58721/71 Heading G1N The thickness of a travelling paper web 18 is measured by interposing it between two parts of a magnetic circuit carried on respective rubber diaphragms 23, 23' movable towards and away from the paper by the application of gas-pressure and vacuum respectively. The magnetic circuit comprises a U-shaped ferrite core 71 carrying two windings 74, 75 connected in series with a capacitor in the feedback circuit of an oscillator Fig. 5 (not shown) to control its frequency. The legs of the core extend through the diaphragm 23 and through a ruby or sapphire shoe 76. Leg 72 is rigidly fixed in the shoe by epoxy glue and leg 73 is fixed by room-temperature-vulcanizing rubber to accommodate thermal expansion. A ferrite shoe 81, possibly of a single crystal, on diaphragm 23' completes the magnetic circuit. Stainless steel bearing rings 84, 84' and annular plates 86, 86' increase stability of the diaphragms. Electrostatic build-up is prevented by grounded plates 87, 88 or the diaphragms may be made of electrically conductive rubber. Each diaphragm has an annular or horse-shoe shaped corrugation 24 near its periphery which is clamped between a plastics ring 26 and a retaining ring 27. Piston valves 48, 49 are operable by a rotational solenoid 54 to connect the chamber 21 above the diaphragm 23 to the vacuum or pressure side of a vortex fan pump (36), Fig. 3 (not shown) for raising or lowering the diaphragm 23. The surrounding hood includes two other diaphragms 62, 63 and is purged with dry nitrogen led in at 15 and escaping through various leaks. To adjust the output of the pump, different apertures (66) in a pivoted disc (64) are selected to control the size of a leak (67). The apparatus, together with other apparatus responsive to basis weight and moisture content, is traversed across the paper on beams (11, 12), Fig. 1 (not shown). The moisture content measurement may be used to correct the thickness measurement to a standard moisture content.

Title: Improvements relating to exposure control systems for photographic apparatus
IPC: H03F3/347
Filed: 1969-12-16
Abstract: 1293771 Photo-detector circuit POLAROID CORP 16 Dec 1969 [16 Dec 1968] 61238/69 Heading G1A [Also in Division G2] A photographic exposure control which provides a linear response with variations in illumination has a photo-voltaic cell 10 which operates in the current mode to generated a linear signal representative of light incident thereon from a scene to be photographed when working on to a low input impedance, the signal being fed to an amplifier 12 providing a control signal which regulates a controllable exposure parameter in accordance with the control signal. The photovoltaic cell 10 is positioned behind a diaphragm slit (236) Fig. 7 (not shown) formed in an extension of a camera objective diaphragm blade. The amplifier 12 is a differential amplifier, preferably of infinite gain, infinite input impedance, and zero output impedance. The current generated by the cell 10 is limited by its own impedance by providing a feedback circuit 18, 20 between the amplifier input 14 and output 22 which produces an apparent zero input impedance. A potential difference across input leads 14 and 16 produces a current of opposite polarity at the output of capacitor 24 which counteracts any differential signals voltage caused by the cell 10 across the input leads 14, 16. The output 22 of the amplifier feeds a Schmitt trigger circuit 50 which continuously energizes a solenoid coil 44 until the output reaches a predetermined level, whereupon de-energization of the solenoid coil occurs. The solenoid coil controls the release of a closing blade of a shutter Fig. 6 (not shown) or a variable aperture Fig. 7 (not shown).

Patent GB-730469-A (GB)
IPC: C23G1/00
Abstract: 730,469. Cleaning and modifying metal surfaces. HYAMS, M. March 31, 1953 [Dec. 31, 1951 ; Jan. 5, 1952], Nos. 30451/51 and 413/52. Drawings to Specification. Class 82 (2). [Also in Group XXIX] Metal surfaces are treated to effect cleaning or coating by a process in which aqueous liquid is sprayed on to, and reacts with, the surface being treated, and in which the liquid when passing as spray to the surface, contacts with heated material the temperature of which is in excess of 180‹ F. and above the temperature of the contacting spray. The spray may thus be increased in temperature or the latent heat of evaporation of the spray may be provided. Steam may be used as the heated material and may additionally also act to cause the spray. Acidic cleaning fluids or a surface modifying agent may be used as the treatment liquid, the process being particularly useful for spraying- aqueous solutions with inverse solubility. The Specification refers to treating iron, zinc or cadmium surfaces with the ortho phosphate of a heavy metal or of an alkaline earth metal, specifically of cadmium, barium, zinc, calcium, manganese, cobalt, nickel, or ferrous iron. Iron surfaces may be treated with ferrous dihydrogen ortho phosphate or sodium dihydrogen phosphate. Aluminium surfaces may be treated with sodium carbonate and chromate. Copper, nickel, chromium and stainless steel can be treated with oxalic acid, ferrous zinc or cadmium, or aluminium can be treated with ortho phosphoric acid and an ortho phosphate of sodium, potassium, magnesium or ammonium, together with a phosphate of a non-inhibiting organic base, e.g. triethanolamine phosphate. Such solutions may incorporate a nitrite, nitrate or sulphite as an accelerator. Etchpriming can be carried out using ortho phosphoric acid and an alkyd resin. Examples are given, described with respect to diagrammatic drawings.
