Abstract: 1,239,696. Photo-electric evaluation of fabrics. NIPKIP. Dec.5, 1969 [Dec. 7, 1968], No.59598/69. Heading G1A. [Also in Division D1 Apparatus for measuring the degree of creasing of a material comprises a light source 2 and lens system 3 which projects a beam of light across the surface of material 4 into a detection system comprising diaphragm 11 and photo-cell 7. The material is placed on a rotatable support 5 which together with diaphragm 11 may be enclosed in container 12. The photo-cell feeds amplifier 8 and the degree of creasing is indicated on meter 9. The apparatus is calibrated by placing an uncreased material on the stand. Before measurement a textile fabric can be creased using a device comprising two discs touching each other face to face where one has projections which, with the material, enter recesses in the other disc. The material may have a predetermined moisture content.

Abstract: 1,257,137. Lubricating. NECCHI S.p.A. 6 March, 1970 [7 March, 1969], No. 10908/70. Heading F2A. [Also in Divisions F1 and H2] An electrical motor/compressor unit has a shaft 19 mounted in a housing 17. A disc 31, attached to the shaft 19, is located adjacent a surface 32 of the housing, and when rotating, conveys lubricant 12 from a reservoir to a lubricant chamber 21, via an arcuate groove 34 which is formed in the surface 32. The groove 34 connects to the reservoir, via a cavity 22 and a hole 23 which are formed in the housing 17. Lubricant is gravity-fed through a duct 36 to a clearance 37 formed between a portion 78 of the shaft 19 and a bore 18 of the housing 17, and is conveyed, by means of grooves 39, 40 in the shaft, to the bearing surfaces. The groove 39 also conveys lubricant to a passage 41, lubricant then being collected by rotating fins 16 of a rotor 15 so as to be thrown on to stator coils 14 and effect cooling thereof. The groove 40 also conveys lubricant to a recess 42 which is formed between a portion 43 of the shaft 19 and the disc 31, the lubricant then passing through a horizontal hole 44 in a crank-pin 28 of the compressor and through a radial hole 45. Lubricant passes, through a groove 46 in the crank-pin, into a hole 47 in a connecting rod 27, and to a gudgeon-pin 26 so as to lubricate a piston 25 which reciprocates in a cylinder 24. The stator coils 14 are also cooled by means of lubricant which flows from the chamber 21, through an inclined duct 48 and on to another set of rotating fins 16. Refrigerant gas is sucked through the gap between the rotor 15 and the stator 13, issues into a recess 49, is passed to the cylinder 24, via a duct 50 and a valve (not shown), and has lubricant entrained therein.

Abstract: 1296213 Automatic steering control DECCA Ltd 19 Feb 1970 [18 June 1969] 30884/69 Heading G3R An electrical signal for steering a ship is formed by combining a control signal with a feedback signal from a capacitor the charge on which is increased or decreased incrementally according to the direction and extent of movement of a steering motor and also tends to decrease with the passage of time. As shown, any difference between a compass signal 11 corresponding to the course of a ship and a signal 10 corresponding to a desired course is applied through a suitable non-linear circuit 13 and an amplifier 15 to control an electric servomotor 16 operating rudder 18 to correct the course of the ship. Movement of a slotted disc 19 driven by servomotor 16 corresponds to the integral of the control signal applied to servomotor 16 and, by interrupting light from a lamp 21 falling on photocells 20 associated with a discriminator 22, produces pulses which add or subtract increments of charge to a condenser 25 according to the sense of movement to produce a voltage corresponding to the integral. This voltage is applied as negative feedback to the input of amplifier 15 but, to permit offset of the rudder if necessary to counteract persistent unbalance effects, a leakage resistor 27 is connected across the condenser to reduce the feedback as a function of time.

Filed: 1999-11-04
Abstract: A process for treating earth materials such as rock heaps to prevent acid rock drainage therefrom is disclosed. First, the oxygen concentration in the gas-phase of the rock heap is decreased, that is, displaced and/or depleted. This first step may be accomplished physically, chemically or biologically. Then, the gas-phase oxygen concentration in the heap is maintained at a low level. This second step may be provided for in a self-sustaining manner, like, for example, by covering the rock heap with soil and vegetation so that acid rock drainage is prevented indefinitely. Alternatively, the density of the gas-phase of the rock heap may be increased, and maintained at an elevated level indefinitely. The process is applicable to waste heaps from mining and industrial operations such as power generation and minerals processing, and to rubble collections in open and closed mines.
