Abstract: 1,186,384. Knitting machines; turning inside out. F. LONATI. 19 May, 1967 [20 May, 1966], No. 23441/67. Headings D1C and D1X. A device for turning a tubular knitted item inside out comprises a first tubular member arranged to be secured to the needle cylinder of a knitting machine to project from the lower end thereof and to rotate therewith, a second tubular member slidable within the first member to operate releasable engagement means adapted to engage with an edge portion of the knitted item relative to the first member, and suction means provided to draw the knitted item into the second member while the edge portion is held by the engagement means. As shown, a sleeve 1a is attached to the outlet of a circular knitting machine to rotate therewith, and is rigid with an outer cylinder 5a having an outlet 17 connected to a suction line. A cylinder 11 a, slidable within cylinder 5a through a sealing ring 20, is formed with lugs 19 slidably receiving rods 21 depending from a ring 14 rigid with sleeve 1a. Springs 23, interposed between lugs 19 and abutments 22 on rods 21, maintain a peripheral lip 18 on cylinder 11a spaced from ring 14. Suction is initially applied to outlet 17, whereby the welt of a stocking being knitted passes between ring 14 and lip 18. Cylinder 11a is then moved upwards to clamp the welt against ring 14, and suction is removed from outlet 17 and applied to the lower end of cylinder 11a, whereby the stocking, in the course of being knitted, passes down cylinder 11a and is turned inside out. In a modification, the inner cylinder is moved upwards to engage a series of fingers pivoted within the outer cylinder, whereby said fingers turn upwardly and outwardly to clamp the welt between the fingers and the wall of the outer cylinder. Reference has been directed by the Comptroller to Specification 1,047,123.

In the preferred embodiment a conventional video amplifier Fig. 1, comprising stages 1, 11 to 14 and a positive/ negative switch 2, the stages 11 to 14 compensating respectively for stray light, black value, gamma and colour match, is provided with switches 18a to 18f between automatic gain control signals shown originating from potentiometers 80 to 85, which switches, when activatedby signals N1 and N2, over-ride the automatic gain control signals and set the stages at unity gain. A test signal can then be passed through the amplifier and examined for distortion. As shown the signals N1 and N2 can be applied either singly or together in order to effect tests under different conditions. Suitable switching circuits 18a to 18f and amplifier stages are described Figs. 2 to 5 (not shown).

Abstract: 652,252. Grinding lenses &c. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Aug. 28, 1947, No. 23870. Convention date, Nov. 27, 1945. [Class 60] A method of operating on the surfaces of optical glasses in which a blank 1 is subjected to the action of grinding tools to bring it to a shape defined by spherical surfaces of any radius up to infinity, comprises arranging the blank in a guide which allows it to revolve about a fixed axis X-Y, subjecting the blank to the action of two tools 2, 3 having operating surfaces of the same sphericity as the required surfaces, arranging the tools on opposite sides of the blank with their centres eccentric to the blank centre and rotating them in the same direction as viewed from the same side of the blank, one of the tools being held in fixed position with the centre of curvature O<SP>3</SP> of its operating face located on the axis X-Y, while the other tool has its operating face initially spaced from its final position by a distance which gradually decreases to zero as the operations are completed. The tools are driven by electric, hydraulic or air motors 9 and 13, Fig. 5, mounted on plates 11 and 14 which are angularly adjustable by screws, vernier scales 22, 23 being provided to show the extent of adjustment. The shaft 6 carrying the tool 3 is provided with a collar 6a to locate it axially during the grinding operation, while the shaft 5 is free to move axially under the action of a spring 26 until its collar '5a comes into contact with one end of the motor 9 at the completion of the operation, the centre O<SP>2</SP>, Fig. 3, then being on the axis X-Y which coincides with the optical axis of the blank. To facilitate replacement of the blank, the shaft 5 is withdrawn axially from operative position by depressing a the other end of which engages a collar 27 secured to the shaft. The blank is mounted pedal forming one end of a bell-crank lever on rollers 4, Fig. 6, carried by arms 31 pivotally mounted on a fixed annular member 32 which rotatably supports an annular member 33 having pins 34 to press the rollers into contact with the periphery of the blank when the member 33 is rotated by a screw 35. Non-circular blanks are mounted by fitting them into a holder with a circular periphery. The tools may be of cast-iron with a supply of fluid-borne abrasive or, alternatively, may be abrasive in themselves. Rim-shaping of the blank may be effected simultaneously with the treatment of its optical surfaces, by providing tools around the blank holder. Plane-parallel plates may be produced by employing flat-faced tools the rotational axes of which are parallel to the axis X-Y. Fig. 7 shows an assembly for semi-continuous production of lenses in which the blank holders are mounted on a chassis 38 to move the blanks between the stages of production. Each stage is isolated by partitions 41, 41a which slide transversely to allow passage of the blank. Accurate location of the chassis is ensured by a system of stops and notches.
