Title: Methods of and apparatus for manufacturing abrasives and the improved abrasives resulting therefrom
IPC: B05C19/02
Filed: 1934-02-05
Abstract: 433,128. Coated abrasive articles. MINNESOTA MINING & MANUFACTURING CO., 791, Forest Street, St. Paul, Minnesota, U.S.A.-(Assignees of Carlton, R. P.) Feb. 5, 1934, No. 3732. Convention date, March 23, 1933. [Class 6b] In manufacturing coated abrasive articles such as sand paper and emery cloth, particles of the abrasive are propelled into position on the articles by subjecting them to the combined action of mechanical and electrical or magnetic forces which move them against the force of gravity, with the object of causing the grains to be deposited with their longer dimensions perpendicular to the surface of the article to improve the cutting properties. In the apparatus shown, the abrasive grains are deposited from a hopper 13 on to a conveyer belt 12 which carries them beneath a travelling paper web 11 the under surface of which has been coated with adhesive by passage over a roll 7 rotating in a bath 9 of the adhesive. At the point at which the grains are to be deposited on the paper web the conveyer 12 is agitated vertically by a beater 15 below it, causing the grains to be thrown upwardly ; at the same time the grains are subjected to the upward force of an electrostatic field between electrodes 19, 20 arranged respectively below the conveyor and above the paper web 11. The agitation of the conveyer may be insufficient alone to throw the grains on to the web, the necessary additional force being supplied by the electrostatic field, which at the same time produces the desired orientation of the grains on the web. In a modification the mechanical forces for lifting the grain are produced by air jets from nozzles arranged below the conveyer, which is pervious to the air, and the lower electrode may be arranged below the nozzles or formed bv the nozzles themselves. In either modification, the electrostatic field may be replaced by a magnetic field produced by an electromagnet situated above the paper web, the grains, if not themselves magnetic, being coated with a magnetic material or otherwise treated so that they are attracted by it. The process may be used for applying a portion only of the abrasive, the remainder being deposited by the usual gravity process.

Abstract: 1,71,754. Lens testing apparatus. CARL-ZEISS-STIFTUNG, [trading as CARL ZEISS]. Jan. 28, 1965 [Feb. 8, 1964], No.3773/65. Heading G2J. A vertex refractionometer comprises an illuminated optical system for projecting, through an eyeglass 11 to be tested, a test mark 1 on to a screen 5, manually operable means for moving the test mark along the optical axis and further means for rotatably adjusting the test mark about the optical axis, and a support 2' for locating the eyeglass 11 in the optical path, the test mark being formed by lines which cross each other at right angles and being arranged perpendicular to the optical axis. The test mark is moved axially by a rotatable knob 8 connected to the test mark support by a rack gearing 8'. A further rotatable knob 1' is coupled to the test mark 1 by a bevel gear 1" to effect rotation of the test mark. The mark comprises a plurality of heavy lines intersected by a plurality of thin lines. When the eyeglass 11 is placed in the optical path, the test mark is moved axially until the heavy lines are sharply focused. Any distortion of the thin lines due to astigmatic correction is removed by rotation of the test mark. A scale drum 9 which records the spherical refraction value of the eyeglass is then coupled to a second scale drum 10 which records its cylindrical refraction value on moving the test mark until the thin lines are sharply focused. The rotation of the test mark is measured on a circular scale provided on the screen 5 in order to determine the angular position of the cylindrical axis of the eyeglass.

Abstract: 451,510. Feeding sheets. BACKHOUSE,-H. T., 12, Melina Court, St. John's Wood, London. Feb. 6, 1935, Nos. 3890/35 and 929/36. [Class 100 (i)] In an automatic sheet-feeding device of the kind in which the separation of the top sheets of the pile is effected by means of suckers which are moved towards and away from the top of the pile to grip and lift a portion of each sheet in turn, the suckers are constructed so as to be angularly adjustable while the machine is in motion about an axis parallel to the plane of the upper surface of the pile and transversely to the direction of feed. As applied to a machine of the kind described in Specification 427,041, the suction device 16 is moved to and from the pile by means of an oscillating bell-crank lever 1 operated by a cam 4, and the sucker is moved outwards to stretch the sheet by means of a roller 10 carried by a fixed bracket 11 on a cam surface formed on a projection 13 attached to the carrier 8 of the sucker which is mounted on a horizontal pivot 9 of the arm 7 of the bell-crank lever 1. The head 14 in which the sucker is mounted is adjustable about a pivot 15, while the machine is in motion, by means of a nut 22, rod 21, bell-crank 19 and rod 18 connected to an arm 17 on the suction head and to the lever 19 by means of ball-and-socket joints. An adjustable presser member 23 is mounted in an extension of the arm 7 of the bell-crank 1 in front of the sucker 16. In a modification, an additional adjustable presser member is mounted behind the sucker 16. In a further modification, Fig. 3, the suction device 33 is carried by a spring-pressed piston 34 mounted in a holder 31 supported by a pivot 32 in the pivoted arm 8 which can move outwards to stretch the sheet under the action of a vertical cam on the roller 10. The suction device 33 is moved forwards and upwards by the piston 34 when the air pressure is reduced in the suction device, and the device 33 can be adjusted about the pivot 32 by means of a screwed rod 45 operated by a knurled head 48 and engaging a screwed nut 47 attached to the arm 8. The head 31 is fitted with a spring-controlled adjustable front presser member 36, and with a rear adjustable presser member 43. In a further modification, the position of the suction member relatively to the top of the pile can be adjusted by fitting a screw in the upper limb of the bell-crank 1 in such a position that it bears against a shoulder on the bracket 11. Specification 451,510 also is referred to.

Alternatively the adjustments of the elements may be effected by projecting the representation on to them. The representation may be complete or a draft or outline sketch may be used. The process is carried out by means of the apparatus shown, in which the elements, in the form of strips, are mounted in apertures 25 in a carrier 23 which is slidable vertically in a block 22 mounted to slide horizontally on the support 5. A support 7 carries a vertical slide 11 in which is a horizontal slide 12 having a rotatable insertion 13. On the insertion 13 is mounted a frame 14 carrying the screen 17 bearing the representation, and a dark slide (not shown). The supports 5 and 7 are connected by bellows to a support 1 having a lens 2 and shutter 4. The supports 1 and 5 are connected by links 31, 32 to a carriage 33 moving on a cam rail 36.
