Filed: 1939-03-08
Abstract: 526,130. Abrasive articles. TENNANT, W. J. (Carborundum Co.). March 8, 1939, No. 7571. [Class 60] In the manufacture of abrasive articles employing silicon carbide granules bonded together or mounted on a backing, the granules are treated to form thereon a uniformly distributed and integrally united surface film of silica, whereby stronger adherence between the granules and the bond is achieved. The granules are formed by crushing a mass of silicon carbide and are mixed in a concrete mixer or a mill with 0.3 per cent. to 0.8 per cent. by weight of an oxidation accelerator, for example, a metallic oxide such as iron oxide, lead oxide or nickel oxide. The mixture is then roasted under oxidizing conditions in a rotary kiln until the granules have a silica content of from 0.5 per cent. to 5 per cent. of the weight of the granules, the preferred figure being 1.75 per cent.

Title: Moving iron type instruments
Inventor: OKADA HIDEKAZU
IPC: G01R5/14
Filed: 1968-02-16
Abstract: 1,212,383. Moving iron instruments. TOKYO SHIBAURA ELECTRIC CO. Ltd. Feb. 16, 1968 [Feb. 16, 1967; Feb.3, 1968 (3)], No.7750/68. Heading G1Q. In a moving iron type instrument the quantity to be measured is applied to an exciting coil 7 secured within a casing 14 while a fixed vane 9 and a rotatable vane 6 are mounted parallel with one another outside the coil, the rotatable vane being mounted near one end on a shaft 1, to be rotatable about an axis normal to the plane of the vane and the faces of the exciting coil, both vanes being magnetizable by the field produced by current through the coil. The periphery (9a Fig. 3) of the fixed vane has a contour such that the distance between it and the tip 61a of the rotatable vane gradually increases as the rotatable vane turns in response to increases in the quantity being measured. Mutual repulsion between the vanes occurs when N current passes through the coil, but decreases as the rotatable vane turns, until balance with the restoring torque of a spring 5 is achieved. The pointer 4 carried by the rotatable vane then provides the measurement indication. By appropriately shaping the contour of the fixed vane, a linear scale over nearly 360 of rotation is achieved. As shown in Fig. 3a, the movable vane 61 may have a radius greater than that of the fixed vane, which progressively reduces. Alternatively Fig. 3b not shown) the movable vane radius may be smaller than that of the fixed vane which progressively increases. In alternative embodiments are variously shown the way in which the periphery of the fixed vane may be varied to ensure that the rotatable vane rotates in the proper initial direction, the addition of a magnetic stop at the end of the travel path, alternative shapes for the rotatable vane, and various types of mounting arrangements for the rotatable and fixed vanes and the exciting coil. The instrument may incorporate two sets of fixed and rotatable names, one at each side of the exciting coil, mounted on a common shaft.

Title: Improvements in or relating to Flying Spot Scanners.
Inventor: CROWDER NORMAN ALLISON
IPC: H04N9/802
Filed: 1967-02-17
Abstract: 1,173,512. Television. COLUMBIA BROADCASTING SYSTEM Inc. 16 May, 1968 [17 Feb., 1967], No. 7805/67. Heading H4F. A flying-spot scanner is arranged to scan a cinematograph film, which is moved at constant speed, with a raster of lines in which the frame scan is in the same direction as, but at half the speed of, the film. With this arrangement the film moves double the frame height while a single frame is being scanned so that alternate frames only of the film are scanned and the skipped frames may contain chrominance information or a second independent sequence of luminance information. The film may comprise a double track of frames, one track (18) containing two independent sequences of luminance information and the second track (20) containing corresponding sequences of chrominance information, Fig. 1 (not shown). An optical track (22) containing synchronizing signals is arranged between the luminance and chrominance tracks and magnetic stripe audio tracks (24, 26) for the two sequences of pictures are located at the edges of the film. Such a film may be scanned by the apparatus shown in Fig. 2 in which the film 10 is moved through a scanning gate 40 at constant speed and laterally adjacent luminance and chrominance frames are simultaneously scanned by rasters derived from a conventional C.R.T. flying-spot scanner 42 by means of a split lens system 44. The light transmitted by the film is picked up by two photomultipliers 46, 48 which feed the luminance and chrominance signals to a colour receiver. A light source (58) is arranged to illuminate the optical synchronizing signal track, the transmitted light being picked up by the luminance photomultiplier, the synchronizing signals being subsequently separated from the luminance signal and utilized, preferably with a flywheel circuit, to control the time bases 62. The light transmitted by the synchronizing track may alternatively be picked up by a separate detector such as a phototransistor. The audio signal is derived from the appropriate magnetic track by a pick-up head 54. Single track films containing alternate frames of luminance and chrominance information together with an optical synchronizing track (22) at one edge and a magnetic audio track (24) at the other edge, Fig. 1 (a) (not shown), may be utilized, in which case two adjacent frames of the track are simultaneously scanned. Single track films containing two interleaved sequences of luminance information together with magnetic tracks at both edges, Fig. 1(b) (not shown), may be utilized, in which case only a single frame is scanned at a time and the audio and synchronizing signals are obtained from the appropriate magnetic track.

A dispensing apparatus for powdered materials comprises a hopper 10, drum 14 having openings 16 in its periphery, a sheet 17 of elastic material covering the openings and a restraining sleeve 18 fitting over the drum with apertures corresponding with the openings 16, and means for applying suction to the openings 16 to draw in the elastic material so as to form pockets 22 and for releasing the suction to cause ejection of the charges at a discharge position b. As described, the openings 16 are arranged in staggered axial rows on the drum surface, Fig. 2 (not shown). Valve plates 32 engage the axial faces of the drum and apply vacuum to a channel 33 whereby pockets 22 are formed at position a. During the anticlockwise rotation of the drum, a retaining sheet 23 closes the mouths of pockets 22, and at position b, pressure is applied through passages (35), 21 to eject the powdered charge to a half-capsule 24, the capsules then being formed as described in Specifications 957,840 and 881,022. The charge may be compressed while in the pocket 22. Fig. 3 (not shown) reveals an arrangement where, prior to passing under the retaining sheet 23, the charge is compressed between a resiliently loaded backing plate (42) flush with the drum surface, and the elastic pocket base forced outward by compressed air. In Fig. 5 (not shown), compression occurs after emerging from sheet 23 but before discharge, and against a surface of a mounting block for the sheet. The volume of the pockets may be altered by varying the suction pressure. The invention may be applied to filling bottles, ampoules, packets &c.
