Abstract: 725,872. Magnetic dust structures. MINNESOTA MINING & MANUFACTURING CO. May 18, 1953 [May 21, 1952], No. 13864/53. Drawings to Specification. Class 38 (2). A magnetic recording medium such as a tape comprising magnetically orientated, magnetically anisotropic ferromagnetic particles in a binder, has a substantially identical ratio of output to input amplitude in both directions of travel at all frequencies, and a ratio of values of retentivity in the travel and cross-wise directions of at least 1.3. Circular iron oxide particles may be dispersed in a solution in a suitable solvent of such film-forming organic materials as plasticized cellulose esters or ethers, polyvinyl resins, acrylate resins or blends of polyvinyl resins with rubbery butadiene acrylonitrile polymers. The mixture is then applied as a coating by knife or doctor blades to a tape of cellulose acetate or paper, which is passed between two magnetic poles of the same polarity producing a magnetic field whereby the particles are orientated while the coating is fluid, and then through an oven where the coating is solidified. The binder may be a warmed thermoplastic substance, or a thermosetting material hardened in the oven. The supporting tape may be removed during the process to leave a tape with magnetic particles distributed throughout. The production of rigid sheets and thin bars is mentioned. The ratio between actual values of retentivity in the longitudinal and crosswise directions is usually found to be between 1.7 and 2.

Abstract: 317,426. Beatty, W. E., (Bell Telephone Laboratories, Inc.). May 16, 1928. Television.-In a television receiver comprising a field of light-emitting or light-reflecting elements, the light from each element is caused to persist during the actuation of other elements so as to increase the brightness of the image and reduce the flashing effect. The field of elements may comprise a series of small incandescent lamps or a series of electrostatically controlled reflecting-elements associated with a constant source of light. In the system shown in Fig. 1, the object 10 is scanned by a light pencil as described in Specification 288,238 and the reflected light falls on a photo-electric cell 18 controlling an amplifier 19 connected by line 20 to an amplifier 23 at the receiving station. The potential across a resistance 40 is connected by a distributor 24 successively to a field of reflecting elements 27, each element being similar to a goldleaf electroscope. Each element comprises a fixed plate 33 and a movable plate 34 adapted to reflect more or less light from a fixed source 38. In a further receiving system (Fig. 2, not shown), the potentials across the resistance 40 are connected by a distributor' to condensers in the grid circuits of amplifiers, the plate circuits of which contain small incandescent lamps. The charge on each condenser and the resulting illumination of the associated lamp is maintained in accordancewith the magnitude of a given image impulse until an impulse of different value corresponding to the same elementary area is received. Specification 311,075 also is referred to. Peference has been directed by the Comptroller to Specification 321,194.

An assembly comprises a series of axially stacked sections constituting the stages of a pump, compressor, turbine or the like and a number of flat double-ended tie bars which extend parallel to the longitudinal axis of the assembly with their flat faces substantially tangential to an arc about the axis, the heads of the tie bars, being engaged respectively behind oppositely facing faces of the respective first and last section of the series for maintaining the assembled sections in axially-compressed stacked relationship. An outer casing 4, Fig. 1, of a pump 2 contains an inner assembly which comprises nested concentric sections 14 positioned between end sections 16, 18, and diffusers 22 bolted to the sections. The sections 14, 16, 18 are clamped together by flat oblong steel tie bars 24 provided with heads 26 having shoulders 28. As shown in Fig. 2 the shoulders 28 abut the face 32 of a flange 29 on the end section 18 and a face 32<SP>1</SP> of a flange on the end section 16. The flanges are provided with channels 30, 30<SP>1</SP> which are wider than the tie bars 24. The length L 1  of the tie bars 24 is made less than the distance L 2  between the faces 32, 321, so that the tie bars have to be thermally expanded, by heating to 300‹F. or more, by an amount E before fitting. Thus, on contraction, the tie bars are put in tension and thereby hold the sections 14, 16, 18 -together. The length L 1  is determined by the clamping force required taking account of the length L c , which is the length to which the sections 14, 16, 18 are compressed by the differential pressure between the inlet 6 and the outlet 8 of the pump.
