Title: Improvements in and relating to a process and apparatus for the manufacture of lamelliform metal powder and particularly that having a lustre
IPC: B22F9/04
Filed: 1923-09-12
Abstract: 204,055. Hartstoff-Metall Akt.-Ges. (Hametag), (Assignees of Podszus, E.). Sept. 12, 1922, [Convention date]. Bronzing and the like.-Metallic powders are ground to a flat form by a process involving apparatus which is adapted to act on small. grains of metal to flatten them out, and at the same time to give them a lustre. The grinding- tools for acting on the metal powders are formed with resilient surfaces preferably of hard rubber or galalith, and preferably electrolytically coated with a metallic deposit of iron. The grinding- tcols are pressed by gravity or spring-pressure, and may be in the form of rollers or balls. The surfaces of the grinding-tools are adapted to touch without forming intermediate spaces to enable the flattening of all particles of the powder to the required extent. A small quantity of oil mav be added to the powder to give it a lustre, and the grinding operation may take place in a mill filled with gas or liquid. As shown in Fig. 3, the powder is ground in a rotary ball or like mill 5 having a wavy cross-section as shown, the inside of the casing being fitted with a fixed bar 6 on which balls or rollers 8 are mounted by springs 7. A rotary fan 10 causes a whirling of the air and a stirring of the powder. The mill 5 is partially filled with metal powder, excess being avoided. In a modified form of mill, a rotary casing 11 with vanes 13 fixed to it, or a fixed casing 11 with rotary vanes 13, is used in connection with a series of balls which are mixed in with the powder. The vanes in turn raise a mixture of balls and powder, and the balls finally fall off on to the powder and flatten it out. Good results are obtained by using 15,000 steel balls of from 3 to 5 millimetres diameter, to one kilogramme of metal powder. Specification 183,134, [Class 59, Grinding, crushing, &c.], is referred to.

Title: Film scanning device
IPC: H04N3/38
Filed: 1952-09-19
Abstract: 717,559. Television. WESTERN ELECTRIC CO., Inc. Sept. 19, 1952 [Oct. 12, 1951], No. 23573/52. Class 40 (3) " In a "flying-spot" scanning device for kinema film fight from the "flying-spot" tube screen passes over two optical paths to a photosensitive device the first path including the film and the second part not including the film and means are provided for separating from the electrical output of the photo-sensitive device that portion due to light traversing the second path and for controlling the intensity of the scanning light beam in accordance with this portion. The invention is described in connection with the scanning of continuous moving film and has for its object to compensate for the variation in the light available at the film due to cyclic variations in the efficiency of the optical path caused by rotating reflecting surfaces. As shown in Figs. 1 and 2, one optical path is defined between the " flying- spot" scanner 18 and the photo-electric cell 20 by the plane mirror 17, rotating compensator 14 and film 13 and a second optical is defined by a plane mirror 21, the elements 17, 14, and a clear portion 27 of the film gate. The mirror 21 is so arranged that light traverses the latter path only for a short interval at the end of each line scan on the screen of tube 18 so that the signal output from photo-electric cell 20 consists of lines of vision signals 101 (Fig. 3), corresponding to the picture information of each film frame separated by signals 102 the amplitudes of which are indicative of the light intensity at the film. These latter signals are separated from the former signals by means of a circuit 23 (Fig. 3) including a sampling arrangement 33 which samples and holds the signals 102 for a period control'ed by "opening" and "clearing" pulses from circuits 34 and 35 respectively under the control of line synchronizing signals. The output from 33 which after smoothing in amplifier 36, approximates to a D.C. vo'tage, is then applied to the intensity control electrode of tube 18 to control the electron beam thereof in accordance with the variation in light intensity at the film gate. Since the signals 102 appear partly during the periods of the normal blanking and synchronizing pulses of tube 18 the latter are delayed by an amount sufficient to permit generation of signals 102 by means of a delay device 37A. Specification 681,058 is referred to.

Filed: 1947-08-27
Abstract: 645,190. Television. PHILCO CORPORATION. Aug. 27, 1947, No. 23698. Convention date, Sept. 7, 1946. [Class 40 (iii)] A visible index-marking, the position of which, in a reproduced television picture, may be varied at the will of an operator, is produced by means which when brought into cooperative relationship with a selected region of the television camera scanning waveform, as reproduced on a monitor cathode-ray tube, generates an electrical signal which is combined with the camera video signal. In the arrangement shown in Fig. 1 the video output of a television camera 3 is reproduced on a monitor tube 7 and a selected region on the screen 15 of the tube is indicated by means of a probe electrode 12 which, by capacitative action, picks up an impulse charge from the electron beam in tube 7 as it scans the selected region, the impulse thus generated being amplified and shaped in 17 and 18 respectively and, after further amplification in a paraphase amplifier 19, combined with the video output from camera 3 in unit 5 for modulation on to the transmitter carrier so that, in the picture reproduced at a remote receiver, a visible index appears in a position corresponding to the position of probe 12 relative to the monitor screen, the index being either white or black, depending on the output polarity of amplifier 19 which is selected by switch 22. To ensure that an index is always produced, the tube 7 is operated at a reduced contrast ratio so that the beam is never cut-off (i.e. black is reproduced as grey). Alternatively the tube 7 may be operated with no video modulation so that the scanning raster of the camera only is reproduced, the position of the generated index being observed in a further monitor tube (not shown) which is supplied with the combined video output from unit 5. Details of the construction of the probe electrode 12 are described with reference to Fig. 2 (not shown).

The two parts are secured together by the engagement of a tongue 16 on the part 10 with a guide 17 on the part 11, the guide 17 having a depression 18 which registers with one of a number of depressions 19 on the tongue 16 to retain the parts in their adjusted position. Alternatively the retaining means may comprise a set screw or a friction spring. A disinfecting medium, such as a sheet of paper impregnated with disinfectant, may be arranged on the inside of the protector. Reference has been directed by the Comptroller to Specifications 17570/93 and 111.781.

Drawings to Specification. [Class 100 (iv)] A transfer device comprises a sheet of paper impregnated with an oil and pigment ink and coated on one side with a metallic powder. The paper, preferably unsized uncalendered " water-leaf " paper, is either soaked in the ink, which may contain aluminium or bronze powder, or the powder is applied after inking. In either case the powder lies on the surface and acts to retard the transference of ink to the duplicate paper. The obverse side of the paper may be coated with pyroxylin lacquer to prevent marking of the back of the original sheet. The transfer material may be used in rectangular sheets, or in discs of the type described in Specification 403,011, which are rotatably mounted between the record sheets. The capillary nature of the paper transfers ink from the unused portions of the disc to the circumference, which is the only part used, the lacquer stiffens the disc, and the powder coating enables it to turn easily between the sheets. The lacquered side of the sheet may also be dusted with powder.
