Abstract: 1377447 Copying magnetic recordings RCA CORPORATION 24 Feb 1972 [2 March 1971] 8504/72 Heading G5R  A pre-recorded magnetic medium such as a tape 12 is copied on to an unrecorded magnetic medium such as a drum 26 by placing the particle layers 12a, 32 of each medium in intimate contact and heating the particles of the unrecorded layer 32 to their Curie point by means of a focused beam 36 of radiant energy, such as a laser beam, the size of the focused spot being of the same order as the largest particles of layer 32, the spot being deflected to scan the unrecorded layer 32. Layer 32 becomes magnetized by the field of recorded layer 12a upon cooling. The Curie point of the unrecorded medium should be lower than that of the recorded medium. As shown, the recorded tape 12 is driven in contact with the drum 26, to which the recording is transferred and then recorded therefrom on to a second tape 42 by an identical process. The recording is then erased from the drum 26 at 56. The spot scanning direction is transverse to the direction of motion. The substrates 30, 42b of the unrecorded media are transparent to the radiation, e.g. glass or quartz for 30, oriented polyethylene terephthalate for 42b.

Abstract: 579,273. Cathode ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 22, 1942, No. 8555. Convention date, June 21, 1941. [Class 39 (i)] In apparatus for television transmission comprising a tube having an electron gun at one end and a light-sensitive target electrode 22 at the other end, and having deflecting means 10, 11 between them and wherein an electron decelerating field is produced in the tube so that electrons approach the target electrode at substantially zero velocity, the target electrode presents a concave surface to the gun, the radius of curvature of which is less than the distance between the target electrode and the centre of deflection 12 of the beam and electrodes 8, 15, 16 are provided adjacent to the target electrode at such potentials that the equipotential field gradient near the target has the same radius of curvature as the target so that the beam is caused to follow trajectories substantially radially incident on to said target for all degrees of deflection of the beam. It is shown by dimensioned field diagrams that this arrangement avoids non-uniformity of beam incidence over the target which would otherwise result in so-called " creeping " distortion. Electrodes 15, 16 may be metallic coatings on the inside of the envelope, as shown, or may be metallic grids transverse to the axis of the tube. The optical objective 24 which throws the image upon the curved target may be overcorrected for curvature of field so that the image coincides with the target at every point.

Filed: 1949-03-30
Abstract: 659,117. Conveyers. BAKER PERKINS, Ltd. March 30, 1949, No. 8602. Convention date, Oct. 22, 1948. [Class 78 (i)] [Also in Group XL (b)] Articles conveyed on a conveyer are removed by magnetic means which pull the articles along the surface, the removal means being stopped automatically in the event that articles are in a position to interfere with the operation of such means. Articles such as pans A are transferred from a proofer conveyer 2 to a cross conveyer 1 over an apron 4 by means of a magnetized beam 6 which contacts the leading edge while a bar 25 drops behind and assists in the transfer. Electromagnets 7 are mounted in the transverse beam 6 secured to a carriage 8, connected to the driven chain 15 and having wheels 9 running on side flanges of the frame. The pusher bar 25 is secured to a transverse shaft 26 with wheels 27 engaging the flange and has links 28 connected to the carriage 8 and of such length that the bar reciprocates on the lower run of the chains. An upstanding flag 41 is also linked to the bar 25. The bar is raised out of contact with the pans by means of cams 29 at the transfer end and by pivoted arms 30 and adjustable arms 35 at the other end. Four electric circuits control the magnetization and movement of the bar 6 and the cross and proofer conveyers respectively, the circuits being operated by cams UC, MC, CC, PC on a shaft 48 driven from the conveyer shaft. The cams operate switches UC1, MC1, CC1, PC1. Each circuit includes a relay with a switch with byepasses and push-button control. Photo-electric control comprises eyes CI, PI, which cooperate with cams CC and PC which operate to close the circuit and sound air alarm if the pans do not clear the proofer conveyer 2 before being conveyed by the cross conveyer 1 and if the pans move too far along the proofer conveyer before the magnetic bar 6 descends to contact them. A further pair of eyes SI are operated when the bar falls on top instead of in front of a pan the beam being intercepted by the flag 41 to break the circuit. A timing device is included in the bar circuit to close a switch to operate the bar which conveys pans to the cross conveyer. The wheels 9 contact a bar 47 to close a switch C<2> to start the cross conveyers and to stop it members 46 on the conveyer operate a switch C<1>. The beam of eyes PI are cut by the bar 6 as it is lowered into a position to contact a pan where the bar stops and the timer closes. The timer holds for several seconds to allow the conveyer 2 to move pans close to the bar 6.
