Abstract: ABSTRACT:           A system for the reproduction of signals stored in diagonal tracks (S1,S2,S3,S4,S5,S6,S7,....) on a mag-netic tape (1) incorporates a drum-shaped scanning device (2) with at least two magnetic heads (K1,K2), each mounted on an electro-mechanical adjusting device (A1,A2), of which magnetic heads only one is in scanning contact with the magnetic tape during first scanning intervals (T1) while during second scanning intervals both are in scanning contact with the magnetic tape (1), which is partly wound round the scanning device (2).  For genera-tion of the adjustment signals to be applied to the adjust-ing devices (A1,A2) for the purpose of guiding the mag-netic heads (K1,K2) along the tracks-signals containing a measurement of the deviations of the magnetic heads from the track - an adjustment-signal generating circuit (14) is provided, to which the signals reproduced by the two magnetic heads simultaneously in scanning contact are taken in time-division multiplex form during the second scanning interval (T2), signals generated in the adjustment-signal generating circuit (14) and corresponding to the adjust-ment signals for the two adjustment devices (A1,A2) of these magnetic heads being taken on a TDM basis via a second switching device (40) controlled in a similar man-ner to the first switching device (29) to storage cir-cuits (36,37) connected at the inputs to these adjustment devices.

Abstract: SHELF STRUCTURE FOR INDIVIDUALLY SUPPORTING     A PLURALITY OF CYLINDRICAL ARTICLES                ABSTRACT OF THE DISCLOSURE          A shelf structure for individually supporting a plurality of generally cylindrical articles comprises a plurality of generally parallel, congruent, undulating principal wires, each defining a plurality of upper vertices and a plurality of lower vertices.  A plurality of pairs of mutually parallel linear support wires extend perpendicularly to the principal wires.  Each pair of support wires is joined to the upper surfaces of the principal wires with one wire in each pair spaced to one side of one lower vertex and the other wire of each pair spaced to the other side of the lower vertex.  Every such pair of support wires is thus adapted to support one article with the axis thereof extending parallel to the support wires.  Additionally, the wires in each pair are spaced by a distance small enough to prevent a typical article supported thereon from contacting the undulating wires and adjacent pairs of support wires are spaced by a distance sufficient to prevent typical articles supported thereon from contacting each other.

Abstract: ABSTRACT OF TOE DISCLOSURE         The cavity of a foundry blow box for blowing sand into molds is formed by a tube extending downwardly but terminating slightly above the blow plate forming the bottom of the blow box, thus forming a peripheral gap which is essentially the only aperture for the admission of fluidizing air.  The air tends to blow sand contacting the blow plate directly through its exit into the mold, although fluidizing the remaining said through the cavity.          Preferably, especially if quick-setting sand is used, a plunger snugly fitting the tube moves through it to its bottom so that air from the gap scours the plunger and blow plate, blowing out all sand.  As the mold is lowered, a purge pan is substituted to receive any sand beyond the mold capacity.  The rapid mixer is improved, using successive notched impeller blades that selectively impact the two streams of non-curing sand to be mixed.  The gap is wider than the sand particles.  The plunger is the subject of a prior application of the inventor, used then with a finely aperture wall.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus are provided for assembling innerspring constructions from rows of pocketed coil springs.          The apparatus includes a surface for supporting the rows and a pressure plate which comprises them slightly while holding them in straight lines.  After each row is positioned between the surface and the plate, a hot melt applicator is passed thereby and deposits a selected amount of bonding material to the fabric encasing each coil spring.  New rows are pushed into contact with the treated rows and each displaces them by about one coil spring diameter.  A plurality of rows are maintained under compression at all times to insure they remain in alignment with adequate frictional contact therebetween.  A bar having markings corresponding to each pocketed coil spring within a row is mounted to the apparatus.  A beam switch or the like is provided for detecting these markings and actuating the applicator at a selected time as it passes each spring.

Title: Superconductor switch - including superconductor coil having magnetic shielding of superconductive material
IPC: H03K17/92

Abstract: A switch comprising a superconductor coil (e.g. Nb) and magnetic shielding which is in the superconductive state when the coil is in its superconductive state under given cooling conditions, the shielding being so constructed and positioned in relation to the coil that lines of force at the magnetic field produced by the coil when conducting a current below a predetermined value are forced to follow extended paths, but the shielding being such that attainment by the current of the predetermined value brings about a reduction in the effectiveness of the magnetic shielding with shortening of the lines of force so that the magnetic field strength of the coil rises switching the whole of the coil rapidly from the superconductive to the normally-conductive state, wherein a layer of thermally insulating material of high dielectric strength pref. plastics foil, is provided on the coil to prevent direct contact between the coil and the coolant thus enabling the coil to heat-up rapidly and improve the switching action.
