Title: Take-up
IPC: D05B49/02
Filed: 1922-01-11
Abstract: 185,697. Fairweather, W., (Singer Manufacturing Co.). Jan. 11, 1922. Multiple-needle machines; governing needle thread.-A thread take-up carried by the needlebar comprises a plate 8 having an L-shaped thread aperture 10, Fig. 3. The thread is engaged by an horizontal portion lOb of the aperture until, in the descent of the plate, the thread contacts with a fixed oblique cage 21 and is pushed off the edge 10<c> into the upwardly inclined portion 10<a> of the aperture. The device is applied to a multiple-needle machine having one lcoper so as to provide that the several needle-thread loops shall be taken-up in pairs as they are cast-off the looper. Fig. 3 shows the application to a two-needle machine. The thread of one needle passes through the slot 10 and the thread of the other needle passes through an eye 9. Both threads pass over guide-arms 25, 26 Fig. 7, and the thread passing through the eye 9 lies above arms 15. In the first part of the descent of the needle-bar, the take-up gives up slack to each thread : then, when the first of the previously-formed loops is being cast off from the looper, the horizontal portion 10<b> of the L- shaped aperture in the take-up plate carries the supply side of the thread to that loop below the level of the arms 25, 26 and the slack of the freed thread-loop is thereby taken up : later, when the second thread-loop is cast-off, the supply side of its thread is carried by the eye 9 between the arms 15 and the slack of the loop is more rapidly taken-up. Shortly after the second loop is cast-off, the inclined edge 21 frees the thread from the edge 10<c>. A slack-thread controller operating on both threads is provided by a spring arm 29 which rests on the threads between the arms 25, 26. The upper limit of movement of the arm 29 is determined by a bridge piece 42 and the lower limit by an adjustable stop 37, Fig. 3. For machines having more than two needles the number of L-shaped apertures is increased and they are arranged to act in turn in conjunction with inclined edges such as 21. Fig. 5 shows a take-up plate for a three-needle machine.

Title: Method for processing video picture
Inventor: THOMAS GRAHAM ALEXANDER
IPC: H04N7/32
Filed: 1991-09-20
Abstract: The appropriate one of a list of possible motion vectors is applied to each region of a video image. An image value for that region is determined for each of four successive fields, for each of the possible motion vectors. The values for these four fields are compared and when the values are substantially the same for a given vector it is assumed that is the vector appropriate to that region. The vectors appropriate to regions of obscured or revealed background can also be assigned by comparing inter-field differences and determining regions where the inter-field differences are high for the central pair and one outer pair and low for the other outer pair of fields. To generate regions corresponding to obscured background only information from the earlier fields is used and to generate regions corresponding to revealed background only information from the later fields are used.

Title: Heat treatng method and apparatus of base material
Inventor: JIYON MAIKERU GURIINUEI
IPC: D06C23/00
Filed: 1984-01-06
Abstract: The invention provides method and apparatus for imparting visual surface effects to a relatively moving, thermally modifiable substrate (12) by application of discrete streams of heated pressurised fluid, e.g. gas, to surface areas of the substrate. The apparatus includes an elongate manifold assembly (30) comprising two gas receiving compartments, (81, 160), each extending across the path of said substrate. Heated gas from the first compartment passes into the second compartment, which is comprised of a series of chambers (162, 166) with an elongate exit slot (115) positioned closely adjacent the substrate surface. The gas is uniformly mixed within the second compartment, and may then be directed from the exit slot onto the substrate as a thin, continuous stream or curtain extending the length of the manifold. By use of blocking streams of relatively cool gas which deflect the dilute selected lateral segments of the heated gas stream in accordance with pattern information after the curtain of heated gas emerges from the exit slot, smaller streams of groups of streams may be formed which squarely impinge on the substrate surface and impart a selected pattern to the substrate, by thermal modification of the surface.
