Title: Temporary grate cover for paint spray booth areas
Inventor: VINICOMBE GERALD K
IPC: B05B15/12
Filed: 1988-05-25
Granted: 1992-06-23
Abstract: TEMPORARY GRATE COVER FOR PAINT SPRAY BOOTH AREAS            ABSTRACT OF THE DISCLOSURE A cover fox paint spray area grates, including grates of the kind having perimeter blades bounding the perimeter of the grate, plural grate blades running in spaced parallel direction along one dimension of the grate and plural grate cross members extending transverse to the grate blades.  The cover is arranged for shielding the grate blades and grate cross members from paint particles entrained in air drawn down through the grate and for facilitating installation of the cover on the grate without substantially inhibiting air flow down through the grate. The cover comprises a lightweight plastic one piece member having (1) a top wall comprising perimeter portions integral with plural length and width cross portions bounding a plurality of openings substantially coextensive with corresponding openings in the grate to be covered, and (2)  skirts depending into the openings from the perimeter portions, length cross portions and width cross portions. Parts of the skirts adjacent said top wall are positioned close to the top of the grate blades and grate cross members.  A pair of the skirts flank each grate blade and cross member.  Each pair of flanking skirts is downwardly divergent so the space between the bottom edges of such pair of skirts is wider than the space between the top edges of the skirts. The skirts bounding each opening define a steep funnel shape such that the opening has a somewhat larger area at the top than at the bottom thereof. The skirts in each opening are connected at the corners thereof such that the skirts form a continuous perimeter wall for such opening.

Title: Fast frame and phase synchronization apparatus
Inventor: SZECHENYI KALMAN
IPC: H04J3/06
Filed: 1988-06-03
Granted: 1992-04-28
Abstract: Abstract The received "unique word" contains both the frame clock and the character clock. On the transmission path, the unique word is distorted in a particular manner.  If this distorted unique word is sampled with a phase-error-containing sampling clock, the phase error can be determined from the sample values.  During the distortion on the transmission path, however, the characters preceding and following the unique word cause preoscillations and postoscillations, which are superimposed on, and complicate the evaluation of, the unique word. In the prior art, such preoscillations and postoscillations are taken into account by averaging over several frames.  According to the fundamental idea of the invention, the values of the preoscillations and postoscillations at the sampling instants are calculated and subtracted as correction values from the measured sample values, so that only the influence of the distorted unique word remains.          Usable control information for adjusting the phase of the sampling clock is thus derived already from the first detected unique word.          Advantageously, however, quantities derived from the sample values rather than the sample values themselves are corrected by derived correction values.  The values of the preoscillations and postoscillations are derived from the regenerated characters by means of the transmission coefficients of the transmission path.          The transmission coefficients are either preset or derived from the equalization coefficients of an adaptive equalizer.

Abstract: For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt. The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C). Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91) (for gas or fluidised powder). Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25). Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91). Wire is fed along passage (B) to the melt: when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt.A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.
