Abstract: NODULE COLLECTOR     Abstract of the Disclosure A nodule collector for deep sea mining includes an outer sledge and an inner sledge disposed in and connected to the outer sledge for trailing movement therewith.  The inner sledge is provided with a transversely extending cutting blade, a plurality of jet nozzles arranged along the cutting blade, and a longitu-dinally oriented duct.  Then the collector travels across the seafloor, the cutting blade cuts into the seafloor and rises it thereover.  The water jet from the nozzles impinges upon the sumit of the risen seafloor so that nodules and sediments at the sumit are carried away by the jet water and introduced through the duct into a collecting chamber provided in the outer sledge.  The collecting chamber has a special design to prevent entrance of undesirably large sized nodules thereinto and residence of undesirably small sized nodules and sediments therein.  The nodules collected in the collecting chamber are successively transported up to the mining ship for recovery.

Abstract: SPECIFICATION          Inventor: Otto Fahl TITLE                   Combination Engine or for short: Coengine ABSTRACT     New internal-combustion engine combining a double-acting piston, or pistons, with valved two-stroke function, and having a fuel gasifier supplying hot, high-pressure gaseous fuel by means of a special safety metering-valve system into the cylinders for precise and complete combustion at all loads and speeds. In this engine system each stroke is a power stroke and all mass forces are compensated by gas pressure, thus reducing greatly friction. Piston faces and cylinder heads have insulation layers, leaving more work for the piston and a special pulsed exhaust turbine which therefore can deliver additional work besides driving the compressor. Supercharging ability and a special overcharging system, which can enlarge the combustion space automatically, increase greatly the maximum power output without affecting adversely the high overall thermal efficiency at low power. This engine is therefore well suited for car and truck engines and for heat pump applications with total heat recovery.

Abstract: Abstract of the Disclosure In a boiler or an industrial furnace, a temperature detecting sensor is mounted at the heat absorbing side of a heat pipe of a waste heat recovery device which is disposed in part of the path of exhaust gas.  With an output signal of the temperature detecting sensor, a flow rate control valve is controlled, and a liquid discharging shield is utilized to maintain the flow rate of the liquid to be supplied in correspondence with the flow rate of the liquid to be discharged.  The effective area of the heat pipes coming in contact with the liquid is varied to maintain the temperature at a heat absorbing side higher than the dew point of sulfur oxide, thus preventing the heat pipes from corrosion, exhaust ducts and so on, and allowing heat absorbing operation to be performed in accordance with the exhaust gas discharge temperature.

Abstract: Inventors:    Theron C. Moss, Richard Mullen, Earl Boring, Jerry Hjellum, Alexander Christisen Title:        "Duster Head And Method Of Making Same"     ABSTRACT OF THE DISCLOSURE   A duster head characterized by a central sleeve portion made from a strip of open mesh backing material, and a plurality of spaced apart longitudinally extending rows of yarn fringe material stitched thereto. To make the duster head, initially two inside rows of the fringe material are stitched to one side of a flat strip of the mesh backing in spaced relation from each other and from the edges of the backing before the backing is formed into the desired cylindrical shape. Both inside rows may extend almost the entire length of the backing material, terminating a short distance from each end thereof. However, preferably one of the inside rows is continued to the adjacent side edge of the backing near the upper end thereof to ensure more complete coverage of the backing by the fringe material in that region. The bottom raw edge of the backing is then serged to give it added strength. Next the mesh backing is folded along the middle intermediate the two inside rows of fringe material and back against itself along the entire length thereof and stitched together along the free edges and across one end to form such central sleeve portion closed at such one end and open at the other end. Then two outside rows of fringe material are stitched to the mesh backing on opposite sides thereof, one along the fold on one side of the mesh backing, and the other along the stitched edges on the opposite side of the mesh backing. The outside row of fringe material on the side opposite the inside row which is continued to the adjacent side edge of the backing is also desirably continued across the closed end of the central sleeve portion. A strip of fabric tape may also be stitched to the central sleeve portion along with one of the outside rows of fringe material adjacent the open end of the central sleeve portion to facilitate tying of the duster head to mop handle.

Abstract: ABSTRACT OF THE DISCLOSURE This invention provides a process for preparing 2-(3-aryl-5-isoxazol)benzoyl halide having the formula wherein X and Y are independently selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, halo-lower-alkyl, phenoxyphenyl and cyano and wherein X1 is a chloro, bromo, fluoro or iodo; which comprises treating 3'-(aryl)-spirocisobenzofuran-l(3H)5'(4'H)-isoxazol] 3-one having the formula wherein X and Y are as previously defined, with an acid halide and water. The compounds obtained are effective as plant growth regulants.

Abstract: TRIANGLE AND PYRAMID SIGNAL   TRANSFORMS AND APPARATUS     ABSTRACT OF THE DISCLOSURE            Transform techniques for transforming numerical signal data into a transform domain and subsequent reconstruction, for purposes such as compression (bandwidth reduction) for communication or storage.  The subject transforms involve several defined basis functions which operate on input data points.  The basis functions of the invention are essentially weighting functions such that terms and coefficients (in the transform domain) calculated in accordance with the basis functions are each a particularly weighted average of the values of a selected consecutive plurality of input data points.  An important basis function is a triangular weighting function. Successive terms and coefficients generated in accordance with each of the defined basis functions are calculated from successive consecutive pluralities of the input data points, with overlap of input data points depending on the particular basis function.  The transforms are organized into a plurality of bands or levels N.          Band N is the highest, and Band 1 the lowest.  The bands or levels are significant for two different reasons: (1) Coefficients are output from the transform process for each band; and (2) In the preferred fast calculation methods the bands represent successive stages of calculation.  For forward transformation, calculation begins with the highest band, Band N, and works down.  For inverse transformation (reconstruction), calculation begins with the lowest band, Band 1 and works up.  Results of processing in each band are then - i -employed as inputs for processing in the next lower band until the last band is reached.  Many of the calculated coefficients have zero values, and there is also disclosed an efficient coding technique which permits the transmission of only the non-zero coefficients.                             - ii -
