Abstract: ABSTRACT OF THE DISCLOSURE         A sandblasting machine which includes a container for the sand, the bottom end of which is in communication with a sand flow-regulating valve, in turn communicating with a mixing chamber for the compressed air and sand.          The outlet of said mixing chamber consists of the inner end of a hose serving to feed the air-sand mixture to the sandblasting nozzle.  This inner end of the hose forms a valve seat, which, in conjunction with a ball member, forms a shut-off valve for the sand and air mixture.  This shut-off valve is operated by a pneumatic cylinder remotely controlled at the sandblasting nozzle.  The inner end of the hose may easily be periodically cut when the abrasive action of the sand wears it out.  As an alternative, the valve seat can be formed by a separate hose suction which is replaced when worn out.

Abstract: ABSTRACT OF THE DISCLOSURE        An STV system commonly transmits scrambled television signals which include encoded data reflecting subscriber address, authorization and program code information.  In some STV systems the subscriber installation characteristically comprises a non-addressable converter for converting a transmitted RF signal to an output signal having the frequency of standard VHF television signal.  The invention is addressed to an addressable adapter which responds to the output signal of the converter to render the subscriber installation addressable.  To this end, the adapter comprises tuning means, data retrieval means and an addressable data processor for deriving, among other information, a decode enable signal.  The decode enable signal is instrumental in deriving an unscrambled television signal from the converter output signal.

Abstract: MOVABLE PARTITION BASE ATTACHMENT                 ABSTRACT      A base trim attachment assembly is provided for movable partitions comprising retainer clips having formed barbs which are installed into gypsum panels by pressing the barbs into the panels, and having means for receiving a nail which is driven on a downward angle into the panels. The nails prevent outward movement of the clips and the barbs restrict any upward movement which would normally permit loosening of the nails. After the clips are installed, the base is slipped down over the clips until it snaps in place.  The present structure permits a very thin base which matches existing moveable partition components.

Abstract: IMPROVEMENTS IN CENTRIFUGAL PELLETIZING SYSTEMS                 ABSTRACT OF THE DISCLOSURE             Uniform pellets of thermoplastic material are formed by centrifugally expressing strands of heated ma-terial from orifices on the rim of a hollow rotor and severing the strands with a linearly moving endless blade at a selected radial distance from the rim.  The severed pellets pass in a tangential path through a cooling spray at the entrance to a pellet outlet duct.  The severing blade is mounted on a bracket for movement to and from the severing position and for adjustment radially and circumferentially of the rotor axis.  Two blade assemblies are employed alternately so that blade replacement may be accomplished without interrupting operation.  Downstream from the outlet duct an auxiliary knife-gate is employed adjacent a scrap duct and is movable from a severing posi-tion to a scrap duct closing position.

Abstract: ABSTRACT OF THE DISCLOSURE           An air  inlet valve subassembly for use on a particle fuel burning furnace includes a manifold tube and  a  hollow  spout  mounted  to  an  outer  end  of  the manifold tube.  The spout has an outer rim defining a valve opening and the manifold tube is adapted to be mounted at  its  inner end to the furnace to provide a passageway for communicating air from the valve opening into the furnace. A valve flap is mounted adjacent to the spout for pivotal movement toward and away from the spout between closed and open positions in which the manifold tube passageway is closed and opened to  the communication of air. For sealing the valve opening, a generally  planar,  resiliently  flexible  disk  with  an annular  ring  of  gasket  material  adhered  thereon  is provided. The disk, preferably made of stainless steel material, is removably mounted to the valve flap at the respective centers thereof with its outer side facing toward the flap and its  inner  side facing toward the spout rim. The gasket material ring is affixed on the inner side of the disk and is capable of contacting the spout rim for providing an air seal between the disk and the  spout  rim when  the  valve  flap is at  its closed position. At least one wedge-shaped shim is insertable between the valve flap and the outer side of the planar disk to deflect the disk periphery and cause matching of the  gasket  material  contour  with  the contour of the spout rim. An actuator is linked to the valve flap and is operable to cause movement of the flap between its closed and opened positions.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of assembly of at least two ceramic components each having at least one flat surface, as applicable in particular to microwave equipment and encapsulation modules for microwave semiconductors.          The starting components are made of ceramic material which has been pre-fired, or in other words heated to about 1500°C, and are therefore rigid.  The components are no longer joined together by means of a glass paste or a brazed joint between metallized parts but are heated to over 1700°C.  The impurities which are present in the ceramic material in a proportion of 1 to 10 % serve as a flux and produce an autogenous weld between the two components.  Prior to assembly, the ceramic components can be provided with metallizations such as electric tracks on condition that these metallizations are refractory.

Abstract: ABSTRACT      BLOWING HEAD FOR MAKING TUBULAR PLASTIC FILMS          In a blowing head for making tubular films from thermoplastic material, a lateral inlet for supplying molten material opens into a first annular passage having an upper boundary wall, which extends in a plane which is substantially radial with respect to the blowing head.  A second annular passage is provided, which is concentric to the first annular passage and leads to a die orifice, from which the tubular film is extruded.  The said second annular passage is separated from the first annular passage by a tubular partition, which has a flow guiding surface, which adjoins both annular passages.  The axial length of said tubular insert, measured from the upper boundary wall to the flow guiding surface, decreases from the inner end of the inlet to the diametrically opposite line of confluence of the streams of molten material diverging from the inlet in such a manner that all flow paths for the molten material flowing from the inlet to the die orifice are substantially equal in length.   In one aspect of the invention, the film blowing head is formed with concentric axial passages for supplying and withdrawing inflating and cooling air and one or each of the inner and outer walls defining the second annular passage is formed between the line of confluence of the streams of molten material and the die orifice with coolant conducting bores, which are connected to coolant supply and withdrawing lines.  In a second aspect of the invention, a heating cuff extends in heat transfer relation to one or each of the inner and outer walls which define the second annular passages with the exception of the region that extends axially from the line of confluence to the die orifice.  Both aspects of the invention may be combined.
