Abstract: ABSTRACT OF THE DISCLOSURE         Casing hardware, such as float collars and shoes, are used in oil well cementing operations.  Some of the collars and shoes are constructed of a steel casing with a concrete core inside the casing.  The casing structure of the collars and shoes now available places the core under a predominantly shearing force, so that it will fail at relatively low downhole dif-ferential pressures.  The present invention provides a new design for the casing structure, which places the concrete core under a predominantly compressive force, and greatly increases the amount of pressure the core can withstand without failing.

Abstract: APPARATUS AND METHOD FOR ACQUIRING  MULTIPLE GROUPS OF DATA SIGNALS FROM A SYNCHRONOUS LOGIC SYSTEM            Abstract of the Disclosure An apparatus and method which may be used with a logic analyzer are provided for acquiring groups of data words from the circuitry of a sychronous logic system where each group contains a qualified data word together with a predetermined number of unqualified data words which have immediately preceded it.  The apparatus includes a circuit for detecting the quali-fied word and a data storage device having a plurality of separately-addressable storage locations.  Both the qualified data detector and the storage device are logically connected to the synchronous logic circuitry. The apparatus further includes an addressing circuit which responds to the detection of a qualified word and to the presence of data words on the synchronous logic circuitry by producing storage addresses which are pro-vided to the storage device for storing the data word groups in successive storage locations.  In an alter-native embodiment, the addressing means responds to qualified word detection and to the number of data words stored in the storage locations such that each stored group of data words contains a qualified word and a respective number of data words.

Abstract: Abstract ON-THE-FLY DATA COMPRESSION SYSTEM   An   on-the-fly   data   commpression   system   for compressing the data transmitted between a data source and an ultimate utilization device.  The system normally has   two   data   compression  modules   implementing   a conventional  multi-buffering  scheme  and  a  decoder  for reconstructing  the  compressed data  to  its  original format.   The  data  compression  modules  compresses  the data   using   a   word   representation   by   associative processing  buffer  and  a  content  induced  transaction overlap  transmission  protocol  which  results  in  an interleaved transmission of data bits and bit position bits, the latter being indicative of the number of data bits that will be transmitted during the subsequent data transmission.   The decoder  reconstructs  the  compressed data  to  its  original  format  in  response  to  the transmitted data and bit position bits and stores them in a pair of buffers in the sequential order in which they were generated.

Abstract: ABSTRACT      Three-way catalysts containing rhodium, rare earth oxide   and  platinum  and/or  palladium  of   improved durability, when subjected to exhaust gases containing excess oxygen, are formed, when the rhodium is segregated from the rare earth oxide, thereby preventing undesirable interactions between the rhodium and rare earth oxide. The  efficiency  of  the  catalyst  is  optimized when the rhodium has an initial average particle size ranging from about 35 to about 80 .ANG. in diameter.  P-type oxides in intimate contact with ceria are  found to enhance  the catalytic efficiency of platinum containing catalysts.

Abstract: ABSTRACT            "Method for the glow discharge-activated reactive deposition of electrically conductive material from a gas phase."     For the reactive deposition of tubular bodies of electrically conductive material from a flowing gas phase on a tubular substrate (1) a glow discharge 11 is produced between an inner electrode 6 and an outer electrode 2 one of which is constructed so as to be tubular and serves as a substrate.  It is ensured that the electrodes 2, 6 are not short-circuited by growing conductive surface layers so that the glow discharge 11 extinguishes.  Furthermore, the electrically conductive coating on the electrode 6 not functioning as the substrate electrode is interrupted in an insulating manner to limit the glow discharge 11 locally.  For example by a gas barrier the deposit of an electrically conducting deposit on the insulation can be avoided.  The glow discharge 11 is reciprocated during the deposition process. Figure 1.

Abstract: ABSTRACT      A cathode ray display tube has a mild steel envelope part (10) with a tubular copper pump stem (20) sealingly attached thereto by friction welding.  A method of attaching the pump stem involves forming the pump stem initially with a closed end, rotating the pump stem relative to and against the mild steel envelope part and applying pressure to cause friction welding of the pump stem, and thereafter extending the pump stem's bore through its closed end by drilling.  A hole may simultaneously be drilled through the envelope part.  The friction weld provides reliable vacuum-tightness and strength, and the attachment of the pump stem in this manner can be accomplished using automation quickly and inexpensively.

Abstract: ABSTRACT          In an optical shaft encoder for converting rotary motion to an electrical signal, a shaft is rotatably mounted in a base and has a code disk attached thereto.  A light source and photodetector are disposed on opposite sides of the code disk.  The photodetector is covered by a mask which is attached thereto.  The photodetector/mask assembly is loosely inserted into a printed circuit board and a spacer is placed between the code disk and the photodetector/mask assembly to achieve a predetermined air gap.  The photodetector/mask assembly is then radially aligned with the code disk.  After proper placement, the photodetector/mask assembly is soldered in place and the spacer is removed.  This technique allows the optical shaft encoder to be manufactured to precise tolerances without the necessity of precision machining.

Abstract: ABSTRACT            A hose pump     consisting of a hose    , at least one, preferably two pressure rollers       , a support plate and a drive source     . The hose     is placed in a hose receiving track     in the support plate     .          The rollers       are rotatably journalled on a common rotary shaft     ,whose centre      is firmly connected with a drive shaft     , which is perpendicular to the support face     of the support plate     engaging the rollers.       The rollers        act on the hose     in the flow direction of the pump     and alternately determine, in specific angle ranges, the liquid volume flow discharged.          The succeeding roller     cooperates with the hose     in such a manner that the hose is completely closed when the forwardly disposed roller    , as seen in the flow direction, initiates its disengaging movement away from the hose    . During the following opening movement of the forwardly disposed roller     from having closed the hose     completely to letting it be completely open, the succeeding roller     cooperates with the hose so that the hose, in addition to discharging a volume flow corresponding to the normal volume flow of the pump , also discharges an additional volume flow to compen-sate for the loss caused by the opening movement of the forwardly disposed roller    . Then, the volume flow discharged by the pump     is constant per unit of time.          Further, reverse suction in the outlet end of the hose is obviated.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an injection molding system having two heated nozzles mounted in tandem.  The rearward nozzle is considerably longer than the forward nozzle and has a melt bore which is considerably larger in diameter than the melt bore of the forward nozzle,  The smaller forward  nozzle has a backplate secured to its rear end with a thin flanged portion which extends outwardly and rearwardly into bearing contact against a rearward mold core to secure the forward nozzle in position in a well in a forward mold core.  The rear face of the backplate has a seat extending around the melt bore to receive a cylindrical forward portion of a gate insert mounted on the forward end of the rearward nozzle.  Thus thermal expansion of the larger rearward nozzle is taken up by the forward portion of the gate insert sliding in the seat.  The smaller forward nozzle has a portion of the electrical heating element extending into a forwardly extending nose portion which provides sensitive temperature control in the gate area.
