Abstract: The present invention relates to a centrifugal pump structure which allows easy, sturdy, and reliable mounting of the pump on its bed in several different attitudes. Prior art centrifugal pumps or more precisely the casings of the pumps have two support legs by which the pump is mounted on its bed. This allows mounting the pump in a simple way only in one basic position which almost without exception is with the pressure opening upwards. If it has been necessary to mount the pump with the pressure opening facing to the side, the bed of the pump has been provided with a vertical suspension member on which the pump has been suspended with its legs. This kind of a suspension is not, however, rigid, strong, sturdy or reliable as the pipe line forces exert great stresses on the pump shaft, bearings, etc. The above disadvantages have been eliminated by a mounting system of the present invention according to which the legs (7, 17) of the casing are situated at the opposite side of the pump to that of the pressure opening (6) and on both sides of the longitudinal plane passing through the pump shaft (4) and the pressure opening (6); in which the legs (7, 17) have two planar surfaces (27, 37) for mounting of the pump; and in which there are, on both sides of the pressure connection (6) substantially in the longitudinal plane passing through the shaft (4) of the pump, brackets (8) with planar mounting surfaces (18, 28) for mounting the pump.

Abstract: The invention relates to a process for preparing oxamide by a reaction taking place in a methanol solution between dimethyl oxalate and ammonia. The formed oxamide is separated out from the solution by crystallization, and the formed methanol is recovered from the solution by evaporation. According to the invention the preparation is carried out as a continuous process in which a portion of the mother liquor from the oxamide crystallization step is directed to an evaporator for methanol separation and in which the evaporation residue is combined with the balance of the mother liquor, which is recycled to the reaction step as the solvent into which the dimethyl oxalate and gaseous ammonia are fed. It is possible to use in the process one or more cooled reaction vessels, connected in series, in which the temperature is preferably adjusted to the range 15-45  DEG C, and one or more mixing vessels subsequent in the series to the reaction vessels, the oxamide separating out from the solution by crystallization in these mixing vessels. The feeding in of the ammonia required in the reaction may be suitably divided among the various reaction vessels in order to even out the heat amounts released in the various vessels.

Abstract: A cache memory unit is constructed to have a two-stage pipeline shareable by a plurality of sources which include two independently operated central processing units (CPUs). Apparatus included within the cache memory unit operates to allocate alternate time slots to the two CPUs which offset their operations by a pipeline stage. This permits one pipeline stage of the cache memory unit to perform a directory search for one CPU while the other pipeline stage performs a data buffer read for the other CPU. Each CPU is programmed to use less than all of the time slots allocated to it. Thus, the processing units operate conflict-free while pipeline stages are freed up for processing requests from other sources, such as replacement data from main memory or cache updates.

Conventional surfactants, blowing agents and acidic catalysts are used to prepare the foams. The foams so prepared generally have no tendency to autoxidize when placed in an oven heated to a temperature of 250<o> Centrigrade. The foams so prepared also have enhanced resistance to flame penetration.

Abstract: Video random access memory having a random array and serial buffer is employed to speed the replication of structure state information used in the processing of hierarchical   graphic   data   structures.    Specialized circuitry in the video RAM and associated VRAM sequencer are used to perform a rapid transfer of structure state information from one row of the VRAM (the parent row) to a second VRAM row (the child row).  The VRAM sequencer is modified to perform back to back read data transfer and write data transfer operation in response to a single graphics  processor  command.   The  return  to  previous structure state can be accomplished by readdressing the VRAM row containing the previous structure state.

Granted: 1995-10-03
Abstract: A method and apparatus are provided for producing multiple,  frequency-addressable  beams  (66-80)  employed  in  a satellite   communication   system.    The  beams   (66-80)   are effectively  scanned  over an  area of  the  earth  in  order  to communicatively  interconnect  small  communication  terminals  on the  earth.   Multiple beams  are  formed which  can be  scanned independently of each other in the direction of scanning.  Two or more beam formers (104, 106) are coupled in parallel and feed a single array of antenna elements.   The outputs of the beam formers  (104,  106) are combined in summers  (98) and are then amplified by power amplifiers 38 and applied to excite the array elements (30).  Phase shifters  (92-96) are coupled between the beam formers (104, 106) and the array elements (30) to shift the phase of the beam signals and thereby aim or shift the beams in a direction orthogonal to the scanning direction in order to provide the desired coverage over the earth.
