Abstract: TITLE OF THE INVENTION Data compression process ABSTRACT OF THE DISCLOSURE     In a process for compressing redundant sequences of serial data elements divided into sequence components each having any number of data elements and a closing character, the first and second elements of a sequence are combined to form a first pair which is stored with its code designation in a group list, That code designation and the third element form a second pair which is also stored with its code designation. That code designation and the following element form a further pair which receives a code designation, and so forth, until the closing character which, with the code designation of the preceding pair, forms a last pair which is again stored with a code. For second and subsequent sequences, the above steps are repeated, with checking for identity between the first pair of the second sequence component and the first pair of the first or one of the further components. If no identity, procedure is as with the first sequence, while if there is identity, the code designation of the first pair is combined with the third element and a check is again made for identity between the further pair of this sequence and the further pair of the first or a further component sequence. If there is identity, the code designation of the further pair is combined with the following element, and so on, to the end of identity between the pairs.  The code designation of the last identical pair is stored in the list, and further elements are then processed as required. In a compressed data sequence list, each component sequence is identified by the code designation of its last pair. The compressed sequence is decompressed by calling up the first code designation of the compressed list, checking whether the first member of the pair is code designation or element; if an element, output of the pair, and repeat the procedure for all subsequent code designations, if a code designation, checking is repeated for the pair denoted by the code designation, until reaching an initial group having an element as first member, followed by output of the pair and the second member of all previously processed pairs. The procedure is then repeated for all subsequent code designations.

Abstract: DIRECT SUCTION RADIAL COMPRESSOR           ABSTRACT OF THE DISCLOSURE    A direct suction radial compressor having a crankcase therein dividing the compressor into an upper chamber and a lower chamber sealed one from the other, and suction inlet tubing extending through the top portion of the upper chamber for delivering refrigerant to the compressor.  A suction chamber is disposed in the crankcase and sealed from the upper chamber and in communication with the suction inlet tubing, and a plurality of radially disposed cylinders are disposed in the crankcase.  Positioned between the suction inlet and the cylinders is a centrifuging assembly that separates liquid refrigerant and oil from gaseous refrigerant, and returns the liquids through a unique network of passageways to an oil sump in the lower chamber.  The centrifuging assembly is constructed so that the liquid refrigerant and oil are collected in a chamber having a pressure greater than the pressure in the lower chamber, thereby creating a pressure differential between the liquid containing chamber and oil sump in the lower chamber to force the collected liquids through a plurality of passageways communicating between the liquid collecting chamber and the lower chamber.  The gaseous refrigerant is then delivered to a four cylinder scotch-yoke arrangement for compression and discharge to an external refrigerant cooler for cooling the compressed gas.  The cooled gaseous refrigerant is then delivered to the upper chamber for cooling cylinder heads and ultimate discharge from the compressor.  An oil pump assembly in the bottom of the lower chamber pumps the collected oil out of the compressor and through an oil cooler to cool the oil. The cooled oil is then returned to the oil pump assembly for delivery throughout the compressor to lubricate and cool components therein.

Abstract: Abstract of the Disclosure The bottleneck of interfacing manual keyboards with high capacity data processing systems to rapidly enter a large number data input characters and processing instructions is resolved to use fewer keys without compromise on the rapidity of data entry.  Thus, data input of either characters or processing instructions is entered in response to a single manual actuation stroke of keyboard keyswitches selected either one at a time or concurrently two or more at a time by a single finger on one hand.  Thus, numeric calculators can with only nine keyswitches process all ten decimal digits plus a variety of processing instructions.  Full alphanumeric data input can be handled with as few as twelve keyswitches.  In this mode of operation fewer keys are needed and there is no delay in entry of data.  Also the invention provides a layout pattern for touch entry of data with one hand with contoured finger homing positions that sense the right keyswitches and reduce entry errors.  A set of side-by-side keys in a single field arranged for selection of each entry by a single finger is provided to improve accuracy of entries by avoiding mental choices and permitting "mechanical" entry of unmemorized new data.
