Abstract: ABSTRACT         There is provided the combination of a stationary frame, a stationary sun gear on the frame, and a rotary frame pivoted about the axis of the sun gear.  The rotary frame carries three crankshafts at substantially 120° intervals, and for each crankshaft there is provided a cylinder in the rotary frame, and a piston mounted for reciprocation in each cylinder.  Each crankshaft is fixed to rotate with a respective planetary gear and all planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear.  Thus, any point on the pitch circle of a planetary gear describes a cardioid as the planetary gear rotates around the sun gear once. The crankshaft eccentricity is about one-third of the pitch radius of a planetary gear, and each piston has a connecting link to its respective crankshaft.  Fuel metering means, such as a carburettor, are provided for delivering a combustible mixture to the cylinders.  Ignition means are provided to ignite the combustible mixture, and valve means are present for admitting a combustible mixture to each cylinder and exhausting combustion gases therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE           A  method  for  reclosing  a  temporarily opened circuit braker in a manner which assures that generation  of  unwanted  overvoltage  stresses  is avoided during the reclosure process.   An oscillat-ing line voltage typically develops in a shunt-com-pensated line after a circuit breaker connecting the line to a voltage  source  is opened.    When the circuit breaker is reclosed the source voltage and the oscillating voltages must be properly phased to avoid the overstressing problem.   In operation, the polarities of the feed voltage and the oscillating line voltage are detected and the instant when the circuit braker may be reclosed is calculated. The periods TL and TS of the line voltage and the feed voltage are measured.  Also measured is the time .DELTA.T which  elapses  from  a  zero  crossing  of  the  line voltage waveform to a subsequent zero crossing of the  feed voltage waveform  having the  same phase angle as that of the line voltage zero crossing.        The circuit breaker is reclosed upon satisfying the relationship:       where m,   n are natural numbers which are sequen-tially entered in the above equation.

Abstract: Abstract In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and relieves the host of some of the burden of managing disk drive communications. The format has three layers.  A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes.  A second, logical layer is used to address the physical layer and to collect together sectors to form a multiplicity of separately addressable spaces, with each space having a distinct functional utility.  At a third, functional layer the use of data fields in each space is specified.  This layer governs the handling of bad blocks if required, and the use of certain format information.    At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders.  These are logically, rather than physically, defined collections.  A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time.  At the logical layer, the disk is divided into three main areas, each separately addressable.  The first main area is broken down into two sub-areas.  The first sub-area is available to the host computing system for its use; the second sub-area is used for replacement of bad blocks.  The second is for format information.  The third main area is for diagnostics.    Various drive parameters are stored in the disk and are supplied to its controller on command, permitting the controller to adapt thereto.  These include the starting address for each of the various areas, or spaces, of the disk and, for example, its transfer rate, logical addressing structure, etc.

Abstract: ABSTRACT         DATA PROCESSING SYSTEM WITH REORGANIZATION OF                 DISK STORAGE FOR IMPROVED PAGING      In a data processor having a paging system, a list is kept of the disk seek time when a page of information is brought into processor memory from a disk storage device.  (Seek time is the time for moving the disk read-write head radially inward or outward to the next track that is to be accessed.)  The average seek time for the pages in memory is calculated and is compared with a reference value of seek time.  When the average reaches the reference, the pages in memory are reordered on the disk.  This reordering takes place as the pages are bumped from memory in the normal process of paging, and the pages are relocated on the disk tracks in the physical order in which the pages were originally brought into memory.  If approximately the same pages are fetched again in approximately the same sequence, the read-write head of the disk drive will be moved a shorter distance between successive disk accesses with reduced backtracking.  The invention is particularly intended for a data processor of intermediate size that is large enough to use a paging system but small enough to use a disk drive that has an appreciable seek time.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a method for compressing a low tem-perature high density liquid gas, for example, helium.  The method comprises the steps of:  withdrawing and transferring the fluid from a storage receptacle to the accumulator of the first inlet of a two stage compressor; compressing the fluid in the first stage to a pressure intermediate that of the storage receptacle and the final pressure at the point of delivery of the fluid; transferring the pressurized fluid from the first stage to a second stage permitting warming of the fluid during transfer and compressing the fluid to the pressure required at the point of delivery; and heat exchanging and warming the fluid exiting the second stage against ambient atmosphere and discharging the warmed fluid to a point of use.  The prior art methods of compressing usually require a large capacity heat exchanger and a source of heat, together with a compressor con-taining usually 4 or 5 stages and inter and after stage cooling requiring a driver, a cooling source and devices to remove entrained contaminants, namely, oil in the form of vapors used to lubricate the compressor.

Abstract: ABSTRACT OF THE DISCLOSURE         An information recording and reproduction apparatus for recording and reproduction of information in a recording medium having an information recording area divided into a plurality of sectors, in which a defective sector is replaced for recording and a signal for identifying the defective sector is recorded.  Each sector includes a preformatted sector identification section ID and a data field for recording data therein.        A defective sector is replaced by a sector at another position.  When the sector identification section ID and/or data field DF has a defect, a first signal is recorded in addition to the data in the data field DF, followed by writing a second signal overlapped in the sector identification section ID of the same sector which causes an address data read error thereby to attach a defect mark to the defective sector.  By detecting the first signal at the time of recording or reproduction, the sector involved is known to be defective, and at the same time, the data therein is transferred to another (replacement) sector, or a sector is detected where the data is recorded.  A defective sector never fails to be identified by the second signal overwritten in the sector identification section ID.  A defective sector is thus detected in real time at the time of data recording or reproduction, and therefore the defective sector replacing operation is performed in a minimal access time.  Further, the storage capacity has no loss since a defective sector is identified by a signal recorded in the data field section DF.

Abstract: METHOD FOR QUALITY CONTROL OF COUNTING LOGS            Abstract A generalized computer-based system and method for acquisition of nuclear well logging data.  A feature of the present invention is the ability to provide time distribution spectra over the entire interval between source firings, such spectra including both the gamma radiation produced from the inelastic scattering and capture of neutrons from said neutron source.  The spectra so generated may be analyzed and processed to derive parameters indicative of formation and borehole conditions, for example, a parameter sensitivity to borehole geometry and a parameter sensitive to porosity.  Certain parameters may be compared as an indication of  the presence of gas in a fluid filled formation.  Still further, a quantitative measure of the repeatability of the macroscopic thermal neutron absorption capture cross-section may be derived and used to control the weight of the capture cross-section filter.
