Granted: 1992-05-19
Abstract: ABSTRACT    The invention is a method of performing a plurality of vibratory seismic surveys simultaneously.  A plurality of vibratory  sources  transmit  signals  into  the  earth. Each  vibratory  source  successively  transmits  the  same signal,  except  that  an  offset  phase  of  the  signal  is selectively  shifted  for  successive  transmissions.   The offset phase of the signal transmitted by each vibratory source is selected to enable the signal from each of the vibratory sources to be recovered by data processing.

Title: Multiband radar detector
Inventor: MARTINSON GLEN
IPC: G01S7/02
Filed: 1987-12-23
Granted: 1992-02-11
Abstract: MULTIBAND RADAR DETECTOR          ABSTRACT OF THE DISCLOSURE:          The invention concerns radar detectors which are capable of monitoring at least two frequency bands. A broad band antenna is provided, together with a mixer comprising an anti-parallel  pair  of diodes,  and at least one  local oscillator. The local oscillator frequency is mixed with radar   frequency  from  the  antenna  to   produce   an intermediate  signal  which  is amplified  further  down converted   detected  and  fed  to   signal   processing circuitry  to  actuate an alarm when radar frequency  of interest is detected. The most effective mixing with the RF  input   takes place at twice  the  local  oscillator frequency. By  application of direct current bias to the mixer,  the  most effective mixing with the RF input  is changed to occur at the local oscillator frequency.  The local  oscillator is used to monitor two different radar frequencies  by  application and non-application  of  DC bias to the mixer.  For multiband detectors,  more  than one local oscillator may be used.

Title: Customization by automated resource substitution
Inventor: SOUCIE MARC S
IPC: G06F9/46
Filed: 1988-08-19
Granted: 1991-07-30
Abstract: An object based data processing system including an extensible set of object types and a corresponding set of "object managers" wherein each object manager is a program for operating with the data stored in a corresponding type of object.  The object managers in general support at least a standard set of operations.  Any program can effect performance of these standard operations on objects of any type by making an "invocation" request.  In response to an invocation request, object management services (which are available to all object managers) identifies and invokes an object manager that is suitable for performing the requested operation on the specified type of data.  A mechanism is provided for linking data from one object into another object.  An object catalog includes both information about objects and about links between objects.  Data interchange services are provided for communicating data between objects of different types, using a set of standard data interchange formats.  A matchmaker facility permits two processes that are to cooperate in a data interchange operation identify each other and to identify data formats they have in common.  A facility is provided for managing shared data "resources".          Customized versions of resources can be created and co-exist with standard resources. A resource retrieval function determines whether a customized or a standard resource is to be returned in response to each request for a resource.

Title: Multidirectional exerciser
Inventor: MCGILLIS JOSEPH P
IPC: A63B23/12
Filed: 1988-08-30
Granted: 1993-05-11
Abstract: Abstract of the Disclosure An isokinetic multidirectional exerciser utilizes an articulated boom mounted to a supporting base for pivotal movement relative to the base.          The articulated boom preferably uses two arms which are pivotally connected. Relative movement between the boom arms and the base is individually resisted by fluid devices operatively connected between the members that move relative to one another during use of the exerciser. Each fluid device includes a resistive closed fluid path that is adjustable to vary the range of resistance that will be encountered during such movement. Provision is made for independent adjustment of resistance in opposite directions of movement of the exerciser members. This is accomplished by use of opposed check valves having individual bypass paths and flow control valves.

Granted: 1993-09-28
Abstract: ABSTRACT          Process and device for detecting and evaluating surface cracks in workpieces.    A process and device for detecting and evaluating surface cracks in workpieces wherein a picture is produced of the surface of the workpiece by means of a video camera and said picture is digitized and is processed by means of a computer to produce a binary picture of any cracks present and a sorting report is triggered when a preselected threshold level is exceeded.  In order to obtain a sorting signal that is independent of the absolute brightness of the original picture a blurred background picture is derived from the original picture levels that have been converted to digitized grey shade levels and subtracted from the original picture, the difference picture formed in this way giving the crack representation.  A dynamic threshold level for the sorting signal is determined by comparing the grey shade distribution of the original or the difference picture with at least one previously evaluated or difference picture and a binary picture is produced from the original or the difference picture and the grey shade threshold, and picture elements with their grey shades exceeding the set threshold are indicated as defects.  The surface of the workpiece may be pre-treated by the magnetic powder or dye penetration process and/or contrast intensifying means.

Abstract: A waste tank for a vacuum sewage system installed in a transport vehicle comprises a receptacle portion for receiving sewage up to a predetermined maximum filling level.  The tank defines an inlet opening for admitting air and sewage to the tank and an outlet opening for exhausting air from the tank.  The inlet and outlet openings are above the maximum filling level of the tank.  The tank also comprises an inlet separator that separates air and sewage entering the tank by way of the inlet opening using the kinetic energy of the sewage, and thereby dissipates kinetic energy of the sewage so that sewage entering the receptacle portion of the tank does not do so in a violent fashion, such as to contribute to vigorous movement of the sewage or cause splashing.
