Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE      A tire chain having a tread portion that connects an inner portion with an outer portion.          The inner portion is provided with a closure, one closure member of which, from a starting position, can be connectable and releasable from the other closure member via a twisting movement.   In the twisted position, a return force is operative that acts in the direction toward the starting position.          The torsional movement of this one closure member can be easily undertaken.  The return force that is operative in the twisted position automatically returns the closure member, after its release, into its starting position,  whereupon the closure is properly closed.

Abstract: Abstract of the Disclosure A method for logging a cased well to determine the quantity and location of any barite weighted drilling fluid in the annulus between the casing and the wall of the wellbore.  A tool assembly having a neutron generator and a gamma scintillation detector is used to log the zone of interest.  The neutrons introduced into the well by the neutron generator convert a portion of the barium-138 in the drilling fluid to barium-137m.  The magnitude of the gamma photon peak characteristic of the decay of barium-137 is used to identify the quantity of drilling fluid present in the annulus as a function of depth.  This method is especially useful identifying the existence of channels in a cemented wellbore annulus.

Title: Optimal flight guidance for aircraft in windshear
Inventor: ZWEIFEL TERRY L
IPC: B64C13/16
Filed: 1987-12-08
Granted: 1992-09-15
Abstract: ABSTRACT   An aircraft guidance system for optimizing the flight path of  an  aircraft  in  the  presence  of  a  windshear maximizes the time the aircraft remains in the air and the  distance  traveled  regardless  of  the magnitude  of  the  windshear,   in  the  presence of horizontal or vertical windshear  components,   while  effectively  minimizing  excitation  of  the aircraft's  phugoid  mode.   A  flight path angle is commanded sufficient to clear any  obstacle  that  may  be  found  in  the  airport  vicinity.   For longitudinal or horizontal shears,  a slightly positive constant flight path angle which is a function of the magnitude of the vertical wind is added  to the  slightly  positive  flight  path  angle  command  to produce a modified command that compensates for the decrease in flight path angle  relative  to the ground caused by the vertical wind.  The system inhibits exceeding stick shaker angle of attack by reducing the command signal until the actual angle of attack is equal to or less than the stick shaker angle of attack.

Abstract: ABSTRACT A ball return device for aiding in the practice of basketball or other games which require that a ball be returned to a player in order to perform repetitive practice routines.  The device comprises a receiving basket which may be placed under a basketball hoop and which directs a ball to a pair of rotating heads operable to propel the ball toward the player.  A detection apparatus on the return device is operable to sense the distance between a player and the return device.  When the distance between the player and the return device is within a zone of acceptable distances, an output signal is generated which causes the return mechanism to eject a ball toward the player.

Title: Method of producing a shrinkable product
Inventor: BORG TOMMI
IPC: B29C48/305
Filed: 1988-10-11
Granted: 1993-04-20
Abstract: Abstract The invention relates to a method for the production of a shrinkable product of a thermoplastic raw ma-terial by extrusion. The raw material (1) is extruded through a die (3) to form a pipe (18), whereafter the pipe is cut longitudinally in a cutter (7), spread out, and wound on to a reel (19, 17). A similar tech-nique has been used previously as well, but the prob-lem has been that without additives the product so ob-tained is not suitable for purposes such as the insu-lation, joining and covering of pipes. In the present invention, it is essential that the production rate is low and that rapid cooling is carried out in a cali-bration means (4). When reheated, a bandlike product (9) thereby shrinks vigorously and is welded to the object in question. (Figure 1)

Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE    The invention provides means for detecting errors in the transmission of protocol data words between the handset station and base station of a cordless telephone set.  Assuming the protocol data words are eight bits in length, a sixteen bit security code word is provided which consists of a high security byte and a low security byte.  At the transmitting station (either the hand set or base), the protocol data byte is exclusive-ored with both the high security byte and the low security byte.  The two resulting bytes are appended to the original protocol data byte to form a twenty-four bit error detection code.  This error detection code is transmitted to the receiving station.  The receiving station takes the unaltered protocol byte portion of the three byte word and exclusive-ors it with both of the other bytes of the received word.  If there were no transmission errors, the sixteen bit security code should be generated by the exclusive-oring step. If the resulting sixteen bit word does not match the security code stored in the memory of the receiving station, then an error is indicated and the receiving station request a retransmission of the data.
