Title: Method and apparatus for obtaining microgravity conditions, particularly in theterrestial gravitational field
Inventor: MESLAND DICK
IPC: G09B9/00
Filed: 1988-05-18
Granted: 1992-01-21
Abstract: The method involves impressing on the system an initial acceleration of suitable magnitude and subjecting the system to an acceleration stage of suitable duration. The direction of the acceleration is inclined to the vertical at a suitable angle so as to make the system follow a ballistic trajectory in the said gravitational field. The ballistic trajectory follows the acceleration stage and comprises an ascending phase and a descending phase whose respective durations define the total duration of the ballistic stage, i.e. the stage during which the system describes the said ballistic trajectory. The ratio between the durations of the ballistic and acceleration stages being more or less equal to the ratio between the magnitude of the initial acceleration of the system and the magnitude of the acceleration due to gravity. 
<??>The above sequence is repeated by again impressing on the system an initial acceleration at the end of each sequence, i.e. at the end of the descending phase. This repetition is carried out enough times to cover a predetermined period of time.

Title: Alarm for indicating fish striking bait
Inventor: FUCHS RICHARD
IPC: A01K97/12
Filed: 1988-07-07
Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE An alarm for indicating when a fish strikes bait at the end of a line associated with a fishing rod.  The alarm includes a plastic housing defining a receptacle with a rim and opening through which the fishing rod is received and a separate compartment where a sound generating unit is stored.  A movable receptacle part is integrally hinged to the housing and in a rest position defines a part of the rim against which the rod is rested.  The receptacle part is deflected outwardly to a strike position when the fish takes bait, but is otherwise restored to the rest position by the resilience of the plastic forming the hinge.  The sound generating unit is mounted on a plastic carrier which has a pair of prominent terminals connected to a speaker drive circuit.  A pair of conductive clip elements within the compartment serve both to retain the carrier is a releasable snap fit and to electrically contact the circuit through the carrier terminals.  A movable contact attached to the displaceable receptacle part and a stationary contact mounted on the housing are attached to the clip elements.  The movable contact is separated by an air gap from the stationary contact when the displaceable receptacle part is in the rest position, but contacts the stationary contact when the receptacle part is deflected to thestrike position, thereby closing the circuit and generating an audible alarm system.

Title: Process for preparing low dielectric polyimides
Inventor: ST CLAIR ANNE K
IPC: C08G73/10
Filed: 1988-07-14
Granted: 1993-01-19
Abstract: Abstract Linear aromatic polymers having low dielectric constants are produced by minimizing the electronic interactions between polymer chains.  This is accomplished by one or more of the following means: incorporating separator or linking groups in the polymer molecular structure  producing physical kinks or dissymmetry in the polymer chains; incorporating a bulky group in the polymer molecular structure; and incorporating one or more fluorine atoms in the polymer molecular structure.  Low dielectric aromatic condensation polyimides prepared according to this invention are highly suitable as film and coating materials for both industrial and aerospace applications where a high degree of electrical insulation, moisture resistance, mechanical strength, and thermal stability are required.

Title: Electric machine with a closed cooling loop
Inventor: KLEINHANS SIEGFRIED
IPC: H02K9/18
Filed: 1988-07-15
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE         In gas-cooled electric machines with a closed cooling loop which is distributed over two heat exchangers, arranged on the upper or under side of the machine, only part of the circulating cooling gas is cooled so that the electric machine must be taken out of operation because of the danger of local overheating.  In order to overcome this, baffles are arranged adjacent to the heat exchangers so as to block the cooling gas on half the side of the opposite axial cooling gas passage regions of the heat exchangers, thus subdividing the cooling gas stream into two halves with opposite flow directions.  The partial transfer of the cooling gas stream halves to the entire width of the axial cooling gas passage areas of the heat exchangers provides turbulence and a distribution of the cooling gas for uniform cooling also in the event of a failure of one heat exchanger.

Title: Bonded array of transmission media
Inventor: JACKSON KENNETH W
IPC: G02B6/44
Filed: 1989-05-31
Granted: 1994-08-23
Abstract: BONDED ARRAY OF TRANSMISSION MEDIA Abstract A bonded optical fiber array (20) includes a parallel coplanar array of longitudinally extending contacting optical fibers (22-22). Each optical fiber is enclosed in inner and outer layers of coating materials and is provided with a color identifier. The inner layer is comprised of a UV curable bonding material having a modulus in the range of about 1 M Pa. For mechanical protection, the outer layer is a UV curable bonding material having a modulus in the range of about 1 GPa. When the optical fibers are disposed in the parallel array, interstices are created between the fibers and between the fibers and an envelope which is spaced no further than about 25 µm at its closest point to each fiber. A UV curable matrix bonding material which has a modulus having a value less than that of the outer coating layer on the fiber and more than that of the inner coating layer fills the interstices, extends to the peripheral line which defines the envelope and bonds together the optical fibers. The modulus of the matrix material and the bond of the matrix material to the color identifier on the optical fibers is such that interfiber and interribbon movement is allowed. Also, accessing of the individual fibers is allowed upon the application of peeling forces by a craftsperson without the need for complex tools and without obfuscating the color identifier.
