Title: Reversible optical or electro-optical connector
IPC: G02B6/38
Filed: 1989-08-10
Abstract: An electro-optical connector having a plug containing a center 
light emitter or detector and an interconnected pair of light detectors or 
emitters symmetrically positioned with respect to the center light emitter or 
detector. A socket, also containing a center light detector or emitter and an 
interconnected pair of symmetrically positioned outer light emitters or 
detectors, is adapted to receive the plug. The plug may thus be inserted into 
the socket with a plurality of angular orientations. The plug is retained in the 
socket by a pair of resilient tabs extending into respective recesses in the 
socket. The tabs may be removed from the recesses by exerting an outward 
force on the tabs, either directly or by exerting a transverse force on the plug 
thereby generating a rotational moment on the plug that exerts an outwardly 
directed force on the tab. As a result, the plug may be removed from the 
socket by exerting side forces on the plug without damaging the plug or 
socket.

Title: Tdma satellite communications system operating in wide and narrow aperture modes for receiving bursts of various timing deviations
IPC: H04B7/212
Filed: 1989-11-30
Abstract: In a satellite communications system, a time slot assignment signal and 
a reference timing signal are transmitted from a central station to terminal 
stations to allow them to send bursts on assigned time slots and to establish 
the frame timing. In the central station, first and second self-resettable 
counters (8,17) increment their respective binary counts at clock intervals and reset 
their counts to an initial value at time-slot intervals. A local timing signal is 
generated synchronously with the reference timing signal and delayed by an 
amount corresponding to a minimum round-trip propagation delay to reset 
the first counter (8). In an initial, wide aperture mode, the output of the first 
counter (8) is used to generate control signals for recovering a carrier and clock 
and widely opening an aperture gate (15) for detecting unique words of a burst 
that is affected by satellite drift. If a unique word is detected, the central 
station switches to a narrow aperture mode in which the output of the 
second counter (17) is used instead to generate control signals for recovering the 
carrier and clock and narrowly opening the gate (15) to reduce the possibility of 
detecting false unique words. In a preferred embodiment, the output of the 
second counter (17) is stored in a memory in response to the detection of a unique 
word and an average value of the stored counts is derived to optimize the 
reset timing of the second counter (17).

Filed: 1989-05-31
Abstract: Method and apparatus for fabricating multiple 
layer sheet materials are adapted to minimize the time of 
exposure of a sensitive polymeric melt stream to contact 
with metal. The method comprises encapsulating the 
sensitive melt stream (12) with a second polymeric melt 
stream (16) which preferably is of a lower viscosity, at 
the outlet of the apparatus or extruder (10) which 
produces the sensitive melt stream (12). When the 
encapsulating melt stream (16) has a lower viscosity than

elongated pipe - is preferably employed between the 
encapsulating means (20) and an extrusion die (42), 
whereby thickness variations about the circumference of 
the encapsulating melt stream (16) are reduced.  
     The method and apparatus are especially 
beneficial for the extrusion of vinylidene chloride 
copolymers in the manufacture of multi-layer packaging 
films containing one or more layers of VDC copolymers.

Title: Method for producing a conductive oxide pattern
IPC: G02F1/1333
Filed: 1990-06-12
Abstract: A conductive oxide film (2) is formed on a substrate (1) at a low 
temperature. The formed conductive oxide film (2) is not very dense 
because of the low temperature. Therefore the formed conductive 
oxide film (2) can easily be etched by an etchant having a weak 
etching capability. And by the etching a pattern of the formed 
conductive oxide film (2) is produced. The patterned conductive 
oxide film is oxidized at a temperature in the range of 100-­
400°C. In this way a conductive oxide pattern is produced in a 
shorter time in the method of the present invention than in a 
conventional method and the conductive oxide pattern produced by 
the method of the present invention has the almost same 
resistivity as the conductive oxide pattern produced by the 
conventional method and has an improved pattern edge and an 
improved reproducibility.

Title: Method and apparatus for sensing the condition of casting belt and belt coating in a continuous metal casting machine
IPC: B22D11/16
Filed: 1991-12-05
Abstract: Method and apparatus for continuously sensing and monitoring the conditions of tensed flexible endless metallic casting belts (12,14) and their insulative coatings in a continuous metal casting machine. The flatness of a casting belt (12, 14) is continuously monitored and thereby also the condition of its thermal protective coating. One or more non-contacting eddy-current sensing probes (36, 38) are placed in proximity to the reverse coolant side of a belt (12, 14) for sensing and measuring the distance of the belt from the probe to reveal irregularities in the flatness of the belt while it travels past the probe. A deficiency of insulative belt coating can cause variations in belt flatness during casting. By monitoring such variations an operator of the continuous casting machine is alerted that the coating needs to be retouched or replaced without interrupting the casting process. Or such monitoring can alert the operator that the belt (12, 14) has become inherently not flat. <IMAGE>

The tissue bag (301) comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag (301) material is foldable and flexible for insertion through an access sheath (302) into the surgical site and for forming a gas-tight seal when extended through the access sheath (302) or puncture site. A drawstring (310) is attached to the open end of the bag (301) to close the bag (301) when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin (304). After the closed open end of the bag (301) is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continully fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag (301) is completely removed from the surgical site area.
