Title: Optical fibre loss detection
Inventor: THOMAS GLENN A
IPC: G01M11/00
Filed: 1991-04-08
Abstract: Apparatus is provided for detecting losses in a branched optical fibre network comprising a first optical fibre (17) and a plurality of second optical fibres (A, B) each of which is coupled to the first optical fibre. The first optical fibre (17) constitutes a main line, and the second optical fibres (A, B) constitute branch lines. The apparatus comprises launch means (13, 14, 16) for launching a carrier wave into the main line (17), respective modulating means (11a, 11b) in each of the branch lines (A, B) for modulation the carrier wave in that branch line, return means (12a, 12b) for returning the modulated signals along the branch lines to the main line, and monitoring means (20, 21a, 21b) for monitoring the main line for changes in the modulation of the returned signals. The modulation means (11a, 11b) are such that each modulates the carrier wave differently.

Title: Seismic Network Bay Frame
Inventor: HALL JAMES R
IPC: H05K7/18
Filed: 1993-05-31
Abstract: The invention addresses both the seismic and electromagnetic emissions requirements in the area of the frame where the upright frame members and the top frame member and base frame member are interconnected. To this end, the top frame member has two offset extensions on each end which interlock with interiorsurfaces of the upright frame members by projecting through notches in the upperportion of the upright frame members. The upright frame members and the top frame member are then welded together and the outer surfaces of the welded members are ground flush to provide smooth continuous planar electromagnetic interference (EMI) gasket mating surfaces. An additional reinforcing offset member is positioned against and along each end of the top frame member in the area which engages the interior wide flange portion of each of the upright frame members. These additional reinforcing offset members project through notches in both the top frame member and the corresponding upright frame members. The reinforcing offsetmembers are fillet welded to both the top frame member and the upright frame members. Another additional reinforcing angle member is attached to each of the upright frame members in the area of their bottom internal wide flanges and are fillet welded to the corresponding upright frame members. The upright frame members are welded to the base frame member and the outer surface of the welds is groundflush to provide smooth continuous planar EMI gasket mating surfaces. (FIG. 1)

Abstract: METHOD FOR TRANSFORMING MONOCOTYLEDONOUS PLANTS            Abstract of the Disclosure A method for delivering foreign genetic material into immature embryos isolated from monocotyledonous plants, paticularly those of the Gramineae family is described. The method involves the isolation of immature embryos from the desired plant species, culturing the immature embryos for a period of time on a medium capable of inducing callus formation, introducing the foreign genetic material into the immature embryos and selecting transformed callus tissue to be regenerated into whole plants. Immature embryos that have undergone the culturing process prior to transformation exhibit a higher frequency of transformation when compared to that from freshly isolated immature embryos. The genetic material is preferably delivered by either electroporation or microprojectile bombardment methods.

Title: Trapeze for windsurfers and sailors
Inventor: KIAULEHN RONALD
IPC: B63B35/79
Filed: 1993-08-27
Abstract: Abstract The chest trapeze (1) is cut from a flexible panel (2) that is of plastic, and this is then stitched into a tear-proof covering (3) that is of woven plastic material, e.g., a nylon fabric.  The chest trapeze (1) incorporates a back part (4), two hip and stomach parts (5, 6) that extend transversely to this, and two shoulder pieces (7, 8) that are joined to the back part (4).  A support for the lumbar vertebrae (10) of a windsurfer's or sailor's spine (9), which consists of supporting elements (11) that intermesh with each other and that are of limited flexibility, is incorporated into the back part (4).  The manner in which the supporting elements (11) that are integrated into the back part (4) of the trapeze (1, 33) operate is such that when the windsurfer leans back they slide together to form a stiff supporting band (46) that matches the curvature of the spinal column (9) in the lumbar area (10); when the windsurfer leans forward they spread apart to form a flexible articulated band (47).

Title: Web imprinting apparatus and method
Inventor: WEHRMANN RICK S
IPC: B65H23/188
Filed: 1994-05-05
Abstract: ABSTRACT   An improved printer is disclosed which has upright and inverted printers for printing either or both faces of a flat web. A stepper motor driven nip is provided to feed the web along a path of travel past the two imprinters. The web is driven at a relatively high feed speed until sections of the web to be imprinted are registered with the imprinters, whereupon the feed speed is reduced to a slower imprinting speed. Upon completion of the imprinting, web feed is returned to thehigher rate providing a downstream dancer is in condition to accept the web at the higher rate. If the amount of web accumulated in the downstream dancer exceeds a predetermined level, the motor is stopped until the dancer is in condition to receive the web at the higher feed speed rate.

Abstract: A combined inlet structure and switching device for a central vacuum system includes an inlet housing having top, bottom and side walls defining a vacuum inlet chamber and a front with a dirt receiving opening.  An aperture is located in the top wall and can be connected to a pipe leading to a central vacuum source.  A closure member is movable between first and second positions in order to close or open the aperture.   A foot operated actuator is connected to the housing and is able to pivot the closure member between the first and second positions.   A spring biases the closure member  towards  the  first position and operates when the actuator is pressed in one direction.  When the closure member is moved to the second position, it will remain there unless the actuator is pressed in another, opposite direction. There is also a switch mechanism responsive to movement of  the actuator  for  opening  and  closing  an  electrical  circuit connected to the central vacuum source.

Title: Optical fiber preform, optical fiber and their manufacturing methods
Inventor: HOSHINO SUMIO
IPC: C03B37/027
Filed: 1994-06-22
Abstract: ABSTRACT OF THE DISCLOSURE    An optical fiber preform of the present invention comprises a core made of a transparent material in a central region and a cladding made of a transparent material in a peripheral region, and the optical fiber preform is uniformly twisted in the core in one direction or around a central axis passing through in the vicinity of said core in one direction, and has a length longer than a twisted pitch, so that an optical fiber which is drawn from the preform has uniform twists remained in one direction, and polarization dispersion which occurs in an optical signal propagating in the optical fiber appears around an optical axis in 360° direction and is cancelled out one after another; therefore, the entire polarization dispersion can be suppressed.  Further, the optical fiber may be twisted in a step of vitrifying or pulling during optical fiber manufacture, which does not cause a rise in the processing cost.

Title: Lamp having controllable characteristics
Inventor: DOLAN JAMES T
IPC: H01J61/02
Filed: 1993-04-13
Abstract: The spectral energy characteristic of a discharge lamp is controlled by changing the density of the fill substance. The spectral characteristic can be shifted while substantially maintaining its shape by changing the density of the fill. A sulfur or selenium containing discharge lamp which is operated at a pressure of at least about 1 atmosphere contains a low ionization potential substance in the fill. Characteristics which are improved are one or more of spatial color uniformity, extinguishing characteristics, and bulb starting reliability. Particular substances which are added to the fill are alkali metal containing substances, III B metal containing substances, and alkaline earth metal containing substances. When light is reflected back into the bulb, the light which is re-emitted is stronger in the higher wavelengths.
