Granted: 1993-01-12
Abstract: Abstract APPARATUS AND METHOD FOR MANIPULATING      AND ANCHORING TISSUE           An apparatus and method for manipulating and anchoring tissue is provided.  The invention is directed to solving the problem of manipulating and anchoring tissue within a joint when access to that tissue is limited, for example, during arthroscopic surgery.  The apparatus includes an anchor member (10, 50) with attached suture (12, 52).  The anchor member (10, 50) is lodged within the tip of a needle (14, 54), which is inserted into a joint.  A tube (16, 55) fits within the needle (14, 54) and is pushed toward the needle tip to expel the anchor member (10, 50) into or behind the tissue to be manipulated or anchored.  The suture (12, 52) is thereafter available for manipulating or anchoring the tissue.  In one embodiment, the anchor member (80) is configured to provide anchorage of its attached suture (82) within a hole (100) drilled into a bone (96).  A retainer (58, 69) slides over the suture (12, 52, 82) and secures tissue to the anchor member (12, 52) or to the bone (96) in which the anchor member (82) is anchored.

Title: Variable load valve
Inventor: HART JAMES E
IPC: B60T8/18

Granted: 1992-07-28
Abstract: (Case No. 8415) ABSTRACT OF THE INVENTION   A variable load brake control equipment for a road/rail type vehicle comprising  variable load brake apparatus located between the auxiliary reservoir and a supplemental volume reservoir in the supply line upstream of the vehicle control valve device. During braking, the auxiliary reservoir pressure and the supplemental value reservoir pressure combine to provide an unmodulated buildup of brake pressure until the brake pressure reaches a value that varies as a function of the vehicle load.  At this point, the variable load valve device operates to isolate the auxiiary reservoir, so that a continued buildup of brake pressure is modulated by reason of the fact that the supplemental volume reservoir alone supplies braking pressure.

Granted: 1992-09-22
Abstract: ABSTRACT            A regenerative burner system comprises two burners alternately fired and each having an air and fuel supply thereto traversing separate heat  exchangers.    The  arrangement  is  such  that  the  hot  gases exhausted from the furnace during firing of the one and the other burners traverse the heat exchangers associated with the other and the one burners,  respectively,  relinquishing heat thereto whereby both the fuel and the air supply to each burner extracts heat from its  associated  heat  exchanger  during  the  firing  cycle  of  that burner.            By heating both the fuel  and  the  air input to  the  regenerative system, fuels of low calorific value, e.g. blast furnace gas or any gases low in or devoid of hydrocarbons may be efficiently utilised to provide a stable high temperature flame without the need for enrichment with `pilot' fuels.

Abstract: A wheeled support assembly 10 is manually pushed over the ground and has a motor 22 rotating an antenna assembly 60 about a vertical axis 24.          Encoders 128 on the antenna shaft 20 and on a wheel axle encode antenna angular position and position over the ground.  Transmitted pulses and received data pass through a rotary microwave connector 26.  For example, 400 sets of pulses are emitted at equal angular intervals in each revolution of the antenna assembly.  The interval between pulses is e.g. 12 microseconds, with 256 pulses per set.  Noise reduction is achieved by processing the received data accordingly.  In a modification the rotary connector 26 is single channel with some electronic stages mounted on the rotating antenna assembly.  Power is coupled to them via the microwave cable.  An umbilical connects the assembly 10 to a support facility including a computer.  Alternatively, battery power is used with data transferred radiatively.

Abstract: ABSTRACT OF THE DISCLOSURE    A field sequential color shutter display system including a light source emitting light rays having substantially first and second different primary colors. First and second light polarizing filters are included.  The filters are aligned in optical communication with the source. Each filter includes a color selective polarizing filter having substantially orthogonally oriented absorption axes. The first absorption axis of each light polarizing filter passes linearly polarized light of the first color and a uniform first polarization.  The second absorption axis of each light polarizing filter passes linearly polarized light of both the first and second colors and a uniform second polarization.  Variable optical retarding filters are disposed between the first and second light polarizing filters.  Switching filters are in communication with the variable optical retarding filters to selectively provide first and second switching states to produce respective first and second amounts of optical retardation to develop, over a relatively broad range of viewing angles, a light output through the second light polarizing filter of either the first color, or, a composite light output containing both the first color, having both the first and second polarizations, and the second color having only the second polarization.

Abstract: Abstract of the Disclosure A feedthrough fitting for sealing around at least one conduit extending longitudinally through a cutout in wall at a transverse spacing from an inner surface of the cutout has an elastomeric one-piece seal having a pair of longitudinally opposit-ely directed faces, an outer surface corresponding generally to the inner surface, at least one longitudinally throughgoing passage extending between the faces and to the conduit, and at least one lateral split extending completely longitudinally between the faces and completely laterally from the passage to the outer surface. Thus the seal can be spread at the split to fit around the conduit. A respective end plate covers generally all of each of the faces and is formed of a plurality of separate sections together forming a hole corresponding to and longitudinally aligned with the pas-sage.  The sections of each pair are formed to a lateral side of the passage generally opposite the split with interfitting substan-tially part-circular edges and meet laterally at opposite edges to the opposite lateral side of the passage.  Fasteners engaging lon-gitudinally through the two plates and seal longitudinally compress the seal and force the outer surface against the inner surface.
