Title: Dropper assembly for liquid feed and method of feeding liquid composition to a freezing chamber
Inventor: JONES CURT D
IPC: A23G9/40
Filed: 1996-03-28
Abstract: A dropper assembly (10) for feeding liquid composition (20) to a freezing chamber (12) comprises a tray (28) having a plurality of feed elements (40) that are designed to provide regulated discharge of the liquid composition (20) from the tray (28) and to feed the liquid composition (20) into the freezing chamber (12) in uniformly sized droplets (38). The feed elements (40) each comprise a projection (44) that is downwardly disposed in relation to the tray (28). The tray (28) has a bottom wall (30) with a plurality of orifices (42), each orifice (42) associated with a corresponding projection (44). The projection (44) has an inlet opening (48) associated with the corresponding orifice (42) in the tray (28) and an outlet opening (52) where droplets (38) are formed and released. The dimension of the inlet opening (48) is greater than the dimension of the outlet opening (52). The narrowing taper of the flow channel (54) that extends from the inlet opening (48) to the outlet opening (52) promotes regulated accumulation of liquid composition (20) to facilitate regulated discharge and formation of uniformly sized droplets (38). An inventive method is also provided for feeding liquid composition (20) to a freezing chamber (12) to form uniformly sized beads (18) of frozen product.  The inventive method utilizes the novel dropper assembly (10).

Title: System for energy recovery in a vacuum pressure swing adsorption apparatus
Inventor: SMOLAREK JAMES
IPC: B01D53/04
Filed: 1998-01-27
Abstract: A VPSA apparatus includes a first adsorbent bed and a second adsorbent bed, a feed blower for providing a flow of a gas mixture at about atmospheric pressure to the beds, and a vacuum blower for removing a flow of gas therefrom and venting the gas to a space at atmospheric pressure. The VPSA process causes the first adsorbent bed to be poised for evacuation by the vacuum blower and concurrently, the second adsorbent bed is under vacuum conditions and is poised for pressurization by the feed blower.  A single motor is coupled by a common shaft to both the feed blower and the vacuum blower and operates both.  A conduit/valve arrangement is operative during at least a portion of a process time when the adsorbent beds are in pressurizing/evacuation states, respectively, to couple the feed blower to the second adsorbent bed when at vacuum and for concurrently coupling the vacuum blower to the first adsorbent bed which is to be evacuated.  The feed blower is thereby caused to operate in a gas expansion mode and imparts expansion energy, via the common shaft, to the vacuum blower.  During idling conditions, a valve-conduit system is controlled to enable significant reductions in pressure rise across the feed and vacuum blowers.

Title: Multi-position jack frame
Inventor: ARNETT JAIME RAY
IPC: H01R13/74
Filed: 1998-03-31
Abstract: A jack frame includes a jack frame block having a front surface, a pair of side surfaces and a top surface. The front surface has a plug opening with a plug axis along which a plug connector can be inserted to connect to the jack frame block. The front surface is dimensioned to be received in a jack opening in a face plate, and the inner periphery of the jack opening is defined in part by a pair of side walls and a top wall. The top surface of the jack frame block has a first surface portion that extends at a first angle relative to the plug axis of the plug opening in the block's front surface, and a second surface portion that extends at a second angle relative to the plug axis. Either the first or the second surface portion can be aligned with the top wall of the jack opening, so the frame block can be mounted on the face plate with a desired orientation depending on which one of the first and the second surface portions is aligned with the top wall of the jack opening. Engagement members on the frame block are arranged to engage walls of the jack opening when the frame block is mounted in the desired orientation, to limit movement of the frame block relative to the face plate.

Abstract: Occlusion of vessels, particularly small diameter vessels, is effected with an intravascular occlusion device comprising an anchor (10, 10', 30, 60) and an occlusive material or materials (16, 18, 44).  Embodiments of the anchor include self-expanding (10, 60) or mechanically expandable (10', 30) frames comprising a plurality of wire-like members (12, 12')or a generally cylindrical, tubular-shaped member (32).  Examples of the occlusive materials include filamentary strands or fiber bundles (16), and/or a non-compliant or inelastic closure member (18, 44).  The strands or fiber bundles (16) are secured to the anchor by tying or adhesive.  The non-compliant occlusion member (18, 44) is connected to the anchor by tying, molding, coating, adhesive, induction heating, welding or heat shrinking.  The fiber bundles (16) are preferably made from material which induces a thrombogenic response.  Both the fiber bundles (16) and the inelastic occlusion element (18, 44) may be coated or impregnated with thrombogenic materials or agents.          Additionally, the surface of the anchor can be treated to increase the thrombogenic response of the occlusion device.

Abstract: A catheter including a tubular profiled end section (2) with an inlet portion (3) provided with a flexible ring-shaped circumferential stop (4), and an outlet end (5) provided with a central dispensing port. Helical circumferential threads (7) are distributed between the stop (4) and the outlet end (5). The stop (4) includes a plurality of fine ring-shaped rib portions (41, 42, 43, 44) closely axially spaced so that they are mutually engageable when exposed to an axial bending force, and their bending strength thus increases above a predetermined bending threshold. A good balance is thus achieved between the softness needed to avoid injuries to the animal being treated and the stiffness required for sealing contact in the region of the cervix during insemination.

Title: A method of determining the density profile
Inventor: TELLER STEEN
IPC: G01N23/16
Filed: 1997-02-14
Abstract: A method of determining the density profile of a plate-shaped material M, th e density of which varies discretely or continuously across the plate thicknes s, whereas the density at a specific depth of the plate M is preferably assumed  to be constant. The inventive method employs X-rays or .gamma.-rays from a source K. The latter source K is placed on one side of the plate M, whereas at least two detectors T, F are arranged on the opposite side of the endless plate being advanced during the measuring in the longitudinal direction. A first detector T is preferably placed in the radiating direction of the sour ce and measures the transmittent radiation through the plate M, and the second detector F is placed outside the radiating direction of the source K and measures the scattered radiation on partial volumes along the radiating direction of the source. Based on the signals measured by the detectors it i s possible to measure the density in each individual partial volume. According  to the invention a compensation has furthermore been carried out for multipl e scattered radiation by the measured radiation being deducted from the multip le scattered radiation.

Title: Imaging self-referencing tracker and associated methodology
Inventor: LIVINGSTON PETER M
IPC: G01S17/66
Filed: 1998-07-22
Abstract: A method of maintaining a laser weapon target aim point. The method includes the step of selecting an aimpoint (42) on a target (24). The target is then engaged with a laser beam (23). The tracker (36) then receives target scene information, and detects both a target image and a target laser hit spot (40). The tracker (36) then determines the vector distance between the target aimpoint and the target laser hit spot, and drives the vector distance (70) to zero to close the loop between the target aimpoint and the target laser hit spot location. The method and system of the present invention thereby increase the probability of a target kill by enabling the tracking system to maintain a laser lock on the target aimpoint from an initial target engagement to a target kill stage.
