Title: Recombinant adeno-associated virus vectors
Inventor: LEBKOWSKI JANE S
IPC: C12N15/869
Filed: 1991-10-30
Granted: 1995-10-03
Abstract: A simplified method to produce recombinant adeno-associated virus (AAV) vectors is described. The procedure involves the use of chimeric plasmids which incorporate the Epstein Barr nuclear antigen (EBNA) gene, the latent origin of replication of Epstein Barr Virus (oriP), and a recombinant AAV genome.  The chimeric plasmids themselves are also a part of the present invention.  These EBV/AAV plasmids are maintained as multicopy extra-chromosomal elements in cells, such as human 293 cells.  Permanent cell lines carrying these EBV/AAV plasmids are induced to produce large amounts of recombinant AAV virus upon addition of wild-type, adeno-associated virus helper functions.  Recombinant AAV vectors produced in this manner are capable of transducing exogenous genes into other human cell lines and exhibit all of the attributes of viral elements produced by conventional methods.

Title: Multi-port microwave coupler
Inventor: TONDRYK WIESLAW JAN
IPC: H01Q25/00
Filed: 1992-07-14
Granted: 2002-09-17
Abstract: A multi-port microwave coupler has six input ports In 1, In 2, In 3, In 4, In 5 and In 6 and six output ports Out 1, Out 2, Out 3, Out 4, Out 5 and Out 6 and is synthesised from nine 2 x 2 90° hybrid couplers which are arranged as three sets, that is a first set A, B and C, a second set D, E and F and a third set G, H and I. A first group of transmission lines 11, 12, 13, 14, 15 and 16 interconnect the first and second sets of hybrid couplers, and a second group of transmission lines 21, 22, 23, 24, 25 and 26 interconnect the second and third sets of hybrid couplers.     The first and third sets of couplers each give a 3dB power reduction, but the second set give a 1:2 power split between their outputs. Three 90° phase shift devices X, Y and Z correct the phase of the signals in the transmission lines 21, 25 and 24 respectively. When equal amplitude signals are applied to all of the input ports, the combined signal can be directed to any one of the output ports by appropriately selecting the respective phases of the input signals. The first and second groups of transmission lines can be arranged as respective transmission rings so that all cross-overs in the transmission lines are avoided thereby providing a planar realisation of a 6 x 6 multi-port microwave coupler. The invention is of application to higher order n x n multi-port microwave couplers where n = 2p x 2q with both p and q as whole numbers.

Title: Plunger for preventing a dead air space in a blender
Inventor: JENNETT DAVID
IPC: B01F15/00
Filed: 1993-03-10
Granted: 2004-02-17
Abstract: An accessory (10) for a blender includes a generally cylindrical handle portion (11), a generally cylindrical plunger portion (12), and an enlarged circular stop disk portion (13) between the handle portion (11) and the plunger portion (12). The plunger portion (12) is received within a pitcher portion (14) of the blender through an aperture (21) in the cover (15) of the blender.    A mixing blade assembly (24) is positioned near the bottom of the pitcher portion (14) and the length of the plunger portion (12) is such that when the stop disk portion (13) rests on the cover (15), the bottom of the plunger portion (12) is just above the mixing blade assembly (24). An air channel defining member, shown in the form of a bearing housing (23) of the mixing blade assembly (24), would normally cause an air channel to be formed in the fluid (F) in the blender ultimately forming an air pocket around the mixing blade assembly (24). However, the plunger portion (12), which is preferably of a diameter approximating that of the bearing housing (23), prevents the formation of the air channel and ultimately any air pocket.

Granted: 1998-09-29
Abstract: In a blown film extrusion system in which film is extruded as a tube from an annular die and then pulled along a predetermined path, an apparatus is provided for gauging and controlling the circumference of the extruded film tube. At least one transducer, preferably ultrasonic, is mounted adjacent the extruded film tube for transmitting and receiving interrogating pulses along paths normal to the extruded film tube, and for producing a current position signal corresponding to the circumference of the extruded film tube. The current position signal is continuously compared with at least one previous position signal, preferably with a computer program resident in a controller memory. If at least one preselected condition is violated, the current position signal is disregarded in favor of an estimated position signal. The quantity of air within the extruded film tube is varied in response to either the current position signal or the estimated position signal to maintain the extruded film tube at a preselected circumference. The transducer may be mounted to an adjustable sizing cage, and is thus moveable inward, outward, upward, and downward relative to the extruded film tube as changes are made in its circumference or frostline position. A pair of controllers may be employed to establish two minimum circumference values, and two maximum circumference values. If a collapsing or overblown extruded film tube is detected, the system goes into override, and the flow of air is either accelerated or decreased to counter the alarm condition. The system of the present invention also allows for automatic startup. In a startup mode, the current position signal is continuously compared with a selected minimum circumference threshold. Once the selected minimum circumference threshold is exceeded, the system switches to an operating mode which continuously compares the current position signal with a selected setpoint value to maintain the extruded film tube at a desired circumference.

Granted: 1998-09-01
Abstract: A  transfermix  includes  a  component  having  an internal operating surface provided with a helical thread and  an  interior  component  having  an  external  operating surface  provided  with  a  helical  thread  of  a  different direction  but  coaxial  with  the  helical  thread  on  the component having the internal operating surface, the helical threads facing one another and defining a passage for a medium to be mixed.   The envelope defined by the crown of the interior thread is within the envelope defined by the crown of the exterior thread up to and including coincidence of  the  envelopes,  and  the  cross-sectional  areas  of  the grooves  of  the  facing  threads  vary  in  opposite  senses between  a maximum and  a minimum value  for  each of  the threads along substantially the same length of the passage. The helical thread of which the groove cross-section  is being reduced comprises at least two starts of which one over a part of the axial length is reduced in groove cross-section at a lesser rate than the other is so reduced and over a different part of the axial length the first start is reduced in its groove cross-sectional area at a faster rate than the other is so reduced.  In this way in operation the medium is caused to move in the passage, portions thereof are transferred between the grooves of the facing helical threads  as  giver  and  taker,  with  some  portions  in  the initially more slowly reducing start of the giver-groove being transferred  into the  taker-groove  later  than  some portions in the other start of the giver-groove,  whereby over the axial length of transfermix geometry a measure of longitudinal  mixing  is  effected  in  addition  to  the transverse mixing.
