Title: The preparation and use of a new ziegler-natta catalyst component
Inventor: KORVENOJA TARJA
IPC: C08F4/638
Filed: 1989-12-21
Granted: 1999-08-17
Abstract: The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefines, in which particles are formed of magnesium dihalide and alcohol, the particles are reacted with an organic compound of a metal from the groups I-III, the thus obtained particulate product is activated by means of a titanium and/or vanadium compound and optionally a donor, and optionally a prepolymerization is carried out for the activated particles. A problem of such a method is how to form particles of magnesium dihalogenide and alcohol having a structure advantageous for the polymerization of olefins. The problem has in the present invention been solved so that the particles are formed by spray crystallizing (spray freezing) a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol. The hydroxyl content of the particles so obtained is much greater than earlier, which results in a much more active procatalyst than the preceding ones.

Title: Full swing golf trainer
Inventor: NOVOSEL JOHN M
IPC: A63B69/36
Filed: 1991-01-04
Granted: 2005-12-20
Abstract: A golf club shaft is provided with a training head that, when the club is swung, strikes a movable, upright target composed of a yieldable, light-weight material. The target presents a relatively broad, laterally facing target surface and, when struck, becomes attached to the head and is carried thereby through the remainder of the swing. The addition of the target to the head provides increased resistance to train the player to increase club head speed at impact and beyond. The training head provides visual feedback at the finish so that the player will know whether a proper swing was executed.

Title: Process for improved sulfure production from sulfure production unit using acid gas containing hydrogen sulfide
Inventor: KVASNIKOFF GEORGES
IPC: G05D11/13
Filed: 1990-10-18
Granted: 1999-06-29
Abstract: Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2  >/=  2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180  DEG C and 700  DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).

Abstract: A  pressure  sensitive  adhesive  tape  roll  for selective use on a lint remover roller assembly has a core and a non-adhesive tape substrate.  The tape substrate has a first  portion  on  one  side  thereof  covered  with  a longitudinally extending adhesive layer and a second portion defining a narrow uncovered substrate portion therealong.          The  first  and  second  portions  form  a pressure sensitive adhesive  tape  with  the  pressure  sensitive  adhesive  tape being adapted for selective winding on the core with the adhesive  layer  of  the  tape  facing  outwardly  to  form  a pressure sensitive adhesive tape roll.  A slit is provided through the adhesive tape roll across the adhesive layer first portion thereof to define a narrow unslit uncovered substrate  second  portion  which  maintains  the  retentive longitudinally   continuous   integrity   of   the   pressure sensitive tape roll on the core.   Each layer of the tape roll  is  selectively  detachable  upon  saturation  from  the adhesive tape roll by lifting it away along the slit and tearing it away through the narrow unslit portion of said substrate to expose the next lowermost unused adhesive tape layer.

Title: Apparatus for rezeroing an in vivo pressure sensor and method for rezeroing
Inventor: GUSTAFSON GARY E
IPC: A61M25/00
Filed: 1991-07-05
Granted: 1995-08-22
Abstract: A sensor assembly for an in vivo physiological pressure measurement has a member with a distal end to ease placement of the catheter sensor assembly in vivo.   A passage  is  preferably  in  an  intermediate part  of  the member  and  is  open but  covered by a pressure responsive sensor sealing the passage.  The sensor has a first side away from the intermediate part for exposure to in vivo physiological pressure and a second side  in fluid communication with the passage.  A pressure connecting means for inhibiting liquid    communication    located    between    the physiological pressure and the passage  is  arranged for selectively connection therebetween so that when connected the pressure on the first and second sides of  the  sensor  can  be  substantially  equalized.   A control ex vivo makes the selective connection of the second   side   of   the  pressure   sensor   and  the physiological pressure.  A method for rezeroing an in vivo pressure sensor has  the steps  of obtaining a signal from the first side of the sensor at distal end, using a pressure substantially equal to the in vivo  pressure  and  applying  that  pressure  to  the second side of the sensor.

Abstract: A method of disposal of waste material on subaqueous ground is disclosed, and comprises transporting the material to a location above a selected site for disposal, conveying the material in a vessel to a level at, or close to, the subaqueous ground, and depositing the material onto the subaqueous ground. The vessel travels under free-fall conditions for part of its descent. Also provided is a vessel which comprises a generally cylindrical body comprising a containment area having an opening at its upper end for receiving material which is to be transported by the vessel, and having at its lower end means for permitting egress of the material. The vessel is provided, at a position intermediate its upper end and its centre of mass, with at least two wing-like members at diametrally opposed positions; and is also provided with means for pivoting the wing-like members between a first position in which they lie substantially flat against the exterior of the vessel and a second position in which they extend outwardly from the body of the vessel. In the second position, they present an increased surface area to the surrounding water and provide thereby a decelerating effect on the motion of the vessel when the vessel is moving downwardly within the body of water.        A marine system for subaqueous waste disposal is also disclosed, which comprises a ship and a vessel generally as described above.

Title: Broadband conformal inclined slotline antenna array
Inventor: SALVAIL GARY
IPC: H01Q21/20
Filed: 1992-08-26
Granted: 1997-04-22
Abstract: A missile guidance antenna that is conformal to the missile surface, dual-polarized and broadband.   Slotline notch array elements (30, 52) are inclined toward boresight for both the E and H-planes.  This inclination directs a greater portion of the energy toward the front of the missile.   The additional energy directed forward reduces the nullifying effects of the metallic skin on the tangen-tial E-field and enhances the performance of the other polarization.  The slotline elements (30, 52) can be packed with spacing close enough to allow for electronic beam steering without creating grating lobes in the field at the highest frequency of operation.

Granted: 1998-04-28
Abstract: A method of separating an aqueous colloidal solution by agglomeration into water and agglomerate of colloidal particles by applying voltage to the aqueous colloidal solution to promote the agglomeration of colloidal particles.  The frequency of the voltage to be applied to the aqueous colloidal solution is increased to about 10kHz to improve efficiency of agglomeration and suppress electrolysis of water.  As the frequency is increased, hydrogen is generated earlier than the reaction of oxygen generated by the electrolysis of water with the colloidal particles, thus not oxidizing the colloidal particles.          Further, as the frequency is increased, the colloidal particles tend to obtain a greater oscillation energy, thus facilitating the agglomeration thereof.
