Title: Method and apparatus for paging in a cellular moblie communications system
Inventor: MADHAVAPEDDY SESHAGIRI RAO
IPC: H04W68/08
Filed: 1996-04-10
Abstract: In a cellular mobile access communications system each mobile terminal registers its location at intervals. From the registration history of each mobile, a probable group of cells within which a mobile terminal may be located is predicted. When a mobile is to be paged, the paging message is transmitted to the predicted cell group. If no response is received from the terminal, the page message is then broadcast to further system cells. This reduces the overall paging load on the system.

Title: Multi-Functional Dynamic Splint
Inventor: DEHARDE MARK
IPC: A61F5/01
Filed: 1995-03-22
Abstract: A dynamic splint has a bi-directional torsional dynamic tension unit (348) fastened between first and second struts (308,388) to selectively deliver force opposing either extension or flexion. The tension unit (348) is mounted about a pivot post (34) and can be rotated between two positions. In the first position, the power unit is locked relative to the first strut (308) and the torsion spring opposes relative movement of the second strut (388) in a first direction. In the second position, the tension unit (348) is locked relative to the second strut (388). In this second position, the tension unit (348) opposes movement of the first strut (308) relative to the second strut (388), providing torsion in an opposite direction from that of the first position. Self-aligning contour plates (334) on the struts conform to the anatomy and provide a mechanical interlock to bony prominence on the patient's limbs.

Title: Multi-screw, extrusion-compounding machine with modular mixing elements
Inventor: PEREIRA JOSE M
IPC: B29C48/03
Filed: 1995-06-01
Abstract: Multi-screw, extrusion-compounding machines (20) having co-rotating screw assemblies (21, 22) incorporating sets of modular mixing elements (51, 52, 53, 54) of non-symmetrical geometries with relatively large wing tip clearances are disclosed. These sets of non-symmetrical modular mixing elements (51, 52, 53, 54) are removably mountable at any suitable axial locations along their respective rotationally-driven screw shafts (30) for optimizing performance in relationship to particular plastic material and particular additives being compounded. The non-symmetrical geometries provide dynamic wedging pressurization for repeatedly propelling relatively large circumferential flows of the plastic material through large shear clearances. Due to the relatively large shear clearances, the plastic material is mixed at less elevated and more uniform temperatures than usually occurs with use of prior symmetrical kneading blocks or kneading discs. At less elevated temperatures most plastic materials exhibit increased viscosities. Thus, the resultant increased viscosities enable the plastic material to be processed at higher shear stresses for enhancing dispersive mixing, in spite of the relatively large clearances.

Abstract: A glass 1 is irradiated with a focused pulsed laser beam 2 having a peak power density of 106 W/cm2 or more and a repetition rate of 10 KHz or more. The glass 1 irradiated with the laser beam 2 changes its refractive index at the focal point 4. During the laser beam irradiation, the glass 1 is continuously moved with respect to the focal point of the pulsed laser beam 2 or continuously scanned with the focused laser beam 2, so as to form the refractive index changed region (i.e. an optical waveguide 5) with a predetermined pattern. The glass 1 in which the optical waveguide 5 will be formed may be any kind of glass having high transparency.

Title: Safe storage and transportation of sulfur dioxide
Inventor: HAKKA LEO E
IPC: C01B17/60
Filed: 1997-03-25
Abstract: The invention relates to a method of confining sulfur dioxide for storage or transportation under safe conditions.

Inventor: FINDLAY JUDITH M
IPC: A61M25/02
Filed: 1997-05-16
Abstract: This invention relates to an apparatus and method for infusing fluids to and aspirating tissue from an intraosseous site.  The apparatus is comprised of an infusion device coupled to an introducer with a release mechanism that removes the infusion device once it has penetrated the bone a predetermined depth.  As the introducer is withdrawn, the infusion device remains in the bone.  The ball release mechanism and other aspects of the apparatus can be modified to yield different penetration depths.  The present invention also relates to a method and apparatus for locating the site of infusion and for relieving strain and stress on the infusion site.  The template patch uses a key anatomical feature of the bone as a reference point to a target zone for infusion that is located a predetermined distance away from the feature.          The template patch has a tube clamp and a covering that protect the infusion site from external forces.

Patent CA-2223751-A1 (CA)
Inventor: THIBAULT RONALD M
IPC: F24F1/00
Filed: 1996-06-06
Abstract: A ceiling ventilation inlet (10) includes a housing having an air inlet aperture (14), an air outlet aperture (16), and a baffle (20) supported for linear movement adjacent the air outlet aperture (16). A spring (50) is positioned such that the baffle (20) moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle (20) and enters the livestock confinement building in a 360 degree dispersion pattern. The spring (50) causes the baffle (20) to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment, the greater the air outlet area becomes. Since the inlet (10) is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate. Mathematical equations and limiting parameters define the relationship between the geometrical design of the ceiling ventilation inlet and the optimum and acceptable range of properties for the spring (50).
