Patent CA-2129993-A1 (CA)
Title: Soft tissue augmentation material
Inventor: HUBBARD WILLIAM G
IPC: A61L27/46
Filed: 1993-02-05
Abstract: A permanent, biocompatible material for soft tissue augmentation. The biocompatible material comprises a matrix of smooth, round, finely divided, substantially spherical particles of a biocompatible ceramic material, close to or in contact with each other, which provide a scaffold or lattice for autogenous, three dimensional, randomly oriented, non-scar soft tissue growth at the augmentation site. The augmentation material can be homogeneously suspended in a biocompatible, resorbable lubricious gel carrier comprising a polysaccharide. This serves to improve the delivery of the augmentation material by injection to the tissue site where augmentation is desired. The augmentation material is especially suitable for urethral sphincter augmentation, for treatment of incontinence, for filling soft tissue voids, for creating soft tissue blebs, for the treatment of unilateral vocal cord par-alysis, and for mammary implants. It can be injected intradermally, subcutaneously or can be implanted.

Patent CA-2140726-A1 (CA)
Title: Lancing Device with Automatic Cocking
Inventor: PURCELL D GLENN
IPC: A61B5/15
Filed: 1995-01-20
Abstract: A firing burton is loaded with a firing button spring and a drive spring connecting the firing button to a plunger. As the user presses the firing burton and compresses the firing burton spring, the user also moves the plunger until the plunger engages a latching mechanism. The latching mechanism holds the plunger in a latched position, and, as the user continues pressing the firing button, the user compresses the drive spring connected to the plunger. Before firing, the drive spring is compressed enough such that the biasing force of the drive spring is sufficient to cause the plunger to strike and drive a lancet into the user's finger. At that point, the pressing of the firing button causes the lancing device to fire. The plunger unlatches and drives the lancet into the user's finger under the biasing force of the drive spring. At firing, the firing burton spring is compressed, and, once the user releases the firing button, the firing button spring returns the plunger and the firing button to the cocked position under the biasing force of the firing burton spring.

Title: Teaching aid for spinal mobilization and manipulation therapy
Inventor: KUMAR SHRAWAN
IPC: G09B23/28
Filed: 1995-05-02
Abstract: A teaching aid for spinal mobilization and manipulation therapy is described which includes a first support on which is mounted a spinal model.  A second support underlies the first support.  A third support underlies the second support. The third support has a cavity into which the second support is telescopically received.     Telescopic movement of the second support relative to the third support occurs when a force is applied to the first support.   A load sensor is disposed between the first support and the second support whereby a force with which the first support is pressed toward the second support is measured.  A plurality of springs are disposed between the second support and the third support to provide  resistance  to telescopic  movement  of  the  second support relative to the third support.  A displacement sensor is secured between the second support and the third support whereby the displacement of the second support relative to the third support is measured.  A microprocessor is linked to the load sensor and the displacement sensor.  The microprocessor is programmed to receive signals from the load sensor and the displacement sensor, convert the signals into values,  and compare the values as to the amount of displacement occurring and the amount of force being applied to a therapeutic range of values.  Human readable feedback is provided as to whether the measured values for force and displacement are within the therapeutic range.

Title: Method and system for remediation of groundwater contamination
Inventor: VIGNERI RONALD J
IPC: B01F15/04
Filed: 1994-02-10
Abstract: A method for remediating a hydrocarbon-contaminated region of a subterranean body of groundwater (10) to destroy or reduce the initial concentration levels of hydrocarbon contaminants. A plurality of mutually spaced wells (12, 14, 16, 18) are provided which intersect the groundwater (10) region. A treating flow of acetic acid is provided from one or more of the wells into the groundwater region, to establish acidic conditions. A turbulent flow of an aqueous solution of ferrous ion into the groundwater (10) region is generated for mixing with the acidified groundwater (10), thereby providing a catalyst for disassociation of hydrogen peroxide. A treating flow of hydrogen peroxide solution from one or more of the wells (12, 14, 16, 18) into the groundwater region is then provided, so that the hydrogen peroxide may undergo a Fenton-like reaction in the presence of the acidic conditions and ferrous ion to generate hydroxyl free radicals for oxidizing the contaminants. An apparatus system for practising the method is also disclosed.

Title: Process and apparatus for the continuous production of wood boards
Inventor: BIELFELDT FRIEDRICH B
IPC: B27N3/24
Filed: 1995-11-14
Abstract: The invention provides a process and apparatus for the continuous production of wood boards, but primarily for the production of chip and fibreboard, in which a mat of material-to-be-pressed, compounded with binders, is formed from an initial mixture of chips and/or fibres at a dispersal station on a continuously moving dispersal belt, and this mat of material-to-be-pressed after precompression and preheating between the dispersal station and the main pressing area, is brought into final form and hardened with application of pressure and heat in the main pressing area.  The invention consists in that moisture in the mat of material-to-be-pressed at the entry into the main pressing area is lower than the moisture in the initial mixture during the dispersal of the mat of material-to-be-pressed, a portion of the moisture passed to the mat of material-to-be-pressed during dispersal having been withdrawn from the mat by preheating by means of hot air.  The equipment is designed as a preforming press with a preheating and moisture conditioning device, which is enclosed by a continuously operating upper and lower steam-permeable wire mesh belt, preferably a woven belt, and forms a closed system, comprising several processing segments, consisting of a precompression press, a hot air heating and drying device, and, if required, a steam sprinkler for the pressing surfaces of the mat of material.
