Patent CA-2098951-A1 (CA)
Inventor: MARLATT WAYNE G
IPC: E06B9/84
Filed: 1993-06-22
Abstract: A hold and release mechanism for a fire door spring tension adjusting wheel  includes  a  finger which  is retractable when the adjusting wheel is rotated in a direction to increase the tension of the door spring but remains in engagement with a notch on the periphery of the adjusting wheel to prevent rotation of the adjusting wheel in the other direction as urged by the spring tension.  The finger is held within a bore in a block which is pivotably mounted to the plate supporting the adjusting wheel.  A toggle arrangement coupled to the holding chain and the block keeps the finger engaged in the  notch.    When  tension  on  the  holding  chain  is released,  the block is allowed to pivot so that the finger disengages from the adjusting wheel, which is then allowed to rotate under the urging of the fire door spring.  This arrangement permits an operator to adjust the spring tension without requiring that the tension applied by the holding chain be relieved.

Title: Method and composition for revitalizing scar tissue
Inventor: BERG RICHARD A
IPC: A61K47/42
Filed: 1993-08-12
Abstract: ABSTRACT OF THE DISCLOSURE   In accordance with the present invention, a method is disclosed for the remediation of scar tissue in a human or an animal by introducing into the scar tissue or into tissue adjacent the scar tissue a remedial composition comprising a bioactive material selected from naturally occurring growth factors, synthetic growth factors, active peptide segments of naturally occurring and synthetic growth factors, and mixtures thereof. Typically the remedial composition includes a biodegradable or non-biodegradable support matrix material to provide for timed release of the bioactive material. Preferably, the support matrix material is biodegradable and is selected from the group consisting of collagen, glycosaminoglycan, gelatin, albumin, hyaluronic acid, heparin, oxidized cellulose, dextran, polyglycolic acid, polylactic acid, polyanhydride and mixtures thereof. Most scar tissue, particularly in human beings, is very dense and is difficult for the remedial composition described above to penetrate. To render the scar tissue less dense and to spatially expand the scar tissue fibrils, it is preferable to introduce into the scar tissue a softening, expanding composition as well as the remedial composition containing the bioactive material. The softening, expanding composition can be introduced simultaneously with introduction of the remedial composition; however, it is preferable that the softening, expanding composition be introduced prior to the remedial composition. A preferred softening, expanding composition includes at least one dried collagen-comprising polymer, at least one polymer hydrogel and a non-aqueous liquid carrier material.

Abstract: INTELLIGENT  POSITION  TRACKING                 ABSTRACT OF THE DISCLOSURE     A constellation (12) of satellites (14) which are distributed around the earth serves as a communications infrastructure (12) that supports autonomous position determination and reporting of that position to a remote location (28).  Subscriber units (30) are remotely programmed to activate upon the occurrence of an activation event (120) and to record an itinerary (244).  In an intelligent tracking embodiment, reporting of position occurs only when a current position deviates from the itinerary (244).  If subscriber units (30) can engage in activities (194) which lead to determining their position, they cooperate with the infrastructure (12) to determine their positions.  To determine position, location pulses may be transmitted on a regular schedule (106, 144).  Location pulses are transported between a fast moving satellite (14) and a subscriber unit (30). Relative movement causes different location pulses to have different propagation delays and Doppler characteristics.  By analyzing changes in propagation delays and Doppler characteristics, a procedure (170) determines a position for a subscriber unit (30).

Title: Method and apparatus for extended time delay of the detonation of a downhole explosive assembly
Inventor: KLEIN DIETER
IPC: F42D1/04
Filed: 1993-10-20
Abstract: ABSTRACT OF THE INVENTION    A method and apparatus adapted to provide a time delay between the hydraulic actuation of the firing head assembly by fluid pressure and the detonation of a downhole explosive device used in subterranean wells, such as a perforating gun.   In a preferred embodiment, the firing head assembly can be quickly and easily connected in a tubing string intermediate the ported sub and the perforating gun or other explosive device.   In one preferred embodiment,  the hydraulically-actuated firing head assembly is provided with five combustible columns which are generally coextensive.  When the fluid pressure applied to the firing head assembly is sufficient to actuate the firing head assembly,  the actuation mechanism,  such as a firing piston, initiates  a  combustive  reaction  in  one  end  of  the  first combustible column.  When the combustive reaction reaches the other end of the first combustible column, it is communicated to one end of the second combustible column.  The second combustible column likewise combusts and communicates the combustive reaction to one end of the third combustible column.  This cycle continues through the third, fourth and fifth combustible columns.  When the combustive reaction reaches the end of the fifth combustible column, the combustive reaction is communicated to and detonates the perforating gun or other downhole explosive device.
