Title: Continuously monitored supplemental obstruction detector for garage door operator
Inventor: DUHAME DEAN C
IPC: E05F15/20
Filed: 1992-08-26
Abstract: ABSTRACT         An automatic door operator with a continuously monitored supplemental obstruction detector.   In a first embodiment,  the obstruction detector is a radiant beam obstruction detector that transmits a beam of modulated radiant energy across the door opening.  A safety signal generator  produces  an  active  safety  signal  only  on unobstructed receipt  of  radiant energy by a  receiver.          Failure to receive the active safety signal when the motor is closing the door at least stops the door.  A two wire cable,  which carries both power and the active safety signal, connects the supplemental obstruction detector to the automatic door operator.   Constant activation of a portable transmitter or of a local push button can override the supplemental obstruction detector to close the door.          An alternative supplemental obstruction detector includes a safety edge having a compressible tube disposed on a leading end of the door.  Plural conductors change their conductive state upon compression of the compressible tube.          This embodiment may include a delay upon detection of compression of the compressible tube so that contact with the floor is not detected as an obstruction.

Title: Self-adjusting transformer sling
Inventor: SAULNIER GEORGES
IPC: B66C1/66
Filed: 1993-02-19
Abstract: SELF-ADJUSTING TRANSFORMER SLING                     ABSTRACT OF THE DISCLOSURE    The sling includes a telescopic compensation bar, provided with two pairs of lever arms pivotally mounted to the opposite ends respectively of the compensation bar.  The lever arms pivotally engage at their bottom ends the integral sling hooks of the transformer to be lifted.  Each of the two parallel plates of the telescopic  bar has  an  intermediate  ovoidal  slit,  both  slits slidingly engaged by a transverse shaft.  The shaft depends from a yoke suspended to the hoist gear cable.  The two ovoidal slits are not parallel, but rather disposed in X-shaped fashion.   Hence, during lift, for a smaller transformer width, the compensation bar will automatically retract to a shorter overall length, so as to automatically and continuously maintain the lateral lever arms tightly and firmly against the transformer, whatever the dimensions of the transformer.  Moreover, the greater the transformer weight, the larger the inward bias will be applied by the lever arms against the transformer.

Title: Process to stabilize scrubber sludge
Inventor: BREEN BERNARD P
IPC: C22B1/14
Filed: 1993-04-01
Abstract: A process for stabilizing sludge containing flyash and calcium sulfate formed by a lime or limestone scrubber increases the sludge particles to a size at which leaching of toxic metals from the particles no longer occurs at toxic levels.  The sludge is dewatered and injected into the furnace in a manner to cause the flyash to soften and stick together.

Abstract: A unified and automated system for providing, restoring and optimizing special services is continually aware of the state of all the equipment and facilities in the network. The unified system responds automatically to a request for a special service by 1) designating a circuit required to support the requested special service, 2) identifying network facilities and configurations for implementing the designed circuit, 3) assigning those facilities to the circuit, 4) causing the various equipment providing the facilities to be interconnected  to implement the service, S) verifying the integrity of the special service, and 6) delivering the service to the customer. In accordance with an aspect of the invention, if at any point in the process of providing a special service it is determined that there are no available direct transport facilities in the inventory of network facilities at the level required to provide the special service between the particular points in the network  that must be interconnected to provide the special service, the system will employ procedures for further identifying or developing transport facilities, in accordance with a predetermined hierarchical plan. The identified or developed transport facilities are delivered, as a unit, as a new inventory facility at the required level. In accordance with an aspect of the invention, if an indirect connection is used at any level, the new inventory unit is marked as a candidate  for optimization to be performed in the future. Thereafter the process of providing the special service can proceed as previously described.

Title: Co2 sensor using a hydrophilic polyurethane matrix
Inventor: KAHN SOONKAP
IPC: G01N21/77
Filed: 1993-12-02
Abstract: ABSTRACT OF THE DISCLOSURE     POLYURETHANE MATRIX       The carbon dioxide sensor includes a CO2 sensing matrix formed from a hydrophilic, gas permeable, cross-linked polyurethane.  The polyurethane matrix is formed from a polyurethane pre-polymer mixture which cross links when mixed with an aqueous carbon dioxide buffer solution.  The dye-buffer solution is physically entrapped as a homogeneous dispersion in the polymer matrix.  The matrix is applied to the exposed glass core of an optical fiber, which may first be coated with a primer to allow the polyurethane matrix to bond firmly to the tip of the optical fiber.  The hydrophilic polymeric matrix is preferably coated with a hydrophobic material to help avoid leaching of the dye from the matrix, and to prevent diffusion of hydronium ions into the sensing matrix.  The hydrophobic polymer overcoat may thereafter be cured by heat treatment.  The hydrophobic coating may also contain a light reflective material such as TiO2.
