Title: Multi action back water valve system with rat protector
Inventor: PLUDOWSKI ROBERT
IPC: E03F7/04
Filed: 1991-09-23
Granted: 1995-08-01
Abstract: A back water valve system to be installed at  the  entrance of  the  city  sewer  system  into  a dwelling   eliminates   a   series   of secondary conventional  back  water  valves.  The  valve  system includes  a  one-way  check  valve  and  an  opening thereabove partly obstructed by a screen for allowing for free circulation of sewer gases through the valve system.  The screen prevents  the entrance  into the dwelling of small animals such as rats from the city sewer system. A pair of upper flappers each provided with a float are pivotally mounted on the dwelling side  and on  the  city  sewer  side  of  the  opening. Therefore, the one-way check valve prevents spillage into  the  dwelling  of  sewer  back-ups.  The  upper flapper on the city sewer side is adapted to close the opening and its screen also upon sewer back-ups to prevent spillage on the dwelling side of the valve system and also to prevent fouling of the screen. The flapper located on the dwelling side of the opening is adapted to close the opening and its screen when there is a sufficient flow of waste water coming from the dwelling for preventing fouling of the screen. Therefore, the opening and its screen allow for free passage  of  the  sewer  gases  while  protecting  the dwelling against intrusion of rats or other pests. The  one-way  check valve  includes  a  double-hinge flapper which is  normally closed and protects  the dwelling  against  sewer back-ups  while  facilitating the use of fish wires when cleaning the valve system.

Patent CA-2064268-C (CA)
Title: Gas-blast circuit breaker
Inventor: BLATTER JOHANNES
IPC: H01H33/915
Filed: 1992-03-27
Granted: 2003-02-25
Abstract: In a gas-blast circuit breaker, compressed gas is directed through a movable contact maker into a blow-out space, the latter being delimited by a cylinder and a piston which is operatively associated with the movable contact maker. The piston comprises inlet openings which are releasably closed by means of a valve body. At a neck or collar of the piston there is displaceably mounted an actuating element, the latter being reciprocatingly movable between a lower first lock-in position and an upper second lock-in position. The actuating element comprises a nose or lug which, during the closing operation, abuts against an upper stop face or surface, whereby the actuating element is brought into the lower first lock-in position. The valve body thereby moves into the closed position thereof. Towards the end of the opening stroke, a shaft associated with the actuating element comes to bear upon a lower stop face or surface, so that the actuating element is brought back to the upper second lock-in position thereof, whereby the valve body is returned to and retained in its open position. The blow-out space is thus connected with the ambient space during the closing operation and again separated from the ambient space prior to the opening or tripping operation. The driving mechanism of the circuit breaker is assisted during the interruption of relatively high-amperage currents and no additional driving effort is required of the driving mechanism during the closing operation and the interruption of relatively low-amperage currents. The gas-blast circuit breaker thus gets by with a driving mechanism of relatively low operating power.

Title: Porous fiberglass cast system for the setting of broken appendages
Inventor: CRIPPEN WARREN STUART
IPC: A61F13/04
Filed: 1992-04-01
Granted: 1997-04-01
Abstract: A  porous  fiberglass  cast  system  for the setting of broken appendages is herein provided.  The present invention uses  a simplified technique involving a standard fiberglass bandage  typical  in  most  cast  systems.  Fastening strips impregnated  with  a curable resin are sewn or woven in rows along the width of one side and down the length of the other side of the unimpregnated fiberglass bandage.  Upon wrapping the  bandage  to  an  injured  member,  the fastening strips overlap  and  produce  a  cross-mesh.   The  nature  of  the fastening   strips  allows  this  cross  mesh  to  initially stabilize  the  structure during cementing.  After curing is complete, the intersecting points of the fastening strips in the  cross  mesh  provide  a rigidified cross-mesh structure strong  enough  to completely immobilize the injured member.          The   areas  contained  in  the  cross-meshing  between  the fastening  strips,  not  being  impregnated with any kind of resin,  retain  their  porosity  once  the  cast  is  cured.          Consequently,  these  areas  become the avenues for moisture evaporation  and  air  circulation, thereby greatly reducing discomfort to the wearer.

Title: High efficiency induced draft condensing furnace with horizontal plastic vent termination assembly
Inventor: SMELCER JIM C
IPC: F23L17/04
Filed: 1992-08-28
Granted: 1995-09-12
Abstract: A high efficiency fuel-fired induced draft condensing furnace is provided with a horizontal vent termination assembly installed in an exterior wall of a building served by the furnace.  The vent termination assembly, constructed entirely from PVC plastic pipe and fittings, includes a combustion gas vent pipe connected to the furnace's draft inducer fan outlet, horizontally extending through an opening in the wall, and having an open discharge end positioned outwardly beyond the wall.  A larger diameter combustion air inlet pipe circumscribes the vent pipe within the wall opening and forms around the vent pipe an annular combustion air flow passage that is communicated with the furnace combustion air inlet.  A coupling member connected to the  outer  end of the  inlet  pipe has a diametrically enlarged end portion  positioned on the  outside surface of the wall, axially inwardly of the outer vent pipe, and forming an annular inlet to the flow passage between the two pipes.          The outer end of the vent pipe is left uncovered so as to permit direct, unimpeded axially outward discharge therefrom of furnace combustion gases.  In a similar fashion, the enlarged end portion of the coupling member is left uncovered so as to permit direct, unimpeded axially inward entry therethrough of outside combustion air.  Because the open outer ends of the concentric coupling and vent face in the same axial direction, the operating pressure differential across the furnace heat exchanger is substantially unaffected by changes in outside wind velocity and direction.

Filed: 1992-11-03
Granted: 1997-03-25
Abstract: A shift pattern control for a multiple speed ratio transmission wherein an inference-based control overrides the normal shift pattern to automatically achieve manual pulldown operation under conditions for which such operation would be advised and expected. The inference-based control is achieved with a fuzzy logic technique by which vehicle parameters influencing the desirability of manual pulldown operation are measured or estimated, and used to establish an aggregate measure of the overall need for engine braking and downshifting.  In the preferred embodiment, the fuzzy logic parameters include vehicle speed, grade load, engine throttle position, time of braking and time of deceleration.  The parameters are applied to membership functions to indicate the truthfulness of the specified conditions, and logical combinations of the truth indications are formed, weighted to reflect their criticality, and combined to form an aggregate measure of the overall need for pulldown operation.
