Title: Discharge valve for dissolved air flotation
Inventor: MAPLES WILLIAM A
IPC: B03D1/24
Filed: 1992-03-10
Abstract: A self cleaning valve (10) for discharge of a pressurized dissolved air flotation aqueous treatment liquid from a high pressure reservoir (76) to a low pressure body of liquid (70) is provided.  The valve (10) includes a discharge head body (12) adapted to be attached to a conduit (18) supplied with pressurized treatment liquid which is provided with a central opening (22) for discharge of a treatment liquid.

Title: Bioreactor for the perfusion culture of cells
Inventor: KNAACK CHRISTIAN
IPC: B01D21/00
Filed: 1993-11-24
Abstract: ABSTRACT OF THE DISCLOSURE   A bioreactor for perfusion culture of suspension cells has an inversely-conical tank which includes a cell culture zone and a cell settling zone disposed annularly relative to the cell culture zone in the upper region of the tank. Thecell settling zone is adjacent to the conical walls of the tank and has a numberof frustoconical lamellar elements. The two zones are separated with a partitionwhich allows the zones to communicate only below the partition. Cell culture medium supplied to the culture zone overflows at the top of the settling zone after having passed through the settling zone between the lamellar elements. Due to the conical shape of the tank and the resulting shape of the settling zone, passages of upwardly increasing cross section are created in the settling zone thus enabling the settling of live cells in the settling zone and their return to the culture zone while the spent medium overflows. The design is relatively easy to scale up.

Title: Unitarily constructed carpet flange with self-closing flap covers for a floor box wiring fitting
Inventor: WUERTZ EMIL S
IPC: H02G3/18
Filed: 1994-03-29
Abstract: A floor box wiring fitting incorporating a novel carpet flange possessing a self-closing flap cover assembly, whereby the fitting is adapted to be cast into a concrete floor of a building for the conductance of electrical power or telecommunication signals between the work spaces of buildings. The self-closing action of the flap covers which are hingedly connected to the flap cover plate structure, the latter of which consists of a carpet flange, is essentially implemented through an angular operative contacting relationship between the wall surfaces of the openings receiving the hinging portion of the flap covers and the contiguous or adjacent wall surface of the flap cover which, in effect, will inhibit the flap covers from being opened or swing upwardly from a closed horizontal position to an acute opening angle greater than about 85°. This acute maximum opening angle measured from the horizontal upper surface of the carpet flange will cause the flap covers to be downwardly closed, in the absence of any plug connectors or receptacles being inserted through the carpet flange, under the action of their own weight or gravity. Also included is novel structure for staking hinge connections of the flap covers in place, and structure for latchingly engaging the flap covers in their closed positions.

Title: High Velocity, Hot Air Dryer and Extractor
Inventor: DEMOORE HOWARD W
IPC: F26B21/00
Filed: 1994-08-02
Abstract: A hot air dryer (10) utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed sheet (S). High velocity air is heated to a high temperature as it flows along a resistance heating element (38) within an air delivery baffle tube (64). The heated, high velocity air pressurizes a plenum chamber (46) within an air distribution manifold (36W). High velocity jets of hot air are discharged through multiple airflow apertures (54) onto the wet ink side of a printed sheet as it moves through a dryer exposure zone (Z). An extractor (40) removes the moist air layer, high velocity hot air and volatiles from the printed sheet (S) and from the press (12). <IMAGE>

Filed: 1993-06-03
Abstract: Combustion apparatus, e.g. for a gas turbine, has at least one catalytic combustion unit (14, 15, 16) having a plurality of through passages of which some are combustion passages (28) having a combustion catalyst on the passage walls and at least some others are bypass preheat passages (29) that are free of catalyst and are adjacent the combustion passages. A first gas stream containing air and fuel is supplied to the combustion and bypass preheat passages; catalytic combustion of the fuel occurs in the combustion passages (28) and heat is transferred through the passage walls to heat the gas in the bypass preheat passages (29). On emergence from the combustion unit (14, 15, 16) the preheated gas from the bypass passages (29) combusts in a down-stream afterburn zone (20). A second gas stream containing air and a variable amount of fuel is supplied to the afterburn zone (20). Where there is more than one combustion unit, larger bypass passages (26) may be provided through the first combustion unit (14) so that part of the first gas stream passses through the first combustion unit (14) without preheating and mixes, in a zone (17) between the first and second combustion units (14, 15), with the gas from the combustion passages (28) and bypass preheat passages (29) of combustion unit (14) to form the gas stream fed to the second combustion unit (15).

Patent CA-2154611-A1 (CA)
Title: Turn Signal Control System
Inventor: HOLLSTEIN JUERGEN
IPC: B60Q1/38
Filed: 1995-07-25
Abstract: A control system controls the vehicle having turn signal lights mounted on both sides of the vehicle in response to deflection of a manually operated turn signal.  The control system includes a control unit which senses vehicle speed and automatically interrupts a flashing mode after a flashing duration which is dependent upon the sensed vehicle speed. The turn signal control unit shuts off the flashing mode in response to deflection of the turn signal lever only for a brief time period and enables the flashing mode in response to deflection of the turn signal lever for a period of time which is longer than a pre-set time period.  The control unit prevents cancellation of the flashing mode in response to a repeat deflection of the turn signal lever only for the brief time period.  The control unit also cancels a first flashing mode associated with deflection of the turn signal lever in a first direction and enables a second flashing mode associated with deflection of the turn signal lever in a second direction in response to brief deflection of the turn signal lever in a second deflection direction.  The control unit maintains operation of the flashing mode in response to deflection of the lever for a period of time longer than a pre-set time period.
