Title: Hot water heater controller
Inventor: VANDERMEYDEN TOM R
IPC: F23N1/08
Filed: 1989-02-08
Granted: 1991-11-26
Abstract: HOT WATER HEATER CONTROLLER     ABSTRACT OF THE DISCLOSURE         A  system  is  described  for  use  with  a hot water supply  for  hotels,   apartment   buildings   and  similar multi-unit  structures, which  controls  the  temperature T1 of  water  at  the  outlet of the water tank that circulates past  the  units  and  back  to  the tank, to make the actual temperature T1 close  to  a  desired temperature DTEMP. The desired  temperature  at  the tank outlet, DTEMP, is adjusted according  to  the  measured  temperature T3 of recirculating water  prior to  its reentry into the tank. In cold weather, when T3 decreases  below  a  preset  limit  such  as 105°F, indicating  there  is  a  considerable temperature drop along the  pipeline before water reaches the last unit, the desired tank  outlet  temperature  DTEMP  is  raised  to more than it would  otherwise  be.  As  T3 increases back toward the limit such,  as  105°F,  the  temperature  DTEMP  is  lowered. The system   therefore   automatically  adjusts  for  changes  in temperature drop along the pipeline such as may be caused by seasonal  or  other environmental temperature changes or heavy demand for hot water.

Patent CA-1319646-C (CA)
Title: Fuel cap with tethered anti-splash attachment
Inventor: STEINER RONALD O
IPC: B60K15/04
Filed: 1989-06-21
Granted: 1993-06-29
Abstract: ABSTRACT    A fuel cap has an anti-splash attachment which includes an outer splash-back baffle, an inner foam plug element and a retainer post which supports the outer baffle and inner plug element and tethers them by a releasable snap-on connection to an inner baffle-supporting stem of the fuel cap.  The inner plug element when substantially dry is in a contracted state wherein it is smaller in diameter than the inside diameter of the fuel tank filler neck to which the fuel cap is applied.  An annular gap is then present between the exterior side surface of the plug element and the interior surface of the filler neck, making it easy to insert and withdraw the fuel cap with the anti-splash attachment thereon into and from the filler neck.  However, once the inner plug element becomes wetted and soaked by splashing liquid fuel, it expands to completely fill a cross-sectional region of the filler neck, closing the annular gap and blocking passage of any liquid fuel past the inner plug element while still allowing passage of vapors due to the porous open-cell nature of its material.  The anti-splash attachment can be provided as a separate subassembly allowing retrofitting to pre-existing fuel caps or replacement should the inner plug element wear out over time.

Patent CA-1330150-C (CA)
Inventor: SHAW WILLIAM S
IPC: E03D1/36
Filed: 1989-09-28
Granted: 1994-06-14
Abstract: ABSTRACT OF THE DISCLOSURE    A device for metering the flow of water into the tank and bowl of any currently known tank toilet and providing a positive shut-off of the flow.   When the toilet handle is turned, a linkage rotates a cam to force a stopper from its seat thereby commencing water flow.  Water flows through a flow channel to be directed by a flow nozzle past a water wheel imparting a rotation thereto.  The water wheel is gearably linked to the cam thereby rotating the cam.          When the cam has rotated to position a cam repeat over the stopper stem, the stopper is reseated by the pressure of the water and water flow ceases.  The distribution of flowing water between tank and bowl is controlled by altering the structure of a bowl fill assembly.  The bowl fill assembly and a tank fill tube are attached to the outlet by a right angle manifold.  The amount of water flow permitted is a function of the number of cam notches and flow nozzle size.

Title: High speed differential sense amplifier for use with single transistor memory cells
Inventor: AMIN ALAAELDIN A M
IPC: G11C16/28
Filed: 1989-09-29
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE        A novel circuit is provided which allows a differential sense amplifier to be utilized in conjunction with a memory array comprised of a plurality of memory cells each containing a single transistor.  A differential input signal is applied to the sense amplifier based upon the binary data stored in an addressed memory cell at a rate equal to or greater than the differential input signal available in prior art differential memory cells having two transistors per cell.  This is accomplished by precharging the selected bit line and a reference bit line, and then selecting the word line of the memory cell to be read, while causing the reference memory cell to conduct.  The differential voltage between the selected bit line and the reference bit line is then sensed to determine the state of the data stored in the selected memory cell.  The ratio of currents through the selected bit line and the reference bit line is selected to be other than one, in order to achieve a rapid differential voltage swing, and that rapid reading of the data stored within the selected memory cell.

Abstract: An article suitable for delivering or absorbing liquid includes a substrate carrying a pressure-sensitive porous polymeric material which is capable of retaining at least 10 times its own weight of water or corresponding amounts of other liquids. The porous polymeric material is advantageously a crosslinked homogeneous block material having a dry density of less than 0.1 g/cc and a pore volume of more than 9 cc/g, and may be produced by polymerization of a high internal phase emulsion. In the article of the invention, the polymer may either be dry or contain an included liquid; the dry form is highly absorbent and is useful for mopping up slippages, while the liquid-containing form is useful for delivering treatment liquids, for example, cleaning compositions, to surfaces. The article may take the form of a single- or multi-compartment sachet of paper or nonwoven fabric containing the porous polymeric material.

Abstract: The present invention relates to a method and a device for mixing fluids, in which method the mixing of fluids takes place in a mainly cylindrical mixing vessel by means of a revolving mixing element disposed therein. The invention is characterised by the observation that the most effective manner of maintaining the homogeneity of the settling fluid consists in keeping the flow direction in the vessel as vertical as possible. This is ensured by the agitator shaft having attached thereto paddles/blades (26) by means of which the flow in the vessel is kept columnar at the central section as far as the mixing element (32), which deflects the axial flow via a radial flow into a rising annular flow. <IMAGE>
