Title: Toilet flush control device case #2
Inventor: LAZOWSKI ANDREW
IPC: E03D1/35
Filed: 1987-03-11
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE A patented valve control for use in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuating lever and a chain connecting the lever to the valve for opening the latter, includes an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float on the arm biasing the valve to the open position when the tank is full and biasing the valve to the close position when the tank is empty, and a drainable container on the arm biasing the valve open when the latter is open and biasing the valve closed when the latter is closed.  The amount of water discharged through the outlet during each flushing operation can be reduced by mounting a flush control device on the arm of the valve control.  The flush control device is a rectangular parallelepipedic body with a groove in one side thereof for mounting the body on the arm.  A slot extends into the groove from one end of the body for facilitating mounting of the body on the arm.  The body changes the turning moment on the arm to close the valve before all of the water has been discharged from the tank.          Thus, the quantity of water discharged from the tank to the toilet bowl during each flushing operation can be reduced.

Title: Method for screening an expression cdna clone bank for the detection of polynucleotides
Inventor: CURTISS ROY III
IPC: C12R1/19
Filed: 1989-12-04
Granted: 1997-09-02
Abstract: The invention encompasses methods of maintaining desired recombinant genes in a genetic population of cells expressing the recombinant gene. The methods utilize mutant cells which are characterized by a lack of a functioning native gene encoding an enzyme which is essential for cell survival, wherein this enzyme catalyzes a step in the biosynthesis of an essential cell wall structural component and the presence of a first recombinant gene encoding an enzyme which is a functional replacement for the native enzyme, wherein the first recombinant gene cannot replace the defective chromosomal gene.  The first recombinant gene is structurally linked to a second recombinant gene encoding a desired product. Loss of the first recombinant gene causes the cells to lyse when the cells are in an environment where a product due to the expression of the first recombinant gene is absent.  The invention also encompasses methods of creating and isolating mutant cells with the above characteristics.  The cells of the invention are useful for commercial production of desired products, for components of vaccines for immunizing individuals, and for release into the environment.

Abstract: TITLE            INSTRUMENT TO MEASURE THE ERRORS     OF APPARENT POWER METERS                         INVENTORS         Réjean J. Arseneau Piotr S. Filipski John J. Zelle ABSTRACT OF THE DISCLOSURE     An instrument to determine, under actual field condi-tions, which type of VA demand meters are most appropriate for a particular consumer.  The type of electrical load that the consumer places on an electrical supply system can introduce harmonics and phase distortion in the system resulting in VA meters producing incorrect readings.          These VA meters are intended to measure the true apparent power S which is defined as S = Vrms X Irms but, are generally designed to operate according to one of the following approximate formula:     (1)     S' =  Vrect X Irect X (1.11)2 and (2)     S" =   where P is the active power and Q the reactive power.     The instrument contains a circuit to measure the rms values of the voltage and current waveforms from which the true apparent power S can be obtained as well as circuits to determine the value S' and S" according Abstract (Cont.) to the two approximate formula from which error signals e1 and e2 can be determined to  indicate the type of errors that can be expected from VA meters designed to operate according to the two approximate formula and, as a result, determine which type of VA meter is most appropriate for a particular consumer.

Abstract: ABSTRACT      A silicon-based sensor (10) includes a substrate (20), a sensor element (12), and a protective diaphragm (22a) mounting and covering the sensor element (12).  The diaphragm (22a) is a  silicon layer (22) which, in a preferred embodiment, includes an etch-stop dopant.  The etch-stop layer (22) is sealed to the substrate (20) so that the layer (22) covers and mounts the sensor element (12) to the substrate (20).  The sensor (10) is fabricated by forming a trough area (33) in a surface (32) of a silicon block (30) (e.g., a silicon chip or wafer), treating the trough area (33) with an etch-stop dopant (e.g., boron), depositing a sensor element (12) onto the doped trough area (33), sealing at least the periphery of the doped trough area (33) to a surface of a substrate (20) (e.g., glass) so as to encapsulate the sensor element (12), and then etching away undoped regions of the silicon block (30) so that the doped trough area (33) remains as a protective diaphragm (22a) sealed to the substrate (20) and covering the sensor element (12).  It is also possible to form a bonding pad (16) on untreated (e.g., undoped) discontinuous regions (22c) of an otherwise etch-stop treated trough layer (34) so that when etched, the bonding pad (16) is exposed to permit interconnection with electronic circuitry, yet the etch-stop treated layer (22) remains so as to mount the bonding pad (16) to the substrate.
