Title: Auxiliary battery operation detection circuit
Inventor: FAULK RICHARD A
IPC: H02J7/34
Filed: 1991-09-30
Abstract: AUXILIARY BATTERY OPERATION DETECTION CIRCUIT      A power supply which senses whether a primary battery is discharging to below a predetermined dead battery level or the primary battery has been removed and the system is operating from an auxiliary battery, which has a lower voltage.  When the battery voltage goes below the dead voltage level, the system is in a low power mode and the power supply output voltages are satisfactory, a timer may be started.  If the battery voltage does not drop to the auxiliary battery voltage level within a predetermined time, a shutdown signal is generated and the power supply ceases providing output voltage levels.  In this manner the primary battery can be removed and the system can continue running on the auxiliary battery until a charged primary battery is installed and yet the primary battery discharge rate will be greatly slowed when the primary battery voltage is below a given level and the primary battery is still installed in the system.

Title: Automatically calibrated flow meter
Inventor: MANGAN STEVEN L
IPC: G01F25/00
Filed: 1991-10-08
Abstract: ABSTRACT           This invention describes an apparatus for measuring the rate of  flow of  a  liquid through a pipe  in a vacuum-liquid delivery system in which a first bounded volume for carrying the liquid has an inlet and an outlet and a suction is applied to the outlet. A first pair of electrical contacts interior to the first bounded volume  are  located  in a position where they can be splashed by the liquid as it passes through the bounded volume, thereby causing a varying impedance across the contacts. A second bounded volume having an inlet and an outlet has its outlet connected to the outlet of the first bounded volume. A second pair  of  electrical  contacts  interior  to the  second  bounded volume,  are located therein to be contacted by the liquid when it reaches a predetermined level in the second bounded volume. A processing means  is  electrically  connected  to  the  first  and second  electrical  contacts  for  statistically  estimating  the flowrate based on the varying impedance across the first pair of electrical  contacts  and  then  using  the  measured  flowrate determined from the signal from the second pair of electrical contacts to calibrate the estimated flowrate.

Title: Method of improving the soil anti-redeposition properties of washing detergents and products
Inventor: KRINSKI THOMAS L
IPC: C11D3/384
Filed: 1991-10-31
Abstract: METHOD OF IMPROVING THE SOIL ANTI-REDEPOSITION  PROPERTIES OF WASHING DETERGENTS AND PRODUCTS     ABSTRACT      A detergent composition and method may have the soil anti-redeposition properties significantly and unexpectedly improved by incorporating into the detergent composition an effective amount of an anti-redeposition agent.  The anti-redeposition agent is a casein material which has been modified with an ionic monomer.  Ionic monomers which have been found to be especially effective at improving the anti-redeposition properties of washing detergent compositions are cationic epoxide monomers, cationic acrylate monomers and cationic chlorohydrin monomers.  Anionic or carboxylated casein derivatives have also been shown to be effective anti-redeposition agents.

Title: Sand detector
Inventor: SONTVEDT TERJE
IPC: G01N15/00
Filed: 1990-07-06
Abstract: The invention relates to a method of measuring or detecting an unkown distribution and content of solid material in a flow of liquid and gas, without any calibration. One or several activated probes emitting radiation are used. The radiation is measured by a detector on the outside of the pipe. Each probe emits radiation only to one detector. The probes are mounted apart both lengthwise and across the pipe section. The probes are mounted with an angle .alpha. to the fluid flow, 20· < .alpha. < 60·. Without any signal analyses, the probes will register whether the fluid flow contains solid material if the thickness is reduced 0.1 %. The particle content is calculated with a 0.25 % thickness reduction. The amount of the particles impinging the probes can be calculated.

Title: System for distributing radio telephone signals over a cable television network
Inventor: LAPPINGTON JOHN
IPC: H04M11/06
Filed: 1992-04-30
Abstract: A system for distributing remote telephone traffic between a base station and remote antenna site is disclosed.  The base station and remote antenna sites are connected via a cable television network.  The base station receives from a public telephone network parallel channels of outbound voice signals for radio telephones operating within the cellular areas of the remote antenna sites.   The base station will digitize each of these outbound telephone signals, and time compress them to  fit  in a transmit frame having the length of a standard channel transmit frame of a radio telephone system. The transmit frame is modulated on a subcarrier and applied to the cable television network.  A plurality of remote sites are connected to the cable television network and receive and rebroadcast  digitized  voice  signals  to  radio  telephones operating  within  their  cellular  areas.    Inbound  serial channel data received from a radio telephone is inserted in a serial  receive  data  frame  along with  other channel  data received from other radio telephones operating in this cell. A second subcarrier is modulated with the receive data frame and applied to the cable television network for transmission upstream  to  the  base  station.    The  base  station  will demodulate the inbound receive frame and apply the digitized voice signals to the public telephone network to complete a telephone communication link between the radio telephones and public telephone network.
