Patent CA-2049423-A1 (CA)
Inventor: PERLMAN MAIER
IPC: F24D17/00
Filed: 1991-08-16
Abstract: ABSTRACT OF THE DISCLOSURE           A fluid tempering system for use with a standard water heater storage tank includes a heat exchanger which is interposed between the outlet means for conveying heated fluid from the storage tank to a distribution system and the cold fluid inlet means, so that heat energy is transferred between heated fluid exiting and cold water entering the storage tank.  Preferably, the  heat  exchange  is  complete  and water exiting the  heat exchanger in both the inlet and outlet conduits are of about equal temperature.  In order to avoid the water exiting the water heater to the distribution system becoming too tepid, a bypass conduit either in the inlet means or in the outlet means may be provided triggered by a bypass valve located in the outlet conduit.  As a safety feature, a safety shut-off valve is located in  the  outlet  conduit  before  the  distribution  system  to automatically shut-off the conduit where water exiting the system is above a desired maximum temperature.   In this system, the water  in  the  water  storage  tank may  be  kept  at  scalding temperatures since it will be tempered on leaving the storage tank before entering the water distribution system to avoid scalding the user.

Title: Structure and method for programming antifuses in an integrated circuit array
Inventor: GOETTING F ERICH
IPC: H03K19/177
Filed: 1991-11-20
Abstract: M\1223\P\APP001                                  PATENT   STRUCTURE AND METHOD FOR PROGRAMMING ANTIFUSES        IN AN INTEGRATED CIRCUIT ARRAY                      F. Erich Goetting David B. Parlour John E. Mahoney ABSTRACT OF THE DISCLOSURE     This invention provides a structure and method for interconnecting logic devices through line segments which can be joined by programming antifuses.  One of several programming lines can be connected through an interconnect line segment to each terminal of each antifuse in the array.  Interconnect line segments connected to opposite terminals of the same antifuse are connected to a different programming line in order to be able to apply different voltages to the two terminals of the antifuse. An addressing structure selectively connects interconnect line segments to their respective programming lines, and programming voltages applied to the programming lines cause a selected antifuse to be programmed.  A novel addressing feature sequentially addresses two transistors for the line segments to be connected, and takes advantage of a capacitive pumped decoder to maintain the addressed transistors turned on while programming voltages are applied.  The structure also allows for testing of logic devices by applying test voltages to the programming voltage lines and/or sensing logic device output on programming voltage lines.  The structure and method also permit measuring resistance of the programmed antifuses. No separate testing overhead structure is needed.       .
