Abstract: A hot water system for connection to a water supply and a local hot water usage system, comprising a plurality of series-connected reserve tanks and demand tanks for receiving water from the water supply, heating the received water to a desired temperature within the reserve and demand tanks, and supplying the heated water to the local hot water usage system as it is demanded. A controlling device is provided for sequencing the operation of the reserve and demand tanks relative to peak power consumption hours and off-peak hours. Specifically, each of the tanks is provided with one or more thermostats which are selectively enabled or disabled by the controlling device at predetermined times. The one or more thermostats are, in turn, connected to one or more heating coils or maintenance coils. The reserve tanks and demand tanks may be operated under control of the controlling device in any of three modes, as follows: maintenance mode, enable mode, and disable mode. In maintenance mode, the water is maintained at a desired temperature either via enabling a thermostat which is connected to a low-power maintenance coil and disabling the heating coil thermostats, or via cycling power through the heating coil thermostats if no maintenance coil is provided. In enable mode, the heating coil thermostats are enabled so that the water temperature may be increased in a tank via activation of the heating coils under thermostat control, and if a maintenance coil is provided then the maintenance coil thermostat is disabled. In disable mode, the heating coil thermostats, and associated heating coils, are disabled to minimize power consumption. If the tank is provided with a maintenance coil, then the maintenance coil thermostat and associated maintenance coil are also disabled when the tank is operating in disable mode.

Inventor: MIRZA M ATHER
IPC: A61B17/34
Filed: 1993-12-01
Abstract: ABSTRACT OF THE DISCLOSURE A method of implementing an endoscopic surgical procedure on a patient, and more particularly, a novel and unique technique of performing a uniportal palmar subligmentous endoscopic carpal tunnel release. Moreover, also disclosed is a unique endoscopic surgical instrument adapted to be employed in the implementation of the foregoing method of endoscopically effecting the carpal tunnel release. This surgical procedure only requires the formation of a single and relatively small entry portal or incision in the palm proximate the distal side of the flexor retinaculum, thereby reducing any postoperative symptoms of the patient with only a cosmetically appealing scar formed on the palm, while eliminating the need for a second portal or incision proximate the wrist of the patient. Moreover, the endoscopic instrument employed in implementing the inventive method utilizes a unique cutting device which is mounted on a scope insertable through a cannula which has been initially inserted to extend beneath the flexor retinaculum from the distal side of the flexor retinaculum.
