6/189377

Inventors:

Kenneth W. Scott - Coronado CA

International Classification:

F16L 3320

US Classification:

G05D 2300

US Classification:

219330

Abstract:

A water heater control system is provided to lower the temperature to which hot water is heated during periods of low use, and raise the temperature back up during periods of peak demand. The unit described herein is adapted for use on a recirculating hot water system used in apartment buildings and includes a first thermoswitch disposed on the outflow pipe from the hot water tank which feeds this recirculating system. This pipe is hotter during periods of low use because the heater is adequate to provide continuous supply of very hot water which has not been drained by tenant use. Thus this thermoswitch is directly wired to a thermostat control to reduce the heater temperature when the thermoswitch is hot. A second switch is mounted on the cold water inflow supply pipe into the water heater, this thermoswitch being wired in series with the first thermoswitch, this switch being closed only when it is cooled, similar to the first thermoswitch, so that when the inflow supply pipe is cool due to high usage and thus continuous input of cold water, the second thermoswitch closes, which permits the first thermoswitch to control the system. During quiescent periods of low use, the inflow warms due to conduction from the hot water tank, thus opening the second thermoswitch and making the first switch ineffective.

A. O. Smith Corporation - Milwaukee WI

International Classification:

H02P 602

US Classification:

318254

Abstract:

A commutated brushless dc motor includes a detector which senses the zero crossings of the unenergized winding. A timing system includes a reference capacitor coupled to the detection unit and charged to a voltage proportional to zero crossing time. The voltage is compared to a capacitor charged from a constant current source. At a percentage level of the reference capacitor, a commutating pulse is applied to a winding commutating circuit. The incoming pulses drive a counter and actuates a programmed decoder which generates output signals for commutation of the windings and selection of the next unenergized winding. The detector is selectively connected to sense the induced voltage in the unenergized winding. To start the motor, a separate charging circuit creates initial pulses to energize the windings and accelerate the motor. At a given speed, the zero crossing circuit is enabled.

Inventors:

Kenneth W. Scott - Coronado CA

International Classification:

F23N 108
F24H 100

US Classification:

236 20R

Abstract:

A water heater control system designed to conserve energy, in part by anticipating hot water demand as a function of usage, utilizes refined design features to effectively automatically switch the water heater's thermostat between a high and a low setting in response to actual use of hot water and the heat of the water at the moment. The basic purposes of the invention are first, the prevention of the system from switching into the "high" mode when in fact adequate hot water is still present in the tank, and second, the reduction of the length of the burner firing time at times when a long burn is not necessary. These features include a specialized heat sensor switch which permits the trigger temperature of the switch to follow the seasonal temperature of the incoming water, also a stack gas switch for further refining the system's function. Remote control and a special mounting means are also included in the refined control system.

International Classification:

H02D 318

US Classification:

318803

Abstract:

A bridge between the inductor and the capacitor of the DC-Link of a voltage-source inverter AC motor drive includes a GTO (or transistor) device used for forced-commutation in the regenerating mode, while the current is controlled ON and OFF according to a duty-cycle defined by an hysteresis circuit to hold the current flowing into the inductor to a magnitude which establishes a boost on the capacitor voltage, so that in the motoring, as well as the regenerating mode of operation, the voltage of the capacitor is kept constant and higher than upon the converter output.

Appl. No.:

Inventors:

Kenneth W. Scott - Coronado CA

International Classification:

E06B 938

US Classification:

1601782

Abstract:

A control is provided for louver blinds of the kind that hang vertically, although it would work for horizontally extended blinds and any other curtain or window cover in which both a double chain and a double cord or their equivalents were used. The control provides longitudinal channels through which the chains and cords pass, and are controlled by a cam and release bar arrangement to grip one of the cords, and three plungers to grip the other cord and two chains and exit the opposite side of the body of the control so that the control is easily gripped in one hand with the release bar pressed by the fingers and the thumb pressing a selected one of the buttons, or vice versa, so that all blind movements are made by pulling the control down, and lifting it back up in idling mode to pull down again, if necessary.

International Classification:

F24H 100

US Classification:

219334

Abstract:

A water heater control system for controlling the thermostat setting on a water heater which senses the temperature on an outflow line from the water heater and energizes a control for lowering the thermostat setting during periods of low flow demand and raising the thermostat setting during periods of high demand, thereby reducing overall required heating energy.
