Filed:

Aug 4, 2011

Appl. No.:

13/198193

Inventors:

Bruce William Grindeland - Franklin WI, US

International Classification:

H05K 7/00

US Classification:

361622

Abstract:

A Motor Control Center Subunit(s) (bucket(s)) with compartmentalized disconnect associated with a distinctly separate load compartment, consisting of multiple compartments arranged so as to allow service of the load compartment without exposure to line voltages. The invention removes the energized components from the associated loads they are feeding, thereby greatly reducing the health risks and decreasing the cumbersome nature of legally necessary methods and procedures that a person working within such a compartment would currently have to ascribe to. A key feature/distinction of this invention is that the disconnecting devices is remote mounted from the load controlling components, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its conductors) within the load compartment that remain energized by line voltage.

Inventors:

Bruce William Grindeland - Franklin WI, US

International Classification:

H02B 1/00

US Classification:

361605

Abstract:

A modular pump control panel assembly consisting of multiple compartments arranged so as to allow service of each individual compartment without exposure to line voltages while still maintaining operation of the pumping system. The assembly includes a plurality of motor controller compartments each including a lockable handle operator that that is interlocked with its corresponding compartment door. The handle operators are mechanically connected to remote disconnecting devices via flexible cables or mechanical linkage. A key feature/distinction of this invention is that the disconnecting devices are not located in their corresponding motor controller compartments, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its supply conductors) within the motor controller compartment that remains energized by line voltage.

Inventors:

Bruce William Grindeland - Franklin WI, US

International Classification:

F16P 3/20

US Classification:

307328

Abstract:

An electrical disconnect assembly with separate disconnecting device compartment, such that safety handle mechanism does not provide access to the disconnecting device or any energized parts or conductors consisting of multiple compartments arranged so as to allow service of the load compartment without exposure to line voltages. The assembly includes a plurality of compartments with the load compartment having a lockable handle operator that that is interlocked with its corresponding compartment door. The handle operators are mechanically connected to the disconnecting devices via flexible cables or mechanical linkage. A key feature/distinction of this invention is that the disconnecting devices is remote mounted from the overcurrent protective device, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its conductors) within the load compartment that remain energized by line voltage.

Inventors:

Bruce William Grindeland - Franklin WI, US

International Classification:

H05K 7/00

US Classification:

361724

Abstract:

A Compartmentalized Pump Termination Enclosure for Multiple Pumps with Integral Load Disconnects assembly consisting of multiple compartments arranged so as to allow service of each individual load side compartment without exposure to line voltages while still maintaining operation of the other pumps within the pumping system. The assembly includes a plurality of load side disconnect compartments each including a lockable handle operator that that is interlocked with its corresponding load side compartment door. The handle operators are mechanically connected to the disconnecting devices via flexible cables or mechanical linkage. A key feature/distinction of this invention is that the disconnecting devices have their line and load side compartments segregated, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its conductors) within the load side compartment that remain energized by line voltage. The handle operator, when OFF, grants access to the load side compartment only.

Bruce Grindeland - Franksville WI, US

Abstract:

A system is presented that monitors the condition of a plurality of pumps in a system of pumps using a remote telemetry unit (RTU) associated with each pump. The RTUs have a sensor configured to detect when a power failure occurs and a power backup system that includes at least one capacitor that is configured to power the RTU in response to a power failure long enough for the RTU to transmit a power failure signal to a computer system that monitors the status of the pumps. The computer system initiates a delay timer in response to receiving a power failure signal and transmits a power failure signal to a technician if a power up signal is not received within the time set by the delay timer. Using capacitors instead of batteries allows the RTU to be sealed within a container and/or a potting compound.
