International Classification:

A01M 120

US Classification:

431321, 43131, 43121

Abstract:

The present invention is directed to a conformable termite bait container capable of being located either against a first substantially planar surface or against a corner defined by the intersection of a second and a third substantially planar surface. The conformable termite bait container preferably comprises a housing which includes a back wall, front wall and side structure operatively connected between the front and back walls. The back wall, front wall and side structure form an interior cavity therebetween capable of storing termite bait. A plurality of openings are located on the housing to allow termites to access the bait locatable therewithin. A first structurally-weakened area is located along the longitudinal length of the back wall, figuratively dividing the back wall into a first back portion and a second back portion. A second and a third structurally-weakened area are located along the longitudinal length of the front wall, the second structurally-weakened area being offset from the third structurally-weakened area a predetermined distance and defining a removably-detachable front wall section. In use, the back wall is capable of being located against the first substantially planar surface.

International Classification:

A01M 1/20

US Classification:

43131

Abstract:

A method for tracking vermin includes causing the vermin to be covered in a non-toxic fluorescent substance which will leave a trail as the rodent enters/exits the human habitation, then examining the habitation with an ultraviolet light to determine the location of the entry/exit point used by the vermin. The fluorescent substance is preferably invisible without the aid of an ultraviolet light. It is also non-toxic to humans as well as animals and is relatively inexpensive. The apparatus for applying the ultraviolet substance is preferably a “bait station” within which an attractive substance is placed and surrounded by the fluorescent substance.

International Classification:

H02K 5/00
H02K 15/04

US Classification:

310 89, 3102541, 29596

Abstract:

A motor stator mounting device includes a plastic motor housing having a cylindrical housing section for receiving the stator. Longitudinal ribs along an inside surface of the housing section are inclined to converge gradually in a distal direction, thus tending to center a stator inserted distally into the housing section. An annular stator retaining member includes a plurality of distally extending centering features. Outside surfaces of the centering features interact with an interior surface of the housing section to center the retaining member as it is inserted distally. Inside surfaces of the centering features interact with a proximal region of a previously inserted stator, such that distal insertion of the retaining member both axially positions and radially centers the stator relative to the cylindrical housing. The retaining member is secured to the housing with a series of sonic welds to positionally fix the stator inside the housing.

US Classification:

417423140, 417423700, 417423300

Abstract:

A low part count blower-motor assembly in a two-part housing which defines fluid inlet and discharge openings for the blower but which is otherwise sealed when assembled. An integrated tubular stator subassembly is fixedly attached to one of the housing parts and projects axially toward the fluid inlet opening. An integrated motor rotor subassembly is also disposed within the housing for rotation about the stator subassembly in coaxial relationship therewith, a part of the rotor subassembly being disposed axially between the stator and the inlet opening in spaced relationship with the opening. A shaft is journaled in the central opening of the tubular stator subassembly and projects axially there from toward the inlet opening and a fluid impeller mounted on the projecting end portion of the shaft receives fluid from the inlet opening. The impeller is also fixedly attached to the part of the rotor which resides between the stator and inlet opening.

Inventors:

David A. Curtis - Torrington CT, US

International Classification:

H02K 15/14

US Classification:

310 42, 29596

Abstract:

An electric motor assembly includes a motor housing having a main body portion with a central plane bisecting the main body portion into an upper portion and a lower portion. The motor housing further includes a first printed circuit board support structure having a plurality of slots and a second printed circuit board support structure having a top surface that is orientationally above at least a portion of the plurality of slots. The motor assembly further includes a printed circuit board having tabs which are configured and arranged to operably coordinate with the plurality of slots to thereby removably retain the printed circuit board at the motor housing and in contact with the top surface of the second printed circuit board support structure.

International Classification:

A01M 120

US Classification:

43131

Abstract:

The present invention is directed to a conformable termite bait container capable of being located either against a first substantially planar surface or against a corner defined by the intersection of a second and a third substantially planar surfaces. In a preferred embodiment, the conformable termite bait container comprises a housing having a front wall, a back wall and side walls operatively connected between the front wall and the back wall, where the front, back and side walls form an interior cavity capable of storing insect bait. A plurality of openings are located on the housing to allow termites to enter and exit the housing and access the insect bait located therewithin. The back wall of the housing is capable of being located against the first substantially planar surface, and in the alternative, the back wall and front wall are capable of being bent substantially in the shape of the corner to allow a first and a second portion of the back wall to be located against the second and the third substantially planar surfaces, respectively, defining the corner. The conformable termite bait container preferably further comprises a back hinge located on the back wall to facilitate the bending of the back wall, and a front hinge located on the front wall to facilitate the bending of the front wall.
