Abstract: Provided is a metering pump. The metering pump includes a motor and a motor shaft and a pump housing having an inlet port and an outlet port. Encased within the pump housing and engaged to the motor shaft is a piston. The motor shaft imparts rotational movement upon the piston. The metering pump further includes two barrel cam halves engaged to the piston. Between the two barrel cam halves is a cam follower pin which in combination with the two barrel cam halves allows the piston to move in a reciprocating manner upon rotation of the motor shaft. Thus, the piston is capable of moving in both a rotational and reciprocating manner along the same axis.

Abstract: Provided is a push-to-open latch for an oven appliance and other household appliances. The push-to-open latch includes an integrated locking device for locking an appliance door in place and initiate a downstream appliance function such as a self-cleaning function. The integrated locking device includes a rotating cam having a latching slot which engages a pawl. The rotating cam also includes a guiding ramp and a catch surface which may be used to engage a latching finger to lock the cam in place. In addition, the locking device may include a locking slide and a locking slide pin that is actuated by a solenoid to engage the cam. Once the appliance door is locked, one or more switches send a signal to the appliance controller to activate the downstream function.

Abstract: An actuator assembly is provided for converting rotation into linear displacement including a linear fluid dispensing tube for linear displacement. Hemispherical lugs are monolithically formed on the linear member. A primary gear includes a central bore having helix grooves formed into a surface of the central bore. The helix grooves receive the hemispherical lugs so that each helix groove mates with a respective hemispherical lug to reduce friction, so that hemispherical lugs slide smoothly within the respective helix grooves. Linear projections are formed on the exterior surface of the dispensing tube and extend longitudinally along the dispensing tube. A projecting portion has an aperture for receiving and guiding the dispensing tube through the linear displacement. Mating grooves are formed on an interior of the projecting portion for receiving and guiding the linear projections, thereby preventing the dispensing tube from rotating during travel.

Abstract: Provided is a door latch including a latch mechanism, secured to an appliance such as a self-cleaning oven, which locks an appliance door to the appliance. The latch mechanism includes a latch bracket mounted to a surface of the appliance. A latch hook is mounted within the latch bracket for reciprocal movement between locking and unlocking positions. The latch hook pivotally engages a receptacle mounted on the door, to lock the door to the appliance. A flexible cable is retained inside a flexible conduit. A first end of the flexible cable is connected to the latch hook for displacing the latch hook into the locking position for pivotal engagement with the receptacle. An electric actuator is connected to a second end of the flexible cable for producing operative movement of the flexible cable within the flexible conduit to displace the latch hook between the locking and unlocking positions.

Abstract: A latching assembly uses a flat sheet metal chassis with electrical switches, an electrical motor driving a cam, a push rod, a hook, a spring, and various actuators/levers. When a first actuator/lever is moved by an outside force, a circuit connection may be opened or closed depending upon the configuration of the electro-mechanical system. This will generate a signal which will allow current to flow to a motor. The motor will, in turn, drive the cam which will push a second actuator/lever to move and cause a hook to move from a first, non-latching position to a second, latching position. The assembly is useful for latching an oven or other appliance door when operating at high temperature.

Abstract: A portable welder includes a welder housing. The housing has front and rear vertical end surfaces and left and right side surfaces. The housing further has a horizontal top surface extending forward from the rear surface. An inclined surface faces upward and forward and extends from a front end of the top surface to a top end of the front surface. A front post, equidistant from the side surfaces, extends upward from the inclined surface. A rear post, equidistant from the side surfaces, extends upward from the top surface. A handle, spaced above the top surface, extends from the front post to the rear post. The welder is configured for a user to carry the welder by lifting the handle such that the housing is suspended from the handle by the posts.

Abstract: An apparatus includes a wall defining an opening. A first bracket is connected to the wall and defines a first channel. A second bracket is located across the wall opening from the first bracket and defines a second channel. A hinge connects the second bracket to the wall such that the second bracket can pivot from a first position in which the second channel is open toward the wall opening to a second position in which the second channel is open toward the first channel. The brackets are configured to retain the lens in an installed position in which the lens extends across the wall opening, the first bracket captures a first end of the lens, the second bracket is in its second position, and the second channel captures a second end of the lens.

Abstract: A welder comprises a source of electrical welding current. A housing houses the source and has front and rear walls and a top wall. A control device, for controlling a condition of the welder, is located along the top wall. A rear wheel is attached to the housing and has a portion located both rearward and downward from the housing. This enables the welder to pivot about the rear wheel between an upright position and a lying position. A front wheel and a foot are attached to the housing. In the upright position, the front and rear wheels engage the floor to support the housing above and spaced from the floor. In the lying position, the rear wheel and the foot engage the floor to support the housing above and spaced from the floor.

Abstract: A selective venting spray assembly is disclosed which includes a sprayer for dispersing a spray of liquid and a spray shaping air flow. An aircap is attached to the sprayer for atomizing and directing the spray. The aircap includes one or more spray shaping passages for receiving the airflow and directing it against the spray to alter the shape of the spray. A flow channel assembly is provided to fluidly connect the aircap to the sprayer. The flow channel assembly includes a flow passage selectively switchable between a first position where airflow is admitted from the sprayer to the spray shaping passage, and a second position where the airflow is diverted to a vent, to produce a non-shaped spray without creating damaging back pressure within the sprayer.
