Abstract: A handheld sprayer (10?) includes a fluid module (12?) mounted to a drive module (14?) at a static connection (16?) and a dynamic connection (18?). The static connection (16?) supportably attached the fluid module (12?) to the drive module (14?). The dynamic connection (18?) connects a drive (84) of the drive module (14?) to a pump (24?) of the fluid module (12?) such that the drive (84) can power the pump (24?) by the dynamic connection (18?). The fluid contacting components of the handheld sprayer (10?) are in the fluid module (12?). The fluid module (12?) can be mounted to and dismounted from the drive module (14?) by a sliding motion.

Abstract: A ground tape applicator is configured to apply adhesive tape to ground surfacers. The ground tape applicator includes a plurality of rollers that guide the adhesive tape to the ground surface and apply the adhesive tape to the ground surface. The ground tape applicator includes a blade configured to engage with the adhesive tape to cut the adhesive tape to a desired length.

Abstract: An extendable bag roller for supporting a bag of material during removal of the material from the bag includes a bag support having a curved surface configured to support the bag of material on the curved surface and a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag. The bag support includes a base defining a first portion of the curved surface of the bag support and an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes.

Abstract: A disclosure pertains to a reciprocating pump configured for pumping fillers or aggregates or cementitious material and the like.

Abstract: A mobile spray dispenser comprises a fluid circulation system and a heating unit. The fluid circulation system has a motorized pump capable of circulating fluid from a fluid reservoir in a high-pressure spray mode and a low-pressure recirculation mode, and of providing the fluid to a sprayer. The motorized pump draws lower power in the low-pressure recirculation mode than in the high-pressure spray mode. The heating unit is disposed within the fluid circulation system to heat the fluid to a target temperature, and comprises a primary heater and a boost heater. The primary heater is configured to be active during both the high-pressure spray mode and the low-pressure recirculation mode. The boost heater is in fluid series with the primary heater, and is configured to be active only during the low-pressure recirculation mode.

Abstract: A heated fluid line comprises an inner tube, an outer sheath, and a heating element. The heating element disposed between the inner tube and the outer sheath. The heating element comprises an interior core formed of a first metallic material, and an exterior jacket formed of a second metallic material. In one embodiment, the heating element is wrapped around the inner tube and has a round cross-section. In another embodiment, the exterior jacket is non-reactive and resistant to water corrosion, and the outer sheath is moisture impermeable.
