A rotor stator pump includes a rotating helical component and a static helical component. An electric motor is connected to the rotating helical component to drive rotation of the rotating helical component. The rotating helical component and the static helical component are disposed radially inward of the motor rotor of the electric motor.

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.

Ground tape applicator apparatus and method

A road taping machine is configured to unspool road marking tape from a spool and tamp that tape onto pavement via a tamping roller. Tape is cut using a blade assembly, and aligned with several alignment rollers. A pivot arm permits a subset of the alignment rollers to displace, allowing slack in the tape to be taken in during cutting such that taping can occur continuously, despite cuts. The spool is housed on an axle anchored to a support arm that can be actuated between an elevated position for loading, and a depressed position for taping. A taping section of the machine is laterally displaceable relative to a drive section via a displacement plate, to permit taping of laterally remote locations. The machine can support multiple spools, including spools with tape paths that bypass the blade assembly.

A handheld sprayer (′) includes a fluid module (′) mounted to a drive module (′) at a static connection (′) and a dynamic connection (′). The static connection (′) supportably attached the fluid module (′) to the drive module (′). The dynamic connection (′) connects a drive () of the drive module (′) to a pump (′) of the fluid module (′) such that the drive () can power the pump (′) by the dynamic connection (′). The fluid contacting components of the handheld sprayer (′) are in the fluid module (′). The fluid module (′) can be mounted to and dismounted from the drive module (′) by a sliding motion.

A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.

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.

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.
