Apparatus for distributing cement
There is a hopper having a substantially closed interior space that is configured to receive a binder, a fill assembly that is configured to be in fluid communication with the interior space of the hopper, and an exit port. Secured to the hopper is a base with at least one carrier. A pneumatic pump is secured to the hopper. An ingress pipe is secured to be in fluid communication with the pneumatic pump. A valve housing is secured to the ingress pipe and the exit port of the hopper. A valve is secured within the valve housing. An egress pipe is secured to the valve housing, and a spreader bar is secured to the egress pipe.
BOOM HOSE APPARATUS
A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

METHOD AND APPARATUS FOR DISTRIBUTING CEMENT
A method is provided. First and second carriers of a base are engaged with first and second tines of a fork of a loader, and the distribution box is lifted. A pneumatic pump is actuated with a hydraulic motor, and air is moved from the pneumatic pump through an ingress pipe to a valve housing and from the valve to a spreader bar through an egress pipe. A valve is actuated so as to mix the binder exiting the hopper with the air. The loader is moved along an unfinished surface while distributing the binder through the spreader bar onto the unfinished surface.

TRENCH FILLING MACHINE
A trench filling machine having a hopper supported below a tub containing trench filling material. The hopper is configured to deposit the trench filling material into a narrow trench formed in the ground surface. The hopper is attached to a frame of the machine using a suspension system. The suspension system includes a shock absorber configured to raise and lower the hopper in response to shifting of the machine's trajectory. The suspension system further permits limited lateral movement of the hopper in response shifting of the machine's trajectory or variations of the path of the trench.

Hydraulic system with suction/return filter
The invention relates to a hydraulic system, preferably for piloting and actuating a two-cylinder thick matter pump. The hydraulic system comprises a tank (68) for receiving hydraulic oil, a primary circuit having at least one hydraulic consumer (AH, MH) which has at least one primary pump (36, 38, 61, 70), which is loaded with hydraulic oil via a first suction line (42), and is connected on the outlet side to at least one first return line, and which has a suction/return filter (40) which communicates with the first suction line (42) on the outlet side and is loaded on the inlet side with return oil from the at least one return line. A special feature of the invention consists in that the first suction line (42) communicates with the tank (68) via a separate replenishing suction line (86) and a suction filter (66), wherein a replenishing suction valve (88) which is preloaded in the direction of the suction filter (66) is arranged in the replenishing suction line (86).
