Abstract: An intake nozzle fits onto the suction hose of a vacuum pumper truck. The nozzle comprises a tubular housing and the rotor within the housing near the intake end. The rotor includes a hollow cylindrical canister and spiral vanes on its exterior. Ambient air enters an air tube, penetrates the side of the housing and supplies ambient air to the interior of the canister. The air exits through outlet ports into the liquid waste as it moves past under vacuum. The injected air reduces the density of the liquid waste, speeding up the pumping process and reducing the incidence of blockages.

Abstract translation: 进气喷嘴安装在真空泵车的抽吸软管上。 该喷嘴包括一个管状壳体，该转子位于壳体内靠近进气端的位置。 转子在其外部包括一个中空的圆柱形罐和螺旋叶片。 环境空气进入空气管，穿过外壳的一侧，并向室内提供环境空气。 当空气通过真空时，空气通过出口进入废液。 喷射的空气降低了液体废物的密度，加速了泵送过程并减少了堵塞的发生。

Abstract: A macerator (32), e.g. for sewerage, including two stacks of interleaved contra-rotating cutters and spacers is mounted in a macerator chamber (30) having an inlet (60) and an outlet (62). The chamber (32) has a sump (80) upstream of the stacks of the cutters, which are mounted at such an angle that hard, solid material such as stones and metal fall under gravity through the influent into the sump.

Abstract: A tool holder clamp fits over the suction hose or intake nozzle of a vacuum pumper truck. The clamp takes the form of two or more C-shaped sections that can bolt together over the hose, with each C-shaped section having one or more through bores serving as sockets for holding a tool such as a flashlight or the head or nozzle of a jet hose. The sockets have associated slots to permit the socket to be snugged down against the tool.

Abstract: A method and apparatus for forming a cement or plaster slurry, for example, for use in mines, in which bags of cement or plaster are fed into a substantially closed chamber, are ruptured, and water is fed into the chamber at a controlled rate. The resulting mixture is fed into a macerator which serves to comminute the bag material and to mix the cement or plaster which is then fed into a pump, preferably a positive displacement pump, such as a helical gear pump and is thus pumped on to the point of use.
Abstract translation: 用于形成水泥或石膏浆料的方法和设备例如用于矿井中，其中将水泥或石膏袋进料到基本封闭的室中，并以受控的速率将水送入室中。 将所得混合物进料到浸膏机中，该碎片机用于粉碎袋材料并混合水泥或石膏，然后将其进料到泵中，优选为正排量泵，例如螺旋齿轮泵，并因此泵送到点 的使用。

Abstract: The invention is a screening device suitable for screening a liquid material having solid matter suspended in it, which comprises a number of sets of discs, the discs of each set being rigidly mounted on a shaft, with the discs on each shaft being separated from one another axially, means mounting the shafts about parallel axes, with the discs of adjacent shafts being interleaved with one another and means to cause the shafts to rotate independently in the same rotational sense such that successive shafts rotate progressively faster to cause the solid matter suspended in the liquid material to be moved in a direction from the slowest shaft to the fastest shaft. The device is used particularly in sewage processing plants.
