摘要： Loosely poured granular material is compacted by a burst of air under pressure which is built up in a space Q1 and is abruptly released through the outlet end of a passageway Q3 which opens toward the material surface. While the pressure in Q1 is being built up and until released, it is restrained by a sealing member which concurrently covers the outlet side of Q1, the input end of passage Q3 and an accelerating space Q2. The sealing member is held in place by a counterpressure in a space Q4 acting on a larger surface area than Q1. The pressure is suddenly decreased in Q4, abruptly unbalancing the pressures and releasing the pressurized gas from Q1 into Q3 and against the surface.

摘要： In order to make castings from casting sand or another moldable mixture, a pressure surge wave is used which has upper and lower limit values which values have been established by an optimal selection of a pattern of pressures. The other moldable mixture comprises particles of raw material, binder, water, and, if need be, additives. The rise in pressure takes place with an increasing pressure gradient, dp/dt, of at least 50 atmospheres (absolute)/second. A minimum pressure of at least 2 atmospheres (absolute) is maintained for at least 0.01 second. The pressure drop takes place at a decreasing pressure gradient, -dp/dt, of up to about 2.0 atmospheres (absolute)/second. The disclosed values represent an optimalization, in view of a simple design and economy of operation, with a surprisingly good compacting.

摘要： There is disclosed a process for applying a refractory filler and a hydrate of Al(H.sub.2 PO.sub.4).sub.3 or polyphosphates as a binder to a single or multi-layered carrier material to form a single or multi-layered, thin-walled structure subsequently hardened on the carrier material. The hardening is preferably conducted at a temperature below 400.degree. C. There is thus obtained a phosphate-bonded, thin-walled shaped article which is refractory at temperatures above 1300.degree. C.

摘要： The invention relates to a wheel for centrifugal jet machines with two rotating wheel discs, a plurality of centrifugal blades distributed evenly around the periphery, each blade being provided with lateral ribs or strips, the blades being insertable from the inside into radial grooves in the wheel discs and held therein by fixed stops. According to the invention, the length of the lateral strips is shorter than the diameter of the central free space of the wheel formed by the inside ends of the blades. Moreover, the width of the part of each centrifugal blade projecting beyond the lateral strips is smaller than the distance between the two discs. As a result of this dimensional relationship, the centrifugal blade can be inserted from the outside between the wheel discs in a position twisted in relation to the centrifugal axis until the lateral strips are in the central, free space and then are moved radially outwardly to a fixed stop from the inside in the grooves of the wheel discs, as a result of which centrifugal blades of any arbitrary length may be used.
摘要翻译：本发明涉及一种用于具有两个旋转轮盘的离心式喷射机的轮子，围绕周边均匀分布的多个离心叶片，每个叶片设置有横向肋条或条带，所述叶片可从内部插入轮中的径向凹槽光盘并固定在其中。根据本发明，横向条的长度短于由叶片的内端形成的轮的中心自由空间的直径。此外，突出超过侧向条的每个离心叶片的部分的宽度小于两个盘之间的距离。作为这种尺寸关系的结果，离心式叶片可以从轮盘之间的外部插入到相对于离心轴线扭转的位置，直到侧向条带处于中心的自由空间中，然后径向向外移动到从车轮盘的槽中的内侧固定停止，由此可以使用任意长度的离心叶片。

摘要： Rotary mixing apparatus particularly suitable for treatment of foundry sand having a drum mounted for rotation about an axis which is horizontal, or at least approximately horizontal, operates to treat bulk material such as foundry sand which is placed within the rotating drum. Stationary deflection apparatus is arranged within the drum in the upper range thereof and a rotating impact rotor is mounted within the drum so that as the drum rotates and the material contained therein is propelled into the upper region of the drum it is deflected by the deflection apparatus and formed into a downwardly falling jet which is directed at the rotating impact rotor.

摘要： Apparatus for removing from a workpiece moving in a given feed direction a mixture of blasting media and cleaning residue located upon the workpiece particularly adaptable for use with workpieces having relatively large horizontal surfaces. A damming device is located relative to the moving workpiece to dam the mixture on the workpiece and cause it to accumulate in front of the damming device. A mechanical cross conveyer engages the dammed-up mixture adjacent the damming device and a blowoff device for blowing the mixture from the workpiece is also provided. A baffle plate is arranged to extend in a direction obliquely to the feed direction of the workpiece between the damming device and the blowoff device. The baffle plate is arranged to conduct the mixture blown off the workpiece by the blowoff device over the damming device and on to the cross conveyor.

摘要： An auxiliary device for use with a permanent mold in casting operations includes a cover plate having an upwardly and a downwardly facing surface. In place on the permanent mold, the downwardly facing surface defines the upper limit of the mold cavity. At least one pipe extends through an opening in the cover plate with its lower end in the plane of the downwardly facing surface of the cover plate. An annular recess located in one of the downwardly facing surface of the cover plate or the lower end of the pipe, encircles the lower end of the pipe radially outwardly from its opening. A breaking core can be incorporated as a part of the lower end of the pipe or it can be formed as a separate member. The pipe can be used only to feed additional molten metal into the mold as the poured metal starts to solidify or it can be used both to pour the molten metal into the mold cavity and then to provide the additional feed as the metal solidifies.

摘要： A coupling for smooth pipe includes a housing, a sleeve nut threaded onto the housing, a gasket inside the housing and a thrust and locking ring structure within and between the housing and sleeve nut. The housing has a tapered inner surface to compress the gasket. When the nut is threaded onto the housing, the ring structure is axially moved by a shoulder on the nut to compress the gasket. The nut then radially deforms tongues on the locking ring structure to grip the pipe.

摘要： A coating liquid is squirted through a needle control nozzle directed into open end of internal threads of a fitting or tube and is deflected radially to form a spray cone by an air jet from a revolving nozzle set slightly in front and off the axis of the nozzle for the coating liquid. An end plate affixed to the revolving nozzle limits the forward spread of the spray cone, so that the coating thickness taper is cut off at the inner end of the coating on the threads. The thickness taper produced at the outer end of the threads by the spray cone favors easy engagement of the threads in making a tight threaded joint.
