摘要： A volumetric type rotary machine has a pair of rotors each of which has a plurality of teeth comprising tooth crests and valleys alternately disposed at equal angular intervals around the rotor in profile in a cross-sectional plane thereof perpendicular to the rotational axis thereof, which rotors are adapted to rotate in mutually opposite directions in mutually intermeshed state. In each rotor as viewed in the profile in the cross-sectional plane, the tooth crests and valleys respectively have convex and concave arcuate parts over specific peripheral extents thereof centered on the vertices and nadirs thereof, respectively, and remainder parts of involute curve shape between the extremities of the arcuate parts.

摘要： A screw blower comprising a pair of rotary driving shafts disposed in parallel relation and a pair of rotors rotatable with the driving shafts. The rotors are provided with meshing teeth each having a helix angle. A casing surrounds the rotors and forms therewith an intake chamber and an exhaust chamber. Grooves, which are formed between the meshing teeth, come into communication with an opening of the exhaust chamber as the rotors undergo rotation. The opening of the exhaust chamber extends over the full length of the rotors. Each of the rotors has a predetermined number of teeth and a sufficiently large helix angle such that gases trapped within the grooves are immediately discharged to the exhaust chamber without being compressed as the rotors rotate. The opposedly disposed meshing teeth are meshed in a male and female relationship.
摘要翻译：一种螺旋鼓风机，包括一对平行设置的旋转驱动轴和一对可与驱动轴一起旋转的转子。转子设有各自具有螺旋角的啮合齿。壳体围绕转子并与其形成进气室和排气室。形成在啮合齿之间的凹槽随转子进行旋转而与排气室的开口连通。排气室的开口在转子的整个长度上延伸。每个转子具有预定数量的齿和足够大的螺旋角，使得被捕获在槽内的气体立即被排出到排气室，而不会随着转子旋转而被压缩。相对设置的啮合齿以男性和女性关系啮合。

摘要： A dual screw-type pump is provided with a means for balancing the resultant dynamic axial thrust on the screw assemblies during operation of the pump. The resultant thrust on each assembly is absorbed in part by a circular piston on the assembly near the rear of the pump and the remainder by a thrust bearing engaged with the assembly near the front of the pump. The longitudinal position of one of the screw assemblies is selectively adjustable relative to the position of the other screw assembly to balance the thrust on the screw assemblies.

摘要： The invention concerns a prefabricated building structure, one which employs a series of structural elements of novel design that permits even an inexperienced person to quickly and easily assemble a building. These structural elements all are designed to hold taut at least one flexible sheet spanning the space defined by the elements, this sheet being received, with a resilient spline, in a keyhole-shaped slot provided in each structural member, this slot being of a unique design. A minimum of different structural elements are employed in the building, these different structural elements all being described in the following specification.
