摘要： A brake assembly permits axial rotation of a shaft in a first direction and retarding axial rotation of the shaft in an opposite, reverse direction. The brake assembly includes a rotary member for mounting to and rotation with the shaft; a fluid actuated brake mechanism for retarding the rotation of the rotary member and consequently the shaft upon pressure build up in the brake mechanism; a bi-direction pump for conveying fluid from a reservoir, the pump being driven by rotation of the shaft; and a control manifold for directing circulating the fluid from the pump through the brake mechanism and back to the reservoir without pressure build up, the circulation of the fluid preventing the accumulation of gas in the brake mechanism, when the shaft turns in the first direction and or directing fluid to the brake mechanism for activating the brake mechanism by fluid pressure build up to retard rotation of the shaft when the shaft turns in the reverse direction.

摘要： A gravity operated emergency system for a multi-story building is disclosed including an elongate track having a central rack which is disposed along an outside wall of the building. A traveller is provided which moves along the track and has a pinion which rotatably engages the rack. A pair of bearing members engage opposite sides of the track and these bearing members are pivotally attached to the traveller so that as the pinion is brought into contact with the rack the bearing members clear the respective sides of the track and when the pinion is fully engaged in the rack the bearing members are resiliently urged into contact with an inside face of the track. A velocity control mechanism is provided to control the rotational speed of the pinion in the rack, and hence the speed of the traveller relative to the track. During an emergency, the user is received in a harness which is connected to the traveller and the traveller slowly lowers the user to safety along the track.

摘要： A hydraulic drive system for actuating a reciprocating member such as a polished rod in a pump jack device, and for acting as a counterbalance and/or for energy conservation. The system has two hydraulic circuits and a prime mover. A first circuit includes a cylinder for driving an output member which may be connected to the polished rod, a first pump of the variable displacement, reversible flow type, together with a pair of fluid lines forming with the cylinder a closed-loop circuit. A controller is programmed to control the setting of the first pump so as to establish the velocity profile of the output member. A second hydraulic circuit is also in the form of a closed-loop containing first and second pumps, at least one of which is of the variable displacement type and is also controlled by the controller. The second and third pumps at least are of the pump/motor types, and the third pump has an input/output shaft connected to a flywheel so that as the third pump is driven as motor, it increases the speed of the flywheel. However, when the second circuit is controlled so that the second pump functions as a motor and the third pump functions as a pump, energy is extracted from the flywheel so that its RPM decreases. The first pump is driven by the prime mover, and the second pump, which can drive the first pump when it is functioning as a motor, may alternatively be driven by the prime mover as well or by both the prime mover and the first pump, if the latter functions as a motor, such as during the down stroke of the polished rod.
摘要翻译：一种液压驱动系统，用于致动往复运动的构件，例如在泵顶装置中的抛光杆，并用作平衡和/或用于节能。该系统有两个液压回路和一个原动机。第一电路包括用于驱动可连接到抛光棒的输出构件的气缸，可变排量，可逆流型的第一泵，以及与气缸形成闭环回路的一对流体管线。控制器被编程以控制第一泵的设置，以便建立输出构件的速度分布。第二液压回路也是包含第一和第二泵的闭环的形式，其中至少一个是可变排量型并且也由控制器控制。第二和第三泵至少是泵/马达类型，并且第三泵具有连接到飞轮的输入/输出轴，使得当第三泵作为马达驱动时，其增加飞轮的速度。然而，当第二电路被控制使得第二泵用作电动机并且第三泵用作泵时，能量从飞轮中提取，使得其RPM降低。第一泵由原动机驱动，第二泵可以在作为电动机起动时驱动第一泵，也可以由原动机以及原动机和第一泵两者驱动，如果后者用作电动机，例如在抛光棒的下冲行程期间。

摘要： An adapter for mounting dual wheels on small trucks normally equipped with single wheels, including a spacer assembly connected by elongated studs which thread onto the conventional wheel studs projecting axially from the hub flange. The elongated studs secure the spacer assembly to the flange and have outer ends projecting axially outwardly from the spacer assembly and receive wheel nuts which secure dual rims to the outer end of the spacer assembly. The adapter is easily mounted and ensures a coaxial relationship with the hub flange. The rims may be changed without removing or disturbing the spacer assembly.

摘要： A pump jack, such as the type capable of use in pumping crude oil from an oil well, the pump jack including a double acting piston and cylinder motor with the piston rod of the motor being adapted to be connected to the polished rod projecting upwardly from a well head. A variable displacement hydraulic pump, which is driven by a motor or engine, is included in a closed hydraulic loop wherein conduits are connected to a pair of output ports of the pump. A pump control means controls the direction and volume of flow in the loop so as to establish the stroke of the piston rod. A compressible fluid counterbalance is provided for accumulation of energy during a down stroke of the piston rod so that the energy may be returned to the piston during the up stroke. An economical and versatile unit may be produced by mounting a counterbalance cylinder coaxially above the motor and providing the counterbalance with an additional closed chamber in fluid communication with a charged chamber of the counterbalance. The additional chamber may be provided in hollow structural members forming a support portion of a pump jack tower. The tower can be mounted on a portable base or deck by way of a pivot connection so that the tower can be swung down to a horizontal transportation position.

摘要： A progressive cavity pump of the type having a stator member and a rotor member disposed within a cavity in the stator member and being rotated while being permitted to orbit about a central axis of the stator in operation, one of the members being formed of resilient material and the other of rigid material. The rotor is of helical formation having a constant circular transverse cross-section and defining a single-start thread of a preselected pitch and direction, and the cavity of the stator is in the form of a two start thread of the same direction as the rotor and twice the pitch, the cavity in transverse cross-section has an outline defined by a pair of spaced semi-circular concave ends and a pair of sides joining the semi-circular ends. The semi-circular ends have a diameter slightly less than the diameter of the cross-section of the rotor for establishing an interference fit between the rigid and resilient members. The pair of sides have an inward curvature so that the distance between the pair of sides is slightly less than the diameter of the circular ends whereby sealing areas of increased interference are provided between the members. Unlike known progressive cavity pumps, a high pressure output is possible without making the pump inefficient or of a prohibitive length.

摘要： A device for magnetically treating seeds prior to planting so as to increase the yield of plants grown from the seeds. The device includes a tubular member provided with an internal support for securing a permanent magnet therein so that as seeds are poured through the tubular member, they are magnetically treated. The magnet, which has opposite poles disposed at opposite ends thereof, is oriented with its longitudinal axis extending in the direction of the passage, the passage adjacent the magnet being of substantially annular shape in cross-section whereby a uniform cylindrical shaped magnetic field occupies the annular passage through which the grain must pass. The tubular member has a converging portion in the direction of seed travel so as to provide an area of maximum constriction adjacent the magnet which results in the seeds being funnelled radially inward towards the more concentrated magnetic field closest to the magnet. The converging or constricted portion may be shaped to provide the flow of seeds along streamlines so that the rate of flow is enhanced.
