摘要： An air directing baffle for a random orbit sander. The baffle includes a main body portion forming an annular opening, a pair of neck portions extending approximately circumferentially opposite from one another, and a pair of recessed portions formed in each of the neck portions. The neck portions extend into airflow registration with a plurality of exhaust slots formed in a shroud rotatably disposed at a lower portion of a housing of the sander. The annular opening is adapted to fit over a boss portion protruding from a lower face surface of the housing of the sander to thus permit the baffle to be rotated freely relative to the housing. The recessed portions in each of the neck portions of the baffle inwardly engage with a pair of inwardly protruding shoulder portions formed in an interior area of the shroud. The interengagement of the baffle with the shroud permits the neck portions of the baffle to be maintained in alignment with the exhaust slots in the shroud as the shroud is rotated by a user during operation of the sander. Thus, the baffle is free to rotate relative to the housing but not relative to the shroud itself. The baffle serves to more effectively direct a cooling airflow drawn in by a fan through inlet slots in a top member associated with the housing such that the airflow is more directly exhausted from the interior area of the shroud. The design of the baffle further does not complicate the assembly of the sander 10 or otherwise add significantly to the overall cost of the sander.
摘要翻译： 用于随机轨道砂光机的导风挡板。 挡板包括形成环形开口的主体部分，大致周向相对延伸的一对颈部部分和形成在每个颈部部分中的一对凹部。 颈部延伸成与形成在可旋转地设置在砂光机的壳体的下部的护罩中的多个排气槽的气流对准。 环形开口适于装配在从砂光机的壳体的下表面突出的凸台部分上，从而允许挡板相对于壳体自由旋转。 挡板的每个颈部中的凹部向内接合形成在护罩的内部区域中的一对向内突出的肩部。 挡板与护罩的相互接合允许挡板的颈部保持与护罩中的排气槽对准，因为在砂光机操作期间护罩由使用者旋转。 因此，挡板相对于壳体自由旋转，但不相对于护罩本身旋转。 挡板用于更有效地引导由风扇吸入的冷却气流通过与壳体相关联的顶部构件中的入口狭槽，使得气流从罩的内部区域更直接地排出。 挡板的设计进一步不使砂磨机10的组装复杂化，或者明显地增加了砂磨机的整体成本。

摘要： A random orbit sander having a braking member for frictionally controlling the speed of a platen of the sander when the sander is removed from a workpiece during operation. The braking member includes a base portion, an outwardly flaring, relatively thin wall portion and an enlarged outermost edge portion adapted to frictionally engage an upper surface of the platen. The braking member is secured to the bottom of the shroud of the housing via a groove formed in its base portion. The braking member exerts a relatively constant spring force against the upper surface of the platen which limits the rotational speed of the platen to approximately 1200 rpm when the platen is lifted off of a work surface, without significantly degrading the performance of the sander under load. This prevents swirl marks and other undesirable scratches from being made in a workpiece when the platen is reapplied to the workpiece as a result of the platen having increased in speed to an unloaded, free-wheeling speed, and yet allows the platen to operate at or above the minimum desired working speed of about 800 rpm. The braking member is formed from polyester butylene terephthalate which is doped with approximately 2% silicon and approximately 15% teflon in the preferred embodiments. This material formulation, plus its geometry, allows the braking member to exert and maintain a relatively constant spring force of about 3.5 lbs. against the platen and to resist frictional wear once past an initial break-in period. The braking member also acts as a seal between the lower surface of the shroud and the upper surface of the platen.

摘要： A positive stirring consistometer cup includes a pair of wall blade members having radially inwardly extending blades which cooperate with radially outwardly extending blades of a paddle to uniformly apply shear throughout a substance to be tested. A split sleeve assembly eliminates an outer dead space, and an enlarged spacer member mounted on the shaft of the paddle eliminates an inner dead space, thereby enhancing the uniformity of the shear throughout the substance. A centralizing assembly centers the stationary paddle while causing a minimum of friction and wear to occur on the shaft of the paddle. In a method of using the positive stirring consistometer cup, the blades of the wall blade members and of the paddle stop in substantially aligned, coplanar relationship to facilitate cleaning of the elements after a test is concluded.

摘要： Methods and apparatus for cementing a pipe in a well bore penetrating one or more subterranean gas-containing formations without incurring substantial gas inflow are provided. The methods basically comprise the steps of placing a hydraulic cement slurry in the annulus between the pipe and the well bore, and moving the pipe during the transition period of the slurry. The moving of the pipe maintains the hydrostatic pressure exerted by the slurry on the gas-containing formations and prevents gas flow into the slurry and the well bore. The movement of the pipe is stopped when the slurry develops sufficient gel strength to substantially block gas flow through the well bore.

摘要： A hand-operated electric tool, especially a jigsaw, has a motor unit provided in the tool housing. The motor unit contains in a motor housing the stator and the rotor. One end of the rotor shaft projects from the motor housing and is mounted in two bearings fixed in the motor housing. A countershaft forms an extension of the rotor shaft and carries a toothed arrangement. The countershaft is coupled to the rotor shaft and is rotatably mounted in a bearing. The rotor shaft and countershaft engage axially with radial play and are coupled non-rotatably by co-operating radial projections and recesses receiving the projections. In the region of the overlapping portions of rotor shaft and countershaft, one of the shafts has an annular portion extending at least over a part of the circumference. The annular portion is substantially in line contact with an adjacent circumferential surface of the other shaft. The line contact permits misalignment of the rotor shaft and countershaft but reduces noise.

摘要： The present invention provides a method of preventing gas migration during primary well cementing. The method basically comprises the steps of displacing a cement slurry into the annulus between a string of pipe to be cemented in a well bore and the walls of the well bore, determining the initial surface pressure in the pipe after the cement slurry is placed in the annulus, displacing additional cement slurry into the annulus as is necessary to make up for losses in the surface pressure due to cement slurry gel strength development and volume reduction whereby the surface pressure is maintained substantially equal to the initial surface pressure until the cement slurry develops a predetermined gel strength sufficient by itself to prevent gas migration, and then allowing the cement slurry to set into a hard impermeable mass in the annulus.

摘要： A process for cementing adjacent a subterranean gas-containing zone, in which process a cement slurry containing a stabilized, dispersed gas is placed adjacent the zone. Sufficient gas is present in the cement slurry or is capable of being generated within the slurry to prevent the connate formation gas under pressure from passing into or around the cement prior to the time the cement has set up.

摘要： Methods and apparatus for the nondestructive testing of cement slurry samples as a function of time are disclosed. A sample placed in a temperature and pressure controlled autoclave is coupled to transducer means under computer control. Ultrasonic energy is propagated through the sample and the transit time is measured. A predetermined relationship relating transit time to compressive strength is employed and enables the determination of compressive strength. The measurements are repetitively performed on up to eight samples simultaneously and the time history of the development of compressive strength is recorded.
