IPC: G11B5/187
Filed: 1991-06-13
Abstract: In an improved process for fabricating thin film head sliders from a wafer on one face of which a plurality of electromagnetic devices are arranged in rows, a single-row bar is mechanically processed to form sliders while it remains an integral part of the wafer, or after it is bonded to a fixture under a condition which induces no bow on the bar. Alternatively, a double-row bar sliced from the wafer is used for fabrication of sliders, wherein each single-row bar is mechanically processed while it remains an integral part of the double-row bar, or after it is bonded to a fixture as an integral part of a double-row bar followed by severance of the bonded double-row bar into two single-row bars. The process eliminates or materially reduces any inducement of bow of the bar, which is a serious cause of throat height control problem associated with the prior fabrication methods.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention provides a sorting method and a sorting device for sorting particles according to their settling velocities in a fluid medium. According to one aspect, the sorting method comprises admitting particles into a longitudinally vertically positioned container containing a fluid and allowing the particles to settle for a specified period of time under the influence of gravitational forces resulting in separation of the particles according to their settling velocities, followed by rotating the container by 90 degrees in order for the container to take a longitudinally horizontal position and thus allowing the separated particles to settle down and be collected in a sorted fashion. The sorting device comprises a container and means for achieving sorting of particles using this sorting method.

Abstract: A high frequency amplifier containing: a constant envelope signal generation circuit for transforming an input signal to form two constant envelope signals where phases of the constant envelope signals correspond to an amplitude of an envelope of the input signal; two amplifying circuits for separately amplifying two constant envelope signals; and a power synthesizing circuit for synthesizing the first and second amplified signals to generate an amplified signal of the input electric signal, and reflecting remaining components of the first and second amplified signals which remaining components remain in the above synthesizing operation, toward the first and second amplifying circuits. Further, an input impedance of the power synthesizing circuit may be controlled by shifting phases of the above reflected components by respectively predetermined amounts, or by adaptively shifting phases of the above reflected components responding to an input level, so that a total efficiency of the high frequency amplifier is maximized. The high frequency amplifier may contain, instead of the above two amplifying circuits and the power synthesizing circuit, a circuit for inverting a phase of one of the two constant envelope signals; and a single-ended push-pull amplifier circuit for receiving the other of the two constant envelope signals, and an output of the phase inversion circuit, and synthesizing the received signals to generate an amplified signal of the input electric signal.

Abstract: There is described an improved solid waste handling system for screening and grinding solids entrained in an influent liquid  stream  that  utilizes  at  least  one  solids  diverter horizontal rotating screen unit fixedly mounted in the liquid stream such that the flow moves through it and that is partially immersed  in  the  influent  liquid  stream.    The  screen  unit comprises a rigid frame assembly and a screen member mounted for rotation on the rigid frame assembly such that the screen member moves horizontally relative to the liquid stream.  The screen is rotated to cause solids of the influent stream larger than openings in the screen to impact upon an upstream face of the screen to be moved horizontally in the direction of screen movement to one side of the liquid stream.  A solid waste grinder is fixedly mounted adjacent to the screen unit whereby solids diverted from the influent stream are conveyed from the screen to the solid waste grinder and finely ground prior to discharge through an outlet of the solid waste grinder.

Abstract: A hay feed wall (46) extends longitudinally of the mixer chamber with its lower edge closely adjacent to a chopper auger (32). A control wall (48) extends laterally from a chamber side wall over the chopper auger (32) to the feed wall (46) to cause hay bales to be channeled into the chopper auger (32) whereupon the hay is chopped by the knives (40) on the outer peripheral edge of the auger flighting. The hay is then augered out of the chopping chamber into the mixing chamber where it is acted upon by a lower mixing auger and a rotor (24) in the main chamber (26). The lower corner (80) of the feed wall (46) engages the lower portion (66) of the control wall (48) to pivot the control wall (48) to a substantially vertical position as the feed wall (46) is pivoted to that position by operation of a cable (84) connected to a winch (82). <IMAGE>

Title: Heat exchanger for dehumidification of compressed air and the compressed air dryer in which it is installed
Inventor: LAUMEN MICHAEL
IPC: B01D53/26
Filed: 1992-04-06
Abstract: ABSTRACT                        Summary Heat exchanger for the dehumidification of compressed air and the compressed air dryer in which it is installed.             Heat exchangers in which at least either on the heating side or the heated side the heat exchanger surface takes the form of the inner surface of a sintered material are characterized by extremely high heat transfer performance.  The disadvantage, however, is the relatively high flow resistance of the sintered material.             The invention involves a heat exchanger which is particularly suitable for the dehumidification of compressed air and achieves a lower pressure loss than in sacrifices in heat transfer performance.  The heat exchanger has sintered matrix with a particle size of more than 1.5 mm and preferably in the range between 1.6 and 2.0 mm.  With this particle size the pressure loss remains within an acceptable range, while at the same time the heat exchange performance is reduced only negligibly compared with particle sizes of less than 1.5 mm.

Title: Flow actuated safety valve
Inventor: DOLLISON WILLIAM W
IPC: E21B34/08
Filed: 1992-05-07
Abstract: FLOW ACTUATED SAFETY VALVE                           ABSTRACT         A retrievable subsurface safety valve positioned in a well conduit is actuated to close by a predetermined flow rate through the safety valve.  A valve member (16) having a sealing surface (16b) is movable by flow to sealingly engage an annular seat (12) in the valve, closing the valve to flow.  All the forms of safety valve described have retrievable variable weight assemblies (23) which releasably lock in the valve member for varying the flow rate at which each valve closes.  In two forms of the invention, the weight assemblies (25 or 38) when retrieved from the valve members leave the valve members open for passage of well tools through the valve members.  In one form, the valve housing (42) has variable biasing means (54,55) for biasing the valve member (53) toward open position and this safety valve may be operated to expend the seat, housing and valve member with or without the variable weight assembly.

Abstract: A tampon applicator assembly is disclosed wherein the protective wrap which initially packages the tampon applicator provides a simplified covering for disposal of the spent applicator.   The tampon applicator wrap is opened at a pre-determined location such that a discrete portion remains which is significantly longer than the applicator barrel member.  Accordingly, after tampon ejection, with the plunger telescopingly located within the barrel, that unit is then inserted within the discrete wrap portion, which includes a substantial length extending beyond the reinserted applicator.          That substantial length is then twisted and tucked into the opened end  of  the  applicator  to  maintain  closure  of  the  wrap  for applicator disposal.
