Title: Apparatus for Heating Fluids
Inventor: GRIGGS JAMES L
IPC: F24J3/00
Filed: 1994-02-10
Abstract: A system for the heating of fluids by causing severe turbulence of the fluid within a cavity of a housing (16). The device utilizes a rotor (12) closely received within a cavity, the rotor mounted upon a rotatable shaft (14), with the surface of the rotor (12) provided with a plurality of uniformly-spaced recesses (20) oriented at a selected angle to the surface. The shaft (14) is journalled in bearing assemblies (46,48) and seal units (50,52) at end walls (44) of the housing (16), and the shaft (14) is rotated by any suitable motive means (17). The heated fluid then is stored in any suitable storage facility, or utilized for any desired purpose. The system is specifically described for the purpose of heating water. This heated water is for standard use in a facility and, if desired, to provide heat input to air within that facility. Several embodiments of the conversion unit are given together with system elements to provide desired control of the heating of the water and of the facility. The preferred conversion unit has readily replaceable bearing assemblies.   <IMAGE>

Title: Fabrication of electronic devices with an internal window
Inventor: VAKHSHOORI DARYOOSH
IPC: H01S5/00
Filed: 1994-03-16
Abstract: - 10-FABRICATION OF ELECTRONIC DEVICES WITH AN INTERNAL WINDOW Abstract A process is described of producing devices, such as vertical cavity surface emitting lasers or resonant cavity light emitting devices, with an insulating region between an active region and top electrode, the insulating region having a centrally located window permitting passage of the electric current from the topelectrode to the bottom electrode centrally of the active region. The insulatingregion is formed by ion implantation. The window is defined by a photoresist mask formed by angle etching a photoresist masking layer by RIE, so as to form the mask with parallel side walls inclined at an angle to the normal to the masked surface. The ion implantation is conducted at the same angle and parallel to the side walls of of the mask. This permits fabrication of devices individually or in arrays. An exemplary independently addressable top emitting 8x18 YCSEL array (VCSELA) with GaAs multi-quantum well gain region was fabricated with excellent properties using the angle etched mask. The typical threshold current and voltage of the exemplary devices in this array are approximately 4 mA and 2.65V respectively. The L-I-V characteristics of the devices do not change by current annealing. Also, a comparison between devices produced by using the novel angled implantation mask and devices product by using conventional lithography implantation mask indicates the importance of the implantation mask preparation on the final VCSEL operatingcharacteristics.

Title: Disposable Needle Holder
Inventor: FAYNGOLD ZEV
IPC: A61M5/32
Filed: 1994-03-25
Abstract: A needle holder assembly having a sleeve that slidably receives a needle holder having a needle assembly attached thereto. After the need holder assembly has been used to collect a sample of body fluid, the needle holder is slid from its initial retracted position to a permanently locked extended position.

Title: A steerable drilling assembly for mounting on the end of a drill string to drill a borehole in an underground formation
Inventor: HALLUNDBAEK JORGEN
IPC: E21B4/02
Filed: 1992-11-18
Abstract: ABSTRACT OF THE DISCLOSURE            A steerable drilling assembly for mounting on the end of a drill string serves to drill a horizontal borehole in an underground formation.  The drilling assembly comprises a mud motor and a drill bit driven by said mud motor and having an axis of rotation which forms an angle with the axis of the drilling assembly, as well as a self-propelling drive assembly for substantially translatorily advancing the drilling assembly in the formation and exerting on the drill bit the pressure necessary for the drilling, said drive assembly being provided with driven wheels which are pressed against the wall of the borehole by the mud pressure and are pulled free from the wall when the pressure is relieved.  A swivel is inserted between the drive assembly and the mud motor, said swivel consisting of successively - seen in the flow direction of the mud -arranged first and second mutually rotatable swivel parts.  The swivel moreover incorporates a brake to impede the rotation of the two swivel parts with respect to each other.  Furthermore, the swivel incorporates a coupling arrangement which is so adapted as to be capable of locking the two swivel parts together  by  varying  the  volume  flow  of  the  mud  in a predetermined manner, determining whether the drilling assembly is to drill straight ahead or change direction.

Title: Refractory metal swarf composition and method of making same
Inventor: MEGY JOSEPH A
IPC: C22B34/10
Filed: 1992-10-05
Abstract: A clean refractory metal SWARF particle product is made from refractory metal SWARF. The SWARF particles are produced with coolant at a temperature of less than 650 °C to prevent formation of refractroy metal oxides and ni-trides. The SWARF particles are comminuted to reduce the particle size of the SWARF slivers and to liberate residual coolant. The comminuted SWARF slivers are washed with a displacement wash to remove the bulk of the coolant and subject to a counter-current wash to remove substantially all of the coolant components to produce clean SWARF parti-cles. The clean SWARF particles can be pressed into bri-quettes and sintered at elevated pressures or mixed with an alkali metal refractroy metal halide salt, pressed at elevated pressures into SWARF/salt briquettes and dried. The bri-quettes are non-pyrophoric.
