Title: Process for manufacturing galvannealed steel sheets having excellent anti-powdering property
Inventor: SAGIYAMA MASARU
IPC: C23C2/28
Filed: 1991-12-27
Abstract: It is an object to provide a process for manufacturing galvannealed  steel  sheets  exhibiting excellent anti-powdering property when press formed, and uniform frictional properties in a coil.                 A steel  strip  is  galvanized in a bath having a low aluminum content after entering it at a high temperature as defined in relation to the aluminum content of the both, so that the formation of a ~ phase may be promoted.  Then, the strip is heated for alloying in a high-frequency   induction  heating  furnace  so  as  to  have  a temperature not exceeding 495°C when leaving the furnace to yield a plated  steel  strip having  a  coating  containing  a uniformly distributed ~ phase.  After such heat treatment and cooling, the strip can be plated with an iron or iron-alloy top coating having an iron content of at least  50% and a coating weight of at least 1 g/m2 to achieve an improved press formability.

Inventor: OLSON DARWIN C
IPC: F16L37/12
Filed: 1992-12-18
Abstract: A quick connect coupling for connecting a tube to a body having a stepped bore formed therethrough. The coupling includes a sleeve which is press fit in the bore.      The inner surface of the sleeve has a cylindrical portion, a radially outwardly extending frusto-conical portion, and an internal shoulder defined therebetween. A collet is disposed within the sleeve having a boss portion which is slightly smaller than the inner diameter of the cylindrical portion sleeve. The boss portion supports and guides the collet for co-axial movement relative to the sleeve. The collet further includes an enlarged end portion having an external shoulder and a extending frusto-conical surface.      The frusto-conical collet surface is disposed within the frusto-conical sleeve surface. The tube is inserted within the coupling within the collet. When it is attempted to move the tube out of the body, the frusto-conical collet surface engages the frusto-conical sleeve surface of the sleeve. Also, the external collet shoulder engages the internal sleeve shoulder. As a result, the collet (and the tube engaged thereby) are positively retained within the coupling and the body.

A plurality of clearance slots are provided angularly spaced around the circumference of the generally circular load transferring surface.  A generally rectangular load transferring pocket is located in the socket adjacent a bottom surface thereof and has clearance reliefs defined thereon.  A relief cavity is located in the socket between the generally circular load transferring surface and the generally rectangular load transferring pocket.  The relief cavity in conjunction with the clearance slots and the clearance reliefs enable the tooth to be mounted on the adapter that has four raised helical threads disposed thereon without having to rotate the tooth during assembly or disassembly thereof.

Title: Telephonic Headset Structure for Reducing Ambient Noise
Inventor: BARTLETT CHARLES S
IPC: G10K11/178
Filed: 1993-07-06
Abstract: Telephone headsets used by operators and airline pilot headsets are subject to substantial amounts of interfering ambient noise which detract from the intelligibility of incoming speech.  Noise reduction circuitry does not altogether eliminate the interfering sound.  A headset speaker and error microphone housing are disclosed which enable a greater amount of unwanted noise elimination.  The speaker and microphone are configured closely with respect to each other and also to the user's ear.  They are acoustically isolated in their own chamber.  The microphone is located approximately on the speaker axis and protrudes substantially into the user's ear; and also is disposed close to the speaker cone surface.  Additional acoustical tuning features include venting ports in the housing, and acoustic damping padding at the microphone entrance and on either side of the speaker.  These expedients enhance the ability of the noise-cancelling circuitry to effectively reduce the undesired noise heard by the user.

Abstract: Abstract Of The Disclosure Apparatus for producing a continuous web of adhesive labels is placed in nearby proximity to a computer printer having a sheet-feeding tractor mechanism.  A spool of base tape material comprises superposed,  continuous webs of a print-receiving  layer and a carrier layer with the wider carrier layer including longitudinally spaced  perforations  extending  in  two  laterally  spaced  rows outwardly of each side of the label layer.  Spools of base tape and transparent overlay tape materials are rotatably mounted upon spindles on the apparatus with the base tape web being directed from its spool to and through the sheet-feeding mechanism of the printer.  The perforations in the carrier layer are registered with the pins of the sheet-feeding mechanism and the printer performs a printing operation upon the label layer of the base tape web.  The printed base tape web is directed back to the apparatus where the perforations in the carrier label are again placed in registry with pins of a web guide on the apparatus.  The web of base tape is guided from the printer and the web of overlay tape is guided from its spool to the entry of a pair of tangent pressure rollers, one of which has a handle for manual advance of the superposed webs. As  the  webs  pass  through the  rollers,  the  overlay  tape  is superposed with an adhered to the printed label layer.
