Title: Fire resistant helicopter deck
Inventor: SUTTER R FRANK
IPC: A62C3/02
Filed: 1987-10-02
Granted: 1992-04-14
Abstract: FIRE RESISTANT HELICOPTER DECK ABSTRACT OF THE DISCLOSURE     The present helicopter deck makes use of a passive fire-fighting system.  Extruded aluminum beams (20) on a base (12, 14) support an upper platform  (50)  for supporting the helicopter. The support beams (20) provide a space between the base and the upper platform (50).  The upper platform (50) is a grating, which permits fuel to pass through it.  The support beams (20) support batts  (54)  of  thin,  spaced  strips  of  high-heat  conductive material below the upper platform (50).  The support beams (20) also support deck plates  (58) below and spaced from the batts (54).   The material of the batts (54)  conducts localized heat from one location of the batts (54) to a more even, lower temper-ature spread generally through the batts (54).  The deck plates (58) catch fuel that passes through the batts (54) and slopes to cause the fuel to flow away from the deck.

Abstract: DYE SETTING STEAM CHAMBER APPARATUS AND METHOD               Abstract of the Disclosure A dye setting apparatus for use with carpets, mats and the like comprises a cover having a generally planar interior surface pivotally connected to a support surface.          The cover includes a steam containment and support structure having an interior channel flow connected to a steam source.          The cover, support structure and support surface form a confinement chamber for the carpet.  Steam is released into the chamber from apertures in the support structure to set dye in the carpet.  The interior surface of the cover is constructed of a material which is generally non-heat conductive and somewhat water absorbent, such as plywood, to preverit steam from condensing as droplets on the interior of the cover and dropping on the carpet during dye setting.

Title: Rotation rate nulling servo and method for a fiber optic rotation sensor
Inventor: STEELE JAMES R
IPC: G01C19/72
Filed: 1988-03-14
Granted: 1992-04-07
Abstract: ROTATION RATE NULLING SERVO AND METHOD     FOR FIBER OPTIC ROTATION SENSOR     ABSTRACT OF THE DISCLOSURE Setting the driving signal of a phase modulator in the sensing loop of a fiber optic gyroscope to zero for a period of time ? equal to the transit time of the light waves through the gyro causes the gyro to assume a known zero reference state. In this zero reference state the counterpropagating light waves are in phase except for the phase shift caused by rotation of the sensing loop. During this zero reference state, a bias signal for demodulation purposes and a signal that will cause a phase shift equal and opposite to the rotation-induced phase shift are applied to the phase modulator. These signals null the rotation-induced phase shift as seen by a photodetector for a period equal to the transittime.

Title: Electrode wire for a roller seam welding machine
Inventor: URECH WERNER
IPC: B23K35/02
Filed: 1988-05-24
Granted: 1992-04-14
Abstract: ABSTRACT OF THE DISCLOSURE:            An electrode wire which, in contrast to conven-tional electrode wire, is provided with flanges formed on it to support it on the circumference of a roller electrode at both sides of a guide groove.  The electrode wire is broader than its contact area on the work being welded and has a considerably broader contact area on the work being welded than the conventional electrode wire.  As a result, metal sheets, for example lead-coated metal sheets of fuel tanks, are pressed together alongside the weld nugget as a result of which gaping apart of the sheets alongside the weld nugget and lateral tearing of the weld nugget are prevented.  The profile of the electrode wire projecting beyond the guide groove is very thin and cannot be deformed laterally under transverse forces even if the electrode wire becomes soft during the welding.  Welds produced with the electrode wire have a considerably better fatigue strength than welds produced with the conventional electrode wire.

Title: Method and apparatus for use in constructing an orthodontic appliance
Inventor: WILSON WILLIAM L
IPC: A61C7/00
Filed: 1988-10-28
Granted: 1992-11-24
Abstract: Abstract Method  and  apparatus  are  provided  for  fabricating  a precisely dimensioned orthodontic appliance.  The apparatus includes a lingual tube/molar band assembly having a molar band attached to a patient's teeth and one or more lingual tubes.  The apparatus also includes a transfer insert for use as a marking device and transfer lingual tubes, corresponding to the lingual tubes of the lingual tube/molar band assembly. In practicing the method, the transfer insert is seated in the lingual tubes of the lingual tube/molar band assembly.  A negative impression is then taken with the transfer insert being absorbed into the impression material.  The location of the lingual tubes are marked in the negative impression using the transfer insert.   The transfer lingual tubes are then joined to the transfer insert.  Stone is then poured into the negative  impression  to  create  the  positive model  of  the patient's teeth.  Upon separation of the negative impression from the stone cast, the transfer lingual tubes adhere to the positive model while the transfer insert remains with the negative  impression.   Since the location of the transfer lingual tubes  in  the  stone  model  precisely  matches  the position of the  lingual tubes  in the patient's mouth,  a precisely  dimensioned  orthodontic  appliance  can  then  be fabricated using the positive model and the transfer lingual tubes.

Title: Liquid level regulator device
Inventor: DUNCAN MALCOLM
IPC: H01H35/18
Filed: 1989-02-27
Granted: 1992-12-01
Abstract: Abstract of the Disclosure A liquid regulator device has a buoyant body which is anchored to a side of the vessel by an electrical conductor.  The body contains a movable ballast in the form of a ball and an attitude sensitive switch connected to the electrical conductor.  The buoyant body floats in the liquid with one end in the uppermost position.  Changing the liquid level tensions the electrical conductor causing the body to tumble.  When the body has tumbled through a predetermined angle, the ballast moves from one end of the body to the other to cause the body to rapidly assume the reverse orientation.  This causes the attitude sensitive switch to change state, which is used to control the liquid level.
