Title: Thermal anti-icing of aircraft structures
Inventor: ARNOLD MICHAEL J
IPC: F02C7/047
Filed: 1992-09-17
Abstract: An aircraft structural component comprises a forward compartment (17) formed by a forward bulkhead (19) and a skin structure (21) which extends forwardly of the forward bulkhead (17) and which has an outer surface which requires to be protected from accumulation of ice thereon, and a rear compartment (18) formed between the forward bulkhead (19) and a rear bulkhead (20). A supply duct (25) extends through the rear compartment (18) and into the forward compartment (17) for the delivery thereto of pressurised hot gases for distribution over the inner surface of the skin structure (21) to prevent accumulation of ice on the outer surface of the skin structure (21). A protective shroud duct (31) surrounds the supply duct (25), extends from the rear bulkhead (20) to the forward bulkhead (19) and forms an annular space between the protective shroud duct (31) and the supply duct (25). The annular space is closed off at its rear end at the rear bulkhead (20) and throughout its length within the rear compartment (18) by the protective shroud duct (31) and is open at its forward end to provide gaseous flow communication with the forward compartment (17), whereby leakage of hot gases from the supply duct (25) upon rupture are prevented by the protective shroud duct (31) from entering into the rear compartment (18) and pass into the forward compartment (17). A discharge duct is provided for discharging spent gases from the forward compartment (17) to atmosphere.

Title: Blind spot sensor scanner
Inventor: MARFORI ENRIQUE G
IPC: G01S13/931
Filed: 1993-08-23
Abstract: ABSTRACT      A simple and inexpensive search radar installed in a convenient position to a motor vehicle, a novel scheme purposely to caution the driver at all times when there is another vehicle or other obstacle on the driver's left side or right side blind spot portion of the road. Although the above device and many other patents dealing with the subject are known to exist, no device of the types disclosed is known to have become the standard of commerce, for whatever reason or combination of reasons: lack of foresight, lack of efficiency, complexity, weight, cost, objectionable appearance. Currently, motor vehicle drivers on the high-way are dependent to their rear and side view mirrors to check overtaking vehicles on their left or right lanes but the views reflected from the mirrors do not cover the driver's blind spot portion of the road. Without this radar device a split-second mistake to change lane unaware of an overtaking vehicle on their blind spot portion of the road may result to a crucial if not a fatal accident. An absolute knowledge of what lurks in the blind spot areas while the vehicle is in motion, will make the driver at ease likewise enhance their driving concen-tration. Incidentally, unseen during foggy weather, an astray oncoming vehicle likewise can be warned of an impending accident. This invention is substantially envisioned to prevent avoidable and costly accidents.

Title: Spinnner for producing fibers by centrifugation of molten mineral material shaped as a single crystal coating and process for its manufacture
Inventor: BERNARD JEAN L
IPC: C03B37/04
Filed: 1993-02-05
Abstract: A metal component like a spinner for producing mineral wool material consists of or at least comprises a unitary cast piece of metal superalloy preferably on the basis of nickel or cobalt, which unitary cast piece is in the form of a single crystal. The component may be produced in a receptacle (11) consisting of a lower crystal forming chamber (12) and an upper workpiece forming chamber (15) connected by a single crystal selecting constriction (16), or starter, so as, in combination with suitable heating means (20) and drawing speed, to allow drawing of a single crystal to form all of the unitary cast workpiece in the cavity (19) of the mould or receptacle (11). The single crystal is significantly more corrosion resistant than the same material of poly-crystal structure. The capability of sustaining higher strain at high temperature before creep rupture after 1000 h on the one hand, and the high ductility leading to a more even stress distribution within the material and avoiding stress peaks on the other hand cooperate to make a spinner of the invention best suited for operation at high temperatures as they are preferred in the fiberization of rock wool like basalt by internal centrifugation.

Title: Compact surgical illumination system capable of dynamically adjusting the resulting field of illumination
Inventor: LI KENNETH
IPC: F21V14/06
Filed: 1995-01-04
Abstract: The present invention provides a compact surgical headlamp capable of dynamic adjustment of the resulting field of illumination, comprising at least a single core fiber optic delivery light guide, an adjustable light projection system, and a mounting mechanism for movably supporting the headlamp proximate to the surgeon's eyes. A receiving block is also provided for supporting the structure of the projection system and for coupling the delivery fiber thereto. The projection system comprises a cylindrical housing mount adapted with a centrally disposed cylindrical cavity for receiving the ferruled, output end of the delivery fiber and for allowing the light output therefrom to initially diverge within the cavity of the housing mount. An outside surface of the housing mount is threaded for screwable reception of a correspondingly threaded, cylindrical lens housing, with a field lens disposed at a distal end of the lens housing such that the lens is movable back and forth along the optical axis of the delivery fiber by screwing the lens housing on and off of the housing mount. The enclosed cavity collects the more divergent light rays and redirects them toward the output endface of the lens so as to produce a concentrated light beam which defines a smaller solid angle of divergence. As a result, a brighter field of illumination is achieved through movement of the lens towards the protracted position where the illuminated field is made smaller. The mounting mechanism comprises a ball and socket joint coupled at one end to a lower corner of the receiving block, and at a second end to a bracket which can easily be attached to an annular head mount for detachable insertion of the head mount into a headband worn by a surgeon.
