Title: Electrostatic resistive stud
Inventor: LIND ROBERT J
IPC: B05B5/053
Filed: 1987-02-25
Granted: 1991-01-22
Abstract: ABSTRACT           A fluid stud and resistor design for electrostatic spray guns has a fluid passage which is shaped like a cloverleaf in cross section.  By providing this cross-sectional shape, the resistor is allowed to reside in one wall of the fluid stud and run, nearly, the complete length of the stud, thereby providing an increased effective resistor length, thus reducing flash-over and providing a smaller contact wire, thereby reducing capacitance.  The design of the fluid needle and electrode is provided so as to reduce the length of the electrode wire, thereby reducing capacitance and allowing an increased diameter wire for increased durability.

Title: Process and an agent for stabilizing tributyltin fungicides for preservation of wood
Inventor: IMSGARD FINN
IPC: B27K/
Filed: 1987-04-10
Granted: 1991-10-15
Abstract: ABSTRACT            Fungicides for preservation of wood, such as tributyltin oxide (TBTO) and tributyltin naphthenate (TBTN), are stabilized through inhibition of a normal autooxidation by addition of up to 1% of at least one metal salt of the formula (I)   wherein R is C4-C16 alkyl, aryl or alkylaryl, optionally substituted with oxygen, nitrogen, sulfur or halogen. R1 is C1-C4 alkyl, n is 0 or 1, and Me is calcium, mag-nesium, nickel, zinc, copper or cadmium when n is 0, and tin when n is 1.            This results in significant inhibition of the degradation of the fungicide which takes place after application to the wood so that the fungicide maintains its activity for an extended period of time.

Title: Nozzle assembly for a vacuum device
Inventor: BERFIELD ROBERT C
IPC: A47L9/02
Filed: 1987-12-07
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE          An arrangement for attaching a rigid vacuum conduit to a nozzle provides high rotational freedom between the nozzle and the rigid conduit while retaining a reasonable degree of airtightness between the conduit and the nozzle.  In one form of the invention, the rigid vacuum conduit includes a coupling section of generally cylindrical form adapted to be received into an inlet opening of the nozzle.  The coupling section includes a plurality of spaced grooves, each circumscribing the coupling section.  The presence of the grooves reduces the frictional loading between the vacuum conduit and the inlet opening while providing a trap for dirt particles that would otherwise jam the vacuum conduit into fixed position in the nozzle.  In a further version of the invention, the rigid vacuum conduit comprises metallic material.  To reduce frictional loading between such metallic material and the inlet opening of the nozzle, an annular band of low friction material encircles a coupling section of the vacuum conduit.  The annular band may comprise a nonmetallic material and may be formed of a pair of cooperating sections.

Abstract: Abstract of the Disclosure An electro-optical sensor for measuring distance to a test surface, such as a road surface beneath a vehicle frame on which the sensor is mounted.  The sensor includes a modulated light source for directing a light beam onto the test surface, and a photosensitive detector for receiving light diffusely deflected from the test surface and providing a pair of output signals  indicative  of  orthogonal  position  coordinates  of reflected light incident on the detector.  The detector outputs are fed to amplifiers for obtaining sum and difference signals which are demodulated synchronously with energization frequency of the light source.  Distance to the test surface is determined as a function of a ratio of the detector output differential to the detector output sum.  In the preferred application of the invention for road profile measurement, a signal indicative of road profile is stored at increments of vehicle motion along the road surface.

Title: Package for crisping the surface of food products in a microwave oven
Inventor: PERRY MICHAEL R
IPC: B65D81/34
Filed: 1988-07-05
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for crisping the surface of a food substance in a microwave oven is disclosed.  A thin film susceptor is positioned close to the surface of a food substance.  The susceptor heats when it is exposed to microwave radiation.  The susceptor preferably is a thin film of metal deposited on a polyester substrate layer. In one embodiment, heating the susceptor causes the polyester layer to shrink, thereby simultaneously creating openings in the susceptor to allow moisture to escape, and breaking the conductivity of the susceptor so that it becomes less responsive to microwave radiation and substantially "turns off."  In an alternative embodiment, passageways are pre-cut in the thin film of metal.  A single surface of the food substance is made crisp in this manner, while the opposed surface is exposed to the micro-wave oven atmosphere.  It has been discovered that a consumer will perceive a food product as crisp if a single surface is made crisp in the manner according to the present invention, and the opposed surface is not soggy or mushy.
