Title: Continuous-use molten metal inclusion sensor
Inventor: GUTHRIE RODERICK I L
IPC: G01N15/12
Filed: 1990-04-27
Abstract: A molten metal inclusion sensor intended for "continuous" use in the testing of steel, i.e. a useful life of at least about 30 minutes, comprises a probe which is detachably connected to a water-cooled support member (35). The probe comprises a tube (30) of heat resistant material, preferably silica, having an inner electrode (31) mounted on its interior wall and an outer electrode (32) mounted on its exterior wall, the molten metal entering the tube interior through an orifice (33) upon its immersion in the molten metal, whereupon the flow of metal with entrained inclusions is monitored by measuring the voltage between the electrodes (31, 32). The electrodes (31, 32) are preferably of graphite and are shaped to fit closely against the walls of the part of the tube (30) that is immersed in the metal and are of a material that retains enough mechanical strength to support the tube (30) as the metal is pumped into and out of interior, the metal remaining hot enough for this pumping to occur. The orifice (33) is contoured to produce streamline flow and the Reynolds number of the flow preferably is kept below 2000.

Title: Method of controlling pedestrian and vehicular traffic flow
Inventor: RASWANT SUBHASH
IPC: G08G1/08
Filed: 1991-11-04
Abstract: Abstract of the Disclosure A system for controlling vehicles and pedestrians on intersecting one-way roadways.   Vehicles on a first one-way street are  only allowed, with a "go" signal to either cross the intersection and continue on the street or to turn onto the intersecting one-way street.  The vehicles on the intersecting, second one-way street are stopped while vehicles on the first street are moving.  During this time pedestrians are allowed to cross in front of the stopped vehicles on the second one-way street.   Then, when the light changes, the vehicle traffic on the second one-way street are only allowed to turn onto the first one-way street, i.e., they are blocked from crossing the intersection and continuing onto the second one-way street.          During this time,  the vehicles on the first one-way street are blocked, too,  from entering the intersection.   During this time, pedestrians may cross between adjacent corners to the stopped vehicles on the first one-way street and, at the same time, between opposite corners of the second one-way street, downstream of the portion of the intersection.  Intermodal conflict or friction is this eliminated.

Title: Electronic level control system minimizing level variation of liquid in a reservoir
Inventor: BOUDREAULT GUY
IPC: G05D9/12
Filed: 1991-11-29
Abstract: Abstract An electronic level control system for minimizing level variations of liquid in a reservoir. The system comprises an inverted cup, a housing for the cup, for slidably moun-ting the cup.  The housing is provided at its top with an aperture and at its lower portion with a liquid inlet for communicating into the cup a liquid from a reservoir in which the liquid level variations are to be minimized.  The cup, at its top, is provided with a stem projected upwardly and through the aperture of the top of the housing, whereby the stem is slidable through the aperture.  In space relation to the end portion of the stem, a switch is operable by the end portion of the stem.  Thus a liquid in the reservoir to be fed through the liquid inlet of the housing rises within the cup thereby raising the cup. When a targeted level is rea-ched the cup and correspondingly the end portion of the stem are in their uppermost position. The end portion of the stem actuates the switch.

Title: N-aryl and n-cycloalkyl neoalkanamide insect repellents
Inventor: STELTENKAMP ROBERT J
IPC: A61K8/00
Filed: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE:           N-monosubstituted neoalkanamides of 11 to 14 carbon atoms wherein the substituent on the amide nitrogen is cyclic (aromatic or cycloaliphatic, such as aryl or cycloalkyl) and of at least five carbon atoms, have been discovered to be insect repellent, providing that any aromatic substituent is unsubstituted at the ortho position and that when the neoalkanoyl moiety is pivaloyl the total number of carbon atoms in the N-cyclic neoalkanamide is at least 12.  Such neoalkanamides are useful as repellents against cockroaches, including American, German and Oriental cockroaches, and are also effective against mosquitoes (both Anopheles and Aedes), black flies and carpenter ants, and to some extent against deer ticks.  They may be applied to areas, locations and items which are desirably to be kept free of such insects, with applications being direct or of solutions or emulsions thereof, preferably by spraying, or in detergent compositions or other products to be applied to such areas, etc.  Because the described neoalkanamides are desir-ably substantive to surfaces and are usually in liquid state, they give long lasting repellency to such areas, etc., and tests have shown them to be sufficiently long lasting.

Title: Recovery of floating liquid
Inventor: BURT DAVID A
IPC: E02B15/04
Filed: 1990-11-06
Abstract: A skimmer device for recovering a first liquid which is floating on a second liquid, e.g. oil on water, uses one or more discs (10) rotating in a plane transverse to the liquid surface (preferably inclined at 70· or less to the liquid surface). Particular benefits accrue, especially when operating in open water, when an inclination angle of 45· or less is used. With a disc inclination angle of 25-30· to the liquid surface a near optimal compromise is reached between oil take-up rate and ease of collection. Further advantages are obtained with skimmer discs of polymethyl methacrylate resin.

Abstract: DRIVE SOCKET     ABSTRACT     A drive socket for driving a fastener having a head into a workpiece, constructed according to the teachings of the present invention, comprises a movable member having a socket and a sleeve having a bottom end. The movable or socket member is capable of axial movement with respect to a surrounding sleeve. An actuable member connects the movable member to the sleeve. The socket member is offset a distance upwardly from the bottom end of the sleeve.  The actuable member positively restricts the axial movement of the movable member with respect to the sleeve so as to permit changing of the distance between the socket and the bottom end of the sleeve from a distance somewhat larger than an axial thickness of the head of the fastener to a distance substantially equal to the thickness of the head in order to fully seat the fastener in the workpiece.
