Title: Foil arrangement for water-borne craft
Inventor: STEWART LEO J
IPC: B63B41/00
Filed: 1987-09-30
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE A water-borne craft includes a hull having a pair of wing-like foils positioned on the bottom of the hull toward the rear or stern portion of the craft and in equally spaced relation on opposite sides of the fore and aft center line or symmetry axis of the hull such that the foils are immersed in the water when in use.  The foils are each arranged so as to be movable between a first position such that they meet the relatively moving water and generate a lifting force which reacts with the hull so as to lift the rear portion of the hull upwardly,and a second position wherein no lifting force is generated by the foil as, for example, during turning motion of the hull.  By exerting the lifting force on the rear portion of the hull, the planing angle is reduced thus reducing hydrodynamic drag and allowing for an increase in speed.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed wherein an ingredient is treated so that it will exhibit a controlled release when incorporated in chewing gum.  According to the method, a quantity of a powdered ingredient is mixed with an agglomerating agent, such as a modified cellulose, and a limited quantity of a solvent for the agglomerating agent, such as water.  The quantity of solvent is limited so as to produce a mixture which is only moist or damp.  This damp mixture is characterized as being dust-free, non-flowing and crumbly.  The damp mixture i  then dried and the dried mixture is treated, e.g. by grinding and/or screening, to produce the desired particle size range in the agglomerated ingredient particles.  These agglomerated particles comprise collections or clusters of ingredient particles which have been bound together by the agglomerating agent.

Title: Ceramic composite and methods of making the same
Inventor: KUSZYK JACK A
IPC: C04B35/65
Filed: 1988-01-11
Granted: 1992-10-20
Abstract: ABSTRACT      There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal with an oxidant, and (2) one or more fillers embedded by the matrix.  The metal alloy and permeable mass of filler having at least one defined surface boundary are oriented  relative to each other so that formation of the oxidation reaction product will occur into said mass of filler and in a direction towards said defined surface boundary.  On heating the metal to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler to said defined surface boundary.  The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of any residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary, thereby producing a self-supporting ceramic composite.

Title: Hydropneumatic gun for setting blind-rivet nuts
Inventor: KAMATA AKIRA
IPC: B21J15/18
Filed: 1988-01-27
Granted: 1992-05-12
Abstract: Abstract The present invention relates to improvements in a hydropneumatic gun for setting blind-rivet nuts used for integrally securing,  for example,  two panels to each other with a nut.  In the hydropneumatic gun for setting blind-rivet nuts, an air piston fitted in an air cylin-der is moved to pressurize oil housed in the gun body, causing an oil piston to be retracted,  so that a screw mandrel attached to the oil piston at its tip is re-tracted to the inner part of the gun body,  thereby to exert a deforming force to a sleeve of a nut threadedly mounted on the screw mandrel. The hydropneumatic gun for setting blind rivet nuts comprises an air motor to be rotated by compressed air,   an air motor driving air guide passage,   an air motor forward/reverse rotation direction changeover mechanism for switching the rota-tion direction of the air motor,  and a power transmis-sion mechanism for transmitting an air motor driving force to the screw mandrel.  According to the present invention,  a series of operations of the screw mandrel such as forward rotation,  stop of the rotation, retrac-tion,  reverse rotation and advancement can be carried out smoothly and sequentially.

Title: Reversing switch assembly for an electric assist steering system
Inventor: HAMMERLE FREDERICK A
IPC: H01H35/12
Filed: 1988-07-29
Granted: 1991-08-06
Abstract: Abstract A switch for controlling the current to an electric motor is disclosed.  The switch includes first and second parts which are relatively rotatable about a first axis The switch also includes contacts which are actuatable to permit electrical power to be applied to the motor in a direction depending upon the direction of relative rotation between the first and second parts.  A portion of the contacts are carried by a rocker arm pivotally mounted against one of the parts with cooperating contacts mounted to the one part.  Actuation of the contacts is controlled by an associated pivoting member located radially outward of the first axis and pivotable about a second axis, transversely to the first axis. The pivoting member carries a roller slidably mounted to an end thereof and resiliently biased against the rocker arm.  The roller is of sufficient diameter to contact the rocker arm at two locations when the switch is in a neutral condition with all the electrical contacts open.  Relative rotation between the first and second parts causes the pivot member to pivot which, in turn, causes the rocker arm to pivot and close a set of contacts.

Title: Process for treatment of rolled steel to increase resistance to corrosion
Inventor: AICHER MAX
IPC: B21B45/08
Filed: 1988-08-31
Granted: 1992-08-18
Abstract: ABSTRACT For application of a coating of a non-ferrous metal, such as for example zinc, on the surface of rolled steel to increase resistance to corrosion it is proposed that the rolling steel be descaled in direct continuation of the rolling process from the rolling heat by the use of water under pressure and directly after descaling, to prevent re-formation of scale, that it be cooled rapidly by the use of water to a temperature suitable for hot application of the coating and that finally the coating be applied.  The advantage of the invention lies on the one hand in the fact that only one single medium, i.e. water, is used for both descaling and prevention of re-formation of scale and at the same time for cooling purposes, where cooling can be carried out such that the rolling heat is utilizable in an ideal manner for the purpose of coating.  This ensures that all process stages or treatment processes can take place in direct continuation of the rolling process, that is to say at rolling speed, so that the finish coated end product leaves the production line in the same way as a normal rolled product, not subjected to aftertreatment.

Title: Cantilevered support arms for plastic bag rack
Inventor: STROH ALVIN L
IPC: B65B67/12
Filed: 1989-03-31
Granted: 1993-08-03
Abstract: ABSTRACT OF THE DISCLOSURE          A two-wire structure for use in suspending plastic bags on a rack is formed by inwardly bending each of the end portions of a single straight length of wire such that each lies against the middle portion thereof with their terminal ends butt welded together and with an upwardly directed looped protuberance formed on each end of the two-wire structure.          Each end portion of the two-wire structure so formed is then bent to provide cantilevered support arms extending at right angles from each end of the middle portion thereof which forms the back of the two-wire structure by which the cantilevered support arms are attached to a rack.  Such a construction provides the upwardly directed looped protuberances for use as safety precautions on the ends of the cantilevered support arms and further assures that each of the cantilevered support arms is provided with a continuous surface throughout its length.  Such a continuous surface is needed to enable small mounting holes punched on the side handles of a stack of plastic bags in a flattened condition to pass over the end protuberances and slide along the cantilevered support arms during the storing and individual opening of the plastic bags in the stack.
