Filed: 1987-01-30
Granted: 1991-08-13
Abstract: ABSTRACT            A small lubricant testing device which has a rotor to which a small electric hand drill can be attached for driving during a simple test to establish the relative amount of pressure which has to be applied to a member having a small contact area pushed against an outer surface of the rotor.  The testing device, which can be readily carried by a salesman for the purposes of demonstrating the relative strength of a lubricating film produced by a particular liquid lubricant or an additive, includes a receptacle for receiving the sample lubricant to a level to contact the surface of the rotor.  A handle, against which a force by hand may be exerted to increase the pressure applied by the contact area to the surface of the rotor, is designed to flex relative to a indicator rod so that a reading can be obtained when the pressure applied is sufficient to stall the drive by  the drill  and thus indicated a point at which the lubricant has failed to maintain a lubricating film over the rotor surface.  The reading can be compared to a reading conducted in the same manner on another lubricant or additive.

Title: Apparatus and method for fragmenting slag
Inventor: SAVILLE JAMES
IPC: C21B3/08
Filed: 1987-08-13
Granted: 1991-02-19
Abstract: ABSTRACT         Apparatus and method for handling molten slag, in which the slag is delivered from a furnace to a cooling conveyor by a reciprocating spout, driven in a horizontal plane to provide a stream of molten slag in a substantially sinusoidal pattern to the conveyor.  The conveyor is sloped to provide gravity flow from an input end to an output end, and vibration is imparted to the conveyor for separating the molten stream of slag into pieces of slag and for propelling slag from the input end toward the output end. Cooling is provided by a water jacket around the sides and bottom of the conveyor, sufficient substantially to solidify the pieces of slag before they reach the output end.  Further cooling may be provided by a spray bar, positioned above the conveyor, which provides a stream of cooling water to the surface of the slag.  A water bath is disposed to receive pieces of slag dispensed from the output end of the conveyor, further cooling the slag to about 200 degrees Centigrade. Pieces of slag are then received into a screw conveyor, which simultaneously conveys the slag for further processing and reduces the size of individual pieces. A divider may be positioned within the conveyor to assist the vibratory means in separating the molten stream of slag into pieces of slag, suitable for handling.

Granted: 1995-05-30
Abstract: Polyvinyl chloride resins and copolymers thereof are produced containing little or no get content, commonly referred to as "fisheyes", even after numerous charges to a reaction vessel without cleaning thereof between charges. A primary dispersant system such as a high hydrolyzed polyvinyl acetate and an optional modified cellulose ether are utilized in association with a low hydrolyzed secondary dispersant, for example, polyvinyl acetate, in the reaction vessel such as a polymerizer containing an aromatic inhibitor polymer build-up compound coated on the internal walls thereof.  The resin particles produced tend to have a uniform particle size and a high porosity so that plasticizers can readily be incorporated therein.  Since contamination buildup on the reaction vessel walls is reduced or prevented, the amount of gel is reduced and production rate is increased since, as noted above, cleaning of the vessels is not required.

Title: Cardiac valve prosthesis
Inventor: KNOCH MARTIN
IPC: A61F2/24
Filed: 1988-01-20
Granted: 1992-03-10
Abstract: ABSTRACT                Cardiac Valve Prosthesis The   mechanical   cardiac   valve   prostheses   used conventionally comprise a tiltable valvular closing body pivotally supported in a valve ring  (10) whose shape  is  substantially  determined  by  the  closing geometry of the closing body. Due to the shape of the inner face of the valve ring, vortices may develop in flowing blood which, at the boundary of the discharged jet, may reduce the blood velocity in flow direction, on  the  one  hand,  and  which  may  favor  thrombus formation and blood damaging shearing stress on the other hand. The flow resistance caused by the valve ring is relatively high due to the occurring flow separation in the valve ring and the resultant jet contraction.      In  case  of  the  cardiac  valve  prosthesis  of  the invention, the inner area (10a) of the valve ring (10) has an opening cross section continuously decreasing in flow direction, the valve ring being shaped like a nozzle, and a flow disrupture only occurring at the nozzle end allowing a concentric flow discharge, while a vortex formation at the jet boundary and inside the flow is inhibited to a far extent. As a result, flow resistance  is  clearly  reduced and blood  damage  is minimized. Further, the joint (13) is improved in that a flushing channel  (18)  traverses the  joint cavity (16) in order to avoid deposits of blood particles in the valvular joint.             (Fig. 2)

Title: Power door lock interlock circuit
Inventor: HOCK DARRYL A
IPC: B60Q5/00
Filed: 1988-04-20
Granted: 1992-08-25
Abstract: ABSTRACT The power door lock interlock circuit senses the presence of an ignition key in the ignition and also senses when a door is open. When these conditions are met, the power door lock is placed in an interlock condition whereby pressing the power door lock button causes the horn to sound instead of locking the doors.  The circuit is thus useful in preventing the driver from accidentally leaving the ignition key in the ignition and accidentally locking all doors.  All doors may be unlocked in the usual fashion and all doors may be locked in the usual fashion provided the interlock condition has not been met.
