Abstract: A blind pressure pilot apparatus provides a supportive base having a pressure responsive bourdon tube mounted on the base for sensing pressure within a connected test vessel. A pair of indicating arms are movably mounted on the bourdon tube upon a shaft mount which is attached to the bourdon tube and generates a rotation of the shaft responsive to pressure changes in the bourdon tube and the test vessel. Changes in pressure produce pivotal movement of each indicating arm which arms can be spaced to cover a desired span. A gap sensor is mounted upon the supportive base and provides a gap having a continuous stream of instrumentation gas flowing across the gap. During pivotal movement, each of the indicating arms generates an arcuate path, a portion of which intersects the gap and flowing stream of instrumentation gas. During such interruption, the flow of instrumentation gas is halted, which can produce desirable signals for operating valves, and performing like pneumatic instrumentation tasks.

Abstract: A venous cannula apparatus is comprised of a fluid conveying tube, the tube providing an upper tube portion which communicates with a pair of lower connected tube branch members. Each of the lower tube branches is normally in an angular position with respect to the upper tube, thus allowing the tube branches to coincide with the atrium, superior vena cava and inferior vena cava during an operation requiring a cardio pulmonary bypass. In the preferred embodiment, two flexible lower branch members are provided forming a "wye" or "tee" with the upper tube portion. The entire cannula structure is manufactured of a material having a "memory" so that after a flexure of the branch members, they return to their operative or normal "tee" or "wye" position. A substantially stiffened sleeve member is cooperatively associated with and connectable to the fluid conveying tube, the sleeve being slideable about the tube and being capable of urging the lower tube branches into an aligned position with the upper tube portion.

Abstract: A portable system for early detection of leaks from suspect piping fittings, for example, as used on the "Christmas tree" portion of a gas well provides an encapsulating bladder which sealably encapsulates the suspect fitting and collects leaks from the fitting. The apparatus provides, in the preferred embodiment, a bladder which can encase any suspect portion of the Christmas tree (or like piping system), such as for example, the choke jacket or other like fittings where maximum turbulence occurs as when gas or oil mixed with sand flows through the fitting. In the preferred embodiment, the collection of a leak within the bladder causes a regulator to operate a control valve and halt the flow of gas, oil, or like flowing material through the piping system of which the suspect fitting is a part. The system can be applied to any other similar existing and operating piping arrangement where the detection of leaks from suspect fittings is desirable.

Abstract: A Kelly Bushing Guard is comprised of an outer protective guarding shell which coverably mounts on the kelly bushing portion of a drilling apparatus. The outer shell is comprised of an upper smaller shell section which is mountable on the kelly bushing itself, there being provided an upper opening through the upper shell portion allowing the passage of the kelly therethrough. A lower shell section is integrally attached to the upper shell section, the lower shell section coverably registering with and guarding the rotary table portion of a well drilling apparatus. An improved cushioned mounting is provided which can be in the form of a plurality of pliable rubberized rings. The larger lower shell section provides a free space under the upper shell section which free space allows the kelly bushing to freely rotate therewithin.

Abstract: A radiopaque blood vessel marker is provided for attachment to the side wall portions of a blood vessel during, for example, a coronary by-pass operation. The markers in the preferred embodiment are flattened, oval-shaped radiopaque discs which are attached to the outer peripheral wall portion of the blood vessel at one hundred eighty degrees (180.degree.) with respect to one another (See FIG. 3). Each radiopaque marker can be comprised of a central imbedded element of radiopaque material such as tantilum which is surrounded by a suitable plastic or like resinous material which is inert and acceptable for use within the human body. During a coronary by-pass, for example, these markers could be attached by suturing or like means to the vein graft which is itself sutured into its new position during the by-pass operation.

Abstract: A multi-compartment cosmetic container is comprised of an upper and lower case, there being provided an inner container to one case into which a desired cosmetic product can be placed. The container can be used to hold a variety of cosmetic products, preferably those which are applied by means of the finger tips. The other case portion provides a sponge like surface for retaining a suitable cosmetic remover. The individual can drag her finger across the surface and remove any excess make-up or like cosmetic which may have accumulated during application. The first and second case can be attachable together in a suitable fashion which separates the two products, but nevertheless retains them in an individual overall container.

Abstract: A method and apparatus for forming dental matrices and copings is disclosed. The apparatus provides a first and a second compression member, each of which is provided with a pliable surface thereon. One of the compression members has a point for the attachment of a conventionally formed tooth die thereto, upon which a sheet of conventional coping material can be placed. The compression members are attachable to a jacking apparatus which imparts relative motion to the two compression members urging them together and compressing the tooth die therebetween the sheet of coping material conforming to the shape of the tooth die itself. In the method of the present invention, the first and second compression members are placed a distance apart, and the tooth die attached to one of the compression members at its pliable surface.

Abstract: A straight edge level is provided which is comprised of a level body having a plurality of conventional leveling bubbles thereon, and a sliding scale member which is extendable from but substantially planar the level body itself. In the preferred embodiment, a scale is provided on the surface of the level body, and a second scale provided on the surface of the slide member. In operation, an extension of the slide member will produce a scale reading at the end portion of the level body from which the slide member extends. The scale provided on the level body begins its numerical climb from that same location on the level body. Thus, in operation, the user can add the numbers appearing on the two scales and get a desired overall measurement.
