Abstract: A device for removing a contaminant from a fluid stream flowing within a conduit is disclosed. The device includes a container and a barrier. The container has a first wall generated about an axis and a second wall generated about the same axis. The first wall defines a first volume therewithin, while the first and second walls define an annular second volume therebetween. Both the first and second volumes are sealed at one end of the device, while at the other end of the device the second volume only is sealed. A filter material occupies the second volume. The first and second walls are permeable to the fluid stream and are capable of retaining the filter material in the second volume. The barrier is impermeable to the fluid stream and creates a seal between the second wall and the conduit wall.

Abstract: A dual concentric poppet valve assembly (44) includes an assembled body (45) having an opening (55) therethrough and having a sealing surface (56) surrounding the opening. A first member (46) is mounted in the body opening for axial movement relative to the body. The first member has a first sealing surface (70) arranged to be moved toward and away from the body sealing surface (56) to define a first variable-area orifice (96) therebetween. The first member has a concentric opening (72) therethrough and has a second sealing surface (71) surrounding the first member opening. A second member (48) is mounted in the first member opening for co-axial movement relative to the first member. The second member has a sealing surface (83) arranged to be moved toward and away from the first member second sealing surface (71) to define a second variable-area orifice (98) therebetween.

Abstract: A ball-valve for precise and accurate sampling and dispensing is disclosed. The ball-valve includes a body having a through-bore having a first end and a second end lined with a two-part sleeve which partially surrounds a ball. The ball is rotatably mounted within the sleeve and in sealing engagement with the sleeve. The ball includes a blind-bore of a known volume. The ball rotates between a first position, in which the blind-bore registers with the first end, and a second position, in which the blind-bore registers with the second end. Rotation of the ball transports a known volume from communication with the first end to communication with the second end. The sealing engagement between the ball and sleeve will prevent depressurization through the ball-valve of a vessel mounted to the ball-valve, both when the ball is at rest and when rotating. In addition, the sealing engagement between the ball and sleeve ensures only the desired volume of fluid is transported between the first and second positions.

Abstract: Structure for evaluating the efficacy of sterilization apparatus using either steam or ethylene oxide as sterilant is disclosed. The structure includes an insert of porous material having a cavity formed therethrough for retaining a biological or chemical indicator. The porous material has homogeneous porosity throughout. The insert of porous material and indicator are enclosed within an outer covering which is relatively impervious to penetration of gases and which provides restricted pathways to air and sterilant. The outer covering is provided with removable portions which are removed when the structure is used to evaluate ethylene oxide sterilization. Removal of the portions enlarges the existing pathways for ingress and egress of gases which may be appropriate in certain efficacy testing.

Abstract: A personal cleansing composition, suitable for use as a soap or a shampoo, contains at least one conditioning agent, such as silicone. The composition also contains a refined agricultural grain, such as oats, that has been at least partially defatted and that has at least some of its bran removed. The conditioning agent is carried by the grain, and is substantially insoluble in the wetted composition.

Abstract: The invention is directed to an improved electromagnetic force motor (10) with internal eddy current damping. In the preferred embodiment, the motor is comprised of a body (11), a pair of permanent magnets (15.sub.L, 15.sub.R), an electromagnetic coil (20), and an armature (13). The armature is positioned with respect to the body so as to define two variable-reluctance working air gaps (30, 31) and a constant-reluctance non-working air gap (29). The permanent magnets face one another and are mounted on the body. The body and armature are both adapted to conduct magnetic flux. Each working air gap contains a magnetic flux that is the algebraic sum of a flux attributable to the permanent magnets and a flux attributable to the coil. The non-working air gap contains flux attributable only to the permanent magnets. A current-conducting member (14) is attached to the armature and positioned within the non-working air gap.

Abstract: An improved method of moving a rotary fixture (20) from a first angular position to a second angular position includes the steps of: providing a body (25); mounting the fixture on the body for rotational movement about an axis (x--x); mounting a pin (23) in the spindle (22) of a machine tool; moving the pin so as to engage the fixture at a location eccentric to the axis; and selectively moving the pin relative to the axis from one location to another; thereby to rotate the fixture from the first angular position to the second angular position.

Abstract: A device (20) for providing a uniformly-variable orifice includes an object (21) having an outer surface, a wall (24) surrounding the object in spaced relation to the outer surface and defining an annular orifice therebetween; and deforming means (F.sub.1) for causing at least one of the surface and wall to move perpendicularly and uniformly toward the other of the surface and wall without substantially altering the geometric shape of the annular orifice, whereby the movable member may be moved relative to the other to vary the area of the orifice. In the preferred embodiment, the area of the orifice varies substantially linearly with application of the deforming displacement.

Abstract: A round bangle (20) has an improved clevis-like hinge assembly (23) and an improved bangle closing mechanism (24). The hinge assembly is in the form of two end caps, which are operatively mounted on adjacent marginal end portions of the bangle halves. A clevis-type connection is recessed in one of the bangle halves such that there is the appearance of a generally smooth continuous exterior when the bangle is closed. The improved closing mechanism includes a keeper wire (42) extending outwardly from one of the bangles within the other, with an intermediate support ball (43) and a distal button (44) located on the keeper wire. When the bangle is closed, the button passes through an opening (45) in the other bangle half to releasably lock the bangle halves together.

Abstract: The present invention provides an improved hot gas control valve (20) which is adapted to apportion a gas flow, such as that issuing from a solid propellent gas generator, among a plurality of outlets communicating with rocket thruster nozzles (36). The improved valve has a body (21) and a valve member (22). The body has an inlet (24) communicating with an internal cavity. The cavity is partially bounded by a partially-spherical concave surface (32). The body has a plurality of outlet passages terminating in ports at the concave body surface. The valve member is operatively arranged within the cavity for omni-directional pivotal movement therewithin. The valve member has a surface (40) sealingly engaging the body concave surface and terminating in an edge (41). This valve member edge cooperates with the body ports to form variable-area metering orifices (A, B, C and D) therebetween.

Abstract: A universal tactical mount (10) is adapted to attach to a firearm barrel (18) and to have a plurality of firearm accessories (41, 42 and 43) mounted to it. The universal tactical comprises a plate (11) divided into an upper portion (12) and a lower portion (13) and an opening (16) on the boundary between the portions sized to tightly circumscribe the firearm barrel, thus fixedly mounting the universal tactical mount to the firearm. The plate further includes at least one mounting station (30, 31 and 32) adapted to fixedly hold a firearm accessory, such as a light source (e.g., laser, visible light or infra-red).

Abstract: A self-tightening side lock (20) for a roll-up door includes a keeper (25) mounted on the jamb, and a latch member (26) pivotally mounted on a door panel. The latch member is selectively cooperable with a catch (30) to hold the door in a closed position. The latch member is biased to move in a counter-clockwise direction. The latch member is adapted to be moved in a clockwise direction, against the opposing bias or a spring 42, to an out-of-the-way position at which the displaced latch may pass by the catch. The latch member has a side cam surface (33) arranged to engage the catch (30) when the door is lowered and to cause the latch member to pivot in a clockwise direction toward the out-of-the-way position to allow the latch member to pass by the catch. The latch member also has an upper cam surface (34) arranged to engage the catch such that the counter-clockwise movement of the latch member will cause the door to be self-tightening.

Abstract: A toy vehicle (10) emulating more than one function of an adult vehicle utilizes a novel chassis, The chassis includes at least two portions (11 and 12) hinged together at a pivot rod (13). The pivot rod may be raised or lowered placing the toy vehicle in at least a first and second position. The toy vehicle may perform one function in its first position and a second function in its second position, each junction emulating the actions performed by an adult work vehicle. A stop (25) is incorporated to the chassis to define maximum and minimum positions for the pivot rod.

Abstract: A transducer (23) for producing a digital output signal proportional to a change in a sensed physical parameter includes first and second pairs of series-connected resistors (24, 25 or 26, 28). The electrical resistance of at least one of these resistors is variable in response to a change in the sensed parameter. The transducer also includes sine wave generators (31, 32) for applying first and second sine waves across the first and second pairs, respectively. However, these first and second exciting voltages are phase-shifted relative to one another by a constant phase angle. The voltages between the resistors of each pair are vector-summed. The phase angle of this vector-sEed signal is compared with the phase of the reference sine wave, and a pulse-width-modulated waveform is produced.

Abstract: An improved pressure regulator (60) is provided with an eductive flow to maintain the outlet pressure at increased flows through the regulator. The improved regulator broadly includes a body (61) provided with a bore. A valve seat (24) is movably mounted in the bore to provide a valve seat. A valve member (68) is mounted in the body bore for controlled movement toward and away from the seat to vary the area of a main orifice through which fluid is adapted to flow from an inlet to an outlet. The body has a sensing passage (73) communicating a portion (76) of the bore with the exit passage (65). The facing surfaces (74, 76) of the bore and valve member are so dimensioned and configured as to provide an elongated open-ended annular space (78) therebetween that extends along the guide passage from its communicative intersection with the exit passage to a point beyond which the sensing passage communicates with the guide passage.

Abstract: An improved heater facsimile temperature detector (47) has an increased dynamic responsiveness in measuring temperature changes. The improved HFTD (47) reduces the amount of mass surrounding the thermocouple tip, thus, reducing the time lag caused by the intervening heating or cooling of this material before the temperature change can affect the thermocouple. The thermocouple (69) is welded to a body (59) extending beyond a machined flat (54) on the outer surface of an intermediate portion (49) of the HFTD. The body does not extend beyond the outer surface (51) of the intermediate portion.

Abstract: Compression and distortion on a wax pattern during curing are eliminated by employing a thermochromatic dye which changes color when investment material sets. By monitoring the dye, the set investment material can be removed from the assembly before curing, eliminating compression forces on the wax pattern from the exothermic curing process expanding the investment material against the constraints of the assembly.

Abstract: A valve insert (40) is adapted to be removably mounted as a unit on a cylinder valve (41) to selectively enable a flow of fluid therethrough when a male coupling section (52) is inserted into the outlet of the cylinder valve. The improved insert includes a tubular body (55), a valve member (58) mounted for sealed sliding movement relative to the body, biasing means (97) and a docking member (59) mounted on the valve element and adapted to engage the nose of the male section. When the male section engages the insert and displaces a sealing cushion (80) off its seat (72), the pressure of fluid will urge the valve element (58) into tighter sealed engagement with the male section.
