Abstract: An addressable electronic switch which switches power to an electromechanical device upon detection of an individual access code in a serial data stream. The addressable switch is capable of series connection with a host computer and other peripheral devices. The switch circuit receives a serial data stream containing access code information for one or more of such switches as well as data to be transmitted to another peripheral device, detects the presence of an individual access code within the data stream and causes a switching action in response thereto, and retransmits all data except its own detected access code.

Abstract: A valve assembly for use in for example a stirrup pump. The valve assembly has a body defining a bore into which a carrier is inserted. The carrier defines a tubular passageway with a pair of O-rings spaced apart along the length of that passageway. The passageway is of substantially uniform internal diameter and the O-rings are received in annular grooves formed in the inside surface of the passageway. Two balls are provided each associated with one of the O-rings and an inlet port is provided which communicates with the space in the passageway between the O-rings. The application of an excess pressure to the port drives fluid from the port through one of the O-rings whereas the application of a reduced pressure to the port draws fluid through the other O-ring to the port.

Abstract: Described briefly, according to a typical embodiment of the present invention, a breathing mask is provided which has the intake air heater and heat and moisture exchange media located below the nose and situated for minimum exposure to heat transfer to the exterior. The mounting thereof is somewhat cantilevered from the mask, to minimize direct heat transfer to the exterior. Electric heating element means are provided and supplied from an energy pack mounted in the mask itself at a relatively low level. Some of the inhaled air passes through a first filter and moisture collecting medium to the mouth and/or nose of the individual wearing the mask. All inhaled air passes through a heat exchanger and a second filter and moisture exchanger. A valve is provided so that all air exhaled during normal respiration passes through both of the moisture exchangers.

Abstract: A plurality of resilient wires interconnected at their respective ends form a collapsible filter basket adapted to be introduced into a blood vessel of a patient. The basket in its expanded and relaxed state forms an apertured, elongate solid of revolution with pointed ends and has a base as measured between the pointed ends at least equal to the maximum diameter thereof. The design of the filter basket of the present invention facilitates insertion and adjustment of position or orientation once inserted and allows large masses of emboli to build up without seriously restricting the free area available for blood flow through the filter.

Abstract: A vented, nestable-extendable pouring spout for use with a container having an opening therein includes an annular mounting portion adapted to be secured to an annular lip encompassing the opening of the container. A generally funnel shaped flexible body portion is secured at its larger circumferential edge to the mounting portion and at its smaller circumferential edge to a tubular neck portion located inwardly of the mounting portion. The body portion has an invertible fold portion adjacent the mounting portion to which is attached a plurality of circumferentially spaced ears, each ear having a pair of cylindrically shaped nibs extending therefrom. In the nested orientation of the spout, the ears extend downwardly out of the way of the nested neck and body portions. As the spout is extended, causing the invertible fold portion to invert, each ear rotates inwardly about its point of attachment until the ears extend inwardly perpendicular to the longitudinal axis of the spout.

Abstract: A tell-tale wear monitor for pipes having wear resistant inner linings. A plurality of wear monitors is provided spaced apart along the length of a pipe section or spool and angularly spaced apart about the pipe circumference. Each of the wear monitors includes a plug member attached to the outer pipe casing and covering a tell-tale hole which extends through the pipe casing. The plug members are made of a material which, relative to the inner lining material, is readily worn away by abrasive contact with the material conveyed within the pipe. When the plug member is worn through, fluid flow is permitted through the tell-tale hole. The wear monitor provides a means for determining when maintenance of the pipe section should be scheduled and allows for extended useful life of the pipe section.

The plate includes a pair of legs extending on opposite of the tongue mouth and into the main body transferring plate load into the main body of the buckle. The push button includes two legs fitting adjacent and inward of two arms of the latch in turn limiting outward travel of the button legs. An alternate embodiment includes a third leg depending from the plate.

Abstract: A color-sensitive currency verifier operating with a plurality of narrowband light sources optically coupled to a single broadband photodetector and including means for automatically balancing the color outputs of the various light sources. Color balancing is accomplished just prior to the examination of a specimen bill. The data samples are taken under the control of a microprocessor and used to authenticate the specimen bill both on the basis of pattern and color information stored in memory. Multiple data samples from a single target area are divided to compensate for soiling condition of the bill, and further compensation for condition of the bill is provided by adjusting the conversion scale factor of an A/D converter on the basis of data samples taken from a reference target area on the surface of the specimen bill before test or data samples are taken.

Abstract: A pivot fastener construction useful in coupling two parts. The pivot fastener prevents unwanted separation of the parts coupled while permitting the parts to rotate relative to each other. The blind pivot fastener has bushing members which can be secured in fixed relationship to the parts coupled by threading, press fitting, expansion fitting or the like. The advantages of the construction may be utilized in both assembled and unassembled pivot fasteners. By changing specific aspects of the design, such as assembled/unassembled, means of securing the bushing members, use of a separate bearing post member, etc. the specific construction may be altered in response to specific application needs.

Abstract: An anchor retriever for deploying an anchor from a boat into the water and for retrieving the anchor from the water includes a base portion having a metal plate for attachment directly to the boat and a synthetic material guide providing a sliding channel arrangement for a movable carriage. Pivotally attached to the movable carriage is an anchor retention assembly which provides the actual anchor holder portion which pivots from a substantially horizontal to a substantially vertical orientation as the anchor goes from a stowed orientation to a deployed orientation into the water. When the anchor is retrieved it applies force on certain portions of the retriever assembly, these portions are then allowed to come out of locking engagement whereby the anchor retention assembly pivots from its vertical orientation to its horizontal orientation as it goes from a deployed condition to a stowed condition.

Abstract: A roller assembly for mounting carriages to rails is provided with a clamp having a pair of jaws securable to the rail by a handwheel. The length of bearing of the jaws on the rail is relatively small so that, upon loading a clamped assembly in a direction tending to move it along the rail, the clamp will rotate into tighter biting engagement with the rail to prevent slippage thereon. Release is achieved, even after the biting action, by positive separation of the jaws in response to loosening rotation of the handwheel with screw thread action driving the jaws apart from each other and from the rail.

A window in the sleeve forms a stop surface through which a projection on the other distal end extends limiting the amount of relative motion between the cross frames.

Abstract: Disclosed is an open-back restraining vest having posterior wings which overlap in back to close the vest. Attached to the end of each posterior wing is a tie-strap, one of which is disposed through a loop on the exterior of the other posterior wing, the other tie-strap being disposed through a slot in the first posterior wing, whereby the application of tension to the tie-straps serves to draw the vest closed. The tie-straps are anchored to the rails of a bed, the amount of slack determining the limits of the patient's range of movement. Additional monitor straps attached to the vest may be connected to an alarm to indicate when the patient is approaching the limit of his permissible range of movement.
