Abstract: A security system including mechanism for detecting intrusion into a building such as a home, mechanism for activating the detecting mechanism, mechanism for turning off the supply of water to the outdoor water outlet, the activating mechanism including mechanism for controlling the shutting off mechanism to prevent supply of water to the outlet when the detecting mechanism has been activated.
Abstract: For direct and on-line study of the physiological states of cell cultures, a robust flow injection system has been designed and interfaced with flow cytometry (FI-FCM). The core of the flow injection system includes a microchamber designed for sample processing. The design of the microchamber allows not only an accurate on-line dilution but also on-line cell fixation, staining, and washing. The flow injection part of the system was tested by monitoring the optical density of a growing E.coli culture on-line using a spectrophotometer. The entire growth curve, from lag phase to stationary phase, was obtained with frequent sampling. The system is thus particularly useful since it operates automatically without direct operator supervision for extended time periods.

Abstract: A lightweight, partially evacuated load-supporting insulation panel comprising an outer gas-impermeable envelope and an inner gas-permeable envelope. The inner envelope is filled with a mixture of coarse gas-permeable granules and fine gas permeable particles, void spaces formed within and between said granules and particles containing a gas of low thermal conductivity. An intermediate gas impermeable envelope may also be used.

Abstract: A cuff measuring device for tailors, including a thumb cap, an elongated portion and a slide, the thumb cap sized to receive the tip of a person's thumb, the elongated portion including indicia for measuring and being joined to the thumb cap and the slide providing a cuff rest and a chalk carriage, the slide being slidably mounted to the elongated portion to adjust the cuff rest against a garment cuff, the chalk carriage, including chalk providing a sliding mechanism for marking the garment for folding or cutting.
Abstract: A golf putter and method is disclosed which allow accurate sighting and positioning of the golf putter head relative to the target or hole, and which has perpendicular elongated teeth that run along the bottom face of the putter head thereby increasing friction and reducing the resultant tendency for the putter head to twist when moving from a rearward optically accurate alignment position to a putting position. The accurate sighting is possible by tilting the golf putter rearward and sighting along the face and top of the putter head. This tilting causes a rear parallel tooth to engage the turf, keeping the putter head in position As the golfer moves from the sighting position.
Abstract: A baby crib bumper for use in a baby's crib such that the bumper pad may remain in place while sheets are changed. A plurality of fasteners and a partial sheet are attached to the bumper pad. The fasteners fasten to the rails of the crib which assists in securing the bumper pads. The partial sheet covers the periphery of the mattress which, also, assists in securing the bumper pad.
Abstract: A humidity control device for use in maintaining a desired humidity, the device including a protective case, a water vapor permeable pouch and a thickened saturated solution, the solution having a suitable humidity control point.
Abstract: A seal for preventing leakage of fluid from between a first member and a second member, the second member is capable of moving toward and away from the first member, the seal is adapted for engaged contact with the first member and the second member so as to prevent leakage of fluid between the first member and the seal and between the second member and the seal, the seal being softer than the second member such that friction between the seal and the second member wears the seal faster than the second member, the seal being adapted to retain a tight seal against the second member as long as the seal has not worn beyond a specified depth; and a conductor for placement about the second member, the conductor being attached to the seal at the specified depth so as to contact the second member when the seal has worn to the specified depth, such that the existence of electrical continuity between the conductor and the second member indicates that the seal requires replacement, the conductor is positionally associat
Abstract: A personal protection apparatus, including uniquely constructed barrier members that may be placed over the hands of the user and then be used for providing medical treatment including application of pressure or for accomplishing the cleanup, and for the cleanup, containment and disposal of infectious and hazardous materials, said personal protection apparatus of the invention being useful in effectively treating trauma victims while at the same time protecting the caregiver from infectious disease, bacteria, micro-organism, viruses, spores and other hazardous contaminants, said apparatus of the invention also being effectively used to safely apply various medicaments, pharmaceutical and other agents to burns, wounds and abrasions and to provide localized cooling to selected areas of a patient's body, said apparatus of the present invention being adapted to remain with the patient thereby substantially limiting the spread of contamination.
Abstract: A personal protection apparatus, including uniquely constructed barrier members that may be placed over the hands of the user and then be used for providing medical treatment including application of pressure or for accomplishing the cleanup, and for the cleanup, containment and disposal of infectious and hazardous materials, useful in effectively treating trauma victims, including sucking chest wound victims, while at the same time protecting the caregiver from infectious disease, bacteria, micro-organism, viruses, spores and other hazardous contaminants, such invention may also be effectively used to safely apply various medicaments, pharmaceutical and other agents to burns, wounds and abrasions and to provide localized cooling to selected areas of a patient's body.
Abstract: An ice fishing rig for retarding reformation of ice and the method of using the same, the ice fishing rig having a heat supply joined to a heat dispensing shaft, an ice fishing line being fed through the heat dispensing shaft, and the heat dispensing shaft being floated adjacent the surface of water in an ice fishing hole.
Abstract: A seal prevents leakage of fluid between the seal and a moving surface. The seal includes a seal body and a conductor. The seal body can undergo wear to a specified depth before the seal requires replacement. The conductor is placed about the moving surface such that wear of the seal body to a specified depth brings the conductor into contact with the moving surface. The conductor may be embedded in the seal body or otherwise attached to position the conductor about the moving surface. Wear of the seal body to a specified depth can be checked by checking electrical continuity of the conductor. The existence of electrical continuity between the conductor and the moving surface may indicate that the seal requires replacement. Alternatively, the conductor may be positioned such that the conductor has worn entirely through when the seal body has worn to a specified depth, with a loss of electrical continuity through the conductor indicating that the seal requires replacement.
Abstract: A selectively floatable minnow bucket, including at least one wall, a gate, a plurality of openings and at least one floatation mechanism, the wall and gate defining a hollow cavity for maintaining live bait, the openings allowing the flow of water in and out of the bucket in order to maintain a fresh water supply to the live bait, and the floatation mechanism including at least one wall, a hollow channel, and plugs or stopcocks, into which substances of various densities such as water, air, or sand are introduced to affect the buoyancy of the minnow bucket.
Abstract: A joint for connecting a first drive shaft to a second drive shaft includes a ball and socket arrangement connecting the two shafts and a spring attached at one end to one shaft and at the other end to the other shaft. The spring is made of a polymer matrix containing fibers made from poly(p-phenylene terephthalamide) resin. The fibers extend through the polymer matrix along the helical axis of the spring. The spring is disposed about the ball and socket arrangement so that shock loads are absorbed by the spring.
