Abstract: A surrogate nursing bib is used by a wearer in promoting bonding with a child. The surrogate nursing bib includes a bib, a first set of VELCRO straps, a second set of VELCRO straps and at least one container. The bib is formed out of latex in order to provide a natural-looking background for the child. The bib has a inner side and an outer side. A cotton lining is disposed on the inner side. At least one pouch is disposed on the outer side. The pouch has an opening. The first set of VELCRO straps is mechanically coupled to the bib in order to secure the bib to the neck of the wearer. The second set of VELCRO straps is mechanically coupled to the bib in order to secure the bib to the waist of the wearer. The container has a nipple on which the child may suckle. The container is disposed in the pouch so that the nipple protrudes through the opening in the pouch.

Abstract: A disposable bib is disclosed. The bib is constructed of a unitary sheet of drapable material. The unitary sheet has opposite top and bottom edges defining a length direction therebetween, and opposite side edges defining a width direction therebetween. A pair of slots extend along opposite side edges of the sheet. The slots define a pair of ties along respective opposite side edges of the sheet for use in securing the bib to a wearer by being tied about the neck.

Abstract: A wing nut with a threaded axial passage is adapted to engage the threads on the horizontal balancing shaft of a wheel balancer having an abutment thereon. A wheel to be balanced is placed on the shaft and is arranged to be held in tight engagement with the abutment when the wing nut is threaded on the shaft. The surface of the wing nut which forces the wheel against the abutment is recessed with a cylindrical recess. A plastic insert is adapted to be retained within the cylindrical recess and has a central bore which is aligned with the threaded passage in the nut to permit the balancing shaft to pass therethrough. The insert projects axially from the nut body so that the insert, rather than the nut body, will engage the member which is holding the wheel against the abutment.

Abstract: A system for sampling material from a remote location which selectively collects a predetermined quantity of material in a valve disposed inside a container. This measured amount of material is transferred to a movable receiving carrier while the receiving carrier is in a sealed relationship with the valve to prevent leakage of the sample material outside the receiving carrier. The movable receiving carrier is transported via an elongated tubular structure to a location remote from the container.

Abstract: A method for avoiding detection by game animals by scent through establishing wind direction to insure that the hunter is positioned downwind from the animal. In the method, a small quantity of a hydrophobic material such as unscented raw talc powder, which may be mixed with a natural masking scent material, is sprayed into the air in a relatively small cloud by means of a hand-held manually operated squeeze bottle. The direction of travel in the air of the cloud of material may then be used to establish wind direction. The material is such as to be undetectable by smell by the animal, and the size and characteristics of the powder cloud is such as to be visually undetectable by the animal at a distance.

Abstract: A fuel injection control apparatus having a pressure detection device for detecting pneumatic pressure in an intake manifold of an internal combustion engine comprises a pressure transducer and a low-pass filter, electrically connected to the transducer, for transmitting an electrical signal from the transducer below a cutoff frequency which is determined to be a frequency equal to or lower than 40 Hz.

Abstract: An inverted tube closely fits a supporting cup and contains a column of water. A substantially annular or ring-like space is formed between the cup and the tube. Water is fed to the annular space through a lateral opening in the tube, the upper edge of the opening being located just below the level of the cup rim. As water evaporates from the exposed ring of water, it is replaced by the inverted column, air being admitted through the tube opening. Evaporation and transpiration causes reduction of the water level thus to indicate the amount of moisture loss from the surrounding soil.

Abstract: A pressure-sensing transducer which can be used to continuously measure the pressure in the cylinder of an internal combustion engine comprising a pressure-transmitting element which includes a generally tubular seat and a metallic plate which closes off a top end of the seat, an M-shaped force-transmitting member which spans across the top end of the seat, the outer legs of the M-shaped member being connected to opposite portions of the top end of the seat and the inner legs being connected to the center of the metallic plate, and a magnetoelastic force-sensing member connected between the outer legs of the M-shaped member, such that pressure-generated forces applied to the metallic plate from within the generally tubular seat are transformed into a tensile force acting on the force-sensing member in a direction perpendicular to the longitudinal axis through the generally tubular seat.

Abstract: A device for accurately measuring core body temperature by measuring urine temperature is disclosed. The device consists of a sampling chamber including an insulated liquid crystal temperature array which will instantaneously display the temperature of the urine sample therein. The device of this invention is useful as an accurate measurement of the fertility cycles in females, and for the detection of ovulation and pregnancy. The device is also useful in the detection of hypoglycemia, hypothermia and fever.

Abstract: A magnetic transducer fits over a rotatable shaft and has a multi-pole magnetic core, one primary winding being wound on half of the poles while a second primary winding is wound on the other half. Direct current pulses are alternately supplied to the two primary windings to provide a-c excitation for producing an alternating magnetic flux or field, adjacent to and within the shaft, which changes as the shaft is torsionally stressed when torque is applied thereto. This stressing causes compression and tension in the shaft which alter the shaft permeability and thus vary the magnetic flux pattern in the shaft. The resulting magnetic field is also a function of the shaft speed due to the shaft's armature reaction, eddy currents being generated in the shaft which develop a counter magnetic field that opposes and distorts the field produced by the two primary windings.

Abstract: This relates to the provision of a vacuum indicator in a container wherein a product is vacuum packaged. Most specifically, an end unit for a conventional container is provided with a vent opening through which air rushes into the container when opened. There is secured to the underside of the end unit a whistle device in communication with the opening so that the inwardly rushing air actuates the whistle device and causes the whistle device to emit a whistling sound in accordance with the vacuum present within the container and thereby gives an audible indication of the freshness of the product.

Abstract: A twin-transducer seismic detector includes a hollow housing closed at each end by a diaphragm-type transducer. A deformable retaining member is pressed against the perimeter of each transducer. An adjustable force is applied to at least one of the deformable members to cause the member to flatten against the transducer. As the deformable member becomes flattened, it reduces the effective area of the transducer and hence alters its compliance and sensitivity. The applied force is adjusted so as to match the sensitivity of one transducer to that of the other transducer.

Abstract: A flow rate meter is proposed which serves to ascertain the quantity of a flowing medium, in particular the quantity of air aspirated via an air intake tube by an internal combustion engine. The flow rate meter includes a measuring body which is pivotable counter to a restoring force about a bearing shaft supported in the housing in accordance with the quantity of the medium flowing therethrough. The flow rate meter further includes a damping body which is likewise pivotable about the bearing shaft and defines a damping chamber in the form of a movable wall, with respect to the flow conduit. The measuring body and the damping body are coupled rigidly to one another by means of crosspieces. The invention comprehends embodiments wherein either the damping body or the measuring body is directly connected with a hub held in a rotationally fixed manner on the bearing shaft.
