  • Patent number: 4587522
    Abstract: This system provides a warning or alert to persons in vehicles of the presence of emergency vehicles which are emitting audio warning signals. The system converts audio signals to discrete signals, which are also frequency indicative, and then determines whether the discrete frequency indicative signals represent warning signal frequencies. The system also determines whether any warning signal is of sufficient duration to be valid, and if they are, activates the warning device in the vehicle. The warning device may alert the vehicle occupants of emergency vehicles in the vicinity by either audio or visual alarms, or by both.

  • Patent number: 4320940
    Abstract: Optical filtering elements having two opposed surfaces and including at least one thin layer of stable non-reflective fluorescent material provide transparent articles which, when exposed to incident electromagnetic radiation at one surface of the fluorescent layer, absorb certain wavelengths within the fluorescent layer and emit other wavelengths at the opposed surface of the fluorescent layer. In preferred embodiments, when radiation (light) in the visible range (about 400 nm to about 700 nm) is incident on the element from one side, certain wavelengths of radiation which transverse the element are absorbed in the fluorescent layer and other radiation of greater, but also visible wavelengths are emitted from the opposed side without fluorescent light being reflected by the fluorescent layer at the incident side.

  • Patent number: 4318559
    Abstract: An automatic lockable linkage system for use with sliding members, such as a sliding door or window, comprising a first and second telescoping arm member pivotally interconnected adjacent to their inner end portions. Each telescoping arm member also has an outer end which is pivotally connectable to a fixed structure and a sliding member, respectively. When the sliding member is in the closed position, a lockable sliding linkage is automatically positioned over the pivotally interconnected inner end portions of the first and second telescoping arm members retaining the sliding member in the closed position.

  • Patent number: 4303239
    Abstract: The present invention provides a totally adjustable thigh muscle exercise device. The device is totally independent of any other exercise device or structure, is constructed to provide exercise to both the flexor and extensor thigh muscles, and is adjustable as to size, weight and weight location on the thighs so that a single device may be utilized by any user at any amount of weight and for any type of thigh exercise. The device includes a belt, which may be adjusted to any user's waist size and weights suspended from the belt for location at the front of the user's thighs. In preferred embodiments, the location of the weights along the front of the device may be adjusted to accommodate the individual user's needs and the amount of weight may be easily varied. In preferred embodiments, the space between the belt and the weights may also be adjusted to further accommodate the user or the particular exercise being practiced.

  • Patent number: 4279886
    Abstract: It has been determined that ingested vitamin B.sub.12 is bound by R protein in gastric juice, but that it is not capable of absorption in this form. In a system with a normally functioning exocrine pancreas, R protein is degraded by pancreatic proteases in the small intestine, which then allows the B.sub.12 to be transferred and bound to intrinsic factor protein (IF) from which it can be absorbed. This phenomenon serves as the basis for a test for pancreatic exocrine function in which the following compositions are ingested: (1) a complex of IF and B.sub.12 in which the B.sub.12 is labelled; (2) a combination of another binding material, such as R protein, and B.sub.12, in which the B.sub.12 is labelled (in preferred embodiments the B.sub.12 is labelled differently than the B.sub.12 in the IF-B.sub.12 complex); and (3) means for preventing R protein in the gastric juices from removing B.sub.12 from the IF-B.sub.12 complex, (in preferred embodiments such means are B.sub.

  • Patent number: 4263921
    Abstract: A surgical appliance in the form of a temperature sensing endotracheal tube includes any suitable type of endotracheal tube with a temperature sensor in the form of a thermistor mounted on the distal end portion of the tube for engaging the patient's trachea. Suitable wiring is connected with the thermistor and extends through the endotracheal tube side wall to approximately the midpoint of the tube with the free end of the wiring having a suitable connector for attachment to an indicating and/or temperature recording unit. If the distal end portion of the endotracheal tube is provided with a typical inflatable cuff, the thermistor is preferably mounted on the tube proximate the end of the cuff remote from the free end of the distal end portion. The portion of the outer face of the tube which extends across the thermistor preferably protrudes slightly from the adjacent portion of the outer face, to provide better contact with the trachea.

  • Patent number: 4261544
    Abstract: This is a universal, re-usable system to accurately locate and temporarily hold an element to-be-embedded in concrete in a form. The system includes at least two rails and at least one element locating plate. The plate is capable of being attached in combination with and supported by the rails at any point along their length, while the rails supporting the plate are capable of being located at any position on a concrete form, so that an element locating plate and the related work element are capable of being accurately positioned at any location within the form. In preferred embodiments the to-be-located element is an anchor bolt and the plate defines at least one opening of a size which allows the bolt to be inserted through the plate.

  • Patent number: 4258204
    Abstract: Acrylate ester monomers are produced in high yield and without polymerization by reacting an .alpha.,.beta.-unsaturated organic acid halide and a hydroxyl containing organic compound in the presence of molecular sieves. In the absence of molecular sieves the same reactants produce the monomer ester products in low yield and/or form polymers.

  • Patent number: 4163577
    Abstract: A removable and foldable camper module as provided which converts a utility vehicle, such as a van, into a recreational vehicle. The camper module includes kitchen cabinets and storage area with bench type seats attached to the opposite side of the kitchen area. When the module is collapsed, it can be easily removed from the van by two people. In the expanded mode, the module provides the necessary fixtures that one would have in a recreational vehicle, but still allows mobility by the person using it. For storage and handling, the camper module folds in the center forming a compact rectangular package.

  • Patent number: 4043582
    Abstract: A restraint device for protecting young children in the sleeping compartments or bunks of a recreational vehicle includes a net-like device, constructed of flexible strands in close proximity of each other, that is supported within and attached to the upper bunk so as to provide simultaneous vertical and horizontal support. This net-like curtain arrangement transmits a portion of any horizontal force received by the device causing the lower fastening apparatus to become more securely fastened. Quick release snaps are provided in the net-like curtain device to allow an adult ready access to the infant in the bunk. The quick release mechanism is such that an adult may have ready egress from the bunk, but a young child cannot release the mechanism. The net-like curtain device slides to the side, out of the way when the bunk is not in use.

  • Patent number: 4004766
    Abstract: A vibration absorbing transmission tube isolation clamp which effectuates reduction of transmittance upon structures in communication with a tube being held by the clamp of side to side forces generated by thermal expansion of the tube as the tube transmits liquid under pressure. The clamp comprises a bottom piece securable to a support structure and a top piece securable to the bottom piece with the tube positioned between the two pieces which are shaped so that when secured together a tube housing results which totally surrounds the tube for the length of the clamp. The base of the bottom piece is provided with two or more elongated openings whose long axes are at right angles to and lateral to the longitudinal axis of the tube housing.
