Abstract: A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. The bowl is flushed and the contents are dumped into the filter cassette and the bowl is subsequently refilled. Filters in the cassette separate the coarse and fine particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Fine filtering and decoloring is accomplished by a carbon canister. A reservoir is provided for storage of fluid after removal of solid material therefrom in the cassette.

Abstract: A seat for use in a vehicle such as a motor car is disclosed in which a thigh support portion and a bottom support portion are integrally foamed with each other, and separate lower frame wires are embedded independently of each other within the respective support portions, whereby the thigh support portion can be smoothly moved up and down by a thigh support device provided therein.

Abstract: An improved vertical adjustment device for use with a seat in a vehicle such as an automobile is disclosed which is capable to adjust the cushioning function of such seat. In this vertical adjustment device, a cam with an operation lever is cooperatively connected with the sliding portions of a pair of X-shaped expansion legs by means of springs interposed between the cam and the sliding portions to energize the sliding portions in their sliding direction. The expansion legs are respectively provided between a seat support frame for carrying the seat thereon and a mounting frame to be fixed directly or indirectly to a floor of the vehicle. With this improved vertical adjustment device, the cam can be rotated to adjust the elastic forces of the springs.

Abstract: A fetal heartbeat signal detected by the principle of an ultrasonic Doppler effect is autocorrelated, and a fetal heart rate is detected from the periodicity of peaks of a determined autocorrelation function. In such a process, peaks of the autocorrelation function are detected, and a peak truly indicative of the fetal heart rate is detected from closeness of righthand inclindations of the peaks to a righthand inclination of the origin of the autocorrelation function.

Abstract: A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. Structure is provided for flushing the bowl and dumping the contents into the filter cassette and for subsequent refilling of the bowl. A filter is in the cassette for separating the particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Pumps and interconnected conduits are in the housing to transport fluid directly from an external source to fill the bowl after a flush, to transport and recirculate filtered fluid through the system for further waste disposal treatment, and to direct the effluent fluid from the system thereafter.

Abstract: A self-contained sewage waste disposal system is provided including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl is provided in the housing structure. A removable filter cassette is placed in the housing structure in communication with the toilet bowl. The bowl is adapted to be flushed to dump the contents into the filter cassette and to be subsequently refilled. The coarse and fine particles of solid waste material are separated from the fluid received from the bowl by filter material in the cassette. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette from the housing.

Abstract: A hydrophilic, flexible, open cell polyurethane-poly(N-vinyl lactam) interpolymer foam is obtained from the process which comprises reacting under interpolymer and foam-forming conditions (a) a substantially linear isocyanate-capped polyether polyol prepolymer having an average reactive functionality of less that about 2.0 with (b) a poly(N-vinyl lactam) and (c) a foam-forming amount of water in the presence of (d) a cell formation-regulating amount of surface active agent. The foams exhibit unexpectedly higher levels of absorptivity for aqueous fluids compared to those of known crosslinked foams. The foams herein are especially useful for the manufacture of a variety of dental and biomedical products including surgical bandages and dressings, laparotomy sponges, medicament carriers, and the like, where the capability for absorbing body fluids is an important performance criterion.

Abstract: The purpose of the present invention is to provide a physiological signal amplifier circuitry exhibiting higher common mode rejection ratio with no necessity of adjustment. To realize this, outputs of the differential amplifiers are average to produce reference potential which is supplied, through a high gain amplifier, to invert terminals of the same differential amplifier as well as to invert terminals of other differential amplifiers connected to other electrodes. In the embodiment employed for the electrocardiograph, the reference potential is produced by the differential amplifier connected to extremity electrodes, and other differential amplifiers are connected to the chest electrodes.

Abstract: A hydration system includes a refillable flexible liquid container or bag that is suspended from the shoulders much like a hiker's back pack with the weight of the liquid disposed on a centered position at the anatomic pivot point in the small of the back of the user. A trigger-actuated pump type liquid dispenser is attached to the bottom of the bag by a kink-free flexible coiled tube. The dispenser includes a nozzle that is adjustable between "stream" and "spray" positions, and has a hook and loop patch thereon which cooperates with a similar patch on a front strap of the suspension system for the ready attachment of the dispenser to the front strap of the suspension system and the removal of the dispenser therefrom. In a modification the walls of the container are insulated in order to maintain the temperature of the contents at a desired level.

Abstract: A respiratory gas concentration measuring apparatus includes a chopper having a first filter for passing therethrough light from a light source and having a first wavelength which can be absorbed by a gas to be measured and a second filter for passing therethrough light from the light source and having a second wavelength which cannot be absorbed by the gas. The chopper is rotatable to position the first and second filters alternately in a light path. The light having passed through the filters is converted by a photodetector into an electric signal. A first detector detects an output from the first filter based on the electric signal, and a second detector detects an output from the second filter based on the electric signal.

Abstract: An animal house is provided which is particularly adaptable for use with cats. The house is formed of an elongated base adapted to stand substantially vertical and a platform at the upper end of the base to form an animal perch. Access is permitted to the interior of the base for the animal to enter and leave the house. It is contemplated that the house can be formed of a unitary single piece of self-supporting material and in one form include an elongated substantially vertical base tapering inwardly from bottom to top and a substantially horizontal platform on the upper end of the base forming the animal's perch. The base is hollow with a hole provided for access to the interior of the house.
