Abstract: The present invention discloses an open gas fire having a gas burner, the combustion products of which are fed to a flue system via a heat exchanger for use in providing heated convection air. In the invention an adjustable baffle is arranged to vary the flow-through cross-section of the path of the combustion products to the flue system, thus matching the flue cross-section to the combustion products quantity, thereby reducing the quantity of cold air drawn into the front of the fire and improving thermal efficiency of the gas fire apparatus.

Abstract: Lower aliphatic dialdehydes have been found to react with human and other animal tissues in the living animal and that treatment of exposed tissue by topical application is useful in converting "wet" gangrene to "dry" gangrene, in forming a protective eschar for burned tissue, and for treating the raw, cut portions of the body during surgical excision of malignant tumors to prevent growth of implants resulting from dissemination of malignant cells during the excision. Threatment is generally by topical application of the dialdehyde diluted, typically, to 1 or 2 percent in a fluent carrier such as water or alcohol.

Abstract: A low-power personal epilepsy seizure warning system is disclosed based on the clinical observation that while the brain potentials marking the onset of epilepsy vary from patient to patient, indicative brain potentials in any one patient are highly likely to remain constant. The system includes an implantable monitor to detect brain potentials and recognize the onset of a seizure, and an external warning unit to warn the patient when a seizure is imminent. The monitor is configured to recognize a patient's indicative potentials after preoperative EEG observation, and may include relatively simple analog circuitry to recognize simple forms, or a microprocessor and programmed memory to recognize complex forms utilizing algorithms such as the fast Fourier transform. An external program adjustment unit may also be utilized to increase or decrease the sensitivity of the monitor corresponding to the patient's experience of insufficient or excessive warnings after implantation.

Abstract: A remote manipulator arm for positioning and operating tube sheet repair tools within a nuclear generator shell. The arm includes a number of arm segments linked serially, each having a remotely-controlled motor to pivot an elbow in the arm segment by way of gears. A mounting bracket passes through a manhole in the generator shell and provides a stable point of connection for the arm, both inside and outside the shell, as well as connections for power and control signals to the arm. A workhead is provided for mounting on the arm end opposite the bracket, and can carry a plurality of tools to conduct repair operations on tubes. The mounting bracket can be installed from without the shell and does not block the manhole, and the arm is self-installing, requiring no human presence within the generator shell.

Abstract: A stretch wrapping apparatus and process for wrapping and sealing random-sized loads, in which the load is surrounded with a plurality of tube forming support members which extend along the length of the load. A conveyor directly beneath the load supports the load and preferably incorporates at least one upper and one lower endless belt, rotating so that the upper surface of the upper belt and the lower surface of the lower belt are both carried in the same downstream direction at the same speed. The tube forming support members converge to the load with skids which do not support the load, and preferably have endless conveyor belts with an outer surface circulating in the same downstream direction and at the same speed as the lower dual conveyor. A stretched film web is wrapped around the tube forming support members, conveyor, and load by a film dispenser, wrapping the load as well as space in front of and behind the load.

Abstract: A method for conversion of digital computer source code software to operate in a system foreign to that from which the software originated. A library is created in which each entry incorporates the name of a code statement, or macro, which may require conversion and expanded code statements which may be selected to replace the macro. Each expanded code statement may be accompanied by one or more parametric triplets, each of which corresponds to a parameter within the expanded code and expresses a condition under which the expanded code is bypassed depending on the presence or absence of the parameter in any source code statement containing the macro. The source code statements are examined serially and any statement containing no macro entered in the library is passed to an output file, while any macro is replaced by any expanded code from the dictionary for which no bypass condition is satisfied.

Abstract: The invention comprises a novel apparatus for making unitary completely wrapped packages. In the apparatus, a series of loads are fed into a wrapping apparatus onto a wrapping conveyor assembly comprised of a plurality of conveyors. The film is continuously wrapped around the load and the conveyor assembly to form a spiral bundle with the load being carried off by the top portion of one conveyor and the wrap being carried off the bottom portion of another conveyor so that the load and wrap are carried off at the same speed onto a take-off conveyor. The spiral stretched film web is sealed and severed between adjacent loads by a cutting and sealing apparatus to form a six sided compressive wrap around each load.

Abstract: A wrapping apparatus having a rotating ring which carries a film dispenser carriage adapted to dispense film web around a load carried on a wrapping conveyor. A traveling film clamp mechanism is mounted adjacent the wrapping conveyor and extends through the plane of the rotating ring to engage, clamp, cut and brush film web dispensed from the film dispenser carriage. The traveling film clamp mechanism incorporates a linear driver assembly, a fixed clamp jaw mounted to the linear driver assembly and positioned substantially parallel to the line of travel in which the linear driver operates, a rotating jaw mounted to the linear driver assembly adapted to close against the fixed jaw to clamp film web therebetween, and a rotating cutter brush arm carrying a leading cutter edge and a trailing brush.

Abstract: A holder for a toothbrush is provided which includes a first substantially rectangular side wall, a second substantially rectangular side wall sharing a first common longitudinal edge with the first side wall and angulated thereto, said second side wall being wider than said first side wall and a third substantially rectangular side wall sharing a second common longitudinal edge with said second side wall, and extending substantially normal thereto. The first and second side walls define therebetween a wedge-shaped chamber adapted to receive the bristles of a toothbrush and to bias the sides of the bristles inwardly while said third side wall defines retaining means for retaining the toothbrush in the holder. The bristles, upon insertion into the holder form a wedge-shaped mass whereby they retain their natural operative direction without deformation during drying thereof.

Abstract: The present inventive apparatus measures the output of urine optically, totalizes it and prints it on a self-adherent paper which can easily be afixed to the hospital chart. The apparatus includes a measurement column, an optical sensor to determine when the measurement column is empty, a peristaltic pump to empty the measurement column at a known rate, into a collection bag or specimen bottle and control logic to determine the volume removed from the column based on the pump rate. A display is also provided for easy observation of current output statistics. Specimens can be collected under automatic or manual control for biochemical analysis without contamination by contact or alteration by electrical current. An alarm may be sounded when the collection bag is in need of replacement, or when the urine output falls or rises to predetermined rates.

Abstract: The method of treating tumors by radio frequency heating at the location of the tumor to cause necrosis of the tumor tissue in which hypotension is induced during the treatment.

Abstract: A method of treating tumors, both benign and malignant, such as carcinoma, sarcoma, cysts and avascular lesions, in animals, such as humans, by radio frequency heating at the location of the tumor in the host with intensity and duration sufficient to cause necrosis of the tumor tissue. Substantial damage to the surrounding normal tissue is avoided, as the surrounding normal tissue is cooled by blood flow which carries the heat away to dissipate such heat in those portions of the body not being subjected to heating.
