Title: Potential target for an immunotherapeutic approach to stop huntington's chorea in humans: cdna and protein structures for an intracellular activator of the human glutamate receptor, brain lactate dehydrogenase and vacuolar atpase reconstructed from the antisense strand of baboon urate oxi dase gene
Inventor: PREDDIE RICK E
IPC: C07K14/47
Filed: 1993-01-25
Abstract: ABSTRACT          Recently it has been shown that very high concentrations of lactic acid accumulate in the brains of people with Huntington's disease and that the neurons which die in the brains of these patients  are   virtually   overexcited  to  death  by  the neurotransmitter  glutamate.  There is no know cure for Huntington's chorea. A 216 base pair cDNA reconstructed from the antisense strand of baboon urate oxidase gene encodes a 64 amino acid, 7.6 kD, peripheral membrane associated protein which appears to be an intracellular activator of the glutamate receptor, brain lactate dehyrogenase and vacuolar ATPase. These three proteins acting together are capable of leading to the death of neurons and to deposits of high concentration of lactic acid observed in the brains of Huntington's disease victims. Although not yet identified, a similar protein is expected to be present in humans. Because the 7.6 kD protein is encoded by DNA homologous to the antisense strand of urate oxidase mRNA it cannot be expressed in the presence of a normal wild type urate oxidase gene, but mutations and/or deletions occurring in strategic regions of the gene can allow expressions of the protein.  Since this protein cannot be expressed in healthy humans, immunotherapeutic reagents directed against it should be useful for stopping Huntington's disease in humans without having any effect on other metabolic reactions.

Title: Tactical directional penlight
Inventor: FONSEKA DAVID M
IPC: F21S8/00
Filed: 1993-02-02
Abstract: ABSTRACT OF DISCLOSURE       The device is a penlight designed primarily for military personnel. By attaching the device to one's breast pocket or to a metal body with a pen-clip and a magnetic strip respectively, the bulb-head can be adjusted to direct the light to a desired object without having to hold the penlight, making it ideal for map reading. The hood of the bulb-head inhibits the projection of light in a horizontal direction where hostile forces may be watching. The invention comprises a plastic tube which holds two "AA" size batteries and where the top part houses a switch and an adjustable magnetic bulb-head.  A cap cover at the bottom of the tube houses five different coloured metal-rimmed filter discs which can be quickly attached to the magnetic bulb-head if coloured light is desired. The bulb-head can be adjusted up and down within a 150 degree angle and laterally within a 360 degree angle. A luminious tube secured to the  bulb-head converts the penlight into a traffic wand. The device is water-resistant and has its uses also for civilian applications.

Title: Imaging method for defining the structure of objects
Inventor: PUUMALAINEN PERTTI
IPC: G01N23/04
Filed: 1991-10-02
Abstract: The invention relates to an imaging method for defining the structure of objects. Current methods and apparatuses are complicated and expensive, and cannot be applied to purposes where a large amount of images is needed in a rapid succession. In the method of the invention, the object (13) under inspection and at least one radiation source (11) and at least one detector (12) are moved in relation to each other, so that the object under inspection passes through the radiation transmitted by the radiation source, and at least one detector is used for measuring the changes in the intensities of radiation absorbed, at least partly, in the object under inspection, as a function of the motion of the said object.  Thus, the structural points needed for imaging the structure are defined from at least two directions, and as the passage of radiation in the object at the moment of measurement is always known, the three-dimensional structure of the object is calcutated.

Abstract: An electronic inductive switching power amplifier designed for but not limited to amplification of electrical audio signals consists of a power conversion system, a signal control system together with a direct current power source wherein the power conversion system comprising of a pulse width modulator circuit, primary semiconductor switches and a high frequency switching transformer wherein the direct current power source is pulse width modulated through primary winding on the switching transformer by the primary semiconductor switches being controlled by the pulse width modulator. The switching transformer further comprises of a secondary winding wherein the primary to secondary winding ratio effects the required power conversion and amplification. The Direct current power source can be but not limited to 12 or 24 volts direct current (DC) from automobiles or DC derived from rectified and filtered 115 volts Alternating current (AC) main supply. The signal control system comprising of a multifunction preamplifier, an output driver circuit, a full wave rectifier, output semiconductor switches and a low pass electronic filter wherein the electrical audio input signal to be amplified is applied to the multifunction preamplifier thereafter producing two output signals one being an absolute value signal controlling the pulse width modulator and the second signal which is a square wave switching signal at the same frequency and phase as the input signal controlling the output driver circuit thereby producing complimentary switching signals further controlling the output semiconductor switches. The pulse width modulated output signal from the secondary winding on the switching transformer passes through the full wave rectifier and thereafter being alternately switched through the low pass filter whereby the original input waveform is reconstructed but at a greatly increased power level. This output signal is connected to a power take off point such as electrical terminals where an electrical load or loudspeaker is connected for audio reproduction.
