Title: A high-voltage, noninductive, film-type resistor, and a method of making it
Inventor: CADDOCK RICHARD E
IPC: H01C7/22
Filed: 1985-11-06
Granted: 1988-06-30
Abstract: A method of making a high-voltage, noninductive, film-type resistor comprises forming on an insulating substrate (10) a coating of resistive material and then using a laser beam to cut through and selectively remove portions of the coating so that the remaining coating forms a zigzag line <11). The zigzag line (11) is formed so its adjacent portions converge towards one another at an angle sufficiently small that, in use, there is a major inductance-cancellation effect between currents flowing in adjacent portions. Preferably, the laser beam removes the coating from a series of adjacent parallel regions (12, 13, ... 17) to expose a portion of substrate (10) beneath each region, the adjacent regions having substantially different lengths. The resulting resistor is extremely compact, stable and has a precise value.

Abstract: PCT No. PCT/SE85/00128 Sec. 371 Date Nov. 18, 1985 Sec. 102(e) Date Nov. 18, 1985 PCT Filed Mar. 21, 1985 PCT Pub. No. WO85/04254 PCT Pub. Date Sep. 26, 1985.According to the invention a piezoelectric crystal, e.g. a quartz crystal, coated with a metal or another suitable material is exposed to the action of a corrosive liquid, preferably by being immersed therein. The mass change on the crystal surface, caused by the corrosion, and the resulting change in the natural oscillation frequency of the crystal is determined and constitutes a measure of the corrosivity of the liquid. The natural oscillation frequency of the crystal can in this way also be measured in situ in the liquid, in which way the dynamic course of the corrosion reaction can be followed continuously. According to a special embodiment of the invention the sensitivity during the measurement can be increased, if the crystal is pretreated by being activated with a sulphide solution.

Abstract: The motor protection switch comprises a movable contact piece being manually movable by way of an actuator, which includes actuator buttons. The contact piece can be brought in and out of contact with a resting contact piece. The motor protection switch can also be released by overload current or short circuit current. A retracting or pullback mechanism with two settings settable from outside are provided for the actuator. In the first setting the pullback mechanism will hold the actuator in a trip position between the "on" and the "off" position after overload tripping or short circuit tripping has occurred. In the second setting the pullback mechanism will allow direct movement of the actuator from said "on" position into said "off" position after overload tripping or short circuit tripping has occurred. The simplest embodiment of the pullback mechanism includes a pullback spring acting on a rocking beam mounted between the actuating buttons, the housing side end of which spring is mounted on a slide having two settings. The two settings of the pullback mechanism allow to activate or to deactivate the trip position of the motor protection switch.

Abstract: Collagen membranes with desired properties are prepared by using a variety of gel-forming techniques in combination with methods for converting the gels to solid forms. One technique involves compressing a gel matrix under constant pressure to form a fibre network which is dried; another involves disrupting and centrifuging a matrix, harmonizing the precipitate auto or paste and casting and drying the paste. The properties of these membranes or other solid forms may be further altered by cross-linking the collagen preparation either after formation of the membrane or gel, or most preferably by mixing cross-linked collagen with solubilized collagen in the original mixture used to create the gel.

Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.

Abstract: The number of polarity changes in an incoming signal is periodically sampled for a defined time. Each incoming line (AL1,..ALn) is individually sampled. The polarity changes are counted and compared with the number of signal polarity changes to  be expected at the transmission rate at which the data system is operating. If this number if exceeded the affected line (AL1,..ALn) is switched out to eliminate disturbance to the data processing system (EDS). In the processing system (EDS) there are memories (LB,NB) in which the incoming line signals are stored as control signal (LB) and as data (NB) whose polarity count is to be checked. After decoding (DEC) the individual line polarity changes (Z1,..Zn) are compared with the norm and a signal (G) sent to the control unit (PE) if spurious additional changes are detected.

Abstract: The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56 DEG C in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.
