Patent SE-7513931-L (SE)
Inventor: BERG R D
IPC: H01G4/40
Filed: 1975-12-10
Abstract: A wound resistor-capacitor network having stable frequency response over a wide frequency range (e.g., 60 cycles to 100 kilohertz), is produced by forming a pair of aligned circumferentially extending resistance paths in one of two strips of metallized dielectric film. Forming of the resistance paths is accomplished as the two metallized strips are being wound to form an R-C network roll, by removing metal from the one strip along a first line to produce a gap in the metal layer in parallel spaced relationship to an adjacent edge of the film. Subsequently, removal of metal from the first strip also is initiated along a second line spaced inward from the first line, to produce another gap in the metal layer, thereby forming an elongated first path of desired resistance between the two lines. Metal removal along the first line then is temporarily interrupted to provide a lead termination area and a current steering path at the adjacent end of the network roll, on either side of the strip midpoint. Metal removal along a third line in alignment with the first line then is continued until an elongated second path of desired resistance has been formed between the second and third lines, at which time metal removal along the second line is terminated. Lines of metal also may be removed from the second dielectric film to provide a lead termination area and a current steering path at the opposite end of the wound network roll. Preferably, the metal is removed with the split beam of a single laser and the lines of removal are symmetrical on opposite sides of each strip's longitudinal midpoint.

Abstract: Testing of rheological properties of a fluid is performed between a pair of members having cooperating faces, each characterized by minute, randomly interspersed land portions and cavity portions. The land portions of each face are planar and are disposed geometrically in a common plane. The cavity portions are irregular and are disposed in a network subordinate to the common plane. Testing involves the steps of placing a sample of the fluid between the cooperating faces, pressing the cooperating faces into flush contact with each other, and pulling the cooperating faces from each other. The force required for rupture of the fluid within itself, without first breaking its contact with the cooperating faces, is a function of the shear stress, yield point and other rheological properties of the fluid.

Abstract: Apparatus for icing, freezing or frosting containers such as drinking glasses comprising a tank containing liquefied gas under pressure which is supplied through a valve and a coiled capillary conduit to a nozzle which sprays the liquefied gas into the interior of the drinking glass. A displaceable receiver plate is adapted for placement of the glass thereon and, in response to pressure applied to the glass, the receiver plate is displaced to open the valve which releases the liquefied gas from the tank into the coiled capillary conduit and, then, from the nozzle into the interior of the glass. The coil configuration of the capillary conduit provides resilience thereof and allows the same to undergo deformation as the receiver plate is displaced. The capillary conduit also serves to convey the liquefied gas along an elongated path to provide heat exchange with the ambient atmosphere, pressure reduction of the liquefied gas and a time lag so that, at discharge from the nozzle the liquefied gas is in an ideal liquid-gaseous state.

Abstract: A fuel injection pump having a mechanically adjustable servo valve for controlling the timing of the pumping event is disclosed. A pivoted lever has one end which engages the spring seat of a timing control plunger servo valve which is also subjected to a speed related hydraulic signal and another end which engages a cam clamped on the throttle shaft to pivot the lever according to the rotational position of the shaft. The profile of the cam is such as to retard the timing of the pumping stroke when the charge delivered by the pump is increased so that pressure built up in the pump is delayed and injection pressure is reached at a substantially constant crankshaft angle regardless of variations in speed and load on the engine. The mechanism is failsafe since it cannot interfere with the movement of the throttle shaft to reduce fuel delivery.

Abstract: Aqueous metal ammine siliconate solutions are the reaction products of selected metals or metal derivatives, selected mono-organosilicon materials, certain alkaline nitrogen compounds having the formula R-NH2, and water. Amorphous materials are formed when volatiles are removed from the siliconate solutions. The metal components in the resulting amorphous materials are not readily leached out by normal weathering, washing or the like. The solutions are useful in a method for treating substrates, such as wood, textiles, thread, canvas, carpeting, paper and masonry, to confer antimicrobial properties. The organosilicon component can be selected so that such treatments also confer either hydrophobic or hydrophilic properties to the substrates. The components of the solutions can be selected to enhance their ability to form continuous films of amorphous materials when used in such treatments, making the solutions useful to provide antimicrobial coatings which may be either hydrophobic or hydrophilic. Such amorphous coatings are useful for applications such as wood preservation, masonry water repellents, marine varnishes and as treating agents to give a desirable hand to fabrics. Powdered amorphous materials can be used to produce antimicrobial ointments. The solutions are useful as hardeners for water-reducible resins and emulsions, including latex paints. The solutions can also be adapted to include components which may be slowly leachable from the resulting amorphous materials which can thus serve as controlled-release binders to provide prolonged antimicrobial protection not only to the treated surfaces but also to their immediate surroundings.

Abstract: An external combustion engine is disclosed of the type including two or more circular rotors rotatably supported, one of the rotors acting as a power rotor and rotating in tangential contact with the other sealing rotor. The power rotor is formed with a radially projecting piston passing into a mating recess with the sealing rotor at a corresponding circumferential location. Steam or other working fluid is admitted via an intake port located opposite one face of the power rotor to cause rotation of the power rotor by expansion of the fluid in a working chamber defined by the space behind the piston. As the power rotor continues to rotate, the working chamber passes into communication with an exhaust port preparator to another power stroke. A vacuum relief port is provided at an intermediate location which relieves any vacuum condition which develops behind the piston during part throttle operating conditions of the engine. A pressure balancing groove is located on a face of the power rotor and pressurized with working fluid to balance the pressure acting on the power rotor by the location of the intake port on the opposite face of the power rotor. An absorber chamber is provided downstream of the throttle valve and upstream of the intake port to smooth out the pressure forces created by intermittent flow of fluid through the intake port. An elliptical port throttle valve design is disclosed which minimizes the wire drawing effect of the working fluid acting on the valve member during operation of the valve. A special rotor sealing surface treatment is disclosed comprising a series of slight depressions or holes formed in the mating faces of the power rotor and which generate a sealing due to condensation of the escaping steam in the surface indentations. Two and three rotor versions of the engine are described as well as one, two, and four power stroke per revolution embodiments.
