  • Patent number: 5831843
    Abstract: A device for converting direct voltage into a three phase alternating voltage having a two level converter connected to a direct voltage network and to an alternating voltage network. A control apparatus for performing pulse width modulation determines the pulse width modulation pattern for each phase by comparing a triangular wave for each phase with a reference alternating voltage. The triangular wave is inverted an even number of times during a fundamental oscillation of the reference alternating voltage and the time position of the inversions of each triangular wave is always such that two triangular waves are half a period displaced with respect to the third.

  • Patent number: 5446897
    Abstract: A method and apparatus for automatically associating physical network addresses with logical identifiers in local area networks. The physical network address is transmitted to a central administrator of the local area network, where the association between such address and a logical identifier is made. In the case where a new device is being installed on the network, the logical identifier may be an arbitrary word, number, or combination thereof which is supplied by the operator at the central administrator. In the situation where a device is being replaced, the logical identifier is the same as the identifier of the replaced device, while the physical network address of the replacement device is substituted in the association for the address of the replaced device. A compilation of the associations is maintained at the central administrator, and the associations are transmitted back to the devices being installed or replaced, as well as other devices on the network.

  • Patent number: 4902458
    Abstract: A method of molding generally hollow components and assemblies for a bicycle frame of composite materials, such as heat curable synthetic resins reinforced with structural fibers. The entire bicycle frame may be one integrally united piece. Layers of the composite material are shaped to form a shell for the frame component.

  • Patent number: 4893257
    Abstract: A character generator with multidirectional scan and variable line and character (or symbol) size capability is disclosed. Universality is implemented by producing a serial binary stream which can be used to print or display in any of eight combinations of scan direction and progression, that is, for scan direction left to right, or vice versa, progressing up or down, or scan direction top or bottom or vice versa, progressing left or right. In formatting the serial binary stream, a font is accessed (for basic symbol definition), which selectively provides for orthogonal scan of the symbol definitions. Variable line size is implemented by terminating a symbol row (or line) based on a predetermined size criteria regardless of the comparable font dimension and "filling" up to the line size to the extent the corresponding font dimension is less than the predetermined size criteria.

  • Patent number: 4831521
    Abstract: A method and apparatus for effecting vital functions notwithstanding the fact that non-vital hardware is employed. A vital processor is implemented using non-vital hardware in the form of a digital computer which may for example be a microprocessor. The vital processor accepts binary input values and, based on a series of logical expressions relating output values to input values, determines the appropriate output values. Rather than employing a single bit to represent the condition of a particular input or output, unique multibit binary values or names are used. Each input or output has assigned to it at least two unique multibit values, each satisfying the code rules of a different code. Thus rather than representing a closed contact as a single 1 bit, and an open contact as a single 0 bit, the closed contact is represented by a unique multibit name which satisfies the code rules of a first code.

  • Patent number: 4679498
    Abstract: Apparatus for preparing a chocolate paste in which the various ingredients comprising at least cocoa and powdered sugar are subject to operations of grinding to a predetermined degree of particle size, of fluidification by dispersion of the particles of sugar and of cocoa into a continuous fatty phase and of degasification for the removal of water and undesirable volatile compounds. At least part of the treatment is carried out in a conveyor with several screws and an arrangement for regulating the temperature of the entrained material. After preliminary grinding of the ingredients to obtain a refined paste having the desired degree of particle size in the screw conveyor, dry-conching of the refined paste is carried out and then the liquefaction of the paste is obtained by the incorporation of additives in accordance with the receipe.

  • Patent number: 4650625
    Abstract: The invention relates to a method for forming an article by injection molding, such as a shoe, and comprises the formation of a mold (5) by coating a master pattern of the article with a pourable, heat-resistant molding compound, such as an epoxy resin or polyurethane. The master mold (5) so formed is secured in a mold casing (1) for an injection molding plant and molding material such as poly-vinyl chloride or polyurethane is injected to form the finished article. The master mold may be formed directly in the mold casing (1) to which it can be secured such as by mechanical securing and located means (6,7,8,) or by being adhered thereto. In an alternative embodiment of the invention, the master mold may be formed in a mold box and subsequently fitted into the mold casing (1) for reproduction of the article.

  • Patent number: 4481886
    Abstract: This invention relates to a hollow charge for a missile, projectile, shell or the like. The invention is particularly intended to be used on a missile which is arranged to pass a target and the hollow charge initiated when the missile is over, at the side of or under the target which means that the hollow charge is inclined with respect to the longitudinal axis (13) of the missile. The hollow charge comprises an inner, jet-forming, trumpet-shaped cone member (3) and an outer casing (2) having a substantially straight cylindrical part (8) connected to a conical tapered part (9, 10) to give the hollow charge jet an extremely high front tip velocity as well as a low velocity gradient.

  • Patent number: 4013244
    Abstract: Apparatus for controlling the output power of a laser diode the beam of which is directed in a selected direction toward a target so as to enable a missile or the like to be directed along the beam toward the target. The apparatus includes a circuit which supplies a variable amount of power to the diode, and a circuit which is responsive to the radiation emitted by the diode, and the latter circuit generates a signal which is proportional to the magnitude of the emitted radiation. A control circuit is provided which is initiated into operation at the time of firing of the missile and generates a signal which represents the desired increase in magnitude of the radiation emitted by the diode during the time of travel of the missile toward the target.

  • Patent number: 3940558
    Abstract: A clock for locally distributing a synchronized signal derived from a remotely transmitted signal. The clock normally operates in the slave mode, phase locked to the remotely transmitted signal, when that signal is deemed available. If it is not available the clock switches to a master mode in which it independently generates the necessary signal.
