  • Patent number: 5617777
    Abstract: An automated deep fat frying apparatus comprises a plurality of cooking vats in a housing having a filter pan pump assembly. The apparatus has an oil distribution system and a control system having a computer programmed to operate and control oil transfer functions. Motor operated drain and return valves with position sensors are installed on each vat in the oil distribution system and operated by the control system to provide an automatic filter function and an oil transfer function whereby oil is drained from a first vat and transferred to a second vat according to selection inputs from the operator. The system includes operator selectable automated fill and dispose functions. In addition to valve position sensors, the system includes oil level sensors in the vats and filter pan, a pan position sensor and may include level sensors in a supply or dispose tank tied in to the control system which prevent mishaps during oil transfer operations.

  • Patent number: 5612198
    Abstract: Insulin-like growth factor-1 (IGF-1), a naturally occurring, relatively short, single chain polypeptide, is prepared by growing methylotrophic yeast transformants containing in their genome at least one copy of DNA encoding IGF-1, in operational linkage with DNA encoding a signal sequence, which is effective for directing secretion of proteins from the host cells and which also includes the proteolytic processing site lys-arg and may include one or more glu-ala sequences. In preferred embodiments the signal sequence is the S. cerevisiae alpha mating factor pre-pro sequence. Expression of both the DNA encoding IGF-1 and the pre-pro signal sequence is regulated by a promoter region derived from a methanol responsive gene of a methylotrophic yeast. DNA constructs and recombinant methylotrophic yeast strains used for the expression and secretion of IGF-1 are also provided. For preferred embodiments, protease deficient Pichia pastoris strains are provided.

  • Patent number: 5605668
    Abstract: A process for the preparation and purification of a cobalt oxide hydroxide intermediate from a cobalt sulphate solution containing cationic and anionic impurities, including the successive steps of (i) contacting the cobalt sulphate solution with an organic reagent to extract iron and zinc cationic impurities from the sulphate solution; (ii) extracting the cobalt from the sulphate solution with an organic reagent to produce a cobalt loaded organic phase substantially free of all anionic impurities; (iii) stripping the cobalt loaded organic phase with a concentrated ammoniacal ammonium carbonate solution to produce an ammoniacal ammonium carbonate strip liquor rich in cobalt II ammines; (iv) oxidizing the cobalt II ammines in the ammoniacal ammonium carbonate strip liquor to cobalt III tetraammines; (v) extracting the majority of nickel impurity from the cobalt III tetraammine rich ammoniacal liquor with an organic reagent; and (vi) recovering the cobalt from the cobalt III tetraammine rich ammoniacal liquor.

  • Patent number: 5597973
    Abstract: A signal transmission fuse (10, 20) such as shock tube has an outside diameter (OD) not greater than about 2.380 mm (0.0937 inch), for example, a tube outside diameter (OD) of from about 0.397 to 2.380 mm (about 0.0156 to 0.0937 inch), and the ratio of the inside diameter (ID) of the tube to the radial thickness of the tube wall (T) is from about 0.18 to 2.5. The inside diameter (ID) of the tube may be from about 0.198 to 1.321 mm (about 0.0078 to 0.0520 inch). The powder surface density of the reactive material contained within the bore (16, 30) of the fuse (10, 20) may, but need not, be significantly less than that which the prior art considers to be a minimum acceptable powder surface density.

  • Patent number: 5537011
    Abstract: An invention is disclosed which promotes even wear within a multiple-motor drivetrain. In one embodiment of the invention, a vehicle drivetrain includes two motors. The total torque to be provided by the motors is partitioned between the motors such that the total efficiency of the drivetrain is maximum. Such partitioning usually involves providing more torque from one motor than from the other. The motor selected to provide the greater torque does so until a predetermined number of differential torque-hours are accumulated between the two motors. The other motor is then selected to provide the greater torque, again until a predetermined number of differential torque-hours are accumulated. Excessive wear of one portion of the driveline is thus prevented.

  • Patent number: 5537436
    Abstract: A number of arrangements and methods that achieve concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than half the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components.

  • Patent number: 5536579
    Abstract: A multi-layer electronic circuit package including at least one electrically conductive plane, a first organic polymeric dielectric material having a first optical absorbency to an ablating wavelength of laser light, and a second organic polymeric dielectric material having a second optical absorbency to the ablating wavelength of laser light. The first material dielectric material absorbs wavelengths of light that are not the same as wavelengths of light that are absorbed by the second dielectric material. A first layer of the first or the second organic polymeric materials overlays at least one surface of the at least one electrically conductive plane and a second layer of the other of the first and second organic polymeric materials overlays the first layer.

  • Patent number: 5532671
    Abstract: The accelerator command signal from an accelerator pedal sensor of an electric vehicle is mapped to a generally lower value in view of a reduced state of charge of the traction battery of the vehicle. The mapping requires the driver of the vehicle to depress the accelerator pedal farther to provide an equivalent accelerator command to the controller which controls the traction motor of the vehicle. The driver is thus given intuitive indication that the powertrain of his vehicle has reduced propulsive capability.
