  • Publication number: 20230208251
    Abstract: An electric motor contains a motor shaft which is arranged in a motor housing. The motor shaft is rotatably mounted about a rotational axis in at least one rolling or ball bearing, which sits in a bearing receiving area and contains an outer ring and an inner ring fixed to the motor shaft. The outer ring of the rolling bearing is pretensioned by a spring disc which sits in the bearing receiving area and has a number of wave trains with alternatingly axially projecting half wave trains, and the spring disc has a number of centering elements on the inner circumference. The centering elements rest against the motor shaft when the spring disc is untensioned and is arranged at a distance to the motor shaft when the spring disc is tensioned.

    Abstract: A method for depositing a CdTe layer on a substrate in a vacuum chamber by means of physical gas phase deposition is provided. The substrate is heated to a coating temperature before the deposition process and then guided past a vessel in which CdTe is converted into a vapour state, a gaseous component with an increased pressure (compared to the vacuum in the vacuum chamber) flowing through at least one inlet, against the substrate surface to be coated, such that the gaseous component is adsorbed on the substrate surface to be coated before the substrate is guided past the at least one vessel.

  • Patent number: 7056653
    Abstract: The extent of binding of a moiety, such as a biomolecule, to a surface, where the local environment at the surface has a pH or surface potential which is altered upon binding of the moiety, is determined by stably incorporating at the surface a probe which contains a pH- or potential-sensitive fluorophore.

  • Patent number: 6411911
    Abstract: A method for monitoring and diagnosing the status of a battery in an electrical system, more particularly, a method for determining a battery's reserve time based on comparison of measurements made during a battery discharge to a universal normalized discharge curve. Specifically, a battery discharge is initiated and the battery's voltage and discharge time is continuously measured. The measured battery voltage is normalized by dividing it by either the peak voltage or foothill voltage, as monitored during the discharge. By comparing this normalized voltage measurement to a universal normalized discharge curve, the percent discharge level of the battery is determined. Using the percent discharge level and the discharge time, the reserve time and total capacity of the battery can be determined.

  • Patent number: 6137292
    Abstract: A battery diagnostic method for monitoring the status of a battery in an electrical system and continuously providing a relatively accurate prediction of battery condition and performance, more particularly, a self-adjusting method for providing the best possible prediction of a battery's reserve time before, during, and after a battery discharge. The method of the present invention utilizes different prediction methods depending on what state the electrical system is in; that is, before, during or after a battery discharge. By determining what state the system is in, the most effective prediction method can be utilized to provide an accurate battery reserve time. By providing a relatively accurate continuous reserve time prediction, the method helps prevent a complete loss of power in an electrical system relying on a battery to supply the system's electrical power.

  • Patent number: 5746775
    Abstract: A method of treating a collagenous biomaterial, such as porcine aortic valve leaflets or bovine pericardium, by exposing the biomaterial to an alcohol to inhibit in vivo calcification. The biomaterial, preferably glutaraldehyde-pretreated, is subjected to an aqueous solution of 60% to 80% lower aliphatic alcohol, such as ethanol for a period of at least 20 minutes, and preferably, 24 to 72 hours. The biomaterial is rinsed, and then stored in either a glutaraldehyde-free environment or an ethanolic solution of glutaraldehyde. In some embodiments, the treatment solutions include an additional anticalcification agent which may be a soluble salt of a metallic cation, such as Al.sup.+3 or Fe.sup.+3.
