  • Patent number: 11976255
    Abstract: The invention relates to solidification of liquid amine oxide, betaine, and/or sultaine surfactants with a binder to form a solidified surfactant composition. In particular, the invention relates to solidification of liquid surfactants utilizing drying device(s), wherein the feed composition contains at least one liquid surfactant and a binder and optional carrier to form a solidified surfactant composition. The solidified surfactant compositions can be useful in various cleaning compositions.

  • Patent number: 6775960
    Abstract: The present invention concerns a device, an arrangement and a method for opening or separating two closely joined sheets of flexible material, e.g. sheet pieces and folded pieces of film or paper, by applying vacuum on the opposite outer sides of these joined sheets. Typically, the case is opening different packing wrappers or large bags or envelopes, which are to be opened for receiving inserts, e.g. diverse advertisement prints, and which are to be handled with great reliability and rather large capacity, e.g. 5,000 to 25,000 pcs. per hour.

  • Patent number: 6437460
    Abstract: A low power supervisor controller for an electric vehicle substantially reduces ignition-off draw current in the main control module. The supervisor controller has a sleep controller for powering down the main control module when an interrupt event has not occurred. The sleep controller powers up the main control module when the interrupt event has occurred. The supervisor controller also has an interrupt monitor for determining when the interrupt event occurs, as well as a supervisor wait module. The supervisor wait module establishes and controls an interrupt cycle, wherein the interrupt cycle is defined by an amount of time between determinations of the interrupt monitor.

  • Patent number: 6175303
    Abstract: The present invention provides a system for monitoring usage of a electric vehicle's battery which offsets the display when the vehicle is in an on condition. A battery energy measuring device is provided which measures the conditions indicative of the maximum available current of the battery and generates a charge signal indicative of the conditions indicative of the maximum available current of the battery. A display is provided which is responsive to the charge signal for displaying the maximum available current of the battery. An offset device is provided which is responsive to the keyswitch to provide a keyswitch signal to the battery energy measuring device representative of the on and off condition of the keyswitch. The battery energy measuring device offsets the charge signal when the keyswitch is in an on condition such that the display displays the on and off condition of the keyswitch.

  • Patent number: 6008652
    Abstract: A battery tub tester is disclosed that tests the individual batteries, battery accessories and connections as they are being assembled into a battery tub for an electric vehicle. The batteries and battery tub accessories, including temperature sensing devices and battery monitor modules, are mounted and electrically connected in the battery tub in accordance with a known battery tub assembly scheme. As the assembler mounts and connects the batteries and battery tub accessories, the tub tester determines the battery voltages of each battery after it is mounted and connected within the tub to determine if the batteries have the desirable voltage and will operate as they are intended and are connected properly. Additionally, the tester determines the temperature readings as the temperature sensors are being mounted, to determine if the temperature sensors will operate as intended and are connected properly.
