  • Patent number: 4819541
    Abstract: The drive is controlled such that reduced pressure is applied during a forward motion phase and venting flow from the drive is used as dynamic control pressure to hold off application of full driving pressure until, through physical impediment, piston movement stops. This way rebounding is prevented and strong holding pressure (e.g. on welding electrodes) is made available after a low power motion phase.

  • Patent number: 4820190
    Abstract: An electrical component mounting and connection assembly for direct connection to a connecting wire cable includes a base member having a cavity and wire-receiving slots into which the electrical leads of a sensor, such as a magnetically actuated reed switch, and the wires of the connecting cable are positioned. A cooperating insert member includes insulation displacing contacts and latching structures to physically latch the insert member and base member together to allow the insulation displacing contacts to establish electrical contact with the slot-retained wire conductors. The circuit wires follow a path to an exterior surface of the assembly to allow direct electrical probing of the wire ends to test the circuit components and their connections. In the preferred embodiment, the base member and insert define cooperating `snap` together parts that allow time and cost efficient connection of the sensor device assemblies at the point of installation.

  • Patent number: H621
    Abstract: A method of modifying the flavor of distilled spirits is provided. Crystalline fructose (optionally with crystalline dextrose) or aqueous solutions thereof are added to distilled spirits in minor amounts, e.g. less than 5% by weight, to modify the flavor thereof. The method is particularly applicable to distilled spirits containing natural flavor components, i.e. congeners, from distillation or maturation of the spirit. The addition of minor amounts of fructose serves to improve the palatability of the distilled spirit without overtly sweetening or undesirably masking the original flavor.
