  • Patent number: 4406644
    Abstract: A torque transmission system has driving and driven pulley units around which an endless V-belt extends. Each pulley unit has a stationary pulley part rotatable with a shaft and a movable pulley part disposed to define with the stationary pulley part a circumferentially continuous groove for receiving the V-belt. The movable pulley parts of the pulley units are axially resiliently biased so that the radii of the circle along which the V-belt engages the driving and driven pulley units are varied to change the speed-change ratio of the transmission system. The movable pulley part of the driven pulley unit is axially shifted by the action of fly weights held between a stationary plate fixed to the shaft and a holder fixed to the movable pulley part.

  • Patent number: 4405911
    Abstract: An electromagnetic relay comprising a box-shaped relay case having an upper opening for accommodating therein an electromagnet, a group of resilient contacts and an operation card, and a relay cover for covering the case. The relay case and cover comprise insulated partition walls for separating the electromagnet from the group of resilient contacts. The partition walls are integrally formed with the relay case and the relay cover respectively, and overlap each other when the relay cover is engaged with the relay case. The use of the partition walls provides for an increased withstand voltage for the electromagnetic relay. In addition, the relay has a coil with grooved coil bobbins capable of receiving coil terminals in such a way that the electromagnetic relay may be mounted either in a direction parallel or perpendicular to the base of the relay case.

  • Patent number: 4102824
    Abstract: A dry cleaning composition comprising from 5 to 50 percent by weight of dialkyl (C.sub.2 to C.sub.4) alkanol (C.sub.2 or C.sub.3) amine salt of linear alkyl (C.sub.10 to C.sub.16) benzenesulfonic acid, from 30 to 60 percent by weight of other surfactant useful for dry cleaning and the balance is essentially an organic solvent for dry cleaning.

  • Patent number: 4097397
    Abstract: A detergent composition for dry cleaning comprising from 10 to 30 percent by weight of an alkanolamine salt of a linear alkylbenzenesulfonic acid having 10 to 14 carbon atoms in the alkyl group, from 30 to 50 percent by weight of a dialkyl ester of sulfosuccinic acid having 8 to 9 carbon atoms in the alkyl group, from 2 to 20 percent by weight of an adduct of 1 to 7 moles of an alkylene oxide to a higher fatty acid alkanolamide, and the balance is essentially an organic solvent effective for dry cleaning.
