Title: Filler or pigment prepn. - by hydrothermally reacting calcium oxide and excess silicic acid, comminuting and sepg. coarse and fine fractions
IPC: D21H17/68
Filed: 1982-11-18
Abstract: Fillers or pigments are prepd. by the hydrothermal reaction of a mixt. of CaO and silicic acid under increased pressure in several consecutive steps. In a 1st step, the mixt. is prepd. with silicic acid excess and the reaction prod. is comminuted after each step. Novelty comprises sepg. the comminuted 1st step reaction prod. into a coarse- and a fine fraction. The reaction prod. coarse fraction is then used again to prepare a mixt. of CaO and excess silicic acid. This mixt. is treated hydrothermally in one or more further steps, comminuted and sepd. The prods. can be used as additives in rubber, paper, plastics, ceramics, paints and lacquers; as thickeners in cosmetics, e.g. in moisturising creams or tooth-pastes, and as carriers for tensides and artificial fertilisers. The fillers and pigments have large surface and high reinforcing activity and are prepd. by an energy consumption-saving process.

Title: Ignition distributor for IC engine
Inventor: INOUE TAKUMI
IPC: F02P5/10
Filed: 1983-07-12
Abstract: The distributor has a rotating shaft coupled to the crankshaft with a cam mounted on the shaft and acting on a contact breaker switch to interrupt the current in the primary winding of the ignition coil. An ignition advance controller adjusts the advance angle with changes in the crankshaft speed. A driver is fixed to the distributor shaft and motion is transferred to breaker points carrier through a magnetic or fluid coupling which transmits the motion with a predetermined amount of slip between the driving and driven parts. The motion of the breaker points carrier plate alters the crankshaft angle at which the distributor cam becomes effective.
