Title: Valved air vent used in tire vulcanization mold is made of only two parts, gripping into bore in mold and sealing at internal surface when green tire contacts domed resilient disc, in simple trouble-free design
Inventor: NITSCH BORIS
IPC: B29C33/10
Filed: 1998-07-27
Abstract: Each valve (1) is two-part, with central peg-like body fixed in mold vent bore, and complementing a detachable sealing section (3). This has a resilient flat area (4) laid against the interior of the mold. On contact with the surface of the tire blank, this works with the central body to form a seal.  Preferred features: The cylindrical central body diameter is less than that of the vent bore. Grips (10) on the body or sealing section fasten into the bore, also forming vent channels. The seal has a disc- or dome-shaped sealing surface with incisions (6) and/or recesses (7). Around its circumference, couplings (5) with in-turned hooked-ends connect it to the central body. The sealing surface is supported on the body at its edges. Resilient deformation towards and against the body closes the air openings. There is a main vent opening (7) centrally in the seal, closing onto a complementary body rest, when the valve closes. Side couplings have a bayonet-like attachment mode.  A variant of the design is described based on similar principles.  Bore/peg interference fit is quantified. Seal diameter exceeds vent bore diameter. Spring sheet metal may be used to make the disc seal, its thickness 0.05-0.5 mm. The dome characteristic angle is about 20 deg .

Title: Anti-locking control procedure for cars
Inventor: USUKURA KAZUHIRO
IPC: B60T8/64
Filed: 1998-11-20
Abstract: An anti-locking control procedure for cars is described which is executed when a car travels on a road surface with different friction coefficients, where one of the wheels on an axle rolls with a high coefficient and the other with a lower coefficient. Anti-locking control begins when  the brake is operated, the wheel on the road surface with the lower coefficient has an excessive slip in a first cycle of the anti-lock control, and a specified condition is fulfilled.  The procedure has the following steps: (1) progressive reduction of hydraulic brake pressure for the wheel on the road surface with the higher friction coefficient in each period, while the time interval for enforced pressure reduction is changed; and (2) after the pressure reduction with the presence of a further specified condition, the start of gradual reduction of the hydraulic brake pressure for the wheel on the road surface with the higher friction coefficient. This allows effective use of the surface and insufficient retardation of the car is eliminated.
