PURPOSE:To make a differential gear case smaller by forming the lock mechanism from two clutching members having an engagement pawl, and by locating it in the place symmetrical to the case. CONSTITUTION:A lock mechanism 25 is composed of No.1 clutching member 26 of engagement type, which is fixed to the other end of a ring gear 20 with bolt, and No.2 clutching member 27, which is to advance and re...

PURPOSE:To provide perfect synchronized shifting for a power transmission at the time of speed-change by controlling gear ratios for a continuously variable transmission through a calculator by the use of detected values of every operation factor with respect to an automobile. CONSTITUTION:A power transmission 20, comprising a staged transmission 2, a continuously variable transmission 5, and a fl...

An automatic control circuit for a brake control device, relays around the device, light lamps and other parts to be operated differently under different circumstances, e.g., braking while running, braking to stop, releasing the brake pedal after braking, starting, parking after braking, and operation when the car stops in semi-automatic. The automatic control circuit operates a valve in the hydra...

An apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operati...

A foldable portable reclining chair composed of a soft material tent-type chair face and a stable chair frame body, wherein said stable chair frame body is composed of a plurality of support racks each in a proper length to be connected with a retractable joining device. Thus, when the user wants to fold and pack the chair up, he may draw the support racks along the pre-set direction away from the...

The invention relates to polyetherurethane particles having absorptive activity whereby these particles may be applied for the extractions or the separations of metal ions from liquids, e.g. from waste liquors leaving galvanizing, printing and metal working industries. The particles are of a spherical shape, have a bulk density of at least 0.5 g/cm3 and are resistant against acidic liquids. The in...

An actuating mechanism is disclosed as particularly useful for a braking assembly, and especially for a disc brake assembly. The mechanism is a device having elastic properties formed from a plurality of layers, or laminae of rigid (metal, hard plastic) and resilient (elastomer, rubber) members bonded together and to the inside of a casing or caliper housing sealing it therein. The casing together...

The bond strength between a sulphur-vulcanizable rubber and a metal, especially brass, is increased by using as bonding promoter a compound having the formula [-O2C CH2S-B-S CH2CO2-]M++ or a hydrate thereof, where B represents a divalent organic radical and M represents cobalt or nickel.

Syntactic foam with improved processing characteristics is disclosed wherein a blend of aminosilane and aminated alkylphenol alkoxylates are used to improve processibility and reduce cure time of the syntactic foam system.

Good adhesion of rubber to metal is very important in rubber articles containing metal reinforcement. For example, in a steel belted tire good adhesion between the tire rubber and the metal tire cord is of utmost importance. Good metal to rubber adhesion is also of great importance in a variety of other rubber products, including power transmission belts, conveyor belts, and rubber hoses containin...

There is disclosed a method for adhering rubber to reinforcing materials which comprises embedding a textile fiber or metal reinforcing material in a vulcanizable rubber composition comprising rubber, a vulcanizing agent, reinforcement, a methylene donor, and a phenolic ester as a methylene acceptor.

Contacting cured addition-type cured silicone material with hydrogen gas suppressing materials which are compounds containing phosphorus, sulfur, nitrogen, or aliphatic unsaturation reduces or eliminated the undesirable hydrogen gas generation. Examples of such hydrogen gas suppressing materials are triethylphosphine, gamma -mercaptopropyltrimethoxysilane, N,N-diethylaminoethanol, 3-methyl-1-buty...
