PURPOSE:To previously prevent the deterioration of the speed change characteristic by regulating the variation of the engine torque according to the frequency of speed change in warming when the good speed change characteristic is maintained by varying the engine torque by a prescribed quantity by the delay angle control in speed change operation. CONSTITUTION:The speed change stage of an automati...

PURPOSE:To improve responsiveness to the rotary speed control of a driving wheel, that is, to improve responsiveness to an antiskid control by assuming a speed change control such that the inertia of a drive system is made smaller at the time when antiskid actuation is detected. CONSTITUTION:An antiskid means B, which includes a speed change means A where speed is changed by controlling the hydrau...

Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure. Subsequently a pressure relief system permits the tires to exhaust faster than the vessel. Each tire is prepared for retreading by applying a bond...

The invention relates to a self-locking device which makes it possible to adjust, with the aid of the armrests, the slant of the backrest of an armchair having a plurality of use positions. This device comprises a rack-mechanism toothing 12 which is securely fastened to each armrest 9 and an oscillating element 10 mounted at the upper end of the legs 1, 2 in order to engage automatically the rack-...

A vehicle gearbox has a brake for dampening idle rattling, which is in this case in the form of a conical frictional surface on the low-speed gearwheel on the output shaft and a brake cone carried by a disc fixed to the output shaft. The disc and the cone have coacting structure which presses the cone against the frictional surface when the low-speed gearwheel rotates more rapidly than the output ...

Compositions of water soluble polymers coated with hydrophobic fumed silica are readily dispersed in water. A method for improving the water dispersibility of a water soluble polymer is disclosed.

Vinyl chloride (VC) resins, particularly poly(vinyl chloride) (PVC) and chlorinated poly(vinyl chloride) (CPVC) are reinforced with glass fibers which have been sized with a particular aminosilane coupling agent and a particularly chracterized basic film former. At the processing temperature of VC resin, containing a stabilizer against degradation during thermoforming, for example in an extruder, ...

A pulse driven self-shift plasma display panel characterized by having meander type shift channels for shifting a discharge spot. Each meander type shift channel is composed of an array of discharge cells defined in the discharge gap at the crossing points of electrodes arranged on parallel substrates, the electrodes on one substrate being oriented generally transversely to those on the other subs...

Resilient polyester foam materials. Acyl halide, polyol, and polyhydroxy cross-linking agent are reacted in the presence of alkali metal carbonate to prepare the resilient polyester foams. A process similar to that used in the one-shot preparation of polyurethane foams is used. Preferred reactants are adipyl chloride, quadrafunctional polyol based on pentaerythritol, propoxylated pentaerythritol c...

Compositions of water soluble polymers coated with hydrophobic fumed silica are readily dispersed in water. A method for improving the water dispersibility of a water soluble polymer is disclosed.

Crude glyceride oils are refined by membrane filtration under pressure in solutions in organic solvents, particularly to separate phosphatides, which may also be refined according to the invention. The solvents are non-acidic, non-hydroxy solvents, e.g., esters, hydrocarbons and halogenated hydrocarbons, particularly in which micelles are formed and the solution is contacted under pressure with a ...

The invention relates to a dry-shaving apparatus with a housing (1) which comprises a holder (2) for at least one cutting unit (3), which cutting unit (3) comprises an external cutting member (4) which is formed with hair-entry apertures (5) and which is movable relative to the holder (2), an internal cutting member (6) which is drivable relative to the external cutting member (4), and a retaining...

For the reduction gear of a drive of an appliance for removing and conveying mineral raw materials from the sea bed, with a scooping body consisting of two drums arranged concentrically one in the other, there is provided a design, as a result of which the influence of flexions of the drum and of the gear casing on the tooth meshing on the large wheel is eliminated virtually completely. For this p...
