PURPOSE:To keep a clutch from a shock and abrasion at the time of changing a speed by multiplying and reducing the speed change step when a velocity difference is caused short of a shock and abrasion at a clutch at the time of changing over the clutch. CONSTITUTION:During a certain speed step, a speed change gear is adapted to conduct multiplying operation when the relative rotational frequency Nu...

PURPOSE:To improve drivability and emission during highland running by deciding the running altitude of a car according to a detection signal of a running condition detecting means and switching a shift pattern according to the decision. CONSTITUTION:A control circuit 4 is adapted to select a shift position corresponding to a running condition with parameters of an engine load according to a signa...

A method and device for separating liquid mixtures by ultrafiltration wherein prior to introducing the mixture into the ultrafilter a gas is added to the said mixture. The addition occurs at a pressure higher than the ultrafiltration pressure and the mixture of liquid and gas is allowed to expand down to the said ultrafiltration pressure prior to be introduced into the ultrafilter.

The invention relates to a precursor for an electrical storage lead battery which can be converted into an operative storage battery by the mere addition of a sulphuric acid electrolyte. This precusor which has an unlimited shelf life consists of positive plates, of negative plate dispersed therebetween and of separator plates inserted between adjacent positive and negative plates and of a housing...

Packaging for yarn reels characterised in that it consists of housings intended to accommodate and guide the rotation of at least one reel, closed by a lid 5 provided with a slot for the passage of the yarn, a means 12 for stopping the end of the yarn also being provided. ;

A lamp socket assembly for use with a printed circuit, particularly where the mounting aperture in the circuit board is relatively small and the board may be remotely located. The assembly includes a lamp socket and a separate key member. The key receives the socket in latched relation therewith, the latching arrangement being such as to afford limited longitudinal displacement of the socket relat...

A device for automatically loading a bead core to an apparatus which associates an elastomeric filler with the bead core and for unloading the bead core with the filler. The device has two jaws for loading the bead core and means for controlling the opening of the jaws. The jaws are opened when the bead core is locked in the apparatus and the jaws are moved from the apparatus towards the loading p...

The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a handle extending out through a longitudinal slot in the shaft. The rib carrier is slidable by means of the handle between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the c...

A process for reducing micro-voids in cross-linked cable insulation without reducing the voltage breakdown strength thereof in which process the insulation, after cross-linking, is heated at a temperature in the range from about 120 DEG C. to about 150 DEG C. and under a pressure less than 10 mm. Hg for a period from about 8 hours to 48 hours. Also, a cable having such insulation which has micro...

Cementitious compositions having a modulus of rupture greater than 20 MN/m2 are prepared by subjecting a mixture of hydraulic cement, fine aggregate, a selected water-dispersible polymer and water to a homogenisation process (in order to very substantially reduce voidage in the product) and by thereafter curing and drying the product. The aggregate improves the modulus of rupture and resists any l...

A process for rapidly forming dilute aqueous solutions of water-soluble polymer from gels of such polymers is provided. In the process polymer gel is extruded, cut, and slurried in water. The slurry of gel particles is subjected to high shear forces immediately after slurry formation to form a slurry of very fine gel particles. The slurry of fine gel particles is mixed with additional water under ...

1. Phenolic resin compositions suitable for the manufacture of phenolic prepreg mats, according to which the compositions employed for impregnating the fibre mats consist of phenolformaldehyde resins of the resole type, fillers, pigments and hardening agents, characterized in that these compositions contain an additive consisting of at least 20% by weight of an alkali or alkaline-earth metal metab...

Filiform elements of predetermined resistivity, e.g. selectively destructible leads of an electrically programmable read-only memory, are formed on a semiconductor substrate such as a silicon body by first depositing thereon a layer of dielectric material such as SiO2 and topping that layer with a conductive or nonconductive coating which is resistant to a chemical such as hydrofluoric acid capabl...
