Two embodiments of a mandrel for fabricating an air spring are disclosed. Each has a fixed diameter cylindrical portion and a portion variable in diameter to provide an extension of the cylindrical surface expandable to conic form. An array of fingers are pivotally secured to swing in radial planes to provide the variable diameter portions and are actuated by inflatable sleeves. The fingers are no...

PURPOSE:To make it possible to restrain a clutch from abruptly changing, by reducing the duty ratio of a duty signal adapted to be applied to a clutch pressure control solenoid valve, by a predetermined rate when the vehicle operating condition is shifted from a start mode into a drive mode. CONSTITUTION:A belt drive type continuously variable transmission 2 is composed of a primary pressure contr...

PURPOSE:To make it possible to eliminate a shift in line pressure due to variations, by calculating a compensating value in accordance with a hydraulic pressure and a throttle opening degree in a predetermined operating condition, and by compensating and controlling a desire line pressure in accordance with the compensating value when the control mode is shifted into an open loop control mode. CON...

PURPOSE:To make it possible to prevent an engine stall due to a delay in response by hydraulic circuit by changing over a hydraulic clutch which is controlled in several control modes, into a hold mode during specific decelerating operation when the hydraulic clutch is controlled in a drive mode. CONSTITUTION:A belt drive type continuously variable transmission 2 is composed of a primary pressure ...

PURPOSE:To make it possible to eliminate a lack in clutch pressure during accelerating manipulation so as to enhance the running ability by providing such an arrangement that, when an accelerating manipulation is performed after a specific operating condition is detected, a clutch pressure is applied to a hydraulic clutch in accordance with the degree of the accelerating manipulation. CONSTITUTION...

PURPOSE:To prevent the line pressure from being excessively increased, by compensating the gear ratio until the time of clutch lock-up if the vehicle operating condition is shifted from a start mode into a drive mode so as control the line pressure so as to decrease the same. CONSTITUTION:A belt drive type continuously variable transmission 2 is composed of a primary pressure control valve 34 as a...

PURPOSE:To make it possible to surely prevent a speed lock mechanism from being changed over into a release condition due to asymmetric brake operation, in such an arrangement that the speed lock device for holding a continuously variable transmission in a transmitting condition is released when both right and left running brake pedals are operated. CONSTITUTION:A continuously variable transmissio...

The invention relates to a method and an apparatus for concentrating substances from liquids by saturating a liquid with gas under pressure, for the subsequent expansion in a floatation cell and for the filtration of the floating material. In order, with a high efficiency, to make possible for example both a liquid cleaning and a dewatering of the concentrate obtained during the cleaning, it is pr...

An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangem...

The invention relates to a process for the preparation of alpha - beta unsaturated alcohols of the formula where R1, R2 and R3, which may be equal or different, represent phenyl, optionally substituted with one or more alkyl and/or alkoxy groups, the total number of C atoms of these substituents being at most 5, or hydrogen or an alkyl group with 1-10 C atoms, with at least one of the ...

In a device for feeding card slivers to a processing machine, which comprises at least one sliver guide (1), said guide (1) has a guiding surface (20) over which the card sliver is passed. The guiding surface (20) is constructed as a monitoring device. A guide (1) of this type is produced by a method in which the housing (2) of the guide (1) is clamped upside down by its guide surface (20) to...

Thread-splicing devices are to make a connection between two thread ends which, as far as possible, does not differ appreciably from the appearance of the remaining thread and which does not impair the further processing of the latter. The splicing of the threads by means of compressed air in a thread-splicing device is a known method for this purpose. However, the result of the spliced connection...

The invention relates to a process for the preparation of monochloromethyl chloroformate and trichloromethyl chloroformate by photochlorination of methyl chloroformate. According to the process, in a first step at 60-70@C chlorination is carried out until the ester is reacted to at most 50%, then the reaction mixture is separated by rectification and the unreacted methyl chloroformate is fed back ...

An apparatus for splicing the tow ends of man-made fiber tows, including a pair of jet carriers having oppositely directed pairs of jets to which compressed air can be supplied, whereby the connection of tow ends introduced between the pair of jet carriers is effected by aerodynamic turbulence. In order to enable an automatic splicing procedure, the pair of jet carriers is disposed on a jet carrie...

Porous electrodes for lead acid storage batteries without supporting plates or grids. The electrodes are porous, self-supporting, structurally integral and electrically continuous. Lead-acid batteries incorporating such electrodes exhibit improved performance characteristics as compared to conventional lead-acid batteries. The electrodes are made by forming a molten mixture of metal (e.g. lead) an...
