A control system for a motor vehicle provided with a continuously variable transmission. The transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device of the transmission. When a throttle valve of an engine is rapidly opened, the line pressure is increased so as to prevent a belt of the pulley device f...

PURPOSE:To prevent slippage of a belt due to the line pressure by providing a means for detecting an abrupt variation of the engine torque or the speed change ratio and setting the line pressure at the maximum value in a driving section independently from the target line pressure upon the occurrence of an abrupt variation. CONSTITUTION:The variation of the throttle opening is detected in a throttl...

A control system for a continuously variable transmission for a motor vehicle has a line pressure control valve having a spool for controlling oil supplied to a cylinder of a driven pulley to change the transmission ratio. The control system operates to increase the line pressure when the vehicle stops. The increased line pressure actuate the cylinder thereby increasing the transmission ratio.

A control system for a continuously variable transmission has a spool valve for controlling line pressure of oil supplied to a cylinder of a driven pulley to change the line pressure. The line pressure control valve has chambers at opposite ends of the spool. Pressure of oil supplied to an end of the spool is controlled by an on-off control valve in accordance with engine operating conditions to c...

A hydraulic, overbraking mechanism for a self-circulating fluid brake, cyclone brake, consists of a spring-loaded plate. The plate is provided with slots in such a manner that larger or smaller areas of the rotor blades are activated when the plate, on account of the hydraulic vacuum, presses the loading springs together. In this way, the power of the fluid brake is increased, overbraking begins a...

The invention relates to the optical control of sufficiently transparent bodies, in particular articles such as bottles (B) or flasks distributed in line on a horizontal table conveyor in front of the apparatus, each light emitter (21) of which can be reduced to a simple screen providing a luminous background. Rapid electronic examination is carried out by lines, in the direction of motion ov...

In order to permit the introduction of a biopsy needle (14) into a breast (19) examined with a mammograph, a structure is made in the form of a crank bearing via its arm (22) the needle holder (15) and supported via its shaft (21), vertically, in the direction of a tumour (12) situated in the breast, the position of which tumour has moreover been calculated. The distance (D) of penetration of the ...

An apparatus for disintegrating essentially organic refuse, such as coarse rubbish, shrubs or the like, with a disintegrating device to which a conveying element is assigned, is to ensure a uniform grain size and good defibration of the fed material together with a good disintegrating effect. For this purpose, the disintegrating device is a defibration or beating rotor (24) above a travelling grat...

A multiplicity of bobbins (12, 14) are arranged in pairs in the bobbin creel (2) of a thread-processing machine (22). Each bobbin pair (10) consists of a feed bobbin (12) and of a reserve bobbin (14) which are assigned a common head thread-guide (18). Each bobbin pair (10) is arranged in the creel frame (8) in such a way that, together with the common head thread-guide (18), it can be drawn latera...

A rotary cutting device for material webs consists of a machine frame with rollers supported in pivot bearings on the machine frame, driven by rotary drives and defining a cutting range, namely a cutting roller and a counter cutting roller, which form a roller gap for feeding the web material between them within the cutting range. The cutting and counter cutting rollers are supported so as to roll...

A front cover has at a front surface central portion thereof an integral mounting seat for installation of a mounting bracket and at a rear surface central portion thereof an integral boss adapted to extend between the mounting seat and a front end of a cylinder head and cylinder block assembly. The boss is fastened together with the mounting bracket to the front end of the cylinder head and cylin...

Polyurethane syntactic foam compositions having high glass transition temperatures and low coefficients of thermal expansion suitable for use in tooling applications as modeling stock are prepared from polymeric isocyanate, an amine-based polyol, a polyether triol, molecular sieve material and hollow microspheres.
