PURPOSE:To detect the calorific value of a clutch, promptly, for preventing the clutch from being overheated, by obtaining a speed difference between a cluth drive shaft and a clutch driven shaft so that a timer is actuated after the duration of a time set by the timer when the speed difference is above a reference value, for changing the coupling characteristic of the clutch. CONSTITUTION:A crank...

PURPOSE:To prevent the occurrence of a major accident by automatically confirming an obstacle in front and applying brakes at the time of setting a change gear to the third-gear or the top-gear position. CONSTITUTION:In an automobile which transmits the power of an engine 2 to wheels 5, 5' via a change gear 3 and a differential gear 4, a limit switch 10 is provided on the lower portion of the chan...

A transmission control system for a motor vehicle provided with a clutch and a continuously variable transmission. The transmission has a spool valve (40) controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. The transmitted torque (TD) in the transmission system is detected and a desired clutch torque (TC) dependent on the transmitted tor...

An arrangement for manufacturing non-pelletized packaging units which are completely surrounded with shrinking foil. The packaging units are formed by several layers of objects which are stacked on top of each other in such a way that at least two parallel recesses are formed into which support members of a lifting device can engage. The arrangement includes a single shrinking foil application dev...

Coacting die cylinders (10, 12) with one cylinder (10) having a cutting blade (14) and the other cylinder (12) having an anvil surface (16) which when rotating cooperate to cut a blank from a web of low density material. The blade and the anvil surface (16, 22) are tapered in opposite axial directions so that the clearance between them can be readily varied and adjusted by moving the cylinders (10...

Die Funktionen M(y) und M(n) zwischen dem Moment M des Motors, der Position y des Gaspedals und der Drehzahl n werden in einer elektronischen Steuereinheit (13) gespeichert, wo die zum gemessenen Gassignal und zum gemessenen Drehzahlsignal gehörenden Momentwerte ausgesucht werden und ein Belastungssignal s erzeugt wird. Das Signal s wird mit einem Konstanten Aufschaltungs- Belastungswert Sf und mi...

A bobbin magazine (70) for mounting on an end plate (48) of a travelling service tender comprises a band movable on an endless path, compartments (84) on the band to receive sticks of telescoped bobbins (86) and a transfer device to transfer sticks from the magazine to the tender. The magazine can be hinged to the tender so that the magazine can be swung out to expose the end plate.

The invention relates to a pressing device for three-knife trimmers for trimming books or unbound books having a mechanical drive for lowering the die down to the stack of books or unbound books and having a spring, which is articulated via levers, for exerting the pressure in such a way that the spring exerting the pressure is composed of a spring assembly 5 which is arranged about an axis of rot...

The invention relates to a process for starting a vehicle with repeated forward-reverse run, in course of which in the drive-chain of the vehicle an automatic transmission /2/ is driven with an internal combustion motor /1/ through the incorporated hydrodynamic torque converter /16/ or in a given case with a dry friction clutch /15/ shortcircuiting it, either directly with the automatic transmissi...

The functions M(y) and M(n) between the torque M of the engine, the position y of the accelerator pedal and the speed of rotation n are stored in an electronic control unit (13), in which the moment values pertaining to the measured acceleration signal and to the measured speed of rotation signal are picked out and a load signal s is generated. The signal s is compared with a constant shifting-up ...

A vehicle guidance system for a tractor has a horizontal scanning laser on the tractor and a target arranged to return the laser beam along its path. When returned laser light is detected, indicating alignment of the beam with the target, the angle of the beam relative to the tractor axis illustrates the steering correction required. The target has an array of beam reflecting elements patterned to...

PURPOSE: To exclude a part by taking the image of the surface of the part using an image pick-up camera, changing the image to digital data, and then confirming the crack on the surface of the part. CONSTITUTION: A part 1 whose crack is to be identified can be moved by an operating device 2 and is placed in front of a color television camera 3 with a ray filter 5. The camera 3 generates a signal t...

A quick connect fitting for tubing which can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a snap-on cap, the gland and the cap having complement...
