An oil pressure control means for operating an automatic transmission for automobiles in a manner to establish various speed shift stages in accordance with the balance of the throttle pressure and the governor pressure, including a combination of a brake-sensitive control means operating in response to operation of a brake pedal and an oil passage change-over means, said combination being adapted...

A ratio control system for a continuously variable transmission performs a feedback control wherein an integral control gain and a proportional control gain are varied depending upon the level of a line pressure that is used to actuate a pulley unit during shifting operation.

A method and apparatus is disclosed for serially winding a high speed running yarn onto bobbins without yarn stoppage between bobbin changes, and without loss of yarn. The method and apparatus includes at least two bobbin receiving chucks which are adapted to be serially delivered to a winding position. When the first bobbin becomes full, it moves laterally away from the yarn traverse guide, and t...

1. Apparatus for placing woven tubes (10) which are to be filled with paste-like active material in the manufacture of tubular electrodes of lead accumulators onto their pertaining filling tubes (15) through which the active material is pressed into the woven tubes which are thus being stripped off the filling tubes, the apparatus providing guide pins (1, 20, 40) for taking up the woven tubes (10)...

There is disclosed a circuit arrangement comprising a microcomputer, wherein certain terminals of the microcomputer may be used as either input terminals or as output terminals under selective switching control so that a reasonably priced microcomputer with few terminals can be used to control complex functions such as those of a vehicle seat adjusting mechanism. The circuit arrangement also inclu...

Self-engaging ski binding comprising substantially identical front and rear stops which each comprise a slide (36) provided with triangular cams (42) interacting with the rim of the sole of the boot and which can be moved relative to a runner (32) against an elastically compressible force developed by an adjustment mechanism (90, 92, 94) housed in the slide (36).

A release ski binding having a sole plate which is pivotal in its central region about a generally vertical axis and can be forwardly pivoted about a transverse axle which is arranged in front of the vertical axle, which sole plate is held in the skiing position by a resilient holding mechanism which, during a release, effects an opening of the elements which hold the ski shoe to the ski. In order...

The present invention relates to a safety binding of a boot on a ski which comprises two lateral jaws (2) mounted for movement under the force of an elastic member (5) between a closed service position in which these jaws coact with the sole of the boot (C) and an open position. It also comprises structure (3) interacting with the heel of the ski boot and having a sole grip member (29) mounted for...

1. Use of a concrete mixture or cement mortar mixture of unadulterated portland cement with high sulphate resistance, aggregates of a carbonate rock (preferably dolomite crushed sand and/or limestone crushed sand), water and optionally further additives such as a hydroxide (preferably calcium hydroxide and/or magnesium hydroxide) and/or an agent for sealing and making hydrophobic the set concrete ...

A method is presented, for use in borehole drilling for correcting errors in azimuth determination resulting from variations in the earth's magnetic field to which a measuring instrument is exposed. The method distinguishes between variations in the earth's magnetic field caused by the drillstring and variation caused by external sources, and the method corrects only for errors caused by the drill...

A bottle of a thermoplastics polymer material, eg polyropylene, which is naturally translucent for e.g. tomato ketchup is externally coated with a polymeric coating material such as an acrylic or a polyurethene, the coating counteracting the effect of the translucent bottle wall and making it more transparent and so improving the visual appearance of the product whilst also giving the bottle a hig...

An automatic clutch control system is disclosed where a first servo loop for controlling clutch actuating means when the engine is idling, a non-drive range (P,N of 20) of the transmission (14) having been selected when the vehicle is at standstill, includes means (1300) for storing an operating parameter related to the engine idle speed for example a target engine speed or the speed detector of a...

An apparatus for use with an oil well drilling apparatus, includes an annular spool 20 interposed permanently between the well blowout preventer stack 14, 15 and the upper bell nipple 16. The spool receives a plurality of different mandrels, including a test mandrel for testing the seals of the blowout preventers or adapting the drilling apparatus for wireline operations, and a shut-down mandrel f...

A process is provided for the production particularly of heat insulating building elements, in which a mixture containing fibrous vegetable matter, mainly rice-shell, binding material, e.g. cement or plaster, and water is prepared, then moulded. In the first step the vegetable matter is mixed with liquid (prewetting), which contains part of the mixing water and dissolved bond-improving agent. Dry ...
