PURPOSE:To enhance the freedom of control, by holding a solenoid valve in a uniform condition within a predetermined width around a pressure at which a shuttle valve is changed over. CONSTITUTION:A shuttle valve 5 takes a first position when pressure below an engine load proportioning pressure but takes a second position when pressure exceeds another engine load proportioning pressure. At the abov...

PURPOSE:To enhance the freedom of control, by controlling shift-down timing or brake while a solenoid valve is set in a predetermined condition within a predetermined width within which a shuttle valve is changed over, and by allowing brake friction elements to hold its operative condition within first and second brake ranges. CONSTITUTION:A shuttle valve 5 takes a first position when pressure bel...

PURPOSE:To satisfactory sustain the durability of a frictionally engaging device, by increasing the line pressure of a hydraulic control device only during an engine exhaust brake device being operated so that fuel consumption and gear shift feeling during normal travel are sustained. CONSTITUTION:An oil pump 12 sucks up oil from an oil pump 10 generate a basic oil pressure, and a primary regulato...

PURPOSE:To satisfactory sustain the durability of a frictionally engaging device, by increasing the line pressure of a hydraulic control device only during an engine exhaust brake device being operated so that fuel consumption and gear shift feeling during normal travel are sustained. CONSTITUTION:A basic hydraulic pressure generated by an oil pump 12 is regulated by a primary regulator valve 14 t...

PURPOSE:To prevent shocks and slips which generate during starting or gear shift operation, by associating the engaging force of a clutch which is changed in accordance with the rotational speed of an engine, with a gear position of a transmission gear so that the engaging force is changed in accordance with a gear ratio at that time. CONSTITUTION:When a vehicle is started, a lever is shifted to a...

PURPOSE:To prevent function of an automatic brake against temporal stoppage for putting into a barn by producing an output signal with a time lag against the stop detection signal during occurrence of a back speed change position detecting signal. CONSTITUTION:It is comprising an automatic parking brake system, a parking brake mechanism 10, a motor mechanism 20 and an electric control circuit 30. ...

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone int...

Prior to the actual splicing process, a preparation process is carried out in a preparation apparatus. The apparatus comprises a preparation tube having one or more circumferentially arranged air jet nozzles. The axis of each nozzle is inclined to the axis of the preparation tube and has a mouthpiece at the inlet end. The yarn end to be prepared is introduced into the preparation tube, where it is...

An automatic selvedger has a pair of longitudinally spaced and transversely throughgoing main rolls rotatable about respective parallel axes and guides and a drive that pass the web longitudinally and continuously from one of the main rolls to the other main roll in a travel direction perpendicular to the roll axes and with the web spanned tightly longitudinally between the main rolls and lying ge...

The apparatus comprises shredding means comprising at least one metallic rotor and at least one rubber stator, and a housing therefor. A stepped slot for the ejection of metal may be provided in an inclined transit passage between two shredding stages. Thus sabotage by the insertion of a metal bar can be countered.

A protective composition which comprises at least one aliphatic polyisocyanate, at least one aromatic polyisocyanate and a solvent.

A machine for applying a configuration of reinforcement/stiffening or decorative material in powder form to a receiving surface (20), for subsequent fusing, cooling and pressing to a substrate such as shoe upper. The machine comprises a deposition station (12), a heating station (14) and a press station (16). A tensioned receiving belt (20) receives the configuration of powder through a cut-out (4...

A machine sequentially manufacturing a plurality of reinforced substrates such as shoe uppers, comprising a powder deposition station (30) wherein a stencil assembly (42) [Fig. 6] applies powder onto an annular receiving belt (22), the powder being applied in a three- dimensional configuration because of a peripheral spacing element arranged on the cut- out between the stencil (42) and the receivi...
