CONSTITUTION:A V-belt 32 is wound round both a driving pulley 24 and a driven pulley 34, in both of which the distance between th...

A lock-up control system for a lock-up type automatic transmission is disclosed where the transmission output torque is monitored and the interruption of the lock-up action is executed after the transmission output torque has satisfied a predetermined condition after generation of a command for shifting within the transmission.

A system for controlling an electromagnetic clutch of an internal combustion engine mounted on a vehicle, in accordance with the engine speed and vehicle speed. The electro-magnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a magnetizing coil provided in the drive member, and a driven member adjacent said drive member. A shift lever switch produces a sign...

A heat-shrinkable elastomer having a first length is produced by uniaxially orienting a copolymer having alternating polyamide and polyether block polymer segments to a second length substantially greater than a third length at which partial permanent deformation occurs. Upon removal of the tensioning force, the stretched elastomer naturally relaxes to the third length which is substantially great...

AUTOMATIC MONOCHROMATOR-TESTING SYSTEM An automated chemistry-testing system for analyzing serum samples in which a controlled intensity, monochromatic light beam of substantially any desired wavelength can be selectively directed through any one of a plurality of test solutions in a spectrophotometer. The system operates at very high speed, permitting serum test solutions to be scanned with a mul...

"Improvements Relating to the Manufacture of Tobacco Smoke Filters" A particulate plastics material, a polysaccharide and water are fed to an extruder which is operated under such heat and pressure conditions that upon emergence of the extrudate from the extruder die, the extrudate assumes a cross-section greater than that of the exit orifice of the die.

The approaching end of usable ink ribbon which is being supplied from a cassette to a serial printer is signaled when a detector member which rides on used ink ribbon as it is wound onto the take-up spool of the cassette, reaches a predetermined distance away from the axis of the take-up spool and moves to project through an opening in the cassette. The wall of the cassette serves as a barrier to ...

A process for the gasification of sewage sludge or other carbon-containing waste materials in a gasifier (1) is described. A solid fuel and oxygen-containing gas are also fed into said gasifier. The residues formed during gasification collect at the bottom of the gasifier in the form of molten slag. Gasification takes place in a fluidized bed (9) formed above the slag bath and constituted by the d...

In a process for producing polyurethane foam by allowing a reaction mixture comprising at least one polyisocyanate component and at least one polyfunctional active hydrogen component to react, a compound selected from the group consisting of oxynitrate salts of metals of Group IV B of the Mendeleef periodic table, is employed as a cell opening additive. Such oxynitrate salts are also effective to ...

N-Aminoalkyl(perfluoroalkanoylaminophenyl)sulfonic acid amides of the formula: in which R1 is perfluoroalkanoylamino of 2 to 4 carbon atoms, in 3- or 4- position of the benzene ring; R2 is hydrogen or alkyl of 1 to 4 carbon atoms; R3 is hydrogen or straight or branched chain alkyl of 1 to 4 carbon atoms; R4 is straight or branched chain alkyl of 1 to 4 carbon atoms; and n is one of the...

A brake system intended for automotive vehicles provided with a brake pressure transmitter (1) which is linked to the wheel brakes through pressure medium lines, and with sensors (19 to 22, 24) which are responsive to the brake pressure or to the behavior of rotation of the wheels and by means of which the braking effect at the wheels brakes is detectable. Furthermore, separating valves (SO1, SO2,...

PURPOSE:To efficiently form PTP pockets by a method wherein the pocket formation part of a raw multi-layer laminated sheet containing a high density polyethylene intermediate layer are heated locally up to a pre-specified core temperature and, after that, said sheet is pinched by mold and the pocket non- formation part of the sheet is cooled and finally plugs, which are heated up to a specified te...
