PURPOSE:To perform adequate control of full engagement of a clutch by generating a fully engaged clutch signal when such detection is made up that the rotation ratio between engine rpm. and revolution speed of the output shaft of a transmission gear is maintained constant for a specified period. CONSTITUTION:Sensors for detecting rpm. of an engine and revolution speed of the output shaft of the tr...

PURPOSE:To prevent an engine from unexpected hault or so by changing over a clutch into the start control condition where the engaging force thereof is enhanced according to rpm. of the engine if the rpm. is reduced below a specified value with the clutch under control for full engagement. CONSTITUTION:An operation control means for an automatic clucth which is interposed between the output shaft ...

Some secondary and tertiary straight and branched chain amides and amines were found to be highly lethal to nematodes and other helminths.

Method and apparatus for building annular tire components such as steel cord tread reinforcements, in which a measuring drum is employed to receive strip material and simultaneously to feed it to a component building former. The strip material laps a portion only of the measuring drum, and a measured length of the strip is severed on the measuring drum and the major portion of the length of strip ...

1. A process for the preparation of a resilient foam based on a melamine/formaldehyde condensate by foaming an aqueous solution or dispersion, which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent, with or without conventional additives, and then curing the foam, wherein a) the concentration of the precondensate in the mixture of preconden...

A filled thermoplastic composition is produced by first preparing a masterbatch of an impact polystyrene, a rubber, an oil and a filler and by secondly mixing the masterbatch with a polystyrene composition. The filled thermoplastic composition has acceptable properties.

A formed epoxy resin composition comprising a condensed epoxy resin and pentabromodiphenylether; the use of pentabromodiphenylether alone or with other brominated diphenyl ethers as a flame-retardant agent for compositions containing epoxide resins especially fibrous substrates of glass and/or cellulose fibers containing epoxide resins therein.

1399302 An oligocarbonate GENERAL ELECTRIC CO 6 Feb 1973 5889/73 Heading C2C [Also in Division C3] An oligocarbonate containing 5 repeating units is prepared from tetrabromobisphenol A, phosgene and tribromophenol.

The gas discharge panel disclosed in this application is composed of parallel electrode groups, a dielectric layer for covering the electrodes and a gas discharge space or gap in which a firing spot is produced through the discharge space via the dielectric layer when an electric signal is applied to the electrode pairs. The above-mentioned dielectric layers provide a suppression layer having a pr...

Information is conveyed from a downhole location within wellbore being drilled by producing pressure and velocity of flow variations from the steady state drilling fluid pressure and velocity of flow so as to get up transient acoustic waves that propagate to the surface through the drilling fluid within the drill string, and a simple and reliable method of recovering the propagated information is ...
