A method of producing high yields of olefins from hydrocarbon feedstocks which is particularly applicable to heavy hydrocarbons. In accordance with the present method, a stream of gaseous oxygen is introduced into a first reaction zone and a cocurrent flow of hydrogen is introduced about the periphery of the gaseous oxygen stream, the hydrogen being introduced at a temperature at which it will spo...

A mechanically stable, piezoelectric print head for an ink jet printer has ink channels formed by a channel matrix that consists of a row of piezoelectric strips disposed in spaced parallel relation next to one another, covered by a plate on both sides. The channels thus formed directly institute the printing nozzles.

Apparatus for accumulating stacks of paper sheets has a cross cutter which repeatedly severs several overlapping running paper webs to form a series of groups of overlapping sheets. Such groups are accumulated into layers at a gathering station, and successively formed layers are engaged and withdrawn by a transfer unit which delivers the layers into the range of a withdrawing conveyor serving to ...

PURPOSE:To simplify a mechanism and to enable a thread to be supplied easily intermittently, by a method wherein a swing arm is vibrated with a rotary solenoid moved, and a thread, passing through a thread passage guide, is intermittently passed between the nip formed by nip rollers. CONSTITUTION:A thread 9 runs downward from above in a manner that it passes through a thread passage guide 8 and a ...

In a particle separator for sorting particles suspended in a liquid according to certain characteristics, a change in the droplet breakoff point of a liquid jet stream which is subjected to vibrations is detected. The vibrations, generated by piezo-electric crystal 24, produce, on the surface of the jet stream 16, undulations, the amplitude of which is monitored at a fixed point 21 on the jet stre...

A pellicle for use in projection printing comprises a pellicle in which the transparent film is formed from a polyvinyl butyral resin or from a casting composition which is a mixture of polyvinyl butyral resin and a dispersion of colloidal silica and a silicone resin which is a lower aliphatic alcohol-water solution of the partial condensate of a silanol. A pellicle employing such films are useful...

A socket 3 is moulded to a thermoplastic tube 7 by heating a portion 14 of a plastic tube 7 to the deformation temperature and after having placed this portion 14 in a mould 1, said portion is subjected to a gaseous wave of about 30 atm. which strikes said portion in less than 0,2 seconds against the mould wall of a mould space 2 corresponding with the shape of the socket 3. The still hot socket 3...

PURPOSE:To arrange the end parts of optical fibers at positions separated from an object by a prescribed distance and to keep a flatly expanded direction at a prescribed direction for the object by attaching a head part of an optical fiber sensor to a fitting base plate. CONSTITUTION:When the head part 1 is to be attached to the fitting base plate B, a notched part C is previously formed on the ba...

PURPOSE:To improve the efficiency of heat accumulation, and to reduce floor space occupied by distinctly separating the inside of a heat accumulating tank into upper and lower sections as a high temperature tank and a low temperature tank by a baffle plate to form the inside of the tank to a vertical multilayer type while encasing and arranging pipings to upper and lower sections in the heat accum...
