A method and apparatus for reducing a metal compound particularly iron oxide, by means of a reducing agent comprising CO or H2 or a mixture of these two gases, of which the average temperature is between 850 DEG C. and 1000 DEG C. and which has been obtained at this temperature by means of a plasma arc heater. The CO and H2 mixture is preferably obtained by heating a mixture comprising a selecti...

Method of and apparatus for preparing and splicing the ends of fibrous formations, particularly in the pressure channel of a pneumatic splicing chamber provided with a displaceable lid. Excess lengths of ends of fibrous formations to be spliced are placed within the pressure channel in overlapping substantially parallel relationship and are then cut to a desired length by cutting means such as sci...

The purpose of the invention is to provide a process and an apparatus which make it possible to produce a large amount of battery acid within a relatively short time. The technical object of the invention is to develop a process and an apparatus for t...

Hot melt compositions are disclosed from which foamed products having a fine and uniform void structure therein can be obtained. The compositions include a thermoplastic polymer preferably an elastomer such as a styrene-butadiene block copolymer, and a small amount of a salt of a sulfonated styrene polymer. Plasticizing processing aids, tackifying agents and antioxidants can be included in the com...

In the feeding of sheet material to a machine such as a tire building former a sheet is first placed on a table and one edge of the sheet is aligned with a first datum line, preferably by tilting the table and supplying floatation air under the sheet. The sheet is then picked up and moved transversely through a predetermined distance by a gripping device to align the edge with a second datum line ...

A ski safety binding is designed to allow both a dangerous bending moment exerted about a transverse axis 15 through the weakest point of a skier's leg and a torsional moment exerted about a vertical axis 24 through the skier's leg to be detected and to be used to initiate release of the ski boot 54 from the binding when the bending and/or torsional loads approach dangerous levels. The binding bas...

A laser control device (4) includes a pulse repetition interval timer (4d) and a pulse width timer (4b) that, upon each setting, directs one pulse having a predetermined pulse width to a laser system (5) that emits a laser beam in response thereto. A pulse cycle timer (42) is provided which sets the pulse width timer at preset intervals during a time period from its initial setting until the reset...

In the feeding of a strip of tire building material to a former, it is desirable to achieve a butt-joint between the ends of the strip when it has been wrapped fully around the circumference of the former (which may already have some material which has been wrapped around its surface in a previous operation). As the strip is fed to the former, its length is measured and the diameter of the former ...

PURPOSE:To produce the titled rigid particles of a large pore volume, by feeding a mother liquor containing a specified cellulose acetate to a coagulation bath comprising an acetic acid/ water solvent mixture while adding water so as to keep the acetic acid to water ratio at a nearly constant value. CONSTITUTION:A solution as a dope is prepared by dissolving cellulose acetate of a degree of esteri...

The multi-caliper brake (10) for positive torque controlling as well as for controlling the rotation of a shaft (12) has a hub (14) arranged to be mounted to the shaft (12) with a longitudinally centrally located, finned friction disc (16) mounted to the hub (14). A brake housing (36) supports multiple brake calipers (18-25) which are shown as including diaphragm operated, fluid pressure actuated ...

A method of preparing a silicone elastomer coated cloth having a surface coating of silicone resin is described. The coated cloth is elastic and pliable with a surface which has superior dirt resistance. The cloth is first coated with an addition-reaction-curing silicone elastomer composition which uses a platinum system catalyst or with an organic peroxide-curing silicone elastomer composition. T...

A catalytic converter includes ring-shaped cushion members of differing bulk densities at each axial end of a catalyzer carrier, a first cushion member which is supported by a casing of the converter being of lesser bulk density than that of a second cushion member which is interposed between said first cushion member and the adjacent axial end of said catalyzer carrier.

PURPOSE:To raise the elasticity of a honeycomb catalyst support cushion bodies for smoothening the surface thereof, and the sizing accuracy thereof, through the compression molding of corrugated knitting gauze tubes into a given form. CONSTITUTION:Corrugated knitting gauzes 2 are made by applying a corrugated roller to the knitting gauzes flatened while pressed from sidewards after shaped cylindri...
