PURPOSE:To realize short-period charging and prevent drop of efficiency under a low temperature by forming a particular electrolytic material in the vicinity of electrodes of a battery. CONSTITUTION:An original electrolyte is obtained by mixing those where a metal salt such as aluminum, zirconium, potassium, barium, calsium, magnesium, germanium, niob and titanium is dissolved or suspended to the ...

An electron emission system includes a high-brightness field-emitter cathode. Advantageously, the tip of the cathode is shaped to minimize structural variations caused by surface tension forces. In addition, an electrode assembly associated with the cathode is designed to establish electric field forces that are opposite and at least approximately equal to the surface tension forces acting on the ...

A method for preventing the irregular untwisting of yarn ends in pneumatic yarn splicing apparatus. The respective free yarn ends to be spliced are untwisted and loosened in the control nozzles and each untwisted yarn ends is cut at a predetermined position thereof. The cut yarn ends are overlapped in a splicing hole and spliced by the jetted fluid stream.

Beating and cutting edges (24), Fig. 2, entraining surfaces 25, and crushing edges 26 may also be provided at the disc peripheries. Material for fragmentati...

Novel, multiple-tritiated steroid-20,17- spirolactones of general Formula 1 wherein -A-B is -CH2-CH2-, -CH=CH- or and R is hydrogen or tritium and n is 0 or 1, are usable as tracer materials for the detection of mineralocorticoid receptors.

Dispensing device, especially for yarns, consisting of a container for receiving a yarn roll formed from a winding core and from a yarn package, the yarn roll (1) being mounted freely rotatably in a cavity (6) of matching shape to the container (2), and the free yarn end (18) of the yarn thread being guided out of the container (2) through a gap, the gap extending at least along a part region of t...

The invention relates to a method for determining the spatial content of spaces, especially subterranean spaces, such as for example cavities, caverns, caves and the like. The essence of the invention resides in the fact that the volume of a medium filling the space being studied is changed by a sudden and short-lived increase or decrease in volume. In this arrangement, the pressure prevailing in ...

Method and apparatus for splicing the ends of spun yarn includes means for inserting the yarn ends into a hole associated with a splicing nozzle having one or more air jet pipes, in which hole the ends are subjected to an air jet to join them each other. Yarn end control nozzles for the yarn on the package side and the yarn on the bobbin side are disposed at each end of the splicing nozzle to suck...

PURPOSE:To obtain a high-lug (deep-groove) tire of a high quality with limited fluidization of rubber during the vulcanization by partially cutting off the tread portion of an green tire to form a pattern groove before the unvulcanized tire is mounted into a mold to vulcanize. CONSTITUTION:The treaded portion of an green tire 5 is partially cut off to form a pseudo pattern groove in a roughly comp...

A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member. The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag. After the core is pressed coaxially on the tie strip so as to indent the member and thus pr...

A safety binding adapted to be mounted on a ski comprises a one-piece jaw in which engages and is maintained one end of the sole of a ski boot, this jaw being urged under the action of a resilient device against two support lines provided on a rear transverse face of a support member. The support lines, viewed along the axis of the ski, converge towards a point located above the ski. The resilient...

A method and apparatus for producing particulate directly from a supply of molten material by the use of a rotating member having discrete serrations in the periphery thereof. The leading surfaces of the serrations contact the molten material and propel a portion into a cavity formed by the surfaces of the serration while under the effect of a surface of a dam means, in proximity to which the serr...
