1451464 Helical conveyers J R E WAHREN 17 Oct 1973 [25 Oct 1972] 48449/73 Heading B8A Vertical, endless, guided helical loops form means for collecting, accumulating and disstributing objects between continuously movable conveyer tracks leading to and from treatment stations. In Fig. 1, machine parts requiring a series of operations are conveyed between work stations by conveyer tracks intersperse...

1. Process for the production of sugar crystals from sugar juices consisting in feeding a continuously operating apparatus for crystallisation by vacuum evaporation (10) with a magma made up of syrup and crystals, in introducing the juice to be processed into this apparatus at points spaced out from the inlet to the outlet of the latter, in withdrawing from this apparatus a massecuite which is sub...

A threaded pipe joint including male and female sections, each with corresponding closed angle threading. Cooperating abutments are on the respective male and female sections. The closed angle threading diminishes in height in the region adjacent the abutments, which limit axial movement of the sections with respect to each other and thereby prevent movement which would permit the closed angle thr...

A button cell having an air cathode characterized by having a cathode can 21 with air access port 16 in an essentially flat bottom 23. Air cathode 29 is positioned with its hydrophobic portion 28 abutting flat bottom 23 and grooves 25 or 25a are provided in the central portion of the interior of bottom 23 of cathode can 21 or in abutting hydrophobic portion 28 of air cathode 29 respectively.

An electrochemical cell includes an anode and a cathode electrochemically coupled by an electrolyte, means such as porous electrochemically non-conductive material placed within the anode and cathode to permit minimal electrode separation, and a cell housing which can be sealed hermetically or non-hermetically. According to the invention a novel electrochemical cell comprises a sealed non-met...

For reducing voltage delay in lithium-thionyl chloride cells the surface of the lithium electrode is provided with a polyalkylacrylate film containing a lithium salt, preferably lithium perchlorate, applied by means of a non-aqueous solution of the salt.

The invention relates to a rotor device, preferably a boat propeller device. The propeller shaft drives, via a planetary gear system, two propellers in the rotational direction of the shaft and one propeller counter to the rotational direction of the shaft. The propellers are dimensioned so that they absorb approximately equal torques.
