Title: Method of drying pipelines
Inventor: BAYEN JEAN
IPC: F17D3/14
Filed: 1982-09-28
Abstract: A method of drying a pipeline for transporting a gas comprises the steps of connecting a vacuum generator device to the pipeline; causing the vacuum generator device to suck moisture then being discharged; lowering the pressure in the pipeline to a value (P6) above that at which ice will form; scavenging the pipeline by introducing a dry gas at an absolute pressure above the ice formation pressure; terminating the scavenging step; and lowering the absolute pressure in the pipeline further to a maximum value (P5) limited by the vacuum generator device. <IMAGE>

Title: Solar still and method of making same
Inventor: MOSS GERALD
IPC: C02F1/14
Filed: 1982-11-03
Abstract: A solar still comprises (Fig. 1) a first chamber (11) for containing feed liquid and a second chamber (13) for receiving vapour and liquid distilled from the feed liquid in the first chamber. The chambers (11, 13) have a common wall (15) with apertures (14) above the liquid level for the passage of vapour from the first chamber (11) to the second chamber (13). The first chamber (11) has a transparent top wall (19) so that solar radiation can enter the chamber, and a dark-coloured base (18) to maximize energy retention. The second chamber (13) has light-coloured or reflective walls to reduce solar irradiation of the interior thereof, and the light-coloured or reflective common wall (15) reflects radiation thereon into the first chamber (11). Cooling liquid circulates in tubes (16) in the vapour space of the second chamber (13). The still of another embodiment (Fig. 2) is similar but has apertures (43) between the top apertures (41) and the liquid level so that there is upward air circulation in the first chamber (33) and downward air circulation in the second chamber (34) whereby vapour transport is increased. <IMAGE>

Patent GB-2138349-A (GB)
Title: Dimensionally stable thermoplastic tubular articles
Inventor: BUTCHER PETER EDWIN
IPC: B29C71/02
Filed: 1983-04-22
Abstract: For heat-setting tubular articles (such as can bodies) of an at least partly biaxially oriented crystallisable polymer, preferably a saturated linear polyester such as polyethylene terephthalate, e.g. for thermally processable food containers, a tube (26) of the polymer is fitted over a mandrel (101) and clamped at its ends to the mandrel at a temperature belowthe glass transition temperature of the polymer. The tube is then heated, e.g. by inserting a heater (28) into the interior of the mandrel, above the temperature to which it is to be heat-set (at least 60°C above for PET) whereupon it shrinks into contact with the mandrel but is restrained from axial or further radial shrinkage. The tube and mandrel are cooled to below the heat-set temperature and the tube may then be cut by knives engaging in circumferential grooves (22) into can body sections. Contact between the tube and mandrel is released, e.g. forforcing compressed air out through small holes (16) in the mandrel surface to allow the tube and mandrel to be separated.Tubularbodies with one closed end can be heat-set on a mandrel with a correspondingly shaped end.

Title: Electrode contacts for high current circuit interruption
Inventor: FARRALL GEORGE ALBERT
IPC: H01H1/02
Filed: 1983-06-28
Abstract: Electrode contact materials exhibiting a high degree of arc stability, particularly at low arc currents, are employed in electrical circuit interruption devices, particularly vacuum interrupters. Solidified mixtures of mutually insoluble metals provide high arc stability, thus permitting arc interruption without the generation of excessively high voltage transients. Mixtures of copper and 1-92 wt.% vanadium have been found to be particularly effective for such purposes. Furthermore, the use of directionally solidified composite materials provides improved heat conduction and low resistance path characteristics. Other pairs of metal components disclosed are:-    Cu and Bi    Cu and Li    Cu and Pb    63-99% Al and Ti    Al and 1-82% Sb    80-99% Al and Cr    1-98% Al and Be Al and Bi  me

Title: Apparatus and method for monitoring machining conditions of a machine tool
Inventor: BUNGE GUNTER
IPC: B23Q17/09
Filed: 1984-05-17
Abstract: Apparatus and a method for monitoring the machining conditions of a machine tool by the continual sequential measurement of a plurality of physical magnitudes characterising the machining process, and the combination of abnormal values which are detected being evaluated to indicate a condition identifying a tool breakage or process irregularities. For this purpose the ultrasonic emission from the machining process, the main and the feed drive powers are measured and sequentially evaluated with respect to its deviation from a predetermined nominal range for its distribution. If the nominal range of the measured value distribution is exceeded a signal is emitted and stored. The simultaneous occurrence of signals from all three measured values is emitted as a tool breakage signal and the simultaneous occurrence of two signals leads to the emission of an alarm signal relating to process irregularities. <IMAGE>
