Markings cable

Small size, ruggedness, simple cabling and the ability to operate the equipment under adverse conditions in the field has also been design goals. The system should also conform with the regulations necessary for the CE-marking (i. e. standards and directives for EMC, Electrical Safety and Machine Safety). 

Dip Stick Indicators. Visual level indication can be obtained by dropping a weighted cable or rigid dip stick into the media until it reaches the bottom of the vessel. Graduations are marked on the cable or stick. Upon retrieval the operator looks for the point of dry vs wet indicating the depth of the media. This method of level indication is useful in ambient/atmospheric appHcations in nonha2ardous environments. It is not recommended for other appHcations. Measurements are accurate only to the extent of the skill of the operator. 

From this table it will be noted that in terms of the mechanical and thermal properties quoted the copolymers are marginally inferior to the homopolymers. They do, however, show a marked improvement in resistance to environmental stress cracking. It has also been shown that the resistance to thermal stress cracking and to creep are better than with the homopolymer.This has led to widespread use in detergent bottles, pipes, monofilaments and cables. 

The variation in potential between the sheath of a lead-covered cable lying parallel to a d.c. railway system and a reference electrode placed close to the cable is shown in Fig. 10.36. The shut-down potential of the cable in this test was -570 mV [Cu/CuS04(sat.)]. There is a marked positive change in... 

Check all wiring and electrical controls, for correct circuitry, security of terminals, continuity, insulation, compliance with safety regulations such as lEE, marking of terminals and cables, etc. Check action of all controls as far as may be possible without running any item [63]. 

But April 20 marked the beginning of a concrete plan by which private citizens could "buy" the Jews out of Germany. The first cable received five months before, the second cable buried for two months — and between the two cables apparently a three-month silence from Bern that didn t make any sense. 

The principle embodied in Mark 29 Anti-torpedo Device was as follows Two explosive streamers and a third streamer contg audio pickups sensitive to vibrations from the torpedo were to be trailed by a faired (joined so that external surfaces blend smoothly) cable attached to a paravane (See Note). When a torpedo passed over or under the detector streamer, one of the explosive streamers would be fired automatically to destroy the torpedo. The 2nd streamer would then be thrown automatically into the firing circle in readiness for a 2nd attack (Ref 2)...

The simplest of the formats used to transfer data into word processing applications is the ASCII (.ASC). ASCII is a standard set of 128 binary codes used by all computers to represent all the characters presented on the normal or shifted keyboard plus control codes, originally intended for use on teletypewriters. These code allow us to display lower case leters, capital letters, numbers, and punctuation marks, but formatting codes for underline, boldface, and italics are not included in ASCII, and are removed in converting formats. ASCII files have space-separated code and can be sent out over a modem or a serial cable to another computer and applications importing ASCII code.

One simple vivid example of poor communication in maintenance occurred after the plant staff marked the location of an underground electrical bus with a series of flags on the surface. No one discussed the job with the backhoe operator, so when he saw the flags, the hoe operator assumed that the flags indicated the location of the path to be dug. He severed the sub-surface electrical cables and a large portion of the chemical plant facility was blacked out. The report failed to mention the fate of the backhoe operator. [1]... 

Depth profiles in observation wells, or nonpumped wells, are conducted by lowering sensors into the well. The depth is usually read from markings on the electrical cable. The lowering of sensors into the well agitates the water and mixes the water column in the well. For this reason,... 

U = this mark indicates that the certificate is a component certificate for electrical equipment which cannot operate on its own (e.g. cable entries for enclosures in increased safety - e -). 

The General requirements cover apparatus grouping and temperature classification, constructional requirements for enclosures and fasteners, connection facilities and terminal compartments, cable entries and supplementary requirements for rotating electrical machines, switchgear, plugs and sockets and luminaires. A third part of the standards cover type verifications and tests as well as marking requirements. 

Higher temperatures at these points ask for installation with special heat-resistant cables (e.g. with silicon-based insulating material). In this case, the apparatus shall be marked with an X for this special condition. 

Standards do not ask for a defined way of marking. If a colour is used, however, it shall be light blue. This is the marking used for the most part in practice light blue coloured cables, terminals, markings of connections of apparatus etc. 

Batfish and UOR Mark 1, and 10 m/s for UOR Mark 2). Below 5 m/s, fixed-attitude wings (span, 0.75 m) are fitted to provide increased hydrodynamic lift for long cable lengths and heavy instrumentation loads up to 150 kg. Fitting produces an undulation amplitude of 80 m at 4 m/s with as little as 180 m of unfaired 6.5-mm diameter cable in water. 

Figure 2b. Computer-plotted undulation profile (2.5-68 m) for a UOR Mark 2 tow at 5.5 m/s with 200-m, 6-mm outside diameter (OD) cable outboard of 200-m, 8-mm OD cable (about 300 m of cable in water). Taken from F.R.V. Cirolana, Celtic Sea, May 1981.
