stress relief printed circuit wiring

a technique is described for providing stress relief in printed wiring patterns on printed circuit cards for compensating for variances in thermal expansion and contraction between components and the card. in the past stress has been concentrated in the solder connection. on compliant surface cards stress has been transferred to the print..

error recovery for robotic component insertion

the method sets forth searching and finding insertion locations, thereby increasing the reliability of robot assembly of pc (printed circuit) cards. three pieces of hardware are required these are a vacuum chuck, a binary vacuum sensor, and a block of steel in which chamfered holes have been drilled to receive and straighten component lea

widening and strengthening of existing pavements in black cotton soil areas and investigation of failures

the paper presents the procedures followed for investigations, design and construction of widening and strenghening of existing pavements with the use of sophisticated machinery in a national highway section passing through black cotton soil area. failures of pavements in certain stretches of the strengthened stretches have also been repo..

cotton dust characterization: a comparison of sonically separated fine dust ( $less than$ 20 $mu$ m) with respirable (vertical elutriator) dusts

based on comparison of properties of the inorganic composition of various cotton dusts, this paper demonstrates that cotton dusts $less than$ 20 $mu$ m in diameter separated from card room condenser trash material are very similar chemically to dusts collected in that same environment by a vertical elutriator cotton dust sampler. a method..

pressure maintenance by in-situ combustion, west heidelberg unit, jasper county, mississippi

the west heidelberg cotton valley sands unit in jasper county, miss, is the location of what is probably the world's deepest in-situ combustion project. the cotton valley sands are of jurassic age, occurring at an average depth of 11,400 ft (3475 m). fourteen sands are identifiable in the cotton valley, but only eight are productive of th..

drip irrigation of cotton with saline-sodic water

a two-year study was conducted in the negev region of israel, using the drip method, to determine the effect of four levels of water quality in combination with three soil amendment treatments (gypsum spread on the soil surface along the drip laterals after planting, injection of h//2so//4 into the water during each irrigation, and a cont..

utilisation de l'huile vegetale dans un moteur diesel a chambre de turbulence. $left bracket$ use of vegetable oil in a diesel engine with swirl chamber $right bracket$

a 50 - hrs operation test of a diesel engine with a turbulence chamber fed with cotton oil demonstrates the feasibility of the substitution of diesel oil by cotton oil. without any modification of the engine settings, the performances of the cotton oil engine are lightly decreased. this type of engine seems better adapted to vegetable oil..

seasonal spectral characteristics of four crop canopy architectures

spectral and phytomass measurements were taken from cotton, soybeans, sunflowers, and guar throughout a growing season. a ground-based radiometer sensed reflected electromagnetic radiation in seven wavelength intervals (wli's) that included the thematic mapper bands. the seasonal spectral profiles for each crop were similar to the pattern..

influence of four cover conditions in cotton production

influence of three cover crops (wheat, vetch, and crimson clover) and no-cover condition combined with three planting techniques and two cover kill schemes on cotton performance is investigated over a three year period. plant dynamics and soil environment parameters are discussed. the influence of these factors is examined and some observ..
