cotton and wool: situation and outlook report, february 1993

the 1992/93 u.s. cotton crop totaled an estimated 16.3 million bales, 8 percent below last season. upland production is estimated at 15.76 million bales and extra-long staple at 497,400 bales. harvested area in 1992 was 11.15 million acres, nearly 14 percent below last season. a doubling of the upland cotton acreage reduction program (arp..

mechanisation of finished product warehouses

in the cotton industry the finished product, after checking and coiling on reels, is transferred by a belt conveyor to the warehouse department and on to a special table where it is marked and wrapped in paper. the reels of textile are then loaded on to four-wheeled vehicles with two end plates, which are used for transfer to storage or t..

an electronic vision system for sorting cotton boll worm pupae by sex

the cotton boll worms heliothis zea and heliothis virescens are becoming increasingly resistant to insecticides. rather than using more powerful chemicals to control these pests, an environmentally safe biological control system is being developed this system, based on the mass release of sterile male insects, requires the sorting of larg..

from core to hex' computers in a test house situation

the new zealand wool testing authority operates eight objective measurement laboratories situated in each of new zealand's wool selling centres. a network of wang 2200mvp computers links the various laboratories and provides test result input, communications and printing facilities in the centre closest to where each client resides. the c..

down on the farm (farmplan microcomputer system)

at woolbeding farms a tastefully furnished office within a converted old barn controls the complete administration of five local farms totalling 1600 acres. the office uses a farmplan microcomputer system and nine software packages. the system comprises an apple ii 64k microcomputer and monitor, two 5-in. apple disc drives and an anadex d..

diffusion grown superconducting thick films of bi-(pb)-sr-ca-cu-o with zero resistance at 103 k

thick films of lead doped bi-sr-ca-cu-o have been grown with zero resistance above 103 k. the films were grown on nonsuperconducting precursor substrates. these substrates, which had the compositions srcacu/sub 4/o/sub 6/ and srcacu/sub 2/o/sub 4/ were coated by either sedimentation or silk printing with appropriate mixtures of bi/sub 2/o..

polymer thick film technology: an economical solution adds to conventional printed circuit board production

in polymer thick film technology (ptf), electrical conductors as well as passive elements are made by simple silkscreen printing of metal-filled pastes followed by hardening. this technology is useful for the production of rigid as well as flexible printed circuit boards. in the telecommunications industry, this process is completely new...

infrared dynamic scene generator using halftone reflectance images

an infrared dynamic scene generator (irdsg) was developed at ball aerospace systems division (basd) in order to test an integrated sensor/processor. using halftone images silkscreened on the surface of a mirror, the dsg presents to the sensor a replica of the inband radiances of a selected scene, taken from a digital database. the mirror ..

investigation of films of yba/sub 2/cu/sub 3/o/sub 7/ using rutherford backscattering spectrometry

rutherford backscattering spectrometry (rbs) has been applied to films of the high-temperature superconductor yba/sub 2/cu/sub 3/o/sub 7/. the films were prepared by rf and dc sputtering and silk-screen printing onto substrates of alumina, sapphire and magnesia. some of the samples were exposed to various heat treatments in order to promo..
