Title: Photoconductive selenium film target for image pick=up tube - has layered construction with addn. of tellurium and arsenic in non-homogeneous distribution to give improved long term performance
IPC: H01J29/45
Filed: 1976-09-30
Abstract: Photoconductive film comprises (a) a first layer contg. selenium together with tellurium and elements which can form deep levels in selenium, in an average concn. of =10 atom %; (b) a second layer contg. Se to which Te is added with a continuous distribution of concn. with a peak value of >=15 atom% %. Film further comprises (c) a third layer contg. Se to which elements which can form deep levels in Se are added with a continuous distribution of concn. with a peak value of >=15 atom %; and (d) a fourth layer contg. Se to which Te and elements which can form deep levels in selenium are added, in an average concn. of =10 atom %. Pref. the thickness of the layers (a), (b) and (c) are >100 angstroms, 200-5000 angstroms, and 500-300 angstroms respectively. The elements which can form deep levels in Se are e.g. As, Sb, Bi, Si and Ge. The concn. of elements added to the third layer is pref. greatest at the interface with the second layer, and falls gradually towards the interface with the fourth layer. The films are built up e.g. by successive deposition of layers is not >100 angstroms thick to give the required concn. distribution of the elements. These layers can be formed e.g. by stagewise vaporisation of the respective materials. The films are esp., useful as photoconductive targets in image pick-up tubes with rectifying contact layer. Variations in signal strength and the retained image effect normally obtd. when the same object is exposed continuously are eliminated.

Title: Fusible interlining mfr. - using an electrical field to charge the fabric for electrostatic adhesive particle application
IPC: D06M10/00
Filed: 1977-09-28
Abstract: In the mfr. of a fusible interlining, the carrier material is passed through an electrical field formed between an open vessel for the adhesive to be applied in particles and electrical conductor. The adhesive is drawn from the vessel by the electrostatic charge on the material to form an adhesive application on one side. The treated material is heated for the applied adhesive particles to be bonded and melted into place. The process allows a fusible interlining to be made from a variety of fabric types and a range of different fibres.
Patent NL-7809661-A (NL)
Title: Drinking water prepn. from sea water by membrane-filtration - in which the sea water is fed directly into first stage filter without chemical pretreatment
Filed: 1978-09-22
Abstract: Drinking water is produced from seawater by means of membrane filtration in which the permeate from a first membrane filter unit is fed into the second membrane filter, the permeate from the second filter having a salt concn. less than that tolerated for drinking water. The seawater is fed directly into the first membrane filter via a coarse filter whose function is to remove large objects which might damage the equipment. The arrangement is pref. such that the salt concn. in the permeate from the first stage is 60% of that in the seawater itself. The pref. conditions for the filtration steps are 20-28 atmospheres for the second stage, 40-45 atmospheres for the first stage and surface area in the filter to concn. volume ratios of 100 m2/m3 in the first membrane and 10-50 m2/m3 in the second filter. Feeding the seawater direct into the first filter eliminates the traditional chemical pretreatment stage thereby reducing the overall size of the installation.

Title: Process for the production of alpha-6-deoxytetracyclines and process for preparing a useful hydrogenation catalyst for this purpose
Inventor: KHANNA JAGMOHAN
IPC: B01J27/00
Filed: 1990-01-05
Abstract: This invention relates to a process for the production of alpha-6-deoxytetracyclines and a process for the preparation of a hydrogenation catalyst which is useful for this purpose. The catalyst in question has the formula: <IMAGE> where Ph is phenyl, R is hydrogen or C1-C4 alkyl and X is chlorine, bromine or iodine. This compound is particularly useful as a homogeneous hydrogenation catalyst in the production of alpha-6- deoxytetracyclines, particularly the antibiotic doxicycline.
