Title: Isobutylene recovery from 4C hydrocarbon fractions - by intermediate conversion to tert. butanol and dehydration of the alcohol
IPC: C07C1/24
Filed: 1974-11-18
Abstract: Isobutylene is recovered from 4C hydrocarbon fractions by (1) heating the fraction with water in a mol. ratio 1:5 to 1:20 at 70-110 degrees C and 16-23 atmos. in the presence of a catalyst and a polar solvent present in amts. of 10-70% on wt. of water, to form a reaction mixt. contg. tert. butanol and water; (2) recovering the tert, butanol as an aq. soln. and (3) subjecting the soln. to catalytic dehydration of the tert. butanol at 80-110 degrees C under a pressure of >3 atmos. whereby the catalyst used in stages (1) and (3) is a formed ion exchange catalyst consisting of a 1-4:1-2 mixt. of a sulphonated styrene-divinyl benzene copolymer and a sulphonated thermoplastic matl. The catalyst has high activity (1.5-2 fold that of sulphonic acid exchangers), good heat resistance (4000-4500 hrs working life at 85-100 degrees C) and gives improved process output cf. known sulphonic acid exchanger catalysts.

IPC: C23C16/44
Filed: 1975-11-13
Abstract: A method is provided for growing highly oriented compound thin films on a substrate by subjecting the substrate to the vapor of a first single element which can react with the surface at a temperature sufficiently high for the reaction to occur which forms a single atomic layer of the first single element on the surface and then subjecting the thus formed surface with a first single element atomic layer thereon to the vapor of a second single element which can react with the first single element at a temperature sufficiently high for the reaction to occur so that a single atomic layer of the second single element is formed on the surface bound to the first single element. This procedure can then be repeated alternately subjecting the surface to the vapors of the first single element then to the second single element, etc. until the compound film reaches a desired thickness. There is further provided an apparatus for carrying out this method comprising a vacuum chamber with evacuating means, a support for supporting a substrate, sources for at least two vapors of two different single elements and operating means for providing on the substrate first a single atomic layer of one of the elements, and then a single atomic layer of the other of the elements.

Patent NL-8302075-A (NL)
IPC: G11B5/52
Filed: 1983-06-10
Abstract: In a helical scan video recorder in which the magnetic heads are arranged on bimorph piezoelectric actuators it may be desirable, in order to counteract depolarization of the piezo-electric elements, to bias these elements. This is possible without the use of additional slip rings if the electrode to which the drive voltage is applied is connected, via a diode, to the electrode to which the bias is applied and the bias is applied, alternately with the drive voltage, at instants at which the associated magnetic head is not used. If the (lower) drive voltage is applied the diode is cut off and the bias is isolated from the drive.

Title: Convergent solar energy collector - presents planes of reflectors constantly at right angles to incident solar radiation
IPC: F24S23/00
Filed: 1976-09-24
Abstract: A convergent device for collecting and using solar energy comprises an arrangement of mirrors, fixed in its geometry, but capable of being oriented in all directions. The mirrors are stabilised according to angles calculated to give a convergence of the incident solar radiation. The device precisely follows the apparent motion of the sun and presentsits surface place constantly at right angles to the solar radiation. The stable position of each reflector is calculated to receive the radiation in such a way that the angle of reflection equals the angle of incidence. The reflected radiation becomes incidental radiation on the surface of a counter-reflector which reflects it towards the focus of convergence at a point beneath the base of the device, around a point on the axis perpendicular to its plane. The stable arrangement of the reflectors and the counter-reflectors is the same on all the secant planes. The geometrical arrangement of the plan of the device is arbitrary and may be a polygon or a circle. Appts. gives a yield, relatively to the amt. of surface exposed, much higher than those of existing devices. The only limiting factor is the amount of sunshine of the locality and the device can be installed anywhere provided there is sufficient sunshine, whether there is wind or not and irrespective of the terrain or location (on roof, etc).
