Patent NL-292758-A (NL)
IPC: C07F5/06
Filed: 1963-05-15
Abstract: Alkyl aluminium compounds are prepared by treating a non-a -olefin (as defined) with a low molecular weight alkyl aluminium compound (as defined) using as catalyst a compound of Groups IV(a), V(a), VI(a) (i.e. Ti, V and Cr groups).  The non-a -olefin is defined as an olefinic hydrocarbon or mixtures thereof wherein at least 40% of the molecules have a non-terminal olefinic double bond.  The mixture may contain up to 50 mol. per cent of olefins of chain length equal to or less than that of one or more of the alkyl groups of the aluminium compound.  The alkyl aluminium compound is defined as having alkyl groups with fewer carbon atoms than the non-a -olefin employed in the process and may have one or two H atoms attached directly to aluminium.  The catalyst may be a halide preferably the chloride and/or a compound having an oxygen atom linking the metal with a carbon atom.  More particularly the catalyst may be an alcoholate, a chelate, or a phenolate e.g. methylates, ethylates, propylates, isopropylates, phenolates, cresolates, acetylacetonates, salicylates, benzoylacetonates, 2-furoylacetonates; of Ti, Zr, V, U, Cr, Th, W, Ta, or Nb.  The low molecular weight alkyl aluminium compound is preferably tri-isobutyl aluminium but may also be tri-ethyl, propyl or n-butyl aluminium, di-isobutyl aluminium chloride or diethyl aluminium hydride, the preferred compounds having alkyl groups containing at the most 4 C atoms. The non-a -olefins suitable for the process are but-2-ene, pent-2-ene, hex-3-ene, oct - 2,3 or 4 - ene, dec - 5 - ene, tridec-6-ene but preferably having at least 6 C atoms. The non-a -olefin may be obtained (a) by dehydration of an alcohol or mixture of alcohols; (b) by thermal or catalytic cracking of hydrocarbon feedstocks (c) from the residue left after removal of a -olefins by polymerizing with a Ziegler catalyst.  The non-a -olefin and the low molecular weight alkyl aluminium compound may be used in molar ratio 1.5: 1 to 10: 1 and the catalyst in amount 0.05 to 10% but preferably 0.5 to 5% mol.  The reaction temperature may be 50-250 DEG  C. but preferably 100-150 DEG  C. whilst preferred reaction conditions are 0.1 to 2% mol. of catalyst at a temperature of 150-200 DEG  C. In examples 1-3, 1-octanol is dehydrated with 100% phosphoric acid and the octenes mixed with tri-isobutyl aluminium. TiCl4 was added to the mixture, which was then heated and the isobutene produced collected in a cold tap.  In other examples various octenes are used whilst examples 15-53 relate to various catalysts used in processes involving octenes.  Primary alcohols are made by the oxidation of the alkyl aluminium compound prepared as above, to form an aluminium alcoholate followed by hydrolysis of the alcoholate.  In an example the reaction product from a mixture of non-a -octenes is oxidized by bubbling in air and then hydrolyzing with 10% hydrochloric acid, to give 1-octanol after separation and purification. The preparation of 1-octanol is exemplified using various catalysts and starting materials.  Specifications 827,901, 941,016 and 993,666 are referred to.

Title: Modified corona discharge system - giving improved charge retention on photoconducting substrates
IPC: B29C59/12
Filed: 1973-09-27
Abstract: Charge is formed on a photo-conducting surface, by maintaining a p.d. producing a corona discharge between a corona-effect discharge electrode and a base electrode, interposing a photo-conducting surface, on which the charge is to be formed, near the base electrode and onto which a current of gas is simultaneously directed in the opposite direction to the flow of charged particles which tend to be driven from the region where the charge accumulates, in order to pentrate the gas layer at the interface to increase the charge retention and formation of secondary ions on the charge-accumulation surface. The gas is pref. monatomic or is O2, N2 or CO2.

Title: Mixed barium-strontium-calcium oxide cathode coating material - contg. much less barium and less strontium oxide, reducing volatility
IPC: H01J1/14
Filed: 1975-01-15
Abstract: The cathode oxide coating material contains 1-20 mole % BaO, 30-50 mole % SrO and 40-65 mole % CaO. The coated anodes are used e.g. in amplifier and transmitting tubes. Volatilisation of the oxide coating material is greatly reduced, whilst a high emissivity is retained, i.e. a low work function is ensured, by the use of more CaO, much less BaO and less SrO than usual. The volatility is 0.08-0.2 units at 1050K, i.e. 5-12 times less than usual, whilst the work function remains at 1.50-1.65 eV. The drop in emission is only 20-35% in 5000 h operation (cf. ca 50% for the usual material contg. equimolar amts. of BaO and SrO and up to 13 mole % CaO).

Title: Adjustable delivery liq. valve for medical and laboratory use - is inexpensive, easily regulated and gives precise flow control
IPC: F16K47/06
Filed: 1976-10-08
Abstract: An adjustable delivery valve suitable for inserting in a flexible pipe line for a comparatively small flow rate, e.g. to carry a glucose feed to a medical patient is described liq. passes through the valve ia an annular space between a cylindrical, inlet core and a coaxial, outlet sleeve made of flexible material. The sleeve can be deformed pref. elastically, by an external clamping ferrule, so that the sleeve is held against the core all around its circumference. The external surface of the core is fluted with a valve channel, which extends axially and has a changing cross sectional area throughout its length. Delivery can be adjusted by moving the ferrule axially along the sleeve to clamp it onto a different cross-section of value channel which thus becomes the controlling factor of the rate of flow through the valve. Adjustable delivery, small output valve esp. for medical and laboratory applications, e.g. administering to a patient a controlled flow of a liq. such as blood, saline soln. glucose, water etc. Inexpensive construction, ease of adjustment and precise control of flow rate.

Title: Multilayer circuit board with integral flexible appendages - uses array of flexible circuit layers bonded between rigid layers having suitable electrical connections
IPC: H05K3/00
Filed: 1977-05-31
Abstract: All the layers are substantially larger than the size the finished circuit board is to be and selectively bonded and slotted in pre-selected locations, and maintained in this over-sized condition throughout the procedure in which holes for interconnections are drilled, and plated through with conductive material. Only after the plating procedure has been completed are the portions of the upper and lower rigid layers removed from locations above and below the appendage portions, thus allowing them to attain the desired, flexible condition. By keeping the rigid layers intact, the assemblage is maintained rigid during the plating, thereby avoiding work hardening of the flexible portions even without tools for restraining the flexible portions.
