Title: Transfer of data held in bubble domain memory - using magnetic tape transport directly under memory plate (NL070976)
IPC: G11B5/49
Filed: 1975-03-03
Abstract: A transfer system allows information entered into a bubble domain memory to be transferred onto magnetic tape. The video information is entered over an isolating stage (5) and an encoder (C) controlling a generator (G) coupled to the shift register bubble domain memory contained in a plate (1). The serially generated information is converted in this way to parallel form. A number of memories may be stacked side-by-side to provides storage of input words. When the registers are full it is required to execute a transfer of the contents onto magnetic tape (4), by generating the correct field strength using a pulse generator (P) coupled to a common connecting line (7).

Title: Highly stable quartz-crystal tuning fork oscillator - has arms trimmed to minimise vibrational energy transfer to base
IPC: H03H9/09
Filed: 1975-03-20
Abstract: The quartz-crystal tuning-fork oscillator consists of two vibrating arms with a common support, the whole having a U-shape. The bottom of the U is bonded to a base with terminal pins for connections, and the amount of energy transferred to the base by the arms vibrating is measured. This stray or lost energy is then reduced to a minimum by trimming the sizes of the arms as many times as necessary. The electrodes on the U's arms can be connected by an electrically-conducting adhesive to the contact pins on the base instead of using connecting wires. The oscillating element has high frequency stability over long periods of time.

The buoyant chamber is a closed shell filled with closed-cell foam to prevent access of water in the case of damage to the sheel. To give maximum support to the shaft the buoyant chamber is of slightly tapering external form and truncated as its aft end.
Patent NL-7507241-A (NL)
IPC: F04D29/38
Filed: 1975-06-18
Abstract: A fan for moving a gaseous fluid, e.g., air, is described in which the high audible frequency noise resulting from the phenomenon occurring at the trailing edges of the blades, known as vortex shedding, is reduced. This is accomplished by notching an edge of each of the blades so that the pattern of vortices leaving the blade, which causes the noise, is disturbed and a turbulence condition engendered. The turbulence distributes the pressure fluctuations resulting from movement of the blades through the fluid over a relatively broad band of frequencies and reduces the annoying noise frequencies. Various notch configurations are disclosed.

Title: Pulping of lignocellulose with catalyst - comprising aq. alcohol and alkaline earth metal salts gives improved pulping efficiency
IPC: C13K1/02
Filed: 1982-01-22
Abstract: Fragmented lignocellulosic material is cooked with an aq. (m)ethyl alcohol (of 80-98% alcohol by vol.) contg. a dissolved alkaline earth metal salt. This salt can be a chloride or nitrate of magnesium, calcium or barium, or magnesium sulphate or a soluble mixture of these salts. The amt. of the salt is 0.001 to 0.5 molar. Opt. an acid reacting substance of less than 0.005 normal is also added. The mixt. is cooked for not more than two hours at above 130 deg.C, the amt. of cooking liquor being at least 4 pts. wt./pt. lignocellulosic material. The fibres are sepd. off and the spent cooking liquor separated into solvent, lignin and sugars. Method is used for pulping lignocellulosic materials with alkaline earth metal salts in aqueous alcohol to give efficient pulping and recovery of lignin in a more convenient form i.e. as a powder. The combination of high alcohol content together with an alkaline earth metal salt and an added acidic substance gives improved efficiency compared to prior art solvent pulping methods.

Title: Method for preparing silicon dioxide particles and use thereof
IPC: C03C1/00
Filed: 1988-08-27
Abstract: The present invention relates to a method for preparing equiaxial, preferably spherical silicon dioxide particles having a surface free from hydroxyl groups, a density of more than 1.9 g/cm3, a particle size of preferably more than 50μm, and a controlled narrow size distribution, by allowing a siliconhalogenide, preferably silicon tetrachloride, to react with droplets of water which are emulsified in a liquid nonmiscible with water. The reaction is preferably carried out with droplets of water in a frozen state. By using this method it is possible for silicon dioxide particles to be conditioned, in terms of particle size and particle size distribution, in a very simple manner in a single-stage process.
