Title: Prepn. of (1,5)-di-aryl sulphonyl (1,2,5/3)-cyclohexane tetrols - intermediates for the prepn. of amino glucoside antibiotics
IPC: C07D317/72
Filed: 1975-07-22
Abstract: Cyclohexane diol derivatives of formula (I) are prepd. from 1L-1,2,5/3 cyclohexane tetrol (II) by treatment with an aryl sulphonyl chloride (III) at -5 to +5 degrees C. (where R = aryl sulphonyl). (I) are intermediates for the prepn. of synthetic aminoglycoside antibiotics as described in BE 825456. The method is much simpler to carry out on an industrial scale than the known method of making (I), and gives better yields (65-70% overall, as compared with 34%). The pref. cpds. (I) are those where R = tosyl or p-bromo benzene sulphonyl. The reaction is pref. effected in pyridine at 0 degrees C. In an example 2.93g (II) in 10 ml pyridine was treated at 0 degrees C with 9.5g (III, R = tosyl) to give 73% yield of (I, R = tosyl) m.pt.

Patent FR-2320007-A1 (FR)
IPC: H03M1/02
Filed: 1976-07-21
Abstract: In a coder/decoder which operates on a subscriber-individual basis using the iterative method, with an intermediate register (FF1...FF8) which can be controlled by a counter (Ct) and which has a digital-analog converter (DAC) connected downstream and a comparator (Cp), a partial time span for digital-analog conversion and a further partial time span for analog-digital conversion are defined within a pulse frame by means of different counter settings of the aforementioned counter (Ct). The same digital-analog converter (DAC) is used twice in succession for D/A and A/D conversion. The counter (Ct) can be synchronised from time slot to time slot by the digital signals which are to be converted. In addition, the counter (Ct) can be activated to control the conversion of analog signals even in the absence of digital signals. The operating feed voltage can be supplied to the coder/decoder and the associated subscriber station (Tn) simultaneously with the activation of the counter (Ct).

Abstract: An artificial leather is a combination material, with an outer layer of porous water-proof polyurethane bonded to a substrate of moisture-absorbent textile fibres, and an abrasion-resistant moisture-migrating textile e.g. a fleece or synthetic lining, the layers being bonded with an adhesive which is porous to moisture. Pref. the top layer is a porous water-proof hot-formed aliphatic polyurethane or light-fast aromatic polyurethane produced from 30% w/w in mixed solvent and water. with electrolytes to prevent emulsification and with a viscosity controller such as dimethyl-formamide or tetrahydro-furane. The mixt. is applied to a fibrous substrate, pref. a mixt. of strong fibres (e.g. polyester) plus (e.g.) viscose to ensure swelling, and dried. The other side is then treated with a dirt-repellent material e.g. acetate, polyamide etc. and calendared. Germicides and fungicides can be incorporated in the system. In porosity to moisture, imperviousness to water, mechanical strength and flexibility it is very similar to leather, and can be given leather-like appearance. It is produced in any colour, and is handled and processed like leather.
Patent FR-2339960-A1 (FR)
IPC: H03H9/19
Filed: 1977-01-27
Abstract: A piezoelectric vibrator element is shaped by photo-etching techniques from a quartz crystal wafer. Film electrodes and masses for frequency adjustment are applied by first depositing a layer of chromium and then a layer of gold on the element by vacuum depositing or sputtering. The element is then kept in a high vacuum of at least 10-5 torr and at a high temperature of 300 DEG  C to fix the depositions on the element and eliminate distortion. To adjust the frequency, a portion of the metal mass is removed by a laser beam, after which the element is kept in a high vacuum at high temperature to affix securely to the element any bits of metal that may have condensed during the removing step. .

Title: Controlled nuclear fusion of atomic particles - using appts. incorporating concentric spheres with intense radial electrostatic field between them concentrating particles at point
IPC: H05H1/03
Filed: 1977-01-28
Abstract: An appts. for bringing about nuclear fusion of atomic particles, e.g. nuclei of hydrogen or its isotopes, comprises a spherical enclosure in which is a second sphere, concentric with the first. The enclosure has tubular elements over its surface. The axes of these elements are on radii of the concentric spheres and they open at one end into the enclosure. The other end carries a set of electrodes. The surface of the second sphere has a cellular structure so that particles entering the enclosure can pass through into it. Each sphere carries metallic structures connected to the two poles of an electrical potential source so as to create between the spheres as electrostatic field which can communicate a large kinetic energy to the particles. A source of electrons is placed in the second sphere near its centre. A second electrical potential is established inside the second sphere between it and the source of electrons. The resulting electrostatic field retains the electrons inside the second sphere. The appts. allows a very great density of atomic nuclei of high kinetic energy to be obtd. by the concentrating of the nuclei at a point in space instead of a closed line as in the case of electromagnetic devices at present tried.

Title: Diesel engine fuel filter - has flow controlled by baffle system with upper skirt with central aperture, lower conical portion and radial ribs
IPC: B01D35/30
Filed: 1977-04-08
Abstract: The diesel fuel filter includes a main body portion within which is contained the fuel filter element.
