Abstract: Un appareil d'alimentation en énergie HF comprend: une source commutable d'énergie (12) ayant une unité de commande (122) qui produit des signaux de commande de fréquence prédéterminée injectés de façon intermittente et qui peut être réglée arbitrairement pendant que les signaux de commande sont injectés en continu. Une unité de commutation (121) reçoit un courant continu et est mise sous ou hors tension en réponse aux signaux de commande, de façon à produire un courant continu sous forme d'impulsions intermittentes. Une unité de redressement/filtrage (123) redresse et filtre la sortie de l'unité de commutation (121) de façon à produire un courant continu. Un onduleur HF (13) reçoit le courant continu de la source commutable d'énergie (12) et produit un courant HF. L'appareil d'alimentation en énergie HF convient pour générer un faisceau laser à des fins de commande d'impulsions.

IPC: C08K9/04
Filed: 1988-03-03
Granted: 1992-06-17
Abstract: Hydroxyfunctional carboxamide compounds of formula I    <IMAGE>  (I) are included in thixotropic formulations containing highly disperse silica as a thickening or thixotroping component in order to activate the silica or enhance its effect, to amerliorate any tendency of the silica to settle and/or to prevent weakening of the thixotroping effect of SiO2 in formulations which themselves form relatively strong hydrogen bonds. The compounds of formula I may be added to silica-containing thixotropic liquid formulations to improve the thixotropy, or highly disperse silica may be coated with such compounds for later incorporation into liquid systems to render them thixotropic.

Title: Method for fluxless oven soldering
IPC: B23K35/22
Filed: 1988-07-04
Granted: 1991-03-20
Abstract: A method is described which is suitable for soldering components (B) in optical communications engineering, electronics and micromechanics to metallic substrates (T) and at the same time dispenses with the use of solder preforms, which are exceptionally difficult to manipulate, but without having to resort to soldering agents which contain flux. The conventional use of solder preforms is replaced by the use of a paste (P) which constitutes a mixture of a metal powder (Me) and a binding agent (Bi), the binding agent only being essential for handling the paste and being removed from the paste (P) by a vacuum (V) before the actual soldering process. A method of this type is used in micromechanics, e.g. in order to fasten a planar piezo-head to a nickel foil by soft soldering. <IMAGE>

Patent EP-0300647-B1 (EP)
IPC: G01M3/28
Filed: 1988-07-07
Granted: 1993-09-15
Abstract: A technique for detecting faults, blockages or holes, in a duct(6). A burst of compressed gas is injected into the duct and the decay of the pressure pulse monitored by a transducer at the gas burst launch end of the duct. A reference decay pressure that would be expected for a perfect duct is generated and the monitored decay is compared with the reference decay for deviation. A perforated duct exhibits greater pressure decay and a blocked duct less pressure decay than a perfect duct. The time occurrence of the deviation indicates the location of the fault. The signal level indicative of the pressure after a predetermined interval may also be used to measure the air friction or blowability within the duct.

Abstract: Coded text is converted to phonetic data to drive a synthesis filter. Accent data are also obtained to derive a pitch contour for a variable pitch excitation source. Recognition of the beginning of a paragraph causes a pitch contour of higher pitch than the pitch at a later part of the paragraph. The initial pitch falls following each subgroup into which phrases are divided. In another aspect of the invention, accents within a phrase are assigned pitch values which are high for the first accent, less high for the last; and the remainder alternate between higher and lower lesser values.

Abstract: PCT No. PCT/DE88/00329 Sec. 371 Date Aug. 24, 1989 Sec. 102(e) Date Aug. 24, 1989 PCT Filed Jun. 4, 1988 PCT Pub. No. WO88/09974 PCT Pub. Date Dec. 15, 1988.In a method for determining a route between a starting point and a destination which are located on a digitally memorized road map, the problem is to perform the necessary calculations for determining the route within a short time, even for extensive road systems. Otherwise, the results could arrive too late and could no longer lend the driver any aid in making a decision. The object is attained by dividing the road map into at least two levels of different grid density and regional size and storing it in memory. A plurality of smaller subregions of fine grid density are assigned to the lower level, and one or more larger subregions of coarser grid density are assigned to the higher level. Beginning with the lower level of the road map, a possible route is then studied; if the results are negative, a transition is made to the next-higher level, until a positive result is attained. Then the route is plotted within whatever level a positive result was attained in, for instance in the same level or back and forth between the levels.

Title: Optical fibre coupler and method of making such a coupler
IPC: C03B23/07
Filed: 1989-03-10
Granted: 1992-09-23
Abstract: An optical fiber coupler is formed by providing a glass tube (10) having a longitudinal aperture (12). Two contiguous carbon tubes (14,15) are disposed within the longitudinal aperture which is thereafter collapsed thereon. A glass capillary tube (30) is formed by removing the carbon tubes. The tube can be stretched to form a precision capillary tube which is severed into coupler-length tubes (44). Two optical fibers (52,53), which are shorter in length than the aperture (46) of a coupler-length tube (44), are centered in that aperture. The midregion (59) of the resultant assembly is heated and collapsed about the central portions of the fibers. The central region of the resultant coupler preform is heated and drawn to reduce the diameter thereof. The end regions (77,78) of the aperture, which are not diminished in size by the aforementioned processing, function as receptacles into which optical fibers can be inserted to make connection to the coupler

Abstract: A method of packaging a beverage and a package structure has a cylindrical tube 1 over an end 3 of which is located a partition wall 2 having a restricted orifice 6. A closure wall 7 is located over the partition wall 2 and both walls are sealed, for example by crimping, to the rim of the tube 1. A primary chamber 4 is formed within the tube and a secondary chamber 8 is formed between the partition wall 2 and closure wall 7 which chambers communicate through the orifice 6. Chamber 4 is charged with beverage 11 containing gas in solution and sealed with an end wall 12 crimped to the rim 9 of the tube 1. Prior to sealing the chamber 9 is dosed with liquid nitrogen or carbon dioxide so that headspace 13 in that chamber is pressurised. The package adjusts to a state of equilibrium in which beverage flows into the secondary chamber 8 to form a headspace 14 therein. Upon opening of the package with a pull tag 15 a pressure differential between the headspace 14 and 13 causes beverage and/or gas in the chamber 8 to be ejected through the orifice 6 into the beverage 11 and thereby gas in solution in the beverage to be liberated and form, or assist in the formation of, a head of froth on the beverage.
