Patent EP-0251152-A1 (EP)
Inventor: MEIER GERD E A DR
IPC: B08B3/10
Filed: 1987-06-23
Abstract: The device has a pipeline (5) which has a valve with a valve body (3) at one end which can be moved from a starting position into an operating position, and an actuating device (4) acting on the valve body (3). The device is connected at a distance from this end of the pipeline to a liquid feed (2). To produce a high-pressure pulsed liquid jet without a separate high-pressure device, the liquid is suddenly retarded by the valve body (3) reaching its operating position to produce a liquid pressure surge at the end of the pipeline containing the valve. At least one jet opening (12) of smaller cross section than the pipeline cross section opens at the end of the pipeline having the valve and, at least in the operating position of the valve body (3) it is open in order to deliver the pulsed jet. Preferably, a passage opening (7) which is closed in the operating position of the valve body and is of greater cross section than the jet opening (12) is controlled by the valve body (3) and the end of the pipeline remote from the valve opens into an acoustically soft device (1) which reflects the pressure wave produced during the liquid pressure surge as a reducing wave. In addition, the jet opening (12) is preferably blocked off in the starting position of the valve body (3). <IMAGE>

Abstract: An implement (12) is connected through its towing tongue (25) to a tractor (10) by way of an upright transmission (43) and a coupler which comprises a hitch bracket (28) and hitch adapter (80). In order to avoid the transmission (43) having to withstand the towing forces, the transmis­sion (43) is supported entirely by the tongue (25), and the coupler (28, 80) is connected to the tractor (10) and tongue (25) exclusively of the transmission (43). In this way the towing forces by-pass the transmission (43) and are transmitted by the coupler (28, 80). This means that the transmission (43) can be less robust and therefore can be made cheaper. 
     The transmission (43) can comprise two identical right ang­le gear boxes (46, 52) of which the lower box (52) is turned to maintain alignment by a steering arm (102) connected to the hitch adapter (80) as the tractor (10) turns.

Abstract: When using containers of agricultural chemi­cals, such as herbicides, pesticides and the like, it is desirable to transfer the contents to the sprayer tank by pump means rather than physically lifting the container to the tank inlet and then pouring the contents manually into the tank. It is also essential to rinse out the container prior to disposing of same as most of the chemicals used are concentrated and can cause environ­mental damage if the majority of the contents are not removed prior to disposal. The present device allows the operator to transfer the chemical to the tank (10) by means of a pump (12) and then wash or rinse out the container with water which is then also transferred to the sprayer tank (10). A control valve portion (24) connects to a concentric tube assembly (23) which includes a container piercer (57) on the lower end thereof. The valve means (25A, 26A) may be manipulated to pump the chemical from the container to the sprayer tank (10) and to then pump water into the container and spray the interior thereof in order to thoroughly rinse same. The valves are then changed to pump the diluted chemicals into the sprayer tank (10). A flexible shroud (47) surrounds the   conduits (30, 31) and is spring-loaded to retain same in contact around the area of the container in which the piercer (57) engages, in order to prevent concentrated chemicals from splashing the operator.

Abstract: An integrated circuit probe station comprises a table having a substantially planar upper surface, an IC probe positioned over the table in spaced relationship with the upper surface of the table, a chuck carrier, and a chuck. The chuck carrier has a substantially planar lower surface that is positioned in confronting relationship with the upper surface of the table, and a film of viscous material is interposed between the upper surface of the table and the lower surface of the chuck carrier, whereby the chuck carrier may be moved manually relative to the table in horizontal directions while resting on the table. The chuck is carried on the chuck carrier and is movable vertically relative to the chuck carrier. A mechanical prime mover is effective between the chuck carrier and the chuck for bringing about vertical movement of the chuck relative to the chuck carrier.

Abstract: A method and apparatus for controlling the polarisation of an optical signal has many applications, including in coherent systems, eg heterodyne detectors. 
     Four birefringent elements (19, 21, 23, 25) in series are arranged to rotate the state of polarisation (SOP) alternately about orthogonal axes on a Poincare sphere. A controller enables time varying initial and final polarisation states S, Sʹ to be tracked. It also ensures that the birefringence limits of the elements are never reached by carrying out an adjustment procedure. A reduction by a full revolution (2π) for one element (eg 19) can be achieved by varying the transformations of the other elements by not more than π.

Abstract: A refractory lining anchored to a wall (23) of a vessel comprises metal anchors (10) attached to the wall and which support the refractory lining relative to the wall. Each anchor (10) has a curved central web (11) and curved legs (12, 14) which together have a shape that approximates that of the letter C. The anchor also has straight arms (15, 16) extending outwardly from the central web which together have a shape approximating the letter W. The arms and legs improve the ability of the anchor to control the crack pattern that forms in the refractory after thermal cycling, thereby reducing catalyst ingress or coke formation in the cracks.

Abstract: Dans la presse à tambour et à courroie, pratiquement aucune des forces de compression imposées au tambour central (104, 204) n'est transmise au cadre de support (240, 410). La presse exerce une force de compression sur le matériau (108, 208) pressé, en rapport avec la tension de la courroie, bien plus grande que celle obtenue jusqu'à présent. L'invention permet de construire le tambour central (104, 204) de manière à obtenir un flux de chaleur très intense sur la bande pressée. Des tambours appropriés à une telle presse sont également décrits. Certaines des constructions de tambour décrites donnent des résultats améliorés lorsqu'elles sont utilisées dans des presses de ce type connues antérieurement.

Title: Method for manufacture of printed circuit boards.
Inventor: KUKANSKIS PETER E
IPC: B05D1/32
Filed: 1987-06-25
Abstract: Printed circuit boards containing thru-holes requiring metallization are manufactured by first applying to the board material an alkaline strippable resist in a predetermined desired pattern, thereafter applying material catalytic to subsequent metallization, thereafter treating the board with an aqueous alkaline solution to remove catalytic material from resist surfaces without adversely affecting the catalyst at non-resist areas, and then metallizing the non-resist areas. The ability to preliminarily apply the resist pattern before catalyst application, metallization, etc., yet prevent metallization of the resist, enables the manufacturing process to proceed straight through the activation, metallization, etc. steps without need for interruption for resist application.

Abstract: A receiver sheet for dye-diffusion thermal transfer printing, comprises a substrate which supports a receiver coat, the receiver coat comprising a dye-receptive material, such as an organic polymer, and a dye-permeable release agent which is a thermoset amino-modified-silicone organic-oligoepoxide resin. The thermoset combination of silicone and organic moeties in the release agent, gives good protection against adhesion between the dyesheet and receiver sheet when they are subjected to short high temperature pulses during printing, while also enabling sharp images of high optical density to be obtained. This balance of properties is best obtained by dispersing the release agent throughout the dye-receptive material, although they can also be applied to the substrate as separate layers.
