Title: Method and arrangement for producing a bridge for anchorage elements in dentine.
Inventor: ANDERSSON KNUT MATTS GREGER

Abstract: PCT No. PCT/SE87/00574 Sec. 371 Date May 16, 1989 Sec. 102(e) Date May 16, 1989 PCT Filed Dec. 2, 1987 PCT Pub. No. WO88/04158 PCT Pub. Date Jun. 16, 1988.A bridge for an artificial dental structure is made of titanium. The bridge is constructed from modular elements which are adapted one to the other and are treated for joining together, for example by means of laser welding. In a first treatment unit one or more first treatment stages are performed for the construction of the bridge. Identification data introduced or utilized in this or these stages relating to the individual different heights of the anchorage elements above the dentine and their different relative inclinations, and the positions and directions of the modular elements in relation to one another and to the anchorage elements are obtained and stored. In a subsequent processing stage which is executed by a processing unit the latter is controlled depending on the extracted and stored information, so that any bridge elements present in the bridge between the attachment components of the bridge in the anchorage elements are assured a connection via the contact surfaces and directions and dimensions between the attachment components such that the bridge elements are essentially in line with the direction of the dentine in the sense of its height and width, at the same time with the necessary strength and location within the dental structure.

IPC: H01S5/12

Abstract: In DFB/DBR semiconductor diode lasers, competition may arise between the DFB (Distributed Feed-Back) mode corresponding to the period of the grid present and the FP (= Fabry-Pérot) mode determined by the relative distance of the mirror surfaces, as a result of which the laser does not operate in one single mode. 
     By providing an antireflex layer, this problem is suppressed, but other disadvantages are obtained, such as a large line width. 
     According to the invention, by providing a phase layer (30) on the antireflex coating (27), the operation of the laser in a single mode is combined with a comparatively narrow line width. 
     According to the invention, a reflective coating (35) can be applied to the phase layer (30). In this case, both the module and the phase of the effective reflection can be adjusted substantially independently of each other, as a result of which a narrow line width and SLM can be more readily combined. 
     The antireflex coating (27), the phase layer (30) and the reflective coating (35) can be manufactured by means of not more than two materials having a suitable refractive index. According to the invention, two particularly suitable materials are hafnium oxide (28, 32) and silicon dioxide (29, 31), which can be applied to the mirror surfaces by means of the comparatively simple and attractive vapour deposition technique.

Abstract: For removing haze from dewaxed hydrocarbon oil mixture boiling in the lubricating oil range which is hazy, and hazy oil mixture is filtered in the filtration stage (201) of a dewaxing plant which is concurrently filtering undewaxed hydrocarbon oil mixture boiling in the lubricating oil range. Prior to filtering, the hazy dewaxed oil mixture is subjected to pretreatment (in pretreatment stage 204) such as to promote removal of haze from the dewaxed oil mixture during filtering. This pretreatment is carried out independently of the undewaxed oil mixture and involves the introduction of free excess electric charge, for example by charge injection. It can also include dilution/­chilling with an oil solvent (e.g. liquid propane). As an alternative to the pretreatment, the temperature conditions under which filtration takes place may be low enough to promote wax crystalliz­ation. The filtration stage may comprise a rotary drum filter (213) in which the undewaxed oil mixture is introduced into the filter vat (10), whereas the pretreated dewaxed oil mixture is sprayed onto the wax cake formed on the rotary filter drum.

Abstract: A child's play ball constituted by an outer casing (10) and an inner inflatable bladder (11). The outer casing (10) is formed by contoured segments (10A, 10B, 10C) of high strength, non-stretchable fabric material stitched together to define, when the casing is fully expanded, a play ball of the desired shape and size, such as a football or soccer ball. The inner bladder (11) is a conventional rubber balloon whose stem (14) initially projects through an opening in the casing which is provided with a closure (13). The stem (14), after the balloon is inflated with air so that it conforms to the casing (10), is then tied to retain the air, the tied stem (14) being concealed within the casing (10) by the closure (15). The maximum safe diameter of the inflated balloon which is well below the diameter at which the balloon is close to its bursting point, is approximately equal to the maximum dimension of the expanded casing whereby the encased balloon has excep­tional strength and the play ball may be subjected to rough handling.

Abstract: A video graphics system in which an effect can be produced in selected portions of an image held in a first store. Image data in the first store relating to a user defined area of interest in the image is copied to a second store and processed in accordance with a user selected function. The area of interest is selected by the user by magnifying and shifting a displayed representation of the image so that the area of interest is displayed and then selecting a locking function which retains parameters associated with the shifting and magnifying of the displayed image. Once the image data relating to the area of interest has been processed it can be painted onto the image held in the first store to produce the desired effect. By processing only the selected area of interest the speed of processing is increased.

Abstract: A balloon dilatation catheter having a guidewire lumen (12) that extends to the distal tip of the catheter, a balloon (20) mounted on the distal end of the catheter and an inflation lumen (16) extending through the shaft and communicating with the interior of the balloon is provided with an improved arrangement for filling the inflation lumen and balloon with liquid while purging air from the system. The device includes a one-way valve means (41) carried by the catheter shaft within the balloon which permits fluid flow from the guidewire lumen into the balloon under a predetermined pressure greater than about one atmosphere. The system is used by first plugging the distal end of the guidewire lumen and then pressurizing the guidewire lumen with inflation liquid sufficiently to open the one-way valve means to permit inflation liquid to fill the balloon. As the balloon fills, air is forced out of the balloon through the inflation lumen and is vented through the open proximal end of the inflation lumen. The one-way valve means is constructed to preclude reverse flow under pressures greater than 20 atm and to preclude opening in response to aspiration through the inflation lumen at a level not greater than 1 atmosphere pressure.
