Abstract: An apparatus for making and method for forming a dental prosthesis in situ in an edentulouos space defined either adjacent to two existing teeth or between a fixed tooth and a second tooth posterially positioned with respect to the first tooth, and lightly touching the associated gum surface, utilizes a bridge bar assembly (30) having at least one shaped connecting member to be adjustably mounted and connected in the drilled grooves of adjacent teeth, a boss (32) on the bridge bar assembly, and a pontic base (44) adjustably mounted on the boss such that when the bridge bar assembly is in assembled position in the edentulous space for connection to the teeth, the pontic base lightly touches the gum, two spaced mold halves can be placed on the buccal and lingual sides of the edentulous space in which the bridge bar assembly is mounted, (or alternatively, two mold halves with predetermined holes to receive each end of the bridge bar and to permit retention and packing of plastic or pontic forming material), the pontic base can be adjusted relative the associated gum surface to fix the connecting member for the bridge bar assembly relative the drilled section of the teeth, and the edentulous space between the mold halves can be filled with a pontic forming material to form the pontic surrounding the boss on the bridge bar assembly; making the pontic forming material catalytically or chemically set; removing the mold halves; removing the assembly and polishing the sides and undersurface of the pontic or pontics; partially filling the grooves with a filler material; cementing the connecting member in the drilled grooves of the teeth to secure the pontic or pontics in the edentulous space; and applying a cosmetic veneer to the formed pontic or pontics.

Abstract: A heads-up display (HUD) system employs a cholesteric liquid crystal combiner (20), an image source (22), and collimating optics (24) to combine a generated image with an image in an observer's field of view. The cholesteric liquid crystal combiner has a bandwidth, B, around a primary wavelength of maximum reflection, and the image source projects its images within bandwidth B for high efficiency of reflection. Outside bandwidth B the cholesteric combiner has a high efficiency of transmission. Images from the image source are projected upon the combiner which reflects the images toward the observer, together with images from the outside environment in the line-of-sight of the observer. Collimating optics are used to focus the projected images at a distance away from the observer.

Abstract: A data processor comprises a central processing unit; an interrupt request generating means for generating a processing request in asynchronism with the central processing unit; an interrupt controller receiving the processing request from the interrupt request generating means; and a data memory for storing processing data. The interrupt request generating means is capable of selectively generating a first processing request which requests to start a first data processing branching an operation to a predetermined address after saving contents of a program counter and a program status word of the central processing unit to the data memory, and a second processing request which requests to start a second data processing while maintaining contents of the program counter and the program status word. The data memory stores control information for executing the second data processing. The interrupt controller receives the first and second data processing requests from the interrupt request generating means, and operates to output to the central processing unit an interrupt request signal corresponding to a received processing request. The central processing unit receives the interrupt request signal from the interrupt controller, and operates to interrupt execution of an instruction being executed and to selectively start either the first data processing or the second data processing. Thereafter, the central processing unit operates to start the interrupted instruction execution after the started first or second data processing has been completed. Furthermore, the central processing unit operates to continuously execute the second data processing on the basis of the control information stored in the data memory.

The chamber is open to the moving film via an inlet slot and an exit slot. Pairs of conveyance rollers are positioned just upstream and just downstream of said inlet and outlet slots, respectively. Liquid conveyance means pumps a processing liquid through said chamber and picks up the processing liquid exiting the chamber via the slots and being squeezed off the film by the rollers.

Abstract: The invention relates to a shuttle guide on flat looms, in which a shuttle rotates on a closed path, composed of the path portion in the shed along the weaving reed, the opposite return path portion and the reversing arcs connecting these portions, and is pivotable out of the shuttle path by a pivoting device. A shuttle guide of this type is to be designed so that frictional contacts between the shuttle and the warp yarns are avoided and the heating of the shuttle has no harmful effects on the warp yarns, without the measures to be taken impairing the operating reliability of the loom or having an adverse affect on the weaving process. This is achieved in that the shuttle guide consists of individual plate- like and/or wire-like bow-shaped lamellae which are arranged in series at a distance from one another in the weft direction and which so surround the shuttle that it does not touch either the cross-shed or the lower shed when it slides or rolls through the shed, and which can be pivoted in and out jointly relative to the shuttle path by means of a pivoting device.

Abstract: Atmospheric air is introduced into reference (20) and sample (21) chambers, whereupon alternating circulation of the gases in the two chambers through a carbon dioxide sensor (15), an oxygen sensor (16), a pressure indicator (17) and a pressure regulator (18) occurs before the gases are returned to their respective chambers (20, 21). The calculation of rate of production or consumption of carbon dioxide and oxygen by a tissue or other sample in the sample chamber (21) is controlled by a microprocessor (27, 28) which receives signals from the carbon dioxide (15) sensor oxygen (15) sensor and pressure indicator (17) and controls the circulation of the gases. Sensor drift is compensated for in the calculations through the use of multiple reference chamber readings and through volume determinations for the reference and sample chambers and the sensors.

Abstract: The invention provides a method and kit for the determination of NAD(P)H in a sample, e.g. a clinical sample, which comprises reducing pyruvic acid or a salt thereof with NAD(P)H in the presence of lactate dehydrogenase to form lactic acid, oxidizing the lactic acid in the presence of lactate oxidase to form hydrogen peroxide and determining the hydrogen peroxide by reaction with peroxidase in the presence of a chromogen unsusceptible to NAD(P)H. 
     The method is especially useful in determination of analytes, e.g. bile acid, phosphohexose isomerase, in serum containing lactic acid, in which case the sample is initially reacted with lactate oxidase to convert the lactic acid to pyruvic acid and H₂O₂, which is then decomposed, the pyruvic acid produced in that case providing at least a proportion of the pyruvic acid which is subsequently converted back to lactic acid.
