Title: Improved ceramic compositions and methods employing same.
Inventor: EVANS JAMES G
IPC: A61K6/884
Filed: 1988-05-13
Abstract: Disclosed are ceramic compositions which have been improved through the addition of a light-curing resin. Porcelain compositions are formulated to include a light-curing resin, generally of the acrylic monomer type, molded into a desired shape, and subjected to an appropriate light source to preset the molded object, for example, a porcelain inlay or margin. The present ceramic object having a thus improved integrity is transported or further manipulated, and then fired in a conventional porcelain firing oven. Ceramic compositions made in accordance with the present invention may be employed in all types of dental restoration procedures, including the fabrication of margins, inlays, crowns, laminates, as well as various non-dental applications.

IPC: C04B28/18
Filed: 1988-09-02
Abstract: Zum Entsorgen von salzhaltigen Stäuben von Abfallverbrennungsanlagen werden die salzhaltigen Stäube 
mit ande­
ren Abfallstoffen, wie Aschen und Flugstäube aus mit Steinkohle oder Braunkohle befeuerten 
Wärmeerzeugungsanlangen, 
Quartzsande enthaltende Abfallstoffe der Gießereien, Abfallstoffe der Calciumcarbidherstellung, unter Zusatz 
von Wasser 
intensiv gemischt, wobei die Mischung mindestens 8 % hydrothermal umsetzbares Calciumoxid bzw. äquivalente 
Mengen 
anderer hydrothermalumsetzbarer Calciumverbindungen enthält und der Wasserzusatz so bemessen ist, daß eine 
optimale 
Verdichtung möglich ist und die Mischung danach unter Verdichtung zu standfesten Formlingen verarbeitet wird 
und die 
Formlinge anschließend in einem Autoklav bei einem Sattdampfdruck von mindestens 1 bar gehärtet werden.  
     Abstract 
     In order to remove salt-containing dusts from waste incinerating plants, the salt-containing dusts are 
intimately 
mixed with water and other waste products, such as ashes and flue dust from heat generating plants fired with 
hard or 
brown coal, silica sand-containing waste products from foundries, and waste products from the production of 
calcium car­
bide. The mixture contains at least 8 % hydrothermally convertible calcium oxide or equivalent amounts of other 
hydroth­
ermally convertible calcium compounds and the amount of water is calculated to ensure an optimal density of the 
mixture. 
The mixture is then condensed and process to form solid bricks, and the bricks are finally hardened in an 
autoclave at a 
saturated steam pressure of at least 1 bar.

Abstract: According to this method, on transmission, the signal S1(t) from a low-rate digital channel is added to that S2(t) from a high-rate digital channel by over-modulation or superposition means (13) which generate a composite transmission signal S(t). On reception, the signal S2(t) from the high-rate digital channel is recovered thanks to regeneration means (24) operating on the composite transmission signal S(t). The signal S1(t) from the low-rate digital transmission channel is recovered thanks to means (25) for subtracting the composite transmission signal S(t), previously filtered by a first low-pass filter (31), and the regenerated signal S2(t) from the high-rate digital channel, previously filtered by a second low-pass filter (33).

Abstract: A socket device for a ball and socket coupling has a body (1) and a primary latch member (9) which combine to provide a socket by which it can be hitched to a ball, the primary latch member being held in the operative position by a spring-loaded (23) secondary latch member (15). This can be secured in a position trapping the primary latch member (9) by a lock (22) mounted in the secondary latch member (15). The lock may be fixed or be in the form of a spring-loaded plunger. When unlocked, the spring (23) that biases the plunger acts through the latter also to provide the bias for the secondary latch member. When the plunger is pressed down, it can be locked to the secondary latch member and the fully compressed spring (23) then provides an abutment preventing movement of the secondary latch member (15).

Title: A method of imaging a random medium.
Inventor: BARBOUR RANDALL L
IPC: A61B6/03
Filed: 1989-06-08
Abstract: A non-invasive medical imaging technique capable of evaluating, in situ, the oxygenation state of body tissues (2) (e.g., by measuring the spectral properties of heme proteins) is described. The disclosed technique employs a multi-wavelength collimated source (1) and a collimated receiver (6) and performs a positional and angular scan of the scattered radiation for each position of the incident beam. The resultant data is evaluated by employing imaging schemes which give differential weights to the contribution of various volume elements in the medium to the detector responses at various frequencies. These measurements yield physiological information while being, for example, an indicator of physiological stress caused by disease or trauma.

Abstract: Substrates for growth from solidified melts which have greater contact surfaces with respect to the substrate surface are described, which contact surfaces are distributed so that the growing melt layer is located on them and, owing to the surface tension, is self- supporting and kept separate from the substrate surface.

Abstract: In this method, a disordered staple fibre material is rendered uniform and parallel in order to produce representative textile fibre samples. For this purpose, a piece of the original fibre material (6) to be analysed is brought between two parallel plates (1, 2), which are arranged at a constant distance from one another and have oppositely acting needles with a saw-tooth profile (3, 4) which engage in the fibre material (6). The two plates (1, 2) are now moved relative to one another while maintaining the mutual distance, and this brings about a linear separation of the fibre material (6) into its individual fibres. It is then possible to use a sample clamp (5) to extract from the parallel fleece thus produced a random, orthogonal cross-sectional sample (11) whose composition corresponds largely to the original fibre material (6), and which is therefore suitable for carrying out the most varied quality tests.

Abstract: A near field optical microscopy method and apparatus eliminates the necessity of an aperture for scanning a sample surface (18) and greatly reduces the detected background signal. A small dimension tip (14), on the order of atomic dimension, is disposed in close promity to the sample surface (18). A dither motion is applied to the tip (14) at a first frequency in a direction substantially normal (22) to the plane of the sample surface (18). Dither motion is simultaneously applied to the sample (20) at a second frequency in a direction substantially parallel (24) to the plane of the sample surface (18). The amplitude of the motions are chosen to be comparable to the desired measurement resolution. The end (12) of the tip (14) is illuminated by optical energy. The scattered light from the tip (14) and surface (18) is detected at the difference frequency for imaging the sample surface (18) at sub-wavelength resolution without the use of an aperture. Alternatively, the tip (14) is maintained stationary and the sample (20) undergoes motion in the two directions.
