Abstract: An apparatus and method for rapidly reading thermoluminescent phosphors to determine the amount of luminescent energy stored therein. The stored luminescent energy is interpreted as a measure of the total exposure of the thermoluminescent phosphor to ionizing radiation. The thermoluminescent phosphor reading apparatus of Figure 1 uses a laser 10 to generate a laser beam 16. The laser beam power level is monitored by a laser power detector 20 and controlled to maintain the power level nearly constant. A shutter 26 or other laser beam interrupting means can be used to control exposure of the thermoluminescent phosphor to the laser beam. The laser beam is equalized such as by using an optical equalizer 31 so that the laser beam has an approximately uniform power density across the beam. The heated thermoluminescent phosphor emits a visible or otherwise detectable luminescent emission which is measured by an emission detector 45 and used as an indication of the radiation exposure of the thermoluminescent phosphors. Also disclosed are preferred signal processing 62 and control circuits 70, 75.

Abstract: An orthopedic device (10), especially a hip joint prosthesis (10) comprising a stem and a spherical head, is formed from a composite material (42, 44) which is reinforced with continuous filament or carbon fibers (26) to provide the material with high flexural strength, hydrolytic stability and a medical grade quality. The stem and spherical head can be formed from a composite block (54). In the alternative, the stem alone can be formed from the block and a head of another material attached to one end of the stem. Sheets of carbon fibers held together by a polymer are rolled in a spiral configuration about an axial direction to form the stem and then molded under heat and pressure. The resulting composite is then machined to form the orthopedic device. <IMAGE>

Abstract: Disclosed is an improved method for coating a zinc surface comprising treating said surface with an aqueous, acidic solution containing: (a) about 0.5 to about 4 percent phosphate ion; (b) an ion selected from the group consisting of zinc ions, manganese ions, and mixtures thereof, said ions being present at a level sufficient to form dihydrogen phosphate with substantially all of said phosphate ions; and (c) about 0.01 to about 1 percent complex fluoride ions; wherein the weight:weight ratio of complex fluoride ions:chloride ions in said solution is at a value of about 8:1 or greater. It is preferred that the ratio complex of fluoride ion to chloride ion (F-:Cl-) in said solution to be maintained at a value of greater than about 8:1, preferably greater than about 10:1, and more preferably greater than about 14:1. The select weight:weight complex fluoride:chloride ratio substantially eliminates the abnormal crystal growth frequently found in treated surfaces while at the same time reduces the need for excess fluoride.

Abstract: Method and apparatus for the reduction of picture data for digital video signals comprising a processing of the signals by means of block by block transformation method so that a transformed and quantized signal which was generated at a time t-1 and placed in an image storage is subtracted from a transformed signal that occurs at a time t and whereby the difference signal obtained is subject to quantization and the quantized difference signal is subjected to an analysis and to a time delay which corresponds to the time requirement for the analysis for updating the content of the image storage. The signal delayed is added to the signal read out from the image storage which is also delayed and is added dependent on the addition condition signal obtained from the analysis and is subjected to an entropy coding dependent on the analysis results with the addition condition signals containing information as to whether a block which has been analyzed has been concluded is a moved or unmoved block and when the block is a moved block containing information regarding a coefficient group to be transmitted. The signal coded in such fashion is subjected to a buffering and depending on the degree of buffer filling a quantization stage and an analysis stage is influenced so that a signal from a buffer control is supplied to the quantization stage for the purpose of selecting one of a plurality of predetermined quantization characteristics and a second signal is supplied from the buffer control means to the analysis stage to select the maximum number of coefficient groups and a third signal is supplied to the analysis stage from the buffer control for the purpose of deciding whether a block is to be transmitted or not and the coefficients represent the digitized video signal transformed by block which is subdivided into coefficient groups.

Abstract: The colour recognition apparatus is arranged so that assigned colour differences and brightness signals are separated from a video signal. The separated signals are determined according to the upper and lower limit values present in a decision circuit giving a binary signal output. Brightness, chroma and hue signals are separated from the video signal and determined according to the limit values. The hue is automatically determined to confirm it by the screen of a monitor to eliminate individual differences and errors  in recognition due to eyesight. The determination can recognise the hue under a uniform condition and determine the area of the object to be inspected.

Abstract: Advantageous crosswire feeding devices are known but these extend through the grid plane. The intention is to provide a crosswire feeding device which is arranged fully outside the grid plane and, as a result, can interact with a conventional crosswire feeding device in order, by virtue of the simultaneous welding of two crosswires, to increase the output of the welding machine. The new crosswire feeding device is furthermore intended to shorten the electrode travel to the greatest possible extent, further increasing the output of the welding machine. The new crosswire feeding device (1) proposes a chain drive (6) which extends obliquely to the grid plane and the lower strand (23) of which is guided parallel to the grid plane in a lower zone. Crosswires (3) are guided between the lower strand (23) of the chain drive (6) and a skid (11), in that region of the chain drive (6) which is parallel to the grid, where they are firmly clamped by a clamping tongue (14) until the following pusher (9) of the chain drive (6) pushes the firmly clamped crosswire (3), counter to the action of the clamping tongue (14), into its predetermined position between the two welding electrodes (4, 5). In this predetermined position, the crosswire (3) is firmly clamped between the pusher (9) and a resilient stop (17, 18), the downwardly moved upper welding electrode (4) pressing the crosswire (3) downwards counter to the action of this second clamping device (9, 17, 18), onto the longitudinal wires (2) and welding them in place there.
