Abstract: Rapid differentiation between viable gram-positive and gram-negative bacteria is accomplished with certain polypeptide antibiotics which are used in combination with a compound which is normally reducible by the bacteria. The antibiotics selectively inhibit the reduction of the reducible compound by gram-positive bacteria but do not substantially affect the reducing capacity of the gram-negative bacteria. The particular antibiotics useful are cyclic polypeptides which affect the function of the cytoplasmic membrane of bacteria. A particular polypeptide antibiotic, polymixin B, will distinguish  Proteus  bacteria from other gram-negative genera.

Abstract: An improved camera for recording stimuli received by the pilot of an aircraft. The camera features an improved mount for alignment of a charge-coupled device image forming element with respect to the hous­ing of the camera. The improved mount comprises inner and outer eccentric adjustment members fitting within a bore in the camera housing. Each adjustment member comprises a cylindrical outer surface and a cylindri­cal bore, the axes of the cylindrical bores and cylin­drical outer surfaces being parallel to but not coin­cident with one another, such that axial misalignment of an image forming element mounted on the inner adjustment member may be corrected by relative rota­tion of the adjustment members. Skew adjustment may also be provided. 
     During assembly, the camera according to the invention is mounted on an alignment fixture bearing a predetermined relation to a target. A video image of the target provided by the image-forming element is displayed on a cathode ray tube display device for comparison to a reference image. The inner and outer adjustment members are rotated until the images are aligned, and are then locked. The aircraft contains a camera mount which is in fixed predetermined relation to an object which is to be imaged precisely.

Abstract: So that a fitting can be made especially narrow and also be used for opening to the right and to the left, whilst at the same time the load-bearing capacity will be preserved despite the reduced width (10), the upper scissor bearing (6) consists of a carrier plate (16) and of two separately produced bearing parts (13 and 14) mounted, especially rivetted, onto the plate-shaped support plate (6). These are equipped with bearing lugs (11 and 12), between which is mounted the end of a scissor arm (7) or of set-out scissors which is fixed to the frame. Whilst the two bearing parts (13 and 14) are preferably produced from die-cast zinc, the carrier plate (16) consists of steel, thus guaranteeing the high load-bearing capacity, whilst ensuring a comparatively small cross-section. A high load-bearing capacity is also guaranteed by the use of a carrier body (37), designed as a corner angle, for the lower corner bearing (5). The load-bearing capacity is ensured by the use of a carrier journal (44) and of a stop member (50) on the bearing block (39), rotatable about the axis (38), for the bearing journal (8). <IMAGE>

Abstract: A method for automatically finding color bars within a television video signal checks for a black burst at the end of a horizontal video line to determine the appropriate color bar standard for testing. Then a reference color burst, such as the yellow color burst, is searched for in the appropriate location within the horizontal line. Related color burst locations are demodulated to produce related color angles which are checked for relationship with the reference color burst. Also the luminance amplitudes for each color burst are compared to each other to determine whether a correct amplitude relationship is present. Each horizontal line of a picture frame is tested until either the color bars are found or all the horizontal lines have been tested. The found color bars are displayed in an appropriate format together with the line number within the picture frame, or a message indicating no color bars is displayed.

Abstract: The invention relates to a process for examining components being produced or in use and which have internal defects with the aid of ultrasonic signals, in particular in the case of thick-walled components such as forgings. The ultrasonic probe is guided along a line over the surface of the component, while a synthetic aperture is assigned electronically in a computer to the ultrasonic signals and the signals are subsequently represented in a memory. The received signals are averaged and further processed depending on the density of test data for the purposes of image reconstruction or pattern recognition, after which in the case of components which are still being processed the deformation conditions are set such that a tolerable defect measure used for comparison is undershot, while in the case of components already in use their exchange is undertaken upon overshooting of a tolerable defect measure. <IMAGE>

Abstract: In the position measuring device according to Figure 1, a first grating (2) is illuminated in a so-called three-grating measuring arrangement at a specific angle ( alpha ). Two component beams (3, 4) obtained at the first grating (2) by diffraction impinge on a second grating (5) which represents the measure of the position measuring device. Renewed diffraction forms component beams (6, 6'; 7, 7') of which the two component beams (6 and 7) closest to the grating normal (0) impinge on a third grating (2') with the aid of which they are diffracted once again and caused to interfere. After the third grating (2') the component beams (8, 9 and 10, 11) whose intensity has been modulated by interference impinge on photodetectors (12, 19), which convert them into phase-shifted electrical signals and supply them to an evaluation device (not shown in more detail).

Abstract: Trickle bed reactors are prone to channelling, flood­ing, and similar flow problems. It has been found that these problems can be avoided by the use of a microporous membrane to separate a reactant fluid phase from a catalysis fluid phase surrounding a catalyst bed. An advantage of such a reactor is that the fluid flows can be separately controlled. An apparatus useful as a trickle bed reactor can include a plurality of microporous hollow fibers arranged in a shell-and-tube configur­ation within a housing. Such an apparatus is operated with a reactant fluid phase flowing through the fibers and with a catalyst bed on the shell-side of the arrangement.

Abstract: A method of making a current sensor device is disclosed wherein a sensor, having a magnetoresistive element configured into a bridge (9), an insulating substrate (2) and a conductive member (5) are sub-assembled and then the sub-assembly is heated to bond the components together. The bridge (9) is attached to a first substrate having a first layer of insulation (16) with first vias (17) therein in which are deposited first elements (12a) of (e.g.) solder projecting beyond the first layer of insulation. Second elements (12b) of (e.g.) solder are deposited in second vias (17) in a second layer of insulation (19) on the second substrate (2). When the components are sub-assembled, the first elements (12a) rest on the second elements to provide a clearance between the first and second layers (16, 19) of insulation. Heat is applied to the sub-assembly in a controlled manner so that the (solder) elements (12) melt sufficiently to cause a degree of self-alignment between the bridge (9) and the conductive member and to cause the bridge (9) to be disposed at a predetermined distance above the conductive member (5).
