Abstract: ABSTRACT     A strainer device for railroad car air brake combined dirt collector and cut out cocks, and arranged to be applied within the swirl chamber of such cocks, and between the collector bowl, about the pedestal thereof, and the lip of the cock throat chamber, which strainer device comprises an outer shell that is open and flanged at both ends, with one end of the outer shell being disposed adjacent the throat lip, an annular seal applied between the said outer shell one end and the throat lip, an inner shell disposed within the outer shell and secured at the other end of the outer shell and adapted to receive the cock collector chamber pedestal, and a compression spring received about the pedestal within the cock collector bowl and resiliently seated against the outer shell end flange at that end of same for spring biasing the other end of the outer shell and the seal against the throat lip.  The outer shell is formed from a foraminous material defining mesh openings that in total area exceed the area of the cock throat by a factor of at least thirteen, for accommodating possible extensive foreign material occlusion of the mesh openings free of reduction of air flow capacity through the combined dirt collector and cut out cock.  The inner sleeve is optionally provided with a check valve arrangement to provide a stand-by path for air needed to charge and release the brakes in the event that the strainer itself becomes so occluded that it could not pass air through its mesh openings.

Abstract: ABSTRACT     The application describes digital signal processing of radar video signals to provide an optimum display.  Three interacting components of the system are further described in detail:  a global mean estimating circuit, a statistical analyzer circuit, and a dynamic range compression circuit.          The global mean estimating circuit determines the mean of the amplitude distribution of video signals over a wide section of the display as opposed to a local mean of signals.          A local mean of signals is the mean of the amplitude distribution of video signals occurring in the near vicinity of a point on the display.  The statistical analyzer circuit evaluates the amplitude distribution of video signal samples and controls the gain of the signal path so that the variance of the sampled amplitude distribution follows the variance of a model distribution.  The dynamic range compression circuit functions to compress the range of amplitude distribution in a manner to provide maximum information from the display.

Abstract: ABSTRACT           A flexible pipe coupling for the end portions of two pipes has an elastic sleeve whose open ends receive the end portions of the pipes and which has a centrally located partition extending from its internal surface and abutting against the end faces of the inserted pipes.          The partition is flanked by two internal grooves which are formed in the internal surface and are flanked by annular surfaces sloping inwardly toward the partition.          The external surface of the sleeve has a centrally located outer groove and is surrounded by a split ring forming part of a clamp and having apertured lugs extending outwardly from the two end portions of the ring to be moved nearer to each other by a bolt and nut assembly whose shank extends through the apertures so that the sleeve is compressed and its internal surface sealingly engages the external surfaces of the pipes.  The split ring has a corrugation which extends into the outer groove of the sleeve.  A second corrugation is provided on an arcuate insert which is placed between the split ring, in the region of its end portions, and the external surface of the sleeve and such second corrugation also extends into the outer groove of the sleeve.  The marginal portions of the split ring have a frustoconical shape and bear against the external surfaces of the respective pipes when the ring is caused to bear against the external surface of the sleeve.

Abstract: METHOD AND APPARATUS FOR SURFACE DIAGNOSTICS     ABSTRACT OF THE DISCLOSURE           Method and apparatus for mass spectral analysis of unknown species of matter present on a surface even in extremely low concentrations.  A probe beam such as an ion beam, electron beam or laser is directed to the surface under examination to remove a sample of material.  An untuned, high-intensity laser is directed to a spatial region proximate to the surface. The laser has sufficient intensity to induce a high degree of nonresonant, and hence non-selective, photoionization of the sample of material within the laser beam.  The non-selectively ionized sample is then subjected to mass spectral analysis to determine the nature of the unknown species

Abstract: ABSTRACT          METHODS OF AND CIRCUIT ARRANGEMENTS FOR          COMPENSATING CROSS-TALK AND/OR ECHO SIGNALS:              An adaptive cross-talk and/or echo compensation cir-cuit is arranged on the four-wire (VL) side of a hybrid circuit (G) and has a variable filter (KF) and a compensation signal logic-linking element (K), the compensation signal being formed in dependence upon the difference value, possibly averaged, between the output signal of a decision device (E), which signal is formed following signal compensation and adaptive signal equalisation steps, and the decision device input signal value, the filter coefficients being set in accordance with the compensated received signal, or the sign thereof, if the difference value is great and being set in accordance with this difference value, or the sign thereof, if the difference value, possibly averaged, is relatively small. A compromise equalisation of the received signal can take place prior to the cross-talk and/or echo compensation. Following compensation, regulated amplification may be effected, if the setting signal for the variable filter is derived from the difference between the decision device output signal and the decision device input signal, and if the filter setting signal which corresponds to the compensated received signal is derived from the compensated and amplified received signal, then each of these setting signals may be multiplied by a factor which is reciprocally proportional to the amplification factor.

Abstract: TWO-CABLE SHIFTING MECHANISM FOR TRANSMISSIONS            Abstract of the Disclosure In a remote shifter for a vehicle transmission, a transmitter unit is located near the vehicle operator while a receiver unit is mounted on the transmission. The transmitter and receiver are coupled by flexible push-pull cables that transfer the motion of a gearshift lever operated by the vehicle operator to the transmission to select and engage the desired gears in the transmission. The shift lever is operable in two independent modes of pivotal motion about orthogonal axes. Motion in a first mode controls gear rail selection in the transmission and motion in a second mode controls gear engagement. The transmitter couples the gearshift lever to the cables so that pivotal motion of the gearshift lever in a transverse plane is translated to linear motion of the select control cable while pivotal motion of the gearshift lever in the fore/aftplane is translated to linear motion of the shift control cable. The transmittermaintains the motion of the two cables independent of one another. The receiver translates linear motion of the select control cable into linear motion of an output shaft that couples the receiver to the vehicle transmission and translates linear motion of the shift control cable into rotational motion of the same output shaft. The receiver linkage maintains independence of the motions of each of the cables and maintains independence of the two modes of motion of the output shaft.

Abstract: PROCESS FOR PREPARING ESSENTIALLY COLORLESS POLYIMIDE  FILM CONTAINING PHENOXY-LINKED DIAMINES                 ABSTRACT OF THE DISCLOSURE    An aromatic condensation polyimide film that is approximately 90% transparent at 500 nm, useful for thermal protective coatings and the like, and the processes for preparing same by thermal and chemical conversion are disclosed.  An essential feature of the invention for achieving maximum optical transparency films requires utilizing recrystallized and/or sublimated specific aromatic diamines and dianhydride monomers and introducing phenoxy or thiophenyl separator groups and isomeric m,m'- or o,p'-oriented diamines into the polymer molecular structure. The incorporation of these groups in the polymer structure serves to separate the chromaphoric centers and reduce the formation of inter-chain and intra-chain charge transfer complexes which normally cause absorptions in the UV-visible range.  The films may be obtained by hand, brushing, casting or spraying a layer of the polyamic acid solutions onto a surface and thermally converting the applied layer to the polyimide or the polyamic acid solution can be chemically converted to the polyimide, subsequentially dissolved in an organic solvent, and applied as a polyimide film layer with the solvent therein thermally removed.

The decoder   comprises   a   correlation   detecting  means comprising   a   matched   filter   which   produces   a back-diffusion signal when a received spectrum diffusion signal  correlates  with  a Gold  code  for  a  specific channel  of  a station,  an extraction signal generator means for detecting the epoch position of a peak of a triangular  wave  which  appears  in  the  output  of  the correlation detecting means when correlation between the spectrum diffusion signal  and the specific Gold code identifying  the corresponding channel  is established, and a data output extracting means responsive to the extraction signal to extract the back-diffusion signal and reproduce the resulting data.  In this arrangement, the extraction signal generator means is responsive to the   peak   of   the   triangular-form  wave   in   the back-diffusion  signal  from  the  correlation  detecting means to output the extraction signal.   The extraction signal is sent to the data output extraction means to extract back-diffusion signal  from the output of the correlation.  detecting  means  and  reproduce  the  data output.
