Abstract: A reinforced structural component is manufactured by forming an intermediate structural member which defines a channel extending along at least a portion of its length. A support member is disposed in the channel and affixed to the intermediate structural member. A second forming operation is carried out on the combination of the intermediate structural member and support member so as to partially enclose and fixedly retain the support member therein. The method may be applied to metallic and nonmetallic structures, and may be utilized in conjunction with high speed metal forming processes such as roll forming. Disclosed herein are structures made according to the method as well as use of the method in the manufacture of structural components for motor vehicles.

Abstract: A formed beam for use as a vehicle bumper having an elongated body exhibiting front and rear opposing surfaces and top and bottom surfaces interconnecting the front and rear surfaces, such that the beam defines a swept shape between first and second opposite ends. A plurality of spaced apart and transverse extending beads are formed upon the top extending surface of said beam and at least a portion of one of the front and rear surfaces are inwardly displaced relative to each other and during formation of an arcuate profile to the beam, and such that the front and rear surfaces exhibit at least partially non-parallel surfaces.

Abstract: A bumper system for an automotive vehicle includes a rolled steel tube having a box or C-shaped cross section fixed to the forward ends of the side rails of the vehicle so as to extend transversely to the vehicle's longitudinal axis. The forward surface of the vehicle is formed by a plastic fascia which may have sloped surfaces for styling or aerodynamic reasons. The space between the forward end of the bumper bar and the fascia is filled with foam intended to absorb energy in an impact. To better match the sloped sections of the fascia, certain sections of the bumper bar are twisted about the longitudinal axis of the bar to create surfaces inclined relative to the vertical. The bars are formed by roll forming a steel web into an elongated member having generally vertical opposed faces. A section of the rolled member is heated above a metallurgical transition temperature.

Abstract: A method and system for producing a temperature image of an object by the use of a television camera head responsive to temporal changes in infrared energy and operating in accordance with the pyroelectric effect. A chopper modulator alternately inhibits and facilitates transmission of thermal energy from a subject to the television camera head viewing the subject. Video information produced during separate first and second time intervals is separately stored. Video information produced during a third time interval between the first and second time intervals is not used. Video information produced during a fourth time interval subsequent to the second time interval is also not used. A signal is produced which is a function of the difference between the stored video information corresponding to the first and second time intervals. This difference signal is employed, in combination with appropriate synchronization signals, to drive a television monitor to produce a thermal image of the viewed subject.

Abstract: In order to transmit in a simple manner in a railway system informations from a ground station provided at the rail level to a railway vehicle, a plurality of transmitters (5) and receivers (4) are arranged one after the other in the longitudinal direction of the railway track and are used as coding elements (1,2,3) of a coding group and cooperate individually and one after the other with a code converter (9) upon the passage of a vehicle on the rails provided with a corresponding code converter (9)-like ground station. The isolated coding elements (1,2,3) comprised of transmitter (5) and receiver (4) form the parts of a resonant circuit which is synchronized with the frequency of the code converter (9) and which draws the whole energy required for its return from the transmission power of the code converter (9).

Abstract: In order to clearly reveal modifications, even small alterations occurring in a controlled object space (1), the thermal infrared radiation of the object space (1) is represented by means of an infrared objective (2) on two different infrared detectors (3, 4; 3', 4') and having each different spectral selectivity characteristics. Those two representations are serially scanned to form two sequences of electrical signals (5, 5'). One of those signal sequences (5') is reproduced on a television monitor (7) directly in a predetermined color (8') and the reproduction of the other signal sequence (5) is delayed and is effected in another color (9').

Abstract: For recording on, and reading of, a magnetic tape guided around a cylinder, there are several magnet heads arranged on a common circle diameter. The magnet heads revolve about a common axis extending obliquely with respect to the travel direction of the tape. The magnet heads interact with the tape through a slot-shaped aperture formed in the cylinder.For the purpose of achieving a very simple tape-guiding system, the tape is guided in a direction perpendicular to the cylinder longitudinal axis over a cylinder surface which, at least in its tape-guiding zone, and viewed in a section perpendicular to the cylinder longitudinal axis, corresponds at least approximately to a projection of the circular motion performed by the magnet heads in a direction perpendicular to the tape travel direction.

Abstract: Video information is recorded and stored on an information carrier in the form of a signal sequence corresponding to a sequential scan of two images of a moving colored motif. The two images correspond to interlaced color extracts. The recorded signal sequence is divided into two, one for each of the two images and these split into three primary color signals for application to a domestic color television receiver set.

Abstract: A video signal sequence, corresponding to a chromatically double-sequential, nesting, interlace scan is used to obtain the simplest possible devices for the recording, transmission and/or storage of a color televison image. Two signals associated alternately line by line with different color separations, are used to this end. One of the signals also contains two signal components, which are associated in line portions with two different color separations. The video signal sequence is repeated line by line, half-frame by half-frame or frame by frame, prior to image reproduction and thus results in an image reproduction, from one and the same signal sequence, of good quality when using simple apparatus and of subjectively perfect quality when using more complex apparatus.

Abstract: An axially symmetrical image is interrogated by means of a Z-shaped scanning raster to permit a simple color picture recording, which however contains all subjectively necessary elements. A scan of each of the two symmetrical images with a quadrupled interlace raster is produced. Video signals are repeated prior to image reproduction in order to avoid line creep. Repetition of one and the same video recording can be performed line by line, for example for video films intended for domestic use, and can be performed frame by frame for studio reproduction.
