Patent DE-3063832-D1 (DE)
Title: Heat-insulated pipe and process for its manufacture
Inventor: BALL HUGO DR RER NAT
IPC: F16L59/20
Filed: 1980-04-08
Granted: 1983-07-28
Abstract: The pipe for the transport of warm or hot fluids comprises an inner tubing (1) forming the transport pipe, an external protective tubing (4) and a heat insulating layer (3) disposed in between. The internal tubing (1) is made of a synthetic material armed with glass fibers and is surrounded by a metallic sheet (2) acting as a vapor screen since the synthetic material is vapor-permeable. In order to avoid the formation of water pockets, the metallic sheet (2) is applied onto the inner tubing (1) without forming air pockets. When the inner tubing is formed of epoxyde resin, a rotational moulding is particularly appropriate whereby the wall of the mould is lined with the metallic sheet (2) for obtaining the inner tube of a part, the metallic sheet forming a construction unit. If the inner tubing (1) is made of a vinylic polyester the metallic sheet may be wound helically around the inner tubing by applying a tension or by pressing it against the tubing in order to prevent the formation of air pockets. To link neighbouring tubes a sleeve (6) of synthetic material is glued onto the naked end of the inner tubing (1) which is also provided with a metallic sheet (2) and comprises a wedge-shaped zone (10) into which the naked end of the neighbouring tubing is inserted and secured by means of a synthetic glue (11). Because the vapor diffusion takes place nearly only in a radial direction, the axial slot between the metallic sheets (2, 2a) does not have any negative influence on the vapor screen in the joining zone, especially if the metallic sheet comprises an axial overlap.

Title: Method of improving maximum density and tonal range of electrographic images and an electrographic copying apparatus using the method
Inventor: KASPER GEORGE PHILIP
IPC: G03G5/14
Filed: 1980-04-15
Granted: 1983-09-15
Abstract: The image quality obtainable by an electrographic copying process in which an electrostatic latent image formed by imagewise exposure of a uniformly charged photoconductive layer, or otherwise, is developed with a toner can be improved if the latent image comprises discrete charge bearing zones, preferably formed by a supplementary exposure through a half-tone screen, and if additionally the toner is electrically conductive either intrinsically or as a result of electrical break-down. In this manner, the maximum density obtainable in a copy can be increased and the contrast decreased sufficiently to allow good reproduction of both continuous tone and high contrast images.

Granted: 1984-05-30
Abstract: Equalizer circuitry for a wideband signal recording/playback system, in particular a home video system, comprises a pre-emphasis and a de-emphasis circuit in the recording channel and the playback channel respectively. In an advantageous embodiment, the pre-emphasis and de-emphasis circuits are of the second-order type. In the preferred embodiment of the circuitry, in each of said channels there is provided a circuit for group-delay equalization, preferably an all-pass filter which comprises at least one substantially symmetrical transistor stage provided with a bridge circuit consisting of at least one reactive impedance and ohmic resistance and located between emitter and collector. Practical embodiments of the bridge circuit comprise several series-connected parallel LC sections and one ohmic resistance. Advantageously, conventional filter stages in the channels may be at least partially included in said circuit for group-delay equalization. Conventional delay means provided in color video systems for equalization of the delay between color and video signals can therefore be integrated in said circuit for group-delay equlization.

Title: Exercise responsive cardiac pacemaker
Inventor: COOK WILLIAM A
IPC: A61N1/365
Filed: 1983-05-05
Granted: 1987-09-17
Abstract: An exercise-responsive cardiac pacemaker is provided which physiologically controls the stimulation rate of a heart by sensing the venous blood temperature in the right ventricle of the heart. A temperature sensing means which includes a thermistor produces an output signal which is sent to an algorithm implementing means for implementing the output signal by an algorithm which represents the mathematical function between venous blood temperature in the right ventricle and heart rate in a normally functioning heart. The algorithm implementing means produces an output signal which is variable between a maximum and minimum level corresponding to the desired maximum and minimum levels of heart rate in a normally functioning heart. The algorithm implementing means is also programmable by telemetry after implantation. A cardiac pacemaker is connected to the algorithm implementing means and is responsive thereto in order to variably control the stimulation rate of the heart.

Granted: 1987-09-17
Abstract: A power supply circuit having a higher power factor and decreased current crest factor. The circuit preferably comprises an input circuit for receiving an input AC voltage and rectifying this voltage and an output circuit for providing a DC output voltage. A pulse-width-modulation circuit intercouples between the input and output circuits and includes a controlled circuit adapted to pass input AC current in pulse-wide increments with the pulse-width varying in inverse proportion to the AC voltage. In this manner, when the instantaneous AC voltage is low, the pulse widths are wider and conversely when the voltage is high, the pulse widths are narrower. In one version of the invention, the pulse width modulation is carried out by a programmed variable ratio transformer. In one preferred embodiment of the present invention, the current spreading circuit is of a quasi cosecant type while in another preferred embodiment of the invention, there is a combination of pulse-width-modulation with a typical input filter circuit including an OR circuit at the output to provide the necessary combining.
