Patent EP-0263454-A2 (EP)
Inventor: ALBERS KLAUS
IPC: F28F3/02
Filed: 1987-10-03
Abstract: A flat heating element consists of at least two wall shells (1, 2) arranged parallel to one another and shaped basically like a sheet, which are rigidly connected to one another circumferentially at the edge to form a flow path for the heating medium between their mutually facing inner broad sides, bear against one another in the regions between their edges, and are spot-welded to one another in the bearing regions. For the purpose of improving the heat output while maintaining the required pressure resistance, the heating element has a design in which the mutually facing inner broad sides of the two wall shelves (1 2) delimit a flat heating medium chamber (12), whose free flow cross-section is partially interrupted only by spot-weld joints distributed between the two wall shelves (1, 2) over the chamber surface. <IMAGE>

Abstract: According to the application, a relatively low molecular weight epoxy resin is reacted with an acidic fusion compound in the presence of a bis(trihydrocarbylphosphine)iminium salt catalyst to produce a high molecular weight fused epoxy resin. The process is particularly useful in reacting an epoxy resin having a molecular weight of less than 500 with 2,2-bis(4-hydroxyphenyl)propane in the presence of a bis(trihydrocarbylphosphine)iminium halide to produce a fused epoxy resin having a molecular weight within the range of 500 to 7000. The catalyst is relatively water-­insensitive, and the reaction can therefore be carried out in the presence of water.

Inventor: RISK WILLIAM P
IPC: H04B10/25
Filed: 1987-02-10
Abstract: An acoustic wave is propagated colinearly with the optical signals in an optical fiber (330) to cause coupling of an optical signal in one propagation mode of the optical fiber (330) to the other propagation mode in the optical fiber (330). The acoustic wave is selected to have an acoustic wavelength which is shorter in the direction of optical propagation than the optical beat length between the two propagation modes of the fiber. In order to cause phase matching between the two optical propagation modes, a periodic structure (340) is used to cause the acoustic wave to contact the optical fiber (330) at periodic locations (342) so that the coupling between the two propagation modes is periodically enabled and disabled. The periodic contact of the acoustic wave with the optical fiber (330) has the effect of adding a spatial propagation constant. The periodicity of the periodic structure (340) is selected so that the spatial propagation constant of the periodic structure (340) is equal to the mismatch in the propagation constants of the two optical propagation modes and the acoustic wave. The present invention thereby provides a means of obtaining greater shifts in the optical frequency while using a colinearly propagating acoustic wave.

Abstract: For an oscilloscope capable of simultaneously displaying a plurality of waveforms on a screen and capable of performing operations with respect to a selected one of the displayed waveforms, a method and apparatus for permitting an operator to select a waveform. A touchscreen mechanism provides input signals to the oscilloscope indicating when and where an operator touches the surface of the screen and a microcomputer within the oscilloscope deter­mines from data controlling the display of each waveform and from the data provided by the touch­screen whether the operator is touching any portion of a displayed waveform. If so, the microcomputer assumes that the operator has selected the waveform touched and reconfigures oscilloscope operation such that operations are performed with respect to the waveform touched by the operator.

Abstract: Known interconnections of this type, namely triple function interconnections have the disadvantage that they have to be operated manually twice to lock the containers. This involves a great deal of work and sometimes entails considerable risks. The new interconnection is intended to allow rapid and largely automatic locking. To avoid the particularly dangerous (second) locking operation of the interconnection between containers placed one on top of the other, automatic locking takes place in the interconnection according to the invention when one container has been placed on top of another. The interconnections can be used wherever several stackable large containers are to be connected to one another, in particular on ships. <IMAGE>

Abstract: A bimorph using ultraviolet setting glue to laminate a piezoelectric film structure, having etched-back metalization patterns on the surfaces of the piezoelectric film. The bimorph is used in a bimorph light modulator including a substrate on which fiber optic input and output light guides are mounted. A gap between the light guides serve as an optical coupling. A bimorph is affixed to the substrate with a shutter attached to one end thereof and positioned within the gap for blocking the light coupling when the bimorph is in the unenergized state. When the bimorph is energized, it pulls the shutter out of the gap, thereby allowing light coupling. Top and bottom stops are used to limit the bimorph movement to damp resonant vibrations and improve on and off times. Viscous air damping is used to eliminate or minimize bounce of the top and bottom stops and to help damp resonant vibration. 
     An array of the bimorphs may be utilized for providing a video or other display, with electrode connections being made to the bimorphs by means of conductors which contact the bimorph electrodes at small surface areas, with the conductors being attached to circuit boards carrying signals for operating the bimorph array. The optical fibers may be coupled to different light sources and filters to provide color images, and groups of optical fibers may be arranged to form pixels for providing a broad range of intensities.

Abstract: In a switching power supply for a television apparatus, a switching stage (SW1) is coupled to a source (31) of DC input voltage and to an energy storage inductance (L1) for developing a source (VO) of DC supply voltage. Operation of the switching stage generates a switched waveform voltage in the inductance (L1). The primary winding (W1) of a flyback transformer (T1) is coupled to and energized by the DC supply voltage (VO). A second winding (W2) of the flyback transformer is coupled to the inductance (L1) and provides a magnetic path, via the flyback transformer (T1), for energy to circulate between the source of DC supply voltage and the energy storage inductance (L1). An auxiliary winding (L2) is magnetically coupled to the inductance (L1) and to a load circuit (46), such as a high power audio stage, for transferring at least a portion of the circulating energy to the load circuit. Additionally, the flyback transformer (T1) may be used to directly transfer (through W4) energy to the load circuit (46).
