Abstract: A power supply for an electroerosion machine having a switching element (TR1) which controls the machining current in the gap (G). The value of the current is compared with a predetermined voltage (VR1) and the signal generated based on this comparation is provided to a logic gate, advantageously an "AND" gate (A1), whose output signal is applied to the control electrode of the switching element (TR1). The power supply surpresses any arcing tendency during gap short circuit conditions and increases the total current through the gap even when gap voltage is low in order to maintain a high machining rate. Electrode consumption is reduced by using a generally step-type current waveform signal. Machining current during the discharge period may be controlled to more closely approximate a square wave so that shifting to a faster machining rate can be easily accomplished by accepting some sacrifice in electrode consuption. Preferably, two or more switching and gating devices are used to permit gap current to flow intermittently during the entire discharge period.

Abstract: A circuit arrangement is described for generating pulses for maintaining the oscillations of a resonance circuit after termination of an outside stimulation of the oscil­lations by means of an HF carrier oscillation. The circuit arrangement comprises an energy storage element (28) charge­able by the HF carrier oscillation to a supply voltage value. An amplitude detector circuit (44) serves to generate a trigger circuit when the oscillation amplitude of the reson­ance circuit (12) drops beneath the supply voltage value. A first switching element (T2) supplies the oscillations of the resonance circuit (12) under the control of the trigger signal to a delay circuit (34, 52, 58, 54, 62, 68) which at its output furnishes switching pulses with a predetermined phase position with respect to the oscillations of the resonance circuit (12). A second switching element (T1), for the duration of each switching pulse, enables the supply of energy from the energy storage element (28) to the res­onance circuit (12).

Abstract: The alkoxidation products of alkylphenols and fatty alcohols with alkylene oxides prepared by known processes have high alkylene oxide and 1,4-dioxane contents. This is undesired from possible toxicological points of view. The novel process should not have these disadvantages. For this purpose, a process is proposed in which the fatty alcoholates obtained in the alkoxidation by direct reaction of alkali metal hydroxide with fatty alcohols are used as catalysts. The products prepared by this process have residual contents of alkylene oxide of below 1 ppm and 1,4-dioxane of below 3 ppm.

Abstract: For the continuous drying of wet-processed, pasty material, the latter is conveyed by means of an extruder (1) into a vacuum zone, which may be formed for example by a vacuum belt dryer (10). The heating of the material caused by the extrusion leads to a rapid expansion and drying in the vacuum. Depending on the product, it is no longer necessary to supply additional heat. Consequently, the residence time of the material in the vacuum can be reduced, whereby the product output can be increased. Furthermore, it is possible to operate at lower temperatures, as a result of which the quality of the material is not impaired.

Abstract: A process for methylating the N 4  atom of a polysubstituted piperazine or piperazin-2-one ("PSP") is effective despite using a much smaller molar excess of formaldehyde and formic acid than dictated by a conventional Eschweiler-Clarke reaction. Particularly in a complex amine in which the PSP substituent is connected to a triazine ring which in turn may be connected to a N atom of an acyclic polyamine, the molar ratio of NH groups : HCHO : HCOOH is in the range from about 1:1:1 to 1:1.5:1.5, the amount of HCHO and HCOOH being sufficient to methylate at least the
     groups of said PSP substituent if the complex amine contains terminal -NH groups. The same range of molar ratio is maintained when the total number of NH groups to be methylated includes the terminal -NH groups. The effectiveness of the process is attributed to use of an alkylbenzene solvent in which reaction with only a slight excess of HCHO and HCOOH proceeds apace, and in which solvent the methylated product remains dissolved. The excess HCOOH is neutralized with aqueous alkali. When the solution of methylated product is washed with water, the partition coefficient is at least 0.90 and typically 0.99, so that less than 1% of methylated product is lost in the aqueous wash. More than 90% yield is obtained by harvesting the methylated product from the solvent phase alone. The methylated product is precipitated from the alkylbenzene solution by addition of a precipitating agent, such as heptane. The reaction may be carried out under essentially dry conditions with less than 3% water present; or, it may be carried out under wet conditons (less than 30% water).

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: In recording and reproducing the digital video signals by bit rate reduction, if they are copied under the state of being subjected to bit rate reduction, no accumulation of distortions in orthogonal transformation or bit rate reduction occurs, and moreover, copying can be done at a low data rate. On the other hand, in case of dividing the data into blocks in each page and transmitting or recording and reproducing the data by block, by concealing the error by the data having the stronger correlation out of the data located in the pages before and after the block in which error has been detected, no degradation in image quality is induced even when the scene changes between pages. Further, at the same time, by detecting the previous concealment information, if there exists a block which was previously concealed in the block in which error has at present been detected, then the data can be fully reproduced by utilizing it, and degradation in image quality can be suppressed to the minimum extent. Also, if degradation in image quality is suppressed to the minimum extent, then the degradation in   image quality in the case of repeated copying is to be suppressed to the minimum extent.

Abstract: A solid state touch or control button assembly ( 10 ), with no moving button parts and operated by capacitive sensing by monitoring the phase shift of a signal applied to the face of the button, including in a first embodiment ( Figs. 2A & 2B ) auto balancing operation and in a second embodiment ( Figs. 3A & 3B ) a constant pressure operation. If skin or other material comes into contact with the touch surface (1), the capacitance is changed and sensed, causing the electrical or electronic function controlled by the touch button to be activated (or deactivated, depending on the design, or otherwise altered). LEDs then are activated, providing visual feedback to the button pusher through a light ring ( 2A ) surrounding the button surface ( 1 ). False activation of the button by residual impedance and external influences, such as temperature change, cleaner residue build-up and other deposits, are avoided by compensating for them by slowly auto balancing to all such phase shifts, with the rate of auto balance being set to be faster than the rate of change of the steady state phase shift; and, additionally, false activations by noise transients, including those due to EMI, RFI and other environmental fluctuations, are avoided by delaying the activation of the button by an appropriate amount of time, such as, for example, of the order of about one hundred (100 msec.) milliseconds.
