Title: Process for improving the plating characteristics of boron rich cubic boron nitride
Inventor: CORRIGAN FRANCIS RAYMOND
IPC: C25D5/54
Filed: 1982-02-09
Granted: 1985-03-14
Abstract: Boron rich cubic boron nitride suitable for use in electroplating processes (e.g. nickel plating) has been made by an acid leaching process. Boron rich aggregated cubic boron nitride grinding grits are leached in a mixture of nitric and sulfuric acids, the following conditions being typical; (a) volume ratio of 67% nitric acid to 98% sulfuric acid of 10:20; (b) temperature of 250 DEG  C; and (c) for a time of 1 hour. The process removes sufficient free surface boron to reduce the conductivity at the surface, resulting in an abrasive which does not overplate. FIG. 1 is a photomicrograph of a typical plated surface containing the improved CBN grinding grit of this invention, and FIG. 3 is an X-ray diffraction pattern characteristic of this new product.

Title: Band-dependent switchable vhf mixer circuit arrangement
Inventor: MAIER GERHARD
IPC: H03D/
Filed: 1985-01-16
Granted: 1988-09-01
Abstract: A mixer circuit with a conventional very high frequency circuit for the reception of color television bands I and III, which is connected dependent on the band and which is provided with an NPN transistor. The NPN transistor operates via a collector resistor onto a two circuit band filter. Moiré interferences in the band I region expanded for CATV are avoided by having the mixer current used to 0.3 to 0.6 mA via a counter coupling resistor disposed between base and hot end of the resistor 4. Thus the self-interference in band I is reduced by a value of about 60 dB. In case of band III operation the corresponding switching voltage is fed via a series connection of a diode 6 and a resistor 5 to the base and thus the base level is lifted up to higher mixing current, since in band III self-interferences cannot occur in the case of the presence of signals.

Abstract: An apparatus communicating with data systems, and a method of communicating with data systems. In an apparatus (10, 49) communicating with a high secrecy and high security on-line verification data system (40) and an off-line verification data system (18) of a lower secrecy and security level, a person in possession of a card (21, 22, 12, 24) inputs the card into the apparatus (10, 49). The data are read from the card and input to a security module (50) of the apparatus. On the basis of the data read from the card, the apparatus (10, 49) identifies the card as a card belonging to the on-line data system or the off-line data system. Within the security module (50) of the apparatus (10, 49), a keyboard (46) is arranged, which is adapted to be activated by the person in possession of the card for inputting a personal authentication code (actually a PIN-code) into the security module. Provided the card has been identified as a card belonging to the on-line data system (40), the data read from the card (21) and the code input by means of the keyboard (46) are encrypted by employed an encryption algorithm which is stored in a first storage means of the security module (50) and are output to the on-line data system (40), within which the authenticity of the person in possession of the card is verified. Provided the card has been identified as a card belonging to the data system of lower secrecy and security level (18), the data read from the card (22, 23, 24) are compared to the code input by means of the keyboard (46) by employing a verification algorithm, which is stored in a second storage means of the security module (50), in a comparator of the security module (50). As a result of the comparison within the comparator an authenticity code or, alternatively, a non-authenticity code is output to the off-line data system, exclusively. A coherent set of data and code is under no circumstances output from the apparatus to the data system of lower secrecy and security level. Consequently, the problem of eliminating transparency from the lower level secrecy and security data system to the high secrecy and high security data system is solved.
