    Abstract: A process for conditioning pigments which comprises grinding a crude copper phthalocyanine pigment and a crystallizing solvent in the absence of inorganic salt but in the presence of one or more sulphonated phthalocyanine amine derivative having the general formula ##STR1## wherein Pc is a phthalocyanine, R.sup.1, R.sup.3 and R.sup.4 are hydrogen or a hydrocarbon residue, R.sup.2 is a hydrocarbon residue, p is 0 to 3, q is 1 to 4, and the sum of p and q is 1 to 4, the resulting pigment composition is freely dischargeable from the mill in high yield and is, moreover largely in the .beta.-form.

    Abstract: A system for the authentication by a card-issuing financial institution of identifying information of a card-holding user of a public data network. The system includes a secure data entry device connected to the public data network and a gateway device connected to the public data network and to a private data network used for transmitting messages between financial institutions. The secure data entry device enables the user to enter identifying information of a card issued by the card-issuing financial institution, and transmits the identifying information in a secure manner over the public data network to the gateway device. The gateway device transmits the identifying information to the card-issuing financial institution and receives an approval response from the card-issuing financial institution over the private data network. The approval response provides authentication of the identifying information by the card-issuing financial institution.

    Abstract translation: 用于由发卡金融机构认证的用于识别公共数据网络的持卡用户的信息的系统。 该系统包括连接到公共数据网络的安全数据输入设备和连接到公共数据网络的网关设备和用于在金融机构之间传送消息的专用数据网络。 安全数据输入装置使得用户能够输入由发卡金融机构发行的卡的识别信息，并且通过公共数据网络以安全的方式将识别信息发送到网关装置。 网关设备将识别信息发送给发卡金融机构，并通过专用数据网络从发卡金融机构接收到批准响应。 批准响应提供发卡金融机构对识别信息的认证。

    Abstract: A keypad is disclosed which has a plurality of keys (12) for the input of information. Each key has a first switch (80) and a second switch (90). The first switches (80) are all connected to a common electrical interconnection (120) and the second switches (90) are connected into a matrix electrical interconnection (62, 100). The microprocessor (66) detects a global signal on the common interconnection (120) and supplies scan signals to the matrix interconnection (62, 100) to enable detection of a particular key. The processor (66) may also selectively change the state of lines (62, 100) of the matrix and also maintain particular lines in a predetermined state by open drain ports of the processor to which the lines of the matrix are connected.
