Abstract: A method is indicated for operating a printing press during a trial proof print prior to commencement of the printing run, by means of which method the production of waste paper is reduced to a minimum. For this purpose, the printing image is transferred during the trial proof print to a control cylinder instead of onto a printing carrier. The printing image is subjected to a visual examination in a first circumferential region of the control cylinder, from which examination conclusions can be drawn for the further adjustment of the parameters which influence the quality and position of the printing image. In a second circumferential region of the control cylinder, the printing image is completely deleted again by means of a deletion device, such that a new printing image is available for the visual examination at the next rotation. The printing carrier is introduced into the printing press only after completion of the trial proof print. The method is principally suitable for all printing processes, but is preferably used in offset printing presses. …<IMAGE>…

Abstract: A window VSIS semiconductor laser includes a stimulated region and window regions formed on both ends of the stimulated region. A V-shaped groove is formed in a substrate, and an active layer is formed on the substrate. In one preferred form, the V-shaped groove has a wider width in the stimulated region as compared with the V-shaped groove formed in the window regions. The active layer is a crescent active layer in the stimulated region. One edge of the V-shaped groove in the stimulated region is continuously aligned on a line to the corresponding edge of the V-shaped groove formed in the window regions so as to enhance the optical coupling. In another preferred form, indents are formed in the substrate in the window regions in a manner to sandwich the V-shaped groove formed in the window regions. The V-­shaped groove has the same width in the stimulated region and in the window regions. The active layer is plane shaped in the stimulated region, and a thickness of the active layer in the stimulated region is thicker than the active layer formed in the window regions.

Abstract: A device (10) for dispensing snap-off blades has a compartment (118) for used blade pieces (13) and a slot (46) for use in breaking-off the used pieces (13). The slot (46) leads directly into the compartment (118). In order to prevent the used pieces (13) from falling dangerously out of the slot (46) to the outside, an integral tongue (78) of the device (10) covers the entrance (120) to the slot (46) and has to be pushed resiliently out of the way to insert the used end-piece (13a) to be broken-off. As soon as the end-piece (13a) breaks-off, the tongue (78) springs back to cover the slot entrance (120). The angle (α) of the slot entrance (120) matches the angle (α) of the score-lines (15) on the blade (11), to assist correct location.

Abstract: In a mobile communication system between a mobile station (5) and a telephone network through a base station (4) which assigns a communication channel so that it satisfies required communication quality or D/U ratio, said base station (4) comprises a moving speed detector (22) for measuring moving speed of the mobile station, and a D/U ratio generator (22A) responsive of output of said moving speed detector (22) for providing said required communication quality. The required communication quality depends upon the moving speed of a mobile station, and a communication channel is selected to be the minimum quality channel as far as it satisfies said required communication quality. Thus, the communication quality is always higher than the requested threshold quality level, and the effective reuse of frequencies is improved.

Abstract: A process is provided for making a modified carbon molecular sieve which is suitable for separating gases having different adsorption rates on the sieve. The process involves modifying a starting sieve support having a majority of micropores with an effective pore size of about 4.5 to 8 angstroms, with a two-step process in which the sieve is contacted with two different volatile carbon-containing organic compounds, preferably hydrocarbons, which have different molecular dimensions. The compound used in the first step is larger than that in the second step, so that the pore openings of the micropores of the support are narrowed successively in two distinct steps without filling the micropores themselves. The invention also discloses an improved carbon molecular sieve and the separation of gases, such as oxygen from nitrogen, by the use of this improved adsorbent.

IPC: G06F13/36

Abstract: An IEEE 488 interface couples a microprocessor to one or more devices that are connected to an IEEE 488 bus. Message transmission speed is improved by overlapping a portion of the T1 bus settling time with the microprocessor's write pulse, when it is known that the data on the microprocessor's bus is valid for a predefined period of time before the write pulse's trailing edge. Improved handshake synchronization is achieved by generating an interrupt signal to notify the microprocessor that the last byte of an incoming message has been received. The terminal count signal generated by the microprocessor's DMA controller is used to detect the end of multiple byte messages sent by the microprocessor. The interface automatically generates an EOI signal on the IEEE 488 bus when the last byte of the message is asserted on the IEEE 488 bus data lines. This greatly simplifies the transmission of multiple byte messages by the microprocessor compared with the protocol used by prior art interfaces. The DMA controller's terminal count signal is also used to prevent the loss of data being sent by a device on the IEEE 488 bus to the microprocessor, which typically happens when the microprocessor has to service another device in the midst of receiving a long message from the first device. The loss of data is prevented by detecting a break point in the message transmission, i.e., when the DMA terminal count signal becomes active, and then holding off the first device from asserting "data valid".
