Abstract: ABSTRACT           The identification of a mobile radio station in a radio transmission system can be based on a subscriber's number assigned to the mobile radio station which sub-scriber number is registered in, for example, the tele-phone directory and on an identification code which is formed in accordance with a secret enciphering rule from the subscriber number. By copying the identification signal generator, for example, a magnetic card on which the subscriber's number and the identification code are stored, or by listening-in on the exchange of information via the radio transmission channel between a mobile radio station and a stationary radio station (radio exchange) an intended fraudulent user can imitate and use an external identifi-cation.  So as to enable detection of this imitation addi-tional data which change during operation of the mobile radio station are combined with fixed data, which depend on the different procedures in the system (subscriber's number and identification code of the mobile radio station, and are evaluated in the radio exchange.  Such variable data can be constituted by, for example, the number of successful accesses of the mobile radio station to a radio transmission channel. There may be a fixed or a variable relationship between the number of radio messages and the number of fixed data, assigning being time-dependent in the event of a variable assigning, because of the depen-dence on the number of accesses of the mobile radio station onto the radio transmission channel.

Abstract: ABSTRACT    A rotating biological contactor is formed about a polygonal shaft.  The contactor includes a hub formed of a series of hub rings disposed side by side along the length of the shaft with each hub ring formed of hub segments which are joined end to end.  In one embodiment the hub segments are identical and there is one hub segment for each corner of the polygonal shaft.  In a second embodiment there is one hub segment for each two corners.  The hub segments also include a mounting portion which has welded to it alternating flat and formed thin walled sectors of contactor media.  The sectors are joined to each by welding and successive layers of the sectors are angularly offset from each other so that some of the sectors span the joints between adjacent hub segments of a hub ring.

Abstract: The disclosure describes a system for measuring glaze ice, comprising a glaze-ice detector, a device connected to the detector to generate a signal indicating the formation of a specific quantity of glaze ice on the detector, and another device which responds to the signal, and causes sufficient heating of the detector to melt the glaze ice formed on it. The detector is characterized by the fact that it removes the water formed by this melting of the glaze ice before a new quantity of glaze ice has formed on the detector and been detected. An advantage of this system is that it can detect any formation of glaze ice with accuracy and without error.

Abstract: ABSTRACT OF THE DISCLOSURE           The  device  of  the present  invention  is  a compression surface for use with  a peristaltic  pump which   includes   rollers   which   successively   and repetitively  compress  flexible  tubing  in  order  to maintain flow of fluid through flexible tubing.   In order  for  the  flexible  tubing  to  be  compressed,  a surface must be provided against which the rollers may compress the flexible tubing.  The pressure surface of the present invention includes a plate member which has an arcuate surface against which the flexible tubing is compressed.  The plate member is mounted on a pivot so that it may rotate with respect to the peristaltic pump head.   A biasing element holds the plate  member  in operative engagement wiht the flexible tubing when the tubing  is  placed  in  operative  engagement  with  the peristaltic pump head.   In this manner,  the arcuate pressure surface floats on the flexible tubing while, at the same time, exerting a constant force against the flexible tubing for maintaining accuracy of fluid flow.

Abstract: ABSTRACT OF THE DISCLOSURE:    Serving portion sized dietary meat products are produced for quick warm and serve when preserved in frozen pre-cooked condition. They are characterized by an unbreaded surface glazing layer of proteins, spices and flavorings and sugar solids, and devoid of oils and starches to produce a lower calorie product with the characteristics of appearance substantially roasted meat, even when warmed in a micro-wave oven. This is achieved by dry roasting the surface glazing to attain a permanent coloring from its ingredients that also serves to seal in juices and liquid marinade impregnating the meat to avoid dehydration loss when frozen and stored in frozen form.

Abstract: A B S T R A C T            STABILITY TESTING OF SEMICONDUCTOR MEMORIES            Design/test technique to facilitate improved long-term stability testing of static memory arrays with high inherent data retention characteristics at extremely small standby current requirements. The test concept is based on the fact that defects in the standby con-dition system of a memory array have a bearing on the word line standby potential. Detection of word line potentials differing from their nominal value defined for the standby state, i.e. in the unselected operation mode, is accomplished by performing a disturb write operation into the partly or totally unselected array. As a result cells along a defect word line are less disturbed than those along a good one. This (inverted error pattern) is used for screening defect word lines which otherwise would show up as (long-term) data retention problems.

Abstract: TAPE GUIDE MECHANISM FOR DYNAMIC TRACKING CONTROL  ABSTRACT OF THE DISCLOSURE         A tape guide mechanism includes an edge-guide element extending radially from a central axis.  A tape guide roller, rotatable about the central axis, is arranged for urging an advancing magnetic tape laterally in the direction of the edge-guide element, to maintain an edge of the tape perpendicular to and in continuous contact with the edge-guide element during tape transport movement.         A piezoelectric actuator, preferably comprising a stack of flexing type bimorph elements responsive to a voltage signal relating to the direction and magnitude of a tape-tracking error, causes movement of the edge-guide element in a single composite direction having a first component which is perpendicular to the edge of the tape, and a second component, which is parallel to the tape edge.         Thus, the tape is caused to move laterally in either direction for tracking control, in one direction under the influence of perpendicular movement of the edge-guide element toward the tape, and in the opposite direction under the urging of the guide roller, to follow perpendicular movement of the edge-guide element away from the tape.

Abstract: ABSTRACT A bulk feeder for feeding electronic components one at a time into a lead forming machine or the like comprises a hopper and a chute for loading the components into the hopper. The hopper comprises a pair of oppositely disposed side walls, a back wall and a bottom wall.  The side walls are spaced from one another a distance which is slightly greater than the length of the electronic components which are to be fed to the forming machine.  The back wall is downwardly and forwardly inclined and the bottom wall is forwardly and upwardly inclined from the lower end of the back wall. The chute has a slipway channel which is shaped to axially align electronic components with the direction in which they slide down the chute.  The chute also has a discharge end arranged to discharge the axially aligned components laterally of the hopper from a point adjacent a first side wall toward the other side wall so as to strike the other side wall at a point of contact adjacent the back wall such that the component will thereafter slide down the back wall to assume a position extending transversely of the hopper at the lower end of the back wall.  A conveyor is mounted for movement along the bottom wall from the lower end of the back wall to a receiver for components.  The conveyor is adapted to receive the transversely extending body portion of a component located at the lower end of the back wall to transport the components one at a time out of the hopper.
