Abstract: 2.1. Packages composed of two sub-packages are in increasing demand as so-called cigarette cartons, as "half cartons", i.e. sub-packages with a smaller number of packets of cigarettes, are demanded by consumers. The sub-packages are produced from a common, integral blank, which is severed before the package is brought into circulation, so that sub-packages are formed from two partblanks. The said sub-packages are connected to one another by means of separable connecting elements, especially adhesive strips. 2.2. Such packages, which comprise two sub-packages, are mechanically produced in an efficient manner in a folding revolver. An integral blank is introduced into pockets of the folding revolver and is virtually completely folded. The groups of packets of cigarettes are then pushed into the sub-packages inside the pockets via open sides.

Abstract: An apparatus and method to facilitate the  in situ  detection of small leaks in fluid-filled, capacitive type pressure transducers by remotely and non-intrusively inducing a brief time varying transient signal, and then analyzing the frequency response of the transducer to such excitation in order to detect the presence and effects of a fluid leak. The adverse effect of this induced transient signal on the process control circuitry is insignificant, while providing for an accurate and sensitive method for detecting the extent of fluid loss in the transducer when evaluated according to the present invention. As a consequence of such transducer evaluation techniques, frequency responsive characteristics of such devices may be recorded and self-correlated over long periods of time. Such self-correlation provides an accurate, transducer-specific historical profile which may be used as a means for detecting malfunction anomalies in the output of the pressure sensing transducer device and predicting when the device will fail due to loss of internal dielectric fluid.

Abstract: A defibrillator/monitor (10) is disclosed employing a message processing routine (60) that controls the way in which information from a plurality of sensing circuits (28) is communicated to an attending physician by output devices (30). In that regard, each of the various conditions monitored by the sensing circuits has a priority associated therewith. Each condition may be associated with one or more of five different types of messages: an initial display message, steady state display message, initial sound message, steady state sound message, and display icon message. The different messages, like the different conditions, may also be prioritized. The particular message or messages produced by the output devices in response to a particular set of conditions is then dependent upon the relative prioritization of the conditions and messages as evaluated by a microcomputer (18) in accordance with the routine.

Abstract: An apparatus and a technique for determining body ply cord distribution in a calendered fabric sheet. Test strips are cut from the sheet and formed in a roll with the cords extending parallel to the axis of the roll and normal to the end thereof. The end of the roll is then exposed to polarized light, accentuating light intensity differences between the cross sectional area of the cut cords and the elastomeric material in which they are embedded. A digitized image of the spiral end of the roll is generated and the resulting pixels are analyzed to determine the locations of the center points of each of the cords. Finally, the distances separating the center points of adjacent cords are determined and, if they fall above or below predetermined thresholds, a determination is made that the calendered fabric sheet is not acceptable for forming body plies.

Abstract: The invention relates to a process for coating red-luminescing phosphor particles with haematite ( alpha -Fe2O3) by first applying Fe(OH)3 to the phosphor particles and then converting it at elevated temperature into  alpha -Fe2O3. Good adhesion of the haematite pigments on the phosphor particles is made possible by first preparing an aqueous solution of an iron(III) salt and of a complexing agent, said complexing agent and its concentration being chosen so that it combines with Fe<3+> ions to form complexes which, on the one hand, do not precipitate at a pH which is at least 0.5 greater than the pH at which the phosphor particles are just no longer chemically attacked, and which are separable on further increases in the pH, so that Fe(OH)3 is formed, and thereafter, if the pH is still not sufficiently high, adding a base in an amount such that the pH is raised to a value which is at least 0.5 less than the value at which Fe(OH)3 starts to precipitate and which is at least 0.5 greater than the value at which the phosphor particles are just no longer chemically attacked, thereafter stirring the phosphor particles in, adding at any time a compound which decomposes on the temperature being increased and on decomposition acts like a base, and thereafter slowly raising the temperature of the suspension, whereby the phosphor particles are covered with Fe(OH)3 by homogeneous precipitation.

Abstract: A method and a device for blowing conveyor pipelines (3) free are proposed, in which there is no longer any need for an additional blower for blowing the pipeline (3) free, for example during cleaning. For this purpose, the high pressure of the compressor (1), which is available as conveying pressure during the conveyance of bulk materials, is used as a driving pressure for sucking in additional gas, for example air, via an injector (7) while the pipeline (3) is being blown free. The volumetric gas flow available for blowing free thereby becomes greater than the compressed-air flow generated by the compressor (1), the pressure being reduced at the same time. <IMAGE>

Abstract: A proactive threshold secret sharing cryptosystem using a set 
of servers. The cryptosystem is a  threshold  cryptosystem, 
in the sense that service is maintained if at least ( k  + 1) 
out of  n  servers are active and honest. The secret signature 
key is compromised only if the adversary breaks into at least 
( k  + 1) servers. It is  robust  in the sense that the honest 
servers detect faulty ones and the service is not disrupted. 
It is  recoverable , because if the adversary erases all the 
local information on the server it compromised, the 
information can be restored as soon as the server comes back 
to performing the correct protocol. The method and system has 
proactiveness, which means that in order to learn the secret, 
the adversary has to break into ( k  + 1) servers during the 
same  round  of the algorithm because the shares of the secret 
are periodically redistributed and rerandomized. The present 
invention uses a verifiable secret sharing mechanism to get 
the security requirements during the update between two 
rounds. The security of the scheme depends on the assumption 
of intractability of computing logarithms in a field of a big 
prime order and the ElGamal signature scheme.

Abstract: A bearing or bushing (150) for supporting a rotating shaft (not shown) in a thin walled frame (140) of an electrophotographic printing machine. The composite bearing has a flange (152) at one end and is adapted to be inserted in an opening (142) in a wall (140) until the flange (152) abuts the surface of the wall. A protruding tab (154) formed by displacing a small portion of the flange (152) extends in an axial direction and cooperates with a corresponding opening (146) in the wall to prevent rotation of the bearing (150) relative to the wall (140). The protruding tab prevents the bearing from rotating about its axis (144) which can cause the bearing to be worn on the exterior surface by rotational contact with the wall (140). In another embodiment, the protruding tab (164; Figs. 3,4) comprises a projection formed integrally with the flange. A snap ring (176) is attached to the bearing (150), by slotting into a groove (158), on the side of the wall opposite the flange, and prevents axial movement of the bearing. In another embodiment, a push nut (170; Fig. 2B), which frictionally engages the outer surface of the bearing (150), is used to prevent axial movement thereof.

Abstract: A weighted wavelet hierarchical vector quantization (WWHVQ) procedure is initiated by obtaining (12) an N x N pixel image where 8 bits per pixel. A look-up operation (14) is performed to obtain data representing a discrete wavelet transform (DWT) followed by a quantization of the data. Upon completion of the look-up, a data compression will have been performed. Further stages and look-up will result in further compression of the data, i.e., 4:1, 8:1, 16:1, 32:1, 64:1,...etc. Accordingly, a determination (16) is made whether the compression is complete. If the compression is incomplete, further look-up is performed. If the compression is complete, however, the compressed data is transmitted (18). Optionally, it is determined (19) at a gateway whether further compression is required. If so, transcoding is performed (20). The receiver receives (22) the compressed data. Subsequently, a second look-up operation (24) is performed to obtain data representing an inverse discrete wavelet transform of the decompressed data. After one iteration,the data is decompressed by a factor of two. Further iterations allows for further decompression of the data. Accordingly, a determination (26) is made whether decompression is complete. If the decompression is in incomplete, further look-ups are performed, elsethe procedure is ended.
