Granted: 1990-06-19
Abstract: BARREL SHIFTER ABSTRACT OF THE DISCLOSURE A barrel shifter including a first bit reverse unit which reverses the bit position of all bits of input data or passes the bit positions to leave them as they are; a bit shift unit which shifts output bits from the first bit reverse unit in one fixed direction by exactly the number of bits to be shifted; and a second bit reverse unit which reverses the bit position of all bits of input data or passes the bit positions to leave them as they are, to produce the desired output data. Thus, even if there is an increase of the number of bits of the input data, the hardware structure and control do not become complicated and the use of ICs is made easy.

Abstract: ABSTRACT OF THE DISCLOSURE   During a tool change, the template is to be moved dimensionally accurately into the idling stage of a transfer press and out of the same on support elements at the sliding table in the tool space of the transfer press.  This requires a dimensionally accurate coupling. A gripping and holding device is provided in the idling stage for the insertion and retraction of a mounting bolt into a, respectively, out of a mounting bushing.  The mounting bushing is thereby rotatably supported at the template and forms, on the one hand, a first bayonet-like connection by means of the mounting bolt, a guide groove machined into the same and a cylindrical pin engaging into this guide groove and, on the other, a second bayonet-like connection by means of a retaining plate, a cylindrical pin provided in the same and a mounting groove machined into the mounting bushing.  These connections operate one after the other by rotation of the mounting bolt by means of an adjusting means.  The arrangement can be used in a transfer press with an idling stage between press columns.

Title: Controlled use of cryptographic keys via generating station establishedcontrol values
Inventor: MATYAS STEPHEN M JR
IPC: H04L9/08
Filed: 1988-05-12
Granted: 1991-12-03
Abstract: ABSTRACT OF THE DISCLOSURE    A method for controlling the use of a cryptographic key at a using station by a generating station in a network of generating and using stations is disclosed.  A control value specifying the use of the cryptographic key is transmitted with a generated cryptographic key to at least two designated using stations one of which may be the generating station.  Each of the generating and using stations have cryptographic facilities that securely store a master key.  Two techniques are described for controlling the use of the cryptographic key.  In the first, the key and the control value are authenticated via a special authentication code before use by the using station.  In the second, the key and control value are coupled during key generation such that the key is recovered only if a correct control value is specified.  In addition, two techniques are described for controlling who may use the cryptographic key.  In the first, each using station has a unique secret transport key shared with the generating station which generates the key in such a way that it can be recovered or regenerated only by the designated using station possessing the correct secret transport key.  In the second, secret transport keys are shared by pairs of using stations and cryptographic separation is achieved by using public or nonsecret values unique to each using station.

Abstract: ABSTRACT      A mechanism for mounting and removing a blade having an elongated slot mounting means from a blade handle which has a mounting boss for insertion into the elongated slot.  The mechanism includes a handle guide forming one side of a passageway for insertion of the handle therethrough, the handle guide having a flexible body which is sufficiently flexible to allow deflection of the handle for withdrawal of the boss out of mating relationship with the elongated slot.  The mechanism further includes blade extracting means fixed opposite the handle guide forming a second side of the passageway and having a blade retaining projection arranged adjacent the passageway which can be actuated to prevent withdrawal of a blade from the passageway.  Finally, an actuation means is included which is fixed for actuation of the blade extracting means upon deflection of the handle sufficient to disengage the boss from mating relationship with the elongated slot so that a blade mounted on the handle can be removed therefrom when the handle is withdrawn from the passageway. The present invention also includes a device including such mechanism in combination with a blade retaining and/or disposal well which can serve as a blade dispenser and/or disposal device.

Abstract: Abstract A container for controlled release of a preferably liquid medium,  such as a liquid detergent,  comprising a cup (1) and a dosage insert (2) connected to said cup. The cup is provided with an  inwardly  directed  flange  part  (4)  for forming a cup opening (3), and the dosage insert (2) com-prises a flange-like counterpart (8)  abutting the flange part (4) of the cup (1) and, while forming an opening (13), extending substantially complementary to said flange part (4)  in the direction towards the inside  (14)  of the cup (1).   The  insert  (2)  comprises furthermore a locking and dosage part (15), said part being able to occupy two stable positions in relation to the counterpart (8), and having a number of shovel-shaped blades (17) connected to the inner rim (16) of the counterpart (8) via thin-walled areas (18) acting as hinges  Said blades abut with their upper terminal surfaces (19) the inner surface (20) of the flange part (4) of the cup (1) in a locked position and extending conver-gingly from salt upper terminal surfaces (19) into the inside (14) of the cup (1), where they are connected to a connection body (22) via thin-walled areas (21) acting as hinges.  Thus a very secure and reliable connection between the insert and the cup is obtained, since in its locked position the locking and dosage part of the insert presses    the counterpart against the flange part of the cup and is itself situated in the inside of the cup so that it cannot from outside be forced to leave this locked position. At the same time the locking and dosage part causes a controlled release of de-tergent, since its shovel-shaped blades obstruct the inflow of water into the inside of the container as well as the outflow of detergent from the container.

The operator is variably display instructed to place these removed documents either face up in the stacking tray, or face down in the seperate document input, depending on the jam detection position and document removal position and copier operating condition, and the copier is restarted for job completion without manual document reordering.
