Abstract: [Abstract]     Steel strip is continuously annealed while suc-cessively travelling through a heating, soaking, primary cooling, overaging and secondary cooling zone in an annealing furnace.  In the overaging zone, an endless steel strip is allowed to run through a passageway that extends spirally from the entry end of the overaging zone to the point where overaging is completed, at a given distance in the direction of radius.  The guide strip travels at the same speed as the steel strip being processed that is delivered from the primary cooling zone.  On the entry side of the overaging zone, the strip being processed is laid over the guide strip so that the two strips spirally travel through the overaging zone side by side.  The processed and guide strips running together are shifted out of the spiral passageway at the point where overaging is completed.  Then, the processed strip is separated from the guide strip by shifting at least one of the two strips.  While the separated processed strip is deliv-ered to the subsequent secondary cooling zone, the guide strip is returned to the entry end of the over-agin zone for the next trip through the spiral passage-way.  Helical devices are used for changing the posi-tion and running direction of the strip being processed Continuous Annealing and the guide strip.  The overaging furnace is annular in shape, provided with a number of radially disposed guide rolls on the inside.  Each guide roll has a plu-rality of guide grooves in which both edges of the guide strip are fitted.     Continuous Annealing

Abstract: ABSTRACT OF THE DISCLOSURE:           A hydraulic percussion mechanism applied mainly for machines with beating-destruction action (rippers-off, chisels, concrete-breakers, etc.) and which may also be used for different types of light and heavy boring hammers.  The present hydraulic percussion mechanism creates simultaneous automatic distribution of the working fluid and provides the necessary decrease of the pressure by using the acquired kinetic energy only for the working stroke of the piston.          It also avoids the necessity of using rubber or plastic cuff gaskets for the tails of the piston.  The advantages of the invention are the following:   the reversion of the distributing bush at the end of the working and the back-ward stroke is impulsive as a result of the movement of the piston,  as the replacement of the bush is achieved at the moment when the respective working chamber is connected to the reservoir and the access of pressure fluid current is cut  off  in time.   This ensures freely and positively reversion of the distributing bush.

Abstract: ABSTRACT    There is a definite need for a functional but inexpensive disposable paint tray liner today to cheaply avoid the time-consuming and messy task of cleaning out a paint tray.  Our disposable film plastic paint tray liner fills this need.  Presently, the only disposable paint tray liner on the market is made of rigid plastic and shaped in the form of an actual paint tray.  The rigid plastic liner resembles a paint tray within a paint tray when in use and retails for approximately fifty cents   This is relatively expensive in comparison to our disposable liner.  Our film plastic paint tray liner, in contrast, is not as bulky as the paint tray in which it is used and can be produced and retailed for a few cents. This lack of bulk also makes our liner very easily disposable.     Our liner also has an important feature that no rigid liner can match.  When paint is being absorbed by the roller, our liner has a slight tendency to adhere to the roller.  This slight adhesion by our liner causes the paint to be more evenly distributed along the roller.  The result is a virtually no-drip roller with excellent paint distribution on the surface being painted (no streaking).     Our liner is also paint-saving in that the paint goes on the roller very evenly and consequontly on the surface being painted very evenly with no excess of paint.     Our liner is also size adaptive.  Even though paint tray manufacturers differ marginally in the size dimensions of their small trays (up to 1/2 inch in length and width), our small tray liner would fit all makes of small trays simply by letting the adhesive strips stick higher or lower onto the paint tray as required for a proper fit.  The overlap and flexibility of our liner enables this possibility.  The rigid liners only fit the paint trays for which they are specifically manufactured.     We regard the feature described in the second paragraph as the paint helping quality of our liner.

Abstract: METHOD AND APPARATUS FOR SIGNED AND UNSIGNED BOUNDS CHECK            Abstract A typical feature of a data processor is a bounds check. A bounds check is achieved when a determination is made as to whether a check value, typically an address or datum, is within predetermined bounds.  Such check values may be signed or unsigned.  By requiring that the upper bound be numerically larger than the lower bound for doing a signed check, and requiring that the upper bound be logically larger than the lower bound for doing an unsigned check, the bounds check is performed by the data processor without the need of receiving a signal which informs the data processor in advance as to whether the check is to be signed or unsigned.

Abstract: ABSTRACT            The circuit of the present invention detects variations of a current IL flowing in a telephone line LL. A low-value resistor r is connected in series with line LL. A constant voltage generator is connected across this resistor. The current Is applied to resistor r by the constant voltage generator varies as a function of IL. This being so, a measurement of the variations of Is will reflect variations of IL and, therefore, can be used to detect both amplitude and directional variations of IL.

Abstract: LOCKUP DETECTION AND RECOVERY IN A PACKET SWITCHING NETWORK Abstract A self-routing packet switching network in which packets are communicated through stages of the network in response to self-contained addresses and in which a packet is discarded if a packet cannot be transferred to a subsequent stage of the network within a predefined amount of time.  In addition, upon a packet being discarded, a maintenance message is transmitted over a maintenance channel to the processor controlling the network.  Each network comprises stages of switching nodes which are responsive to the physical address in a packet to communicate the packet to a designated subsequent node.           The nodes provide for variable packet buffering, packet address rotation techniques, and inter-node and intra-node signaling protocols.  Each node comprises a timer which commences timing for a predefined amount of time upon receipt of a packet.  If the timer times out, the packet is discarded and a maintenance message is transmitted to the processor controlling the network.  The maintenance message includes the physical address plus an address identifying the network entry point of the packet.  By discarding packets after a predefined amount of time, the problem of a self-routing network locking up is avoided when one switching node within the network fails or is experiencing overload traffic conditions.
