Filed: 1993-02-26
Granted: 1996-11-26
Abstract: A rifle sling for steadying the left arm of the shooter, comprises a length of band or strap material (1) which has an upper arm loop (8) at one end and a hand loop (6) at the other end, said loops being inter-connected by a middle portion. The upper arm loop (8) has a double portion extending between a tightening buckle (2) and an adjustment buckle (3). By using these buckles to adjust the length of the double portion, both the upper arm loop (8) and the middle portion of the sling can be adjusted to fit the shooter. The sling may be worn in a non-operable condition with the upper arm loop (8) tightened around the upper arm of the user and with the hand loop (6) tucked in under the upper arm loop.  When assuming a shooting position, the user loosens the hand loop (6) and puts his four fingers through the loop, thus tensioning the middle portion of the sling and steadying his arm while the fore-end of the gun rests in his palm. Since the sling is at no time attached directly to the gun, the sling is particularly suitable for hunters.

Abstract: The invention relates to a method in the sterilization of the inside layer of a packaging material, the packaging material being produced as a laminate with an inside layer (3) of a transparent thermoplastic which is applied on a reflective material layer (4). The sterilizing energy consists of high energy light flashes emitted from one or more flash units (6), the light flashes being caused to act on the inside (10) of the packaging material for purposes of exterminating bacteria and microorganisms present on the surface (10). Because the sight flashes emitted from the flash unit (6) are reflected by the reflective layer (4), the surface layer (10) of the layer (3) will be influenced by both the direct and the reflecting photoenergy from the flash units (6), the sterilizing effect being thereby improved.

Abstract: An apparatus for transporting sheet-like products includes a belt conveyor with a flexible conveyor belt. The conveyor belt is driven in a conveying direction at a conveying speed. A takeover conveyor has individually controllable clamps which are arranged one behind the other on a carrying member.      The clamps are driven in a rotating direction, and the clamp mouths are directed in the takeover region forward in rotating direction. The products fed to the takeover region are in each case pressed against the conveyor belt by a pressing roller at the free end of the first clamping jaw of the clamp. Since the clamp speed of the clamps is greater than the conveying speed, the following clamp thus catches up with the held product and seizes it at the trailing edge.

Title: Multimedia call configuration system
Inventor: ISIDORO ALESSANDRO LUDOVICO
IPC: H04M3/00
Filed: 1994-06-22
Granted: 1998-08-25
Abstract: An improved system for effecting broadband/multimedia calls and connections within an intelligent switched telecommunication network.  This system, which employs object-oriented commands, is capable of establishing complex call and connection configurations between multiple network subscribers participating in a broadband/multimedia call. These object-oriented commands, which are stored in and initiated from network adjuncts or service control points, eliminate the need for long series of individual low-level commands to be transmitted to the network switching system. Furthermore, the system provides for a finite set of object-oriented commands which are capable of implementing the many complex and diverse interconnections which may be required in effecting multi-party broadband/multimedia calls. This is accomplished by selectively combining various object-oriented commands to produce the connectivity which will support the desired broadband/multimedia call.

Title: Media error code generation as for a video inverse transport processor
Inventor: BRIDGEWATER KEVIN ELLIOTT
IPC: H04N19/89
Filed: 1995-03-30
Granted: 2006-09-19
Abstract: In an inverse transport processor of the type which directs video payloads of a packet signal to buffer memory space, apparatus is included for writing a media error codes at sequential first memory address locations in the memory ahead of each packet payload. Concurrently a processor examines the current packet to determine if it occurs in proper sequence. If a packet is lost, the payload is written to memory in subsequent sequential address locations. If there is no packet loss, the sequential first memory address locations are simply overwritten by the packet payload to excise the undesired media error code. Media error codes can thus be inserted in the packet payload stream without creating timing obstacles, for a system designer.

Abstract: Software rejuvenation techniques which improve reliability of a software system by stopping execution of the system and restarting the execution with "clean" state. The rejuvenation techniques are generally available to applications executing in a computer system. The techniques are implemented using a daemon process which observes applications registered with it and restarts them if they crash or hang and a process like the cron process of the UNIX operating system. The daemon process responds to a rejuvenation specification which indicates that an application which is registerd with it be rejuvenated by making a script for the cron process which specifies that the application's process be killed. When the cron process executes the script and kills the application, the daemon process observes that the application is dead and restarts it. In restarting the application, the daemon process may use state previously saved by the application for that purpose. The specification further contains parameters for the time at which the rejuvenation is to be performed (or the period between rejuvenations), for the manner in which the application is to be rejuvenated, and for operations to be performed when the application is killed.
