Title: Optical fiber connector having enhanced provisions for interconnection and for prevention of optical and mechanical disconnection
Inventor: ANDERSON JERRY MAX
IPC: G02B6/38
Filed: 1992-05-13
Granted: 1997-11-11
Abstract: An optical fiber connector which is assembled to a coupling housing by causing only relative linear motion between the connector and the housing and which also includes facilities for preventing optical disconnection from anotherconnector having a portion disposed in the housing includes a cap having two diametrically opposed slots each having an enlarged portion. A barrel is retained within the cap and has mounted thereto a ferrule in which is terminated an end portion of an optical fiber which is to be connected to another optical fiber. The connector is moved to cause the ferrule to enter a sleeve of a housing of a coupling and to cause locking pins of the housing to enter and to be moved along the slots of the cap until each pin is received in an enlarged portion of a slot. A cap extender is connected to an end of the cap and includes an annular detent. A shell which is disposed about and is slidably movable on the cap is moved to cause theannular detent projecting radially from the cap extender to become locked to latching means formed on an inner wall of the shell to lock the shell to the cap and prevent mechanical disconnection of the connector form the coupling mounted in apanel. An annular shoulder on the cap extender limits the travel of the ferrule to prevent optical decoupling from another ferrule in the coupling housing when tensile forces are applied to a cable the optical fiber of which is terminated by the ferrule.

Title: Separating apparatus
Inventor: KUNIG HELMUT
IPC: A22C25/00
Filed: 1992-05-19
Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE:            A device is described relating to separating mixed sub-stances of differing flowabilities, in particular for the purpose of processing foodstuffs.  The processing takes place in a device by which an elastic presser belt is pressed onto the periphery of a hollow separating drum with a perforated wall, so that the substance to be processed consisting of the previously mentioned composi-tion and located between the presser belt and the hollow separating drum is separated into a phase of easily and a phase of less easily flowable components.  The present concept provides for the use of two presser belt systems, which are operative one in series with and down-stream of the other and influence a hollow separating drum, thus offering  the possibility of using presser belts of different softness as well as, in the case of offset arrangement of the presser belt systems, use of varying perforations in the respectively associated cir-cumferential areas.

Granted: 1998-10-20
Abstract: A memory controller which makes maximum use of any processor pipelining and runs a large number of cycles concurrently.  The  memory controller can utilize different speed memory devices and run each memory device at its desired optimal speed.  The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation.  As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication.  The next state machine operates in a similar fashion.  The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks.  The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking.  The memory controller utilizes differing speed memory devices, such as 60 ns and 80 ns, on an individual basis, with each memory device operating at its full designed rate.  The speed of the memory is stored for each 128 kbyte block of memory and used when the memory cycle is occurring to redirect a state machine, accomplishing a timing change of the memory devices.

Title: Method for protecting a volatile file using a single hash
Inventor: FISCHER ADDISON M
IPC: G09C1/00
Filed: 1994-04-06
Granted: 1999-08-24
Abstract: The disclosed methodology permits an insecure computing system to safely perform high security electronic financial transactions. The present invention permits the hash of a file to be taken on an incremental basis. It permits any part of the file to be changed while allowing a new aggregate hash to be computed based on the revised file portion and the prior total hash. The aggregate hash is readily updatable with each record revision without having to recompute the hash of the entire file in accordance with conventional techniques. These objectives using two functions. The first function is an effective one-way hash function "H" for which it is computationally impossible to find two data values that hash to the same result. The second function is a commutative and associative function "F" (and inverse "Finv") and provider a mechanism for combining the aggregate hash and the hash of updated records.      Examples of these latter functions include exclusive OR ("XOR"), and arithmetic addition. The methodology involves combining the hash of each file record and the hash of an identification of the record (i.e., a record number or key). These hashes are combined using a function ("F") whereby individual records may be extracted using the inverse of that function (Finv). In this fashion, an individual record may be extracted from the aggregate hash and updated. With each update, the file hash as computed according to this invention is preferably also written after being encrypted under a key known only to the valid user, or if it is digitally signed by the valid user or if it is held in a tamper resistant storage. Each record is represented by its identification hashed together with its data content. All such record are added together to provide a highly secure integrity check. This aggregate hash reflects the entire database such that the tampering (or rearranging) of any data record is revealed by the use of the record identifier (i.e., record number) in the hash calculation due to its impact on the aggregate hash (e.g., the sum).

Abstract: ABSTRACT    A twin-wire web former in a paper machine, having a single--wire initial portion, after which a twin-wire zone starts in the area of a ribbed deck of a first forming shoe placed inside one of the wire loops.  After the first forming shoe, a pressure-loaded dewatering unit is arranged and which includes opposite sets of ribs and dewatering chambers.  A first dewatering chamber in the dewatering unit is placed above the first forming shoe so as to remove water that drains from the area of the curved ribbed deck of the first forming shoe through its suction-deflector duct.   The first  dewatering  chamber  is  followed  by  a  second  dewatering chamber, whose lower part is connected with a set of dewatering and guide ribs having gap spaces into which a drain duct of the second dewatering chamber opens.  Against the set of dewatering and guide ribs, a set of loading ribs operates, which is placed inside the opposite wire loop and which operates by means of the medium pressure of loading hoses.

Abstract: Vitamin and mineral absorption in warm-blooded animals is promoted by means of a class of vitamin chelates where at least one of the bonds between the metal ion and the vitamin ligand is formed between the ion and an electron rich .pi.-cloud of an aromatic ring of the water soluble vitamin. The chelate, containing a total of from one to three ligands, may contain from one up to three vitamin ligands which form a .pi.-bond with the mineral and, when present, one or two amino acid, dipeptide or tripeptide ligands. The mineral is selected from the group consisting of Fe, Cu, Zn, Mg, Mn and Ca. The water soluble vitamin ligand is preferably a residue of nicotinamide, nicotinic acid, pyridoxine, thiamine, riboflavin and folic acid. The amino acid may be any of the naturally occuring .alpha.-amino acids such as glycine. The .pi.-bond vitamin chelates are absorbed more readily from both the gastric and intestinal areas of the GI tract than vitamins or minerals administered separately or as mixtures.
