IPC: B31B50/16
Filed: 1988-12-21
Abstract: Efficient packaging machines consume a large amount of packaging material. If blanks are produced in the region of the packaging machine by cutting from a web of material wound as a reel, a sufficient quantity of such reels needs to be made available for the packaging machine, specifically for being received by a pivot (16) on the machine side. 
<??>For the efficient, energy-saving provision of reels (12, 13, 14, 15) to the packaging machine, said reels are arranged in large number on a displaceable supporting frame (19) in such a manner that, by guiding the supporting frame (19) to the transversely projecting pivot (16), the respectively front reel (12, 13 ..) can be pushed onto the pivot (16). The pivot (16) can here be moved up and down between a receiving position and a working position. 
<??>The supply of the reels (12, 13  ..) is particularly suitable for the production of blanks of thin cardboard by tearing off from the web of material (10).

Abstract: Cellulose ethers are prepared by reacting in a heterogenous reaction mixture an alkaline solution and an etherifying agent with a fibrous cellulose. The total of the required stoichiometric amount of the alkaline solution and at least a portion of the etherifying agent required in producing the cellulose ether are admixed at sufficiently low temperature to suppress reaction between the alkaline solution and the etherifying agent. The admixture is then contacted with the cellulose fibers, preferably by spraying the admixture thereupon. Additional etherifying agent is then added, if required, to the reaction mixture, and the heterogenous reaction mixture is agitated and reacted at an initial temperature below 40°C, sufficient to produce alkalization of the cellulose. Thereafter the temperature is increased above 40°C to produce etherification of the cellulose and form the cellulose ether.

Abstract: An apparatus which corrects single bit errors and detects double bit errors is presented. The present invention includes an encoder/decoder. During encoding the encoder/decoder produces a plurality of parity bits. These parity bits allow the correction of single bit errors in transmission and the detection of double bit errors in transmission. The encoder/decoder comprises a plurality of arrays. Each array consists of logic gates arranged in the form of a binary tree. Each array generates a single parity bit. Further every array receives as input the same number of data bits; however, each array receives a unique combination of data bits. 
     When the encoder/decoder is used in decoding, the encoder/decoder produces a plurality of syndrome bits. These syndrome bits are used to correct single bit errors in transmission and to detect double bit errors in transmission. When decoding, each array of logic gates within the encoder/decoder produces a single syndrome bit. Each array has as input data bits, as when it is encoding. Additionally each array receives as input one and only one parity bit. The receipt of one and only one parity bit by each array allows for the encoder/decoder to be used both for encoding and decoding. This allows a great reduction in hardware required to implement error correction and detection.

Abstract: An apparatus having a vibratable tip (22) for ultrasonically disintegrating tissue in a surgical procedure and for aspirating the disintegrated tissue and fluid away from the surgical site (12) through an opening (24) in the tip. A connection (42) to the electrosurgical unit provides for delivery of RF cutting current, RF coagulating current or a blend thereof to the tip so that electrosurgical procedures can be conducted separately or simultaneously with ultrasonic aspiration through the tip. It thus is now possible, for example, to electrocauterize simultaneously with ultrasonic fragmentation with a single handheld surgical device. The simultaneous delivery of ultrasonic vibrations and RF current to the tip also has been found to increase the tissue fragementation rate.

The methods involve providing in combination a solid support, which is substantially free of specific binding proteins, and a medium comprising an antigen from the sample and an antibody for the antigen. The combination is incubated under conditions sufficient for the antibody when bound to the antigen to bind to the support. The presence or amount of antibody on the support or in the medium is detemined and is related to the presence of antigen in the sample. The methods have particular application to the detection of gram-negative bacteria.

Abstract: A new process for the synthesis of pangamic acid salts (sometimes also referred to as vitamin B15 and more accurately called dimethylglycyl gluconates). This process consists in the esterification of gluconic acid or of calcium or magnesium gluconate with a dimethylglycine hydrochloride in aqueous medium in the presence of phosphoric acid or of sulphuric acid at a temperature varying between 30 DEG  and 70 DEG C; then in the concentration of the esterification product, followed by removal of the inorganic acids by reaction with a water-insoluble amine of high molecular weight. The pangamic acid obtained is then converted into one of its salts by reaction with a carbonate such as, for example, calcium carbonate or magnesium carbonate. The pangamates are useful in medicine for combating various forms of arteriosclerosis.

IPC: G06Q10/06

Abstract: An information processor (10) for solving assignment problems using a matrix of individual processing cells. The location of each cell within the processor (10) corresponds to the position of the costs in the associated constraint space of the assignment problem, and each cell contains a cost register (12) that is stored with an associated cost value. A noise generator (14) associated with each cell is used to trigger a variable threshold (16) in each cell so that cost values may be transmitted by each cell only when the signal from the noise generator (14) exceeds the threshold. When triggered, the cell disables all other cells along each dimensional axes stemming from that cell from contributing to the current tentative solution. This disabling is removed at the beginning of the next cycle. Successive solutions to the assignment problem are evaluated by adding the cost values in an accumulator (24) for cells that represent each particular solution. The sums are then compared to a criteria by a comparator (28). Thresholds are then lowered by a threshold adjustment circuit (30) for good solutions and raised for bad solutions. This leads the activity of the processor (10) toward a final stable state which corresponds to a near optimal solution of the assignment problem.
