Title: Sterile container for medical use
Inventor: POLZER KARLHEINZ
IPC: A61J1/06
Filed: 1983-05-13
Granted: 1988-08-25
Abstract: A sterile container for medicinal purposes is of plastic, esp. a bottle-pack unit, and is designed for metered discharge of liquids. The vessel has a bellows or concertina type body (12) and a discharge pipe (20) with a removable closure cap. This cap. (24) is integrally connected with the discharge pipe (20) and has a lug (24) for handling it. In one embodiment (as shown) the end of the discharge pipe has a weakened zone (28), the cap is sealed to the end of the pipe and it can be broken off at the weakened zone. In the embodiment shown, the discharge pipe tapers towards the cap. In another variant, the inside of the discharge pipe adjacent to the cap has a conical taper in the opposite direction, the cap is screwed onto the end of the pipe and a tapering hollow truncated cone of the cap penetrates into and seals with the internal cone of the pipe. Used in particular for infusion liquids for use in hospitals. The bottle can be made in the usual way for plastic bottles, i.e. blowmoulded, and filled with the infusion liquid at the factory and completely sealed to make it sterile. In use at the bedside, however, the contents do not need to be transferred to a separate bottle, but instead the concertina bottle can be directly connected to a tube and injection needle or catheter.

Title: Error correction method for the transfer of blocks of data bits, a device for performing such a method, a decoder for use with such a method, and a device comprising such a decoder
Inventor: SCHOUHAMER IMMINK KORNELIS ANT
IPC: G11B5/09
Filed: 1983-01-19
Granted: 1989-02-09
Abstract: For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator. Invalid channel words are provided with an invalidity bit in the demodulator. During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways. When too many words of a group of code words are invalid, all words of the relevant group are invalidated. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words.
