Title: Public chain-based token exchange method and blockchain system
Inventor: JIE BAI
IPC: G06Q20/38
Filed: 2019-12-03
Abstract: This disclosure provides a public chain-based token exchange method and blockchain system. According to the method, in actual applications, by means of initiating the supply 5 transaction to the public chain, a plurality of supply chains exchange the respective supply tokens provided thereby for the public chain tokens having an equal value; the public chain stores various supply tokens transferred by the supply chain and records the supply quantities; the exchange chain initiates the exchange transaction to the public chain, so that the public chain calculates the exchange rate based on the supply quantities of the initial 10 tokens and the exchange tokens that are specified in the exchange transaction, and subsequently extracts, from the stored supply tokens, the exchange tokens haivng an equal value to the initial tokens and transfers the exchange tokens to the exchange chain. By means of calculating the exchange rates between different types of tokens by using the public chain, the method may provide an objective and reasonable exchange environment. 15 Moreover, after the supply transaction takes place, the public chain stores the supply tokens so that the exchange chain performs the exchange transaction with the public chain only when performing the transaction, without contacting the exchange counterparty, thus preventing a centralized program from participating in. In this way, the exchange efficiency is improved. 20

Patent NL-8304214-A (NL)
IPC: G11B20/18
Filed: 1983-12-07
Abstract: The values of incorrect samples of, for example, a digital audio signal are estimated by means of interpolation. For this purpose an appropriate sampling interval is determined from the number of incorrect samples, in which interval the incorrect samples are situated. Subsequently, a best-fitting recursion formula is determined from the values of the samples, a first estimate being taken for the values of the incorrect samples. By means of this recursion formula the value of a sample is expressed as a weighted sum of the values of a number of preceding samples and an error term. By means of the recursion formula thus found the values of the incorrect samples are subsequently estimated, in such a manner that they are best-fitting values for the recursion formula. The Application also discloses a device for carrying out the method.

Patent NL-9200484-A (NL)
Title: Drill head
IPC: B23B29/034
Filed: 1992-03-16
Abstract: The invention involves a cutter head for metal working machines (metal machining equipment), in which the tool is secured in a separate tool holder (chuck) so that rapid changes and fine adjustments of hole diameters are possible by stepwise rotation of the cutter head with respect to the machine tool holder. The advantage of this system over previously known cutter-head systems is the option of pre-setting boring cutters. The present system further differs from other systems in terms of the positioning of the boring cutter; by virtue of a combination of force and positive locking it is possible for the boring cutter to be positioned accurately reproducibly in the machine tool holder. The cutter head is composed of three sections, namely: the machine tool holder with fine adjustment and the replaceable cutter head tool holder which determines the nominal hole diameter.
