Title: Signature verification system and method of manufacturing a document for an authorized user
Inventor: SZIKLAI GEORGE CLIFFORD
IPC: G07C11/00
Filed: 1979-05-17
Granted: 1985-11-21
Abstract: Signature verification systems are disclosed which include documents each of which bears a cryptographic representation of a function of a position-invariant transform of a reference signature of an authorized user thereof. On some of these documents the cryptographic representation is a digital image of a logarithmic function of the Fourier spectrum of the reference signature displayed as an intensity function the pixels of which have been recollocated in accordance with a cryptokey which is represented on the document. Apparatus (24) are disclosed for use in producing such cryptographic representations on documents. Apparatus (36) are disclosed for verifying documents bearing such cryptographic representations and also bearing specimens of the corresponding reference signatures. Methods of signature verification using documents bearing such cryptographic representations and specimens of said reference signatures are also disclosed.

Title: Continuous-infusion device
Inventor: HESSBERG SIGFRIED
IPC: A61M5/145
Filed: 1980-02-18
Granted: 1983-07-07
Abstract: Disclosed is a portable continuous infusion apparatus for administering an injectable liquid to a patient. The apparatus expells the contents of a syringe on a time controlled basis. It employs two separate springs, with one spring used to power a clockwork and another spring to power a gear rack to advance the syringe plunger or piston. Opening and shutting the apparatus cover automatically winds both springs simultaneously. A safety prevents closing the cover unless the springs are wound. Advancement of the gear rack is adjustable by a control which acts on an escapement lever which regulates an escape wheel. The control moves the escapement lever axially so it can engage a different number of wings on the escape wheel, thereby regulating the incremental advance of the gear rack acting on the syringe plunger.

Title: Process for the removal of cadmium from acid solutions, especially those containing p2o5
Inventor: FRANKENFELD KLAUS DR
IPC: C22B3/28
Filed: 1983-05-13
Granted: 1986-08-21
Abstract: The invention is concerned with a process of removing cadmium from acid, especially P2O5-containing solutions by liquid/liquid extraction with the aid of alkyl amine salts that are dissolved in an inert, organic solvent. The cadmium ions are removed from the acid, aqueous phase and are enriched in the organic phase. The cadmium-containing organic phase, subsequently, is re-extracted with an aqueous salt solution, with the cadmium ions migrating from the organic phase into the aqueous phase. The process is particularly suitable for extracting cadmium from concentrated, highly acid aqueous solutions.

Abstract: This invention relates to a data transmission system in which information data is shuffled and the data service is received by those who paid the charges. According to this data transmission system, a service data and a key code transmitted from a data base station are received by a decoder provided at the side of a subscriber, in which only when these data are decoded and the key code transmitted coincides with a key code at the receiving side, a particular data service transmitted from the data base station can be received by the subscriber. In the data transmission system of the invention, a control data portion transmitted is shuffled by changing a shuffling pattern by a synchronizing code inserted as part of the control data portion and by arranging the code length of the control data portion to be variable so that the content of data can not be decoded easily.
