Patent MX-9701786-A (MX)
Title: Biometric controlled key generation.
Inventor: TOMKO GEORGE J
IPC: G07C9/00
Filed: 1995-09-06
Abstract: A key generation system is implemented as follows. In an enrolment apparatus, a unique number for use with PIN operated machines or public key cryptography system is generated by manipulation of fingerprint information of a subscriber. A filter is then generated which is a function both of the Fourier transform of the subscriber's fingerprint(s) and of the unique number. This filter is stored on a subscriber card. When the subscriber wishes to generate his key, he inputs his card to a card reader of an apparatus and places his finger(s) on a fingerprint input. The apparatus generates an optical Fourier transform from the fingerprint input. The Fourier transform signal is incident on to a spatial light modulator programmed with the filter information from the card. An inverse transform is generated from the filtered signal and this is used to regenerate the key that will be used as the PIN in a PIN operated device, or as the private key in a public key cryptography system.

Title: Implocompressor of dynamic flows.
Inventor: CARLOS ALBERTO BARRERA GARZA
Filed: 1999-11-24
Abstract: There are diverse systems that interact with different types of flows, in some cases they do it in an incomplete way and in other cases they turn out to be many-pieces systems and therefore complicated being disadvantageous. The present invention refers to an imploturbocompressor of dynamic flows, which is a flows interaction system, whose combination of means which form it, allow modifying the flow by means of a single piece of rotatory blades as a system, presented and interacting in a cavity system having its respective inlet ands outlet of flows. This cavity system has in an internal space a semicircular pair shapes joined and connected by its axis; the hollow of this cavity system is disposed so the blade system can rotate in its interior, occupying fully the disposed space for this purpose, which in combination form a part of the state-of-the-art; and when rotating the blade in its interior, it activates the system interacting, modifying and directing totally the flow towards th e center imploding it in the passage cavity where the blade pallets present an Archimedes inclination conducting the flow immediately towards the other side of the system (blade and cavity), wherein the flow changes from a center direction to the outside expanding itself for then continuing its dynamic flow. In the figures it can be seen this invention in diverse perspectives and sections where its internal mechanism is shown as well as graphics where the flow direction is also shown and the blades rotatory direction and its inclination and curvature for the applications as receptor (taking advantage of the flow dynamic) and as flow generator (with a power plant).

Title: Layered Sand - Gravel Screening Device
Inventor: ZHIFENG LI
IPC: B07B1/32
Filed: 2020-01-09
Abstract: A layered sand-gravel screening machine includes a rack body, a screening mechanism, a crank slider mechanism and two spring squeezing mechanisms. A driving motor is fixedly mounted on a receiving frame, and a screening frame is driven by the crank slider mechanism to move in a reciprocating manner. First squeezing springs are mounted between the front ends of sliding rails and the receiving frame. Second squeezing springs are mounted between the receiving frame and the screening frame. Third section squeezing springs are mounted between a support bracket and the tail ends of the sliding rails. The squeezing springs generate a reverse squeezing force under the driving of the crank slider mechanism, so that the receiving frame and the screening frame move fast relatively to screen and separate sand and gravel. The device has the advantages of compact structure, low cost, easy operation and the like, and can greatly reduce the labor and improve the production efficiency.

Each roller is in two or more parts in contact with the work, together with an intermediate part of smaller diameter than the other two. Thus a free space is formed between the innermost portions of the rollers and the work accommodating means for heating and quenching the latter.
