Patent EP-0106873-B1 (EP)
IPC: H01M50/528
Filed: 1983-04-22
Granted: 1986-01-29
Abstract: Magnetic polymer particles prepared by treating compact or porous polymer particles with a solution of iron salts and , if desired, salts of other metals which are capable of forming magnetic ferrites, in which the solution swells or penetrates into the particles. Iron hydroxide and possible other metal hydroxides are precipitated for instance by raising the pH value, and the particles are optionally heated. In the iron salts used the ratio between di- and trivalent iron is suitably such that magnetic iron oxide is formed directly. It is also possible to use oxidizing or reducing groups or additives to obtain such a ratio. When other metal salts are used in addition to iron salts, the operation is carried out in the same manner. For instance, when Mn++, Co++ or Ni++ salts are used in addition to Fe++ salts, the divalent iron is oxidized to trivalent so that magnetic ferrite is obtained. The polymer particles which are treated with metal salts preferably contain metal-binding groups. Such groups are incorporated for instance by using monomers which contain said groups for the preparation of the polymer particles, or the groups are incorporated in the polymer particles prepared. The magnetic polymer particles are spherical and have a uniform concentration of magnetic material. They may be used for medical, diagnostic or other purposes.

Title: Coin testing apparatus
IPC: G07F1/04
Filed: 1984-07-26
Granted: 1990-05-16
Abstract: @ A coin testing apparatus subjects a coin inserted into a coin entry (1) and rolling down an inclined track (2) to testing at a testing station (3) comprising sensors (4,5,6) which may for example be inductive sensors. If a coin is found to be acceptable an accept signal is generated and this causes gate mechanism (8) to open to permit the coin to access accept path (9), the gate mechanism (8) being normally closed so that unacceptable coins can only access a reject path (10). A post-gate detector (11) in the accept path (9) senses the passage of an accepted coin and serves to close the gate mechanism (8) and also to determine allocation of a customer credit. A pre-gate detector (12) upstream of the gate mechanism (8) has its output logically processed with the accept signal produced when an acceptable coin is tested and/or with the output of the post-gate detector (11).

IPC: B23D21/14
Filed: 1986-06-16
Granted: 1992-02-12
Abstract: An apparatus for cutting hollow, metal, spirally formed pipes is disclosed. The apparatus uses two passive, rotatable knife blades to cut the pipe. An upper knife blade is positioned inside the pipe so that its cutting edge is adjacent to the inner pipe surface. A lower knife blade is positioned outside of the pipe so that its cutting edge is adjacent to the cutting edge of the upper knife blade in the lateral direction, but is clear of the pipe and upper knife blade in the longitudinal direction. To cut the pipe the lower knife blade is raised until its cutting edge overlaps the cutting edge of the upper knife blade. The knife blades then puncture the pipe. The pipe is rotated through the overlapping blades to completely cut the pipe. Since the pipe moves spirally (i.e., it moves forward while it rotates), the knife blades are adapted to move in the direction of the pipe during the cutting process. This permits the overlapping knife blades to cut the pipe rectangularly. The upper knife blade is attached to a cantilevered boom, and the lower knife blade is attached to a knife holder and a vertical raising device. These components are all attached to sliding guide rails so that they move with the cutting blades in the direction of the moving pipe during the cutting process.

Abstract: Operator-interactive verification of a card-based transaction involves reading a magnetic stripe (24) on the card (C) to derive test data (T) representing an arithmetical combination of a uniqueness characteristic of the card (derived from its translucency at defined locations D1-D6) and the assigned-user's personal-identification data (PIN). The test data (T) is arithmetically-combined with the personal-identification data (PIN) entered by the user, to produce a decoded representation of the uniqueness characteristic (D min ) which is compared with a fresh sensing (D) of that characteristic as a basis for verification of both the card (C) and the user-entered data (PIN). The user can choose to alter his operative personal-identification data (PIN), and does this, after first achieving verification using the exisiting data, by entering the new, chosen data for re-calculation with the decoded uniqueness characteristic (D min ) to produce new test data (T min ) which is then recorded on the card (C) in place of the old (T).

Title: Submarine flare
IPC: F42B4/26
Filed: 1987-08-21
Granted: 1992-08-05
Abstract: A flare (1) for submarine use. The flare (1) is caused to be deployed from a submarine location where it will rise to the surface of the water because of its buoyant casing. A hydrostatic valve means (147) is provided within the casing and it opens when the flare is at or near the surface of the water to render said flare ready to project a flare composition (5) into the air. The hydrostatic valve means (147) is held inoperative by a latch mechanism (51) which is tripped as the flare is deployed from a firing tube at the submarine location. The flare composition (5) cannot be projected into the air until the flare (1) is within a range of vertical attitude determined by inclination means (13). The flare composition (5) cannot be projected into the air until the nose is above water. The flare (1) thus has a sensor (23) at its forward nose to determine that the nose is above the water. A time delay means (87) is provided which is initiated by a pyrotechnic medium (85) used to project the flare composition (5) into the air, to delay ignition of the flare composition (5) until it has at leastcleared the surface of the water.
