Title: Security cards
Inventor: EASTELL R W
IPC: G11B20/10
Filed: 1976-03-05
Abstract: A method of recording machine-readable security data on a record medium, such as a cash dispenser card, is described in which the security data is deposited on the record medium as a sequence of magnetic characters. The characters may include a first magnetic character which when scanned in a given direction by a magnetic pick-up head having a sensing gap generates a characteristic signal exceeding a first threshold level in a positive direction but not exceeding a second lower threshold level in a negative direction, a second magnetic character which when scanned in the said given direction by a magnetic pick-up head having a sensing gap generates a characteristic signal exceeding the second lower threshold level in a negative direction but not exceeding the first threshold level in a positive direction, and/or a third magnetic character which when scanned in the said given direction generates a characteristic signal exceeding both the first threshold level in a positive direction and the second threshold level in a negative direction. The first and second characters may comprise left-handed and right-handed right-angled triangles respectively and the third character may comprise a rectangle. The invention permits the recording off of any desired binary sequence by arranging that the first character represents a binary "1" and the second character represents a binary "0".
Patent ES-450489-A1 (ES)
Title: Vibratory parts feeder driven by rotating eccentric weights
IPC: B65G27/08
Filed: 1976-08-05
Abstract: A vibratory parts feeder has a feeder bowl with a helical track originating at the bottom of the bowl and extending upwardly along the inner periphery of the bowl wall to an exit station at the top of the bowl. Articles can be progressively fed from the lower portion of the bowl along the helical track to the exit station at a given feed rate by vibratory energy. The feeder bowl and its mounting frame form a feeder bowl mass that is supported above a base mass by a plurality of inclined leaf springs. One end of each spring is connected to the feeder bowl mass and an opposite end of the spring is connected to the base mass. The leaf springs are arranged to move one of the masses vertically in response to rotational twisting of one of the masses relative to the other mass about a central vertical axis of the feeder. A driver that is mounted on one of the masses has a plurality of rotating eccentric weights for imparting to the mass upon which the driver is mounted on oscillating rotational impulses about the central vertical axis of the feeder. These impulses cause the feeder bowl mass to rotationally oscillate about the central vertical axis and to move up and down at accelerations which permit the helical track within the feeder bowl to lose contact on a downstroke with articles being fed along the track. When contact between the track and the articles being fed is resumed on an upstroke, the articles are located in advanced positions along the track due to rotational oscillation of the feeder bowl mass.

Title: Electrical trigger mechanism for firearms
IPC: F41A19/59
Filed: 1977-12-15
Abstract: A hand firearm has a breech block pivotally mounted in the frame so as to be pivotable downwardly from a closed position to a loading position.

Patent ES-478393-A1 (ES)
Title: Improved Deposition Method
IPC: C23C16/54
Filed: 1979-03-07
Abstract: This invention relates to transparent glass window structures of the type bearing a first coating 6 of infra-red reflective material, which is advantageously less than about 0.85 microns in thickness, wherein the observance of iridescence resulting from such a first coating is markedly reduced by the provision of a layer 4 of continuously varying refractive index between the glass 2 and the coating 6, such that the refractive index increases continuously from the glass to the first coating, thereby preventing the observation of iridescence. The coatings are applied by passing the substrate through a reaction zone in parallel with a reactive gas mixture which contains components for forming the two coatings, wherein the reaction to form the first coating proceeds more rapidly. A particular advantage of the invention is its efficacy with clear and lightly tinted glasses wherein the problem of iridescent color has had its greatest commercial impact.
