Title: Device for detecting magnetic fields and method of making same
IPC: G06K7/08
Filed: 1978-06-02
Abstract: Fringing magnetic fields established by magnetic bars having parallel longitudinal axes are read from documents, such as checks, to determine a code on the document. The fringing fields extend in opposite directions to indicate the code. An array of magnetoresistive elements responsive to a DC energizing current is included so that at least one of the elements is provided for each of the fields. An alternating magnetic field of predetermined frequency and phase is coupled to each of the elements by a conductor that is effectively a single turn coil. The alternating magnetic field is superimposed on the fringing field so that the two fields are combined in each element to modulate the DC energizing current. The predetermined phase is compared with the phase of the modulated current to provide an indication of the fringing field direction and of the code. The conductors and elements are mounted in registration on a dielectric substrate, so that each substrate is effectively a plane of a three-dimensional matrix including a multiplicity of substrate planes.

Title: A composition containing a dispensible material,a method of dispensing a material onto a surface and a system for dispensing the composition.
IPC: B01F23/00
Filed: 1980-04-12
Abstract: A water-in-air emulsion or suspension containing a dispensible material is formed by stabilization of small droplets of aqueous liquid with an interfacial barrier of very fine, hydrophobic metal oxide particles such as silane modified silica. As the droplets are subjected to shear such as during passage through an orifice, the shear forces experienced partially destabilize the barrier allowing the droplets to coalesce to form particles of controlled density and increased size. At least 10% of the droplets coalesce into particles after leaving the orifice. Active ingredients such as antiperspirants may be added to either the aqueous liquid phase or to the powder phase as long as they do not destabilize the suspension. A non-pressurized system comprises a container suitable for dispensing the suspension having a compartment receiving the suspension, a valve having an outlet orifice of a dimension adapted to impart a preselected shear and destabilization to the suspension and the container being adapted to enable the suspension to be propelled through the outlet orifice.

Patent ES-8307373-A1 (ES)
Title: Sliding weight scale
IPC: G01G1/36
Filed: 1982-05-26
Abstract: A sliding weight scale includes a recirculating ball spindle mounted in a balance beam arranged to pivot about a swivel axis. The spindle extends perpendicularly of the swivel axis. A sliding weight is engaged via a nut with the spindle. A gear wheel is fixed to the spindle and is driven by another gear wheel fixed on the base plate of the scale. A hand wheel drives an intermediate gear assembly which, in turn, drives the gear wheels and the spindle. The gear wheels driving the spindle are located in a vertical plane containing the swivel axis of the balance beam. By the use of the recirculating ball spindle, the displacement forces acting on the sliding weight are kept small so that dimensional variations occurring in manufacturing and assembly have a negligible effect on the weighing accuracy of the scale.

Title: Method of controlling horizontal motion of a load application point on an articulated crane
IPC: B66C23/52
Filed: 1983-04-05
Abstract: A method and apparatus for controlling the horizontal motion of a double articulated crane comprises determining the angle about a common axis between a base member pivotally mounted on a crane post and a head member carrying a load application point on an outer end thereof. The angle can vary from 0 DEG to 360 DEG . A desired movement direction value is then set on a direction selector movable on a direction indicator. The value corresponds to a target position for the load application point. The desired movement direction value is adjusted by small increments to reach the target however. The desired movement direction value is broken up into two components, one aligned with the axis of the head and the other aligned with a perpendicular axis. The values of these two compartments are calculated as a function of the sin or cos of an angle of misalignment between the longitudinal axis and the direction of the selector. The pivotal speed of the base member about the crane post and the head member about the common axis between the base and the head members is then calculated and utilized to drive the equipment for rotating the members.
