Title: Ion exchange materials and their method of preparation
IPC: B01J39/12
Filed: 1965-02-12
Abstract: An ion exchanger which fixes ions of caesium, barium, and rubidium is composed of granular particles of zirconium phosphate containing up to 60% by weight based upon the total weight of the composition of the potassium or ammonium salt of a heteropolyacid, e.g. phosphomolybdic or phosphotungstic acid.

Title: Process of and apparatus for drawing batting
IPC: D04H1/736
Filed: 1967-05-18
Abstract: A method of stretching a fleece uniformly comprises passing resilient needles through the fleece into contact with an abutment, by engagement with which the needles are flexed backwards, the needles while flexed being moved over the abutment and carrying the fleece with them to a point in their travel at which they cease to make contact with the abutment and spring forward dragging fibres with them. Apparatus suitable for carrying out the method comprises resilient needles 4 mounted in a continuously rotating roller 2, the needles being flexed backwards by contact with an abutment in the form of a roller 3 which may be freely rotatable or driven at a slower speed than the roller 2.

In an alternative embodiment, the abutment is in the form of an endless belt and the resilient needles are mounted in an endless belt. In a further embodiment, the needles are mounted in a board which performs a cyclic movement. The stretched fleece thus formed can then be impregnated to form a bonded non-woven fabric.

Title: Light modulation by resonant faraday effect
IPC: G02F1/35
Filed: 1969-05-20
Abstract: The plane of polarization of coherent light from a source 3 is variably rotated by passing the light through an optically resonant medium 5 to cause self induced transparency, i.e. the phenomenon whereby a normally opaque medium becomes transparent to coherent light pulses having an electrical field strength above a threshold value, and causing a varying axial magnetic field to act on the light within the medium by way of an anomalously large Faraday effect. In the preferred embodiment, light pulsed by a modulator 4, e.g. a Pockels cell, and microwave pulses from a generator 2 are supplied synchronously to the medium 5 by means of a master oscillator 1. The group velocity of the microwave pulses is matched to the propagation rate of the light pulses through the medium, e.g. by feeding them to a slow wave helical structure. P.C.M. information is supplied to generator 2 and a polarization analyser may be placed after the medium 5 to intensity modulate the light. The source 3 may be, e.g. a solid state or gas laser, a parametric light oscillator or a giant pulse laser and may produce plane polarized light inherently, e.g. using Brewster windows, or incorporate a polarizing plate. Examples given are of a CO 2 laser with SF 6 as the medium 5, and a ruby laser 3 at liquid nitrogen temperatures with a ruby medium 5 at liquid helium temperatures.

Patent ES-414296-A1 (ES)
Title: Actuator apparatus
IPC: H02N10/00
Filed: 1973-05-02
Abstract: An actuator for converting electrical energy into linear mechanical movement comprises a chamber containing an expandable material and a positive temperature coefficient (PTC) of resistance heater located in thermal communication with the chamber. A first piston transmits force from the expandable material to an external load against the force of a first return spring. The first piston moves out of a casing from a retracted position at a first stop to a protracted position at a second stop at which point continued expansion of the expandable material in one embodiment causes a second piston to separate the chamber from the heat source against the bias of a second return spring. As the chamber separates the thermal resistance between the heat source and the chamber greatly increases until equilibrium is obtained between heat input to the expandable medium and pressure exerted by the medium.

Patent ES-450884-A1 (ES)
Title: Nodularizing treatment employing unitized modifying agent
IPC: B22D2/00
Filed: 1976-08-20
Abstract: A method and apparatus is disclosed for conditioning a charge of molten cast iron, which would normally solidify with a flake graphite structure, to produce partial or total spheroidal graphite cast iron. In addition, the method and apparatus can be used to further condition a partially conditioned cast iron to yield a partial or fully spheroidal graphite cast iron. A recess is provided in the metal flow system (within or without the mold system) leading to the casting cavity or cavities. The recess has a shape and cross-section (taken in directions normal to the direction of flow of the molten charge) such that the spheroidizing agent dissolves uniformly when the molten iron flows over it to achieve unprecedented homogeneity. A dense solid unitary block of spheroidizing or nodularizing agent, substantially devoid of MgO interiorly thereof, is typically snugly fitted in said recess and mates with the side walls and bottom of said recess. The block typically presents a substantially constant and uniform interface with the molten charge during all stages of conditioning and pouring however, a deviation in the interface area may be designed into the block to compensate for molten iron temperature variations or molten iron flow rate variations when the casting technique experiences unusually high variations in the ferrostatic pressure head. A relationship is disclosed between charge weight, charge flow rate, magnesium concentration in the spheroidizing alloy, and interface area so as to determine a desired degree of nodularity in the final casting and/or to design a solution rate compatible with a specific casting technique. The residual magnesium can be reliably maintained at a level sufficient to consistently obtain full spheroidal graphite shape. A preferred magnesium level is 0.020% to 0.040% of the weight of the casting but higher or lower levels can be reliably obtained if required by base metal chemistry. This is significant since the prior art has been unable to reliably obtain full nodularity with 0.02-0.025% residual magnesium under commercial conditions.

Patent ES-462094-A1 (ES)
Title: Disc brake and mounting therefor
IPC: F16D55/224
Filed: 1977-09-02
Abstract: A disc brake includes a frame which carries a pair of friction elements on opposite sides of a rotor. A support fixedly secured to an axle housing cooperates with the frame to permit sliding axial movement and pivoting of the frame relative to the support. A pair of recesses on the support receive flange portions of the frame and form clearances at the connection between the frame and support. Edges on the frame define guides for slidingly carrying the pair of friction elements and recesses on the friction elements fit over the guide for mounting the elements thereon. Moreover, a clearance at the connection between the elements and frame permits the elements to easily slide relative to the frame and pivot relative thereto. A spring member disposed between the support and frame biases the frame to pivot relative to the support to engage the friction elements with the rotor. An adjuster between the frame and one of the friction elements rotate relative to the frame to limit retraction of the friction elements away from the rotor. The spring member includes a portion releasably engaging the adjuster to fix the position of the friction elements relative to the rotor.
