Title: Method for reclaiming cured cellular polyurethanes
IPC: C08J11/18
Filed: 1956-02-11
Abstract: A process of utilizing scrap material of the kind produced from liquid reaction mixtures containing active-hydrogen-containing polymeric materials, an organic polyisocyanate and water comprises dissolving the scrap material in at least an equal weight of a liquid or molten active-hydrogen-containing polymeric material at an elevated temperature and forming from the resulting solution further cellular material by reaction with water and an organic polyisocyanate. The expression "active-hydrogen-containing polymeric materials" means polyesters, polyesteramides, polyalkylene ether glycols, and mixtures of two or more of these. Suitable materials are those described in Specifications 694,982, 696,449, 696,450 and 731,071 and in U.S.A. Specification 2,692,873. Suitable polyisocyanates are hexamethylene, m- or p-phenylene, 4,41 - diphenylene, 1,5 - naphthalene, 4,41 - diphenylmethane, tolylene, 4,41-phenylether, 3,31 - dimethyl - 4,41 - diphenyl and 3,31 - dimethoxy - 4,41 - diphenyl diisocyanates 4,41,411 - triphenyl - methane and toluene 2,4,6 - triisocyanates, 4,41 - dimethyldiphenylmethane 2,21,5,51 - tetraisocyanates, and mixtures of polyisocyanates such as those described in U.S.A. Specification 2,683,730. Solution of the scrap material is effected by heating the mixture at temperatures up to 250 DEG C., if desired in vacuo. In examples: (3) and (4) scrap foam material is dissolved by heating to 250 DEG C. under vacuum in a mixture of diethylene glycol/adipic acid and ethylene glycol/propylene glycol/adipic acid hydroxypolyesters. The solution was mixed with polyethylene glycol, a polyoxyethylated vegetable oil (surface-active agent), N-methyl-morpholine, water and a mixture of 2,4- and 2,6-tolylene diisocyanates and poured into a mould to give a foamed product. In a similar example, a diethylene glycol/adipic acid is used alone instead of the mixture of polyesters. The scrap foam material is that obtained by reacting a diethylene glycol/adipic acid hydroxypolyester with a polyethylene glycol, a polyoxyethylated vegetable oil, N-methyl-morpholine, water and mixed 2,4- and 2,6-tolylene diisocyanates.

Title: Process for oxidation of cyclohexane and for the production of adipic acid
IPC: C07C/
Filed: 1960-06-15
Abstract: Adipic acid is made by reacting cyclohexane in the liquid phase with molecular oxygen at a temperature of from 100 DEG C. to 140 DEG C. to oxidize from 5 to 15% of the cyclohexane present and to produce a liquid product comprising cyclohexanol, cyclohexanone and unreacted cyclohexane, separating cyclohexane from the liquid product and reacting the residual liquid with molecular oxygen in the presence of a solvent to produce adipic acid. The first oxidation may be effected in the presence of a metal oxidation catalyst, preferably a cobalt salt soluble in cyclohexane, such as cobalt acetate or naphthenate. Cyclohexane may be present as an initiator. The oxidation can be carried out in a series of reaction zones, preferably four, each equipped with cooling means and agitators and constructed for operation in a pressure range of 100 to 500 p.s.i.g. Cyclohexane is fed in at a space velocity of from 2 to 125 volumes per liquid volume per hour. Air, oxygen or oxygen-enriched air may be employed. The cyclohexane may be removed from the product of the first stage by distillation or other suitable means. The residual oil containing cyclohexanone and cyclohexanol in a weight ratio of 0.9 to 1 or more is a solvent such as acetic, propionic, butyric, iso-butyric or valeric acid and oxidized at a temperature in the range of 70 DEG to 105 DEG C. at pressures between 85 and 400 p.s.i.g. The liquid product is discharged into a crystallization zone to obtain adipic acid crystals which are purified by recrystallization. Specification 941,662 is referred to.
Patent ES-304742-A1 (ES)
Title: Process for the heat treatment of synthetic polymeric films
IPC: B29C48/08
Filed: 1964-10-07
Abstract: An oriented film of a synthetic organic thermoplastic crystallizable polymeric material is heat-treated in a continuous manner to render it substantially sag-free by causing the film to travel around and in contact with the peripheral surface of a first rotating roll which is maintained at a temperature (below the melting point of the film) which would cause the film to shrink laterally in the absence of any lateral restraint, applying lateral restraint to the film over at least part of its travel round the surface of said first roll whereby the width of the film remains constant, then permitting the film to relax by a controlled amount in at least the longitudinal direction by passing it around at least one second heated roll rotating at a peripheral speed less than that of the first roll and quenching the heat-treated film. The term " oriented film " is defined as a film which has been drawn in one direction to induce molecular orientation in that direction or biaxially in the longitudinal and transverse directions simultaneously or in sequence. Lateral restraint may be applied to the film by holding the edges of the film against the roll by means of two elastomeric surfaces moving in the same direction and at the same speed as the film, the surface being spaced apart laterally with respect to the longitudinal axis of the film. They preferably do not have an independent drive and are driven by the roll via the film. The surfaces may be provided by endless rubber belts of Vee or rectangular cross-section travelling around pulleys. Alternatively lateral restraint may be applied to the film by electrically earthing the peripheral surface of the roll and to deposit an electrostatic charge on the surface of the film which does not contact the roll. The charge may be deposited along the edges of the film at least over the initial part of its travel around the roll, or it may be deposited along a line extending across the width of the film at or near the line where the film first contacts the roll. After passing over the roll, the charged surface of the film is discharged by contacting it with earthing means (or causing it to pass very near to earthing means) before passing it to the next stage of the process.

Title: Suspension systems of vehicles
IPC: B60G7/00
Filed: 1967-09-14
Abstract: In a double wishbone vehicle suspension permitting longitudinal flexibility of a wheel relative to a vehicle frame one of the pivots 3 of a wheel carrier 1 acts as a fixed point while the other pivot 2 is adapted to move longitudinally of the frame in a horizontal plane by being mounted at one end 5 of a lever 6 having its opposite end pivoted to a vertical pivot pin 7 rigid with the corresponding wishbone link 4. Pivoting of the lever 6 is resisted resiliently by buffers 10 which are mounted in the lever and engage the walls 11 of the link 4. In modifications (Figs. 4 to 7, not shown) a horizontal pin (16) passes through the buffers 10, which are hollow, a further resilient member (15) being disposed between the lever 6 and pin (16) to control pivoting of the lever about a horizontal axis through the pin 7. The position of the ball joint 26 between the wheel carrier 1 and a steering rod 25 is chosen to give a small vertical component of movement as the carrier 1 and pivot 2 move longitudinally of the vehicle frame (Figs. 11, 12, not shown).

Patent ES-389596-A1 (ES)
Title: Bird swing detector
IPC: G01N21/90
Filed: 1971-03-26
Abstract: Apparatus for inspecting glass containers to determine the presence of the defect termed "bird swing." Containers to be inspected are moved in series on a moving belt conveyor to an inspection position where a rotating multifaceted mirror causes a beam of light to sweep the container sidewall from bottom to top. If no defect is present, the beam of light passes through the container sidewall. A pair of elongated photosensitive elements are positioned adjacent to the container to view the illuminated wall portion of the container at an angle with respect to the direction of the moving light beam. Should a "bird swing" defect be present, the light beam is deflected from its normal position into one or both of the photosensitive elements. The receipt of a signal by one or the other of these photosensitive elements activates a reject circuit which causes the container having the defect to be rejected from the stream of bottles. The reject mechanism takes the form of a stream of high pressure air under the control of a solenoid valve.
Patent ES-400333-A1 (ES)
Title: Electric lamp having a base assembly with integral means for axially-orienting the end contact
IPC: H01K3/16
Filed: 1972-03-02
Abstract: The insulator portion of the base assembly is formed as a separate piece and mechanically locked to the metal shell by providing an inturned peripheral flange on one end of the shell and subsequently rolling a circumferential groove in the side wall of the shell which clamps the rim of the inserted insulator against the flange. The flange defines a transverse reference plane which insures that the axial length of the finished base assembly, and thus the "light-center-length" dimension of the lamp which is fitted with the base, are maintained within prescribed limits. The shell is stamped from sheet metal and the blank which is removed from the bottom wall to form the flanged end of the shell is fashioned into a contact member - preferably a hollow cap that is subsequently force-fitted onto the protruding end of the insulator in clamped engagement with one of the lamp leads during the basing operation and thus serves as the end contact for the finished lamp. The various stamping, rolling and force-fitting operations required to manufacture the base components and then assemble them with the sealed-in lamp are carried out by automated machines and permit the bases to be continously mass-produced without any manual labor. The inner edge of the cap is preferably protectively recessed within an annular channel in the insulator to provide a "tamper-proof" base structure. The use of a preformed insulator which is mechanically locked to the base shell also permits thinner shell material and various plated metals, such as brass-plated steel, to be used - thus further reducing the overall cost of the base and lamp.
