Title: Polyurethane foams containing reactive fibers and process for their manufacture
IPC: C08G18/62
Filed: 1977-02-11
Abstract: Fiber-containing polyurethane foams having improved compression properties, especially at deformations of greater than 50%, are obtained by incorporating in the foam-forming composition from 0.1 to 10% by weight, based on the weight of finished foam, of polyolefin fibers, e.g., polyethylene or polypropylene fibers, that have been treated to provide them with functional groups that are reactive with isocyanates. The reactive fibers may be obtained by fixing to the fiber surface or incorporating in the fiber polyfunctional compounds, e.g., starch, methylcellulose, carboxy methylcellulose, saccharin, polyglycols, polyvinyl alcohol, hydroxyl-group-containing block copolymers, completely saponified copolymers of ethylene and vinylacetate and oxidation products of a polyolefin.

Title: Internal combustion engine
IPC: F02B31/00
Filed: 1977-05-10
Abstract: An internal combustion engine comprising a combustion chamber, an injection chamber connected thereto through an injection port, a secondary inlet passage opening to the injection chamber, and a secondary inlet valve for opening and closing the secondary inlet passage. A spark plug is extended into the combustion chamber so as to dispose a spark gap of the plug close to the injection port. At the suction stroke of the engine, air in the injection chamber is injected near to the spark gap through the injection port to blow away the combustion gas around the gap and also to generate a strong swirl and turbulence of the mixture in the combustion chamber, thereby improving firing and combustion of the lean mixture in the combustion chamber to reduce the discharge of noxious components in the exhaust gas and improve the fuel consumption.

Title: Drum-type screening machine
IPC: B07B1/20
Filed: 1978-01-30
Abstract: A drum type screening machine has a centrifuging rotor within it. A perforated retaining element is carried by the shaft between a feed inlet and an entry region of the drum. The perforations of the retaining element are small enough to retain the foreign bodies which it is intended to retain but larger than the perforations of the screen. The retaining element has an access aperture, a closure element and means for holding the closure element movably in position to close the aperture. The retaining element can be a basket made up of a perforate plate with a perforate rearward flange. The closure element can be a half-moon segment, located by locating pins and rotatable on the shaft with respect to the remainder of the retaining element on clearing the locating means when pressed axially against the force of a bias spring. Use of the retaining element prolongs the screen life so much that tension adjustment become necessary. Provision is made for this to be done from outside of the machine. The screening drum has a pair of rings which support the screening cloth and which are held apart at an adjustable distance by tensioning bars. One ring is supported within an end member of the machine housing and the other on support means within the housing. Each bar is externally threaded, e.g. by way of an extension sleeve that is axially fast with the bar. The sleeve is engaged by an internally threaded nut which is axially fast with the end member of the machine. The sleeve extends through that nut and through the end member to the outside of the machine. A hexagonal head formed on the end of the sleeve can be turned exteriorly of the machine with a box spanner, thereby to tension the screen cloth.

Title: Metallized film capacitor and method of manufacture
IPC: H01G4/012
Filed: 1980-09-25
Abstract: In wound metallized capacitors because of wide metallized margins and misregistration during winding wide metallized foils are necessary. The disclosed device reduces the use of wider foils by using a particular metallizing pattern and thus reduces the size of the capacitor for a given capacitive rating. A rolled metallized film capacitor is manufactured completely metallizing one surface of each of a pair of dielectric films (31, 32) and advancing the film while laser scribing patterns demetallized lines (34, 35) on the respective films which are wound together to provide a pair of capacitor plates of finite areas. The laser scribing (111, 112 128, 129) is controlled so that when the films (31, 32) are wound together, the lines on the respective films are in overlaying relationship on the core and peripheral windings, and are diverted to opposed marginal edge portions on the respective films on the intervening windings.

Patent ES-8203545-A1 (ES)
Title: Digital debouncing and storage apparatus for use in a telephone switching system
IPC: H04J3/10
Filed: 1981-06-04
Abstract: A digital debouncing and storage apparatus operates on the receiving end of a digital carrier span line used in a telephony system to couple a multiplex signal to a receiving site to be used by the switching network control. Incoming signaling bits of the multiplex signal are stored in a random access memory at a particular storage location reserved for each channel contained in a group. There is also stored at the location previous timing information concerning each sampling bit. The circuit operates to time any change in the value of a status bit to insure that it lasts long enough to indicate a valid change of state. An up/down counter serves to time each status bit during predetermined signaling frames based on a count inserted into the counter indicative of the timing information as stored in memory. Thus each channel associated with the multiplex signal has stored in memory a unique status bit as well as timing information pertinent to that bit. The circuit operates over a predetermined number of frames whereby if the status of the bit has changed between one binary value to another, the circuit will recognize such a change only after a given number of signaling frames have elapsed. In this manner, contact bounce or channel interference which may effect the signaling bit is eliminated from interferring with system operation.

Abstract: A vacuumizing and sealing operation on a package comprises initially reducing the external pressure on the package, before sealing of the package, to a value at which the flexible film covering of the package is capable of ballooning, and ensuring heating of the flexible film of the package, preferably while an intermediate pressure is maintained (at which intermediate pressure ballooning could just be sustained without excessive evacuation to reduce the thermal capacity of the circulating air). Finally the pressure inside and outside is reduced still further before re-pressurizing.
Patent ES-8205928-A1 (ES)
Title: A torque-adjusting device for use in a roller blind.
IPC: E06B9/60
Filed: 1981-08-28
Abstract: A torque-adjusting device for twisting and untwisting a spring-motor built in a roller assembly is equipped with an easily operatable handle ring. The device includes a brake drum secured to a mounting bracket, a coil spring fitted on the brake drum, an intermediate disk disposed between the coil spring and the handle ring. The intermediate disk is integrally coupled with a stator to which one end of the spring-motor is fixed. The handle ring has an inner tongue inserted between the opposite projecting ends of the coil spring in a slit in the periphery of the disk with the result that the coil spring permits a rotational transmission from the handle ring to the stator but suppresses the counter transmission.
