Abstract: 1. A process for the preparation of a resilient foam based on a melamine/formaldehyde condensate by foaming an aqueous solution or dispersion, which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent, with or without conventional additives, and then curing the foam, wherein a) the concentration of the precondensate in the mixture of precondensate and water (without additives) is selected to be above the salient point of the 1st derivative of the curve which is obtained when, keeping all other conditions constant, the amount of water in the mixture of precondensate and water is varied and the viscosity of the mixture (measured at the boiling point of the blowing agent under the conditions prevailing at the start of foaming) is plotted against the concentration of the precondensate, which concentration must however not be higher than the value which in the curve described corresponds to a viscosity of 5,000 dPas, b) during the foaming process, up to the time at which the foam has reached 80% of the maximum attainable rise height, the viscosity of the aqueous solution or dispersion must not fall below the value which, in the curve described under a, corresponds to the minimum concentration defined there, but must not exceed 6,000 dPas, and c) after reaching the time defined under b, the viscosity exceeds a value of 10,000 dPas, due to curing of the precondensate, within 8 min, the viscosities referred to in b and c being measured, in each case, on a parallel system which is free from blowing agent.

Abstract: An interior core protector (20) for protecting the interior (12) of a coil of material (10), e.g., coiled sheet steel, from damage is disclosed. The core protector (20) includes a pair of overlapping formed angular paperboard members (22, 24) each having a series of spaced die cuts (26) in one leg (22b, 24b) thereof permitting the angular members to be bent to conform to the inner diameter of the coil (10). The cuts (26) in one leg (22b) are offset from the cuts in the other leg (24b) such that when the protector (20) is bent for placement in the interior core (12) of the coil (10) and the width of the cuts (26) increases, a paperboard segment of one member (24b) nevertheless overlies the cut (26) in the other (22b) to provide protection for the material about the full circumference of the interior core (12).

Abstract: A method and apparatus for removing oil from water. The invention includes a separation vessel for separating the oil by gravity from the water. The generally oil-free water from the separation vessel is pumped under pressure through an ultrafine molecular filter. The concentrate liquid from the ultrafine molecularfilter is directed into a concentrator vessel which separates out the oil which remains in the concentrate liquid. The separated oil is directed back into the separation vessel and the remaining liquid is directed back through the ultrafine molecular fitter. Ejection water is periodically directed into the separation vessel to discharge oil accumulated in the separation vessel.

Abstract: The invention relates to a method and apparatus for separating knots. In particular the method and the apparatus are meant to be used in separating knots from fibre suspensions of the wood processing industry. The knotter according to the invention uses a profiled screen cylinder (5) with which it has been found from performed tests to be most preferable to feed the pulp from the connections (2) in the direction of rotation of the screen cylinder and also to discharge the reject from the connections (4) and the accept from the connections (3) of the cylinder (5) in the direction of rotation. As a result, there is not only less wear of the screen surface, but also a significantly smaller consumption of power per pulp ton than in the apparatuses in accordance with the prior art.

Abstract: A golf bag has legs attached to its side which are movable between a retracted position against the side of the bag and an extended position where they act in cooperation with the base of the bag to support the bag at an acute angle with respect to the vertical so that golf clubs carried in the bag are readily accessible. The legs are movable to their extended position by a rod which extends from the legs to the bottom of the bag.  A portion of the base of the bag adjacent to the actuation rod is relieved thereby permitting the bag to be placed vertically on its base without interference from the rod while still allowing the rod to be moved by placing it on the ground and pushing the bag downwardly.

Abstract: Selon la présente invention, sur un plan cristallographique (100) d'un substrat semiconducteur à conductivité d'un premier type, on fait croître successivement une première couche de métallisation à conductivité du premier type, une couche active, une seconde couche de métallisation à conductivité d'un second type et une couche d'encapsulation beaucoup plus réceptive à la gravure latérale que la seconde couche de métallisation. Puis on forme sur le substrat un masque en forme de ruban orienté dans la direction <011> par rapport à chacune des couches du substrat multi-couches. Cette gravure est réalisée selon une orientation du cristal pour former un mésa en triangle inversé. Toutefois, comme la couche d'encapsulation est en matériau sensible à la gravure latérale, on forme un mésa arrondi. Par la suite, lorsqu'une couche d'enfouissement est déposée par épitaxie en phase gazeuse sur la partie gravée, on peut donner à cette couche une surface plane selon les orientations du cristal.
