Abstract: A process for manufacturing coating panels in different shades and with different degrees of surface finish. 
     Such process makes it possible to produce panels the surface of which, bound to face outwardly, presents two separate areas, one of which is recessed as compared to the other. 
     Said process requires the employment of a die-counterdie (11,12) unit for the moulding of the abovementioned panel, in which the surface (21) of the die (11) defines that part of the panel which is bound to be external.

Abstract: Projecteur/trieuse de diapositives ayant une chute (16) orientee suivant un plan incline par rapport a l'horizontale, concu pour recevoir des diapositives photographiques a une extremite. La diapositive tombe par gravite dans une station de projection (20) ou elle est tenue par un linguet (22). Apres projection de la diapositive, le linguet est actionne pour liberer la diapositive qui est transportee par gravite vers une extremite inferieure de la chute ou elle tombe dans un premier receptacle (26). Le premier receptacle est monte en rotation de maniere a pouvoir etre deplace hors du chemin, permettant ainsi a la diapositive de tomber encore plus bas dans un second receptacle (34), ayant plusieurs compartiments. Le second receptacle est monte de maniere telle que chaque compartiment puisse venir se placer sous la chute.

Abstract: It is often desirable to produce a laminate that simulates another product, e.g. a wood grained surface. However, although it has been possible to use a decorative surface having a print pattern thereon and texturize the surface, it has not usually been possible or convenient to impart a texture conforming to the print pattern. 
     This invention concerns an improvement in the production of textured decorative laminates which allows for greater realism, warmth and a contrasting textural quality heretofore not attainable 
     The method of this invention for imparting highlights or shadows to a decorative laminate comprises the steps of preparing a textured decorative laminate by compression molding utilizing a pigmented release sheet to cause transfer of pigment to the laminate, and then rubbing the surface of the pigmented textured laminate to the extent necessary to remove some of the applied pigment, with more pigment being removed from the raised areas of the laminate than from the depressed areas thereof.

Abstract: A spin casting style fishing reel is provided with an anti-reverse mechanism which prevents the crank assembly from being rotated in a reverse direction wherein fishing line is payed out, when a selection switch for the mechanism is set in a first position. The selection switch can be selectively moved between the first position and a second position for activation and deactivation of the anti-reverse mechanism. A lever portion of the anti-reverse mechanism has an integral activation arm which follows the movement of the selection switch between the first and second positions, activating and deactivating the anti-reverse mechanism, and a bias receiving arm to which a spring is mounted to hold the activation arm in engagement with the selection switch.

Abstract: A lance for blowing an oxydizing gas onto a bath of molten metal, especially for blowing oxygen on a bath of molten pig iron for transforming the same into steel. The lance is provided in an end wall of its nose with at least one central aperture for blowing gas jets at great impulsion onto the bath and a plurality of auxiliary apertures for blowing gas streams of considerably smaller impulsion onto the bath. The auxiliary apertures are constituted by elongated slots through the end wall arranged spaced from each other along a circle at a distance of adjacent edges of the slots and that at least one main aperture of about 2-20 cm. This construction permits to improve the amount of secondary combustion of the reaction gas while prolonging the useful life of the nose of the lance. The lance is advantageously used in conjunction with blowing a stirring gas through the bath of molten metal through refractory gas permeable elements provided in the bottom of a crucible containing the bath.

Abstract: The textile fiber sliver is deposited in cans in the form of cycloid-type loops. During deposition, the sliver is delivered via a rotating funnel gear wheel into a rotating can. In addition, the mutual distance between the axes of rotation of the gear wheel and can is varied by laterally displacing the can. Also, the rotational speed of the can is varied during operation so that when the distance between the axes of rotation of the wheel and can is at a minimum, the can rotates at a maximum speed. Likewise, when the distance between the axes of rotation is at a maximum, the can rotates at a minimum rotational speed.

Abstract: A reaction vessel (1) having a ring-shaped flat bottom portion (3) and a conically inclined bottom portion (4) is used to detect a particle agglutination reaction. Images of particle patterns formed on the flat bottom portion (3), middle and lowermost portion of the inclined bottom portion (4) are separately detected by first (21), second (20) and third (19) light receiving elements to produce first, second and third signals. When the first signal is within a predetermined standard range, the particle agglutination reaction is judged by comparing a difference between the second and third signals with a predetermined upper and lower standard values. Contrary to this, when the first signal is beyond the predetermined range, the judgement for the agglutination reaction is not effected.

Abstract: Disclosed is a method for the purification of propylene polymers which comprises bringing a propylene polymer containing volatile components into contact with a gas consisting mainly of propylene at a temperature lower than the melting point of the polymer, whereby the volatile components are removed from the propylene polymer. 
     A process gas obtained by evaporating the reaction medium contained in a slurry resulting from bulk polymerization using propylene itself as the reaction medium or a process gas separated and recovered from a polymerization mixture resulting from vapor phase polymerization is suitable for use in the practice of the present invention, because its dew point is low enough for drying purposes and it can be recycled in large amounts. 
     The method of the present invention permits the volatile components contained in the polymer to be removed to substantially the same extent as is attainable by the conventional drying method using a large amount of nitrogen gas. Thus, the present method has very great economic advantages over the conventional one.
