Abstract: Fibres are produced by centrifugal spinning a solution of a thermosetting aldehyde resin, e.g. an aqueous UF resin solution, and drying the fibres by contact with a stream of hot, dry, air flowing downwardly from above the spinning cup. 
     To avoid premature drying of the resin solution and fibres, a stream of cold, humid, air is fed to the spinning cup (5), from whence it is thrown, by rotation of the cup, as an outwardly directed stream (11) having the fibres (10) entrained therein. This outwardly directed stream of cold, humid, air is deflected downwards, e.g. by the hot, airstream (16) or by a subsidiary cold air stream, to avoid the formation of a vortex into which the fibres might become entangled.

Abstract: An inner shield (26) made of a magnetic material for shielding the earth magnetism is provided in a color picture tube for preventing the mislanding of the electron beams on phosphor stripes that might otherwise result from the bending ofthe electron beams caused by the earth magnetism. The inner shield (26) is formed by securing a pair of short side sections (26-3, 26-4) and a pair of long side sections (26-1, 26-2) to a mask frame (20) such as to define a substantially rectangular space through which the electron beams pass. Gaps offering increased magnetic reluctance are provided between the short side sections on one hand and the long side sections on the other hand; whereby the components of the horizontal earth magnetic field vector are adjusted to cancel electromagnetic forces acting upon the electron beams.

Abstract: The present invention is directed to a process for the preparation of certain N-substituted -2-haloacetanilides via the reaction of a secondary 2-haloacetanilide with a haloalkyl ether, particularly, halomethyl ethers, which comprises forming the ether in situ by the in-solvent reaction of an alcohol, formaldehyde or other aldehyde and an acid halide to produce high purity haloalkyl ethers, while decreasing the concentration of undesirable bis by products, as for example bis(chloromethyl) ether. The ether formed in situ thereafter reacts with the secondary 2-haloacetanilide in the presence of a phase transfer catalyst and base to form the N-substituted-2-haloacetanilide.

Abstract: A thermally-activatable image-forming composition contains a cobalt (III) complex having releasable ligands, an amplifier compound which reacts with cobalt (II) or released ligands to form an agent for the conversion of the complex to cobalt (II) and released ligands, a material which generates an image by dye formation or dye destruction in response to imagewise conversion of the complex, and a destabilizer which facilitates conversion of the complex, and hence the image-forming reaction, by heating, is characterized by containing as the destabilizer two destabilizer compounds which are present at concentrations such that the temperature required for initiating the image-forming reaction is lower than the initiation temperature obtainable using either destabilizer compound alone. Images can be produced in coatings of the composition by imagewise thermal exposure or by incorporating a photoinhibitor in the composition and exposing the coating imagewise prior to heating overall.

Abstract: An electronic phase-sequence indicator for three-phase electric systems. It serves to individuate the cyclic sequence order of the three phases. The apparatus is composed of a single-phase indicator-detector having an ammeter circuit and a voltmeter circuit suitably connected with resistors and condensers, or else with inductances and capacitors. 
     It is provided with a ferromagnetic core upon which the electric ammeter circuit acts, obtained with a small- sized coil composed of a very thin copper wire wound according to an extremely large number of turns. Between the pole pieces of the ferromagnetic circuit the voltmeter moving element is placed, which is composed of a small frame, free to rotate, upon which the voltmeter small coil is wound, which is composed of many turns of a very thin copper wire. Upon the axle of the small frame two spiral springs are keyed which have the functions of determining the counteracting torque and of vonveying the voltmeter current to the small coil. Upon the axle of the voltmeter moving element also the pointer of the device is keyed which, in the rest position, is situated at the center of the dial of the device. 
     The indicator-detector is provided with a dial of the center-zero type, divided by a line into two sectors, each of which shows suitable indications, red and green colored, for the correct and simple use of the sequence- phase indicator. 
     In order to avoid the oscillations of the pointer, the moving element may be provided with a damping device which may be of the air or the electromagnetic type.

Abstract: Un mât de levage amélioré (10) permettant d'avoir une bonne visibilité élimine les problèmes de hauteurs de levage réduites, de résistance réduite des montants et de chargements excessifs sur les paliers de guidage.

Le montant mobile (42) est mobile en élévation sur une première distance présélectionnée à laquelle le montant mobile (52) peut entrer en contact avec le palier de guidage intermédiaire (98) et n'est pas en contact avec le palier de guidage supérieur (88) et sur une seconde distance présélectionnée à laquelle le montant mobile (42) n'est pas en contact avec le palier de guidage intermédiaire (98) et peut entrer en contact avec le palier de guidage supérieur (88). Ainsi, il a été possible d'obtenir un mât de levage ayant une visibilité améliorée, avec un levage libre et offrant une hauteur de levage maximum pour une longueur de montant donnée, une plus grande résistance des montants, et une charge séquentielle sur les rouleaux pour en améliorer la longévité.
