Title: Dispositif pour refroidir un produit long en défilement
Inventor: BERTOLOTTI FRANCIS
IPC: C21D9/08
Filed: 1980-01-18
Abstract: Dispositif pour refroidir un produit long en défilement, comprenant un tube allongé parcouru par un liquide refroidissant et dans lequel passe également le produit à refroidir. Conformément à l'invention, le tube 1 est équipé intérieurement d'un organe de centrage 13 du produit en défilement, comportant un passage central 14 de diamètre inférieur au diamètre intérieur du tube 1. Avantageusement l'organe de centrage 13 présente des canaux longitudinaux périphériques 16 répartis autour du passage central 14 pour faciliter la circulation du liquide refroidissant. L'invention permet d'améliorer l'homogénéité du refroidissement et s'applique préférentiellement aux produits de format assez grand, tels que das barres d'acier qui, en raison de leur poids et de leur faible vitesse de déplacement, sont plus sujets que d'autres à venir en contact avec la paroi interne du tube.

Abstract: A magnetic recording method for recording a multiplex signal comprising two different frequency signals. There is used a magnetic recording medium having a magnetic layer with the thichness smaller than recorded wavelength of each of said two signals. The signal of higher frequency is recorded at a current larger by more than 2 dB than the lower limit of the recording current with which a reproduced output level is saturated, and smaller than a current with which the reproduced output level is reduced by 1 dB beyond said saturated condition. And the signal of lower frequency is recorded at a current smaller than a half as large as that of the signal of higher frequency.

Abstract: A method for the splicing of two twisted staple yarns includes the steps of untwisting portions (6a, 7a) of each yarn (6, 7), drafting these portions to form beards (35) and retwisting the beards to form the splice (40). In one aspect of the invention, the untwisting is effected by rolling the yarns between two surfaces (13) at nip point (18) to rotate the yarns. In a second aspect, each yarn is gripped between nips (18) at two locations (defining the respective yarn portion) which are spaced apart by a distance not significantly greater then the mean yarn fibre length; after untwisting, the beards (35) are formed by drawing the ends of the yarns in opposite directions and longitudinally through the adjacent nips (18), whereby both ends (35a) of each beard (35) are held between the nips (18) defining the respective yarn portion (6a, 7a). Also disclosed is apparatus forcarry- ing out the respective aspects of the method.

Abstract: A process is disclosed for the conversion of carbon monoxide in sour synthesis gas mixtures in the presence of a catalyst which is active in the presence of sulfur compounds. The catalyst comprises known sulfactive metal oxides or sulfides supported on a shaped carrier. The catalytically active oxides or sulfides are doubly promoted with an alkali metal compound and an oxide or sulfide of a multivalent metal of Period 4 including titanium, vanadium, chromium and manganese. The two promoters provide a synergistic effect on the activity of the catalyst. The catalysts are active at relatively low temperatures of less than 260°C even in the presence of sulfur compounds. The equilibrium for the conversion of steam and carbon monoxide to hydrogen and C0 2  is favored at lower temperatures.

Abstract: A brake pressure proportioning valve incorporates a failure sensitive feature whereby a secondary plunger (32) is subject to pressure at a secondary inlet port (15) and assists a primary plunger (17) to overcome the load of a biassing spring (31) when pressure at the outlet port (16) reaches a predetermined magnitude. The plungers then move to allow a metering valve ball (27) to seat and prevent pressure from a primary inlet port (14) reaching the outlet port (16) without reduction. If pressure at the secondary inlet port (15) fails, this predetermined magnitude increases. The valve is made compact by arranging the secondary plunger (32) between large and small diameter portions (18 and 21) of the primary plunger.

Abstract: A gas laser is provided in which the plasma chamber (2) can be quickly and easily replaced by relatively unskilled personnel. This feature makes it possible to use sealed plasma chambers (2) in applications where lasers are operated only intermittently and sealed plasma chambers (2) have limited operating life. With the elimination of the gas handling system, it becomes posssible to manufacture compact, and in some important cases, portable and light weight lasers with replaceable plasma chambers (2). The invention is addressed to lasers operating at low to medium power output. 
     To make chamber (2) replacement possible without need for elaborate optical realignment, one section of a mating mechanical coupler (76,78,82,84) is secured to the non-conductive envelope (4) of the demountable plasma chamber (2) and is positioned in a predetermined spatial and angular position with respect to the electrodes (12,14), optical windows (26,28) and the optical axis of the plasma chamber (2). The positioning of the mechanical coupler with respect to the electrodes (12,14), the windows (26,28) and the optical axis is identical for each of the interchangeable plasma chambers (2). A separate base (32) is provided with the other section of the demountable coupler fixed in a precise predetermined spatial and angular position with respect to a pair of mirrors (52,54) mounted on the base (32). The position of this section of the mechanical coupler (76,78,82,84) with respect to the mirrors (52,54) is identical for each of the interchangeable bases (32).

Abstract: Under particular conditions, a cationic ring-opening polymerization of an oxirane monomer selected from the group consisting of an acyclic glycidyl ether, a cyclic glycidyl ether, and a haloalkyl epoxide, in the presence of a hydroxyl-contain- mg backbone of a polymer ("HCB") and a particular catalyst, produces a polymenzation having 'living polymerization' characteristics, provided the OH groups are aliphatic OH groups and not aromatic OH groups. The result is a graft copolymer the molecular weight (mol wt) of which is directly proportional to the conversion of the monomer. The HCB, which may have from 1 to 400 pendant OH groups, and more preferably at least 7 pendant OH groups, provides grafting sites for the grafting segments. Where a grafted segment contains halogen, the segment may be aminated. If the HCB is hydrophobic, the aminated block copolymer is amphiphilic.
