Patent EP-0245087-B1 (EP)
IPC: G02B6/38
Filed: 1987-05-06
Granted: 1992-07-29
Abstract: An apparatus for terminating an optical fiber includes a resiliently deformable spherical member disposed in contact with a front end of a bore of an optical fiber contact body. Subsequent to softening an adhesive disposed within the contact body bore, an optical fiber is inserted through the bore and the adhesive until the fiber contacts the blocking member and deforms it. The resiliency of the blocking member causes adhesive to be wiped off the front face of the fiber being terminated and into an annulus formed between an outer cylindrical surface of the fiber and an inner cylindrical surface of the bore, and causes the fiber front end to be recessed a predetermined amount from a front end of the contact body.

Abstract: Apparatus for resistance welding an elongate seam in a tubular article, comprises a first electrode wheel 1 outside the article, a second electrode 2 inside the article and a continuous electrode wire arranged to pass over the electrodes to provide surfaces of contact between the electrodes and seam material. The second electrode has a stationary block 6 having a guide surface of like curvature to that of the outer electrode wheel 1 so that the contact arcs of wire passing over the guide surface with the seam material is substantially equal to the contact area of wire passing over the external wheel 1. The use of this stationary inner electrode improves the weld geometry and permits welding of can bodies of relatively smaller diameter without use of mercury contact bearings.

Abstract: Device for tensioning a traction element (1) in a printer, especially in a matrix printer, for a backwards and forwards movement of a component (5) presupposes a first, driven deflection roller (11) mounted fixedly on the frame so as to be able to rotate and a second deflection roller (12). In addition, a wedge-shaped area (15) is present which, with increasing inclination (16), is displaceable parallel to a frame surface (17) running vertically to the traction direction (18) and is subject to the force of a tension spring (22) so that the adjustable, second deflection roller (12) serves as a means of increasing the traction force in the traction element (1). In order to create the most rigid system possible which also takes account of the production elongation of a traction element (1) - traction element - it is proposed that the second deflection roller (12) with its roller bearings (24) is mounted, so as to be able to rotate, in a lever (13) constructed as a covering housing (23), that in the housing (23) an adjustable cam (25) is mounted adjacent to the wedge-shaped area (15) so as to be able to rotate and that the cam position can be fixed. <IMAGE>

Granted: 1991-03-20
Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.

Abstract: In rollers, especially those used for continuous casting of strips (40) of aluminum and other metals, the coolant flows between the roller shell (7) and the roller core (8) through axial cooling channels (26). The counterflow principle is here applied, so that the coolant alternatively flows in the cooling channels (26) from one front side (41, 41a) to the other and is discharged there. A bore divided into an axial channel (15) and into a tubular channel (16) for supplying and discharging the coolant extends from one front side of the roller (1) to the other front side. Alternating supply and discharge ducts for the cooling channels (26) that extend over the whole length of the roller core (8) are arranged in such a manner near both roller front sides that the coolant flows according to the counterflow principle. The cooling channels (26) are formed of longitudinal grooves in the core (8) and shell (7) of the roller.

Abstract: An apparatus for the biostimulation and treatment of organic tissue is described, which apparatus is distinguished by its minimal size with a housing volume of approximately 50 cm<3> and a short focal distance of the focused laser radiation (8). Provided in the beam path of the apparatus is at least one convex lens (2) which in terms of function is used for adjustable focusing between the laser radiation outlet opening and the interior of the housing. The laser is a cw diode laser (1) in the visible red to near infrared wave range (600-1100 nm), preferably 780 nm or 670 nm, with a design-related optical output of 0.5 to 10 mW, which in this apparatus, as a result of the great divergence of the laser beam in the further course of the beam, does not represent any risk to the human eye and at the same time has a relatively high power density (8) acting on the surface to be treated. A sensor ring (7) at the beam outlet opening assumes the function of a barrier. <IMAGE>

Abstract: Dans un enregistreur comportant deux têtes en ligne (140, 142), telles qu'une tête d'enregistrement suivie par une tête de reproduction, il est nécessaire d'assurer un angle de guidage de bande adéquat (152) au niveau de l'élément transducteur (148, 149) de chaque tête. Comme la bande (150) s'étend entre les deux têtes en ligne (140, 142), elle (150) quitte le sommet (156) d'une tête (142) à un angle de guidage zéro et arrive au sommet (158) de la seconde tête (140) avec un angle de guidage zéro. L'invention prévoit des supports (162, 166) sur chaque ensemble de tête (140, 142), guidant la bande (150), et préconise de placer chaque élément transducteur (148, 149) hors du sommet (156, 158) de son ensemble de tête, afin de maintenir des angles de guidage adéquats au niveau de l'élément transducteur (148, 149) de chaque tête en ligne (140, 142). Les supports (162, 166) comportent des fentes éliminant l'air piégé afin d'empêcher que la bande ne s'écarte, ce qui entraînerait une perte de contact avec les éléments transducteurs (148, 149). Les contours des supports (162, 166) et les supports (170, 171) sur lesquels les éléments transducteurs (148, 149) de chaque ensemble de tête (140, 142) sont placés, forment des profiles de surfaces constants afin que les caractéristiques d'usure des ensembles de tête (140, 142) soient constantes.

Abstract: A video recorder with automatic still picture positioning senses during moving picture mode the levels of the waveform of the FM signal for successive fields and calculates a ratio from these levels. In still picture mode, the waveform levels are measured at respectively corresponding angular positions with respect to head switching pulses, and level ratios are likewise calculated. These actual level ratios are compared with set level ratios, as have been obtained from the moving picture level ratios in consideration of geometrical characteristics of the playback arrangement. From the deviations between level set values and level actual values, a respective tape position correction value is obtained. By constantly matching the level set values to the current ratios, it is ensured that the tape position correction values are appropriate for the current ratios. <IMAGE>
