Abstract: A system for controlling the amount of substituting laser gas in a discharge-excited gas laser device. A laser gas in a discharge tube (51) is substituted by an exhaust pump (7) maintaining a predetermined substitution quantity for a predetermined period of time immediately after the excitation. In the subsequent period of operation, the laser gas is ,substituted at a rate smaller than the predetermined rate of substitution. The small rate of substitution may be smaller than one-tenth the predetermined rate of substitution required for a predetermined period of time immediately after the excitation, and the laser gas is consumed in small amounts.

Abstract: The present invention relates to a process and apparatus for injection molding thin-walled plastic articles. In a first embodiment, the apparatus comprises a mold cavity (14) and a mold core (18) defining a cavity space (19) in the shape of the article and at least two injection gates (32) adjacent a portion of the cavity space defining the lip portion (30) through which molded plastic is injected into the cavity space (19). This direct lip gating approach does not sacrifice core/cavity alignment and conventional mold motions along the machine axis and forms plastic articles having substantially no gate vestiges on the lip sealing surface or on the outer perimeter of the lip. In a second embodiment, the apparatus includes a mold cavity (14) and a mold core (18) defining a cavity space (19) in the shape of the article. The cavity space has a circumferentially extending region (126) having a thickness greater than the thickness of a sidewall defining portion (122). This circumferentially extending region (126) is preferably located at the approximate mid-point of the sidewall defining portion (122). At least two gates (32) directly and simultaneously introduce plastic material initially into the circumferentially extending portion (126) in a manner so   as to minimize the creation of side loads and core shift. After the circumferentially extending region (126) is filled, the plastic material fills the entire cavity space. The plastic material is thereafter cooled to form the desired article.

Abstract: A pneumatic tire bead is formed into a spiral coil consisting of a plurality of convolutions or turns of wire. The wire may be round, square, oval or hexagonal in cross section. A crisp or offset bend is made in each of the convolutions a distance of one or a fraction of the wire width in each full 360 degree wire turn such that the ends of the bead wire permit the bead side walls to remain in flat parallel planes. This offset relationship reduces nonuniformity in the tire heretofore produced by spirally wound wire beads. The bead wire can be wound in a vertical plane or in a radial spiral clock-like spring fashion. In another embodiment a pair of mirror image offset coils are joined together to form a composite bead preferably for use in heavy duty applications. In still another embodiment a single flat hoop may be placed between a pair of mirror image offset coils to increase resistance to circumferential distortion.

Abstract: Each side of the seat squab (C) is supported by the upper ends of two arms (1, 2) whose lower ends are hinged to a rigid support member (3). The upper ends (1a, 2a) of the arms are interconnected by the rod (8) of a Porter-type locking device (9) whose body (10) is mounted on the support member (3) so that it is substantially fixed against movement in a forward-rearward direction but can move a certain distance vertically. When the Porter device (9) is disengaged, the position of the squab (C) can be varied selectively by the pivoting of the arms (1, 2). The position of adjustment thus reached may then be retained firmly by the return of the Porter device (9) to its engaged condition.

Abstract: A refrigerant compressor for using HFC 134a as a refrigerant and a refrigerator oil such as polyether type oil, polyester type oil, or similar type compatible therewith is disclosed. The refrigerant compressor includes a component of iron type substrate having a compound layer mainly made of iron sulphide on sliding portions such as sliding parts and the shaft in the compression mechanism. In a rotary type compressor, the sliding blade can have such a compound layer at its sliding surface. The hardness of the compound layer mainly made of iron sulphide can be considerable, substantially reducing metal contact and preventing adhesive abrasion; the primary cause of abrasion of sliding portions. Since such a compound layer essentially consisting of iron sulphide is stable under moist conditions, even if used in conjunction with polyether type oil, polyester type oil, or similar types of oil and HFC 134a, corrosion and abrasion through dissolution of the compound layer can also be largely prevented.

Abstract: A condom (2) is packed in an envelope (1) in rolled-up state. When it is to be used the envelope (1) is broken into two parts (3 and 4), after which the condom is rolled on with the aid of the fingers. This is sometimes troublesome. Two tapes (5 and 6) are located diametrically opposite each other and attached to the open edge (11) of the condom (2). The other ends (7 and 8) of the tapes are attached to the envelope (1) so that when the envelope (1) is opened they will be attached one in each part (3 and 4, respectively) of the envelope. When the condom is to be used, the user grips the two ends (7 and 8) with his fingers and pulls, thus effectively applying the condom (2).

Abstract: Un échantillon de liquide amniotique contenant des cellules peut être extrait de la cavité amniotique par une pénétration de la paroi de la cavité amniotique au moyen d'un aiguille creuse (15) par laquelle une quantité du liquide amniotique peut être extraite. En dehors de la cavité amniotique les cellules ou une partie de celles-ci est séparée du liquide amniotique qui est rendu de suite à la cavité amniotique. Ceci signifie qu'il est possible d'extraire une quantité relativement importante de cellules sans réduire de façon considérable le volume de liquide amniotique qui se trouve dans la cavité amniotique. Ainsi, il est possible d'extraire un échantillon à un stade précoce de la grossesse. L'échantillon peut, par exemple, être extrait au moyen d'un dispositif de prélèvement qui comporte une soupape unidirectionnelle (16, 17) qui contient un filtre cellulaire. (17). Le dispositif de prélèvement d'échantillon peut en outre comporter une seringue ayant un cylindre (10) et un piston (11), en mouvement dans celle-ci.
