Abstract: A fitting of weldable thermoplastic material for connecting pipe elements or other fittings. The connection is obtained by welding by means of at least one heating element arranged at the surfaces of the members to be welded together. At least one weld indicator defined by a hollow space in the fitting is provided. The hollow space defines a first opening at the inner surface of the fitting and a second opening at the outer surface of the fitting. The first opening is covered by the heating element and the second opening defines a portion of reduced width, the portion of reduced width defining a retaining or cooling surface facing the interior of the hollow space. The second opening serves as an outlet opening for the melt. During welding, melt is conducted into the hollow space by the generated welding pressure. The melt solidifies when it reaches the retaining and cooling surface and only a small portion of the melt is conducted through the outlet opening for indicating a problem-free welding connection.

Abstract: A tool change apparatus for a machining center and the like comprises a spindle head (2) slidably mounted on a column (1), and a spindle (7) rotatably mounted in the spindle head (2). The spindle has at the lower end thereof a tapered tool reception bore (15) in which a tool (16) is releasably held. When a draw bar (17) is shifted upwards, resilient clamper arms (24) are forced to enter a reduced bore (14a) to be contracted thereby so that a head (16a) of the tool is clamped. When the draw bar is shifted downwards, engageable end portions (24a) are moved into an enlarged recess-like portion (14d) whereby the clamper arms (24) are allowed to expand outwards to release the head (16a) of the tool. Even when the head is released, a stop pin (33) urged by a spring (34) continues to engage the head of the tool whereby the tool is still held by the spindle. 
     Tools are held by a series of magazine pots (36). Each pot is indexed to a tool change station (B). A tool change shaft (60) has two oppositely extending pairs of tool change (68) which function to transfer tools between an indexed tool pot and the spindle.

Abstract: A pacemaker having a programmable configuration includes a plurality of solid state switches that are controlled by pro­grammed data stored in memory (32). During a pacing mode of opera­tion, a first reference electrode is switchably connected to the most positive battery potential, V DD . During a sensing mode of operation, the first reference electrode is switchably connected to -0.5 volts. The return electrode of the pacemaker, can selectively be either the pacemaker case (18) or a ring electrode (20). During a fast discharge time period, which occurs immediately subsequent to the delivery of a pacing pulse, the return electrode is disconnected from V DD  and connected to the proximal side (22) of a coupling capacitor through which the pacing pulse has passed. Also during this fast discharge time period, the most negative battery potential, V SS , is switchably connected to the proximal side of this coupling capacitor. When sensing, a first input of a sensing amplifier is switchably connected to either a tip electrode (16) or a ring electrode (20). A second input of the sensing amplifier (26) is switchably connected to a selected return electrode, which can be either the ring electrode (20) or the pacemaker case (18). Sensing can therefore occur between tip electrode (16) and ring electrode (20), tip electrode (16) and case (18), or ring electrode (20) and case (18).

Abstract: The color filters required for a thin film transistor liquid crystal display device are provided by using polychromatic glass for either the front (38) or rear (54) glass panel of the device. Through a series of masking, ultraviolet exposure and heat treating steps, red, green, and blue color areas can be generated in the polychromatic glass. Each of the different colored areas is, of course, to be aligned with one of the individually-addressable pel electrodes (42A, 42B, 42C) in the device. In a first embodiment, the polychromatic glass forms the rear glass panel (54) of the device and serves as a substrate for the thin film transistors (44) used to individually address pel electrodes (42). In an alternate embodiment, the front glass panel (38) is treated to form the color filter regions.

Abstract: Afin de stocker du liquide dans un sac constitué par une feuille sans risque de fuite du liquide, ledit sac est pourvu d'une valve ménagée dans le canal d'entrée (5). La valve se compose de deux clapets (8) formés par la feuille par pliage et soudés l'un à l'autre au niveau de leurs bords par une soudure (2) en vue de la formation du canal (5) s'étendant de l'extérieur à l'intérieur du sac. La soudure (2) présente en son centre une autre soudure ayant la forme d'une extension (3) formant un étranglement dans la section transversale du canal (5). Lorsque le liquide est versé dans le sac, il s'écoule également dans l'espace vide situé entre la feuille extérieure (1) et le clapet (8). L'eau va alors agrandir ces espaces vides fermés (7) et par conséquent comprimer les clapets (8) l'un contre l'autre. Ainsi, le liquide ne pourra pas sortir par les clapets et, en raison de l'étranglement se trouvant dans le canal, la pression produisant la fermeture sera maximale en direction des étranglements (3).

Der zeitliche Abstand von Meßimpulsen eines Drehzahlsensors wird ausgemessen und daraus der Meßwert gebildet, wobei die Messung solange durchgeführt wird, bis entweder ein Meßwertabruf erfolgt, eine maximale Zahl von Meßimpulsen registriert oder eine maximale Meßdauer überschritten wird. Wenn kein oder nur ein Meßimpuls registriert wurde, wird bei der Bildung des Meßwertes unterschieden, ob eine Meßdauer, entsprechend einer Mindestgeschwindigkeit oder Mindestdrehzahl über- oder unterschritten ist. Bei jedem Meßbeginn und bei jedem ersten registrierten Meßimpuls wird ein Anfangszählerstand, bei jedem weiteren registrierten Meßimpuls ein Endzählerstand gespeichert, bis entweder ein Meßwertabruf erfolgt oder die maximale Meßdauer überschritten ist. Das zwischen Anfangs- und Endzählerstand liegende Zeitintervall wird der Berechnung des Meßwertes zugrundegelegt.
