Abstract: A solenoid valve, particularly for use in air nozzle weaving machines, has a valve housing with at least one valve inlet and at least one valve outlet. An electromagnetically actuated valve body is arranged in a passage area between the valve inlet and the valve outlet. In order to permit a fast and operationally reliable exchange of the parts of the solenoid valve subjected to wear, it is provided that a fastening flange, the valve body, as well as the electromagnetic drive together form a first valve subassembly which is subjected to a rapid exchange. The valve housing with its connections forms a second valve subassembly which is fixedly arranged on the machine.

Abstract: A yarn cutting device for mechanical looms, having two mutually movable blades which are arranged on a mounting surface, at least one of the blades being operable by a drive. The drive is constructed as an electrically energized linear motor, whereby a compact flat construction is achieved which has few movable parts.

Abstract: A thermal cycling device for use with self-heating microscope slides is provided.

Abstract: A clamping holder for flexible lines, particularly current-carrying lines, has a line holder with at least one device for fixing a line and a device clamping the line in the device. The device and the line holder have at least one mutually aligned passage, respectively. A known type of elastic, longitudinally extendible tension device is pulled into the passages. The tension device has a neck-type cross-sectional contraction and connects the line holder with the device in a ventable manner.

Abstract: Use of a compound of the formula I ##STR1## for the manufacture of a medicament for the treatment of pain. The compounds are .delta. opioid agonists and thus useful in the treatment of pain without the requirement of co-application of a .mu. opioid agonist.

Abstract: A weft thread clamp for a weft thread presenting lever is positively actuated to selectively open or close the clamp and thereby release or hold the weft thread respectively. To achieve this, a second clamp element is movable or deflectable relative to a first clamp element of the clamp. The movable second clamp element may be directly embodied as an actuator, or may be driven by an actuating motion provided by an actuator located remotely from the clamp on the lever. In the latter case, a motion transmission arrangement such as a sheathed push-pull cable or a rod linkage operatively connects the actuator to the movable second clamp element. The actuator may be a piezoelectric, electromagnetic, hybrid pneumatic-electric, or hybrid hydraulic-electric device, or an electric motor. The loom control unit is connected to the actuator for providing control signals thereto.

Abstract: An air nozzle weaving loom has a prenozzle alignment arrangement for the weft yarn picking. Several prenozzles (8a) having respective blow pipe (8b) are accommodated in a prenozzle block 9 according to an order system (geometric configuration) corresponding to the order system (geometric configuration) of main nozzles (5a) in the main nozzle block (6).

Abstract: A method and apparatus employs Hall probes for contactless, longitudinal and transversal homogeneity examination of a critical current density j.sub.c in a superconductor tape that is cooled to below a transition temperature T.sub.c. The cooled superconductor tape is pulled through an external, locally limited magnetic field that has a constant gradient and a fixed magnetic field axis. The magnetic field generated by a screening current induced in a region of the superconductor tape penetrated by the external magnetic field is scanned using a first Hall probe at a distance of a few tenths of millimeters to the superconductor tape. The external magnetic field outside of a field range of the induced persistent currents is measured with a second Hall probe. A compensated difference between the first and second Hall probe signals is used as a qualitative measure for a critical current density j.sub.

Abstract: A controlled weft thread presenting and clamping arrangement minimizes weft thread waste and ensures proper tensioning of the weft thread during its presentation to the insertion gripper, in a gripper loom for weaving with plural different weft threads. The arrangement includes a control shaft (13) that has a drive key (14) protruding therefrom in a reference plane (7), and that is rotatably supported on a support bracket (10, 11, 12), which may be mounted on the loom. Weft thread presenting levers (15) each carrying a respective clamp (16) are movably arranged on the shaft (13), which passes through a hole in each of the presenting levers (15). A translational drive (22) acts on a presenting lever support (17) to translationally move all of the presenting levers (15) in unison together axially along the shaft (13) until a selected lever (15) is positioned in the reference plane (7), with the lever's drive groove 15B engaged on the drive key (14) of the shaft (13).

Abstract: Compounds of the formula I ##STR1## as well as methods for their preparation, their pharmaceutical preparations and their use in therapy, especially as analgesics and as immunosuppressive agents.

Abstract: A wide selvage is formed along a fabric edge in a weaving loom by at least two selvage forming heads arranged in a row with an outer selvage forming head (9) and an inner selvage forming head (8) positioned between the outer selvage forming head (9) and an edge of a fabric. The outer selvage forming head (9) seizes a weft end and transmits it to the inner selvage forming head (8) which inserts it into the shed for beat-up. Both forming heads work pneumatically and in tandem with each other. A set of two selvage forming heads (8, 9) is arranged at each fabric edge.

Abstract: A combined weft thread clamp and cutter apparatus for an air jet loom includes a cutter (3) for cutting a weft thread (1) and a clamp (4) for clamping the weft thread (1). The cutter includes a fixed cutter element (10) and a movable cutter element (9) that is movable relative to the fixed cutter element. The clamp includes a first clamp element (14) and a second clamp element (13). The clamp (13, 14) and the cutter (9, 10) are arranged next to each other, and a spacing distance (8) between the clamp (13, 14) and the cutter (9, 10) is adjustable. The clamping surface of at least one of the clamp elements (13, 14) can be an elastically yielding surface.

Abstract: The invention concerns compounds of the formula 1 ##STR1## and pharmaceutical compositions containing the compounds as active ingredients. The peptides of the invention are .delta. opioid receptor antagonists and are useful as analgesics and immunosuppressants.

Abstract: An impermeable cooled closing plug adapted for closing the end of a semiconductor manufacture processing tube is made of a material selected from the group consisting of quartz, silicon and silicon carbide, which materials have low heat conductivity and high chemical stability. The cooling effects of a cooling liquid supplied to the entrance flange of a processing tube are isolated from the tube closing plug by virtue of the low heat conductivity, thus preventing unwanted condensation effects at the entrance of the tube.
