摘要： A windshield for motor vehicles equipped with a windshield wiper system, which, for the improvement of the wiped field, includes in its lower area strip-shaped profile members whose side facing the bottom edge of the windshield form together with the windshield surface a water-collecting channel open in the downward direction. In order to prevent the rising of water from non-wiped areas in the lower part of the windshield onto wiped higher areas, provision is made according to the invention that the upper edge area of each profile member extends along the lower edge area of the associated wiper field.

A screw cap (5) is provided with internal threads (53) and a flange (52) which sealingly clamps a flange (42) of the teat. A spike (3) accommodated completely within said teat and having a pointed tip (31) on its one end and a pushbutton-like enlargement (32) on its other end, is guided within an opening (22) of a longitudinal guiding portion (2). The longitudinal guiding portion (2) extends partially into the interior of the teat (4) and has a flange (21) thereof fixed by the screw cap (5). The spike (3) has a longitudinally (axially) extending groove (33) which, in combination with the wall of opening (22) opposing this groove, defines a passage for liquid dispensed from the container (1) when the spike has penetrated the pierceable wall (13). Upon penetration of this wall, the spike remains within the interior of the teat or of the container (1), respectively.

摘要： A dental syringe employs a single thumb or finger operated control member mounted on the syringe for regulating the flow of air or water or spray. The single control moves axially and vertically with respect to the syringe. Axial movement either forward or rearward from a rest position, initiates and controls the quantity of flow of air or water. Vertical movement of the control member initiates the flow of both air and water to produce a spray.

摘要： The single circuit refrigeration plant includes a housing which provides three concentrically located contiguous compartments including a first one interposed between the pressure side of the compressor and the condenser, a second one interposed between the first and the third, the third compartment being interposed between the second compartment and the evaporator. The first compartment is axially centrally located; it is directly ringed by the third compartment and is also ringed by the second compartment. In use, as the compressed gas stream enters the first compartment the pressurized oil therein separates therefrom and the resultingly de-oiled compressed gas stream flows to and through the condenser, through the fluid collector, to and through the evaporator to the third compartment in which it separates into a further liquid component which is combined with the degassed oil in the second compartment, and the remaining gas stream is returned to the suction side of the compressor, meanwhile: the oil degassed and collected in the second compartment is cooled at least in part by indirect heat transfer by contact with the third compartment and is returned to the compressor.

摘要： There are needed galvanic baths for the deposition of silver and silver alloys which exhibit a high resistance to sulfur and contain the least possible amounts of alloyed platinum group metals and/or gold. This is attained by using a salt melt as the electrolyte which melt contains a silver salt, alkali thiocyanate and salts of at least one alloying metal. Preferably the electrolyte contains per liter of salt melt 0.1 to 40 grams of silver and 1 to 200 grams of platinum metal and/or gold.

摘要： A voltage supply for an X-ray tube provides both high and low voltages to the tube. A high voltage transformer using split primary and secondary windings is employed. The high voltage is switched on and off by selectively phasing the voltage across the transformer's secondary coils. Low voltage is coupled from one of two primary windings.

摘要： A rotary slide closure for a vessel provided with a fire-proof lining includes a closure block contacting a beveled seat of a seat block and being rotatably mounted relative to the seat block. The closure block and the seat block each have at least one flow-through opening which can be brought into register by turning of the closure block so as to form a pouring channel extending from the center of the closure block. The surface of the seat block forming the beveled seat, faces the interior of the vessel and the closure block contacts the surface forming the bevel seat from the interior of the vessel.
