摘要:
A yarn entangling device having a housing with an air pressure cushion in it for urging a piston normally outwardly of the housing. The piston has an air passage through it. Shifting the piston outwardly blocks the air passage. A blast nozzle is secured to the piston for being supplied with air through the piston. A baffle plate opposed to the blast nozzle defines a yarn channel. A holder supports the baffle plate for movement away from and into contact with the blast nozzle. With the holder moving the baffle plate toward the blast nozzle, the piston is shifted to open the air passage to the piston, and with the yarn channel opened with the baffle plate away from the blast nozzle, the piston is moved out of the housing by the air pressure cushion cutting off the air flow to the blast nozzle. A closing flap acts through a detent to secure the holder and baffle plate to close the yarn channel.

A template to form the characters to be written is placed between the light source and the record carrier. The template is formed as a light-switching mask the switching elements of which can be controlled by a character generator. The switching elements may be arranged separately beside each other or in matrix form in accordance with the fact whether the characters are to be written per line or per page. Printing in color is also possible. The optical printer combines the functions of a printer, a picture memory and a display.
摘要:
A sheet material finished on at least one side with a coherent surface layer is formed by electrostatically spraying a solution or dispersion of plastics producing fibers from 0.1 to 30 microns in diameter. Then the mat is consolidated with heat and pressure, whereby the fibers form a tight bond with the surface of the support material which is thus finished.

A portable grill device of the type including a first bowl and a second bowl hingedly connected together. The bowls are movable between a closure position where the bowls overlie one another, a generally right angular use position where the second bowl is disposed substantially normal to the first bowl, and a generally horizontal use position where the first bowl and second bowl are fully opened. Novel leg bail structure is provided that offers three-legged support to both bowls when the bowls are in the horizontal use position, and that offers a support base substantially wider than the width of the first bowl when the second bowl is in the generally right angular use position relative to the first bowl. Further, the portable grill device includes novel latch structure which retains the two bowls in the generally right angular position, that latch structure cooperating with spit holder arms for restraining those spit holder arms in an elevated position over the first bowl.

To provide for extended true running of the distributor shaft and prevent wear on relatively movable mechanical components within the distributor, such as a shaft and bearings, a centrifugal spark advance/retard mechanism, or the like, the relatively movable parts are included in the lubricating circuit of the engine, for example by being connected to the pressure lubrication system of the engine or located to be exposed to oil mist in the engine compartment and arising upon operation of the engine, so that the relatively movable parts are constantly lubricated by the engine lubricating system.

The invention concerns an organically electronic circuit (1, 2, 3), having a main substrate (80, 80a, 80b) and an organic electronic assembly (10, 11, 12) in the form of a multilayer film body with electrically conducting and semiconducting functional layers (101, 103, 105). In a first region (90) of the circuit (1, 2, 3) one of the electrically conducting functional layers (101, 105) of the electronic assembly (10, 11, 12), is shaped in the form of an electrode layer. Electrodes for organic field effect transistors or diodes are formed in that electrically conducting functional layer which is in the form of a first capacitor plate (201). In a second region (91) of the circuit (1, 2, 3) one of the electrically conducting functional layers (101, 105) of the organic electronic assembly (10, 11, 12), is in the form of an electrode layer. Electrodes for organic field effect transistors or diodes are shaped in that electrically conducting functional layer which is shaped in the form of a second capacitor plate (211). The main substrate (80, 80a, 80b) has an electrically conductive layer shaped in the form of a third capacitor plate (50). The third capacitor plate (50), and the electronic assembly (10, 11, 12) and the main substrate (80, 80a, 80b) are so laminated together that the third capacitor plate (50) at least partially overlaps the first capacitor plate (201) and the second capacitor plate (211) respectively, forming a capacitor.
摘要:
The processing of gas mixtures, in particular, of respiration gases for ventilated patients. The processing according to the invention relates, in particular, to the use of selective gas separation membranes for the retention of noble gases in the exhaled air of ventilated patients. The gas separation membrane is an active separator which is integrated in a ventilator. The separation membrane separates the noble gases from the remainder of the residual of the exhaled air by selectively retaining the noble gases. Thus, it is possible to provide a ventilator which enables the application of noble gases, in particular xenon, as an anesthetic preferably with low loss and as simple as possible.

A milling and drilling machine comprising a rigid machine tool frame comprising an upper cross girth, a machining unit movable on the front side of the cross girth along at least two coordinate axes by means of a motor and including a rotationally driven work spindle including exchangeable tools, and a workpiece table which is disposed in front of the machine tool frame and horizontally movable along at least one coordinate axis by means of a motor and comprises a tabletop for clamping at least one workpiece. The machine tool frame comprises two rigid side walls rigidly connected to each other by the upper crossbar and a front end.

A hydraulic vibration damper has a receiving pipe, a piston rod which projects into the receiving pipe at one end and which can be moved in an oscillating way in the receiving pipe, on the end, facing the receiving pipe, of which a working piston is disposed. The working piston comprises through-flow channels for the damping fluid which channels are effective in the pulling direction and pushing direction, and which working piston divides the inner chamber of the receiving pipe into a pulling chamber on the side of the piston rod and a pressure chamber remote from the piston rod, wherein at least a first through-flow channel can be covered to form a damping valve with a first resilient or spring-loaded valve washer which cooperates with a first valve seat. A pressure relief blow-off valve which comprises a blow-off function and opens when a predeterminable pressure level is achieved, has a first throttling site which produces progressively flowing damping force when there is increasing piston speed and whose throttling cross-section is variable depending on the piston speed of the vibration damper. In order to achieve a structurally simple construction and a low axial construction height of the valve, the pressure relief valve which has the blow-off function comprises a first annular washer allocated to the first valve washer, the first annular washer having a surface facing the first valve washer, the surface forming the variable first throttling site with the first valve washer.
