Abstract: A high resolution light pen is disclosed for use with graphic displays. More particularly, a light pen is disclosed having a collimation tube slidably mounted within a housing. The collimation tube includes an axially extending channel having a non-reflective surface. A photodetector is fixably mounted within the housing aligned with the channel. A lens is mounted adjacent the front end of the channel and has a focal length equal to the spacing between the lens and an aligned pixel of the video screen. By this arrangement, all light rays emanating from an aligned pixel and passing through the lens are refracted axially along the channel and directed to the photodetector thereby maximizing the input thereto. The subject invention further includes a new and improved discrimination circuit for determining valid input signals from the light pen and producing an interrupt signal at a time substantially independent of the amplitude and slope of the input signals. In accordance with the subject invention, each input signal is compared with an upper threshold level to determine if a valid signal has been detected. In addition, each input pulse is compared to a lower threshold level for timing purposes. The result of the comparison with the lower threshold level is delayed and supplied to a gate means with the output of the first comparison. The gate functions to produce an output signal when the results of both comparisons received are simultaneously positive thereby indicating the validity of the input pulse at a time independent   of the amplitude of the pulse whereby the effects of jitter are reduced.

Abstract: In a communication system, integrated switching of voice and data is provided between terminals or lines (800) which are connected through switch adapters (301...332) to a switching matrix (50). In a first adapter, voice samples bound for the same destination or second adapter are grouped into a frame. Connections are then established between the two adapters and the frame is transmitted therethrough. This is repeated cyclically for all pairs of adapters between which transfer of voice is required. Duplex transmission can also be accomplished by transmitting two frames simulta­neously in opposite directions through a dual connection in the switching matrix. Asynchronous data (i.e. data not requiring synchronous transmission) is switched by storing these data in respective separate memories (26; P₀...P m ) of each source adapter, wherein each separate memory corresponds to a particular destination adapter.

Abstract: In order to gain access to various parts arranged in the fuselage of an aircraft, the aircraft fuselage normally has a plurality of openings which are sealed by a cover. The gaps between the opening edges and the covers are sealed with a sealing mass. In order to simplify the filling of the gaps and openings between the opening edges and covers, and to reduce its cost, and at the same time to provide the possibility of being able to remove the cover a plurality of times, without the seal having to be renewed every time, the invention provides a sealing strip which consists of two components, in each case of PTFE (polytetrafluoroethylene), namely, firstly a PTFE sealing cord of circular cross-section, and secondly a PTFE flat sealing strip which is folded around the sealing cord such that the sealing cord is surrounded by the central region of the flat strip, while the two edge regions of the flat strip rest on one another. These edge regions are welded to one another so that the sealing cord is held firmly. The sealing strip is applied to the edge of the opening of an aircraft fuselage opening, it being easy to make the perforating holes for holding the cover attachment elements. <IMAGE>

Abstract: Polyalkoxysilyl-terminated polydiorganosiloxanes which are relatively stable in viscosity over prolonged storage periods are prepared by endcapping a silanol-ter­minated polydiorganosiloxane in the presence of a catalytic amount of an acidic amine salt which subsequently decomposes to substantially inert products, preferably an amine salt of formic acid, and in the absence of silicon-nitrogen com­pounds and enoxysilanes normally used as catalyst quenchers and scavengers. The products are useful for the preparation of scavenger-free room temperature vulcanizable composi­tions, particularly when combined with certain N-alkoxy­silylalkyl-substituted compounds as adhesion promoters.

Abstract: A position pin (20) is pushed down by an effort applied on a control button (27) to disengage the position pin (20) from a position plate (18) when a selector lever is to be moved from a parking position to other gear positions. A bushing (28) is mounted on a post (14) of the selector lever for rotation but against axial movement. The bushing has at the upper end a pair of diameterically opposed notches (29) with which the position pin is engaged when pushed down to effect the above disengagement. When an ignition key is at the "ON" position and the selector lever is at the parking position, the bushing is rotated into a position where the notches are misaligned with the position pin unless a brake pedal is fully depressed, i.e., an effor applied on the control button for pushing the position pin downward is received by the upper end of the bushing whereby downward movement of the position pin for disengagement thereof from the position plate is prevented by the bushing and therefore it is impossible to move the selector lever from the parking position to other gear positions. In accordance with the present invention, there are further provided various safety means for preventing the positon pin from being errorneously aligned with the notches.
