Title: Circuit generating position modulated pulses - is for telecommunications exchange and has counter receiving basic clock pulses corresponding to width of time position pulse
Inventor: DIRR JOSEF ING GRAD
IPC: H04M19/02
Filed: 1977-10-31
Abstract: The circuit has an electronic counter to which fundamental clock frequency pulser are applied, corresp. to the width of a time position pulse or of a space between pulses or to a fraction of it. The width of position modulated pulses, when they should be a multiple of the fundamental timing frequency, is obtained by connecting two or more outputs of the counter to gates. When certain characteristics (e.g. zones) are allocated to certain devices, pulses are allocated to them whose width corresponds to the width of all pulses and spaces of all characteristics. After each counter runs through its range, a pulse is applied to the counters for the PPM pulse generation.

Title: End seal for multi-tube, remote-control conduit - ensures impermeable insulated division into groups and single tubes
Inventor: SCHWARTZE HANSJUERGEN DIPL PHY
IPC: F16L47/22
Filed: 1978-03-11
Abstract: A conduit consisting of groups of different tubes, with or without a cable, which may or may not be temp. modulated, has an end seal fitting over the plastic sheath, which completely excludes moisture. Since corrosion is ruled out by this, the cost of the material forming the tubes and/or cables, can be kept to the minimum. The seal includes a sleeve and caps with fingers which divide the core of the conduit firstly into groups and then into single branches. It is of a thermoplastic material such as a polyolefin or PVC, which contracts on heating. Liners are inserted in the sockets of the sleeve through which the groups pass, so as to keep their shape and ensure a tight joint when the caps are shrunk on. When the conduit is heated or cooled the separate tubes are wrapped with in insulating material before the caps are fitted.

Title: De-multiplexer with clock generator - uses clock frequency of time multiplexed signal to derive clocking for synchronisation circuit
Inventor: KUEHNE FRIEDRICH DR ING
IPC: H04J3/12
Filed: 1978-03-31
Abstract: The demultiplexer has a clock generator whose faster part derives a clock frequency for the first part of a synchronisation circuit and a clock frequency for the same synchronisation circuit, for the channel parts and for the slower part of the clock generator. Both these two clock frequencies are derived by the faster part from the time multiplexed signal's clock frequency. The first part of the synchronisation circuit - on receipt of a frame recognition pulse at its second part and at the faster part of the clock generator - releases a reset pulse.

Title: Bulls-eye window panel mfr. - by gravity sag of heated pane between bar grid meshes
Inventor: BRUENING KLAUS DIETER
IPC: C03B23/025
Filed: 1978-08-17
Abstract: Ornamental glass window panes with a regular pattern of convex areas, are produced by laying a flat pane on a frame which is subdivided by two groups of parallel bars at right angles to each other. This set is inserted into a kiln and heated so that the glass becomes plastic and forms a curve by gravity in each free space between the bars. A light barrier detects that the gas has reached the desired depth so that the heat can be cut off and the pane is allowed to cool. This produces a bull's eye type of window without the sealing difficulties of lead surrounds which can be frames just like a flat pane. The pattern can quickly be changed.

Date May 29, 1980.Steam generator, preferably for use in nuclear energy plants, which comprises several coiled tube bundles (5) which are arranged in series and disposed in a common container (1), in which steam is generated and superheated thereafter. The individual tube bundles are separated from each other by interspaces (16) in which straight connecting tubes are arranged. Points which require inspection, and are possibly in danger of springing leaks, for example, the welded connections between the individual tube lengths, are positioned in these interspaces for easier accessibility. Furthermore in the same container are also tube bundles (21) arranged in which the steam is superheated. In the middle of the container a central tube (4) is arranged, in which the feedwater supply (6) is conducted, and which in operation closed by a blow-out disc (15), and which, if necessary can discharge the products of a liquid metal-water reaction. Special configurations of the feedwater distributors (8-11) are proposed, which enhance the safety of the steam generator in the case of malfunctions, for example, absorb the reaction forces of torn tube lines. Furthermore embodiments of the steam-collectors (27) are proposed which facilitate the inspection of the tube bundles.

Title: Active, media-free inertial guidance system - uses single stage friction wheel forming inertial coupling with variable power output revolutions
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G01C19/02
Filed: 1979-02-16
Abstract: An active medium-free inertial guidance system, e.g for aircraft, is simplified by the three stage bevel gear system being replaced by a single stage friction wheel system to form an inertial coupling with variable power output revolution rate. A spider, driven by a shaft perpendicular to it, has a hollow cylindrical foot fitting into a roller bearing in the bevel wheel and a hemispherical head driven by the shaft to cause friction wheel rotation. The friction wheel rotation and the input shaft rotation prod. an aligned steering moment about the neutral axis and rotation of a free wheel. The spider, which does not rotate about its longitudinal axis, and the steering moment generation combine to prod. a differential inertial torque converter drive including torque alignment.
