Patent DE-2548070-A1 (DE)
Title: Pulse regenerator responding to input pulses - functions at given time points passes pulses to output for duration of clocking
Inventor: BOEDEKER FRIEDRICH ING GRAD
IPC: H03K5/153
Filed: 1975-10-28
Abstract: The pulse generator detects the presence of a pulse at discrete time points quickly and passes it on to the output as long as clocking pulses are present. The regenerator is cheap, consumes little power and can handle low to very high clock frequencies. The input pulses (D) are applied to the base of a first transistor switch (T1) whose output is coupled to the input of a third switch (T3). A second switch (T2) is connected by its output to the second input of the third switch. The first and second switches each have two equal-ranking inputs and the third switch has three equal-ranking inputs of the second and third switches.

Patent DE-2605869-A1 (DE)
Inventor: HALLMANN WERNER
IPC: G04R40/00
Filed: 1976-02-13
Abstract: In order to evaluate a time signal in which a pulse is suppressed as time code (minute code) in a respectively periodically recurring fashion, accurate time gates are formed with the aid of a clock frequency. The code pulse (minute pulse) is evaluated as such only if a prescribed number of time signal pulses (second pulses) has previously arrived in the accurate timing code, and if the last, specifically only the last time signal pulse is lacking. <IMAGE>

Title: Measuring crimping of moving fibre tow - using predetermined formula and drawing off tow at specified tension
Inventor: REICHARDT MANFRED DR
IPC: D02G1/12
Filed: 1976-04-17
Abstract: Crimping of synthetic textile yarn tow is measured continuously using a formula E=left brace (vo-v1)/vo right brace x 110%, where E is the crimping of a tow having a titre of from 5-500 ktex, vo is the speed of uncrimped yarns and v1 is the speed of crimped yarns in that the crimped yarns are drawn off by a pair of feed rollers with a tension of 0.02-0.5 N/ktex, the stress being referred to the uncrimped yarns. Measurement is carried out in a destruction free manner and the values are accurately reproducible. Use of a large number of test samples is avoided.

Title: Carpet printing - with thickener applied and dried before the material is pattern printed
IPC: D06P5/00
Filed: 1976-04-17
Abstract: Printing of material lengths, partic. carpetings, is effected using an auxiliary agent before roller or spray pattern dyeing, when the material is subjected to steam to fix the dye. Before printing, the thickener or other auxiliary agent is applied, and any water removed and dried before printing. Process ensures that the dye of the printing penetrates to the base of the fabric pile structure giving a clear printed pattern.

Title: Anti:icing equipment for aircraft control surfaces - has aerofoil in front of surface to accelerate airflow without affecting aerodynamics
Inventor: ANTONOV OLEG KONSTANTINOVITSCH
IPC: B64D15/00
Filed: 1976-06-02
Abstract: The anti-icing equipment for aircraft aerodynamic sufaces, esp. horizontal control surfaces, is an aerofoil (4) running the full length of the surface (2), mounted parallel to it on struts (12) projecting forwards from it's leading edge (5). The aerofiol's chord (8) is 3-8% of the main surface chord and inclined to the plane (10) of the latter at between 30 and 60 deg. (9). More of the aerofoil is below the main surface centre-line than above it. The gap (11) between aerofoil nose and main surfacae leading edge (5) is 1-3% of the latter's chord. The aerofoil's shape causes airflow acceleration over the main surface leading edge, discouraging icing, without affecting aerodynamic characteristics.

Title: Narrow metal profile with asymmetrically positioned channels - is extruded and bored with final drawing to size
Inventor: HOLTORD FRANZ JOSEF ING GRAD
IPC: B21C37/15
Filed: 1976-06-16
Abstract: Themetal profile with asymmetrically positioned longitudinal channels is made by extrusion or rolling. These profiles are used in high performance electrical machines which requires internal cooling. The profiles with cooling channels are made with high dimensional accuracy. A solid block is produced in first stage by extrusion or rolling. The cross section of this profile corresponds almost to that of the finished profile. Subsequently through holes are made into the solid blocks. The bored block cross section dimensions are reduced subsequently by rolling or drawing through a die. Mandrels are placed into the holes and kept there during this reduction process. The bored holes are sized by pulling mandrels through them. The bored block is subjected to several heat treatments on drawing.

Title: Fire retarding seal for cable feedthrough - has cables surrounded by loose granules that expand when heated
IPC: H02G3/22
Filed: 1976-07-17
Abstract: The fire-retarding seal, for a cable feedthrough passing through a wall in a building, consists of sodium silicate granules or another material that expands when heated packed inside a foamed asbestos bag surrounding the cables. The bag is located in a metal box and closes off the open ends of the box through which the cables pass. The box is located in the hole in the wall (or ceiling) and closed with screw down lids. The advantage of using an expanding material lies in such material being loose enough at normal temps. for cables to be pushed through it relatively easily. The material only becomes gas tight when it expands due to heat.

Title: Detecting explosive cartridges after failure of detonation - using a magnetometer to indicate magnetic components
Inventor: WOEBKING HANS DR
IPC: F42B3/00
Filed: 1976-12-17
Abstract: Explosive cartridge contains magnetic components, pref. consisting of steel in the form of a cylindrical sleeve which is filled with the explosive material. When several charges are ignited simultaneously, the ones which fail to detonate can be reliably detected, with a simple magnetometer, e.g. a flux gate magnetometer or a Hall probe. Tubular shape generates max. external magnetic field with a small pole area and hence low vol. The magnetised steel tube is surrounded by soft explosive material, and therefore protected against hard impacts which could lead to demagnetisation.

Title: Shell for car body - has cross brace above gutter and seal flange for use in hatch back version only
Inventor: HASLER FRANZ
IPC: B62D25/08
Filed: 1976-12-22

Title: Voltage monitor which applies clock pulses - is coupled to reference voltage at operational amplifier input to detect tolerance deviations
Inventor: SCHMIEDCHEN HARALD
IPC: G01R19/165
Filed: 1977-05-11
Abstract: The voltage monitor checks the upper and lower tolerance limits of a voltage using an ac signal or a clock signal. This is achieved by applying the voltage (U) to be monitored between OV and the non-inverting input of an operational amplifier (2). A reference voltage (UR) is applied via a resistor (7) and two antiparallel diodes (4,5) to the inverting input. The clock signal (+ DELTAU) is used as bias voltage for the diodes and is applied to them via a dc blocking capacitor (6). The sign of the output voltage (UA) depends on whether the input voltage exceeds or falls below the reference. Potentiometers can be used to set the tolerance range and the reference independently.
