Title: Splicing multicore optical cables - using manipulator to align ends with laser pulse reflectometer for accurate determn. of joint.
Inventor: LIERTZ HEINRICH DR ING
IPC: G01M11/00
Filed: 1980-05-20
Abstract: The splicing of multi-core optical cables is achieved by means of an impulse reflectometer situated at the measuring end of the cable, the opposite end of which, (splice and), is to be connected with another multicore cable, core for core, e.g. by welding. A manipulator is provided at the measuring end, for arranging the cable ends in V-shaped grooves, side by side, and preparing these ends, for connection to the reflectometer (RM), which contains a laser transceiver, and must be coupled to the conductors individually one after the other, via a lens. This is carried out by the manipulator, which is movable in three coordinate directions. Each conductor is aligned to a max., the relevant coordinates being stored. A second phase of the procedure entails establishing the time situation of at least two scanning impulses and storing these, so that in the third measuring phase, the measured and stored coordinate values of the first manipulator are called up and adjusted for the individual light conductor. This enables the splice to be accurately positioned with the help of a second manipulator at the splice position, and allows the whole procedure to be carried out by one person.

Title: Pressure pulse detection apparatus - eliminates pulses from mud pump and enhances pulses from downhole equipment
Inventor: CLYCOMB JACKSON REYNOLDS
IPC: E21B47/18
Filed: 1980-06-10
Abstract: A mud delivery system used in drilling an oil well has mud delivered from a pump through a pipe connected to a drill string extending to a downhole signalling apparatus. Signals are propogated up the mud column standing in the drill pipe. An apparatus is arranged to measure and null to a minimum value variations in mud flow velocity and pressure from the mud pump traveling through the mud column. An output signal is formed representative of variations from the downhole signal apparatus. Pref. there are arrangements for measuring pressure and velocity variations in the mud column and forming output signals. Weighted portions of these signals are summed and an output sum formed where mud pump noise is accompanied by pressure and velocity increases which are weighted and summed to cancel a range of specified variations. Signals from the downhole signalling apparatus are summed and weighted resulting in additive enhancement. With the apparatus of the invention the pump pressure pulses are eliminated while pressure pulses from the downhole equipment are markedly increased.

Title: Piezoelectric coupling suitable for remote control - communicates between input master oscillator and output circuit based on acoustic waves
Inventor: SCOTT KENNETH CLIVE
IPC: H03K17/94
Filed: 1980-07-31
Abstract: An oscillator circuit includes a piezoelectric oscillator as the master, a feedback circuit for the oscillator circuit and a coupled output circuit without direct electrical contact. Both the feedback circuit and the output circuit contain piezoelectric elements with electrodes which are coupled to the oscillator of the oscillator circuit through acoustic waves. This creates a simple and effective coupling by high-efficiency piezoelectric elements, with excellent insulation between input and output circuit. This makes it ideal for certain remote control applications. An input oscillator circuit (11) includes a piezoelectric element (12) which produces acoustic signals and transmits them to an output circuit (13). A capacitor (C1) smoothens the input d.c. voltage, and the resistors (R1,R2) produce the bias for the transistor (TR1). Its collector and emitter are connected to the electrodes (E2A,E2B) where they produce acoustic waves. Electrodes (E1A,E1B) produce a positive feedback in the base- emitter circuit. The electrodes (E3A,E3B) feed the output circuit which can include a triac.

Title: Combined binary adder and subtractor circuit with octal display - has two rows of stores having off-set input controls
Inventor: MERKLE PAUL
IPC: G06F7/509
Filed: 1980-08-16
Abstract: The adder and subtractor circuit working in binary code includes an octal display, an octal to binary input encoder and a binary to octal output decoder. A combined adder and subtractor is realised more simply than with a decimal-BCD adder and subtractor. The arrangement uses feedback connectors (D) and can use two or more rows of stores into which the potential series of the result are fed using control pulses offset in time. The special adder consists of an optional number of adder decades, each contg. three full adders (VA), six storage flip-flops (2), a decoder circuit (3) and two octal-to-binary encoder circuits. A special subtractor can be formed by replacing the full adder circuits with full subtractor circuits.
Patent DE-3037810-A1 (DE)
Inventor: NELLE GUENTHER DR ING
IPC: G01D5/36
Filed: 1980-10-07
Abstract: An incremental length or angle measuring instrument includes a scale having a line grid and a plurality of reference marks. A scanning unit is provided with a plurality of photosensors to scan both the line grid and the reference marks. A reference mark selecting arrangement is described which includes a light source and a photosensor. This selecting arrangement acts to select a subset of the reference marks from the total number of reference marks and to bring only this selected subset of reference marks into operation. This selection takes place through the allocation of a light source or a reflecting element to each of the selected reference marks. The scanning unit operates to generate two square wave scanning signals, a reference signal in response to the reference marks and a selection signal in response to the presence or absence of the light source or the reflecting element associated with the selected reference marks. A logic circuit is provided which is responsive to the reference signals and to the selection signals such that a control signal is generated by the logic circuit only if both the reference signal and the selection signal are present simultaneously. The light sources or reflecting elements which serve to designate the selected reference marks can arbitrarily be moved as necessary such that the selected subset of reference marks can be freely and arbitrarily chosen from the total number of reference marks readily and without alteration of the scale itself.

Title: Controlling iron ore sintering plant - by computer using permeability measurement to control burn-through position
Inventor: HASLMAYT JOHANN DIPL ING
IPC: C22B1/20
Filed: 1980-11-06
Abstract: In the sintering of fine grained iron ore, which has been mixed with fuel, lime, water and recycled material, by feeding the mixt. onto a sinter belt or travelling grate and igniting its surface under an ignition hood while passing oxygen-contg. gases through it, the gas permeability of the mixt. is measured immediately after the required layer height has been formed and before it passes under the ignition hood. The measurement is fed into a computer which calculates the expected position of the burn-through point according to chemical analysis, mass flow and moisture content of the mixt. and process parameters such as belt or grate speed, coke requirement, layer height, recycle material ratio and water addn. The computer then compares this position with the required position near the last suction box at the output end of the belt or grate and alters at least one process parameter if there is any difference in the positions. Method gives an effective feed-forward control with no dead time resulting in uniform sinter quality in spite of variations in the feed mixt. No variation of the feed mixt. to alter its permeability, is required.

Title: Mobile floor heating
Inventor: COLLET WERNER
IPC: F24D3/16
Filed: 1982-02-02
Abstract: Caravan and travelling mobile accessory as well as partly heating construction accessory. Heating installations using the most varied systems are offered especially for camping vehicles. They do not, however, satisfy the requirements which make comfortable accommodation possible in the cold season. Test results clearly show that although these heating installations produce up to 28 DEG C at table or head height, it remains cold in the floor region. In this case, only floor heating can provide a remedy. As this can be brought about subsequently only with very high rebuilding costs in the already built camping vehicles, only a mobile floor heating system can solve the problem. A pipe or tube coil is installed in a panel, box or frame construction and flowed through by a preheated medium and thus heats the floor region. The device is portable and can be installed in any place (Fig. 1). The mobile floor heating system can be used everywhere where it is cold to the feet, e.g. in camping vehicles, sales stands, butchers' shops etc.

Title: Method in the production of a paper-machine stone roller
Inventor: VESTOLA JUHANI
IPC: D21F3/08
Filed: 1982-03-05
Abstract: In the production of paper-machine stone rollers, a significant disadvantage which has been observed is that bending occurs in a stone roller which has been ground completely straight and finish-polished. These bends are very disadvantageous in the operation of the stone roller if it is used as a press roller since the bends cause a non-uniform press pressure distribution which manifests itself in a non-uniform moisture profile of a web treated in the press. To eliminate these disadvantages, the invention describes a method in the production of a paper-machine stone roller, in particular a press roller, in which method the bends which occur during the operation of the stone roller are reduced or eliminated. In the method, the cylinder shell (10) of the stone roller is ground to its final form at a temperature which corresponds essentially to the prevailing operating temperature of the stone roller concerned in the paper machine. This temperature is generally about 35...55 DEG C.   <IMAGE>
