Patent DE-3034923-A1 (DE)
Inventor: SCHROTZ KURT
IPC: B41K1/10
Filed: 1980-09-16
Abstract: This invention relates to a belt printing mechanism with parallel mounted endless type belts which carry on their exterior surface print types. These type belts extend around an adjustment wheel and a plurality of star wheels where the star wheels are rotatable about a shaft where each star wheel has four corners. A catch mechanism is held under tension against the star wheels and holds these in predetermined detent positions to prevent free rotation of the star wheels. When printing multi-character symbols, the selected print types of adjacent type belts must be brought into predetermined printing positions. In order to assure a clean print copy, care must be taken that the print types rest in the exact same line height. In order to accomplish this, the catch mechanism for each star wheel is provided with a spring tongue which touches at least two separated points of the perimeter of its associated star wheel between two adjacent corners thereof. The plane of each spring tongue with respect to the plane in which its associated star wheel rotates is an acute angle. When the type belts are adjusted, the catch mechanism generates pressures which are clearly recognizable by the operator and which simplify the procedure of bringing the print types into their predetermined printing positions.

Title: Process sequence electronic delay control - has clock pulse controlled counter whose capacity is regulated by storable control signal
Inventor: KRINGS GERT DIPL ING
IPC: G05B19/042
Filed: 1980-09-30
Abstract: The control is effective after a passage of a preset delay time, allocated to a respective process step. A clock pulse controllable counter with adjustable capacity forms a delay circuit. The control signal, supplied to the counter for its capacity adjustment, can be stored in a control signal memory. After the delay time a pulse appears at the counter output and is transmitted to a read-out for the control signal from the memory. The recovered signal serves as a control criterium for the process step to be initiated. Pref. the counter output is transmitted to an interrupt input of a microprocessor. The electronic control may be applied in a remote control station. After a first delay time an excitation message can be triggered, while after a second delay time the control may trigger a new start for the sequence control.

Patent DE-3041382-A1 (DE)
Title: Cold inert gas produced esp. for mines and quarries - from combustion gases sprinkled with water then cooled to condense water
Inventor: LINDE ROBERT VON DIPL ING
IPC: B01J19/14
Filed: 1980-11-03
Abstract: Cold inert gas is produced by burning fluid fuel, then cooling the combustion gases. The hot combustion gases are subjected to direct water contact and produce a humid vapour stream, typically at approx. 88 deg.C, having a dew point higher than the combustion dew point. This stream is air-cooled to below the dew point of the combustion gases, typically to 5-10 deg.C above ambient temp., and the condensed water is then recycled into the hot combustion gases. Process is used in partic. for the prodn. of large quantities of inert gas as required, i.e. in mines and quarries, more specifically, in remote areas where water supply is not available or difficult. The arrangement enables the water to be recirculated with an absolute minimum of make-up and utilises approximately 96% of the heat produced in the burner for evaporating the water in the circuit. The resultant gas stream may be produced at rates of several thousand m3 per hr.

Title: N-alkene(s) mixed with hydrogen isomerised to I-alkene(s) - by halide-doped alumina or silica catalyst continuously regenerated
Inventor: MUELLER HANS JOACHIM DR
IPC: B01J27/06
Filed: 1980-12-23
Abstract: i-Alkenes are prepd. catalytically from n-alkenes in presence of H2 at a temp. of 400-600 deg.C. The catalyst is prepd. by copptn. of hydrated Al2O3 and/or SiO2 with NH4 salts, calcining (with loss of the latter) to give activated Al2O3 and/or SiO2, and then doping with a halide of Periodic Gps. IIIa-Va, IIb-VIIb or VIII, and/or of H. After activity loss, the catalyst is regenerated by an O2-contg. gas and a halohydrocarbon at a temp. of 400-800 deg.C.; by using a mobile bed, e.g. a fluidised bed, a purged catalyst stream may be regenerated continuously or discontinuously. Used for treating e.g. 4-8C, pref. 4-5C, esp. 4C n-alkenes and mixtures contg. them, e.g. the 4C prod. stream from steam cracking after removal of butadiene and i-butene. Yields and conversions are high. Catalyst regeneration does not require process interruption.

Title: Method for the visualisation and optical detection of corona discharges
Inventor: IGENBERGS ERIK DR
IPC: G03G17/00
Filed: 1981-03-26
Abstract: The analysis of the corona discharge of objects carrying a high voltage is - in addition to applications in materials testing and strength testing - increasingly used also in medicine: for example, the corona of the fingertips allows, under certain conditions, conclusions to be drawn regarding the physical and psychic state of the patients. A high-voltage generator (1) suitable with regard to voltage and frequency for the particular application is connected to an electrode (1) which consists of a glass plate, on one side of which a transparent, electrically conductive layer has been vapour-deposited. The object (3) to be investigated is placed upon the uncoated side of the electrode (2) and connected (10) to the second pole of the high-voltage generator (1). The corona discharge can then be detected visually, photographically or electronically in its entirety through the coating of the electrode and the glass plate acting as a dielectric. The chemically and electrically neutral behaviour of the dielectric allows a reproducible application of this method. The material used for the optical detection of the corona does not itself come into contact with the electrical discharge. <IMAGE>

Title: Capacitance probe for contactless measurement of wire capacitance in extruder plants
Inventor: SITTIG KONRAD
IPC: B29C48/92
Filed: 1981-03-30
Abstract: The probes presently used in the cable industry for the purpose of measuring capacitance on running wires mostly consist of bore probes which are arranged one inside another and connected to one another electrically to form half bridges. In conjunction with the use of brass tubes, this system and the additional requirement for watertightness render these designs very expensive. The aim of the invention is to simplify the design and production of the probes. The solution is that the electrically conductive cooling channel in which the probe is located is included in the measurement principle, the probe consists only of two mutually insulated tubes, and the wires to be measured are electrically earthed with the cooling channel. An insulation film over the probe protects against external electrical influences.
