Title: Detector system for resonant circuit in identity tag - has search coil in null of field coils energised at varying frequency (NL 24.12.80)
Inventor: RUUMPOL GEURT J
IPC: G01S13/74
Filed: 1980-06-23
Abstract: Objects or persons to be identified are labelled with a tag containing a small resonant circuit, tuned to a frequency. In the range 10 to 90kHz. A pair of field coils (1A,1B) are connected in opposition and driven by a signal generator (2). This energises the field coils with a frequency which is swept over the range in 24 steps. A small search coil (3) is placed at the null point between the field coils, all three coils being in one plane. An identity tag in the vicinity distorts the field and produces an output from the search coil when the signal is on its frequency. The output is amplified and rectified (4) and applied, via a threshold (5) to logic processing circuits (6).

Title: Twin piston hydraulic pressure intensifier - has common slide valve and two other slide valves, serving each individual pistons
Inventor: STEIGER ANTON DIPL ING
IPC: F01L25/06
Filed: 1980-12-13
Abstract: The two pistons are subjected to a relatively low servo-pressure on their larger ends and generate a high pressure alternately in an operating medium at their smaller ends. The supply of the low-pressure medium is controlled by a slide valve (5) common to both pistons (30L,30R), with two further ones (31L,21L; 31R,21R) each serving one of them. Apart from a union (10) for the medium supply, the first valve (5) has six others (L1S,L2S,L3S;R1S,R2S,R3S). Three are connected to one of the individual valves and three to the other one. During a first phase, the medium is delivered from the feed union to one piston, so as to move it with its respective slide valve plunger, and during a second one to an end face (14) of the first valve also. During a third phase it is delivered to the second piston, causing it to start moving, and in a fourth one the supply to the end face (14) is cut off and instead delivered to the other end of the first valve.

Title: Device for dark field illumination in reflected light microscopes
Inventor: NEUPERT MANFRED DIPL PHYS
IPC: G02B21/10
Filed: 1981-01-12
Abstract: The invention relates to a light-guiding device which can be used in reflected light microscopes for beam guidance in the dark field illumination beam path. It is intended, in conjunction with a simple design, to eliminate the substantial energy losses due to radiation components that are absorbed or not used for the purpose of dark field illumination and which occur in the solutions that have so far become known and operate using light staircase arrangements or central diaphragms, as well as largely to reduce the impairment of the microscopic image due to interfering reflecting light. These shortcomings are removed by cross-sectional transformation of the dark field illumination beam by means of a fibre-optic light-guiding device, and by the arrangement of an annular lens directly at the exit face of the fibre-optic light-guiding device.

Title: Ductor roller drive on damping units
Inventor: JOHNE HANS
IPC: B41F31/10
Filed: 1981-03-18
Abstract: The aim of the invention is to find an uncomplicated ductor roller drive with which good controllability of the quantity of damping medium and a defined transfer of the damping medium and thus better printing quality can be achieved. The invention is based on the object of eliminating the joint play in the universal-joint shaft, even as a result of wear, in such a way that a positive-locking connection is produced from the drive via the universal-joint shaft to the ductor roller, and the torque can thus be transmitted without play. According to the invention, the object is achieved in that a torsion bar is arranged coaxially above the universal-joint shaft. The invention is also suitable for driving oscillating inking units for rotary printing machines. <IMAGE>
Patent DE-3125642-A1 (DE)
Title: Sealing device
Inventor: ELTER CLAUS DR ING
IPC: G21C7/16
Filed: 1981-06-30
Abstract: The invention proposes a sealing device between a cylinder, which can be moved axially or in rotation, and a wall which separates two gas- or liquid-filled spaces at different pressures (e.g. the interior of a reactor and a hydraulic device). The sealing device prevents mixing of the two media. This is achieved by the formation, between the sealing ring adjacent to the first space, the medium in which is subject to relatively small pressure fluctuations, and the second sealing ring, of a first annular space connected to a pressure line and the formation, between the second and the third sealing ring, of a second annular space connected to a vacuum or negative pressure line.

Title: Process for producing alkenes, dialkenes and aromatics
Inventor: BECKER KARL DIPL CHEM DR
IPC: B01J29/16
Filed: 1981-07-11
Abstract: The invention relates to a combined process for producing lower alkenes, dialkenes and monocyclic aromatics from hydrocarbon fractions whose main constituents boil above 200 DEG C, by a hydrogenation treatment and subsequent pyrolysis. While dispensing with the technologically expensive deep hydrogenation of the polycyclic aromatic raw material fractions, a hydrogenation product suitable for the pyrolysis can be made available which gives a quantity of cracked gas comparable with naphtha pyrolysis without increased occurrence of low-hydrogen carbon compounds. According to the invention, the bicyclic and oligocyclic aromatics are converted over NiO-WO3 catalysts on alkalysed alumosilicate by selective hydrogenation and mild hydrocracking of the cycloalkenobenzenes, which are partially formed as intermediates, into monocyclic aromatics alkylated up to 5-15% by mass. In the downstream pyrolysis, this hydro treated hydrocarbon mixture gives high total yields, specific to the raw material, of the target products, with only a little coke and tar deposits in the condensation zone of the pyrolysis furnace, it being possible to influence the ratio in which olefins and C6/C8 aromatics arise. Owing to their reduced content of sulphur compounds and nitrogen compounds, the liquid pyrolysis products have a high value in use.

Title: Method for transmitting information relating to the clearance of interference in telecommunications switching systems, in particular telephone switching systems
Inventor: HUTT HANS
IPC: H04M3/08
Filed: 1981-08-25
Abstract: The method for transmitting information relating to the clearance of interference in telecommunications switching systems, in particular telephone switching systems, provides that this information is input into a compact network-independent maintenance transmission device equipped with memories. Once a connection has been set up to the service centre, this information is serially transmitted there using a data transmission method. A connection can be set up either with a normal telephone set, the maintenance transmission device being acoustically coupled with the microphone of this set, or the maintenance transmission device itself serves to set up the connection, the device then being directly connected to a telephone line.

Title: Frisbee
Inventor: WESENBERG HANS-ULRICH
IPC: A63B65/10
Filed: 1981-12-11
Abstract: In a frisbee having a downward-curved and reinforced disc edge, the disc plane of which is completely flat, the weight ratio of disc plane to disc edge is a maximum of 3 to 4. With this and smaller weight ratios (3:5, 3:6, etc.), the gyroscopic effect stabilising the flying attitude of the frisbee is so great that the disc performs flights which are almost exclusively stable in direction, partly because it is particularly easy to cause it to rotate and throw it accurately (towards the catcher).

Title: Process for the drainage of washed laundry articles
Inventor: STUEHMEIER GUENTER
IPC: D06F51/00
Filed: 1981-08-06
Abstract: In the flow drainage of washed laundry articles, the laundry articles introduced into a cylindrical vessel having a lower screen floor and an upper cover are drained by means of a medium flowing from the top downwards. To avoid various disadvantages, before the flow drainage the laundry articles are drained to a residual moisture of approximately 50-45% by mechanical pressure and only thereafter are drained to a residual moisture of approximately 40 to 30% by means of an air flow, the mechanical pressure being maintained. The process can be carried out by the use of diaphragm-type drainage presses known per se, but appropriately modified, and having an annular diaphragm tube (17) arranged on the inner wall of the cylindrical vessel (11) and inflatable hydraulically in the direction of the vessel axis. <IMAGE>
