Patent DE-3117687-A1 (DE)
Title: Measuring method for determining optical or electromagnetic properties of measurement objects
Inventor: KUEPPER ECKHARD DR RER NAT
IPC: G01N21/21
Filed: 1981-05-05
Abstract: A measuring method is specified for determining optical or electromagnetic properties of measurement objects, in which a measurement object is inserted into the beam path of a polarised electromagnetic radiation and the radiant power of the transmitted or reflected radiation or of a scattered radiation is measured. In order to permit the optical or electromagnetic properties of the measurement objects to be comprehensively determined in a simple way, the direction of polarisation of the incident beams, or the measurement object is rotated continuously or intermittently about the direction of radiation, the radiant power is subsequently measured as a function of the angle of rotation, and a compensating curve of a suitable material type and having a prescribed number of coefficients is matched to the measured values. <IMAGE>
Patent DE-3120486-A1 (DE)
Title: Manually operated valve
Inventor: LIVET JEAN
IPC: F16K35/16
Filed: 1981-05-22
Abstract: The valve has a shut-off device (7) which presses the flap (9) against its seat (13) under the influence of a spring (8). The displacement of the shut-off device (7) as a result of operating the lever (18) can take place only when the magnetic core (32) is drawn to the left, the shaft (35) thereby displacing the part (26) against the pressure of a bush (38) on which a spring (39) acts. If the lever (18) is now operated, the shaft (20) pushes the part (26) downwards, which for its part pushes the shaft (30) in order that the spring (8) can move the shut-off device (7) downwards. The part (26) is subsequently locked by latching its retaining edge (42) in under the edge of a pin (40). In the event of an interruption in the excitation current, the core (32) and the part (26) return to their original position, as a result of which the moving part (26) and the shaft (30) are released. The spring (31) then guides the shut-off device (7) back into the position shown. <IMAGE>

Patent DE-3131543-A1 (DE)
Title: Laundry dryer with a condensation device
Inventor: MAIER ROLF
IPC: D06F58/24
Filed: 1981-08-08
Abstract: A laundry dryer with an air-cooled condensation device arranged in the drying-air stream requires only the presence of an electrical plug socket in order to operate. The condensate occurring during the drying operation is fed from above, by way of a free-flow stage, in a condensate-collecting container arranged at an easily accessible point in the front region of the dryer housing. The condensate-collecting container should be emptied after each drying operation and, for this purpose, must be arranged so as to be easily removable. So that, if emptying is forgotten, the condensate-collecting container does not overflow in the subsequent drying operation and cause water damage, the water level in the container must be monitored. The monitoring means consist of a switching member which is arranged in the condensate-collecting container and is influenced dynamically by the water level in the container and which is in touch contact with an electrical switch arranged outside the condensate-collecting container and having at least one on/off switching position, and of a limit switch arranged in the dryer housing and interrupting the drying programme when the condensate-collecting container is not inserted. With this monitoring device, no electrical or water-carrying connections have to be detached during the extraction of the container.
Patent DE-3135872-A1 (DE)
Title: Method for the autoinfusion of water and/or nutrient solutions in cuttings for the purpose of economic woody plant propagation
Inventor: REIF FRIEDRICH
IPC: A01G7/00
Filed: 1981-09-10
Abstract: The invention relates to a method to be used for vegetative woody plant propagation by leafless or leafed softwood or hardwood cuttings - conifer included - from spring to autumn. The vegetative propagation method, which has now become the most important one, is, however, from plants which root easily, by no means without problems because the unrooted shoot lives entirely on the food contained in the shoot, which is naturally limited. An additional factor is the continuous water loss which not uncommonly leads to "parching" of the plant. The method according to the invention counteracts this circumstance by pushing or placing on top of the upper cut(s) of the cuttings for example a piece of tubing or a hollow body which fulfils the same purpose, sealingly around the periphery of the shoot, and this, filled with water and/or nutrient solution, takes over the supply of nutrients to the cutting by autoinfusion. The total supply to the shoot achieved in this way makes it possible to use cuttings of unequal length and even those which are difficult to root, and these develop remarkably quickly. <IMAGE>

In further development of the subject of the invention, the highly transparent drawing paper is coated, laminated or made up on one or both sides with a mat or glossy microfilm, or is coated or laminated on one or both sides with a mat or glossy lacquer or is protected on one or both sides by acrylic or glass plates or is embedded therein.
Patent DE-3140759-A1 (DE)
Title: Monitoring device
Inventor: HOMANN NORBERT
IPC: G05B19/4065
Filed: 1981-10-14
Abstract: Semi-automatic and fully automatic machine tools generally have several tools which, during an operating cycle for machining a workpiece, act at certain staggered intervals on the workpiece. As a result, the tools are subjected to varying stresses, which leads to varying productive output among the tools. The monitoring device serves to monitor and indicate the moment at which the individual tools should be exchanged. For each tool there is a desired-output store and an actual-output counter, the values of which are continuously compared with one another by a comparator. When the values coincide, the comparator transmits a tool-change signal. A total-output counter counts the total productive output for each individual tool position. A tool-change counter counts the number of tool changes. From these two values, a dividing device calculates the average productive output for each tool position as an indication of whether the tools always reach the desired productive output or whether a change in the desired value or the workpieces or the tools is necessary. For the individual representation of all these values there is a multiple display field which can alternatively be connected via a selector switch to the stores and counters as well as analysing circuits for the individual tools.

Patent DE-3205262-A1 (DE)
Title: Injection-moulding machine
Inventor: REES HERBERT
IPC: B29C45/04
Filed: 1982-02-15
Abstract: A four-sided turret head, mounted between a fixed jaw and a movable jaw of an injection-moulding machine and fitted on a carriage such that it can slide in the direction of movement of the rolls, can be turned perpendicularly with respect to this movement into four working positions, spaced apart by 90 DEG ; in each of these positions, in which one or more cores carried on a side face penetrate into corresponding recesses of an opposite counterplate on the fixed jaw, whereas a corresponding core or a plurality of cores are received on an opposite face in a counterplate on the movable jaw, the turret is positively operated by two aligned bolts on these plates; when the mould is closed, these bolts enter corresponding bores in the turret. This closing is conversely prevented by the bolts until the turret is in the correct position. The core or the cores on each turret face can cross over a corresponding stripping plate, which lies on this face, or ejecting bolts on a corresponding movable holding plate may penetrate into the said plate. Once a workpiece moulded around a core of each of these faces has been turned through three rotational positions, rollers connected to the associated stripping plate are taken up during the mould closing stroke by a pair of cam sticks on the two plates carried by the rolls, in order to release the cast workpiece from its core. <IMAGE>
Patent DE-3213304-A1 (DE)
Title: Clip suturing apparatus
Inventor: OKUN GUENTER
IPC: A61B17/072
Filed: 1982-04-08
Abstract: The invention specifies a clip suturing apparatus in which the clip magazine has at least one transparent region through which the number of clips present in the clip magazine can be established simply by inspection. A missing clip can be detected in this way without any problems. Use of a polycarbonate plastic, especially a polycarbonate of bisphenol A permits, on the one hand, a check by inspection of the number of clips by transmitted light and, on the other hand, sterilisation of clip magazines which are no longer sterile by heating without loss of the dimensional stability. A delimiting element having a handle and a hook can be used to remove the counter-pressure plate and the clip magazine reliably and without difficulty from the clip suturing apparatus.

Patent DE-3224854-A1 (DE)
Title: Heat store
Inventor: FELDGRILL FRANZ
IPC: F28D20/00
Filed: 1982-07-02
Abstract: A heat store, in particular for storing solar energy and industrial heat, consists of an inner, first heat store part (1) and a second heat store part (2) surrounding the same. The first heat store part (1) is filled with a heat storage compound (11) which melts at between 30 and 120 DEG C (e.g. paraffin), and the second heat store part (2) is filled with earth (14). The first heat store part (1) is insulated by the second heat store part (2), so that even after long storage times high temperatures, e.g. for hot service water, still prevail in the first heat store part (1). A control device ensures that the heat transfer medium that is heated by the energy source firstly heats the earth (14) and does not heat the heat storage compound (11) in the first heat store part (1) until the heat transfer medium heated by the energy source has reached a higher temperature than that of the heat storage compound (11). <IMAGE>
Patent DE-3227577-A1 (DE)
Title: Position measuring device
Inventor: PETSCHENKA EDWIN DIPL ING
IPC: G01D5/347
Filed: 1982-07-23
Abstract: In this digitally incremental position measuring device a rotatably mounted disc (1) of optically transparent carrier material is provided with an external stroke pattern ring (4), a central, flat wave winding (3) and an internal commutator segment ring (2). The detection of position is performed with the aid of the external stroke pattern ring (4) by modulating the luminous flux from a light source (12) to an optical receiver (13). The position measuring device permits detection of speed at the same time as detection of position. For this purpose, there is provided in the interior of the housing (11) a permanent magnet (9) whose magnetic field induces a speed-proportional voltage in the wave winding (3) as the disc (1) rotates. This voltage is tapped via the internal commutator segment ring with the aid of carbon brushes (5). In order to increase the number of turns of the wave winding (3), the disc (1) is preferably assembled from a plurality of individual coils coated with copper in each case, and plated-through holes (19, 20) are provided at the starting and end points of the commutator segment ring (2) and the wave winding (3). The combined position and speed sensor can be used, eg, in drive motors. <IMAGE>

Patent DE-3231893-A1 (DE)
Title: Rapid closure device
Inventor: LUTZ EDGAR
IPC: F16B5/10
Filed: 1982-08-27
Abstract: The invention describes a rapid closure device by means of which flat workpiece parts can be mounted in a captive manner on one another, especially under-floor cladding on a motor vehicle. The new rapid closure device permits pre-installation on one of the two workpiece parts and is constructed as a structural unit. The operation of a clamping element which engages on the rear side in order to spread two sprung limbs takes place via separated engagement surfaces, so that it is possible to release it or lock it without any tools. The rapid closure device latches in place in the locking position and thus permits a connection between the two workpiece parts which is captive and is easy to produce, it also being possible to compensate for tolerances in the case of passage openings which are not precisely aligned. The novel rapid closure device offers the advantage that, for example, under-floor claddings can be applied to motor vehicles such that they are captive and using a single workman.
