Title: Device for recording the conveyance of liquid in the inking and damping unit of printing machines
Inventor: WIESNER REINER DIPL PHYS
IPC: B41F33/00
Filed: 1983-06-08
Abstract: The invention relates to a method and a device for the visual recording of the special features which characterise the production of layers of liquid by the process of liquid separation. These features, i.e. the liquid lamellae, threads and droplets, only occur when the separating operation is proceeding and are influenced during this process by different parameters, such as the layer thicknesses, the mixing ratio, the viscosity, etc. The recording, according to the invention, of the light scattered over these features therefore provides a measure which directly characterises the operation of liquid separation and can be used for the locally restricted monitoring or control of said process. In this case, it allows, in particular, the parameters which influence these features to be measured, i.e. the layer thicknesses or the mixing ratio, etc. Layers of liquid are produced by the process of liquid separation, in particular in printing machines and varnishing and gluing machines. The invention can be applied advantageously on machines of this type. It can be used specifically in offset printing machines for checking the quantity ratio of the printing ink to the damping medium.

Title: Combinable trailer
Inventor: HEIN KURT
IPC: B60P3/34
Filed: 1983-07-29
Abstract: A combinable trailer for transport and for use as a tent base or as a camping trailer has detachably fastened, folding-over or displaceable panels which, in the converted state of the trailer, serve as a sleeping surface within a tent which is to be coupled on. The conversion of the trailer into its function as a base element for a tent can be executed simply. Folding-over supplementary panels serve to enlarge the individual sleeping surfaces so that the sleeping surfaces are not limited to the interior of the loading case. In this way, a trailer is provided which can be advantageously used as the base or in combination with a tent base, it being easy to vary the sleeping surface. It is only necessary to place the inner tent onto the dimensions of the base area of the trailer; the outer tent can be of a conventional, commercially available type.

Title: Shuttle race
Inventor: PRINCIPE VICTOR
IPC: D05C11/18
Filed: 1983-10-06
Abstract: The shuttles (S) of embroidering and quilting machines move on a shuttle race consisting of a baseplate (1) which is connected firmly to a support (2). The shuttles (S) are guided laterally by longitudinal cheeks (4). A needle channel (6) extending perpendicularly to the longitudinal direction is embedded in the sliding surface (5) of the baseplate (1), approximately in the middle of the latter. To prevent the shuttles (S), which have a concave ground portion on their bearing surface, from butting against the needle channel, a groove-shaped recess (10) extending upwards from the needle channel is made. The recess (10) ensures a better reception of the needle-thread loop thrown up by the needle (7) and a more exact guidance of the shuttle on the sliding surface (5). <IMAGE>

IPC: E04C2/22
Filed: 1983-12-16
Abstract: Webs for reducing bending in board-shaped construction elements when in use have their main direction of load perpendicular to the board plane. The devices have a sandwich of at least one first material layer, one second material layer, and one third material layer. The third material layer lies between the other two material layers and has a substantially higher coefficient of heat expansion than the other two material layers, so as to set up contracting biasing forces in the third material layer. The third material is made of a sheet metal strip. The two other materials are made of thermosetting plastic, which sets at a temperature considerably above the working temperature of the construction element.
Patent DE-3347248-A1 (DE)
Title: Proportional control valve
Inventor: ZIMMERMANN FRANK DIPL ING
IPC: G05D16/20
Filed: 1983-12-28
Abstract: The invention relates to a proportional control valve (1) for producing a fluid-medium pressure controlled as a function of the position of a control piston (10) adjustable against a restoring spring (16) by auxiliary-force actuation. In this arrangement, the control piston (10) is to have at its periphery control edges (31, 32) for the position-dependent adjustment of the fluid-medium control pressure with the use of an admission pressure fed via a first connection (29) and an ambient pressure fed via a second connection (23). In order to obtain effective sealing of the admission pressure in such control valves in the inoperative position, that is, when the auxiliary-force actuation is switched off, the control piston is to be connected to at least one closure means (19) which, when the auxiliary-force actuation is switched off, tightly closes a passage cross-section for the working medium under the admission pressure. Here, the closure means can be formed by a sealing face (20) on a valve part (19) connected to the control piston (10). The sealing face (20) can be acted upon by the restoring spring (16), acting on the control piston, in order to tightly bear against a sealing seat (21) allocated to a passage cross-section of the admission pressure. <IMAGE>

Title: Stabilised power supply device for television receivers
Inventor: SECKENDORF WILFRID
IPC: H02M3/335
Filed: 1983-12-29
Abstract: The invention relates to a device for generating the feed voltages for the electrical assemblies of a television receiver. It is the object of the invention to develop a stabilised power supply device with a freely oscillating flyback converter in such a manner that all electrical assemblies and the picture tube of a television receiver are supplied from the rectified mains alternating voltage with as low as possible power conversion losses and additional expenditure for suppressing a modulation of the high tension when using a dynamic east/west raster correction is avoided. This is achieved by the flyback converter transformer being provided with an additional secondary winding which is connected to the acceleration electrode of the picture tube, all windings of the transformer being arranged on one leg of a U-shaped ferrite core in such a manner that the primary storage inductance is placed between the secondary windings for generating the feed voltages for the electrical assemblies and the additional secondary winding, and that windings with numbers of turns which are low in comparison with the width of the winding are wound with such a pitch that they largely enclose the ferrite core over the entire useful winding width, and that the winding voltage induced during the flyback phase is two to three times greater than the winding voltage during the conducting phase of the switching transistor. <IMAGE>
Patent DE-3400943-A1 (DE)
Title: Mortise lock equipped with a bolt
Inventor: HOLDER MICHAEL
IPC: E05B63/20
Filed: 1984-01-13
Abstract: In a mortise lock conforming to recent requirements and having an inner or an inner and an outer door handle and a rotary cylinder lock, the invention affords the advantage of complete security as a result of the automatic shooting forwards of the lock bolt when the door is slammed shut. The blocking of the door handle or door handles by button pressure prevents the possibility that children will leave the house without permission, or ensures complete security with a lock having two door handles, for example in office doors, etc. The use of a key for the secure locking of the door proves to have been overtaken. If the door handle is not blocked, the door can be opened by means of the door handle, otherwise the door is opened by the actuation of a rotary cylinder, the blocking of the door handle being cancelled at the same time. Furthermore, it can be seen that there is the advantage that the house owners, employees, etc. are compelled to withdraw the key, since automatic locking does not otherwise take place. The door is obviously open and the house owners, employees, etc. notice that the key is still inserted.
Patent DE-3403274-A1 (DE)
Title: Popular entertainment device in the form of a figure-of-eight track
Inventor: SCHWARZKOPF ANTON
IPC: E01B25/24
Filed: 1984-01-31
Abstract: The development of popular entertainment devices in the form of figure-of-eight tracks with passenger carriers suspended and guided on the continuous track system has in practice led to hitherto unsolvable problems because, during high-speed travel through curves, rocking motions arising under the action of the centrifugal force, despite damping measures, have led to hazardous breaking stresses. In order to overcome these problems, the invention proposes that the individual supporting rod (2) of the passenger carrier (1) be suspended in a running-gear frame (12) to be capable of a pendulum movement, the running-gear frame (12) having mutually connected transverse and longitudinal supports (16, 18), and running and guiding rollers (5, 6) of the running gear (4) being mounted thereon in an articulated manner, combined to form structural groups. The damping arrangement is provided between the supporting rods (2) and the running-gear frame (12). The effect of this is that the running and guiding wheels (5, 6) can freely adjust to the position of the rail (9, 10, 11) and the forces arising from the damping or avoidance of the rocking motion are distributed over all the running and guiding wheels (5, 6). <IMAGE>

Patent DE-3407601-A1 (DE)
Title: Folding machine
Inventor: SCHAUER ERICH
IPC: B65H45/12
Filed: 1984-03-01
Abstract: In order to improve access to the sheet adjusting devices and to facilitate removal of defective sheets for different machine widths with an arrangement of the folding knife assemblies provided in combined folding machines which is as rigid and as free of vibration and twisting as possible, the folding knife assemblies with feeding devices are mounted on a rigid frame ridge, which extends between and is attached to frame side walls, at the outlet end of the machine frame and the frame side walls are provided with deep recesses which extend over the region of the folding knife assemblies. As a result of these recesses, the operator has a good view of the adjusting elements, which are now to remain easily accessible. This also applies to the cutter spindles or outlet spindles with transport rollers and cutting or perforating devices arranged at the outlet of the buckle folding assembly used for parallel folding. Sheet adjustment and removal of defective sheets can be carried out more quickly and easily than in designs known to date. The arrangement of the frame bridge also makes it possible to drive the folding knife assemblies supported by it using a common drive, in a coupled fashion, for example using a toothed belt driven parallel to the plane of the frame bridge by an electric motor mounted on the frame bridge. <IMAGE>

Title: Flexurally rigid corner connection
Inventor: FAHLE HEINZ
IPC: E04B1/26
Filed: 1984-04-06
Abstract: A description is given of a flexurally rigid corner connection for timber constructions or timber/steel constructions and the like. The corner connection is distinguished in that it exhibits a special connecting element in the form of a plate which is fastened on the crossmember or the support of the corner connection. The plate interacts with a recess on the corresponding other element, into which recess the plate is inserted in a precisely fitting manner, with the result that moment and force transfer is possible by contact pressure via the end faces of the recess and of the plate. In this way, corner connections of this type can be configured without complex connecting devices and with less material outlay.

Title: Anti-dazzle device in motor vehicles
Inventor: RAIDA JOACHIM
IPC: B60J3/02
Filed: 1984-05-05
Abstract: The invention relates to an anti-dazzle device in motor vehicles, by means of which one or more light filter panels can be moved into the field of vision of the driver or front seat passenger. The invention is based on the object of providing an additional device which is simple in design and by means of which the hazardous dazzling of the driver of a motor vehicle is effectively prevented both during the day, as a result of the sun being low in the sky, and also at night, as a result of the headlights of oncoming traffic. This object is achieved according to the invention in that the light filter panel corresponds in width and height approximately to the dimensions of the sun visor which is installed in series-produced vehicles and is mounted inside as an integral component or as a retrofitted component on the sun visor. The anti-dazzle device according to the invention dispenses with the need to wear sunglasses, which are in any case usually not being worn when dazzling occurs. Therefore, it significantly increases general safety in traffic. The conventional inadequate sun visors fulfilled their function only imperfectly and are by far inferior to the anti-dazzle device according to the invention since for the first time hazardous obstacles to visibility as a result of dazzling can be avoided in any traffic situation.
Patent DE-3422602-A1 (DE)
Title: Method for determining material defects in a sample
Inventor: KROENING MICHAEL DIPL PHYS DR
IPC: G01N29/06
Filed: 1984-06-18
Abstract: In order to determine material defects in a sample by means of ultrasonic holography, ultrasonic test heads are placed on a surface of the sample as transmitters for ultrasonic waves, so that they irradiate the sample at specific angles relative thereto. The signals picked up by the ultrasonic test heads as receivers, which emanate from the material defects as a reflection of the ultrasonic waves, are fed to a computer for storage, in order that holographic evaluation can be performed. In the invention, two or more test heads having a sound bundle divergence of 20 DEG  or less with different angles of sound incidence are operated as transmitters and receivers. Their reflection signals are combined in a phase-matched fashion in the computer to produce a hologram having a synthetic aperture which is substantially larger than that of the individual test head. <IMAGE>

Patent DE-3428381-A1 (DE)
Title: Method and worm extruder for compacting and dewatering solid material
IPC: B30B9/12
Filed: 1984-08-01
Abstract: This kind of worm extruder is used to process solid material which is removed by a rake cleaning installation from the inlet side of a rake. The mostly wet solid material is fed to a feeding aperture (7) of a worm casing (2), where it is taken up by the worm (1) and transported towards an outlet aperture (11), while at the same time being pressed and dewatered. A dewatering zone (14) with an annular dewatering chamber (16) adjoins the feeding aperture (7). The worm (2) extends only approximately half way along the dewatering zone (14), leaving a space which is free and without constriction between the end of the worm and the outlet aperture (11), in which space the solid material is further pressed and dewatered. The outgoing liquid is guided through dewatering bores (15) into an annular dewatering chamber (16), from whence it is guided away via an opening (18), while the dewatered and pressed solid material is removed via a guiding pipe (17). Accumulations of the heterogeneous solid material are reliably avoided by forming a constriction-free space upstream of the outlet aperture (11), while at the same time achieving a good dewatering performance. <IMAGE>
Patent DE-3428900-A1 (DE)
Title: Curtain rail
IPC: A47H1/06
Filed: 1984-08-04
Abstract: The invention relates to a profiled strip, in particular a curtain rail or curtain rod. The rail body is of parallelogram-type or trapezoidal construction. A correspondingly inclined narrow or broad side of a further rail body can be attached thereto such that parallelogram-type and trapezoidal curtain rails can be combined with one another. In this case, as is also the case with individual rails, the front edges are bevelled or constructed as front edges with a shadow joint effect. The parallelogram-type or trapezoidal curtain rails can be constructed, for example, with one track on the underside and two tracks on the rear, it being possible for both sides to be used as rail tracks and/or mounting tracks. This two-sided utilisation also constitutes an innovation for rectangular curtain rails. If a single-track and a double-track curtain rail are now joined together, a triple-track curtain rail is obtained. As a result, the essential object of the invention becomes clear. A profile, which can be used on both sides, can be joined together and combined, saves considerable tool and storage costs. Instead of the usual four curtain rail profiles for a complete system, according to the invention only one or two different profiles are required.
