Title: Strand guiding system for a continuous casting plant for the continuous casting of metal melts
Inventor: STULIK JIRI DIPL ING
IPC: B22D11/128
Filed: 1983-05-06
Abstract: In a system with rollers for supporting and guiding, and with force-transmitting rollers for deflecting into the horizontal direction the strand which leaves the mould downwards and which still has a liquid core, the force-transmitting rollers (bending and/or straightening rollers) are respectively arranged along a transition curve (f(x,y)) with a changing curvature (1/R), which transition curve extends between two strand guiding sections with different curvatures. In order to reduce the load on the rollers of a strand guiding section adjoining a transition curve (f(x,y)), and to reduce the extraction forces for the strand, the curvature (1/R) of the transition curve (f(x,y)) is greater in its end region (15) than the curvature (1/RE) of the strand guiding section following the transition curve (f(x,y)). <IMAGE>

Title: Signalling device for hot plates, especially glass-ceramic hot plates
Inventor: TRAUNSPURGER GUENTHER ING GRAD
IPC: H01H37/04
Filed: 1983-05-10
Abstract: In glass-ceramic hot plates it is known to provide a signalling lamp at an easily visible point, which signalling lamp indicates the heating of the hot plate above a specific touching temperature, even once the hot plate has been switched off (residual heat indication). To this end, a temperature-dependent switch for controlling the signalling device is coupled in a thermally close manner to the hot plate as well as to special heat-storage bodies. According to the invention, the construction and assembly of the signal control device are improved in that all the components, such as the PTC thermistor heating, the heat-storage body, the contact plate and the like, can be stacked in a housing receptacle like a trough and can be clamped to one another by means of a clamping bracket. <IMAGE>

Title: Antifreeze pump for pneumatic brake systems, especially of motor vehicles
Inventor: RUESS LEOPOLD
IPC: B60T17/00
Filed: 1983-05-11
Abstract: In the case of an antifreeze pump for pneumatic brake systems, especially for motor vehicles, a piston (13) which can be displaced by the pressure of compressed air, is carried in a housing (3), which piston, according to its stroke, pumps antifreeze from a tank (1) into a compressed air feed line. The stroke of the piston, which determines the amount of antifreeze in such a way that a long stroke delivers a larger amount of antifreeze, can be determined by a stop (31). The stop acts by means of stop surfaces (33, 35, 37) having a variable position in relation to the facing end part (37) of the piston (13); the stop can be moved into different positions by means of a hand wheel (5) in such a way that the stop surfaces reach the stop position at different intervals from the end part (39) of the piston. The stop (31) can be shifted into one of its stop positions by means of actuating elements in the form of leaf springs (41, 43, 45) mounted in the hand wheel according to the rotary position of the hand wheel, and is accordingly preselectable.

Title: Feeding and sorting device for pellets, preferably gassing pellets
Inventor: SCHLINZIG ECKHART DR ING
IPC: B07B13/04
Filed: 1983-05-16
Abstract: The invention relates to a feeding and sorting device for pellets, preferably gassing pellets for combating pests in grain silos, in which a vibrator pot is located with its outlet in front of a magazine with a chute. The aim of the invention is to increase operational reliability. When gassing pellets are used, the previously determined concentration of gas in the grain silo is to be maintained. The object of the invention is to improve the known feeding devices, by only feeding whole pellets to the magazine with a chute, while breaking and abrading the pellets separately. According to the invention, an ejector with an opening is attached to the outlet of the conveyor attachment. Its sliding surface is adapted to the side walls of the upper part of the magazine with a chute and is located under the magazine at some distance from it. Another advantageous feature of the invention is that the ejector is to be designed as a frame in which two slide rods are placed at a distance which is smaller than the diameter of the pellets. The slide rods can be centrally or asymmetrically attached in the ejector frame. <IMAGE>

Title: Circuit arrangement for reducing the contact resistance in measuring electronic components
Inventor: MERKLIN KLAUS ING GRAD
IPC: G01R27/20
Filed: 1983-06-22
Abstract: The circuit arrangement contains a measuring device (1) and a pair of two-part measuring contacts (k1, k2) connected thereto. These measuring contacts consist of a sensor line (2) and (2') and a measurement current line (3) and (3'). Between the sensor line and measurement current line, a pulse transformer (i1, i2) and a capacitor (c1, c2) are in each case arranged in such a manner that the first terminal of the secondary winding (w2) of pulse transformer (i1) is connected to the sensor line (2) and the second terminal is connected via the capacitor (c1) to the measurement current line (3). This correspondingly applies to the sensor line (2') and the measurement current line (3'). The first terminals of the primary winding of the two pulse transformers (i1, i2) are connected to one another and are connected to the zero point of the circuit via the electronic switch (es) whilst the second terminals of the primary windings are also connected to one another and to the constant-current source (kq) and are connected to the zero point of the circuit via the third capacitor (c3). The contact resistance is reduced by partial and temporary welding of the contact areas of the sensor and measurement current lines to the component terminals. <IMAGE>

Title: Device for sucking up liquids
Inventor: JOHANSSON SIGVARD ANSELM
IPC: F04F5/48
Filed: 1983-09-16
Abstract: The invention relates to a device for sucking up a liquid and for collecting said liquid in an oil barrel or a similar container, which, firstly, has at least two sealable openings (3, 4), to which a jet suction pump (5) and a suction tube are detachably connected. Because it is difficult to detect when the container is beginning to get full, an operationally reliable float valve device (11) must be fitted in order to close the suction device automatically. This float valve device is incorporated in a suction pipe connection (10) which is connected to the pump (5) and projects into the container (1). Accordingly, the float valve device (11) is protected by the pipe connection (10) and therefore cannot be damaged by careless operation of the pump (5) if the pump happens to be unconnected to a container (1). <IMAGE>

Title: Film welding device, especially for domestic purposes
Inventor: BARTH ANTON
IPC: B65B31/06
Filed: 1983-09-28
Abstract: The invention relates to a film welding device, especially for domestic purposes, having a pump, from which at least one air channel extends, which air channel encloses a connection nozzle insertable between two films, for example of a film bag. The object is to be achieved of substantially reducing the danger of sucking in filling product and especially of reducing contamination of the air channels and the pump and of improving the cleanability. To achieve this object, it is proposed to dispose a liquid trap (36, 62, 78, 80; 644; 740) in the air channel (22, 12; 640; 730, 732), which allows air to pass easily but liquid to pass only greatly retarded, if at all. <IMAGE>

Title: Safety-belt reeling mechanism
Inventor: FOEHL ARTUR ING GRAD
IPC: B60R22/46
Filed: 1983-10-20
Abstract: When a beltband-sensitive mass disc is present on the control disc of a ratchet blocking device, there is the risk that, as a result of the extremely high angular acceleration during the tightening operation, the forces emanating from the mass disc will destroy the following parts of the ratchet blocking mechanism. To prevent this, a coupling element is provided between the control disc and mass disc, in such a way that, when a predetermined tightening acceleration is exceeded, the mass disc can be rotated relative to the control disc, thereby overcoming the coupling force. <IMAGE>

Title: Pneumatically actuated, mechanically applied full-lining disc brake, in particular for motor vehicles
Inventor: KLAUE HERMANN DR ING
IPC: F16D55/14
Filed: 1983-12-07
Abstract: The invention relates to a further development of the mechanically actuated full-lining disc brake with an application device which comprises concentric rings with oblique tracks rising in the circumferential direction and rolling elements for expansion. It is proposed to support on a two-part brake anchor plate an actuating-cylinder ring which is connected non-positively to the ring of the application device and which, together with a part of the brake anchor plate, has in the same radial area ribs which form encapsulation spaces of adjustable volume into which compressed air is passed to actuate or release the brake. The elimination of the actuating shaft and of the slack adjuster and actuating cylinder arranged outside the brake results in a saving in expenditure and weight and a reduction in the installation space. <IMAGE>
Patent DE-3402119-A1 (DE)
Title: Pressure regulator
Inventor: JUHASZ JOSEF DIPL ING
IPC: G05D16/20
Filed: 1984-01-23
Abstract: The pressure regulator has a housing (10) in which a coil (12) is arranged which interacts with a magnetic armature (31) in the form of a disc. The latter is seated on a shaft (25), which is supported in the housing coaxially with respect to the coil (12) and acts on a control slide (16) which is arranged in a valve housing (14). Fitted to the external circumference of the magnetic armature (31) is a layer (33) consisting of an electrically highly conductive material, especially copper. The outer circumference, and with it the layer (33), are incorporated into the magnetic circuit such that the magnetic flux flows through them. The layer is preferably constructed as a copper ring and is located at the point of high magnetic flux density. In this way, in the case of a pressure regulator having only very low permissible mechanical friction, simple damping is achieved which arises as a result of a voltage being induced in the layer (33), which voltage causes a current which counteracts the changing electrical field. <IMAGE>

Title: Dental treatment chair having a head wedge fastened on a belt
Inventor: BURCKHARDT HOLGER
IPC: A61G15/12
Filed: 1984-04-12
Abstract: In order to support the patient's head in a manner appropriate for the treatment, a head wedge whose height is adjustable by means of a belt is frequently used in dental treatment chairs. In a known arrangement, the belt is provided with a rolling-up mechanism housed in a head rest part for the purpose of height ajdustment. In order to avoid the precision parts necessary for this a solution is proposed in which the head wedge is connected to the belt so as to be displaceable along the belt.

Patent DE-3436180-A1 (DE)
Title: Pump for liquids and gases
Inventor: DEYEN HEINZ
IPC: F04C2/344
Filed: 1984-10-03
Abstract: This is a pump type which can be designated as a disc-plate pump. This is because the support element, like the conveying plate moving therein, is disc-shaped. This pump can be operated as a liquid pump and an air pump. Owing to the special construction of the disc-plate pump there are only small volume losses due to fitted conveying elements, because these elements take up little room in the disc-plate pump. Distinctive characteristics of the pump are   the disc-shaped design of the conveying elements and of the pump casing, the positioning of the conveying elements away from the centre, and the compensation of the diameter differences resulting therefrom by inserting springs which bridge these differences. The pump is self-priming and shows virtually no drop in performance against a high back pressure. Thus a pump having the dimensions 140 . 100 has a delivery rate of as much as 220 l per minute at 520 rpm. The pump can be operated while turning in either direction.
Patent DE-3436441-A1 (DE)

IPC: H04L12/26
Filed: 1984-10-04
Abstract: In a transmission network having a tree structure in which data is forwarded from the tree branches toward the trunk at periodic intervals, the data which is transmitted between the several network levels is transmitted in data blocks each having a status field and a data field, the status field identifying the status of stations at a lower level in the network. The information in the status field is reduced by deleting data corresponding to a predetermined status information content corresponding to the most probable configuration of such data. The remaining status data is divided into sub-sets and transmitted with an individual sub-address for each sub-set, and a control signal identifying the number of sub-sets which are transmitted, and an address identifying the sending station.

Title: Vertical cutting machine for foams
Inventor: BURCHARDT ROLF
IPC: B26F1/38
Filed: 1984-12-07
Abstract: A vertical cutting machine for foams having a substantially vertically aligned cutting element and a horizontal support surface (1) for the material to be cut (6), the cutting element extending downwards through the support surface (1) and being movable transversely through the support surface (1) along a straight-line slit (2), is to be so developed that the hitherto complex and person-specific manual work can be largely eliminated. The design prerequisites for an automatic cutting method in which the required movement operations can now be controlled as far as possible numerically and therefore rapidly and with constant accuracy are provided in that the support surface (1) on both sides of the slit (2) is formed by drivable elements which transport the material to be cut (6) selectably to the cutting element or away therefrom transversely to the direction of movement of the cutting element itself. The drivable elements can be in particular rollers or endless belts (1a). The cutting element can be pivotable in two planes in the region of the slit (2) (see angles  alpha  and  beta ). The proposed design principles can also be used for fully automatic cutting of other materials such as plastics of a different kind. <IMAGE>

Title: Lockable plug device, especially having a screw lock
Inventor: STURGES JAMES R
IPC: H01R13/633
Filed: 1985-01-04
Abstract: In order to secure the plug connection, the plug device (10) has mutually opposite contact-pressure surfaces (for example 170 and 24) of different flexibility with projections (26) and recesses (25) which, for example once the plug parts (11 and 12) have been plugged together, are engaged with one another, under pressure, by the means for securing the plug connection. In the event of the plug being secured by means of a cap nut (19), the contact-pressure surfaces are preferably of annular construction and, for example, the projections (26) of the one contact-pressure surface (170) are arranged distributed uniformly at the same angular interval, so that engagement points are produced at different rotation angles. The rotation force which has to be applied to rotate the cap nut (19) is in this case greater in each engagement position than outside said positions and, when the cap nut (19) is tightened, is sufficiently large to prevent the plug connection becoming detached by vibration.

Title: Process for treating industrial dirty water
Inventor: BUNN GUENTER
IPC: C02F1/28
Filed: 1985-01-10
Abstract: The present invention is oriented to a process for treating industrial dirty water and the like. The prior art here employs relatively complicated large-scale plants which are in no way suitable for medium-scale enterprises. The present invention is therefore based on the object of creating a simple and rapidly effective process which ensures the separating out of impurities, such as heavy metals, grease, organic substances, dye residues etc., without as a result the water treatment plant itself becoming excessively complex. This object is achieved according to the invention by pumping the dirty water into a first tank, then adding a predetermined amount of flocculating agent and precipitant and/or antifoam agent and stirring, then finally removing the dirty water from the first tank into an adjacent second tank by suction, namely via at least two filters which are connected in series having different pore size, so that at the end of the process, possibly after a sedimentation settling phase which is still to be carried out, the purified water can be pumped off from the second tank.
