Title: Trigger-grip trap, especially musk-rat trap
Inventor: LEPRICH DIRK
IPC: A01M23/24
Filed: 1986-12-11
Abstract: The trigger-grip trap is used to combat musk rats. The field of use is terrain which is difficult of access. The minimal weight necessary for this is achieved by a small input of materials and individual parts. Environmental awareness, which is important for us, requires traps which reliably catch the musk rat and exclude the catching of birds. The trap described here also meets this requirement in that a particularly complex, simple and unique release mechanism has been developed which, when the bait is taken, is only released when the traction movement to release the food takes place in the same way as with the musk rat or similar. Since traps of this generic type cause metal frames to move together for gripping purposes, there are also risks for the users. These, however, are prevented, since the traps, when set, are immediately made safe automatically. The handling of elaborate mechanisms, necessary for setting other traps, is superfluous. This trap is so designed that it is suitable only for catching by means of bait. All traps which are suitable for catching animals passing through are not safe for birds, since every animal passing through can cause a releasing contact!

Title: Speed regulating device
Inventor: SCHOTTEN HENNO DIPL ING
IPC: D06F37/30
Filed: 1987-01-16
Abstract: A speed regulating device for the drive of a washing machine drum has an integrated regulating circuit (2) having a speed desired value input (4) and a speed actual value (5). In order, in the case of spins of short duration (varying speed spinning), to cause the drum to just reach the desired speed and then immediately to switch off its drive, an additional control circuit (6) is connected to the desired value input (4) and the actual value (5) of the regulating circuit (2). The control circuit (6) is activated by a contact (K3) of the programme switch mechanism. The control circuit (6) connects a switch-on signal to the desired value input (4) for the spins of short duration. It connects a switch-off signal to the desired value input (4) if the actual speed is equal to the desired speed of the spins of short duration. <IMAGE>

Title: Arrangement for controlling a building heating or cooling system
Inventor: BREITENSTEIN BERND DIPL ING
IPC: F24D19/10
Filed: 1987-02-02
Abstract: It is a known method to determine the duration of heating up rooms from the difference  DELTA T between the desired room temperature and the actual room temperature at the start of heating, and to begin heating at a time (t2) that is earlier by the calculated duration of heating up (tr) than the time (t4) at which the desired room temperature (Ts) is supposed to be reached. An arrangement is given with which the duration of heating up (tr) is calculated with great accuracy, with small computing and memory requirements. The equation tr = exp (A. DELTA T+B) is assumed to apply to the duration of heating up. The actual duration of heating up (tm) is measured. The parameters A and B are determined adaptively by a recursive method from the deviations between the measured and calculated duration of heating up. The invention is used in heating systems. <IMAGE>

Title: Process for concentrating a waste solution from flue gas purification
Inventor: SCHMITZ REINER DIPL ING
IPC: C02F1/04
Filed: 1987-02-05
Abstract: The invention relates to a process for concentrating, by evaporation, a waste solution from the purification of flue gases, in particular brown coal flue gases, which solution contains alkaline metal chlorides, alkaline earth metal chlorides, alkali metal sulphates, and alkaline earth metal sulphates as well as sulphur compounds and nitrogen compounds. In order to specify as simple a process as possible for concentrating waste solutions of this type by which process the disadvantages existing hitherto are avoided as far as possible, it is proposed that the solution, before or at the beginning of the evaporation, is heated at a pH below 7, which is established if necessary by addition of acid, and kept at an elevated temperature, in particular boiling temperature, until the pH has markedly decreased (reaction stage), that undissolved solids are separated off from the mother solution and that the solution, at the latest in the final phase of the evaporation, is neutralised or elevated to an alkaline pH. <IMAGE>

Title: Rotational-movement locking mechanism
Inventor: WINZINGER FRANZ
IPC: G04B11/00
Filed: 1987-02-11
Abstract: Known rotational-movement locking mechanisms, the direction of engagement of which runs parallel to the axis of rotation, consist, on the one hand, of a locking plate rotatable about the axis of rotation and of a locking wheel connected fixedly in terms of rotation relative to the axis of rotation. On the other hand, rotational-movement locking mechanisms of this type also have catch elements which, under the action of a spring force, retain the locking wheel and locking plate in different catch positions relative to one another. At the same time, the spring force is exerted by a spring element which is supported on part of the housing receiving the rotational-movement locking mechanism. The locking wheel according to the invention consists of a hub, of a rim and of spokes extending between them, the locking plate being secured axially on the hub. The rotational-movement locking mechanism according to the invention thus now consists of only two parts which can be assembled in a simple way. <IMAGE>

Title: Process for controlling the contact pressure between a contact roller and a roll being wound which is driven by the latter
Inventor: FEISTKORN WERNER DIPL ING DR
IPC: B65H18/26
Filed: 1987-10-29
Abstract: For controlling the contact pressure between a contact roller, which is mounted in the machine frame and is provided with a drive, and a roll being wound, formed by winding a film web on a winding shaft or a core, the roll being wound is mounted so as to be rotatable between two arms which are parallel to one another and mounted so as to be pivotable in the machine frame. To drive it and wind it with essentially uniform web tension, the roll being wound is pressed against the contact roller. The contact pressure is adjusted by means of a pivot drive as actuating element, which is controlled by a controller which forms the actuating signals from input variables corresponding to the respective weight of the roll being wound and to the angle of inclination of the support arms with respect to the vertical, and by comparison with a set point value which corresponds to a desired contact pressure. To allow the force component resulting from the weight force of the roll being wound and acting in the direction of the contact roller to be determined more accurately, the anglular velocity or rotational speed of the winding shaft or roll being wound and the velocity of the web to be wound are measured and the measurement values are input into the controller as parameters for determining the angle of inclination.

Title: Apparatus for placing in and removing from storage for silos
Inventor: STROECKER GUENTER DIPL ING
IPC: B65G65/06
Filed: 1987-12-22
Abstract: In the silo (1) according to the invention, the removal of the bulk material from storage takes place at the silo bottom (24) via at least one discharge channel (25) constructed here, use being made of a discharge unit (29) which comprises, for example, a clearing wheel, a clearing plough or another type of discharge conveyor. The operation of removal from storage is supported by means of a clearing and distributing device (9), in particular a clearing beam (12), which can be swivelled about the silo axis and can be raised and lowered in the silo. The conveying direction of the clearing and distributing device is reversible so that the latter can either distribute the bulk material over the silo cross-section during placing in storage or discharge the bulk material into the funnel (31), falling as a result of the discharge at the bottom, during removal from storage. The clearing and distributing device is mounted on a lifting frame (5) which is guided on the silo wall in a rotationally positive manner. The feeding of the bulk material to be placed in storage takes place centrally from above via a telescopic tube (3) for placing in storage. <IMAGE>

Title: Piston-connecting rod joining in internal combustion engines
Inventor: BAUDER ARMIN
IPC: F16J1/16
Filed: 1988-04-28
Abstract: In a piston-connecting rod joining in internal combustion engines, in which the connecting rod is axially guided by its big end bearing between the crank webs, it is proposed, in order to reduce the distance between the bearing points 7 of the piston pin in the piston pin bosses 5 of the piston 6, to bevel the side faces of the small end bearing 3 in its area 13 lying above the piston pin axis 10, whilst the adjoining area 8 aligns with the corresponding side face of the large end bearing, in order to permit simultaneous machining of the said side face and a secure seating for siting the piston pin bore 4. The end faces 14, 15 of the piston pin bosses 5 lying opposite the small end bearing 3 run essentially parallel to the end faces of the small end bearing 3, whilst the end faces of the bearing bushes 7 in the end bearings 5 run perpendicular to the piston pin axis 10. In order to permit the necessary axial play, counterbores 19 surrounding the piston pin bore 4 are provided in the side faces of the small end bearing 3, into which counterbores the end faces 16 of the bearing bushes 7 can immerse with a relative displacement between piston 6 and connecting rod 1. <IMAGE>

Title: Device for separating a solid/liquid mixture into its solid components and its liquid component
IPC: B30B9/12
Filed: 1988-05-17
Abstract: In the case of a device for separating a solid/liquid mixture into its solid components and its liquid component using a worm extruder, the free end of the shaft of the worm is situated in the conveying direction, is free of conveying plates, acts as a plunger and fits into a shoulder which takes the form of a cylinder press and adjoins the casing of the worm extruder. Furthermore, the worm is mounted so as to be axially displaceable and permits, in its end position situated in the direction of input into the worm extruder, passage through the casing and the cylindrical shoulder and in its other end position situated in the conveying direction, the worm projects with its end which is free of conveying plates, as a plunger into the cylindrical shoulder and blocks the passage through the casing and the cylindrical shoulder. The pre-dehydrated separated material which is situated in the cylindrical shoulder can be compacted in this process and conveyed out of the extruder.

Title: Refuse collection vehicle
Inventor: BEHLING HANS-JUERGEN
IPC: B65F3/02
Filed: 1988-06-29
Abstract: In refuse collection vehicles having a refuse charging system arranged behind the cab, an adjacent refuse compaction device and a refuse collection container arranged behind the latter, it has hitherto been possible to achieve sufficient compaction of the charged refuse within the refuse collection container, so that the refuse collection container is only inadequately utilised. According to the invention, a counter-pressure plate which is mounted on the lid of the refuse collection container to be radially pivotable and can be subject to the action of a compressive force is arranged in the region of action of the refuse compaction device, and forms a counter-pressure element for the charged refuse. As a result, it is possible to compact uniformly the refuse charged into the refuse collection container from the start of refuse charging until the refuse collection container is completely full and thus achieve increased utilisation or payload of the refuse collection vehicle.
Patent DE-3821990-A1 (DE)
Inventor: ONDERKA BERND
IPC: B21B37/52
Filed: 1988-06-30
Abstract: When rolling sections in universal stands of continuously operating section rolling mill trains, it has been found that changes in the speed ratios between the horizontal rolls and the vertical rolls lead to undesired material flow changes. As a result of the horizontal roll speed, the deformation in the section parts, the resulting transverse flow and the external forces at the roll gap, a certain speed is produced in the vertical rolls in proportion to the horizontal roll speed. Any change of the edge conditions of the rolling process leads to a change of the speed ratios between horizontal and vertical rolls. In order to eliminate these disadvantages, it is proposed to control the speed of the vertical rolls of the universal stands to influence optimally the horizontal roll speed and the vertical roll speed via a control device and to obtain a minimal pull between stands via a further control.

Patent DE-3831341-A1 (DE)
Title: Winding machine
Inventor: SCHIMINSKI HERBERT
IPC: B65H65/00
Filed: 1988-09-15
Abstract: In a winding machine for a continuously running thread, the thread is first guided to the traversing device via a head thread-guide. During the placing of the thread onto a new empty tube, the running thread is lifted out of the traversing device and is guided by two transfer thread-guides which guide the thread laterally outside the traversing stroke. An especially favourable position of the thread in relation to the catching slot made in the empty tube is achieved in that the head thread-guide is movable out of its position centrally above the winding device into the normal plane of the catching slot.
