Patent DE-3225295-A1 (DE)
Title: Method for decelerating an electric motor drive into a destination position
Inventor: WEHKING HANS
IPC: G05B19/416
Filed: 1982-07-07
Abstract: The deceleration of an electric motor drive into a destination position is controlled in accordance with a deceleration characteristic in such a manner that the clock signals, which in each case correspond to equal movement distances, of a clock transmitter which is coupled to the drive are compared with the output of a time transmitter. The time transmitter is operated using stored time values which correspond to the time interval of the clock signals when using the deceleration characteristic. In this case, the operating sequence of the time transmitter before the occurrence of the clock transmitter signal causes the drive to accelerate, while the occurrence of a clock transmitter initiates braking of the drive.

Title: Pillow or bolster
Inventor: HAEUSSLING WALTER-HEINZ
IPC: A47G9/10
Filed: 1982-08-03
Abstract: A known so-called three-chamber cushion as a pillow comprises three approximately uniform, transversely extending regions having different packing density and hence different resilience for the shoulder, neck and head regions of the individual using it. As an improvement and refinement of this embodiment it is proposed that the shoulder region (1) be assigned roughly the lower half of the pillow, the head region (2) be assigned roughly two thirds of the upper half and the neck region (3) having the larger packing density be assigned the remaining sixth of the overall height (H) of the pillow. <IMAGE>

Title: Insulating board having ventilation layers
Inventor: WIEHOFSKY FRITZ
IPC: E04F13/04
Filed: 1982-08-06
Abstract: The invention describes an insulating board having an intermediate ventilation layer of porous material. Since plastered exterior wall insulating layers form a temperature barrier, temperatures passing through the plaster are not passed through the masonry but are reflected onto the plaster. This causes plaster stresses and cracks. The ventilation layer according to the invention absorbs temperature entering the outer insulating layer and passes it on. This eliminates the stresses and cracks in the exterior plaster. In addition, due to the ventilation layer facing the exterior wall, the insulating board according to the invention acts in a dissipating manner for the emerging vapour pressure from inside. Formations of condensate between masonry and insulating board are avoided.

Filed: 1982-11-18
Abstract: The invention relates to a lavatory or bath shower cup, which is fastened upright on a wall or the like in such a way that it can be swivelled or swung down by a mechanism attached on one side and, by means of a cable line, which is connected on the opposite side of the mechanism or a swivelling device to the lavatory or bath shower cup, is swivelled down over the existing installation, lavatory or bath, via deflection rollers, by a hand-operated crank device or winch or an electric-motor gear unit and is consequently converted into a shower device and, conversely, after swivelling up, in each case reverts it to the device it was before. The lavatory or bath shower cup may also be fitted on a mobile frame and made to run over the existing installation. This makes it possible to provide a shower device in small rooms, without further installations such as a fresh water supply line or used water outflow and without additional space.
Patent DE-3301061-A1 (DE)
Title: Bending machine
Inventor: PAULUS KARL
IPC: B21D7/14
Filed: 1983-01-14
Abstract: Bending machine for bending bar-shaped components with a central section which remains straight, in which the component is clamped in a rotatingly drivable clamping head. For the purpose of working the component from both ends and for supporting it, bending heads are arranged on both sides of the clamping head and, like the clamping head, these bending heads are held in a raised position relative to a machine bed guideway in order to be able to swivel bent sections of the components in the free space created. To alter the relative distances between the clamping head and the bending heads, the clamping head can be fixed and the cantilever-like raised portions of the bending heads displaceable or one bending head can be held in a fixed location and the cantilever-like raised portions of one bending head and of the clamping head can be displaceable. For radial access or removal of the component from the clamping head, the clamping means, the pivot mounting and the driving element have radial cut-outs. By bending the component from both ends, the length of the finished component can be at least doubled relative to that of a component bent in the conventional manner from one end, measured by the overall length of the workpiece components which can be cantilevered. This and the radial removability of the component open up new application possibilities.
Patent DE-3302797-A1 (DE)
Title: Tube reactor
Inventor: BORN GERHARD ING GRAD
IPC: B01J19/00
Filed: 1983-01-28
Abstract: A tube reactor for treating liquids with gas, for example for neutralising alkaline liquids, which reactor contains a plurality of substantially straight, preferably vertically arranged reactor tubes, which are connected to one another via lateral transfer pieces to give an arrangement in rows, can be substantially improved in its efficiency and its degree of utilisation of the treatment gas by fitting a mixing nozzle, carrying a flow of the liquid/gas mixture, in each case in the inlet region at the front end of at least those reactor tubes to the exit of which a transfer piece is connected. These mixing nozzles can be designed as a continuous, for example conical narrowing of the internal pipe cross-section and subsequent sudden widening to the full internal tube cross-section. The improved tube reactor is particularly suitable for the neutralisation of alkali-contaminated treatment water from cleaning machines, in particular bottle-cleaning machines. A special possible use results for the alkali-contaminated treatment water which has been taken from the warm-water treatment zone of a bottle-cleaning machine and which is to be recycled after neutralisation into the bottle-cleaning machine, in which case the neutralising gas can be a CO2/air mixture discharged from a bottle-filling machine.

Title: Device for gluing on the fly-leaf
Inventor: KRATZSCH ACHIM
IPC: B42C9/02
Filed: 1983-02-12
Abstract: The invention relates to a device for gluing on the fly-leaf in bookbinding machines, in particular in folding and adhesive binding machines, with which device, after the backs of the inner books have been glued, the fly-leaf sheets which are set back relative to the latter are glued to the inner book. The object to be achieved envisages providing a device for gluing on the fly-leaf, which device can be incorporated in the structure of a folding and adhesive binding machine and allows fixed bonding of the fly-leaves with minimum application of glue. According to the invention, by means of glue applying elements which can be constructed, for example, as disc-shaped gluing wheels, two additional lines of glue are applied to the glued side of the fold strip, with which the space (y) between the back of the inner book and the lower edge of the set-back fly-leaf is filled. In order to ensure in-register application of the lines of glue on the fold strip, the gluing wheels are arranged so as to be adjustable in accordance with the thickness of the inner book and the thickness of the application of glue to the end sides of the gluing wheels can be regulated by doctor blades. Arranged on the unglued side of the fold strip are a swivellable deflection roller and marking elements for checking the correctly positioned application of the lines of glue.
Patent DE-3307911-A1 (DE)
Title: Process and equipment for preparing dispersions
Inventor: KLINKSIEK BERND DIPL ING
IPC: B01F9/00
Filed: 1983-03-05
Abstract: The process is based on the liquid to be dispersed being pressed through a jet nozzle (4 or 5). The necessary upstream pressure is not generated externally by a pump but results from the jet nozzle (4 or 5) and the liquid to be dispersed being set into rotary motion relative to one another. In equipment suitable for carrying out this process, one or more jet nozzles (4, 5) are arranged with their axes parallel inside a pump chamber (2) on a rotating circular disc (3) which divides the pump chamber (2) into two halves (a and b). In this design, the jet nozzles (4 or 5) rotate inside the liquid to be dispersed. As a result, a back pressure is generated at the nozzles (4, 5) which causes the liquid to be dispersed to flow through the nozzles (4, 5). Alternatively, the equipment can also be designed in such a way that one or more jet nozzles (4 or 5) are in a fixed arrangement inside a centrifuge (15) filled with the liquid and are connected to an outflow pipe (19) for the dispersion. In this design, the back pressure responsible for the delivery action is generated at the nozzle (4) by the rotation of the liquid. <IMAGE>

Title: Stationary telephone station with a receptacle, mounted detachably on a base plate, for the operating devices
Inventor: LUDWIG MAX
IPC: H04M17/02
Filed: 1983-05-30
Abstract: Telephone station (1) consisting of a base plate (2) and a pot-shaped receptacle (3), detachably connected thereto, for the operating devices. The base plate (2) and the receptacle (3) are latched to one another by a bayonnet closure (10, 11) and secured by a lock in the latched position. An element connecting the two parts (2, 3) is to be created by means of which a rotating and swivelling movement of the two parts (2, 3) with respect to one another is possible. For this purpose, a rotating hinge (16) is used. The rotating hinge (16) contains an arc-shaped arm (17) of circular cross-section, which is connected at its free ends to angle-shaped webs (18) which engage with pins (20) provided at their free ends (19) in holes (21) of angles (22) mounted on the base plate (2). On the arc-shaped arm (17), a U-shaped holding bow (23) is supported rotatably and displaceably in the axial direction of the arm, which is connected in its base area (24) to the pot-shaped receptacle (3). Due to such a design of the rotating hinge (16), for example, the receptacle can first be guided into and out of the latched position by rotation due to the holding bow (23) displaceably supported on the arm (17). After the latching has been opened, for example, the receptacle (3) can be swivelled for maintenance purposes. <IMAGE>

Title: Circular hand saw with swivelling bottom plate
Inventor: FUCHS MICHAEL ING GRAD
IPC: B27B5/29
Filed: 1983-09-20
Abstract: In a circular hand saw with a bottom plate which can be swivelled by means of a bell crank lever pivotably mounted on an eye of the bottom plate and accommodating the pivot of the counter-bearing, the mechanical connection between the saw casing and the bell crank lever is to be improved in such a way that the bottom plate can be exchanged more rapidly than before and that the circular hand saw can be converted without problems to a saw for blind joints. According to the invention, this is achieved by virtue of the fact that the pivot of the saw casing is formed by a hinge pin attached fixedly to the bell crank lever and that the saw casing is provided with a swivel bearing which can be expanded counter to a restoring force for the purpose of inserting and removing the hinge pin of the bell crank lever. <IMAGE>

Title: Mechanism to prevent over-revving of the turbine rotor of a gas turbine engine in the event of a broken shaft
Inventor: ROBERTS DEREK AUBREY
IPC: F01D21/04
Filed: 1983-10-06
Abstract: The invention relates to a mechanism to prevent over-revving of the turbine rotor of a gas turbine engine in the event of a fracture of the shaft connecting the turbine rotor to a compressor rotor. The segments of a guide-wheel arranged downstream of a turbine rotor stage are mounted axially tiltable on their outer circumference and fixed on their inner circumference such that they can be unlocked. If, in the event of a broken shaft, the turbine rotor displaced axially backwards encounters the inner mounting structure of the guide wheel segments, the latter are unlocked on their inner circumference and can tip out axially into the orbit of the turbine rotor blades, as a result of which the rotor blades are destroyed and the turbine rotor is braked.

Title: Method and circuit arrangement for producing operating voltage in a subscriber device which is flowed remotely via a telecommunications line
Inventor: ZSCHAECK THOMAS DIPL ING
IPC: H04M19/08
Filed: 1983-10-14
Abstract: Remotely-flowed subscriber devices are intended to have a DC input impedance which is as low as possible. If a control circuit having a voltage-controlled voltage source is provided in the subscriber device, then the operating point of the voltage-controlled voltage source can be defined such that, in the event of different loop DC currents and different amplitudes of the transmission and reception signals, the drive range of a transistor which is arranged in the voltage-control voltage source is not exceeded. In order to achieve an operating voltage which is as high as possible with an adequate drive range, the control circuit changes the voltage drop on the voltage-controlled voltage source as a function of the loop DC current flowing instantaneously on the telecommunications line.
