Title: Junction connection
Inventor: GRIMM FRIEDRICH BJOERN DIPL IN
IPC: E04B1/19
Filed: 1986-03-29
Abstract: The invention relates to a junction connection for a junction/bar system having a junction comprising two clamping pieces which can be braced together with the aid of a centrically arranged screw and exhibit diametrical, annular cutouts which serve to receive the bar ends, which are to be introduced therein, and have concentrically formed and axially offset protrusions and depressions which can be connected in a frictionally locking manner to the protrusions and depressions of the bar ends.

Patent DE-3620505-A1 (DE)
Title: Infinitely variable mechanism
Inventor: SOEHN PAUL GERHARD DIPL ING
IPC: F16H37/08
Filed: 1986-06-19
Abstract: In order to create an infinitely variable mechanism which allows the transmission of high powers or torques, having a drivable wheel and a wheel driven by the latter, the wheels are designed as bodies of revolution of differential axial lengths. By means of an increase in their diameter with length in the axial direction in the manner of an exponential horn, it is possible to ensure that the same ratios of their radii are obtained over the entire area of contact between their generated surfaces, giving the same transmission ratios within the entire area of contact and avoiding slip caused by unequal transmission ratios. The transmissible torques can be increased here by positively engaging toothed systems, one of which is fixed, while the other wheel is provided with displaceable driver elements which yield when they strike a tooth of the mating wheel but are capable of accepting tangential forces caused by the toothing of the mating wheel and transmit them inflexibly. An effect of a similar kind can be achieved if a fixed toothing engages in an electromagnetically held layer of magnetisable fine granules.

Title: Gear-driven air compressor, designed as piston compressor, with overload coupling
Inventor: KUBIS HERIBERT DIPL ING
IPC: F16D43/202
Filed: 1986-07-05
Abstract: By means of this invention it is proposed to achieve a backlash-free contact of the components in question and emergency operation for an unlimited period after shutting off of the air compressor in the event of overload. This is achieved in that the driving gear is positively connected, free from backlash, by way of a spur toothing to an annular gear provided on the crankshaft of the air compressor by a preloaded spring element for transmission of the drive torque, the torque of the driving gear being transmitted to the crankshaft of the air compressor by the annular gear frictionally preloaded by way of the driving gear hub. The characteristic of the spring element is designed so that, after lifting off of the spur toothing as a result of overloading, the spur toothing is completely separated by reversal of the spring element, and after disengagement the driving gear rotates, slide-mounted by means of a retaining ring, guided by the spring element now free of preloading force.

Patent DE-3629804-A1 (DE)
Title: Process with the associated equipment for generating energy with the help of artificial energy plants
Inventor: REENTS HEINRICH PROF DR ING
IPC: F03D5/06
Filed: 1986-09-02
Abstract: The invention concerns a process with the associated equipment for utilising renewable sources of energy. The essence of the invention is that the energy-conversion systems are integrated into plant-like bodies; the wind energy component is converted into electrical energy with the help of the intermittent principle; and the subsystems convert solar energy, wind energy, and wave energy at sea, into electrical energy. In order to increase the efficiency of conversion, vibration-generating systems, i.e. oscillators, are also employed. The carriers of the energy conversion systems are designed to resemble stalks, flowers, branches or trees. They can be grouped into energy fields and energy forests. The availability of the overall system is increased substantially by the combination of different conversion processes to form one system. Since the systems are designed to resemble plants, and can be operated economically even in small units in the long term, consumer acceptance of this process is expected to be high. The process and its associated equipment can be applied analogously to utilising the renewable sources of energy at sea.

Patent DE-3643134-A1 (DE)
Title: Slicing machine for foodstuffs
Inventor: GILGE OTTO
IPC: B26D1/143
Filed: 1986-12-17
Abstract: It is proposed in particular, in the case of a device having a fixed guiding table and a crumb channel which extends between the said table and the knife that a supporting rib be arranged adjacent to the cutting region of the knife, the said rib having a supporting surface for the material to be cut which is situated in approximately the same plane as the guiding surface. This ensures on the one hand that the device is easy to clean and on the other hand ensures that the device supplies accurately cut products, in that the material is not torn, made to crumble or distorted so much during cutting. Furthermore, the supporting rib can serve as a guide for a displaceable table and extend, for example, between the table and the knife, which arrangement on the one hand reliably prevents a collision between the table and the knife and on the other hand permits the material to be supported directly adjacent to the cutting region. This results in improved cutting performance and a reduction in tolerance problems regarding guiding of the carriage and the knife with respect to one another. The supporting rib can be vertically modifiable for use both with a guiding table and with a carriage which can be placed on the latter. <IMAGE>

Title: Device for simultaneously measuring the transverse thickness profile and the strip width during hot rolling of flat sections
Inventor: FLORMANN PAUL ING GRAD
IPC: G01B15/02
Filed: 1987-03-05
Abstract: The invention relates to a device for simultaneously measuring the transverse thickness profile and the strip edge position during rolling of metal strips (flat sections) by using radioactive emitters (radiators) and a multiplicity of radiation receivers. In a known measuring device, emitters and receivers are arranged on a frame which reciprocates to and fro at right angles to the rolling direction. The strip is thus measured on many zig-zag lines, but relatively large regions cannot be covered by the measurement radiation. The object of the invention is to measure the strips precisely in the edge region, in particular, and simultaneously to measure the thickness and the width. According to the invention, one emitter is assigned cylindrical radiation receivers which are arranged one behind another in a plurality of rows and from whose circular area only a centre strip is faded in in each case. The strips participating in the measurement are assembled next to and behind one another in such a way that the metal strip is measured without gaps and the receivers of adjacent strips are as far as possible apart from one another in the rolling direction. <IMAGE>
