Patent DE-3107423-A1 (DE)
Title: Transportable concrete mixer
Inventor: NAHL KARLHEINZ VON
IPC: B28C5/42
Filed: 1981-02-27
Abstract: The invention relates to a transportable concrete mixer by means of which concrete or mortar are often transported, even alternately. Since, after concrete has been transported, residues may be left in the drum, a screen is fastened at the lower end of the discharge channel while mortar is being removed. This fastening is complicated and, in particular, not sufficiently stable. If a vibrator is placed onto the screen, the vibrations emanating therefrom also act on the discharge channel in an undamped manner, with the result that a considerable amount of noise arises. According to the invention, the screen is now largely adapted to the trough shape of the discharge channel and inserted into the discharge channel. This permits the screen to be fastened in a manner in which, if required, it is easy to release and nonetheless stable. Since, in this arrangement, flexible intermediate layers can be easily fitted, the amount of noise arising is also lower. <IMAGE>

Patent DE-3127033-A1 (DE)
Title: Method for the correction of an indicative value for the translational speed of a vehicle, the axles of which slide
Inventor: DZAMKO OLEG DIPL ING
IPC: B60T8/17
Filed: 1981-07-09
Abstract: A wheel slide prevention device is described for rail vehicles, the axles (10) of which are braked by way of jointly actuated brakes (21). Sliding processes of the axles are detected by way of axle pick-ups (11) and an analysing device (13). On each axle (10) a sliding process can be counteracted by brief releasing of the assigned brake (21). Controls (23) assigned to the brakes serve for this purpose. In the event of synchronous sliding of all axles (10) a generator unit (12) generates a probable speed signal. At the same time the brakes on the sliding axles (11) are briefly released. On one of the axles re-braking is delayed until rolling of the axle has been re-established. This can be detected in that the positive re-acceleration of the axle turns into negative braking acceleration caused by the braking of the vehicle. The speed of the axle (10) is determined at the instant of inversion. This value serves for correction of the speed value emitted by the generator unit (12) at the same instant. <IMAGE>

Patent DE-3138464-A1 (DE)
Title: Method for the digital demodulation of frequency-modulated signals
Inventor: KAMMEYER KARL-DIRK DR ING
IPC: H03B28/00
Filed: 1981-09-26
Abstract: The concept of a purely digital demodulator for frequency-modulated signals in the VHS band is specified. To filter the selected channel out of the incoming signal, non-recursive systems are used which have the advantage of linear phase. Phase-distortions of the frequency-modulated signals can thus be completely avoided. For the demodulation, the incoming signal is transformed into the baseband range. A special digital demodulation algorithm produces the audio-frequency information signal. In the consideration of the individual subsystems, implementation aspects are taken into consideration. The work is concluded with a number of simulation results. <IMAGE>

IPC: B63H25/38
Filed: 1981-10-09
Abstract: In order to facilitate the pivoting, to be carried out with a tiller, of the rudder blade of a watercraft rudder arrangement without impairing the stabilisation of the rudder blade in the lowered and raised position and without putting at risk the automatic release of the rudder blade in the event of running aground, provision is made according to the invention to provide abutments as a catch device on the rudder, which abutments are directed to the front and to the rear in the fork-shaped tiller and interact with a cross bolt connecting the fork arms. A guide link is preferably arranged between the cross bolt of the forked tiller and a hinge bolt mounted on the abutment of the rudder head. The guide link moves in each case into an extended top dead centre position when the rudder blade is lowered and raised.
Patent DE-3140384-A1 (DE)
Title: Push-on device for valve bags
Inventor: SWILLUS ALFRED
IPC: B65B43/26
Filed: 1981-10-10
Abstract: A push-on device for valve bags, having a gripper for transporting a valve bag from a pile to a filling device, can be made overall simpler, more compact and more mobile, with the aid of gripper forming jaws which are concave on the inside, have lower projecting gripping edges and can be moved together to give a rounded form to the valve, this design thus making it possible, even, if required, in the case of alternating packaging, for a plurality of push-on devices to be made available at a filling device. The gripper here takes on both the task of bag transport and of valve formation. In this case, suction lifters and holding-down devices can support valve formation. The functioning of these elements can, by means of a vertically movable stack carrier, be restricted to a specified working range, and thus be simplified. It is advantageous for the whole unit to be made displaceable by means of an undercarriage.

Patent DE-3218417-A1 (DE)
Title: Process and machine for coating an article
Inventor: ZELLWEGER JUERG
IPC: B05C1/02
Filed: 1982-05-15
Abstract: Machines which coat articles (6) between two rolls (2, 4) arranged vertically one above the other have an upper or application roll (2) which rotates such that its peripheral speed at the place contacting the article is opposed to its forwarding direction (7). The uniformity of application is thereby improved. So that the article (6) is pulled into the narrow gap present between the two rolls (2, 4), it must be turned from its initial position such that it first enters this gap with a region formed by a corner (62). This oblique position results from two conveyor belts (81, 82) running in the same direction but at different speeds (v1, v2). The article (6) is thereby faultlessly drawn through between the two rolls. This arrangement eliminates the need to first separate the two rolls (2, 4) so that the article (6) can enter between them. <IMAGE>

Patent DE-3220936-A1 (DE)
Title: Heavy-load metal dowel
IPC: F16B13/06
Filed: 1982-06-03
Abstract: A heavy-load metal dowel is described, consisting of a threaded tension-bolt and a cohesive slotted expanding sleeve. The threaded bolt is firmly connected to an expanding body with a conical outer surface section, and the expanding sleeve, which extends over a wide region of the masonry recess, has a conical inner surface section into which the expanding body can be inserted by applying tension to the threaded tension-bolt in order to expand the expanding sleeve. The expanding sleeve is continuously slotted and is in surface contact with the expanding body over its entire length region via sawtooth threaded regions of complementary construction. The conical contact surface sections are formed on sides of the threaded tension-bolt from an expanding cone surface which twists helically. The sawtooth thread produced in this manner is, for example, fully stamped-out in the inner region of the tension bolt and, after a plurality of thread turns, runs out into a cylindrical shank section. The advantages of this dowel design are especially the high load capacity and operating reliability which can be achieved with very simple installation.

Title: Method for measuring the velocity of propagation of shock waves
Inventor: BETTERMANN PETER
IPC: G01H5/00
Filed: 1982-06-24
Abstract: A multiplicity of empirical formulae have been developed in order to determine effects of ballistic missiles in the region of their point of impact. The field of application of these formulae is very strongly limited by the multiplicity of different test data. Determining the velocity of propagation of the shock waves is important for predicting the effects of ballistic missiles. The present invention enables measurements of adequate accuracy in concrete. For this purpose, a plurality of electrical measuring sensors are embedded directly in the concrete mass of the component with different directional orientations. The electrical measuring sensors preferably consist of piezoceramic, polarised material and are made from two platelets bonded together having a potential of +/-0 on the external surfaces, and of a centre tap for the signal.

Title: Method and device for the optional automatic interrogation of the detector identification and of the detector measurement value in an alarm signalling system
Inventor: MOSER OTTO-WALTER DIPL ING
IPC: G08C15/00
Filed: 1982-07-05
Abstract: A central station has at least one signalling line (ML) to which one or a number of detectors (M) are connected in a chain. During the cyclic interrogation of the detectors (M), a timing section (T1), which can be influenced by the detector measurement value, is started at a time characteristic of the detector address. During the running time of the associated timing section (T1), control commands for a particular detector (M) on the line (ML) can be generated and received by the relevant detector (M). The control command is used as switch-over command and is evaluated in the detector. During this process, the timing section (T1) is switched from the measurement transducer (MW) to an identification transmitter (R3/R4) and the detector identification, which influences the timing section (T1), is transmitted to the central station with a subsequent interrogation cycle. The switch-over time is set by means of a second timing section (T2) which activates the change-over switch (US). The identification transmitter is formed by a voltage divider (R3/R4), the dividing ratio of which is set as detector identification for the relevant detector. <IMAGE>
Patent DE-3226356-A1 (DE)
Title: Seal
Inventor: GREENWALD FRED A
IPC: B29D99/00
Filed: 1982-07-14
Abstract: An annular rubber seal is manufactured by laying one or more layers (14, 16) of a glass fibre fabric against a surface in the mould cavity of a suitable annular mould. A tubular annular insert (18) of partially vulcanised silicone rubber having a closed annular insert (18) is disposed via the glass fibre fabric in the mould cavity. The dimensions of the tubular insert (18) are chosen such that the helical spring (22) disposed therein leads to the contraction of the insert and to the exertion of a compressive force on the glass fibre fabric. The fabric is thereby held firmly on the surface in the mould cavity. A ring of non-vulcanised silicone rubber is placed in the mould cavity and subsequently the mould cavity is closed and heated to vulcanise the rubber. The seal that this produces has a glass fibre fabric that covers a surface of the seal that is in contact with a workpiece, whilst the helical spring is located in the cavity of the tubular insert and at a distance from the inner surface of the glass fibre fabric. <IMAGE>

Title: Device for determining pressing parameters for the continuous production of chipboards, fibreboards and the like
IPC: B30B5/06
Filed: 1982-09-07
Abstract: Device for determining pressing parameters for the continuous production of chipboards, fibreboards and the like from given pressing material, using a platen press which has an upper press platen, a lower press platen and a press frame. Between the press platens are disposed two press belts, which are supported on the one hand on the lower press platen and on the other hand on the upper press platen so as to be movable. The press belts can be drawn through between the press platens with interposition of the given pressing material when the platen press is closed. The pressing force, draw-through time and pressing temperature are variable, so that the pressing parameters can be determined taking into account the dynamic processes typical for the continuous production of chipboards, fibreboards and the like and the typical heating processes associated with this. A continuously operating press can to a very great extent be simulated in this manner. <IMAGE>
