Title: Monorail suspension conveyor stacking wagon - has towing pawl drawing braking pawl into inactive setting, for quiet running
Inventor: ROTHACKER HARRY
IPC: B61B10/02
Filed: 1980-12-19
Abstract: The single rail stacking wagon for suspension conveyors has a pair of moving-carrier pawls for a circular towing chain. The leading pawl can be drawn into an effective position, while the rear one moves over, in the face of a return force by virtue of a deflecting slope. The braking pawl is coupled to the activating mechanism for the towing pawl in such a way that, when the latter is activated, the former is likewise drawn forward into an ineffective position. This eliminates clicking noises, even on conveyors with outside stacking, and with the towing pawl swinging in the direction of travel.
Patent DE-3104558-A1 (DE)
Title: Circuit arrangement for determining the cycle duration of the fundamental oscillation of band-limited and/or errored quasi-periodic signals in real time
Inventor: KUEHLWETTER JUERGEN PROF DR
IPC: G10L25/90
Filed: 1981-02-10
Abstract: The invention achieves the object of determining the cycle duration T0 of the fundamental oscillation from a band-limited and/or errored quasi-periodic signal through hardware implementation in real time. It is an essential feature, particularly in the case of speech and speaker recognition. The basic mode of operation is shown in the Figure. The signal s11 is amplitude-normalised (11) and then manually limited in such a way (12) that noise components no longer occur. The amplitude-normalised signal s14 is squared (14) so that the frequency of the fundamental oscillation and the frequencies of its harmonics are reconstituted. By means of a low-pass filter (15, 16) which is standardised in terms of signal processing to the fundamental frequency f0, the frequency range is limited to the frequency corresponding to three times the fundamental frequency, but not exceeding 500 Hz. With a controllable low-pass filter (16), the signal s17 is then band-limited (20, 17) in such a way that essentially only the fundamental oscillation is fed to the coder (18). From the positive and negative maximum values of the signal s18, the coder (18) generates a binary signal s19 whose cycle duration T0 is measured in the evaluation stage (19). <IMAGE>

Title: Transceiver device for binary data signals to be transmitted in telephone switching systems, in particular in small PBX systems
Inventor: BLOSSFELDT DIETER DIPL ING
IPC: H04L5/14
Filed: 1981-03-31
Abstract: In so-called small telephone PBX systems, binary data signals are transmitted in both directions between a central device (ZE) and the terminal devices (telephone sets (T1-Tn)) connected to it. For transmission of setting information for visual and/or acoustic indicator elements (A) present on the terminal devices, unipolar pulses, which differ from one another in both their pulse amplitude and in their time duration, are transmitted as binary values. For the information to be transmitted in the opposite direction (actuation of keys), a bipolar pulse and a pulse-free condition corresponding to the rest potential of the line serve as binary values. The transmission line is terminated at both ends with a transceiver transformer (Uz, Ut) which has, in addition to the line-side winding (Wz3, Wt3), a transmission winding (Wz2, Wt2) and a reception winding (Wz1, Wt1). Electronic switches (T1 or T2), of which one (T1) is connected directly in series and the other (T2) via a dropping resistor (R8) to the transmission winding (Wz2), which for its part is connected to the supply voltage, can in each case be effectively closed by an associated control unit (STz) in order to generate the unipolar pulses used as binary signals in one transmission direction. In order to generate a bipolar pulse, two electronic switches (T3, T4) are coupled with the transmission winding in such a way that, as a result of the successively performed short-time closure, currents from opposite directions pass through the transmission winding during the closure period. <IMAGE>

Title: Process and device for turning an elastomeric tube inside out and drawing it onto an outer pipe
Inventor: HIRTH ROLAND ING GRAD
IPC: F16F9/084
Filed: 1981-04-25
Abstract: The invention relates to a process and device for turning an elastomeric tube inside out and drawing it onto an outer pipe, preferably onto the outer pipe of a pneumatic spring, and onto an inner pipe, preferably onto the container pipe of a hydraulic shock absorber. The aim of this is to make it possible to turn inside out elastomeric tubes of any kind, in particular however cylindrical elastomeric tubes, and to bring them to at least the external diameter of the outer pipe receiving them without spotwise, non-uniform stretching occurring. The relative movement of the elastomeric tube with respect to a non-elastomeric part is carried out by feeding compressed air as lubricant. This measure is simple and cost-effective and makes it possible to turn inside out elastomeric tubes of any kind and to bring them to specific diameters and keep them in this position.

Filed: 1981-10-16
Abstract: In typewriters or similar office machines having a form-advancing device which can be fitted thereon, the forms to be printed are automatically fed to the platen of the printer. In order to guarantee satisfactory form-guiding, this device must be fitted on with precise adjustment. The paper-guiding trough which is in operative connection with the platen in single-sheet operation must also be lifted by said platen. The operator must therefore carry out some manipulations. In order to avoid malfunctions of the office machine after the form-advancing device has been fitted on, according to the invention its housing (5) has a control face, by means of which the swivel lever (111) for lifting the paper-guiding trough (71) is swivelled automatically by the platen (13). No additional operating sequences are therefore required. The advancing device according to the invention is simple in construction and in handling. <IMAGE>

Title: Atomiser wheel for atomising fluids
Inventor: KRAGH OLE TEGLHUS
IPC: B01D1/20
Filed: 1981-10-28
Abstract: An atomiser wheel (1) has a hub (2), a floor (4), a circumferential wall (5) and a cover (6) which bound a shell-shaped fluid supply chamber (8) in the atomiser wheel (1), an annular opening (7) which serves to supply fluid to the chamber (8) being provided between the cover (6) and the hub (2). Outlet openings for the expulsion of fluid are constructed as a number of channels (9) attached at equally large intervals from one another in the circumferential direction and extending through the floor (4) of the atomiser wheel. As a result, it is ensured that fluid droplets are expelled by the atomiser into a larger area of the space than by known atomiser wheels provided with outlet openings in the side walls, which, together with the movement pattern for the expelled fluid droplets, reduces the probability of a collision of said droplets in the critical phase of the drying process when their surfaces are so sticky that they tend to form agglomerations of two or more bonded drops. As a result, the material density in the dried product can be increased by reducing the intermediate air spaces between the particles of said product. By attaching the channels (9) in such a way that their, viewed in the radial direction, outer boundary (12) is located at a distance inside the inner surface (13) of the circumferential wall (5), the fluid can be centrifuged and air possibly present in it can be driven out, as a result of which the presence of internal cavities in the dried particles can be reduced and the material density of the dried product can be increased. <IMAGE>
