Patent DE-4234874-A1 (DE)
IPC: F28F19/00
Filed: 1992-10-16
Abstract: There exists a cooling device in which the water circuit 6 passes, in a frost-proof building 1, through a buffer container 11, a pump 7 and a heat exchanger 3 and passes, in the frost-endangered outer air 2, through a recooler 8 provided with a blower 10. In this arrangement, it is desirable if evaporation of water from the water circuit is avoided, while preventing water in the recooler from freezing as a result of the outer air. This is achieved in that the water circuit 6 is constructed, in a continuously closed manner, with a closed buffer container and with a recooler 8 having a tube bundle 9, and in that the inlet side 17 of the recooler 8 is connected to the upper side of the buffer container 11 via a switchable ventilation valve 18. By virtue of the ventilation valve, the water circuit can be completely closed, with the recooler being protected against freezing up without antifreezing agents. <IMAGE>

Inventor: KLINGEBIEL KARL-HEINZ
IPC: B65H19/18
Filed: 1993-02-04
Abstract: The invention relates to the preparation of material webs for the purpose of splicing in a bobbin changer. The object is to make the bobbin changer more operationally reliable and more flexible in format adaptation. For this purpose, according to the invention, with the running-off material web (8) being moved, double-adhesive connecting leaves (7) succeeding one another in the transverse direction of the stationary new material web (9) are rolled onto the latter. For this, a longitudinally movable transfer slide (27) draws off a carrier-material strip (21), together with the connecting leaves, from a stock roll (18) by means of a deflecting-roller arrangement (26) and, by means of a pressure roller (28) deflecting the carrier-material strip, rolls the connecting leaves transversely in succession onto the material web (9). The relatively short connecting leaves can be handled without difficulty and can easily be adjusted in terms of their number to the width of the material web. <IMAGE>

Title: Plug-in connection for pipes, hoses or similar round bodies
Inventor: GEHRING PETER
IPC: F16L37/091
Filed: 1993-02-12
Abstract: A plug-in connection (1) for pipes, hoses or other round bodies -also consisting, for example, of hard plastic - has at least one receiving sleeve (3) for the pipe end to be plugged in, and also has any type of retaining device (5) projecting into the inner cross-section of said receiving sleeve, for example a retaining disc designed in the manner of a fan or slit in its radially interior retaining region, in order to be able to yield resiliently with respect to the pipes pushed through it, as a result of the radial pressure exerted by the external diameter of the said pipe. Consequently, said plug-in connection grips the pipe upper side firmly. The pipe (2) is prevented from being drawn back insofar as the slit retaining region of the retaining disc (5) is not, for example, bent away from the pipe upper side by way of a sliding sleeve. Said plug-in connection (1) also exhibits an annular seal which, in the use position, butts against the pipe upper side and is located in the receiving sleeve (3), the unit being held together by a screwing ring (7) which takes effect in the axial direction. In this arrangement, the annular seal is formed from at least two radially compliant or deformable sealing rings (4) which, in the plug-in direction of the pipe (2), are located, one behind the other in the axial direction, in a continuous common clearance, with the result that, accordingly, there are at least two sealing zones lying one behind the other in the axial direction on the plugged-in pipe (2). The capacity for sealing is correspondingly improved. By special configuration of at least the ... in the plug-direction ... Original abstract incomplete. <IMAGE>

Title: Method for demodulating a signal
Inventor: DESAGA GUENTHER
IPC: H04L25/49
Filed: 1993-03-12
Abstract: In a method for demodulating a signal in which the duration of in each case one pulse (H level) specifies the value of one bit, the pulse begins a measurement of the pulse length by a measuring time and a time window being started, the time window being shorter than the measuring time. The signal is sampled at regular intervals which are essentially shorter than the shortest pulse length provided. During the time window, samples are counted which result in the L level, the measurement being terminated when a predetermined number is reached. When the predetermined number is not reached during the time window, the samples which result in the H level are counted up to the end of the measuring time. The value of the bit is output depending on whether the counting result is above or below a limit value. <IMAGE>

Title: Device for switching high voltages and/or high currents and/or high frequencies
Inventor: LAUMER SEBASTIAN
IPC: H01H19/56
Filed: 1993-07-23
Abstract: The invention relates to a high-voltage switch which makes it possible to use advantageous coaxial contact element arrangements, in particular coaxial plug connections, for rotary switches and slide switches as well. The invention envisages a multi-phase movement of at least one contact element or device part, in particular of a rotary switch. A two-phase movement is preferred for switching off and on, which movement comprises an axial linear movement and a coaxial rotary movement. In order to change the polarity of a changeover switch which has, for example, four poles, a three-phase movement of a rotary switch is provided. Flashover of the high switching voltages is largely prevented by means of an appropriate insulator arrangement.
