Patent DE-3048479-A1 (DE)
Title: Stagnant water clarification - through gravel filter and open-celled foam layer in enclosed basin
Inventor: SCHULENBURG FRIEDRICH
IPC: C02F3/06
Filed: 1980-12-22
Abstract: Stagnant water in open basins, e.g. for use as aquaria or for drinking water purification, is clarified by passing it though through a gravel filter across its entire bottom area and through an elastic open-celled foam layer into a storage space at the bottom. The water enters a siphon pipe where it is mixed with air and lifted back to the surface of the water level. This achieves a mechanical clarification of stagnant water in enclosed basins without interfering with its development of a natural biological atmosphere in the basin.

Title: Noise suppression during sideways transport of long rolled prods. - by rakes with elastic prongs located between adjacent prods.
Inventor: BOENIG ALBERT ING GRAD
IPC: B65G11/20
Filed: 1980-12-22
Abstract: Rolled tubes or bars roll sideways down a sloping chute or glide surface. To prevent the tubes or bars from hitting each other, and thus creating a large amt. of noise, a row of rakes is located above the chute. Each rake is aligned at 90 deg. w.r.t. the tubes or bars; and on both sides of the rakes are prongs sloping downwards at 45 deg. from the vertical. Each prong consists of a replaceable elastic rod or hose; and the upper ends of the prongs are clamped between two flat plates forming the traverse of the rake. The height and slope of each rake are pref. adjustable. The transport of tubes, etc. along a sloping chute normally causes noise far in excess of the permissible 80 dBA. The invention greatly reduces the noise.

Title: Circuit arrangement for telephone sets with a processor-controlled audio tape cassette deck for automatic answering of incoming calls
Inventor: WAGNER RUDOLF ING GRAD
IPC: H04M1/64
Filed: 1981-02-09
Abstract: It is known for telephone sets to be equipped with a processor-controlled answering machine in which, when a call is received, the deck of a sound recording and playback device is activated in order to convey a pre-recorded text to the calling subscriber. In the invention, this existing device for playback of recorded texts is also used for call recording without incurring substantial additional costs as a result. To achieve this, by inputting into the existing processor a signal identifying the actuation of the hook switch, a signal identifying the desired recording of a call and a signal identifying the insertion into the deck of a cassette provided for recording the call, the processor initiates the coupling of the sound-recording device to the secondary earpiece connection with corresponding activation of a speech amplifier so that a parallel recording of a call in progress can be made.

Title: Curve-straightening roller
Inventor: BECKER ARNO
IPC: D06H3/12
Filed: 1981-08-21
Abstract: A curve-straightening roller (1) is intended for the correction of textile cloth webs distorted in curve form. A number of cone elements (5 to 9) are adjustable in the axial direction (4) on a central roller shaft (2), the circumference (circumferential casing 3) of the straightening roller being formed by flexible circumferential elements (10) which, at some points over their axial length, are held in contact with the cone elements (5 to 9) by means of spring elements (11). These cone elements (5 to 9) are mounted individually on the shaft (2) and are connected to one another in a skeleton construction via connecting rods (17), whilst circumferential elements (10) located respectively opposite one another between the individual cone elements (5 to 9) are connected to one another by means of diametrically arranged tension springs (11). This results in a relatively light curve-straightening roller, in which the flexible circumferential elements can be held reliably in contact with the cone elements even for a relatively long operating time and at relatively high roller speeds. <IMAGE>

Title: Electronic send-receive changeover switch
Inventor: STRUBEL GERT DIPL ING
IPC: H04B1/44
Filed: 1982-02-05
Abstract: The invention relates to an electronic send-receive switch for a transceiver, in particular for the short-wave range, which uses current-controlled diodes and in which reciprocal decoupling of the control circuits from the radio-frequency signal path is effected by decoupling networks comprising coupling capacitors and high-frequency chokes. In order to minimise the technical cost of the control device in terms of fast charge reversal of the coupling capacitors on switching over from transmission to reception and vice versa, it is proposed that transistor constant current sources (SQ1, SQ2 ... SQ4, WR) which can be controlled by a changeover signal (st) and which are in each case designed for a control current which is the maximum permissible for the transistors, are allocated in the control device (ST) to the diode control circuits. <IMAGE>
