Title: Telephone line condition testing system - has test and control positions with coding system determining receiving and transmitting modes
Inventor: BRETSCHNEIDER GUENTER DIPL ING
IPC: H04B3/46
Filed: 1979-07-31
Abstract: The addressing system is used with a telephone line in parallel with another line form a data channel for control signals.A series of measuring positions are arranged along the lines, each with a signal transmitter and receiver connected to the lines. These form measuring devices for command signals, operated so that the usual measuring devices act as sub-measuring devices, resulting in commands from both for the same addresses. The sub-measuring units act as receivers and the main units act as transmitters. By determining the main measuring positions, coding and release of the next command signal are obtained.Command and measuring signals are received by an input at each measuring position, each position has a coding and decoding system with a common code.

Title: Catadioptric lens of high speed
Inventor: WIEDEMANN ERWIN DR ING
IPC: G02B17/08
Filed: 1981-05-27
Abstract: The very fast (rapid) catadioptric lens having a relative aperture of 1:1 consists, seen in a direction of the movement of the light, of a converging front lens, a Mangin mirror and a converging field lens, which are separated by air spaces. The catadioptric lens is characterised in that the front lens is biconvex and mirror-coated on the reverse side in its central part, that the field lens is planoconvex and arranged in a central bore of the Mangin mirror, and that all three lenses consist of the same type of glass, so that in each case the catadioptric lens has only eight optically active surfaces. It therefore represents the first example of a spherically, chromatically and anastigmatically corrected triplet with a plane field behind a system which requires for its construction only one type of glass. If the field lens is a component of the Mangin mirror, it has two surfaces which are convex with respect to the incident light. <IMAGE>

Title: Concentration-monitoring instruments, especially CH4-concentration monitoring instrument
Inventor: WOELKE WERNER
IPC: G01N33/00
Filed: 1981-07-11
Abstract: The invention relates to a concentration-monitoring instrument, especially to a CH4-concentration-monitoring instrument which is intended, e.g., for underground mining operations. It is designed for monitoring the concentration of a combustible gas in a mixture of air and combustible gas. Said monitoring instrument has a measuring bridge, of the type of a Wheatstone bridge, a display device which is connected to the bridge diagonal and displays a measured current which can be calibrated in terms of combustible-gas concentration, and an unambiguity device (determinacy device). The measuring bridge in one branch of the bridge has a detector resistor and in another branch has a compensation resistor, the heat of reaction of an oxidation of the combustible gas acting on the detector resistor, but not acting on the compensation resistor which otherwise matches the detector resistor. The unambiguity device operates with an ancillary resistor whose resistance changes as a function of the thermal-conductivity properties of the mixture of air and combustible gas. The device generates an additional measured current which, after reaching a limit value characteristic for the detector resistor, becomes effective on the display device. The unambiguity device consists of an extension bridge which is likewise constructed in the manner of a Wheatstone bridge. It is connected in series with the first mentioned measuring bridge. Situated in one of its bridge branches there is the ancillary resistor, and in the other there is a conventional ohmic resistor. By means of the diagonal, said extension measuring bridge is connected to the display device. The extension measuring bridge thus generates an extension measured current which, after reaching the limit value characteristic for the detector resistor, extends the display up to the concentration value of 100%. <IMAGE>
