Patent DE-3336506-A1 (DE)
Title: Method for producing a detachable connection of two surfaces, and a connecting element for carrying out the method
Inventor: DOERIG WERNER
IPC: E04B1/61
Filed: 1983-10-07
Abstract: A circular, cylindrical depression is drilled at a predetermined point on the surface of the first component (12) which comes to rest on the second component (13). A circular marking gauge is inserted into this depression with its centring tip upwards. The first component (12) is now pressed against the second component (13), in the correct position. A depression is again drilled into this impression. In each case one circular, pot-shaped connecting piece (1) is mounted by means of screws, which are screwed-in through holes (6), both in the depression in the first component (12) and in the depression in the second component (13). Located in the central region of each of the connecting pieces (1) is a projecting wedge hook (3), the two wedge hooks (3) being offset through 180 DEG  with respect to one another and, when hooked together, forming a can-shaped connecting element (11). Four centring studs (2) on the circumference of the connecting pieces (1) are used for the precise positioning of the connecting pieces (1) in the component depressions. <IMAGE>

Patent DE-3341066-A1 (DE)
Title: Thermal imager
Inventor: WEIGEL WOLFGANG
IPC: G02B26/10
Filed: 1983-11-12
Abstract: The thermal imager uses a scanning mirror (2) in order to guide incident radiation onto the detector row arrangement (4) which after optoelectronic conversion drives the row arrangement (6) of light-emitting diodes in a time-synchronous fashion; this image is represented via the rear of the scanning mirror on the imaging optics (9). Provided on the reproduction side is a scan position sensor (12) with the light source (12/1) and the detector (12/2) above a beam splitter (12/4) in the image plane of the collimator lens (12/3). Since, on the one hand, the spectral splitter (7) is arranged between the scanning mirror and the row arrangement of light-emitting diodes and, on the other hand, the spectral splitter (8) is arranged between the scanning mirror and the scan position sensor - both splitters reflecting the emission of the light source in the direction of the scanning mirror - the light source can be imaged on the associated detector in the event of a specific mirror setting, something which signifies autocollimation. This detector signal therefore represents a specific mirror setting. It is advantageous that such a sensor can be arranged with respect to the direction of its beam course at any angle differing from 90 DEG  relative to the scanning mirror (Fig. 1). <IMAGE>

Title: Apparatus for producing a mixture of at least two fluids with a defined mixing ratio
IPC: B01F15/04
Filed: 1983-12-05
Abstract: A mixing apparatus for producing a mixture of a base fluid and at least one further fluid with a defined mixing ratio comprises a proportioning device with a main plunger having a plunger rod (11) on which a proportioning plunger (103) is arranged so as to be axially movable. The proportioning plunger (103) can move in a cylinder (101) and, together with the cylinder end face, forms a proportioning chamber (55). The plunger rod (100) extends through the proportioning plunger (103) and has a free end (120) which can engage a projection (117) on an actuating sleeve (115). The actuating sleeve (115) is screwed onto a threaded sleeve (114) in such a way that its axial position can be changed relative to the threaded sleeve. The threaded sleeve (114) is fixed to an expanded-diameter section (107) which is formed on one end of the proportioning plunger (103) projecting from the proportioning cylinder (101). Acting between the end (120) of the plunger rod (100) and the proportioning plunger (103) there is a spring (111). The maximum volume formed of the proportioning chamber (55), when the plunger rod (100) moves from one end position into the other end position, is defined by the axial position of the projection (117) on the actuating sleeve (115) in relation to the proportioning plunger (103). <IMAGE>

Title: Circuit arrangement for an electronic choke in loudspeaker telephone stations
Inventor: BLOSSFELDT DIETER DIPL ING
IPC: H04M1/60
Filed: 1984-02-28
Abstract: The invention relates to an electronic choke for loudspeaker telephone stations with remote feed and pulse transmission via the speech wire pair, the choke being inserted in the speech wire pair between speech signal transmission and speech signal evaluation devices. The intended object is to produce a choke circuit which prevents AC signals from being short-circuited via the relatively low-impedance loudspeaker telephone station circuit connected to the feed, including a maximum choke input switching voltage without high feed load and an adequate power supply for short-time higher load. This is achieved by means of a circuit arrangement of the type indicated in the characterising part of claim 1, whereby a high control capacity of the control elements is achieved, as well as a high input resistance of the feed input of the station circuit for pulses, a high control voltage of the control elements through voltage duplication circuits without feed load and a power buffer storage through corresponding capacitors. The use of choke circuits of this type is appropriate in telephone stations in which remote feed and pulse transmission are performed via the same pair of wires and in which minimum power is required.

Title: Method for parallel transmission of binary digital signals
Inventor: WELLHAUSEN HANS-WERNER DIPL IN
IPC: H04L25/49
Filed: 1985-06-13
Abstract: A method is described for parallel transmission of binary digital signals at around 2 Mbit/s via separate conductor pairs of a common local cable. The two or more bits of the binary digital signal converted in a coder (C) into a redundancy-free or low-redundancy quaternary digital signal are adapted by two baluns (Sy 1; Sy 2) to one conductor pair (L) of a balanced local cable (Fig. 1). Following the transmission of the converted quaternary signal, a feedback known per se is carried out at the receiving end in order to recover the low-frequency spectral components lost on the transmission path and, in addition, to reduce the near-end and far-end crosstalk and pulse noise. <IMAGE>

Title: Method and device for suppressing jammers in the field of view of a location apparatus which is used for command guidance of missiles
Inventor: SCHWELLINGER ULRICH
IPC: F41G7/30
Filed: 1985-12-05
Abstract: The invention relates to a method and to a device for suppressing jammers in the field of view of a location apparatus (1) which is used for the command guidance of missiles and whose field of view is limited to a window surrounding the missile. In order to suppress the jamming of the missile guidance even when a jammer enters the limited field of view of the location apparatus (1), the guidance commands for the missile are produced, according to the invention, using estimated values for the offset ( epsilon ) of the missile with respect to the optical axis of the location apparatus (1). Expected values are formed for the observable measurement variables of the missile, especially the offset or the change with time of this offset, and said expected values are compared with corresponding measured values. If these measured values are within a tolerance band about the expected values, then the calculation of the estimated values for the offset of the missile is assisted by the measured offset, but if the measured values are outside the tolerance band, then the assistance is interrupted. The offset of the missile itself is preferably used as the observable measurement variable, so that the estimated values and the expected values are identical. <IMAGE>
