Title: Measuring ohmic resistance of measurement object - from currents and voltages of two selectively connected measurement resistors
Inventor: SCHWARZ CHRISTIAN DIPL ING
IPC: G01R27/02
Filed: 1980-12-18
Abstract: The method and circuit are for measuring the ohmic resistance of a measurement object using a measurement voltage which involves the elimination of the effects of additional disturbing d.c. voltages on the object. Two measurement resistors (Rn,Rh) of different values form a two pole circuit (Zp). The two pole circuit resistors can be selectively connected to the measurement object (Uo) via a switch (SL) and the voltages (Un,Un) across them and the corresp. currents (Jh,Jn) flowing through them measured. The internal resistance (Ri) of the measurement object is determined from the ratio of the differences of the two voltage and currents. The use of a relationship eliminates the effect of the stray d.c. voltage. The method may involve measurement only of the voltages and derivation of the currents from the resistor values.

Title: Control device for purging-air consumption in the regeneration of the adsorbent in an appliance for generating dry compressed air
Inventor: BRANDT HERBERT DR ING
IPC: B01D53/26
Filed: 1981-02-21
Abstract: In an appliance for generating dry compressed air, the compressed air coming from a compressor is fed through an adsorber (1) to a compressed-air storage vessel. In the process, the compressed air is freed of its moisture in the adsorber (1) by an adsorbent located therein. Each time after the compressor has been switched off, regeneration of the adsorbent (6) in the adsorber (1), is triggered automatically by means of compressed air being made to flow in reverse through the adsorbent and, in the process, taking up the moisture contained therein, while expanding at the same time, before being discharged into the open. In order to limit the consumption of purging air to the amount absolutely necessary for each particular regeneration operation, a particular control device (13, 14, 15, 16) is provided which has a measuring section (16), which is assigned to the adsorbent (6) in the absorbent container (5), responds to its moisture content and is connected to an electrical switching device (13). By means of the latter, a magnetic valve (11) positioned on the adsorbent container (5) or a separator (4) downstream thereof is opened only when the compressor is switched off, but is automatically closed when a predefined degree of dryness of the adsorbent has been reached. <IMAGE>

Patent DE-3109072-A1 (DE)
Title: Device for adjusting video signals
Inventor: KAMMOTO YOSHIAKI
IPC: H04N1/407
Filed: 1981-03-10
Abstract: A sensor (S1) is provided in a reflector (23) which reflects light from a lamp (21) in order to illuminate an original (24) for scanning purposes. A light image of the original (24) is optoelectronically scanned, generating corresponding video signals. The sensor (S1) receives light from the lamp (21) and light reflected from the original (24); its output signal corresponds to a logic function of the degree of background density of the original (24) and of the light intensity of the lamp (21). The sensor output is used for controlling the gain factor of a video signal amplifier in order to obtain a constant mean value of its output. The background level is removed from the video signals by an operational amplifier subtracting the video signals from the output of a crest-value latching circuit. The crest-value latching circuit also logically combines the video signals with a reference value. A variable voltage divider is connected to the output of the operational amplifier and is manually adjustable in order to compensate for different patterns of the original. <IMAGE>

Title: Dot-matrix printer with a print head which can be moved along a recording carrier in the print-line direction
Inventor: JOHANNSEN FRED ING GRAD
IPC: B41J2/51
Filed: 1981-06-27
Abstract: In dot-matrix printers, dot formation members arranged in the print head (3) in the manner of a matrix are activated during a relative movement between this print head (3) and a recording carrier (1) in such a manner that selected graphic characters or symbols are produced. In order in this process to produce graphic characters with as many high quality, i.e. with character lines as possible passing through, a high dot density is required. This in turn requires a corresponding number of dot formation members, and, as a result, the print head (3) has rather large dimensions and is too expensive for normal correspondence machines. The number of the dot formation members is reduced according to the invention by virtue of the fact that in a first pass along the print line the dot formation members produce coarse-screened graphic characters and in a subsequent, second pass, using the half-tone dots still stored in the memory unit, produce dots in the gaps between the dots of the coarse-screened graphic characters. The switching movement of the print head (3) between the two passes takes place by parallel lifting of the guide rails (15, 17), arranged along the recording carrier (1), and hence lifting of the print head (3). This simple control device is cost-effective and of simple construction, the dimensions of the rapidly movable print head (3) not being increased. <IMAGE>
