Patent DE-3100503-A1 (DE)
Title: Arrangement for monitoring the charge state of a battery
Inventor: ECKERT WERNER ING GRAD
IPC: H01M10/48
Filed: 1981-01-09
Abstract: It is proposed that the charging time of a capacitor which is connected in the battery circuit be measured and that a liquid-crystal display be driven using a voltage signal obtained from this charging time. The display has a plurality of display elements; the number of driven display elements is a measure of the discharge level of the battery. Since the charging time is highly dependent on the battery voltage, the proposed monitoring is very sensitive; in particular, the user is warned of an incipient battery failure in good time. The arrangement is primarily suitable for apparatuses which already have a charging capacitor and/or a passive electrooptical display. Preferred example of use: electronic flash equipment. <IMAGE>

Title: Circuit arrangement for a telephone station powered via the subscriber line
Inventor: GOERLITZ HANS DIPL ING
IPC: H04M1/60
Filed: 1981-03-24
Abstract: The invention relates to a circuit arrangement for a telephone station powered via the subscriber line with a microphone amplifier and with a logic system which controls the dialling procedure and the loop interruption. The DC voltage supply is made polarity-independent by a Graetz rectifier bridge. The intended object of the invention is to activate the microphone amplifier in such a way that it requires minimal power. This is achieved by activating the microphone amplifier via an MOS component in such a way that it is disconnected from the power supply, even during the short periods in which it is not required. This also concerns in particular the periods of loop interruptions by the dial pulse contact. The circuit arrangement according to the invention is suitable for every subscriber station with remotely powered amplifiers.

Title: Interruptor switch
Inventor: SALETTA GARY F
IPC: H02H3/10
Filed: 1981-04-08
Abstract: An interruptor switch analyses the electrical conditions prevailing in a circuit to be protected and switches the circuit off if the electrical conditions exceed predetermined limits. The interruptor switch (32) contains a tripping unit (which has a microcomputer), a device for sensing the current flowing through the interruptor switch, a device for converting the analog values into digital values to be used by the microcomputer, and a read/write chip (82) which is detachably inserted in the front panel (26) of the interruptor switch and is used for storing parameters relating to the time/current tripping characteristic of the interruptor switch. The interruptor switch furthermore contains a numerical display (80) via which the microcomputer successively displays numerical values which correspond to the prevailing electrical conditions; furthermore, parameters are displayed which define the time-dependent tripping characteristic of the interruptor switch. After the interruptor switch has tripped, a plurality of light-emitting diode displays (84, 86, 88) provide a subsequent indication of the cause of the tripping and of the tripping current intensity. A memory unit stores the level of the phase current or earth current leading to tripping, and this value is displayed in conjunction with tripping. The display of a single-digit numerical value provides information on the cause of tripping. Means are provided for carrying out tripping with a long delay and tripping in the event of an earth short, with high accuracy. Reliable operation is guaranteed when the supply voltage is applied. The voltage supply supplies voltage for the tripping unit even after tripping has taken place. <IMAGE>

Title: Circuit arrangement for a stored-program process controller
Inventor: BACHMANN LUDWIG DIPL ING
IPC: G05B19/045
Filed: 1981-06-16
Abstract: The circuit arrangement is used, in particular, for dealing with the input and output information in computer-controlled machining processes. Due to the invention, the machining speed is to be increased in such controllers. For this purpose, a circuit arrangement for freely programmable controllers is to be created by means of which their basic configuration is changed in such a manner that simple information which can be rapidly provided is processed in a shorter cycle time. To achieve this object, a second logic unit and a switch-over device is added to the configuration of input and output buffer memories, logic control unit, main memory and sequence control unit. To process simple information which is to be provided rapidly, the second logic control unit is connected to the inputs intended for this purpose and is called up by the first logic control unit via masking connections. The switch-over device alternately switches the outputs of the first and of the second logic control unit to the output buffer memory. The second logic control unit is activated by a central clock unit in shorter clock cycles than the first logic control unit is activated by the sequence control unit.
Patent DE-3127217-A1 (DE)
Title: Combined cross-cut and circular table saw
Inventor: NICKE WOLFGANG DIPL ING
IPC: B23D47/12
Filed: 1981-07-10
Abstract: A combined cross-cut and circular table saw, in which the saw device can be swung into a position in which it is located spatially above the bearing surface of the saw table top (cross-cut position) and into such a position in which it lies below the saw table top (use as circular saw) and in which the saw device can be rotated by means of a rotary table and can be latched in defined rotary positions, is to be improved to the effect that the conversion of the saw from the application as a cross-cut saw to the application as a circular table saw is simplified and at the same time the pivoted-lever arm is lengthened. This is achieved in that the rotary table is provided on its underside with a bearing point around which the saw device with the associated drive motor, which at the same time serves as a counterweight to the saw, can be pivoted in a plane running perpendicularly to the plane of the rotary table, and in that a recess which can be covered is made in the rotary table, through which recess the part of the saw device located on the side of the bearing point can be swung, in the course of which the part of the saw device lying on the other side of the bearing point, including the drive motor, always remains under the table surface in each position of the saw device. <IMAGE>

Patent DE-3213015-A1 (DE)
Title: Electronic balance having a plurality of operating modes
Inventor: KNOTHE ERICH ING GRAD
IPC: G01G7/02
Filed: 1982-04-07
Abstract: Electronic balances having a plurality of operating modes have hitherto required comprehensive mechanical operating elements, for example in the form of a keyboard, in order to select the program suitable for the desired operating mode. Now the invention is intended to allow the selection of the desired program without these additional operating elements. For this purpose, there are provided a non-volatile electronic memory (17) and a counter (18) which, together with an operating element present as standard on the balance, namely the tare key, make it possible to select the desired program as follows: if this operating element is actuated at the same time as when the supply voltage is switched on, the counter (18) is activated in a menu program and counts through all the program numbers slowly. The counter (18) is stopped at the number of the desired program by a further actuation of the operating element, and this program number is transmitted to the non-volative electronic memory (17). The program fixed in this way is used, irrespective of whether the supply voltage is switched off and on again in the meantime, until a new program number is selected by a new call-up of the menu program. <IMAGE>

Title: Video device for recording and replaying 3-D video films and doubling the recording time and endless reproduction of video signals
Inventor: NEUMANN CARL WERNER
IPC: H04N5/7826
Filed: 1982-09-21
Abstract: The present device has the object of storing and replaying video films in 3-D, but also to render these video films playable for other video devices. This is achieved by separately recording the right-hand and left-hand channel through a head pair which is arranged in such a manner that it records or plays the upper half (left-hand camera) and a head pair which records or plays the other half (right-hand camera) of the video tape simultaneously, as the result of which, when only one channel is played on a currently commercially available video device of the 2000 system, a full frame appears in full colour on the screen of a television set or of a video movie screen. Furthermore, this device is capable of doubling the recording time on a "turn-over" cassette and to provide the possibility for endless replaying which is achieved by the head player which, allocated to the lower half of the tape, additionally records or plays this lower half of the tape whilst tape and head drum are running backward. Particularly suitable for video movie theatres and advertising.
