Title: Resistor manufacture using paper strips - has insulation substrate in which strips are joined to give continuous ribbon for coating
Inventor: LINDNER ALFRED
IPC: H01B3/54
Filed: 1980-07-26
Abstract: The application is to the manufacture of resistors or potentiometers, typically using a resin and carbon mixture for the active material. This is applied onto an insulation substrate of hard paper, typically phenolic bonded. Since the thickness of the required insulation is about 0.4mm it is not readily or conveniently available in reels and has to be cut from sheet. In order to assist the manufacturing process, the cut strips are joined, end to end, to form a continuous ribbon passing through the coating process. After covering the strips are cut up into appropriate lengths. The joining can be done by overlapping and the use of an adhesive bond, by adhesive tape, or by local riveting. The process reduces the amount of manual manipulation required to process the strips through the coating plant.

Title: Battery charger operated from generator - has electronic regulator and RC circuit protecting equipment against transient voltages caused by load changes
Inventor: LACK PETER ING GRAD
IPC: H02J7/16
Filed: 1980-11-06
Abstract: The basic components comprise a generator (G,GEN) a full wave rectifier (GLR) and an electronic voltage regulator (REG) controlling the generator field winding (EW) current. To prevent the regulator, and also the rectifiers, against dangerous voltage transients generated by loads connected to the battery, an RC network (R10,R20,C10) is connected in parallel with the rectified output. The series resistor (R10) has a low value, e.g. 4 ohms. The capacitance is typically 2.2 microfarads, and the capacitor discharge resistance (R20) has about 1000 ohms. The required spike voltage suppression can also be provided by connecting across the input to the regulator. As the additional components are relatively small they can normally be accommodated inside the generator casing. Here they are close to the circuits requiring protection and are also less likely to be tampered with.

Patent DE-3101020-A1 (DE)
Title: Portion dispenser for a liquid medium, and use thereof
Inventor: SCHENKER HANS
IPC: A47K5/12
Filed: 1981-01-15
Abstract: The membrane pump of a portion dispenser for a liquid medium is actuated by a pivotably mounted lever (11) which can be arranged at different bearing points depending on the desired direction of actuation. By pressing in a pump bellows (25), a membrane (53) is pressed in a sealing manner around a suction nozzle (43). When the bellows is released, owing to its inherent elasticity a liquid medium is sucked in through the suction nozzle (43) and a suction connection (47) into the bellows chamber (49) from the medium receptacle (9) located above the nozzle (43). By repeated squeezing of the bellows (25), the membrane (53) is again pressed onto the nozzle (43) and a membrane (59) is raised so that the portion of liquid medium located in the bellows chamber (49) is pressed out of the outlet nozzle (27). After repeated release of the bellows (25), the membrane (59) closes a connection (51) from the nozzle to the bellows chamber to prevent air being sucked in through the nozzle (27). At the same time, by raising the membrane (53) a new portion of liquid medium is received in the bellows chamber (49). The pump bellows (25) and the two membranes (53 and 59) are of integral construction, the portion dispenser or its pump system respectively being of simple construction and readily accessible for maintenance since, owing to the integral construction of the bellows and the membranes, the precise assembly of these three functionally essential parts is ensured. <IMAGE>
