Patent DE-2059140-B2 (DE)
Title: Electronic switch has operational amplifier - and has FET switch connecting output and inverting input
IPC: H03K17/06
Filed: 1970-12-01
Abstract: The electronic switch has an operational amplifier with a high open-circuit gain, high input impedance and low output impedance. Two circuits are givne: the first has the amplifier inverting input coupled both to the input signal and over a series resistor and a FET switch to the amplifier output. The two inputs of the amplifier form the inputs of the electronic switch. The second circuit has two switches instead of one. The first switch is located as ain the first circuit and the second isn in series in the amplifier output. Here, the non-inverting input is used as one signal input -- and as before the two inputs of the amplifier form the electronic switch inputs.

Title: Alarm system with several transducers - has microphone pick-up alarm units fed to various evaluation ccts. and coupled to common output response
IPC: G08B13/16
Filed: 1971-01-11
Abstract: The alarm system includes an input transducer (12), typically a microphone connected to an amplifier (14) and a detector (16) with a feedback loop (18). The detector (18) leads to a quantisator (19) comprising a differentiator (20) and a pulse generator (22). The evaluation technique results from a pulse counter including a capacitor-resistor charge-discharge circuit (24) and a level detector (26). Following the latter is a control circuit and an alarm signal unit. A typical alarm installation system includes several similar basic units (10) each with different evaluation characteristics and connected to a comon terminal (34) and incorporating a blocking signal to quench reaction from inactive circuits once one circuit becomes active.
Patent DE-2127579-B2 (DE)
Title: Gas lasers gas-discharge excitation lamp - has slot allowing plasma to leave tube to reduce wall temp.
IPC: H01S3/092
Filed: 1971-06-03
Abstract: The gas-discharge lamp, for exciting gas lasers, consists of a tube parallel to the tube that contains the laser medium. The discharge tube's electrode assemblies lie at right angles to the tube axis and on the opposite side of the tube from the laser medium. The discharge tube has a slot running along its length directly opposite the laser tube. The slot allows part of the discharge lamp's plasma to flow out of the discharge tube around the glass laser tube so that the temperature of the discharge tube walls is reduced - which allows the power and the lifetime to be increased. The two tubes are enclosed in an outer tube with a reflecting surface.
Patent DE-2163914-B2 (DE)
Title: Automatic frequency control circuit - uses three-level threshold and logic to control motor that tunes oscillator
IPC: H03L7/12
Filed: 1971-12-22
Abstract: The automatic frequency controls uses a motor to tune an oscillator w.r.t. a reference frequency in as short a time as possible and with relatively few components. A three-level threshold circuit receives at its input a d. c. voltage proportional to the oscillator's frequency and another proportional to the ref. freq. and is connected at its output to a logic circuit. The logic circuit switches two control voltages for opposite directions of motor rotation through to the motor's control circuit in response to signals falling within the upper and lower parts of the 3-level threshold circuit.
Patent DE-2207045-B2 (DE)
Title: Tapping attachment for a nibbling machine - is driven by an additional drive motor
IPC: B26F1/04
Filed: 1972-02-15
Abstract: The tapping attachment can be used on a punching or nibbling machine. This tapping attachment taps holes in the workpieces produced on the nibbling machines without resetting. The tapping hole is produced by the punching tool and the hole is subsequently tapped by this attachment. The tapping tool is coupled to a drive motor and in this case the tapping hole is not necessarily produced by punching. The drive motor can be swung out of the working position and in another preferred version the tapping tool can be guided by a guiding screw. A disc shaped fixture (18) has a central guiding thread (19) which is held in the punching machine (21). This attachment is used instead of the usually used die of the punching tool. The drive motor (22) is connected by a square hole (23) with the square shank (16) of the tap (13).

Abstract: PURPOSE:To obtain a plastic film joining equipment equipped with a powder dusting device, which does not blow up excess powder as dust at the time of dusting, by a method wherein powder is uniformly adhered to the surfaces of films by utilizing static electricity, which is charged onto the films, at the time of joining of the films in continuous form. CONSTITUTION:The side ends of respective films (a), (b) and (c), which are overlapped with each other, are fusion-welded each other on a table 11 by high frequency induction heating developed with a bonding device 4. At the same time, static electricity is charged onto the welded films. Next, powder, which is positively charged by means of corona discharge developed between the discharge electrode 23 and the earth electrode 24 of a first powder dusting device 5 is blown by the forced draft of a blower 15 against the underside of the welded films so as to attract the power by means of the negative static electricity charged on the respective films, and the powder is adhered onto the underside of the films. Next, the powder, which is positively charged with a second powder dusting device 6, is blown against the top surface of the films, the powder is attracted by means of the enfeebled static electricity on the film side, and the powder is attracted onto the top surface of the films by means of the forced draft of the blower 15 and the own weight of the powder.

Patent JP-S6211601-B2 (JP)
IPC: B01D9/00
Filed: 1982-03-29
Abstract: A crystallizing apparatus particularly for use with undercooled melts. Crystallizing is effected on the cooling conveyor belt in a thick layer. A precrystallizer comprises at least two rolls arranged above the cooling conveyor and rotating in the same direction. A shear gap is formed between the at least two rolls. A melt is applied to an uppermost one of the at least two rolls in a thin layer. In the course of the path followed by the melt over the at least two rolls, shearing forces are generated within the area of the shear gap, which enhance the nucleation. A further enhancement of nucleation is obtained by cooling the at least two rolls, so that relatively large volumes of the melt may be crystallized per unit time in the crystallizing apparatus without the need for the addition of supplemental seed crystals to the melt. The amount of melt in the precrystallizer is very small.

Abstract: In a radio communication device of a CDMA system selectively operable in high and low power modes to receive a reception analog signal and to produce a demodulated signal, an A/D converter is controlled to reduce power consumption in the low power mode in comparison with the high power mode. The reduction of power consumption can be established by partially operating the A/D converter or by lowering a sample rate in the low power mode. A despreading portion connected to the A/D converter is also controlled in a manner similar to the A/D converter. Each of the high and the low power modes is indicated by a mode control signal produced by a CPU controller. <IMAGE>
