Patent DE-3623764-A1 (DE)
Title: Pull-out table with a rotatable extension leaf
Inventor: HECKMANN PETER
IPC: A47B1/02
Filed: 1986-07-15
Abstract: A pull-out table consists of two table leaves lying on a frame and of an extension leaf arranged rotated underneath. The table leaves can be moved apart jointly from one another in the horizontal direction by means of a coupling device by displacement of one of the two table leaves by an operator. The coupling device serves as rotary drive for the extension leaf. The extension leaf and a part of the coupling device are held on the frame so that they can pivot about a vertical pin which is also vertically displaceable. By means of the coupling device, the extension leaf is rotated out of a rest position through approximately 90 DEG  into a raisable position and is raised to the level of the table leaf. The rotational movement of the extension leaf is essentially effected by a U-shaped driver which catches a driving pin fixed on the extension leaf. The driver is pivotable about a pivot axis, parallel to the driving pin, in a limited angular range, in such a way that the driving pin is reliably caught by the driver when the table leaves are pushed together and the extension leaf swivels into its rest position.

Patent DE-3636487-A1 (DE)
Inventor: DUSEL ROBERT O
IPC: G01N21/892
Filed: 1986-10-27
Abstract: Wire processing apparatus employs a conveyor for transporting wire segments to a series of wire processing machines which strip insulation from the wire segment ends and then subsequently attach electric terminals to the stripped ends. A quality control device located between the insulation stripper machine and the terminal attachment machine inspects each stripped end and, if it does not meet desired tolerances, sends signals which prevent the terminal attachment machine from operating upon the defective stripped end as the conveyor moves the wire segment therepast. The quality control device comprises an illuminated field at which the stripped end momentarily stops, an optical lens opposite the illuminated field for providing an optical image of the stripped end, and a converter for converting the optical image to an electronic image signal. Solid state electronic circuits compare the image signal to a reference signal, provide an error signal if the stripped end is defective and store the error signal in a memory circuit. The error signal, if present, is recalled from the memory at the appropriate time and converted to an output signal which prevents the downstream terminal attachment machine from operating on the defective wire end.

Title: Controllable alternating-current source for ozone generation
Inventor: FENDER M PROF DIPL ING
IPC: C01B13/11
Filed: 1987-07-25
Abstract: The generation of the gas ozone is performed by nonindependent electrical discharges between 2 electrodes in air or pure oxygen. The transition to independent discharge (arcing) prevents using an insulating layer of glass in the case of many devices. The invention makes it possible for the ozone generator to be of a smaller design and more efficient, because a converter with a high-frequency rectangular current can reverse the charge of the capacitance of the ozone generator faster. Furthermore, the invention offers the advantage of infinitely variable controllability of the power consumption and a current consumption from the supply system which is lower by a factor of 2 or more. In contrast to other methods, virtually no reactive power is drawn from the supply system.

Title: Digital correlator circuit
Inventor: BAUER HERBERT DIPL ING
IPC: H04B1/707
Filed: 1987-10-19
Abstract: In the digital correlator circuit, which is highly integrated using CMOS gate array technology in chip form, an arriving signal sequence which is stored in an n-stage data input register (7) is compared with a reference signal sequence which is stored in an n-stage reference data register (1), using n multiplier elements (6) and a summation circuit (11) to form a correlation sum. The correlator circuit has as a reference data register, as well as a reference data main register (4), a separately clocked reference data input register (2) for code pattern variation, and as well as the data input register (7), a serially programmable mask register (9), which makes code length adaptation possible, in combination with AND gates (1). Additionally, partial summation circuits (12) for receiving partial correlation sums, and a binary addition network (22) for cascading of several correlator circuits, can be added into the integrated component. The digital correlator circuit according to the invention is suitable for use in correlation receivers with matched filter, particularly spread spectrum message transmission systems. <IMAGE>

Abstract: A helical compression spring (3), particularly for a wheel suspension, is presented and specified, with a spring strut  having a shock absorber and the helical compression spring (3) and connected on one side to the body and on the other to the wheel, and with a transverse control arm. 
<??>When the helical compression spring (3) according to the invention is used on a wheel suspension, the transverse forces occurring on the piston rod of the shock absorber are reduced in that the helical compression spring (3) has a curved spring centre line (7) in the unloaded state. Owing to the fact that the spring centre line (7) is curved, transverse forces (FX, FY) and moments (MO, MU) are initiated as a result of which the line of application (9) of the spring force does not coincide with the spring centre line (7).

IPC: G01R19/255
Filed: 1988-03-03
Abstract: The invention relates to a binary voltage monitor for AC power controllers, which generates from binary converter signals, such as triggering delay and control period, a floating digital actual value of the output voltage with the aid of a simulating circuit. The non-linearities in the control characteristic of non-commutating converters are taken into consideration. Intermediate analog steps (sensors) are not required so that the hardware expenditure is extremely low. The monitor can be implemented without problems in digital voltage control loops. In binary voltage monitors, there is no restriction with respect to drive power and dependencies on parameter fluctuations of the load. <IMAGE>
