Patent DE-2414434-A1 (DE)
Title: Parallel box front flap folding mechanism - has parallelogram linkage with lower member raised by incoming box
Inventor: MARCHETTI AUGUSTO
IPC: B65B7/20
Filed: 1974-03-26
Abstract: The boxes are delivered on a supporting surface with a parallelogram linkage above it, the latter comprising a top fixed cross-member, a lower moving one, and two bars, normally vertical, joining them. The lower end of a pendulum arm is attached to the lower member at the inlet end, and a rigid bar is attached between the top member and the pendulum arm. Dimensions of the normally vertical bars of the parallelogram linkage and of the rigid bar are such that the lower member remains constantly at a height above the supporting surface slightly less than that of the box end wall and the pendulum arm is held in a direction extending upwards towards the outlet end of the surface. Thus the thrust froma box against the inlet end of the lower member lifts the latter to a height slightly greater than the box end wall height, and simultaneously tilts the arm into a direction extending upwards and towards the surface inlet end.

Title: A.C. supplied fluorescent lamps and supply cct. - cct. includes starting and brightness control using at least one starter
Inventor: SCHWAB HARTMUT DIPL ING
IPC: H05B41/38
Filed: 1974-05-02
Abstract: Starter function is carried out by a switching network controlled by a device connected to it through a decoupling network with inputs connected to a terminal of the lamp heated electrode, whose other terminal is connected to a series inductance, connected in turn to a supply voltage terminal. The switching network output and the other supply voltage terminal are connected to the other electrodes. After the supply voltage has been applied and the lamp ignited for the first time, the gas discharge path is periodically disconnected for brightness control. When the lamps are periodically disconnected, their discharge paths are short-circuited through the decoupling network and the switching network, while heating current flows through the electrodes.

Title: Circular knitter needle control - has push rods divided into two groups for electro-magnetic operation according to the pattern
Inventor: RIBLER ERICH
IPC: D04B15/78
Filed: 1974-05-17
Abstract: Electrically-operated pattern control unit, for a circular knitter, has push rods arranged intwo groups for positioning in the active or inactive settings. Each group is provided with a control magnet, a prestressed cam and an acivatingcam, with one push rod of each group keyed to the same needle or the sinker activating the needle. The driving cams for the push rods are operated to move the needle or sinker into the tuck or knitting positions. The division of the push rod assembly into two groups reduces the number of needle movements in changing from one operating position to another, increasing their operating life, and increasing productivity as stoppages are reduced, in a simple and cheap construction.

Title: DC flow converter with setting elements with common output - has parallel power ccts. each of setting transistors, transformer, and filter cct
Inventor: KIENBERGER HELMUT DIPL ING
IPC: H02M3/335
Filed: 1974-06-20
Abstract: The direct current flow converter has at least two pulse width controlled setting elements operating to a common output. Parallel power circuits are formed each by a setting transistor, a transformer, and a filter circuit. These circuits are uniformly loaded by the control of current division in the setting elements after comparison of a measuring criterion, tapped from all power components. Preferably the mean value of the voltage pulses at the input of the filter circuits forms the measuring criterion for the control of the current division. A common storage capacitor may be associated with all parallel power circuits. One of these parallel circuits may be controlled via a regulating amplifier in dependence on the control deviation of the output voltage, while the other power circuits may be controlled each by a current division regulator.

Title: Correlation receiver with squaring networks - has networks between subtractors inputs and mixers mixing input with pseudo-random sequences
Inventor: GRUENBERGER GERHARD DR ING
IPC: H04B1/707
Filed: 1975-01-30
Abstract: The correlation receiver has two networks (N) between the outputs of the second and third mixers and the two inputs of the subtraction circuit. The two mixers are supplied with the input signal, and the output of the subtraction circuit forms the output of the correlation network (KN). Each network (N) contains a squaring device in series with a low pass filter at its input. The two pseudo-random sequences generated for mixing with the input signal have a mutual time displacement that is less than their clock period whilst the receiver is synchronised. The advantage lies in sharpening phase discrimination.
