Title: DC voltage converter for battery charge transfer - has rectifier, transformer and static inverter with four SCRs
Inventor: WIRTZ RAINER DIPL ING
IPC: H02M3/315
Filed: 1974-11-28
Abstract: The direct voltage converter for transferring charge between batteries of different terminal voltages has a static inverter coupled via a transformer to a rectifier. The static inverter consists of four semi-conductor controlled rectifiers (23-26) connected to form a bridge with a capacitor (28) in one diagonal. The rectifier is so poled that it supplies current to one battery when the transformer (12) magnetic field collapses. The controlled rectifiers are controlled from a variable frequency oscillator (31), which is itself controlled (40) in conjunction with the rectifier output voltage. The advantage of this converter arrangement lies in its giving maximum reliability and optimum energy transfer.

Title: Motor boat berthing stage layout - with stage components set up side to end in Z pattern
Inventor: CHRIST-ESCHERICH GEB ESCHERICH
IPC: E02B3/06
Filed: 1975-03-01
Abstract: In this stage layout for bringing boats alongside, the series of stage components are laid one against another in a Z-pattern. By arranging them in this way the effect is produced of making the berthing length for the sports motor boats etc. longer by the width of a stage in each core. By this means an optimal mooring density is attained, corresponding to the T-shape of a stage layout. This is esp. suitable for low speeds of flow, with the arrangement of floats and boats setting up a tow effect, drawing away from the land. The approach for boats, is easier than with boxes lying across the direction of travel.

Title: AC pulses separation system - uses rectifying and smoothing system connected to two thyristors and circuit containing capacitors and diodes
IPC: H02M5/44
Filed: 1975-07-16
Abstract: Input voltages at terminals (A, B) are rectified, smoothed and applied by a thyristor (Th 1) to isolating capacitors (C1-C4). After a time (tx) has elapsed, the first thyristor (Th 1) is blocked and the second thyristor (Th 2) is ignited so that a discharge current flows from the positive electrode of the capacitor (C1) through the second thyristor (Th 2), capacitors (C4, C3) diode (D7), load resistor (RL), diode (D10) and capacitor (C2) to the negative electrode of (C1). Connections between capacitors (C1, C2) and (C4, C3) are earthed for positive voltage through diodes (D5, D6). When one of the terminals (B) is earthed, a diode (D2) ensures the blocking of negative input voltages, and when terminal the second terminal (A) is earthed, this is done by diode (D1).

Patent DE-2604933-A1 (DE)
Title: Plunger valve with chamfered bottom edge - resting against a combination of a resilient seal and a rigid disc
Inventor: SCHMIDT KURT ROBERT
IPC: F16K21/04
Filed: 1976-02-09
Abstract: The primary closing force originating from the media pressure and acting onto the bottom surface of the hollow plunger (10) is counteracted by a pressure from fluid which found its way from the hollow plunger (10) via ports (11) to the ring-shaped space (12), further, through a notch (27) in the rigid disc (26) to the ring space (24). If pressure builds up in this space the fluid can only escape through a slit between the chamfered plunger edge and the correspondingly shaped seat of the resilient seal (23). It is to be noted that at the moment, when the flutter of the valve might occur, the slit is actually existent, so the fluid has a possibility to escape through the slit and exert opposite pressure on the plunger face.

Both inputs (1, 2) for the rectangular oscillations (f1, f2) are connected with each other through a NOR gate (11), and to the clock pulse input (8) of the second flip-flop (4) whose output (10) is the generator output (12).
Patent DE-2615364-A1 (DE)
Title: Welding implement for contact and contact support - has drive forcing moving electrode to support against spring force
Inventor: BIHLER OTTO
IPC: H01H11/04
Filed: 1976-04-08
Abstract: The implement uses two welding electrodes, one stationary on the metal support and the other one being movable to and from the support by a drive, as in 245804. The drive moves the second welding electrode (9) towards the support (13) by means of a spring (31) engaging the drive. The spring is prestressed by a latching device (19-21). The latching device limits the spring movement in the direction of the welding electrode. The spring and the prestressing force are rated for a drive independent pressing movement. Thus the moving electrode can be translated by the spring from the position, defined by the latching device, into a position pressing the contact blank (11) against the support.

Title: Pen recorder reference mark detection system - uses opto-electronic scanner and electronic signal evaluation circuit for detection of recorder error
Inventor: WINTER KURT DIPL ING
IPC: B65H23/04
Filed: 1976-09-28
Abstract: The device for recognition of a pen recorder reference marking achieves marker detection without use of a cylinder rotation sensor. The markers are detected by an optoelectronic sensor and an electronic evaluation circuit generating an impulse each time a marker appears. Markers are used for detection of recorder errors due to deviation. The evaluation circuit uses three time intervals whose durations are dependent on the recorder speed, the intervals between marker event and writing period, and the marker width. The recorded signals and time criteria are combined logically to identify markers.
