Inventor: AUGUST FRANTISEK
IPC: D03D47/26
Filed: 1976-08-25
Abstract: The bobbin is set in rotation in the winding position by a driving disc (7) pressed against the upper flange (6) of the bobbin and belonging to a winding unit (5). Provided at the same time under the upper flange (6) in the winding body (11) of the bobbin (4) is a flute (16) which is intended for the start of the weft thread (2) to be wound and the bottom (17) of which is located below a plane formed by the outer lower edge (15) of the upper flange (6), above the flute (16) a lower wall (18) of the upper flange (6) being conical at least in the lower part limited by the plane (14). The weft thread is thereby directed in the said plane towards the conical face of the lower wall of the upper flange of the bobbin as early as the start of winding and slips off via this face into the flute. The first weft-thread turn is initially trapped in the latter and continues to be secured by subsequent turns, so that any premature loosening of the weft-thread end during weft insertion into the shed is prevented.   <IMAGE>

Title: Adjustable check valve used in e.g. desalination plant - has stepped plunger with blind axial drilling working with stationary valve needle
Inventor: TIMM HANS
IPC: F16K17/04
Filed: 1976-08-30
Abstract: The adjustable check valve is for the discharge of media from a system such as a water desalinisation plant, where the system pressure has to be kept at a constant level. It has a control plunger sliding in an axial bore in the valve housing towards the open position under the action of the pressure in the system, in opposition to an adjustable spring. The plunger is of stepped section and contains a blind axial drilling with radial ports near a peripheral groove in the piston, permanently communicating with the valve outlet. The drilling works in conjunction with a stationary needle valve determining the cross-sectional area through which flow takes place. The force exerted by the spring shuts the needle valve, and the constant pressure at the valve inlet acts against the end of the plunger nearest the needle valve so as to open it, and against the opposite and smaller end so as to shut it.

Patent DE-2643896-A1 (DE)
Title: Control of inverter intermediate circuit - has variable limit on inverter phase conduction time for three-phase motor drive
Inventor: LINDEN WILHELM DIPL ING
IPC: H02M7/527
Filed: 1976-09-29
Abstract: The voltage appearing at the a.c. terminals is dependent on the conduction time of thyristors in each phase of the inverter. The conduction time is set by varying the instant at which commutation arts. The thyristors are rendered conductive at zero degrees, but as conduction periods under 60 deg. result in zero voltage output the timing signal, typically or ramp voltage, does not start until 60 deg. have elapsed. When the tamp voltage is equal to a variable preset bias voltage the commutating circuit is triggered. By varying the bias the conduction time can be set between 60 deg. and 180 deg. This limiting of the conduction period also allows the addition of an effective overcurrent control.
