Title: Warning sign and cable attachment for swimming pool - cable connections are made safely inside housing of sign
Inventor: WALDMANN KURT
IPC: E04H4/14
Filed: 1973-12-22
Abstract: A warning sign also forming an anchorage for a cable for sectioning off a deep area of a swimming bath is designed so that there are no connections exposed in which children could trap their fingers. An L-shaped hollow member with a horizontal arm through which the cable passes, has a vertical arm with a plate at the bottom for anchor bolts for attachment to a suitable supporting surface. The warning notice is marked on the horizontal portion, and a closure plate over one end has a hole for insertion of an eye on the end of the cable. This eye engages a hooked rod which is tensioned by a nut housed in a compartment at the other end. This nut can be rotated from outside, and is retained between a partition inside and the end wall at that end.

Inventor: YANAGAWA YOSHIHIKO
IPC: G09G3/18
Filed: 1974-01-08
Abstract: The operating speed of an electronic timepiece, whose electro-optical indicator is excited by an oscillator with a frequency harmonically related to its stepping rate, is determined by an electrostatic sensor including a monitoring plate capacitively coupled to an electrode of the indicator. The output of the sensor is a bipolar pulse train developed across a resistor defining a differentiation circuit of small time constant with the condenser formed by the monitoring plate and the electrode, the capacitance of this condenser being on the order of 1 pf or less so that the controlling oscillator is not significantly loaded by the presence of the sensor.

Title: Non-return and anti-syphoning valve - in which return flow is prevented by pressure increase in outlet line
Inventor: BRAUKMANN HEINZ-WERNER
IPC: F16K15/06
Filed: 1974-03-28
Abstract: A de-airing arrangement is connected to the valve chamber with a circular elastic membrane connected to the valve housing outside the de-airing arrangement and mounted outside the inlet valve. A rigid ring shaped member is connected to the membrane and protrudes into the chamber and an elastic valve seat is mounted on a rim in the chamber to lie against the elastic valve seat to close the chamber. When the pressure in the inlet is sufficiently high, the rigid ring will lie hard against the valve seat. When the pressure further increases by a certain amount, both valves either side of the chamber will open downward and allow free flow of the liquid through the valve. If back pressure develops the upper valve will close against the rigid ring, so that the chamber is opened to atmosphere.

Title: Reduction of outside interference in language teaching - with damping or disconnection of connection between head-set and microphone
Inventor: RICKEN GUENTHER HEINZ
IPC: G09B5/04
Filed: 1974-05-15
