Title: Loop attachment to ski stick - secures stick to glove of user and releases above certain force
Inventor: ROSSDEUTSCHER GUENTHER
IPC: A63C11/22
Filed: 1990-02-19
Abstract: The handle of a ski stick has a releasable loop (14) attached to one end of a holder whose other end is attachable to a catch which can be removed from the head of the grip.  At least the upper side of the grip head is open. The loop is attached to the holder with a second catch. Both catches are held by elastic resistance.

Title: Water heating system control - includes mixing valve in circuit directly connected to boiler allowing priority heating of domestic water
Inventor: TAAG JUERGEN
IPC: F24D19/10
Filed: 1990-05-11
Abstract: The method of controlling a water heating system ensures that the heating of domestic water takes precedence over the heating of the two circuits.

When the water temp. has reached the required level, or a min.  time lapse has expired, the mixing valve is opened and the heating circuits are allowed to heat up. USE/ADVANTAGE - The medium temp. range of the  boiler flow is reduced and the heat loss minimised.

IPC: A61B5/352
Filed: 1990-09-22
Abstract: A method and a device for measuring the heart function are described. In this method, the pressure and the volume of the left ventricle are measured. From these values, the product is formed as a function of time.

Title: Adjustment of tension of strings in tennis racket - is performed by rotary knob at end of handle, controlling tightness of wire through string loops
IPC: A63B51/12
Filed: 1991-01-04
Abstract: A tensioning wire (30) pref. of steel is threaded through the loops between sections of string and over guidance rollers. Tightening of the wire (30) pulls the loops radially outward, increasing the tension in the strings. The tension is measured and displayed digitally by a device (20) installed between the ends of the wire (30) and the stretching element which is pulled into the handle by rotation of the knob. The peak value of the tension is calculated, stored and displayed. An electromechanical force transducer is arranged between the tensioning device and strings. The transducer is a strain gauge. The successive tension peak values are electronically counted. The tension measuring device further comprises a transmission for wireless data transmission to a receiver in a remotely located display device. ADVANTAGE - Tension can be varied easily and quickly even during match, with significant changes achieved by comparatively little repositioning of connection loops.
