Title: Cheap golf tee which rots away quickly after use - consists of a moulded, extruded mixt. of cellulose material, acrylic ester resin and vinyl acetate resin
Inventor: CHOI WON YONG
IPC: A63B57/10
Filed: 1993-08-10
Abstract: A golf tee (I) comprises a mixt. of 75-94 wt.% cellulose material (II), 1-20 wt.% acrylate ester (III) and 1-20 wt.% vinyl acetate (IV). Also claimed is the prodn. of (I) by making a mixt. of 75-94 wt.% (II), 2-20 (pref. 2-13) wt.% (III) and 2-20 (pref. 2-13) wt.% (IV), stirring the mixt. with water, drying the stirred mixt. at 100-250 (pref. 200) deg.C to remove most of the water, and extruding the dried mixt. The mixt. contains 2-11 wt.% (III) and 2-13 wt.% (IV); pref. mixt. contains 83 wt.% (II), 4% (III) and 13% (IV). ADVANTAGE - (I) can be cheaply mass produced.

Title: Method and device for positive disconnection of hand-operated working equipment
Inventor: BOLAY CHRISTOPH DIPL ING
IPC: B23B47/24
Filed: 1993-10-13
Abstract: The invention relates to a method and the corresponding device for positive disconnection of hand-operated working equipment in working situations, such as a rotating tool tilting, being stalled or being destroyed. The working equipment removes the material abrasively from the workpiece and engages with the workpiece in a positively locking or force-fitting manner. The solution according to the invention is intended to provide disconnection reliably and at a low cost in order to reduce the danger to the operator in emergency situations. In this case, the vibration (oscillation) acceleration of the working equipment is measured and the function a(t) in a predetermined time interval (T) of constant size is determined from the individual measured values. Subsequently, a comparison is carried out to determine whether this function a(t) has no zero crossing within this time interval (T). If none of the function values within the time interval (T) correspond to the zero crossing, a disconnection signal is generated and the working equipment is disconnected.

Patent DE-4435870-A1 (DE)
Inventor: ECKER FELIX
IPC: F15B13/04
Filed: 1994-10-07
Abstract: The valve has a valve piston (2) movable in a housing (1), which locks in the closed position, together with an elastic sealing ring (14) fitted in a groove in the housing (1) between an inlet (10) and a feed (12) for the pressure medium and, in the open position, bridges the sealing ring (14) with a line consisting of recesses (17) extending axially parallel from the periphery of the valve piston (2). Thus, in the open position, the sealing ring is exposed to the flow of the liquid pressure medium. That has so far been avoided. According to the invention, the sealing ring is, however, held in its seat in the housing groove by the full peripheral sections of the valve piston remaining between the recesses. In addition, the direction of travel of the valve piston (2) to the closed position is opposed to the direction of flow from the inlet (10) to the feed (12). The shifting of the line to the surface of the valve piston in the form of the axially parallel extending recesses simplifies production and makes it possible to reduce the cross-section of the valve piston and hence that of the entire valve.

Title: Ballast for connecting a discharge lamp
Inventor: PRILLER R
IPC: H05B41/298
Filed: 1981-04-14
Abstract: Discharge lamps are often connected to the AC network through an inverter and a rectifier, the inverter operating at a frequence of at least 10 kHz. It is possible in this way to maintain the necessary inductance for limiting the low current and at the same time to obtain a high lighting efficiency. However, with this system, the shape of the current extracted from the network differs very much from the sinusoidal shape. In order to avoid this disadvantage the extraction of current has already been controlled by means of a two-state rectifier receiving the half-wave of the network as an order value and the lamp current has an effective value. With this ballast the resulting modulation of the lamp voltage with the network voltage is avoided.
