Title: Measuring transversely transported cut logs - detecting light reflected from logs and measuring time intervals between signals associated with leading and trailing edges
Inventor: SCHMID LUDWIG
IPC: G01B11/04
Filed: 1992-09-29
Abstract: In the log measurement method, pairs of light transmitters (4) arranged along a line essentially parallel to the longitudinal axis of the log illuminate the log (H) from either side of the measurement line. Light reflected from the log is received by an optical receiver (5) for each transmitter pair which produces a corresp. electrical signal. The logs are continuously moved transversely wrt. the measurement line during measurements. The receiver produces signals corresp. to intensity steps as log edges pass the reception region. Leading and trailing edge signals can be distinguished and the log dimensions derived from the intervening time periods and transport speed. ADVANTAGE - Operates without braking and accelerating large masses between measurements.

Title: Plastified sodium silicate putty
Inventor: GROSE-PERDEKAMP HEINZ-JUERGEN
IPC: C09J1/02
Filed: 1993-06-23
Abstract: The invention described in more detail below enables the scope of use of high temperature-resistant sodium silicate putties and adhesives to be broadened by providing for the addition, to the sodium silicate formulations, of organosilicon compounds having long-term temperature resistance which bring about, in the temperature range up to 350 DEG C, a plastifying effect. Above the temperature limit for these organosilicon compounds, the desired effect is superseded by the addition of inorganic substances with a softening action, so that the disadvantage of the brittleness of pure sodium silicate formulations can be compensated.

Inventor: STOLL KURT DIPL ING
IPC: F16B12/40
Filed: 1993-08-09
Abstract: The invention proposes a device (17) for connecting two profile parts (1, 2). The device has a first connecting part (18), which is arranged in a first anchorage groove (3) of the first profile part (1). A second connecting part (23) is provided for arrangement in a second anchorage groove (4) of the second profile part (2). The two connecting parts (18, 23) can be clamped together by means of a clamping part (24). Arranged between the two connecting parts (18, 23) is a supporting part (56), upon which the second connecting part (23) acts during the clamping movement of the clamping part (24). Due to said second connecting part acting on said supporting part, the supporting part (56) and the second connecting part (23) carry out a pivot movement relative to one another, which leads to the two parts (56, 23) being firmly clamped, such that they can be released, in the assigned second anchorage groove (4). The connecting device can be produced and handled in a simple manner and permits the profile parts to be connected without the removal of any material. <IMAGE>

Title: Process for regenerating and/or looking after wells, and apparatus for carrying out the process
Inventor: BLANK KARL-HEINZ
IPC: E03B3/15
Filed: 1993-09-25
Abstract: The invention is based on a process for regenerating and/or looking after wells, serving for obtaining water, with a low-level pump serving for water delivery.

In addition to the riser or pressure pipe already located in the well, the apparatus makes provision for the arrangement of a further pipe, which opens into the existing pipe at the upper end. In addition, a shut-off member is proposed, which is located downstream of the opening as seen in the flow direction of the water.

Title: Swimming pool with child safety covering
Inventor: KRUELL ANDREAS
IPC: E04H4/10
Filed: 1993-11-10
Abstract: Swimming pools are provided with a child safety means, in that the covering, comprising a covering sheet, is fitted such that it projects beyond the pool border and hangs down on the outer wall. Integrated into said covering sheet or in the border region thereof is a tensioning strap which is fitted with a safety clasp such that, after the tensioning strap has been tensioned, unintentional opening of the safety clasp is not possible. The border of the swimming pool is stabilized by a handrail or the like, with the result that it can reliably absorb the tensioning forces of the tensioning strap. Consequently, such a swimming pool is secured even if it is unsupervised over a period of some days, for example in a weekend house. After the covering sheet has been fitted and braced with the aid of a tensioning strap, a child of up to six years old can walk on the covering sheet without there being any risk of drowning or the like. The same applies for small animals. <IMAGE>

Title: Drive for road vehicles using an electromagnetic travelling field (linear motor)
Inventor: JACOBS BERND
IPC: B60K6/48
Filed: 1994-02-24
Abstract: Today, individual road traffic uses gigantic amounts of fossil fuels with the known unfavourable consequences for the atmosphere. The operation of non-trackbound, individually used road vehicles using electrical batteries is limited in terms of the restricted energy capacity. The electrical operation of individual road vehicles with sufficient electrical power would at the moment only be possible by means of a costly overhead line system. The solution of the problem would be to operate electric vehicles which draw their energy inductively from an electromagnetic travelling field which is let in, invisibly, into the roadway. This energy would be particularly environmentally friendly if it were produced by alternative means (wind, sun, hydrogen technology). The method for driving road vehicles using an electromagnetic travelling field would produce individual road traffic which is not trackbound or dependent on overhead line and has a satisfactory supply of energy for locomotion.

Title: Mixer tap for water
Inventor: GNAUERT WERNER
IPC: E03C1/04
Filed: 1994-03-19
Abstract: The mixer tap has the thermostatic valve element (3) pressed onto a valve seat (4) by a spring. The larger outer face of the valve element is subjected to the cold input pressure while the smaller rear face is subjected to the mixed flow pressure. If the pressure difference exceeds a set level the valve element lifts and increases the control gaps for the valve, i.e. the relative mixer rates are retained. The cold water face of the control valve is 10 to 15% larger than the mixed water face and the valve starts to lift from one bar pressure difference. The control valve is sealed into the bore by O-rings.
