Patent DE-3347151-A1 (DE)
Title: Mordanting treatment and alkali treatment for wood
IPC: B27K5/02
Filed: 1983-12-27
Abstract: Antique hues on oak furniture can be achieved inter alia by the action of caustic potash or caustic soda solutions. These methods entail the following disadvantages: Immediately after the alkali treatment, or after a short exposure time (up to 10 minutes), it is attempted to remove the unconsumed, remaining alkali solution from the wood, which is very labour-intensive and requires large amounts of water. This is only partly successful. Due to their bleaching power, remains of alkali solution cause the hue to brighten sooner or later, depending on the quantity. This causes problems for the customer and the manufacturer, for example if a dresser is ordered 1-2 years after a cupboard has been delivered. Moreover, the alkali solution which has been rinsed off represents an unnecessary pollutant for the environment. The solution of these problems can be found essentially in the patent claim. Novel aspects compared with other processes are:   The highly-concentrated alkali solution, which should be at least 20%.   The short, economically acceptable immersion period. The complete utilisation of the reaction between alkali solution and tannins by allowing exposure until drying takes place. The remainder of the alkali solution is converted into harmless salts by neutralisation by means of dilute acids, using the immersion method. The effectiveness of the acid solution can be measured with the aid of indicator paper which is placed on the object which has been immersed for the second time and then dried, whereupon the indicator paper is sprinkled with distilled water, and, if necessary, the activity of the acid solution can then be corrected.

Title: Safety dog lead with rapid long-range opening
Inventor: SIEBERG ARNOLD
IPC: A01K27/00
Filed: 1984-03-09
Abstract: The safety dog lead is a dog lead which simplifies use and increases the safety of the dog walker. The conventional releasing of the lead by bending down to the animal and opening the snap link is eliminated. If the dog is walking on the lead, a bolt which is under spring pressure closes a receiving device which is attached to the dog's collar. The bolt can be retracted by finger tension exerted via a cable from the hand loop, so that the animal (dog) is immediately free. The safety of the dog walker is substantially increased by this simple and rapid releasing of the dog.

Patent DE-3420814-A1 (DE)
Title: Local communications system with a star-type network
Inventor: KREUTZER HEINRICH W DIPL ING
IPC: H04Q11/04
Filed: 1984-05-30
Abstract: Local communications systems exist for different services. In PBX systems, >>telephony<< is of prime concern. Distributed processors communicate via data buses. The problem of implementing or including broadband services and the use of optical telecommunications at least in parts of such a system is still essentially unresolved. A local communications system according to the invention is designed for optical and/or electrical channels and offers enough flexibility to meet most of the sector-specific requirements for individual services but nevertheless to develop the integration of services. The components located between the subscriber stations are essentially passive. The network is designed with a star structure. Narrow and medium-band traffic is handled in a fully synchronous time division multiplex system with random access and high-speed circuit switching. In an intrinsically separate transportation of broadband services, their signalling is carried out as for narrowband services. Unauthorised access to time slots can be prevented through additional measures. <IMAGE>

Patent DE-3434815-A1 (DE)
Title: Key locking unit
Inventor: TOBIESEN KARL HEINZ
IPC: E05B19/00
Filed: 1984-09-22
Abstract: The key locking unit is intended to be used especially to reduce the incidence of driving while under the influence of alcohol while the consumer of alcohol is still able to reason coherently. It is all too frequently the case that rules of behaviour are not followed any more when fairly large quantities of alcohol have been consumed. Evidence of this is provided by the fact that 220,000 people lose their driving licences each year in the Federal Republic of Germany because of alcohol. By means of the key locking unit, the driver can make the car key unusable for the length of time he desires or for the time it takes for the body to break down the alcohol. This is achieved by setting a period using the time regulating system built into the unit, placing or pushing the key into the unit and locking the key for the set period by means of the locking system which depends on the time regulating system.
Patent DE-3435811-A1 (DE)
Title: Labyrinth seal
Inventor: TORNARE JEAN
IPC: F16J15/44
Filed: 1984-09-28
Abstract: The special feature of the labyrinth seal is axially displaceable concomitantly rotating sealing rings (4) which are sealed relative to the shaft or sleeve (1) by means of a cup packing (5). As a result, the concomitantly rotating sealing rings can adjust themselves automatically in the annular gap. However, this would mean that they would be pushed to one side of the gap by the positive pressure, something which is, of course, to be avoided. This is achieved by the fact that chambers (43) are machined out of the low-pressure sealing surface, being connected via holes (44) to the positive pressure side. The medium to be sealed off therefore passes through these holes into the chambers and a centrifugal effect builds up a pressure which counteracts the positive pressure, with the result that the rings (4) float in the annular gap. <IMAGE>

Title: Method and device for determining the wall thickness and/or the speed of sound of test specimens with ultrasonic pulses
Inventor: KLEINERT WOLF-DIETRICH
IPC: G01H5/00
Filed: 1984-11-16
Abstract: The invention relates to a method for determining the wall thickness and/or the speed of sound of test specimens with ultrasonic pulses. For this purpose, the propagation time, tw, of the corresponding ultrasonic pulses between the sound input face of the test specimen (7) and the rear wall of the test specimen lying opposite the sound input face is determined with the aid of a first transmission and reception transducer (601). With the aid of a respective additional transmission and reception transducer (600 and 602) which are arranged symmetrically with respect to the first transducer (601), that propagation time, ts, is determined which is required by the ultrasonic pulses to pass from the transmission transducer (600) via the reflection area (701) of the rear wall (700), at which area the sound radiation of the first transmission and reception transducer (601) is reflected, to the reception transducer (602). The wall thickness and/or the speed of sound of the test specimen (7) is then calculated from the propagated time values tw and ts and the distance, a, between the additional transmission transducer (600) and the additional reception transducer (602). <IMAGE>
