Patent DE-3639843-A1 (DE)
Title: Construction material, process for the production thereof and use thereof
Inventor: WIRSCHING FRANZ DIPL CHEM DR
IPC: C04B28/22
Filed: 1986-11-21
Abstract: A construction material consists of a set and/or puzzolanically hardened mixture containing 5 to 30% by weight of sulphite-containing flue-gas desulphurisation product from dry and/or quasi-dry processes, 70 to 95% of fly ash, if appropriate additionally up to 15% by weight, based on the mixture, of a hardening agent and, if desired, additionally up to 3% by weight of further additives and auxiliaries. It is preferably used in the form of subsequently ground briquettes, pellets, mechanically compacted blocks, extruded material or cast pasty compositions.

Patent DE-3640696-A1 (DE)
Title: Round-bale press
Inventor: HEUVEL J J V D
IPC: A01F15/14
Filed: 1986-11-28
Abstract: The invention relates to a round-bale press with a tying device for tying each round bale into a twine-like or band-like tying means, with a tying-means store, from which the tying means runs to a movable tying member and to the round bale, and with a severing device for the tying means. In known round-bale presses, the press driver has no possibility of monitoring the tying operation. Faults in the tying operation are either detected too late on the ejected round bale or lead to damage in the round-bale press. According to the invention, provision is made for arranging between the stock of tying means and the round bale a detector, actuable by the tying means itself, for determining the movement and/or tension of the tying means, the said detector being in signal-transmitting connection with at least one indicator. The press driver is thereby constantly informed of the proper progress of the tying operation and can intervene immediately if a fault occurs in the tying operation.
Patent DE-3642690-A1 (DE)
Title: Device for a spinning machine for the monitoring of two individual threads of a double thread combined from these
Inventor: GUETTLER HERMANN DIPL ING
IPC: D01H13/16
Filed: 1986-12-13
Abstract: Device for a spinning machine for the monitoring of two individual threads of a double thread combined from these. In known devices for the monitoring of two individual threads, there is the possibility that, when short-staple fibre material is used, in the event of a break of an individual thread the remaining individual thread is not sufficiently deflected and therefore this individual thread is not broken. Inter alia, this is to be prevented reliably. In the device according to the invention for the monitoring of two individual threads, a pivoting body is coupled to a mass element. The latter is arranged at a distance from the pivot axis and is movable relative to the pivoting body. Even under only slight deflections, the pivoting body commences a pivoting movement, so that the remaining individual thread is reliably broken. The device described can be used on spinning machines which work by the so-called Siro-Spun< TM > process.
Patent DE-3707012-A1 (DE)
Title: Arrangement for connecting electrical components to contact surfaces of a contact pattern on a circuit carrier, especially for an electronic data input keyboard
Inventor: SPRANGER DIETER
IPC: H01H13/70
Filed: 1987-03-05
Abstract: In the case of matrix keyboards, in the case of which the keys are arranged with direct electrical contacts in each case at the intersections of conductors, a diode is arranged in series with each key contact, in order to make possible an N-key rollover. In the case of some technical implementations of the key contacts, for example in the form of electrically conductive materials which are applied onto plastic films by screen printing, the series connection of diodes to each contact element is not directly possible. This is made possible according to the invention by a fixed carrier board (6) for the circuit carrier (7), which can be clamped to a clamping plate (10) in such a manner that the diodes (8) which are arranged in chambers (9) in the clamping plates (10) can reliably be pressed against the contact surfaces (13, 14) of the flat circuit carrier (7). In this way, those elements which are used to decouple the individual keys can be fitted reliably and without damaging the plastic film, and this measure also results in a particularly cost-effective production process. <IMAGE>

Title: Method for improving the discharge technique for liquid manure used for agricultural purposes
Inventor: HEINZE GERALD DR
IPC: C05F3/00
Filed: 1987-07-29
Abstract: The invention relates to a method for improving the discharge technique for liquid manure used for agricultural purposes, by employing organic fibres from refuse and waste utilisation. Organic fibres are porous and therefore absorb the liquid manure. The two materials, namely the organic fibre and the liquid manure, are agglomerated according to a particular embodiment of the invention. The liquid manure bound to the organic fibre can be discharged onto the fields by means of the conventional agricultural appliances in the same way as a solid manure. A further advantage is afforded in that the organic fibre exercises an odour-binding effect on the liquid manure. This discharge technique according to the invention offers a series of advantages which relieve the environment, for example a reduction in odour, no dissipation of nitrate into the groundwater, longer-lasting binding of nutrients, etc.

Title: Demountable formwork and process for introducing corrosion-protection material into the interspaces between the ropes of a rope cable of roof or bridge structures in use
Inventor: VOGELER KARL REINER
IPC: E04G21/12
Filed: 1987-10-31
Abstract: Demountable formwork for introducing corrosion-protection material into the interspaces between the ropes of a rope cable of roof or bridge structures in use. The subsequent introduction of a corrosion-preventing material into the interspaces of rope cables necessitates an outer formwork. In a known process, the cable is provided with a sheathing which can be removed again after the introduction and hardening of the corrosion-protection material. This sheathing is complicated and expensive, because, to remove it, it subsequently has to be cut open and, furthermore, can be reused elsewhere as formwork at most under identical conditions, but not in any way desired. The new formwork is to be easily mountable and demountable and is to be capable of versatile and multiple use. The formwork is produced in the form of rigid profiles of sufficient length and of an appropriate cross-sectional shape which are held in the necessary position by means of tenter frames and/or tightening straps and which can be provided with an elastic plastic layer on the side facing the ropes. Use in corrosion-protection measures in rope cables of roof and bridge structures.

Title: Hand-held unit with oscillating tool movement
Inventor: BERNER GERD DIPL ING
IPC: B24B23/04
Filed: 1988-02-25
Abstract: Vibratory grinders in an external form known from the angle grinder occasionally exhibit uneven stress on the abrasive medium and have hitherto been obtainable only as independent powered hand tools. A new kinematic arrangement is intended to make the removal of abrasive medium uniform. As an attachment for commercially available angle grinders, it is intended here to enable the conversion to the vibratory grinder. With a supporting element (3) to be fixed to the housing of an angle grinder, and an excentric (2) to be fixed on the output shaft of the angle grinder, and also at least one flexible intermediate element (4, 104) which is arranged asymmetrically to a plane (12) in which the axis (7) of the output spindle (1) runs, the inexpensive conversion of an angle grinder to a vibratory grinder is possible, the latter being notable for more uniform removal of the abrasive medium. Useable, for example, for grinding work, in particular in poorly accessible places. <IMAGE>

Title: Spray can for sprayable liquids
Inventor: MUEHLBAUER JOHANN
IPC: B05B9/08
Filed: 1988-03-23
Abstract: The purpose of the invention is to avoid the use of pressurised propellants for spraying liquids so as to avoid risk to the environment and harming the ozone layer. Accordingly, the spray can according to the invention is provided with a receiving chamber, which can be refilled as many times as desired, for the liquids to be sprayed and with a propellant-free, electric spray drive. The housing (1) of the elongate spray can is divided into a front compartment (4) with the spray head (11), the spray-head mechanism (12) and a potentiometer (13), a central compartment (5) for receiving the spraying liquid and a rear compartment (6) with the electric driving part, the power supply, an electric pump (7) and an electronic mechanism (8). The spray head (11) can be depressed counter to spring force and, as a result, opens a path for the spraying liquid. The depth of depression at the same time controls the output of the pump (5). The closable filling hole (21) makes it easier to refill with spraying liquid. A battery or an accumulator may be used to supply the electronic mechanism (8) and the pump (7) with power. Spraying procedures can hence be carried out as often as desired without any adverse effect on the environment. <IMAGE>
