Inventor: PICKEL NORBERT
IPC: G01N33/52
Filed: 1980-11-28
Abstract: Reagents are manufactured in a new way for use during the process of cleaning toilets so as to enable early detection of illness as a result of their reaction with urine. The use of the reagents with the disinfectants used in cleaning toilets is simplified and expanded without additional costs. The reagents are used during cleaning and the illnesses are indicated by colouration caused when they react with the urine. The reagents are combined with a disinfectant and may be applied in a cleaning container as well as directly into the toilet. The reagents react to different illnesses and are replaced after two to four weeks. They may be applied in the form of tablets or sprays.

Title: Flexible moisture relief roof strip underside coating - has elastic perforated outside layer for all round pressure relief
Inventor: RUEHL KARL DIPL CHEM DR
IPC: E04D5/10
Filed: 1980-12-12
Abstract: As used esp. for covering roof structures subjected to moisture, a length of roofing material consists of a sealing length with a coating of flexible porous vapour-expansion material on its underside. This coating (2), at least 2 mm. thick, is provided with an elastic perforated outside layer (3). The two may be perforated at equal intervals. The outside layer can be a highly elastic foil sheet, while the vapour relief layer is of loose textile or similar, or of open-celled foam material, or a fibre strip layer. Using the simple cold-cementing laying process, this permits relief of moisture or air pressure on all sides, and prevents thermal or mechanical tension in the length of material.

Title: Cigarette filter with impermeable wrapping - has troughs in wrapping running continuously from end to end
Inventor: BOROWSKI HORST
IPC: A24D3/04
Filed: 1980-12-23
Abstract: The cigarette filter comprises a filter core placed directly on a wrapped strip of tobacco, and contained in an impermeable wrapping in which there are flow troughs extending for part of the length from one of the ends. The wrapping is enclosed by mouthpiece paper having a narrow peripheral zone made permeable to air by apertures, clear of the joint between the mouthpiece paper and the tobacco. The troughs (3) run continuously from the mouthpiece end of the wrapping (2) to the tobacco end, and their diameter and that of the apertures (5) gives a flow resistance in them and in the tobacco and filter core such that the smoke passes only through the core (1) and the air only through the apertures, no mixture of air and smoke being formed in either.
Patent DE-3049239-A1 (DE)
Inventor: GRILLENBERGER TRAUGOTT DIPL IN
IPC: G21D3/04
Filed: 1980-12-27
Abstract: The conical valve body (2) is seated on a hollow main piston (4) which is movable in a cylinder guide (8) of the valve housing (1). A closing spring (23) is arranged in the piston interior (9) loadable by the medium to be switched. The valve cone (2) has throughflow channels (11, 12) which bypass the valve seat (3) from the inlet connection (21) to the outlet connection (22) in the manner of a free-flow valve. These can be shut off by a further valve body (15) which is connected to a further piston (19) displaceable in the cavity of the main piston (4). The valve is closed in steps, in that the throughflow channels (11, 12) still remain open when the valve cone (2) has reached the valve seat (3) as a result of an increase in pressure in the piston interior (9), until, as a result of a further pressure increase, the valve body (15) too is actuated by the further piston (19). The pressure rise in the medium to be switched and the load on the pipelines are thereby reduced during the closing operation. <IMAGE>

Patent DE-3108470-A1 (DE)
Title: Method for controlling the supply and removal of energy, and use of the method
IPC: G05D23/19
Filed: 1981-03-06
Abstract: A method is proposed for the time-and energy-optimal control of the supply and removal of energy for heating up or cooling down a material phase. Taking account of the fact that it must hold to a first approximation that:   - the energy (v(n)) absorbed or dissipated per time unit by the material phase at an instant is proportional to the energy difference ( DELTA T(n)) between the material phase and the heating or cooling members; - this energy difference ( DELTA T(n)) present at an instant is inversely proportional to the energy (v(n-1)) previously absorbed per time unit a system of equations for determining the furnace control steps (TH) is evaluated working backwards from measurements of the phase-specific capacity for the supply or dissipation of energy at the start of the method (T(o), v(o), TH(o)) and a stipulation of the phase end temperature (Tm(n)) to be achieved, as well as from the furnace temperature (TH(n)) then to be set. The furnace is driven in accordance with this using the staircase characteristic obtained. In order to refine the method, when carrying out the control the behaviour of the material phase can be further observed in order continuously to adapt the still remaining controlled variables from deviations which arise with respect to the computed characteristic. <IMAGE>

Title: Compressed-air pile driver
Inventor: ZINCK EUGEN
IPC: E02D7/10
Filed: 1981-03-28
Abstract: The invention relates to a compressed-air pile driver with a pile hammer which divides the housing interior into a top and a bottom compression space which can be alternately connected to a compressed-air source via air-supply connections and a control valve and each have an exhaust-air opening opened alternately by the pile hammer. In order to reduce the air consumption of the compressed-air pile driver and obtain an increased impact capacity, a pressure space is divided off in the top compression space by means of a wall parallel to the end face of the pile hammer. The air-supply connection of the top compression space leads into this pressure space. An air-intake opening arranged in the wall for the top compression space is closed by the pile hammer in its top initial position, the pile hammer being held in place in its top initial position by a holding arrangement. The pile hammer is thrown downwards explosively only when a pressure overcoming the adhesion has built up in the air-intake opening, a high impact force being achieved over a short distance.

Title: Thrust measuring device, in particular for drive units of underwater vehicles
Inventor: KARPOWSKI SIEGFRIED ING GRAD
IPC: B63G8/16
Filed: 1981-07-28
Abstract: The invention relates to a thrust measuring device for drive units of underwater vehicles for precisely controlling the power units. The thrust measuring devices are connected to the control of the power units via an evaluation device. The power units of the drive unit are mounted on one side to parts of the structure frame of the unit in such a way that when the power units are running these parts are acted upon by bending or rotating. The bending or rotating is dependent on the thrust of the power unit and can be determined by strain gauges. As a second possibility, hinge-like mounting elements for the power units are described between whose parts pressure measuring sensors, for example piezo crystals, are arranged, the measured pressure being a measure of the thrust of the power units. <IMAGE>
