Abstract:
A method for determining a triggering time for the issuance of an alarm by an alarm device. A measured value is sensed at a measuring time, and the measured value is indicative of a hazard potential within a monitoring range. A waiting time is identified by way of a function which respectively indicates an assigned waiting time for a plurality of different measured values and which has a continuous profile. The triggering time is determined on the basis of the measuring time and the identified waiting time. In addition, an alarm device having a detection device for sensing a measured value and having an evaluation device which is configured to carry out said method is described. In addition, a program element for determining a triggering time for the issuance of an alarm by an alarm device is described, wherein the program element can be loaded into an evaluation unit of the alarm device and can cause the abovementioned method to be carried out.
Abstract:
A method and apparatus for selectively transporting one of animal feed and cleaning products from a source via a feed line to a removal location is made possible by selectively feeding in a pulsed manner a gaseous medium.
Abstract:
A probe carrying vehicle is described which has at least one probe carrier which preferably carries at least one eddy current probe and at least one magnetic field probe for ground and foreign matter detection in a search area. Spacing means which may be in the form of a bogie assembly with wheels or chains or the like are provided to maintain a spacing between the ground and the probes. The probe carrier is movable over the search area by means of a craft, to which the probe carrier is flexibly coupled by means of coupling means. The coupling means are disposed on one end of a preferably long pole, the other end of the pole being fixed rigidly to the probe carrier. The pole ensures a proper orientation of the probe relative to the ground particularly on uneven ground.

Abstract:
A device for supplying farm animals with a liquid feed from an automatic feeding device comprises a flexible feed discharge line connected to the feed device and terminating in an animal operated discharge member or sucker. The sucker is supported by a member which is moved back and forth on a conveyor in the form of an overhead trolley. The liquid feed connecting line which connects the feeder is flexible and it is moved over a support which is advantageously on a level substantially equal to that of the feeder so that the connecting line is supported as the end thereof carrying the sucker is moved by the overlying conveyor. Because the sucker may be displaced into a plurality of different feeding stations in a controlled manner, feed can be supplied in a controlled manner and accurately metered in accordance with the feed to be given out at each station.
Abstract:
A test device, for checking the functioning capability of a gas-alarm annunciator, has a reservoir in which are located a target fluid and a carrier fluid. At least a part of the carrier fluid is present in a liquid aggregate state and the target fluid is at least partially dissolved in the liquid carrier fluid. An extraction device engages into the reservoir such that the target fluid can be extracted along with the liquid carrier fluid. The target fluid is constituted such that on reaching a coverage area of a properly functioning gas-alarm annunciator it will cause the gas-alarm annunciator to annunciate an alarm. A test system and a test method for checking a gas-alarm annunciator's functioning capability use such a test device.
Abstract:
A method for determining a quantity of liquid food which has been drunk by animals, in particular water or milk from a drinking dish (2), the liquid food being fed into the latter, characterized in that a preselected, determinable quantity of liquid food is fed into the drinking dish (2) and, after the food has been removed by an animal, the quantity of liquid food which has actually been drunk is ascertained exactly by means of a filling-level measurement, by means of a filling-level-measuring device (7), on an individual animal basis after drinking has taken place, and the preselected, determined quantity of liquid food is fed in via a reservoir (14), which is connected to the drinking dish (2) via at least one connecting conduit (13), and a filling level, an ascertaining of a residual quantity and/or a speed of removal of the food from the drinking dish (2) is ascertained, regulated and/or controlled there.
Abstract:
The invention relates to a device for verifying the state, especially the state of health, of mammals, especially agricultural working animals, which suckle from a teat. Run-out sensors for determining values, such as resistivity measurements, temperature values of the animal and/or the foodstuff, pH determination, gas measurements from the pharynx and stomach, are allocated to the teat.
Abstract:
A device for the controlled supply of animal feed includes a supply container, a feed trough with a side wall having an inlet, a conveying device with a drive unit connected between the supply container and the inlet of the feed trough, whereby the conveying device has an outlet opening that is coaxially arranged relative to the axis of the conveying device and the outlet opening is directly connected to the inlet of the feed trough. A control unit is connected to the drive unit for switching on and off the drive unit. A control flap is pivotably connected above the inlet and includes a control element that is connected to the control unit. The control flap activates the control unit for switching on and off the drive unit depending on the amount of animal feed present in the feed trough behind the control flap or due to activation by an animal to be fed. This device ensures that an animal to be fed only receives its allotted amount of animal feed because only after emptying the feed trough a new feed distribution is possible.
Abstract:
Reactive gases like, for example reducing gases, specifically carbon monoxide, are detected in a gas mixture, particularly in air, with extremely high sensitivity and with high precision using a gas detector in which the attenuation of the intensity of an infrared radiation beam by a catalyst layer is utilized. Such catalyst layer contains at least one transition metal selected from at least one of the groups I, VII, and VIII of the Periodic Table of the Chemical Elements. Preferably, chemical elements are used having an atomic weight in the range of about 100 to about 205. The detection of carbon monoxide is particularly sensitive using a catalyst layer which substantially contains a metal capable of forming a carboncarbonyl compound with carbon monoxide. The sensitivity and precisionof detecting carbon monoxide and other reducing gases can be significantly increased by periodically exchanging the gas mixture to be investigated in a measuring chamber and replacing it with a pure reference gas from a reference chamber. The sensitivity and precision of the gas detection can be further increased by periodically alternating the temperature of the catalyst layer during such period of gas exchange. The alternating signal this obtained at an output of the gas detector can be evaluated for determining the concentration of the reactive or reducing gases in the investigated gas mixture.
