Abstract: A speech valve for placing and fitting on a tracheostomy cannula, having a throughflow body enclosing a throughflow channel which on one side at one end has a connection for joining to a proximal end of the tracheostomy cannula, a one-way valve located at an end of the throughflow body opposite the connection, and, at a distance along the throughflow channel between the connection and the one-way valve, a valve opening is located which is closable by an overpressure valve. The overpressure valve arrangement has at least one elastically deformable valve flap which, in a first state covers the valve opening provided between the connection structure and the one-way valve on the throughflow body and, at a predefinable overpressure occurring inside the throughflow channel converts, by an overpressure-driven elastic deformation of the valve flap, to a second state, in which it at least partially exposes the valve opening.

Abstract: The present invention relates to a food packaging comprising a first par-tial shell, which has a first depression and a first flange delimiting said first depression; a second partial shell, which has a second depression and a second flange delimiting said second depression; the first and second partial shells being coupled to each other via their flanges thus defining a cavity for holding food. The invention relates to novel types of packaging and partial shells. The first partial shell can be made of a material that is different from that of the second partial shell. The partial shell can have a window that consists of a first material which is different from a second material that forms at least one outer surface of the partial shell. The flange can have a first region that consists of a first material and a second region that consists of a second material.

Abstract: The present invention refers to a method and a machine for packaging a food product by means of foil-type half-shells, wherein the foil-type half-shells are trimmed before being loaded with the food product, the trimming unit for trimming foil-type half-shells being located outside a food processing unit in which food products are loaded into foil-type half-shells.

Abstract: The present invention relates to a method and a device for folding a foil material half-shell edge which protrudes from a surface of the packaging of a packaged food product, said half-shells receiving the food product. The half-shells have flanges, at least some regions of which lie one on top of the other and which form the protruding edge. The aim of the invention is to improve a quick and reliable method which can be carried out with little effort for improving the appearance of food products packaged in foil half-shells. This is achieved in that during a relative movement between a packaged food product and a die, an edge region of the die presses against the protruding edge of the foils, whereby the edge of the foils is at least partly folded to lie substantially flush on one of the half-shells. The invention further relates to a device which corresponds to the method.

The invention also relates to a corresponding method.

Abstract: The invention relates to a method for manufacturing packaging for a food product, in particular a hollow shaped chocolate article. In the disclosed method, two half-shells are provided, each of which includes a pre-shaped, curved thin foil having an edge that projects peripherally, a food product is introduced between the half-shells, the edges of the half-shells are coupled to one another such that the two half-shells accommodate the product in a cavity, a sealing layer being provided in at least some sections between the edges, and the edges are joined to one another using a sealing and folding process. In order to be able to carry out said method as easily and conveniently as possible, effectively seal the half-shells at the edges and obtain packaging that is esthetically appealing from the outside, the sealing process is performed at the same time as the edges are folded or after the edges have been folded.

Abstract: A method for homogenizing the static magnetic field with a distribution B0(r) in the active volume of a magnetic resonance apparatus having a number N of shim coils defines a target field distribution B0T(r) using a filter method in which a norm of the shim currents is influenced by means of filter factors. An optimization procedure works in a parameter space having M control parameters, wherein 2?M<N. One of the control parameters is used as a weighting parameter for modification of a spatial weighting function and another control parameter is used to control the filter factors. Using this method the hardware limitations can be taken into account when determining the target field distribution, without a significant increase in the computational effort to determine the target field distribution during optimization.

Abstract: In a coil arrangement for nuclear magnetic resonance comprising a main coil (13), a shielding coil (14), and at least one correction coil (41), the function of which consists in forming a magnetic field gradient with eddy current properties which are as good as possible, the main coil (13) and the shielding coil (14) are electrically connected in series with the correction coil (41). The deviations of the residual field from the desired design generated by production tolerances are thereby modified by the correction coil in such a fashion that the long-lasting eddy currents are suppressed. This either reduces the waiting time that must lapse after a gradient pulse before a predetermined field homogeneity is achieved or e.g. the deviations from the desired field are minimized in imaging applications.
