Patent EP-0261366-A1 (EP)
Inventor: LODAHL MANFRED DIPL-ING
IPC: H03F3/217
Filed: 1987-08-07
Abstract: A switched-mode amplifier is described, which is suitable in particular for use as a digital power amplifier for the output stage of an AM broadcasting transmitter. Partial voltage sources are connected in series so that a switchable variable DC output voltage can be produced, which corresponds, for example, to an AF signal which is to be amplified. At least one of the partial voltage sources contains a group of switches, which may advantageously consist of several semiconductor (power) switches connected in parallel. The interfering dissipated power resulting from the switching operations can thus be distributed over the semiconductor switches so that they are not destroyed. The commutating currents produced by the freewheeling diodes are limited by peak current limiters. <IMAGE>

Abstract: The pressure applying device is for pressing surface coating material onto a supporting material pre-milled with respect to shape and is equipped with a number of spring-loaded pressing rollers (1), which are arranged respectively offset one behind the other in the direction of continuous operation, act in staggered fashion on the surface material and continuously press the said material against the pre-milled shape of the supporting material. In order to further develop such a device in such a way that as many different edge or profile shapes as possible can be worked with one and the same pressure applying device, i.e. without set-up times, the pressing rollers (1) are designed or suspended in such a way that they are movable within limits with respect to the supporting material both in the direction of pressing and in the axial direction. <IMAGE>

Filed: 1987-12-07
Abstract: A scanning differential phase contrast microscope is described in which an objective system (20) focusses the radiation from a radiation source (10) to a preferably diffraction-limited spot (A) in an object plane (30). The diffraction-limited spot is imaged on two point detectors (63+61 and 64+62)  via  an imaging system (40) and a beam divider (60). By using this confocal principle, a differential phase contrast microscope is obtained having a low sensitivity to details which are out of focus, an increased resolution in the object plane and little crosstalk between the two detectors.

Title: A means for training golf swings
Inventor: LARSSON KURT
IPC: A63B69/00
Filed: 1987-04-02
Abstract: A means for training golf swings. It is desirable when training golf strokes to be able to practice without having to visit a golf course or training range, or having to have considerable space. This desire has been satisfied by attaching an air ball (7) by means of a cord (6) to an attachment device (5) secured to a post (3) where, after being teed off, the ball describes a circular trajectory around the post 3. The golfer can hit an air ball (7) with full force and then replace it on the tee ready for the next stroke, without having to move. The device takes up an area of about 0.5 m2.

Title: Food container and method of manufacturing.
Inventor: WENDT DAN J
IPC: H05B/
Filed: 1987-10-22
Abstract: A food container for use in a microwave oven is disclosed. The container contains a plurality of food substances, and employs a metal shield to shield at least one of the food substances from microwave radiation. Arcing and other problems associated with the use of metal shielding are avoided by proper selection of the geometry of the metal shield. The metal shield is preferably looped in a manner which provides some electrical inductance, and the ends of the metal shield are overlapped and separated by a dielectric material to provide some electrical capacitance. The geometry of the shield is selected so that the inductance and the capacitance in effect form a "tuned circuit" which minimizes problems associated with resonance and which eliminates arcing.

Abstract: A method and an assembly for brewing beverages in portions, such as freshly brewed coffee, in packages (42), where at first an outer cup (6) is delivered to a filling means (5) conveying the cup below successive ingredient delivering means (8-11) and a water feeding means (12) for filling the first outer cup (6) with the desired liquid and corresponding flavourings. Then a filtering means (13) places a second, inner cup (15) on the surface (24) of the liquid in the outer cup (6), whereupon the inner cup (15) is pressed into the outer cup (6) by means of a piston means (19). The inner cup (15) comprises a bottom acting as a filter for the liquid. During the compressing of the two cups the liquid is enclosed in an air-tight space between the two cups, the volume of said space being gra­dually reduced during the compressing. This results in a filtering of the liquid in the outer cup (6) upwards into the inside of the inner cup (15) during the compressing. The residue is left between the two cups. The resulting package (42) is then ready to be delivered. The two cups forming the package (42) are suitably formed in such a way that their top edges engage each other by snap action, thus resulting in a stable unit. The enclosed residue is removed together with the package (42) being thrown away, when the beverage has been consumed.
