Title: Massage method as well as arrangement and device for carrying out this method
Inventor: NEMETH LASZLO
IPC: A61H23/02
Filed: 1983-05-03
Abstract: In conjunction with an arrangement and applicator for carrying it out, a massage method is described in which one or more electrical or mechanical oscillations are transferred to the body via one or more applicators. It is essential that the applicators are controlled by means of non-monotonic signals which are derived from primary signals, for example in the form of music, speech etc., by Fourier analysis. In addition to the derived non-monotonic signals, the patient can also be offered the primary signals, for example in the form of music. The arrangement for carrying out the method has one or more frequency-dependent filters with upstream and/or downstream amplifier stages as well as possibly at least one signal convertor for the output signal. The applicator consists, for example, of a hollow rod closed at the front and having electromechanical oscillation generators arranged therein. Arranged coaxially behind one another in the interior of the hollow rod (10) are two vibrator motors (12; 13) whose connecting leads (20, 21) are led separately to the outside. <IMAGE>

Title: Container for receiving and transporting sensitive objects, in particular foodstuffs
Inventor: HELDELE HANS
IPC: B65D1/22
Filed: 1983-11-30
Abstract: The invention relates to a container for receiving and transporting sensitive objects, in particular foodstuffs, consisting of two semi-shells which are produced from plastic film by thermoforming and can be opened out at a hinge-type connecting edge and interlocked with one another by a fastener. The purpose is to construct a container of this type in a simple manner in such a way that it can be gripped and carried easily. For this purpose, corresponding gripping troughs are moulded into the semi-shells near to the edge, but with spacing from the edge, by curving the films over their entire thickness. A different spacing of the gripping troughs from the edge and curves between the gripping trough and the edge provide a secure grip on one side for the thumb and on the other side for the fingers of the hand holding the container. In an advantageous further development, by means of the additional construction of a standing side with a wall portion running obliquely downwards from the edge, the possibility is provided to collect liquid belonging to the contents of the container in the bottom region remote from the edge and to keep the remaining contents largely separate therefrom.

Patent DE-3417233-A1 (DE)
Title: Radio communications system
Inventor: LANGEWELLPOTT ULRICH
IPC: H04W28/04
Filed: 1984-05-10
Abstract: The system codes the digital signals using an error recognising or error correcting code. The movinq stations also set the transmit power of the fixed stations depending on the transmission quality. The criterion for the transmission quality is the frequency with which transmission errors are recognised or corrected. Alternatively if the digital signals are represented by a code word then correlation takes place at the receive end and the ratio of the highest to the next highest correlation peak is used as criterion for transmission quality.

Title: Drive device for different functions in typewriters or printers of similar design using an electric motor
Inventor: RIX ALBERT
IPC: B41J25/316
Filed: 1984-06-01
Abstract: In typewriters or similar office machines, it is known, for example, to use either a separate drive element in each case or a common drive motor for a plurality of drive functions. Changing the function in a common drive motor is possible according to the prior art by reversing the direction of rotation of the drive motor or by actuating interposed couplings. The invention is based on the object of providing a common drive device for different functions in typewriters or similar office machines which is not very complex and allows a simple and space-saving construction. This object is achieved in that the stator and the rotor (11) of a stepping motor (12) can be blocked or driven alternately either on a first or on a second drive device for selective transmission of the energy supplied by the motor (12). Since different functions can be driven via the stator and the rotor (11) of the same stepping motor (12), an inexpensive drive device is provided. <IMAGE>

Abstract: The invention relates to an installation for separating printed material, with a separating station in which the printed material is removed from a container (7) containing a stack of printed material. The containers (7) which contain a displaceable floor (16) are inclined in the separating station (15) towards the removal side. The separating station contains a lifting device (17-22) for the container floor (16); a holding-down device (26) and a suction device (28), which are both vertically movable, above the container; and an inclined slide plate (35) which is movable between a forward position overlapping the top of the container and a position exposing the top of the container, and is situated on the removal side of the container in the region of the top of the latter. The container floor (16) is raised in each removal cycle, until the top printed item in each case is positioned adjacent to the top of the container. Then the holding-down device (26) and the suction device (28) move downwards. As a result of this, the top printed item is pressed downwards, and the suction device (28) sucks up the edge region of the printed item. Then the suction device (28) is raised and the slide plate (35) moves forwards, so that the printed item is gripped from below. Then the holding-down device (26) is raised as well, so that the printed item slides outwards across the slide plate (35) once the suction device (28) has been aerated. Simultaneously or ...
