Title: Method for increasing the load carrying capability of installed low-voltage power distributor systems by means of central control of the switching of periodic loads
Inventor: SLOSAR GABOR
IPC: H02J13/00
Filed: 1987-06-02
Abstract: The invention relates to a method by means of which periodic loads - which only need to be supplied at time intervals - are subdivided into predetermined groups and subgroups. This avoids or reduces peak loading of the distribution system due to the fact that the loads are connected step by step to the distribution system. An address is allocated to each subgroup. The loads of one subgroup are controlled by audio-frequency code telemessages which contain both the address of the loads to be controlled and the control command to be executed. Code messages are superimposed on the power system voltage by an audio frequency control centre. The code telemessages preferably contain 50 clock pulses and in each case contain a start signal and a combination of signals and signal blanks allocated to predetermined clock pulses. <IMAGE>

Title: Holding device for the needles of a tufting machine
Inventor: SCHINDLER HEINZ
IPC: D05C15/20
Filed: 1987-07-03
Abstract: In order to achieve a varying patterning in tufting fabric, it is known to bring selectively into use different needles which supply threads of differing colouring and/or structure. The needles are arranged on the needle carrier so as to be axially displaceable. There is to be provided a new holding device for the adjustable needles of tufting machines which is of simple construction and which works accurately and reliably. In the new holding device, the needle bar has a circular cross-section, the needle carriers being mounted rotatably on the needle bar, so that, each time, one needle is in the working position pointing downwards, whilst the other needle is pivoted outwards and upwards out of this working position, so that it cannot come into contact with the tufting fabric. Since, in the new holding device, the needle carriers together with the needles arranged on them are pivotable about a horizontal axis, during adjustment the needles are not moved out of the plane in which they must be located in order to be capable of cooperating with the loop grippers or loopers serving as a counterelement. The pivoting of the needle carriers is to be carried out in an uncomplicated manner and accurately, so that adjustment between the position of rest and the working position takes place extremely reliably.

Title: NMR tomograph for body sections
Inventor: BOCKISCH ANDREAS DR MED DR RER
IPC: G01R33/38
Filed: 1987-09-28
Abstract: By contrast with the currently conventional whole-body tomographs, the NMR body part tomograph described permits lateral access to the patient for the purpose of body part tomographs; the axis of the magnetic field is thus arranged perpendicular to the body axis. All the electromagnetic coils of the body part tomograph are of much smaller dimensions, with the result that only body parts such as, e.g. the heart, brain, orbiter (eye sockets), joints, female breasts, and sexual organs are examined. The result is equally low production and maintenance costs, and an improved spatial resolution, as well as an improved signal-to-noise ratio.
