Title: Electromechanical control for cassette drives, particularly in car radios
Inventor: HAPKE WALTER
IPC: G11B15/44
Filed: 1985-06-08
Abstract: In an electromechanical control for cassette drives with open-ended magnetic tape as recording medium, particularly in car radios, the automatic direction change of the magnetic tape and the programme search system are to be controlled with the least possible complexity of electrical and mechanical switching means. For this purpose, according to the invention a rocker W known for the alternate pressing of the magnetic tape against the capstan shaft driving in each case and controlling the rubber pressure rollers GA1 and GA2 is rotatably supported on a swing H2, which is rotatable to a limited extent, and controlled for the tape direction change by a first pulse magnetic M1. The mechanical arrangement of this pulse magnet M1 at the same time controls the transmission of the driving mechanism via a link V. The swing H2 placing the sound head T against the magnetic tape is also supported tiltable to a limited extent by means of a rotary bearing L2 on the chassis and adjusts the sound head T to recording/replaying or programme search and fast forward and reverse, independently of the direction of travel of the tape. As a result, the mutually independent change, simultaneous or staggered in time in any sequence, of the various operating states of the drive becomes possible with the least possible complexity of control elements and in the smallest possible space, in conjunction with the usual electronics. <IMAGE>
Patent DE-3520969-A1 (DE)
Title: Card holder for typewriters or printers of similar design
Inventor: MUDDER WOLFGANG
IPC: B41J13/12
Filed: 1985-06-12
Abstract: The purpose of card holders in typewriters or printers of similar design is to press a sheet of paper or a card to be printed or any other document against the platen so that there is no gap between the recording medium to be printed and the platen located behind it during the printing of a character. Below the typing line, this card holder has a cutout into which, during printing, the elastic arms of the daisywheel with types arranged at their free ends are inserted. During the printing of recording media from the upper down to the lower edge, the corners of the recording medium very easily become hooked in this cutout, as a result of which the recording media may even be damaged. The invention is based on the object of allowing interference-free printing of recording media from the upper down to the lower edge. This object is achieved in that the cutout is covered on its side facing the recording medium by a membrane which is resilient in the impact direction of the types. The card holder designed in this way makes it impossible for the printed recording medium to become hooked. <IMAGE>

Title: Electrical switching element having a printed circuit board
Inventor: SPRANGER DIETER
IPC: H01H13/70
Filed: 1986-02-06
Abstract: Known electrical switches have two contact points which are arranged electrically isolated from one another and are provided with connections, and which, furthermore, can be brought into touching contact with a sprung, electrically conductive bridge element, for switching. In the case of known switches, the contact elements consist of noble metal, for example of silver conductive varnish, which is highly sensitive to corrosion. In addition, contact points made of noble metal are too expensive for mass production. The invention is based on the object of creating an electrical switch having a printed circuit board which can be produced simply and cheaply, has a long life and can be used widely. This object is achieved in that both the contact points (6, 7) of the copper coatings (8, 9) on the printed circuit board (3) and the contact links (11) on the contact foil (5) are applied exclusively by means of a low-resistant graphite layer in a suitable coating process, for example partially by screen printing. In consequence, electrical switches having a long life are created, since the corrosion and migration effects which are known from the use of silver are avoided.   <IMAGE>

Title: Apparatus for deburring castings
Inventor: HEINKE JUERGEN DIPL ING
IPC: B22C9/18
Filed: 1986-05-24
Abstract: The invention relates to an apparatus for deburring castings with large tolerance ranges. The aim of the invention is to carry out the deburring operation at a lower cost and with less work. The object on which the invention is based is therefore to develop an apparatus for deburring castings with large dimensional tolerances by means of which it is possible to remove the burr completely from the casting having set the apparatus just once to the maximum dimension of the said casting. According to the invention, this is achieved by virtue of the fact that a cutting or press-off part and, at the same time, a drawing die displaceable horizontally against an elastic element are arranged on the tool holders of a deburring apparatus. The drawing dies are arranged in such a way that they project from the tool holder by at least half the tolerance of the dimensions of the casting. The elastic elements ensure that the drawing dies are pressed continuously against those parts of the casting which are to be deburred. To improve burr removal, the drawing dies can be provided with cross grooves.
