Title: Tubular turbine as means of propulsion
Inventor: SEYERLE FRIEDRICH WILHELM DR I
IPC: F02C5/04
Filed: 1983-02-28
Abstract: In order to simplify the design of existing turbines used as means of propulsion, the tubular turbine is used which comprises a U-shaped tube supported in the axial direction and rotating about the axis, in which a fuel mixture is drawn in at one side, is radially highly compressed by deflection and self-ignition and combustion occurs in the radially most remote position, the tube continuing to rotate and the exhaust gases at the other side producing a thrust movement on exit. The tubular turbine is started by compressed air from built-in air reservoirs or pressure chambers and in the operating state the pressure chambers are again brought to the required compression. A plurality of tubes may be supported about the axis. The chamber in which the tubes rotate consists of a vacuum. The shafts are carried on an air bearing. Dust is proposed as the fuel but all other known fuels can also be used.

Title: Apparatus for supporting and storing continuous stationery
Inventor: HERSE FRIEDRICH
IPC: B42F7/04
Filed: 1983-06-08
Abstract: The invention relates to an apparatus for supporting and storing continuous stationery which can be folded together in zigzag form (known as paper stock). The stack of stationery is to be supported and released again, and also stored, in a simple manner, but on the other hand with it being possible for the data printed on all sheets in the stack to be read without impediment. To this end, two lids (1, 2) which can be pivoted relative to each other are equipped on their inner sides with mountings for the releasable attachment of the first and last sheets (4', 4") in the stack of stationery or of extensions of the said sheets. In the folded-together state, the lids (1, 2) are at a certain distance apart at their point of connection (3), permitting the accommodation of the stack of stationery which is to be folded together. <IMAGE>

Title: Protective method for a power transistor
IPC: H03K17/082
Filed: 1983-06-25
Abstract: A protective method is described for a power transistor in which the collector-emitter voltage thereof is measured when the transistor is turned on and then the base control of the transistor is switched off to turn off the latter when this collector-emitter voltage exceeds a particular magnitude. When the transistor is switched back into the on state, the current peak of the transistor can rise to a rather high magnitude at any switching time as a result of which the service life of the transistor can be considerably shortened. This problem is eliminated by the fact that the transistor is only switched back to the on state under the condition that its collector-emitter voltage is close to zero, that is to say below a predetermined nominal value.   <IMAGE>

Title: Method and device for improving the milling capacity of a vibration grinding mill
Inventor: MEDER JUERGEN
IPC: B02C17/14
Filed: 1984-04-02
Abstract: When crushing solids, in particular when crushing glazing frits in a vibratory grinding mill agglomerations of material are formed between the grinding bodies, which agglomerations consist of already sufficiently finely crushed materials and materials which have not yet been crushed. Not only is the grinding affect greatly impeded by these agglomerations of material but also the flow of material through the mill is adversely affected. In addition, these accumulations of material in the vibratory grinding mill also have a disadvantageous effect on the throughput and require an increased expenditure of energy. These disadvantages are eliminated with the method according to the invention in that gaseous media are passed through the grinding pipe or the grinding pipes (10, 11) of the vibratory grinding mill. <IMAGE>

Patent DE-3434508-A1 (DE)
Title: Television transparency viewer
Inventor: ALERITSCH HELMUT
IPC: G03B23/00
Filed: 1984-09-20
Abstract: The television transparency viewer (DTB) enables transparencies to be viewed on the screen of any commercial television set. The DTB can be located stationarily directly underneath the television set. The DTB consists of three mains parts: the transparency projector (a), the pick-up optics (b) and the transportation system. The transportation system consists of 19 loading areas on which in each case a cassette containing 25 transparencies can be accommodated. The loading capacity is thus 475 transparencies. The cassettes are inserted individually via the loading flap (d) at the front of the DTB. The transportation system moves any desired cassette to the projector slide-in device (e). From this cassette, the desired transparency can then be moved into the projector slide-in device. The transparency projector accepts the transparency and images it side-reversed on a screen (1) in front of the transparency projector objective. The pick-up optics pick up the image side-correct from the other side of the screen and transmit it. When the pick-up optics are aligned for direct image pick-up, the screen is omitted. Other facilities: remote control (c), power supply (f), video input (g), video output (h), tape audio (i), receiving device for remote control (k), light-emitting-diode display (m). <IMAGE>
Patent DE-3441241-A1 (DE)
Title: Winding device
Inventor: SCHIPPERS HEINZ DIPL ING DR IN
IPC: B65H54/28
Filed: 1984-11-12
Abstract: The invention relates in particular to a crosswinding device with friction drive of the winding spindle 1 or of the spool 2 formed thereon. Since in crosswinding devices a geared drive connection exists between the winding spindle 2 and the traversing device 4, the torque for driving the traversing device 4 must also be transmitted by the filament layers which are in frictional contact with the driver roller 3. In order to reduce the possibility of damaging these filament layers, the invention provides an additional auxiliary drive 18, in particular a cumulative compound motor, which drives the traversing device 4 with a constant torque or with a torque which is controlled in dependence on the increasing diameter of the spool 1. <IMAGE>
