Patent DE-3145977-A1 (DE)
Title: Vertical block breech on firearms
Inventor: WEIDINGER HEINRICH
IPC: F41C7/02
Filed: 1981-11-20
Abstract: Block breech on firearms with breech and lock-mechanism control by the actuation of the front stock in conjunction with a selective inclusion of the lock mechanism in the breech actuation. The essential disadvantages of the known block breeches are eliminated by means of the invention. The front stock instead of the trigger guard now serves as a handle for the operation of opening the breech. The breech block is moved vertically by a control rail which is mounted movably in the bascule and which has a control cam. By means of a tensioning slide located on the disc, the lock mechanism can be selectively included in the opening operation or disconnected. There is therefore the possibility of automatic or manual tensioning of the striker spring. It is to be stressed that the firearm remains closed during the breech opening until the block has descended. No trigger, breech or lock parts project outwards. The operating and handling reliability are thereby substantially improved. The mounting of the horizontally movable front stock on a guide bar seated in the bascule ensures a complete separation of the barrel from the stock. Finally, attention is drawn to the small number of movable parts (see the drawing according to Figure 2) and the simple production, maintenance and handling of the novel block-breech mechanism. <IMAGE>

Title: Process and device for braking a winding machine
Inventor: KOSLOWSKI GERHARD
IPC: B65H23/198
Filed: 1982-06-16
Abstract: In order to protect the material, fed in web form, during braking of the winding machine, the winding diameter is constantly measured during winding, the winding rate is constantly measured or maintained constant. During the braking operation, using the last measured values, the braking force of the braking device (10) of the winding carrier is then adjusted according to the measured or known winding rate and according to the measured winding diameter, the braking force of the braking device (11) for the roll (5) that the material (4) is looped around or at a tangent to is adjusted according to the measured or known winding rate and, if existing, the braking force of the braking device (12) for a roll (7) in contact with the winding (3) is adjusted according to the measured or known winding rate. The individual braking devices (10, 11, 12) are matched to one another with respect to the magnitude of their braking force, taking into account their constructional design, so that an at least approximately equal chronological sequence for the reduction of the circumferential speed of the individual rotating parts results. <IMAGE>

Title: Circuit arrangement for converters
Inventor: BRAKUS BOGDAN DIPL ING
IPC: H02M3/335
Filed: 1982-11-11
Abstract: The power semiconductor switch (T1 to T6) which is arranged in the load circuit of a converter and can be switched on and off periodically by an external clock source (UCLOCK) is controlled by three power MOS field-effect transistors (SIPMOS T7, T8, T9). One (T7) of these transistors connects the control electrode (B) of the power semiconductor switch (T1 to T6) via a capacitor (C4) periodically to an auxiliary voltage source (UH) and causes sudden switching over by means of the charging current of the capacitor (C4). A further transistor (T8) periodically switches on a low-resistance feedback circuit for the power semiconductor switches (T1 to T6). The third transistor (T9) causes an abrupt clearing out of the control path (BE) of the power semiconductor switches (T1 to T6) by periodic connection of an opposing voltage (UG) in the switched-off phases of the clock source (UCLOCK). <IMAGE>

Patent DE-3246535-A1 (DE)
Title: Grilling device
Inventor: WOLF GEB BLUM
IPC: A47J37/07
Filed: 1982-12-16
Abstract: In a grilling device, the components, for example the grid, receiving the items to be grilled are mounted so as to be swivellable relative to the heating device about an essentially vertical axis so that, when the grid is swivelled into an appropriate position, the items to be grilled can be placed thereon or removed therefrom without substantial hindrance by the heating device. On the other hand, it is possible to operate the heating device with the grid or the like swivelled away from the heating device without hindrance by the grid. The latter can project freely from a crossbar situated near to one of its ends so that the individual parts forming the grid can vary their length freely under the effect of the heat so that the distortion occurring in customary grids is avoided.

Abstract: Located at the upper ends of the lateral bars which are fastened on the left-hand and right-hand edge of the bed is a reading support or a book and newspaper holder - a plastic disc. A book or a newspaper is laid on this plastic disc and can then be read comfortably while lying on the back and without using one's arms. It is merely necessary to turn over the pages. Due to the fact that two clamps are present at the upper frame of the plastic disc, a newspaper is prevented from slipping. Two bookrests preventing books from falling down are fitted on the lower frame of the plastic disc. The book and newspaper holder can be adjusted in height in order to obtain the correct reading height and, in addition, can be rotated in order to obtain the correct reading angle and angle of inclination.

Title: Process for the cooling of thermally highly loaded spaces and arrangement for performance of the process
Inventor: SMETS BERNHARD DIPL ING
IPC: H05K7/20
Filed: 1983-08-13
Abstract: The invention relates to a process for cooling thermally highly loaded spaces, especially such with electrical and/or electronic switchgear, data processing installations or the like, and also an arrangement for performing the process. The supply air, with a different temperature in the space zone to be cooled, relative to the space temperature, is fed from above to the space zone to be cooled such that a downward-directed piston-like forced flow is formed, extending over the respective path width and length, between the rows of cabinets or shelves. The air flows in in the lower region of the rows of cabinets or shelves and is heated there while cooling the electrical and/or electronic devices, and thereby rises up by thermal buoyancy through the rows of cabinets or shelves. The air exits in the upper region of the rows of cabinets or shelves and flows to below the ceiling of the space, to be sucked out there.
