Patent DE-4222003-A1 (DE)
Inventor: GROCH HANS-WERNER
IPC: B25C5/02
Filed: 1992-07-04
Abstract: The invention relates to a stapler with a staple magazine (22) to take strips of staples with their sides guided between side walls of the staple magazine (22) and a staple feeder (28), sliding in a guide (60) of the staple magazine (22), formed from bent sheet metal, which can be pushed by the fronts (50) of two mutually parallel sides (44) against the sides of the strip of staples (41) in the staple magazine, under the effect of a spring (26). In order to ensure that the staple feeder bears on the sides of the staples without jamming even when thin-walled material is used, the sides (44) of the staple feeder are transversely deformed (48) to form a corner, at least in the region of their frontal edges (50).

Title: Top dead centre detector for four-stroke IC engine - has intermediate shaft between crankshaft and camshaft driven with uneven ratio and with sensors and coincidence circuit
Inventor: KUENNE ANDREAS DIPL ING
IPC: G01M15/06
Filed: 1992-07-09
Abstract: The camshaft (9) is driven at half the speed as the crankshaft (1) via an intermediate shaft (5) and various sizes of pulleys. The ratio between the crankshaft and the intermediate shaft is less than unity and the intermediate shaft has two diametrically sited markings (6, 7) and a fixed position sensor. A single marking and fixed sensor on the crankshaft completes the system. The sensor outputs are processed by a coincidence circuit (11) linked to the ignition. The system detects the TDC twice in every firing cycle and discriminates between the two points, via the marking sequence preceeding the two points. No markings are required on the camshaft other than a visual marking for assembly. ADVANTAGE - Failsafe identification of TDC.

Title: Twin belt yarn traverse for winder - has convex inlet guide ridge for improved yarn control at reversal points
Inventor: ARETZ FRIEDHELM
IPC: B65H54/28
Filed: 1992-07-20
Abstract: A yarn traverse for making cross wound packages has two traverse belts with yarn hooks running in opposite direction . At least one stationary yarn guide lifts the yarn over the top of the hooks at the reversal points. A yarn inlet guiding ridge (18) with an outwardly curved guiding contour (19) has reversal points (21) which lie on the extension of the winding angle (g) of the yarn (17) on the package (3) just before yarn transfer takes place. Pref. two belts (9,10) run in opposite directions (T1, T2) and are fitted with entrainment hooks (11,12). A stationary guide (7) has a linear guide surface (15) with ramps (16) at the ends which transfer the yarn (17) from one belt hook to the other. A guide (8) has an overhang (14) which prevents the yarn from jumping out of the guides during transfer. USE/ADVANTAGE - Improved yarn control at reversal points for twin belt traverses. Curved guide ridge reduces tendency for uncontrolled yarn movement towards the centre at moment of transfer from one belt hook to the other.

Title: Handwriting input device with integral display surface and coordinate detector - has marker device enabling any position to be marked, memory for range definition and coordinate position values
Inventor: SAKAMOTO HIROYUKI
IPC: G06F3/048
Filed: 1992-09-11
Abstract: An integral display input device (10) provides an input surface  by integrating a display device (11) and coordinate detector (12). Any position can be marked on the input surface with a marker device (13). An input range defined by a processing function is stored (21) with range position data for entry of coordinate values corresp. to the input range. The stored range data are displayed (22) and coordinate values checked (20) for coincidence with the stored range. If the coordinates lie within the range the function is computed. A range offset device shifts the display control data and stored range position data. USE/ADVANTAGE - Simple handwritten data entry is achieved for several users using coordinate data entry via a tablet, e.g. for sales applications.

Patent DE-4239236-A1 (DE)
Inventor: HINTZE WOLFGANG DR ING
IPC: B23B27/14
Filed: 1992-11-21
Abstract: The invention relates to a polygonal cutting insert (10, 19) with raised chip shaping components (18) on the face (12) which are arranged side-by-side in a row at a distance from the cutting edge (13, 20) and which extend longitudinally with a longitudinal axis thereby defined which forms an angle to the perpendicular to the cutting edge in the face plane. To guide the chips better and to ensure reliable material removal with the lightest possible load on the cutting insert, it is proposed that the raised chip shaping components (18) take the form of longitudinal ribs and be directed substantially in the direction of the chip flow. The crest of the rib arch is at a minimum (182, 184) when viewed along the side or along the side longitudinal cross section and a maximum (183) in a region further from the cutting edge or has the same height as a central face plateau raised above the cuttine edges (13, 22) or corners.

Title: High power air filter for a passenger compartment for use in passenger cars and lorries
Inventor: HEIN KARL DIPL ING
IPC: B01D46/10
Filed: 1993-02-09
Abstract: The increase in road traffic makes the use of a filter for the passenger compartment appropriate. The filter cleans the sucked-in ambient air of particles and noxious substances. The filter consists of the following three stages:   1) The air is firstly directed through a filter paper or non-woven. The air is firstly cleaned of coarse particles. 2) In the second part the air is directed through a packed bed of activated carbon or charcoal. Here, the noxious substances are largely adsorbed out of the air. Depending on the dimensioning and composition of the filter the filtering of the air can be optimised. After the packed bed a second filter paper or non-woven is arranged which only has a supporting function. 3) The last part consists of a miniature electric filter with negative spray electrode and positive precipitation electrode. Here, the fine dust is removed and precipitated on the inner wall of the tube.   A variation in the spray electrodes permits the separation behaviour to be optimised. This filter can be installed in new vehicles and used vehicles.

Patent DE-4307449-A1 (DE)
Inventor: SANCHEZ CLIFTON W
IPC: H04L29/08
Filed: 1993-03-10
Abstract: A synchronous serial communication link (10) between a controller (14) and a peripheral (12) is resynchronized by the sending of a series of bits at a first logic level (logic one) by the controller. The series of bits is long enough to ensure that the peripheral will decode a command word in which all of the bits are at the first logic level. The peripheral, upon decoding such a command word, resets the synchronization circuitry within the peripheral. The controller then sends a single bit of the opposite logic state (logic zero) followed by serial data. The peripheral, upon receipt of this bit of the opposite logic state, releases the synchronization circuitry from its reset condition and begins to decode the serial data in synchronization with the controller. <IMAGE>

Title: Sorption plant for cleaning industrial exhaust gases
Inventor: HELLMICH FRIEDRICH
IPC: B01D53/08
Filed: 1993-10-26
Abstract: An inexpensive sorption plant is to be created which, apart from fluorine contaminants, sorbs other gaseous pollutants. The operating costs are to be relatively low. The maximum throughput rate is to be in the range of 50000 m<3>/h. In the novel sorption plant, four cascade blocks (16 to 19) are installed within the reaction vessel (10). Two cascade blocks lie above each other and next to each other in each case. Cooling medium lines (22) are mounted transversely to the cascade sheets (20, 21). Within each cascade block (16 to 19) the plant operates in the cross-flow mode and, seen as a whole, operates in the counter-current mode. The dirty gas inlet and the cooling medium outlet are assigned to one cascade block (16). The clean gas outlet and the cooling medium inlet are assigned to another cascade block (19). The sorption plant according to the invention is particularly applicable to the cleaning of flue gases for relatively small industrial plants. <IMAGE>
