Title: Display device control (visual display unit control) for producing a data stream in the manner of pixels
Inventor: STEIGER HEINZ-WERNER DIPL ING
IPC: G09G5/395
Filed: 1988-08-12
Abstract: The invention relates to a display device control for producing a data stream in the manner of pixels. Picture refresh stores (BWS) of conventional display device controls are constructed using specific memory chips (SBi), so-called video-RAMs. These memory chips (SBi) provide a parallel stream of data which has to be serialised before the imaging on a display device (SG). The display device control according to the invention produces a data stream in the manner of pixels, with little outlay in terms of security, this display device control being also suitable for high-resolution display device (SG). The invention is used in display devices. <IMAGE>

Title: Method for burning off cathode ray tubes by means of the anode high-voltage source of a visual display unit
Inventor: MUETER ULRICH
IPC: H01J9/44
Filed: 1989-05-17
Abstract: When regenerating the cathode of a cathode ray tube, gas atoms and molecules (O, C, CO, CO2) and, to a very limited extent, metal particles and their compounds (Ba, Sr, Ca, BaCO3, SrCO3, CaCO3) emerge from the cathode surface into the vacuum. The metal particles and their compounds are deposited loosely as impurities on electrodes, glass wall and getter in a random manner. As a result of these impurities, high-voltage flashovers occur in the evacuated glass tube of the cathode ray tube between the anode and the "other electrodes" during the operation of a regenerated cathode ray tube in a visual display unit. The flashover energy often destroys semiconductor components in the picture-reproducing device, in which the cathode ray tube operates. The invention has the purpose of cleaning the interior space of the glass tube by burning it off with high voltage. In the inventive method, the anode high-voltage of a picture-reproducing device is used. The anode of a cathode ray tube which has been contaminated by regeneration is in this case connected to the positive terminal of the anode high-voltage source and the other electrodes of the same tube are connected via a separate device to the negative terminal of the same anode high-voltage source. When switching on the high-voltage- supplying picture-reproducing device, flashovers occur in the connected, regenerated cathode ray tube. The discharge energy ensures that the free particles in the discharge path ... Original abstract incomplete.

Title: Die forging process for spiral bevel gears - uses modified tooth geometry to allow simple extraction of gear forging from one-piece die
Inventor: ELSNER WOLFRAM LOTHAR DIPL ING
IPC: B21K1/30
Filed: 1989-06-12
Abstract: The geometrical conditions needed to allow bevel-,  hypoid-, or hyperboloid gears, are described. The method is esp.  for pinions with small bevel angle, to be produced by forging in a one piece die. If the necessary geometric conditions are applied to the tooth profile the forging can be simply removed from the die with a screw motion of constant lead. A master gear of the required tooth geometry can be produced by conventional machining and then used to produce the die, by e.g. spark erosion. USE/ADVANTAGE - The production economies of forming in a simple one piece die can be realised.

Title: Forming thermoplastic backed carpets - using tool having movable segments at areas of high carpet extension to give more uniform heat extraction and reduce cycle times
Inventor: JORNS DIETER
IPC: B29C51/08
Filed: 1989-11-17
Abstract: Heated carpet strip is placed in the lower half of a tool which is then closed by an upper half. Areas of the carpet which are subjected to higher elongation stresses can be locally pressed with a higher pressure with the result that more uniform cooling of the carpet is achieved and therefore processing time is reduced. The tool comprises upper and lower halves which are segmented to enable higher local pressures to be applied at desired areas.

Title: Parallel rotating discs for wet-cleaning combustion gases - passes collected combustion fume particles through chemically-laden water bath for removal by scrapers
Inventor: NIEDERGUENZL JAKOB
IPC: B01D53/74
Filed: 1990-02-14
Abstract: Combustion fumes which in addn. to gases are charged with ash, unburned fragments travelling sparks etc. travel between the inlet and outlet of a channel (5) opening the top of a container filled with water up to the level of the channel base. A motor-driven shaft submerged in the water carries a series of spaced discs whose rotation carries them both through the water and the travelling fumes, wherein the discs pick up solids. As the discs turn in the water, such solids are removed by pivotably mounted scrapers in the inter-disc spaces, and fall towards a periodically opened base outlet. The water is charged with additives such as lime for chemically reacting with gaseous pollutants such as SO2. For larger installations, a number of rotating disc assemblies are arranged in linear sequence all turning within the same container and fume flow channel. ADVANTAGE - Simple but robust and reliable unit deals effectively with spent-laden fumes.

Title: Plastics bag shaping shoulder production method - mills from cast blank to produce free-forming surfaces
Inventor: KAUFMANN MATTHIAS DIPL PHYS DR
IPC: B29C53/82
Filed: 1990-12-06
Abstract: The method produces a shaping shoulder for a machine producing hose-shaped bags of plastics sheet. The latter is delivered continuously to the shoulder, which forms a continuous hose with overlapping lengthwise edges, which are then sealed together. The shoulder comprises a tubular central portion with integral collar, whose surface is formed by sharp edges converging to an apex at the end of the tubular portions, so as to form a deflecting edge for the sheet. A blank for the shoulder (1) is cast, to give the collar (3) height, the tube internal diameter (2), and the angle between the edge of the tube and the collar, while allowing for machining. The shoulder is then milled out to produce free-forming surfaces. ADVANTAGE - Precision and low rate of wear.

Title: Slitting machine - has compressed air cylinders to set the cutter head into rigid position
Inventor: SUPE-DIENES RUDOLF DIPL ING
IPC: B26D5/04
Filed: 1991-02-14
Abstract: On slitting machinery, the cutter head with a circular blade is depressed and set laterally by means of compressed air cylinders. The cylinder top cover is bored off centre for a piston shaft of a smaller diameter than the piston inside the cylinder. In this manner the piston to which the cutter head is attached is unable to move radially. Pref. the cutter head (10) has a circular blade (11) and guard (12), with a compressed air cylinder adjustment (13) to avoid vibration. The head (10) is fixed at the end of the piston shaft (14b) of a compressed air cylinder (15) which has a base (18) and a cover (17). The air enters through the passage (30), acting against the piston (16). Anotehr piston shaft of smaller dia. (14a) protrudes upwards, and through a bore of suitable dia. in the cover (17). Position of the bore in the cover is offset from centre, which prevents the piston (16) from moving radially.  Furthermore, the piston shafts (14a,14b) may be mounted in ball bearings, placed within the cover (17) and base (18). As an additional prevention of vibration, a small compressed air cylinder is fixed sideways to the shaft (14a) between the piston (16) and cover (17). End of the cylinder shaft is V shaped, to grip against the shaft (14a) when the slitter head has already been set into position. In the base (18) the shaft (14b) has extra packing to stabilise it when the top shaft (14a) is gripped in the above manner. ADVANTAGE - Slitting blade can be set precisely, without the adjustment of numerous small parts. Head can be moved for left or right hand use.

Inventor: WILKENS GUENTER
IPC: B23K26/26
Filed: 1991-04-23
Abstract: In welding together two strips or sheets using an energy beam, additive material (36) in the form of strip is positioned between the edges of the sheets in a weld gap by end positioning device (47) and moveable means (39) which can move parallel to the gap (31) on guide rail (50). Once clamped in position by moving one of the sheets, the additive strip is welded to the two sheets by a relative movement of the energy beam and the assembled sheet arrangement. ADVANTAGE - Welding is carried out without an expensive guiding device for the strip (36) or weld bead.
