Patent DE-3101472-A1 (DE)
Title: Expanding plastic dowel
Inventor: BAPPERT ADOLF
IPC: F16B13/12
Filed: 1981-01-19
Abstract: The expanding dowel has a slot which runs over most of its length and by means of which two expanding legs (14, 16) are formed. A receiving channel (4) running in the direction of the dowel axis widens into a cylindrical part (8) into which the initial part of a screw can be pushed without the dowel being expanded in the process. In the region of this cylindrical channel part (8) there are integrally formed, on the inner wall of the dowel, two elevations (70) which are arranged in the longitudinal direction of the dowel such that they are offset corresponding to the pitch of the thread of a fastening screw, with the result that they can be screwed into the thread of the fastening screw without the dowel being subjected to a considerable amount of force in the process. By means of the elevations (70), the dowel can be connected to the screw, with the result that, with the aid of the screw, it can be pushed into a bore and also drawn out again. At that end of the dowel opposite the channel part (8), the expanding legs (14, 16) are connected to one another by web parts (40), which form predetermined breaking pieces and are arranged on both sides of the central axis of the dowel, with the result that the screw is prevented from yielding laterally when the dowel is expanded. <IMAGE>

Title: Process for generating an SO3-containing gas for exhaust gas purification in the electrostatic precipitator
Inventor: REISSMANN HELMUT DR
IPC: B01D53/86
Filed: 1981-03-14
Abstract: By combustion of sulphur, fed in liquid form, with combustion air in a furnace, an SO2-rich combustion gas is generated. This combustion gas is subjected to a catalytic conversion for enriching SO3 and the SO3-containing gas is admixed to an exhaust gas before purification in an electrostatic precipitator. An air heater is provided for the combustion air. The temperature is measured at the inlet or outlet of the catalytic conversion of the SO2-rich combustion gas and either the flowrate of cold air fed to the combustion gas or the flowrate of the combustion air passed to the sulphur combustion is regulated by this temperature. The air heater is regulated on the basis of the sulphur metering. The sulphur metering can be controlled via measurement of the dust content in the clean gas leaving the electrostatic precipitator.

Patent DE-3127748-A1 (DE)
Title: Method and apparatus for feeding elongate workpieces
Inventor: WEPNER JOACHIM ING GRAD
IPC: B23Q16/00
Filed: 1981-07-14
Abstract: The invention provides a method and an apparatus for feeding elongate workpieces. Although, at present, rapid feed is intended, the kinetic energy absorbed is considerable, especially with elongate workpieces, so that a reduced speed, the so-called creep speed, has to be chosen sufficiently long before the stop is reached. This makes two switches necessary in all cases, and these must be positioned a considerable distance apart in order to be able to catch workpieces reliably even in the case of the maximum possible kinetic energy of the latter. As a result, there is a necessity both for a travel of corresponding length and also for a time, corresponding to this travel, for the adjustment of the workpieces. In order to reduce both of these and in order, furthermore, to avoid the need to provide more than one switch, the invention uses a single switch to switch off the drive at full conveying speed, after which the workpieces continue over the feed section without being driven. The workpiece is then subjected to a drive with a greatly reduced speed and this is switched off when the workpiece triggers the switch from the opposite direction. The last conveying speed, acting in the opposite direction, is sufficiently low to ensure that the workpiece comes to a halt when the drive is switched off.

Title: Armour-piercing conflagration projectile
Inventor: JENUS JUN JOSEPH
IPC: F42B10/46

Abstract: The invention relates to an armour-piercing conflagration projectile which, according to the invention, has a cylindrical metal body (12) designed as a solid body, with an inner cavity (14) arranged in its front region and with an orifice (15) pointed in the direction of movement of such a projectile (10), the cavity (14) having solid side walls (13) extending parallel to the direction of movement and so designed that they essentially preserve their initial form at the start of penetration of the armour by the projectile (10), in order, at the moment of impact with the armour, to produce a completely closed cavity (14), so that adiabatic compression is possible within the cavity, has a conflagration composition (20, 20a) which at least partially fills the cavity (14) and which, triggered by the adiabatic compression, burns in an explosive manner, and has a protective windshield (18) which closes the orifice (15) of the cavity (14) and forms the nose (18, 18a) of the projectile, with the result that it becomes possible to modify armour-piercing training projectiles into armour-piercing conflagration projectiles and to bring about the effects of the conflagration projectile on the rear side of the armour, thereby reinforcing the conflagration effect of such projectiles. <IMAGE>
Patent DE-3240582-A1 (DE)
Title: Pipe flange
Inventor: KESSEL BERNHARD
IPC: F16L43/02
Filed: 1982-11-03
Abstract: The invention relates to a flange for a flange connection which is integrally formed externally on one pipe on or near to the pipe end and, at the ends, has a circumferential holder for an elastic sealing means, and can rest subject to pretensioning of the sealing means against an opposing flange which is constructed on the ends and is at least approximately identical, it being possible to press the flanges against one another by attachment means. In the case of flange connections consisting of two such flanges, it has been found to be difficult to achieve a reliable seal, since production tolerances or slight axial inaccuracies in the connecting region resulting from the stiffness of the flanges exacerbated the problem of loading the sealing means uniformly circumferentially. This is prevented according to the invention in that the end side of the flange has a circumferential recess at a distance radially inside the holder, which recess forms a desired bending point with a reduced wall thickness in the transition region from the pipe wall to the flange. This desired bending point permits uniform loading of the sealing means and a perfect seal.
