Patent DE-3105106-A1 (DE)
Title: Chip-clearing device
Inventor: EICK HEINZ VON
IPC: B23Q11/02
Filed: 1981-02-12
Abstract: The invention relates to a chip-clearing device for removing chips adhering between teeth of a metal circular saw. Used for this purpose is a rotatably mounted disc with peripheral, radially orientated clearing pins which, bearing against the rotating saw blade, at the same time impart the drive to the disc carrying them. Thus the pins in each case expel the chips held between the teeth. Since the clearing pins revolve at very high peripheral velocities in the case of carbide-tipped saw blades, they are subjected to considerable wear, so that a brush trimming or an elastic plastic has already been provided for clearing out the chips. However, these do not achieve the performance which can be achieved in the case of the clearing pins made of steel. In order to improve the durability of clearing pins while retaining the drive of the chip-clearing device from the rotating saw blade, the invention provides for the clearing pins on a ring variable in radial distance from the saw-blade plane. This ring ensures that the clearing pins in each case penetrate exactly into the central area of the tooth gaps and no longer inevitably come in contact with the tooth edges. The durability is thereby substantially increased.

Patent DE-3114080-A1 (DE)
Title: Device for guiding a projectile arrangement in a smooth barrel
Inventor: WALLOW PETER DIPL ING
IPC: F42B14/02
Filed: 1981-04-08
Abstract: A recess (24) having a front boundary surface (25), a rear boundary surface (27) and a supporting surface (30) which connects the two boundary surfaces to one another and is close to the axis are provided in the circumferential region (10) of a projectile arrangement for a smooth-barrelled weapon. The track of the supporting surface (30) is inclined with respect to a projectile longitudinal axis (which can be assumed to be horizontal) in the firing direction, in accordance with the arrow (S). An element (36), which is designed as a strip, in the essentially trapezoidal cross-section is located, in the original state shown, with a front surface (43) tightly against the front boundary surface (25) of the recess (24) and is held there by a transportation securing device (62) which is preferably elastomeric and is in the form of a round cord. It is preferably produced from a material having a comparatively high density. During the firing acceleration of the projectile arrangement in the direction of the arrow (S), the large mass inertia of the element (36) in the direction of the arrow (B) results in a relative movement with respect to the supporting surface (30) close to the axis, the supporting surface (50) which is remote from the axis and is arranged on the outside of the element (36) being displaced (see dashed illustration in Figure 2) in the direction of the arrow (R) against the inner surface (72) of the smooth barrel, being matched to any unevennesses in the inner surface (72), and thus guiding the projectile arrangement while preventing disturbing oscillations transversely with respect to the core axis of the smooth barrel. <IMAGE>
Patent DE-3115747-A1 (DE)
Title: Fan clutch
Inventor: VOY CHRISTIAN DR ING
IPC: F16D35/02
Filed: 1981-04-18
Abstract: The invention relates to a viscous fan clutch, in which the disc-shaped impeller is axially precision-guided in the region of its outer periphery in the housing of the fan clutch and is also sealed in this region. By this means, the tendency of the rotor to perform wobbling shocks is prevented, as a result of which the mounting can also be kept short axially. Furthermore, there is the possibility of the function of the separating wall between the working space and the storage space additionally being taken over by the impeller. As a result, fewer individual parts are necessary for producing the viscous fan clutch and its axial space requirement is particularly low.

Title: Fire-protection device
Inventor: MIRANDA MARIO J
IPC: E04B1/94
Filed: 1981-06-19
Abstract: The fire-protection device is used to protect a wide variety of buildings, which are located in the vicinity or on the edge of wooded areas or heathland, for at least some time, when there is a danger of fire, from the fire spreading by sparks flying. The fire-protection device has, for this purpose, a pressure vessel which is filled partly with water, as extinguishing liquid, and partly with a compressed gas. The pressure vessel is connected, via a connection line, to a series of spraying nozzles which are arranged at a suitable point on the object to be protected from fire. In the connection line there is provided a controlled outlet valve which can be opened by one or more temperature sensors on said object by means of an actuating device. A float valve prevents the compressed gas from blowing out. The fire-protection device is independent of the local water-protection system. It may, however, be connected thereto via a non-return valve and be filled up again from said system.

Title: Apparatus for the alignment of bottles having depressions in the bottom region in labelling machines
Inventor: WINTER HORST
IPC: B65G47/244
Filed: 1981-08-19
Abstract: In an apparatus for the alignment of bottles having depressions in the bottom region in labelling machines, in which the bottles, clamped between the plates (5) of a turntable (6, 7) and centering bells, run through an aligning and a labelling region, lifting rams (14), seated in the plates (5) and engaging on the bottle bottom, and cams (27), seated in the plates and engaging into the depressions on the bottle bottom, are coupled to one another by means of a positive control reversing the direction of movement. The positive control is formed by a double lever (22), on the longer lever arm of which the cam (27) and on the shorter lever arm of which the lifting ram (14) are articulated. Thus, when the cam (27) engages into a depression, the lifting ram (14) is lowered automatically. In this way, any slipping movement between the lifting ram (14) and the bottle bottom is forestalled, and the cam (27) is reliably prevented from running over. <IMAGE>

Title: Circuit arrangement for a receiver of binaural/stereophonic broadcasts
Inventor: BUHSE ULF DIPL ING
IPC: H04N5/60
Filed: 1981-09-18
Abstract: The invention relates to a circuit for switching a receiver, which is capable of receiving signals in accordance with the two-carrier method, from mono to stereo and from channel A to channel B and conversely. The circuit comprises two bistable flip flops which are controlled by a common switch which can be operated by the user and by code signals which are derived from the code frequencies relevant to the various types of broadcast. The control is effected in such a manner that, when the switch is operated, only one bistable flip flop can ever be switched (namely the one which is allocated to the respective code frequency). A logic circuit controlled by the bistable flip flop and by the code signals operates a change-over switch for switching to the type of reception desired in each case. <IMAGE>

Title: Method of soldering rapidly oxidising metals, in particular aluminium, in vacuo or under a protective gas after prior removal of the oxide layer by amalgamation
Inventor: TOELKE HANS-FRIEDRICH DIPL ING
IPC: B23K1/19
Filed: 1982-02-25
Abstract: In order to solder rapidly oxidising metals, in particular aluminium, in vacuo or under a protective gas without using fluxes, reliably and with as few limitations as possible in relation to the design of the component and the application of solder, the firmly adhering and dense oxide layers are removed at the soldering points or areas in an amalgamation process and the mercury of the amalgam layer produced is then vaporised on heating the components to soldering temperature. This produces a contamination- and oxide-free metal surface which, because of the absence of oxygen in vacuo or in the protective gas, does not reoxidise, permits a good and satisfactory wetting by the solder and, consequently, the formation of a perfect solder seam.
