Patent DE-3223904-A1 (DE)
Title: Filter and demodulation circuit
Inventor: HANSEN JENS DIPL ING
IPC: H04B1/16
Filed: 1982-06-26
Abstract: A filter and demodulation circuit is proposed which, when used in a radio-frequency receiver, produces an increase in the sensitivity of the receiver. In the filter and demodulation circuit, the intermediate frequency is divided into at least two parallel channels (11, 12) at the input (10). Each channel contains a series circuit comprising a mixing and oscillator circuit (13, 15; 14, 16), a controllable IF filter (17, 18), a demodulator (19, 20) and a high-pass filter (21) or low-pass filter (22). One transmission channel essentially transmits the modulation frequencies of a first frequency range only and the other transmission channel transmits the modulation frequencies of a second frequency range. The AF voltage at the output of each transmission channel re-adjusts the IF filter of this channel and the oscillator circuit of the mixing and oscillator circuit of the other channel. <IMAGE>
Patent DE-3227053-A1 (DE)
Title: Bumper bar with metal support profile injection-coated with plastic
Inventor: MAYER GERT
IPC: B60R13/04
Filed: 1982-07-20
Abstract: The invention relates to a metal support profile coated with PVC or another plastic by injection moulding, which is preferably used in the automobile construction industry. In this kind of bumper bar, which is thinly coated with plastic, the metal flank area, which is supported free of plastic, deforms on account of the high injection pressure in such a manner that blemishes occur in the visible region, the thin-walled metal profile is supported by the mould at some points and thus cannot always be completely injection-coated. According to the invention the object is achieved in that openings in the form of punched holes or the like, having a smaller cross-section than the thickness of the plastics wall, are provided at regular or irregular intervals in the metal profile. The resulting pressure equalising of the injection medium ensures uniform coating and thus a smooth surface of a bumper bar manufactured in this manner.

Patent DE-3227967-A1 (DE)
Title: Spatial, beam-like supporting element, preferably roof element, made of reinforced concrete and method for manufacturing the same
IPC: E04C3/20
Filed: 1982-07-27
Abstract: The supporting element (1) has a closed cross-section with lateral longitudinal webs (2), a base plate (3) and a plane cover plate (4) which projects beyond the longitudinal webs (2) at the longitudinal edges. The individual components of the supporting element are extremely thin-walled. They consist of a concrete mix of small particle sizes and are reinforced by a reinforcement which is arranged in a position substantially in the median plane of the components in question and consists of close-meshed, corrosion-protected wire grating. As a result of this construction and arrangement of the reinforcement and the particular concrete formulation, extremely thin walls are made possible; as a result of the special shape of the hollow-box cross-section comprising wall discs and plates, a very high rigidity is achieved, so that in a supporting element having a plane roof surface a maximum supporting capacity is achieved with a minimum of concrete and steel. <IMAGE>

Patent DE-3235131-A1 (DE)
Title: Saw-tooth grinding machine
Inventor: VOLLMER ERWIN HERMANN
IPC: B23Q11/10
Filed: 1982-09-23
Abstract: In known saw-tooth grinding machines, circular saw blades are slipped onto horizontal mounting arbors. The tooth lying furthest to the side on a horizontal blade diameter is ground in each case. The supporting elements of the grinding head project forward beyond the plane of the saw blade, which has to be taken into account when arranging a protective housing. The problem arises of facilitating the mounting of heavy saw blades, of enabling the grinding head elements to be shifted back in order to also shift back the front wall of a protective housing, and finally of additionally making the same machine suitable for grinding the teeth of saw bands. The solution is to arrange the mounting arbor for circular saw blades at an angle; that is, the saw blades are not mounted vertically but inclined. The top part of the machine is then inclined in a desk shape and the grinding head elements are shifted back relative to the front face of the machine. The machine is conveniently set up for the grinding of the in each case topmost tooth of the blade mounted in an inclined position, and an attachment grinding the face and the back of each tooth with the same single grinding wheel is advantageously used for the grinding. With additional elements, band material can also be mounted in such a way that in each case a tooth of the band is ground in the same position of the machine as the topmost tooth of a circular saw blade. <IMAGE>
