Patent DE-4003790-A1 (DE)
Inventor: BUNZ GEORG
IPC: A44C5/00
Filed: 1990-02-08
Abstract: An ornamental chain consists of a core made of at least two parallel or twisted strings (11, 12, 13) and at least one metal wire (10) passing around said core, essentially punctiform contact surfaces (K) being formed between each string (11, 12, 13) and the metal wire (10).

Title: Measuring concn. for size parameters for aerosol particles - involves charging with positive ions and encasing by moving gas shield
Inventor: BERNIGAU NORBERT B DIPL ING
IPC: G01P5/08
Filed: 1990-03-15
Abstract: A stream of aerosol particles fed from one end of a cylindrical housing flows through a coaxial entry pipe (1.7) within the housing and is encased in a moving annular mass of protected gas radially injected into the entry pipe. The space between entry pipe and housing wall holds a laminator  sieve. The moving stream then passes through the interior formed by a pair of shell electrodes (2.5:2.6) with gaps for entry of positive gas ions formed by corona discharge emitted from a high voltage source (2.4). The ions charge moving aerosol particles. One electrode is coupled to a sensitive amplifier (2.8) and produces a current indicative of ion concn.  and particle dia. distribution. ADVANTAGE - Errors due to diffusion of aerosol particles are greatly reduced.

Title: Reinforced laminated sailcloth - has angled strands between layers to be passed continuously through a roller gap
Inventor: LINVILLE JAMES C
IPC: B63H9/06
Filed: 1990-03-29
Abstract: The process to develop a continuous reinforced and laminated cloth, as a sailcloth, uses two rolls of fabric where the surface of at least one is clad with an adhesive. The two materials are passed to a gap between two rollers together with reinforcement strands between the fabric layers. Before the reinforcement strands enter the roller gap zone, they are led through one or more openings in a continuous belt which moves constantly and at a given speed across the line of the two fabric layers. The two fabric layers, and the strands between them, pass continuously through the roller gap so that a laminated fabric is continuously produced and secured. The reinforcement strands are of a polymer with a high yield strength, pref. of aramide, drawn from individual bobbins mounted in a frame on a second continuous belt which travels synchronously with the first belt carrying the guide openings. The strands pass through adjustable draw tensioners before entering the guide openings. The guide belt moves at a speed so that the strands are at intervals and parallel to each other at an angle of 1-45 deg. to the longitudinal axes of the fabric layers covering them. The strand angle through the openings in the upper level of the guide belt is opposite to the angle passing through the openings in the lower belt level. The pref. strand angle is 2-20 deg. The first fabric layer is of a group of materials with a film and a fabric, at least two fabrics and a reinforcing laminated cloth as is the second fabric layer.

Title: Device for cleaning water - consists of jug with inner filter cartridge, lid is attached to handle by hinge so proper closing of lid is facilitated
Inventor: GOETZ CHRISTOPH
IPC: C02F1/00
Filed: 1990-08-23
Abstract: Device consists of a vessel which can be closed by a cover, a filter cartridge contg. a cleaning material and located in the base of the vessel, and a container with a handle for receiving the cleaned water. The vessel is placed inside this container. The vessel has a handle to which the cover is attached by a pivot. A pin is provided on the jug handle for the purpose of attaching an extension of the cover. This attachment is achieved by means of a snap-on fork on the outer end of the cover extension, and a recess is provided in the handle for the purpose of receiving this fork. The cross-section of the handle is U-shaped, and in the working position it lies against the handle of the inner container, and encloses it over a considerable part of its length. Used in cleaning water which is, for example, intended for the making of tea. The fixing of the cover to the handle allows the cover to be closed accurately without having to fit it precisely in position, and this reduces the risk of the cover falling off (due to not being properly closed) while the water is being poured out.

Title: Porch frequency phase locked loop for video demodulation - uses frequency present in porch region of video signal to generate voltage controlled oscillator tuning signal
Inventor: WEINZIERL FRANZ DIPL ING
IPC: H03L7/08
Filed: 1991-06-06
Abstract: The video signal porch phase locked loop impulse generator uses the incoming video signal in combination with a reference oscillator signal to produce gate and reset pulses for a counter gate and a 12-bit counter. The latter two units count the RF signal frequency and pass the valve via an output latch to a processor. The processor produces a digital frequency valve which is converted by a digital to analogue converter (DAC) into an analogue voltage to drive a voltage controlled oscillator (VCO). The latter converts the incoming video signal to RF as used by the counter, thus completing the feedback loop. ADVANTAGE - Obviates need to clamp video signal porch frequency after demodulation and reduces required transmission bandwidth.
