Patent DE-4207492-A1 (DE)
Title: Phase control circuit for clock signal regeneration from data signal - has two logic links with inputs fed with data signal and (non)inverted clock signal
Inventor: FISCHER JENS
IPC: H04L7/033
Filed: 1992-03-10
Abstract: The circuit contains a phase comparator (9) of logic link circuits (21, 22). To the inputs of the latter is supplied a data signal, prepared by a flank detector (7), and a clock signal from a VCO (10). Output signals of the logic link circuits are passed through a narrow band loop filter (23-28) and supplied to inputs of an amplifier assembly (29-34) with Pi transmission characteristic. The amplifier assembly contains an offset. At one input of the amplifier assembly is coupled a comparator (35) with a hysteresis, which couples a filter output signal with fixed potential via a change-over switch (36). The two logic links are pref. NOR-gates, each with two inputs. USE/ADVANTAGE - For transmission of NRZ data signals, with reliable operation.

Title: Heating circuit for flats - comprises boiler and exhaust flue with extract fan at top and one or more capped off branches in rooms
Inventor: VETTER RICHARD
IPC: F24F13/02
Filed: 1992-05-05
Abstract: The extract fan (8) at the top of the gas flue (7) keeps it below atmospheric pressure, and the branches (13) are sealed off at their ends by caps (14) which can only be opened by vacuum or low pressure in the flue and by the boiler not working. The caps are kept closed by gravity or spring closure. The rooms have underfloor heating by means of the exhaust gas flowing through coils of pipe (12) in the floor. In summer months the rooms are kept cool by fresh air sucked into the flue branches and underfloor pipes by the radial fan. ADVANTAGE - Danger from exhaust fumes is avoided by maintaining low pressure or vacuum in the flue.

Patent DE-4217108-A1 (DE)
Inventor: HARVEY STEPHEN CHARLES
IPC: B60G17/019
Filed: 1992-05-22
Abstract: For measuring the inductance of a variable inductor (10), a capacitor (C1) is charged to a predetermined voltage VB and connected Q1 into a parallel passive oscillator circuit with the inductor, and the damped resonant frequency of the circuit is measured M to enable calculation of the inductance. The clamped resonant frequency is determined by timing the first quarter-cycle of clamped oscillation. In a position sensor using a variable inductor, a core (31) is moved into a coil (30) by a cam (32) on a spindle (33) whose rotary position is determined by a rotary linkage arrangement (Figure 4 not shown) sensitive to the vertical position of a vertically movable member (26). The sensor output may be used in an anti-lock brake system as in Figure 5 (not shown). <IMAGE>

Title: On=line offset printing colour applicator control system - uses calculated colour values over part of printed sheet to derive integrated comparison level
Inventor: HUEBLER ARVED CARL DR
IPC: B41F33/00
Filed: 1992-11-02
Abstract: The offset printing system uses print rollers (1 to 4) to apply black, cyan, magenta and yellow colour to a paper run (5). Each roller has a colour applicator control unit (6, 7, 8, 9) and measurement unit (10, 11, 12, 13). Before the paper path passes the first roller, a measurement unit measures the optical density of a sheet in a measurement zone (15) over the sheet length. After passing a print roller (1), the optical density is measured by another measurement unit (10) in the same way. A difference value is formed and compared with a value calculated from the print raster colour values over the measurement area. A correction signal is generated to regulate the colour applicator (6). USE/ADVANTAGE - Offset printing colour match control by monitoring actual print area rather than by use of test strips.

Patent DE-4303114-A1 (DE)
Title: Drive device for a wiper device
Inventor: EPPLE ANTON
IPC: B60S1/24
Filed: 1993-02-04
Abstract: A known drive device has a drive crank and a drive rod which engages with a transmission lever which sits, in a manner such that it can rotate, on the wiper shaft. This transmission lever is coupled, via a clip, in such a manner to a rocker, which sits in a rotationally fixed manner on the wiper shaft, that for securing under a snow load it is possible for the lever to be deflected relative to the rocker in the vicinity of the reversal points of the wiping movement. The novel drive device provides a transmission lever (3) which is coupled directly to the rocker (4) and with a slotted guide link (17, 18) can rotate relative to the rocker. The slotted guide link (17), which is closed at least on one side and is in the shape of an elongated hole, makes it possible for a central region of the actual wiped area (7) to be wiped, even when a spring element (13), which defines the normal position, fails. Use for wiper systems in motor vehicles. <IMAGE>
Patent DE-4304127-A1 (DE)
Title: Hose reel
Inventor: SCHMIDTNER LORENZ
IPC: B65H75/40
Filed: 1993-02-11
Abstract: The large ground wheels fastened in a basic frame move the hose reel running in the same direction and, by means of some gearwheels, the horizontally running hose-guide roller, each by 26 millimetres for every complete revolution of the hose reel, so that the new hose winding comes to rest in each case closely, but neatly next to the last hose winding. The hose does not need to be touched by hand either during unrolling or during rolling-up, particularly not on the ground, so that there is no possibility of becoming wet and dirty. A valve rotatable all-round is located between the spray piece attached to the hose reel on the outside and the rolled hose, so that the spray piece can always be held in the desired direction even while the appliance is running and during spraying. A motor can move the appliance backwards and forwards and thereby wind up the hose and lay it out on the garden path, even when there are many narrow bends, so as to take care of the plants and without the need for any effort. The soiling of the person and the repeated time-consuming stooping which are unavoidable where the conventional appliances are concerned are also avoided.

Title: Sealing strip with rhomboidal attachment - which is filled with adhesive which can be melted by heat applied by internal heating element.
Inventor: WEZSTEIN EGON
IPC: B60J10/24
Filed: 1993-02-23
Abstract: A sealing strip has a hollow D-shaped cross-section (5) with an attached rhomboidal section consisting of an upper part (7) and a lower part (6). The rhomboidal section is partly filled with an adhesive which can be melted by heating. The heat to melt the adhesive is supplied by an electrical heating element (13) which is formed from fuse wire. The sealing strip is installed after the adhesive has been melted so that the rhomboidal section can be easily compressed to fit in the gap. When the adhesive has solidified the walls of the rhomboidal section are still capable of being elastically deformed. USE/ADVANTAGE - Sealing strip for sliding roof of a motor vehicle. The width of the rhomboidal section can be adjusted to suit variations in the width of the gap by the sliding panel and fixed roof.

Title: Heater/radiator (cooler) seal
Inventor: HEFEL JUERG
IPC: F28F9/04
Filed: 1993-06-08
Abstract: The present invention relates to a seal between a feed pipe and a heating element of a heater through which water flows.
