Title: Web bump detection - uses defined and structured light beam over surface of moving web to locate local surface bumps
Inventor: SEIBERT FRANK
IPC: G01B11/30
Filed: 1991-04-18
Abstract: To detect local bumps, esp. as faults, on a moving material web esp. as carrier material for photographic or reprographic coatings but also for roller surfaces and fabric piecegoods and the like, a defined radiated bundle (13) is aligned directly over the surface of the web (2), in a spectrum range between ultra-violet and infra-red light with wavelength (1.3 X 10 power2 to 3.4 X 10 power6 Angstrom The light beam is directed across the direction of material (2) travel, to be received by a light-sensitive sensor (4) at the opposite side of th web path. The sensor (4) generates a signal in a sequence to show at least partial coverage of the light beam (13) by a bump projecting from the surface of the web (2) passing through. A light source (1) on one side of the material (2) path transmits a light beam (13) to the light sensor (4) on the other side of the path, directly over the surface of the web (2). The web (2) passes over a roller (3) or sliding path as an underlay for the web (2) between the light source (1) and sensor (4) under the light beam (13). A diaphragm (6) near the sensor (4) defines the height and/or width of the incoming light beam (13) at the height (H) of anticipated bumps. ADVANTAGE - The method gives a quantitative and qualitative measurement of local bumps and also where they occur.

Filed: 1991-05-14
Abstract: A friction false-twist texturising machine has a threading device operated by hand. The manipulated levers have spring loaded blades to insert the thread into the machine without contacting the rotary discs. Pref., the friction discs have drives leaving a central area in which the thread passes in order to be texturised with a false-twist. The levers are operated manually, pressed together against the spring, so that the thread which lies on the surface is lifted into the process area, without stopping the rotation of the discs. A further spring retains the levers in position. The surface may be chromed or made of ceramic to withstand the passage of the thread. ADVANTAGE - The machine is threaded quickly and reliably.

Title: Sensor equipment for rail contact - has compactor halting input of clock pulses to counter when voltage from counter resistor network reaches certain value
Inventor: GRAF RUEDIGER
IPC: H03K17/95
Filed: 1991-09-26
Abstract: The sensor equipment includes an oscillator (OSZ) whose output is fed through a network (R4,C4) to a comparator (SK). The other comparator input is provided with a reference voltage (UR) derived from the output resistor network (RN) of a counter (Z). The comparator outputs the sensor signal.

Title: Adjusting printing pressure in printing machine - involves separate adjustment for plate cylinder and blanket cylinder
Inventor: JENTZSCH ARNDT
IPC: B41F13/34
Filed: 1991-12-23
Abstract: The printing machine has a printing cylinder (2), a blanket cylinder (3) and a plate cylinder (4).

Filed: 1992-01-30
Abstract: A built-in sink has at least one basin having first surface areas that are subjected to strong stresses during use, such as the bottom of the basin, and second surface areas that are less strongly stressed during use, such as the sidewalls of the basin.

IPC: F23N5/18
Filed: 1992-02-15
Abstract: 2.1 In known burner systems, simple modulation of the burner output, reliable fuel metering, fine atomization and Lambda control cannot be achieved. In addition, impure exhaust gas is formed in open-loop operation. 2.2 In the burner system according to the invention, the air flow rate is measured in a measuring section, the measurement variable of which is an electric signal which is emitted by a pressure sensor (27) or by a hot-wire air mass flow meter (2) and is processed in an electronic control unit (13) to give a control signal for an electric servomotor (15) which controls and regulates the fuel flow through a calibrating nozzle (16, 30). 2.3 The new burner system is distinguished by its simple construction and is suitable for modulating the burner output within a wide range and, inter alia, also for a method of compensating for changes in fuel viscosity. <IMAGE>

Inventor: STRAUBEL MAX DR ING DR
IPC: F02D41/40
Filed: 1992-03-05
Abstract: The fuel injection pump has a pump piston (11) driven by a cam drive (13, 14) and an injection timing adjusting device (33) for the drive. The adjusting device comprises a piston (37) displaceable in a cylinder against a spring bias (40) by speed-dependent pressure fuel supplied to a chamber (41) from which extends a relief line (44) controlled by a solenoid valve (45). A sensor (48) is provided for ascertaining the actual instant of injection by detecting a variable proportional to the movement of the adjusting piston (37) occurring during each injection operation. The sensor (48) is connected to a control device (46) in which the actual instant of injection is compared with the optimum instant of injection, and the solenoid valve (45) is triggered in the required manner. The movement of the adjusting piston (37) is limited by a stop (52) in the direction to retard the instant of injection. Since the sensor (48) is unable to produce a signal when the piston is against the stop, the control device (46) also acts to move away from the stop (52). <IMAGE>
