Patent EP-0288951-A2 (EP)
Inventor: KLEMM GERHARD
IPC: B29C61/00
Filed: 1988-04-25
Abstract: The method and apparatus are intended preferably for plastic sheets processed by means of contact shrinkage and subsequent winding. The intention here is for a suspending and resting area for the sheet to be provided between the shrinking area and the winding area. This is achieved by providing between the shrinking roll or rolls and the winding roll a distance in the horizontal direction between two sheet- guiding means, such as tubes, rollers, deflecting devices or the like, to form a free-falling sheet loop. In this arrangement, a sheet- guiding means at the last shrinking roll releases the sheet, running downwards, and the sheet-guiding means transporting the sheet further receives the sheet by coming up from below. The sheet can "work" freely in this area and is wound up in such a suspended fashion. <IMAGE>

Abstract: Process for the stepwise changing of the gears of an automatic transmission of a motor vehicle, whose transmission (2) is driven via a hydrodynamic torque converter (4), or a dry-friction clutch (3), short-circuiting the latter, and is controlled by means of an electrohydraulic valve system (12). According to the invention, a speed signal and an electrical engine speed signal are generated continuously from the speed of a component or pair of components driven by the transmission (2). The speed signal and the engine speed signal are used to form a slip signal proportional to the value of the slip of the hydrodynamic torque converter (4), which signal is compared with a change-up slip signal representing the constant change-up slip value, and a change-down slip signal, representing the constant change-down slip value. The engine speed signal or the speed signal is compared with a change-up speed signal, representing the constant change-up speed value, and with a change-down speed signal, representing the constant change-down speed value. If the selected speed signal increases above the change-up speed signal and the slip signal decreases below the change-up slip signal, a change-up command signal is supplied to the electrohydraulic valve system to change the transmission (2) into a higher gear, while, on the other hand, if the selected speed signal is less than the change-down speed signal, or the slip signal increases above the change-down slip signal, a change-down command signal is supplied to the electromagnetic valve system (12), to change the transmission into a lower gear.

Abstract: The demodulator is basically constituted by mixers (2) and (3), low pass filters (LPFs) (4) and (5), A/D converters (6) and (7), a clock recovery circuit (8), a phase error detec­ting circuit (9), a digital-to-analog (D/A) converter (10), a loop filter (11), a voltage adder (12), a sweep controller (13′), a voltage controlled oscillator (VCO) (14), a 90° phase shifter (15), and an error correction/synchronization decision circuit (16). Connected between the sweep control­ler (13′) and the D/A converter (10) are a high pass filter (HPF) (101), a detector (102), and a comparator (103). The error correction/synchronization decision circuit (16) de­termines whether synchronization has been established, whereupon the sweep controller (13′) stops generating a sweep signal and holds its output at a predetermined level. In the event of false synchronization, a beat component is superposed on the output (error voltage) of the D/A conver­ter (10). The detector (102) detects the input beat compo­nent signal. Receiving an output of the detector (102), the comparator (103) compares the output of the detector (102) with a predetermined reference voltage. When the output of the detector (102) is higher than the reference voltage, the comparator (103) feeds the previously mentioned control sig­nal to the sweep controller (13′) . As a result, the sweep controller (13′) resumes the generation of a sweep signal, i.e., the false synchronization is cancelled.

Abstract: A microphotometric determination of organic chemical material, in particular of hydrocarbons, can be achieved with relatively simple means with a microscope photometer by measuring the absorption owing to CH oscillations at 1600 to 1800 nm or NH oscillations at 1400 to 1600 nm, which although relatively weak can be used as a basis for measurement on account of a high signal-to-noise ratio. A microscope photometer suitable for measuring comprises optics transmitting appropriately in the near infrared range of  lambda  > 1000 nm (NIR) and a photometric measuring device with low-noise NIR detector as well as a light source of high power density in the NIR. The monochromator is preferably formed by an interference filter having peak transmission perpendicularly to the path of rays at about 1800 nm, about 2000 nm or about 1600 nm as well as an average bandwidth of </= 20 nm, in particular 10 nm, the angle of which in the path of rays can be altered between 0 and 90 DEG , in particular by means of a 5-phase stepping motor having a stepping sequence of about 1000 steps/revolution. Sensitive measurement is accomplished by an intensity modulation by means of a light chopper or a wavelength modulation with the aid of the interference filter together with a detector operated by the lock-in technique. <IMAGE>

Abstract: A satellite communications system employs separate subsystems for broadcast and point-to-point two-way communcations using the same assigned frequency band and employs an antenna system which uses a common reflector (12). The point-to-point subsystem achieves increased communication capacity through the reuse of the assigned frequency band over multiple, contiguous zones (32, 34, 36, 38) covering the area of the earth to be serviced. Small aperture terminals in the zones are serviced by a plurality of high-gain downlink fan beams (29) steered in the east-west direction by frequency address. A special beam-forming network (98) provides in conjunction with an array antenna (20) the multiple zone frequency address function. The satellite (10) employs a filter interconnection matrix (90) for connecting earth terminals in different zones to permit multiple reuse of the entire band of assigned frequencies. A single pool of solid-state transmitters allows rain-disadvantaged users to be assigned higher than normal power at minimum cost and geographically disperses the transmitter intermodulation products. In an alternate embodiment, the satellite (200) employs direct radiating array antennas (202, 204) for reception and transmission. The system (200) utilizes hybrid-coupled dual amplifiers (251) to reduce amplifier production costs. In another embodiment, both point-to-point and broadcast services are available on a single polarization by allocating one-half of the frequency spectrum to each service and by using separate direct radiating arrays from horizontal and vertical polarization for both reception (235, 236) and transmission (237, 238). The frequency spectrum is reused in each of the contiguous receive zones (220, 222, 224, 226) and the transmit zones (228, 230, 232, 234) because sufficient spatial isolation is achieved by subdividing the receive zones in two halves (220a, 220b, 222a, 222b, 224a, 224b, 226a, 226b), and by using one-half of the frequency spectrum in each subdivided zone.

Abstract: A knock detection system for an internal combustion engine, comprising an input (IN) for receiving a signal from a vibration sensing transducer, and a bandpass filters I2 and I4 connected to the input. Bandpass filter I2 passes a band of frequencies containing the characteristic knock frequency, so that it passes the knock-representing com­ponent together with noise. Bandpass filter I4 passes an adjacent band of frequencies having substantially no knock component content but a noise component corresponding to that passed by filter I2. The outputs of the two bandpass filters I2,I4 are referenced to each other (e.g. by rectify­ing on opposite polarities at I3,I5 and summing at J) to cancel out the noise and provide signal which represents the known component in the output from the vibration-­sensing transducer.

Abstract: An interface between a product planning conceptual design tool and a CAD/CAM environment allows an indented bill of materials to be imported to the CAD/CAM environment while retaining the characteristics as a primitive text file. The conceptual design tool uses a sketch sheet approach on a computer display to enter the functional design of a new or modified product, thereby encouraging the designer to use a top down approach to the design process. The user keys in item information, and the system automatically draws a hierarchical tree structure on the computer display. The system then automatically generates an indented bill of materials which is stored in a graphics standard file that retains the character of text primitives. From this file an image of the bill of materials can be displayed in the CAD/CAM environment. The designer can use this image as an aid in the design process. Item names and numbers can be copied from the displayed bill of materials to the CAD/CAM image. The bill of materials can also be edited in the CAD/CAM environment and the edited bill of materials can then be reconstructed in the conceptual design tool for use in the continuing design and planning process.
