Patent SE-8403613-L (SE)
Inventor: HAMMER M
IPC: F23N5/20
Filed: 1984-07-06
Abstract: Only a programmable timing circuit is to be used for limiting glow duration and preheating in engine-independent vehicle heating systems. 
<??>The required switching time for preheating is based on a divider output which does not set the overall time. With this time which can be set at the timing circuit, the switching times of all the other divider outputs are then determined in accordance with the integrated program. The pulse for limiting the glow duration is tapped off from the divider output which sets the overall time and is conducted to a transistor. The transistor itself controls the timing range input. 
<??>If, after the start, the first L-H edge is produced which does not lead to any reaction when there is a direct connection of divider output and timing range input, the transistor is driven and an H-L edge appears at the timing range input, as a consequence of which the limiting of the glow duration is effective even after half the time resulting from the standard wiring.

Abstract: Inside the enclosing wall (1) of the electrostatic coating plant for applying dry or wet color coatings to electrically conductive surfaces of articles (2) set up in an insulated position is located an electrostatically chargeable curtain (9), the charge polarity of which is the same as that of the spraying gun (7) used for the coating operation. The article (2) set up in an insulated position is supplied with opposite polarity, which is necessary for the electrostatic coating, by an inductor arrangement (16) arranged above the article (2), the inductor arrangement (16) applying an electrostatic field produced by means of a peak inductor (19) to an electrically conducting layer (18), which is located on the rear of a casing piece (17) made of insulating material. The charge field radiated from the surface of the casing piece (17) brings the article (2) to be coated, suspended beneath the casing piece (17), to a potential at which the material particles located in the spraying jet (8) of the spraying gun ( 7) strike both the front and rear surface sections with approximately uniform distribution. The achieved electrostatic guidance of the coating material particles enables both an optimum utilization of the coating material and a speeded-up operating function of the coating plant.

Abstract: An integrated optical pressure transducer having a diaphragm fabricated from a low-loss glass is positioned at the location where pressure changes are to be measured. An optical waveguide loop formed on one surface of the diaphragm acts as a ring cavity in which the difference between the resonating frequencies varies with pressure but not with temperature. Light energy is coupled into the waveguide loop from an optical source through a tangentially located input waveguide. An output waveguide, also tangentially located, couples light energy from the waveguide loop to a broadband detector so that the changes in frequency spectrum of the resonating frequencies within the waveguide loop can be monitored.

Abstract: A fiber optic digital data transmitting system is disclosed which has the capability of transmitting and accurately reproducing digital data signals at the receiver even when the optical signal is attenuated in the fiber optic transmitting medium. A composite signal is produced at the transmitter which is the time coincident sum of the non-zero amplitude of the digital data signal to be transmitted and a time varying signal which encodes each non-zero amplitude of the digital signal and other information. The composite signal modulates an optical carrier signal which is coupled to a fiber optic transmission medium which couples the transmitter to the receiver. At the receiver, the presence of each time varying signal is detected as a non-zero amplitude of the digital signal. Circuitry is are provided in the receiver for producing a pulse in response to the detection of each time varying signal for reproducing the transmitted digital signal and for detecting any information in addition to the non-zero amplitude of the digital signal which has been encoded in the time varying signal. The present invention is compatible with existing PCM systems which utilize threshold detection.
