Granted: 1985-10-24
Abstract: 1. A floor heating system comprising prefabricated elements, such as system plates consisting of deep-drawn plastic plates, which are formed throughout their top surface with elevations (3) having undercuts (2a) and arranged in a predetermined grid pattern, and heat exchange pipes (5, 6) extending between said elevations, wherein the prefabricated platelike elements have been applied to heat insulating material (13) and are embedded in the floor topping when said elements have been placed, characterized in that the top portion of the system plate consists of a plastic plate (1, 2) provided with elevations (3), which are interconnected by ribs (4), which constitute a grid having nodes, wherein the undercuts (3a) of the elevations (3) and the ribs (4) serve to retain and support the pipes (5, 6), respectively, by point or line contact therewith, the elevations (12) of the plates (2) are only half-sided at two side edges at the contacting surfaces of the plates (1, 2) and are fitted over the elevations (11) of the first plates (1) to snap into their undercuts (3a) whereas the edges of the adjoining plates (1, 2) overlap in known manner to form a self-containing system of plates which are interconnected by force-transmitting joints.

Title: Optical transmission system for high-frequency digital signals
Inventor: KEIL HEINRICH DIPL ING
IPC: H04B10/50
Filed: 1982-09-17
Granted: 1987-02-05
Abstract: A desire exists in the optical transmission of optical signals to co-transmit a service channel or telemetry signals in the form of an additional low frequency signal over the light conductor, since a remote feed line or a service channel is not always installed parallel to the light conductor length. The requirement exists for the transmission of the additional signal that, in addition to a low additional expense, no disruption of the actual useful signal can occur. To this end, the control signal of a laser diode transmitter is modulated with the signal to be additionally transmitted and this light component is coupled out at the receiving side. The structure is particularly useful in optical transmission systems for very high frequency digital signals with bit rates above 100 Mbit/s.

Title: Steam bonding of solid lignocellulosic material
Inventor: STOFKO JOHN
IPC: C08L97/02
Filed: 1982-01-15
Granted: 1987-03-12
Abstract: Composite products are formed, such as of lignocellulosic particles, by bonding through the transformation of added sugars and/or starches together with lignin and/or other phenolic containing materials, with the optional presence of added catalyst, the transformation causing the composition to convert into a furan-lignin type binder in situ by heat and pressure. The bonding composition is suitably activated by contact with live steam.

Title: Method and apparatus for generating a start of combustion signal for a compression ignition engine
Inventor: BULLIS ROBERT HOWARD
IPC: F02D41/40
Filed: 1982-07-05
Granted: 1989-06-29
Abstract: The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine (10), and for using such signals to control the timing of fuel delivery to the engine. The combustion event is sensed, as by an electrostatic (230, 330) or optical (130, 430) sensor, and signal conditioning circuitry (32) provides a start-of-combustion (SOC) signal (34) which is directly and precisely indicative of the time of the onset of combustion. The sensors (130, 230) include self-cleaning capabilities (48, 248) for extended operating life on an engine. The sensors may be incorporated in the structure of a glow plug (330, 430).The SOC signal (34) is advantageously supplied to a timing control circuit (26) which delivers a timing control signal (28) to a fuel delivery device, such as the controller (16') associated with a fuel pump (16). The control circuit (26) stores (66) one or more start of combustion values (SOC<sub>.</sub>) which indicate the desired timing, relative to an engine cycle (24), for the start of combustion event as a function of speed (26) and load (27). One or more adjustment signals (ASOC) are stored (75) and applied (67,68) as a function of speed and load to adjust the desired signal (SOC<sup>*</sup>) such that the control signal (28, SOC<sub>c</sub>) is corrected for delays. The actual SOC signal (34) is compared (71) with the desired signal (66) to generate an error signal (72) which may be used to finely adjust the stored (75) ASOC signal for particular speed and load conditions.

Title: Blood pressure measurement with korotkov sound artifact information detection and rejection
Inventor: WEAVER CHARLES
IPC: A61B5/022
Filed: 1983-06-29
Granted: 1988-10-13
Abstract: The system includes an inflatable cuff which is inflatable to a pressure above systolic pressure and deflatable to a pressure below diastolic pressure. A pressure transducer connected to the inflatable cuff generates a signal which is a function of cuff pressure. A microphone picks up Korotkov sounds, and artifacts, during deflation of the cuff and electrodes attached to the subject pick up  electrocardiographic signals. The peak of the ECG R-wave is detected by R-wave peak detection techniques. Many, but not all artifacts, are removed from the microphone output by use of K-sound detection techniques. The pressure transducer output is converted to digital form for transfer to a digital computer and storage in the computer memory. The time of arrival of the peak R-wave signals and associated K-sound and artifact signals also is stored in the computer memory. RK intervals comprising the time interval between the time of arrival of R-wave signal and the associated K-sound or artifact signal are determined. Together with the associated cuff pressure, these establish several RK interval versus cuff pressure points.
