Granted: 1993-02-09
Abstract: ABSTRACT OF THE DISCLOSURE       Snow lying on a road or building structure is melted and removed without sprinkling water on the snow by pumping up from a well and circulating underground water, which is contained in an underground aquifer and warmed by geothermy of the aquifer utilizing  the heat retaining function thereof, through pipe arrangement laid under the surface of the road or building structure.  The used  and  cooled  underground  water  is  returned  into another artesian well without being wasted and exposed to the atmosphere.   Underground water warmed by the solar heat and stored in the aquifer in a hot season may be preferably used in a cold snow season.  An arntifreezing liquid  may  be  filled  and  circulate  in  the  pipe arrangement to perform effective heat transfer through a heat exchanger between the antifreezing liquid and the underground water which circulates from one well to the other well.  A pipe having excellent crystal structure of the  welded  joint  portion  can  be used  for  the  pipe arrangement.

Title: Semi-automatic string trimmer head
Inventor: HAUPT EUGENE J
IPC: A01D34/416
Filed: 1989-07-14
Granted: 1991-04-30
Abstract: ABSTRACT           A string trimmer providing an incremental indexing of line when the head is stopped and started.  The preferred embodiment of the string trimmer head includes a spool member within the body member, the spool member being coaxially positioned within the body member and being rotatable therewith. The spool member includes a grooved and face with a cam channel having at least one switchback and one arcuate segment.  A connecting means attached to the body member includes a connector which runs within the cam channel.  Upon starting the rotation, the connector runs along an arcuate segment of the cam channel (permitting relative rotation between the spool member and the body member thereby indexing a length of line) until contacting a switchback stopping point.  The connector is biased to move along the switch back and resets along the switchback upon stopping of rotation.

Abstract: ABSTRACT OF THE DISCLOSURE   In  order to  connect two adjacent  elements (E1,E2) joined,  for example, onto  a satellite solar  panel, an antifriction   joint  (10)   is  used,   the  deployment kinematics  of  said joint  able to  be known  extremely accurately.  This  joint  comprises two  braces  (12,14) suitable   for  rolling  one  onto   the  other  by  two cylindrical surfaces (12a,14a).  Guiding of  rolling is ensured by  two flexible members, such as rolling plates (16,28) whose  extremities are secured to the braces and which pass  by crossing between the cylindrical surfaces (12a,14a). A  traction prestressing stored in the plates avoids   any   stray   movement  between   the  braces, especially  at the time of  deployment. The drive torque ensuring  the automatic deployment of  the joint and its end-of-travel locking  are ensured by elastic bands (36) connecting  the  two  braces  and  each  formed  of  two superimposed plates.

Abstract: Binding of a particular protein by an antibody reagent involving denaturation of the protein and use of an antibody reagent specific for binding a linear peptide epitope therein. Denaturation by chemical or physical means effectively exposes or enhances the exposure of the linear peptide epitope for binding by the antibody reagent which is preferably raised against a synthetic peptide immunogen. The technique is particularly useful in performing immunoassays for protein, in aqueous test samples. Monoclonal antibodies are also provided which are specific for the glucosylated N-terminal peptide sequence in the beta-subunit of human hemoglobin and are therefore useful in the determination of Hb Alc.

Abstract: A four-wire termination circuit has a series arrangement of a current source controlled by a transmitting arm of a four-wire line and a first resistor. This arrangement is connected in parallel to a two-wire line terminal impedance formed by a second resistor and an impedance. The terminal impedance terminates the two-wire line in reflection-free fashion. Voltages dependent upon a transmitted signal current which are equal in value but opposed in phase appear across the first and second resistors. A voltage which is dependent upon a received signal current from the two-wire line appears across the second resistor. In a receiving arm of the four-wire line, an intermediate value voltage is present which is independent of the transmitted signal in the transmitting arm.

Abstract: A CATV system uses a single single-mode optical fiber (16) for transmitting a composite optical signal (62) containing television signals in different frequency channels for a plurality of subscriber terminals (14) from a headend terminal (10) to a distribution terminal (12), and converts the transmitted signals at the distribution terminal into electrical signals for distribution to a plurality of subscriber terminals over a plurality of coaxial cables (18). The distribution terminal further receives electrical service request signals (88) from each of the plurality of subscriber terminals, and converts each received service request signal into an optical service request signal (84) for transmission to the headend terminal over the same single-mode optical fiber (16) as used from transmitting the composite optical signal. Wavelength-division multiplexer/demuitiplexers (50,70) couple the optical fiber to the headend terminal and the distribution terminal to enable bidirectlonal transmission. The subscriber terminal is responsive to a control signal transmitted to the subscriber terminal for enabling a receiver (96) therein to receive television signals transmitted to the subscriber terminal over a selected one of said different given frequency channels. The headend terminal includes a digital switch (40) that is operated in coordination with the control signals that are transmitted to the subscriber terminals for enabling reception of only selected frequency channels in the respective subscriber terminals, by frequency positioning the television signal indicated by the service request signal (66) received from a given subscriber terminal witbin the composite signal for transmission to the given subscriber terminal over the given frequency channel enabled by the control signal that is transmitted to the given subscriber terminal.

Abstract: A process for controlling the brightness (dimming) of a gas-discharge lamp (GE) which is located in a series resonant circuit (L1, C1) connected to a rectifier-inverter combination (10, 20), by varying the frequency (f) and the duty ratio (D, d) of the output alternating variable (uw) generated by the inverter and supplied to the gas-discharge lamp and to the series-resonant circuit (X; L1, C1, GE). The lamp (GE) is operated in a frequency range in which the dependency of the lamp power (Pab) on the frequency (f) of the output alternating variable (uw) can be represented by the duty ratio (D, d) as a parameter as a family of characteristic curves (K1, K2, K3, ...), each of which runs in the manner of a bell-shaped curve starting from a maximum value and reducing to form a point of inversion. The maximum value of the individual characteristic curves (K1, K2, K3, ...) of the family becomes smaller as the duty ratio (d1, d2, d3, ...) associated with these characteristic curves (K1, K2, K3, ...) as a parameter becomes smaller. The process is intended to be designed such that the brightness of a gas-discharge lamp can be varied in a stable manner without flicker. This is achieved in that the frequency (f) and the duty ratio (D, d) are in each case selected such that the operating point (B1, B2, B3, ...), with at least two characteristic curves selected or available for a specific lamp power (Pab), in each case coming to rest on that characteristic curve which has the lower gradient at this lamp power (brightness). <IMAGE>

Abstract: System for improving performance of spark ignition, internal combustion engines using fuels such as liquified petroleum gas (LP-gas), which have conventionally been stored as a liquid and delivered to the engine as a vapor. This system stores such fuels as liquids (10) and delivers the fuel to the engine inlet air stream as a liquid. The absorption of heat by the vaporizing fuel lowers engine inlet air temperature, increasing its density and permitting more fuel to be burned in each cycle. Vaporizing heat in a pilot line (17) provides the cooling to the liquid fuel in the main fuel line (20) and provides fuel to maintain the engine idling. A member (27) slides within a fuel delivery chamber (25) for covering or uncovering a series of orifices (26) through which the liquid fuel passes into the inlet air stream of the engine.
