Abstract: A hand tool has a handgrip attached to a ground-piercing probe, which is manually insertable in the soil. The probe has a chamber in which at least one inductor is positioned and connected to metal detection circuitry. The preferred circuitry has a pulse generator applying current pulses to an inductor for inducing eddy currents in a buried target object. After the pulse terminates, the decaying coil voltage is sampled at different times to detect both the presence and range of the object, as well as the type of metal in the object. An asymmetric magnetic field pattern about the probe is aligned with a direction pointing indicium on the handgrip and provides directional sensitivity. The coil voltage samples are applied to signaling circuitry, which provides an audible signal which is a series of bursts of an audio tone. The pitch of the audio tone signals the presence, range and bearing of the buried metal object, while the pulse rate of the bursts signals the metal type.

Abstract: An arrangement for filing and retrieving data of a plurality of mutually remote data sources which are connected to a remote central file-storage system by a public, wide-area transmission network. Mutually separable storage fields are maintained in the central file-storage system by allocating separate storage fields to the data of each of the remote data sources by a user filter coupled to the file storage system to ensure that every user can transfer in the central file system only in his field. An access authorization code transmitted from a remote data source is compared to an access code stored in the file-storage system to permit access by a remote data source to the separate storage fields allocated to the data source seeking access.

Abstract: A gas bearing structure including a cylindrical core and a cylindrical sleeve. The core has a radially outwardly facing surface with longitudinal and circumferential grooves formed thereon. The sleeve has a radially inwardly facing surface that sealingly abuts the outer core surface. The inwardly facing sleeve surface bridges over the grooves, defining fluid, preferably gas, flow paths within each groove. The gas flow paths permit gas to flow from the workspace to radial passages formed through the sleeve sidewall, thereby forming a gas bearing.

Abstract: A voltage regulator protecting both the regulator and the electrical system. A flyback diode is protected by an autoprotected MOSFET in series with the flyback diode and controlling it by a drive circuit connected to the vehicle ignition switch. Protection against overcurrent is provided by a resettable fuse, having a thermal protection circuit, in series with the power switch. A relay is in series with the resettable fuse. The controlled switch is controlled by the output of a voltage detector. A latching circuit holds it open as long as the circuit remains connected to the battery. Overvoltage protection is provided by a voltage detector which opens the relay if the battery voltage exceeds a pre-selected voltage. To accommodate lead-acid and maintenance-free batteries, the regulator has two input ignition terminals one of which controls the set point voltage. The resettable fuse is physically mounted in thermal connection to the power switch which switches the field.

Abstract: The present invention relates to a method for making a shielded automobile component and the shielded automobile component itself. The component includes a composite formed of a metal sheet which includes protrusions which extend from a surface of the metal sheet and a blow-molded thermoplastic layer formed around the protrusions which fixes the blow-molded layer to the metal sheet during the molding process. The protrusions on the metal sheet define plain polygonal areas which are free of protrusions.

Abstract: This invention relates to source-coupled logic (SCL) which is a functional derivative of emitter-coupled logic (ECL). ECL is widely recognized as having the characteristics of high speed (low propagation delay) and low power supply noise generation. The SCL of the prior art succeeds at maintaining and improving the low noise characteristics of this architecture but does not fulfill the promise of high speed that one would expect from a current-mode logic. In addition, it uses a differential form of logic that is not as flexible and easy-to-use as a reference controlled or “single-ended” logic. The SCL disclosed here has the desired high speed properties and maintains the ease of use that is a property of reference controlled ECL. In addition, the reference controlled SCL of this invention provides new capabilities that make it even more flexible than ECL in generating logical switching functions.

Abstract: A hydrocarbon capturing device includes a retainer that is inserted into the end of an outlet pipe in a storm sewer catch basin. The retainer includes a ring that expands under a bias against the inner surface of the outlet pipe and radially extending fingers mounted to the ring that prevent insertion of the ring into the pipe too far. Two hooks are mounted to the retainer near the upper side of the outlet pipe to fasten one end of a hydrophobic, hydrocarbon-absorbing fabric sheet to the retainer. The opposite end of the sheet extends into the passageway of the outlet pipe, thereby floating atop any water that flows through the pipe during and after a rainfall or snowfall.

Abstract: A stabilized lime slurry for treatment of biological solids in sewage. The composition preferably includes 30-36% calcium hydroxide, 10-16% potassium hydroxide, 2-4% potassium chloride, 2-4% magnesium hydroxide, all on a dry basis, and the balance in water. This composition raises the pH rapidly for destroying pathogens, is sufficiently concentrated for economically feasible transportation, and reduces the cost, difficulties and dangers of treating sewage with a lime based composition while providing a resulting product from the sewage treatment process which can be spread upon agricultural soil in a manner which improves soil fertility without introducing undesirable or contaminating materials into the soil.

Abstract: In a free piston machine, a coil is mounted to its housing and magnetically linked to a permanent magnet or electromagnet on its piston member to form a linear motor. The coil and magnet are either added to embody the invention or are part of an AC linear alternator or AC linear motor which are a part of the free piston machine. A source of DC electrical current and a switch for connecting the DC source to the coil supply DC current to the coil when the switch is closed so that the coil and magnet temporarily operate as a DC linear motor until the piston is adequately centered for start-up without collision. The DC source voltage is temporarily applied to the coil to move the piston away from an end wall of the cylinder. This is accomplished by applying the DC current to the coil for a predetermined time interval, or by sensing when the piston has reached an adequately centered position.

Abstract: A free piston internal combustion engine having improved valve timing. A pair of oppositely disposed combustion chamber passageways extending between the combustion chamber and the earth's atmosphere, each have a combustion chamber valve for controlling the passage of gas through the passageways. The combustion chamber valves are essentially simultaneously opened and closed to permit independent variation and control of the compression ratio, expansion ratio, and stroke of the engine. When the valves are opened, the combustion chamber is purged or supercharged with combustion supporting air, and closed to initiate compression. Variable control of the piston positions at which the valves are opened and closed permits the engine to operate at a high efficiency over a broad range of power output loading conditions.
