Abstract: The invention relates to an apparatus for the internal induction heating of cylinder liners (2) of combustion engines to the critical transformation temperature for the purpose of hardening the said liners. The object is a thin-layer surface hardening with self-quenching, only individual strips being covered at intervals in intermittent working. The apparatus is operated at relatively high alternating current frequencies in the range between 400 and 500 kHz and at relative high energy densities in the range in excess of 5 kW/cm<2 >. For this it is necessary to consistently bring the inductive loop (6) into a working position relative to the inner surface of the cylinder liner. In order to ensure this, the induction head (3) is provided with an alignment device (8), which is designed as an expandable open-centre cage, which is provided on the outside with clamping bars, clamping knobs or clamping shells (8), which can be applied play-free under force to the inner surface of the cylinder liner (2). Using these clamping shells, the inductive loop (6) is also radially displaced and brought into the working position. Heating and hardening is performed only at a standstill, that is with the inductive head (3) in the clamped and precisely aligned state, whereas after detaching the clamping shells and the inductive loops the appliance can be shifted on one graduation interval of the hardness bands or a full multiple of this. …<IMAGE>…

Abstract: A voltage-controlled oscillator according to the present invention comprises: a transistor (5), where the drain electrode (D) is grounded, the gate electrode (G) is connected to a resonator (3) whose resonant frequency is adjustable according to a voltage applied to a voltage-dependent capacitance diode (D₁) electromagnetically coupled with the resonator (3), an output signal is output from the source electrode (S); a resistor connected (R₂) in gate bias circuit or source voltage supply circuit for detecting a low-frequency noise component generated in the transistor (5), where the detected low-frequency noise component is amplified and fed back to the voltage-dependent capacitance (D₁) so as to cancel a phase-noise component generated in the voltage-controlled oscillator. The above-descried voltage-controlled oscillator may be further provided with a reference crystal oscillator to which the voltage-controlled oscillator is phase-locked. Thus, a microwave voltage-controlled oscillator excellent in phase-noise characteristics of the oscillated frequency is accomplished though there is employed a GaAs FET which is not good in a low-frequency noise characteristic.

Abstract: A multi-bit latch transceiver is designed to meet the IEEE 1194.1 standard for backplane transceiver logic as specified in the IEEE 896.2 Futurebus+ specification. The latch transceiver features support for live insertion, low skew, controlled rise/fall time (2ns-5ns) and glitch free power-up/down protection. The transceiver utilizes on-chip latches and a built-in bandgap reference that provides very accurate thresholds. Unique slave stage logic in the transceiver's driver stage provides preset input conditions to the slave latch such that data is instantly clocked to the driver output when the driver is enabled, thus reducing propagation delay.

Abstract: A break in the enclosure (24) of an electrochemical sensor, such as a pH sensor, is detected by including in the enclosure a set of elements (12, 18) which are spaced apart from each other and which are made of metals having dissimilar electrical potential and reactive characteristics. When moisture enters through the broken enclosure (24), an electrical potential difference is created between the elements (12, 18) which can be detected by a voltmeter. One (12) of the elements is advantageously made of zinc and the other (18) is advantageously made of silver or silver chloride coated silver. The elements (12, 18) in the form of ribbons or wires within the enclosure (24) may simply be portions of the leads connected to sensor sense (10) and reference (22) electrodes of the sensor. A salt may be included in the enclosure (24) to produce an electrolyte when moisture enters the enclosure (24).

Abstract: Groups of amorphous steel strips, cut to appropriate length from a composite strip, are stacked in longitudinally-staggered relationship to form packets. The groups are made up by a process that comprises a pre-spooling operation that results in the strips and groups in each packet adhering together, even though dry. The individual packets are fed successively into a belt nester that includes a rotatable arbor and wrapping means that wraps the packets in superposed relationship about the arbor as the arbor rotates, thereby building up a hollow core form. The above-described adhesive effect precludes the strips and groups from shifting longitudinally while the packets are being wrapped about the arbor.

Abstract: A flow loading unloader valve (36) wherein the operating force for moving the valve (36) from the unloaded condition to the loaded condition is supplied by the flow through the valve (36) itself. The valve (36), which may be interposed between a fluid supply (24) and a high pressure load (26), comprises a valve body (38), having an inlet (40), a working outlet (42), a bypass outlet (44), and a valve operator (48), which may include a spool (49), that controls the direction of flow through the body (38). Movement of the valve operator (48) to change the valve (36) from the unloaded condition to the loaded condition is accomplished by applying the differential pressure created by the flow of fluid from the inlet (40) to the bypass outlet (44) to the piston ends. As the pressure increases as a result of increased flow resistance through the valve (36), the valve operator (48) moves from an unloaded to a loaded position, terminating flow to the bypass port (44) and resulting in high pressure flow to the working outlet (42).

Abstract: Disclosed is a container, made by folding, with fold-in flaps, for packaging food. The container can be recycled economically, i.e. with a profit. The material consists of a metal sheet coated with a plastics skin which, when the metal is recovered, produces no residual matter or pollutants. The edges of the containers are welded to each other by the plastics coating. After bending open the flaps, the container can be easily laid flat by hand (thus reducing its volume) without it springing back and used containers can be collected in compact form in a recycling container and transported in the recycling container to the recycling facility where the metal is recovered by melting.

Date Feb. 6, 1992.A rim for a spoked bicycle rear wheel has rim holes laterally displaced by an amount (E) from an axis passing through the center of the cross-section of the rim. Such a rim can be subject to undesired tilting under stress imposed by spokes connected between the rim and the wheel hub and placed under tension. The rim side containing the spoke nipples is more highly loaded. To bring about balance of the tensions on both rim sides, the rim cross-section has an asymmetrical shape so that there is more rim material on the more highly loaded side and so that that side is also stiffer. The compressive forces in the rim material are better balanced, making it possible to use less expensive, conventional materials.
