Abstract: A dual temperature sensing device has a twin well thermowell, for installation through a penetration in a pipe wall, and includes a head, shank and tip portions. The shank portion has a first part of substantially the same outer dimensions as the penetration; the head portion is of greater outer dimensions so as to define an annular ledge which overlies the exterior surface of the pipe wall, for welding same thereto. A pair of bores extend from the outer surface of the head portion at angularly inclined and converging relationship to closely spaced, but physically separated, positions in the tip portion. The head is counter-bored relative to the first bores, to define sockets for receiving the lower ends of pipe nipples, the upper ends of which are closed by pipe unions. Dual resistance temperature detectors are used with elongated sensors extending through the respective bores to the tip portion of the thermowell. The detectors are both electri­cally and physically separated, and, produce identical, dual temperature indicating outputs.

Abstract: A folded cascode amplifier with rail-to-rail common-mode range utilizes a fully differential input with two sets of input common source amplifier devices to allow rail-to-rail common-mode range. The first set of devices utilizes N-channel transistors (28) and (32) to provide operation in one direction and P-channel transistors (38) and (42) to allow operation in the other direction. Two common gate amplifier output legs are provided for generating a differential voltage between an output node (50) and an output node (48) in a cascode configuration. A feedback circuit is provided for maintaining node (50) at analog ground over the full common-mode range of the input voltage. The feedback circuit utilizes a current source with transistors (88) and (90) and a differentially configured set of transistors (80) and (82) to control a feedback transistor (86). The feedback transistor (86) controls the current in both of the output legs to maintain the node (50) at analog ground by receiving at one of the differential inputs the voltage on the node (50) and comparing it with analog ground on the other differential input.

Title: Optical color line scanning and imaging device having a roller drive
Inventor: CHEN PHILIP L
IPC: H04N1/00
Filed: 1988-11-23
Abstract: Material such as a document or picture of which an image is to be reproduced or transmitted, as in a facsimile device is driven by pinch rollers past a light source in a controlled synchronized manner by means of a stepping motor. As the pinch rollers are driven, successive scan line images of the document are channelled through an elongated slit in a light directing channel and through a lens and a rotatably driven color wheel onto a light sensitive device such a linear array formed by a charge-coupled device (CCD). The color wheel has light filters for the primary colors and is synchronized with the scanning. The images received by the CCD are converted thereby to electrical form and appropriately processed for transmission or local utilization. A mechanism is provided to enable the disengagement of the pinch rollers from the material being scaned to avoid damage to such material should it become jammed in the rollers.

Abstract: A digital phase comparing circuit includes: first and second input terminals (IN1, IN2); a level change detecting circuit (D1, D2) for detecting changes in levels of first and second input signals (S1, S2) applied to the first and second input terminals, respectively, and outputting first and second detection signals (S3, S4) indicating the changes in levels; and a flip-flop circuit (FF3, FF4, 11) which is set in response to an input of one of the first and second detection signals and which is reset in response to a following input of one of the first and second detection signals. The digital phase comparing circuit outputs a pair of output signals (S5, S6; S7, S8) having a pulse width corresponding to a phase difference (φ, φ1, φ2) between the first and second input signals, thereby making it convenient for a following circuit to utilize both "H" level and "L" level signals, while simplifying the process and facilitating the high degree of integration thereof.

Abstract: A hydraulically damped mounting device has two anchor parts (10,12) connected by a resilient wall (18) which applies a spring force to relative vibrations of the anchor parts (10,12). Also connected to the anchor parts (10,12) are two bellows walls (24,26) each defining a corresponding chamber (28,30) for hydraulic fluid, which chambers (28,30) are interconnected by a passageway (32). The bellows walls (24,26) deform substantially freely of spring resistance and so the volume of the corresponding chamber (28,30) can change without spring resistance. Thus there is a pumping action of fluid between the chambers (28,30), giving a damping action due to the passageway (32) and hence the spring and damping characteristics of the mount are independently selectable.

Abstract: In a circuit arrangement for matching the resonant frequency of an antenna resonant circuit (18) to the output circuit of a transmitter output stage (10) the antenna resonant circuit (18) is loosely coupled via a reactance to the trans­mitter outupt stage (10). By means of a current sensor (16) the supply direct current of the transmitter output stage (10) is detected. A tuning component (26) lying in the antenna resonant circuit (18) can be changed as regards its value by means of a control signal; the tuning component is a governing factor for the resonance frequency of the an­tenna resonant circuit (18). A comparator and control unit (36) repeatedly samples the value of the supply direct current detected by the current sensor (16). In dependence upon the result of a comparison with a respective previously sampled value it applies the control signal to the tuning component (26) to obtain a maximization of the supply direct current detected.
