Title: Half wave demodulation circuit
Inventor: DICKEY JOHN ALVIN
IPC: H02M7/21
Filed: 1985-05-07
Abstract: An electronic circuit for converting an AC voltage input signal to a DC voltage output signal utilises a square wave reference signal (31) for regulating a field-effect transistor (38) to switch on the input signal (30) for a half period, and to switch off the input signal for a half period, whereby ripple current flows through a first filter (43, 45, 47) coupled to the transistor for only a half period, with a steady discharge current through the first filter for the other half period" thereby reducing ripple. A second filter (46, 49) coupled to the first filter (43, 45, 47) and an operational amplifier (51) further diminish ripple.

Abstract: In a method of specimen treatment preparatory to conducting an immunoassay, a microbial protein is solubilized by a detergent at elevated temperature and in the presence of an alkali or alkaline earth metal ion. At elevated temperatures, the detergent is soluble. However, at lower temperatures, the presence of the metal ion renders the detergent insoluble so that it is prevented from interacting in the immunoassay procedure. A specific application is in the solubilization of the principal outer membrane protein of Chlamydia trachomatis.

Abstract: A linear measuring system comprises an elongate housing tube, which contains a metal strip, which is provided with a scale. The housing tube contains also a scanning unit, which is movable along the scanning tube to scan said scale. To ensure that the metal strip will be uniformly tensioned throughout its length and that the accuracy of the scanning operation will not be affected by a deviation of the longitudinal direction of the housing tube from a desired direction in which the measurement is to be taken or by changes of the length of the housing tube, the metal strip extends in the housing tube substantially without a longitudinal restraint and extends at both ends out of the housing tube and is held at said two ends by brackets, which are disconnected from the housing tube. In the housing tube, the side edges of the metal strip are entirely clear of the housing tube. The scanning unit is provided with guiding means, which are in sliding contact with both side edges of the metal strip and prevent a lateral wandering of the metal strip relative to the scanning unit.

Abstract: A variable pitch propeller has blades (36), the position of which, at relatively low pitch angles is controlled by a beta valve through a lever (23) and a feedback collar (25), the position of the collar being controlled by a plurality of beta feedback rods (55). There is one rod (55) for each blade of the propeller, and the movement of the rods (55) is controlled by a blade yoke (50) which has arms (52) partially encircling the rods (55). A lost motion connection in the form of a sleeve (60) is carried on each of the rods (55) and is movable against a retraction spring (62) by the arms (52). A movable stop mechanism (75) engages the feedback rods (55) at a particular low blade angle position and temporarily interrupts the movement of the feedback rods (55) while the sleeves (60) move to a seated position against the retraction spring (62), and thereafter the movement of the rods (55) is again picked up, accompanied by movement of the stop mechanism (75) against a spring (80). The lost motion connection represented by the sleeve (60) permits movement of the blades under control of the beta feedback valve without accompanying movement of the feedback rod which causes a shifting of the blades to a still lower pitch position, thereafter followed by reclosing of the feedback valve with continued movement of the rods (55).

Abstract: A method for cleaning gas/gas-heat exchangers contaminated with ammonium hydrogen sulphate, particularly Ljungström air preheaters of boiler plants equipped with DeNOx systems consists in that all the heating surfaces of the air preheater (2) are temporarily heated above the vaporisation temperature of ammonium hydrogen sulphate by passing through a gas stream and that the vaporised ammonium hydrogen sulphate is carried out with the gas stream, the heating surfaces being optionally heated with flue gas, hot air, heating gas, hot gas or with a combination of these types of heating. For example, a device for heating the heating surfaces with flue gas consists in that a bypass line (11) with a blocking flap (E) in front of the inlet-side blocking flap (A) comes from the fresh-air line (4) of the air preheater (2) and opens into the hot-air line (5) after the output-end blocking flap (B).

Abstract: An operable syringe assembly (20) includes a barrel (21) having a chamber (22) for retaining fluid. A proximal end (28) of the barrel includes an aperture (29) there­through. A distal end (25) of the barrel includes a passageway (27) therethrough communicating with the chamber. A stopper (35) is slidably positioned in fluid-tight engagement inside the barrel. A plunger rod (37), having an elongate body portion (38), engages the stopper (35) to facilitate operation of the stopper. The body portion (38) of the plunger rod extends outwardly from the proximal end of the barrel, through the aperture. A flexible cover (40) is attached to the barrel covering the aperture and containing that portion of the body portion of the plunger rod protruding from the aperture. The cover (40) is flexible enough and strong enough to allow movement of the plunger rod for operating the syringe without tearing. The cover acts as a barrier for helping to block the transfer of fluid and particulate matter between the chamber and the environment.

Abstract: A video camera with an optical system including a zoom lens system and a rear lens system provided therebetween wherein focusing is performed by varying the distance between the rear lens system and an imaging pickup device of the video camera. The video camera further includes a first sensor for sensing the position of the rear lens system to detect a relative distance between the rear lens system and the image pickup device, a second sensor for sensing the position of the zoom lens system to detect a focal length of the optical system. An arithmetic unit provided in the video camera calculates a distance to an object on the basis of the detected relative distance and the detected focal length and, in response to zooming operation, calculates a relative distance between the rear lens system and the image pickup device on the basis of the calculated distance to the object and the focal length detected by the second sensor. The arithmetic unit generates an error signal on the basis of the difference between the calculated relative distance and the relative distance detected by the first sensor and controls the position of the rear lens system on the basis of the generated error signal.
