Abstract: ABSTRACT OF THE DISCLOSURE           An AC signal source having constant frequency-amplitude product is also easily realizable in hybrid microcircuit form.  A square wave oscillator output is rectified and clamped to a feedback control voltage.  The resulting controlled amplitude square wave is low-pass filtered to produce a sinusoidal output signal which is typically amplified and applied to a variable-impedance load.  The sinusoidal signal is also applied to a similar but simulated load of fixed impedance value and the current flowing through the simulated load is summed with a temperature-compensated reference current producing an error current which is then integrated to produce the feedback control voltaqe which controls the amplitude of the sinusoidal signal so as to maintain a constant frequency amplitude product.

Abstract: Abstract:          A connector comprises an insulating substrate having a plurality of through-holes and a first circuit pattern formed on the substrate.  Female contactors are located and fixed around the edges of such through-holes to form openings having edges that extend inwardly of the holes.          These female contactors are electrically connected to said first pattern.  A male contactor comprises an insulating substrate having a second circuit pattern thereon and a plurality of male contactor pins fixed to the substrate and electrically connected to the second pattern.  These pins are located in positions corresponding to the openings of the female contactors.  The female contactors are made of a thin film of a shape memory alloy and the edge of each female contactor is given, before inserting each of the pins, such a shape memory that the contactor is returned to a position to close the opening when the contactor is subjected to a temperature above the martensitic transition temperature.  The arrangment facilitates the miniaturization of connectors.

Abstract: Abstract The present invention concerns a holder which is intended for storing loose objects,  such as skis or other sports articles, or tools.  The holder comprises a body part and a number of fixing members consisting of elastic,  plate-like bodies bent to arcuate shape,  and fixed by the aid of engaging members on their ends  in a  slot  or  equivalent in  the body  part.   The fixing members are hereby  located side  by  side  and  leaning with their sides  against each  other,   and  the object to be stored may be fixed in the holder by pushing it in between two mutually  adjacent  fixing  members. It  is  essential  in  the invention that inside each fixing member bent to arcuate shape has been disposed a separate bracing member consisting of an elastic body bent to arcuate shape and the sides of which lean against the inner sides of the fixing member.  The purpose of the bracing member is to enhance the pressing force acting on the object fixed in the holder,  whereby the holder is suited better  than before for  storing objects  of relatively  large size.  The bracing member consists preferably of a plate-like body similar to,  but shorter than,   the fixing member and by the aid of engaging members at its ends attached in the slot in the body part of the holder in similar manner as the fixing member.

Abstract: ABSTRACT      A nondestructive examination method and apparatus for high resolution detection of cracks, defects or anomalies in radioactivity contaminated materials. The method relies upon radioactivity being carried by the normal reactor environment, or by an added radioactive penetrant fluid, to the cracks, defects or anomalies.  Detection of this radioactivity by a narrow well defined beam gives an improved measurement of the location and size of the cracks, defects or anomalies.  The apparatus includes a sensor mounted on a remotely controlled framework.  The sensor includes shielding to direct a very narrow beam of gamma radiation to a scintillation crystal and photomultiplier tube which converts the radiation into electrical signals.  The signals are counted by count rate means and converted to digital form and stored. Survey procedures are provided both for detecting cracks and for characterizing cracks once discovered. Computer aided imaging techniques are provided to construct graphical representations from the recorded data.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a Weak Pre-Deoxida-tion Process (abbreviated as W.P.D. process) for producing Al-killed and/or Ti-Killed steel.  In this process the proper amount of Si-containing ferro-alloy is added into molten steel during tapping, as Weak Pre-Deoxidation, then the ladle is transferred to Al-Wire feeder system or ladle injection treat-ing equipment to proceed final stage of deoxidation.  Not only can the recovery rate of deoxidizer be increased by this new process, but also the cleanliness as well as surface and inter-nal quality of products are effectively improved.  Besides, the production cost will be reduced due to less deoxidizer addition, less billet conditioning cost, less rejection and less customer claim.  Thus the W.P.D.  process  is a break-through in present steelmaking practice.

Abstract: ABSTRACT         A high strength mortar has been developed for use with silica brick, in the constructon of coke-oven heating walls.  When fired to conventional coke oven temperatures of about 1100°C, the mortar  develops a tensile strength within the mortar itself, and a tensile bond to the silica brick, which exceeds the tensile strength of the silica brick.  The mortar is composed of three primary solid constituents:  25 to 88 percent SiO2, 6 to 65 percent A12O3 and 4 to 12 percent P2O5.  To achieve such high tensile strength, the other solid constituents must be maintained at a minimum, desireably less than four percent and preferably less than two percent.

Abstract: ABSTRACT OF THE DISCLOSURE           A  method  and  apparatus  for  the  direct  heat treatment of a medium- to high-carbon steel rod in which the  formation  of  martensite  is prevented,  even  if  the starting billet contains segregation.  A hot-rolled rod is transported on a conveyor  in the form of a sequence of non-concentric  rings.    The  rod  is  then  subjected to controlled cooling in a coolant so that the greater part of  any  austenite in  the  entire  length  of  the  rod  is substantially  uniformly  transformed  to  a  fine  pearlite structure.   The sequence of non-concentric rings of the rod is next held at a temperature of 450 - 630°C for  a period of 60 - 300 seconds, with the pitch between each ring being made smaller than at the inlet of the conveyor.          Accordingly, a pearlite transformation is effected of any residual austenite.

Abstract: ABSTRACT OF THE DISCLOSURE         An intermittent drive mechanism is disclosed which includes a continuously rotating driving gear; a subordinately driven gear disposed proximal to the driving gear; an epicyclic gear capable of engagement with the driving gear by its own rotation along the periphery of the driven gear which remains engaged with the epicyclic gear; and a shift plate capable of causing the epicyclic gear to be either engaged with the driving gear or disengaged from it by its movement.  When the epicyclic gear is engaged with the driving gear, the rotational force of the driving gear is transmitted to the subordinately driven gear via the epicyclic gear, whereas the transmission of the rotational force is discontinued when the epicyclic gear is disengaged from the driving gear.  As a result, in response to movement of the shift plate, the subordinately driven gear is inter-mittently driven.

Title: Restoring framing in a communications system

IPC: H04N7/56
Filed: 1986-05-20
Granted: 1990-03-06
Abstract: ABSTRACT OF THE DISCLOSURE       A secure communications system requires special arrangements for the establishment and maintenance of framing and synchronization. A framing word is transmitted at A fixed frequency, and a key neces-sary to unscramble the transmission is transmitted in a fixed position in relation to the framing word. Synchronization information (reference clock bursts) is scrambled with the intelligence and may only be recovered once the key is available. When framing is being maintained, the receiver's phase-locked loop opens only during the short reference clock bursts in the incoming signal, and the framing signal generator is able to predict the occurrence of successive framing signals without reference to the incoming signal. When framing is lost, the receiver enters a "soft lock" condition in which its phase-locked loop is opened to receive the entire incoming signal and in which the framing signal generator refers solely to the incoming signal to generate framing signals.

Abstract: A method of operating an air-supplied type coating booth adapted to enforce conditioned air by an air supply blower through a filter downwardly to the inside of a tunnel-shaped coating booth at a predetermined flow velocity and then drawn to discharge together with coating mists, etc to the beneath of the floor comprises the step of detecting the flow velocity of conditioned air flowing through the filter to the inside of continuously, applying primary and secondary averaging processings for the detected signals containing variations fluctuating at relatively shorter and longer periods respectively, comparing the value obtained from the signals applied with the secondary averaging processing with a predetermined flow velocity value and variably controlling the flow rate of the air supplied from the air supply blower depending on the deviation and thereby maintaining the flow velocity of the conditioned air flowing to the inside of the coating booth always constant. Reduction of the flow velocity supplied to the inside of the air-supplied type coating booth due to the filter clogging can be compensated exactly with no effects of external disturbances.
