摘要:
A grounding block electrical connector is provided with a housing, electrical contact terminals, a housing insert, retainer clips, and a top cap. The housing is a one-piece metal member with a receiving cavity, top rivet posts, bottom rivet posts, and drainage holes. The contact terminals have contacts located in the receiving cavity and an integral busing strip. The busing strip is electrically and mechanically connected to the housing by the bottom rivet posts. The housing insert is located in the receiving cavity and has holes with the contacts located in the holes. The top cap is fixedly connected to the top of the housing over the receiving cavity by the top rivet posts. The housing insert has posts extending from its top surfaces that are located in post apertures of the top cap to thereby hold the insert at a stationary position in the receiving cavity.

Corrosion inhibiting compositions for addition to aqueous acid metal cleaning compositions for use in the cleaning of surfaces of metal parts which are contaminated with water insoluble, acid soluble deposits, wherein the corrosion inhibiting composition contains a partially hydrolyzed protein which is either a partially hydrolyzed gelatin, a partially hydrolyzed casein or a mixture thereof wherein the partially hydrolyzed protein has a total nitrogen content of from about 10 to about 20% by weight and a free amino group nitrogen content of from about 4 to about 30% based on the total nitrogen content. The invention also relates to aqueous acid solutions containing the corrosion inhibitor of the invention and to processes for treating contaminated metal parts with such acid compositions.

A method of forming identification markings on a thin walled can, includes the steps:(a) forming the can bottom wall to have outwardly concave shape,(b) providing a punch and forming discrete projections thereon to be separated from one another,(c) and displacing the punch relatively toward the can concave bottom wall to cause the projections to penetrate the wall to depths less than the wall thickness, thereby to form discrete and separate indentations in the can wall, the identations defining at least one recognizable alphanumeric character, and(d) relatively retracting the punch away from the can bottom wall.

An inline tool tracking system for tracking an inline tool traveling along a pipe includes a detection and communication device operable to detect an inline tool as it passes generally near the device. The detection and communication device is operable to generate a detection output, which includes data indicative of the detection of the tool and a geographical location of the device. A control is operable to wirelessly receive the detection output and to process the detection output. The control generates a control output responsive to the processing, and the control output is indicative of the detection of the tool and the geographical location of the detection and communication device. A display device receives an input indicative of the control output and displays the information indicative of the detection of the tool and the geographical location of the detection and communication device to a user of the display device.

摘要:
A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with the ink source, an ink outlet in fluid communication with the print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.
摘要:
An electrical terminal block includes a housing top, a housing bottom, and a plurality of electrical contact terminals. The housing top has a pattern of grooves extending into its bottom. The housing bottom has a pattern of tongues extending from its top. The housing top and bottom are ultrasonically welded to each other with the tongues located in at least some of the grooves. Different housing bottoms having different patterns of tongues can be selected to configure the terminal block to accommodate different types of electrical contact terminals having different numbers of contacts. The tongue and groove patterns can electrically isolate bases of contact terminals from each other.
摘要:
Apparatus for installing connectors to flat conductor cables comprising an installation station having a platen means for supporting cables in a generally horizontal plane and also having press means for coupling connectors to the cables supported thereat. The apparatus also includes magazines for supporting a plurality of connector portions in a generally vertical orientation and a transport station to sequentially move connector portions from the magazines to the installation station while reorienting them from a vertical orientation to a horizontal orientation. Also disclosed is the method for carrying out the installation with the above described apparatus.
摘要:
Apparatus for installing connectors onto flat conductor cables including an improved transport station for transporting connectors from a magazine to an installing station supporting a flat conductor cable. The transport means includes rotatable reorientation means to reorient connector portions at the magazines from vertical orientation to horizontal orientations at an intermediate location. The transport station also includes apparatus to retain connector portions on the reorientation means during transportation and also includes pushers to move the connector portions from the intermediate locations to the installation stations.
