Abstract: Abstract of the Disclosure A device has a cylindrical housing with a pointed front portion, which accommodates a striker separating the inner space of the housing to form a front and rear active chambers. The striker is provided with an open space at the rear end face thereof which mounts an air distributing branch connection treaded in the housing to be axially displaceable therein for reversing the device motion and adapted to admit compressed air to the active chambers and discharge it to the atmosphere therefrom thus reciprocating the striker which applies impacts to the housing.  The air distributing branch connection has pipes arranged coaxially and forming longitu-dinal passages, of which the central passage serves to admit compressed air to the active chambers, while the annular passage between the pipes is used to discharge spent air from the active chambers.

Abstract: A B S T R A C T   A manhole closure assembly prevents storm water from entering into manhole opening.  A separate support ring for the assembly has a lower closure supporting flange with an upper flange spaced therefrom, and sealing material is provided on lower flange.  The closure assembly includes a substantially circular cover plate engaging sealing material, and the cover plate comprises a pair of semi-circular segments.  Structure is provided for holding semi-circular segments of the cover plate together at diametral edge portions thereof.  Spaced apart biasing structure is located along arcuate edge portions of the cover plate, and such structure extends between plate and upper flange of support ring for urging plate against sealing material.  When pressure force acting upon underside of the cover plate exceeds force of biasing structure, arcuate edge portions of the cover plate lift away from sealing material to relieve such pressure force.

Abstract: Abstract of the Invention A welded wire mesh strip employed to reinforce a concrete pipe coating has its longitudinal wires deformed to an extent that increases progressiv?l? across the strip.  The coating is applied to the pipe by rotation of the pipe while moving it past a concrete spraying station and simultaneously winding the reinforcing strip onto the concrete to become embedded therein. The non-uniform deformation of the longitudinal wires enables the strip to accommodate to the frustoconical shape that the exposed concrete temporarily assumes at the spraying station.

Title: Pretreatment of portion of ferrous metal strip with phosphoric acid solution to prevent subsequent galvanization thereon
Inventor: HUNTER ROBERT F
IPC: C23C2/02

Granted: 1980-07-08
Abstract: ABSTRACT OF THE DISCLOSURE Mild steel strip is galvanized in selected areas only, typically on one side only of the strip, by pretreating the areas selected for absence of galvanizing to form thereon a readily chemically strippable coating of chemically-hydrated compounds non-wetting in molten zinc. Preferably, the pretreatment is carried out using phosphoric acid solution to form thereon a thin coating of a composite of hydrated iron phosphates and iron hydroxides. After passing the thus-treated steel strip through the molten zinc bath and solidification of the zinc coating, the composite coating is removed by dilute mineral acid.  Mild steel strip galvanized on one side using this procedure has particular utility in the automotive industry.
