Title: Tightening device for the wings of windows,doors and the like
Inventor: FRANK GMBH W
IPC: E05D15/48
Filed: 1972-10-18
Abstract: The opening in a window casing assembled from four lengths of extruded aluminium channel is provided with two sliding sashes having frames of extruded aluminum. The lower horizontal frame member of one sash rides on wheels whose rim matches the semicylindrical top face of a guide rail on the lower horizontal casing member so that the sash may be pivoted about the axis of curvature of the guide rail face. Tilting of the sash is limited by brackets, each bracket including a slide guided along the upper casing member and a link pivotally connecting the slide to the top of the sash. When the sash is locked in the plane of the casing, sealing strips on the sash cooperate with sealing surfaces on the casing above the pivot axis while the engaged sealing strip is kept straight by abutting engagement of respective abutment faces on the lower casing member and the sash below the pivot axis.

Title: Porous irrigation pipe and method
Inventor: MASON JAMES WILLARD
IPC: B29C48/10
Filed: 1984-02-24
Abstract: A mixture of virgin crumb rubber sized to between 30 mesh and 100 mesh containing less than 5%+100 fines and thermoplastic binder, such as carbon black filled polyethylene containing a coating promoter, such as a citrate salt and lubricant, such as a calcium stearate, is mixed in a vented Banburg mixer heated to at least 350 DEG  F. to remove volatiles through vent before extrusion. The mixture is formed into sheet in the nip of a two roll assembly and cooled in air before diced into pellets by a dicer. The pellets are formed into porous pipe by extrusion in a pipe extruder having the feeding, transition and metering zones separately heated to temperatures from 320 DEG  F. to 400 DEG  F. (T1, T2, T3). The die has a separate jacket receiving heat exchange fluid for heating the die to a temperature from 290 DEG F. to 380 DEG  F. to form a porous pipe having more uniformly spaced and sized pores and a smoother inner wall surface. The linearity factor, tensile strength and elongation are also improved.
