Patent GB-2125987-A (GB)
Title: Improvements in or relating to the manufacture of zone plates
Inventor: HUTLEY MICHAEL CHRISTOPHER
IPC: G02B5/32
Filed: 1982-08-13
Abstract: The use of zone plates has been restricted by low efficiency and marked chromatic aberration. The increasing use of lasers reduces the disadvantage of chromatic aberration; and blazed zone plates have improved efficiency, but have been difficult to make. In the method of the invention, a Fabry Perot interferometer (28), capable of producing a concentric fringe image of high finesse, is made adjustable so that the image can be expanded (or contracted) over, typically, a range one fringe spacing. The image is projected onto a layer (12) of photo resist on a suitable substrate (10). While the image is expanded (say) through one fringe spacing, the light intensity in the image is varied, so that when the photo resist (12) is developed, the radial cross section between any two fringe positions takes on a wedge shape (18); which is that required in a blazed zone plate. Suitable chemical treatment can extend the wedge shape into the substrate partly or wholly. Efficiency of the order of 60% can be achieved.

Title: Method and apparatus for rethreading tubular members and resulting product
Inventor: HAYGOOD JERRY
IPC: B23G1/00
Filed: 1982-11-05
Abstract: A method and apparatus is disclosed for rethreading damaged or incorrectly threaded tubular members such as tool joints, casing, and tubing for oil wells, which methods and apparatus are particularly advantageous for use with NC and CNC machines. A standard numerical production program of the machining system is operated to form a standard acceptable thread and sealing surface for a tubular blank member (35). A threaded adapter (36) is placed on the newly formed threads. A preprogrammed position in the machining system advances a turret (12) toward the adapter (36) to a preprogrammed stopping point. A sliding locator assembly (25) is moved into aligning engagement with the adapter (36) and is locked in the turret (12) while engaged in the adapter. The program in the machine system is then operated to withdraw the turret (12) and locator assembly (25) from the adapter. The standard threaded blank (35) is removed from the collet (16) and a tubular piece (32) to be rethreaded is positioned loosely therein. The adapter (36) is threaded onto the tubular piece (32). The spindle (11) is rotated to align marks (42,43). The program system moves the turret (12) to the programmed stopping point. The tubular piece (32) and adaptor (36) are moved until the adapter engages the locator assembly (25) and the tubular piece 32 is then locked in the collet (16). The turret (12) moves to disengage the locator assembly (25, 111) from the adapter and the adapter is then removed. A rework program in the machine system forms a standard thread and seal surface on the tubular piece (32) a desired distance into the piece further than the production program which distance is some multiple of the width of one standard thread. <IMAGE>

Title: Process for producing nets of plastic material and apparatus for carrying out said process
Inventor: BERETTA MARIO
IPC: B29C48/10
Filed: 1984-06-11
Abstract: The strands making up the net, are extruded through a plurality of nozzles set along a pair of counter-rotating annular dies (2,3), to form a tubular net which is taken from the die along a stationary spindle (4) immersed in coolant (water), and cut along a helical path by a fixed cutter (5), to produce a strip 6. The strands of the tubular net have an inclination that can vary as a function of the speed of the counter-rotating dies (2,3), and this enables the strip to be at an inclination to the strands, thereby avoiding irregularities in a reel wound from the strip, and deposits from the cooling water and wear on the spindle, that would otherwise occur with net strands extruded from a fixed outer die (3). The invention relates also to the apparatus for carrying out said process, comprising an annular heater disposed around the outer die (3), at a slight clearance from the die. The rotation of the outer die (3) avoids temperature irregularities from the heater, and avoids temperature stagnation of the extrudate. <IMAGE>
