Patent GB-1285184-A (GB)
Title: Optical image-splitting systems
Inventor: SMITH FRANCIS HUGHES
IPC: G02B21/00
Filed: 1969-04-30
Abstract: 1285184 Image splitting devices VICKERS Ltd 29 April 1970 [30 April 1969] 22127/69 Heading G2J An image splitting device 3, preferably for measuring diameters of objects viewed under a microscope, comprises:- a group of plane reflectors 20, 22, 24, mounted so as to permit adjustment of the disposition of at least one of the reflectors relative to another, for receiving a primary light beam and emitting two secondary beams whose separation is variable with the above adjustment; first optical imaging means 25, 18 upstream of the group for forming an image carried by the primary beam; and second optical imaging means 6 downstream of the group for forming in one plane images 28, 29 carried by the secondary group. An image of the field of view 30 is focused by an objective 1 in a plane 26, the primary light beam from the field of view being deflected by the underside of metallized surface 13 of a prism 14 in the image splitting device 3. The beam is then focused by lenses 25, 18 and passes into a cube 20 having a semi-reflective surface forming a plane reflector, whereby a beam reflected from it is polarized so that its strongest vibration is perpendicular to its plane of incidence. The reflected beam from the cube is then reflected by a front surface mirror 22 forming another plane reflector and passes twice through a quarter-wave retardation plate 21, the polarisation of the beam being thereby altered so that after reflection it passes through the cube to form one of the secondary beams. Similarly the beam passing through the cube is reflected by another front surface mirror forming a further plane reflector 24 and passes twice through another quarter-wave retardation plate 23 whereby the beam is then reflected by the cube to form the other of the secondary beams (shown superimposed) which are then reflected from the underside of the metallized surface 13 in the prism 14, through the second optical imaging means, a lens 6, and into a binocular viewing head 4, where images of the field of view 28, 29 are formed in one plane. The beams may be separated by adjustment comprising rotation of the prism 20, or alternatively rotating the mirrors 22, 24 together, by for example a calibrated screw thread, whereby a diameter of an object is measured by viewing its two images, touching, side by side. A thick quartz plate 27 or alternatively a quarter-wave retardation plate is included to circularly polarise the secondary beams, since a beam-splitter 7 in the viewing head 4 is sensitive to plane polarisation caused by the cube 20. The plate may be removed for monocular viewing. A K-prism 16 may be included to rotate the image of the field of view carried by the primary beam, so that several diameters of an object in the field of view may be measured without touching the object itself.

Inventor: BAKER PETER ARTHUR
IPC: C08K13/02
Filed: 1958-07-18
Abstract: Synthetic linear polyamides are stabilized against the destructive effects of exposure to heat and oxygen by incorporating into the polyamide during or after manufacture, a hydrochloride, hydrobromide or hydroiodide of an organic base in the proportion of 0,005 to 3,0% by weight of the polyamide together with a copper compound soluble in the polyamide in the proportion of from 0,001 to 0,03% by weight of the polyamide and/or phosphorous or phosphoric acid in the proportion of from 0,1 to 1,0% by weight of the polyamide.  The organic bases are defined as those which can become chemically incorporated into the polyamide without detriment to its stability when the polyamide is exposed to the combined influence of heat and oxygen e.g. hexamethyleneimine, piperazine, morpholine, substituted morpholines, piperidine, substituted piperidines, pyrrolidine, substituted pyrrolidines and open chain aliphatic diamines.  The copper compounds soluble in the polyamide are defined as those copper compounds which are capable of being dissolved or uniformly dispersed in the polyamide e.g. copper acetate, the copper salts of adipic and sebacic acid and copper halides, phosphates and phosphites.  In Examples (1) and (2) hexamethyle diammonium adipate is condensed in the presence of (1) aqueous acetic acid, copper acetate and hexamethylene diamine dihydroiodide and (2) copper acetate, hexamethylene diamine dihydrobromide and sodium phosphite pentahydrate whilst in Example (3) nylon 6,6 delustred with TiO2 is dissolved in formic acid, copper acetate and morpholine hydroiodide added and the product cast into a film.
