Title: Photographic Elements with Improved Surface Characteristics
IPC: G03C1/95
Filed: 1981-05-22
Abstract: It is generally undesirable to have surfaces on photographic elements which are highly reflective and therefore reduce the attractiveness of the image. One of the traditional means of correcting this reflectance is to coat the developed film or print with an anti-reflective coating or to place a glass cover over the imaged photographic element where the glass itself has an anti-reflective surface. According to the present invention, an anti-reflective surface may be provided within the photographic element itself by including within a top coat gelatin layer: (1) a water- soluble dextran incompatible with gelatin; or (2) a combination of a first water-soluble soil matting agent incompatible with gelatin and a second water-insoluble soil matting agent.

Title: Metal strength testing
Inventor: RUSSELL ALAN AUBREY
IPC: G01N3/00
Filed: 1981-09-03
Abstract: A method of verifying the strength of the material of a hollow metal article, such as a nut or collar, which includes the steps of splitting the article longitudinally to form a slit extending through the wall from the inside to the outside of the article, widening the slit to flatten the article to a state wherein the cut faces originally defining the slit are moved to define opposite end surfaces of the flattened article; subsequently heat treating the flattened article with the heat treating of other articles made from the same material, and thereafter performing a strength test upon the test piece. The strength evaluation is more realistic than evaluations made from test pieces made directly from the original material, which latter may give an unduly high evaluation e.g. up to 70 to 80 DEG  greater than the actual strength of the material in the finished article.

Title: Oil system for aircraft gas turbine engine
IPC: F01D25/20
Filed: 1981-09-25
Abstract: A fully aerobic oil system for an aircraft gas turbine engine includes two re-circulatory oil systems the pumps for which have inlets 19 and 31a disposed at locations in the engine such that when one inlet is starved of oil, due to the aircraft attitude changing, oil will be supplied to the other one. A breather (30) of the type described in UK Patent No. 1,508,212 is positioned in the gearbox 22 and provides the lowest pressure point in the system. The bearing chambers are pressurised with air from the engine and the air/oil mixture in each chamber is vented via vents 27 to the breather where the air and oil are separated. The breather is used to pump the separated oil back to the oil tank 18 via line 35 and relief valve 38. In normal flight pump 20 supplies the bearing chambers via gallery 23 from the tank 18, relief valve 38 being open and check valve 37 being closed, and oil is returned via line 26. When the inlet 19 is starved of oil because of inverted flight, the pressure in gallery 23 drops to the extent that check valve 37 opens and the breather 30 then pumps oil from the gearbox via pipe 36 and gallery 23 to the bearings, which oil is returned to the breather via pipe 28. in an alternative embodiment, pump 20 is common to both re-circulatory oil systems. <IMAGE>
