Abstract: "Support for cylindrical objects such as rolled coils"     ABSTRACT OF THE DISCLOSURE     Cylindrical objects such as rolled coils are frequently stored supported on rows of supporting members which rows have along their length a regularly repeating hill and valley profile.  With increasing coil size and weight the supporting members tend increasingly to become damaged and stacks of several layers of coils become less stable.  To ameliorate these problems the supporting members are made of a resiliently deformable material such as a low density polyethylene and are so shaped when not deformed that the hill and valley profile has a series of upwardly projecting ridges, sloping regions extending downwardly away from each side of each ridge, and substantially horizontal regions between the sloping regions.  Preferably each supporting member has one centrally disposed ridge, a sloping region on each side of the ridge, and half of a horizontal region at each end.

Title: Apparatus for monitoring ice formation
Inventor: KOVACS PAUL
IPC: G01N21/17
Filed: 1982-11-12
Granted: 1985-09-03
Abstract: ABSTRACT            An ice monitoring apparatus contains a first continuous light source and a second light emitting source, a photo-diode which responds to light from both sources and a transparent sheet which is arranged in the path of light between the first source of light and the photodiode and the surface of which forms a surface for measuring the formation of ice.  As long as the measuring surface is not iced and the sheet is optimally transparent, the photo-diode is driven by the luminous flux from the first light source in the region of saturation, and the luminous flux from the second light source has little effect upon the photoelectric current.  When ice forms upon the measuring surface, the luminous flux from the first light source is weakened and the photoelectric current in the photoelectric cell is increasingly modulated by the luminous flux from the second light source.  The modulated photoelectric current  is used as a quantitative signal of the build up of the layer of ice.  An electronic circuit monitors the gradual decrease in transparency, to differentiate between dust on the sheet and ice formation.

Abstract: HYALURONIC ACID FROM BACTERIAL CULTURE            Abstract Hyaluronic acid, a polysaccharide, is prepared in high yield from streptococcus bacteria by fermenting the bacteria  under  anaerobic  conditions  in  a  CO2-enriched growth medium,  separating the bacteria from the resulting broth and isolating the hyaluronic acid from the remaining constituents of the broth.  The bacteria may be grown free of endotoxins by filtering all ingredients through a 10K Millipore? filter prior to inoculation of the medium and subsequently    maintaining    pyrogen-free    conditions. Separation of the microorganisms from the polysaccharide is facilitated by killing the bacteria with trichloroacetic acid.     After  removal  of  the  bacterial  cells  and concentration of the higher molecular weight fermentation products, the hyaluronic acid is isolated and purified by precipitation, resuspension and reprecipitation.

Abstract: ABSTRACT OF THE DISCLOSURE           A telescoping landing gear shock strut set which can provide both the main landing gear and auxiliary landing gear function, and which is affixed to and extendible from an aircraft, is restrained in an unenergized, compressed condition.          A high pressure gas charge is then provided between the extendible element of the strut and the element affixed to the aircraft.  Early in the takeoff run, the charge gas in the forward strut is released so as to pump the nose and rotate the aircraft to a high angle of attack appropriate for takeoff.          Subsequent to this rotation, but before the conventional takeoff speed is reached, the charge gas in the main strut is released to impart a vertical velocity to the entire aircraft, thus jumping it into the air.  Both the forward strut and main struts incorporate a hydraulic flow bypass function, so that the landing shock absorption function does not comprise the aforesaid energy release.  The struts also incorporate valves to discharge enough residual gas immediately at the end of the jump stroke so that the landing energy absorption mode is not compromised.  Following the main gear jump, the continuining horizontal acceleration provided by the propulsion engines, and continuously weakening vertical acceleration comprising gravity diminished by the wing aerodynamic lift, which is increasing with speed, results in an initially upward aircraft trajectory which does not return to earth.  A takeoff run with the aforesaid jump action is considerably shorter than the takeoff run without the jump function.  Although the jump takeoff speed is less than the conventional takeoff speed, and there would be a lift shortage in a straight flight path,  the centrifugal acceleration produced by the bending downward of trajectory, which is initially inclined upward, compensates for this temporary lift shortage.
