Abstract: Process for electrostatically coating objects with a fluid, for instance liquid paint, by applying a high voltage to a spray bell and by feeding the fluid to a revolving, driven spray bell. The flow-rate of the fluid supplied to the center of the spray bell is decelerated nearly to zero when it enters the bell, then the rate of the fluid is increased by being accelerated by the bell to 15,000 to 60,000 rpm, and the fluid thereupon is centrifuged off the spray rim of the bell and is guided to the object to be coated.

Abstract: A method for producing "dogbone" filament fibers hav­
ing nodules at each end comprising rotating a heat extract­
ing disk having an edge tapering to a narrow peripheral sur­
face and having the peripheral surface notched at intervals 
with each notch comprising a leading edge, connected to a 
trailing flat surface, the trailing flat surface supporting an 
expanded land on the peripheral edge; introducing the rotat­
ing disk into the surface of a pool of molten material to form 
a film of the material on the edge; and removing heat from 
the film and at least partially solidfying the film on the edge. 
By the method, the segmented filament fiber products which 
are produced have a nodule formed on the leading end, a 
nodule formed on the trailing end, and continuous fiber in 
between, with the general appearance of a dogbone.
Patent EP-0078604-A3 (EP)
IPC: G02F1/1335
Filed: 1982-09-22
Abstract: A laser addressed reflective mode liquid crystal light 
valve includes an anti-reflective coating of only a single 
layer of cermet which is vacuum deposited in a partial 
pressure of oxygen to produce a combination of chrome 
and chromium oxide, the single layer anti-reflection coating 
both absorbing light at a wavelength corresponding to a 
laser beam wavelength and reflecting all other wavelengths 
with a higher reflectance. Some advantages are that fabrica­
tion is made easier by the elimination of multiple layers in 
the anti-reflection coating while laser beam absorption is 
enhanced by the single layer anti-reflection coating without 
causing a corresponding decrease in image resolution.

IPC: A61F13/15
Filed: 1985-05-28
Abstract: The invention relates to a pad that has as the outer 
impervious layer a polymer sheet integrally bonded to a 
fabric material such that the fabric material is on the exterior 
of the polymer sheet. The fabric is exposed on the body side 
of the pad when the edges of the pad are wrapped with the 
impervious liner to form baffles. The absorbent material 
forming the inner portion of the pad is integrally connected 
to a pervious body-side liner material. The connection of 
pervious liner to absorbent is such that when the pad is 
manipulated the pervious liner material stays in contact with 
the absorbent material and aids in transfer of liquid through 
the pervious liner into the absorbent. The fabric forming part 
of the impervious layer is preferably hydrophobic.

Abstract: A multiplex optical sensing system comprises an optical 
fibre 5 arranged to be subjected at the longesth length to 
fibre deforming forces during operation of the system and 
means 1, 2, 3 for producing a plurality of pulse trains of 
coherent light in which the frequency of frequencies of F1 + 
ΔF1, F2 + ΔF2, F3 + ΔF3 of the pulses in respective pulse 
trains lie within a different frequency channel for transmis­
sion along said optical fibre 5. The optical fibre 5 is provided 
along its length with a number of equally spaced discon­
tinuities 6 to 14 which effectively divide the fibre 5 into a 
plurality of discrete fibre elements so that a small proportion 
of each light being pulse being transmitted along the fibre 5 
will be reflected back along the fibre from each of the 
discontinuities 7 to 14 whereby, within any one of the pulse 
trains, each reflected light pulse after the first is superim­
posed upon either the previously reflected pulse from the 
preceding discontinuity or a reference light signal of the 
same frequency or a frequency with a constant difference 
frequency to the said transmitted light signal to produce an 
electrical signal in square law photo-detection means 15, the 
difference between respective electrical signals correspond­
ing to successive fibre elements being dependent upon the 
length of the fibre elements so that changes in optical path 
length of these elements produced by the incidence of 
deforming forces will result in changes in the electrical 
signals which will be detected.
