Abstract: Elements for making butt splices in optical fibers are simplified when formed of a deformable material and formed to define three surfaces (18,23,30) for contacting the fibers to be spliced. The surfaces are formed between two legs (20,21) of an element such that when the legs are closed onto the fibers the surfaces center the fibers and afford a resilient spring compression reserve force on the aligned fibers to maintain them in contact and the fibers are depressed into the surfaces slightly to center the fiber cores. Should one fiber be larger than another, the surfaces will deform sufficiently to clamp onto both fiber ends and be deformed even by the smallest of the two fibers. Thus, the splice element 11 will center the cores of the optical fibers such that in aligned position 90% or better of the surfaces of the core portions be aligned.

Abstract: DADMAC containing polymers, both homopolymers and copolymers are used in effective coagulating amounts to treat cellulosic fibres recycled from coated broke recovery. The DADMAC containing polymers are either homopolymers or are preferably copolymers containing acrylamide. Recycle of coated broke can cause difficulties when the fibres are recycled to the paper manufacturing process because the coatings contain binders which cause what is referred to as "white pitch", the accumulation of which can cause holes in the paper, build-up of residues and sticky masses, and clogging of felts and the like in the manufacture of paper. The use of the DADMAC polymers eliminates this difficulty in making paper from recycled cellulose fibres obtained from coated broke recycle.

Abstract: In accordance with the method of the present invention for manufacture of Swiss cheese from milk, the fat level of milk is standardized to about 3.5%. The milk is subjected to membrane processing by ultrafiltration and diafiltration to provide a retentate with particular characteristics. The retentate is then fermented with a particular blend of a coccus culture and a high level of a rod culture. The usual propionic acid-forming micro-organism, such as Propionibacterium shermanii, is used. The fermentation is desirably carried out at high temperatures to achieve the results of the invention. The fermented retentate is then evaporated to a solids level desired in the finished Swiss cheese, which is generally in the range of 35% to 41% moisture. The fermented and evaporated product is suitable for packing into containers to be cured and to provide Swiss cheese without further manipulation or treatment. The particular conditions are necessary to provide the desired Swiss cheese.

Abstract: This invention relates to an above knee prothesis which employs a hydraulic damper to passively regulate the angular velocity or rotation of the artificial knee joint. A programmed microprocessor recognizes common gait patterns from information received from strain and knee angle sensors on the prosthesis. The microprocessor reacts at various transition points in the gait by activating a motor which in turn adjusts a valve assembly in the damper. The valve assembly is capable of variably and separately damping the knee joint motion in each of flexion and extension at the same time. Gait is improved because of the improved extent of control of knee action. In addition, distinct routines such as stair descending and sitting down can also be practised. <IMAGE>
