Abstract: A process for the polymerization of ethylenically unsaturated monomers wherein a solid, monomer-soluble, free-radical forming compound is used as initiator. The initiator is charged to the polymerization system in the form of an aqueous dispersion comprising an emulsifier combination which consists of an ethoxylated nonionic emulsifier with an HLB-value above 15, which does not contain cyclic inner ether bonds, and a non-ethoxylated nonionic emulsifier with an HLB-value below 9. The emulsifier combination has a resulting HLB-value within the interval 11-17 and the combination is used in an amount of at least 1% by weight based on the initiator. Polymerizates produced according to the method have good electric insulation properties. A means suitable for the polymerization of ethylenically unsaturated monomers consists of an aqueous dispersion of a free-radical forming initiator, which dispersion comprises the mentioned emulsifier combination in an amount of at least 1 percent by weight, based on the initiator. The dispersion preferably also contains a protrective colloid such as polyvinyl alcohol. The dispersions have good stability and are easy to handle.

Abstract: A method of forming a beam blank, wherein: said method comprises: a process in which a plate-shaped slab is reduction-rolled in the widthwise direction by means of working rolls having box calibers each formed at the center thereof with a belly, whereby side spreadings are generated at opposite end portions in the widthwise direction of said slab to provide a blank of being a dog-bone shape in cross-section; and a process in which said blank is rolled by means of working rolls having beam blank calibers to provide a beam blank being of a predetermined shape in cross section; said process, in which the plate-shaped slab is reduction-rolled in the widthwise direction by means of the working rolls having the box calibers each formed at the center thereof with the belly, preferably comprising: a first step in which said plate-shaped slab is reduction-rolled in the widthwise direction by means of box calibers each formed at the center thereof with a belly to provide grooves for positioning in the centers at opposite end faces in the widthwise direction of the plate-shaped slab; a second step in which said plate-shaped slab is further successively reduction-rolled in the widthwise direction by means of respective box calibers successively larger in caliber width than those used in the preceding step and each formed at the center thereof with a belly fit in said groove; and a third step in which said plate-shaped slab is further reduction-rolled in the widthwise direction by means of working rolls with flat bottoms or working rolls having box calibers each formed with a belly low in height, whereby recesses formed by use of said bellies at opposite end faces in the widthwise direction of the slab are lessened in depth and the side spreadings are further facilitated.

Abstract: A method of growing cells of the type which normally undergo mitosis only when anchored on a substrate, e.g., fibroblasts or epithelial cells comprises the steps of encapsulating a seed culture of the cells within a semipermeable membrane and suspending the capsules in a growth medium. The interior surfaces of the capsule membrane and/or collagen also enclosed within the capsules with the seed culture serve as a substrate for the cells. The ratio of the available substrate surface area to the volume of the culture may be so large that the cells grow substantially throughout the volume of the culture medium.

Abstract: In a manhole/access cover and frame assembly the cover is supported on the frame by pairs of downwardly facing, oppositely inclined support surfaces on the cover which are engageable respectively with corresponding upwardly facing, oppositely inclined support faces on the frame, and the cover has a substantially continuous downwardly facing ridged peripheral sealing surface which, when the cover is supported on the frame, overlies a substantially continuous upwardly facing ridged peripheral sealing surface on the frame. The engagement between the aforesaid support surfaces so locates the cover with respect to the frame that ridges on the sealing surfaces are interleaved but are held out of supporting contact with one another along substantially the whole of their length, so that the tortuous path between the ridges may be packed with grease to provide a gas and water tight seal.

Abstract: The combustion gas passages leading to a fluidized bed in a hot water or steam boiler are kept free of deposits which might block them by pulses of gas. The gas pulses may be generated from a pressurized reservoir with periodic or aperiodic openings of a valve in a gas line leading from the reservoir to the passages. Where the bottom of a fluidized bed comprises a pair of plates defining a plenum space therebetween and the combustion gas passages define nozzles extending through the plenum space, combustion air may be fed to the nozzles via the plenum space and the cleaning pulses may also be generated from gas supplied to the plenum space.

Abstract: A maneuver force gradient system causes a helicopter, that otherwise tends to pitch up in a banked turn, to pitch nose-down. A command signal (25) is provided as a function of the roll angle to operate the longitudinal trim actuator (27) which automatically moves the cyclic control (50) resiliently (28) forward to push the nose down. The pilot must consequently pull back on the cyclic control (50) to achieve a desired pitch attitude, thereby establishing a longitudinal positive maneuver-force gradient. The system is operable only when the pilot initiates a roll (33, 38, 50, 51) and the roll angle equals or exceeds 30 DEG  (30, 33, 36, 37). Both analog (FIG. 1) and digital (FIG. 2) embodiments are disclosed, and the invention may be practiced in association with an AFCS (101) having the longitudinal trim actuator (27) and resilient linkage (28).

Abstract: An indexable cutting insert comprises an upper surface, a bottom surface and side surfaces extending therebetween. Between two cutting corners, the rake surface is formed such that the rake angle is largest next to the two cutting corners and smallest at a point somewhere between the two cutting corners, preferably at or near the middle of the cutting edge. In this way, the cutting edge is strongest where the pressure load from the workpiece is largest, at the same time as a relatively small average rake angle is attained. This configuration decreases the cutting forces and the energy consumption.
