Title: Apparatus for shaping plastic foams
IPC: B29C48/90
Filed: 1979-12-17
Granted: 1983-05-11
Abstract: A foamable extrudate is extruded through the orifice (25), preferably arcuate, of an extrusion die (24). Immediately adjacent and downstream of the die orifice are opposed sets of curved rollers (47, 48), each having substantially the same center of curvature as the die orifice. The roller set (48) on one side of the extrudate pass line is adjustable as a set with respect to and substantially parallel to the pass line, while the rollers of the set (47) on the opposite side are adjustable individually cach to float with controlled pressure against the extrudate as it expands and moves between the roller sets. Each roller is comprised of a plurality of thin, cylindrical, circular wafers (195) which are drivingly interconnected and journaled on curved cure shafts (50). The wafers of opposed rollers in each set are individually driven for rotation at a controlled speed so that each opposed pair of rolls acts as a traction drive for the extrudate as it exits radially from the die orifice, such rollers controlling the expansion and movement of the extrudate while minimizing cell distortion. A surface finisher (45) is provided downstream of the roll sets which comprises opposed extrudate engaging planar surfaces (120, 121) positioned on the opposite sides of the extrudate, one (121) being adjustably yet fixedly supported while the other (120) is adjustably and floatingly supported pivotally at its center of gravity to exert a controlled flating pressure on the extrudate.

Abstract: Unsaturated acetoacetic acid esters are suitable as comonomers in the polymerization of unsaturated compounds in an aqueous medium. Particularly suitable are acetylacetoxyalkyl-allyl ethers which may be synthesized in an easy manner and correspond to the formulae <IMAGE>   or   <IMAGE>  Said allyl ether derivatives are especially prepared by reacting an allyl alcohol with an epoxide and reacting the resulting hydroxyalkyl-allyl ether with diketene. Both reaction steps are carried out at a temperature of from 0 DEG  to 100 DEG  C., preferably in the presence of a catalyst. The allyl ether derivatives may be copolymerized especially with vinyl compounds, such as vinyl esters, acrylic acid esters, olefins, vinyl halides and vinyl aromatic hydrocarbons.

Abstract: PCT No. PCT/FI82/00050 Sec. 371 Date Jun. 27, 1983 Sec. 102(e) Date Jun. 27, 1983 PCT Filed Oct. 27, 1982 PCT Pub. No. WO83/01679 PCT Pub. Date May 11, 1983.The invention concerns an automatic, mass-obturated hand firearm comprising a body (1) with handle (2), a barrel (3) joined to the body, a breech block (4) with guide (5) constituted by the body and with cocking and firing mechanism (7), the guide of the breech block ascending rearward so that the rearward path of motion of the breech block deviates upward from the center-line (8) of the barrel. The purpose is to eliminate the problem of automatic hand firearms that during shooting the barrel tends to rise upwards. As taught by the invention, when the breech block (4) is in its forward position its center of gravity (9) is located forward of the handle (2). The breech block (4) is preferably disposed to have its major part forward of the rear end (10) of the barrel (3). Furthermore, the center of gravity (9) of the breech block (4) is preferably located forward of the rear end (10) of the barrel (3). The guide (5) of the breech block (4) forms a preferably obliquely forward and downward inclined surface, against which the breech block rests so that when the rearward directed recoil force acts on the breech block this plug moves rearward and the surface of the breech block hits against the surface of the guide, producing on the body (1) a moment turning downward the muzzle of the barrel (3).

Abstract: A digital message transmission system has a transmit side wherein two pulse sequences are sampled at the rate of two plesiochronic data clocks and the sampled sequences are expanded by the insertion of additional information in the manner of "positive stuffing." The two pulse sequences including the additional information are transmitted to the receive side in a pulse frame, the procedure being reversed at the proceed side to decode the message. The momentary phase relationship between the two plesiochronic data clocks, in the form of a binary phase word, is inserted as a portion of the additional information. An auxiliary clock signal is derived from a reference data clock signal for use in transforming the phase measurement (difference between a higher and a lower frequency level) into the binary phase word. An auxiliary plesiochronic clock signal, which is plesiochronic relative to the auxiliary clock signal, is derived from the reference data clock signal and the plesiochronic data clock signal (plesiochronic relative to the data clock signal), the auxiliary plesiochronic clock signal being compared in phase to the auxiliary clock signal.

Abstract: In an activated sludge process for the purification of wastewater, in a completely mixed tank in the presence of carrier particles for the microorganisms, the aerating gas feed creates a tubular spiral circulating flow of the wastewater about a horizontal axis extending from the inlet zone to the outlet zone of the tank. To avoid a buildup of the carrier particles in the outlet zone of the tank, the gas feed maintaining the circulating motion is reduced along the axis of flow with respect to the gas feed set in the initial zone of the flow path. Gas may also be sparged along an axis transverse to the flow near the outlet to create a tubular flow which also clears the carrier particles from the outlet.
