摘要： An accumulator system for establishing a clamping force on dies in a closed die forging device. The accumulator system includes an accumulator having a differential piston and a free piston. The small end of the differential piston forms a wall of the accumulator oil chamber hydraulically connected to variable volume oil chambers behind the dies. The big end of the differential piston and one side of the free piston form a low pressure gas chamber of the accumulator. The other side of the free piston forms a wall of a high pressure gas chamber of the accumulator. As the dies of the forging apparatus close, oil in the chambers behind the dies moves the differential piston against only the gas pressure in the low pressure gas chamber so that closure is essentially without impact. Just before the onset of forging, the big end of the differential piston engages the free piston so that thereafter the two move as a unit against the higher gas pressure in the high pressure gas chamber of the accumulator whereby the clamping force on the dies increases at a higher rate.

摘要： Raw sewage may be presently treated by mixing screened raw sewage with activated carbon. The mixture is then allowed to stand in a first tank for a period required to settle the suspended matter to the bottom of the tank as a sludge. Thereafter, the remaining liquid is again mixed with activated carbon and the mixture is transferred to a secondary settling tank, where it is permitted to stand for a period required for the remaining floating material to settle as sludge and for adsorption of sewage carbon as well as other impurities to take place. The sludge from the bottom of both tanks is removed and pyrolyzed to form activated carbon and ash, which is mixed with the incoming raw sewage and also mixed with the liquid being transferred from the primary to the secondary settling tank. It has been found that the output obtained by the pyrolysis process contains an excess amount of ash. Removal of this excess amount of ash usually also results in removing an excess amount of carbon thereby requiring adding carbon to maintain the treatment process. By separately pyrolyzing the respective sludges from the first and second settling tanks, and returning the separately obtained pyrolyzed material to the respective first and second tanks from which they came, it has been found that the adverse effects of the excessive ash buildup is minimized, the carbon yield is increased, and the sludge from the secondary tank can be pyrolyzed into activated carbon to be used as indicated many more times than was done before exhaustion occurs.
摘要翻译： 目前可以通过将筛分的原污水与活性炭混合来处理生污水。 然后将混合物在第一个罐中放置一段时间，将其作为污泥将悬浮物质沉降到罐底。 此后，将剩余的液体再次与活性炭混合，将混合物转移到二级沉淀池中，在其中允许静置一段时间，剩余的浮动材料沉淀作为污泥和吸附污水，以及 其他杂质发生。 将两个罐底部的污泥除去并热解，形成活性炭和灰分，并与进入的原污水混合，并与从初级沉淀池转移到二级沉淀池的液体混合。 已经发现，通过热解过程获得的产量含有过量的灰分。 去除这种过量的灰分通常也导致去除过量的碳，从而需要加入碳以维持处理过程。 通过从第一沉淀池和第二沉淀池中分别裂解相应的污泥，并将单独获得的热解材料返回到它们来自的相应的第一和第二罐，已经发现过量灰分积累的不利影响被最小化， 碳产量增加，来自二次罐的污泥可以被热解成活性炭，比使用耗尽时多出多次。

摘要： An apertured part is pressed in a single cycle with no separate slug shearing operation. The press ram and bolster each contain fixed aperture forming punches which extend coaxially and slidably through piston like die supports, each of which is backed by a hydraulic fluid chamber. Separate systems control the fluid pressure in the two chambers so as to cause the dies supports to slide in one direction relative to the punches initially, then quickly in the other direction to shear the slug formed between the ends of the punches away from the part. The ram chamber is maintained at a high pressure throughout the first half of the stroke, while the bolster chamber begins at a low pressure and is allowed to rise to a higher, intermediate pressure that is still lower than the bolster chamber. Thus, the ram die support pushes the bolster die support down. However, when the pressure differential is removed, the two die supports quickly move up together over the fixed punches, shearing the slug out of the part.
摘要翻译： 在单个循环中按压有孔部分，没有单独的段塞剪切操作。 压力机柱塞和枕头均包含固定的孔口成形冲头，其同轴且可滑动地延伸穿过活塞式的模具支撑件，每个模具支架均由液压流体室支撑。 单独的系统控制两个腔室中的流体压力，以便使模具支撑件相对于冲头在一个方向上最初滑动，然后在另一个方向上快速地移动，以将形成在冲头端部之间的部分切断远离零件。 冲程室在行程的前半段保持在高压，而缓冲室在低压下开始，并允许升高到仍然低于摇枕室的较高的中间压力。 因此，柱塞模具支撑件向下推动垫片模具支架。 然而，当压差被去除时，两个模具支架在固定的冲头上快速地向上移动，从而将零件剪切出零件。

摘要： In a raw sewage treatment process of the type where settling tanks are used for the purpose of permitting the suspended matter in the raw sewage to be settled as well as to permit adsorption of the dissolved contaminants in the water of the sewage. The sludge, which settles down to the bottom of the settling tank is extracted, pyrolyzed and activated to form activated carbon and ash which is mixed with the sewage prior to its introduction into the settling tank, for the purposes mentioned. Because the sludge does not provide all of the activated carbon and ash required for adequate treatment of the raw sewage, it is necessary to add carbon to the process. In accordance with this invention, instead of expensive commercial carbon, coal is used to provide the carbon supplement.
摘要翻译： 在原污水处理过程中，使用沉淀池的目的是允许原污水中的悬浮物质沉降，并允许将污染物吸附在污水的水中。 为了达到上述目的，沉淀到沉淀池底部的污泥被提取，热解和活化，以形成活性炭和灰分，其在引入沉淀池之前与污水混合。 因为污泥不能提供充分处理原污水所需的全部活性炭和灰分，所以必须在工艺中添加碳。 根据本发明，代替昂贵的商业碳，煤用于提供碳补充。

摘要： A thin, uniform, firmly adherent coating of metal gasification catalyst is applied to a carbon-graphite fiber by first coating the fiber with a film-forming polymer containing functional moieties capable of reaction with the catalytic metal ions. Multivalent metal cations such as calcium cross-link the polymer such as a polyacrylic acid to insolubilize the film by forming catalytic metal macro-salt links between adjacent polymer chains. The coated fibers are used as reinforcement for resin composites and will gasify upon combustion without evolving conductive airborne fragments.

摘要： The improved hemodialysis system utilizes a second polymeric membrane having dialyzate in contact with one surface and a urea decomposition solution in contact with the other surface. The membrane selectively passes urea from the dialyzate into the decomposition solution, while preventing passage of positively charged metal ions from the dialyzate into the solution and ammonium ions from the solution into the dialyzate.

摘要： A system for discriminating between the fluorescent emission from dye molecules bound to biological particles and the background emission from free molecules of the dye in the solution suspending the particles, where the quantum efficiency of the bound dye molecules because of their bound state, differs from the quantum efficiency of the unbound dye so that the emission from the bound dye exhibits a longer statistical decay lifetime. The system involves irradiating the particles in the solution with a mode locked laser, and measuring fluorescent intensity in delayed synchronism with the mode locking frequency.

摘要： The impact resistance of flame retardant composites, especially thermoplastic molding compounds containing over 60% hydrated mineral filler such as Al(OH).sub.3 or Mg(OH).sub.2 is improved by coating the filler with 1 to 20% of an elastomer. The composite will fail by crazing or shearing rather than by brittle fracture. A well bonded elastomeric interphase results by utilizing acidic substituted resins such as ethyl-hexyl acrylate-acrylic acid copolymers which bond to and are cross-linked by the basic filler particles. Further improvement in impact resistance is provided by incorporating 1 to 10% of a resin fiber reinforcement such as polyvinyl alcohol fibers that decompose to yield at least 30% water when heated to decomposition temperature.
