Abstract: PCT No. PCT/US87/00287 Sec. 371 Date Aug. 17, 1988 Sec. 102(e) Date Aug. 17, 1988 PCT Filed Feb. 6, 1987 PCT Pub. No. WO87/04972 PCT Pub. Date Aug. 27, 1987.Disclosed is a method and apparatus for avoiding the clumping of dry fibers having diameters and lengths in certain ranges during blending of such fibers into a dry or wet particulate material. The process comprises distributing fibers in a vaporous medium, and transporting fluidized fibers to a mixing zone containing a dry or wet particulate material. Concurrently with stirring and blending of the particulate material with fluidized fibers, the fluidized fibers having been separated at least partially from a fluidized vapor are gradually introduced into the mixing zone. This process avoids the phenomena of "balling" that otherwise occurs with certain fibers.

Abstract: An injection moulding apparatus (10) includes similar co-injection modules (12) each provided with common supplies (238-242) and supplied with different polymer materials at intermediate pressure by common plasticisers (14-18). Each module has a co-injection nozzle assembly (70) in wich each nozzle (148-154) is supplied with polymer at injection pressure by an injector (208) which receives polymer through a non-return valve (220). The injector is mounted alongside the nozzle on a polymer transfer plate (138-146), and has the position of its piston (212) controlled by a hydraulic actuator (214) under the control of a dedicated micro-processor (164) in accordance with a stored injection control program. Each polymer is injected by an injector (208) directly into the associated nozzle (148-154) and is controlled solely by injector operation, and without the use of any control valve between the injector and the nozzle. The module micro-processors are controlled by a host processor which organizes the operations of the apparatus.

Title: Ammonia synthesis gas
Inventor: PINTO ALWYN
IPC: C10G11/20
Filed: 1988-09-15
Abstract: Ammonia synthesis gas is prepared by primary and secondary reforming followed by shift and carbon oxides removal. So that the process can use naphtha and methane, eg natural gas, as alternative feedstocks, at least the initial part of the primary reforming catalyst is alkalised. When using a methane feedstock, the primary reformer heating and outlet temperature are reduced compared to when using naphtha, and the amount of air fed to the secondary reformer is increased, so that, after shift, the hydrogen to nitrogen molar ratio of the gas stream is lower and is such that the gas contains an excess of nitrogen. This excess of nitrogen is subsequently removed, eg from the ammonia synthesis loop by a cryogenic hydrogen-recovery unit treating a loop purge stream and recovering hydrogen for recycle to the loop.

Abstract: In a VLSI process, a first layer, typically of silicon nitride over an oxide-coated surface of a silicon substrate, is anisotropically etched fo form a pattern of openings having side walls. Then a second masking layer, typically also of silicon nitride, is deposited over the first layer, filling the openings and thickening the first layer. The second layer is then anisotropically etched back to the first layer thickness, thereby reopening the original openings but with reduced dimensions because of spacer portions of the second layer left along the side walls of the opening. In a modified process, a buffer layer is deposited over the first layer before deposit of the second layer. The process can be used either for forming openings in a layer to be used for masking diffusion, ion implantation or local oxidation or for forming vias in a spacer layer to be filled with a contact metal.

Abstract: A mechanical seal for sealing a shaft (2) guided through a wall (4), having a sliding ring (11) which is held rotationally fixedly on the wall (4), is sealed with respect to the wall and rests with its sliding surface (13) on the sliding surface (14) of an opposing ring (15) which is held rotationally fixed on the shaft (2). The sliding ring (11) is displaceable in the axial direction, is sealed by a secondary seal (10) and is prestressed against the opposing ring (15) by springs (12) which determine the closing force on the sealing gap in pressure-free operation. The opposing ring (15) is held by means of a force fit between the annular clamping surfaces (17a, 19b) of a carrier sleeve (17) which is fixed to the shaft (2), and a supporting sleeve (19) which is rotationally fixed and can be displaced axially thereon. The supporting sleeve (19) is prestressed against the axially fixed clamping surface (17a) of the carrier sleeve (17) on the one hand by bracing springs (20) whose force is greater than that of the springs (12) of the sliding ring (11), and on the other hand by hydraulic forces which are proportional to the pressure to be sealed and whose magnitude can be determined by selection of the diameter of the auxiliary seals of the supporting sleeve (19). In consequence, the opposing ring is subjected essentially only to those axial clamping forces and the deformations resulting therefrom which are precisely necessary for the pressure which is to be sealed, the damaging influence of a differential thermal expansion of the opposing ring and its carrier arrangement also being avoided. <IMAGE>

Abstract: The invention relates to a tailboard hinge having a hinge part (10) provided on the tailboard and possessing a hinge pin (15). Furthermore, a bearing lug (24) for the detachable reception of the hinge pin (15) is present on the loading surface. The hinge pin (15) possesses, moreover, a detent nose (17), so that the parts together form an unhinging safeguard dependent on the pivoting angle. Since known tailboard hinges are relatively complicated and the unhinging safeguard often operates precisely at critical pivoting angles, the object of the invention is to improve this. For this purpose, a specific angular orientation of the detent nose is provided, so that the unhinging of the tailboard is possible only within a specific angular sector. <IMAGE>
