Abstract: A cooling system for condensing the exhaust steam of steam turbine plants, particularly of power plants, comprises a mixing condenser (12) connected to the outflow of the steam turbine (10), a dry cooling tower (14) connected to the cooling water circuit (18,22) of the mixing condenser, and a wet cooling apparatus provided inside the cooling tower. The wet cooling apparatus (28, 30, 32, 34, 36) is located at least partly in a box (40) for conducting ambient cooling air into the cooling tower (14), the box (40) being arranged inside the cooling tower (14). The wet cooling apparatus may comprise a wet surface heat exchanger (26), or, alternatively, water spraying means (64, Fig. 4). The box further encompasses a dry surface heat exchanger (44) provided after the wet cooling apparatus (28, 30, 32, 34, 36) as regards the flow direction (42) of cooling air. The air withdrawn from the wet cooling apparatus becomes warmed up while traversing the dry surface heat exchanger (44) and, thus, does not diminish the draft of the cooling tower (14) when mixing with the air flowing in through the main heat exchangers (16) of the latter.

Abstract: Isotropic porous polymer beads having a high surface porosity and large pore diameters from about 0.002 to about 5 microns are produced from solutions of an acrylonitrile polymer or a copolymer by a thermally-induced phase separation process. The use of mixed solvent-non-solvent combinations as solvents for the polymers, produces high pore content, substantially spherical beads having a morphology ideally suited to the chromatography of large molecules, such as proteins, and for enzyme-binding.

Abstract: The method uses a support (1) incorporating a pipe clamp (2) at one end and an electrically heated swaging die at the other. The liner pipe, external diameter larger than the bore of the pipe to be lined, is made of plastics or other suitable material and drawn at ambient temperature through the swaging die and threaded through the pipe to be lined. The diameter of the liner pipe is reduced to and/or maintained at less than the inner diameter of the pipe to be lined by the tension applied by the drawing force.The drawing restrains the radial expansion of the outer surface of the liner pipe as it emerges from the swaging die.

Within the nozzle head is located a rotatable element defining a through-hole. The through-hole is shaped in such a way that the opening at one end is of relatively small cross-section and at the opposite end of a relatively large cross-section. The rotatable element is sealingly arranged in the nozzle head and has an external groove. The rotatable element can be positioned in at least a first rotational position to facilitate flow of spraying liquid from the conduit, to the nozzle inlet, and through the through-hole in the rotatable element, to the nozzle outlet for forming spray jets at the outlet. A second rotational position allows liquid to be flushed through the conduit by flow of the spraying liquid from the inlet, through the groove, and exiting the nozzle through a flush hole. A third rotational position allows the through-hole to be flushed by the flow of spraying liquid from the nozzle inlet through the through-hole in a second direction opposite to the first direction.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: The artificial ligament implant according to the invention is in the form of an elongate woven strip (1) of aerated structure, comprising a central part (2) and two ends (3). The ends (3) are intended to be fixed on a bone, particularly by grafting. This implant is characterised by the fact that it comprises a central part (2), reinforced over at least the intra-articular part (a), the said reinforced part being thicker than the ends, in order to improve the mechanical properties, while at the same time maintaining a porous structure capable of permitting tissue reintegration. The strip (1) can advantageously be provided with a central strengthening part (4) which is attached and which has an aerated structure and is made integral by means of an overcast seam (5).

The principle is that the force to be provided is proportional to the muscular force that the user may provide. The non-circular front chain wheel essentially pertains to the cycle industry but may also find applications in other fields, for example physical exercisers for body building or reeducation, and in general all apparatus utilizing cycling motion and a chain or belt transmission system between the front wheel or wheels of the crank gear and one or a plurality of pinions actuating the device to be driven.

Abstract: A low NOx burner combustion system which may be adjusted for optimum burn rates, temperature and oxygen levels. The burner incorporates a plurality of gas nozzles which individually inspirate a portion of the combustion air and a spin vane diffuser to rotate and mix the gases within the primary combustion zone. The diffuser is axially adjustable in order to vary the distance between the vane and the first combustion zone while the blades of the diffuser can be angularly adjusted to optimize the rotation and mix of the gases. Air for combustion is supplied through primary, secondary and tertiary passages to create distinct combustion zones for complete combustion. The flow rate of the combustion air is controlled through a damper in accordance with the burn characteristics. The angular and axial position of the diffuser and the damper control of combustion air can be automatically adjusted throughout the firing range of the burner in response to demand levels. In order to convert existing burners to the efficient low NOx burner of the present invention the primary air chamber may be retrofit into the main burner chamber. In a further embodiment, flue gas is recirculated and mixed directly with combustion fuel prior to combustion for reduced emission levels.

The marker incorporates an assembled unit which may be readily installed within the roadway including a base housing, a depressible piston which carries a detachable lens assembly, and a compressible biasing assembly to facilitate depression of the piston and return to its original position. The piston is retained within the housing by a cap cooperating with the base. The cap includes an opening which has a lobed or scalloped configuration adapted to cooperate with the scalloped configuration of the piston thereby preventing rotation of the piston within the housing. The lens assembly is removable from the piston to facilitate simple replacement of the reflective lenses without removal or disassembly of the marker. The compression assembly fills substantially the entire interior of the housing and includes closed-cell members to eliminate absorption of moisture and damage from freezing.
