Granted: 2007-09-25
Abstract: An assembly for isolating a mechanically sensitive electronic component, such as a computer hard drive, from shock and vibration, such as in a mobile vehicle application. The assembly is comprised of springs connected to the component, and a cage surrounding the component to limit its displacement. The springs suspend the component to minimize mechanical coupling from the vibration source to the component. Dampers are affixed to the component in order to dissipate mechanical energy as the dampers come into contact with the cage. The assembly is designed to isolate the component from operating mechanical shocks and vibration in the frequency range associated with a shock or vibration source.

Abstract: A unidirectional handle device for an endoluminal device includes an outer tubular member and an elongate inner member slidably received in the outer tubular member. The unidirectional handle includes a handle member, a needle bearing clutch disposed in the handle member, a control member guide, and shaft rotatable in a single direction disposed within the handle member. The shaft is rotatable in a single direction by its engagement with the needle bearing clutch. The shaft is in rotational engagement with the outer tubular member of the endoluminal device. The outer tubular member is slidable from a distal position to a proximal position when the shaft is rotated in the single direction. The unidirectional handle device provides substantially no backlash of the outer tubular member. In addition, the unidirectional handle device advantageously produces a tension-retaining effect during use.

Abstract: A description is given of a method as well as a plant for reducing the SOx emission from a plant for manufacturing cement clinker by which cement raw meal is preheated and burned in a plant comprising a cyclone preheater (1) and a kiln (7). The method is peculiar in that a catalyst in the form of a chloride compound and/or a mixture of several chloride compounds is introduced into the preheater (1) at its uppermost or next-to-uppermost cyclone stage (2, 3), that the catalyst is directed down through the preheater (1) to the kiln (7), that a partial amount of the kiln exhaust gas stream containing the catalyst in vaporized form is extracted from the kiln (7), that the extracted exhaust gas stream is cooled off so that the catalyst is present in solid form, that solid matter is separated from the cooled exhaust gas stream and that at least some of the separated solid matter containing the catalyst is recirculated for renewed introduction into the preheater (1).Hereby is obtained an effective reduction of the SO2 emission. The reason for this is that chloride compounds and/or a mixture of several chloride compounds will promote the reaction catalytically of SO2 with CaO for formation of CaSO3 and it will further promote the reaction of SO2 with CaCO3 for formation of CaSO3 and CO2. Since CaCO3 is present in great abundance, the SO2 reduction may be effected without any use of extraneous chemicals.

Abstract: A welded joint for metal pipes is provided with an inner lining, which is resistant to damage caused by the fluids flowing through them. The pipes are machined in the inside at the areas next to the ends to be joined, forming an undercut at each end. A spacer ring is inserted in the hollow annular space formed by both undercuts. The outer diameter of the spacer ring is substantially equal to the diameter of the corresponding undercuts, and its axial length is substantially equal or less than the sum of the axial lengths of the undercuts of the pipes to be joined. The spacer ring is made of an outer annular layer of a high thermal conductivity metal and at least one inner annular layer of heat-insulating and heat resistant material. The outer annular layer abuts in heat conducting contact with the metal pipes within said undercuts, and the metal pipes are joined by a weld seam.

Abstract: An automatic detecting and prewarning system for medicine installer mainly includes a clamp for easily clamping on a flow-indicating cylinder of the medicine installer, detecting means of an electronic sensor type mounted on the clamp, alarm means connected to the detecting means via a conductor, and a drop carrier pivotally connected to a lever to locate in the flow-indicating cylinder below a medicine dropper.      After a fixed number of drops or flow per minute is set for the medicine installer and input to the alarm means, medicine drops fallen from the medicine dropper one by one impact on and reciprocatingly sway the drop carrier to intermittently cut off the detecting means as a control signal to the alarm means. When an abnormal number of drops or flow per minute continues for a preset time, the alarm means is automatically enabled to emit warnings.

Abstract: An optical multiplexer and demultiplexer (mux-demux) (100) comprises a multimode waveguide (126) which communicates with first (122) and second (124) coupling waveguides. Multiplexed optical radiation comprising individual wavelength channels of appropriate wavelength introduced into the input waveguide is demultiplexed by means of modal dispersion and inter-modal interference within the multimode waveguide. The mux-demux consists of merely of waveguides and is therefore simple to fabricate and integrate with other components in integrated optical systems, and is capable of resolving channels having a small (.sim.1nm) wavelength spacing. The mux-demux may be used without modification as a demultiplexer and remains of simple construction when scaled up to operate with many channels.

Abstract: A gripping apparatus (100) for supporting a tubular includes a longitudinal opening extending therethrough. A bowl (25) is formed on an inner wall of the housing to provide an incline surface for one or more gripping members (20).  As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions (11, 12) coupled together using one or mores hinges (35). In one aspect, the bowl is formed as a recess in the inner wall (42) of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus.
