  • Publication number: 20040139927
    Abstract: A feline teething and teeth cleaning toy in which the combination of elements functions as a natural complete dental care device in a manner consistent with that of a toothbrush and dental floss while assisting the natural digestive process of cats. The combination of elements, a bone ring wound with natural hemp, natural feather(s) and natural dried catnip leaves utilizes a cat's natural instincts to promote its overall effectiveness. As cats instinctively enjoy playing with the toy, the chewing of the ring and hemp gently brushes and scraps the teeth and stimulates the gums. The chewing and pulling of the extended feather(s) and hemp through the teeth flosses the teeth and the consumption of the natural dried catnip leaves assists the cat's natural digestive process.

    Abstract: A shim attaching and detaching surface has a sectional portion with a smaller diameter than a base circle of a cam surface in a state in which the shim attaching and detaching surface of a cam is located on a tappet roller, and therefore the tappet roller and an arm member can be moved upward. Since an inner side of a top surface of a tappet guide is inclined, if the arm member is tilted along this inclination, one end of the arm member can be raised, and a clearance is formed in a space from a tappet shim. Accordingly, by inserting a slim plate-shaped or rod-shaped jig 128 from the clearance, the tappet shim 37EX can be attached and detached.

    Abstract: An apparatus for damping rotational vibrations in a power train comprises a free-wheel clutch between a driving element and a driven element. At the outer ring and at the inner ring of the free-wheel clutch there are formed clamping ramps cooperating with clamping balls lying therebetween. The clamping ramps are provided at the axial front sides of the rings of the free-wheel. One of the rings of the free-wheel clutch is arranged axially undisplaceable and the other ring is arranged axially displaceable. Between the axially displaceable ring and an axial buttress there is provided a spring element acting in axial direction. Thereby the transmission of rotational vibrations onto the driving element can be prevented due to an axial displacement of the constructional parts arranged therebetween up to their clamping, particularly with an increasing number of revolutions of the driving element.

  • Publication number: 20040139945
    Abstract: A common rail has an accumulation pipe in which high pressure fuel is accumulated, a pipe joint to which a high pressure pipe is connected and an orifice member housed inside the pipe joint. The orifice member is provided with a conduit through which a fuel port formed in the accumulation pipe communicates with the high pressure pipe. The conduit is provided at an end thereof with an orifice. The orifice serves to reduce pressure pulsation generated by fuel injection of an injector so that fuel pressure in the common rail is stable. Since the orifice is formed in the orifice member housed in the pipe joint, the orifice is easily and accurately manufactured at a lower cost, compared to an orifice formed in the accumulation pipe. It is easy to standardize the manufacture of plural models of common rails whose orifice diameters are different.

    Abstract: An emission control device for use with stationary or mobile gas-fueled internal combustion engines is described, which is placed in the fuel supply line and operates with full fuel authority. An oxygen sensor measures exhaust oxygen content. The valve internally houses a programmable microprocessor, a pressure transducer and a fuel flow conduit throttled by a balanced poppet valve. Signals to the microprocessor from the oxygen sensor, the pressure transducer indicating outflow gas pressure cause the microprocessor to motivate an actuator to move the valve within the gas stream and thus regulate the outlet pressure and also the gas flow rate to maintain a desired air/fuel ratio to the engine and keep exhaust emissions at an optimum level consistent with the engine operating load requirements and characteristics. Finite incremental control of valve position, preferably assisted by an internal position transducer, permits close control of the exhaust emissions.

The central receiver has a plurality of interconnected reflectors coupled to a tower structure at a predetermined height above ground for reflecting solar radiation. A plurality of concentrators are disposed between the reflectors and the ground such that the concentrators receive reflective solar radiation from the reflectors. The central receiver system further includes a heat removal system for removing heat from the reflectors and an area immediately adjacent the concentrators. Each reflector includes a mirror, a facet, and an adhesive compound. The adhesive compound is disposed between the mirror and the facet such that the mirror is fixed to the facet under a compressive stress.

  • Publication number: 20040139964
    Abstract: An actuation inhibitor for metered dose inhalers comprises an annular band of semi-rigid plastics material having a substantially circular cross-section, with an upstanding wall encompassing from about 260° to 315°, a gap in the wall of from about 45° to 100°, and a pair of outwardly projecting walls, one at each side of the gap. The inside diameter when at rest in an unstressed manner is slightly smaller than that of a medication canister. The height is from about 40% to 65% of the predetermined diameter, and the length of each of the projecting walls is from about 10% to 50% of the height. The semi-rigid plastics material is sufficiently flexible to permit the pair of projecting walls to be spaced apart one from the other by up to about a further 90°, and the plastic memory permits the spreading apart of the projecting walls without being overcome.

    Abstract: Inflator regulator having a threaded sleeve and a plurality of different size adapters for connection to a plurality of different size BC hoses. Connecting the inflator regulator to a selected BC hose is accommodated by selecting the corresponding size adapter. The selected adapter is inserted concentrically through the threaded sleeve and then mechanically affixed, such as by a plastic cable tie, to the end of the BC hose. The sleeve is then threaded onto the inflator regulator. In the event that it is desired to connect to a different size BC hose, the above process is simply reversed and repeated using an appropriately selected different adapter.

  • Publication number: 20040139971
    Abstract: The disclosed laryngeal mask airway device includes an inflatable cuff and an airway tube. The inflatable cuff defines a central opening at least when inflated. The cuff is insertable through a mouth of a patient to an inserted location within the patient. The cuff surrounds a glottic opening of the patient when the cuff is inflated and at the inserted location. The airway tube extends from a proximal end to a distal end. The airway tube defines an internal passage, an anterior portion, a posterior portion, a left portion, and a right portion. An airway passage extends from the proximal end of the tube through the internal passage to the glottic opening when the cuff is inflated and at the inserted location. The anterior portion is characterized by a thinner wall thickness than the left and right portions. The posterior portion is characterized by a thinner wall thickness than the left and right portions.

  • Publication number: 20040139972
    Abstract: A fixed length, immalleable stylet for insertion into an endotracheal tube with an articulating tip. The stylet is preferably curved, semi-rigid and shape-retaining. This stylet is of fixed length and when inserted into an endotracheal tube with an articulating tip, promotes rigidity of the main body of the endotracheal tube, while allowing full function of the articulating tip mechanism. The stylet cannot protrude beyond the flexion point of an articulating tip endotracheal tube. This combination allows the tube to be passed in even very difficult airways while preserving the articulation capability afforded by the endotracheal tube.
