  • Patent number: 5701750
    Abstract: A thermal zone demand controlled dual cascade arranged heat pump system and system controller for building spaces, having first and second heat pumps and having an air circulation system for circulating air to and from said thermal zones and including a conditioned air chamber having first and second heat exchange refrigerant coils being connected in refrigerant circulating relation respectively with the heat pumps. A plurality of thermal zone blowers conduct conditioned air, heated or cooled, from the conditioned air chamber to respective thermal zones of the building space. Electronic controller circuitry of the system is coupled for thermal demand control of the heat pumps and the thermal zone blowers for operation of the first heat pump to accommodate a predetermined range of thermal load and for operation of the second heat pump along with the first heat pump to accommodate a greater thermal load.

  • Patent number: 5697602
    Abstract: A container (10) for a filter (12) has a cylindrical housing (16) receiving the filter (12) and permitting replacement of the filter (12) from an open end. An enlarged diameter fitting (22) is secured about the open end of the cylindrical housing (16) and has retaining lugs (30) for retaining a removable end cap assembly. The removable end cap assembly has an anchor plate (40) with projections (46) that are received within arcuate slots (32) of the end fitting (22). The anchor plate (40) is coupled to an end cap (42) for rotation to position the projections (46) beneath the lugs (30) to restrain outward movement of the anchor plate (40). A single bolt (44) through the end cap (42) is threaded to the anchor plate (40). Rotation of the bolt draws the anchor plate (40) tightly against the lugs (30). The end cap (42) is simultaneously forced against an O-ring (36) disposed on the outer end (50) of fitting (22) for sealing the end cap to the container. An embodiment of FIG.

  • Patent number: 5678829
    Abstract: The present invention is a hydrodynamically lubricated interference type rotary shaft seal suitable for environmental exclusion and high pressure lubricant retention which incorporates an environment-side groove to control and minimize interfacial contact pressure at the dynamic sealing interface, which permits optimum hydrodynamic film thickness, thereby significantly lowering the self-generated heat produced by the seal, as compared to the prior art. The cool-running nature of the present invention permits the use of higher modulus seal materials and higher surface speeds, compared to the prior art, and allows the seal to operate in applications with relatively poor heat dissipation. The controlled interfacial contact pressure of the present invention also permits effective hydrodynamic lubrication with lower viscosity lubricants, including water.

  • Patent number: 5678615
    Abstract: A filler system to add water to a specified level in a cell of a storage battery mounted in a relatively inaccessible location includes a container for fill water connected by an elongated, flexible supply line and an elongated flexible air vent line to a hand-held fill valve assembly. The fill valve assembly includes a normally closed, manually opening water valve connected to the supply line and a normally open buoyant air vent valve that closes to prevent the flow of air to the interior of the container when the liquid level in the cell rises to its proper level.

  • Patent number: 5678293
    Abstract: A spreader tool (10) and method for spreading apart a pair of opposed parts (F) comprising a housing (12) having a central bore (18) with a piston (42) mounted therein for reciprocal movement. The lower end of the piston (42) has a center spreader member (45) secured thereto and fitting between a pair of side spreader members (30, 32). Upon actuation of the cylinder (42) the center spreader member (45) moves in a parallel relation to the adjacent side spreader members (30, 32) for spreading the members (F) apart. The tool (12, 12A) may be manually actuated by a ratchet handle (66) as shown in the embodiment of FIGS. 1-3, or may be hydraulically actuated by pressurized hydraulic fluid from a pump (P) as shown in the embodiment of FIGS. 4-6.

  • Patent number: 5678503
    Abstract: A method of mooring a storage vessel in the sea is provided. A turret is mounted in a well forward of the vertical center-line of the vessel. A plurality of anchor legs are disposed between the sea bed and the turret. Each anchor leg is fixedly secured to the turret. A mooring buoy is fixedly secured at a submerged position in each anchor leg. The position and buoyancy of the buoy is selected so that normal anchor leg catenary forces which are largely vertical at the connection to a turret have enhanced horizontal components due to the buoyancy of the buoy holding up the anchor leg at a submerged position in the sea. Such enhanced horizontal components enable sufficient torque to be developed between the vessel and the turret so that the vessel may weathervane due to environmental forces such as wind and current. Accordingly, the vessel may be maintained on station and achieve a heading toward environmental forces without the need for auxiliary thrusters or separate turret drives.

  • Patent number: 5676161
    Abstract: A mastopexy or mammaplasty procedure to reshape and/or reduce the size of sagging breasts includes the steps of making a generally anchor-shaped incision having a bottom line along the inframammary crease, using a circular cutter to form the top portion of the incision and an incision around the areola to reduce the diameter thereof, after removing excess skin inside the incision, and breast tissue in the case of mammaplasty, shifting the areola, nipple and underlying breast tissue upward to position the areola/nipple complex within the circular top portion, pulling the flaps of skin formed to the sides of the incision down and around the areola and underneath same, and then suturing adjacent skin edges to complete the lifting and reshaping.

  • Patent number: 5675551
    Abstract: Apparatus and method are disclosed for use with a horizon picking method for 3D seismic data. Variables such as picking method, whether simple or iterative, score required of an iterative method and .DELTA.T between target wavelets and seed wavelet are input into the computer. During the picking process, parameters as to the number of successful picks and the number of failed picks because of the method of picking and because of failed picks due to the score not being achieved in the iterative method and because of failed picks due to the difference in time between the target wavelet and the seed wavelet being greater than the .DELTA.T variable are recorded. The number of score failures to pick a target wavelet from a seed wavelet is recorded where the score achieved is less than the input score. A characteristic of such number of score failures, such as the percentage of score failures to the total number of picking tries, is displayed on a CRT screen.

  • Patent number: 5664577
    Abstract: Apparatus and method for the recording of distortion product emission (DPE) levels in human beings. At least one microphone and a sound-delivery system is inserted in the external ear canal. Two primary tones T.sub.f1, T.sub.f2 are applied simultaneously to the ear. The cochlea of the inner ear produces a DPE tone which is sensed by the microphone. DPE levels are sensed as a function of input frequencies f.sub.1 and f.sub.2. Such DPE frequency is equal to 2f.sub.1 -f.sub.2. Such DPE frequencies are collected in 100 Hz step by adjusting f.sub.1 and f.sub.2 and maintaining a substantially constant ratio between f.sub.1 and f.sub.2. Two output forms are created: an DPE audiogram and a DPE input/output function. Noise picked up is reduced by averaging the DPE signals many times, yet causing each of the DPE signals that is averaged to be of the same phase a every other DPE signal. Random phase noise is reduced by the averaging process.

  • Patent number: 5658227
    Abstract: An exercise device (10) has a handlebar (30) with handgrips (32) for gripping by a user (U). An adjustment plate member (26) is mounted for pivotal movement about a pivot (28) on a fixed support plate member (18). A seat (58) supports the weight of the user U to resist to the rotation of the adjustment plate (26). A generally horizontal exercise movement is performed by pulling on the handlebar (30) and simultaneously pushing on foot pedals (70) on a foot frame (68) secured to the adjustment plate member (26). The horizontal exercise movement shown in FIGS. 1 and 2 can be easily converted to a vertical exercise movement shown in FIG. 3 at the discretion of the user (U) by changing the motion exerted against the handlebar (30) by the user (U).
