Abstract: A test method for determining adulteration by diuresis or the addition of a diuretic, which uses creatinine and specific gravity measurements to determine a normalized creatinine value for comparison with expected normalized creatinine values for the substantially diuretic-free population.

Abstract: Horse riding apparel for training proper equestrian positioning of a rider for competition and casual riding, in which a hat, a shirt, and a pair of pants worn by the rider include signalling members for visually communicating the angulation and the posture of the rider while riding to an instructor so that the instructor may observe the rider and provide corrective guidance.

Abstract: A threshold for a covered cat litter box having a side entry comprises a stand supporting an elevated cat landing field. A ramp having a rough litter-dislodging surface extends downwardly from the cat landing field. A barrier is provided for barring cats from jumping onto or off the sides of said ramp. Upon setting the threshold with the ramp accessible to the litter box entry cats may ingress and egress the liter box only via the threshold rough, liter dislodging ramp and landing field which dislodges litter from the paws.

Abstract: An air compressed gun (10) is provided having a stock (11), a barrel (12), a trigger (13) and a manual air pump (14). The gun also has a control valve (200) which controls the flow of compressed air into a magazine (202). The control valve includes an external tube (204), an internal tube (205) reciprocally mounted within the external tube, and a plunger (206) reciprocally mounted within the internal tube.

Abstract: A pipeline recovery system (10) is disclosed having a recovery vessel (11) with an upper deck (12) and a pivotal pipeline ramp (13) mounted to the bow of the vessel. The system also includes a pipeline support bed (22) having a middle portion (23), two grated portions (24) straddling the middle portion, and a liquid collection trough (25) coupled to a seawater contaminate separator (26). A pipeline positioning winch (30) is mounted to a rearward end of the pipeline support bed. A length of a pipeline (P) is lifted from the seabed and onto the support bed where it is secured by a pair of clamping arms (40) and a vertical clamp (41), and cut with a pipe shear (42).

Abstract: An air compressed gun (10) is provided having a pressure chamber (35), a moveable magazine (18) and a conduit conveying pressurized air from the pressure chamber to the magazine. The conduit has a resilient sealing gasket (42) which is reconfigurable between a relaxed configuration and an expanded configuration with the presence of pressurized air.

Abstract: A method of monitoring compliance of a patient that has been placed on a medication maintenance program with a prescribed medication dosage by determining a normalized urine methadone concentration. An unadulterated urine sample is obtained from the patient. The urine methadone concentration and urine specific gravity are measured. The normalized urine medication concentration is calculated as a function of the measured medication concentration in the urine and the urine specific gravity. The calculated normalized urine medication concentration is compared with an expected medication concentration value for the patient for the maintenance program prescribed to determine any significant differences therebetween as an indication of noncompliance. Alternatively, a urinary-parameter normalized urine medication concentration is calculated as a function of the measured medication concentration in the urine, the urine specific gravity and at least one selected pharmacokinetic parameter of the medication.

Abstract: A liquid metering and injecting device has a reservoir (10), a pump means (11) and a delivery tube (13) in fluid communication. A motor (19) of the pump means (11) is controllably operated so that a plunger (18) is reciprocated within a cylinder (17). A valve means (32) directs the flow of liquid from the reservoir (10) to the pump means (11) as the plunger (18) is retracted and from the pump means (11) to the delivery tube (13) as the plunger is extended without backflow. With this construction, a selected amount of liquid (14) is periodically metered and injected to a patient.

Abstract: A method and apparatus is disclosed for mounting constructing a flexible a tubular fitment (10) to a flexible container (11) and to the resulting product. The fitment is mounted upon a mandrel (24) having an extendable bearings in the form of an annular array of balls (27). The mandrel supporting the fitment is positioned within the container body (11) and the assembly positioned in heat sealing dies (33,34) having an annular channel (35) sized to receive the fitment. The dies have a groove (36) extending from the channel. The balls are then outwardly extended into the groove and the mandrel rotated to cause the balls to orbit in a circle and seal the fitment to the flexible container oven an annular protrusion (38).

Abstract: A balanced strand includes a fibrous core about which load bearing fibers are twisted. The fibrous core has an elongation factor of at least 10% and comprises approximately up to 30% of the material volume of the strand. The load bearing fibers have an elongation factor less than the fibrous core and a strength of at least 15 g denier. The load bearing fibers comprise the remaining strand material volume.

Abstract: A forced flow viscosity measuring apparatus includes within a housing (13), a thermostatic air chamber (11), a measurement capillary (38) and a needle (60) in fluid communication with the capillary each contained in the chamber, and a variable speed drive mechanism (14) which dries such needle into the liquid at a speed that maintains the pressure differential constant across the length of same measurement capillary to which is attached a pressure measuring device (30) and the needle (60), and a control circuit (50). The control circuit (50) computes viscosity as a function of sensed needle (60) velocity, sensed constant pressure differential and the parameters of the capillary.

Abstract: A segmented residential front loading refuse collection vehicle for collecting recyclable waste materials includes a frame and bed pivotally mounted on the frame, the bed having a front, a rear, a top, and a bottom. A fixed wall extends vertically from the bed bottom toward the bed top and extends longitudinally from the bed rear toward the bed front. A movable wall cooperates with the fixed wall for dividing the bed into side-by-side compartments. A single compactor blade is positioned partially within each of the side-by-side compartments for compacting the compartments in tandem.
