An orthopedic insole capable of being inserted into a shoe or the like for relieving and/or treating skin disorders and/or calluses and/or metatarsal pain comprises at least one semi-rigid corrective element capable of producing an inner metatarsal support, over the rear portion of the head of the first metatarsal, and/or a median metatarsal support, over the rear portion of the second and/or third and/or fourth metatarsal head, and/or an external metatarsal support, over the rear portion of the fifth metatarsal head.

A positive displacement pumping system for use in deep wells includes a drive system and one or two pumps. In the preferred embodiment, the drive system includes an electrical motor, a speed reducer, and a rotary-to-reciprocal motion converter. Alternatively, the drive system includes a windmill, a variable transmission, and a counterbalance. The counterbalance can be either weights or a second alternating pump. The pumps include a central hollow discharge tube and one or more vertically aligned pumping chambers in fluid communication with the central discharge tube. Within each pumping chamber, a valve arrangement, which includes a piston or shuttle member and fluid intakes, causes fluid to fill and then drain from the pumping chambers as the central hollow discharge tube reciprocates. In operation, the drive system causes the central hollow discharge tube in the pump to reciprocate and thereby cause the fluid to travel from each pumping chamber into to the central discharge tube. In the preferred embodiment, fluid is pumped on both the upstroke and downstroke of the central discharge tube. Alternatively, fluid is discharged on only the upstroke. Fluid from the central discharge tube is discharged from the pump into a discharge field. The amount of fluid discharged on each stroke depends on the number and size of pumping chambers and the length of the stroke. A greater number of pumping chambers causes a greater discharge of fluid at a higher velocity into the discharge field.

A system and method of generating water from air in a cost effective manner is provided. In some embodiments, the water generating apparatus uses a combination of rotating pre-loader wheels of solid desiccants, fans, mechanical systems such as Vapor Compression Cycle (VCC) or Peltier coils, filtration and mineral addition units to create a cost effective system for generating water from ambient air. In other embodiments, the water generating apparatus include smart controls for optimizing water production as per consumer requirements at times of the day when utility rates are low.

An automobile neck pillow relates to an automobile seat articles technology field, which adopts a key technology truly adapted to human mechanical physiological curves and makes a multiple choice about materials of a core body and an elongated housing and a scientific measurement about shapes and sizes thereof to make the core body and the elongated housing match with each other, wherein the core body is soaked in medical liquids of health care to provide health care and healing to the neck, the core body is attached with a bamboo charcoal fiber cushion, an infra-red cloth, or a negative oxygen ion cloth while integrally being sprayed with perfume, and a brace provided in the elongated housing is mounted between a seat and a head cushion by a longitudinal fixation, a transverse fixation, a combination of longitudinal and transverse fixation, a head-sleeving fixation, or an integral fixation with the head cushion.

Apparatus and method to improve flow of liquid anhydrous ammonia from a portable liquid NH₃ tank in cold temperatures includes an air compressor coupled to the vapor port of a portable liquid NH₃ tank used to supply liquid anhydrous ammonia to an anhydrous ammonia fertilizer applicator. The air compressor injects compressed air into the tank to maintain head pressure within the tank at between 80 and 150 psi. to facilitate flow of liquid NH₃ from the tank to the applicator when atmospheric temperatures are low as well as when the level of liquid NH₃ present in the tank declines.

A cyclic adsorption process is provided, the process containing one or more adsorber vessels undergoing the steps of at least pressurization and depressurization and driven by one or more variable speed centrifugal machines operating under acceleration and deceleration conditions and adjusted to the steps, vessel size, and process conditions employed, wherein the process cycle time is greater than the ratio of the change in inertia, defined the maximum energy that can be lost during a cycle due to inertia changes, to 0.3 times the total power of the one of more centrifugal machines that would be consumed in the absence of inertial effects.

An apparatus and method to improve delivery of liquid anhydrous ammonia from a portable liquid NH₃ tank in cold temperatures includes an air compressor coupled to the vapor port of a portable liquid NH₃ tank used to supply liquid anhydrous ammonia to an anhydrous ammonia fertilizer applicator. The apparatus can include an actuator to relieve the tank of compressed air after the tank is empty of liquid anhydrous ammonia.
