Chair lift

Most and Bruckner (1936) found human tracks to be complex. A track contains a human species odor and an individual odor, both extruded through boots, but also the odors of crushed plants, disturbed soil, and leather or other shoe material. Dogs still tracked correctly after removal of one or several of these components. To separate the track components, the authors built a chair lift and a track wheel (Fig. 13.5). The rim of the metal wheel (approximately 2m in diameter) carried raised replicas of shoes at stride intervals. Pulled over the terrain, the wheel makes a track of crushed plants and disturbed soil without human scent. The lift consists of a chair suspended on a steel cable about 1.5 m above the ground. Although a person riding this chair leaves no foot imprints or disturbed soil, he/she still sheds odorous rafts of skin cells. A trained dog uses one or the other of these track components, as terrain and surface change. 

As the rocket ship, guided by superfast superconducting computers, each the size of a sugar cube, shoots out of the range of earth s gravity, Electric Man presses a button in the arm of his easy chair. The chair lifts a few inches off the floor and then, responding to the touch of another... 

Chemical equilibrium is a dynamic process. As such, it can be likened to the movement of skiers at a busy ski resort, where the number of skiers carried up the mountain on the chair lift is equal to the number coming down the slopes. Although there is a constant transfer of skiers, the number of people at the top and the number at the bottom of the slope do not change. 

Based on the theoretical predictions and the experiments described above, in 1995 dynamic absorbers were installed on chair lifts in Japan. This is the first application of dynamic absorbers for ropeway carriers in the world. An... 

Safety codes and standards for the design, construction, installation, operation, inspection, testing, maintenance, alteration, and repair of elevators, dumbwaiters, escalators, moving walks, material lifts and dumbwaiters with automatic transfer devices, wheelchair lifts, and inclined-stairway chair lifts. 

Today, hydraulic power is used to operate many different tools and mechanisms. In a garage, a mechanic raises the end of an automobile with a hydraulic jack. Dentists and barbers use hydraulic power to lift and position their chairs. Hydraulic doorstops keep heavy doors from slamming. Hydraulic brakes have been standard equipment on automobiles since the 1930s. Most automobiles are equipped with automatic transmissions... 

Massage chairs, special lifts for bathtubs, hospital beds, etc. all have electronic adjustments that can be controlled by reed sensors. In applications like these, no special voltage or current is necessary. Therefore, there is no risk of dangerous electric shock. 

I once suggested to the Maestro that he obtain a chair on wheels, but he does not need it while he has Bmno, who is a mute, a litde larger than Michelangelo s David. He happily lifted Nostradamus, chair and all, and carried him through to the dining room. He loves to be useful. 

Miss Muxdroozol sits back in Bob s massaging, high-back, executive leather chair. She smiles as the five built-in battery-powered massaging units begin to work on her clavicle areas. For a moment, Bob s mind wanders as he thinks of the chair s pneumatic gas lift, providing instant seat height adjustment. 

My father is at his desk, and his wig, a vast, fuzzy affair, already hangs on the back of his chair. It helps him think and is worn so that it can be snatched off when he gets excited. He is sixty-three, but he still has lots of silver hair, which he strokes from time to time with his left hand. He takes up very little space but bums so fiercely that he has only to lift a finger for everything to change. I think of him as the sun and me as a little planet held in place by the force of his intellect.

Back injuries are also caused by improper lifting and ergonomically incorrect office chairs. To avoid these injuries, employees should be instructed in proper lifting techniques and provided with ergonomically correct office equipment.
