Abstract:

A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.

Abstract:

A manufacturing process of a construction strip includes the steps of (a) evenly mixing a predetermined amount of paint, talcum powder and volatile agent to form a plaster form coating mixture; (b) gradually passing an elongated strip body through an extrusion passage of an extrusion mold, wherein a uniform surrounding clearance between an interior wall of said extrusion passage and said strip body; (c) continuously injecting said coating mixture into said extrusion passage of said extrusion mold in order to fill said surrounding clearance, so that a uniform protective coating is evenly coated on said longitudinal surfaces of said strip body while said strip body is extruded from said extrusion mold; and (d) drying said protective coating to form a hard and durable protective coating shell integrally wrapped around said strip body.

Hugo S. Ferguson - Clearwater FL

Assignee:

Dynamic Systems, Inc. - Poestenkill NY

International Classification:

F15B 1524

US Classification:

92 131, 92 137

Abstract:

Apparatus, and an accompanying method for use therein, that utilizes working and stopping servo-controlled hydraulic pistons wherein the stopping piston acts as a controlled mechanical stop for the working piston. Both pistons are spaced apart along and coaxially arranged around a common shaft, with each piston moving in a separate cylinder. The working piston is securely attached to the shaft, while the shaft moves through a central, longitudinal bore of the stopping piston. The stopping piston effectively âfloatsâ in its cylinder and produces a greater force than the working piston. A radially extending stop element, situated on the shaft, has a surface configured to abuttingly engage with a complementary surface on the stopping piston such that the stopping piston, once appropriately positioned, controllably stops continued movement of the working piston in a very short time and over a very short distance with little strain induced in the apparatus.

Abstract:

Alpha rhythm brain waves are related to mental and physical relaxation and healing. Based on the studies of bionics, this invention relates to inducing oscillatory alpha rhythm to the human body, and relates to the means of the alpha rhythm machine applied to human body. Research of the alpha rhythm of human brain wave patterns and EEG has indicated special recorded data of alpha rhythm brain waveform which is the bearing of the proper biological information of relaxing and healing. The apparatus was developed and built to construct and release the simulated human brain alpha rhythm signals which are at the frequencies ranging 8 Hz–14 Hz and at the amplitudes altered in high or low. Both the frequencies and the amplitudes are changing at a non-stationary random order in the duration of the event, respectively. The electrical signals are transformed via a transducer, into three forms of energy, 1, alpha rhythm electromagnetic energy and alpha rhythm interfering static magnetic energy; 2, alpha rhythm sub-audio acoustic oscillatory energy; and 3, alpha rhythm mechanical vibrational energy. The combining energies from the apparatus can benefit the whole human body or only the area affected by illness, for example, treating men's prostate problems or treating sleep disorders.

Abstract:

Activation of electrogenic pump molecules can be realized by a dynamic entrainment procedure which includes two steps: synchronization of individual pump molecules to work at the same pumping pace, and gradual modulation of the synchronization frequency. Na/K pump molecules were used as an example in a physiological operating mode by applying the concept of an electronic synchrotron to the biological system. It was shown that individual Na/K pump molecules can be synchronized by a well designed oscillating electric field. The synchronized pump currents show separated inward and outward pump currents and a magnitude ratio of 3:2 reflecting stoichiometric number of the pump molecules.

Abstract:

Activation of electrogenic pump molecules can be realized by a dynamic entrainment procedure which includes two steps: synchronization of individual pump molecules to work at the same pumping pace, and gradual modulation of the synchronization frequency. We studied synchronization of the Na/K pump molecules in a physiological running mode by applying the concept of an electronic synchrotron to the biological system. Both theoretical analysis and experimental results showed that individual Na/K pump molecules can be synchronized by a well designed oscillating electric field. The synchronized pump currents show separated inward and outward pump currents and a magnitude ratio of 3:2 reflecting stoichiometric number of the pump molecules.
