Title: Hydraulic system for an industrial machine
Inventor: JOHNSON STEVEN H
IPC: E02F3/32
Filed: 1988-02-02
Granted: 1991-01-15
Abstract: HYDRAULIC SYSTEM FOR AN INDUSTRIAL MACHINE        Abstract of the Disclosure An excavator has a number of different hydraulically powered functions that are controlled by a closed center hydraulic system that features a pair of variable displacement, engine driven hydraulic pumps, the displacement of which is responsive to the demands of the system.  The flow to the various hydraulic motors is controlled by pilot operated load sensing control valves that direct fluid pressure to a load sensing line when one of the hydraulic motors in the system is being operated. The load sensing line is connected to the control system of the pumps to place the pumps in stroke when a flow of pressurized fluid is required.  The flow of the load sensing pressure to the controls for one of the pumps can be optionally disconnected to place said pump in a standby condition and thereby reduce the flow capacity of the hydraulic system at the option of the operator.

Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE    A film cassette opener for unloading a film from, and/or loading the film in, a film cassette capable of accommodating the film.  A pair of elongated members are disposed parallel to each other on the opposite sides of a path which enables the film cassette received by the film cassette opener to be moved to a position at which the film can be loaded and/or unloaded.  The pair of elongated members are arranged to guide the film cassette along the path by holding opposite sides of the film cassette between them.  Also, the present opener is arranged so as to press and move at least one of the elongated members which hold the film cassette therebetween toward the other.  Accordingly, since the film cassette is firmly held, it is possible to positively move the film cassette.

Title: Electronic sensing and control circuit
Inventor: TUTTLE WILLIAM C
IPC: A61G5/04
Filed: 1988-06-15
Granted: 1992-07-14
Abstract: ELECTRONIC SENSING AND CONTROL CIRCUIT An electronic sensing and control circuit is provided which includes a sensing plate and means for charging the sensing plate to a value dependent upon the capacitance existing between the sensing plate and a remote object. The capacitance between the sensing plate and the object varies with the distance of the object relative to the sensing plate. The sensing plate is periodically discharged and charged producing a useful current proportional to the capacitance and varying with the distance between the sensing plate and the object. Two sensing plates are used to provide first and second signals. The first and second signals are subtracted to derive a lateral displacement signal and added to derive a distance signal. The lateral displacement signal and the distance signal can be used to control the forward, reverse and turning motion of a motorized wheelchair.

Abstract: ABSTRACT OF THE DISCLOSURE    A radial turbine of a variable area nozzle type which is suitable for use as the exhaust turbine of a turbocharger for an automotive internal combustion engine requiring a quick response and a wide operating range.  This turbine comprises at least two groups of variable area nozzles which may be, for instance, defined by moveable vanes, and can be individually controlled for each group to vary their sizes.  By opening the variable area nozzles of the first group while the variable area nozzles of the second group are kept closed, a sufficient supercharging effect can be obtained even when the fluid flow rate is small.  By opening the variable area nozzles of both the groups, the resistance to the fluid flow can be reduced and the creation of excessive back pressure at the inlet to the turbine can be avoided even when the fluid flow rate is large.  In this way, not only the operating range of the turbine can be expanded but also the control accuracy particularly in small nozzle opening condition can be improved.

Abstract: ABSTRACT OF THE DISCLOSURE:          This invention relates to a structurally-improved racket handle designed to increase the area of the palm in contact with the racket handle thereby allowing a better grip than presently available racket handles.  This affords greater power transfer while returning serves,  volleying, serving,  and other strokes due to the provision of an oblique surface 11 cm.  in length that extends from the bottom end of the racket handle in alignment with its central axis and is beleved from the butt in a graduated, constant,  or curved manner.   The resulting graduated, constant,  or curved surfaces yields a naturally formed wedge-shaped edge that fits snugly into the muscles and bones of the palm and muscles of each finger,  and enables the palm to naturally assume a  tight,  circular,  yet comfortable grip.   The graduated,  constant,  or curved surfaces that slant upward from the butt of the racket handle  offer  support  to  the  hypothenar  eminence,  os pisiforme,  and humulus  oss'a  hamate  against  pressure generated during play, making it easier to maximize serving power and other techniques.

Title: Light source with gradually changing intensity
Inventor: HAAB WILLIAM G
IPC: H05B37/02
Filed: 1989-07-20
Granted: 1993-03-02
Abstract: ABSTRACT           A device and method of awaking a sleeper includes an alarm clock coupled to a control circuit for controlling the power provided to a lamp.  After the alarm clock wake-up signal is provided, the light intensity emitted by the lamp slowly, smoothly and gradually increases.  The time interval over which the light intensity increases is selectable by the user but will usually be in the range of thirty minutes to an hour.   The circuit for increasing the light intensity is designed to ensure that the intensity increase is smooth, especially at the beginning of the wake-up cycle.   A photo resistor adjacent an LED is part of a parallel resistive network which lowers the firing angle of a triac to increase the intensity of the light.   The LED is biased in the on state to minimize transients as the current through the LED varies.   The use of a parallel resistive network causes the firing angle to change more slowly when the light is very dim then when the light intensity is bright because the human eye is more sensitive to light  intensity variations when the background light level is low than when it is high.
