Title: Strut with controlled variable damping rate
Inventor: HUDGENS BERNARD C
IPC: F16F9/46
Filed: 1988-08-24
Granted: 1992-06-23
Abstract: Abstract An apparatus for damping relative movement of parts.          The apparatus includes a cylinder defining a fluid chamber.          A piston is located in the fluid chamber and divides the fluid chamber into first and second fluid chamber portions.          The piston is connected to one of the parts and the cylinder is connected to the other of the parts.  The piston and cylinder move relatively in compression and expansion strokes to damp relative movement of the parts.  A fluid reservoir is in fluid communication with the first fluid chamber portion.  A first valve controls fluid flow from the first fluid chamber portion into the fluid reservoir upon movement of the piston and cylinder during a compression stroke.  A damping control provides a variable damping force resisting movement of the piston and cylinder during an expansion stroke.  The damping control includes a second valve movable with the piston for controlling the fluid flow from the second fluid chamber portion to the first fluid chamber portion.  The second valve opens by fluid pressure in the fluid second chamber portion.  A variable force is appled to the second valve to resist opening of the second valve.

Abstract: Description HOOK FOR HOPE USED TO PULL A BOAT                       INTO A DOCK                     Abstract of the Disclosure Disclosed is a hook which may be attached to an end of a rope and used to pull a boat into dock.  The hook has an elongated  shank  having  first  and  second  ends  and  an  end opening in the first end of the shank into which a rope may be received.  A single tine extends from the second end of the  shank and has a free end spaced from the shank.  The shank  has  a  substantially wide and  flat  surface directed towards the tine which together with the tine forms a hook throat.   The  first end of the shank,  from which the rope may extend, is  beveled  to form an obtuse angle with  the flat  throat  surface  of  the  shank.   When  the  hook  is attached to a rope and is thrown over an object,  the rope may be retracted  to pull  the hook  toward  the object such that contact of the angled  first end of the shank against the  object,  in  cooperation  with  the  weight  of  the  tine causes  the  hook  to  align  itself  such  that  the  tine will engage the object.

Abstract: ABSTRACT OF THE DISCLOSURE           An artificial ventilator includes a dome for covering the precordial and the sides of the thoraco-abdominal of a patient, a blower to be used for applying negative and positive pressures within the dome, a regulator for adjusting a pressure, and the like.  The valve switching device is controlled by a respiration detection system.  In the respiration detection system, a pyroelectric element is used as a respiratory sensor for detecting a temperature change rate caused by an inspired and expired air flow.  The temperature change rate signal obtained by the sensor is compared with a threshold value set by a variable resistor, the start timings of expired air and inspired air are detected in accordance with the comparison result, and air inspiration and expiration start timing signals are outputted.  Further, the artificial ventilator can be provided with various func-tions of forced respiration and intermittent deep breathing by means of a timer, synchronization only with air inspiration timings, reduction of frequency of respiration assistance for the intention not to use the ventilator in the near future, backup during apnea, and the like.  The artificial ventilator allows a physilogical respiration assistance matching the patient's physiological intention by synchronizing with the patient's respiration.  Thus, an effort and pain in breathing with a conventional mechanical ventilation can be avoided so that the artificial ventilator is suitable for a long term use and useful for a quick recovery of respiration function of an acute respiratory failure patient.

Abstract: ABSTRACT OF THE DISCLOSURE      A dual-polarization geometry for printed-circuit antennas, in which two layers of radiating elements and corresponding power dividers are provided, one set of power dividers being disposed orthogonally with respect to the other, so as to enable reception of two signals with orthogonal senses of polarization.  Either dual linear or dual circular polarization may be achieved through suitable  selection  of  radiating  elements.   Alternatively,  a quadrature hybrid may be coupled,  either externally or as an integral part of the antenna, to enable dual circular polariza-tion. Various shapes and types of radiating elements,  having patches or slots, may be employed in the various layers.  Fur-ther,  a gridded radiating element,  formed of a grid wherein a metallization region is etched selectively to yield a plurality of metal strips disposed parallel to each other with a predeter-mined separation,  may be used.   This element,  in contrast to known elements which employ solid metallization regions,  finds particular application in dual polarization geometries, wherein two signals are received simultaneously,  and enables improved performance over a wide bandwidth.  The gridded element also is applicable to single-polarization geometries.
