Title: Dual-mirror virtual image display for vehicle instrument cluster
Inventor: HEGG RONALD G
IPC: G02B27/01
Filed: 1990-11-26
Granted: 1994-11-01
Abstract: A virtual image display for vehicles that includes an  image  source  for providing  imaging  illumination,  a negative power aspheric off-axis mirror responsive to the image source imaging illumination for providing diverging reflected  imaging  illumination,  and  a  positive  power aspheric  off-axis  mirror  responsive  to  the  diverging imaging illumination  for providing converging reflected imaging illumination that produces a virtual image of the image  source  observable  by  the  vehicle  operator  at  a viewing distance that is greater than the optical path travelled  by  the  imaging  illumination  from the  image source and the eyes of the vehicle operator.  The use of a negative power mirror with a positive power mirror pro-vides  for  a  compact  display  system which  can  include relatively large image sources such as electromechanical gauges, and which provides for a relatively far viewing distance and a relatively large field of view.

Granted: 1994-09-20
Abstract: A combined surgical drainage device and autotransfusion apparatus is provided in which a drainage device having a conventional collection chamber and suction regulating system may be readily converted into use as an autotransfusion system.  The drainage apparatus has a fluid retention chamber disposed immediately beneath the inlet and a fluid outlet is provided in the bottom wall of the retention chamber with a spring  pressed  closure  therein  so  that  a  nozzle  on  a collapsible autotransfusion bag may be inserted into the fluid retention chamber.  The autotransfusion bag is collapsible and is provided with removable spreader means to maintain the bag in an expanded condition.   When suction is applied to the drainage device, the interior of the autotransfusion bag is maintained  at the  desired  suction  level.    With  a  tube connected to the inlet tube on the drainage device with the distal end of the tube at a surgical site, blood is drawn through the tube into the fluid retention chamber and this blood passes into the autotransfusion bag.  When the bag is filled,  it  is removed from the drainage device and the spreaders are removed from the bag so that when the blood is reinfused to the patient through the same passageway through which the blood was fed to the autotransfusion device, the bag will collapse without any air passing into the autotransfusion bag.

Abstract: A drill bit for use in drilling a well bore comprises a main drill body (l0) adapted to be rotated about a substantially vertically disposed axis of rotation (20) and having therein a duct extending longitudinally along such axis, for supplying a drill fluid under pressure to the well bore. At least one generally circular, rotatable cutting discs (34, 36, 38) are mounted on the outside of the main drill body (10) at equally spaced locations, with the cutting discs each having cutting elements (35, 37, 39) disposed in a ring-shaped array. Each of the cutting disc (34, 36, 38) has an axis of rotation disposed at an acute angle to the vertical centerline about which the main drill body rotates. The axis of rotation of each cutting disc (34, 36, 38) is slightly offset laterally in a rearward direction from the centerline (20) of the main drill body (10), thus to cause the entire bit to be placed in a non-equilibrium position with the rotation of the main body enabling the cutting disc (34, 35, 38) to be positioned to be particularly effective and aggressive in cutting the well bore.

Abstract: Heat is applied to a solid or semi-solid material in a cylindrical container in such a way that a precise, predetermined amount of heat is transferred to a horizontal layer of the material until it softens sufficiently to allow the heating element to sink into the material where it will heat the next layer.  The container is rotated about a vertical axis, and a horizontally-oriented heating element is lowered into contact with the material to apply heat to a horizontal layer.  The heating element is lowered through the material in a controlled manner to heat progressively lower layers within the container, until the whole container has been heated.  The heating element may be heated by pumping hot water therethrough, or by other means.  A container of hot liquid may be cooled in a similar fashion, by gradually raising a cooling element from the bottom of the container.
