Title: Device and process for mixing a sample and a diluent
Inventor: PARRENT GEORGE B JR
IPC: G01N1/28
Filed: 1987-08-20
Granted: 1992-11-10
Abstract: A B S T R A C T              Disclosed is an effective dilution apparatus of simple construction which is easy to manufacture and use.  The sample liquid is passed through a non-wetting porous membrane from a reservoir of sample liquid to a flowing stream of diluent which is constantly flowing when the sample liquid penetrates the membrane under positive pressure differential from the sample side of the membrane.  The pressure differential can be suitably obtained both by means for exerting pressure on the sample liquids as for example on a stream of sample liquid on the entry side of the membrane as well as a reduction in pressure on the exit side of the membrane.  The passage of the sample liquid through the non-wetting porous membrane requires a minimum liquid entry pressure differential across the membrane to cause penetration through the pores and not the material.

Inventor: MORRIS PETER C
IPC: B41M5/50
Filed: 1988-01-28
Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE     An overhead transparency system which enhances the density of images printed on film by ink-jet techniques is provided.  The film is coated with a layer of a transpar-ent, hydrophilic material to a thickness which promotes controlled lateral diffusion of the printed ink.       The lateral diffusion is microscopically observed to begin within 1 minute after printing, eventually ceasing as the vehicle of the ink is sufficiently spread and eva-porated by the lateral spreading.  The optical density of the image increases as the ink diffuses, reaching a maxi-mum density that is considerably greater than otherwise possible without an ink-coating system.      Sheets of such printed transparencies are protected by insertion between sheets of a vapor permeable, water absorbent material such as cellolose acetate.

Title: Femoral compression device for post-catheterization hemostasis
Inventor: KURTH PAUL A
IPC: A61B17/00
Filed: 1988-04-28
Granted: 1993-04-20
Abstract: FEMORAL COMPRESSION DEVICE        FOR POST CATHETERIZATION HEMOSTASIS             Abstract of the Disclosure An improved femoral arterial or venous compressive device is comprised of a flexible pelvic apron positioned over the femoral vessels within the human pelvis. The pelvic apron is placed in position by means of a hip strap. The hip straps are led from the pelvic apron upwardly over the hip points, around the small of the back and down over the opposing hip point back to the pelvic apron. The pelvic apron thus hangs from the hip points of the pelvis much like an apron. A shaped mass or pellet is attached to the under side of the pelvic apron over the incision site of the femoral vessel. An elastically extensible groin strap is then attached to the pelvic apron in the proximity of the shaped mass and drawn tightly through the groin, around the back of the leg, under the buttocks and back upwardly to the pelvic apron in the proximity of the shaped mass. As a result, the tensile force is applied by the groin strap across the pelvic apron up to the hip point and also around the leg. The shaped mass is forced by the tourniquet action of the groin strap and pelvic apron in combination downwardly into the pelvis, thereby compressing the underlying femoral vessel and thus assisting in stanching any blood flow or fluid leakage.

Abstract: A  photographic  traffic monitoring device  comprises  a sensor  responding to passing vehicles, for example,  an induction  loop  imbedded  in the  road  for  monitoring traffic  lights  or  a  Doppler  radar.  From  a  signal evaluation  it is determined whether a detected  vehicle has  violated a traffic regulation, e.g.  exceeded  the allowed  maximum  speed  limit. When such  a  violation takes  place, a camera is automatically released and the monitored  vehicle is photographed. In order to  collect data  for  statistical  purposes  about  traffic  events obtained  with  such  devices,   a  memory  function  is provided.  This function records events detected by  the device,  events  which are not restricted to  violations of traffic regulations.
