Title: Safety device and method for removal and disposal of medical needles
Inventor: HOGAN J MARTIN
IPC: A61M5/32
Filed: 1988-03-17
Granted: 1991-12-31
Abstract: ABSTRACT    A protective  device  and  method  for  the  removal  and disposal  of  spinal  needles.   The  protective  device is comprised of a needle pulling assembly upon which is slidably mounted an external housing.  In operation, a needle to be removed  from a patient  is  engaged  in  the  needle  cradle portion of the needle pulling assembly.  The external housing is moved into contact with the patient's skin and the needle is withdrawn by pulling on the pulling rod portion of the needle pulling assembly in a direction away from the patient.          The needle is withdrawn into the interior of the external housing, thereby covering the entire length of the needle.     The pulling assembly is then locked into place and the entire assembly including the withdrawn needle can be disposed of, thereby  avoiding  the  possibility  of  needle  pricks  by contaminated spinal needles.

Title: Folded protective hood having an oxygen mask
Inventor: ROEHLING HOLMER
IPC: A62B17/04
Filed: 1988-06-10
Granted: 1991-01-02
Abstract: Abstract of the Disclosure The invention relates to a protective hood having a viewing window and an oxygen mask equipped with a breathing-gas connection for an oxygen supply.  The protective hood is improved in that the oxygen supply is first established unhindered and the protective hood can be pulled over the head with a reliable manual movement when required without the oxygen supply having to be interrupted.  Such a protective hood is especially useable by passengers in an aircraft.  The protective hood is packed such that the hood is rolled up toward the front in four mutually perpendicular directions in the direction of the breathing-gas connection for the oxygen mask so that a rip loop holds the rolled parts together by means of a VELCRO closure.  The rip loop is attached to the hood in the region thereof corresponding to the nape of the neck.  For the required situation and while the user holds the oxygen mask in place on the face, the user need only pull on the loop thereby causing the rolled hood to unfold and the edge of the hood can be simply pulled over the head.

Abstract: UNIVERSAL VACUUM AND CLAMP SETUP FIXTURE    FOR COORDINATE MEASURING MACHINES                         ABSTRACT           The invention is an apparatus for and the method of clamping flexible items in a fixed position in relation to the measuring probe of a coordinate measuring machine.  A perforated rigid plate is attached to the working surface of the coordina-te measuring machine.  One or more hollow, rigid article holders are mated to the plate by use of suitable fastening mechanisms.  On the upper end of each hollow support holder for articles is a flexible suction cup.  A source of vacuum is provided to the article holders which is directed through the opening of the suction cup.  One or more stand-offs or spacers may be installed on the plate as well, to help position a part.  A part to be measured is then placed on the article holders and a vacuum is applied.          Coding of the position of each of the perforations on the plate allows for easy setup and reproducibility.  The stand-offs or spacers are equipped at one end with a mechanism to allow attachment to the plate, and at the opposing end with a mechanism to allow mating of the stand-offs or spacers together, or mating of them with the article holders.  In this fashion, the stand-offs or spacers can function to change the height of the article holders in relation to the surface of the plate, and can also function to restrict the movement of the article placed on the invention.  The method herein described includes the method of utilizing the features of the invention to affix an article to a coordinate measuring machine with good reliability and reproducibility.

Title: Auto rack side panel support system
Inventor: YOUNGBLOOD BERNARD J
IPC: B61D3/18
Filed: 1988-12-14
Granted: 1992-06-02
Abstract: AUTO RACK SIDE PANEL SUPPORT SYSTEM                 ABSTRACT OF THE DISCLOSURE Automobiles are transported on train cars called auto racks. These auto racks arc covered by galvanized steel panels that are mounted by brackets to the auto rack frame. The brackets and frame are typically formed of a metal other than galvanized steel and the interface between the two metals cause the panels to rust and crack. Applicant has solved this problem by coating the brackets with a nylon coating that prevents the panels from rusting. Brackets that are to be welded to the frame are left uncoated at their weld points but are coated elsewhere. The invention results in an auto rack panel support system that will prevent rusting of the side panels and allow them to be used for longer periods of time.

Abstract: The blockage module is designed to be mounted on air seeder seeding equipment.   Piezoelectric sensors extending into the flow tubes monitor flow by producing high  frequency  ringing  signals  when struck by seeds.     During a calibration step, the module will monitor each sensor and adjust the gain of the signal until the number of seed hits per second above a fixed voltage threshold is near a predetermined value.  Each sensor connected to the module will be similarly calibrated, and the cali-brated gain and hit rate will be stored.   It has been found that if a blockage or partial blockage occurs under these calibrated conditions, the number of hits above the fixed voltage threshold will be sharply reduced.   The reduced hit rate is compared to the calibrated hit rate, and an alarm is  generated if  the  reduction is  great enough.   Because  the  reduced hit rate is immediately detectable,  the response time to report a blockage is very short.
