Title: Method and system for absolute activity determination  of radionuclides
Inventor: POCHWALSKI KRZYSZTOF K
IPC: G01T1/178
Filed: 1978-05-16
Granted: 1981-08-04
Abstract: Abstract of the Disclosure A method and apparatus for absolute activity determination of radionuclides, especially of low maximum energy pure beta-emitters as for instance 3H, 63Ni, 14C, 35S.  The application of the invention can also be extended for activity determinations of other radionuclides, for example of those disintegrating through the electron capture.  The method contemplates producing pulses of various multiples of coincidence simultaneously, and correlating the counts of the pulses to obtain a measure of the absolute activity.  This is achieved by providing a scintillation head containing at least three photomultipliers optically coupled to the scintillator and the source whose activity is to be measured.  The outputs of the photomultipliers are connected via amplifiers to coincidence gates having two and three inputs. The outputs of coincidence gates with two inputs are connected to a summing circuit whose output constitutes the first output of the system, the output of the gate with three inputs constituting the second output of the system.

Abstract: ELECTRONIC TRANSMISSION CONTROL               Abstract of the Disclosure A control for the automatic shifting of a multi-ratio power transmission.  A memory is provided and programmed with the optimum vehicle speed shift points for upshift and downshift from each gear of the automatic range.  The actual speed of the vehicle is periodically sampled, and each time it is, such speed is compared with the shift points for the gear which the transmission is in to see if a shift from such gear should be made.  If it is determined from the speed sample that an upshift should be made, then the upshift speed points of higher gears are examined with reference to such speed sample to find the gear to which the transmission should be upshifted, i.e., the gear just above the highest gear having an upshift speed point which is less than the sampled speed. Having found such gear, the transmission is shifted thereto. Correspondingly, if it is determined from the speed sample that a downshift should be made (or can be made, in the event of a forced downshift condition), the downshift speed points of lower gears are examined with reference to such speed to find the gear to which a downshift should be made, i.e., the gear just below the lowest gear having a downshift speed point above the sampled speed.  At any time, the operator may set any gear in the automatic range as the highest gear so that the transmission will not upshift beyond such gear.

Abstract: APPARATUS FOR TRANSFERRING ELONGATED  ARTICLES FROM A SINGLE FILE SUPPLY INTO PRODUCT BUCKETS OF A CARTONER            Abstract of the Disclosure Apparatus for transferring elongated articles into the product buckets of a cartoner.  The articles are conveyed single file and are diverted by a primary diverter into two diverter conveyors.  The articles are thereafter pushed from the diverter conveyors into left and right accumulator stations onto conveyors moving transversely in opposite directions.  The accumulator conveyors hold the articles side-by-side at the downstream end of the accumulator conveyors.  A pusher bar pushes a group of articles from their ends longitudinally off the accumu-lator conveyor onto a dead plate which overlies the cartoner product bucket conveyor.  A sweep bar sweeps the articles off the dead plate into the product buckets.  The dead plate has a finger which projects alongside of the dead plate over which the ends of the articles ride so as to cause the articles to drop into the product buckets one end at a time, thereby providing better control over the position and orientation of the articles in the product buckets.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a disposable contraceptive in which a first member engages the vaginal vault and a second member, secured to the first member, engages and closes the cervical open-ing.  The first and second members are substantially discoid, with the second member smaller in discoid area than the first.          The second member is a generally impermeable sponge-like material which is lubricated to aid in adhesion and closure of the cervix.          The first member is generally resiliently closable so that the overall dimension of the contraceptive may be reduced in size for insertion into the vaginal vault.  The first member is defined at least by opposed anterior and posterior portions which engage the respective anterior and posterior portions of the vaginal vault.          The second member is coupled or joined to the first member at the posterior portion.        In one embodiment, the second member is a sponge joined to a film.  The film is held in position to define the first discoid member surface by a rim.        In other embodiments, the first and second members are resiliently joined at the posterior portion so as to urge the second member into positive engagement with the cervix.  Thus, a finite resilient nylon filament is bent into a figure 8 and covered with a soft, yieldable, foam plastic covering.  By folding at the intersection of the upper and lower loops, the contraceptive is formed.  In another example, a liner of resilient plastic in the shape of conjoined circles in covered by a soft, flexible, plastic envelope.  In yet another example, an annular discontinuous rim is covered by a foam plastic.  The rim has an integrally formed tongue extending therein and about, to which may be secured (by any well known means) a sponge-like impermeable plastic second member.
