Title: Process for the production of lactams
Inventor: GRIFFITHS GARETH DR
IPC: C07D211/86
Filed: 1992-09-11
Abstract: .beta.,.gamma.-unsaturated .delta.6-lactams, especially 2-azabicyclo[2.2.1]hept-5-en-3-one, are produced by a Diels-Alder reaction of 1,3-dienes with sulfonyl cyanides and subsequent hydrolysis. The sulfonyl cyanides are formed in situ from cyano chloride and the corresponding sulfinates.    By the renewed reaction of the sulfinate formed in the hydrolysis of the Diels-Alder adducts with cyanogen chloride, the sulfonyl cyanides are regenerated and a catalytic cyclic process results, 2-Azabicyclo[2.2.1]hept-5-en-3-one is a starting compound in the synthesis of antiviral nucleoside analogs.

Title: Low power complementary mosfet digital signal buffer circuit
Inventor: SANDHU BAL S
IPC: H03K17/687
Filed: 1992-10-15
Abstract: ABSTRACT OF THE DISCLOSURE A low power complementary MOSFET buffer circuit includes an input complementary MOSFET inverter with a plurality of serially coupled diode-connected complementary MOSFETs and an output complementary MOSFET inverter.  An input digital signal drives one of the input inverter's MOSFET gates, and passes through the diode-connected MOSFET to be biased, or level-shifted, prior to driving the input inverter's other MOSFET gate.  Driving the input inverter's MOSFET gates with both the input digital signal directly and its biased equivalent ensures that, when each of the input inverter's MOSFETs is turned "off" in accordance with the logic level of the input digital signal, it is turned off more fully, thereby minimizing power dissipation.  The inverted digital signal outputted from the input inverter drives both of the output inverter's MOSFET gates.  The original input digital signal also drives one of the output inverter's MOSFET sources, whereby the low-to-high transition time of the output digital signal is reduced.

Filed: 1993-05-03
Abstract: A blood sample collection apparatus includes a removable plug adapted to fit within the open end of a blood collection tube.  A vacuum tube extends through the plug for evacuating air from the collection tube.  A pickup tube protrudes outwardly from the plug for supplying blood to a drop tube extending downwardly from the plug with its lower end positioned within the collection tube substantially below the lower end of the vacuum tube.  A primary filter is sealed against the underside of the plug to filter the air drawn through the vacuum tube by a portable hand-held vacuum source.  The primary filter is a hydrophobic microporous membrane operative to allow airflow therethrough but to block liquid flow therethrough.  A secondary filter is operatively interposed between the vacuum tube and the vacuum source  for  increased  safety.          Installation of the secondary filter bypasses a bleeder port which renders the apparatus inoperative in the absence of the secondary filter.
