Title: On edge envelope stacking apparatus with adjustable registration surface
Inventor: BELEC ERIC A
IPC: B65H39/075
Filed: 1994-11-15
Abstract: In accordance with the present invention apparatus for stacking flat articles, such as envelopes, on edge, comprises structure for transporting the envelopes on edge along a transport path and a deck plate having an upper side adjacent the transport path. A vertical registration wall, which is mounted on the deck plate, defines a stacking bin in which the envelopes are stacked. A deflector, which is situated between the transporting structure and the stacking bin, pivots between a first and second position, wherein the first position allows the envelopes to be transported past the stacking bin and the second position deflects the envelopes into the stacking bin. There is an urge roller, located in the stacking bin between the deflector and the registration wall for urging the envelopes towards the registration wall. There is a spring loaded paddle slidably positioned in the stacking bin orthogonal to the registration wall and above the deck surface, for urging the stacked envelopes toward the urge roller. The registration wall is positioned for a particular size envelope such that a trail edge length of the envelope is approximately 1 1/2 inches, the trail edge length being the distance between the trail edge of the envelope and the engagement point of the urge roller to the envelope when the lead edge of the envelope is against the registration wall.

Title: Releasable panel for Overhead door
Inventor: TORCHETTI RINALDO
IPC: E06B9/92
Filed: 1995-04-19
Abstract: A panel member for use in an overhead door assembly has an outer frame defining a panel  slot, with  a  swingable  panel  seated  in  the  slot;  the swingable panel is hingedly mounted to the outer frame by a hinge,  retainers  on the outer frame hold the swingable  panel  in  the  panel  slot,  however,  under impact  the  panel  is  released  from  the  retainers, whereafter it is  free to pivot or  swing  about the hinge; after removal of the impact the swingable panel is  snapped back  into  the  retainers;  the  swingable panel  thus  accommodates  impact  forces  which  would otherwise dislodge the door from the track  assembly.
Patent CA-2149251-A1 (CA)
Title: Protective cap for nozzle
Inventor: GREEN GARREY D
IPC: F16L55/115
Filed: 1995-05-12
Abstract: A protective cap for insertion over a gas nozzle incorporates a simple, hollow housing for manual application over the nozzle. The nozzle, of the usual laboratory type, has a tapered body with a series of ribs, the ribs each having a gradual or shallow leading taper and a sharper, reverse taper on the trailing surface. The cap includes an elastomeric O-ring located within a groove in the mouth of the housing, the O-ring projecting radially into the housing so as to engage the ribs of the nozzle, as the copies applied. Due to the differences of taper angle between leading and trailing faces of the ribs, the application of the cap requires less force than its removal. The O-ring can vary in its size, durometer and cross sectional shape, to suit a variety of users.

Patent CA-2158579-A1 (CA)
Title: Serum Antioxidants as Predictors of Adult Respiratory Distress Syndrome
Inventor: REPINE JOHN E
IPC: C12Q1/56
Filed: 1994-03-18
Abstract: At the initial diagnosis of sepsis (6-24h before the development of ARDS), serum manganese superoxide dismutase (MnSOD) levels and catalase activities are increased in septic patients who subsequently developed ARDS compared to septic patients who did not develop ARDS. Increases in MnSOD and catalase may be used to predict the occurrence of ARDS in septic patients with the same sensitivity, specificity and efficiency as parallel assessments of serum lactate dehydrogenase (LDH) and Factor VIII levels. Evaluation of serum MnSOD and catalase as well as these other accessible markers facilitates identification of subsets of patients and allow prospective treatment of septic patients who are destined to develop ARDS.

IPC: G01V3/10
Filed: 1996-07-05
Abstract: A system for detecting metal targets located in a background environment such as the ground evaluates metal targets by processing components of signals at two or more different frequencies. A component of the received signal induced by the ground can be eliminated by subtracting signal components measured at two different frequencies. The received signal can be processed to account for changes in the background response with frequency. The type of an unknown target can be identified by processing background excluded components to produce data characterizing the target type.
