Patent CA-2091296-A1 (CA)
Title: Brine recycling method and an apparatus therefor
Inventor: MIZUTANI MASUMI
IPC: B01D37/03
Filed: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE     A brine recycling method wherein the used brine containing metal ions is added with a reaction agent to provide agent-added brine.  The reaction agent is of a kind which, when it is reacted with the metal ions produces an insoluble substance, excluding an oxidant which, when reacted with oxygen, produces metal oxide. The agent-added brine is subsequently filtrated with the use of a microporous filtration membrane having an average pore size within the range of 0.005 to 1 µm.  A brine recycling apparatus is also disclosed which includes a filter module containing a filtration membrane having an average pore size within the range of 0.005 to 1 µm.  The used brine is, after having been added with the reaction agent, supplied through a supply passage into the filter module.   The filtrate is then removed from the filter module through a recovery passage.

Title: Apparatus for automatically inducing fibrillation
Inventor: MEHRA RAHUL
IPC: A61N1/38
Filed: 1991-11-12
Abstract: An automatic fibrillator for inclusion in an implantable defibrillator. Fibrillation induction takes place while the patient's heart is beating at a known rate, and the fibrillation inducing pulse is delivered at a time based on the expected or measured natural refractory period of the patient's heart, at the heart rate in effect during fibrillation induction. In its preferred embodiment, fibrillation induction takes place during overdrive pacing, and the timing of the pulse takes place using an overdrive pacing pulse as a time reference. The period between the pacing pulse and the fibrillation inducing pulse may be determined as a function of actual measurement of the patient's refractory period, either directory, or by means of measurement of the Q-T interval of the patient's heart.

Patent CA-2099733-A1 (CA)
Title: Overcurrent protection device
Inventor: LAGREE JAMES L
IPC: H02H3/093
Filed: 1993-06-29
Abstract: A microprocessor based overcurrent trip unit in-cludes an analog circuit for monitoring phase currents in the electrical interrupting device. The analog circuit is adapted to interface with the microprocessor over a range of selectable setpoints for instantaneous tripping and at the same time accurately monitor the phase currents even during a condition when the current sensing transformers are saturated. The overcurrent trip unit also allows the function of the long time delay characteristics of protec-tion curve to be varied in order to provide better coordi-nation with the characteristics of other overcurrent trip-ping devices in an electrical distribution system, such as a current limiting fuse, thereby enhancing the overall reliability of the system. For example, the function may be varied to provide either a fixed or FLAT, It, I2t and I4t function. The overcurrent tripping device also allows for relatively wide adjustment ranges for the long tine delay and short time delay protection portions of an overcurrent protection curve. In order to prevent any overlapping of the protection ranges, the long time delay portion is prevented from tripping the interrupting device prior to the short time delay portion.

Title: Paper web separator and stacking apparatus
Inventor: RING ROBERT S
IPC: B65H39/16
Filed: 1993-11-16
Abstract: ABSTRACT OF THE DISCLOSURE      A compact interstacking web deflector for causing a split paper web to overlap one side of the web over the other.  The web deflector includes a triangular support plate over which the split web flows.  The triangular leading edge of the support plate includes a pair of rods angled with respect to the paper webs.  As the paper webs flow over the respective rods, opposing twists are imparted to the side-by-side sections of the paper web that causes the web sections to merge towards the centerline of the deflector.  The twists in the web sections are removed as the sections loop under a pair of free-floating tension tubes.  In this manner, the paper webs are superimposed one over the other for subsequent processing.

Title: Corrugated pallet leg and method
Inventor: BECKWAY BRUCE C
IPC: B65D19/40
Filed: 1993-12-21
Abstract: There is disclosed an improved corrugated pallet having pallet legs attached at various points of attachment. The field of invention relates to a corrugated cardboard pallet of the type generally formed by a pair or more of pallet decks which are stacked atop one another, each of which has finger elements die cut therein radiating outwardly from a central circle and terminating on a circular score line of substantially the same diameter as the inner diameter of one of~the leg elements. The die cut lines for the fingers radiate tangentially outwardly to create a substantially spiral pattern. The leg assembly is of the type formed by an outer leg, and an inner leg, with the radiating die cut fingers nested between the annulus created between the outer and inner leg and adhesively secured to the legs. The improvement consists of die cutting a series of linearly aligned perforations along the length of each finger, such that when the adhesive is applied to the outer and inner surfaces of the fingers, the adhesive is permitted to permeate the inner confines of the corrugated material forming the fingers thereby increasing the surface area of adhesive for securing the finger elements to the respective leg elements.
