Patent CA-2012845-A1 (CA)
IPC: B65D85/07
Filed: 1990-03-22
Abstract: An easy open flexible bag (15) containing one or more stacks of flexible articles (20) maintained in a state of compression in a direction substantially parallel to their thickness. For products such as disposable absorbent baby diapers, catamenial pads, incontinent briefs and the like, the degree of compression within the bag may be as much as 50% or more when compared to the uncompressed thickness of the stack of articles in question. In a particularly preferred embodiment, the bag totally encloses the stack or stacks of compressed flexible articles and exhibits a substantially rectilinear shape. The bag preferably includes an integral carrying handle. The end (30,31) panels and at least one pair of either the front and back (40,41) or the top and bottom (51,50) panels of the bag are subject to tension imposed by the stack of compressed flexible articles. This leaves at least one pair of panels, preferably the top and bottom panels, in a substantially untensioned condition. One of the substantially untensioned top and bottom panels contains an easily visible, unobstructed tear initiating device (67) which comprises a portion of the easy open device for the bag. The tear initiating device can be readily activated by the end user's fingers to create an aperture traversing at least one corner of the bag. Partially pre-erected easy open flexible bags of the present invention are filled by over-compressing the flexible articles to a dimension which is smaller than the interior of the bag and thereafter allowing the articles to expand slightly once they have been inserted within the bag. Preferred apparatus for compressing the flexible articles and inserting them into partially pre-erected flexible bags of the present invention are also disclosed.

Inventor: BINDIN PETER J
IPC: H01M2/06
Filed: 1990-05-02
Abstract: ABSTRACT           The cathode region of a sodium sulphur cell has hitherto sometimes been sealed by a thin metal member welded at its outer periphery to the metal casing and at its inner periphery to the alpha alumina lid of the electrolyte.  The welding operation damages the essential protective coating of the thin metal member.  This invention discloses sealing the cathode region with a thin metal member secured to a concentric outer thicker metal member, the thin member being sealed to the lid and the thicker member being sealed to the casing.  The thickness of the outer member eliminates the need for a protective coating so that the combined seal has greater integrity than previous seals.

Filed: 1990-09-20
Abstract: WHEEL TREAD ADJUSTING DEVICE    Abstract of the Disclosure A wheel tread adjusting device has a flat plate provided with a plurality of holes.  Two of the holes align with the jack screw bores normally present in a tapered sleeve-type hub to mount the plate to the tapered sleeve.  A cut-out bore allows the plate to rest flush against the tapered sleeve without interfering with the normally present lug bolts.  Two additional bores are positioned radially outside of the tapered sleeve and hold jack screws to unwedge the tapered sleeve from the hub.  An adjustment rod is selectively engageable with either of two adjustment bores in the plate. Another portion of the rod can be threaded through a bracket mounted to the end of the axle, or through a lug bolt bore in the hub of an outer wheel, if dual wheels are present.  The structure is extremely simple, uses the normally present bores to the maximum extent, and is made predominantly of standard available parts.

Title: Fluid actuated friction damper
Inventor: PATON H NEIL
IPC: B60G17/06
Filed: 1990-11-09
Abstract: FLUID ACTUATED FRICTION DAMPER                  ABSTRACT OF THE DISCLOSURE        The fluid actuated friction damper comprises a cylinder and an expandable piston assembly made up of a postion having two spaced apart parallel end walls which form an annular chamber, and two spaced apart side walls which project toward one another and terminate in two spaced apart parallel edges.  These edges define a curved opening for the chamber which fronts upon the inside of the cylinder.  A curved friction member is located between these edges in this opening, and is pressed against the insdie of the cylinder by an underlying flexible actuator ring.   This ring has a width greater than the spacing between the side wall edges and is located inside of the side walls so that the ring simultaneously self-seals against the side walls and bulges outwardly thorugh the opening, thereby pressing the friction member against the inside of the cylinder when the chamber is pressurized. The friction member is contained in a fixed position with respect to the piston between the side wall edges, the inside of the cylinder and the flexible actuator ring. The frictional damping force obtained is controllable in relation to the direction of movement of the piston assembly within the cylinder, either by control of the surface area of the actuator ring exposed to a single fluid presure, using fluid pressures less than 35 psi.

Abstract: A time base correcting apparatus having a memory for storing a reproduced video signal reproduced by a rotary magnetic head from slant tracks of a magnetic tape which is transported at a desirable tape running speed relative to a tape running speed upon recording mode, a write in-line address counter for generating a write in-line address signal and a write line address counter for generating a write line address signal for the memory, a write clock signal generating circuit for generating a write in-line address increment clock signal and a write line address increment clock signal each being synchronized with a horizontal synchronizing signal separated from the reproduced video signal, and for supplying the same to the write in-line address counter and the write line address counter, a read in-line address counter for generating a read in-line address signal and a read line address counter for generating a read line address signal for the memory, and a read clock signal generating circuit for generating a read in-line address increment clock signal and a read line address increment clock signal each being synchronized with the reference horizontal synchronizing signal, and for supplying the same to the read in-line address counter and to the read line address counter, in which when the detecting circuit detects that the single cycle of one periodical signal of the periodical signals which are respectively synchronized with the reproduced horizontal synchronizing signal and the reference horizontal synchronizing signal is involved in the single cycle of the other periodical signal, the line address increment clock signal which relates to the horizontal synchronizing signal synchronized with the other periodical signal is inhibited from being supplied to the line address counter so that the reproduced video signal is removed or interpolated in the unit of lines at an equal position of a reproduced picture.          Thus, a reproduced picture having no distortion can be obtained regardless of tape running speed and tape running direction in the reproduction mode.

Filed: 1990-12-04
Abstract: COMPARTMENTAL BODY FLUID COLLECTION TUBE              ABSTRACT OF THE DISCLOSURE       A compartmented body fluid specimen collection tube is provided which allows the user to select a size  compartment  depending  upon  the  quantity  of specimen required.  Thus, the tube of the invention may be of the standard size which is much easier for the user to handle than very small tubes when taking  a  blood  sample,   but  a  selected  size compartment is available.   The manufacturer of the tube itself may use a single mold for making tubes accommodating    differing     required   specimen quantities,  and,  thereafter the vendor may select either size compartment for imparting a vacuum and the  other   processing   required   into   a   final product.  The invention allows the use of a single standard   size   laboratory   equipment  array  for processing   collected   specimens    of    varying quantities,  as well as a single standard stopper. Finally,  reduced  vacuum  application  or  "partial draw"  tubes  are  avoided,  thus  eliminating  the problem  of  unpredictable  specimen  draw  response because   of   varying   atmospheric   pressures   at different locations of use.
