Patent CA-1284629-C (CA)
Title: Child resistant package
Inventor: COOKE CARL W
IPC: B65D41/06
Filed: 1986-12-31
Granted: 1991-06-04
Abstract: CHILD RESISTANT PACKAGE     Abstract An improved child resistant package comprising a con-tainer and closure and resilient means for normally urging the closure axially away from the container when the container is sealed by the closure.   Cooperating sets of locking elements rim the container adjacent its mough and are disposed about the inner surface of the depending skirt portion of the container for lock-ing and maintaining the closure in a sealed position over the mouth of the container.  One set of the locking elements comprise pairs of spaced apart projections which define a through-running channel therebetween.   The other set of locking elements comprise corres-ponding latch members, each of which define a stop element which is received in through-running channels and a retaining portion which acts against one of the paired projections to retain the closure from axial movement in opposition to the urging of the resilient member.   In the event of the shearing of portions of the projections, the locking feature of the closure is retained by virtue of the through-running channel which permit the latch member to be positioned toward the container mouth with the sur-face of the stop element in contiguity with undamaged portions of the projections.

Title: Self-regulating deicer valve
Inventor: PHILLIPS RONALD W II
IPC: F16K17/30
Filed: 1987-02-18
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE A self-regulating vacuum control valve with a needle valve operating in a narrow central bore that regulates the flow of pressurized air from a pressure source into such narrow central bore for passage and discharge from an enlarged bore.  A vacuum is pulled in passageways in such enlarged bore which exert a vacuum pull on a control chamber and on one end of a disphragm means.  The diaphragm means is connected to the needle valve and has its one end subjected to atmospheric pressure.  Such diaphragm and needle valve are spring biased to increase the air flow past such needle valve in opposition to the vacuum pull on such diaphragm.  Such spring bias is adjustable to provide a predetermind vacuum pull on the control chamber that can be connected to a deicer pad for maintaining a predetermined vacuum pull thereon.

Abstract: ABSTRACT      Apparatus  is  described  which  provides  enhanced movements of a person's truncal spinal muscles and joints and which comprises a first means for supporting a person in position where there is minimal axial gravity loading of the spine and second means to permit relative motion between the upper (thoracic) and lower (pelvic) portions of the person's trunk while the person remains in the gravity unloaded position.  The device contains a fixed portion and a pivoting or swiveling portion.   In the preferred  embodiment  the  user  assumes  an  all  fours position and by kneeling or leaning  on the  swiveling portion engages in a swiveling motion of the body which causes the upper and lower portions of the trunk to move relative to each other.  Normal motion is in the frontal and  traverse  planes  of  the  body.    Movement  in  the transverse plane can be enhanced by incorporating a sloped structure  for the swiveling portion of the device to follow.   Simultaneous movement in the sagittal plane can also be obtained by having the user flex or extend his body during the exercise.  The two supports for the hands and knees can be mounted on the same base, mounted in a telescoping  or  adjustable  fashion  or  positioned  in separate but adjacent locations.  Extra supports can be used if a person is unable to support one or another portion of his body on his own.  The swiveling portion of the unit can be moved either by the person's own exertions or his exertions can be separately assisted by a motor drive or other means.

Abstract: Abstract of the Disclosure A vehicle-servicing trailer is attachable to a pulling vehicle for transportation to the intended ser-vicing site, the trailer having a hydraulically controlled lift apparatus, ramps on opposite sides of the trailer for advancement of a vehicle to be serviced onto the trailer, and outriggers are stationed at the four corners of the trailer to cooperate in supporting a vehicle on the trailer.  When the vehicle is loaded on the trailer via the ramps, the lift is activated to raise the track members and vehicle to be serviced so that the underside of the vehicle is accessible, and outboard extensions on the track members enable a service man or operator to gain access to the engine compartment and interior of the vehicle.  A movable dolly is positioned centrally of the trailer to permit the operator to slide beneath the vehicle and to perform necessary servicing operations, such as, oil changes and lubrication jobs.  An oil drain tank is incorporated into the trailer to receive waste oil and the necessary oil and grease lines extend from suitable sources of supply at the rear of the pulling vehicle to facilitate servicing.

Title: Production of immunoproximity catalysts
Inventor: KIM PETER S
IPC: C12N9/00
Filed: 1988-12-22
Granted: 1999-05-11
Abstract: The  invention  relates  to  novel  immunoproximity catalysts. The catalysts are derived from antibody molecules.          The  process  includes  selecting  a  hapten  based  on  its relationship to the structure of a transition state complex of the selected reaction so that the hapten, upon attachment to a carrier protein and injection into an animal, elicits an immune response in which the desired antibody is produced.   This antibody is modified by the specific, covalent attachment of the catalytic group involved in the selected reaction, yielding an immunoproximity catalyst which is a substrate-specific, antibody catalyst.

Abstract: A   swab   transport   apparatus   for   storing   and transporting to a laboratory a swab containing a sample or specimen   such   as   a  micro  organism   sample.    The uncontaminated swab is pre-packaged within a sterile swab storage  chamber  of  the  apparatus  from  which  it  can conveniently be removed  for  taking a  sample.   Disposed proximate the swab storage chamber  and in communication therewith, is a squeeze bulb to which a suitable transport medium can be added either at time of manufacture of the device, or shortly prior to use.  Following addition of the transport medium the squeeze bulb and the return of the contaminated swab to the apparatus,  the squeeze bulb is squeezed to cause the transport medium to flow, preferably via a circuitous path, into the swab storage chamber.  The apparatus can  then be  forwarded to  the  laboratory  for testing  with  the   swab  safely  immersed  within  the appropriate transport medium.  In an alternate form of the apparatus, a second squeeze bulb is provided.  This second squeeze bulb  is  in communication with the  swab  storage chamber and enables withdrawal therefrom of a sample of the transport medium which surrounds  the  contaminated  swab. Where appropriate, the second squeeze bulb can be severed from the apparatus  and forwarded to the  laboratory for preliminary testing.

Abstract: ABSTRACT      A Process For The Production of Microcapsules In a process for the production of microcapsules by coacervation of gelatin, carboxymethyl cellulose (CMC) and a second anionic polymer such as a polyvinylmethylether/-maleic anhydride copolymer or an ethylene/maleic anhydride/copolymer, the weight ratio of gelatin:CMC is chosen to be in the range 1:0.14 to 1:0.05, and the CMC used is chosen to have a viscosity in the range of from 50 to 140 mPas (cps), when measured in 6.0% by weight aqueous solution at 20°C using a Brookfield RVT viscometer, Spindle No. 1, 10 r.p.m.   The use of the specified weight ratio and CMC type permits significant increases in the solids content at which encapsulation can be carried out without increasing process viscosities to an unacceptable extent and/or giving rise to poor quality microcapsules. The process is particularly suitable for producing microcapsules for use in pressure-sensitive copying paper.
