Title: Container with tamper-evident lid removal means
Inventor: VON HOLDT JOHN W SR
IPC: B65D17/32
Filed: 1994-07-18
Abstract: A plastic container defines a sidewall closed at one end and open at the other end.  A container lip is defined at the other end which comprises a pair of spaced walls surrounding the longitudinal axis of the container,  to define a recess between the walls for receiving and locking a peripheral container lid portion on the container.  The outer of the pair of walls defines at least one pair of spaced points of tearing weakness to permit breaking of the outer wall and outward folding of that part of the outer wall positioned between the points of tearing weakness, to provide access to the peripheral lid portion for lid removal.  The container may be designed so that the lid cannot be removed without the breaking of the points of tearing weakness,  to provide tamper indication to the container and lid.

Patent CA-2129504-A1 (CA)
Title: Locking member
Inventor: KOCKEL WOLFGANG
IPC: B62D33/02
Filed: 1994-08-04
Abstract: ABSTRACT OF THE DISCLOSURE           A locking member for use in locking together adjacent side panels on a commercial vehicle has a locking lever pivotably mounted within a hollow housing such as a stanchion.  A portion of the lever extends outside of the housing.  The locking lever has a pivot axis, and first and second arms extend from respective opposite sides of the pivot axis.   The first arm of the locking lever extends partially outside of the housing, and has a locking element for engaging a complementary locking element on an adjacent side panel; the second arm of the locking lever is within the housing.  The locking member also has two complementary engagement members, one extending from the second arm and the other having a fixed position relative to the hollow housing.  When a force above a predetermined value presses on the adjacent side panel, as happens for instance when a load on the vehicle has shifted,  the two complementary engagement members move into engagement with each other to prevent pivoting of the locking lever.  At other times a person unloading the vehicle can freely pivot a locking lever of a locking member to uncouple adjacent side panels. Thus the locking member of this invention protects a person unloading a vehicle against sudden movement caused by a shifted load on the vehicle.

Patent CA-2133875-A1 (CA)
Inventor: COPPOLA ALFRED M
IPC: H04N21/472
Filed: 1994-10-07
Abstract: Previous attempts at providing audience interaction with pre-recorded audio-visual entertainment such as movies have been limited to the audience electing between a small number of pre-determined options.  The present invention provides a method of simulating complex interaction between an audience and a pre-recorded series of audio-visual events by providing, on a computer display,  a response element on which the user selects a point on a continuum at various instants during the sequence of events, and providing a finite number of stored audio-visual events which are each associated with a range of points on the continuum, so that a selection by the user of a point within a given range causes the display of the associated audio-visual event.  The correlation between the location of the point within the continuum and the particular event selected can be varied in a random way to further simulate complex interactions.

Title: Integrated process for upgrading middle distillate production
Inventor: HUNTER MICHAEL G
IPC: C10G49/22
Filed: 1994-12-21
Abstract: An integrated middle distillate upgrading process and unit are disclosed. A middle distillate side-stream of a conventional single stage hydrocracking process is circulated to a hydrotreating stage such as an aromatics saturation reactor and/or a catalytic dewaxing reactor to effect middle distillate upgrade. The upgraded product is then finished in a fractionation stage side-stripper column. The integrated hydrotreating reactor can share the duty of existing hydrocracker stage equipment and take advantage of existing process heat to eliminate the need for much of the equipment generally required by a stand-alone hydrotreating reactor of the prior art.
Patent CA-2138895-A1 (CA)
Title: Sealant with surfaces having differential adhesion
Inventor: TIEDECK MICHAEL T
IPC: B65G49/06
Filed: 1994-12-22
Abstract: A self-adherent, shock absorbing sealant strip for use between the facing mounting surfaces of two spaced elements includes an elongated body made of a resilient material.  A first sealing surface is located on a first side of the body and a second sealing surface is located on a second side of the body. Differential adhesion occurs between the first and second sealing surfaces so that the first sealing surface adheres more strongly to an associated first element than does the second sealing surface to an associated second element.  The first and second associated elements are preferably a workpiece and a carrier body, respectively.  Because the sealant adheres more strongly to the workpiece than to the carrier body, when the workpiece is removed from the carrier body, the sealant stays with the workpiece.

Patent CA-2151350-A1 (CA)
Inventor: GLODOWSKI ROBERT J
IPC: C21D9/573
Filed: 1995-06-08
Abstract: A method and apparatus are provided for producing rods   having  a  desired tensile strength from a rod manufacturing process set to an optimal operating condition.          Initially, the rod manufacturing process is set  in an optimal condition to produce rods at a maximum rate, while optimizing the mechanical properties therein.  Raw materials are melted and a "heat of steel" representing  one lot is  poured into a ladle which is sampled to determine its chemical composition.          The percentage content of each element is utilized within an empirical model modelling the rod  manufacturing process to predict the tensile strength of rods.  The empirical model is again utilized to  determine the amount  by which a control element must be varied to adjust the predicted  tensile strength to the desired tensile  strength.  The control element represents an element, such as, carbon which significantly impacts the tensile strength of the rod.  The predicted level of the control element necessary to achieve the target tensile strength is referred to as the "floating aim level" thereof.         If the floating aim level exceeds a maximum accepted level for the control element the empirical  model  is again  used  to determine the necessary level of a second control element.          Next, the heat of steel is  trimmed to provide a lot having the target tensile strength.

Abstract: An ultrapure egg oil is prepared starting from dried and powdered avian or reptilian egg yolk by means of extraction with the aid of fat solvents, followed by two-step ageing, first at ambient temperature and then at a lowered temperature, separating off and centrifuging off the less viscous phase formed and again separating off the less viscous component. This component is, if appropriate repeatedly, mixed with demineralized water and heated, and, after cooling, the less viscous phase is separated. off and again. centrifuged, the less viscous component is again separated off and held at a lower temperature, the phases are again separated, and the less viscous component which has been separated off is recentrifuged.      This again results in phase separation, the less viscous component which has been separated off being the end product which is a yellow to reddish, fluid oil which can be stored without preservatives.      The ultrapure egg oil prepared by this process can be used for the treatment of skin burns, including sunburn, and for regenerating the skin in cosmetic products.
