Patent CA-2085985-A1 (CA)
Inventor: BESSE MICHAEL E
IPC: C11D17/00
Filed: 1991-06-28
Abstract: The stability of polyvinyl films used to contain detersive systems may be enhanced by the use of a barrier coating composition to separate the film degrading components, i.e., acids, bases, and halogens, from these films. The barrier coatings may either encapsulate the individual film degrading components, or they may coat the entire detersive system.

Title: Air shroud device for a blown film extrusion line
Inventor: CREE ROBERT E
IPC: B29C48/10
Filed: 1993-02-04
Abstract: An air shroud device for a conventional blown film extrusion line. The line has air cooling ring(s) to direct primary cooling air along the bubble to cool the film to the frost line. The air shroud device comprises an annular air shroud plenum having an annular air outlet at a level below the frost line. The shroud device is coaxial, of relatively large size so that its outlet mechanism is spaced substantially radially from the bubble and from the outlets of the air cooling ring(s).      The air shroud plenum receives air from a source uninfluenced by variable conditions, and provides a diffused source of the air about the bubble to serve as pseudo-ambient air. Secondary air flow induced by primary flow of cooling air from the air cooling ring(s) comprises air drawn from the spaced-apart air shroud device and not from ambient air.

Title: Surgical orthopaedic cast, method and the apparatus designed to maintain a hygiene whithin and under the surgical cast, especially in a serious cases of a bone fracture
Inventor: PROBA JERZY
IPC: A61M35/00
Filed: 1993-08-06
Abstract: Abstract This invention solves the problem of moisturizing of materials underlining the surgical orthopaedic cast.  The invention allows to raise the standard of hygiene, and improves skin's respiration by providing ventilation into a space under the cast. Process of ventilation occurs in a manner of drawing away the transpiration products and forcing a flow of air and medically useful substances into a space within the cast.  Also it enables a continuous analysis of microbiological processes, that, take place under the cast without breaking or taking it off.  This is the way that this apparatus works; within a space of the surgical cast, between the surface of body, and the outer surface of a surgical cast, a layer of drains that enforces the flow of gases within the said space, is placed.  Drains, are joined by a pipe, to an apparatus outside the surgical cast, such as medicine dispenser microbiological filter with chemical - microbiological analyzer, with the heat exchanger containing thermostat, ozone generator with an oxygen access, air filter, and a draw - lift pump with reversible actions.  Elements of the apparatus located outside the surgical cast can be hooked up separately and in different and independent order, also they can be turn off depending on the demanded treatments.  Activating and deactivating of the elements depends on actions such as drying of the surgical cast, or simultaneous drying and disinfecting of the surgical cast as well as, simultaneous drying and diagnosing of the microbiological processes are carried on.  This apparatus is very applicable in long term healing processes where the surgical cast has to be kept for extended period of time.                               15 claims 10 drawing figures

Title: Valve gated injection molding apparatus with a spring in the piston
Inventor: TENG ALEX C
IPC: B29C45/28
Filed: 1993-12-13
Abstract: Valve gated injection molding apparatus with a spring mounted on a central pin adjacent the head of a valve member in a spring chamber in each of the pistons.      The spring is compressed between the base of the pin and the cap of the piston to preload it. When the valve member and piston are driven forwardly to the closed position, the head of the valve member retracts somewhat into the spring chamber against the force applied forwardly against the head of the valve member by the spring. This cushions the impact of the front end of the valve member in the gate and provides for tight seating of the front end of the valve member in the gate without requiring all of the components to be made to precise tolerances with exact allowance for thermal expansion. The spring is a number of selected disc springs stacked in sets facing in opposite directions, from which the force applied to the head of the valve member is predetermined.

Title: Device and method for measuring the jitter of a recovered clock signal
Inventor: WONG HEE
IPC: H04L1/20
Filed: 1993-12-14
Abstract: ABSTRACT      A jitter extraction circuit, which includes a cyclic phase differentiator, a control loop, and a jitter integrator, measures the jitter of a recovered clock signal formed from an incoming data bit stream. The phase differentiator differentiates a phase data word, which includes both a jitter component and a delta frequency component, to produce a differentiated phase data word.  The control loop estimates and removes the delta frequency component to produce a filtered data word which primarily represents the jitter component.  The jitter integrator recovers the original jitter component by integrating the filtered data word to produce a jitter data word.  The jitter of the recovered clock signal is determined by the statistics of the jitter data words.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for suspending and connecting a pair of tubular members, particularly a pair of radiant heater tubes, wherein each tubular member has an expanded end and a straight end so that successive tubular members are connected by slip joints.   The suspending and connecting apparatus of the preferred embodiment includes a pair of brackets fixedly secured to the body of one tubular member generally adjacent to the straight end thereof, and a pair of semi-circular clamping members forming a ring about the adjoining tubular member and engaging the expanded end thereof.          Holes formed in the clamping members and brackets are alignable so that a pair of screws may be inserted therein to operatively engage a pair of nuts retained by the brackets.   The brackets include holes for attachment to conventional suspension systems, so that one bracket for each tubular member may be employed to suspend the assembly from a ceiling or other overhead support structure.  The compressive forces created by the clamping members and brackets effectively prevents relative longitudinal and rotational movement between the tubular members.
