Title: Bail for container and attachment means therefor
Inventor: LUBURIC FRANO
IPC: B65D25/32
Filed: 1994-01-21
Abstract: ABSTRACT OF THE INVENTION         A container bail incorporates securement means cooperative with retaining means on a container, said securement means having a head receivable in a receptor opening in the retaining means which is of totally different size and configuration from the receptor opening in the securement means which creates an interference fit materially reducing the likelihood of inadvertent dislodgement of the securement means from the retaining means.  The bail also incorporates flexibility at critical points which augments the tendency of the retaining means to remain operatively associated with the securement means.

Title: Triangular Deposition Chamber for a Vapor Deposition System
Inventor: GOELA JITENDRA S
IPC: C30B29/36
Filed: 1994-03-28
Abstract: A process and apparatus for the manufacture of chemical vapor deposited silicon carbide which comprises conveying the reaction gases to a triangular chemical vapor deposition cell where material is deposited by chemical vapor deposition.  The triangular cell provides a large surface area for deposition while occupying a minimum amount of the furnace floor surface area.

Patent CA-2121056-A1 (CA)
Inventor: FLYNN STEPHEN
IPC: G09B23/28
Filed: 1994-04-12
Abstract: A CPR mannequin for practising cardiopulmonary resuscitation of a human has a simulated human head and neck portion with an air passage extending from a mouth opening to neck opening in an end of the neck remote from the head, and an inflatable simulated human chest portion secured to the neck and having a flexible wall member simulating a chest.which, rises and falls with inflation and deflation of the chest portion. The inflatable chest portion has an air capacity representative of a lung capacity of a human adult, and a further air passage connecting the air passage in the neck to the inflatable chest portion. A flow control valve in the further air passage operates to permit air blown through the mouth opening to pass through the air passage in the head and neck portion and through the further air passage into the chest portion to inflate the chest portion and cause the flexible chest wall member to rise, and operates to cause air from the chest portion when deflating to be released to the atmosphere without passing back into the head and neck portion. The inflatable chest portion may have a releasable retainer which operates before release to reduce the air capacity of the chest portion to a volume representative of the lung capacity of a human child, the releasable retainer being released by air pressure caused by continued blowing of air into the mouth opening when the chest portion has been inflated to an extent representative of the lung capacity of a human child. An angle responsive air flow prevention device may be located between the mouth opening and the inflatable chest portion to prevent flow of air from the mouth opening to the inflatable chest portion when the head and neck portion is not sufficiently rearwardly inclined relative to the chest portion as is required in real life cardiopulmonary resuscitation and to permit air flow when the head. and neck portion is rearwardly inclined as required. The mannequin may also include a resiliently compressible simulated human heart portion located beneath the flexible chest wall member.
Patent CA-2121828-A1 (CA)
Inventor: RICHMOND JAMES W
IPC: F16K31/40
Filed: 1994-04-21
Abstract: A household appliance, solenoid controlled, pilot actuated inlet water valve hasa diaphragm insert with a bleed valve that substantially closes when a main valve is open to reduce water and contaminate flow through the bleed passage. The pilot valve outlet extension has openings to reduce vacuum drawn from the outlet into an actuation chamber thereby further reducing water flow through the bleed passage. The bleedpassage is internally and externally configured to reduce contamination impairment. An anti-hammer rib or lip is placed on the pilot valve outlet extension upstream of a guide tip which provides less close-fitting surface that may be impaired by contaminates while still dampening valve closing to reduce valve noise and pipe hammer.

Title: Method and product for diagnosis of collagen tissue destructive diseases such as periodontitis
Inventor: SODEK JAROSLAV
IPC: C12Q1/37
Filed: 1993-09-02
Abstract: A method and product for the diagnosis of collagen tissue destructive diseases, such as periodontitis. A method includes collecting a sample of extracellular fluid from a potentially diseased site of a mammal. It is ascertained whether an amount of collagen-destructive enzyme in an active form is present in the sample in excess of a pre-determined threshold amount, such pressence indicating the likely diseased condition of the site. The enzyme may be active gelatinase or active collagenase. Examples involving periodontitis and the use of a mouth rinse for collecting the sample are given. A capsule, being of collagen (or gelatin) is described. The capsule contains a colored substance and a wall of such thickness that when the capsule is exposed to a sample containing active collagenase (or active gelatinase) exceeding the threshold amount, degradation of the wall occurs to relase the dye from the capsule to indicate the presence of the disease at the site from which the sample was collected.
