Patent CA-2236005-A1 (CA)
Inventor: GORGES DITMAR L
IPC: E03C1/28
Filed: 1996-10-25
Abstract: Improvements in retention of the oily liquid sealant (20) in an oil-sealed odor trap (10B), for drain applications such as a waterless urinal or anti-evaporation floor drain, are accomplished by making the liquid flow path (22A, 22B) substantially horizontal as a departure from conventional practice of substantially vertical flow. The trap (10B) is structured to realize the substantially horizontal liquid flow path (22A, 22B) and to locate the flow path immediately beneath the sealant layer (20) or beneath a baffle portion (16B) that is sloped such that stray sealant droplets migrating upwardly to the upper surface of the flow path due to their buoyancy will be recaptured and returned to the main sealant layer (20). To accomplish substantially horizontal flow (22A, 22B), the entry compartment can be made to have entry (16D) and exit openings substantially offset from each other. The baffle between the entry compartment and the discharge compartment, which has traditionally been made entirely vertical, is made to have a non-vertical portion (16B) that is preferably sloped for sealant recovery. A sealant sheltering region can be provided in the vicinity of the entry region to prevent catastrophic loss of sealant in the event of high pressure water flushing.
Patent CA-2236211-A1 (CA)
Inventor: ABEL ALBERT E
IPC: C09K5/04
Filed: 1996-10-28
Abstract: Refrigerants, such as Freon 12 and other potential ozone depleting substances will be in short supply as their production is phased out, and until existing refrigeration equipment is retrofitted to receive more environmentally friendly refrigerants. Existing supplies of such refrigerants when contaminated with other refrigerants especially hydrofluoroalkanes like Freon 22 can form azeotropes, which are not readily separated by conventional distillation methods, are selectively decomposed in-situ by reacting with aqueous solutions of metal hydroxides or other bases. The remaining nonreacted refrigerant-containing composition is readily recycled by separation and recovery methods from the reaction mixture to provide a reusable refrigerant composition virtually free of contaminating refrigerant.

Title: Heat exchanger adapted for the production of carbon black
Inventor: BERGLUND GOERAN
IPC: F28F9/00
Filed: 1996-11-29
Abstract: A tube heat exchanger intended to be used for the production of carbon black, comprises a cylindrical chamber (16) which is enclosed by a cylindrically shaped outer shell wall (14') and two end walls (17, 18), and a plurality of tubes (13') which extend through the entire cylindrically shaped chamber (16), from one end wall to the other. To the heat exchanger are provided an inlet (1') and an outlet (25) for gas intended to flow on the outside of the tubes (13'). Moreover, the heat exchanger comprises a further shell wall (23), which is cylindrical and placed inside and concentrically with the outer shell wall (14'), so that a cylindrically shaped gap space (29), which is open at both ends, is formed between the two shell walls. The gas entering through the inlet (1') passes this gap space (29) before it comes into contact with the tubes (13'). The advantage of this is that the outer shell wall is cooled and that the amount of carbon precipitations within the tubes diminishes.

Title: Composition for sealing wounds
Inventor: KOSOW DAVID P
IPC: A61L24/10
Filed: 1997-02-06
Abstract: A hemostatic bandage contains powdered fibrinogen and thrombin adhered to a fibrous matrix with a viscous, nonaqueous adhesive such as a viscous polysaccharide, glycol, or petroleum jelly. The nonaqueous adhesive does not allow a hydrolytic reaction to occur between the fibrinogen and thrombin until the bandage is moistened by a body fluid, such as blood. Hence the bandage can be prepared and stored for prolonged periods while retaining hemostatic activity.

Patent CA-2256427-A1 (CA)
Inventor: SIESS THORSTEN
IPC: A61M60/88
Filed: 1998-03-31
Abstract: The invention relates to a blood pump which has a drive part (11) and a pump part (12), said pump part being extended by means of a flexible hose (13). Pressure sensors (60, 61) detect the pressure difference between the inlet end and the outlet end of the pump. The volume flow can then be determined from the pressure difference in conjunction with the rotational speed. The pressure difference can also be used to determine the correct position of the pump in the heart. Alternatively, the current consumed by the motor (21) is measured and the volume flow of the pump is calculated from this current consumption measurement, taking into account the known rotational speed. The signal of the pressure measurement device or the motor current can be used to determine the correct position of the pump in the heart.

Title: Method and apparatus for venting a diecasting mould of a diecasting machine
Inventor: GUTH HEINRICH
IPC: B22D17/14
Filed: 1999-02-17
Abstract: In order to vent a diecasting mould of a diecasting machine, it is proposed that the mould cavity and/or the pressure chamber are vented during the filling operation by a second venting valve, additionally to a first venting valve. The first venting valve is located in a venting channel portion that communicates with a venting channel leading out of the mould cavity. For operating the first venting valve, an impact transmitter is provided that is operationally connected to the first venting valve and that is exposed to and moved by the casting material advancing from the mould cavity to the venting channel. The second venting valve is operated by separate independent means and is closed before the mould cavity is completely filled. As a criterion for closing the second venting valve, the length of the path can be used along which the casting piston runs during the filling operation.

Title: Adjustable mobile machine base systems and methods
Inventor: BALOLIA SHIRAZ
IPC: B62B5/04
Filed: 1999-03-26
Abstract: An adjustable mobile base that accommodates machines of different effective footprints and allows them to be selectively moved from place-to-place or fixed at a given location. The mobile base assembly comprises a frame assembly comprised of corner members and side members. The side members are telescopically received within the corner members such that a width dimension and depth dimension of the base assembly can be changed to accommodate machines having different effective footprint. A lock system may be provided which employs one or more lock assemblies. Each lock assembly comprises a lock member that is slidably received within a lock housing and a drive member which is threadably received within the lock housing. Rotating the drive member in one direction elevates one or more wheels of the base assembly and thus frictionally engages the floor surface and prevents movement of the machine on the base assembly. Turning the drive member in the opposite direction allows the stop member to be retracted up into the housing assembly. In this unlocked position, the weight of the machine is borne by wheels that allow the machine to be rolled from one location to another.
