Patent CA-2004910-A1 (CA)
IPC: A47J37/00
Filed: 1989-12-07
Abstract: An automatic bread-making device comprises a housing, a cooking vessel removably arranged therein and provided at its bottom with a rotatable shaft, a kneading blade removably attached to the shaft, and a driving mechanism for rotating the blade through the shaft.  The blade has at least one crescent-shaped projection at a wall surface of a bore for attachment of the blade to the shaft, while the shaft has at least one groove extending parallel to a line that intersects the axis of the shaft to form a head with a shape similar to that of the opening formed between the inner wall of the bore and a free end of the projection. The device further includes a sequence control system for controlling the driving mechanism and heaters.  During kneading the shaft is so rotated that, when the rotation of the blade is to be reversed, the shaft is reversed and stopped just before engagement of the driving disk with a coupling member between the shaft and the driving mechanism. The result is quieter operation.

Title: Multi-layer sheet structure for the reinforcement of panels, a method for the reinforcement of panels and a reinforced panel
Inventor: HALG PAUL
IPC: B32B7/02
Filed: 1989-12-15
Abstract: Abstract The invention relates to a multi-layer sheet structure for the reinforcement of panels. The multi-layer sheet structure comprises a supporting layer which in turn comprises a curable plastic material and a reinforcing material combined with or embedded in said curable plastic material. The multi-layer sheet structure further comprises an adhesive layer applied on said supporting layer on the side facing the panel to be rein-forced. The adhesive layer comprises a curable plastic material optionally provided with fillers or other additives. In order to achieve a reinforcing and stiffening effect as high as pos-sible without deformation of said panel, the adhesive layer, after curing, has a modulus of elasticity which is higher than the modulus of elasticity of the cured plastic material of the supporting layer, and the supporting layer, after curing, has a coefficient of thermal expansion which is essentially the same as the coefficient of thermal expansion of the panel to be re-inforced.

Abstract: METHOD AND DEVICE FOR IMPROVED REACTION KINETICS        IN NUCLEIC ACID HYBRIDIZATIONS                  ABSTRACT OF THE DISCLOSURE           The present invention relates to methods and test strips for performing nucleic acid hybridizations on a porous chromatographic material having the capacity for rapid chromatographic solvent transport of non-immobilized reagents and reactive solution components by means of a selected chromatographic solvent.  The strip includes a first end or contact site, at which chromatographic solvent transport begins, a second end, at which chromatographic solvent transport ends, and at least one zone positioned between the first and second ends.  The zone is impregnated with a capture nucleotide sequence which is immobilized against solvent transport and which is capable of hybridization with a complementary nucleotide sequence or probe so as to render it immobilized in the capture zone.  The strip may further include a probe zone between the first end and the capture zone, wherein a labeled probe is impregnated such that it is mobilized by the solvent and transported to the capture zone where hybridization can occur.  Interfering sample components and unhybridized nucleic acids are cleared from the capture zone by chromatographic solvent transport to form an inherent wash.

Abstract: MEASURMENT OF PERFORMANCE OF AN  EXTENDED FINITE STATE MACHINE Abstract A method and apparatus is disclosed for determining an objective measure of performance of an extended finite state machine. Many modern complex systems, for example, computer communications protocols and computer or machine user interfaces, can be represented as extended finite state machines. A formal description. of the extended finite state machine is employed to obtain a canonical form description. The canonical form description, combined with a service description, is used to generate a list of canonical state transitions transited by the extended finite state machine to perform the service. From this list, an objective measurement of performance, e.g., the time required to perform a particular service, is obtained. This objective measurement may then be used as desired, for example, to select an optimum extended finite state machine from a plurality of extended finite state machines.

Title: Process for the extraction of flushing out of a substance from a heterogenous system, and installation for carrying out the process
Inventor: DRAGICEVIC ZORAN
IPC: B01D11/00
Filed: 1990-01-16
Abstract: Abstract The process and the continuously working installation are intended for the extraction or flushing out of a substance from a heterogenous system with a solid phase of fibrous or granular material by means of a liquid, which, in the course of the process, forms a liquid phase which is increasingly loaded with the substance to be extracted or flushed out.  The solid phase (2) is advanced in the installation with conveyor means (9, 9', 9"). The liquid phase (4, 4', 4") passes through the installation substantially in the opposite direction to the solid phase.  Elements (30, 31, 32, 30', 31', 32', 30", 31", 32") for compressing and decompressing the solid phase (2) are disposed along the path of the solid phase (2) through the installation which may consist of several treatment stages (5, 5', 5") connected in series.  Means for drawing off at least a part of the liquid phase are foreseen in each of the compression zones.  The liquid phase drawn off is fed back each time to the solid phase at a location which lies counter to the flow direction of the solid phase and closer to the feed device (1) of the latter than the corresponding drawing-off means.

Abstract: TITLE          Protective System Against Icebergs or Floating Objects INVENTORS               Geoffrey R. Mogridge Edgar R. Funke ABSTRACT OF THE DISCLOSURE     The system utilizes one or more buoyant members which are attached to a mooring line or lines anchored to the sea bed. The mooring line has a length limited to provide travel constraints on the travel path of the buoyant member, whereby upon collision of floating object with the buoyant member or mooring line, the resulting lateral displacement will effect downward travel of the buoyant member and absorb kinetic energy of a floating object approaching the offshore area to be protected. In the preferred embodiment a number of buoyant members are connected to one another to partially or completely encircle the area to be protected.

The barrier is comprised of a resilient body such as flexible foam and a heat-deformable member such as a tube which defines a pas-sageway between the ends of the resilient body when the resilient body and the member are mounted in the hollow channel.  The barrier may be coated with hot melt adhesive. The barrier is mounted in the hollow channel and the motor vehicle body is dipped in a paint bath and drained.  Paint flows in and out through the passageway in the barrier, thus coating the interior of the hollow channel.  When the motor vehicle body is passed through the bake oven,  the heat-deformable member collapses, the barrier is closed, and the hot melt adhesive bonds the barrier to the channel.
