Patent CA-1329877-C (CA)
Inventor: TOEWS CYRIL
IPC: D04D7/06
Filed: 1988-06-30
Granted: 1994-05-31
Abstract: ABSTRACT:           Decorative pompoms are manufactured by drawing rolls of tubular plastic film over individual separators to open the tubes, and severing the tubes longitudinally into strips.  The strips are condensed to a rod that is heat sealed in a compressed state at intervals along the rod.   The resultant intermediate product may be severed between the sites of heat sealing to form individual, centrally sealed segments.   The segments, when expanded at the ends, form pompoms.  A fastener such as a string may be incorporated into the rod.

Abstract: ABSTRACT OF THE INVENTION            ACCELERATOR FOR FISHING JAR WITH HYDROSTATIC ASSIST      An accelerator for a fishing jar is disclosed.  The accelerator includes front, compression, rear, and air chambers.  These chambers insure that the pressure of the fluid in the compression chamber is substantially independent of the temperature of the fluid and the hydrostatic pressure of the well.  These chambers also insure that the high pressure seals of the compression chamber are lubricated on each side of each seal.  The accelerator also insures that a threshold upward force which is proportional to the hydrostatic pressure must be applied to the drill string before the fluid in the compression chamber begins to be compressed, thereby providing an accelerator that has a higher maximum load in deep wells.

Title: Propeller and coupling member
Inventor: GEARY EDWIN S

Filed: 1988-10-31
Granted: 1993-01-12
Abstract: Abstract of the Disclosure Disclosed is a marine propeller for inboard, outboard, or inboard/outboard motors.  The propeller is made from a non-metallic composite material that will not deform or deflect even at very high horsepower or RPMs.  At the same time, the propeller is substantially less expensive than traditional metallic propellers.  An especially unique feature of the propeller is that, unlike metallic propellers, it will  shatter when it strikes a solid object in the water, thereby avoiding the engine and drive line damage that occurs when rigid metallic propellers strike a soiled object.  Also disclosed is a coupling member that permits the propeller to be adapted for use with most inboard/outboard motor configurations.

Title: Fault detection
Inventor: LOPETRONE JUAN P
IPC: G01R31/02
Filed: 1988-12-07
Granted: 1991-10-22
Abstract: ABSTRACT           Apparatus for the detection of leakage current in a system includes a power supply (800) and conductors from the supply for supplying power to a load (813) connected to the system. There is an interrupter (806) connected in the system and to a ground point (807) such that a ground leakage current in the system has a closed circuit.   Activation of the interrupter every 12 seconds effectively generates a pulse interrupted ground fault signal.  Such signal is detected by a magnetic sensor (25) located relative to a multi-feeder system with high capacitive reactance (810).  The sensor is immune to random electromagnetic and electrostatic conditions in the distribution system.  The sensor (25) is synchronized to operate with the interrupter (806) so that sensing is effected at a steady level of a square wave interrupted pulse.

Abstract: ABSTRACT A medical irrigation device for alternately introducing fluid into and withdrawing fluid from a body cavity through a conduit includes a container defining a fluid-receiving volume and having an open neck, a filter disposed within the container volume for separation of tissue particles above a predetermined size from fluid introduced from the container into the body, and a cap for interconnecting the open neck and conduit.  In an improved irrigation device, the filter consists of an elongated filter element disposed adjacent the open neck and extending within the volume of the container, the filter element being disposed about an axis and defining a filter opening axially aligned with and spaced from the open neck.  Application of compressional forces upon the container in directions transverse to the axis of the filter element urges fluid toward and through the filter element substantially free of tissue particles in excess of a predetermined size, to pass through the open neck into the conduit toward the body cavity.  Upon release of compressional forces, the container expands to withdraw unfiltered tissue-particle-bearing fluid into the container via the open neck and generally axially within the filter element through the filter opening.

Abstract: An  improved  process  for  producing  an  anisotropic  pitch product  suitable  for  carbon  fiber  manufacture.   A  carbonaceous feedstock substantially free of mesophase pitch is heated for a period of  time  at  an elevated  temperature  while  passing  an  oxidatively reactive sparging gas such as a mixture of oxygen and nitrogen through the feedstock.  The oxidatively treated feedstock is then subjected to a heat soak, for a longer period of time in the absence of a sparging gas.  Thereafter the heat soaked feedstock is heated at an elevated temperature in the presence of a non-oxidative sparging gas for a time period equal to or less than the heat soak to produce an anisotropic pitch having from 50 to 100% by volume mesophase which is suitable for producing good quality carbon fibers.

Abstract: Abstract Hollow, polymeric, acrylate, infusible, inherently tacky, solvent-insoluble, solvent-dispersible, elastomeric pressure-sensitive adhesive microspheres having an average diameter of at least about 1 micrometer. Preferred microspheres are those wherein a majority of the hollow microspheres contain at least one of interior void having a diameter of at least 10% of the diameter of the microsphere.           These hollow microspheres are useful as repositionable pressure-sensitive adhesives.   The invention also provides pressure-sensitive adhesives consisting essentially of such hollow microspheres.   Aqueous suspensions of these microspheres, processes for their preparation, spray repositionable pressure-sensitive adhesive compositions, and microsphere-coated sheet materials are also provided.   Surprisingly, hollow microspheres of the invention show reduced or even eliminated adhesive transfer, in comparison with prior art repositionable pressure-sensitive adhesives which are based on solid microspheres.

Abstract: The impulse welding device includes a transistor circuit which is operated by an impulse generator. The power transistors of the transistor circuit are operated alternately in the blocked condition and in the conducting condition. The transistor circuit is connected to a direct current power source in series with the arc which is created between the welding electrode and the work piece to be welded. The transistor circuit is shunted by an ohmic resistor which allows a spacing current to flow through the ignited arc during the impulse pauses. Since the power transistors are substantially completely blocked during the impulse pauses, the power loss will be decreased.
