Abstract: INTRAMEDULLARY CANAL SEAL FOR CEMENT PRESSURIZATION          Abstract A novel cannula is disclosed for use in the application of bone cement to the prepared intra-medullary canal of a bone prior to the cementation of a surgical implant therein.  The novel cannula comprises a hollow tube adapted to slidingly receive the nozzle of a bone cement extruder, an inflatable cuff surrounding the tube, and means to inflate the cuff.  In operation, the inflated cuff forms a seal against the wall of the intramedullary canal, thereby preventing escape of cement through the open end of the prepared canal and insuring that the applied cement is properly pressurized within the canal.  As a result, a highly secure cementation of the surgical implant within the intramedullary canal is achieved.

Abstract: CENTRIFUGAL HEATING UNIT ABSTRACT OF THE DISCLOSURE A centrifugal heating unit includes a circular plate unit mounted on a rotatable shaft in a housing.  A motor rotates the shaft and spins the plate unit within the housing.  The plate unit is immersed in multi-viscosity synthetic oil.  The plate unit includes first and second circular disks of equal diameter which are attached to and separated by a spacer disk of smaller diameter.  A peripheral buffeting area is formed between the disks outside the perimeter of the separator plate.  Each disk of the plate unit is provided with slots equally spaced around the periphery, extending from the separator plate out to near the perimeter of the disk.  Each slot is aligned at a 45° angle to a radius of its disk.  As the plate unit rotates, oil moving radially outward due to centrifugal force is drawn through the slots into the buffeting area between the disks where it is buffeted, which generates heat.  The hot oil heats the housing, from which heat is transferred to warm the ambient air.

Abstract: ABSTRACT Hologram apparatus for detecting flaws has a photo-graphic station for supporting a photosensitive medium. The photographic station together with the photosensitive medium forms a developing chamber with a transparent face having a depth in the range of from about .005" to about .125, preferably from about .005" to about .080". The developing chamber has a periphery with a contour which always changes at an angle greater than about 115° and is preferably circular. Associated hydraulic equipment supplies and removes fluid from the developing chamber. A laser supplies coherent light for the article to be tested for reflection to the photographic station. A reference beam is directed to the photographic station. For use in inspecting pipe in the field, the apparatus advantageously has a housing and a pair of saddles each having different diameter pipe re-ceiving portions and a strap securing system. The photographic station can develop the photosensitive medium in situ and may be used in any spatial orientation. The invention also comprises the photographic station per se without the laser.

Abstract: ABSTRACT     Conventional heat stretching and/or setting conditions for fabrics made of heat sensitive thermoplastic yarns such as polyester, and even special techniques advanced in prior patents, have been found in adequate to produce coated abrasives with sufficient elon-gation resistance for some very heavy duty service.  A superior alternative is provided by encasing the yarns in the backing in a thermosetting adhesive and then curing it while mechanically restraining the yarns from shrinking, as they would under the tem-perature conditions employed for cure if no restraint were used. The method is also applicable to other types of yarn reinforced web materials for which a combination of elongation resistance and flex-ibility is needed.

Abstract: PRODUCTION OF DIELECTRIC INSULATION  LAYERS UPON ELECTRICAL CONDUCTORS                 Abstract of the Disclosure Monitoring of the quantity of magnetically perme-able particles in a dry dielectric carrier layer surrounding a conductor by passing the conductor with its surrounding layer through a magnetic field created by a magnet to cause magnetic attraction between the particles and the magnet. The degree of this attraction is dependent partly upon the quantity of particles lying in the field and the degree of movement towards each other of the conductor and magnet is monitored while resistance to this movement is provided, to give an indication of the particle quantity.  A method of controlling the quantity of particles on the conductor is also described which uses the monitored movement to produce signals by which the input of particles or carrier into a fluid mixture is adjusted.                             - i -

Abstract: REMOTELY-CONTROLLED TOY VEHICLE                   Inventor:  Christopher Charles Wiggs and Christopher Joseph Crabtree, both British subjects and residents of London, England.                      ABSTRACT OF DISCLOSURE          A remotely-controlled toy vehicle having a steering mechanism and driven by a dc motor selectively connected to a battery by a multi-position switch in a polarity which causes forward or reverse movement.  Remote control is effected by a handset having first and second master diaphragm chambers linked through a flexible pneumatic line to first and second slave diaphragm chambers in the vehicle, one slave being operatively coupled to the steering mechanism and the other to the motor control switch.  The handset is provided with a torsion bar having a handle, the bar being both swingable from side to side and also being rotatable.  The bar is so coupled to the dia-phragms of the master chambers whereby when the player swings the bar toward the left or right, this movement is pneumatically transmitted to the steering mechanism of the vehicle to cause the vehicle to turn toward the left or right.  When the player rotates the bar clockwise or counterclockwise, this movement is pneumatically transmitted to the switch to cause the vehicle to travel in the forward or reverse direction.

Abstract: ABSTRACT    The present invention relates to a two step process for decarburization of a shallow melt.  First, the carbon content of the melt is reduced to an intermediate value in the range of about 0.3 to 0.1 wt.% carbon by concurrently blowing an oxygen enriched gas onto the surface of the melt at a subsonic velocity and injecting an inert gas below the melt surface to stir the melt.  Second, the carbon content of the melt is further reduced to a final value of above 0.001 wt.% carbon by injecting a mixture of oxygen enriched gas and inert gas below the surface of the melt for both decarburizing and stirring the melt.

Abstract: Contour Forming Conical Shapes Abstract A truncated conical segment is made by the steps of contour rolling two pieces of metal, then longitudinally welding them, followed by contour rolling the weldment to preferentially reduce one of the pieces of the weldment more than the other.  This provides a skewed trapezoid shape which is then 3-roll formed into a ring having a conical shape.  The angle of the cone is a function of the preferential reduction in the second contour rolling step.
