  • Fire resistant fitting
    Patent number: 4272643
    Abstract: A fire resistant fitting including a pair of plates having a fire rated expandable material therebetween and a pair of conduits extending from each plate with one conduit of each pair in alignment with a respective conduit of the other pair and a respective passage in the expandable material to extend separate power and communication connections through a floor. Threaded members extend from one plate through the other plate for squeezing the expandable material against the sides of the floor opening in which the fitting is located and stops on the threaded members prevent the application of excessive force to the material.

  • Multiplex time division switching network unit of the time-time type
    Patent number: 4272844
    Abstract: Multiplex time division switching network unit comprising a plurality of P groups of N incoming and outgoing multiplex highways and P incoming and outgoing supermultiplex highways each formed of N multiplex highways and having 2aN time slots where a is the number of time slots in a multiplex highway. The supermultiplex highways are multiplexed two by two and with themselves to form double supermultiplex highways each having 2aN time slots. It results that there exists a double supermultiplex highway simultaneously containing any time slot assigned to a calling party and any time slot assigned to a called party whatever be these time slots. The buffer stores of the switching network unit can thus be rendered bidirectional and their number is P(P+1)/2 instead of P.sup.2 in the prior art.

  • Method of determining change in subsurface structure due to application of fluid pressure to the earth
    Patent number: 4271696
    Abstract: This invention relates to a method of determination of the change in subsurface structure of the earth resulting from the application of fluid pressure at a selected point, at a selected depth, in the earth, by measuring at least one physical parameter of the contour of the subsurface of the earth above the point of application of fluid pressure. The method involves positioning a plurality of tiltmeters on the earth above the point of application of fluid pressure arranged in a known array, and measuring the change in angle of tilt of the earth's surface at the point of placement of each sensor while varying the pressure and flow rate of fluid into the earth at the selected point.

  • Manufacture of cheeses
    Patent number: 4271201
    Abstract: Cheese is produced by a process wherein milk is subjected to partial ultrafiltration, heat denatured serum proteins are added to the milk before or after ultrafiltration, the milk is coagulated to form a curd wherein 1/4 to 1/2 of the total serum proteins contained in the curd are the added heat denatured proteins, and the curd is drained to produce curd containing a total amount of serum proteins substantially equal to the total serum protein content of the starting milk. The addition of heat denatured serum proteins overcomes a problem of alternation in the normal ripening cycle of cheeses produced from ultrafiltered milk containing an increased quantity of soluble serum proteins.

  • Tapered vehicle bumper shim and method
    Patent number: 4270785
    Abstract: A shim is clamped between a component of a vehicle bumper assembly and a support member to provide a desired spacing for bumper alignment. The weight of the shim and the cost of material for its manufacture are minimized by forming the shim from sheet metal half the thickness or less of the desired spacing, and by folding the metal over inserts to provide multiple thicknesses in selected load bearing and other regions. A number of openings may be provided to further reduce the weight. Additional folded areas may be used for applications where loading is not restricted to areas adjacent the bolts, and ribs may be embossed in the shim to facilitate mounting of the shim and enhance its stiffness. The composite shim is finally "bumped" to give it a uniform taper.
