  • Patent number: 4531323
    Abstract: A hand propelled air glider type aerodynamic toy. The toy includes an elongated fuselage, a nosepiece which acts as a balance weight, a flat plastic or styrofoam member with an offset cutout which acts as the wings of the device, and a wing adjuster which secures the wing to the fuselage. The wing adjuster slidably accepts the fuselage to provide adjustments of the wing for different flight characteristics. The plastic fuselage passes through the cutout of the wing member thereby causing a slight upturn of the rear portion of the wing. The combination of the wing cutout and the angle of the wing construction with respect to the fuselage gives the device its aerodynamic properties.

  • Patent number: 4530571
    Abstract: A mirror made of a synthetic plastics material in the shape of a shallow tray having a base which is metallized on its internal or external surface. The shallow tray has a rim integral with the periphery of the base. The shape of the cross-section of the rim enables the peripheral edge at the front of the mirror to be convexly rounded to a required radius greater than the thickness of the base. The shape of the cross-section of the rim also serves to hold the base from distortion and so maintains the optical properties of the mirror.

  • Patent number: 4530217
    Abstract: The present invention relates to a defrosting device, for a refrigerator with a number of cooling compartments, which only supplies heat to the evaporator in the fresh food compartment when strictly necessary, that is, when fast defrosting is required, whereas it provides for natural defrosting as long as this is sufficient. In a first arrangement, fast defrosting is performed each cooling cycle but only for part of the time the compressor is off and only after a given temperature threshold has been exceeded by the evaporator in the fresh food compartment or by the freezer. In a second arrangement, fast defrosting is only performed for one out of "n" number of cycles. Both these arrangements provide for energy saving as compared with known technology besides improving fast freezing performance by reducing food freezing time again as compared with known technology.

  • Patent number: 4530493
    Abstract: The present invention provides a fastener assembly for use with a machine table having a work supporting surface and at least one elongated T-slot formed in the table and opened to the surface. The fastener assembly includes an elongated stud threaded at one end and a cross member secured transversely across its other end. This cross member is dimensioned to that it is insertable into the T-slot and thereafter rotatable within the wider portion of the T-slot. The fastener assembly further includes a U-shaped collar having an opening in its base through which the stud is slidably received. The collar is slid over the stud and into the T-slot whereupon the legs of the collar are positioned on opposite sides of the cross member and thus prevent rotation of the cross member.

  • Patent number: 4527152
    Abstract: An electronic security system to detect the presence of an object which has had a label affixed thereto when said object passes through a surveillance zone comprising an oscillatory electromagnetic interrogation field having three separate and distinct vector components produced by driving the transmitting coils located in housings on either side of said surveillance zone with an alternating power source repetitively in and out of phase with respect to one another so as to form magnetic lines of flux having one vector component in the in-phase mode and two vector components in the out-of-phase mode. The signals generated by the label are received by coils in said housing and are processed by electronic circuitry adapted to distinguish said label signals from spurious signals with a high degree of accuracy. The label can be deactivated so as to pass through the surveillance zone without triggering a system response.

  • Patent number: 4526283
    Abstract: A package closure includes a stopper adapted to be sealingly engageable with the opening of the package. The closure also includes a frangible member adapted to simultaneously seal the opening and carry the stopper in a disengaged position relative to the opening. Preferably, the stopper is engageable with the package opening in a child-proof manner. Breaking of the frangible member permits the child-proof package to be initially opened without requiring the package user to struggle with the child-proof stopper. The package contents may then be transferred to a package not having child-proof sealing means. Easy access to the contents of the package by the elderly or handicapped is thereby promoted.

  • Patent number: 4527018
    Abstract: A support for a one-piece telephone of a type incorporating in a single body all the equipment of a conventional two-part telephone, such as the apparatus, and the switch hooks normally positioned on or under the cradle for switching off the telephone when the handset is replaced. The support comprises a back plate having inclined end portions, one at an acute angle and the other at an obtuse angle with respect to the back plate, the former serving as an abutment for the switch hooks of the telephone, to actuate them to turn off the telephone automatically when it is replaced on the support, and the latter cooperating with a central saddle-like projection to define a cradle into which the earpiece of the telephone can be fitted and retained by means of slight flexure which is permitted by the material of which the device is made, that is a slightly resiliently or semirigid material such as a foamed plastics, rubber or the like.

  • Patent number: 4513997
    Abstract: An end fitting for an inflatable tube motor comprising plates each having a convex portion intermediate flat end portions, a resilient bushing having an elongated body with an enlarged central portion intermediate two substantially flat portions and a tubular fluid coupling having an elongated stem inserted in a throughbore in the enlarged portion of the bushing. The elongated body of the bushing is inserted into the end of an inflatable tube while one end of the tube abuts against a raised rib on one end of the bushing. A connector portion of the fluid coupling extends outwardly from the ribbed end of the bushing with the body portion of the bushing inserted in the end of the tube. The plates are placed over opposite sides of the tube end and pressed together to form a sealing engagement between the bushing and the tube end as well as the bushing and the fluid coupling, thereby permitting fluid communication with the interior of the tube only through the fluid coupling.
