Abstract: An apparatus is provided for cooking and browning foods such as roasts, fowl, hams and bacon, etc. in a microwave oven. The meat to be cooked is supported on ribs on the upper surface of a cooking vessel, the ribs defining grooves for the flow of liquid fat drippings from the meat being cooked. The grooves cover most of the upper surface of the vessel and so underlie most of the surface of the meat. They feed into a channel leading into a main reservoir.Fat absorbs more energy from microwave radiation than meat and so reaches a high temperature far more quickly than the meat. The presence of the fat, as a result, reduces absorption of direct and reflected microwave energy by the leaner meat, and so should be conducted away from directly below or around the meat area, to a position remote as possible from the meat.The vessels of this invention conduct liquified fat from the meat, so the meat is not shielded, and use the fat as a source of heat for the air in the oven.

Abstract: A child's toy construction system, similar in purpose to "Erector" sets, is provided having reusable, distensible "rivets" instead of nuts and bolts, and a rivet "gun" to provide a feeling of authenticity in use.The system includes plates and bars to be joined together to create different structures. They are joined by use of the rivets passing through aligned holes in the plates and bars.The rivets are formed of bullet-shaped, soft distensible rubber pieces having a bore passing lengthwise through the rivet, but being closed at the leading end. The rivets have an outside diameter greater than the diameter of the holes, when the rivets are in their relaxed, undistended condition, and will, therefore, when not distended, expand to fill the holes and secure the pieces together. Their diameter is less than that of the holes when they are longitudinally distended. The base of the rivets is larger than the holes and includes an undercut gripping shoulder.

Abstract: A lawn treating spreader cart is provided capable of carrying, measuring, mixing, and spreading multiple lawn treatment materials while, at the same time, being compact enough for hand operation. This is accomplished by positioning bins of various treatment materials transversely across the width of the chassis. The bins have proximate, transversely positioned outlets for depositing measuring quantities of treatment material upon a forwardly moving belt, these being spread over a wide area by an adjustable rotor. Means are provided for adjusting the width of the area to be treated and for temporarily stopping the spread while the cart is being moved.

Abstract: The invention relates to a machine for making containers from glass tubes, with several chucks circulating through a succession of processing stations, each chuck having jaws to grip a glass tube or container, and with the chucks being brought successively to a position in which they are superposed above a stationary supporting plate at at least one processing station, this plate being for limiting downward movement of the length of tube which falls downwards through the chuck, wherein the chucks move up and down on at least one circulating column, the processing station which has the supporting plate being equipped with a senser which triggers a releasing device which releases the chuck which has reached this station, so that it moves downwards, the senser responding to the absence of a tube above the upper surface of the jaws of the chuck by initiating downward movement of the chuck.

Abstract: An intrusion alarm is encased within a housing hung from a doorknob by a conductive strap which makes electrical contact with the doorknob apparatus. A monitoring circuit within the housing is connected to the hanging strap for sensing capacitance changes corresponding to touching of the exterior portion of the doorknob apparatus by a would-be intruder. Alarm means within the housing are activated by the monitoring circuit to generate a local audible alarm or an FM transmission signal sent to a remote receiver or both. A latching circuit maintains the alarm means in an activated state after the capacitance coupled to the doorknob apparatus has been removed, and switch means on the exterior of the housing are provided for resetting the alarm to a non-activated state to permit sensing of a subsequent capacitance change. The alarm further includes means for temporarily disabling the alarm device for a predetermined period of time during which it may be touched without activating an alarm signal.

Abstract: A children's game is provided in which plastic animals, such as turtles, are used as playing pieces and race along the track of a game board, advancing a given number of spaces on the basis of the spinning of a dial. The game board, however, is round and rotatable and has a base with randomly positioned magnets under the spaces on the board. The playing pieces also include magnets which are affected when they are on spaces over the random magnets. In particular, the playing piece is designed so that the animal's head drops when over a magnet, so it "falls asleep." The animal can then be "awakened" by rotating the board the equivalent of one space and so removing it from the magnet. In doing so, however, another player's piece may be moved over a magnet and similarly "fall asleep".

Abstract: A convenient, useful and efficient method and apparatus for determining the amount of alcohol contained in fuels. It is particularly useful for measuring the alcohol content of jet fuel, and is practiced by mixing a known amount of the fuel to be measured with a known amount of emulsion, the emulsion comprising a known amount of 8-Hydroxyquinoline ester of the O-vanadic acid. A resulting reaction causes a portion of the mixture to discolor, the amount of discoloration indicating the alcohol content of the fuel. This process can be performed in an apparatus comprising a tube with all of the necessary chemicals pre-mixed, thereby only requiring the addition of the fuel to be tested. Such an apparatus can be prepared in advance, sealed, and stored for a period of up to 2 years.

Abstract: A tire chain with separable chain strands the end links of which are connectable at each separation point by use of two connecting elements which can be hooked into each other and which are each safely connected with an end link, wherein each connecting element has a body comprising at least one portion bounding an insertion slot which portion has a cross-section decreased at its free end at the expense of its width and wherein the width of the insertion slot is smaller than the height of each of those portions of the body which bound the insertion slot.

The carrying device has a framework forming upper and lower lifting regions, preferably located to rest upon the shoulder and against the hip. The framework additionally defines a plane against which a sheet of material may be placed, and pivotally supports, adjacent said plane, cam means which are mounted eccentrically, arranged to be gravitationally rotated into gripping engagement with a sheet of material placed against said plane, and arranged to be rotated into tighter gripping engagement by gravitational forces exerted on the sheet of material as the framework is lifted upwardly.

Abstract: A new treasure hunt game is played by concealing magnets in a game board and passing a detector assembly in a path over the game board to provide a concealed stored indication, retrievable later, that the detector's path has intercepted a concealed magnet. The detector assembly includes a pivotable indicator having two gravitationally stable positions, and magnetic means in the indicator for pivoting it from one stable position to the other stable position as the magnetic field of a concealed magnet is encountered. The indicator remains in its second stable position after once passing over a concealed magnet to store the indication. A housing with a retractable cover encloses the indicator, and a cushioned stop for the indicator absorbs noise and vibration, so that an indication is hidden from a player moving the detector assembly until a selected juncture in the game.
