Abstract: A closing control and opening free assembly for a hinge connection is mounted within various articles of furniture or implements. The assembly has a mounting element having a circular hole, a pivot member or rotor disk connected therewith, the circumference of which gets into contact with the inside surface of the circular hole, one or more pair of spring and roller positioned in each of recess formed on the periphery of the circular hole or the pivot member, and a brake component. When opening a rotatable section upward, the pivot can rotate together with the brake component, and thus it is possible to open freely the rotatable section. When closing the rotatable section downward, the pivot can not rotate with the brake component. Consequently, the rotatable section is rested at a desired turning position.

Abstract: In an electrical appliance for treating food products, the safety device which prevents access of the user's fingers to the tool mounted in the bowl when the motor is operating, is actuated by a rotating cam which, via a rod and ring, acts on the lid of the bowl. It is the lowering of this bowl which effects actuation of the angular immobilizing mechanism connected to the shaft of the motor and/or to the shaft of the tool, as well as control of the contactor connected to the circuit which supplies the motor.

Abstract: An assembly for controlling turn of a hinge is mounted within one section of a hinged structure such as a laptop, palm-top or handy personal computer. In the assembly housing, there are arranged an elongated pivot, a cylindric plastic sleeve having an aperture for setting the pivot, and a socket having a frusto-conical aperture. The sleeve is usually of a truncated biconical shape and has some slot extends axially to one or other end thereof. The inner surface of the housing bore inclines axially in the opposite direction to the inner surface of the socket so that the inclined inner surface can contact with the other frusto-conical outer surface of the sleeve.

Abstract: A guitar pick having a serrated or jagged edge for picking a guitar string and capable of producing in a rapid succession a repetitive tone to give a percussive effect and to alternatively pick normally by using the unserrated top portion of the pick. The serrations may be on a beveled surface, may extend along about a 1/2 inch of the length of the guitar pick and be on both sides of the pick.

Abstract: A method of operating a combustion plant including a reactor, e.g. a fluidized-bed reactor which transfers heat form a fuel to a granular medium, such as sand, and wherein a part of the heated medium during operation is discharged from the combustion chamber (2) of the reactor (1) and supplied to a heat-producing heat exchanger (11). The plant further includes a storing means (9) which is connected to the combustion chamber (2) of the reactor (1), and a part of the discharged hot medium is transferred to the storing means (9) which stores the medium in order to accumulate the heat therein. In case of increased energy demand, hot medium is supplied from the storing means (9) to one or more additional heat exchangers (28, 29, 30) for supplementing the heat production of the first-mentioned heat exchanger (11).

Abstract: In a door closer, there are provided a vertical rotatable shaft associated with the rotation of a door through an arm, two cams installed integral with the shaft, an urging device for rotating the door in the closing direction through one of the cams and a cylinder device for braking the door during door closing operation through the other of the cams. Thus, the opening of the door is effected by overcoming the force of the urging device and hence the door can be opened lightly. When the door is released, the force of the urging device is transmitted to the one cam and then to the arm, so that the door can be automatically closed. During door closing operation, the cam surface of the other cam pushes the piston rod of the cylinder device, whereby the rotation of the other cam and hence the rotation of the shaft connected with the other cam are braked, avoiding severe shocks to the door.

Abstract: A hinge-type lid mounting device has a main body to be attached to a case or the like, and the main body has at its one end a cam body pivotally mounted through a first pin. The other end of the main body defines a fixed spring seat, and a spring is interposed between the fixed spring seat and a movable spring seat adapted to abut the cam body. A lid supporting member is rotatably mounted on the cam body through a second pin perpendicular to the first pin. A lid is anchored at its one end to the lid supporting member through a lid anchoring member and a fixing screw.

Abstract: A hinge device comprising a main body in the form of a channel member, a mount pin projecting outward from the web of the main body, and a pressing plate pivoted at its one end to the inner side of one side wall of the main body and retractable into the channel of the main body, the pressing plate being provided with a wedge formation on one side surface thereof opposed to said one side wall of the main body so as to gradually approach the other side wall of the main body as the pressing plate is retracted into the channel of the main body. A plate, such as the closure plate of a cabinet, can be loosely fitted into the channel of the main body with the pressing plate withdrawn therefrom and can be tightly held in the channel by the wedging effect produced when the pressing plate is retracted. The hinge device can be installed in place easily and yet holds the plate reliably.

Abstract: The invention refers to a ski boot made from synthetic plastic material, with separate boot and leg portions.The ski boot according to the invention presents a leg portion separable from the boot, comprising a part higher than the ankles and a lower part rigidly bound to the sole. The two parts of the leg portion may be built in a single piece or separately. In the latter case, the two parts are articulated to each other in the ankle region by means of pivotal pins.The ski boot according to the invention overcomes the drawback presented by the previously known ski boots, wherein the boot's articulation area dilates as a consequence of the fore rocking of the leg portion, and thus reduces the clamping action of the boot on the skier's foot, just when the skier's leg is expected to transmit the strongest thrust to the ski, through the ski boot.
