Abstract: A watch mechanism incorporating two barrels each containing a spring. The springs contained in each barrel are positively connected in series to each other via a gear mechanism or a common arbor.The considerable energy available makes it possible to maintain the movement of a high frequency spring balance oscillator. The barrel rotates rapidly to drive the first pinion of the train of gears with an angular velocity approximately double relative to the normal angular velocities; the torque is approximately half (600 gr.mm) that of conventional-sized watch mechanism of comparable performance.The barrels may be mounted coaxially or in the same plane and the mechanism can be arranged to be wound manually or automatically.

Abstract: This invention provides a table air pot for keeping hot or cold liquid comprising a wide mouth vacuum-insulated bottle housed in an outer casing and supported by upper and lower supporting means respectively fixed on the top and bottom ends of the outer casing. The lid of the table air pot includes in combination a bellow-type pump device for pumping up the liquid contained in the bottle into a drink cup while the air pot stands upright on a table, and a plug fixed to the bottom of the pump device for closing the bottle when the lid in its closed position. The tube for discharging the liquid from the bottle in response to the operation of the pump device is fixed on the upper supporting means for the bottle and is physically separated from the plug of the lid. Thus, the table air pot according to this invention can become ready to be filled with liquid by a single operation of opening the lid without need of removing the liquid tube.

Abstract: The invention concerns the technical problem of providing a simple and reliable apparatus for separating castings from moulds of sand or similar material at the end of a guiding track, on which the moulds with the enclosed castings are advanced step by step towards a knocking-out station. With a view hereto the apparatus comprises a number of possibly interchangeable claws equipped with vibrators which, when moved into the row of moulds, can penetrate the mould sand and be caused to enclose and pinch the outermost casting, whereafter the claws are shifted back to the initial position in which the pair of tongs formed by the claws can open in order to deliver the casting for further treatment. The claws can be specially formed so as to retain possible core sand in the castings.

Abstract: A spray nozzle for use in the spray head of shower-bathing apparatus and primarily for use with high pressure water systems. The nozzle comprises a ducted body housing a swirl device having fixed guide vanes extending radially from a generally cylindrical hub and substantially flat guide faces angled relative to the hub axis which impart a swirling motion to water flowing through the body and which direct the water onto a converging wall and thence to a single nozzle orifice of right cylindrical configuration, whereby the water issues as a cone-shaped spray which is "full" of water droplets. The nozzle is suitable for use over a wide range of pressures above 1 bar (1 atmosphere) as the level of comfort of the user is maintained at the higher pressures.

Abstract: Apparatus is disclosed for treating pickling solutions used for pickling metal, such as iron, steel, special alloys, or the like. In a preferred embodiment, the apparatus includes an evaporator, a condensor, a crystallizer, a crystal-separating device, fittings and conduits for connection to the metal-treating plant, and a device for automatically controlling the evaporation rate in the evaporator. The evaporator includes a flow channel, vapor removal connection above the liquid level in the flow channel, an inlet and outlet for the solution being treated, and a plurality of electrodes for directly applying AC current to the solution. The electrodes are mounted spaced along the length of th flow channel and are completely covered by the solution so as to be out of contact with the vapor. The crystallizer comprises an upright cylindrical vessel having an inlet and an outlet, a driven shaft extending in the center line of the vessel, and is provided with radial ribs.

Abstract: A travelling grate conveyor for advancing a mould consisting of juxtaposed identical mould parts is associated with an endless mould supporting belt or conveyor formed by a plurality of closely spaced and interconnected rod members extending transversely of the longitudinal direction of the conveyor. The upper run of the belt rests on and is advanced by the travelling grate walking wacking beam conveyor.

Abstract: The locking device comprises a rod and cooperates, on the one hand, with a ratchet wheel fixed onto the winch drum and, on the other hand, with a flap comprising a spring and which is maintained in the lowered position by a breaking pane, destruction of said breaking pane freeing the flap which under action of the spring raises the locking device whereby freeing the ratchet wheel and the winch drum of which the cable freely unrolls under action of a motor opening the dome shaped member.

Abstract: Electronic timepiece with a device for indicating the time, which is electronically controlled and is used to display elements which simulate a game of chance. Additional circuits are provided for the control of the display of the elements of the game and at least part of the circuits of the timepiece, normally intended for the measure of the time are used in order to perform the choice at random of the elements.

Abstract: A conveyor on which a casting mould consisting of closely juxtaposed mould parts is advanced stepwise, comprises a section formed by an endless flexible belt. Extending along the side edges of this belt are reciprocating coupling parts which during at least part of their forward stroke are firmly clamped to the edge portions of the belt, from which they are released during their return stroke. In this way elastic extensions and retractions of the flexible belt are excluded.

Abstract: Electronic watch provided with a release circuit in order to reduce the consumption of energy of the watch in its stocking condition. The release circuit is controlled through a delay circuit by a logic control circuit which is set in a particular "stocking" position by control means.

Abstract: A flow control device for controlling the rate of flow of fluid passing through flexible tubing used in particular for intravenous administration sets. The device comprises a body member with a bottom and two side walls defining a tubing receiving channel. The side walls are provided with aligned bearings journalling pivot means pivotally supporting a lever having at one end a semi-circular cam-like clamping disk substantially concentric with the pivot means. One edge of the leading portion or initial tube engaging clamping surfaces of said disk is rounded with the radius of curvature of said edge decreasing continuously, forming thus a clamping surface which will, upon movement of the lever, first collapse and deform the tubing into a L-shaped cross-sectional configuration and then press together the horizontal and then continuously the vertical part of the tubing. This device provides for an easily adjustable and unvarying flow rate.

Abstract: The present invention refers to a shaft packing, in particular for use in colloid mill, with a sliding and a counter ring, one of the rings is made of a hard material having a Vickers hardness of at least 1,000 kp/mm2 and the other is made of a soft material having a hardness of 100 Shores at the most. In particular the surfaces in contact with each other are cooled and lubricated by a liquid. In order to further increase the life of said packing, the counter ring is displaceable and adjustable from the outside without being dismantled and the sliding ring holder is provided with centrifugal blades for keeping the material to be milled and milling bodies away from the contact surfaces of said rings. The construction of said shaft packings allows its use in a horizontally arranged colloid mill, wherein the material being milled flows in the direction of the widening cone.
