Abstract: Apparatus for filling a toilet tank with water and discharging the water therefrom has a valve base for supplying water to the toilet tank. A valve is in a hollow passage of the valve base for closing the hollow passage to the supply of water when pulled vertically. An axle is connected at one end to the valve plug. An axle floater is on the opposite end of the axle for pulling the valve vertically when the toilet tank is full of water. A buoy base discharges water from the toilet tank. A discharge buoy closes the buoy base until pulled from the buoy base, and then floats on the water in the toilet tank back to the buoy base as the water is discharged. A pulling chain connects the discharge buoy to a command lever which is tiltable by a command handle on the outside of the toilet tank to pull the discharge buoy from the buoy base with the pulling chain. The command lever also engages the axle, to tilt the axle when the command lever is tilted, which opens the valve for supplying the water.

Abstract: An electric toaster wherein the housing defines a toasting chamber for slices of bread or other goods and the chamber has an outlet for toasted goods at or close to its lowermost portion. The chamber is flanked by two ceramic panels which can store substantial amounts of heat and transmit infrared radiation. Each panel defines with a semicylindrical reflector a compartment for one or more halogen lamps which emit radiation directly against the respective panel or indirectly as a result of deflection by the corresponding reflector. Gravitational descent of goods from the chamber can be blocked by a gate- or rod-like barrier which is movable into the outlet by hand or automatically in response to completion of a toasting operation.

Abstract: In open-end rotor spinning, imparting lesser false twist to the yarn being formed as it revolves through the yarn receiving zone and greater false twist as it revolves away from the zone. This is accomplished by different frictional resistance surface characteristics on the surface of a navel, or by shaping the surface for lesser extent of yarn contact in one surface portion and greater extent of yarn contact in another surface portion.

Abstract: Process for the purification of products of regenerated cellulose in which the regenerated cellulose product is passed through at least one washing segment where it is initially squeezed out with the aid of a squeezing element and then washed out with the washing water, passed in counter current, while simultaneously being deflected over deflection elements.

Abstract: In the case of a process for piecing at a spinning unit that is used for producing feed spools consisting of multiple-wound, prestrengthened slivers for a subsequent twisting operation or the like, it is provided that first the supply of the drafting roller device is started, after which the slivers are sucked into the pneumatic false-twisting devices, are guided through them and are then jointly gripped at the outlet of the false-twisting devices, are placed in a withdrawal device and are then fed to a winding-up device.

Abstract: A continuous multifilament crimped polyamide or polypropylene yarn suitable for use in loop pile carpeting and the process for making the yarn including feeding the yarn at different tensions and then treating the yarn with saturated steam is disclosed.

Abstract: A textile winder has manually actuatable yarn air splicers mounted on the winder closely adjacent the path of travel of the yarn from its source to the yarn package being wound. The yarn air splicers mainly serve for connecting the yarn from the trailing end of the relatively large package being wound to the leading end of the yarn from the source of supply, such as skeins of yarn carried by a creel.A yarn end severing means is mounted adjacent each yarn air splicer for severing the ends of the yarn to be spliced so as to obtain substantially coextensive yarn ends for facilitating splicing and obtaining more effective splicing. Manually performed methods of operation of the yarn air splicer and associated yarn end severing means by the winder attendant are also disclosed.

Abstract: The process and apparatus of our invention reduces the breakdown quota of stopping devices in a spinning or twisting machine which stop the roving, e.g. when a roving break occurs. A simulated signal for "Yarn Running" is conductable to a stopping device for test purposes and/or the yarn break sensing device can be disconnected from the stopping device and from time to time a connecting signal is produced which reconnects the yarn break device to the associated stop device.

Abstract: Method to produce a spun-like textured yarn comprised of one yarn which is substantially fully oriented and the other yarn is partially oriented. The method involves plying the yarns in the draw zone before being pre-textured. The ply point of the plied yarns is located above the entrance to the heater in the draw zone.

Abstract: An open-end friction spinning machine is provided having a plurality of spinning units arranged next to one another. A suction device assigned to each spinning unit which acts in the area of the yarn formation zone may be selectively switched off such as in the case of a yarn breakage. So that the air throughput balance does not change in the area of the other spinning units when the suction device of a single unit is switched off, devices are provided for maintaining the air throughput relatively constant. Air throughput normally used by the suction devices in the yarn forming area of the spinning unit is diverted, for cleaning and maintenance purposes.

Abstract: A process and machine for making a cord in a structure of one or more layers of filaments, all twisted with a same twist pitch p around a core in which the filaments are not twisted around each other with that same twist pitch p. The cord is made in one continous process in which the core filaments are bundled in a twister, then the layer filaments are joined in parallel to the core bundle on exit from the twister, and the whole is then twisted in a double-twist bunching machine.

Abstract: In the manufacture of a cable having a plurality of filamentary members such as wires, optical fibres or the like within an extruded thermoplastic sheath the members are twisted into a periodically reversing helical configuration immediately prior to the extrusion of the sheath around them, and the extruded sheath is rapidly cooled on emergence from the extruder head so as to cause the extrudate to set and thereby retain the members in the twisted condition.

Abstract: There is disclosed an inner shoe for a molded ski boot which includes a foot warmer mechanism having an electrical resistance heater, an electrical generator, a mechanical translator to translate vertical movements of the wearer's heel into uni-directional rotational movement of a flywheel, and a gear box mechanically coupling the flywheel to the electrical generator. Specific features of the mechanism include: a shock absorbing resilient coupling of the flywheel to prevent damaging the mechanism while juming or otherwise subjecting the shoe to hard usage; interchangeable generators and gear boxes to accommodate wearer's of varied size and weight as well as for varied intensity of activity; and an entirely sealed, remote latch to lock the mechanical drive out of operation.

Abstract: For piecing to an open-end friction spinning device with two friction spinning elements normally driven in the same direction of rotation and forming a nip therebetween, of which friction spinning elements at least one is capable of being subjected to suction, fibers are continuously fed to the nip and are then immediately removed from same. While fiber feeding continues uninterruptedly, the removal of fibers from such nip is then discontinued, so that fibers remain in the nip and form a rotating accumulation of fibers. A yarn end is then introduced to such accumulation of fibers. Newly formed yarn is then drawn off from the nip while fibers being fed continuously to such nip are continuously formed into such yarn. For such removal of fibers, a controllable suction air nozzle may be directed towards the above-mentioned nip from a side of the friction spinning elements opposite such nip.
