Abstract: The invention relates to a circular carriage track guide for a braiding machine. The braiding machine has at least two supply spool support sets performing relative movement with respect to each other about its rotational axis during braiding, wherein the spool supports (16) of one of the spool support sets are guided by the carriage track guide and the carriage track guide comprises a carriage (20) for each spool support (16) for attachment thereof. The carriage track guide comprises a set of outer rollers (6) for the outer radial guidance of the carriages (20), said outer rollers being attached to a support plate (4) of the carriage track guide such that an outer surface (70) of the respective carriage (20) can roll on a surface (38) of the outer rollers (6) which is mounted so as to be able to rotate by means of at least one roller bearing.

Abstract: A power cutter including a two stroke internal combustion engine mounted within a housing and a carburetor for providing aerated fuel for the engine. The carburetor is capable of operating in at least two modes of operation, a first mode when the engine is cold and a second mode when the engine is hot. A temperature sensor is mounted on the engine and provides an engine controller with a signal which is a function of the temperature of the engine; the carburetor comprising an electrically controlled cold start mechanism which switches the carburetor between its two modes of operation, wherein, when the electronic controller determines that the engine is cold, it provides an electrical signal to the electrically controlled cold start mechanism to cause it to change the mode of operation of the carburetor to its first mode.

Abstract: A computer network comprising a plurality of terminals (1–4) connected via a communications network 5 is provided. In each of the terminals (1–4) application software (15) for generating XML source documents is provided. XML source documents created using the application software (15) are then sent to one of the terminals (4) having stored therein a consistency checker (10). The consistency checker (10) processes the source document together with a set of consistency rules (14) to generate an output presentation identifying data within the source documents which does or does not fulfil the requirements of consistency relationships defined by the consistency rules (14).

Abstract: The present invention relates to a braider (1) comprising a device for controlling the thread lever (10). Said braider is formed by a curved path (30) that is closed in a circular ring-shaped manner, a sliding block (31) appurtenant thereto and a reverse gear (20) by means of which the direction of rotation of the drive motor is reversed in such a way that the group of the upper delivery bobbins and the group of the lower delivery bobbins rotate in opposing directions. The aim of the invention is to enable such a braider (1) to have a higher ceiling speed.

Abstract: A braiding machine has a support defining an upright axis, a lower rotor rotatable on the support about the axis and defining an annular guide centered on the axis, and an upper rotor having slides bearing at an interface on the guide and rotatable on the lower rotor about the axis. A drive connected to the rotors rotates same in opposite directions about the axis with the slides sliding on the guide. Dosers feeding a lubricant to the interface and a sensor detects a temperature of the guide at the interface. A computer-type controller connected to the doser and to the sensor feeds the lubricant to the interface at a rate only sufficient to prevent the detected temperature from exceeding a predetermined limit.

Abstract: The instant invention is a lubricating system used in a braiding machine having a pair of relatively rotating parts sliding on each other at a location. The system has a stationary tube shaft extending vertically as a single piece along an axis and formed with a passage having an axially extending section and, extending therefrom, a radially outwardly open section. A pump supplies a lubricant fluid under pressure to the axially extending passage section and a distributor star fixed to one of the parts has a flow passage with a radially outer end at the location and a radially inner end. A bearing supports the star on the shaft for rotation about the axis with the inner passage end of the star opening into the outwardly open passage section of the shaft so that fluid from the pump flows along the shaft passage and then along the star passage to the location. Seals between the star and the shaft axially flank the inner passage end of the star.

Abstract: The present invention relates to a sealing element for an internal combustion engine, preferably a two-stroke engine, having a crankcase with an upper part and a lower part in which two roller bearings for the crankshaft are disposed between the upper part and the lower part. The roller bearings are encompassed by rings made of a heat resistant, thermoplastic material; each of the rings is provided with a groove running around its outer circumferential surface, and each groove receives a sealing element. The sealing elements are part of a shaped sealing part received between the upper part and the lower part, which shaped sealing part has an essentially circular cross section and is made of an elastomer material, and which, in the region between the two rings extends within another groove which is provided in the upper part and/or lower part.

Abstract: Apparatus for feeding tacks to a heel lasting machine has one or more slideways which deliver series of successive tacks from discrete receptacles to selected axially parallel flutes in the peripheral surface of a rotor in such a way that the shanks of the tacks enter the flutes and the heads of the tacks overlie the upper side of the rotor. The peripheral surface of the rotor is surrounded by the internal surface of a stationary housing which has a set of pockets for reception of entire tacks from the rotor. The transfer of tacks from the rotor into the pockets of the housing is effected pneumatically, and the conveying of tacks from the pockets into the lasting machine takes place by gravity and/or pneumatically. The apparatus has a discrete stop for the discharge end of each slideway; such stop or stops can be actuated to bias the head of the adjacent tack against the upper side of the respective slideway and to thus interrupt the delivery of tacks from the respective receptacle to the rotor.

Abstract: Apparatus for pulling the lasting edge of a lasted shoe upper over an insole has at least one flexible elastic shaft one end portion of which is anchored in a motor-driven rotor and which is loosely surrounded by a helical spring. One end of the spring is anchored in the rotor and its other end is movable axially of the shaft toward and away from the one end. The spring yields in response to the application of an excessive pull to the lasting edge and thus prevents overstressing of the lasting edge and/or the development of wrinkles.

Abstract: A rivet bucking tool (10) is provided with a damping piston (13) having a skirt (18) thereon and in which the shank (25) of a rivet bucking die (23) is freely removably received. This allows easy exchange of the dies (23) for piston recoil adaptation to rivets of different size and material. The area transformation between the shank (25) and the damping piston (13), the skirt (18) thereon, and the preferably airtight frictional fit of the skirt (18) around the shank (25) are utilized to convert bucking stress into vibration so as to reduce joint recoil of the damping piston (13) and die (23) during bucking. Vibration and recoil are absorbed in the tool housing (11) by compressed air in a damping chamber (42) wherein the pressure is selectively adjustable by a valve (28).

Abstract: A rivet bucking tool (10) is provided with a damping piston (13) actuated by air pressure in a damping chamber (42) of the tool housing (11) of sufficient volume to isolate the housing (11) from undesirable vibration. The piston (13) forms an assembly with a bucking die (23) so as to inertially restrain recoil jointly therewith. A pressure reduction valve (28) is provided on the tool (10) for selectively setting the pressure in the damping chamber (42) to produce an elastic force bias on the assembly approximately equal to the optimal manual bucking force required for properly forming the rivet head and bucking in the riveting work at hand.
