Patent EP-0269098-B1 (EP)
IPC: A63H17/26
Filed: 1987-11-25
Granted: 1992-10-07
Abstract: A wheel bearing, in particular for toy vehicles, which are usually subjected to strong overloads, is characterized in that, in the vicinity of each end, the wheel axle (10, not shown in fig. 2) has both a bearing face (14, 15) with a relatively small radius of curvature and a bearing face (12, 13) with a relatively large radius of curvature substantially corresponding to the radius of the axle. The bearings with the small radius of curvature (14, 15) are elastically resilient, the bearing faces with the relatively small radius of curvature being provided in bearing plates (2, 3) which are connected with a vehicle portion (1) via elastic connecting members (4, 5). When the toy vehicle is overloaded, the axle is supported in the large bearings (12, 13) so that the small bearings (14, 15), having a very small friction under normal operating conditions, are not damaged.

Granted: 1991-10-16
Abstract: The cutting tool comprises a shank with an interchangeable square or rhomboidal body of hard cutting material, with a top chip face (1) and peripheral faces (2) forming the clearance face. The chip face has a chamfer (4) at the cutting edge (3), parallel to the latter and approx. at right angles to the respective clearance face, behind which are protrusions and recesses. The rake angle, adjacent to the chamfer, is greater than 30 deg. and reduces with increasing distance from it to zero when this distance is equal to three times the chamfer width. In the sections (6) between the cutting corners (5), chip ribs (11) protrude from the chip face at intervals in the lateral direction (10), extending in the chip travel direction, starting at a distance (9) from the chamber roughly equal to the width of the latter. Their smoothrfaces (12) are at a rake angle less than that of the chip face where it joins onto the chamfer, while their leading edges (14) nearest to the cutting edge protrude roughly level with the chamfer. The surfaces (15) between the ribs have ramps (17) leading to bosses (16) also protruding to this level.

Abstract: It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to detect increases in transient D.C. current flowing in the respective phases of a distribution cable (10) feeding a transformer and also to detect increases in other selected functions of supply parameters for identifying and quantifying a fault current flowing in the distribution cable (10). Increases in these other functions are analysed to identify whether the increases indicate a fault current. Any such fault current can then be quantified and the triggering of a circuit breaker (19) initiated to isolate the supply cable on identifying a fault current. The circuit breaker (19) is not triggered for any increases in the other functions for as long as there is a detected increase in D.C. current in any phase.

Abstract: A resin moulding is produced by introducing molten synthetic thermoplastic resin (19) into a mould cavity (13), sufficient to fill completely the mould cavity. Subsequently, during the cooling of the resin, pressurised gas is introduced into the resin within the mould cavity. The resin moulding cools and hardens in the mould cavity whilst the gas is maintained under pressure. The mould cavity is designed to manufacture mouldings with unevenly distributed thick walled sections (3) connected to at least one gate (4;44) for the introduction of the pressurised gas, which flows only within the resin forming the thick walled sections and immediately adjacent areas of the moulding thereby taking up the shrinkage in the resin.

Abstract: A recirculating fiber filter (1) and method is provided for removing particulates from moving fluid streams. High aspect ratio fibers (2) are used which readily nest with each other to form the high voidage fiber filter bed. In the method, fibers are continuously removed from the bottom of the bed regenerated to remove particulates and recycled back to the top of the bed and distributed thereon. Dirty fluid is passed from the top to the bottom of the filter. Dendrites of the particulate impurity appear to buildup in a thin section (A) at the top of the filter and provide the primary mechanism for further particulate entrapment. Recirculation of fibers offers a continuously fresh volume of fibers at the top for capture of particulates.

Abstract: The pliable portion of the article (80) has a first end portion (1) and a second end portion located at opposite ends of the encircling portion of the article. The first end portion (1) includes an elasticized fastening system (120) having at least one segment (15) which is capable of being elastically shirred along at least a portion of its length. The shirrable portion of the segment (15) comprises an elastomeric member which, prior to the securement of the first and second end portions of the article to one another, is maintained in a prestretched and tensioned condition in the desired direction of shirring. The opposed ends of the shirrable segment in the article (80) are interconnected to one another through the prestretched and tensioned elastomeric member. The prestretched and tensioned elastomeric member is maintained in tension by securing it in fixed relation to at least one rigidifying member (28) to form a composite structure which is strong enough to resist collapse in a direction parallel to the tensile forces acting upon the prestretched and tensioned elastomeric member. In a particularly preferred embodiment, the rigidifying member (28) has a fixed portion (30) permanently secured to the first end portion (1) of the article (80) and a releasable portion (32) which can be separated from the first end portion of the article. The releasable portion (32) of the rigidifying member (28) preferably includes means for securing it to the second end portion (2) of the article (80), and the act of affixing the releasable portion (32) of the rigidifying member (28) to the second end portion (2) of the article (80) automatically releases the tension in the prestretched elastomeric member. Elasticized fastening systems of the present invention can be produced at high speed from continuous webs and cut into discrete segments which are transferred onto a continuously moving web at predetermined points along its length, all while the elastomeric member is maintained in its prestretched and tensioned condition by the rigidifying member.
