A tip assembly has a replaceable wear member mounted to an adapter carried on the cutting edge of an implement of an earth-working machine. The adapter has an external surface formed to engage a complementary internal cavity of the wear member and includes a pair of transversely spaced sides at least one of the transversely spaced sides include a guide arrangement and a retainer pocket positioned therein. The wear member has a body with an exterior ground-engaging surface, a mounting end, an adapter receiving cavity and at least one ear extending from the mounting end. The at least one ear is configured to be received by the guide arrangement when the wear member is positioned on the adapter.

Pin retainers are normally used to secure a pin in its assembled so that one member can be releasably secured to another member, such as, securing a tooth to an adapter nose. Many times the pin retainer is not sufficiently strong to hold the pin in place under adverse operating conditions. Known pin retainers that are effective to hold the pin in place are not readily available and are expensive to produce. In the subject arrangement, a pin retainer assembly is provided which can be made from known components and is effective to hold a pin in place under adverse operating conditions. The pin retainer assembly includes a split retaining ring loosely sandwiched between at least two retaining members and held together by various known bonding or securing methods.

Spheroidal particles of wear-resistant alloy comprising boron, chromium and iron having maximum hardness for a given composition are produced by the rapid cooling of a molten alloy mixture. The resultant solid particles are then incorporated into a composite alloy wherein the solid particles are held together with a matrix of different material from the alloy. Inserts of the composite wear-resistant alloy are useful in producing long wearing tools.

A mechanical retention system is disclosed for detachably retaining a ground engaging tool onto an earthworking implement. The retention system uses an elongated steel retainer, which has a convolute spring portion between opposite the end portions of the retainer to allow the retainer to be compressible in one direction in order to be mounted through a retainer opening in the tool into a retainer pocket in the mounting portion of the implement.

A method of and means for cutting hose of the type designed for use in high pressure hydraulic systems is disclosed in which the impingement of a high power laser beam is moved about the periphery of the hose in a plurality of passes. An embodiment is described in which the hose remains stationary with the beam being moved thereabout and a further embodiment is disclosed in which the beam remains stationary and the hose is rotated about its own axis. The provision of inert gas to prevent combustion both inside and outside the hose during cutting thereof is disclosed.

A wear-resistant alloy comprising boron, chromium and iron having maximum hardness for a given composition is produced by rapidly cooling and solidfying spheroidal particles of the molten alloy mixture. The resultant solid particles are then cast in the desired form, or incorporated into a composite alloy wherein the solid particles are held together with a matrix of different material from the alloy.
