A coating is formed on a substrate by sputter ion plating wherein a DC glow discharge is generated under soft vacuum conditions in the presence of the substrate and of a cathode constituted by the coating material thereby to release material at the cathode by ion bombardment, which released material diffuses to the substrate to form the coating thereon, and wherein a potential is applied to the substrate during coating. In order to control the coating, for example when it is an alloy containing ...

Valve assemblies having a valve seat with a conical surface for causing an included O-ring to roll upon and wedge against the conical surface for closing the port when a spherical valve member is forced against the O-ring.

There is disclosed a coupling for tubular members such as conduits, hoses and the like which provides for the rapid connecting and disconnecting of the members. The coupling comprises a body with a through opening and bearing attachment means at one end and an annular groove at the other end with a plurality of segmented and arcuate jaws having an inboard flange seated in the annular groove to provide a radially pivotal support of the jaws on the body. The outboard ends of the jaws bear tubular ...

An improved, horizontal, continuous contacting-mixing device utilizing internal circulation and having therewith an impeller, a circulation tube and (usually) an indirect heat exchanging tube bundle; an improved type of horizontal circulating, mixing, reaction vessel or contactor; in a horizontal contactor vessel where the impeller is received in lesser internal diameter shell and circulating tube zones, offsetting the cones of the outer shell and circulation tube downwardly at the impeller end ...

A tool and cooperative work table and pattern support means are described which can be used with a lathe to permit accurate duplication of turnings or of two dimensional patterns. The pattern support means are operative to secure a pattern beneath and in vertical alignment with the work center of the lathe; the table provides an offset surface for support of the tool; and the tool has a base plate with a first arm that supports a pattern follower and a second arm which supports the cutting tool ...

A toilet that has an improved vacuum breaker assembly wherein the vacuum breaker casing has integral hinge posts for the toilet cover. The improved vacuum breaker assembly is snap-fitted into place on the toilet housing and is secured in place against displacement in any direction.

A process for tanning hides or skins comprises first treating the hides or skins with a basic salt of a multivalent metal; and then treating the hides or skins with a reaction medium containing a water-soluble salt of a dibasic organic acid, the water-soluble salt being one that forms an alkaline solution in water, and being present in an amount sufficient to maintain an alkaline pH in the reaction medium.

Feedback cancellation apparatus uses a cascade of two filters along with a short bulk delay. The first filter is adapted when the hearing aid is turned on in the ear. This filter adapts quickly using a white noise probe signal, and then the filter coefficients are frozen. The first filter models parts of the hearing-aid feedback path that are essentially constant over the course of the day. The second filter adapts while the hearing aid is in use and does not use a separate probe signal. This fi...

A disc plow having a stump jump capability. The plow includes a frame and at least one trailing arm secured thereto. The trailing arm supports at least one concave disc thereon. In use, the concave disc attached to the trailing arm has a working position in which the concave side of the disc is inclined so as to be open to any approaching soil and, a release position in which the concave side of the disc is directed at right angles to a forward to rearward alignment of the plow.

Improved vehicle restraints, restraint components and specific improvements to certain existing restraints, including: 1) improvements to the design of the barrier portion or head of the restraining member intended to prevent or eliminate downward forces exerted on the restraining member by a departing ICC bar; and 2) providing a locking member for locking the restraining member of a restraint into a given vertical position for a pull away by the parked vehicle, the lock not impeding normal oper...
