A connector for use in splicing multi-strand shielded cables, particularly designed for interconnecting the shields thereof. Here the connector is provided with a protruding tang providing a secondary current path between the shield and the connecting strap.

A series-loop cooling system for cooling individually several zones within a building or several buildings includes a closed circuit having for each zone and within series in the circuit the heat exchange coil of a heat exchange unit which utilizes and incorporates the standard structural members of a building or of several buildings. A cooling medium is circulated continually through the circuit and the heat exchange coil of each heat exchange unit and thermostatically controlled fans in each h...

A voltage regulator in which power is transferred to the resonant circuit of a parametric device by both the parametric mechanism and either flux coupling or direct coupling or both. The device includes a core on which are wound an input winding and at least one output winding which forms part of the resonant circuit. This winding is parametrically coupled to the input winding. Another output winding on the core is connected into the resonant circuit and flux coupled to the input winding, or alt...

There is disclosed herein an economical method and system for transmitting color video information over relatively low bandwidth transmission facilities. Original color material such as color motion pictures, stills, or slides of data, news events, or the like, or live pickup of such events, is converted to field sequential video information through the use of passive field sequential pickup and sending equipment. As an example, images from a color motion picture film are picked up by a passive ...

Drinking glasses are washed in a device having a brush assembly which is slidably mounted on a vertical post extending upwardly from a supporting base. A spring normally urges the brush assembly in an upper position. A link has its opposite ends swiveled respectively to said base and to said brush assembly to cause said assembly to turn about the axis of said post when a glass is inserted in said assembly and pressed downwardly towards said base.

An adjustable cable rack includes an elongated bracket adapted to support one or more rack arms at various levels and a connector adapted to rigidly secure the bracket to a continuous channel shaped support. The connector has a brace member which prevents pivotal movement of the bracket about the support and screw threaded holding means inter-connecting the brace, bracket and support which permits adjustment of the cable rack.

A pull tab for a pressurized container which can be manually removed to release the fluid under pressure and which also operates as a relief valve if the internal pressure in the container exceeds a desired level. The tab is formed in place by placing a piece of heat-recoverable plastic tubing or rod in one or more appropriately sized holes in the container and then expanded by heat to block the hole. The plastic tubing or rod then acts as a valve which relieves the container pressure upon its r...

In anodizing aluminum the primary power source is three phase which is converted into six phase and each current in each of such six phases flowing through an anodizing bath is controlled as to intensity and form with a large positive pulse followed by a smaller negative pulse and with the rate of such pulses being adjustable within the range of one to twenty per second for control of shade of the anodized aluminum.

A heat recoverable closure article and a method for covering a conduit junction having at least three arms. The article comprises a radially heat-shrinkable tubular member, or a member in sheet form having its opposite edge regions held together to form the tubular member. The member includes a heat-shrinkable aperture with a surrounding wall, the wall being such that, on heating, its height and periphery are reduced.

A cleaning device for cauterizing knives presterilized for single surgical use and including a supporting frame adapted to be attached to a towel or drape used in surgery and held by an atraumatic clip also used in surgery, the frame containing a pair of abrasive strips having mutually engaging surfaces provided with diverging entrance ends, between which a cauterizing knife may be inserted to scrape cauterized flesh therefrom. In one embodiment, the supporting frame containing the abrasive stri...
