Abstract: ABSTRACT             A self-deploying ice probe and ice anchor which can be used to anchor instruments or objects to an iceberg, or to attach a hawer which can be used to tow the iceberg.  In its simplest form, the invention is an ice probe comprising a structure having a heat retaining elongated body, an ice penetrating end of which is heat exuding.  Preferably the body is smooth walled, the body retaining heat by having a high thermal conductivity core which is insulated around its walls and one end.  The heat exuding end touches the ice, and melts a hole, the elongated body slipping into the hole as it melts.  Once all of the heat energy retained in the core has been dissipated, the body freezes into position.  A cable attached to the insulated end can be used to attach a load. According to another embodiment of the invention, an ice anchor is comprised of an ice probe, the probe comprising a structure having a heat retaining elongated body, one end of which is heat exuding, the anchor further comprising a frame for supporting the ice probe in a position with the heat exuding end in contact with the ice, whereby a hole can be melted into the ice.  The anchor includes apparatus for facilitating passage of the probe into the hole as the hole is melted.  A cable for applying load is fastened to the frame whereby tension can be applied to the frame along an axis different from the axis of the probe.  The probe passes into the melted hole in the ice only to a position whereby it is still retained by the frame.  Therefore the force applied to the frame is transmitted to the probe, and then to the ice. Preferably the frame retains a plurality of such probes which pass into the ice in different directions.  The anchor has been found to have an extremely high load bearing capacity.

Abstract: ABSTRACT         The present invention relates to the replacement of an existing main, particularly an existing cast iron gas main with a new main utilizing a device in the form of a mole.  In accordance with the improvement described herein the mole includes a pivotally mounted blade at its forward end and other blades which are fixed.  The mole is driven through the existing main by means of a numerically actuated hammer engaged percussively with an internal wall of the mole formed by an internal bore. The pivotal blade pivots under the action of an associated piston which is hydraulically actuated by fluid supplied from a hose by way of a channel.  The blade is normally closed but is pivoted to fracture any circumferentially located obstruction located in the main and serving to inhibit the movement of the mole therethrough.

Abstract: ABSTRACT OF THE DISCLOSURE     A friction stay arm for a hinged window sash in a window frame has a sliding member with a friction surface to lock the window sash in any open position.  By utilizing a sliding member with a friction surface to lock against a metal track, the force required to lock the window is reduced and the holding power preventing the window swinging in a wind is increased.  The stay arm assembly includes a locking handle in the window sash having a sliding position and a locked position, extension arm mechanism connected from the handle, channel shaped track in one side of the window sash having a fixed ramp member therein, a movable ramp member positioned in the track and connected to the extension arm mechanism such that when the handle is turned from the sliding position to the locked position, the movable ramp member moves adjacent the fixed ramp member in the track.  A sliding member in the track is free to slide when the handle is in the sliding position, and locked by the movable ramp member when the handle is in the locked position, an arm member has one end pivotally attached to the sliding member and the other end pivotally attached to a fixed position on the window frame.  The improvement comprises inward facing shoulders at extremities of flanges on the channel shaped track, the sliding member having a friction surface to engage with the inward facing shoulders of the track when the handle is in the locked position, the friction surface being forced against the inward facing shoulders of the track by the movable ramp member and the fixed ramp member.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for selectively diffusing impurities such as zinc into the substrate of a compound semiconductor such as gallium arsenide (GaAs).  The method makes use of a diffusion mask in such a manner that the thickness of the oxygen-containing layer at the interface between the diffusion mask and the semiconductor substrate is less than 20 .ANG. so that the abnormal transverse diffusion that would otherwise occur at the interface in the vicinity of the opening of the diffusion mask on the semiconductor surface is suppressed.  The result is an increased accuracy in the diffusion pattern of the impurities.

Each alignment system includes three vibrating conveyor stages which prealign the articles and feed such articles into an alignment container where they are aligned so that their longitudinal axes are substantially parallel in such container.  The plurality of alignment systems are carried on a common support which is intermittently rotated about an axis of rotation to move the input conveyor stage into a load position beneath the output gate of the common collector container for loading.  After 360 degrees rotation such alignment system is moved into an unload position where the weighed batch of aligned articles are discharged from the alignment container as a batch through a transfer tube into a packaging machine for packaging such aligned batch of articles.

Abstract: ABSTRACT        A fuse for an alternating current power circuit in the medium volatage (3.3 kV to 38 kV) range.  The fuse comprises a sealed chamber and a first electrode is mounted within the chamber, the first electrode having a substantially circular periphery and being electrically connected to a first terminal to which a first conductor may be connected.  A second electrode is arranged with a conductive surface internally of the chamber, the conductive surface being spaced from the first electrode.  A coil is connected in an electrical path between the second electrode and a second terminal to which a second conductor may be connected.  An additional electrical contact is mounted within the chamber and in direct electrical connection with the second terminal, and a fusible element directly electrically connects the first electrode and the additional electrical contact.  An electronegative halogenated medium fills free space within the chamber.  The normal current path between the first and second terminals and through the fuse is by way of the first electrode, the fusible element and the additional electrical contact.  The arrangement is such that when the fusible element breaks, the resulting fault current forms an arc between the first electrode and the additional contact, one root of the arc subsequently commutates from the additional contact to the second electrode, the fault current flows through the coil and induces a magnetic field, the magnetic field causes the car to rotate around the first electrode in the electronegative medium, and the arc is thereby extinguished, so interrupting the fault current.

Abstract: NETWORK ROUTING ARRANGEMENT            Abstract Circular paths in a multinode connection are avoided by passing an adaptive routing state, from node to node, which specifies the path options that the current node may use in its selection of a next step in the connection.  The routing state, which is characterized by, for example, a single digit, is updated by the current node and is a function of the recent path history of the connection.  The single-digit routing state controls the advancement of the connection by specifying whether the next selected step can be either a forward step, a null step or a backward step, or any combination thereof.  A forward step advances the connection toward its destination, a null step does not advance the connection and a backward step causes the connection to step backward to a node not yet in the connected path.  When a node selects a next step, it adapts the routing state digit to reflect its selection and passes the new routing state digit to the next node.
