Abstract: A N K L E    S U P P O R T              ABSTRACT OF THE DISCLOSURE     An ankle support having a main body portion to extend about the Achilles' tendon of a foot and along the inner and outer sides of that foot with a tongue portion and overlapping first strap portion passing across the ankle to completely encircle the ankle of a wearer and having a stirrup portion depending from the main body portion to pass beneath the arch and sole of the foot leaving the heel and toes exposed is disclosed.    The main body portion, first strap portion and tongue are formed as different regions within a single sheet of multi-layer fabric with the stirrup portion being formed from a separate piece of the same multi-layer fabric and joined by stitching to the main body portion in two regions along one edge thereof.     A pair of side stiffening members are sandwiched between main body portion layers to reduce sidewise flexing of the ankle joint.   Optionally, a second strap portion may be formed integral with and tightening from the main body portion adjacent the tongue for tightening the support about an ankle above the region of the first strap portion with the two straps encircling the ankle in opposed senses.    The straps are fastener to the main body or tongue portion employing contact fastener material such as Velcro.

Abstract: ABSTRACT             The invention relates to a leaky cable intrusion detection system comprising a pair of spaced, parallel, buried, leaky coaxical cables.  A radio frequency signal is applied to one of the cables, whereby an electromagnetic field outside said one cable is established, and a radio frequency signal from the field penetrates and is received from the other of the cables whereby disturbances in said field can be detected.  The cables are spaced apart a distance such that they are intermediately coupled, being coupled to a greater degree than loosely coupled and to a lesser degree than tightly coupled.  In the preferred embodiment a longitudinal shield is spaced from and is below the cables.  By varying the spacing between the cables and the shield, variations in field shape and sensitivity of the system can be substantially reduced.

Abstract: Electric Propulsion System for Traction Vehicles with Automatic Retard Speed Regulation Abstract of the Disclosure Two separately-excited d-c electric motors are used to drive the wheels of a traction vehicle.  The magnitude of motor field current varies as a function of the value of a variable control signal, which value is representative of any deviation of the field current magnitude from a given reference magnitude.  When electric braking of the vehicle is desired, the reference magnitude is normally determined by the difference (if any) between the actual rotational speed of the slower motor and a predetermined desired speed, whereby motor field current is varied as necessary to regulate the retard speed of the vehicle.  Means is provided for automatically initiating the retard speed regulation mode of operation as the vehicle accelerates and the actual rotational speed of the faster motor approaches the aforesaid desired speed.

Abstract: ABSTRACT      A substantially flat lid of thermoplastic material for a liquid pack has an endless line of weakness defining a pouring opening which is disposed inwardly of an outer first plane of the lid.  An opening flap portion closes the pouring opening and is mounted to a hinge.  A handle is secured to the opening flap portion.  The opening flap portion is connected through a collar portion which projects outwardly from the endless line of weakness to a main wall of the lid.  A collar is disposed at the periphery of the lid at an inwardly displaced position, for mounting to a side wall of the pack.  The line of weakness extends in a second inner plane at a spacing (a) from and parallel to the outer first plane and thus spacing (a) between the two planes is greater than or equal to the height (H) of the collar portion which projects outwardly from the weakening line.  This has the advantage that the whole of the outside contour of the lid can be within the outer first plane, so that the pack has good standing and stacking abilities, and occupies less space in transportation.

Abstract: ABSTRACT OF THE DISCLOSURE           A scarifier tooth assembly of the type used on earth excavation equipment for digging furrows in the ground which comprises a replacement point and a clamp member for securing the point to a conventional tapered and grooved shank carried by the bucket of the earth excavating equipment.          The point is of a forged integral construction and includes a tapered forward digging portion and a shaft portion extending rearwardly therefrom.  The shaft portion defines a flat lower bearing surface adapted to abut a flat bearing surface on the shank and a curvilinear upper bearing surface adapted to abut an interior curvilinear bearing surface of the clamp member.          Ear members project laterally from the rearward most end of the shaft portion of the point and fit about the shank for prevent-ing relative lateral movement between the point and shank.  The clamp member is generally of an inverted "U"-shaped configura-tion and defines an inner curvilinear bearing surface and inwardly projecting lateral flanges at the open end thereof.          Upon slighting the clamp over the point and shank, the projecting flanges fit within the locking grooves in the shank while the curvilinear bearing surface presses against the upper mating bearing surface on the shaft portion of the point, wedging and securing the point tightly between the clamp and shank.

Abstract: Abstract A spray cooling system for cooling a furnace for the melting or treatment of molten metal, and particularly the roof and/or sidewall of electric-arc, plasma-arc and ladle furnaces.  Other types of metal treating furnaces and accessory equipment may also be cooled with the system of the invention.  In the invention, spray headers and pipes (14, 16, 18) supply coolant to spray nozzles (70) distributed within a coolant space in a roof structure (10) to spray coolant against the working plates (22) of the roof.  The spray pipes and headers also comprise part of the framework for the roof, resulting in a simple, lightweight, one-piece structure.  A pump (56) is connected to evacuate the coolant from the coolant space, and thermocouples (58) are embedded in the working plates to monitor their temperature and operate controls to adjust the flow rate so that only the amount of coolant necessary to maintain a desired temperature is supplied to the roof.  The sprays of coolant produce many small droplets which provide a large surface area for more effective cooling, and at least a substantial portion of the droplets are vaporized during cooling whereby the latent heat of vaporization of the coolant is utilized to provide a significantly increased cooling rate.          Similar arrangements may be used to cool the delta and/or sidewall of the furnace.   The method of cooling a furnace by directing sprays of coolant against the working plates is also disclosed.
