Abstract: TROLL RESTRICTING METHOD AND APPARATUS                       ABSTRACT      The invention is a toll restricting method and apparatus which restricts toll telephone calls from telephone stations by interrupting dialing sequences if from the station there is dialed (a) a restricted digit during a first pre-determined number of digits, or (b) more than a second pre-determined number of digits.  Restricted dialing sequences are interrupted by disconnecting the telephone from the central office line for a period sufficient to release all the registered digits and to return central office dial tone to the telephone.  Also provided are a method and apparatus for allowing absorb digits to be dialed before the counting of digits begins.  A method and apparatus are additionally provided for restricting a telephone from which delays between digits dialed are greater than a predetermined time delay.

Abstract: INSULATING TINSEL CONDUCTORS Abstract of the Disclosure An insulation comprising a polyether polyester thermoplastic copolymer obtained by reacting 1, 4 butane diol terephthalate with terepthalate esters of polytetra-methylene glycol is coated over an irregularly configured conductor, such as for example, a tinsel conductor, suitable for use in telecommunications cordage by moving the copolymer through an extruder and along a flow path formed between a core tube and wall of a die cavity. The die cavity adjacent to the throat of the die has a frustoconical portion formed . with an approach angle of sufficient magnitude to minimize the pressure drop through the extruder to extrude the co-polymer at a temperature slightly above the melting point of the copolymer. The copolymer is tubed over the tinsel conductor with a gas at a controlled volume rate of flow being moved through the core tube with the tinsel conductor to expand the copolymer extrudate as it flows out of the die opening to cool the extrudate and to facilitate advantageously oriented crystalline growth of the copolymer. Subsequently, the insulation is drawn down about the tinsel conductor with a slight spacing therefrom while treating the insulation with water at a predetermined temperature to anneal the insulation in a predetermined manner.

Granted: 1981-02-10
Abstract: ABSTRACT OF THE DISCLOSURE     A method of incorporating additives into cross-linked poly-olefins is provided herein.  A shaped article formed of the cross-linked polyolefins is heated to an elevated temperature above its crystalline melting point.  That article at that elevated temperature is then con-tacted with the additive for a period sufficient to obtain the desired take up of additive per unit area of the surface contacted therewith.          The article is removed from contact with the additive while maintaining the article at the elevated temperature.  Thereafter the article is cooled to below the crystalline melting point.  The article so formed does not suffer the disadvantage of blister formation.  Moreover, the additive can supply surface friction reducing properties to make the material suitable for uses as ski soles and boat hulls.

Abstract: A B S T R A C T           A cableway carriage has a body by means of which the carriage can be suspended from and for movement along a support cable.  A drop arm depends from the body and carries a rotatable member with a surface which can be operatively engaged with a haul-in line whereby the member is rotated by pulling on the haul-in line.  The haul-in line is wound around the rotatable member and serves to hold a load suspended from the carriage.  A brake is positioned for braking the rotation of the member, and a mechanism carried by the drop arm is operatively connected to the brake whereby the member is braked in response to a tension above a predetermined value being applied to the haul-in line.  The mechanism includes a pivotable arm which forms part of the carriage and is connected to an operating linkage of a brake band wound around a brake drum connected for rotation in unison with the rotatable member in such a way that tension above a predeter-mined value on the haul-in line pivots the arm to tighten the brake band onto the brake drum.

Abstract: ABSTRACT OF THE DISCLOSURE             An enclosed container has a chamber in which a gaseous fluid is heated as by solar radiation and a first valve permits some of the fluid to be ejected as it expands during heating. The remaining fluid is then cooled as by clouds blocking the sun or during the night and a subatmospheric pressure is developed in the chamber. Through a second valve in the container this negative pressure is communicated to a siphon having an inlet immersed in liquid at an upper level and an outlet closed by a third valve at a lower level. The subatmospheric pressure causes the siphon to be filled with liquid and the weight of the liquid opens the third valve at the outlet causing the siphon to operate. the second valve prevents the loss of subatmospheric pressure in the siphon. The siphon may be used to automatically drain water from areas such as flat roofs of buildings.
