Abstract: ABSTRACT OF TIE DISCLOSURE The optical cable having an outer jacket and a plurality of optical transmission elements and auxiliary elements for receiving tensile loading, each of said optical transmission elements containing one or more fiber optical waveguides characterized by the optical transmission elements and auxiliary elements being stranded together around a central core with an alternating direction of twist, and a thin intermediate layer holding the elements in their place at a point of separation but allowing unstranding of the elements once the auxiliary elements are subjected to a longitudinal pull.  Thus, the stranding of both the optical transmission elements as well as the auxiliary elements can be cancelled over a limited length for each element to produce an excess length for each of the elements.

Abstract: ABSTRACT OF THE DISCLOSURE Hydraulic cements such as Portland cement are interground with amine salts of aromatic group-containing carboxylic acids (e.g. triethanolamine benzoate) to enhance the efficiency of the grinding operation.  In a preferred embodiment, a mixture of aromatic group-containing carboxylic acids obtained as a low cost by-product in a commercial process to produce phthalic anhydride, is utilized to prepare the amine salt grinding aid of the invention.  The grinding aids of the invention also appear to inhibit the "pack-set" tendencies of the resulting ground cement particles.

Abstract: PORTABLE CONSTRUCTION HEATING SYSTEM:          ABSTRACT.       A portable construction heating system is described in which flexible heat elements are placed in close proximity to objects of various shapes and configurations which would otherwise be difficult to heat.   The heating elements are comprised of flexible hoses which contain a circulating preheated liquid. The primary object of this invention is to provide an improved method of applying heat to fresh concrete which has been placed in pre-constructed formwork during extreme cold weather.  The advantage is that heat can be applied to virtually any shape of formwork including structural beams, walls, vertical columns and slabs, and together with the application of a tight fitting insulating cover provides an economical means of preventing damage due to freezing during the curing process.          Conventional heating methods utilize direct fired forced air heaters which are placed inside of temporarily constructed hoardings or enclosures.   Due to the nature of open flame heaters the enclosures must be large and therefore are costly to construct and uneconomical to heat.  The temporarily constructed enclosures offer little resistance to wind damage, and are obviously a fire hazard.  The heat is generally too great at the source and too little at the far end of the enclosure. Conventional heaters produce carbon monoxide fumes which attack the concrete curing process rendering this equipment undesirable without heat exchange fitments added.

Abstract: Abstract Stroke Control for Press A method and apparatus for controlling the stroke of a press in which the movements of two portions of a movable platen of the press are continuously sensed during a stroke.  A signal is generated whose magnitude at any time during a stroke is dependent on the sum of the distances moved by the two portions of the movable platen during the stroke.  The signal is compared with a preselected value which is selected in accordance with the length of the stroke required and the stroke is terminated when the magnitude of the signal equals the preselected value.

Abstract: Abstract A composite lining material is a thermoplastics sheet (e.g. polypropylene) bonded to one face of a non-wogen web of fibres (e.g. polyester) through which continuous filaments (e.g. polyester) are stitched, e.g. in chain or tricot stitch.  A reinforcing layer, e.g. of fibre-reinforced resin, is applied to the other face of the web to provide a lined wall structure which may be the wall of a lined pipe, vessel or tank.      The continuous filaments are bonded to the lining and reinforcement layers at multiple, spaced locations and provide a direct, mechanical link between those layers in addition to reinforcing the fibrous web.  Shear strengths of greater than 100 kg/cm2 and steady peel strengths of greater than 7.0 kg/cm are obtainable, and there is good retention of these properties at elevated temperatures.

Abstract: Abstract The roots of human hairs of a patient are devitalized using high intensity, short duration pulses of light having wave-lengths with respect to which the skin of the patient is non-absorbative and the hair of the patient is relatively absorbative. A narrow, focused beam of the light is aimed at the epidermis of the patient adjacent the hair such that an extension of the beam intersects the hair root at an angle relative to the skin surface.  A short pulse passes through the skin and is absorbed in the hair root, destroying its blood supply.  Apparatus for practicing the method employs a manually controlled two-axis positioning system supporting the focusing system that is con-nected to a laser light source by a flexible fiber optic bundle. A shutter selectively positionable in the optical path allows a low intensity beam to be produced for aiming and the shutter is removed from the optical path for the pulse period to produce the high energy beam.

Abstract: DIFFERENTIAL DETECTOR FOR DEMODULATING FM OR PM SIGNALS                   ABSTRACT      A differential detector is disclosed that is used in FM or PM receivers for demodulating a modulated carrier signal. The detector uses a mixer/phase detector for combining an intermediate frequency phase modulated or frequency modulated signal with the same signal delayed to demodulate the signal.          Delay inherrent in an IF filter of the receiver having the detector is utilized for this purpose. The undelayed and delayed signals required for operation of my differential detector are obtained from the input and output respectively of the IF filter. The output from my detector has spurious signals not typically present in the output of prior art differential detectors but these spurious signals are removed by a filter including low pass, band reject and/or notch filtering to yield only the modulating signal.
