Abstract: ABSTRACT OF THE DISCLOSURE     A  method  and  apparatus  for  forming  a  power transmission belt wherein an uncured belt sleeve is formed in situ on an expansible portion of a mandrel. The mandrel, with the belt sleeve provided thereon, is  disposed  coaxially  within  a  radially  inwardly grooved mold.  The uncured belt sleeve is urged rad-ially outwardly into the grooved surface of the mold by expansion of the mandrel and curing of the belt sleeve retained in association with the mold groove is effected to complete forming of the cured belt structure.  The cured belt structure is readily re-moved from the apparatus for further processing, such as for dividing the wide cured belt structure into individual multirib belts or individual V-belts, as desired.

Abstract: ABSTRACT OF THE DISCLOSURE :       Fabrics can be washed with a wash liquor to which has been added a detergent active material, a water-soluble carbonate material such as sodium carbonate and a carboxylic polymer such as hydrolysed polymaleic anhydride or a hydrolysed copolymer of maleic anhydride, ethyl acrylate and vinyl acetate.   The polymer reduces the level of inorganic deposition on the fabrics provided that the initial calcium/carbonate saturation ratio in the liquor is below about 50.   Thus the method is particularly suitable for use with water having a hardness below 20° FH, at product dosages below 5 g/1, and/or at temperatures below 60°C.   The saturation ratio may also be reduced by including a calcium sequestrant such as NTA in the composition.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus is provided for making a prevailing torque nut from a regular nut.  The regular nut is placed between two anvil members, and a gap between the anvil members is first decreased so that they contact the nut on opposite sides.  Then, the gap between the anvil members is further decreased by a preset amount, in order to permanently inwardly deform the nut.          By making the preset amount a constant quantity, a plurality of nuts having sightly different outside and inside dimensions can be consistently deformed.  A feature of this invention is the provision of a deformation apparatus which smoothly, progressively and consistently deforms a nut from one end to another.  To accomplish this, the anvil members which cause the deformation have oblique working surfaces which taper toward each other, and which are adapted to bear against the nut over substantially the whole of the length of the nut, with the exception of an integral washer if such is present.

Abstract: ABSTRACT OF THE DISCLOSURE         By measuring the power supplied to a compressor motor and by measuring four temperatures within a mechan-ical vapor-compression system, it is possible to develop a device for measuring and/or displaying the specific coefficient of performance of the mechanical vapor-compression system.  The use of the temperatures and power supplied to the compressor motor can be used with information on motor losses and a typical temperature-enthalpy and a typical pressure-entropy dia-gram to allow substantially instantaneous computation of the actual specific coefficient of performance of a mechanical vapor-compression system as it operates.  The measuring device can usually be installed totally exter-nal to a building in which the mechanical vapor-compression system is being used as a cooling sys-tem, or as a heat pump for heating and cooling.

Abstract: SLIDE CONNECTORS WITH LOCKING MEANS          Abstract This invention relates to the slide connectors with locking means for removably connecting two boards in L-connection or three boards in T-connection or four boards in Cross connection, which connection comp-rises a four-sided elongated member including four retaining slide grooves respectively included in four sides of the elongated member and a plura-lity of retaining slide rails rigidly affixed to the extremities of the boards, respectively, wherein the retaining slide rails slidably engaging the retaining slide grooves included in the elongated member are locked to the elongated member by a set screw threadedly engaging a hole central-ly disposed in one end of the elongated member, which set screw inter-feres with crest of the retaining slide rails.      Storage shelves such as book shelves are used in many homes.  The existing methods of constructing storage shelves are unsatisfactory to many users, especially those who live in the apartments or rented houses and have to move frequently, for the reason that the existing permanently assembled book shelves are not only bulky but also lack structural rigi-dity and, consequently, they are a nuisance in moving.  Furthermore, some times it is difficult to find the right spaces for the preassembled book shelves in many apartment buildings.  There do exist modular type and/or knock down type book shelves, however, such book shelves constructed per existing technology lack elegance and versatility in appearance and construction.      The primary object of the present invention is to provide the slide connectors with locking means that enables construction of a custom designed storage shelf system by using a set of standard components.      Another object of the present invention is to provide the slide connectors with locking means for constructing storage shelves which can be easily assembled and disassembled by the users.

Abstract: FREQUENCY MODUEATION-POLARIZATION SPECTROSCOPY             METHOD AND DEVICE FOR DETECTING                    SPECTRAL FEATURES                 Abstract of the Disclosure A method and device for detecting dichroic and/or birefringent narrow spectral features in a sample is described.  The method includes the steps of providing a beam of light having an optical frequency bandwidth which is narrow compared to the width of the narrow spectral feature and having a center frequency .omega.c which lies near the narrow spectral feature, polarization phase modulating a beam of light with a single RF frequency to provide a pure FM spectrum having upper and lower sidebands in which either the carrier and sidebands have been polarized differently with respect to one another, exposing the sample containing the narrow spectral feature to the polarized modulated light so that the FM sidebands probe the narrow spectral feature, polarization analyzing and then photodetecting the light emerging from the sample to detect a RF beat at the specific RF frequency used for the polarization phase modulation, and electronically monitoring the amplitude of the RF beat signal to indicate the strength of the narrow spectral feature.  The device includes a polarization phase modulator and a polarization analyzer positioned on opposite sides of the sample.  In a preferred embodiment the polarization phase modulator produces a frequency modulated optical spectrum with the sidebands polarized precisely orthogonal to the carrier.
