Abstract: Abstract of the Disclosure A cup dispensing package comprises an axially collapsible cylindrical sleeve for storing a stack of nested, disposable cups.  The sleeve comprises at least a pair of bands at its opposite end portions, axially extending, uniformly circumferentially spaces slits between the bands that define axially extending strips provided with circumferential cut scores, and detent means for one of the bands frictionally engaging the rim of a partially extending cup to retain the latter prior to its forcible removal.  The strips fold radially outwardly then downwardly about their cut scores and transverse sections thereof in response to axially applied compressive force on the sleeve, by the user, as the cups are removed, thereby presenting a fully extended frictionally retained cup for dispensing until such time the cup supply is exhausted.

Abstract: ABSTRACT OF THE DISCLOSURE      An ergometric exerciser of the constant work type using a mechanical to electrical transducer as its basis is described. The exerciser is controlled by a single chip microcomputer and associated electronic interfacing means to perform a multiplicity of selected functions.  For example, the ergometric exerciser provides:  adjustable work loading from 300 to 2100 kpm per minute; a flashing indicator light to warn of a low pedal speed; a pulse rate measurement from 40 to 200 beats per minute; a sonic pulse alert system adjustable from 60 to 200 beats per minute; an accurate electronic start/stop timer adjustable from 1:00 to 60: on minutes; and a microcomputer controlled work computer which accurately calculates work done to a maximum of 99,990 kpm.  All of the above functions can be conveniently perform-ed by virtue of a control panel and visual display which is very easy to use to accurately and efficiently perform the above functions.

Abstract: Apparatus for Controlling the Performance of a Motor Compressor Abstract A hermetically sealed motor compressor unit has refrigerant gas at discharge pressure substantially surrounding the motor of the unit.  The compressor includes at least two cylinders in which gas is compressed.  A suction plenum for receiving gas at suction pressure surrounds each of the cylinders.  Conduits, equal in number to the number of cylinders, are disposed externally of the compressor for delivering the gas into each of the plenums.  One end of the conduit is connected to the plenum and the other end of each conduit is interconnected with the remaining conduits.  The pressure pulsations developed in each conduit are controlled whereby the pressure in each plenum is at a maximum when the suction valve for a particular cylinder opens and is at a minimum when the piston is substantially at bottom dead center.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to a method and a device for determining the concentration of a substance, which is bound to particles in a flowing medium, which substance can prevail in  varying concentration.  The determination is carried out by light beams so selected, that the substance is absorbent for the radiation within a certain wavelength range, while the remainder of the particle material is reflecting.  By means of a detector the radiation is determined which passes straight through the flowing medium, and by means of a detector the radiation is determined which is scattered in a certain direction by the particles in the medium.  The concentration is calculated from the equation koncA =                 where Io is the intensity of the incident radiation, I1 is the intensity of incident radiation, Ir is the intensity of radiation which has passed straight through the medium, Is is the intensity of detected scattered radiation, k is a constant between ? and 1 depending on the detection angle for the scattered radiation, and A, c1, c2, c3 are constants.

Abstract: ABSTRACT       A three-stage process for gasification of a solid fuel to a product gas with a high heating value and low ni-trogen content by use of an iron-containing material.  The latter is first heated to a high temperature by hot combus-tion gases  and is then brought into contact with the solid fuel for the second stage.  The fuel is thus decomposed pyrolytically to a residue and a pyrolysis gas and the latter partially reduces the iron containing material.  Fin-ally, the residue and the iron containing material are oxi-dized by water or water vapour to produce product gas with simultaneous oxidation of the iron containing material.
