Abstract: ABSTRACT OF THE DISCLOSURE A rotary engine having a plurality of impel-lers pivotally mounted within respective chambers around a rotor.  The rotor is mount-ed in a stator which has at least one pair of oppositely positioned chambers between which chambers inner surfaces of the stator define an outer cam profile, inlet and exhaust ports being provided in each stator chamber.  The outer cam profile causes the impellers to move inwardly of the rotor into the rotor chambers to compress air blown into the stator between the compression face of an impeller and the out-er cam profile.  A fixed cam causes the impel-lers to move outwardly of the rotor into the stator chambers during the firing, exhaust and induction stages, whilst fuel is injected into the compressed air above one impeller prior to the preceding impeller opening, such that the resultant explosion acts against a rear face of the preceding impeller as it opens to pro-vide the firing or power stroke of the engine.          The outer cam profile is such as to retain each impeller closed after ignition of its charge, until a preceding impeller has moved towards the completion of its firing stroke.

Abstract: INSTRUMENT FOR MEASURING HARMONIC DISTORTION IN TELEPHONE TRANSMISSION                 Abstract of the Disclosure There is disclosed an instrument for measuring and displaying the harmonic distortion introduced during telephone line transmission.  A frequency phase lock circuit is employed to generate disturbance-free in-phase and qua-drature signals of a received test tone, the disturbance-free generated tones being different from the transmitted test tone as a result of possible frequency shift along the transmission channel and phase shifts in the terminal equipment at both ends.  The frequency of each of the in-phase and qua-drature signals is multiplied by the harmonic factor of in-terest (e.g., two).  Each of the frequency-multiplied signals is then multiplied by the received test tone, and the two resultant signals, after low-pass filtering, are applied to the vertical and horizontal deflection plates of an oscillo-scope to form a display of the type disclosed in my U.S. Patent 3,906,173 (September 16, 1975.   The display, in addition to reflecting a measurement of the frequency shift along the channel, also provides separate indications of the degree of harmonic distortion which occurs both ahead of the frequency shift (in the send terminal) and after the frequency shift (in the receive terminal).

Abstract: ABSTRACT OF THE DISCLOSURE            In a method for the manufacture of twistless yarn, a sliver or a roving which consists of a fibrous material containing at least two components, at least one which being a potential adhesive, is drafted in a wet condition to a thinner fibrous sliver. After false twisting and the supply of additional moisture, the fibrous sliver is bonded.        The bonding process is realised by activation of the potentially adhesive component and drying of the fibrous sliver. After the application of additional moisture the fibrous sliver is passed through a narrow space and heated, giving rise to evaporation of a small amount of moisture in the fibrous sliver and a rapid saturation of moisture in said narrow space, such that the potentially adhesive component is sufficiently activated by the residual moisture in the fibrous sliver.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is a process for recovering solvent vapor which comprises absorbing solvent vapor in a first absorbing liquid, and subsequently stripping the sol-vent vapor to regenerate the first absorbing liquid.  The stripped solvent vapor may be reabsorbed in a second absorb-ing liquid.  The second absorbing liquid may be under greater than atmospheric pressure.  Regenerating the first absorbing liquid may occur at pressures only slightly below atmospheric pressure, i.e., a low vacuum, by recycling the absorbing liquid to a regenerator.  Because the regenerating process does not require the use of a high vacuum, the gas recovery apparatus may be more economically constructed and operated.
