Abstract: ABSTRACT OF THE DISCLOSURE:    A baby carriage having a pair of front legs and a pair of rear legs.  The pair of rear legs each have an angle bar pivotally connected thereto while the angle bar has a pusher rod body pivotally connected to the other end thereof.  With the baby carriage in the opened state, the angle bar is substantially in line with the associated pusher rod body.          With the baby carriage in the closed state, the pusher bar body and the associated angle bar are in bent relation to each other, thus reducing the vertical dimension of the baby carriage.  Further, in response to the turning movement of the angle bars relative to the rear legs, both the longitudinal and the transverse spacings between the front and rear legs are reduced.  In this manner, the baby carriage is folded.

Abstract: ABSTRACT OF THE DISCLOSURE     A boiler liner intended for improvement of combustion, reduction of smoke loss, and procurement of heat flow in existing oil- or gas-fired central heating boilers, through which the supplied heat energy is better utilized, by way of heat resistant material to upwardly confine the flame room as compared with an existing larger boiler chamber.  The liner flame limi-tations are made from a highly insulating material which will cause the assimilated heat to be stored at temperatures almost equalling the flame temperature, resulting in the stored volume of heat being quickly given off by radiation after the flame has been extin-guished, undesirable heat convection in the boiler chamber will fail to manifest and counterradiation from the highly insulated material will prolong the interval between the sparks.

Abstract: ABSTRACT           Aqueous xanthan gums normally crosslink at a pH greater than about 1.5 in the presence of ferric ions.  This phenomenon is undesirable under many conditions of use, such as acidizing treatments of wells, and is inhibited or prevented by adding certain soluble alkanoic and/or alkenoic acids to the system.  The alkanoic and alkenoic acids have at least 4 carbon atoms and bear at least 2 alcoholic hydroxyl groups per molecule and can be added as the organic acid per se or as a soluble salt or .gamma.-lactone.  Ascorbic acid and erythorbic acid are examples.

Abstract: ABSTRACT     Disclosed is a digital frequency divider which operates faster than prior art dividers by reducing the propagation time of the feedback loop.  The divider comprises three counters and a switching control means.  A first coun-ter selects one out of first and second frequency division factors in response to a first control signal to thereby divide an input signal frequency.  The second counter frequency divides the output of the first counter by a third frequency division factor.  The third counter frequency divides the output of the first counter by a fourth frequency division factor which is smaller than the third frequency division factor.  The switching control means converts the output of the third counter into a signal synchronized with the output of the first counter and supplies the converted signal to the first counter as the first control signal.  Also disclosed is a frequency synthesizer using the dig-ital frequency divider.

Abstract: ABSTRACT OF THE DISCLOSURE             Method and apparatus for forming a stator for a dynamoelectric machine by inserting prewound coils into a slotted stator core in-cludes enlarging the slot openings or gap between certain adjacent pairs of stator, teeth, placing the prewound stator windings in se-lected stator core slots and thereafter reducing the slot opening or gap between those certain adjacent pairs of teeth.  The disclo-sure apparatus includes a stator bore support and a series of punches to be placed in stator slots and collapsed radially in-wardly to bend the stator teeth tips to conform to the bore sup-port.  An otherwise conventional coil inserting or injecting machine has unique accepting the respective formed stator teeth tips, and a pair of ribs outside the depression for spanning the corresponding tooth.  Reforming of the stator teeth so as to provide a cylindri-cal bore stator may be accomplished by a plurality of cylindrical rollers which simultaneously engage the stator bore and traverse that bore interior surface to displace the stator teeth tips ra-dially outwardly, thereby providing a wound stator for further processing having a substantially reduced iron gap or for a given iron gap containing windings of a larger wire size than normally insertable in a stator having that iron gap.  The slot openings may be enlarged either by mechanical forming of the stator tooth tips or the stator laminations may be initially stamped with this deformation so that the stator core or stack of such laminations need not be mechanically formed to increase the iron gap available for the wire insertion process.

Abstract: EX SITU AND IN SITU SEPARATION OF         BITUMEN FROM BITUMEN-BEARING SUBSTRATE                        Abstract Bitumen is separated from water-bearing tar sands by solvent extraction techniques employing solvents having an inverse critical solution point. Preferred solvents include the secondary and tertiary amines such as diisopropylamine and triethylamine. The amine is admixed with the tar sands to dissolve the bitumen. The resulting mixture of solvent and bitumen is then separated from the tar sand solids. The bitumen is separated from the solvent and water by thermal distillation techniques. The solvent and water are condensed, placed in a decanter, and raised to a temperature above the critical solution temperature of the solvent, at which temperature the two liquid phases, a solvent phase and a water phase, are formed. The solvent is decanted and recycled to the head of the process to be remixed with fresh tar sands. The water fraction is further treated to assure that all residual solvent has been removed and is then returned to the environment.

Abstract: Abstract of the Disclosure A ring laser gyroscope has at least two of its mirrors vibrated perpendicular to their reflective surfaces by equal and opposite amounts to maintain the total beam path length constant.  The amplitude of vibration causes the beams to be shifted across surfaces of all of the mirrors by a distance that is at least close to a Bessel zero distance so as to reduce the intensity of back scattered radiation at the main wavelength to a value close to zero.  For an equilateral triangular ring laser gyroscope, two of the mirrors are vibrated between about 0.66.lambda. and 0.74.lambda. , optimally about 0.71.lambda. .  for an isosceles tri-angle having vibrating mirrors at two vertexes having angles of about 51.65°, the magnitude of vibration should be about 0.91.lambda..

Abstract: A METHOD OF DETERMINING RESIDUAL OIL SATURATION            Abstract In a method of determining the residual oil saturation of an oil bearing formation 26, a borehole in the formation 26 is traversed with a gravimetric logging tool 10 to measure the earth's gravity at spaced locations in the borehole.  The gravitational gradient of the formation 26 is then determined by comparison of the measurements of the earth's gravity at successive locations, whereafter the formation bulk density is calculated from the variation in the  gravitational gradient at the successively spaced locations and from the vertical distance between the successive spaced locations.  From measurements of the matrix density, water density, oil density, and fractional porosity of the formation, the calculated formation bulk density can be used to determine the residual oil saturation of the formation 26.
