Abstract: Abstract of the Disclosure There is disclosed a unitary cabling element for optical fibers, consisting of an elongated strip member of a resi-lient plastic material having a continuous bottom face and a series of spaced parallel recesses opening into the opposite face of the strip member by means of longitudinal channels of a substantially trapezoidal shape, the mating faces of which diverge outwardly with an included angle of 360°/n, n being the number of the recesses in the strip member. Optical fibers are loosely received within said recesses and the strip member is wound around an elongated central carrier in the configuration of a unitary cylindrical cable element with angularly spaced closed recesses therein. Said unitary cable elements may be juxtaposed in a bundle or concen-trically wound to form a high density optical fiber calbe. The cabling element may have an internal flat configuration or at least a partially cylindrical configuration.

Abstract: FLEXIBLE SHEET MATERIAL ROLL DISPENSING    ABSTRACT     Dispensing flexible sheet material involves mounting at least one roll R on dispensing arm means 48 pivotally connected at 54 to a dispenser 12 near the lower end of the chassis so that as material on the roll is depleted the concomitant diminishing diameter roll R will swing down on the dispensing arm means 48 for the roll axis to move through an arc spaced from the axis of the feed roller 24 to wedge the roll surface firmly against the surface of a feed roller as the axis of the roll R moves toward a line extending through the feed roller axis and the pivotal axis where the dispensing arm means 48 is connected to the chassis. When the roll R is essentially depleted it swings past the line and the feed roller 24 into a discard area 60. Dispensing from multiple rolls in succession utilizes an initial roll R mounted as above described and a reserve arm means 66 connected to the chassis through means 76 which permits the reserve arm means 66 to move down vertically relative to the chassis as the initial roll R is depleted to a lower position where the reserve arm means 66 thereupon pivots relative to the chassis and the reserve roll RR engages with the feed roller 24 when the essentially depleted initial roll R swings into the discard area 60 to swing through an arc similar to that which the initial roll R moved through as its diameter diminished.

Abstract: ABSTRACT The invention relates to an ultrasonic array having the transducer elements arranged in lines and columns, the transducer elements being joined on both sides to opposing contact surfaces and switches being associated both with the contacts of the one contact surface and also with the contacts of the other contact surface, which switches serve to set preselectable emitting and/or receiving surfaces consisting of transducer elements during one emitting/ receiving cycle, more particularly for the purpose of dynamic focusing.  The aim of the invention is to construct an ultrasonic array which requires only optimally low expenditure for switches and which, in this way, also allows the change-over, if required, to continuously varied aperture.  This aim is achieved according to the invention by joining the transducer elements in groups with their one contact surface in the direction of the lines and with their other contact surface in the direction of columns and by associating at the most one single common line group switch with each line group and at the most one single common column group switch with each column group.  It is easily possible to change to continuously variable aperture when continuously alterable switching elements, such as controllable resistances or the like, are used as emitting and/or receiving switches.

Abstract: ABSTRACT OF THE DISCLOSURE:           Crude oil and gas production wells, which no longer produce oil or gas utilizing conventional primary and secondary means of recovery, can be returned to production by treatment comprising addition of an aqueous solution of alkyl or aralkyl polyoxyalkylene phosphate ester surfactants follow-ed by successive treatment with a hydrocarbon.  Increased production also can be obtained in low-producing oil and gas wells by similar treatment with certain phosphate ester surfactants.  Subsequent to treatment of a producer oil or gas well, said phosphate ester surfactant is forced into the formation utilizing a hydrocarbon or water in the case of a gas well and said surfactant and hydrocarbon or water mixture is allowed to remain in the producing well, for an effective period of time ranging from not less than 24 hours to one month.  Thereafter, pumping and/or conventional fluid drive means are then utilized to recover oil or gas from the sub-terranean oil or gas formation.  The amount of aqueous surfactant solution and hydrocarbon or water utilized are sufficient to permeate the oil or gas subterranian formation in the area immediately adjacent to the producing well bore and up to a radius therefrom of about 20 feet.  The process of the invention provides for the use of an aqueous solution of a phosphate ester rather than an oil-external or water-external micellar dispersion in the stimulation of oil and gas wells.

Abstract: Abstract A terraced substrate laser is improved by forming a stripe-shaped impurity diffused current-injection region from a cap layer as to an oblique lasing region of the underlying active layer, so that a corner part of the current injection region at least touches the lasing region.  The current injection efficiency of the lasing region is thus greatly improved and the injected current is effectively limited to the oblique lasing region even when A large current is injected.  Furthermore, the threshold current can be greatly reduced.  This laser can perform a stable fundamental transverse mode oscillation even during high power operation.
