Abstract: ABSTRACT OF THE DISCLOSURE           Four sealed-beam headlamps are mounted in paired relationship on the front Or the vehicle and energized in various combinations to provide a low-beam, a mid-beam and a high-beam lighting mode each Or which have a light dis-tribution pattern which provides improved illumination of the roadway under various driving and traffic conditions with a minimum of glare.  One lamp in each pair Or headlamps contains dual filaments, one of which is used in the low-beam lighting mode and the other of which is used in the high-beam lighting mode.  The remaining lamp in each pair contains a single light source and one of these lamps has a dual-segment reflector and serves as a mid-beam lamp.  The other single-light-source lamp constitutes a high-beam head-lamp.

Abstract: DEFECT COMPENSATION SYSTEMS                    Abstract of Disclosure In a video disc player, an FM signal recovered from the disc is subject to frequency demodulation to obtain a composite color video signal.  In the composite signal, chrominance information appears in the form of a modulated subcarrier buried in spectrum troughs in the midband of a wider band luminance signal.  The composite signal is applied to a modulator to develop amplitude modulated carrier waves, which serve as the "normal" signal input to a 1H delay line.  Comb filter circuits respond to the delay line input and output to obtain separated chrominance and luminance signal components, which are suitably processed for delivery to color image display apparatus (e.g., color television receiver).  The amplitude modulated carrier wave output of the delay line is also utilized as a "substitution" signal input to the delay line, replacing the "normal" signal input when a defect det-ector, monitoring the output of the FM demodulator, indicates the onset of a picture defect.  The "substitution" signal path includes a network providing respectively different amounts of phase shift at the carrier frequency, and at the sideband frequency associated with the color subcarrier.  In a variant of the aforesaid arrangement, switching between "normal" and "substitution" signals is effected in the video domain.  A composite signal from the output of the FM demodul-ator is normally supplied to the amplitude modulator input, but, upon defect detection, a detected version of the amplitude modulated carrier wave output of the delay line is substituted.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method for treating wells completed in subterranean formations which contain unconsolidated sand particles, so as to form a permeable barrier which will permit the flow of liquids therethrough while restraining the flow of the unconsolidated sand particles into the well bore.  The method comprises saturating sand adjacent the well bore to be treated with petroleum having a high asphaltic content and optionally thereafter contacting the asphaltic petroleum with a solvent capable of solubilizing non-asphaltic fractions of the petroleum and precipitating or causing deposition of the asphal-tic or bituminous portions of the petroleum.  A heated fluid such as steam is thereafter injected into the formation to cause solidification of the asphaltic materials which effectively binds the sand grains together to form a porous mass which will effectively restrain the movement of sand particles in the well bore upon subsequently placing the well on production.  Suitable hydrocarbon materials for causing precipitation of the asphaltic or bituminous portions of the petroleum include liquid paraffinic hydrocarbons such as butane, pentane, or hexane, N-methyl-2-pyrrolidone and furfurel.  Steam or a mixture of steam and non-condensable gas such as nitrogen, or mixture of steam and air are then injected into the formation to dehydrate and otherwise solidify the precipitated asphaltic material.

Abstract: This specification discloses a leakage reactance transformer for supplying electric arc welding current and comprising a core formed from a stack of laminations having a central 'key-hole' shaped opening punched therein and defining an arcuate core portion and two spaced legs.  The core has primary and secondary windings mounted thereon and a keeper secured to the legs to close the flux path of the core.  One of the windings is mounted on a frame which is pivoted relative to the core so that the winding is movable along the arcuate core section towards and away from the other winding.  A magnetic shunt member is also mounted on the frame approximately 180.degree. from the movable winding and in one position bridges the gap between the legs of the core and in another position is remote from this gap.  In the bridging position the shunt contributes to the leakage reactance of the transformer and in the remote position contributes substantially no leakage reactance.  The shunt is formed from a sector of the portion of the laminations cut from the core to define the arcuate section of the opening and the keeper is formed from the remainder of the portion cut from the core and defining the space between the legs of the core.  The core and windings are mounted within a casing and means are provided to facilitate the pivotal movement of the movable winding and shunt to any position between the two extremes whereby the welding current may be infinitely varied between the values at the extremes. In a modification two similar cores are connected together by their legs and a movable winding and shunt member is mounted on each.  In this arrangement the output current range is increased.

Abstract: ABSTRACT OF THE DISCLOSURE           Outer wrap for pipelines is made of essentially flat thermoplastic fibers preferably woven in a basket weave pattern with from about 15 to 20 per cent of the fabric area being open.           On wrapping a pipe freshly coated with coal tar or equivalent material, the wrap does not tent to sink into the coating as is found to be the case with other outer wraps, such as those made from round glass fibers.  Because of the ability of the mesh wrap of this invention to eliminate air entrapment during the wrapping operation, an essentially holiday-free coating results.       This system also lends itself to uniform distribution of cath-odic current over the entire surface.  The tough, smooth wrap-ping does not allow cold flow of coating material through the fabric due to the weight of backfill and tension of the wrap.

Abstract: TITLE IMPROVED BRAKE MECHANISM       ABSTRACT OF THE DISCLOSURE         A brake mechanism is mounted on a vehicle and includes a housing having a slot for receiving a rotatable disc to be braked.  The upper portion of the housing includes a chamber for receiving pressurized fluid from a source.  A spring actuated piston is slidably and sealingly disposed within the chamber.  A removable spring assembly is positioned forwardly of the actuating piston and exerts a preselected spring force thereon. When the fluid pressure acting against the piston is less than the spring force applied to the piston, the piston moves axially in the chamber and a rod portion thereof contacts a lever that is pivotally mounted to the housing.  The lever pivots on the housing to axially displace a brake applicator piston that is movably positioned in the housing adjacent to the rotatable disc. A plurality of braking pads are secured to the end portion of the applicator piston and additional braking pads are secured to the brake housing opposite the disc.  Displacement of the applicator piston moves the braking pads into braking engagement with the disc to overcome rotation of the disc and stop the vehicle.  In the event fluid pressure in the chamber diminishes, the spring assembly is automatically actuated to exert a parking brake force and move the braking pads into braking engagement with the disc.  The spring assembly may be locked in a compressed state for efficient removal from the housing for maintenance or replacement and includes a device for visually indicating the wear condition of the braking pads.
