Abstract: A combination red dot sight (reflex sight) and electronic range indicator displayed in a sighting element. The sighting element is housed in a body which includes lens elements and a light source for the red dot sight as well as an optical display for the range indicator. A processor for the red dot sight and the range indicator are housed in a frame. A user interface includes indicia for varying the intensity of the light source for the red dot sight as well as activate the range indicator. Alternately, the range indicator may be activated by a button positioned remotely, such as on the firearm or bow and may be wired to the range indicator circuit or communicate via wireless transmission. An emitting lens and a receiving lens are optically connected via a range finding circuit to the processor.

Abstract: An auger mixer for mixing a concrete mix includes an elongated mixer housing having a mixing chamber for mixing the concrete mix therein. A mixing auger is rotatably mounted within the mixing chamber. A bearing assembly mounts one end of the auger shaft to the mixer housing. A seal assembly comprising a stationary seal remains stationary relative to the mixer housing and a rotating seal rotates with the auger. The stationary seal and the rotating seal contact one another to create a seal preventing the concrete mix from exiting the mixing chamber and moving toward the bearing assembly.

Abstract: A damping system for an axle configured to pivot about a pivot point is provided. The damping system includes a first hydraulic cylinder having a first chamber and a second chamber and a second hydraulic cylinder having a third chamber and a fourth chamber. The first hydraulic cylinder is connected to the axle on one side of the pivot point and the second hydraulic cylinder is connected to the axle on the other side of the pivot point. A first fluid line connects the first chamber with the fourth chamber. A second fluid line connects the second chamber with the third chamber. A restricted fluid passageway connects the first fluid line and the second fluid line. A valve mechanism is disposed between the first fluid line and the second fluid line and is operable to release fluid from one of the first and second fluid lines when the pressure of the fluid in the one of the first and second fluid lines reaches a predetermined level.

Abstract: A torchable roll roofing membrane which comprises a reinforcing mat which is saturated and coated with bituminous composition comprising a bituminous component and, optionally, an unhydrogenated block copolymer of a monoalkenyl aromatic hydrocarbon and a conjugated diolefin, and coated onto one surface, a bituminous composition comprising a bituminous component and a hydrogenated block copolymer of a monalkenyl aromatic hydrocarbon and a conjugated diolefin.

Abstract: A weatherproof coating for roofs or decks is formed when an adhering material is used in conjunction with a nonwoven mat formed from a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.

Abstract: Metal amine complexes are formed from amines adhering to the general formulas ##STR1## by reaction with various metal salts. Prior to reaction with various metal salts, the above amines may first be reacted with a formaldehyde source or with a formaldehyde source followed by an epoxide or with an epoxide or with an epoxide followed by a formaldehyde source. The resultant metal amine complexes are then employed in asphalt compositions in order to increase the overall strength of such compositions.

Abstract: The physical properties of bitumen/aggregate compositions are improved bya. adding an antistripping agent selected from imidazolines, polyamines, alkoxylated polyamines, aminocarboxylic esters, amide-amines and mixtures thereof to a bituminous material;b. adding Portland cement to an aggregate; andc. blending the products of steps a. and b.

Abstract: Formaldehyde adducts of amines, polyamines and amides conforming to the general formula ##STR1## are employed in asphalt compositions in order to improve the overall adhesion between the asphalt and aggregate or glass fiber or glass fiber mesh and to thereby increase the tensile strength of the asphalt composition.

Abstract: In accordance with this invention there are provided compositions of matter comprising a bitumen containing material and an epoxylated polyamine wherein at least two of the amino nitrogen atoms are separated by six carbon atoms. These compositions provide improved adhesion between aggregate materials and the bitumen containing material.

Abstract: In accordance with this invention there are provided organic antimony stabilizer compositions effective in stabilizing halogen containing organic polymers against the deteriorative effects of heat comprising (1) at least one organic antimony compound having at least one antimony to sulfur to carbon (i.e. Sb-S-C) linkage, (2) elemental sulfur, and (3) at least one 2-mercaptocarboxylic acid. Said 2-mercaptocarboxylic acid and elemental sulfur also serve to provide hydrolytic and UV light stability to the antimony compound per se. Also provided are stabilized organic polymer compositions comprising a halogen containing polymer and said organic antimony stabilizer composition.

Abstract: A plurality of horizontally extending rows of alternately green and red signal lights are provided in a signal display grid in each of two respective traffic signal devices. Each traffic signal device includes a STOP-GO indicator and a street indicator positioned respectively at the top and the bottom of the grid. To the left and right of the grid in each traffic device are respectively positioned red and green vertical strip indicators. Stepping switch control circuitry actuates the aforementioned lighting elements such that the red and green lighting elements in the horizontally extending rows are alternately successively actuated to provide a traffic signal display consisting of a block of lighting elements moving in a downward direction within the grid. The STOP indicator and the red left vertical strip indicator are continuously lit during a "red-light" condition; and the GO indicator and the right vertical strip are continuously lit during a "green-light" condition.

Abstract: A traffic signal device, capable of being suspended from an overhead support, includes red colored and green colored lamps secured to an endless conveyor mounted about a pair of spaced sprocket wheels so as to effect movement of the lamps from the top to the bottom sprocket in the facing direction. The lamps are spaced on the conveyor so as to be sequentially exposed through an opening of a casing within which the sprockets and conveyor are mounted. Lighted amber traffic lamps are fixedly disposed at the top and bottom of the opening, and the red and green lamps are switched on and remain lighted only while moving downwardly. Stop and Go signs are likewise switched on and remain lighted while the respective red and green lamps are lighted. The motorist may therefore readily observe the time remaining for a llight change from green to red and from red to green.

Abstract: A bitumen composition comprising an asymmetric, radial polymer containing a plurality of block copolymer arms comprising at least one polymeric block of a monoalkenyl aromatic hydrocarbon and at least one polymeric block of a conjugated diolefin polymer and a plurality of conjugated diolefin polymer arms. The bitumen composition exhibits increased toughness and tenacity as determined by the Benson method and is particularly useful in road paving applications. Best results are achieved when the asymmetric, radial block copolymer is sulfur vulcanized after incorporation into the bitumen composition.
