  • Patent number: 4509612
    Abstract: Disclosed is a latch mechanism for a tilt-cab truck including a latch pin and a latch locking assembly adapted to engage the latch pin. The latch locking assembly includes a housing, a sliding latch assembly disposed in the housing for sliding movement in a direction generally perpendicular to the motion of the latch pin, a spring which biases the sliding latch assembly into engagement with the latch pin, a hydraulically actuated piston which forces the sliding latch assembly out of engagement with the latch pin, and a latch locking member which releasably holds the sliding latch assembly out of engagement with the latch pin.

  • Patent number: 4506751
    Abstract: Disclosed is a tilt cab truck having a shock absorber assembly in which a path of fluid communication between the fluid reservoir and the interior of the shock absorber assembly is automatically blocked both when the brake is applied and when a roll-angle sensing device senses a roll angle greater than a predetermined value, thereby strengthening the shock absorbing function. Two embodiments of the invention are disclosed.

  • Patent number: 4506631
    Abstract: The invention describes a process wherein high-purity hydrogen and oxygen gases can be economically produced via a water electrolysis method, utilizing cheap energy recovered from an incineration process of industrial, municipal, agricultural and other waste materials in a fluidized-bed incinerator. In the said process combustible solid and/or liquid wastes with high energy content are exploited to supply the energy required to incinerate and decompose other solid or liquid wastes with lower or no energy content. Also the process provides a method wherein any solid, liquid or gaseous emissions or effluents from the process are effectively trapped, controlled and converted to environmentally acceptable, inert and harmless products. Also the process includes an energy recovery system such that the thermal energy from the incineration is used to produce steam and generate electricity required for all operations in the process including the production of oxygen.

  • Patent number: 4502673
    Abstract: Disclosed is a tilt cab suspension system comprising integral shock absorber and air spring assemblies located between the truck frame and the cab. The shock absorber assembly comprises a hydraulic circuit which provides for circulation of hydraulic fluid during an upstroke and/or downstroke of a piston within a cylinder. A selectively adjustable control valve is located in the hydraulic circuit and may be regulated by the vehicle operator to control the stiffness of the shock absorber sub-assembly and, consequently, the hardness of the ride.

  • Patent number: 4501568
    Abstract: A shuttle wheel toy comprising a rotary wheel having a magnetized rotation shaft extending through a central portion of the wheel to have ends protruded beyond side walls of the wheel and mounted across a pair of substantially parallel arranged rails secured at one end respectively thereof in a grip, which may be gripped by a hand to axially sway the rails to thereby let the rotary wheel rotate and run on the rails which provide for a path of reciprocation to the wheel. Through a battery housed in the grip and the rails functioning as a positive and a negative electrodes, an illumination element housed in the rotary wheel can be energized to light.

  • Patent number: 4496174
    Abstract: An insulated drill collar gap sub assembly for a toroidal coupled telemetry system including a first annular sub member (150) operable to be connected at one end to a drill collar and a second annular sub member (156) operable to form a part of a drill collar sub. The first and second annular sub members have interconnecting structural members (54, 58) operable to structurally interfere. The interconnecting structural members are dimensioned to form a continuous gap (160) between mutually opposing surfaces and a dielectric material (162) fills the gap to electrically isolate the first annular sub member with respect to the second annular sub member. A bearing member (164) is positioned between the first annular member and the second annular member and is coated with a dielectric insulation (166) to facilitate the formation of a drill collar gap sub assembly of structural and electrical integrity.

  • Patent number: 4487052
    Abstract: A device for removing irregularities in or enlarging a buried duct comprises a cylindrical housing (10) corresponding approximately in diameter to the required diameter of the duct, a plurality of tapered leaf members (14) pivotally attached at their rear ends to the front of the housing, and a conical wedge (18) driven by an axial hydraulic ram (12) mounted inside the housing (10). In operation, the apparatus is drawn through the duct with the leaf members (14) in a retracted position in which they form a tapered nose portion, until an irregularity in the duct causes resistance to forward movement. The ram (12) is operated to force the leaf members outwardly against the wall of the duct to remove the irregularity. The leaf members (14) are then retracted as the apparatus is drawn forward to the next obstruction. The apparatus is particularly intended for preparing damaged sewers prior to fitting an inner, lining pipe.
