Abstract: RIG TRANSPORT             Abstract of the Disclosure A mobile jack-up drilling rig for offshore use is uni-quely designed to greatly reduce the weight of the entire assembly by using a light, openwork body or superstructure thereby eliminating the requirement that the rig be seaworthy and either partially or totally eliminating the requirement that the rig be bouyant. The jack-up rig requires assistance to be carried to the drill site. The system includes a truss design with little or no hull, using structural shapes for a superstructure whose size are dependant on weights and spans. The superstructure is supported by cylindrical, trussed, or other suitably shaped legs. Preload pods, which may be of any shape such as round, may be provided at each of the legs to attach to the superstructure. The preload pods, preferably, support the jacks used to raise and lower the legs. A minimum amount of drilling and support equipment, housings, and machinery is usually located on the rig to further lower weight and to make the rig small and light for transporting to the drilling site. The rig may be designed for tender assistance, the tender housing such equipment as drill pipe, mud pumps, and providing quarters. The machinery located on the rig may include the drill works, such as, for example, the draw works and rotary. For transportation purposes, the rig will be placed on a carrying vessel, for example, on a tender. When the rig arrives at the drilling site, it may be jacked up off of the carrying vessel by its legs or may be jacked up almost off the tender by its legs and preloaded using the carrying vessel before being jacked to its final position.  A curved skid rail may also be incorporated for azimuthally positioning the drill works to drill several wells.  The rig, because of its light weight, may be con-verted to a production rig after drilling operations have been completed.

Abstract: Abstract of the Disclosure A control system including apparatus for the trans-mission of information for the control of vehicles travelling in one direction on a guideway. The guideway is broken down into a plurality of groups of uniquely identified se-quential blocks. Each block has at least one vehicle detector for detecting the presence of a vehicle and having an operated condition responsive to vehicle detection. Each block further includes a transmitter for providing, to a vehicle within the block, information concerning the block it is in as well as information regarding the indentity of the next downstream occupied or unavailable block. To this end, each block has associated with it a word generator for producing a signal identifying the block; the word generator is coupled to the block transmitter, which transmitter is only enabled when the vehicle detector is in its operated condition. A communication channel extends in a direction opposite to the direction of travel on the guideway, and each block includes a coupler for coupling the portion of the communication channel co-extensive with the block to the adjacent upstream block. The coupler is responsive to the condition of the vehicle detector for maintaining a connection between the communication channel in the block with the communication channel of the next upstream block, when the vehicle detector is not operated. When the vehicle detector is operated, the coupler connects the output of the word generator to the next upstream block. The transmitter of each block receives another input from the communication channel. In this fashion, a vehicle in any block receives a signal indentifying the next downstream occupied block as well as a signal indentifying the block it is in.      For further refining vehicle control, a vehicle may also transmit to the wayside its position or position and speed, within a block, and this information can be trans-mitted on the communication channel to a next adjacent upstream vehicle in a similar fashion.

Abstract: ABSTRACT          A process of making cellulated glass beads by forming a mixture comprising glass particles and cellulating agent into nodules, heat treating the nodules to cause fusion of glass and evolution of gas from the cellulating agent to form cellulated glass beads, and cooling the cellulated glass beads to a rigid condition.  The cellulating agent utilized has the characteristic of creating expansion forces due to the evolution of gas during heat treatment which are generated wholly or mainly while the glass viscosity is within the range 106.5 to 108.5 poises.  The heat treatment is carried out with a quantity of cellulating agent at a maximum cellulation temperature which is not above the temperature corresponding with a glass viscosity of 105.5 poises and for a time such that the beads immediately following the heat treatment are populated with cells, and after cooling have a bulk density of not more than 0.5g/cm3 and a water-permeability of less than 15% by volume determined by measuring the volume of water absorbed by the cellulated glass beads when immersed in water at room temperature for a period of 24 hours.

Abstract: A B S T R A C T     A bumping and jarring tool for a well drill string is provided having a telescoping housing and mandrel with an annular hydraulic chamber therebetween divided into two portions.  The lower portion is exposed to the ambient hydrostatic well pressure and the upper portion varies in volume as the tool opens and closes.          When the tool is opened a jar is produced by a valve between the chamber portions which restricts hydraulic fluid flow between the chamber portions resulting in a pressure drop in the upper portion and by a pressure increasing element in the lower portion which increases the pressure therein while the pressure drops in the up-per portion.  When the valve permits unrestricted flow again, the sudden return to pressure equilibrium produces the jar stroke.

Abstract: HYDRAULIC MASTER-SLAVE STEERING SYSTEM FOR A WIDE TRACK VEHICLE     ABSTRACT OF THE DISCLOSURE       An electro-hydraulic steering system is disclosed for a wide track steerable vehicle which changes the position of each steerable slave wheel to an optimum angle Control means, including electro-hydraulic steering means, are provided to cause the steerable slave wheels to turn relative to one another to assume and maintain an optimum turning  radius and optimum turning relationship as the vehicle operator maneuvers the vehicle along a desired curved path of travel by hydraulically controlling a master steerable wheel.  The system minimizes tire wear, reduces structural stresses in the vehicle, and maximizes traction during turning maneuvers.          No conventional tie rods are required and the system may be implemented to permit two wheel steering, four wheel crab steering, and four or more wheel coordinated steering.  The system uses a position sensor on a single hydraulically steered master wheel to produce a signal to control the posi-tioning of the slave wheels.  The signal is digitized to produce a signal which, when compared to a position signal from a position sensor for each slave wheel, causes each slave wheel to assume an optimum position which is about perpendicular to the turning radius of the vehicle.
