An improved process for solvent extraction of organic matter from shale by two extraction steps in sequence. The extraction steps are: (1) treating a kerogen-containing shale with a solvent system comprising a combination of water and an alcohol at a temperature of about 375 to 425/sup 0/C; and (2) treating the product of (1) with a solvent system comprising a combination of an alcohol and another organic solvent at an elevated temperature, but not above about 425/sup 0/C. The organic matter is recovered by separating the liquid which results from step (2) from the shale solids.

Patent for an improved automobile headlight function that allows the light to be pointed directly at the road in front of the wheels to avoid the glare/reflection associated with straight-forward lighting.

Patent for concrete blocks used for construction, including illustrations.

A method for reaction forming refractory metal carbides. The method involves the fabrication of a glassy carbon preform by casting an organic, resin-based liquid mixture into a mold and subsequently heat treating it in two steps, which cures and pyrolizes the resin resulting in a porous carbon preform. By varying the amounts of the constituents in the organic, resin-based liquid mixture, control over the density of the carbon preform is obtained. Control of the density and microstructure of the carbon preform allows for determination of the microstructure and properties of the refractory metal carbide material produced. The glassy carbon preform is placed on a bed of refractory metal or refractory metal--silicon alloy. The pieces are heated above the melting point of the metal or alloy. The molten metal wicks inside the porous carbon preform and reacts, forming the refractory metal carbide or refractory metal carbide plus a minor secondary phase.

A radiation dosimeter providing an indication of the dose of radiation to which the radiation sensor has been exposed. The dosimeter contains features enabling the monitoring and evaluating of radiological risks so that a user can concentrate on the task at hand. The dosimeter provides an audible alarm indication that a predetermined time period has elapsed, an audible alarm indication reminding the user to check the dosimeter indication periodically, an audible alarm indicating that a predetermined accumulated dose has been prematurely reached, and an audible alarm indication prior or to reaching the 3/4 scale point.

Patent for a new and improved coupling for railroad cars. This design consists in "[t]he combination . . . of the laterally and vertically movable draw-head having the hook at its outer end, the keeper depending from the lower side of the car, and in which the draw-head is confined, the spring connected to one side of the draw-head and bearing thereon, and the arm pivoted in a slot in the draw-head, and having the head projecting in rear of the lip or shoulder of the hook, and the lever fulcrumed to the end of the car and connected to the car" (lines 87-97).

Patent for an improved signal actuating mechanisms for railways. When the train cars reach an operating mechanism, a flag will be raised where pedestrians or cars cross, and cause a signal to be repeated until the train passes.

Patent for rotary well-drilling machinery where the "ring or bushing to rotate independently of the table and the present invention is directed to means for accomplishing the rotating effect." (line 24-27)

Patent for improvements in animal watering troughs that has an automatic float control valve in connection with the trough.

Patent for a tool "which is adapted for stretching wire for fencing purposed and which may also be used for drawing the staples from the posts and splicing between posts when such action is necessary." (Lines 9-13) Includes instructions and illustrations.

Patent for a life-saving device for the cabs of locomotives. The device is used to safely help the engineer or fireman escape from the locomotive engine cab should danger arise. The device is used to protect an individual against fire, hot water, or some other forms of danger.

Patent for a device held within the engineer's cab of a locomotive which the engineer can be enclosed in and dispatched from the engine safely in case of an emergency.
