Patent for improved check values in relation to a boiler of locomotives, to better secure priming and increase forcing power of its injector.

Patent for a liquid indicator to determine if the supply of oil has been depleted in the crank case of an automobile's internal combustion engine. Further purposes of this patent include the closing of an electrical circuit when the oil in the crank case becomes low in order to sound an audible noise that alerts the driver that more oil is needed. The patent intends to make the invention durable, easy to use, and inexpensive to manufacture.

Patent for a simplified internal combustion engine that is lighter and more efficient than previous models. It also features detachable and removable parts that will decrease time and cost of repairs, includes illustrations.

Patent for a stalk puller that can pull the stalk from the ground and chop in pieces for feeding for fertilizer.

Patent for a laminated fabric for tire casings that reinforces motor vehicle tires to reduce heat exposure and risk of damage. This type of laminated fabric is intended to resist wear and prevent tire blow-outs.

Patent for a tail-end light for automobiles, subway and surface trains, and other motor propelled vehicles which changes color to indicate the speed at which the conveyance is traveling.

Patent for udder protectors for milch (dairy) cows. To keep foreign matters from contact and to keep the udders warm for the animals' comfort, including illustrations.

Patent for a plant chopper that can chop down plants of the row variety while not disturbing others that are spaced apart. It can also be an attachment to a cultivator.

Patent for an improved mowing device for the removal of weeds and grass, specifically from railways.

Patent for a device for unscrewing and withdrawing pipe from wells, mines, or other similar uses. This tool is attached at the end of a drill stem and threaded in the ordinary right hand direction to unscrew and withdraw.

A control system for thermoelectric refrigerators is disclosed. The thermoelectric refrigerator includes at least one thermoelectric element that undergoes a first order change at a predetermined critical temperature. The element functions as a thermoelectric refrigerator element above the critical temperature but discontinuously ceases to function as a thermoelectric refrigerator element below the critical temperature. One example of such an arrangement includes thermoelectric refrigerator elements which are superconductors. The transition temperature of one of the superconductor elements is selected as the temperature control point of the refrigerator. When the refrigerator attempts to cool below the point, the metals become superconductors losing their ability to perform as a thermoelectric refrigerator. An extremely accurate, first-order control is realized.

The present invention is directed to a rapid nondestructive method for determining the extent of strain hardening in an article of tungsten-nickel-iron alloy. The method comprises saturating the article with a magnetic field from a permanent magnet, measuring the magnetic flux emanating from the article, comparing the measurements of the magnetic flux emanating from the article with measured magnetic fluxes from similarly shaped standards of the alloy with known amounts of strain hardening to determine the hardness.

A secondary electrochemical cell is described with the positive and negative electrodes separated by a molten salt electrolyte with the negative electrode comprising a particulate mixture of lithium-aluminum alloy and electrolyte and an additive selected from graphitized carbon, Raney iron or mixtures thereof. The lithium-aluminum alloy is present in the range of from about 45 to about 80% by volume of the negative electrode, and the electrolyte is present in an amount not less than about 10% by volume of the negative electrode. The additive of graphitized carbon is present in the range of from about 1 to about 10% by volume of the negative electrode, and the Raney iron additive is present in the range of from about 3 to about 10% by volume of the negative electrode.

A frequency-spectrum analyzer with phase-lock for analyzing the frequency and amplitude of an input signal is comprised of a voltage controlled oscillator (VCO) which is driven by a ramp generator, and a phase error detector circuit. The phase error detector circuit measures the difference in phase between the VCO and the input signal, and drives the VCO locking it in phase momentarily with the input signal. The input signal and the output of the VCO are fed into a correlator which transfers the input signal to a frequency domain, while providing an accurate absolute amplitude measurement of each frequency component of the input signal.

Patent for a new End-Gate Fastener, accompanied by several illustrations of form and function. Specific claims to the End-Gate Fastener include: transverse rods designed to mount device for easy removable and replacement of device on wagons, transverse rods designed for sliding to connect rods inside a wagon or door, associated rods which can be used to restrict outward movement of rods in the fastener when placed under tensions, and the combination of the wagon body with the end gate once the fastener as been installed.

Patent for the improvement of "the construction of spring trips, and to provide a simple and inexpensive spring trip, capable of being constructed of sufficient strength to enable it to be employed on stirring and breaking plows as well as cultivators, planters and the lighter class of agricultural implements" (lines 12-18) including instructions and illustrations.

Patent for improved combined railway rail supports and joints that increases the efficiency and utility of such devices. Eliminates the need of employing additional bolts or other fastening means.

Patent for an improved plow foot that allows for the easy installation or removal of the plow foot, secured connection of the plow foot, and improved regulation of the angle of the plow foot.

Patent for a new sliding jaw type wrench which enables objects to be clamped in the jaws of the wrench securely while leverage is used to rotate the head of a nut.

Patent for improved construction and function of wrenches. Improvements include a more simple, durable, and inexpensive method of construction and arrangement of the adjustable jaw as to allow a single hand to hold and adjust the wrench simultaneously.

Patent for an ink well that can be closed with a non-sticking closure when not in use to avoid "evaporation of the ink" (lines 14-15) and includes illustrations.

Patent for an insect and worm destroyer that is secured to the frame of a gang or cultivator and both cultivates and exterminates insects, worms, and the like as it moves down each row of plants.

Patent for a wheel for vehicles that has springs within the rim which compress when placed under a load or jolted.

Patent for new stamping device for "quickly and accurately stamping railroad tickets on their faces with the date of issue, the destination and the time limit or number of the train on which the ticket is to be used" (lines 11-15) including instructions and illustrations.
