Apparatus for Retailing Shot.

Patent for a new and improved round dispenser. This design "consists in a receptacle or multiple bin the several compartments of which are provided with valves controlling exit-openings, whereby any desired quantity of shot, descending by gravity from the appropriate compartment, may be directed into the scale-pan of a scale without the necessity of lifting the receptacle or bin or any part of its contents" (lines 35-43).

Blacking Brush. (open access)

Blacking Brush.

Patent for a new and improved blacking brush. This design utilizes springs to move a blacking brush to and from a can of polish. This results in "evenness of wear of the bristles of the brush, economy of blacking, absence of spattering while extracting the blacking from the box, convenience in substituting the circular brush as a lid for the box in case of loss of the box-lid, and the saving of time in looking for a blacking-brush and a blacking-box separately" (lines 53-60).

Process to Accomplish Autothermal or Steam Reforming Via a Reciprocating Compression Device (open access)

Process to Accomplish Autothermal or Steam Reforming Via a Reciprocating Compression Device

The invention provides a method and apparatus for producing a synthesis gas from a variety of hydrocarbons. The apparatus (device) consists of a semi-batch, non-constant volume reactor to generate a synthesis gas. While the apparatus feeds mixtures of air, steam, and hydrocarbons into a cylinder where work is performed on the fluid by a piston to adiabatically raise its temperature without heat transfer from an external source.

Beam position monitor (open access)

Beam position monitor

An apparatus for determining the position of an x-ray beam relative to a desired beam axis where the apparatus is positioned along the beam path so that a thin metal foil target intersects the x-ray beam generating fluorescent radiation. A PIN diode array is positioned so that a portion of the fluorescent radiation is intercepted by the array resulting in a series of electrical signals from the PIN diodes making up the array. The signals are then analyzed and the position of the x-ray beam is determined relative to the desired beam path.

Cryogenic Homogenization and Sampling of Heterogeneous Multi-Phase Feedstock (open access)

Cryogenic Homogenization and Sampling of Heterogeneous Multi-Phase Feedstock

An apparatus and process for producing a homogeneous analytical sample from a heterogeneous feedstock by: providing the mixed feedstock, reducing the temperature of the feedstock to a temperature below a critical temperature, reducing the size of the feedstock components, blending the reduced size feedstock to form a homogeneous mixture; and obtaining a representative sample of the homogeneous mixture. The size reduction and blending steps are performed at temperatures below the critical temperature in order to retain organic compounds in the form of solvents, oils, or liquids that may be adsorbed onto or absorbed into the solid components of the mixture, while also improving the efficiency of the size reduction. Preferably, the critical temperature is less than 77K (-196 C). Further, with the process of this invention the representative sample maybe maintained below the critical temperature until being analyzed.

A Raman Fiber Optic Probe Assembly for use in Hostile Environments (open access)

A Raman Fiber Optic Probe Assembly for use in Hostile Environments

This invention provides a device for Raman spectroscopic measurement of composition and concentrations in a hostile environment by the use of a first fiber optic as a means of directing high intensity monochromatic light from a laser to the hostile environment and a second fiber optic to receive the lower intensity scattered light for transmittal to a monochromator for analysis. To avoid damage to the fiber optics, they are protected from the hostile environment. A preferred embodiment of the Raman fiber optic probe is able to obtain Raman spectra of corrosive gases and solutions at temperatures to 600 F and pressures up to 2000 psi. The incident exciting fiber optic cable makes an angle of substantially 90{degree} with the collecting fiber optic cable. This 90{degree} geometry minimizes the Rayleigh scattering signal picked up by the collecting fiber, because the intensity of Rayleigh scattering is lowest in the direction perpendicular to the beam path of the exciting light and therefore a 90{degree} scattering geometry optimizes the signal to noise ratio.
