Cartridge Loading Apparatus.
Patent for a new and improved cartridge loader. This design "consists of a filling attachment to cartridge-loading blocks, which is composed of a hopper part having discharge-tubes in the bottom and a perforated and spring-actuated slide-piece having perforations registering with said tubes, and of a lower part having upwardly-extending tubes sliding on the bottom tubes of the hopper and downwardly-extending tubes of conical shape . . . and are opened or closed by a second spring-actuated slide-piece" (lines 16-26).

Balanced Piston Engine.
Patent for a new and improved balanced-piston engine. This design "relates to that class of steam or other engines which are constructed with two pistons receiving the pressure in opposite directions, each connected with cranks set at opposite positions, whereby the strain occurs simultaneously in opposite directions upon the crank-shaft and balances the same within its bearings, and thus obviates great friction on the journals and thereby economizes power" (lines 7-15).

Coffee Roaster.
Patent for a new and improved coffee roaster. This design calls for "a revolving cylinder; and the invention consists of a cylinder provided with a hollow trunnion, and of a semi-tubular tester introduced through said trunnion into the cylinder, which tester serves as a handle for revolving the cylinder, and can be withdrawn from time to time with samples of coffee to enable the operator to judge of the progress of the roasting process" (lines 11-19).

Child's Crib.
Patent for a new and improved child's crib. This design utilizes "a rock-shaft with inward-projecting arms, from the inner ends of which the cords are suspended, [and it] avoid[s] the friction and wear of the cords incident to the carrying of these through the screw-eyes, as shown in [a previous patent], making them last much longer, beside simplifying the construction of the crib" (lines 67-74).

Car-Coupling.
Patent for a simple, practical, and reliable car-coupling with a side latch. It is "adapted for automatic connection in pairs, when two cars having the improvements are brought together on the same track, which will be capable of a ready release from the side of either coupled car, and also that will be adapted by its peculiar formation to receive support from one part of the improvements, when a coupled drawhead is partly detached from its connections to the car, and which if not so sustained might fall on the track, derail the car having the disabled coupling, and occasion the wreckage of said car and others of a train" (lines 14-27).

Churn.
Patent for an automatic churn, which is an improvement to a previous churn, no. 39,532. It has a two-part cabinet, the top part equipped with a hinged top, a crank shaft, ratchet-wheel, spring pawl, and a tubular square pocket at the end of the crank-shaft. The square pocket is where one can attach a handle to operate the churn. The lower half of the cabinet opens on the side and contains the container, dasher-rod, and churn-dashers.

Cavity resonance absorption in ultra-high bandwidth CRT deflection structure
An improved ultra-high bandwidth helical coil deflection structure for a cathode ray tube is described comprising a first metal member having a bore therein, the metal walls of which form a first ground plane; a second metal member coaxially mounted in the bore of the first metal member and forming a second ground plane; a helical deflection coil coaxially mounted within the bore between the two ground planes; and a resistive load disposed in one end of the bore and electrically connected to the first and second ground planes, the resistive load having an impedance substantially equal to the characteristic impedance of the coaxial line formed by the two coaxial ground planes to inhibit cavity resonance in the structure within the ultra-high bandwidth of operation. Preferably, the resistive load comprises a carbon film on a surface of an end plug in one end of the bore.

Microwave Sintering of Nanophase Ceramics Without Concomitant Grain Growth
A method of sintering nanocrystalline material is disclosed wherein the nanocrystalline material is microwaved to heat the material to a temperature less than about 70% of the melting point of the nanocrystalline material expressed in degrees K. This method produces sintered nanocrystalline material having a density greater than about 95% of theoretical and an average grain size not more than about 3 times the average grain size of the nanocrystalline material before sintering. Rutile TiO{sub 2} as well as various other ceramics have been prepared. Grain growth of as little as 1.67 times has resulted with densities of about 90% of theoretical.

Reflection mass spectrometry technique for monitoring and controlling composition during molecular beam epitaxy
This invention is comprised of a method for on-line accurate monitoring and precise control of molecular beam epitaxial growth of Groups III-III-V or Groups III-V-V layers in an advanced semiconductor device incorporates reflection mass spectrometry. The reflection mass spectrometry is responsive to intentional perturbations in molecular fluxes incident on a substrate by accurately measuring the molecular fluxes reflected from the substrate. The reflected flux is extremely sensitive to the state of the growing surface and the measurements obtained enable control of newly forming surfaces that are dynamically changing as a result of growth.

Catalysts for Conversion of Methane to Higher Hydrocarbons
Catalysts for converting methane to higher hydrocarbons such as ethane and ethylene in the presence of oxygen at temperatures in the range of about 700 to 900{degrees}C are described. These catalysts comprise calcium oxide or gadolinium oxide respectively promoted with about 0.025--0.4 mole and about 0.1--0.7 mole sodium pyrophosphate. A preferred reaction temperature in a range of about 800 to 850{degrees}C with a preferred oxygen-to-methane ratio of about 2:1 provides an essentially constant C{sub 2} hydrocarbon yield in the range of about 12 to 19 percent over a period of time greater than about 20 hours.
