Describes the use of lamb and mutton in meals, and methods for slaughtering, butchering, and preparing it. Discusses the reasons for its limited use.

The construction of giant airplanes was begun in Germany in August, 1914. The tables annexed here show that a large number of airplanes weighing up to 15.5 tons were constructed and tested in Germany during the War, and it is certain that no other country turned out airplanes of this weight nor in such large numbers. An examination of the tables shows that by the end of the War all the manufacturers had arrived at a well-defined type, namely an airplane of about 12 tons with four engines of 260 horsepower each. The aircraft listed here are discussed with regard to useful weight and aerodynamic qualities.

Given here is a description of the design of a scientific recording wind tunnel balance. It was decided that the most satisfactory arrangement would be a rigid ring completely surrounding the tunnel or wind stream, so that the model could be supported from it by wires or any arrangement of spindles. The forces and moments acting on this ring can then be recorded by suitable weighing apparatus. The methods available for recording forces on the arms are explained. The proposed type of balance will support the model rigidly in a variety of ways, will make a complete test without attention, and will plot the results so that all computations are avoided.

Described here is a method by which high average fuel economy has been achieved in aircraft engines. Details are given of the design of certain foreign engines that employ an unusual type of fuel-air ratio control in which the change in power produced by a mixture change is due almost entirely to the change in the power producing ability of the unit weight of the mixture. The safety and performance features of this type of control are explained.

Technical notes discussing the steadiness factor in engines and the calculations that can be used to arrive at it. Factors affecting the steadiness factor are detailed, including the mass of parts, torque, engine rotation, and power.

Fan brakes used as absorption dynamometers in testing internal combustion engines have the disadvantage that a given fan will run only at one speed when the engine is delivering full power. In order to be able to vary the speed at which a given power will be absorbed, English manufacturers have for some time been using a cylindrical housing around the fan with one or two variable openings in the periphery. Here, results are given of tests conducted to determine how great a range of speed can be obtained from such a device.

With the advent of the V type engine, a new method to measure the clearance volume in cylinders was needed. It was suggested that this measurement could be made by a process which consisted essentially of simultaneously changing both a known and unknown volume of gas by a known amount and then calculating the magnitude of the unknown from the resulting difference in pressure between the two. An instrument based on this design is described.

Patent for a hospital bed. Provide a bed with separate adjustment support for the sick or people with a disability.

Patent for a combustion apparatus that will maximize the heat produced with any given amount of fuel.

Patent for a tire mold that improves the viability of a tire mold due to the adjustable levers used during the tire curing process.

Patent for a composing machine utilizing the general principles of the linotype and similar composing and typecasting machines. It is used to provide a more compact machine of that general character for commercial use.

Patent for a cost-effective device that can remove and exterminate parasites from cotton as it's being harvested without damaging the cotton itself, including illustrations.

Patent for "new and useful Improvements in Valves" (lines 5-6) used in pneumatic inner tubes to stop leakage, including illustrations.

Patent for a water heating attachment for internal combustion motors that will allow the cooling fluid in said motors to remain heated even when the motor is at rest, especially during freezing temperatures, including illustration.

Patent for tractor coupling. The object of the invention is to provide a coupling for tractor and plow. When a plow hits an obstruction, the coupling will automatically disengage tractor and plow without breaking any parts.

Patent for new ventilated body-garments "known as union-oversuits or "unionalls"" (lines 15-16) which improves the shoulder coverings and open armpit areas, allowing the passage of air but covering the area from rain.

Patent for hullers for removing hulls of shells for seeds or other similar products. The invention "is of especial utility in hullers for cottons seeds." However, it is noted that a cotton seed huller is only one adaptation of the invention.

Patent for a method of sealing oil wells to avoid applying casing to the wells to prevent leakage, seepage, or cave-ins.

Patent for a toy grasshopper that is able to jump on surfaces once it is set down to simulate the propelled jumping of a grasshopper. Because of its design, primarily of rubber bands and levers, the movement is unique. It is also able to be formed into other animals or insects, as the body is made of wood.

Patent for improvements of the threading apparatus for pipes through a simple attachment to automobiles wheels. Illustrated figures with descriptions are presented to easily show the ways in which the device attaches and is used.

Patent for an engine designed for combustion of kerosene with air. The patent notes improvements for regulating the mixture ratios and maximizing efficiency by heating the air intake.

Patent for a tire core with interlocking sections that can be removed easily from built tires to reuse, including illustrations.

Patent for improved ties and fastenings for securing and binding together railway rails.

Patent for a surgical splint, which is semi-rigid so that the instrument is rigid enough to maintain its shape and tension, but with a construction that includes softer materials like rubber so that it can be adjusted without causing pain or discomfort. Patent includes illustrations.
