Abstract: There is described a self-propelled railroad track ballast broom machine having a first broom unit operatively mounted at the rear of the machine frame and a second broom unit operatively mounted at the front of the frame. The broom units have substantially cylindrical brooms extending transversely of the railroad track and deflector boxes located forwardly of each of the brooms.

Abstract: A method of producing pigskin comprises the steps of sequentially scalding the unprocessed pig carcass in a liquid bath at a temperature of substantially 57.degree. to 59.degree. C. for about 5.5 minutes, removing the carcass from the bath after scalding for 5.5 minutes therein, stripping the hide off the carcass, and singeing the hide.

Abstract: A heat exchanger for transferring heat from stale air evacuated from a building to incoming fresh air employs a core made of a stack of spaced aluminum sheets that are joined along opposite edges in an alternate arrangement to define two separate sets of air passages for the respective outgoing and incoming flows, while providing good thermal contact between the two flows. This contact is improved by generating a measure of turbulence in the air flows by forming the sheets with surface nodules. The core is mounted in a frame that can be readily slid into a housing containing fans for generating the air flows. In an alternative construction, each air flow can be caused to travel in series through two parts of each set of air passages, rather than in parallel. This series arrangement has the advantage of reducing the temperature drop across any one part of the core below the total temperature difference between the inside and outside of the building. A machine is also disclosed for manufacturing such a core.

After tub formation, further movement of the implanted ions is kept small by use of a high pressure process for growing the field oxide and by only limited further heating. Transistors are then formed in the tubs.

Abstract: The method of planarizing polysilicon-filled trenches involves first filling the trenches with an undoped polysilicon until the upper surface is substantially planar. The polycrystalline silicon is then heavily doped by means of diffusion of a dopant from the upper surface. The time and temperature of the diffusion are carefully controlled providing for the dopant to penetrate the polysilicon to a depth level with the tops of the trenches. A selective etchant is then utilized which removes the heavily doped polysilicon and leaves the undoped polysilicon untouched in the trenches.
