Abstract: This invention is directed to a frenum lock, also known as a natural expression former, for use by morticians. It relates to an improvement on two of my patents. I have a patent entitled "NATURAL EXPRESSION FORMER", U.S. Pat. No. 3,103,052, issuing date of Sept. 10, 1963 and a patent entitled "NATURAL EXPRESSION FORMER WITH BITE INDENTATION", U.S. Pat. No. 3,195,215, issuing date of July 20, 1965. The improvement of this invention is the positioning of the dividing lines in the central portion of the natural expression former or the frenum lock. The dividing lines in the central portion of the frenum lock permit wider spreading of the expression forming wing-like portions on insertion of the expression former into the mouth of the corpse or cadaver and permit greater adaptation of the expression former to the dental arch of the corpse or the cadaver.

Abstract: An airstream impinging laterally on a thread can convey a running thread through an opening. This "placing" of threads in nozzles fails at elevated thread speeds.

Abstract: In a two-level overlapping polysilicon device even the slightest amount of undercutting of an oxide layer (12) which underlies a first polysilicon layer (14) can lead to unacceptably low breakdown voltages in the device. In accordance with the invention, the first polysilicon and oxide layers of an LSI MOS wafer are defined as usual. But then the standard fabrication process is modified to etch the first polysilicon layer back beyond the edge of the oxide undercut. Subsequently, the structure is reoxidized and a second polysilicon layer (22) deposited and patterned. The modified process is characterized by the absence of any oxide thinning between the first and second polysilicon layers or between the second polysilicon layer and the substrate (10) of the device. As a result, voltage breakdown problems in the individual chips of the wafer are thereby greatly reduced and the yield of the wafer significantly increased.

Abstract: A sealed primary cell includes a metal receptacle (1), a metal cover (2) which closes the receptacle and a hard and resilient thermoplastic sealing ring (3) which may optionally be coated with a softer material (not shown). The sealing ring (3) is inserted between the cover (2) and the internal wall of the receptacle (1) and is radially compressed between the cover (2) and the receptacle (1). The invention is characterized in that the radial compression of the sealing ring (3) is achieved by radially outward deformation of the outer edge of the cover, e.g. by an auricular portion of a tool (7) enlarging a U-shaped peripheral rim of the cover. FIG. 2 shows the cell held in a die (9) after the sealing ring (3) has been radially compressed by the tool (7) but before the cell is finished by the usual inward crimping of the upper rim of the receptacle (1).
