Abstract: 전기화학적 열원을 구비한 담배 흡연제품을 개시한다. 불연성 열원에는 마그네슘, 철 또는 니켈 등과 같이 서로 전기화학적으로 반응할 수 있는 2가지 이상의 금속물질이 들어있다. 이 금속물질들은 용융 응고물, 바이메탈호일, 다른 종류의 금속물질 스트랜드 둘레를 감싼 제 1 금속 와이어, 및 기계적 합금 등 다양한 형태로 제공된다. 이 금속물질들은 분말로 채워진 스트로 형태 또는 결합제와 섞여 봉 형태로 압출되거나 압축되는 작은 금속입자들 형태로 될 수도 있다. 분말로 채워진 스트로나 봉은 담배로 둘러싸인 히트 챔버로 교체될 수도 있다. 히트 챔버 안의 금속물질은 전해질 용액과 접촉하여 전기화학적 반응을 시작해 열을 발생시키고, 이 열로 인해 담배의 니코틴과 향미 물질들이 휘발된다. 
     담배에서 향미성 기질을 제조하는 공정도 기재되어 있다. 이 공정에는, 제 1 단계 가열중에 담배를 제 1 토스트 온도로 가열하여 휘발성 물질들을 배출하는 단계: 상기 토스트 온도를 제 2 단계 가열중에 제 2 토스트 온도까지 상승시키고, 제 1, 제 2 토스트 온도에서 배출된 휘발성 물질들의 적어도 일부분을 향미성 기질로서 별도로 수거하는 단계를 포함된다. 담배를 냉동 건조한 다음 건조된 담배를 가열하는 등에 의해, 휘발성 향미성 성분들을 제거하지 않고도 담배의 수분을 감소시키는 것이 바람직하다.

Title: Pressure medium drive for closing and opening the contacts of a circuit breaker
Inventor: DUFFOUR HENRI
IPC: H01H33/32
Filed: 1992-09-04
Granted: 2000-08-01
Abstract: The pressure medium drive is provided for opening and closing the contacts (e1, e2) of an electric circuit-breaker. It contains a pressure medium reservoir (r), a drive piston (t) which slides in a drive cylinder (c) and acts on a mechanism (j) for displacing a movable contact (e1) of the circuit-breaker, and a reversing valve (s) for the selective connection of the pressure medium reservoir (r) to the drive cylinder (c) or of the drive cylinder (c) to an outlet volume for the pressure medium. This pressure medium drive is of simple, inexpensive construction and can open the contacts of the circuit-breaker considerably faster than it can close them. This is due to an interposed valve (v) which is disposed between the pressure medium reservoir (r) and the reversing valve (s) and has a flow cross section determined by the closing time of the contacts (e1, e2), and to the much larger flow cross section of the reversing valve (s). This interposed valve (v) is open when closing the contacts (e1, e2) and passes pressure medium from the pressure medium reservoir (r) via the reversing valve (s) into the drive cylinder (c). After closing of the contacts (e1, e2), it is closed and then establishes the connection between the drive cylinder (c) and the outlet volume by reversing the reversing valve (s).

Title: Borehole Cross-Section Steering
Inventor: JONATHAN MARSHALL
Filed: 2020-09-24
Abstract: A drill bit forming a borehole in the earth may be urged sideways, creating a curve in the borehole, by a cross-sectional shape of the borehole. For example, a borehole with a cross-sectional shape comprising two circular arcs of distinct radii, one larger and one smaller than a gauge of the drill bit, may push the drill bit away from the smaller circular arc and into the larger circular arc. Forming a borehole with such circular arcs may be accomplished by extending a cutting element from a side of the drill bit for only a portion of a full rotation of the drill bit. The radii and angular ranges occupied by these circular arcs may be adjusted by altering the timing of extension and retraction of the extendable cutting element. Fig. 1.

and a lightning protection section; a plate-shaped electrode is on one side of the insulation 
section; a zinc oxide resistor disc is sleeved over the insulated support; one end of a spherical 
electrode leading-out part is connected to a spherical electrode, the other end electrically 
connected to the zinc oxide resistor disc; a silicone rubber umbrella cover is sleeved over the 
insulated support of the insulation section and the zinc oxide resistor disc; a distance from the 
spherical electrode to a standard straight line is dl, a distance from an edge of the plate-shaped 
electrode away from the standard straight line to the standard straight line is d2, a distance from 
an edge of an umbrella skirt away from the standard straight line to the standard straight line is 
d3, and dl>d2>d3.
