Title: Method for making pitting resistant cast iron product
Inventor: YAMAMOTO YUZIO
IPC: C21D5/00
Filed: 1983-08-20
Granted: 1989-07-20
Abstract: The pitting resistant cast steel product is made from a ferrous alloy containing 2.8-3.8 wt.% C, 1.8-2.8 wt.% Si, 0..5-1.0 wt.% Mn, 0.2-1.0 wt.% Cu, 0.2-1.0 wt.% Ni, 0.5-1.5 wt.% Cr, 0.4-1.5 wt.% Mo, up to 0.15 wt.% P, up to 0.1 wt.% S and balance Fe.  The sliding face of the structure is formed as a chilled casting surface containing 30- 50% precipitated cementite.  The cast product is annealed at 550-630 deg.C for 20-60 minutes before machining.  It is then reheated to 850-950 deg.C for 1-10 minutes, before quenching to give a product having a martensite matrix with no decomposed cementite.  Finally it is tempered at 100-250 deg.C for up to 120 minutes.

Title: Easy release tension reliever
Inventor: STAMBOULIAN NAZARETH
IPC: B60R22/44
Filed: 1983-08-29
Granted: 1989-03-08
Abstract: A releasable pawl (28) for engaging a ratchet wheel (26) comprises a first member (34) pivotally mounted on one end by a pivot (30) for pivotally mounting the pawl and a second member (36) adapted on one end to engage the teeth (32) of the ratchet wheel.  The other ends of the members are joined together by a hinge (38).  Shoulders (40) on the other ends of members are provided to cause the hinge to lie below a line drawn from a center of the pivot to a tip of the pawl when the pawl members are in the locked position.  The hinge is then in an over-the-center state, causing forces applied to the pawl by the ratchet wheel to hold the pawl members rigid in such over-the- center state.

Title: Steam pressure cooker
Inventor: BECKE REINHARD V D
IPC: A47J27/08
Filed: 1984-08-25
Granted: 1991-02-21
Abstract: The invention relates to a steam pressure cooker, which essentially consists of a lower pot and a cover unit sealing the lower pot. The lower pot has a smooth circular pot rim. The cover unit consists of a lower lid and an upper lid. The latter is designed as a sealing element, which engages the lower part of the pot rim by the flanges. As an improvement of this type of pressure cooker, it is proposed that the upper lid contain two half-lids, and that each half-lid be able to rotate about its own axis of rotation essentially parallel to the central axis of the pot (geometrically vertical) relative to the lower lid and lower pot, and further, that the axes of rotation lie eccentric to the pot's central axis and diametrically opposite each other with respect to this axis swivel mechanism rotatably supported concentrically on the lower lid.

Granted: 1990-01-24
Abstract: A light from an external source is transmitted by optical cable to an optical-fluid-filled transparent cylinder and radiated outwards by a reflecting piston structure, movable up and down the cylinder by displacement of fluid from one side of the piston to the other.  The reflecting structure receives light beams from two directions and has both ends formed as inclined reflection surfaces with the inclinations such that both surfaces reflect light in the same direction.  The reflectors have a finite thickness and present additional internal reflecting surfaces separated by the prism-shaped cavity.

Abstract: 내부전반사(TIR)홀로그램에 의한 고화질 영상 마스크 
     내부전반사 홀로그램에 의해 생성된 영상에 불필요한 프린지 패턴을 줄이거나 제거하기 위해, 마스크(20)는 그 마스크의 하측면(26) 및 상부면(16) 중의 적어도 한 면에 반사방지막(19)을 형성시킨다. 또한 마스크(20)의 하측면(26) 상에 형성한 반사방지막(19)은 내부전반사 홀로그램에 의해 생성된 영상의 초점 심도를 개선하게 된다.
