Abstract: PCT No. PCT/DE88/00440 Sec. 371 Date Jan. 29, 1990 Sec. 102(e) Date Jan. 29, 1990 PCT Filed Jul. 16, 1988 PCT Pub. No. WO89/01083 PCT Pub. Date Feb. 9, 1989.A form for the pouring of concrete has first and second panels which are disposed edge-to-edge. Each of the panels has a flange projecting from the major surface of the respective panel and the flanges have confronting first surfaces which are perpendicular to the major surfaces of the panels and are designed to abut one another. The flanges have second surfaces which face away from the first surfaces and the second surfaces are inclined to the major surfaces of the panels so that the flanges narrow in a direction away from the panels. A clamping element designed to embrace the flanges is pivotally mounted on the first panel and is movable between a released position and a clamping position in which it embraces the flanges. The second panel carries an abutment and the clamping element has a free end which is located between the abutment and the flange of the second panel in the clamping position. A wedge-like slide is mounted on the free end of the clamping element for movement between a retracted position and an extended position. The arrangement is such that, when the clamping element is in its clamping position and the slide is moved to its extended position, the slide pushes against the abutment thereby causing the clamping element to urge the flanges into engagement with one another.

Granted: 1999-03-20
Abstract: In a color television system, the color signals produced by a luma-chroma IC (154) are summed (171,173,175,177) to produce a signal representative of processed luminance information not otherwise readily available. Pulses of the summed signal corresponding to retrace blanking pulses contained in the color signals, are stripped away in order to reduce errors when attributes of the. summed signal are determined, e.g., by an average detector (183). The detector provides a control signal for modification of a luminance signal, such as by "white stretch" (136).

Granted: 2000-12-15
Abstract: PURPOSE: Provided is a modified polyester resin composition, which is a fast crystallizing rigid moldable or extrudable material and has improved surface properties and demoldability and reduced plate-out characteristic during a molding process. CONSTITUTION: The modified polyester resin composition comprises: (A) about 70-94 wt% of a poly(ethylene terephthalate) resin having an intrinsic viscosity of about 0.7-1.1 dl/g; (B) about 4-29% of a core/shell polymer having (i) about 60-90% of a first elastic stage polymer polymerized from (a) at least 75% of alkyl acrylate or butadiene, optionally (b) up to about 5% of a crosslinking monomer and optionally (c) up to about 5% of a graft monomer, (ii) about 10-40% of a second rigid stage polymer polymerized from a monomer system including at least 55% of C1-C4 alkyl methacrylate, (iii) optionally up to about 5 wt% of an inorganic nucleating agent, and (iv) optionally up to about 5 wt% of one or more heat and/or oxidation stabilizers; (C) about 1-8% of an aromatic carbonate; and (D) about 1-5% of a copolymer of an ester group-containing vinyl or vinylidene monomer with ethylene, wherein the content of ethylene is less than about 99% and the copolymer contains no acid or acid salt functional groups.

Title: Machine for cooking meat by radiant heat of far infrared rays
Inventor: YUN MOO-WON
IPC: A23L13/00
Filed: 1993-08-26
Granted: 1996-06-19
Abstract: The unit consists of a door at the front(6), an outlet(3) on the main body(2), a bent heat reflecting plate(12) set with a gap in the main body, far infrared radiating plates attached on the bent reflecting plate(12-1), far infrared radiating stones(11) on the infrared radiating plate(10-2), a gas burner under the plate(10-2), a oil collecting unit(5) in front of stones(11) separated with a block(5-1), and meat rotating parts(7) over the oil collecting unit(5). The far infrared radiating plates(10)(10-1)(10-2) and the radiating stones are made of 15-30% germanium, 5-10% cerium and 50-80% kaolin.
