摘要:
A semiconductor-encapsulating epoxy resin composition comprising (A) an epoxy resin, (B) a phenolic resin curing agent, (C) an inorganic filler, and (D) carbon black is prepared by mixing a carbon black feedstock and the curing agent with an organic solvent, filtering off coarse particles of carbon black which remain over a mesh sheet with an opening of 20 μm, removing the solvent from the filtrate to yield a premix of curing agent and carbon black, and kneading the premix with the remaining components.

The present abstract refers to a utility model patent for a raising mechanism (1) of a movable lower grill grid (103), in the field of barbecue grill components and comprising: lever (2), mounted to the lateral columns of the frame (100) of the barbecue grill and an axial spindle (3) provided in its middle point; a cross-sectional rotary axis (4), arranged below the fixed upper grill grid (101) and a toothed wheel (5) whose one end engages the spindle (3); pulleys (6) mounted to the respective ends of the axis (4); and steel cables (7) whose ends are mounted to the pulleys (6) and the lower ends mounted to the lateral tabs (8) of the lower grill grid (103); a casing for housing and protecting the mechanism substantially consisting of: two hollow columns (10), located in the middle points of the frame sidewalls (100) house the spindles (3), gears (5), pulleys (6) and steel cables (7), and feature longitudinal notches (11) turned inside the barbecue grill receiving the tabs (8); and a hollow upper cross member (20) mounted between the upper ends of the columns (10), arranged under the fixed upper grill grid (101), and which houses the axis (4); and a device (30) for adjusting the lever (2) to the masonry “wind screen”.
摘要:
A raising mechanism of a movable lower grill grid formed with a hand crank mounted to lateral columns of a frame of a barbecue grill and a worm provided in a middle point of the hand crank. A cross-sectional rotary axis is arranged below a fixed upper grill grid and a worm wheel with one end engages the worm. Pulleys are mounted to respective ends of the axis. Steel cables include ends mounted to the pulleys and lower ends mounted to lateral tabs of the lower grill grid. The mechanism also includes a casing for housing and protecting the mechanism.

The present abstract refers to the application for a utility model patent covering a grill belonging to the field of home utensils, which received an arrangement to enable the preparation of a barbecue to the “open flame” style in a gas oven, essentially comprising: a base platter (1) supported over the gas burner (50) of an oven and provided with a middle opening (4) receiving the flame; a bell-shaped container (10), which is coupled and supported over the base platter (1); a heat diffuser (20) supported over the base platter (1) above the opening (4) and receiving an amount of charcoal (52); and a set of vertical skews (30) and baskets (31) with the tips supported over circumferential braces (6) of the base platter (1) around the opening (4); said skews and baskets remaining with intermediate sections supporting the meat along the bell-shaped container (10), and upper outer ends close to the cables, coupled with upper streaks (16) extending radially from the upper opening (14) of the bell-shaped container (10) which receives the cap (15).
摘要:
An epoxy resin composition is provided that mainly comprises an epoxy resin, a curing agent, and an inorganic filler, and that cures into a product having a coefficient of water diffusion of up to 1.times.10.sup.-4 cm.sup.2 /hr. at a thickness of 3 mm under humid conditions at 85.degree. C. and RH 85%, wherein 1-50% by weight of an inorganic water absorbing agent such as molecular sieve, silica gel and porous silica is added to the epoxy resin composition. The composition offers cured products having fully low moisture permeability and is thus suitable as a pre-molded hollow package-forming material.
