Title: Furnace grid coil, in particular for waste incineration, with breathing tube made of bar rings separated by blowing intervals of constant width
Inventor: LE LAN ANDRE
IPC: F23H11/12
Filed: 1990-05-24
Abstract: The grate roll, of conventional structure, has a framework in the form of a cylindrical cage with longitudinal members (10) with a T- shaped profile arranged according to generating lines, and a lining formed from groups (G) of rings separated by gaps (i) for blowing oxidant air, the rings being segmented into bars ((1-6).11, (1-6).11') in the form of arcs which extend between the longitudinal members. According to the invention, in order to limit the clearance of the bars while leaving them play, they are, attached on one side by an indentation to the wing of a longitudinal member, held in position by bosses ((1-6).128, (1-6).129) of an interposed piece (12) bolted longitudinally onto the longitudinal member; the bars ((1-5).11, (1- 5).11') have recesses at their end which is contiguous with the intermediate piece (12), in which the bosses engage. The bars are thus attached with limited clearance in the axial, radial and peripheral directions in relation to the roll.

IPC: B32B15/08

Abstract: A photocurable resin laminate comprising a support and a photocurable resin layer disposed on one surface of said support, said photocurable resin layer having:         (a)  a viscosity of from 104 to 5 x 105 poises as measured at 90 °C;         (b)  a thickness of from 30 to 150 µm; and (c)  an ultraviolet ray transmittance of from 40 to 95 % with respect to ultraviolet rays having a wavelength of 365 nm.    When this photocurable resin laminate is laminated under pressure on both surfaces of a metal-clad insult-ing base board having through-holes of an inner diame-ter smaller than 0.5 mm so that both surfaces of the metal-clad insulating base board are covered with the photocurable layer of the photocurable resin laminate, the photocurable resin layer intrudes locally in the inner side of the inner circumferential edge of both terminal openings of each through-hole and extends from the inner circumferential edge along and on the inner wall of the through-hole to a predetermined depth.  By the light exposure of such a laminate structure and the subsequent development, both terminal openings of each through-hole can be completely covered with a photo-cured resin layer without occurrence of coverage fail-ure, wherein a photocured resin layer adhering to the inner wall of the through-hole is formed in the through-hole from the inner circumferential edge of the terminal opening thereof along and on the inner wall of the through-hole.  Accordingly, when the subsequent etching with an etching solution is performed to remov-ing unnecessary conductive layers in areas other than the desired circuit portions, a printed circuit board having small-diameter through-holes can be obtained in which the electric conduction between both surfaces of the board which is established through the through-holes has high reliability.

Title: Method of depositing directly activated species onto a remotely located substrate
Inventor: DOEHLER JOACHIM
IPC: C23C14/38
Filed: 1990-08-13
Abstract: A method of depositing high quality thin film at a high rate of deposition through the formation of a high flux of activated precursor species of a precursor deposition gas by employing a substantial pressure differential between the pressure adjacent the aperture in a conduit from which said precursor deposition gas is introduced into the interior of a vacuumized enclosure and the background pressure which exits in said enclosure.  As the precursor deposition gas is introduced into said enclosure, a high density plume of said activated precursor species are formed therefrom due to an electromagnetic field established in an activation region adjacent said aperture.  The pressure differential is sufficient to cause those activated precursor species to be deposited upon a remotely positioned substrate.  In order to obtain a sufficient pressure differential, it is preferred that the flow of the precursor deposition gas reaches transonic velocity.  And in order to obtain a high quality thin film, it is preferred that the plume of activated precursor species is spaced from the substrate; without structural or electrical confinement, a distance from the activation region greater than the mean free path of undesired activated precursor species and within the mean free path of desired species.

Title: Delay-based congestion avoidance in computer networks
Inventor: JAIN RAJENDRA K
IPC: H04L12/56
Filed: 1990-08-17
Abstract: DELAY-BASED CONGESTION AVOIDANCE IN COMPUTER                     NETWORKS            ABSTRACT   A packet data communication system employs a congestion avoidance method in which each node measures the round-trip delay occurring when it sends data to a destination and receives an acknowledgement. This delay is measured for dif-ferent load levels, and a comparison of these delays is used to determine whether to increase or decrease the load level. The load level can be adjusted by adjust-ing the window size (number pf packets sent in to the network) or by adjusting the packet rate (packets per unit time). The objective is operation at the knee in the throughput vs. traffic curve, so that the data throughput is high and theround trip delay is low. Control is accomplished at each node individually, without intervention by the router or server, so system overhead is not increased.

Title: Heatable turntable
Inventor: ROCHA OCTAVIO
IPC: H05B3/68
Filed: 1990-10-22
Abstract: A heatable turntable is provided for efficiently warming and serving food. A deck is rotatably mounted on a base. Electrical current is supplied from a power supply in the deck to thermal pads located in the deck via wires connected to sliding pole pieces attached to the base and deck. Individual thermostats are provided for each thermal pad to prevent overheating when a pad is unoccupied. Each thermal pad is located within a recess in the deck such that each pad extends out of the recess to permit air to flow between the deck and an object placed on the pad, whereby efficient heat exchange is promoted. Also, each thermal pad has a heating element comprising a resistance plate sandwiched between two mica insulation plates. The heating surface of each pad can be concave shaped towards this sandwich and has a lower lip which compresses the sandwich towards the heating surface. In addition, the sandwich is biased towards the concave heating surface by a screw actuated bracket. A system of heating turntables is also provided by electrically interconnecting a plurality of turntables.

Title: Water kettle
Inventor: KUHN JACQUES
IPC: A47J27/212
Filed: 1990-11-07
Abstract: Abstract of the Disclosure A water kettle is equipped with a handle, a first end of which is joined to lower regions of the side of the kettle by a hinge, and a second end of which is fitted on the diametrically opposite side with a spout lid for covering (and opening) the kettle's spout.  When the kettle is in the rest position, as a result of its weight the handle will drop until the handle comes to stop on the spout and the spout lid covers the spout opening. When the kettle is lifted by the handle or tipped into the pouring position, the handle swings back to a stop is the spout and the associated spout lid is removed from the spout opening. Following this swiveling movement, the raised spout lid is brought into a position which deflects steam flowing out of the spout opening in such a way that a user's hand holding the handle is not directly exposed to the steam.  The spout lid is provided with a device for emitting an acoustic signal when the boiling point is reached in the interior of the kettle.  If desired, the water kettle may further include a second, larger filling and cleaning opening which is enclosed by a close-fitting lid to facilitate filling and cleaning of the interior of the kettle.
