Abstract: Prior art high temperature electric furnaces of the type using two or more, usually three, primary electrodes positioned around an electrically conducting central outlet brought the electrodes in through a side or bottom wall of the furnace at points below the melt line causing many problems. The present invention provides a primary electrode arrangement for such melting furnaces wherein the primary electrodes do not pass through the wall or bottom of the furnace below the melt line, but instead enter the furnace over the top of the melt line and then protrude through the top surface of the melt. The primary electrodes of the present invention are provided with means for preventing wear and deterioration at the interface between the top surface of the melt and the unmelted batch and/or the oxidizing air atmosphere surrounding the top of the furnace. The improved furnace of the present invention does not require the use of a purging neutral or reducing atmosphere to protect the primary electrodes.

Abstract: A drainage board is used for supporting sheets of chips or fibre from wood or other lignocellulose materials when hot-pressing same to form boards. This drainage board has slits 19 lying comparatively close together, and these slits, towards the upper surface of the board, are sufficiently narrow to prevent the sheet material slipping through, while allowing vertical drainage. Towards the lower surface they are made considerably wider as they continue out into the open so that, when pressed together with the underlay, drainage channels 21 are formed which are sufficiently spacious to allow for horizontal drainage without causing any harmful pressure- rise in them. <IMAGE>

Abstract: A target for night-time gunnery and similar practice with the use of a heat responsive sight comprises a thin, supple fabric supported on a rigid frame to be substantially flat, with a front surface facing towards a location from which firing takes place. The fabric comprises a front protective sheet, preferably plastic, which is transparent to infra-red radiation, and a rear radiation-absorbing sheet of low heat capacity, preferably foil. A coarse-mesh net, between said sheets and secured to both, holds them spaced and parallel to cooperate in defining a heat insulating air space between them. An infra-red radiator heats the heat-absorbing sheet, which preferably has a radiation absorbing matte coating on its rear surface and a colored front surface coating. When warmer than its surroundings, the heat absorbing sheet thus radiates as a black body. With one or both coatings having different densities in different areas, the target image in a heat responsive sight can closely simulate that of a specific heat-emitting object which might have to be engaged in combat.

Abstract: When joining insulated pipes 1, 2 connected at different angles, preferably heating pipes, consisting of an inner tube 3 in which a fluid is transported, a layer of insulating material 4 and a cover 5, a pipe bend 6 having a suitable curvature is connected with the inner tube 3 in one 1 of the pipes. A cover 7 is affixed and displaced over the connected ends A, B such that the other end B of the pipe bend 6 becomes freely accessible and can be connected with the inner tube 3 of the other pipe 2. The cover 7 on the pipe bend 6 is then displaced towards the centre of the latter, and affixed cover parts 8 on the cover 5 on each pipe end are guided towards the ends A, B of the pipe bend and connected with the cover 7. Insulation material is subsequently introduced through an opening 10 in the cover part 8 which is then connected. By this method, stocking of a large number of different pipe bends with mounted, very space-consuming insulation, is avoided. <IMAGE>

Abstract: In a color television receiver including a comb filter for separating luminance and chrominance components of a color television signal, a network is included for selectively restoring and enhancing vertical image detail to preserve and enhance vertical resolution in the luminance content of a displayed image. The comb filter provides a combed luminance signal output from which vertical detail signal information has been unavoidably deleted, and a combed chrominance signal output including signal frequency components representative of the deleted signal, which are selectively extracted from the combed chrominance signal. Low level detail signals are restored to the combed luminance signal via a first signal processing network with a prescribed restoration gain. The detail signal is also combined with the combed luminance signal via a second signal processing network which cores (removes) low level detail signals including noise, and enhances higher level detail signals through amplification to enhance vertical image definition. A resultant reconstituted luminance component manifests restored low level vertical detail information as well as enhanced higher level vertical detail information, without enhancing unwanted signal components such as noise.
