Patent EP-0399245-A2 (EP)
Inventor: BIRKELBACH HEINRICH
IPC: F24C3/04
Filed: 1990-04-28
Abstract: The aim is to design a gas heating installation, which is suitable in particular for tiled stoves, with a simple and expedient construction in such a manner that the advantages of tiled stoves, that is to say high thermal comfort by means of a high proportion of radiant heat and free design possibilities of the tiled stove, are also maintained in the case of firing with gas. This is achieved, by using gas heating elements (1) with a radiant burner (7) and with a cover plate, preferably made of a heat-resistant, transparent material, such as glass ceramic or the like, in that each gas heating element (1) has on its housing underside and its housing upper side insertion connections (20, 21) aligned coaxially with one another, such as pins, sleeves or the like, which interact with coaxially aligned bearing points on a lower support frame (23) and an upper waste gas collector (24) parallel thereto, the support frame (23) and the waste gas collector (24) being connected by a front panel frame (25) and each gas heating element being pivotable and fixable about the vertical axis (26) defined by the bearing points. As a result of this, the gas heating elements, in relation to the support frame and the waste gas collector, can according to requirements be freely rotated, fixed and thus optimally aligned in a simple manner onto the inner walls of the tiled stove which are to be heated. This makes possible optimal individual action upon the inner tiled stove surfaces by radiant heat and opens up very variable possibilities of use in the most different tiled stove shapes, with simple installation and removal using a small number of standardised components. <IMAGE>

Abstract: Calculations are made to find the differences, Δij=fij-f0, between the value of an image signal component f0 representing a picture element P0 in a radiation image and the values of image signal components fij representing the picture elements Pij, which are located on each of a plurality of lines Li, where i =1, 2, ..., n, extending from the picture element PO to the peripheral parts of the radiation image, and which are spaced a plurality of distances rij, where j = 1, 2, ..., m, from the picture element P0. A representative value, which is representative of the differences Δij, is then found for each of the lines Li. A mean level value of two representative values for each set of two lines, which extend from the picture element PO in approximately opposite directions, is then calculated. From the mean-level values, which have been calculated for a plurality of the sets of lines, a judgment is made as to whether the picture element PO falls or does not fall within the region corresponding to a circular pattern in the radiation image.

Abstract: A technique for compensating for variations in a resistor set overall gain switched-capacitor circuits, such as high accuracy digital-to-analog converters (10). The variation is overall gain from the desired gain is due to the variation in the total capacitance of the capacitors (15₁---15 N ), compared to the variation in the resistance of the resistor (19), in the circuit during manufacture. A bias circuit (11,12) with two reference voltage outputs, is adapted to have a capacitor (31) and a fixed resistor (30) vary one of the voltage references depending on the capacitance thereof. The voltage difference between the two voltage references varies the overall gain of the switched capacitor circuit to compensate for variations in the overall gain. Also, a switched-capacitor digital-to-analog converter (10) utilizing the above technique is presented.

Abstract: Polymeric acetals of polyvinyl alcohols grafted onto polyalkylene oxide graft bases or polyurethane graft bases which contain acetal groups derived from etherified  omega -hydroxy(poly)-alkoxyalkanals of the formula (I), and a process for their preparation by acetalisation of appropriate graft polyvinyl alcohols, are described.   The polymeric acetals according to the invention are internally plasticised and are polymers which are generally obtainable in solid form and can be converted thermoplastically without external plasticisers to films, mouldings or coatings. Mixed acetals with other aldehydes can also be prepared and enable properties to be varied widely, including the solubility in water or in organic solvents. The polymeric acetals according to the invention can be processed or used without solvents, for example from the melt, or as organic or aqueous solutions or as aqueous dispersions. The diverse solubility spectrum, the glass transition temperatures which are significantly lowered compared with polyvinylbutyral, the thermoplastic processability without external plasticisers, the external crosslinkability, the good adhesive capacity to diverse solid materials, the corrosion-neutral behaviour toward metals and the dispersion capacity in aqueous media enable the polymeric acetals according to the invention to be used in a broad industrial area, in particular, for example, as binders in organic or aqueous solutions or dispersions or in products to be used as liquid melts, preferably in paints, coating compositions, adhesives, dispersants, pigment binders, printing inks, green ceramic sheets, sizes, fibre binders, paper, photographic printing plates, photoresist materials, and as mouldings and transparent interlayer films for composite glasses.

Abstract: A method for transmission of variable length code words is provided in which the variable length code words are allocated into a data storage field not only from the front end of the same but also from the rear end, whereby unwanted affection by transmission error will be minimized. A coding apparatus produces coded data of such a format that after different type video signals are divided into a common signal area and a not-common signal area, the coded data of the common signal area is allocated into one data storage field in a sequence from the front end of the same and the coded data of the not-common signal area is allocated in a reverse sequence from the rear end. Accordingly, such different video signals can successfully be decoded with a decoder designed for processing one particular video signal.

Abstract: A method and apparatus for manufacturing a superconductor wire has a wire take-up spool (16) and a feed speed control spool (12). A wire substrate (22) is taken from the feed speed control spool (12) and onto the take-up spool (16) as the wire take-up spool (16) is rotated. The wire (22) passes through a container (36) which holds a diffusion barrier material (50), where the diffusion barrier material (50) is electrophoretically deposited onto the wire substrate (22) and subsequently sintered. The wire (22) is also passed through a container (36a) which holds a superconductor material suspended in solution (38a), and a layer of the superconductor material (70) is electrophoretically deposited onto the diffusion barrier (50). The grains of the superconductor layer (70) are then magnetically aligned and sintered. Also, a silver coating (76) is electrophoretically deposited onto the superconductor layer (70) and sintered. A diffusion bonding inhibitor material (78) is then applied to the silver coating (76). Then, the silver-coated superconductor wire is spooled and heated to 400°C for one day to oxidize the superconductor layer (70).

Abstract: In the case of power circuit breakers and protective switches which are of modular construction, the accessory parts should also be as space-saving and compact as possible in order to keep the dimensions of the switch housing within the limits and also to ensure accessibility to the relevant components. In the case of a trip unit (1) for power circuit breakers and protective switches which is designed especially as an undervoltage trip unit, this is achieved in that a switching or tensioning pin (12), which projects from the lock mechanism (8) of the switch to the side, acts on the tensioning lever (9) of the trip unit (1), which lever is constructed as a single-armed lever and pivots about a rotation axis (14) which is arranged on the housing (13) of the trip unit (1) at right angles to the trip plunger (7), and acts by means of at least one pressure point (15), which is located between its free lever end and the rotation axis (14), on the first lever arm (16) of the trip lever (10), which is constructed as a two-armed rocker and is supported on the end of the housing (13) located adjacent to the plunger head (17) of the trip plunger (7) such that it can pivot about a rotation axis (18) which is parallel to the rotation axis (14) of the tensioning lever (9), such that, when it is acted on by the tensioning lever (9), it presses by means of its second lever arm (19) the spring-loaded trip plunger (7) against the trip coil (5), and such that a trip arm (20) is directed against the lock mechanism (8) from the second lever arm (19), which trip arm (20) operates the trip latch (11) on the latching mechanism when the voltage is inadequate so that the switch can remain such that the contacts do not touch and it is not switched on. <IMAGE>
