Title: Electrical heating element comprising a helix of wire wound on at least one insulating plate
IPC: H05B3/06
Filed: 1977-09-22
Abstract: A heating element comprises a resistance heating wire formed with closely adjacent zigzag loops and wound helically on an insulating plate or a pair of such plates mounted crosswise and possibly narrowing conically towards one end. Opposite loops engage the respective edges of such insulating plate, possibly in notches in those edges, and may be pressed on to those edges. The plate may have holes near its edges, the engaging loops being formed with kinks which clip into the holes. Spring clips may be provided for electrical connections to such loops at the edge of such plate and may also be formed with kinks which clip into the said kinks of the loops. The electrical connection to such spring clip may be a cable rivetted, eyeletted or soldered to a cross-piece interconnecting the legs of the clip or may comprise an angled tongue formed at the end of one of the legs to receive a flat plug-in connector. A temperature regulating device may be located within the helical winding and may be readily connected to the heating element by means of such connectors.
Patent ES-467042-A1 (ES)
Title: Photographic type composing machine
IPC: B41B17/00
Filed: 1978-02-16
Abstract: The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums. The characters are located in arrays such as concentric rows on a disc. A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage. Character spacing is determined by motion of the lens carriage and/or the lamp carriage. Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage. Composition of lines or columns of characters taken from a relatively large number of different arrays, such as would be the case in type composition using Chinese ideographs, is speeded considerably by controlling the order in which the characters are projected so that the lens carriage need not reverse its direction of motion during composition of a line. A simple mechanism is used to change lenses for size changes by the selective use of stops at the ends of the travel path of the lens carriage. Two discs or drums can be used alternatingly to increase the number of characters available. A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like. This avoids the necessity of providing a separate headlining machine. Another simple attachment is provided for inserting Pi characters. This attachment makes use of the lamp carriage and drive mechanism in selecting the Pi characters for projection. A method which is especially useful in economically producing large matrix discs is described. An economical "floppy" or flexible film disc also is described. A system and method are described for electronically detecting base-line and spacing errors in the characters on the character matrix, storing the errors, and correcting the errors electronically during projection of the characters onto the photographic film.

Title: Railway carriage heating system - uses electric elements inside cover grill at floor level with vents taking some heated air to window level(PT 14.1.81)
IPC: B61D27/00
Filed: 1980-07-24
Abstract: The railway carriage heating system includes a radiator (10) extending along the floor (12) of the carriage. Cold air enters the heating chamber (20) via holes in the cover plate, and leaves via further holes (16,18) in the front and upper surfaces of the cover. Electric heating elements (56,58) lie parallel inside the heating chamber and are bolted to the front panel (22). Insulators on the bolts (68,70,72) separate the heating elements from deflectors (88) and the front panel. Some of the air heated by the electric elements rises through a space between panels (32,34) of the carriage walls to emerge through higher vents. The highest of these lie immediately below the glass of the window so that the rising hot air counteracts the effect of cold air descending from the window pane. The system provides for uniform heating of the space within the railway carriage.

Title: Temperature control method and apparatus for a glass sheet in a plural-cell furnace.
IPC: C03B23/023
Filed: 1981-08-05
Abstract: The invention relates to a process for regulating the temperature of a glass sheet in a furnace as the glass sheet is moved at a determined rate and heated according to a preestablished program. The furnace is characterized by only slight thermal inertia thereby to provide rapid adjustment of the internal temperature within each of several cells. The physical presence of the glass sheet is checked in synchronization with its step-by-step advance at least at one location upstream of one furnace cell to correct the regulation of the radiation heating output should these be a variance from that of the preestablished program. The process may be carried out with limited fabrication rejects by virtue of the capability of regulation of variations of the conveying rate or as required due to gaps in the succession of glass sheets being treated.

Patent ES-8302912-A1 (ES)
Title: Method and apparatus for analyzing ore by means of gamma radiation
IPC: G01N23/22
Filed: 1981-09-14
Abstract: Disclosed is a method and an apparatus for analyzing pieces of ore for the purpose of sorting. Each piece falling by the analyzer is irradiated individually by means of two gamma radiation sources operating at different energy levels so selected that, as to the scattering effect, at one level the Compton effect is predominant and at the other level the Compton effect and the photoelectric effect compete with each other. The former effect is strongly dependent on the ordinal number of the element and, thus, by detecting with at least one detector the scattering intensities produced with the said two sources of radiation and comparing the scattering intensities with each other, the proportion of heavy elements in the ore piece can be determined and the ore piece can be classified on the basis thereof. For example, one energy dispersively operating scintillation detector can be used for detecting the scattered radiation.
