Patent YU-6898-A (YU)
Title: Universal drier
Inventor: MILIJA UROSEVIC
Filed: 1998-02-19
Abstract: Universal drier consists of chamber (1) for material drying, heat aggregate for indirect heating of air conducted into aggregate chamber (23), griddle (10) at the bottom of chamber (1) for drying, ventilator aggregate (6) where, beside the ventilator (18), there are two bar connected clamps (20) used for alteration of the direction of heat exchange in air flow in the drier. The heat aggregate consists of the hearth furnace (2) and tube heater matrix (3). At the end of the hearth, there is a griddle (12) placing bellow an ashtray with the distributor (26) of primary air. Drying is performed by the hot air conduction through the layer of material in the chamber (1) with the occasional change of the direction of the air flow. The heating of air is performed by its flowing along the vertical sides of hearth (2) and double conduction between the tube heater matrix (3). In the hearth, solid fuel is burned. The distributor (26) of primary air is connected through regulator (7) of primary air conduction with the compressing side of ventilator aggregate.
Patent DK-50784-A (DK)
Inventor: THALMANN ALFRED
IPC: B29C65/22
Filed: 1984-02-03
Abstract: A system for heat-sealing thermoplastic conduits involves a thermoplastic sleeve surrounding an electrically conductive heating wire arranged in a coil. A bridging conductor is located adjacent the heating element, but is separated from it by an insulation layer of predetermined thickness. When the sleeve is heated by supplying electric power to the heating element, the entire heating element generates heat during a first phase in which fusion pressure is applied between the sleeve and pipes being connected. The bridging connector is forced into contact with selected coils of the heating element to initiate a second phase. In the second phase, the heat produced in the area of the selected coils is automatically reduced by short circuiting such coils.
Patent DK-83891-A (DK)
Inventor: POULSEN OLAF BROENDEN
IPC: D06F58/50
Filed: 1991-05-07
Abstract: The clogging of the lint filter of a tumbler dryer with lint and fluff from the laundry being dried causes a reduction of the air transport exceeding that caused by the filling with laundry. This necessitates more frequent regulation of the input temperature (27) to the drum of the tumbler dryer than if the lint filter were clean or totally removed. It is therefore possible to measure the frequency of regulation and compare it to a value obtained by experience gained by drying operations with a clean lint filter. If the frequency of regulation is too high an alarm is triggered, indicating the requirement for cleaning the lint filter. <IMAGE>

Abstract: 1,178,234. Electron beam magnetic deflecting apparatus; printed circuits; coils. ELECTRIC & MUSICAL INDUSTRIES Ltd. 14 Feb., 1967 [26 Feb., 1966; 22 Dec., 1966], Nos. 8555/66 and 57342/66. Headings H1D, H1P and H1R. A printed electrical circuit for use as line and field scanning coils in c.r.t's, particularly vidicon camera tubes for example, comprises a flexible insulating base 1, printed conductors 2, 3 in the form of two similar waves, preferably square waves, extending longitudinally along the base in two portions which may be folded about X-X the resulting strip being wound into cylindrical form to produce a saddle-type scanning coil. The interconnecting conductor portions at at least one end of the waveforms are skewed (Fig. 3, not shown) so as to allow for the differing diameters of inner and outer portions on winding into cylindrical form and so reduce surface wrinkling. An insulating sheet placed between the two portions prior to folding prevents short-circuiting of the overlapping portions. Printed copper register strips 7 with punched locating holes improve accuracy of winding while electrostatic screens. 8 of finely drawn wires reduce eddy currents between the coils.

Title: Improvements in continuous apparatus for the manufacture of superphosphates and similar products
IPC: C05B1/10
Filed: 1940-01-03
Abstract: In making superphosphate fertilizers and similar products (defined below) the mixed reaction materials drop into an annular vat formed by two rotating concentric vertical cylinders 1 and 2 and having a V- or U-shaped bottom with an annular opening 11 provided <PICT:0613410/III/1> <PICT:0613410/III/2> <PICT:0613410/III/3> in the lowest portion.  The slot 11 is closed where there is a risk of the material flowing by a ring 12, having a gap below a rotatry extractor 6 which breaks up the material which falls by gravity through the gap and a funnel 9 to a conveying belt 10. Springs 29 control the pressure of the ring on the edges of the opening 11.  The ring has a concave shape where the mass solidifies so as to reduce friction, or that portion of the ring may be replaced by a stretched metal belt. The ring may also be continuous but eccentric relatively to the general axis so as to leave a discharge opening, or it may be a distortable ring rolling on rollers and distorted at the discharge opening.  The opening may also be provided in the outer vertical wall of a channel 34, Fig. 7, of rectangular cross section below the bottom of a vat and is closed by a band 31 which is displaced by a roller 30 at the discharge point.  An additional extractor may be provided in the channel.  In a modification, the vat is fixed and the extractor is moved around the vat by the ring 12 which rotates. In a further modification, Fig. 24, the vat 1, 2 rotates about a horizontal axis and may have various cross sections the opening being placed either on the outside or the inside of the vat and being closed by a metal belt or other means except at the point of discharge.  The extractor may include an endless belt elevator. The similar products above referred to consist of superphosphate fertilizers mixed with one or more of potassium chloride, ammonium nitrate, ammonium sulphate, ammonium phosphate and if desired, calcium cyanamide and sodium nitrate.

Abstract: 1490882 Acoustic Surface wave devices HAZELTINE CORP 7 Jan 1975 [22 March 1974] 536/75 Heading H3U An acoustic surface wave device comprises two interdigital transducers 11, 26 on a piezoelectric substrate 10, the periodicity D of transducer 11 being a multiple of a length #, and the periodicity B of transducer 26 being a different multiple of # so that the transducers are coupled by surface waves of wavelength #. This arrangement enables devices operating at around 1GHz to be manufactured with finger spacings typical of about 100 MHz. Transducer 11, which has four fingers within its periodicity D, is stated to be coupled to surface waves at its third, ninth and eleventh harmonics, and transducer 26, whose periodicity B contains three fingers, is coupled at its second, seventh and eighth harmonics. In the embodiment shown, D and B are chosen so that the eleventh harmonic of transducer 11 coincides with the eighth harmonic of transducer 26 (Fig. 4, not shown). To increase the bandwidth of the device, the periodicity may vary slightly along the transducers. A conventional transducer (48, Fig. 2, not shown) may be employed, which has two fingers in its periodicity C and which couples to surface waves at its fifth and ninth harmonics. One embodiment envisaged uses the ninth harmonic of transducer 11 and the fifth harmonic of a conventional transducer (48).
