Title: Vorrichtung zum Fördern und/oder Behandeln von heissen Gasen
Inventor: BUCHNER HEINRICH
IPC: C04B2/10
Filed: 1979-07-30
Abstract: Bei thermischen Prozessen, insbesondere beim Brennen oder Sintern von Kalk, Dolomit oder Magnesit ist es zur Erzielung guter Wirkungsgrade häufig notwendig, die Heißgase mit Hilfe thermisch hochbelastbarer Fördervorrichtungen. z. B. Gebläse oder Gebläsemühlen, an bestimmten Stellen der Öfen oder anderen Einrichtungen zum thermischen Behandeln der Güter abzuziehen und an anderen Stellen wieder zurückzuführen. Damit die Fördervorrichtung auch bei Temperaturen zwischen 600° und 1300°C und hohen Druckverhältnissen stabil arbeitet und dabei frei von Ablagerungen des geförderten Gutes oder der Stäube bleibt, ist die Fördervorrichtung als mechanische Vorrichtung ausgebildet und wird zumindest teilweise durch eine Kühlflüssigkeit, insbesondere ein Wärmeträgeröl, das in einem geschlossenen Kühlkreislauf umläuft, gekühlt.

Abstract: A two-piece interlocking insulator (4) suitable for covering a truncated triangular pipe (6), the conforming insulator (4) having a base unit (18), a pair of side walls (20) convergingly extending from the ends of the base unit and terminating with an apex unit (22). The insulator (4) can closely conform to the perimeter of the truncated triangular pipe (6) or, as in another embodiment, to a ceramic fibre blanket (10) located around the perimeter of the pipe (6). Each segment of the insulator has a body (24) and a pair of spaced apart arms (26,28). When the two segments are longitudinally and conformingly aligned around the pipe, they can be urged together to form an interlocking, insulator which remains around the pipe without any other means of support. 
     When two truncated triangular pipes are aligned so that their base members are contiguous, an additional embodiment of the insulator includes a pair of segments each having a double-angle side wall (44), a pair of arms (62) partially integral with and partially spaced apart from the double side wall by corresponding recesses and a void corresponding to the remaining double side wall so that as the two segments are conformingly aligned around the pair of pipes, they can be urged together to form an insulator covering. 
     The insulator can further be used with a truncated triangular pipe having a pair of shoulders (36) extending outwardly from each side of the apex member (16) and having a ceramic fibre blanket (38) located around both side members and the base member of the pipe.

Abstract: In the manufacture of continuous sheets or films of plastics material, especially by calendering, an improved stripping process and apparatus control the degree of residual strain in such sheets and films and increase production rates. In preferred embodiments of the process and apparatus, sheets and films of substantially uniform side-to-side texture are obtained. The apparatus includes, for instance, a bottom-fed "L" calender comprising four rolls (10, 11, 10a, 11a). Stripper rolls (12, 13, 12a) take the sheet or film off the top roll (11 a) of the calender and are spaced from it. Also, between the nip formed by the top calender rolls (10a, 11a) and the nearest roll (12), the sheet or film passes round another stripper roll (15) rotating in the same direction as the top calender roll (11a).

Abstract: A data communications system for asynchronous communication having at least two data transmit/receive terminals (50) wherein the display (42) is periodically updated with new send or receive data. In the receive mode the data is accumulated in a receive buffer (72) for a predetermined time interval and then transferred into a text storage buffer (80) which then activates a display access method (86) to process the stored data and update the display. The display access method (86) then goes into an "idle" mode and waits for the next transfer of data which does not occur until the predetermined time interval has expired. In the transmit mode the send data is transmitted without a delay but the display is updated after the predetermined time interval has expired.

Abstract: A monolithic circuit for a television receiver including an amplifier 1 receiving the r.f. input which passes via filter 2 and mixer 3 also receiving the output from local oscillator 4. The i.f. therefrom passes via filter 5 and i.f. amplifier 6 to the synchronous demodulator formed by filter 9 and mixer 8 whereby the demodulated video information is available for further use. A frequency discriminator formed by mixer 10 and delay 11, tracks any frequency variations to provide feedback control to oscillator 4 to compensate for temperature fluctuation. The elements 5, 9, 11 are fabricated using SAW techniques. The elements 1,3,4,6,8,10 are standard semiconductor configurations. 
     Additional filtering after mixer 3 can be employed to separate the sound channel from the composite video and a further SAW delay line employed to produce the sound channel discriminator.

Filed: 1983-12-21
Abstract: A conveyor belt composed of interconnected identical modules of integral plastic molded construction. Each of the modules includes a multiplicity of elongated parallel spaced link elements terminating in respective link ends and an intermediate section between the link ends of grid-like structure. The link ends each include a generally cylindrical projection which extends from one side of each of the link elements along the pivotal axis of the module. The projections extend from the same facing side of each link element. The modules are linked together with each module rotated 180° with respect to adjacent modules such that the projections of each adjacent module extend in opposite directions. The flat sides of the linked ends of mated modules are in engagement to provide only a very small offset in the line of pull through the adjacent link elements to minimize bending forces in the links and link ends.

Abstract: An improved mainshaft gear retainer assembly (66, 68) for a twin countershaft (18, 18A) transmission (10) having at least one pair of floating mainshaft gears (44-46, 48-50) positioned close together in groups of two and clutchable to a mainshaft (40) one at a time by positive clutches (54, 56, 58) is provided. The improved mainshaft gear retainer assembly prevents axial movement of the two closely positioned gears and reacts the axial forces an a clutched one of the mainshaft gears toward and away from the other mainshaft gear to the mainshaft by means of thrust surfaces (78, 124, 126, 128, 130, 132, 134, 136) which are all rotating, or tending to rotate, at the same speed as the clutched mainshaft gear and the mainshaft. The gear retainer comprises relatively simple components and allows easy assembly and disassembly of the mainshaft gears and gear retainers from the mainshaft. Each of the closely spaced mainshaft gears and associated retainer components defines a subassembly (44, 86 and 100 and 46,92 and 104) which is independently assembled to and removed from the mainshaft assembly (20).
