Patent DE-4334687-A1 (DE)
Title: Furnace installation and method for heat treatment of metal components - with division walls and with three empty stations left between the stations loaded first and last
Inventor: FRIEDRICH KARL-HANS DIPL ING
IPC: F27B9/16
Filed: 1993-10-07
Abstract: The furnace installation consists of a ring-tunnel furnace for high-temperature and/or a low-temperature treatment, with a rotatable hearth divided into segments corresponding to heat treatment stations for reception of charges of components to be heat treated. The segments separated from one another by division walls are individually loadable/unloadable, with incremental rotation of the hearth through the furnace. The division walls (29) have profile openings (30) which basically correspond to the outer profile of a charge (23) undergoing heat treatment. Three empty sections are between the first and last loaded sections. Loading/unloading operations are carried out so that three empty sections are maintained between the first and last loaded sections. The method of heat treating metal components is also claimed. Pref. the charging opening (36) of the furnace (11, 12) are provided with tubes (32) for flame curtains and nozzles for inert gas. The charging openings of a high-temperature furnace (11) and a low-temperature furnace (12) face one another. A central charging mechanism (13) serves both furnaces. In the case of several furnaces arranged in a row, a mobile charging mechanism on rails is provided. In the starting position, the middle one of 3 empty stations is situated opposite the loading opening. The rotatable hearth is rotated one segment backwards. The first empty station is now situated opposite the loading opening and the material to be heat treated is loaded into this first station. The rotatable hearth is rotated 3 segments forwards leaving the first hearth section for unloading opposite the loading opening. After this has been unloaded, the rotating hearth is rotated one segment backwards, giving 3 empty sections near the loading opening with the middle one lying after the loading openings. USE/ADVANTAGE - For heat treatment of metal components in various industries. The installation requires little space, has simple construction, and enables temperature cross-over to be effectively avoided.

Abstract: An apparatus for setting a casement on a frame in an open position includes a positioning stay (530) which can be coupled at one end to a mounting piece (520) on a first of two associated frame pieces of the frame and of the casement by means of a pivot hinge (532) and can be connected by its other end to the second of these associated frame pieces by means of a pivoting and sliding hinge. Between the positioning stay (530) and the mounting piece (520) of the first frame piece, supporting means are provided at a point between the pivot hinge and the pivoting and sliding hinge relative to the length of the positioning axle. The supporting means supports the positioning stay (530) in a pivoted out position corresponding to the vent position of the casement in the sense of preventing the positioning axle (530) from approaching a position of an angle of rest of the positioning axle (530) corresponding to a closed position of the casement. Alternatively or additionally the stay may be locked or secured in the closed position. <IMAGE>

Abstract: A press for dewatering a paper web has two press-rollers (14, 16) that form a pressing slit (12). The first press-roller (14) is fixed in the axial direction at least at one end and is held with its journals (53) on first bearing blocks (19).

The tensioning means (26) allow relative movement of the press-rollers (14, 16) in the axial direction. The second bearing blocks (21a) are fixed in position in relation to the first bearing blocks (19) in order to avoid excessive bending stresses of the tensioning means (26). For that purpose, the rotary bearings (25a) of the second press-roller (16) are designed not to tilt or additional support bearings (27a) are provided.

Title: Synchronisation loss detection for ATM communications network
Inventor: DUMONT DENIS
IPC: H04J3/14
Filed: 1994-09-30
Abstract: Detection of a logical synchronisation loss between a transmitter terminal 2 connected by a digital data channel to a receiver terminal 6, is effected by transmitting a predetermined sequence of transmission code words 25 in a sync channel 29 of the data channel 19. In the receiver a sequence of reception code words identical to the transmission sequence 25 are derived in a counter 66 and compared in a subtractor 68 with the received sequence of code words. In the case of a lack of identity between the transmission code words 25 and reception code words 66, the receiver produces a logical synchronisation loss signal 8 for resynchronising the two terminals. <IMAGE>

Abstract: Die Erfindung betrifft einen Thermosäulen-Strahlungsdetektor, dessen Thermoelemente auf einem aus Silizium bestehenden Chip ausgebildet sind, wobei der Chip mit mikromechanischen Verfahren hergestellt wird, die auch für die Fertigung von integrierten Schaltkreisen verwendet werden. Nach der Erfindung wird von einem ursprünglich relativ dicken, plattenförmigen, aus Silizium bestehenden Chip (1) derart viel Material abgetragen, daß neben einem relativ dicken Rand (2) nur noch ein relativ dünnes, mäander- oder spiralförmig verlaufendes Band (3) bestehen bleibt, welches nur mit seinem einen Ende (13) an den Rand (2) angelenkt ist. Die sogenannten ''kalten'' Thermokontakte sind dabei am Rand (2) des Chips (1) im Bereich des einen Endes (13) des Bandes (3) und die sogenannten ''heißen'' Thermokontakte am anderen, freien Ende (14) des dünnen Bandes (3) angeordnet. Durch den erfindungsgemäßen Aufbau ergibt sich bei gegebener Infrarotstrahlung auch bei einer relativ kleinen Chipfläche noch ein relativ großes thermoelektrisches Signal.

Title: Method and machine for the laying down of underwater pipes and cables
Inventor: SKROEDER CARL PETER
IPC: E02F5/10
Filed: 1982-06-24
Abstract: A method for the laying out of a cable (11) under water is executed in one single cycle of operations: (a) digging of a trench, for example by means of a bucket-type digger (2), (b) laying down of the cable (11) by means of pressing-down elements with rollers (9, 10), and (c) the filling of the trench by means of a conveyor (25) and a discharge shaft (13) which lead the excavated bed material back into the trench on top the cable (11). A machine for the execution of the method has a main chassis (3) and a carriage (29) displaceably mounted hereon, which supports the excavation, the laying-down and the filling-in elements. Both the main chassis (3) and the carriage (29) have upwardly and downwardly movable legs (5 and 4 respectively), and by suitable control of the upwards and downwards movement of the legs and the mutual displacement of the chassis (3) and the carriage (29), the whole machine can be made to "walk" along the sea bed (1). In one form of embodiment (not shown) the machine is arranged to deposit a concrete pipe on the bottom of the trench by means of a sliding extrusion mould. The machine can operate submerged as shown and is controlled via a remote-control cable or, in the embodiment not shown, can be provided with a cabin with control arrangements and possibly a drive engine and other equipment. In the event of an interruption in the moulding operation, a tapered end is produced which locks the "old" length of pipe together with the length which is moulded later.
