Abstract: The drive shaft (2) of the Venetian blind carries a swivelling apparatus (5) having adjusting strips (6), on which textile support cords (7) arranged in pairs are suspended. By means of loops (7a), the slats (8) are swivellably connected to the support cords (7). Take-up strips (4) lead downwards from the winding-on drums (3) of the drive shaft (2). The pull-up strips (4) and the rear support cords (7) lead to a two-part end rail (9). The two end rail parts (12, 13) are vertically swivellable relative to one another about a hinge joint (14). The rear support cord (7) leads through a cover gap (16) of the end rail upper part (13) and is anchored to the latter. The take-up strip (4) also leads through the cover gap (16), is looped about a web (18) at the end rail lower part (12) and anchored on a web (17) of the end rail upper part (13). Should the rear support cord (7) shrink, it raises the end rail upper part (13) correspondingly. The clearance of the end rail (9) is thereby increased; a raising of the window drip (11) thus does not occur, so that no light gap can form there. The light-tight closing-off of the window by the closed blind is maintained even in the case of shrinking support cords (7). <IMAGE>

Abstract: A method of non-destructive testing wherein ultrasonic signals from a transducer are converted into television wave form and stored on video recording magnetic tape for reproduction as required. Because the signals are recorded live rather than in the form of a cathode ray oscilloscope display they can be rectified as necessary. Positional co-ordinates of the transducer may be stored so that B-scans at varying thresholds can be reproduced. Position and ultrasonic signals are interleaved on the video recording magnetic tape. Apparatus for performing the method includes a video recording device having a rotatable head and interface units for converting the radio frequency signals into television wave form and for decoding the signals for reproduction.

Abstract: A drag conveyor is driven by a reversible electric motor through a torque limiter (18). Each intermediate guide (15A) around which each chain (11A) of the conveyor (10) turns from its lower horizontal run into its upwardly-inclined run is pivotally mounted and is counterweighted against deflection from its normal location. Hence the guide (15A) can be deflected from that location to allow passage past it of solid matter that would otherwise cause jamming. If the conveyor (10) jams even after deflection of the pivotally mounted guide (15A), the torque limiter (18) is adapted to effect automatic reversal of the drag conveyor drive motor to reverse the conveyor (10) for a limited period whereafter normal forwards drive is restored automatically. An alarm is provided which is actuated automatically by a subsequent operation of the torque limiter (18) in response to jamming of the conveyor (10) that was not cleared by reversal of the conveyor (10).

Abstract: An extrusion system for the production of foam boards, billets and the like products includes an extruder (20) at a first higher elevation (22) extruding foamable resin through a die in the upper end of an elongated vacuum chamber in the form of an inclined barometric leg (26) which extends at its lower end into a shallow but large surface area pool (39) of liquid such as water. An elongated shroud or hood (44) on the lower end of the leg reduces the pressure head of water above the foam product as it exits the leg and moves out of the pool for processing at a lower second elevation. The large area of the pool reduces its depth for a given volume and minimizes fluctuations in the level of the pool and the pressure head above the product when the vacuum changes. In one embodiment the pool extends beneath substantially the entire floor of the building (30) enclosing the second lower elevation (31) in which the subsequent processing occurs. In another embodiment the pool extends beneath the leg with the pool also serving as structural footings for the support of the leg and the platform forming the first higher elevation.

Abstract: The invention relates to a solenoid which functions as a bi-directional linear actuator. 
     In one embodiment, the solenoid includes a stator (26) having first and second closed flux-carrying paths defined by first and second cores (26, 40), each having a plurality of concentric cylindrical pole surfaces (32, 34 and 36; 43,44 and 46; respectively) and each defining an air gap (38,48 respectively) between the outermost of the pole surfaces (32,43) and the second outermost of the pole surfaces (34, 44). Coils (50, 52, 54, 56, 58 and 60) are provided for generating electromagnetic flux in the first and second closed flux-carrying paths with the direction of flux flow across the air gaps (38, 48) being substantially radial with respect to the cylindrical pole surfaces. 
     An armature (24) defines a first and a second plurality of concentric cylindrical armature surfaces (73, 74 and 76; 78,80 and 82; respectively). The armature is mounted to be movable in a direction substantially parallel to the pole surfaces with each of the first and second cylindrical armature surfaces overlapping a corresponding one of the concentric cylindrical pole surfaces by an area dependent upon the position of the armature. The area of overlap between the outermost pole surfaces (32, 43) and their respective armature surfaces (73, 78) is substantially equal to the sum of the areas of overlap between the others of the pole surfaces and their respective armature surfaces. The pole surfaces are defined by tapered ring portions of the stator, which portions have non-uniform cross-sectional areas in the direction parallel to the direction of movement of the armature. Similarly, the armature surfaces are defined by tapered ring portions of the armature with the tapered portions having non-uniform cross-sectional areas in a direction parallel to the direction of movement of the armature. 
     A plurality of coils (50, 52 and 54; 56, 58 and 60) are used to generate the electromagnetic flux in the cores (26 and 40 respectively).

IPC: H02K55/04

Abstract: The current lead operates at a cryogenic temperature. The collector ring operates at room temperature. While the rotor is being cooled down there is considerable relative movement between them due to thermal contraction. Electrical connection is ensured by interconnecting "rear" or cold side rods with "front" or warm side rodes. The device of the present invention comprises an insulating connector box (12) mounted on the shaft of the rotor. Inside the connector box there are inner and outer pairs of contact blocks (24,23) which clamp onto both a single rear rod (14) and a pair of front rods (16,18). The clamping force is provided by flyweights (28a,b,c). The rotor may thus be cooled to cryogenic temperatures while stationary or rotating slowly since the rods are loosely clamped if at all, and can slide relative to each other. Once working temperatures are reached the rotor is accelerated and the rods are tightly clamped to provide good electrical contact.

When registering new picture information, a retrieval title to which a delete mark (69) is attached is searched. The length of the picture information recorded at the position represented by this retrieval title is compared with the length of the new picture information to be recorded. If the new picture information to be recorded is shorter, the new picture information is recorded in the deleted picture information area. If the new picture information is longer, another retrieval title with a delete mark (69) attached thereto is searched and the same comparison is made. If all the retrieval titles are searched and there is no retrieval title with a delete mark (69), or if the new picture information is longer than the deleted picture information of the respective retrieval titles with the delete mark (69), the new picture information is recorded in the picture information recording area next to the area which records the final picture information.
