Abstract: SCANNER POSITIONING MECHANISM   ABSTRACT OF THE DISCLOSURE A scanner system for use with a nuclear reactor incorporates a plurality of permanent guide tubes secured adjacent respective banks of feeder pipes that conduct liquid coolant from the coolant headers.  A radiation detector assembly includes a scanner carriage tethered by means of a reinforced signal transfer cable to a retraction reel, the carriage being displaceable along a selected scanner tube by compressed air, as the cable is paid-out, leakage of the air past the carriage serving to cool the tube, the carriage and its radiation detector. Retraction of the cable permits positioning of the carriage and radiation detector in predetermined relation relative to a selected one of the feeder pipes, whereby the scanner may be used to obtain a reading of any electromagnetic radiation such as neutron or other radiation from that feeder pipe.  The signal output from the scanner is transferred by way of the retraction cable to a remotely located recording apparatus.  Transfer carriage means located on a track positioned transversely of a plurality of feeder banks permits conveyance of the carriage, its associated detector cable and reel, and the air supply means to a selected guide tube for coupling of the carriage and its associated radiation detection elements thereto.  The system permits ready monitoring of the feeder pipes on an individual basis for radioactive emission detection to indicate the possible presence of defected fuel within the individual fuel channels to which the feeder pipes are connected.

Abstract: ABSTRACT OF THE DISCLOSURE     In a sewing machine for performing twin overedging and seaming in one high-speed operation, specially designed top and bottom variable feed dogs pull the two plies through a three needle stitching area with improved, simplified elements for diverting one ply edge while the other is being overcast.  The upright overcast edge of the top ply passes through a tunnel formed through the top feed dog.  A guide wall attached to the throat plate guides the top edge away from the bottom overedging station.  A guard wall can be attached to the presser foot to keep the turned-up top edge away from the seaming needle.  A fiber optic/pneumatic system controls automatic stop, presser foot/top feed retraction and between-work thread cutter functions.  Alternative front edge guides facilitate feeding the two plies in registration.

Abstract: ABSTRACT     SUBSCRIBER LINE SIGNALLING DEVICE         FOR USE IN A TELECOMMUNICATIONS SYSTEM     The subscriber line signalling device (D) is employed in a digital telecommunications system.  In particular the device (D) is used in a subscriber line interface module and it allows all signalling data to be detected and generated on a per-channel basis.  A microprocessor (A) controls the device which generates and detects cyclically permutable code words on a plurality of traffic channel paths to or from the device.  It is arranged that each generated cyclically permutable code word on any one traffic channel path is synchronously coded with respect to any other traffic channel path.  The device can also be programmed to handle different data rates.  In addition the operational modes of the traffic channels can be controlled giving loopback facilities allowing cyclically permutable code words to be generated and detected from the input and output traffic channels as desired and allow a diagnostic facility to be implemented.

Abstract: Abstract Apparatus for producing mineral fibres from silicate raw materials such as basalt, in particular by blast drawing In the production of bonded mineral fibre wool, binder is injected in the chute (16) onto the fibres, as a result of which there is a tendency for the fibres to adhere to the walls of the chute (16) and to form encrus-tations due to binder becoming cured in the course of time.  To avoid such encrustations, which can cause pro-duction shortfalls, the circumferential walls (18, 20) of the chute are constructed as jacketed walls and are cooled by passing cooling liquid in the hollow space (30) bet-ween the inner and outer surface portions (28, 29).  It has been found, surprisingly, that as a result no solid encrustations can form even over prolonged periods, since temporarily adhering fibres cannot in fact become adhe-sively bonded due to insufficient curing of the binder at the low temperatures, but are continuously removed from the wall again.  In contrast to the permanent clean-ing of the chute walls, for example in the form of rotary walls, not only is the considerable expenditure in terms of investment and maintenance and/or unforeseeable plant shutdowns avoided, but also there is obtained dimension-ally accurate sealing of the circumferential walls (18, 20) of the chute (16), so that there is no occurrence of fibre losses or attraction of unwanted air.

Abstract: METHOD AND TOOL FOR NEUTRON LIFETIME LOGGING                              ABSTRACT A borehole logging tool for neutron lifetime logging of subterranean formations surrounding a borehole includes a pulsed source of fast neutrons and a radiation detector for measuring neutrons returning to the borehole from the irradiated formations surrounding the borehole.  The radiation detector system comprises a neutron absorbing and gamma ray radiating material which is moved by an articulating arm into contact with the borehole wall and is azimuthally oriented so that such neutron adsorbing and gamma ray radiating material is firmly pressed against the formation.  A shielding material minimizes absorption of neutrons from the borehole fluid.  A gamma ray detector located in the main body of the logging tool detects gamma rays from the radiating material as a measure of the epithermal or thermal lifetime characteristic of the formation adjacent the borehole.

Abstract: ABSTRACT     METHOD OF AND APPARATUS FOR FRAME DECODING     In a method of and apparatus for frame decoding, in particular in a multiplexer-demultiplexer system for digital signal transmission, in which a series bit flow (BS) has a frame structure including a periodically occurring item of synchronising information which characterises the start of each frame, a synchronising bit (S) is used as synchronising information. Commencing with the m-th search frame, and the following (m+1)-th search frame - where each search frame has the same number of bits as the frame - a logic AND-link is performed, where the result provides the (m+1)-th search frame for the  next logic-link. It is determined when only one bit, the synchronising bit, in the search frame is set at logic "1" and this setting is retained for a plurality of search frames. A synchronising signal (SS) corresponding to the time position of the synchronising hit is generated and the bit flow and/or the synchronising signal are delayed in such manner that the  synchronising signal and the synchronising bit occur in synchronism.

In  such a circuit arrangement, a mutual control of the subscriber stations occurs via the data bus per se without the assistance of additional control lines.  This is achieved with the assistance of a recognition circuit which emits a free signal at its output given at least approximately identical voltages at the data bus and emits a busy signal given different voltages at the data bus.  The control arrangement is particularly suit-able for utilization in remote control stations.
