Title: Gas-blast power circuitbreaker
Inventor: KNUTH WOLFGANG DIPL ING
IPC: H01H33/70
Filed: 1981-07-10
Abstract: In the case of a gas-blast power circuitbreaker, two stationary switching elements are covered, in the switched-on position, by a moving bridging switching movement (6) which is common to both. The device allocated to this contact system for producing an extinguishing gas flow (7) has in its flow path an actuating element which responds to the current flowing via the contact system (3, 4, 6). This actuating element reduces the extinguishing gas flow at low currents, in comparison with that at large currents. According to the invention, the actuating element is formed by the moving bridging switching element (6) whose contact fingers (11) are supported in a spring-loaded manner on a sleeve (6a) which is perforated on the outside, the contact fingers (11) being pressed, in the switched-on position, against the switching elements (3, 4) which are constructed to be hollow, in the form of a nozzle, and stationary, and moving in an arrangement which is distributed uniformly over the inner sleeve circumference with intermediate space (interspace) (Z) in such a manner that the intermediate space (Z) is reduced in size in the case of increasing currents. <IMAGE>

Title: Closure body and method for its production
Inventor: HEINKE JOACHIM DR ING
IPC: A61F2/01
Filed: 1982-02-02
Abstract: The invention relates to a closure body suitable for internal closure of tubular hollow profiles, especially for the intra-arterial and intravenous closure of blood vessels, and to a method for its production. It is the object of the invention to eliminate the disadvantages of known technical solutions and to provide a closure body which can be employed without open and expensive operating techniques. It is the underlying object to provide a closure body for internal use from a material suitable for implantation purposes and a method for its production. The object is achieved in that a helically-wound wire is formed to give a helical spring body by using relatively high degrees of deformation in such a way that the body can be elastically deformed to give a straight helically-wound wire by application of an external force and assumes a nodular shape when the force is partially cancelled.
Patent DE-3217398-A1 (DE)
Title: Suction conveying unit for the pneumatic transport of bulk material, in particular in the unloading of ships
IPC: B65G53/24
Filed: 1982-05-08
Abstract: In the horizontal piping section (13a, 13b) of the conveying pipeline of this suction conveying unit, the piping cross-section is widened in the direction of flow in such a way that the pressure increases along the conveying distance in the piping section, and the reduction in the flow rate accompanying the pressure increase brings about a pre-separation of conveying air and bulk material before the inlet into the separator (6). This pre-separation, which is to start as close to the inlet of the piping section (13a, 13b) as possible, brings about a reduction in the pressure losses in the horizontal piping section and an increase in the separator efficiency. The horizontal piping section comprises frustoconical (13a) and cylindrical (13b) piping pieces and can be designed as a telescopic pipe and can be connected to the separator (6) via a flexible piping piece (12) having a preferably likewise increasing piping cross-section. The telescopic pipe can be extended by the push device (17, 18) and can be pivoted up and down about a horizontal axis (12) of rotation by a lifting device (19) of the horizontal piping section (13a, 13b) in order to adjust the vertical piping section (15, 15a) to the bulk material (4) to be received. The essential advantages of this conveying unit are lower energy requirement and savings in the separator equipment. <IMAGE>

Patent DE-3239792-A1 (DE)
Title: Television transmission system with integrated transmission of sound signals
Inventor: ZSCHUNKE WILLMUT PROF DR
IPC: H04N7/045
Filed: 1982-10-27
Abstract: In the integrated transmission of television signals, the preemphasis/deemphasis necessary at the input and output of a frequency modulation transmission link in order to maintain the quality of transmitted television pictures impairs the sound quality of the these signals. To avoid this influence, either the preemphasis/deemphasis is switched off during the transmission times of the digital sound signals or compensated for by corresponding networks at the transmitting end and receiving end acting exclusively on the sound signals. In the preferred latter solution, the digital sound signals, before being inserted into the video signal, pass through a sound deemphasis network (8) in the transmitter and the digital sound signals extracted from the composite video/sound signal, before being processed further, pass through a sound preemphasis network (9) in the receiver (2). <IMAGE>

Patent DE-3314597-A1 (DE)
Title: Remote-heating line with a roller bearing
Inventor: STOG WILHELM DIPL ING
IPC: F16L7/00
Filed: 1983-04-22
Abstract: A remote-heating line, which consists of a protective pipe and pipelines located inside it, can be installed over large pipe lengths without major cost since simple pushing or pulling into the already laid protective pipe is possible via cylindrical rollers which are arranged and guided at a distance. There is no need to pass through the protective pipe during the work when the pipeline is being inserted. In the case of relatively small pipelines and, in particular, remote-heating lines which are arranged above ground and are generally laid in steel pipes, spacers are provided in the shape of a star around the pipeline, of which in each case the two lower obliquely positioned spacers are provided with large wheels. In this way, the pipeline can be inserted into the protective pipe without disturbance, to be precise over several 100 metres, without special measures being necessary. <IMAGE>

Patent DE-3330714-A1 (DE)
Title: Adjustable mast track
Inventor: GRANT RICHARD W
IPC: B63B35/79
Filed: 1983-08-25
Abstract: A mast track is mounted on a slide with two axial bearings which run in parallel in lateral grooves on a main rail. The main rail has vertically arranged openings which increase in size at the bottom and have 2-inch centre points and in which locking balls are arranged. The locking balls are engaged in their top active position by means of a contact piece and hold the slide in a predetermined position. The actuation of the operating pedals moves a sliding bar in the rail to align the detent receivers with the rail openings. When the locking balls fall down into the receivers of the sliding bar, the platform is actuated for moving into a new position. When the pedals are actuated, a spring is orientated in such a way that it tends to return the sliding bar into non-alignment of the receivers with the rail openings. The locking balls are pushed out of the receivers up into their top operating position into contact with closing grooves, opening to the bottom, in the slide.
