Title: Ventilation piping with flexible plastic tube - has rigid framework with axial longitudinal struts and transverse connecting rings
Inventor: HOENMANN WINFRIED DR-ING
IPC: F16L9/00
Filed: 1973-08-24
Abstract: The transparent plastic tube is held open by the rigid framework and partic. by the longitudinal struts around which the tube is placed. A transverse rectangular ring with a flanged end whose plane is at right angles to the frameworks longitudinal axis, is placed over the tube with the four L-shaped struts located in the corners of the ring. The rings are positioned at the ends of the struts so that the flanges can be bolted to those on a neighbouring ring thereby forming a longer run of ventilation piping. Air outlets in the circumference of the tube are bridged by open ended troughs fixed to the framework. The open ends of the troughs lie at right angles to the piping longitudinal axis.

Title: Long length and arc marking out device - secures measurement tape with spring clamp giving reading on grip face side
Inventor: COLLET WERNER
IPC: B25H7/00
Filed: 1973-10-05
Abstract: Device for the accurate marking out of long lengths and arcs which can be used with all types of measurement tapes. When the tape is positioned in the slot of the device, small hand manoeuvres cause a pair of compasses to become operative. Through a grip clamping device comprising a screw with springs and the compass point, the tape is firmly secured. By means of simple pressure on a knob, the tape is released, and after slackening, it is further automatically secured. Every required dimension from zero upwards can be continually adjustable accurately to within a millimetre, and can be read on the face side of the grip.

Title: Continuous production of seam welded and drawn tube - performs forming, welding, pre-sizing and driving in continuous sequence
Inventor: OPPERMANN WILLI
IPC: B21C37/08

Title: Safe disposal system for decomposition gases produced in waste storage - has gas cleaning and drying system and twin pressure containers to maintain constant cycle
IPC: B01D53/34
Filed: 1974-02-22
Abstract: A system for the safe removal and dispersal of gases from decomposing gasbage in gasbage storages takes in gases through a perforated probe tube. The gases then pass through primary separator, drying filter, pump compressor cooler, and are dewatered in condensate separator and dryer before being paned alternately to pressure containers. The pressure containers have contact manometers which artuate relays allowing escape of gas through flash back proof valve gear via a meter to a burner head installation where the gas is burnt. Pressure containers are discharged alternately, thus allowing a contant flow system to operate i.e. one charging, one discharging.

Title: Pebble-bed power reactor - with side reflector cooled in high neutron flux region esp by vertical ducts
Inventor: KOSTRZEWA SIEGFRIED
IPC: G21C15/10
Filed: 1974-03-27
Abstract: A pebble-bed nuclear reactor for high power and high temp. operation, esp. for the prodn. of process heat, has a solid graphite reflector surrounding the pebble-bed; the side wall reflector, near to its inner face and in the region of high neutron flux, comprises cooling ducts. Pref. these ducts are disposed in the vertical gaps between adjacent graphite blocks and are in communication, over at least a portion of their length, with the reactor bed. Below the level of high neutron flux they may taper off and turn in towards the pebble-bed. By the intensified cooling in the region of highest neutron flux, the constraint stresses in the reflector wall are considerably reduced, thus increasing the life of the reflector.

Title: Welding head for seam welding metal sheet - where planetary gear trains force conducting grease to electric contact surfaces
Inventor: MAKAROW MICHAIL D
IPC: B23K11/36
Filed: 1974-04-05
Abstract: Seam resistance welding head for welding metal sheets uses a welding roller mounted on the end of a shaft located in roller-bearings in a housing filled with an electrically-conducting grease and with a device for feeding the grease to the contact surfaces of the shaft. Shells transmit the electric current, the shells being pressed onto the shaft by spring-loaded conductor-straps. The device used to feed the grease consists of >=1 disc with peripheral teeth and fitted with spiral blades. The disc(s) is/are able to rotate on the shaft and is/are driven by a planetary gear which is rotated by a gear-ring with internal teeth fixed to the bore of the housing. The disc gear rotates at a higher speed than the welding roller due to the planetary gear train and thus forces the conducting grease along the contact surfaces, improving conduction and reducing friction.

Title: Plastics moulded curtain rail with inner track - has snap-on plastics front facing panel designed for force-fit over suitably shaped rail
IPC: A47H2/00
Filed: 1974-06-20
Abstract: The curtain track comprises a plastics support rail (11) with a downwardly open track (14) and an integral front piece (18) along its narrow side. This front-piece (18) is provided on either side with outwardly aligned protruding strips (22) which are designed to interact with rigid locking tabs (24) on a front facing panel orfpelmet (12). This facing panel (12) is designed to bend transversely at a certain area (25) so that the tabs can snap over and under the corresponding projections (22) on the rail. Since there is a certain resilience in the facing panel (12) to allow the force-fit connection the demands for precision during manufacture do not have to be so stringent.

Title: Ring hybrid transformer for microwaves - has closed loop containing two-pole networks interacting with line lengths to decouple two outputs
Inventor: RITTER GERHARD DIPL ING
IPC: H01P5/22
Filed: 1974-06-28
Abstract: The ring hybrid transformer, for microwaves, has three or more lines connected to a closed conducting loop and arranged so that the input signal applied to one line is divided between the other two lines. (The two output lines are mutually decoupled). Reactive two-poles are connected to the lines and have reactances that give series resonance for given frequencies that require blocking. The lengths of the lines in the loop and their wave impedances between terminals are chosen so that the decoupling conditions between output lines are fulfilled by interaction with the reactive two-poles. Line segments may have lengths of one eight and one quarter of the wavelength.

Title: Dyeing piled fabric by applying dye powder to the pile - and after hot fixing removing excess powders by eg. washing or suction
Inventor: ZIMMER PETER
IPC: B41F15/42
Filed: 1974-11-13
Abstract: A pile fabric is dyed by applying dye powder onto the pile of the advancing fabric pref. via a mask advancing with the fabric so that dye powder is only applied to selected regions of the pile, and then fixing the dye pref. by passing the fabric beneath a heater. Excess dye powder which has not been fixed is subsequently removed by e.g. washing or suction and pref. the pile is finally brushed up. The method is used for dyeing piles of synthetic, hydrophobic fibres, e.g. polyamide, polyester, polyacrylonitrile, polyurethane, polyolefin, cellulose, triacetate, good quality dyeing is achieved of fibres which are inherently difficult to dye.
