Title: Self cleaning air filter - having both shaking and simultaneous backflush on cycle timer
Inventor: KOEPFER EDUARD
IPC: B01D46/00
Filed: 1973-01-31
Abstract: The filter contains a >=2 modules having envelope type bags suspended from above. The bags are mounted on a vibratable beam, being held in rubber seals. A flap valve allows the clean air chamber to be mounted either to a suction source for extracting the dirty air from a housing or enclosure, or to a press source for back flushing the bags. during the back flushing cycle, air from the pressure source flows back through the bags as they are vibrated, giving a thorough cleaning to the bags.

Title: Friction butt welding of tubes - by revolving ring between butt ends under pressure
Inventor: TERAI KIYOSHI
IPC: B23K20/12
Filed: 1973-06-07
Abstract: Pipes of large dia. for pipelines are butt welded together by rotating a V-shaped ring which fits in the V-gap of the chamfered pipe ends. When the frictional heat has softened the metal near the ends, an axial force is exerted to weld the pipe ends together and the press the ring outwards. The heavy pipes need not be revolved, only the small ring which can be stopped quickly when desired. This method produces much less internal flash on the pipes than if the pipes are rotated.

Title: Roller for cleaning and moisturizing folding cylinders - transfers anti-static fluid to first cylinder of folding mechanism
Inventor: LANGHAMMER RUDOLF
IPC: B41F35/00
Filed: 1973-06-28
Abstract: The cleaning roller has a cylindrical metal core which is covered by a rigid but porous material to form a liquid reservoir. The roller skin is an elastic and moisture absorbing layer. Two pivot pins located in adjustable bearing blocks, carry the roller in such a way that its whole length is in contact with the first folding cylinder. It is rotated by this cylinder through friction but since it is slowed down by a brake, the circumferential speed of the two elements is unequal. Anti-static fluid from the cleaning roller reaches all the folding cylinders since they are all in contact. Replenishing the fluid reservoir can be done with the machine in operation, whilst the replacement of the saturated cleaning roller can easily be carried out between shifts.

Title: Proteins etc. one step purificn. - by biospecific adsorption and desorption on ultrafiltration membranes
Inventor: REINER ROLAND H DR
IPC: C08H1/00
Filed: 1973-08-02
Abstract: In the purificn of proteins or other biospecifically adsorbable substances by biospecific adsorption and desorption, the adsorption is effected on ultrafiltration membranes. The adsorption is pref. effected by means of biospecifically adsorbing gps. (affinors) which are covalently bound to the crude prod-side surface of the ultrafiltration membrane, while desorption of the biospecifically adsorbed prod. is pref. effected by reversed flow to the desorbant. The procedure enables ultrafiltration and affinity chromatography to be carried out in a single step, and the use of reverse flow desorption permits desorption to be carried out under relatively mild conditions.

Title: Feeding railway lines to machine tools - rollers underneath rails transport them and laterally disposed clamps secure
Inventor: GELINECK WERNER
IPC: B23Q7/05
Filed: 1974-01-15

Title: Rotary piston engine of Epitrochoid design - gas by pass from leading to following chamber is regulated by depression dependent plunger
Inventor: HOHENBERG GUENTER DIPL ING
IPC: F02B53/02
Filed: 1974-03-29
Abstract: A bypass is formed in the inner engine casing between the compression and working chambers just before the shortest axis and near the spark plug. The bypass is formed by a bore containing a regulator plunger, which on medium and high engine load is moved towards the rotor and so is able to close the bypass. Burnt gases from the working (or expansion chamber are able to flow via the bypass at low load and collect around the spark plug points to prevent an ignition taking place, where upon an equal pressure will exist in both compression and expansion chambers. The bypass plunger bore is of greater diameter than the thickness of the rotor sealing strip.

Title: Transmission system static converter control - has rectifier and inverter units grouped in separate halves
Inventor: KANNGIESSER KARL-WERNER
IPC: H02H7/26
Filed: 1974-04-17
Abstract: The control method is intended for the static converter units of a high speed transmission system which has its rectifiers and inverters located in different halves of the system, both converter groups being connected to a common earth. One group is associated with the negative transmission line, the other being associated with the positive one. In the event of protective units in one half responding with subsequent load fall-off in this faulty half, the sound half is controlled by the rectifier and inverter engaged in such a way that any voltage increase at the three-phase current busbar of a static converter unit is reduced or completely inhibited.

Title: HF coaxial cable with seam welded outer sheath - and solid insulation having expansion grooves, allows relief of pressure on sheath
Inventor: WEHDE HERBERT
IPC: H01P3/06
Filed: 1974-05-02
Abstract: The central conductor (1) is surrounded by solid insulation (2), for example polyethylene, and the outer conductor or sheath (3) is made from strip material, typically copper or aluminium, wrapped round and welded (4) longitudinally in the manner of a welded seam pipe. The sheath fits closely over the insulation to maintain concentricity and to prevent collapse of the sheath when bending the cable. To allow for the expansion of the solid dielectric when the temperature rises axial grooves (5) are formed in the outer insulation surface. The insulation expands into these grooves and thus does not stress or burst the sheath. The grooves may run along the cable in a slow spiral.
Patent DE-2422420-A1 (DE)
Title: Flange coupling seal for fluid systems - flange interface is sealed by elastomer ring, axially pre-loaded, and radially deformed
Inventor: HUBER ERICH DIPL ING
IPC: B60D1/62
Filed: 1974-05-09
Abstract: A pressure tight coupling seal for fluid systems utilises a combination of axial preloading and controlled seal deformation in the radial direction. In the instance where a fluid passage (13) cross an interface seal is necessary. The preformed elastomer seal (16) is retained by a tapered outer diameter in a rigid sleeve (14) mounted in one of the component blocks. The axial dimensions of the sleeve and its location are chosen, so that when the interfaces (9, 10) are in contact a preload is applied axially to the seal. When fluid pressure is applied in the bore, the seal deforms radially to ensure firm contact against the tapered bore of the sleeve. The deformation is greatest in the mid-region which has the narrowest cross section (16).
