Title: Flexible mounting for filter bag - in which the air flow induces vibration to keep filter surface clean
Inventor: ZENNER HERBERT
IPC: B01D46/04
Filed: 1973-03-09
Abstract: The bag is fusioned by an internal spring which rests are >=3 feet positioned inside the mounting collar. The spring has the same diameter at the top and base as the bag, but in the centre has smaller diameter. This allows the bag walls to vibrate in sympathy with the air stream and any dust collected falls back into the receiver below. The device is extremely simple and requires no external cleaning agency and is of particular application for vacuum cleaners.

Title: Variable air stream filtered at constant air speed - through filter varied in area by movable blind
Inventor: SCHILLING KURT
IPC: B01D46/18
Filed: 1973-07-26
Abstract: A method of air filtration, designed to operate with varying air flow rates, consists of modifying the total surface area of the filter exposed to the air stream by partially covering it on the upstream or downstream side. Pref. a portion of the filter area is covered by a flap, a roller blind, roller shutter or the like, and, the rate of opening of the covering is adjusted to the rate of change in the air flow, so that the air speed through the filter itself remains constant. Thus optimum efficiency of filtration is achieved; in particular, sudden changes in speed of air do not occur, which could cause shaking of the filter with consequent agitation of dust already separated from the air.

Patent DE-2346632-A1 (DE)
Title: Injection mould esp. for small precision parts - half moulds are closed by wedging action which considerably reduces required mould locking force
IPC: B29C45/70
Filed: 1973-09-17
Abstract: An injection moulding machine with a two-part mould has driving means for moving the half-moulds together/apart transversely to the parting plane, and means for locking the mould when closed. Each half-mould has two or more surfaces oblique to the parting plane; these surfaces are engaged by corresp. surfaces two on each of at least two clamping jaws. These jaws are driven, to close the mould, in a direction parallel to the parting plane. In a prefd. arrangement, the half-moulds are genrally disc-shaped, with a frustroconical surface around each disc to engage with corresp., female frustroconical surfaces in the jaws. This arrangement can reduces the required value of the mould locking force from e.g. 30 to 1.8 tonnes.

Patent DE-2422083-A1 (DE)
Title: Three-phase excited magnet system - is for stabilising unsupported vehicles having more than two cores across the vehicle track
Inventor: HOCHHAEUSLER PAUL DR ING
IPC: B60L13/10
Filed: 1974-05-02
Abstract: The application is to magnetically levitated and propelled vehicles, and aims to increase the stabilising forces keeping the vehicle wthin the bounds of the track. This is achieved by arranging more than two rows of three limbed open cores across the axial line of the track, for example four lines of magnets. There are thus four parallel lines of travelling fields, and, by arranging the non-magnetic vehicle base in a manner analogous to the hulls of a trimaran the forces tend always to centralise the vehicle over the magnet system. Typically the sides of the non-magnetic hull are tapered inwards towards the base to assist the centralising effect.

Title: Colour coding of individual cable strands - applies paint to each element at separate station and through separate heated tubes
Inventor: MARX KARL-HEINZ
IPC: H01B13/34
Filed: 1974-06-08
Abstract: The system is intended for column coding the individual strands which form a stranded cable. The strands are twisted into cords on a machine and the characteristic coding is introduced simultaneously in the shape of rings around the insulation of the individual cable elements.
