Patent DE-4117550-A1 (DE)
Title: Plate filter insert - has concertina-folded sheet material where outer edges are held in place against frame to prevent leakage of unfiltered air
Inventor: SCHNEIDER HORST
IPC: B01D29/07
Filed: 1991-05-29
Abstract: In plate filter insert with concertina-folded sheet material gas filter incorporates a sheet of concertina-folded material located within a frame. Strip of material of unalterable length extends over the entire length of one surface of the concertina-folded filter material. Peaks of filter material and the strip with which they are in contact are connected. Strip material and the stiffness of the folds together prevent the strip bending vertical to the filter plane. USE/ADVANTAGE - Arrangement ensures that the filter material is inserted square within the frame so that the outer edges are held in place against the frame to prevent leakage of unfiltered air around the sides to the filtered side. A suitable frame assembly with concertina-folded filter material (3) incorporates a strip (14) of non-extending material on the back (15) of the filter insert. Some of the filter peaks (15) are joined to the strip (14). The stiffness of the folds (16) in a direction vertical to the filter plane ensures that the strip (14) cannot be dislodged. The strip is made of a pliable material and bears a coating on the face in contact with the filter material with which it is joined.

Title: Pneumatically assisted electrically driven aorn feed for plasma spray gun - uses pressurised gas feed to assist passage of transported material over end of worn feed
Inventor: TSIAPRASIS ILIAS
IPC: B65G53/48
Filed: 1991-06-12
Abstract: The unit comprises a worm feed (4), enclosed in a pressure-tight housing (3) with pressurised gas inlet (5) and gas/powder outlet (6) apertures, a variable-speed electric motor (9), positioned within a pressure-tight casing (11), and a powder hopper (1) located on top of a ring-shaped support (7).

Title: Natural pheromone mixts. for use in sheep rearing - enable reproduction to be intensified independent of season and are non-toxic
Inventor: MENGER HORST
IPC: A61K35/36
Filed: 1991-09-04
Abstract: The recovery and prepn. of a zoo-technical agent for use in sheep rearing comprises recovering a natural-biological active ingredient mixt. of aromas specific to the species of animal (i.e. pheromones) by extractively washing out a substrate contg. the pheromones from hair cut from animals of the same sex arranged in the naturally growing direction of the fibres, cleaning the soln. and then sepn. the solvent. The recovery of the substrate contg. the pheromones in its effective condition is carried out by recovering the hair at a characteristic period specific to the species and race. This characteristic period is determined by max values of physiological-biochemical criteria and max. parameter of sexual behaviour of the animals within this period. USE/ADVANTAGE - The pheromones are recovered from living animals and can be made available in their natural composition and in natural amts. at any point in the year, thus enabling the reproduction to be intensified and independent of season after the first insemination and lambing. As the origin of the pheromones is natural and as they are used in natural quantities there is no toxic risk to the animals nor to the workers, nor to those who will consume the animal prods., nor to the environment.
