Title: Textile processing - utilises a condensation method to remove obnoxious substances from a discharge to atmos.
Inventor: SCHLEGEL HELGA
IPC: B01D53/00
Filed: 1991-03-02
Abstract: Process separates detrimental substances from the hot exhaust fumes of textile processing by means of condensation. In textile processing, such as scouring, sizing, dyeing, printing drying, there is heat involved, with release of air of chemically laden steam and air. This is extracted along the ducting into the fan, so that the extn. is delayed in the movement through the expansion chamber, which has a water cooling jacket. The expansion chamber has a fourfold area relative to the inlet, and the condensate is drained into the receptacle. The exhaust ducting is again restricted, to delay the passage in the condensation process. USE - To remove the environmentally harmful content of material, released into the atmos. of pollutants, etc., which are contained in the processing materials used in textile mfr.

Title: False-twist yarn texturiser plant - has reel changeover system with one automatic service unit and operator warning devices to maintain maximum efficiency
Inventor: SUZUKI KAZUYOSHI
IPC: D01H9/04
Filed: 1991-03-15
Abstract: The reel changeover arrangement on a falsetwist yarn texturizer is in respect of several machines. A service unit with  automatic controls selects an area in which the service will have fallen behind schedule, and warning lights will give an indication of the situation. USE - Avoids the introduction of a second service unit with complicated controls and a drop in the efficiency level. The operator will only be alerted when necessary, and probably only for a short while, to complete a schedule.
Patent DE-4108662-A1 (DE)
Inventor: JOERG JOSEF DIPL ING DR
IPC: F41A9/16
Filed: 1991-03-16
Abstract: A loading mechanism for guns having a propellant-charge space consists of a loading arm (8), mounted pivotably on the pivot bearing (6) of the barrel, with a loading shell (13) for a projectile (4), and of a feed device engaging on the bottom of the projectile and having a drive, the projectile being capable of being brought by means of the loading arm into an initial position aligned with the core axis of the barrel and being transported into the barrel and rammed into its riflings by means of the feed device. To allow a perfect feed, the loading shell is movable in a guide on the loading arm between the initial position (4') and an advanced position (4'') centred on the barrel, and the feed device has a stay which is contracted in the initial position and engages on the bottom of the projectile and which can be brought, in synchronism with the movement of the loading shell into the advanced position, into an extended position and, in this, can be displaced by means of the drive relative to the loading shell in a guide right into the barrel, with the projectile being accelerated at the same time.

IPC: A47J37/07
Filed: 1991-07-09
Abstract: A grilling device (10) has a bottom tray (12) and side parts (24) fastened to a peripheral edge (20). A container (32) for fuel extends transversely between the side parts (24). Slots (50) are formed in the side parts (24) to receive one or more grilling baskets containing the product to be grilled.

Title: Winding method for heat-treated wire with varying dia. - has central cylindrical wire section pre-curved before coiling, and end sections are coiled elastically
Inventor: FROEHLKE MANFRED DR
IPC: B21F3/02
Filed: 1991-09-03
