Patent DE-3925343-A1 (DE)
Title: Treating hot brewery plant emissions - by condensn. and cyclone separator followed by adsorption
Inventor: WOLFSEDER ALFONS
IPC: C12C13/06
Filed: 1989-07-31
Abstract: The gas stream from a brewing pan or mash pan contg. water vapour charged with strong-smelling materials, is drawn by a fan into a counter flow coating condenser, and emerges at about 92 deg. C. in the form of a mist. with hop oil and other strong smelling components largely gasified. A jet-stream pump blows the mist. tangentially into a cyclone wherein the heavier liq. fraction is taken downwards to a collector tank for further treatment. Sepd. gas rises in an axial pipe to a chamber contg. adsorbent, e.g. active carbon, for strong smelling components. The adsorbent is regenerated in known manner, and may operate in parallel with a second adsorber to prevent interruption. Purified gas is discharged into the atmos.  or to destroy any residual undersirable cpds. can be taken into the hot fumes produced by a furnace. e.g. the heater for the brewing pan. ADVANTAGE - Strong-smelling materials, whether water-soluble or not, are effectively treated, avoiding atmos. pollution for workers and public.

Title: Magnetic tape player with automatic self-load - uses friction sprung roller device to hold tape in play position
Inventor: WEBER GEORG
IPC: G11B15/675
Filed: 1990-03-26
Abstract: The device consists of two main elements - a moving carriage (9) and a tape holder (15). In the ''play'' position, the tape holder is held in place by a spring (31).

Title: Preventing ozone layer damage from CFC in refrigerator - by securely withdrawing circulating oil and CFC from scrapped refrigerator before sepg. liq. and vapour
Inventor: WEBER JOHANNES
IPC: F25B45/00
Filed: 1990-09-04
Abstract: To avoid escape into the atmos. of the CFC (1) included with oil (2) in the pressurised cooling system of a refrigerator, esp. when the refrigerator is scrapped, the liq. is drained away from the cooling system. The refrigerator is lowered by a crane taking the lowest point of the compressor into engagement with the tip of a drill (4). The drill is enclosed in a jacket (49) maintained at reduced pressure which in combination with the liq. pressure ensures rapid discharge once the compressor wall is penetrated. A feeder (54) transfers discharged liq. to a separator (7) which firstly collects metal chippings and used oil, secondly separates gaseous CFC's and oil, and in a fluid stage separates oil in which CFC's are dissolved. During the final stage a reduced pressure is maintained, causing CFc's to diffuse from the oil. USE - Prevents CFC entering the atmos. and damaging the ozone layer.
