Title: Living room air purifier - has tubular guides discharging below surface of water causing it to flow around circular path
Inventor: WALTER HEINZ-G
IPC: F24F8/40
Filed: 1977-02-12

Title: Decaffeination of green coffee - by aq. extraction, drying, and extraction with organic liquid
Inventor: HUDAK STEPHEN FRANCIS
IPC: A23F5/22
Filed: 1977-05-16
Abstract: Green coffee is decaffeinated by extracting the coffee with an aq. liquid, drying the liq. and extracting the dried solids with a liq. organic solvent. Pref. solvents are methyl, ethyl and propyl alcohols. After sepn., the solvent may be processed to recover noncaffein solids which are then combined with the dried coffee solubles (e.g., by cooling to ppte. coffee solubles and then extracting with a solvent for caffeine). The solvent and caffeine extractant may be the same. The aq. liquid may be (a) water and the decaffeinated dried dolids are reconstituted with water and adsorbed on water extracted green coffee or (b) a caffeine deficient soln. of green coffee solubles and the decaffeinated dried solids are reconstituted with water and the resulting soln. is used to extract caffeine from green coffee. Eliminates the need for the use of halogenated solvents. The aq. soln. is dried, allowing the use of water-miscib-solvents.

Patent DE-2803002-A1 (DE)
Inventor: OW HANS-PETER VON DR
IPC: H04Q3/00
Filed: 1978-01-24
Abstract: In this switching system, devices for detecting errors are provided which utilise plausibility checks, and sporadic errors are signalled after an adjustable threshold is exceeded. In the associated more or less centralised control devices (V1, V2, U1 ... Um), counting devices (Ts1...Tsd; e1, e2; u1...um; ks1...wsx; ...) are contained which are in each case individually allocated to one device which is less centralised than the one in which they are contained in each case. These counting devices count plausibility errors found. The counting devices have adjusting counting limits and supply error signals when these are reached. In the control devices (V1, V2) of the highest degree of centralisation, additional counting devices (V1...) are contained. Error signals supplied by counting devices initiate the inhibiting of devices and possibility their replacement by similar devices. <IMAGE>

Title: Semiconductor device reliability test - by overloading chips through second conductor track plane and removing it for wafer test
Inventor: REINDL KLAUS DIPL ING
IPC: H01L23/58
Filed: 1978-08-02
Abstract: In a reliability test for semiconductor devices, a second conductor track plane is defined to the first and allocated to the chips which remain assembled in the first. The chips receive the temp./voltage overloads via this second plane. The latter is then etched away and the normal wafer test can be carried out for the assembly to determine any parameters which may have been affected by a drift due to the overload test. The result is a great saving in expenditure for testing (20% excess voltage and temp. for 24 hrs.) because the reliability test is carried out when 300-1000 chips are still assembled on a board for simultaneous test.
