Title: Temp. controlled food container for serving meals - has thermometer readable from outside for accurate monitoring of contents
Inventor: REHAN KLAUS
IPC: A47J41/00
Filed: 1979-09-10
Abstract: The interior of the container is defined by an insulated base and insulated lid.

Title: Prepn. of vinyl chloride from 1,2-di:chloroethane - by thermal decomposition, with cooling of effluent gas in three stages
Inventor: KRUMBOECK REINHARD
IPC: C07C17/25
Filed: 1980-04-03
Abstract: Parent patent described the prepn. of vinyl chloride by thermal decomposition of 1,2-dichloroethane, where the effluent gas mixt. leaving the reactor is cooled indirectly by a liq. or gaseous coolant, and is then sepd. by distn. Cooling is in at least 2 stages, at an average rate per second of 1/10 of the temp., the deg. C, of entry into the indirect cooling zone, until the temp. is 220-120 deg. C. The heat given up to the coolant is used to heat the appts., and the decomposition gas mixt., opt. with a liq. condensate formed from it, is cooled (in)directly in at least 1 further stage. In this addn., the decomposition gas mixt. is cooled in the following stages: (1) indirect cooling to about 220 deg. C, (2) partly direct and partly indirect cooling to about 140 deg. C, with intermittent addn. of a liq. contg. mainly 1,2-dichloroethane (I), and (3) (in)direct cooling in at least 1 further stage, to the temp. of entry into the column in which HCl is sepd. from the thermal decomposition prods. The efficiency of the process is improved, and the interval between times of shutting down the plant for cleaning is lengthened. Formation of deposits on the walls during stage (2) is prevented or reduced.

Title: Machine producing wire terminals for printed circuits - bends wire and then cuts it to produce right angled ends
Inventor: ROTH PAUL
IPC: B21F1/00
Filed: 1980-06-04
Abstract: The terminals of printed circuits are made from short lengths of wire with each end bent at right angles. The wire is fed intermittently by being pressed against a friction roller (3) by a second roller (11) mounted on a hinged lever (13). The wire is fed over two parallel pins (41,42) and is locally pressed to a U shaped by a punch (20) which passes between the pins. Continued movement of the punch cuts away the base of the U by pressing it against cutting edges (43) and so producing bent over ends on each part of the cut wire.

Title: Degasifying and gasifying liquids, esp. water - with atmospheric and vacuum degassing stages before gasification
Inventor: BERGER MICHAEL DR
IPC: B01F23/70
Filed: 1980-09-04
Abstract: A method of gasifying and also degassing liqs., esp. for oxidising water after other gases have been removed from it, consists of passing the liq. through an open stripping/degassing zone, then through a closed, sub-atmospheric degassing zone, and finally through a gasifying zone. Esp. used for degassing water to remove esp. carbon dioxide and nitrogen before the water is oxidised, for example for drinking purposes or for fish farming etc. The method avoids the need to over-oxidise the water to dispose of gasses contained in it. The first, stripping zone at atmospheric pressure removes predominantly carbon dioxide, while the second, sub-atmospheric degassing zone removes predominantly nitrogen.
