Inventor: GREFFRATH RAINER DR ING
IPC: B01J8/24
Filed: 1990-05-18
Abstract: In a heat exchange appts. in which most of the tubes are riser tubes for a solids-laden medium to be treated and the rest of the tubes are return tubes for fluidised solid particles for supply to an internal circuit, the novelty is that (a) the appts. has a medium entry chamber (1) contg. an internal container (13) which has a central outlet (16) in its base (15) and which can hold the entire fluidised material (10); (b) a gap (14) is formed between the internal container (13) and the housing (7) of the appts.; (c) a medium inlet (2) is located at the side of the entry chamber (1) and is connected to the outlet (16) by a pipe (22) which passes through the sidewall of the internal container (13); and (d) openings (17) are provided around the outlet (16).

Title: Bonding wire directly to contact face - after laser removal of contact face oxide and impurities
Inventor: KRUEGER GUENTHER DR
IPC: H01L21/60
Filed: 1990-06-22
Abstract: (A) In prodn. of a connection between a bond wire (20) and a metallic contact face (12), esp. for circuit board components (pref. discrete or integrated semiconductor devices), the novelty is that the contact face (12) is freed from oxide (13) and other impurities (13@) before bonding the wire (20). Pref. a laser (esp. an excimer laser) is used to remove the oxide and impurities.  (B) Equipment for carrying out the process consists of a commercial bonding device combined with a laser (pref. excimer laser) system.  (C) Also claimed is an electronic assembly (esp. a semiconductor component) produced by the process.  Pref. the laser has a 180-350 (esp. 193) nm. wavelength and is pulse-operated pref. in the nanosec. range. The process is suitable for use in the bonding of aluminium bond wire directly to copper contact faces of unpackaged semiconductor devices. ADVANTAGE - The process allows direct bonding on a metallic contact face of non-precious metal (e.g. Cu or Ni), thus avoiding expensive special metallising e.g. with Au and Ni.

Title: Retractable rudder for sporting boat - is actuated by Bowden cable which passes through hollow rudder shaft
Inventor: PIETSCH JUERGEN
IPC: B63H25/38
Filed: 1990-07-12
Abstract: The boat used for sport is steered by means of a rudder which can be swung about a vertical hollow shaft (12). The ruder blade (16) is mounted on an arm which can swing through 90 deg about a horizontal axis (34) in a bracket (30) which is rigidly attached to the vertical shaft (12). The rudder can thus be swung from its inactive position, when the arm is horizontal, to its active position, when the arm is vertical. The arm is actuated by means of a Bowden cable (20) which pases through the bore of the hollow shaft (12) which supports the rubber. USE - Passing the Bowden cable through the shaft eliminates the risk of the cable fouling the rudder mechanism.

Title: Recovering useful materials from scrap - by passing through heated chamber with different temp. sections, each with own discharge for degassing, condensing, sepn.
Inventor: GREUL ARTUR RICHARD
IPC: C10B57/02
Filed: 1990-08-17
Abstract: Low temp. degassing process is used for disintegrated organic materials e.g. (preferably) used tyres, plastics, scrap electronic gear, or mixts. of the same, the main purpose being the recovery of raw materials. The process uses a hollow screw chamber divided into one or more stages arranged successively and sepd. individually; with one circulating system, for heating agent to provide separate temp. sectors for drying and degassing, and the degassed prod. is discharged from each stage separately; the plant used can have a single or double screw mounted in a jacketed body sealed at the top. The temp. stage of up to 150 deg C is mainly for drying but also to split off water of hygroscopy. In the next stages the first removes complex liq. condensates. Both these stages produce useful material, of which liquids can be up to 90%. The condensate obtd. is mainly aliphatic hydrocarbons and olefins; used for recovering ethylene, propylene and styrene, etc.. ADVANTAGE - Produces large vols. of clean degassed materials at temps. of 150-450 deg C.

Title: Bleaching cellulose material esp. cotton with peracetic acid in acid soln. - without activator to increase whiteness and reduce waste liquor pollution
Inventor: POULAKIS KONSTANTINOS DIPL CHE
IPC: D06L4/15
Filed: 1990-11-05
Abstract: Bleaching cellulosic materials or cellulose, esp. cotton, is carried out with peracetic acid (I) soln. with pH 1-4, without using activators. Pref. bleaching is carried out at pH 2-3.5 and 30-60, esp. 45-55 deg. C for 15-120, esp. 30-60 min.. An aq. soln. contg. 0.5-10, esp. 2-8 (wt.)% (I) is used. Bleaching pref. is accompanied by ultrasonic treatment at 20-50, esp. ca. 35 kHz with a power of 0.2-4, esp.0.5-2 W/cm2. The goods/liquor ratio is ca. 1:8 to 1:50. Bleaching may also be carried out by slop padding with 80-180% pick-up, using liquor contg. 0.05-2% (I), followed by a dwell of 2-8 h at room temp., 15-120 min. at 30-60, esp. 45-55 deg C or 2-15 min. at 80-160 deg. C, pref. in satd. steam. The bleached material is treated in an alkaline liquor, esp. with pH 8-11, and then dyed or treated with alkali and dyed in the same liquor. USE/ADVANTAGE - The deg. of whiteness is much better than that obtd. with (I) at pH 5-7 and no activators, stabilisers, complexing agents or corrosion inhibitors are needed. The spent bleach contains few impurities and has a much higher pH, so that it can easily be neutralised with spent alkaline liquor from cotton finishing, which also decomposes the residual peroxide, with O2 formation
