Title: Sulphur modified polychloroprene prodn. - by copolymerising chloroprene and sulphur in aq. emulsion in the presence of a sec. or tert. amine and tetra:ethyl-thiuram di:sulphide
Inventor: PETTELKAU HANS-JUERGEN DR
IPC: C08F2/24
Filed: 1976-10-12
Abstract: Sulphur-modified polychloroprene is made by copolymerising chloroprene (opt. with up to 20% copolymerisable mono-or di-vinyl cpds.) with sulphur in aq. alkaline emulsion in the presence of known radical initiators, with the addn. of 0.01-1.0wt.% of sec. and/or tert.aliphatic 2-18C amines with straight, branched or cyclic alkyl chains to the polymerisable monomer. The polymerisation is carried out in the presence of an emulsifier system consisting of (a) 3.0-6.0 pts. wt. per 100 pts. wt. monomer of an alkali salt of disproportionated abietic acid, or (b) a mixt. of 1.0-4.0 pts. wt. of an alkali salt of disproportionated abietic acid and 0.4-40 pts. wt. alkali salts of 6-25C (un) satd. fatty acids per 100 pts. wt. monomer, or (c) 0.05-1.0 pts. wt. 8-20C (un)satd., (un)-branched alkyl sulphates and/or alkyl sulphonates and/or condensn. prods. of arylsulphonic acids and formaldehyde per 100 pts. wt. monomer. The polymerisation is also carried out in the presence of tetraethyltriuramdisulphide (I), either added tothe polymerisation mixt. after a monomer conversion of >=5% and is not > 25%, or added to the polymerisation mixt. before the commencement of polymerisation, in an amt. of 0.05-0.4 pts. wt. Process allows single-stage prodn. of polychloroprene modified by sulphur with stable viscosity properties, without the need for a separate peptisation sage as with prior art processes.

Title: DC electric field as rheumatism cure and air purifier - is applied evenly to front of body, or close to floor respectively, using adjustable length electrode
Inventor: PICKEL HANS
IPC: A61N1/10
Filed: 1976-11-08
Abstract: The field is to be applied with an extensible rod electrode held on a stand, to the front of the body (this avoids the ill effects of electric fields on the spinal cord). The electrode is extended to approximately the length of the user's body, giving a uniform field which denies infections the chance to migrate to less electrified areas. For cleaning the air, the electrode is placed about 30cm above the floor, so that germs are drawn down, and not encouraged to float in the air, as they would be e.g. by electrodes at ceiling level. The air cleaning may take place behind a screen, e.g. of lead. Pref the electrode has a strip, cylindrical, tubular, or spiral shape which can be made variable in length.

Title: Swimming shoe with fin hinged to side of sole - useful when swimming breast stroke has extension on fin to angle fin
Inventor: EICHLER DIETER
IPC: A63B31/14
Filed: 1976-12-23
Abstract: A swimming shoe has a sole (4) with an upper (15). A flap or fin (6) is attached to the edge of the sole (4) with a hinge pin (11). The flap (6) has a flexible extension (14) which abuts against the side of the upper (15) and holds the flap at an angle beta in its free position. The flaps (6) are hinged on the outer sides of the shoes so that as the swimmer brings his feet together when swimming breast stroke the angle beta increases to rather more than 90 deg. This effect increases the power of the stroke. The shoe is partic. useful for breast stroke swimmers and helps to correct faulty movements when swimming.

Title: Acoustic room alarm system - senses predetermined sounds and telephones alarm if they persist beyond certain time
IPC: H04M11/04
Filed: 1977-05-26
Abstract: An acoustic monitoring device has a microphone which responds to predetermined frequencies such as the breaking of glass, shutting of doors, or children's crying which may be selected by push buttons. By means of an electronic circuit, it generates a signal which is fed to a variable delay device. If the signal ceases within a predetermined time the device must be reset by a push button. If the signal persists, an automatic dialling device calls up a predetermined number such as the police or fire brigade. An internal amplifier within the device transmits the sensed acoustic signal to the called number by means of a loudspeaker.

Title: Electron-beam tube used as travelling-field tube - has collector electrode and cooling jacket, the gap between packed with elastomer contg. filler
Inventor: BENDIG HANS
IPC: H01J23/033
Filed: 1978-03-22
Abstract: Cathode-ray tube has a collector electrode mounted within a cooling jacket that is electrically insulated from the electrode.

Inventor: JAGGARD JAMES F R DIPL CHEM DR
IPC: C08F2/38
Filed: 1978-09-25
Abstract: The process involves stopping and restarting the homo- or co-polymerisation 2-6C alpha-monoolefins at 40-120 degrees C. and 1-100 bar using a Ziegler-Natta catalyst of (a) a TiCl3 cocrystallisate of the formula TiCl3.nAlCl3 (in which n = 0.31-0.35), opt. modified with an electron donor, and (b) an Al cpd. of the formula R2AlX (in which R is 1-6C alkyl; X is Cl or R) in an (a):(b) molar ratio of 1:1-100.

Title: Digestibility measurements in biological sewage treatment - in aeration and reclarification cylinder with air lift pump
Inventor: MOLITOR ALOIS
IPC: C02F3/00
Filed: 1979-01-27
Abstract: Appliance to supply information on the digestibility of sewage by biological treatment systems consists of a vertical cylindrical aeration chamber in whicha sample is introduced at the bottom next to a bubble bed. A short pipe in a side wall takes the liq./sludge mixt. to a reclarification cylinder in which it descends in a pipe close to the mouth of a central tube. This central tube acts as an air lift pump so that the mixt. can be recycled several times. The digestibility parameters are measured by conventional instruments. This permits a continuous measuring of these parameters instead of draining both tanks and taking samples from them.

Title: Sterilising packing materials and containers - with aqueous solution containing salts, acid or alkali suitable for raising boiling point
Inventor: BUCHNER NORBERT DR
IPC: B65B55/10
Filed: 1979-01-31
Abstract: Materials which raise the b.pt., are introduced into an aq. soln. and this is raised to a temp. >100 degrees C for the thermal sterilisation of packing materials. The materials are heated by means of the soln. and any residues from it are removed completely before aseptic filling with the goods to be packed takes place.
