Title: Tubular ozone generator e.g. for water sterilisation plants - has cylindrical, helically grooved core located inside inner electrode
Inventor: GNEUPEL ARTHUR
IPC: C01B13/11
Filed: 1976-02-19
Abstract: A tubular ozone generator has a hollow cylindrical inner electrode surrounded by a co-axial outer electrode and sepd. from the outer electrode by a tube of dielectric material. A cylindrical core is located inside the inner electrode. One or more grooves extend helically along the surface of the core in the direction of its axis. The grooves are formed in that surface of the core facing the inner surface of the inner electrode and act as flow passages for the medium to be ozonised and for the ozone generated. The ozone generator has a high output relative to its cost. The core presses the inner electrode against the dielectric tube ensuring dimensional uniformity. This enables a no. of ozone generators to operate efficiently in parallel. The high intensity corona is not disturbed by arcing.

Title: Double sealed flat bottomed bag - has flaps sealed to each other and bottom after pressing bag flat
Inventor: HANSON VIOLET M
IPC: B65D30/18
Filed: 1976-03-20
Abstract: The double-sealed, flat-bottomed bag has a seam joining together the sidewalls which are folded inwards (16, 18) towards each other to form the bottom. These folded portions automatically form flaps (40), one above the other, with the closed bottom when the bag is pressed flat. The overlapping flaps are secured to each other and to the bottom and sealed by further seams (44) after they have been pressed flat. These seams can be arranged to secure them together in a direction across the flaps. There can alternatively be folds in the flaps adjacent to the sealed bottom. These folds are sealed to the bottom.

Title: Sterile sealed container vessel - has cap with pipette whose wall acts as sealing surface and grooved cylindrical ring
Inventor: WEILER HERBERT DR
IPC: B01L3/02
Filed: 1976-05-11
Abstract: The sterile sealed vessel (1) has a sealing cap with head plate (8) and pipette (6) and suction bulb (7) for the pipette. The pipette wall acts as a sealing surface, and joins onto a hollow cylindrical ring (11) whose vertical wall has on the inside a peripheral groove (10), below which it tapers outwards and downwards. The two parts of the cap are joined together by tear-off strips (9). There is a double-conical ring (2) on the vessel head, forming a guarantee seal with the cap, while the vessel shoulder is shaped to give ideal stress concentration. The design avoids the need for an additional sealing cap, since the cap is entirely in one piece.

Title: Automatic transmission for heavy vehicle - with fluid clutch and sensors to control gear change without synchronisation
Inventor: BURNETT STANLEY FREDERICK
IPC: B60W10/10
Filed: 1976-05-21
Abstract: The automatic transmission is designed for heavy vehicles and uses a simple, economic layout without expensive synchronisation on each gear. A simple gear box is separated from the drive by a fluid clutch and the input and output drives from the gear box are monitored by sensors which are coupled to the gear change control. The gear change conditions are controlled w.r.t. vehicle speed and torque demands. The throttle setting is controlled during the gear change, so that it is blocked when changing up to allow the control to synchronise the next gear setting.

Title: Recovering large crystals of pure ammonium sulphate - from caprolactam synthesis, by neutralising, removing lactam and evapn.
Inventor: NEUBAUER GERALD DIPL CHEM DR
IPC: C07D201/16
Filed: 1976-11-10
Abstract: Recovery of large crystals of pure ammonium sulphate (I) from reaction mixts. obtd. by Beckmann rearrangement of cyclohexanone oxime (II) in H2SO4 or oleum to give caprolactam (III) comprises first neutralising the mixt. with NH3 at autogenous pressure and 80-125 degrees C. The crude lactam is sepd. and the residual soln. evapd. at 200-600 mm Hg, with cooling to 72-101 degrees C to crystallise (I). The crystals formed are sepd. and the mother liquor recycled to neutralisation. The concn. of (I) in the recycled mother liquor is insufficient to cause crystallisation during neutralisation. Pref. neutralisation is to pH 4.5-5, and the vapours from evaporation can be condensed and used to dilute the mother liquor. Alternatively they are used to concentrate either the hydroxylammonium sulphate solns. used to make (II) from cyclohexanone, or the (I) solns. obtd. by neutralising the oximation reaction mixt. (I) is a fertiliser. It is obtd. as larger crystals than in other processes, and these have lower moisture and esp. caprolactam contents. Utilisation of steam from the evaporator improves heat economy.

Title: Washing drying shield with hinging frame - has rope passed between clamping lever and abutment on sliding sleeve
Inventor: JOGGERST KARL
IPC: D06F57/04
Filed: 1976-12-21
Abstract: The washing drying shield has a standpipe on which are mounted two sleeves on which the frame bars hinge. The lower sleeve is slid upwards by means of a rope reeved round a pulley on it, and prevented from downward movement by a locking mechanism with a clamping lever, which can be released by hand for lowering. The rope passes between the clamping lever and an abutment on the lower sleeve, and is gripped between them. The abutment can be closed to the top end of the sleeve, and the pulley close to the bottom end. The design allows the rope, which is the part most subject to wear, to be easily replaced when necessary.

Title: Isostatic compaction vessel housing two liquids - constituting primary and secondary pressurisation agents separated by flexible diaphragm (SW 16.5.77)
Inventor: TROLLE STEN
IPC: B30B11/00
Filed: 1976-12-29
Abstract: Isostatic compaction appts. for pulverulent material comprises a pressure vessel which contains two liquids separated by a flexible partition. The material is housed in a container which is supported in a deformable container in the vessel. The deformable container is in contact with one liquid which may be pressurised, via the flexible partition, by the other liquid which constitutes the primary pressurisation agent. The partition contacts the deformable container upon pressurisation of the liq. to compact the material and containers. Used in high pressure powder compaction techniques. Provision of a deformable container permits contact with the flexible partition without damaging the latter. The increased deformation capability of the deformable container results in a reduction in the overall size of the pressure vessel with respect to apparatus that utilizes only a single liquid pressurizing medium.

Title: IC engine ignition system with electronics in primary coil - has transmitter controlled switch determining closing time below and above threshold
Inventor: GRAETHER GUENTER
IPC: F02P3/045
Filed: 1977-03-12
Abstract: An ignition system is used for I.C. engines. It consists of an ignition coil whose primary circuit contains an electronic switch and whose secondary circuit contains a spark gap. There is a signal transmitter connected to a rotating shaft indicative of the engine speed. There are two control circuits (17, 19, 22, 14) which determined the closing time of the electronic switch (14) which are driven from the transmitter (10). Actuation will be a function of speed which is obtained from a speed monitoring stage (29, 30, 33, 34). The first device controlled by the transmitter determines the closing time below a speed threshold by measuring the current flow in the primary circuit of the ignition coil (15) up to a limiting value. The circuit controlling the closing time above a speed threshold incorporates a timing circuit (26).
