Title: Wire extruder for small dia high resistance wire - has hemispherical body recess of radius greater than height of radiused edge
IPC: B21C3/04
Filed: 1976-04-01
Abstract: The extruder body (3) is made of high temperature ceramic material such as that defined in DIN specification 1547. The body is held in a cylindrical housing (2) almost closed by a flange at one end to hold the body securely.

Title: Durable packing process for potable and mineral water - by treatment with ozone and sealing in synthetic material bags
IPC: B65B55/18
Filed: 1976-04-02
Abstract: Durable packing process for potable or mineral water consists in subjecting the water, before packing to a preliminary treatment with pure ozone before enclosure in a leaf-proof package, some 2-5g of ozone are introduced per m3 of water and maintained in contact for 5-15 mins. in a special contact vessel. The treatment is generally sufficient to kill all germs. Excess of ozone is removed in a second recipient by agitation; after degassing it amounts to 0.5 mg per litre and the water is packed under aseptic conditions into synthetic recipients or bags. Any ozone gas released during filling forms a protecting cover and excludes air. The packages are heat-sealed. A long period of preservation is assured with the water in a perfect state as regards bacteria and taste without prejudice to the important constituents of the water. There is no danger of re-infection because a supplementary sterilisation is obtd. by the layer of ozone, liberated during filling, which forms in the package.

Title: Rotating shaft end seals with recirculating flow - has stator and rotor with flushing flow preventing accumulation of dirt
IPC: F16J15/34
Filed: 1977-02-24
Abstract: The end seals for a rotating shaft ensures that dirt particles cannot be collected into the seal pockets. The seal arrangement has a rotor (1) on the rotating shaft (2) and a stator (4) enclosing the shaft. The rotor and stator have circular elements with circular sealing faces which face each other. These seals are used against a first leakage proportion of the sealed pressurised fluid. Long pockets (10, 12) extend along curved paths around the circular sealing faces. Fluid channels (14) are connected to the pockets for allowing a second leakage proportion to flow to the pockets and for facilitating flow of a flushing liq. The flow path of the leakage proportion has lower flow resistance than that for the flushing fluid.

Title: Electrolytic cell with perforated vertical electrodes for gas passage - the free hole area increasing uniformly from bottom to top
IPC: C25B11/03
Filed: 1977-02-28
Abstract: An electrode for the prodn of a gas in an electrolysis cell with vertical electrodes comprises a vertical conductor plate pierced by holeS, the overall open area increasing from bottom to top of the plate. The area distribution across the width of the plate is uniform. Each hole pref has a small projection along its upper edge to direct the gas formed on the active surface of the electrode through the holes. The electrodes can be used in diaphragm cells or cells using a selectively permeable membrane for electrolysing aq. soln. of alkali metal halides or for the prodn. of hydrogen and alkali metal chlorate. The electrode reduces the loss by the joule effect across the electrolyte. It reduces the mechanical influences on the diaphragm or membrane during electrolysis. It makes possible the use of stronger currents and reduces the necessary distance between anode and cathode, which results in an increase in cell prodn. capacity without increasing floor space. The invention allows the overall area of the holes to be reduced relative to the total electrode surface, which increases the cell productivity.

Title: Heat treatment of granular fruit seeds - with precise control of heating rate, temperature and duration (OE 15.9.78)
IPC: A23L5/30
Filed: 1977-05-12
Abstract: Fruit contg. granular seeds is fed via a hopper and regulating feeder into an oven. The fruit passes through the oven on a belt or vibratory transporter and is heated by means of ultra-high frequency electromagnetic waves or infra-red radiation to the desired temp. It then passes through a second chamber in which the temp. is maintained. This chamber is insulated and equipped with sec. heating which may be similar to the heating system in the first chamber, or, as pref. resistance heaters. The treated fruit then passes through a crushing or rolling device into a cooler and thence to storage or subsequent treatment. The best treatment for each type of fruit is predetermined experimentally and then the temp. to which the fruit is heated in the first section is adjusted by varying the intensity of the radiation or by switching it on and off, and the duration of each stage is varied by adjusting the feed rate and length of travel through each section. The system enables the rate of heating, duration of treatment and temp. to be precisely regulated according to the nature of the fruit being treated. The result of this is an improved final content of digestible protein and energy.
