Title: Fermentation method utilising tankers
IPC: C12M1/00
Filed: 1975-11-26
Abstract: 1520130 Fermentation method utilizing tankers REDERI AB SALENIA 26 Nov 1975 [28 Nov 1974] 48617/75 HeadingC6F A method for fermentation of a raw material during transit utilizing a tanker e.g. an oil tanker ship, comprises the steps of chemical sterilization of a storage tank of the tanker, loading a raw material at its source of supply into the storage tank, carrying out controlled fermentation of the raw material in the storage tank to yield a specified fermentation product whilst the tanker is in transit to a point of use or distribution of the fermentation product, and discharging the fermentation product from the storage tank when the tanker has reached the point of use or distribution. The chemical sterilization is preferably effected using betapropiolactone, ethylene oxide or formaldehyde solution. An example relates to the fermentation in the hold of a small coastal tanker, of sugar beet molasses by yeast to produce ethanol. The production of single cell protein from methanol and other fermentations are particularly mentioned.

Abstract: 1,085,257. Aerials. TOKYO KEIKI SEIZOSHO KABUSHIKI KAISHA. Dec. 11, 1964 [Dec. 13, 1963], No. 50532/64. Heading H4A. [Also in Division B5] A spherical dielectric lens reflector (Fig. 1, not shown) of outside radius R, in which the relative permittivity K at radius r.R approximates to (2 - r)/r, has a ceramic core of high relative permittivity, an intermediate shell made of layers containing graduated amounts of high relative permittivity material, and an outer shell made of layers of foamed plastics material, each layer in the lens being self-bonded to the next adjacent inner layer. As described. in a lens intended for 3 cm. waves, an inner ceramic core of radius 1À6 mm. is compounded with titanium dioxide (TiO 2 ) and has a K=83À4. On this is baked a ceramic layer also containing TiO 2 , its K being 43À7 and radius. 5 mm. The intermediate shell comprises ten layers containing various proportions of TiO 2  grains so that K varies from 12À6 for the innermost to 2À02 for the outermost. The outer shell comprises three layers of foamed polystyrene, with K values 1À69, 1À42, 1À14, respectively, the outer diameter being 64 mm. It is stated that a lens acts as an omni-directional reflector with a loss which is nearly uniform in azimuth (Fig. 7, not shown). In a method of manufacture, a spherical ceramic inner core, comprising a centre (9), Fig. 4 (not shown), and a concentric layer (10), is centred in a hemispherical mould (8), of inner diameter coresponding to the outer diameter of the inner layer (11) of the intermediate shell. Material for the layer is mixed with a binder, such as polyvinyl acetate suspended in a suitable volatile liquid, and is packed into the space between the mould and the core. A vinyl parting sheet may be used to prevent the mixture adhering to the mould. The binder is hardened, heat being applied if necessary and the assembly is removed from the mould, leaving a finished half-layer adhering to the core. Other half layers are added successively, using hemispherical moulds of increasing sizes, until the outermost layer is reached (Fig. 5, not shown). The same steps are then repeated to form the second half layers in succession, each second half layer being secured to the corresponding first half layer, to form a complete sphere. In an alternative method of manufacture, Figs. 6A, 6B (not shown), each layer is completed before commencing the next. A lower half layer is formed as before using a hemispherical mould (21) on the lower part of the previously formed spherical portion (20). A similar half layer is formed between two hemi-spherical moulds (22), (23) and is then fitted on the upper part of the spherical portion (20) to mate with the lower half layer already in position. It is stated that part-spherical moulds other than hemi-spherical may be used or fully spherical moulds.
