Title: A process in filtering yeast or other plant cell material
IPC: C12N1/02
Filed: 1965-07-05
Abstract: In recovering bakers' yeast or other biological cell material from suspension, the suspension is filtered through a filter aid, in which filtration a mixture of the filter aid and filtered yeast is scraped off the bed e.g. from the drum of a rotating suction or pressure filter as a layer 0.25 mm. - 3 mm. thick, so as to expose fresh filtration surface, and the filter aid is separated from the mixture. In order to assist the separation as by sedimentation, centrifugation or filtration, the filter aid preferably has a specific gravity or settling velocity different from that of the yeast.  After the separation, the filter aid is washed and returned to the filter bed, or is dried.  The yeast may be further filtered on a rotating suction or pressure filter with or without any filter aid and then dried by roller- or spray-drying. Suitable preparations of the filter aid range from 0.8 to 8.0% based on the weight of the yeast. Alternatively, the filtered yeast may first be subjected to autolysis, plasmolysis and/or hydrolysis to give a yeast extract in the presence of the filter aid and this resulting mixture centrifuged to separate the filter aid. The filter aid is exemplified by starch, diatomaceous earth, siliceous marl, fullers' earth and specified proprietary products.ALSO:In recovering bakers' yeast or other biological cell material from suspension, the suspension is filtered through a filter aid, in which filtration a mixture of the filter aid and filtered yeast is scraped off the bed e.g. from the drum of a rotating suction or pressure filter as a layer 0.25 mm-3 mm. thick, so as to expose fresh filtration surface, and the filter aid is separated from the mixture.

Title: Improvements in the preparation of seaweed for industrial purposes
IPC: C08B37/12
Filed: 1947-10-24
Abstract: Seaweed stalks for use in the manufacture of alginic acid and foods rich in the minerals contained in seaweed are reduced by initially partially drying the stalks, crushing, cutting into fragments, further substantially drying the fragments, and finally drying the fragments.  The stalks, e.g. those of Laminaria digitata or L. Clustonii, may first be crushed between rollers and then cut by a device which acts transversely on the strips alternately in opposite directions to give fragments about the size of a grain of wheat. These fragments may then be dried in a heated dehydrator to 10-12 per cent moisture and then reduced to a mealy condition in a pulverizing mill or disintegrator.  Reference has been directed by the Comptroller to Specification 621,082.

Patent GB-1583805-A (GB)
Title: Chain drive arrangement incorporating an endless link chain
IPC: F16H7/18
Filed: 1977-07-07
Abstract: The endless link chain of the chain drive is arranged in a chain duct (2) in which the chain joints (4) are guided. In operation, the chain is not tensioned because the length of the chain duct (2) is equal to the nominal length of the chain. As a result, the chain also has the same length at all times irrespective of the unavoidable play in the chain joints, although the chain is stretched in the section in which it runs towards the chain drive and compressed in the section following the drive. In the alternately loaded chain joints (4), the lubricant flows repeatedly between the load-bearing surfaces which have just been relieved. This chain drive can be used with advantage as a newspaper transporter in a newspaper printing machine. <IMAGE>

Filed: 1960-08-19
Abstract: 909,749. Typewriters &c. SIEMENS & HALSKE A.G. Aug. 19, 1960 [Aug. 20, 1959], No. 28782/60. Class 100 (4). [Also in Group XL (b)] A type-printing apparatus of the kind in which the type levers may print two or more characters comprises means for selecting which of the characters on the type lever is printed. The selection is made in accordance with one or more predetermined elements of the received code signal or with the position of a key bar set by the actuation of a key, and results in movement of the platen or the type basket or both. In one embodiment the platen 11 is carried by a carriage 10 which is capable of vertical movement under the action of cams 8, 9. A setting finger 4 is positioned in accordance with the first element of a received code signal and abuts either lever 17 or lever 18. When the carriage 10 is in the low position lever 27 abuts lever 21 of a pair of levers 20, 21 which tend to move to follow the contours of cam 3a. In operation shafts 1, 2 and 3 are continuously rotating. Assuming the various levers to be in the positions shown, as shaft 3 rotates levers 17, 20 and 18, 21 tend to move anticlockwise at the fall of cam 3a but they are prevented from so doing by finger 4 and lever 27 respectively. However, if the first code element has caused finger 4 to abut lever 18 levers 17 and 20 are free to move anti-clockwise, this action moving lever 23 which pulls on a cord 24 and releases a pawl 26. Hence shaft 6 rotates and the carriage rises to its high position. By the time the carriage has been raised levers 17, 20 and pawl 26 will have returned to the normal positions so that shaft 6 no longer rotates. Lever 27 now abuts lever 20 and the carriage will therefore stay in the high position until finger 4 is moved once more to abut lever 17. A substantially similar embodiment, which uses a key bar instead of selector finger 4 is described with reference to Fig. 2 (not shown). The carriage and platen are shown in detail in Fig. 5 (not shown).

Title: Improvements in or relating to the manufacture of cellular polymeric materials
Inventor: GEE ERIC
IPC: C08J9/00
Filed: 1955-10-10
Abstract: A process for the manufacture of blown cellular materials by reaction of polyisocyanates with polyesters, if necessary in the presence of water, is characterized in that an organopolysiloxane is incorporated into the polyester/polyisocyanate reaction mixture from which the cellular material is prepared. Organopolysiloxanes, which can be used are dimethylpolyorganosiloxane fluids and their aqueous emulsions, and chain-stopped dimethylpolyorganosiloxane fluids containing dispersed silica.  It may be diluted for use in a portion of the polyester or in chloroform or castor oil.  The polyesters may be like those employed in the process of Specification 790,420. Suitable catalysts are triethylamine, N,N-dimethylcyclohexylamine, di - (b  - diethylaminoethyl) adipate, N,N - diethylbenzylamine, N - ethylhexamethyleneiminine, N - ethylpiperidine or a -methylbenzyl dimethylamine.  The catalyst may be mixed with the other reactants by a continuous process, e.g. as described in Specification 839,183.  As emulsifying agents there may be present turkey red oil, oleic acid wholly or partially neutralized with diethylamine, cetyltrimethylammonium bromide, cetylpyridinium bromide or oleyl sodium sulphate.  The rate of "blowing" can be controlled by adding organic acids such as benzoic, salicylic or terephthalic or inorganic acids such as phosphoric.  In Example (1) to a mixture of a hydroxypolyester prepared by reacting diethylene glycol, pentaerythritol and adipic acid, dimethylpolyorganosiloxane fluid containing dispersed silica and a blend of toluylene-2,4- and 2,6-diisocyanates there is added a mixture of water, diethylamine oleate and di-(b -diethylaminoethyl) adipate with stirring, yielding a foam. Similar examples illustrate the use of various amounts of silicone oil, and other catalysts, e.g. diethylaminopropionamide or diethylaminopropylacetamide, and other ingredients of the reaction mixture such as castor oil or an ethylene oxide condensate. Specification 553,733 also is referred to.
