Filed: 1995-01-23
Abstract: The subject invention provides non-human mammalian hosts characterized by inactivated endogenous Ig loci and functional human Ig loci for response to an immunogen to produce human antibodies or analogs thereof. The hosts are produced by multiple genetic modifications of embryonic cells in conjunction with breeding. Different strategies are employed for recombination of the human loci randomly or at analogous host loci. Chimeric and transgenic mammals, particularly mice, are provided, having stably integrated large, xenogeneic DNA segments. The segments are introduced by fusion with yeast spheroplasts comprising yeast artificial chromosomes (YACs) which include the xenogeneic DNA segments and a selective marker such as HPRT, and embryonic stem cells.

Filed: 1995-12-07
Abstract: The invention concerns a method for treatment of pulp in connection with bleaching. The pulp is first cooked and acid-delignified if necessary to lower its kappa number to below 24, preferably below 14, after which it is treated in an acid stage at a pH of 2-5 in the temperature range of 75-130 degrees Celsius to lower its kappa number by 2-9 units. In order to prevent significant reduction in the strength value of the pulp, the dwell time in the treatment tower of the acid stage is 30-300 minutes and the treatment temperature T degrees Celsius is T subscripts min < T < T subscripts max. The invention also pertains to an apparatus system intended to be employed in the method. <IMAGE>

Patent GB-1286063-A (GB)
Title: Improvements in or relating to the manufacture of high-resistance gallium arsenide
IPC: C30B11/06
Filed: 1970-01-12
Abstract: 1286063 High resistance gallium arsenide SIEMENS AG 12 Jan 1970 [11 Jan 1969] 1355/70 Heading C1A Arsenic vapour is introduced into the synthesis vessel in the manufacture of high resistance gallium arsenide by horizontal two temperature process through a molten layer of boron oxide at a temperature between 600‹ and 750‹ C. The boron oxide layer is between 0À1 and 2 cm. thick or more. The process may be carried out in either open or closed vessels. In the former case an inert carrier gas, e.g. argon, is necessary to conduct arsenic through the boron oxide layer. In an example, 20 gm. of gallium are placed in section A of a synthesis ampoule as shown in Fig. 2 at 28, and the section A is then sealed at 29 under high vacuum, 25 being a frangible diaphragm. Boron trioxide, which has been dried is introduced, to 24, in section B of the synthesis ampoule in the form of small fragments, whilst the stoichiometric quantity of arsenic 23 required to form gallium arsenide is introduced via 22. A and B are fused together at F and the entire volume evacuated up to 25, after which sealing at 22 is carried out. Heating is carried out in a tubular furnace such that sections D and E of the ampoule reach 620‹ C. and then section C is brought to the same temperature. Arsenic vapour diffuses through B 2 O 3 , 34, past staggered baffles 36 and condenses at G in the synthesis ampoule. When all the arsenic has sublimed from 33 to G the ampoule is sealed at 37. The ampoule is heated in a two-temperature furnace so that gallium is at 1250‹ C. and arsenic at 620‹ C. The frangible diaphragm is then broken and arsenic vapour reacts with the gallium to form gallium arsenide which is crystallized by controlled solidification.

Title: Inhibition of perspiration
IPC: C01F7/57
Filed: 1976-01-14
Abstract: To produce a novel composition active as an antiperspirant in the form of an aqueous solution, there is used as the starting material an appropriate solution of a compound of the empirical formula               Al2(OH)6-aXa where X is Cl<->, Br<->, I<-> or NO3<-> and a is a number from 0.3 to 1.5. The said solution has a concentration of the aluminium compound of 7 to 35% by weight and is heated at a temperature of 80 to 140 DEG C for a length of time such as to cause the formation of polymeric species having a particle size of over 100  ANGSTROM  in the said solution. These species then contain at least 2% by weight of the total aluminium. By means of spray-drying of the aqueous solution obtained, the novel composition acting as an antiperspirant is obtained in the form of a solid.

[Also in Group XXV] For coarse and fine adjustment of member 2 relative to a supporting abutment (not shown) against which the corresponding head 7 of a spindle 3 is secured by a clamp 8, an internally and externally-screwed sleeve 1, having similarly handed threads of different pitch, is screwed on to the spindle 3 and into the member 2. For coarse adjustment the abutment clamp 8 is released and the sleeve 1 is clamped relative to the member 2 whilst the spindle 3 is rotated. For fine adjustment the clamp 8 is tightened to hold the spindle 3, the sleeve 1 is unclamped relative to the member 2 and is rotated by a head 4, the distance moved by the member 2 being the product of the difference in the pitches and the number of turns. When the desired position is reached the sleeve, spindle and member 2 are all clamped relative to each other by pinch screws 5 in the members 4, 2.

Filed: 1938-01-17
Abstract: 490,122. Fire-extinguishing liquids. SEAT, J. L. Jan. 17, 1938, No. 1554. [Class 47 (ii)] A fire-extinguishing liquid consists of 15 per cent tetrachlorethylene, 15 per cent cellulose acetate, 29 per cent carbon tetrachloride, 30 per cent dibromdichlorethane, and 11 per cent bromoform. When thrown upon a fire, the liquid generates a heavy, blanketing, and non- toxic, vapour, the cellulose acetate forming a film on the burning materials. The bromoform acts as a freezing point depressant. The tetrachlorethylene is thoroughly mixed with dry cellulose acetate until the latter passes into solution, the carbon tetrachloride is next admixed, then the dibromdichlorethane, and the mixture is strained. Finally, the bromoform is added.

The width of the spray may be adjusted by turning off one or more of the valves and two or more spray bars may be pivotally interconnected by a hinge. By-pass passages may be formed in the housing 12 to ensure that hot asphalt under pressure is always flowing through the recirculation conduit to prevent clogging &c.
