Inventor: VON POELNITZ W
IPC: C12N9/00
Filed: 1960-02-16
Abstract: Enzymes of bacterial origin are isolated from crude solutions containing same by desalting the solution with, for example, an ion exchange material or by dialysis until an electrical conductivity of 600-10,000 and especially 800 to 1,000 ohms is obtained, adjusting the solution to a pH value of from 7 to 11, adsorbing the active substances by means of cellulose containing a basic group, (preferably diethylaminoethyl) and eluting the active substance at a pH value of 2 to 7 by means of a 0.2 to 0.5 molar aqueous salt solution.  The buffer eluates are freed from inorganic ions by dialysis or treatment with ion exchange materials, and then lyophilised.  For the desalting step a mixture of cation exchange based on polystyrene (e.g. Amberlite 1R-120) in H- form and an aromatic anion exchange resin containing quaternary ammonium groups (e.g. Amberlite IRA-410) in OH form may be used.  The buffer salt solution may be a phosphate, acetate, sodium chloride or phosphate sodium chloride buffer solution.  Specified enzymes are streptokinase, streptodornase, bacterial - peptidases, -proteinases, -phosphatases, catalases, -hemolysins and coagulase.ALSO:Toxins and toxoids of bacterial origin are isolated from crude solutions containing same, especially culture solutions, by desalting the solution with, for example, an ion-exchange material or by dialysis until an electrical conductivity of 600 to 10,000 and especially 800 to 1000 ohms is obtained, adjusting the solution to a pH value of from 7 to 11, adsorbing the active substance by means of cellulose containing a basic group, preferably diethyl aminoethyl and eluting the active substances at a pH of 2 to 7 by means of a 0.2 to 0.5 molar aqueous salt solution.

Title: Amusement apparatus
IPC: A63F9/00
Filed: 1980-08-11
Granted: 1983-07-06
Abstract: The basic idea is that a device for playing games should be controlled by players without physical contact with the device, to allow a greater flexibility in the control and use of the device. To this end, each player is provided with a terminal unit 22 which is unconnected to the main device 21 except by means of waves transmitted through the atmosphere, e.g. radio, sound or light waves. The player can operate the unit 22 so as to control some function which eventually leads to the result of the game being recorded, for example on a display 23 on the terminal unit. The terminal unit may transmit signals to the device 21 to allow the player to control the start and/or the playing of the game, but a form of apparatus is described in which the player is able to participate actively in a game using a terminal unit which receives signals sent out by the main device and does not need to be equipped with a transmitter.

Title: Data code and apparatus for reading said data code
Inventor: TOMIOKA MAKOTO
IPC: G06K19/06
Filed: 1988-09-05
Granted: 1992-07-22
Abstract: A sheet (1) for data code has decimal numerals or n-ary numerals that represent data codes, such as 1,2,4 or 8 which are displayed in advance in a figure e.g. in four squares having four segments (2(0) to 2(3)). The numerals are arranged in a predetermined order starting from the minimum digits that correspond to binary digit positional numerals, and any one or some of the four segments (2(0) to 2(3)) are blackened. When a black segment is denoted by 1 and a white segment by 0, numerals representing the data codes can be easily converted into binary numerals which can, then, be directly recognised visually. The data code is recognised by projecting the light from a light source onto the sheet 1 for data code, and recieving the reflected light or the transmission light by light-receiving element elements ((5(0) to 5(3)) that correspond to the four segments (2(0) to 2(3)). The light-receiving element corresponding to a black data code produces an output signal 1 and the light-receiving element corresponding to a white data code produces an output signal 0.

Title: Process and apparatus for biological treatment of effluent
Inventor: MCDONALD ALISTAIR JAMES
IPC: C02F3/02
Filed: 1991-04-23
Granted: 1994-12-14
Abstract: Effluent to be treated is introduced into the top of a first bioreactor (10) through an inlet pipe (16) and, after passing through second and third bioreactors (11 and 12), passes through a settling device (17), the treated effluent then flowing over a depth control weir (18) into an outlet pipe (19). The three bioreactors (10, 11 and 12) and the settling device (17) are housed in a tank having three sets of vertically-staggered transverse partitions (21, 22, 23) and a transverse settling tank partition (24). Each set of staggered partitions (21, 22 and 23) are arranged so that the bioreactors are interconnected in series, the effluent preferably being constrained to pass downwardly through each matrix (13, 14, 15) in turn against an upward discharge of very fine air bubbles from aeration panels (28) which extend under substantially the whole of each matrix. Aerobic bacteria feeds on nutrients in the effluent and grows on the roughened walls of the cross-flow matrix and the air bubbles promote sloughing of the bacteria. The apparatus therefore comprises three or more separate total mixed bioreactors working in sequence, each serving to reduce the biological oxygen demand of all the effluent whereby the biological oxygen demand is progressively reduced.
