Title: Separation of molecules and materials therefor
IPC: C07H1/06
Filed: 1971-12-15
Abstract: 1421531 Selective sorption UNITED KING- DOM ATOMIC ENERGY AUTHORITY 29 Nov 1972 [15 Dec 1971] 58374/71 Heading B1H [Also in Division C1] In making discrete particles for the selective retention of macromolecules, finely-divided solid particles of a sorptive inorganic material are mixed with a fugitive additive and a solvent therefor, the inorganic material being insoluble in the solvent, the mixture is formed into discrete green particles containing the fugitive additive in solid form, and the green particles are then heated to remove the fugitive additive and cause sintering of the inorganic material to provide discrete particles having an interconnected pore structure capable of penetration by macromolecules. A sorptive inorganic material is defined as one that is capable of retaining macromolecules by adsorption or absorption or which can be treated to make it so capable, e.g. titanium dioxide, alumina, calcium phosphate, larium sulphate, calcium sulphate, a zirconium oxide, or natural earths such as celite. Specified fugitive additives are ammonium carbonate, haemoglobin, polyvinyl alcohol, dextran, urea, lorine serum albumin and ovalbumin. The green particles, e.g. spheroids, are suitably formed by spray-drying or by vibration (see Specification 1033143). The final sintered aggragate particles may be 50-600Á in size, having interconnected pores of 1000-10000Š. The products are used for selective sorption of macromolecules from fluids, and may be tailored to sorb particular macromolecules by selecting appropriate preparative conditions and fugitive additive. In one example, TiO 2  (<10Á) is slurried in a mixture of aqueous ammonium carbonate solution and glycerol, as a binder. The product is dried and the resulting particles are sieved and then spheroidized to form green spheres (50-500Á), which yield porous spheres on heating to 900‹C for 2 hours. In further examples, porous particles of Ca 3 (PO 4 ) 2 , BaSO 4 , Al 2 O 3  and celite are produced, and the use of TiO 2  particles in protein separation is exemplified. Suitable combinations of inorganic sorptive material, fugitive additive and preparative coaditions for partioular purposes are suggested.

Title: Loop detection in a telecommunication system
IPC: H04M19/08
Filed: 1969-12-04
Abstract: 1,241,079. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Dec., 1969 [7 Dec., 1968], No. 59275/69. Heading H4K. In a system having substations which include transistorized amplifiers that are fed over the line, each station is normally shortcircuited by a low impedance device (when the handset is lifted) so as to increase the current flow available for loop detection, the device being cut-out of circuit so that current is supplied to the amplifier in the station once the exchange has detected a loop. The device is a diode which is cut-out simply by reversing line polarity when the loop supervision relay comes-up. It is pointed out that the use of transistor amplifiers in substations increases the resistance presented to line so that if the line is long the possibility of a high resistance loop detector not responding correctly is increased. As shown, the diode may be located across the hook switch as at G1 or across the outgoing speech amplifier as at G2. In either case lifting of the handset causes relay S to come up and thereby reverse line polarity so that the diode is back-biased and operating current may be drawn by the substation. The windings of the relay may be connected directly to the battery terminals so that the current therethrough is not reversed when the line polarity is reversed by the operation of the change-over contacts.

Title: Electrophotographic development apparatus
IPC: G03G13/06
Filed: 1978-07-12
Abstract: An electrophotographic copier is described in which dry toner (T) is fed to the outer surface (5) of a photoconductive drum to develop an electrostatic image. The dry toner (T) is stored in a hopper (9) and the toner (T) is extracted from the bottom of the hopper by a roller (7) or belt which brings the toner (T) past doctor (9a) into contact with the image and develops it. An electrode (10) is immersed in the toner in the hopper and is energised to impart an electrostatic charge of one polarity or the other to the toner. This enables positive and negative image development to be achieved far more readily than in previously proposed copiers in which the toner was triboelectrically charged. In an alternative arrangement [fig. 7 (not shown)] the roller is disposed above the hopper and the electrode, in the form of a roller, contacts the developer on the surface thereof. <IMAGE>

Title: Signalling systems
IPC: H04M7/06
Filed: 1978-12-12
Abstract: In a modern telecommunication system of the "integrated network" type it is necessary for the individual telephone exchanges to be able to communicate signalling information to main centres such as group switching centres, and to such centres as centralised accounting centres. To enable this to be done an exchange has one or more signalling terminals, each of which provides several commonly-available signal channels for such communication. The signalling terminal or terminals is or are under the control of a processor (duplicated in the interest of security) with which there is associated a memory for the addresses of the centres to which messages are to be sent. This processor controls message assembly and transmission. In certain cases the processor may perform certain additional functions, such as those of the so-called management processor, described in our Patent No. 1 467 641.
