Inventor: GERKE P
IPC: H04Q3/00
Filed: 1960-07-23
Abstract: 954,044. Automatic exchange systems. SIEMENS & HALSKE A.G. July 22, 1960 [July 23, 1959], No. 25675/60. Heading H4K. In a switching stage in which the possibility of setting up a connection between any free inlet and an outlet of a particular group is independent of whether connections to outlets of other groups exist, and in which such a connection is set up under control of a marker, use is made of testing networks each arranged to cover only the possibilities of connection between the inlets and a single group of outlets, there being as many such networks as there are different types of outlet group, the networks being connected in common to a first group of wires connectable to the inlets to be served, and the outlets of a wanted group being connectable through a second group of wires to that network which is suitable for the outlet group in question. The switches employed are cross-point matrices, the cross-point contacts not being shown. The inlets 1-k are multipled to the column wires, but the outlet (horizontal) multiple is split. The testing networks Sr, Sq consist of two-input AND gates of which the resistors are common to the gates of Sr and Sq, the first input of each gate being connectable via one of the wires PI to an inlet and the second via one of the wires PII to an inlet to which that outlet may have access. The outlet groups have either r or q (q<r) outlets and the corresponding network Sr or Sq is connected up in each case, The out. put conductors of the network gates are connected to the input terminals of a one-at-a-time selector W which chooses one of the inlets which corresponds to a free path through the stage viz., inlet free and outlet free. This determines the inlet and outlet to be connected together, and the marker sets up the required connection. Thus to set up a connection to an outlet of the second row of switch B31 the contacts 311-31k are closed to connect the wires PI to the inlets of B31, contacts 3121-312q to connect PII to the second row outlets, and contacts 123- (k-2)(k-1)k to connect up Sq. Free inlets have negative free potential thereon, and busy outlets positive busy potential. As resistances Z1-Zk have higher values than the forward resistances of G1q-Gkq the busy potential overrides the free potential, so that negative free potential appears only at those inlets of W which correspond to free inlets and free outlets. One such inlet is chosen by the selector W and the connection is set up by the marker (not shown). Specifications 904,463 and 945,357 are referred to.

Abstract: 1,043,469. Automatic attitude control. ALBISWERK ZURICH A.G. June 29, 1964 [June 28, 1963], No. 26767/64. Heading G3R. In an error-actuated servo-system at least two error signals having uncorrelated random fluctuations are produced by partly independent measuring units and the smallest error signal is automatically selected for control when the error signals are of the same polarity. In Fig. 2 (not shown), a radar aerial 1, coupled to transmitters 6, 7 operating at different frequencies, makes a conical scan, and associated receivers 8, 9 each produce a pair of D.C. signals corresponding in magnitude and polarity to the magnitude and sense of horizontal and vertical displacement between the axis of the aerial and the direction of a target aircraft. The two horizontal displacement signals are applied to a diode rectifier network 10 which, if the two signals are of opposite polarities, produces no output, but which, if the signals are of the same polarity, applies the smaller of the two to control a follow-up motor 2 eliminating the displacement. A similar diode circuit II eliminates vertical displacement by selecting the smaller of the two vertical displacement signals, if they are of the same polarity, to control a follow-up motor 3. The diode networks, which are described in detail, include a valve amplifier to compensate for attenuation by network resistance.

Title: Slurry expolsive compostion
Inventor: ENEVER J
IPC: C06B47/14
Filed: 1980-10-28
Abstract: An aqueous slurry explosive blasting composition comprising an aqueous suspension of water-soluble crystalline oxidising salt consisting predominantly of ammonium nitrate, which salt has been comminuted in a saturated aqueous solution in the presence of a water-soluble crystal-growth inhibiting surfactant having a hydrophobic portion and a hydrophilic portion in its molecule, in intimate admixture with liquid water-immiscible hydrocarbon fuel sensitiser. The surfactant maintains the oxidiser salt in a finely divided state and also ensures that the liquid hydrocarbon remains uniformly distributed throughout the explosive mass as a stable coating of droplets on the salt particles thereby enhancing the explosive sensitivity of the composition. The preferred fuel is diesel oil and preferred surfactants include sodium carboxymethyl cellulose, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes, sulphonated polymers and long chain alcohol sulphonates and phosphonates.

Abstract: PCT No. PCT/GB87/00889 Sec. 371 Date Sep. 26, 1988 Sec. 102(e) Date Sep. 26, 1988 PCT Filed Dec. 8, 1987 PCT Pub. No. WO88/04414 PCT Pub. Date Jun. 16, 1988.A radiation meter for measuring the intensity of incident ultraviolet radiation in a predetermined wavelength band against a background of broadband radiation, such as sunlight, includes a sheet of a material incorporating a fluorescent dye. The dye is selected to absorb radiation in the predetermined wavelength band and consequently to emit fluorescent radiation. The fluorescent radiation is internally reflected within the sheet and emerges from an edge of the sheet, where it impinges on a photodiode. The photodiode produces an output which is dependent upon the intensity of the ultraviolet radiation. This output is used to drive a suitable display. The unwanted background radiation passes through the sheet without causing fluorescence of the dye, and is absorbed in an absorbent backing layer. The photodiode is so positioned and screened that the background radiation cannot impinge upon it. A particularly advantageous use of the meter is for measurement of the intensity of ultraviolet band radiation, which is the cause of sunburn and skin cancer.

Title: Operation of power station
Inventor: REICH WERNER DR ING
IPC: F01K23/06
Filed: 1993-06-30
Abstract: The invention concerns a method and device for the operation of a combined-process power station burning solid fuels, in particular lignite, the compressed hot air heated in a heat exchanger (7, 8) through which the exhaust gases from a boiler (1) pass being further heated by a separate combustion process (18) to give a hot-air/exhaust-gas mixture which is then fed to a gas turbine (28). The aim of the invention is to ensure that the power station can be operated efficiently and safely when burning solid fuels, in particular lignite. This is achieved by virtue of the fact that the hot air is further heated indirectly in a separate, series-connected, solid-fuel-fired combustion chamber (18) with facilities for liquid-ash removal and the exhaust gases from this series-connected combustion chamber are utilized, independently of or in conjunction with the exhaust air from the gas turbine, in the power-generation process or in separate processes to produce energy.

Title: Unactivated oocytes as cytoplast recipients for nuclear transfer.
Inventor: CAMPBELL KEITH HENRY STOCKMAN
IPC: C12N15/877
Filed: 1996-08-30
Abstract: A method of reconstituting an animal embryo involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be donated by a cell in either the GO or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor such as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.
