Patent ZA-833736-B (ZA)
Title: Method of regulating the heat transfer coefficient of a heat exchanger and improved heat exchanger to employ said method
Inventor: CHRYSOSTOME GERARD
IPC: F28F27/00
Filed: 1983-05-24
Abstract: Method and apparatus for regulating the heat transfer coefficient between a granular material and an exchange surface inside a heat exchanger in which a descending flow of a charge of material is arranged in the form of a mobile bed in contact with an elongated exchange member extending between lower and upper levels of the tank of the exchanger. The latter is provided with injection means for a gas into the charge of material. The flow conditions of the gas passing through the charge from below upwards are regulated so that the ascending flow speed is initially less than, at the base of the tank, the critical fluidization speed and then increases gradually to reach such critical speed at an adjustable level comprised between the lower and upper levels of the exchange member. The invention is especially applicable to heat exchangers used for cooling a granular material and/or for the heating of a heat transfer fluid.

IPC: A01N59/12
Filed: 1984-02-24
Abstract: The microbicidal effectiveness of pharmaceutical iodophor preparations comprising an organic substance which reacts with iodine to form a complex thereof, such as polyvinylpyrrolidone, iodine bound thereto in complex form, free iodine, and iodide ions, is assured by controlling the ratio of total iodine (complex bound iodine and free iodine) to iodide ions at between 2:1 and 10:1, this ratio being adjusted without chemical oxidizing agents such as iodate ions by anodic oxidation of a solution of the iodophor preparation and iodide ions. The resulting preparation can be free of chemical oxidizing ions such as iodate ions.

Title: Circuitry for detecting a television signal
Inventor: LENZ KUNO
IPC: H04N5/44
Filed: 1990-12-11
Abstract: A circuit for detecting a square wave television signal in a television receiver includes an oscillator for generating the square wave signal and a phase locked loop (PLL) for synchronizing the square wave signal with the syn pulses of the televsion receiver. The circuit also includes an integrator for switching the output signal of the PLL to a frequency stable square wave signal when the syn pulses are absent and a Schmitt trigger for closing the PPL when a threshold value is reached. With the invention, the syn signals are sensed and a first switchable constant current source increases the output voltage of the integrator for a predetermined period of time when syn pulses are present during the first half of the square wave signal and discharges the integrator when syn signals are absent from the second half of the square wave signal.

Title: Chimeric fibroblast growth factor
Inventor: SEDDON ANDREW P
IPC: A61P17/00
Filed: 1991-11-22
Abstract: The present invention relates to novel chimeric fibroblast growth factors (FGF) wherein the alanine at amino acid 3 and serine 5 of native human recombinant basic fibroblast growth factor are replaced with glutamic acid. The N-terminus sequence of the present chimeric FGFs identify homology with that of human acidic fibroblast growth factor. The mitogenic properties of the native human recombinant basic FGF are exhibited by the present chimeric FGFs, and they are efficiently expressed in E. coli at significantly greater yields that previously reported. Novel variants of this new glu<3,5> basic fibroblast growth factor, such as those in which cysteine 78 and cysteine 96 are replaced, e.g., with serine or other amino acids, to produce stabilized versions of the glu<3,5> basic FGF and eliminate disulfide scrambled forms, are also described. <IMAGE>

Patent GB-2116767-B (GB)
Title: Testing coins
Inventor: DEAN ROBERT
IPC: G07C3/00
Filed: 1983-02-11
Granted: 1985-10-16
Abstract: The operation of a coin testing apparatus is checked by switching the apparatus to a test mode. In the test mode, the properties of items inserted into the apparatus are compared with stored «test» ranges, instead of «acceptability» ranges which are normally used to determine whether the item is a genuine coin. A specially designed non-genuine coin is then inserted into the apparatus. If the measured properties of the non-genuine coin fall within the «test» ranges, a signal is produced to indicate that the apparatus is operating correctly. If any of the properties falls outside a «test» range, but within a further, contiguous range, a signal indicates that the apparatus is working adequately, but not optimally.

Granted: 1985-11-13
Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.

Title: Laminated tape
Inventor: MCGEARY MICHAEL LAWRENCE
IPC: H01L23/495
Filed: 1993-12-17
Granted: 1997-07-30
Abstract: A flexible laminated interconnect tape is suitable for use as an electrical interconnecting medium between electronic components and between bonding pads of integrated circuit die and IC packaging bond pads. The tape may be used as a modification to existing TAB (tape automated bonding) tape technology, or as a substitute to wire bond technology. The flexible laminated tape comprises a plurality of conductor layers (40)(a - y) eg of Al, each separated from adjacent conductor layers by a polymeric insulating layer (42)(a - z). The tape offers improvement to bonding processes by simplification of the requirement to create compatible metallurgies at the bond sites. By using vacuum deposition techniques to form the electrical conductor a wider range of materials (and characteristics) is made available for electrical interconnect. Benefits may also follow in the high-frequency signal transmission between interconnected components by reducing "skin effect" attenuation; this laminated tape could be regarded as an evolution of Litzendraht Wire. <IMAGE>
