Patent GB-2610282-A (GB)
Title: Improved sound amplification apparatus
Inventor: TERRY BATEMAN
IPC: H03F3/217
Filed: 2022-07-04
Abstract: An audio amplifier 3 wherein as the power output increases above 20 Watts the heat output of the amplifier increases by no more than 25% thereby allowing the amplifier to operate at Class A audio quality over a larger power output range of 10-100 Watts. The amplifier accomplishes this by having two Darlington pairs TR3, TR8 arranged in series across a power supply +PWR, -PWR. The amplifier output 4 is taken from the between the emitters of Darlington pairs. A circuit V2, TR12 biases the Darlington pairs. A compound pair emitter follower circuit TR1, TR5 provides the drive signal to the Darlington pairs. The quiescent current of the power amplification circuit may be 70-90 mA. An input error amplifier and voltage amplifier (block A, Fig, 3) may precondition the signal before amplification. The input error amplifier may comprise long-tail pair TR6, TR7 connected to a current mirror TR9, TR10 to improve open loop gain frequency response. More than one of the amplifier circuit (D, E, Fig.6) may be implemented in parallel, both amplifiers receiving an input from the input error amplifier (C, Fig.6).

Title: Photocatalytic material for degrading tetracycline in wastewater and preparation method thereof
Inventor: ZHI SONG
IPC: B01J35/00
Filed: 2022-11-10
Abstract: A method for preparation of a photocatalytic material for the degradation of tetracycline in wastewater. Zinc oxide nanorods are placed into an aqueous suspension comprising tungsten trioxide, polyvinyl pyrrolidone. A silver salt is then added to the suspension followed by a phosphate salt. A second aqueous mixture comprising aluminium hydroxide, sodium hydroxide, tetrapropylammonium hydroxide and colloidal silica is aged between 75 and 95 ℃ for between 8 and 24 h to obtain a molecular sieve synthesis agent. The molecular synthesis agent is added to the zinc oxide nanorod suspension and mixed using an ultrasonic treatment, the mixture is then subjected to a microwave hydrothermal reaction at 120 to 180 ℃ for 10 to 120 mins to obtain the photocatalytic material.

Abstract: This invention relates to a new ceramic-metal composite body and a method for producing the same. Particularly, a compliant layer composition is utilized for preventing the rupture of a ceramic article (1) and/or the yielding or failure of a metal during the pouring, solidification and cooling of a molten metal which has been cast around the ceramic. A slurry composition for the compliant layer (2) includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the ceramic article (1) and thereafter is heat-treated to form a compliant layer (2). Ceramic-metal composite bodies comprising low strength hollow articles and high expansion coefficient metals may be manufactured according to the method of this invention.

IPC: H01L21/48
Filed: 1990-03-15
Abstract: The method of producing a means of electrical connection, particularly interconnecting substrates for hybrid circuits, involves the deposition of a layer of untreated ink on a highly heat- dissipating support such as aluminium nitride, followed by a preliminary drying of the ink at a temperature of the order of 100 DEG C to 150 DEG C. This is then followed by firing consisting of
 (a) an elevation in temperature incorporating a phase for the removal of the polymer resins,
 (b) a sintering stage at a temperature of the order of 600 DEG C to 1000 DEG C and
 (c) a delayed cooling. The characteristic feature is that the atmosphere during the stage at which the polymer resins are removed has a low oxygen content lying between 100 ppm and 5000 ppm, whereas the oxygen content of the atmosphere during the high temperature sintering and of the cooling atmosphere must be below about 10 ppm.

Abstract: Disclosed is an improved parallel system bus structure comprising a plurality of bus wire-printed disks (5) each having a plurality of signal conductors (6) of equal length extending radially from a common central contact (7). These bus disks (5) are spaced vertically at regular intervals, and a plurality of connectors (12) are fixed to the circumference of the bus disks to permit connection between the signal conductors of the bus disks and the terminals of the CPU board. The radial arrangement of signal conductors (6) permits connection of selected CPU boards via equal length signal paths, no matter how many CPU boards may be used.

IPC: F16B33/06

Abstract: An austenitic stainless steel screw has a surface formed into a hard nitrided layer, and a part such as a screw head which is in contact with outside air has its ultra hard surface layer of the hard nitrided layer removed by scouring or the like, to be rust resistant. Even when the ultra hard surface layer is thus removed, an inner hard layer of the hard nitrided layer which was present beneath the surface layer remains to maintain the hardness of the screw surface. A method for manufacturing the austenitic stainless steel screw includes, upon forming the hard nitrided layer on the screw surface by nitriding, cleaning the austenitic stainless steel screw surface with a fluorine- or fluoride-containing gas prior to nitriding. Thereby, any remaining foreign matter or oxidized layer or the like on the screw surface is removed and at the same time the screw surface is activated so N atoms easily penetrate and diffuse during nitriding to form a uniform nitrided layer.
