Patent GB-2521416-A (GB)
Title: Biasing circuitry for MEMS transducers
Inventor: ASTGIMATH SANTOSH
IPC: H04R3/00
Filed: 2013-12-19
Abstract: The switched capacitor voltage converter 102, which may be used to provide a high voltage to bias a MEMS microphone, causes dips in the reference voltage VBG in each cycle because charge is taken from this node to recharge the input capacitors CCP and CCPB. The control circuit 201 of the reference voltage generator acts to restore the reference voltage, but this action is accompanied by a transient in the voltage VPG at the gate of the transistor 202. The current IXA in the transistor 202 may be mirrored in transistor 301 to provide a bias current IXB to a source follower preamplifier (103, figure 3) for the MEMS microphone output signal.Â  To prevent the transient in the nodeÂ VPG causing a transient in the preamplifier bias current IXB, the switch 601 is opened for a short time interval whenever either of the capacitors CCP or CCPB is connected to the reference voltage VBG.Â  The capacitor CC2 reduces the duration of the transient.

Abstract: The present invention discloses a Na-Y molecular sieve and a method for preparing the Na-Y molecular sieve, an H-Y molecular sieve and a method for preparing the H-Y molecular sieve, a hydrocracking catalyst, and a hydrocracking method. The average grain diameter of the Na-Y molecular sieve is 2-5 μm, and the sum of pore volumes of pores in 1-10nm diameter accounts for 70-90% of the total pore volume of the Na-Y molecular sieve. It may be prepared by mixing sodium silicate, high and low alkaline sodium meta-aluminate and aluminium sulphate at a certain mole ratio, aging to obtain a gel, and treating the gel by hydrothermal crystallisation. The H-Y molecular sieve obtained from the large-grain Na-Y molecular sieve can be used as an acidic component in the hydrocracking catalyst. When the hydrocracking catalyst containing the H-Y molecular sieve is applied in the hydrocracking reaction of heavy oils that contain macromolecules, it can provide better cracking activity and product selectivity in the hydrocracking reaction.

Title: Method of forming a cementitious product
Inventor: ANDREW DAVID ARMITAGE
IPC: B28B1/16
Filed: 2016-01-28
Abstract: A method of forming a cementitious product and a method using a wet press process comprises vibrating a grid 20 in contact with a top of a first material between the steps of filling a mould 10 with a first 30 and second cementitious mix. The first and second cementitious mixes are wet having a water-cement having a high workability. The grid is lifted away from the top surface to leave the second material layered on top of the first, before the mould is pressed and cured. Advantageously, using the grid to vibrate the top surface of the first material allows the second material to be layered on top of the first material with limited mixing of the two materials. Consequently, the end product is a layered product, formed using wet press technology and machines, wherein a different material is formed on one surface as opposed to the other.
