Title: Sub-carrier to symbol de-interleaver for DVB-T2 using odd interleaving
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04J11/00
Filed: 2008-10-22
Abstract: DVB-T and DVB-H receivers de-interleave symbols from sub-carriers using a pseudo random sequence generated using an LFSR (linear feedback shift register) 200 whose bits are fed through a permutation matrix 210 to generate the write address for a partitioned deinterleaver memory. The invention provides improved separation between symbols by using an odd interleaving process only (fig 9) for successive sets of data symbols, when the number of data symbols which can be carried per OFDM symbol is less than half the maximum that can be carried. Received data symbols are written using a generated address into the memory and sequentially read out. Applying a cyclic offset to the address that changes from symbol to symbol reduces the likelihood that successive data bits which are close in order are mapped onto the same sub-carrier of an OFDM symbol.

Title: Improvements in the recovery of cream of tartar from wine lees
Inventor: ARDEN THOMAS VICTOR
IPC: C12F3/06
Filed: 1953-04-16
Abstract: 756,854. Recovery of cream of tartar by electrodialysis. PERMUTIT CO., Ltd. April 5, 1954 [April 16, 1953], No. 10458/53. Drawings to Specification. Class 41. Cream of tartar is recovered from wine lees by passing the latter through cation- and anionexchange materials, regenerating the materials with an acid and a base respectively, thus removing the potassium and tartrate ions, and electrolysing the effluent regenerants in separate cells, each divided into two or more compartments by ion-exchange diaphragms. Using two-compartment cells, a solution of tartaric acid is produced from the effluent from the anion-exchange material in the anode compartment of one cell, and a solution of potassium hydroxide from the effluent from the cation exchange material in the cathode compartment of the other cell. By carrying out a reaction between these two solutions a solution of cream of tartar is obtained. The cation- and anionexchange materials can be mixed or separate when the wine lees is passed through them, but must be separated for the regeneration step. The procedure is similar if 3-compartment cells are used, with the addition that pure solutions of caustic soda and sulphuric acid are obtained from the effluents from the anion- and cationexchange materials in the other electrodecompartments of the cells. Specification 751,855 is referred to.

Disc DS2 has projections PJ1, PJ2 located between projections GP1, GP2 on the body to prevent rotation of the disc. Disc DS1 is engaged by projections SP1, SP2 on the stem so as to be rotatable by the stem. The projections SP1, SP2 also act as abutments for contacting body projections GP1, GP2 in the fully open and closed positions of the valve. Rubber or like seal rings SR1, SR2 compressed between disc DS2 and fixture FB, resiliently bias the discs into contact.
