Title: A method of dynamically adjusting the power of a transmitter in response to the bit error rate of a training sequence.
Inventor: MARTWICK ANDREW
IPC: H04B1/76
Filed: 2009-07-03
Abstract: A method and apparatus for dynamically adjusting power of a transmitter in an interconnect agent is described. A transmitter transmits a pattern to a receiver at a differential voltage (305). If errors are detected at the receiver in the pattern, the transmitter steps the differential voltage until errors are not detected in the pattern at the receiver (315). A method for reducing the number of bits over which the error rate can be determined is also provided. The differential voltage, where no errors are detected, is scaled by a proportion of a target confidence level to a measured confidence level associated with a reasonable length training pattern (320). As a result, a training phase is potentially reduced and power is saved while not sacrificing confidence levels in error rates in the data exchange between the transmitter and receiver.

Abstract: 709,210. Gas turbine plant. GENERAL MOTORS CORPORATION. April 30, 1951 [May 15 1950] No 10022/51. Class 110(3) [Also in Group XXIV] A gas turbine plant comprising a turbine in which the rotor blades are carried by a plurality of discs has the turbine cooled by air from the compressor which passes through an inlet passage in the disc adjacent its periphery then around a portion of the periphery of the disc through an annular passage, in the disc and leaves through a passage in the disc on the side of the disc remote from the inlet passage. Air from the discharge of the compressor 22 which leaks into the chamber 88 passes through a pair of pipes 90 to a space adjacent the face of the first turbine rotor disc 54. From the space which is sealed from the working fluid annulus by a seal 22 and from a fan 60 by a seal 66, the air passes through inlet passages 96 into an annular passage 94 which, it leaves through passages 98. The passages 96, 98 are circumferentially spaced from each other so that the cooling air must travel circumferentially through the passage 94 to cool the blades. The air leaving the passages 98 of the last rotor disc passes through the space between this disc and the partition 118. The pipes 90 also serve to balance the end thrust. Part of the air delivered by the fan 60 passes through apertures 72 and moves radially inwards to a passage 74, leading to an annular passage formed between the inside of the turbine shaft 21 and a thin sleeve 76. This air after cooling the oil in the supply conduit 81 in the bolt 82 and in the return passage formed between the bolt 82 and the sleeve 76. passes through the passage 84 to the space between the last rotor disc and the partition 118 where it mixes with the cooling air from the turbine rotor discs before passing into the turbine exhaust stream. The rear turbine bearing 80 is supported in a sump and oil pump housing 102 enclosed by a cooling chamber 106. Cooling air passes through the struts 114 to the chamber 106 from which it passes through passages 116 in the space between the last rotor disc and partition 118. The main shaft 10 which is supported by bearings 12, 14 and 80 comprises a multiport tubular shaft 10 held together by a tie bolt 82. The shaft 10 is made up of a compressor portion 13, a connecting portion 11 and the turbine portion 21. The part 11 has integral bell mouth flanges 15 at both ends, which engage the parts 13, 21. The flange 15 has splines 17 Fig. 2, which engage splines 19 on the port 21. The forward end of the port 21 has an annular. spherical bearing portion 23 which engages a seat 25. The seat 25 is located in the port 11 by splines and a shoulder member 27. The tie bolt 82 is preloaded by adjustment of the nut 33. The Specification also comprises the subject-matter of Specification 709,256.

Abstract: 1455812 Fruit treatment DEL MONTE CORP 11 March 1975 [18 March 1974] 10112/ 75 Heading A2D  A method of preparing pieces of fruit for long term storage comprises totally immersing the pieces of fruit in an excess by weight of aqueous sugar syrup and continuously conveying the immersed fruit through a heating zone maintained in excess of the sterilizing temperature for the fruit at atmospheric pressure with a sufficient residence time to cause a drop in the liquid content of the fruit pieces and consequent shrinkage of the same and to remove intercellular gases in the fruit to below a level which would cause an off flavour and colour in the fruit during storage under containerization, draining syrup from the fruit, raising the sugar content of the drained syrup to the desired level for shrinkage of the fruit and recycling this syrup, filling the drained fruit pieces at or above sterilizing temperature into containers and sealing the containers with the fruit pieces at or above a sterilizing temperature. The method is applicable to peaches, apples, pears and pineapples. At the beginning of the heating zone, the soluble solids content of the syrup is preferably at least twice that of the fruit pieces. Preferably the fruit pieces shrink by at least 15% after treatment in the heating zone. In the heating zone, the fruit pieces are suitably heated for at least three minutes at a temperature in excess of 190‹F. The soluble solids content of the fruit pieces leaving the heating zone is preferably at least 50% by weight higher than that of the fresh fruit.

Abstract: 851,267. Coating with metals. GENERAL MOTORS CORPORATION. March 25, 1959 [April 28, 1958], No. 10321/59. Class 82(2) [Also in Group XXVI] In an axial-flow compressor, the inner surface of the stator casing opposite each row of rotor blades has a coating which is abradable by the rotor blade tips in motion and is made of porous metal, such as aluminium, bronze or zinc, impregnated with a thermosetting synthetic resin which fills the pores. This ensures minimum clearances between the blade tips and the casing. The surface of the casing opposite the tips of rotor blades 5 is roughened by cutting shallow threads 19 in it or by grit- or shot-blasting it, and is then preferably heated to 175-200F., after which a porous metal coating is sprayed on, the temperature being maintained at 150-200F. as by applying a hot air blast to the opposite side. For a magnesium casing, a coating of 0.003 to 0.005 inch thickness of porous bronze is used. For a steel casing, a coating of stainless steel of about 0.002 to 0.005 inch thickness is followed by a porous aluminium coating of about 0.030 to 0.035 inch thickness. Bronze, zinc or copper may be used instead of stainless steel. At least two coats of a high-temperature resistant thermosetting resin, such as an epoxy or silicone resin, in a solvent or thinner are applied by brushing, spraying, dipping or rolling, to fill the pores of the metal. Drying and curing is effected by baking at about 150 T. for at least half an hour and then baking at about 450F. for one hour. A final bake at about 625F. for about three hours may be given.
