Title: Controlling a bridgeless boost converter
Inventor: MYHRE ERIK
IPC: G05F1/44
Filed: 2007-11-29
Abstract: Method and control system for controlling a bridgeless boost converter comprises a first measuring unit Rs1 measuring a first value representing a first current through a first boost switch Sb1 of the bridgeless boost converter; a second measuring unit Rs2 measuring a second value representing a second current through a second boost switch Sb2 of the bridgeless boost converter and a third current measuring unit Rs3 measuring a third value representing a third current representing the sum of the currents through the components of a stabilization system. A measured signal up is computed by means of the first, second and third currents. A reference signal representing the input voltage Vac is formed. The measured signal up and the reference signal representing the input voltage Vac are input to the control system for controlling the switches so that the measured signal up is substantially in phase with the reference signal representing the input voltage Vac.

Title: Symbol to sub-carrier interleaver for DVB-T2 using odd interleaving
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: G06F7/58
Filed: 2008-10-24
Abstract: DVB-T and DVB-H interleave symbols to 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 read address for a partitioned interleaves 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. Data symbols to be transmitted are sequentially written into the memory and read out using generated address. 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 salve sub-carrier of an OFDM symbol.

Title: Improvements in fluid-operated hoists
IPC: B66F3/24
Filed: 1931-04-02
Abstract: 363,579. Hoists with guided carriers. COOKE, F. A., 4<1>, South Main Street, Cork, Ireland. April 2, 1931, No. 10000. [Class 78 (iii).] A fluid-pressure hoist for receiving casks &c. from a runway and then elevating them, turning them on a horizontal axis and tilting them on to a second runway has a cradle with a depressible slider and means for effecting the control of the plunger and the rotation and tilting of the cask. A cask A from a runway 8 runs over bridge arms 7 on to a cradle 6 carrying a spring-pressed slider 16 carrying valve-operating brackets 21. The cradle is mounted on a guiding cylinder 23 sliding on the plunger cylinder 1 which encloses the plunger 2. Valve-operating brackets 24 are also mounted on the cylinder 23. In operation, when a cask depresses the slider 16 the bracket 21 strikes the arm 45 of a pilot valve 42 which admits pressure fluid from the supply pipe 31 to the main valve 36 and thus raises the main valve and admits pressure fluid from the supply pipe 31 to the plunger cylinder. At the end of the stroke the bracket 24 moves the pilot valve arm and the pressure fluid is released. As the plunger rises a stud 26 held by a strap 27 in engagement with a cam groove 29 in the wall of the cylinder 1 causes the rotation of the cradle and the cask is tipped on to a second runway by the pull of an anchored chain 13 secured to the cradle. Several cam grooves are provided and the studs &c. may be arranged to discharge the cask in various directions.

Title: Improvements in two-stroke internal combustion engines
IPC: F02B25/00
Filed: 1947-04-16
Abstract: 624,799. Pumps; valves. MORIN, R. April 16, 1947, No. 10102. Convention date, May 21, 1946. [Classes 7 (ii) and 7 (vi)] In a supercharged two-stroke internal-combustion engine of the kind in which the cylinder wall is provided with inlet and exhaust ports arranged to be opened and closed by the piston in the course of its stroke, the inlet and exhaust ports are disposed at different levels so that the inlet ports are opened by the ring valve and closed by the piston and the exhaust ports are opened and closed by the piston only, the opening or closing of the inlet ports occurring after the opening or closing respectively of the exhaust ports. Around the mid-portion of the cylinder is located the ring valve 11 which incorporates circumferential ports with tangentially-directed verticallyextending deflectors and baffles. The ring valve 11 is rotated from the engine crankshaft, by means not shown, to co-operate with the piston-controlled upwardly-inclined inlet ports 9 that are supplied depending upon the position of the ring valve 11, from a compressor 5 for scavenging and supercharging purposes. The exhaust ports 8, which are diametrically opposite, but higher than the inlet ports 9, are also above the ring valve 11. The piston 2 is provided with inclined passages 12 in its periphery in order to extend the air admission period during the compression stroke. If the ring valve 11 embodies a greater number of ports than there are inlet ports 9 then it may be rotated at a reduced speed with respect to the crankshaft. In the example shown the ring valve 11 rotates at a quarter the crankshaft speed.

Abstract: 934,228. Counters. AVERY - HARDOLL Ltd. March 2, 1962 [March 20, 1961], No. 10104/61. Class 106 (1). [Also in Groups XXIV and XXVI] The indicating mechanism of a vaned rotor liquid meter is driven through continuously variable speed gearing, the ratio of which is controlled in accordance with the temperature of the liquid. The meter output shaft 14 is connected by gears 19, 22 with the ring gear 24 of a planetary train having a sun gear 27 and planet gears 33 on a planet carrier 31 driving the indicator mechanism through gears 32, 43, 45, 46, 48, 59 and shaft 51. The sun gear 27 is driven by a worm 35 and worm-wheel 28 from an axially movable shaft 34 carrying rigid therewith a friction disc 36 driven from a disc 38 attached to a cup wheel having teeth 42 engaging teeth 25 on the periphery of the ring gear 24. The ratio of the friction gear 36, 38 and thus the ratio of the planetary gear between the meter output and the indicator mechanism, is varied by axial movement of the wheel 36. The shaft 34 is freely rotatable but axially held in a sleeve 55 screwed in a sleeve 56 slidable in the gear support 16 under the action of a forked lever 61. The lever 61 is pivoted on a pin 75 which is displaceable to vary the lever ratio, by a screw and nut mechanism 81, 79 actuated by a manual setting knob 85; a skew shaft 91 actuating a pointer 86 to indicate the position of the pivot pin 75. The end 62 of the lever 61 is actuated by bellows 66 in a cylinder 65 in communication with a closed pipe 68 containing a liquid having a high coefficient of expansion. The liquid being metered is circulated round the pipe and cylinder such that temperature response actuates the lever 61 to adjust the ratio of the gearing, the desired response characteristics being preset by knob 85 and registered by pointer 86.

In carrying out the process, a small amount of the elements referred to above is added, and the malleability at elevated temperature of a specimen obtained from the mass, the procedure being repeated if necessary until a specimen is obtained which is not commercially "red short" and the mass then cast.  The malleability is ascertained by forming a test piece and then subjecting it to the "hammer and anvil test."  The malleabilizing agent used may be either titanium or zirconium together with either phosphorus or boron or arsenic, and these elements may be used in association with one or more deoxidizing or like agents such as magnesium or aluminium.  The molten nickel &c. may be treated with either titanium or zirconium, then magnesium and then either boron or phosphorus, and also with aluminium before the treatment with titanium &c.  Examples of malleabilizing agents used are 0,01 per cent of boron or 0,05 of titanium in conjunction with 0,15 of phosphorus or 0,01 of boron for nickel copper alloys, or 0,01 of zirconium in conjunction with 0,005-0,15 of phosphorus or 0,003-0,02 of boron especially when used in conjunction with 0,05-0,2 of aluminium or 0,02-0,15 of magnesium.
