Title: Multicarrier transmitter for multiple-input multiple-output communication systems and methods for puncturing bits for pilot tones
Inventor: DAVYDOV ALEXEI
IPC: H04L1/00
Filed: 2006-09-21
Abstract: Embodiments of a transmitter and methods for puncturing bits are generally described herein. Other embodiments may be described and claimed. In some embodiments, a multicarrier transmitter performs bit puncturing for pilot subcarriers in two operations. The first operation may uniformly removes bits from an encoded bit stream to achieve a predetermined code rate reserving space for pilot subcarriers of a predetermined number of antennas. The second operation may remove bits from each spatial data stream after interleaving in a manner to achieve approximately equal spacing between the punctured bits before interleaving. In this way, a conventional interleaver may be used. The second operation reserves space for pilot subcarriers when a greater number of antennas than the predetermined number are used.

Title: Intraocular lens with variable optical power depending on orientation
Inventor: GHABRA MARWAN
IPC: A61F2/16
Filed: 2009-12-22
Abstract: A vision correction arrangement is described in which a lens system has a variable optical power depending on the orientation of the user's eye. The arrangement may be an intraocular lens implant, or an extraocular device such as spectacles. The arrangement 10 comprises a fixed lens element 11 and a movable lens element 12 sensitive to the orientation of the eye, so that the optical power of the arrangement is increased when the user looks downward, and is reduced when the user's eye returns to the horizontal. The fixed lens 11 element may have a convex rear surface 14 and a concave front surface 15, and the second lens element 12 may be pivotally mounted 16, 17, 18 in front of the first lens element 11 like a pendulum. Downward inclination of the eye causes the second lens element to pivot and swing away from the fixed lens element (see figure 5). Alternatively, the movable lens 11 may slide within a channel 31 away from the fixed lens (see figures 6-7), or it may be buoyant and bend a flexible link (33, see figures 8-9).

Title: Humidifying method and apparatus
IPC: D01G99/00
Filed: 1953-04-13
Abstract: <PICT:0725463/IV (c)/1> In a humidifier, a continuously travelling material passes through a relatively quiescent area, then through a uniformly moving stream of humid atmosphere flowing in the opposite direction to the material and finally into an area where jets of steam are directed at an angle against the direction of the travelling material.  A web, Fig. 1, passed over guide roll 3, enters the humidifier through a slit 16 and leaves through slit 16a, passing over roll 4.  Steam, entering through pipe 38, passes into headers 35, 35a feeding nozzles 36, 36a in transverse pipes 34, 34a, the steam being withdrawn from the chamber through ducts 17, 18 by a p motor-driven suction fan 29.  The chamber is provided with insulating walls 13, 15 and is heated by steam passing through coils 49, 49a, further coils 53 being arranged around the inlet and outlet slots 16, 16a.  The coils 49a are disposed in the drip pan 47.  In operation, slide-plates 23 are adjusted by knobs 25, and dampers in the duct leading to duct 28 are rotated so that there is a slight excess of steam in the chamber which passes out of the slots 16, 16a over felts 52.  The web passing through slot 16 enters the humid atmosphere where it is quiescent and after passing the suction ducts, moves into an area where the atmosphere is moving in counter-direction to the material, subsequently the steam from nozzles 36, 36a impinges on the web.  The pipes 34, 34a are curved upwards and the nozzles 36, 36a arranged, Figs. 4 and 5 (not shown) so that any condensed liquid passes out through steam traps 41, 41a.  In a modification, Fig. 6 (not shown), the line 16, 16a is arranged to be vertical.

Title: Improvements in or relating to the control of feed water to forced feed tubulous steam generators
IPC: F22B35/06
Filed: 1934-04-03
Abstract: 436,087. Instantaneous steam boilers. DEHN, F. B., 103, Kingsway, London.- (Doble Steam Motors, Ltd.; 4053, Harlan Street, Emeryville, California, U.S.A.) April 3, 1934, No. 10071. [Class 123 (ii)] In a forced feed boiler comprising a long tube coil through which water is forced, steam issuing from the outlet end, the feedwater control comprises two thermostats one increasing or throttling the inlet in response to the temperature of the inlet end section without completely closing it, and the other being capable of effecting a complete stoppage of feedwater supplied to an intermediate point. Feedwater is supplied from a tank 16 to a primary inlet 12 and a secondary inlet 41 of the boiler tubing 6. The boiler is fired by means of a blower 9 which forces air over a carburetter 10. At low temperatures a rocker arm 24 separates contacts 36, 37 in an electrical circuit which includes the solenoid 38 of a valve 39 in the secondary feed supply : on a predetermined temperature rise a thermostat 21 forces the rocker arm to permit the contacts to abut with the result that water is supplied at inlet 41 and the temperature normally falls. Should conditions be such that the temperature rises materially above the predetermined value the thermostat is caused to separate contacts 33, 34 in the blower circuit. A second thermostat 46 is disposed on the main inlet side of the secondary feed supply and controls through a bell-crank 48 and rod 49 the main feed valve 51 so as to throttle this supply to a rate corresponding to the temperature in the primary portion of the boiler. A constant pressure drop is maintained across the valve as by means of a spring-loaded piston 56 associated with a lever controlling a valve 63 in the pipe conveying operating fluid to the feed pump 17. In a modification a varying portion of the feedwater is passed through a valved conduit byepassing valve 51 in accordance with a steam outlet throttle 4, and the thermostat 46 is caused to separate contacts in the blower circuit if the temperature at this point becomes excessive.

Title: Recovery of hafnium and/or zirconium values
IPC: C01G27/00
Filed: 1963-03-14
Abstract: Titanium values are removed from zirconium and/or hafnium values by distribution between an aqueous acid and a water immisible organic liquid in the presence of a peroxide or peroxy-compound. Acids may be nitric, sulphuric, hydrochloric or acetic and peroxides or peroxy-compounds may be hydrogen, sodium, barium or potassium peroxide, peracetic acid or isopropylperdicarbonate.  The organic solvent, of which numerous examples are listed, may be diluted with liquid hydrocarbons, e.g. normal hexane or normal octane.  The metal values, in e.g. tributyl phosphate solution, are introduced into a central area of an extraction tower, the organic solvent into a lower stage and the aqueous acid with the peroxide into an upper stage. The downward flowing aqueous acid extracts the titanium values, while the organic phase contains the zirconium values. The hafnium may appear in either phase depending on the conditions and a second extraction under modified conditions completes the separation.  A multistage extraction is also described.  The metal values are usually present in the initial composition as the nitrate, sulphate, chloride or perchlorate.  Reference has been directed by the Comptroller to Specification 800,426.
