Title: Preventing boot crashes due to new files
Inventor: HARTMAN PETER
IPC: G06F11/14
Filed: 2009-06-30
Abstract: New files to be loaded in a computing device during a boot-up process of said computing device are identified and a determination made whether loading at least one of the identified new file(s) causes the computing device to crash. A list on the computing device in dependence on whether the loading of the identified new file(s) causes the computing device to crash is updated and during a booting process, files are loaded depending on the list, to prevent the computing device crashing during any re-boot. Determination may be made by booting the device, such as a mobile phone, and checking that it has not crashed, or verification check may be made on files before they are installed, such as ensuring that they are not zero sized files. The list may have a valid and an invalid portion to maintain tags representing the files.

Title: Nanoparticles and fabrication thereof
Inventor: MENDOZA CESAR E
IPC: C08J3/20
Filed: 2008-05-06
Abstract: Creation of nanoparticle structures in two and three dimensions is advantageous in providing a number of functions such as in relation to catalytic, optical, electronic and magnetic propertied and other actions. Fabrication of such structures poses a considerable technical challenge. A block copolymer pair is used as a matrix to spatially organizes and aligns loaded inorganic materials in the form of nanoparticles. The inorganic precursors are selectively incorporated to a specific block of a di or tri block copolymer so that through solvent evaporation, reduction and mechanical working such as LAOS the orientation and positioning of the block copolymers nanoparticles are obtained into a desired structure.

Title: Femtocell, base station, Femto Gateway, and communication method thereof
Inventor: HSU HENG-LANG
IPC: H04L29/06
Filed: 2009-12-03
Abstract: A network system (2) comprises a base station (25) connected to a femto gateway (29) by way of the Internet (27). Femtocells (211, 231) are each individually connected to the femto gateway (29) by way of the base station (25). Each femtocell (211, 231) turns off its RF transceiver when the RF transceiver has been idle for a predetermined time interval. When the base station (25) determines that a mobile station (233) has entered its signal coverage, the base station transmits a notification signal (202) to the femto gateway (29). In response to the notification signal (202), the femto gateway (29) transmits a turn-on signal (204) to the femtocell (231) via the base station. Since the femtocell (231) only turns on its RF transceiver (231c) when a mobile station needs its service, the femtocell consumes less power. In addition, interferences between femtocells can be reduced.

Patent GB-161190-A (GB)
Title: Improvements in or relating to electric relay systems and apparatus
IPC: G05D3/12
Filed: 1919-11-28
Abstract: 161,190. Sperry, E. A. Nov. 13, 1914. [Convention date]. Steering, controlling from a distance.-Relates to electric relay apparatus for transmitting rotary movement to a distance and allowing heavy current to be used at the receiving station. The apparatus described is particularly applicable to copying the movements of a gyro-compass on repeater instruments or for controlling a steering- motor from the compass as described in Specification 135,871. A transmitter 92 serves to close in cyclic succession circuits of pairs of field windings of a step-by-step motor 112. The armature shaft carries a contact drum 32<1> having two contact segments co-operating with a roller contact 33<1>. Movement of the drum from the position in which contact 33<1> rests on an insulating strip energizes one other of two opposed fieldwindings 212, 213 of a second motor 211 which drives contact 33' to seek the insulating strip and break the field circuit when the two motors are in phase. Motor 211 also drives a transmitter 121 which controls a step-by-step motor 16, which in turn controls a steering motor 6 by contacts 32, 33 in a manner similar to that above described. Contact 33' is carried on a bar 127 with a forked end 127<1> and supported by springs 126 on a frame 125, 120 secured to a shaft 117 driven by motor 211. Shaft 113 of motor 112 is in line with shaft 117 and carries contact drum 32<1> and an elongated pinion 115. Frame 120, 125 carries a shaft 121 having a pinion 128<1> engaging pinion 115, and a mutilated pinion 129. Shaft 121 is threaded as shown so as to receive a longitudinal movement when rotated in its bearings 123, 124. Shaft 117 carries the contact drum of transmitter 121. This drum has four sections co-operating with brushes 119. Three sections have pairs of oppositely disposed contact segments of 90‹, the contacts of each section being stepped 60‹ with respect to those in the adjacent section. Shafts 113, 117 are prevented from getting one or more complete revolutions out of step by rotation of shaft 121 which occurs when shafts 113, 117 run at different speeds. This rotation causes pinion 129 to rock pivoted member 130 connected by a link 132 with a bell-crank lever 133 engaging fork 127<1> and moving contact 33<1> axially along the drum 32<1>. Pinion 129 is then moved longitudinally out of engagement with member 130 and remains there until shafts 113, 117 regain their original relative angular position. The motor 16 may be geared directly to an indicating mechanism such as a repeater compass.

Title: Improvements in or relating to generation of hydrogen containing synthesis gas
IPC: C01B3/36
Filed: 1948-04-10
Abstract: In a process for generating hydrogen-containing synthesis gas by the vapour phase reaction of liquid or gaseous hydrocarbons, e.g. methane, and oxygen of not less than 95 per cent purity under a pressure of 100-500 lbs. per sq. inch, the formation of carbon is substantially <PICT:0646532/III/1> eliminated by passing the reactants through the reaction zone, at above, say, 2000 DEG  F., at a rate such that the contact time of the reactants is at least double the contact time required when the reaction zone is at atmospheric pressure, e.g. 1-20 secs.  The hydrocarbon and oxygen are reacted, preferably in a reactor free of catalyst or refractory packing, in such proportions that the synthesis gas contains not more than 5 per cent carbon dioxide and 5 per cent hydrocarbon and are preheated to 600-1000 DEG  F.  Oxygen, passing from 47 through valve 38A, pipe 37, and heat regenerator 36 to steel generator 30 lined with refractory 34, contacts methane, passing from 42 through heat-exchanger 43, valve 40A, and pipe 41, in reaction zone 35.  The product gas passes out through heat regenerator checkerwork 361 to be exhausted, through pipe 371, valve 39A and heat exchanger 43, at 46.  When the checkerwork 361 no longer cools the product gas effectively, the cycle is reversed; a simpler reactor with heat regenerators is also described.

Abstract: 880,817. Electroluminescent devices. THORN ELECTRICAL INDUSTRIES Ltd. March 4, 1960 [March 24, 1959], No. 10210/59. Class 39(1) A device for converting sonic into luminous effect comprises a sound-responsive member, e.g., an aluminium foil 14 or a plastic film provided with a conducting surface, having a number of surface elements adapted to be exposed to a sound pattern, each element, when the device is suitably connected to a voltage source 15, generating a voltage representative of the sound falling thereon by changes in the capacitance or resistance between the member 14 and a conducting transparent film 11, and an electroluminescent member 12 arranged to surface of the member 12 a light pattern corresponding to the sound pattern. The surface element of the foil 14 may be defined, as shown, by a silk meshed supporting layer 13 or by a layer of small glass beads with the interstices filled with liquid, or may be defined by a continuous yielding layer, e.g. of soft plastic or of oil, interposed between the foil and the electroluminescent layer 12. The layer 12 may be formed of a mixture of electroluminescent and dielectric materials and a further layer of dielectric material as in Specification 798,503 may be interposed between the foil 14 and the layer 12. The device may be operated by D.C. or A.C. and the voltage variation may be generated by changes in electrical resistance by using conductive material such as graphite between the foil 14 and the layer 12 and incorporating graphite or stannic oxide in the layer 12. The sound-responsive layer and the electroluminescent layer may be physically separated with an electrical connection between corresponding surface elements.

Title: Improvements in and relating to centrifugal pumps
Inventor: FRANKS HAROLD JOSEPH
IPC: F04D1/06
Filed: 1954-04-07
Abstract: 774,296. Centrifugal pumps. SAUNDERS VALVE CO., Ltd. April 7, 1955 [April 7, 1549], No. 10271/54. Class 110 (1). In a multi-stage centrifugal pump, the suction passage leading to the eye of the first stage impeller and the discharge passage for the whole pump are formed in a common end head at the end of the pump casing nearer the first stage impeller, and the pump is primed by re-circulation from the discharge passage through a nozzle incorporated in the common end head and directed towards the eye of the first stage impeller, an automatic valve being provided to stop re-circulation when the pump is primed. The multi-stage pump shown comprises four stages, the second stage impeller facing in the same direction as the first stage impeller 11 and the third and fourth stage impellers facing in the opposite direction to reduce end thrust. The discharge from the fourth stage passes by way of a passage 22 to a discharge chamber 27 which surrounds the suction chamber 26. Priming is effected by recirculating liquid from the discharge chamber 27 to the eye of impeller 11 by way of passages 30 and 32 and a nozzle 28. On completion of priming, a valve ball 33 is swept upwards by the liquid against a seat 31 to stop the recirculation. A by-pass passage 35 prevents the ball 33 from being swept upward too soon, the tendency being for the liquid to pass through the passage containing the ball 33 and for the air that is initially present to be directed through the passage 35. The suction connection 36 and discharge connection 37 are arranged above the centre line of the pump to ensure that once the pump has been primed for the first time a sufficient quantity of liquid is left in the chamber 27 to facilitate subsequent priming by the described re-circulation.

Filed: 1935-04-04
Abstract: 459,587. Drying vegetable material. SARNMARK, A U., 1, Skeppsbroplatsen, Gothenburg, Sweden. April 4, 1935, No. 10508. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 5, 1935]. [Class 34 (ii)] [See also Groups I, V, VI, and XII] Raw vegetable material such as oats, rye, barley, corn, potatoes, with or without flavouring, and like matters is mixed in a container 10 with water or milk and yeast &c., and passes by a pipe 12 to one or other of two receptacles 16, 17. These receptacles are connected by a pipe 32 to a container 34 for carbon dioxide under pressure and by admitting the carbon dioxide to the desired receptacle the pasty material is forced out through pipes 14, 15 and 20 to distributers 21 from which it is intermittently ejected to form flakes on the first of a series of travelling bands 46, 52, 55. The distributers comprise containers 130 for the paste fitted with discharge openings provided with closure members 137 at the end of pins 135 adapted to be pressed downwards by springs 139 and lifted to release a quantity of the material in the containers by levers 141 actuated by cams 145. The portions of paste are carried by the band 46 through a chamber in which they are subjected to heat from electric resistance elements 99, 100 and also from a current of heated air. The chamber is provided with insulated walls 81, 82. The solidified flakes are lifted from the band by a scraper 102 and fall on to the second band 52 that carries them through a drying chamber where they are subjected to hot air coming from the last or roasting chamber or directly heated by resistances 104 arranged between plates to direct the heated air through the band which is preferably of netting. Cleaning and lubricating devices are provided for the bands. The dried flakes fall on to the band 55 of the roasting compartment. This compartment is provided with a series of resistances 107 arranged between deflecting plates 85. The size of the openings 106 between the plates is such that hot air forced therethrough by a fan 69 lifts and mixes the flakes on the band 55 thus ensuring uniform roasting. The finished flakes fall on a conveyer band 56 that carries them to a packing machine. The hot air escaping from the heating chambers passes through a filter 68 to a heat interchanger 43 in which fresh air is warmed. Other heating devices than electric resistances may be used and the paste for the flakes may be ejected by pistons, spoons, ladles or the like.
