Title: Mains adaptor with feedback
Inventor: CHUN WANG KUAN
IPC: G05F1/46
Filed: 2009-03-10
Abstract: A power supply has a main body that is connected to an electrical device by a wire set 22 that includes high and low level wires 221,223 and a feedback wire 27. A voltage sensor and feedback unit 24 is provided for measuring the voltage difference between the high and low level wires and the resultant measurement is converted into an electrical signal which is fed back to the main body via the feedback wire 27. The feedback wire can transmit a fault signal indicating that the voltage difference is outside a range stored in a memory 26 and in that event a switch 25 in the feedback unit and a switch in the body (fig 3, 36) can open to interrupt power and a light emitting diode (fig 5, 21) can indicate a fault. The feedback unit can include a clock generator that changes the timing of the transmitted signals when the voltage difference is outside the range. The duty cycle of a PWM signal applied to a feedback loop can be adjusted to compensate for deviation from a preset voltage difference. The main body can include a voltage transformer and provide an output voltage selected from plural distinct output voltages. The power supply may be used to power electronic devices such as mobile phones, laptop computers and game players from an AC wall socket.

Title: Analysis and classification of biological or biochemical objects on the basis of time-lapse images
Inventor: JOANIDOPOULOS KONSTANTIN
IPC: G06K9/46
Filed: 2009-11-30
Abstract: The invention relates to a method for the analysis and classification of objects of interest, for example biological or biochemical objects, on the basis of time-lapse images, for example for use in time-lapse analysis in image-base cytometry. Images of the objects of interest, for example cells, are recorded at different moments in time and these images are subjected to a segmentation process to identify image elements as object representations or sub-object representations of objects or sub-objects of interest of objects of interest. Identified object representations or sub-object representations are then associated with one another in images of the time series and are identified as representations of the same object or sub-object or as the result of an object or sub-object. First features manifesting themselves in individual images are detected and second features manifesting themselves in a plurality of images recorded at different times are detected. The individual objects or sub-objects identified in the digital images of the series are classified on the basis of at least one classifier relating to at least one second feature, and this classification process is used as the basis for or as part of a further analysis process in relation to at least one query of interest.

Title: Improvements in actuating and transfer arrangements for calculating and counting apparatus
IPC: G06C15/38
Filed: 1931-04-02
Abstract: 366,343. Counting-apparatus. OCHSENBEIN, W., 7, Landhausweg, Berne, Switzerland. April 2, 1931, No. 10032. [Class 106 (i).] In cam-disc and pin-wheel actuating-mechanism, applicable to franking-machines, the counting train is normally locked by a detent lever controlled positively at all times by the pins and by a rim on the pin-wheel. The transfer arrangements are also such that movement of a counting- wheel can only take place at transfer and during actuation. Detent mechanism.-As shown in Fig. 1 the radially movable teeth 3 of the pin-wheel 2 actuate the counting wheel 8 through a pinion 6 which however is normally locked by a detent lever 26 formed with two cam surfaces 30, 31 receiving between them a rim 5 on the actuating wheel 2. At actuation a set tooth 3 rocks the detent lever counterclockwise to unlock the wheel 6 which may then be turned by the tooth. The locking lever is pivoted at 25 on a verticallyslidable bar 24 pin-and-slot connected at 20 with a lever 19 cut-out at 17 to receive a triangular block 16 forming part of the Geneva transfer elements of the lower denomination. Thus at transfer the rotation of the block permits descent of the bar 24 and therefore of the lever 26 and the release of the higher wheel 6 for receiving the transfer. Transfer-mechanism.-In the form shown in Fig. 8 the locking-lever 26<1> is pivoted on a stationary axis 25<1> and is controlled as before by the teeth 3 and also by a further tooth 141 effective at transfer only. When a lower wheel passes from 9 to 0 a tooth 19<1> displaces a lever 18<1> so that its cam surfaces 11<1>, 12<1> permit the transfer operating tooth 14<1> to engage and advance the higher pinion 6. Otherwise the cams occupy the position shown and restrain the tooth 141 from action. The lever 181 is restored by a pin 17<1> fixed on the pin-wheel. The lever is retained in either position by a pawl 231 a weighted tail 241 of which co-operates with the pin 17<1> of the next lower denomination. In a modification, Fig. 16, a further cam surface 32 is provided on the lever 18<1> to co-operate with a pin 34 on the actuating-wheel the arrangement being such that no movement of the lever is possible during the passage of pin 141.

Title: Method of making a semiconductor device having two insulating coatings
IPC: H01L21/00
Filed: 1967-03-03
Abstract: 1,142,405. Etching. RADIO CORPORATION OF AMERICA. 3 March, 1967 [8 March, 1966; 9 June, 1966], No. 10304/67. Heading B6J. [Also in Division H1] In the manufacture of semi-conductor devices a coating of a first insulating material is formed on a semi-conductor body, and a pattern of openings formed in it. A coating of a second insulating material is then formed over the first coating and in the openings and a corresponding pattern of openings, formed in it by treatment with an etchant which etches the second insulating material at least twice as fast as the first. In a typical case using a silicon body the first coating is thermally grown silicon oxide and the second coating silicon oxide deposited pyrolytically from a silane and oxygen atmosphere. The pattern of openings is formed in both layers photo-lithographically using a specified etchant consisting of ammonium fluoride, hydrofluoric acid and water. Impurity is diffused in through the first openings and the areas exposed by the openings in the second layer are metallized after etching or pre-doping, or merely etched or rendered more conductive by impurity diffusion. Where the body is of silicon, germanium or gallium arsenide other suitable materials for the first coating are titanium carbide, silicon carbide, silicon oxynitride, and silicon nitride produced by reaction of ammonia and silane. Silicon monoxide, magnesium oxide and hydroxide and silicon oxide formed by the thermal decomposition of siloxanes are suitable for the second coating. Both coatings may include dopant materials if desired.

Title: Improvements relating to the operation of supercritical pressure vapour generators
IPC: F22B29/08
Filed: 1955-04-07
Abstract: 768,214. Critical pressure boilers. BABCOCK & WILCOX, Ltd. April 7, 1955 [April 8, 1954], No. 10325/55. Class 123(2). A forced-flow, once-through steam generator producing steam at supercritical temperature and pressure comprises a preheater section 12a, a primary superheater 12b, a normally-dry separator drum 22 and a secondary superheater 12c arranged for serial flow of fluid therethrough. A feed pump 18 supplies water to section 12a at supercritical pressure, e.g. 5,000 lbs. per. sq. in., the water leaving the section at about 680‹F. and passing to superheater 12b through an unheated external transfer line 20. During normal operation, the water-steam conversion zone 12d is located in superheater 12b. Steam leaves the superheater and flows through drum 22, the secondary superheater wherein it is heated to about 1/100‹F. and the outlet valve 26 of the latter to the point of use. When it becomes necessary to remove scale from zone 12d this is carried out whilst maintaining a supply of steam from the generator by first reducing the generator pressure to below the critical, e.g. to 2;600 lbs. per sq. in., by opening valve 26 so that steam separates in section 12a, the steam-water mixture flowing through superheater 12b and removing some of the scale The water in the mixture is completely evaporated in superheater 12b and the scale particles are washed from the steam leaving the superheater by pure water admitted from line 28, the steam separating from the wash water in drum 22 and flowing through superheater 12c wherein it is raised to the correct temperature. When the lower pressure is reached, the firing rate is decreased to cause the conversion zone to move from section 12a through superheater 12b into drum 22. The water now flowing through superheater 12b flushes the remaining scale from zone 12d into drum 22. Scalecarrying water is drained from the drum through a line 32 and a reducing valve 34 into a receiving tank 40 provided with a blow-down valve 44 operated according to the level in the tank by a controller 42. The blow-dowri water passes through a cooler 48 and purifier 52 to the feed water storage tank 60. When the scale-forming zone 12d is clean, normal supercritical pressure operation is resumed. During flushing, a special scale-removing liquid such as caustic soda solution may be injected into conduit 20 at 62.

Abstract: 252,136. Worthingtan Pump & Machinery Corporation, (Assignees of Benson, H. F.). May 18, 1925, [Convention date]. Multi-stage helico centrifugal pumps; casings; impeller blades.-In a centrifugal pump,. more particularly adapted to work as a deep well multi-stage pump, the impeller of each stage delivers the stream, in an advancing flow rotating about the pump axis, to an annular vane-free whirl chamber from which it passes to a vane-equipped diffuser giving an axial outflow. Two stages are shown in Fig. 1, the impellers 12 being carried by the shaft 10 which extends down through the drop pipe 11. Guide vanes 15 are provided below the pump sections to impart a true axial flow to the water rising to the impeller. Each impeller has a conical core 17 and a peripheral shroud 18 with vanes 21 between them. The vanes 21 start at the inlet end 19, Fig. 3, in a plane at right-angles to the axis, their inlet edges being curved as shown; the vane surfaces pass gradually towards. the outlet end 21 with a gradually increasing warp until the outlet edges 21<1> are presented at oblique angles to the axis. The largest radius of the inlet 19 is approximately equal to the smallest radius of the outlet 21. The difference between the maxmum and minimum radii at the outlet is less than at the inlet. The water passes from the impeller into the vaneless whirl chamber 14 formed by the casing unit 29; from that chamber it passes to the fixed diffuser 13, which has an increasing cross-sectional area in the direction of flow and is provided with vanes 40, Fig. 6, with the entering edges 40<1> bent into the direction of the approaching liquid and the leaving edges 41 arranged to give an axial flow. The vanes are secured to the central conical portion 34 and an outer ring 35.
