Title: Detecting display of content, such as a web page, using identifier codes
Inventor: MCKNIGHT THOMAS R
IPC: G06F11/34
Filed: 2009-11-18
Abstract: Visual content data, such as a web page, is encoded with two or more identifier codes or markers 206, 235 and received at a computer device. Resulting visual display data is transmitted, using a local communication bus of the computer device (114, Figure 1), to a visual display device (120) coupled to the computer device (110). A processor on the computer device is used to determine whether the visual display data includes the encoded identifier codes, and exposure information is generated using the processor. The exposure information is associated with whether the encoded identifier code is included in the visual display data. The exposure information is transmitted, from the computer device, to a remote server device (140). Two or more visual objects may be associated with the identifier codes; horizontal or vertical object positions may be associated with ID codes. Thus, the visual display of content actually viewed — rather than just received — and the viewing time duration or view area size may be measured.

Title: New substance with action on the respiratory centre, and process for preparing it synthetically
IPC: C07D233/64
Filed: 1953-04-13
Abstract: The invention comprises salts of a base whose cation has the formula <FORM:0733576/IV (b)/1> and which may be considered as the esterification product of b -imidoazolyl-4 (or -5) acrylic acid and b -hydroxy-ethyl trimethyl ammonium.  Salts can be obtained with two equivalents of acid radical in view of the basic 1- and 3-nitrogen atoms in the imidoazole ring.  The salts have an exciting action on the respiratory centre or in heavier doses a curare-like effect, and the free base is termed, in the Specification, "murexine."  The salts are prepared by treating the 2-chloroethyl ester of a -chloro-b (imidoazolyl-4(5)) propionic acid in hot solution, preferably in an apolar solvent, in an autoclave with trimethylamine to give the chloride.  This is converted into the picrate which may be converted into another salt by boiling with a salt of a cationic detergent.  In the example the dipicrate of murexine, obtained as above, is reacted in boiling aqueous solution with the dihydrochloride of 2,4-diguanidine phenyl lauryl ether, precipitating the ether-dipicrate and forming murexine chloride-hydrochloride.

Title: Method and apparatus relating to loading and separating rollers  of a calender
IPC: B29C43/22
Filed: 1972-03-03
Abstract: 1361565 Calenders BRUDERHAUS MASCHINEN GmbH 3 March 1972 10094/72 Heading D2A In a super-calender having a vertical stack of rollers, the rollers are loaded by downward movement of pistons 16 of rams 14 acting on the top roller 2" while the bottom roller 2' is maintained in its operative position by pistons 11 of rams 9 moved upwardly against a stop 13 and acting on the bottom roller, and the rollers are separated, e.g. in the event of web breakage, by upward movement of the pistons 16 and downward movement of the pistons 11, the latter movement occurring when the force exerted by the pistons 16 corresponds substantially to that necessary to lift the top roller. The rollers consist of hard and resilient rollers alternating with each other and rotatably mounted in side plates 3 which are slidably mounted on a frame 4. Threaded spindles 6 carried by the top side plates 3" slidably engage in aligned lugs 5 on the other side plates, except the bottom side plates 3', and carry adjustable nuts 8 for engaging the lugs 5. The travel of the piston 11 is equal to the sum of all the gaps between the rollers when these are lifted. In a hydraulic circuit, Fig. 2 (not shown), magnetically operable valves control fluid flow from a first pump to the bottom sides of the pistons 11 and 16, and from a second pump to the top side of the pistons 16. The bottom roller 2' is lowered by draining fluid from below the pistons 11 through valves which are under the control of rams operating to mechanically unseat closing members of the valves in dependence upon the pressure of the fluid below the pistons 16 reaching that necessary to lift the top roller 2". When a limit switch 32 senses that the bottom roller 2' and the adjacent roller are separated it causes the upward movement of the pistons 16 to stop.

Abstract: 780,979. Microwave circuits. BRITISH THOMSON-HOUSTON CO., Ltd. April 25, 1955 [April 6, 1954], No. 10097/54. Class 40 (8). Two transmission lines 1, 2, e.g. waveguides, are coupled at two points 3, 4 spaced apart along the length of each line by unequal electrical distances. For this purpose the physical distances between the couplings may be different or the physical distances may be the same and the cross-sections of the guides different. If the path difference is arranged to be an integral member of half-wavelengths at a desired frequency then energy at this frequency fed to one of the inputs A, D will all appear at one or other of the outputs B, C. Energy of other frequencies will be divided in varying proportions between the outputs. The couplings may be of the 3 db. slot-type, as shown, or may be of the "rat-race" or Magic-T type. The circuit may be coupled to a magnetron oscillator in such a manner that energy is diverted from the load when the magnetron oscillates in an undesired mode. Specifications 619,521 and 673,957, [both in Group XL (c)], are referred to.

Title: Electron beam specimen analysis
IPC: H01J37/256
Filed: 1971-04-20
Abstract: 1388110 Scanning electron microscope image analysis IMAGE ANALYSING COMPUTERS Ltd 11 April 1972 [20 April 1971] 10288/71 Heading G4D [Also in Division G1] In the analysis of specimens by, e.g. a scanning electron microscope, metallic inclusions are identified as such by a signal representative of the sensed specimen current from 16 exceeding a reference level set in comparator 20, and the resulting signals which occur at 24 used (direct or after, e.g. skrinking, stretching &c), to gate at 30 the output of, e.g. a sensor of X- rays 18. The X-ray probe may be an X-ray spectrometer in which case the wavelength of X-rays to be detected may be chosen at 19 so that the signals gated for further processing are representative of a particular metal only. The invention is generally applicable to analysis by scanning with an electron beam and the gated signals may alternatively be due to backscatter, cathode luminescence, secondary electron emission, specimen E.M.F. and direct transmission; the object is to increase scanning speeds.  The reference level 22 may be simply to differentiate a metallic inclusion from background noise, but could theoretically also be used to discriminate between metals, if these produce differing amplitude levels. While the reference voltage is being adjusted, the number of line scans per field scan is reduced. The circuit of Fig. 4 is designed to determine one particular metal in a field which may include inclusions of other metals (see e.g. features 10, 12 of different metals, Fig. 1). The wavelength 7 characteristic of the particular metal is selected at 19. However, pulses will be gated at 30 not only within the feature predominantly of the particular metal but to a lesser extent within the other features. To differentiate between these features the ratio N/A is calculated at 44, where N is the number of X-ray pulses for each feature calculated by computer 38 and A is the area of each feature. If N/A is within range JK, the feature is of the required metal. The number of features in the field having the required N/A value are counted at 48. Also calculated are the total X-ray pulse count for a field #N, the total area #A and the average N/A value #N/A (for a given #). In a modification, Fig. 7, not shown, two wavelengths are selected simultaneously so that two types of metal may be determined, there being provided two channels, each comprising an amplifier, number N computer, divider and comparator, a common area computer being sufficient to operate with both the channels. Accumulators for #A for the two wavelengths are provided.
