Title: Identifying the source of a memory leak by grouping repeated patterns of the same object type
Inventor: BAILEY CHRISTOPHER NEIL
IPC: G06F11/36
Filed: 2009-09-07
Abstract: Repeated patterns of the same object type are identified in a collection of dynamic data structures, such as a Java® object heap. The objects are then grouped together in a flat data structure and analysed to using a memory leak detection algorithm. The objects that are identified may form a linked list and some of the nodes may be ancestors of other nodes. The sizes of the nodes may be calculated and a memory leak may be detected by finding a child node which is smaller than its parent. Alternatively, the number of child nodes may be calculated and a memory leak identified if a node has a large number of child nodes. The objects may be in a memory image.

Abstract: 1490402 Vibration measurement COMMISSARIAT A L'ENERGIE ATOMIQUE 11 March 1975 [19 March 1974] 10129/75 Heading G1G Mechanical vibrations in a medium are measured with a transducer operating on magneto-hydrodynamic principles. In the Fig. 1 embodiment for use in a sodiumcooled nuclear reactor, liquid Na or Na-K, 9, partly fills a hermetically-sealed stainless steel vessel 2 within the coolant. Alternating flow of liquid 9 in a channel 6 occurs in response to the vibrations. A steady or alternating magnetic field H 1 , H 2  is applied at right angles to the flow direction by a permanent magnet 12 or electromagnet, Fig. 6 (not shown). A voltage waveform generated in a direction at right angles to both the flow and magnetic field directions is picked off by electrodes 14 for display or recording on a screen. In the Fig. 5 (or 4) embodiment the alternating flow occurs in the annular space around a sheath 20 containing a former 15 on which is wound a primary coil P flanked by two secondary coils S 1 , S 2  connected in opposition. Coil P is AC energized and induces voltages across coils S 1 , S 2  which voltages are balanced in the absence of liquid motion but which provide a nett difference voltage output when motion occurs in response to the vibrations. For applications other than in nuclear reactors the liquid in vessel 2 may be an aqueous electrolyte (e.g. boric acid) solution.

Title: Improvements in or relating to reproduction of dyeings
IPC: G01J3/52
Filed: 1960-03-22
Abstract: The colour of a dyeing of an original dye mixture on a carrier is reproduced by separately applying a number of primary colour dyes in a plurality of dyebath concentrations to a plurality of samples of the same dye carrier to be dyed, determining from these dyed samples their spectral reflectance curves, determining the spectral reflectance curve of the original dye mixture, selecting from the spectral reflectance curve of each particular primary colour dye the particular wavelength at which the ratio of the reflectance of that particular primary colour dye to the reflectance of the other primary colour dyes is a minimum, tracing graphically for each of those selected wavelengths the reflectance values of all the primary colour dyes as a function of the dyebath concentration, determining from these graphs the dyebath concentrations of the individual dye components of the dye mixture required to reproduce the colour of the original dye mixture at the reflectance values of the original dye mixture corresponding to the said particular wavelengths, mixing the dye components in a dyebath at the determined dyebath concentrations and dyeing the carrier from this dyebath.  The reflectance curve of the reproduced dyeing is determined and compared with the reflectance curve of the original dye mixture and the dyebath concentrations of the dye components are then corrected according to the differences in the reflectance values at the wavelengths at which they were determined.

Title: A new high-frequency method for the preparation of colloidal solutions
IPC: B01J13/00
Filed: 1923-04-16
Abstract: Colloidal solutions of metals and non-metals are prepared by passing an alternating current of frequency 100,000 to 850,000 per second between electrodes of the metal or non-metal in water or other liquid dispersion medium.  If water be employed its hydrogen-ion concentration should be between pH 5.8 and pH 6.2, which may be attained by passing oxygen through water distilled once only.  The high frequency currents may be generated by any of the known methods for wireless transmitters of spark, arc, or valve design.  In an example silver is dispersed in water.  The solutions obtained are stable and may be concentrated by passage through porcelain filters at high pressure, or by boiling.

Abstract: 179,912. Biemer, H. May 7, 1921, [Convention date]. Padlocks; revolving-barrel locks; locks, wards for.-A padlock has a rotatable cylinder arranged in a bore in the solid metal casing and adapted to move, by means of the inclined faces of notches in its end, the bolt to lock the shackle. The bolt f<4> has an arm f<5> and slides in a guide-piece f having two bores f<1>, f<2>, one for housing the spring f<6> and one for the bolt, connected by a slot f<3> in which slides the arm f' upon which the spring f<6> acts.

Within a bore in the cylinder is fitted a spring-pressed pin k having a notch k<1> exactly fitting the head of a spring-pressed pin m at right-angles to the pin k. The tail end of the pin m engages recesses a<1> in the casing when the padlock is locked or unlocked. Two closing sleeves h and i form wards for the key. Fig. 1 shows the padlock in the locked position. To unlock, the key, Fig. 6, is inserted through the holes p of the sleeves h, i so that the leg r enters the slot g<6> in the cylinder and the leg q depresses the pin k until the head oi the pin m enters the slot k<1>.
