Title: Transmitting queued data packets according to priority
Inventor: NAVEN FINBAR
IPC: H04L12/54
Filed: 2007-09-18
Abstract: A method of queuing data packets, said data packets comprising data packets of a first packet type and data packets of a second packet type. The method comprises grouping received packets of said first and second packet types into an ordered series of groups, each group comprising at least one packet, maintaining a group counter indicating the number of groups at the beginning of the series of groups comprising only packets of the second packet type, and transmitting a packet. A packet of the second packet type is available for transmission if but only if the group counter is indicative that the number of groups at the beginning of the series of groups comprising only packets of the second packet type is greater than zero. Thus, the packet at the head of the bypassable queue is only available for onward transmission when the group counter is greater than zero. Aspects of the invention include the packets of a first type being ordered or higher Priority and packets of a second type being bypassable or lower priority. The method implements a bypass capable queue which preserves relative ordering of the first and second packet types and allows first packet type packets to overtake second packet type packets.

Title: Echo canceller
Inventor: TAKADA MASAHI
IPC: H04B3/23
Filed: 2006-11-24
Abstract: An echo canceller is capable of reducing echo feeling in a conversation after the input of a tone signal. The echo canceller judges if a remote input signal is a calling control tone signal, and sets a coefficient of an adaptive filter if that is the case. The other embodiment of an echo canceller judges whether a remote input signal is a predetermined kind of a tone signal and stops a renewal of the coefficient of the adaptive filter if the result is affirmative and echo consumption quantity is not larger than a threshold value. Further, when the tone signal ends, the echo canceller compares echo consumption quantities before and after the end, resets the coefficient of the adaptive filter in accordance with a comparison result and then renews the coefficient of the adaptive filter again, or renews the coefficient of the adaptive filter again without the reset of the coefficient of the adaptive filter. In addition, a band elimination filter is provided to eliminate a tone signal frequency component at input stages of the adaptive filter and the adder for the elimination of echo.

Title: Process of and apparatus for measuring reduction in size of solids
IPC: G01N15/02
Filed: 1932-04-08
Abstract: 404,608. Testing physical qualities of materials. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.- (Assignees of Hardgrove, R. M. ; 719, Highland Avenue, Westfield, New Jersey, U.S.A.) April 8, 1932, No. 10156. Convention date, April 8, 1931. [Class 106 (ii).] A process for determining the grindability of a material consists in selecting a definite weight thereof divided to a given fineness, subjecting it to a definite process of pulverization in apparatus adapted to perform a precisely determined amount of work upon it and comparing the result with that obtained by submitting a standard material to the same series of steps. The factor so obtained may be used in designing a mill to fulfil given requirements. A quantity of the material under test, of given fineness may be obtained by grinding the material in a coffee mill and selecting that part of the product which passes through a sieve of given mesh but not through one of smaller mesh.. A known weight of this is then subjected to a definite process of pulverization. This may be done in the pestle and mortar device shown in Fig. 2, in which the pestle 21 is connected by links 22, 28 to a disc 30 which is rotated by a motor 31 whereby the pestle is raised and dropped through a definite stroke. A link 26 imparts a swinging motion to the pestle so that it strikes the mortar at different points. After being subjected to a determined number of strokes the pulverized material is passed through a series of sieves of progressively increasing fineness of mesh and the weight of material that passes through each sieve is noted and from these facts is deduced a number that is proportional to the total amount of new surface produced by the pulverization. An equal weight of the standard material of equal initial fineness is treated to an identical pulverizing and screening process and the corresponding number that is proportional to the new surface produced in this case is deduced. The ratio of these two numbers gives the grindability of the material under test. The materials may be pulverized in a ball-mill instead of the pestle and mortar. In this case the balls are subject to a definite pressure by a spring or weight and the mill is driven the same number of revolutions for the two materials.

Title: Glass-ceramic articles
IPC: C03C10/00
Filed: 1969-02-26
Abstract: 1,247,243. Strengthened glass ceramics. PPG INDUSTRIES Inc. 26 Feb., 1969 [1 March, 1968], No. 10316/69. Heading CIM. A strengthened bulk crystallized glassceramic article has substantially the same composition throughout, and has a surface zone in a state of compression and an interior zone in a state of tension. Such an article may be formed substantially craze-free by maintaining the absorbed water of the surface of the article at a substantially constant concentration during the crystallization period. This is thought to prevent the reaction occurring at the surface of the article. The water concentration may be maintained during the crystallization heating by adding water to the atmosphere surrounding the article so as to substantially maintain an equilibrium. The atmosphere preferably contains about 0À1 moles water per mole of gas. The furnace may be flushed with an inert gas (e.g. N 2 ) saturated with water, or water may be added directly to the furnace. An alternative way of maintaining the surface water concentration substantially constant is to coat the article before crystallization with a water-impermeable substance. Suitable coating materials are the oxides of Si, Ti, Al, Cr, Sn, In and Fe, and the metals Ti, Cr and Pt. The coatings may be applied by any suitable technique; low temperature coating or vacuum coating are preferred. By coating with TiO 2  or ZrO 2  these materials may also act as nucleating agents. Preferably the crystallizable glass composition is one which gives a crystalline phase whose coefficient of thermal expansion is lower than the vitreous phase. A preferred composition comprises (in wt. per cent) SiO 2  45-72; Al 2 O 3  15-35; Li 2 O 3-10; preferably with 1-5 each of ZrO 2  and TiO 2 .
