Title: Sorting items into receivers
Inventor: BJORNSSON YNGVI
IPC: B07C5/00
Filed: 2009-08-19
Abstract: Allocating items in a group of items into receivers in a group of receivers wherein the characteristic property information of the group of items and capacity information of the group of receivers are obtained. Using the characteristic property of a first item and a selected second item within the group of items the possible options for allocating the first and second items analysing are determined. By taking into account of the respective capacities of receivers in the group of receivers the receiver can be determined for the allocation of the first item. A plurality of items can be checked before sorting the first item. The capacity information for the group of receivers may include the current fill level and a target fill level for one or more of the group of receivers. The step of considering possible options for allocating said first and second items to a group of receivers includes comparing a resulting fill level to a respective target fill level for each receiver. The allocation of an item into a receiver can be discontinued if the receiver capacity is found to be unfavourable on addition of the item.

Title: Adaptive partitioning of traffic among communications channels without injecting probe traffic
Inventor: KARACALI-AKYAMAC BENGI
IPC: H04L69/14
Filed: 2009-09-24
Abstract: A method for adaptively and intelligently partitioning traffic among a plurality of communications channels, without injecting probe traffic into any of the channels. A source node transmits traffic to a receiving node viaKcommunications channels in accordance with partition coefficients α1to αKand the source node receives information regarding the quality of service (QoS) provided by each of the communications channels. The source node adjusts the values of the partition coefficients α1to αKadaptively based on: the current channel QoS information, prior channel QoS information, the prior values of α1to αKand a measure of channel independence for one or more pairs of communications channels. This method allows traffic to be partitioned among the communications channels so as to maximise performance without injecting additional probe traffic which would increase the traffic and reduce throughput.

Filed: 1922-04-12
Abstract: 192,647. Schiff & Stern, and Gascho, J. April 12, 1922. Steam-traps.-In a steam-trap or the like in which liquid is expelled from a tank by steam or gas pressure a chamber c is interposed between the steam inlet valve e and the tank a, and communicates with the latter bv means of a throttling device so that equalization of pressure occurs before the main steam valve e opens. The valve e is secured to a plunger f which leaves a constricted passage through the port b when the valve e is closed. The lever n, actuated by the float l raises the valve k and opens the passage i in the valve e. Steam escapes past the plunger f, raising the pressure in the tank until the pressure of the spring h raises the valve e and plunger f, allowing a free passage for the steam through the port b. When the port k only is open, steam passes through the passage o exerting pressure on the plunger q to close the valve r. The float, in falling, strikes the stop s on the rod t closing the valves k, e and opening the valve r, the shorter arm of the lever n striking the collar on the valve-rod.

Title: Improvements in or relating to arrangements for generating oscillatory electric currents of saw-tooth wave form
IPC: H03K4/28
Filed: 1940-06-20
Abstract: 542,032. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 20, 1940, No. 10610. Convention date; June 30, 1939. [Class 40 (v)] In circuits for generating saw-tooth currents in an inductive load, particularly those of the kind described in Specification 400,976 in which the return stroke is effected by virtue of the reactive properties of the load which is shunted by a damping tube, the wave-form is improved by varying the impedance of the damping tube in accordance with the output of the generator. The current from the valve 1 divides between the load 2 and the tube 3, the impedance of which is varied by the voltage across a resistance 6 through which the total alternating current output of the valve passes. The current through the tube 3 may be controlled by a biasing voltage developed across the network 13, 14. In modification (1) the valve 1 may be connected through a transformer to the load and damping tube, the impedance of the latter being determined (a) by the voltage across a resistance in the primary circuit of the transformer, Figs. 2 and 5 (not shown), or (b) by the voltage across a resistance in the cathode circuit of the valve, Fig. 4 (not shown) ; (2) the damping tube may lie across the primary circuit of the transformer and the load in the secondary circuit, Fig. 3 (not shown); (3) the load may be connected directly to the valve, the damping tube being connected through a transformer, Fig. 5 (not shown). The valve 1 may be supplied with an input voltage of a slightly logarithmic wave form.

Title: A method for the production of industrial mixtures of carbon monoxide and hydrogen
IPC: C01B3/30
Filed: 1947-04-21
Abstract: A mixture of carbon monoxide and hydrogen in suitable proportions for hydrocarbon synthesis is obtained by contacting a hydrocarbon gas such as methane at a temperature above 1600 DEG  F. with a mixture of iron oxide and free iron in the form of a fluidized solid, such that there is at least 1/6 and preferably one gram atom of free iron present per gram atom of oxygen and that the atomic ratio of oxygen to free and combined iron is between 0.5 and 1.25 to 1.  These proportions are maintained by circulating the finely divided iron:iron oxide mixture from reaction zone 1 via pipe 9 through an oxidizing zone 12, from which <PICT:0634933/III/1> regenerated iron oxide returns, mixed with the incoming hydrocarbon gas entering at 34 through pipe 5, to the reaction zone.  An oxidizing gas such as air, steam or carbon dioxide enters from pipe 33.  In a modification the major part of the fluidized solid is circulated through an oxidizing zone 12 as before and a minor part is withdrawn from the reaction zone via line 21 to a reducing zone 25 fed with reducing gases from line 35 or with the exit gases from the oxidizing zone, the reduced oxide passing via pipe 30 to join pipe 5 and hence back to the reaction zone.  The hydrogen content of the product gases withdrawn at 3 may be enriched if steam is used in the oxidizing zone by the hydrogen rich exit gases from this zone.  A refractory light carrier such as magnesium or aluminium oxide may be mixed with the ferrous mixture to improve fluidization and prevent agglomeration.

Title: Interconversion of stereoisomers
IPC: C07F7/21
Filed: 1976-03-17
Abstract: 1535364 Interconversion of stereoisomeric cyclosiloxanes DOW CORNING CORP 17 March 1976 [2 June 1975] 10664/76 Heading C3S A cyclosiloxane is converted from one stereoisomeric form to another stereoisomeric form by a method which comprises contacting in a reaction zone, generally at a temperature of from room temperature to 250 C., a cyclosiloxane which is capable of forming cis and trans isomers with an anhydrous catalyst which is a compound of the formula MX n  where X is Cl or Br, M is a zinc, iron or aluminium atom and n is the valence of M or an aryl phosphonium halide, in a solvent which is an organic nitro compound or an aryl phosphate ester under conditions where such conversion will take place without appreciable distribution of the siloxane structure. The amount of catalyst is generally from 1-50 mole per cent based on the moles of cyclosiloxane, and the amount of solvent is generally above 10% wt. based on the weight of the cyclosiloxane. The isomer separation can be done either by distillation, crystallization or solvent extraction either continuously or batchwise. The reaction mixture may be removed from the reaction zone, the desired isomer separated and the undesired isomer returned to the reaction zone for further interconversion. The cyclosiloxane must have 2 different substituents, bonded to the Si through Si-C bonds, on at least 2 Si atoms in the molecule. The substituents include monovalent hydrocarbon radicals, e.g. alkyl, alkenyl, cycloaliphatic, aryl and aralkyl hydrocarbon radicals, and halogenated hydrocarbon radicals. The substituents are preferably phenyl and methyl radicals or 3,3,3-trifluoropropyl and methyl radicals. Suitable solvents include aliphatic, cycloaliphatic and aromatic nitro compounds, e.g. nitromethane, -propane, -butane, -octane, -cyclohexane, -cyclopentane, -methylcyclohexane, -benzene, -toluene, and -p-chlorobenzene, and dimethyl bis-(nitrophenoxy)silane, and triphenyl phosphate, tricresyl phosphate, tri-(isopropylphenyl)phosphate, trisnitrophenyl phosphate, butyldiphenyl phosphate and trischlorophenyl phosphate. Suitable aryl phosphonium halide catalysts are triphenylphosphonium chloride, benzyl triphenylphosphonium bromide, naphthyltriphenylphosphonium chloride, betaphenylethyltritolylphosphonium chloride and xenyltriphenylphosphonium bromide. In the examples any of the following transisomers is converted to the cis-isomer by the above method:- 2,6 - trans - diphenylhexamethylcyclotetrasiloxane, trans - triphenyltrimethylcyclotrisiloxane, trans - tris - (3,3,3 - trifluoropropyl)trimethylcyclotrisiloxane. Also transtetraphenyl - tetramethylcyclotetrasiloxane is converted into the cis isomer and the other 2 trans isomers; and 2,6-cis-diphenylhexamethylcyclotetrasiloxane is converted into the trans isomer.
