Title: An input system including an interactive surface for detecting a contact point and the presence of a response to an excitation signal
Inventor: OAKLEY ANDREW
IPC: G06F3/033
Filed: 2009-12-23
Abstract: An input system includes an interactive surface (122) which may include a display and an excitation means which includes e.g. a coil (150) for generating an excitation signal. A pointing device (e.g. a stylus, fig. 3) is adapted (the stylus may contain a switchable resonant circuit or radio frequency identity tag (RFID tag)) to respond to the excitation signal. An input condition is determined in response to detecting a contact point and a response to an excitation signal. The device may distinguish between finger and pointer interaction. The pointer may include a pressure sensitive switch (figure 3, 206) so as to enable or disable a resonant circuit. The system may thereby distinguish a hover (mouse over) interaction and pen down interaction. A pointing device is also claimed.

Title: Improvements in the electrolytic production of titanium
IPC: C25C7/04
Filed: 1956-04-03
Abstract: 811,862. Electrolytic production of titanium. NEW JERSEY ZINC CO. April 3, 1956 [May 5, 1955], No. 10143/56. Class 41. In the production of titanium by electrolysis of a fused bath formed of one or more of alkali metal halides, alkaline earth metal fluorides and alkali metal fluotitanates to which is added a decomposable titanium compound, the bath being contained in a two-compartment cell divided by a perforated electrically-conductive structure, the structure is made negative to the anode and the current between is adjusted to deposit titanium on the structure until the degree of permeability required to serve as the porous barrier during cathodic deposition of titanium has been obtained, whereafter the currents flowing between anode, barrier, and cathode are controlled so that titanium is cathodically deposited while maintaining the porous titanium deposit forming the porous barrier. The perforated structure may be a drilled plate or a screen and may be of nickel or its corrosion-resistant base alloys, stainless steel, or molybdenum. A suitable cell comprises a central cylindrical graphite anode within a cup-shaped diaphragm of calendered nickel wire cloth having an impervious nickel sheet bottom and connected at its upper edge to a graphite tube serving as a vent for anodically evolved gas, the cup wall being surrounded by a cylindrical band iron-nickel cathode, all disposed concentrically within a container of the same material as the cathode. The cell is filled to just above the rim of the cup with a eutectic mixture of lithium, potassium, and sodium chlorides and titanium tetrachloride is fed to the cathode compartment. The cell may be operated at 550‹ C. in four stages, in the first of which titanium is deposited on the cup to form the porous barrier, in the second stage the rate of addition of titanium tetrachloride is increased to build up a desired concentration of lower titanium chlorides (e.g. the dichloride) in the catholyte, cathodic deposition of titanium with simultaneous addition of titanium tetrachloride being effected in the third stage while this addition is stopped in the fourth stage to allow stripping of the titanium compounds from the bath. At the end of this the cup and anode assembly and the cathode are raised from the bath to drain off the salt and when the cell has cooled to bring the cathode deposit to 200-250‹ C. the cathode cup and anode are removed from the cell. Typically the bulk of the cathode deposit has a particle size of above 44Á. and an ingot prepared from it has a Rockwell A hardness of 35. In operating the cell the chief guides in the necessary control of the current are the escape of titanium tetrachloride with the anodically evolved chlorine, indicating that the porous barrier is insufficiently impervious to the flow of electrolyte, and the back voltage developed.

Title: Beta-chloroethyl beta-chloroethoxy-ethyl ether
Filed: 1935-04-02
Abstract: Beta - chloroethyl beta - chloroethoxy - ethyl ether (or triethylene glycol di-chloride) having the formula ClCH2.CH2.O.CH2.CH2.O.CH2. CH2Cl is obtained by reacting ethylene, chlorine and ethylene oxide, preferably in the presence of water and isolating the ether from the reaction mixture.  Ethylene chlorhydrin may also be added to the reaction mixture.  Temperatures of about 20--100 DEG  C. may be employed.  According to an example ethylene and chlorine are bubbled through a body of water in a closed container, the gases being uniformly introduced through diffusers. Ethylene oxide is also passed through the liquid at a rate sufficient to maintain the liquid slightly acid.  The unexhausted gases may be recycled in the process. Water is added occasionally to prevent depletion of chlorhydrin content of the liquid.  When sufficient reaction products have accumulated all or a portion of the liquid may be treated with water with a resulting separation into two layers.  The upper layer is returned for further treatment while the lower layer is washed with water to remove a part of the chlorhydrin and is then subjected to fractional distillation, preferably under sub-atmospheric pressure. The fraction distilling at 118 DEG  C. at 10 mm. pressure contains the beta-chloroethyl beta-chloroethoxyethyl ether.  The compound may be purified by a further distillation under sub-atmospheric pressure. Alternatively the distillation may be effected without the prior separation of an aqueous layer.  The compound may be employed as a solvent in the production of lubricants or as a solvent for the extraction of oils or hydrocarbons.  Specification 438,271 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the production of beta-chloroethyl beta-chloroethoxy-ethyl ether by a reaction between ethylene chlorhydrin, ethylene and chlorine, preferably in the presence of water or by a reaction between water, chlorine and ethylene.  This subject-matter does not appear in the Specification as accepted.ALSO:Triethylene glycol dichloride having the formula <FORM:0456278/III/1> is employed as a solvent in the production of lubricants or as a solvent for the extraction of oils and hydrocarbons.

Title: Improvements in or relating to selector arrangements
Inventor: HAMMANS BRYAN
IPC: G06V30/162
Filed: 1968-03-04
Abstract: 1,247,865. Character recognition. MARCONI CO. Ltd. 14 Feb., 1969 [4 March, 1968], No. 10377/68. Heading G4R. An input selector arrangement for indicating which of a plurality of inputs receives the most pulses in a given time period, and if more than one input receives the maximum number for indicating the median input midway between the extreme inputs which received the maximum number, has an individual counter for each input which counts its pulses, the counters then being counted up by clock pulses until one reaches capacity, the counter or counters reaching capacity at that time setting respective stages in register means, the number of unset stages between the ends of the register means and the set stages nearest the respective ends being determined to indicate the required input. In character recognition apparatus, the arrangement is used to determine the threshold to be used for digitizing the outputs of a matrix of scanning photo-cells, the output of one photocell being passed through 6 threshold devices having different thresholds, in parallel, to feed respective inputs of the above arrangement, the time period being " character begin " to " character end." The register means is two registers, each counter reaching capacity setting a respective stage in both registers. One register is then shifted to the left, the shift pulses being counted up by an auxiliary counter (preset to 7 at " character begin "), until a 1 (set) reaches the end of the register when the other register is shifted to the right, the shift pulses being counted down by the auxiliary counter, until a 1 reaches the end of this register. The stages of the auxiliary counter, which is binary (as are the other counters), are decoded, excluding the lowest order stage, to indicate the required input (threshold). In a modification, any counter reaching capacity during the time period referred to is set to and held at zero, it being assumed that reaching of capacity was due to noise. By using one or more extra auxiliary counters, both registers could be shifted simultaneously. Alternatively, a single register could be used.

Title: Means for indirect forced commutation of static current converters in two-way connection
IPC: H02M7/00
Filed: 1946-04-04
Abstract: 610,392. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 4, 1946, No. 10393. Convention date, April 21, 1945. [Class 38 (ii)] For commutation in converting arrangements in which a pair of main valves are oppositely connected to each A.C. terminal and in series across the D.C. terminals, a pair of transition valves are connected to each pair of main valves without any intermediary transformer winding. The three A.C. phases 8 are connected to the junctions of pairs of oppositely connected valves 1, 4; 2, 5; 3, 6; which are also connected across D.C. circuit 7. Pairs of transition valves 11, 14; 12, 15; 13, 16 are also connected across the D.C. circuit, their junctions being connected to the A.C. terminals through commutating condensers 17, 18, 19. When commutating from valves 1 to 2, valve 11 is ignited so that condenser 17 discharges through valves 1 and 11 to transfer suddenly the load to valve 11, and then condenser 17 is charged in the opposite direction, the load being gradually transferred to the now ignited valve 2. Condenser 17 is left charged in the reverse direction ready for commutation from valve 4 to valve 5 by way of valve 15 in the reverse half-cycle of the same phase. Normally the time of commutation can be extended to recharge the condenser even during low load, but if necessary an additional valve and reactor may be associated with each valve, e.g. 22, 20 with valve 1 or 25, 24 with valve 3, for this purpose. A modification is described in which the junctions of each pair of transition valves are connected to the A.C. phase, and a condenser is connected between the other ends of these valves and the junction of another pair of valves connected in series across the D.C. circuit, so that only one commutation condenser is used. Since each commutation cannot be extended over more than 1/6th of a cycle to meet load fluctuations, auxiliary discharge circuits or a further condenser may be provided, Fig. 2 (not shown). The transition valve connected to the incoming main valve (especially in rectifiers) or even the third valve may be used to effect the commutation.
