Title: Improvements in or relating to tracking devices
IPC: G01S3/787
Filed: 1957-06-24
Abstract: 846,931. Photo-electric direction-finding apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 24, 1957 [June 26, 1956], No. 19891/57. Class 40(3). Apparatus for measuring the elevation and azimuth of a distant luminous object comprises an optical system having lens 1, an electric circuit having a light transducer 4 and a screen 2 rotatable about the optic axis in a plane other than the focal plane and having a circular hole 3 whose circumference passes through the optic axis. The amount of light falling on the transducer varies as the screen rotates and the elevation α is determined by the ratio of the maximum to the minimum light falling on the transducer and the azimuth # by the phase of the maximum light. The screen 2 may be arranged between the lens 1 and its focal plane as shown or between the focal plane and the transducer and a chopper in the form of a rotating slotted disc may be provided in the focal plane. The output of the transducer which may be a photo-electric cell is applied to the circuit shown in Fig. 13. The cell is connected to the grid of a triode 101, the anode of which is connected through a capacitor 105 to the anodes and cathodes of triodes 106-109 connected together and in circuit with high resistances 110-114 as shown. A pulse generator 118 supplies positive pulses to the grids of tubes 106, 107 when the screen 2 is in its initial position and to the grids of tubes 108, 109 when the screen has rotated through 180 degrees and the output of the tubes 106-109 is applied to a comparator 117. A similiar circuit 119 is operated at 90 degrees and 270 degrees and its output applied to another comparator. The signals of the comparators are combined to give the elevation and azimuth of the distant luminous object.

Filed: 1967-05-01
Abstract: 1,176,690. Hydrofining. UNIVERSAL OIL PRODUCTS CO. 1 May, 1967, No. 19927/67. Heading C5E. A process for hydrorefining a hydrocarbon mixture containing hydrocarbons boiling above the gasoline boiling range, and containing at least one contaminant selected from sulphurous compounds and nitrogenous compounds comprises (a) hydrocracking and hydrorefining a first hydrocarbon feed stream comprising all or part of said contaminated hydrocarbon mixture with a gas containing hydrogen at a temperature of from 600‹ to 850‹ F. in a first reaction zone containing a hydrorefining catalyst, (b) separating the resulting normally liquid product into a first light fraction having an end boiling point in the range of from 400‹ to 650‹ F., and a hydrorefined first heavy fraction, (c) combining at least a portion of said first light fraction with a second hydrocarbon feed stream optionally comprising a part of said contaminated hydrocarbon mixture, said second feed stream having an initial boiling point in the range of from 300‹ to 450‹ F. and reacting the combined stream with a gas containing hydrogen at a temperature of 600‹ to 850‹ F. in a second reaction zone containing a hydrorefining catalyst, (d) separating the resulting normally liquid product from said second reaction zone into a second light fraction having an end boiling point within the range of from 300‹ to 450‹ F., and a hydrorefined second heavy fraction, (e) combining at least a portion of said second light fraction with a third hydrocarbon feed stream optionally comprising a part of said contaminated hydrocarbon mixture, said third feed stream having an end boiling point in the range of from 300‹ to 450‹ F., and reacting the combined stream with a gas containing hydrogen at a temperature of from 600‹ to 850‹ F. in a third reaction zone containing a hydrorefining catalyst, and (f) separating the resulting product stream into a normally gaseous phase and a hydrorefined third heavy fraction. The three feed streams may be derived from a single charge stock, a bottoms fraction forming the first feed, a kerosene fraction forming the second feed and a gasoline fraction forming the third feed. The charge stock may be a full boiling range coker distillate. Gas oils, deasphalted crude oils, fuel oils and catalytically and thermally cracked stocks may also be treated. The catalyst may be the same in all three reaction zones and may comprise molybdenum, nickel and cobalt; molybdenum and nickel; nickel and palladium; molybdenum and ruthenium; platinum; or palladium, supported in each case on a siliceous carrier material. Alternatively, the first reaction zone may contain a catalyst having a greater cracking activity and the third reaction zone a catalyst having a lesser cracking activity than that in the second reaction zone.

Title: Load-distance recording device for a vehicle
IPC: G07C5/06
Filed: 1973-04-27
Abstract: 1462365 Recording apparatus PEAK COMPONENTS Ltd 25 April 1974 [27 April 1973] 20029/73 Heading G1J The load carried and distance travelled by a vehicle are recorded on a time base by a recorder including an impulse generator 1 or 21 which produces an impulse each time a unit of distance is completed, a load cell 2 or 20 which produces a signal proportional to the vehicle instantaneous load, and a record medium moved at uniform speed past a single channel recording head 5 or 24 which, in response to said distance and load signals, records on the record medium the load, the completion by the vehicle of each unit of distance, and the time at which each distance unit is completed. The recording head may have a pen to mark a paper chart, or may be a magnetic head to store digital signals on a magnetic tape. In Fig. 1, each pulse produced by the generator 1 passes to an AND gate 4, and to the load cell 2 to trigger the release of an analogue load signal via an analogue-to-digital converter 3 and the gate 4 to the writing head 5 which marks on the chart a line transverse to the direction of travel of the chart and of a length representing the vehicle load, Fig. 2. As each line indicates the completion of a unit of distance, the vehicle speed can be calculated from the distances between successive lines. In Figs. 3, 4, the load cell 20 feeds a continuous analogue signal to the writing head 24 to produce a continuous trace of load against time. Undulations in the trace indicate that the vehicle is in motion. As each unit of distance is completed the generator 21 sends a pulse via a one-shot multivibrator 22 to cause the writing head to add a transverse line 27 to the trace.

Title: Improvements in or relating to bleaching cotton
IPC: D06L3/02
Filed: 1956-06-28
Abstract: Desized and wetted out grey woven cotton goods are treated in an aqueous bath containing, by weight, 1.25-2.0 per cent of hydrogen peroxide, 1.5-3.0 per cent of sodium silicate of Na2O/SiO2 ratio from 1/2 to 1/4 , 0.3-0.8 per cent of sodium hydroxide and a water-soluble salt of boron equivalent to 0.25-2.0 per cent of borax; they are then mangled or otherwise treated to give a 75-150 per cent by weight pick-up, heated to 200-216 DEG  F., maintained at 180-212 DEG  F. in a single continuous storage stage, for example, in a J box, for 0.75-1.5 hours, such period being limited to retain in the goods at least 15 per cent of the initial amount of the hydrogen peroxide, and thereafter washed.  The pretreatment may be effected with turkey red oil, a sulphonate or sulphate of a higher alcohol, a desizing enzyme or an aqueous solution of sulphuric or phosphoric acid. The hydrogen peroxide may be produced in situ from sodium peroxide, sodium perborate, or sodium percarbonate.  The boron compound may be borax or sodium perborate, provided that the required quantity of hydrogen peroxide is maintained.  In one example cotton flannel is treated at 140-160 DEG  F. with an aqueous solution containing a mixture of amylolytic and proteolytic enzymes, an alkyl aryl polyether sulphide and cetyl betaine and, after storing, is washed in hot water and treated with a solution containing 1.5 per cent of hydrogen peroxide, 2.5 per cent of sodium silicate (42 DEG  B<\>ae), 0.6 per cent of caustic soda, 0.5 per cent of borax and an alkoxylated aryl polyether alcohol, squeezed to 100 \sB 10 per cent mixture, steamed to 210-212 DEG  F., passed through a J box for 1.5 hours at 205-210 DEG  F., washed in water at 120 DEG  F. and dried on a clip tenter frame. Other examples are similar.

Title: Improvements in or relating to telecommunications systems
IPC: H04Q3/54
Filed: 1970-04-27
Abstract: 1,262,618. Automatic exchange systems. SIEMENS A.G. 27 April, 1970 [25 April, 1969], No. 20063/70. Heading H4K. In order to obtain information such as statements of account, rates of exchange or stock quotations, a subscriber by sending a special code or key signal is connected to a data set SM, SMVS, SMST, at the exchange which over an outgoing junction AVS connects an automatic announcement machine DVA, a subscriber compiling his request for information in the form of dialled or keyed data blocks with the end of each block marked by an earth or such like key signal, the data set converting the subscriber's signals to a form suited to the announcement machine and, in the event of a subscriber disconnecting without a block terminating key signal, the data set supplies such a signal and compiles a release data block for dispatch to the announcement machine. A subscriber TN1 with a line circuit TS1 is connected to a data set transmission bridge SMVS the outlet of which has a line circuit appearance TS3 so that a connection across network VN can extend the subscriber to outgoing junction AVS giving access to the announcement machine DVA. A tone from DVA exceeding three seconds duration is detected at ZA and indicates that instruction data will be received by the announcement machine. SMVS is accordingly switched to incorporate SM as a signal converter. If the subscriber dials impulses they are accumulated and stored in SP before conversion and sending. If the subscriber sends multi-frequency key signals a receiver/decoder TE supplies the converter SM. Circuit SMST is a data set control circuit. Class-of-service data established by exchange common control ZST can be stored in SP and made part of an initial data block sent to DVA for purposes of validation. If the announcement machine sends tone bursts of short duration, ZA responds and causes SMVS to switch SM to one-way speech amplification so that DVA can send the sought after information as synthesized speech. If the subscriber obtains a data set but fails to dial or key a request the transmission bridge SMVS provides a through speech channel or the data set may be released and a direct path provided across VN to the outgoing junction AVS.

Title: Electric resistance connections
IPC: G01C21/18
Filed: 1920-07-10
Abstract: 148,458. Krupp Akt.-Ges., F. Nov. 21, 1918, [Convention date]. Gyroscopic apparatus.-Four resistances A, B, C, D, Fig. 1, of polished wire are formed into circular arcs, the centres of which coincide with the axes of switches E, R, F, G having contacts c<1>, r<1>, f<1>, g<1> sliding on the resistance wires. The switch arms E, F are connected to a source of continuous current, and the switch arms G, R to a galvanometer H. One of the resistance wires A, C may be omitted and a fixed current diverging point substituted for the corresponding sliding contact. Fig. 2 shows the application of such an arrangement of resistances for stabilizing a gyroscopic arrangement consisting of a main gyroscope P and auxiliary gyroscopes Q, T mounted on a common base. The main gyroscope P carries switch arms p<2>, p<3> contacting with resistance wires k<1>, k<2> which are connected in series with resistance wires m<1>, n<1>, with which contact is made by switch arms q<2>, t<2> carried by the auxiliary gyroscopes Q, T. The switch arms p<2>, p<3> are connected to a source of current, the switch arms q<2>, t<2> being connected to a contact-making galvanometer H which energizes one of two electromagnets k<3>, k<4> according to the direction of its deflexion. The auxiliary gyroscopes Q, T also carry switch arms q<3>, t<3> contacting with resistances m<2>, n<2> connected in parallel to a source of current. The switch arms q<3>, t<3> are connected to a contactmaking galvanometer H<6> controlling two electromagnets n<3>, n<4>. Assuming that the gyroscopes P, Q, T have a tendency to rotate in the direction of the arrows X, Z, Y and that the switch arms q<2>, q<3> take up the position shown in dotted lines, the galvanometer H<6> is deflected owing to the disturbance of balance due to the motion of the arm q<3>. The magnet n<3> is thereby energized, reversing the motion of the gyroscope T until the arms t<2>, t<3> take up the positions shown in dotted lines, the gyroscopes Q, T having rotated through equal and opposite angles. The balance of the galvanometer H<6> is thereby restored, as also is that of the galvanometer H, which was disturbed by the motion of the arm q<2>. Motion of the main gyroscope P in the direction of the arrow X disturbs the balance of the galvanometer H, which thereupon energizes the electro-magnet k<4>. This exerts a torque on the gyroscope P in such a direction as to reverse its motion until balance is restored.
