Title: Fuel injection systems
IPC: F02M69/22
Filed: 1972-07-05
Abstract: 1395526 Spray carburetters ROBERT BOSCH GmbH 5 July 1972 [5 July 1971] 31345/72 Addition to 1283860 Headings G3R R4 R72Y and R37D A fuel injection system for mixture compressing I.C. engines having continuous injection into the intake manifold and separate ignition as claimed in claim 1 of (1283860), said system comprising an arbitrarily operable butterfly valve and a measuring element arranged one behind the other in the intake manifold, the measuring element being arranged to be displaced through a distance proportional to the quantity of air flowing through the intake manifold, against a return force which is normally constant, said measuring element being arranged to actuate a movable part of a fuel metering valve which is arranged in a fuel line for the purpose of metering a quantity of fuel proportional to the quantity of air flowing, and an electromagnet the magnetic field strength of which is variable in dependence upon engine characteristics being arranged to act particularly in the direction of, and to vary the return force and being characterized in that the return force is provided by hydraulic pressure which is determined by a pressure regulating valve, the control current of the electromagnet and thus the initial stress of a spring of the pressure regulating valve being variable in dependence upon the oxygen content in the exhaust gas of the internal-combustion engine for the purpose of limiting the maximum valves of the concentration of carbon monoxide, nitric oxide and hydrocarbons. The hydraulic force opposing the movement of the measuring element 2 is provided by causing the fuel supplied by a pump 16 to act on the end-face 12 of a spool-type valve which meters the flow of fuel to the injectors. The pressure in the chamber 33 can be varied by the degree of opening of a valve consisting of a diaphragm 24 and a valve-member 36. The diaphragm is normally pressed against the member 36 by a spring 43, the force of which is modified by an electromagnet consisting of an armature 47 and a coil 51. The current flowing in the coil is determined by an ion-conducting solid electrolyte oxygen probe in the exhaust gas stream, the output from the probe being applied to the base of an emitter-follower transistorized amplifier. In order to be able to provide to the engine a mixture having a fuel-air ratio appropriate to varying conditions of operation, the metering element 2 and the fuel metering valve 7 are arranged to supply fuel and air in the ratio 1À05#, where "#" indicates a stoichiometric fuel/air ratio. The return force on the valve 12 is then modified by the action of the oxygen-probe system to supply a stoichiometric mixture. The transistorized amplifier also includes a circuit controlled by a switch which is closed shortly before the throttle valve 6 reaches the open position, so that the fuel/air ratio is adjusted to 0À9# for full load working.

Title: Improvements relating to type-composing apparatus
IPC: B41B27/32
Filed: 1958-10-01
Abstract: 899,133. Justifying type, &c. INTERNATIONAL PHOTON CORPORATION. Oct. 1, 1958 [Oct. 1, 1957], No. 31412/58. Class 100(3) [Also in Group XX] Type-composing apparatus is provided with a tabulator including an accumulator for adding the values of character widths and interword spaces forming a line in a column, a counter connected to the accumulator and arranged to be advanced a step each time the sum of the widths and spaces in the accumulator reaches a multiple of a given total, and means to add additional space to the accumulator after completion of a column entry to advance the counter to a predetermined position corresponding to the width of the column. The tabulator circuit 26, Fig. 1, shown in detail in Fig. 2, is arranged so that when composing text in columns, the operator using a keyboard KB associated with a typewriter displaying the text as it is composed, can compose one line right across the page, the added space necessary to advance to position to begin the next column being added to the accumulator 22 and stored in an auxiliary register 19. The counter comprises a stepping switch CS, and selector plugs 34 are inserted into selected plug jacks 30 thereof corresponding to the widths of the several columns as indicated by a scale 36 representing multiples of 128 units. The operations which can be performed are "TAB LEFT", text flush with the left margin of each column; "TAB RIGHT", text flush with right margin of each column; "TAB CENTRE", text centred between the margins; "TAB LEADERS", text divided into two portions flush with left and right margins of each column and separated by leader characters, such as dots, or blank space. The output signals of the keyboard KB are applied, for character identification, by cable AC to the register REC, and for character width, by cable NC to the register REC, the auxiliary register 19 and the circuit 20 operating the accumulator 22, as described in Specification 857,791. The register 19 may be a paper tape punched by eight perforators. In each operation, the binary accumulator is preset with all switches in "1" position except BI 1024 and BI 2048. In the case of "TAB LEFT" and "TAB LEADERS", the first column text is typed and then the key "TAB" is depressed. For "TAB RIGHT", the key "TAB" is depressed first. For "TAB CENTRE", the key "TAB CENTRE" is depressed first, and the space divided between the two registers. For "TAB LEADERS", a key TLC is depressed if leader characters are required. When the "TAB" key is depressed, the switch CS is stepped each time the accumulator reaches a multiple of 128. When the switch CS reaches a jack connected to a plug 34, the register and accumulator entries for the first column are completed. The procedure is repeated for each column. Manual operation can be used by means of keys HCM, COM and ROM. Specifications 754,102 and 807,757 also are referred to.

Title: Improvements in or relating to receivers for frequency-shift telegraphy
IPC: H04L27/14
Filed: 1953-11-13
Abstract: 740,298. Code-telegraph receivers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 13, 1953 [Nov. 17, 1952], No. 31529/53. Class 40 (3). In a receiving arrangement for frequencyshift telegraph signals in which the signals demodulated at 3 are applied to parallel-connected impedance arms including respectively capacitors 18, 19 and rectifiers 20, 26 connected with opposite polarities, and an output resistor connected between the junctions of the capacitors and rectifiers has a central tapping point 23 connected to the input of a valve 9 connected to a valve 9 having in its anode circuit the wind. ing 10 of an output relay 11 with a biasing winding 12 connected between terminals 14, 15, the capacitors 18, 19 are shunted by rectifiers 29, 30 in series with batteries 27, 28 so that the capacitors 18, 19 cannot be charged with a predetermined polarity above a prescribed maximum value. In response to positive (mark) portions of the signal voltage curve a at the cathode output of the valve 24, the capacitor 18 is charged positively via rectifier 20 and the capacitor 19 is also charged indirectly by current flowing through resistor 23. The time constant of the direct charging of capacitor 18 or 19 is made small with respect to length of a signal element, whilst the charging of a capacitor in the circuit involving elements 18, 19, 23 is long with respect to the longest signal so that a voltage curve c is produced between the point 25 and tap 23 and the input to the valve 8 becomes the curve a less the curve c. The relay 11 is arranged to respond when the input voltage passes through the value represented by the line b, i.e. when the voltages of the curves a and c are equal, and as the level of the curve e varies with the D.C. component of the output voltage of the valve 24 the variation of this component is neutralized in the input to the valve 8. When, for example, a long marking signal 7 occurs, the capacitor 19 eventually is charged with the same polarity as the capacitor 18, and the curve c rises exponentially, as indicated at 26, to the peak value of the curve a. In this condition, the receiving arrangement is very sensitive to interference and to overcome this difficulty, the capacitors 18, 19 are shunted by detectors 29, 30 in series with biasing batteries 27, 28 so that the voltages to which the capacitor 18 or 19 is charged indirectly, i.e. through resistor 22, is limited, and the curve c is prevented from rising to the level of the output of the cathode follower, but is held to the value indicated by the line 31 so that the receiving arrangement is made relatively in. sensitive to interference. The biasing voltage is preferably equal to approximately three quarters of the peak voltage normally detected.
