Title: Improvements in or relating to brakes
IPC: F16D65/22
Filed: 1962-10-23
Abstract: 1,001,279. Internal shoe drum brakes. FORD MOTOR CO. Ltd. Oct. 23, 1962 [Dec. 6, 1961], No. 40036/62. Headings F2E and F2F. In a servo-shoe type internal shoe drum brake, spaced adjacent ends 32, 33 of primary and secondary shoes 13, 14, carrying linings 15, 16, are spread apart to apply the brake by an hydraulic cylinder 22 containing pistons 29, 31, each provided with a stem 42, 43, respectively, on which a respective valve 40, 41 is slidable against the force of springs 46, 47 normally holding them against stop rings 48, 49, the cylinder being provided with large diameter bores 27, 28 for the pistons 29, 31 and a small diameter bore 34 containing a piston 35 trapped between the ends of the stems 42, 43, an inlet 36 for hydraulic fluid being connected to the chambers associated with pistons 29, 31 via passages 38, 39 which are arranged to be closable by the valves 40, 41. In the rest position shown, valves 40, 41 are maintained spaced from the passages 38, 39 and on initial brake application fluid flows freely to the chambers to act on both pistons 29, 31. As braking force on the primary shoe 13 increases the drag forces acting on the primary and secondary shoes, owing to rotation of drum 11 in the direction A, causes piston 31 to move inwardly to close the valve 41 on the openings 39, partially trapping fluid in the annular part of the chamber to act as an anchor for the shoe 14, but allowing fluid to pass between the valve 41 and the stem 43, on which it is a loose fit, to act on the piston 35 and so transfer part of the drag force back to the primary shoe 13. When the direction of rotation of the drum is reversed, the piston 29 is similarly moved to close the valve 40 and transfer a part of the drag force hydraulically to the shoe 14, which would then be the primary shoe.

Abstract: 1,263,515. Cathode-ray tube circuits. MARCONI CO. Ltd. 2 June, 1970 [11 Aug., 1969], No. 40075/69. Heading H4T. Axial alignment of the beam of a television pick-up tube (e.g. image orthicon, vidicon etc.) is achieved by modulating the beam focusing field at a frequency which is a predetermined fraction of the field frequency and automatically adjusting the currents in beam alignment coils in accordance with quantities proportional to the difference in successive fields of the time of occurrence during both the line and field scans of video signals corresponding to a predetermined transition e.g. black-to-white, on a test card scanned by the pick-up tube. Fig. 1 shows the circuitry (additional to the pick-up tube not shown) involved and Fig. 2 shows the (waveforms) pulse trains A to H occurring in Fig. 1. As described, field pulses A are divided in a ¸4 divider 1 to produce the pulse train B which is supplied to the focus electrode of the pick-up tube via terminal B and also supplied as an updown control to a reversible counter 7. The field pulses A are also utilized to set a gate control 5 in the start condition producing pulses E to open a gate 6 which passes line frequency pulses from terminal L to the counter 7 previously re-set to zero by pulses D from a change-over control 3. Counter 7 then counts the line pulses which occur until the pick-up tube produces video signals C (supplied via terminal C to a level detector 4) corresponding to a white square in the centre of a black test-card and the leading edge of such video signals produces a stop condition in gate control 5 which terminates pulse E to close gate 6. On the occurrence of the next but one field pulse A gate control 5 is again set in the start condition and gate 6 again supplies line pulses to the counter 7 which, because of the change over in waveform B, now counts in the reverse direction until counting is terminated by the stop condition of gate control 5 produced on the next occurrence of the video signals C. The sign of the count difference is then stored in store 8 in response to pulse G from change-over control 3 and the output of store 8 is then utilized to control current flow in beam alignment coils for the field scan direction via devices such as motor driven potentiometers or digital or capacitive storage devices. To control alignment in the line scan direction the changeover control 3, which is operated by the output of a ¸2 divider 2 supplied with waveform B, conditions a control stage 9 to supply 5 Mc/s. pulses from a free running oscillator 9 to the counter 7 under the control of line pulses from terminal L and the occurrence of the video signals C (in similar manner to the operation of gate control 5 and gate 6) the sign of the count difference being stored in store 11 and utilized to control current flow in the corresponding alignment coils. Specification 803,122 is referred to.

Title: Instruments and methods for measuring the carbon monoxide content of combustion engine exhaust gases
IPC: G01N27/16
Filed: 1966-09-08
Abstract: 1,105,046. Measuring carbon monoxide concentration electrically. WESTF€LISCHE BERGGEWERKSCHAFTSKASSE. Sept. 8, 1966 [Sept. 8, 1965 (2)], No.40195/66. Heading G1N. Carbon monoxide is detected in the presence of hydrogen and hydrocarbons, i.e. in exhaust gases from an I. C. engine, by mixing the exhaust with air in known proportions and catalyzing the exothermic oxidation of both the carbon monoxide and the hydrogen present but not the hydrocarbons, by passing the gases over two platinum resistors 19, 20, Fig. 4, the latter heated to a temperature at which it catalyzes the oxidation of both the carbon monoxide and hydrogen and the former heated to a lower temperature at which it catalyzes the oxidation of the hydrogen only. The two resistors are connected in one branch of a Wheatstone Bridge, Fig. 3 (not shown), which is balanced in the absence of carbon monoxide and hydrogen. In operation, therefore, the out-of-balance reading on the meter (5), gives an indication of the concentration of carbon monoxide present. The different temperatures of the resistors 19, 20 are obtained, using the same heating current, by using different wire strengths and/or coil distance and/or diameter. In the embodiment, exhaust gases are withdrawn from the exhaust by a probe (2, 12), Figs. 1, 2 (not shown), adjustably attached to a vertical rod (1, 11). The gases are cooled as they pass along the probe, the condensed water vapour collecting in a water separator (6). Solid impurities in the gases are removed by a ceramic filter (7) and lead tetraethylene by a further filter (8) of e.g. active carbon. The gases then pass into the measuring device where they are mixed with air in the ratio 1:1 and finally flow over the two heated resistors.

Abstract: 414,356. Controlling combustion. THORNTON, A. A., 7, Essex Street, Strand, London.-(Bailey Meter Co. ; 1050, Ivanhoe Road, Cleveland, Ohio, U.S.A.) Jan. 31, 1933, No. 2977. [Class 51 (i).] In a steam-boiler or other furnace plant the fuel and air supply to the furnace are controlled primarily in accordance with an output variable such as steam pressure while secondary control of the fuel supply is effected by the relation between the fuel and air supply and also if desired the steam output from the boiler, furnace temperature or composition of the flue gases. As shown in Fig. 1, a steam flow meter 37, air flow meter 40, and fuel supply meter 34 are provided with indicating scales and are interconnected by a system of levers so as to indicate by means of a pointer 50 any departure from normal of the relation between the steam and air flow and the fuel supply. A Bourdon tube 14 operated by steam pressure serves as a primary control for the fuel and air supply and upon departure of steam pressure from the normal raises or lowers a presser bar 16 relatively to a reciprocating member 17, actuated by a cam 21 driven by an electric motor 29, and a double wedge shape member 18 carrying electric contacts 19, 20. Upon one or other of these contacts being closed current flows from the power line 25 through conductor 27 relay 22, or 23 conductor 31 or 32 to the motor 11, for actuating the flue damper 10, conductor 26 to line 24. Simultaneously energization of the relay 22 or 23 effects the operation of the pilot motor 30 through conductor 27 relay 22 or 23 and conductor 33 or 33a for varying the speed of the motor 5 for driving the stoker. In the event of the fuel and air supply and the steam flow not bearing the correct relation, a bar 43 closes one or other of two electric contacts thereon to operate the motor 30 through power line 25 conductor 34 and conductor 45 or 46. If either of the relays 22, 23 is energized the circuit through the conductor 44 is opened. The steam flow meter may be replaced by a meter for indicating the constituents of the flue gases or by a temperature indicating device sensitive to the temperature in the combustion chamber.
