Filed: 1970-08-20
Abstract: 1313335 Fuel injection systems ROBERT BOSCH GmbH 20 Aug 1970 [21 Aug 1969] 40187/70 Heading F1B A I. C. engine fuel injection system comprises an accumulator 25', Fig. 2 connected between a fuel quantity metering pump (11) Fig.1 (not shown) and an injection nozzle 40, a valve member 42 between the accumulator and the nozzle operated by a solenoid 44 which opens the valve member to begin injection and closes it after the end of fuel injection and before the beginning of the subsequent metering pump delivery. The governor controlled metering pump (11) supplies fuel via line 15, non-return valve 22 duct 24, accumulator 25' and line 36 to a passage controlled by the valve member 42. When the latter closes duct 36 the fuel pressure in chamber 25' raises the spring- loaded piston 27 and when the valve member 42 is moved to the open position by solenoid 44 the fuel passes via annular space 45 and ducts 37, 38 to act on needle 48 which is lifted to commence fuel injection. The solenoid is energized by signals from a transmitter (54), Fig. 1 (not shown) and control device (52) in dependence on engine speed and cam shaft angle. The end of injection is determined by the stressing of spring 47 and the fuel supply pressure. Fuel leakages pass via 60 and 30 to tank (13). Excess fuel pressure is relieved through duct 65. In a modification the control surface of valve 42 has a levelled portion.

Title: Circuit arrangement for increasing the signal-to-noise ratio in colour television signals
IPC: H04N9/64
Filed: 1964-10-05
Abstract: 1,080,643. Colour television; radio receiving systems. FERNSEH G.m.b.H. Oct. 5, 1964 [Oct. 5, 1963], No. 40468/64. Headings H4F and H4L. To increase the signal-to-noise ratio of a colour television signal comprising a videofrequency luminance signal accompanied by chrominance information transmitted as modulations of a carrier wave having a frequency within the video bandwidth of the luminance signal, each colour component signal of the chrominance information, e.g. red, green and blue, is separated into lower and higher frequency portions separated by a common limiting frequency 1 Mc/s. lower than the carrier wave frequency, and the symmetrical impulse signal resulting from differentiation during separation of each higher frequency portion is suppressed by a limiter in a balanced amplitude range not exceeding the amplitude of noise components present in the symmetrical signal, the lower-frequency signal portion and the output from the limiter being re-combined in an adder. The Figure shows an embodiment of the invention in which the characteristics of the low-pass filter 2, high-pass filter and limiter 4 are illustrated by schematic graphs, U A  in box 4 being the output voltage which is plotted against the input voltage.

Title: Photographic colour printing
Inventor: NEALE DENIS MANKTELOW
IPC: G03B27/73
Filed: 1962-10-25
Abstract: 994,165. Photo-electric control of photographic printers. ILFORD Ltd. Oct. 21, 1963 [Oct. 25, 1962], No. 40486/62. Heading G1A. [Also in Division G2] A method of photographic colour printing, which comprises allowing printing light to fall on a photo-cell, cyclically interposing in the path of said light a filter passing one spectral band but not another, adjusting the relative intensities of light in the two spectral bands until the alternating output of a logarithmic amplifier connected to the photocell attains a predetermined amplitude, and printing with light so adjusted. The red/green ratio of the printing light is measured by shining the light through a stationary yellow filter 2, Fig. 2, and rotating red filter sectors, 7, 8 on to a photomultiplier 1. The photomultiplier is connected in a known arrangement in which its anode current is maintained constant and the dynode voltage fed to the input of a logarithmic amplifier to produce an output voltage which is a logarithmic function of the incident light intensity. Provided the response to the cyclically interrupted light is at least ten times that to the steady light, the alternating component of the output voltage is proportional to the logarithm of the red/green ratio. The alternating voltage is amplified, rectified and fed to a cathode follower Fig. 4 (not shown). The voltage required from the cathode follower is set up on a further cathode follower using a test transparency and deviations from this value are indicated on a meter. The red/blue ratio may be similarly established by replacing the yellow filter by a magenta filter.

Title: Engine valve control
IPC: F01L9/20
Filed: 1974-12-06
Abstract: 1471537 Controlling valve timing in IC engines R E VENARD 6 Dec 1974 [6 Sept 1973] 42001/73 Heading FIB [Also in Division G3] The timing of electromagnetically-actuated inlet or exhaust valves of I.C. engine cylinders is controlled by a programme which is operated according to a signal representing the value of various engine operating parameters e.g. engine speed, engine load, manifold pressure, throttle opening, ignition setting, exhaust gas condition, engine efficiency and engine power. A disc 1 with 360 spaced features 2 is connected to an engine crankshaft to rotate at ¢ crank-shaft speed. A transducer 3 detects the passage of features 2 and supplies a signal via a pulse shaper 9 to a pair of counters 12, 13. A feature 7 is detected by a transducer 5 at position 1, corresponding to top dead centre of one engine cylinder, and triggers a multi-vibrator 15 to signal a 3 millisecond counting time at counter 12 thus to form a 4-bit word indicative of crank-shaft speed. A feature 8, 30 degrees before top dead centre, generates a signal from transducer 6 to update the outputs of counter 12 and to reset counter 12. The counter 13 forms a 9-bit word indicative of instantaneous crank-shaft position and is reset by the signal from the transducer 5, as are outputs 26, 27. These outputs 26, 27 are supplied with data from inputs, 18, 19, 20, 21 concerning the engine operating parameters previously mentioned, which data is processed to form two 3-bit words at outputs 26, 27. These 3-bit words, together with the 4-bit word representing crank-shaft speed are addressed to read-only memories, 28, 29 for respectively generating 9-bit words for triggering opening and closing an engine valve, which are addressed firstly to data selectors 32, 33. Data for starting, braking or cruising is stored at 34 and supplied as 9-bit words to the data selectors 32, 33 which select data depending upon commands 35, 36 either from data store 34 or from read-only memories 28, 29. The selected data passes via outputs 37, 38 to comparators 39, 40 where it is compared with the 9-bit word from counter 13 indicative of instantaneous crank-shaft position. When this 9-bit word is the same as the selected data, a command signal is given to lines 45 or 46 to open or close an engine valve. The valve opening circuit may also include a loop 49, 50, 51, 52, 53, 54 to control the speed at which an inlet valve opens.  Valve construction. A poppet valve 74 has a sleeve 72 at the end of its stem 73 into which sleeve protrude two armature ends 70, 71 of a pair of electromagnets 64, 65 having coils 62 to effect opening and coils 63 to effect closing of the valve 74.

[Also in Divisions E1, F2 and H2] The plough of a cable-laying vehicle is mounted on an hydraulically controlled boom at one side of the vehicle where it is easily seen and controlled by the driver. The plough blade 51 is fixed to the boom 20 by a holder 55, and carries a rear cable shoe 52 through which the cable is fed via a pulley 8 and a funnel 67. A vibrator 71 can be fitted to the top of the plough and would give the blade a vertical vibratory motion to decrease the tractive force required to pull it through the ground. The funnel 67 can be replaced by a hopper (75, Fig. 0, not shown) to lay granular material along with the cable. The plough boom is controlled by three hydraulic rams (24, Fig. 2, not shown) 30 and 40. Ram (24) rotates the boom 20 about its longitudinal axis; ram 30 raises and lowers the boom, and ram 40 swings the boom towards and away from the vehicle side. The plough unit can be attached to a bulldozer (Fig. 12, not shown) by means of a special bracket. In its optimum working position the plough works in front of one of the vehicle wheels which allows this wheel to act as the means of ground compaction.
