Title: Improvements in or relating to gas chromatography-mass spectrometry
Inventor: MCCORMICK ANDREW
IPC: H01J49/26
Filed: 1968-07-05
Abstract: 1,255,962. Mass spectrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 16 June, 1969 [5 July, 1968], No. 32335/68. Heading H1D. In a combined gas chromatography-mass spectrometry system in which the output from a gas chromatographic column 1, comprising samples mixed with a carrier gas, is fed to the ion source 3, a transverse magnetic field, e.g. from permanent magnet 9, is applied to the ion beam from the ion source 3 to deflect the relatively light carrier gas ions in the beam and prevent them from impinging on a total ion beam monitor electrode 14, whilst leaving the relatively heavy sample ions substantially undeflected. The beam monitor electrode 14 precedes a mass analyser 6 and the magnet 9 is disposed between ion source 3 and the monitor electrode 14. As shown, the magnet 9, disposed adjacent beam-aligning electrodes 17, 18, is located between ion source 3 and an electrostatic analyser 5 which further separates the carrier gas beam 10 and the sample ion beam 11. An apertured electrode 13 intercepts the carrier gas beam 10 but passes sample beam 11 which is partly intercepted by beam monitor electrode 14 which detects the presence of a peak in the sample ions and initiates magnetic scans in the sector 6 to determine the mass spectra of successive corresponding samples from column 1. In an alternative embodiment, Fig. 2 (not shown), at least one pair of beam-aligning electrodes is disposed parallel to the ion beam and the magnetic field is applied before these electrodes so that the carrier gas beam is deflected outside the plates and does not enter the electrostatic sector 5. The magnetic field may also be formed by an electromagnet, and the carrier gas may be helium or hydrogen. The ion source 3 uses a 50 ev. electron beam to ionize the sample and carrier.

Title: Improvements relating to separating bark or bast from its supporting structure
IPC: D01B1/22
Filed: 1929-10-25
Abstract: 342,672. Obtaining bast fibres from plant stems. DRON, D. W., Falls Foundry, Belfast, and DRON ENGINEERING CO., Ltd., 10, New Burlington Street, London. Oct. 25, 1929, No. 32511. [Class 120 (i).] Fibre is obtained from stems of plants having a fibrous bark or bast by separating the inner part of the stem prior to removal of the fibre from the covering, the separation being effected by splitting each stem into two halves or segments which are turned in opposite directions substantially through a right angle and passing them through rollers. Leaf stalks are trimmed from the stems A which are passed, small end first, between a fluted roller a and a presser arm b pivoted at b<1> and having a spring b<2>. The stems are split up the centre by a circular knife c and are forced over a ploughshaped guide d, which turns the two split surfaces of each stem downwards, and are then passed between waved, grooved, or fluted rollers, the first pair e, e<1> of a system of such being shown. As the stems leave the guide d they may pass between the first and second of three contacting rollers and then thereby be moved upwardly into a reversing shoot and through the second and third contacting rollers be fed to the conveyer or drum of a decorticating machine either directly, or through a system of crushing rollers. In the type of machine. having such reversing shoot and feeding to a " return feed " decorticating machine the stems are fed initially root end first.

Patent GB-326152-A (GB)
Abstract: 326,152. Hamilton, R. M., and R. M. H. Syndicate, Ltd. Dec. 4, 1928. Totalizators. - An apparatus for indicating numerical quantities to the public, particularly for showing the odds prevailing in connection with a totalizator, comprises displaceable main digit scales and a stationary panel of zeros together with a series of movable pointers. When a pointer has ranged over the main scales and another pointer comes into view, the main scales are shifted laterally to expose a column of zeros and thus to change the denominational value of the indications. The invention is shown in connection with the display of odds as calculated for example by the apparatus described in Specification 307,816. Two slats 11, 12 bearing numbers as seen in Fig. 1 are suspended from sliders 14, 15 mounted on a rod 16, and behind the slats is a panel 13 covered with zeros. An endless chain 18 supports equidistantly a number of pointers 17 and is moved as required for indicating the odds at the moment. The sliders are extended and recessed so as to be respectively shifted by means of toothed segments 25, 26 fixed on intergeared spindles 27, 28. Supposing the odds are increasing, the upper pointer 17 will move off the scale and in doing so will rock the spindle 28 counterclockwise by engagement of a stud 20 on the pointer with a star wheel 30 on the spindle. The spindle 27 will thus be turned clockwise and will consequently shift the slat 14 to the left to expose one column of zeros (See Fig. 5). The lower pointed will now operate over this new range of odds and if a further range is required the slat will again be moved to the left to show another column of noughts. In a similar manner if the odds are decreasing from the position in Fig. 1, the segment 26 engages both sliders 14, 15 and moves the slats to the left to show zeros to the right, as in Fig. 6.

Title: Fuel injection systems for internal combustion engines
IPC: F02M51/00
Filed: 1971-07-13
Abstract: 1335893 Electronic fuel injection Systems ROBERT BOSCH GmbH 13 July 1971 [14 July 1970] 32691/71 Heading G1N In an I. C. engine electronic fuel injection system of the type having a monostable multivibrator to provide injection valve opening pulses in synchronism with engine rotation a first electronic device is provided to operate, when the butterfly valve of the engine is closed, to prevent the opening pulses being effective when the engine speed exceeds an upper limit and to allow the pulses to be effective again when the engine speed falls to a lower limit above the idling speed, and a second electronic device is provided to operate, in any operating position of the butterfly valve, to prevent the opening pulses being effective when the maximum engine speed is exceeded, the pulses being restored below this speed. As shown, in normal operation, the multivibrator 16 provides pulses to block a transistor 48 which in turn causes energisation of the valve solenoids 13 via transistor 11. The output of the multi-vibrator 16 is also applied to two passive networks 30, 30', whose outputs are in turn applied to respective bistable circuits 45, 46 having a common transistor formed by transistor 48. When the butterfly valve is closed, a switch 39 in the network 30 is closed and if the engine speed exceeds the upper limit, the network 30 switches the bistable circuit 45 and prevents transistor 48 from becoming blocked to provide the opening pulses. A resistor 53 provides the hysteresis whereby the engine speed must fall to the lower limit before the opening pulses can be restored. Network 30' operates in a similar manner for maximum engine speed cut-off, switch 39 and resistor 53 being, however, omitted. In a modification, Fig. 2 (not shown), the two electronic inhibiting devices are applied to a two group injection system utilising a bistable circuit to trigger the monostable multivibrator 16 and AND gates to select the group of injectors for immediate energisation.  In further modifications, the lower limiting speed to which the network 30 is responsive may be engine temperature dependent by replacing the resistor 35 with a temperature dependent voltage divider. Further, to avoid the effect of intake manifold pressure on the mark-to -space ratio of the pulses which are applied to the network 30', the input of the network 30' can be connected to a constant mark-to-space ratio pulse generator, e.g. the bistable trigger in Fig. 2 (not shown), or a further multivibrator triggered by the multivibrator 16.
