Title: Ion source for mass spectrometer
Inventor: MIZUNO TOKUO
IPC: H01J49/14
Filed: 1984-08-01
Abstract: An ion source of chemical ionization type for a mass spectrometer or the like has an ionization chamber which receives a reactant gas via openings together with a sample gas via opening 4. The reactant gas which is irradiated with an electron beam reacts with the sample gas to ionize the sample gas. The ionization chamber has a separate exhaust opening 28 so that the chamber may be evacuated independently of the electron beam irradiation and the take out of ions. This permits supply of a large quantity of reactant gas and facilitates controlling the pressure inside the ionization chamber. Combinations of ion source, liquid chromatograph and mass spectrometer are detailed (eg Fig. 5). The pressure may be automatically controlled (Fig. 6). Chemical and electron impact ionization are specified. Valve 9 conductance changes due to vibration or temperature variations are countered. <IMAGE>

Patent GB-2181008-A (GB)
Title: Infinite impulse response filters
Inventor: HEDLEY DAVID JOHN
IPC: H03H17/04
Filed: 1985-09-25
Abstract: An infinite impulse response (IIR) filter is operative to filter an input signal (x(n)) that comprises a sequence of digital words spaced in time by an interval T. The filter includes delay means (32, 34, 36) that delays the input signal by successive increments of time equal to T so as to cause the production of a series of relatively delayed signals (A,B,C,D) in which each signal is delayed by T with respect to the previous signal in the series. IIR processing units (38,40) receive respective groups (A to C and C to D) of the series of signals, the groups being offset with respect to one another by one word. The units (38, 40) are operative during each of plural successive clock periods equal to 2T to process respective sets of words obtained from the respective groups (A to C and C to D) of the senes of signals so as to produce two output words (F, H). A multiplexer (54) combines each two output words (F, H) produced during each clock period equal to 2T to constitute a filtered output signal (y(n)) comprising a sequence of output words spaced in time by the interval T.

Title: Lagging mat independent of construction spacing
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1988-07-12
Abstract: For the lining of headings or roadways in underground mining and tunnelling, lagging mats are provided, the longitudinal bars 2 of which are bent to a double hook 3 at only one end of the mat, whereas the opposite end 16 of the mat has straight longitudinal bars. At this opposite end, transverse bars 9 are provided on the longitudinal bars, which transverse bars are disposed on the upper (9, 9') or also on the lower (9'') face of the mat and, when adjacent lagging mats are laid one upon another, hook into the ends 10 of the eyes, so that a firm connection longitudinally of the heading is obtained. The eye ends themselves are connected, behind the double hooks formed, to the longitudinal bars 2 by at least two transverse bars 7,8 so that a stabilized double hook is obtained, the free end 10 of the eye or tip of the bar being bent up from the plane of the mat, so that the relevant transverse bar 9 of the adjacent mat can be effectively secured there. In this way a lagging mat that can be used independently of the construction support spacing is created, which can be used for several different construction spacings. It is also conceivable to construct such a lagging mat sufficiently long to cover several bays. <IMAGE>

Title: Determining the characteristics of conducting objects
Inventor: SORENSEN THOMAS PATRICK
IPC: G07D5/08
Filed: 1988-07-20
Abstract: An apparatus and method for determining the characteristics of conducting objects such as coins, metal foil, machine parts or wire based on the pulsed coil induction principle. Each coil 41, 42 is both pulsed and monitored for return voltage so that magnetic fields add, thus reducing the effect of movement of the object relative to the coils. A transverse coil 43 may be used for obtaining extra information about edge dimensions. The coils are of a rectangular shape and are all similar, thus providing for a uniform magnetic field over a sufficiently large area of an object path. <IMAGE>

Title: "Updating output parameters for controlling a process"
Inventor: AYLEN CARL ARTHUR WILLIAM
IPC: G05B13/02
Filed: 1988-09-23
Abstract: Values are assigned to a set of input parameters and these are supplied to a processor 1 which compares these values with corresponding values in an up-datable reference 4 representing a library of previous input parameter values and derived output parameter values. One or more of the stored parameter sets most resembling the input parameter values is selected and, from the or each selected set, the processor 1 derives values for the output parameters which are output at 5 to control a process, e.g. operation of a lathe, represented by the delay 6. The performance of the process is subsequently assessed at 7 and, on the basis of this, the values of the parameter sets in the reference 4 are undated. Subsequent input of parameter values then gives rise to derived output parameter values which benefit from the previous experience gained by the system. <IMAGE>

Title: Coin or token freed locks
Inventor: JACK GRAHAM M
IPC: G07F17/14
Filed: 1989-10-26
Abstract: A coin freed lock eg for a locker comprising a key operable locking mechanism coupled to a rotary member 22 which is movable by means of the key operable mechanism between an unlocked condition and a locking condition (Figure 5), the rotary member 22 affording a cam face 27 which is engageable by a feeler member 30, the member 30 having a contoured portion 33 which is engageable by a coin or taken to move the feeler member 30 such that it will not engage the cam face 27 (Figure 4). The feeler member may be a pivoted lever or a sliding element. A projection 31 on the member 30 engages a recess 25 on the rotary member to prevent rotation unless a coin has been inserted through inlet 14 to engage contoured portion 33 and pin 13 and move the member and its projection out of the recess. As rotary member rotates a cam face 27 on the rotary member displaces the feeler member to a further position in which coin is released from engagement with contoured portion 33 and becomes supported by a pin 24 (Figure 5). On unlocking, rotation of the rotary member moves pin 24 such that the coin is released and passes to outlet 15. Lever 30 is replaceable by a lever having a contoured portion 33 specific to a coin of a different size. <IMAGE>
