Title: Rotating co-ordinate transformation apparatus and methods
IPC: G06G7/63
Filed: 1971-11-08
Abstract: 1361037 Transforming co-ordinates SYSTEM DEVELOPMENT CORP 8 Nov 1971 [9 Nov 1970] 51741/71 Heading G4G Apparatus for transforming the co-ordinates of a vector quantity (e.g. the stator voltage of an A.C. machine) from a first reference frame (the stator) to a second reference frame (the rotor) which rotates relative to the first consists of a demodulator, e.g. PD1, to which are applied the signal to be transformed and the output of a phase or frequency modulated oscillator VCO. The centre frequency of the oscillator represents the speed of rotation of the second reference frame and the phase deviation of its output signal is made dependent upon the angle between the reference frames (rotor angle). In the complete arrangement shown the stator current, field current and speed deviation of a synchronous alternator are computed from signals representing stator voltage, field voltage and rotor torque. The oscillator VCO produces two sinusoidal outputs 90 degrees out of phase so as to resolve the input voltage signals along both the sine and cosine axes of the rotor and accordingly the co-ordinate transformers are arranged in pairs. The voltage V as  across a selected phase winding of the alternator is integrated at A2 to provide a signal proportional to stator flux linkage. This is the input to the first pair of demodulators PD1, PD2 to which are also applied the two outputs of oscillator VCO, thus providing flux linkage signals referred to the two rotor axes. To the output of PD1 is added, at A5, a field flux linkage signal (from Al, see below) and to the output of PD2 is added, at A7, an amortisseur flux linkage signal (from A3, see below). The resultant outputs of A5 and A7, which represent stator current resolved along the two rotor axes, are applied to multipliers M3, M4 together with the two outputs of the oscillator VCO to transform the co-ordinates back to the stator reference frame. These components are added at A9 to provide a signal proportional to stator current (-i as ). The speed deviation signal Vc, which also modulates the oscillator VCO, is derived by multiplying, at M1, M2 respectively, the output of A5, the output of PD2, and the output of A7 and PD 1 and applying these outputs together with a signal T is  proportional to rotor torque to an integrator A6. The field current is derived by an integrator Al and an amplifier A4, the output of the latter being applied as an input along with V fs  to the integrator Al and it is shown that with appropriate gains, G 1 , G 3 , G 4 , the output of amplifier A4 will represent the field current - i fs . A similar arrangement consisting of amplifier A8 and integrator A3 is used to derive a signal - i gs  representing the amortisseur current.

Abstract: 1491689 Ionization flow meter ENTREPRISE DE RECHERCHES ET D'ACTIVITES PETROLIERES ELF 4 Dec 1974 [11 Dec 1973]  52394/74 Heading G1N [Also in Division H1] An ionization flow detector comprises a corona effect ion source electrode E 1 , collecting electrodes E 2 , E 3  constituted by grids at right angles to the gas stream, and electronic means for producing a signal representing the difference between the collecting electrode currents (which signal is proportional to the gas flow velocity). Electrode E 1  may be a wire, a wire tensioned in a mounting by a spring 72, Fig. 9a, a pin whose extremity is located adjacent the axis of electrodes E 2 , E 3 , a flat disc, or a grid Figs. 6, 7 (not shown). Electrodes E 2 , E 3 , may take up all or part of the conduit 2 and may be oval, square or circular. In Fig. 8, electrodes E 2 , E 3  are connected to a differential amplifier 54. In Fig. 3 the electrode currents are amplified at A 1 , A 2  and their sum and difference respectively are determined at A and C. The difference is amplified at A 3 , the gain of A 3  being controlled by the sum signal to be inversely proportional thereto and the output of A 3  being proportional to the ratio of the gas flow velocity to the ion velocity. The source 31 of ionizing potential is controlled by the output of A to have a constant current. Alternatively, source 31 may have a constant voltage or a constant load line. To produce an absolute value of the gas flow velocity the gain of A3 is set initially at a value depending on the ion velocity. This is derived Fig. 4 (not shown) by applying a pulsed voltage to E 1  with zero gas flow and measuring the time interval before a current pulse appears at E 3 .

Abstract: 1282765 Gob delivery means OWENSILLINOIS Inc 31 Oct 1969 [1 Nov 1968] 53408/69 Heading C1M In an apparatus for supplying gobs 12 in a predetermined order to a plurality of sections of a glass forming machine, a device for deflecting a gob from its path so as to prevent it reaching a selected section comprises a deflector 16 situated below a gob feeder 10 and positionable to deflect selected gobs by means of an air operated piston motor 22, the motor being actuated by a valve 28 which is in turn operated by a timer 32 common to the plurality of sections and manually operated means individual to each section. The valve 28 is of the four way spool type and is operated by air from the timer supplied to both ends of the valve by pipes 31. The timer 32 comprises a rotor rotatable within a housing in synchronism with the feeder drive. The rotor has two annular channels 39 communicating with passageways 40, 41 whose other ends communicate with successive ones of pairs of pipes 42, 43 as the rotor rotates, there being one such pair to each section. Air is supplied to one or other of pipes 42, 43 depending on the position of the spring biased spool of a corresponding valve 47 which is supplied with air through manually operated valve 51. In use, if it is desired to take a section out of operation the corresponding valve 51 is operated so as to shift the spool of valve 47 to the left and thus supply air to pipe 43 as opposed to pipe 42. As the timer rotor rotates the passageway 40 will communicate with the pipe 42 just as the gob intended for that section is being formed. Air is thus supplied to the left hand one of pipes 31 and the deflector moved to deflect the relevant gob into a cullet shoot 14. As the rotor continues to rotate the passageways will communicate with a pair of pipes whose corresponding section is still in operation and thus air will be flowing in pipe 42, air thus being supplied to the right hand pipe 31 and the motor 22 operated to return the deflector to a vertical position. A worm gear 53, 54 for manually rotating the housing to synchronize the timer prior to operation is provided.

A channel intensifier device is provided with an electron-permeable conductive membrane obturating the entrance to each channel. Fig. 2 illustrates an image intensifier wherein an aluminium layer D 500-1000 .U. thick is disposed adjacent the input electrode E1 of the channel multiplier section; the layer is opaque to radiation from the fluorescent screen S so that there is no need of a metal backing layer on the screen and consequently the spacing d and the voltage B2 can be reduced to give better resolution. The screen S may be laid on a plain glass or fibre optic window W. The layer D may be insulated from electrode E1 (Fig. 3, not shown) or may itself form the electrode E1 where it touches the glass matrix (Fig. 4, not shown). A photo-cathode may be spaced from the channel multiplier and focused on it by a conical anode which inverts the image (Fig. 5, not shown); the anode may be connected to the input electrode E1 or may be at a different potential. Alternatively, for an X-ray image intensifier the photo-cathode may be only 5 mm. from the channel multiplier.
