Title: Linear x-ray spectrometers
IPC: G01N23/207
Filed: 1969-12-12
Abstract: 1,256,028. Feedback amplifiers; gain control. SIEMENS A.G. 12 Dec., 1969 [12 Dec., 1968], No. 60863/69. Headings H3Q and H3W. [Also in Division G1] In an X-ray spectrophotometer of the linear type, in which the direction, of the radiation from the specimen which is analysed, is maintained the same (during changes in the analyser crystal orientation which change the wavelength investigated) while displacing the analyser crystal along a line in the particular direction (the location of the detector being adjusted accordingly to maintain it on the Rowland circle -Fig. 1, not shown), the hyperbolic relationship between the amplitude of the detector output and the distance b between the specimen and the crystal is compensated for by the use of a potentiometer whose tap is coupled to the crystal movement and which modifies the characteristics of an amplifier in the detector circuit in accordance with this movement. The potentiometer may be a linear potentiometer whose slider is connected to the crystal mount, Fig. 2 (not shown), a circular or helical potentiometer whose tap is rotated by the screw drive for the crystal mount, Fig. 3 (not shown), or a contact-less magneto-resistive device. In one circuit arrangement, Fig. 4, the potentiometer P1 is connected across the output of a preamplifier VV which receives the counter tube Z1 output via a coupling capacitor C2. Base gain is provided by resistor R 0 . The effect of the potentiometer is to multiply the amplifier output by the above mentioned distance b and thus give a proportional relationship. Alternative locations for the potentiometer are before or within the amplifier VV or within the main amplifier HV, whose output connects via a pulse height discriminator a counter. Magneto-resistors may be used in the connection of the potentiometer to the amplifier circuit so as to reduce noise. In one arrangement, Fig. 5 and Fig. 6 (not shown), the magnet yoke carries two coils, one coupling a voltage derived from the potentiometer; to modify a magneto resistor in the feedback loop of the main amplifier, the other controlling the operating point of this resistor. The latter coil can also effectively introduce resistors to represent changing of the analyser crystal and of the order of diffraction, or this may be done by relays switching in appropriate resistors as in Fig. 5. In another arrangement, Figs. 7, 8 (not shown) the output of the preamplifier contains a voltage divider arrangement of two magneto-resistors one acted on by the sum and the other by the difference of the premagnetization field of a permanent magnet and the potentiometeractuated coil. Further coils provide for crystal and order of diffraction change.

Abstract: 1,274,159. Aerials. COMPAGNIE GENERALE D'AUTOMATISME. 23 Dec., 1970 [23 Dec., 1969; 23 Oct., 1970] No. 61047/70. Heading H4A. In.a steerable aerial a rigid support structure has an annular bearing surface which rests on a set of support rollers fixed to foundations, so that said structure may be rotated about an azimuth axis. As described, a main reflector 15, Fig. 2, of an aerial is rotatable about a horizontal elevation axis 18, and is carried by a metal girder construction 17 on top of a frustoconical concrete shell 51. Fastened to the lower face of the shell 51 is a circular flat rail 52, providing an annular support surface against which bear pairs of support rollers 30, mounted on foundation members 10. The position of each set of rollers 30 is adjustable by means of a jack 55. At least one roller 30, which may have a rubber tyre, will be motor driven, in order to steer the aerial in azimuth. Inside the shell 51 an inclined face defines a second bearing surface, having the form of a surface of revolution. Guide rollers fixed to the foundation members, and having axes parallel to the inclined face, bear against that face, and maintain the central axis of the first bearing surface in alignment with the azimuth axis of the aerial (Fig. 5, not shown). There is a cabin 19 in the shell 51 and another cabin 53 is provided below. A lift shaft 12 extends upwardly from the cabin 53, allowing access to the aerial proper. In another embodiment, the aerial is shown as of Cassegrain type, and a metal girder construction by which it is carried is extended to a cylindrical metal structure having a lower face defining a substantially horizontal annular bearing surface. Said surface rests on support rollers fixed to the top of a concrete cabin (Fig. 1, not shown). Retaining rollers and centering rollers are also provided, one of the latter being adapted to provide drive for azimuth steering (Figs. 3, 4, not shown). The main annular bearing surface may be of frusto-conical shape instead of flat, and rest upon tapered rollers whose axes meet at a point on the azimuth axis below said rollers, in order to provide a self-centring action.

Title: Pressure Regulator and Flow Control Valves
IPC: F15B13/02
Filed: 1979-12-04
Abstract: In a combination pressure regulating and flow control valve (10) having a first fluid passage (21-26, 28, 30, 31) interconnecting an upstream port (20) and a downstream port (27) an adjustable pressure regulating valve (34) is mounted in the first fluid passage to provide a reduced pressure at the downstream port. An adjustable flow control valve (66) is mounted in said first fluid passage for selective provision of either a meter in or meter out action on fluid flowing through said first fluid passage. In parallel with said flow control valve is a spring biased check valve (53) for selective provision of free flow in a direction opposite to the metering action of the flow control valve. A parallel second fluid passage (87, 88, 90-92) in the valve interconnects the upstream port with the downstream port. Mounted in the second fluid passage is an adjustable, spring loaded pre-exhaust valve (85) which is vented to the upstream port. When a meter out flow takes place from the downstream port through said first fluid passage to the upstream port the pre-exhaust valve is set to allow flow through the parallel second fluid passage until a pre-set pressure at the downstream port is reached and then it closes against flow. <IMAGE>

Title: Logic module or logic means for or in an integrated digital circuit
IPC: G06F11/22
Filed: 1980-01-22
Abstract: There is described a logic module, for an integrated digital circuit, for promoting testing of the latter, and which module comprises latch means having a plurality of basic cells comprising flip-flops FF, each flip-flop FF having an input associated with respective logic gates including an exclusive-OR gate. The said latch means has an input SIN, a multiplexer, parallel data inputs D0 to D3, signal control lines for control signals B0, B1, and a feed-back line leading via a further exclusive-OR gate to the multiplexer. When B0 = B1 = 1, as in the mode shown, the latch means functions as a latch (buffer); when B0 = B1 = 0, the latch means functions as a linear shift register; and when B0 = 1 and B1 = 0, the latch means functions as a back-coupled shift register with parallel data input at D2 and D3 and useable in testing operations. The arrangement enables internally-arising test data to be monitored in parallel. In a modification, there is omitted the line for control signal B0 and the multiplexer is also omitted, this modified embodiment being able to function as a latch (buffer) and as a back-coupled shift register with parallel data-input, but not as a linear shift register. <IMAGE>
