Title: Standing-wave linear accelerator
IPC: H05H9/04
Filed: 1974-11-28
Abstract: 1482433 Linear particle accelerators VARIAN ASSOCIATES Inc 28 Nov 1974 [30 Nov 1973] 51684/74 Heading HID A standing wave charged particle acceleration formed by a sequence of accelerating cavities 11 to 21 having aligned beam passage apertures 51 to 62, has its cavities divided into sets such that successive cavities of a set are non-adjacent, being separated by a cavity of a different set, and are coupled by coupling cavities 21 to 29 displaced from the beam path, one cavity of each set being driven by a source of electromagnetic wave energy; the arrangement permits control of the relative phase of the wave in adjacent acvities while dispensing with the use of drift tubes. In the accelerator shown, the accelerating cavities are divided into two sets, coupled by cavities 21, 23 ... 29 and 22, 24 ... 28 respectively, arranged in orthogonal planes about the beam axis 10. Magnetic coupling apertures 62, 62<SP>1</SP>... 71, 711 may be provided to compensate for the coupling which occurs between adjacent accelerating cavities via the beam passage apertures 51 ... 62, although for electrons the latter may be sufficiently small to obviate the need for compensation. Internally projecting posts in the coupling cavities are dimensioned to ensure that the coupling cavities and the accelerating cavities have substantially the same resonant frequency. The two sets of accelerating cavities may, as shown, be independently energized at respectively opposite ends of the structure, not necessarily at the same frequency, or only one set may be fed from an external source, the wave being thereafter fed to the other set with a suitable phase shift produced by a dielectric element (126, Fig. 5, not shown). The beam passage openings 51 to 62 have rounded edges to reduce the field gradient and risk of breakdown. The energy of the output beam may be varied by adjustment of the relative phase of the waves in the two sets of accelerating cavities.

Title: Differential digital converter
IPC: G01N21/00
Filed: 1969-10-28
Abstract: 1,242,939. Measuring digitally. BAXTER LABORATORIES Inc. 28 Oct., 1969 [31 Oct., 1968], No. 52649/69. Heading G4H. [Also in Division H3] To measure digitally the difference between two analogue signals occurring sequentially the first is stored on a capacitor 40 (Fig. 1) connected to the "B" input of a comparator B and the second is then fed to the "B" input of comparator A, a ramp signal being applied to the "A" input of both comparators. At equality of the ramp signal and the first signal, comparator B energizes a relay K4 to allow clock pulses to be counted in a counter 10 until, at equality of the ramp signal and second signal, comparator A energizes relay K2 to stop the count. After a delay determined by thermal relay K3 the count is printed. In spectrophotometry when the analogue signals represent optical transmissions of test samples the ramp is preferably derived from a capacitor C discharging exponentially through a resistor R to give a count representing the difference in their optical density. If it is required to measure the optical transmission difference a linear ramp may be used. The counting pulses are derived by rectifying the signal from the secondary winding of a mains transformer 24. Calibration.-Initially with a "blank" sample switch 30 is opened so that a 10 volt signal is applied to a comparator and the gain of amplifier 34 is adjusted until relay K2 is energized, the gain then being slightly reduced from this level. Two known test samples are then compared with switch 30 closed so that the capacitor discharges. The resistor R is adjusted until the count corresponds to the known value.

Title: Improvements in automatic pilot devices.
IPC: G01C21/18
Filed: 1966-11-24
Abstract: 1,170,087. Automatic attitude control. SOC. DE FABRICATION D'INSTRUMENTS DE MESURE. Nov.24, 1966 [Dec.6, 1965], No.52707/66. Heading G3R. In an automatic pilot a servomotor system following signals from a gyroscope includes a motor-driven tachometer generator the output of which provides negative feedback as well as a forwardly acting rate component. As described, a directional gyro and a gyro vertical are mounted on a platform which is automatically maintained horizontal by servomotors controlled by amplified electrical signals from pick-offs of the gyro vertical. The servomotors drive tachometer generators the outputs of which are fed back to stabilize the platform controls. A follow-up servomotor associated with a synchro system repeats the heading indication of the directional gyro and this system also has tachometer generator feedback. The signals from the three tachometer generators are each combined with attitude deviation signals to control servovalves e.g. to maintain a helicopter in a desired attitude about its roll, pitch and yaw axes.

Title: Ultrasonic scanning
IPC: G01S15/02
Filed: 1974-12-06
Abstract: 1490356 Ultrasonic scanning devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Dec 1974 [10 Dec 1973] 52863/74 Heading G1G [Also in Divisions H3-5] A device for scanning an ultrasonic beam 204 over a plane P comprises two part-paraboloidal reflectors 201, 202 each associated with at least one transmitter/receiver transducer array M11, M21 rotating about an axis a1, a2 which extends through the respective reflector focus and is perpendicular to plane P. The arrays rotate at the same speed in the same sense and remain mutually parallel. The described embodiment, for medical diagnostic use, has two back-to-back arrays mounted in a rotating drum (Tl or T2) associated with each reflector. The arrays and reflectors are situated in a plastic bag filled with a coupling liquid. Each of the n elements of each array acts as receiver and the central transducer of each array is used also as a pulse transmitter. Transmitter and receiver circuitry, Fig. 3 (not shown) enables the use of arrays M11, M21, M12, M22 in that sequence. Array M11 is active while beam 204 moves, parallel to axis 203, from boundary 207 of the scan to the mid-scan axis 203; then array M21 is activated to continue the scan from the mid-point to boundary 208. Thereafter, arrays M12 and M22 provide a similar scan from 207 to 208. Following a first transmission pulse, echoes from a discontinuity SS are received by one of the n transducers in an array, the particular one depending on the orientation of the discontinuity, and are gated to a shift register store. The register has m sub-registers, associated with respective successive depth intervals in the scanned object, and each sub-register has n storage cells. It is arranged that the echo causes a signal to be stored not only in the cell associated with the transducer actually receiving the echo, but also in cells associated with a few immediately adjacent transducers. Following the next transmission pulse, echoes are similarly gated to cells of a second, identical shift register store. Echoes arising from third, fourth and subsequent transmission pulses are similarly gated to the first, second, first etc register, respectively. By then comparing the sub-register contents, echoes coming form the same depth interval but arising from successive transmission pulses can be identified. This establishes that the discontinuity has a defined extent and discriminates against spurious signals. Echoes thus identified (and which have been delayed to permit the comparison) are gated to the brightness control of a CRT whose X-deflection represents the scan position of the ultrasonic beam and whose Y- deflection represents the depth of discontinuities such as SS.
