Patent EP-0182873-A1 (EP)
Inventor: MAUDSLEY ANDREW A
IPC: G01R33/565
Filed: 1985-05-21
Abstract: Des images de Fourier basées sur des échos NMR (résonance magnétique nucléaire) multiples peuvent être obtenues en utilisant le procédé et l'appareil ci-décrit. Une séquence d'impulsions et de gradients sont appliqués à l'objet à prendre en image (30). Les impulsions commencent avec une impulsion d'excitation (72) qui est suivie d'une série d'impulsions de refocalisation (76, 76'). De manière à compenser l'erreur de phase dans les impulsions de refocalisation, celles-ci sont appliquées le long des axes alternatifs X et Y dans le cadre rotatif de référence. Les échos (78, 78') sont ensuite additionnés de manière cohérente pour conserver les informations de phase (56, 56'). Des échos alternés peuvent être inversés (52) dans le temps et leur conjugué complexe peut être pris (54) pour permettre une addition cohérente (56). Alternativement, les échos pairs (54') peuvent être ajoutés séparément par rapport aux échos impairs (56') pour produire des ensembles de données séparés. La séquence de commutation d'impulsions de gradients (30) fournit des inversions de signes de sorte que toute composante de ligne de base est annulée par l'addition cohérente. Avant ou après une addition cohérente, les échos sont transformés, et après formation d'un ensemble de données combinées à partir d'une série de séquences d'échos (50), l'ensemble de données combinées est de nouveau transformé pour produire une image de l'objet (60).

Abstract: The apparatus for measuring characteristics of a device under test (DUT) comprises a first signal generator (30, 11), which may be a crystal oscillator, for generating an input signal having a period Tforthe DUT (12), and a second signal generator (30, 25) for generating a sampling signal having a period t = nT + T/m, where n and m are integers. The sampling signal controls a first (13) and a second (15) sampler for sampling the output signal from the DUT (12) and the input signal to the DUT (12), respectively. The sample amplitudes are converted to digital by A/D converters (14, 16) and evaluated by a microprocessor (17) to obtain the characteristics of the DUT (12). The second signal generator may include a fractional N oscillator (25) for high accuracy and resolution and may additionally include a phase-locked loop circuit (21, 22, 23) coupled to the fractional N oscillator (25) to reduce phase noise and jitter thereof (Figure 2).

Abstract: A tansmission has a torque converter (TC) with an impeller (i) primary and secondary turbines (T1, T2) and a stator (9). In a first planetary gear set (PL1) the carrier (Cl) is connected to the primary turbine (T1), the sun gear (S1) is connected to the secondary turbine (T2) and the ring gear (R1) is connected to a one-way clutch (OWC1). A second planetary gear set (PL2) has a second carrier (C2) connected to the output shaft and a second ring gear (R2) connected to the first carrier (C1). A brake (BR2) is connected to the one-way chtch (OWC1) and to the second sun gear (S2) for low forward operation. The one-way clutch (OWC1) locks up the second planetary gear set (PL2) in drive operation. The one-way clutch (OWC1) is centrifically disabled before and during drive operation. A second brake (BR1) brakes the primary turbine (T1), the first carrier (C1), and the second ring gear (R2) in reverse operation, causing the secondary turbine (T2) to drive the first sun gear (S1) and the first ring gear (R1) to drive the second sun gear (S2) through the one-way clutch (OWC1) to turn the output shaft slowly in reverse. A second one-way clutch (OWC2) connected to the stator (S) provides phase differentiation in low forward and drive operations.

Abstract: @ A cryptographic system is used for the secure transmission of digitized signals to a plurality of receivers. At the transmission end, a key consisting of two blocks (A,B), each including a plurality of key fragments, is generated. For each transmission session, different sets of key fragments may be periodically selected (13) from one of the key blocks and used to encrypt the signals (12). Data indicative of the set selection (19) is generated. The key is distributed to each receiver. The set selection data is transmitted to all receivers along with the encrypted signals and used to construct the key fragment set for decryption of the transmitted signals. During the transmission session, the other key block may be varied to form a replacement key which is distributed to each receiver. At the end of the session, the functions of the key blocks are interchanged in all receivers at one time by selecting a set in the varied key block for use in encryption and decryption.

Abstract: A test machine has two testing stations 1 and 2 each of which has a test location 3 and 4 respectively at which components 5, 6 (incorporating their associated leads) are placed for testing. Each station has an alternating square-wave oscillator 15, 16 respectively, of an individual predetermined frequency. 
     Considering station 1, the signal of X Herz from oscillator 15 is passed to terminal 7 and to a gate of f.e.t.17. The signal output from test location 3 via terminal 8 is passed to an input of f.e.t.17. Thus f.e.t. 17 is gated by one signal and driven by the other, the resultant output being passed to galvanometer 18. The condition and value of the r.m.s. current at galvanometer 18 identifies whether the element (s) connected between terminals 7 and 8 are correct.

Abstract: The invention provides a stenter pin having a pin body (12) made of pressed sheet metal. One end of the body is attached to a chain (18) that moves the pin between the hot air/steam nozzles of a textile-drying or textile-treating stenter. The other end of the clip body is provided with a stainless steel table (22) that co-operates with a knife-edge (21.3) of a clip gate to hold the edge of the textile while it is transported through the stenter. Alternatively (as shown), the edge of the textile (4) may be retained by the pins (7.51) of a pin bar (7.5) which is also mounted at the front of the clip body. The central region of the clip body has a V-shaped region (12.1) and a pair of rolling bearings (11.1) are mounted on the two arms of the V-shaped region. The two pairs of rolling bearings move in guide channel rails (24, 25) fixed inside the stenter to prevent the tilting of the stenter clip. 
     The clip is made of pressed metal and so is cheaper than known clips; by arranging the bearing (11.1) at 45° to the horizontal, the height of the clip can be very small allowing the nozzles of the stenter to be positioned closer to the textile and hence allowing more efficient treatment of the textile.

Abstract: Apparatus for eg igniting a boost motor of a spinning projectile comprises an inertia wheel (5) which remains stationary within the spinning projectile and a linearly movable member (10) initially decoupled from the inertia wheel but become engaged therewith when a predetermined linear acceleration state of the projectile is attained and which then initiates winding up of a flexible tape coupled to a switch mechanism. When the tape has been fully wound up, ie when the missile has spun through a preset number of turns, the switch mechanism is pulled to operate it via the tape. Thus, the switch mechanism is only operated when the predetermined linear acceleration condition and the preset number of rotations (which equates to a preset flight distance) have been attained.
