Abstract: A FIFO shift register (100) includes a parallel data in-port (PIN) to each of its cells (101-132) and a means for managing input (153,154) to determine for each cell whether it is to receive data and, if so, whether through its conventional serial in-port (SIN) or through its parallel in-port (PIN). The input manager (153,154) comprises a bi-­directional shift register of input manager cells arranged in one-to-one correspondence with data cells. A one-bit validity indicator stored within a given input manager cell is logically combined with asserted PUSH and PULL signals to determine the source of data for the associated data cell and its immediate successor. 
     This arrangement not only provides greater speed by minimizing bubble-through time, but permits the FIFO shift register (100) to be clocked. This capacity for synchronous operation permits ready VLSI implementation with concomitant advantages in economy, reliability and speed.

Abstract: In an interface unit (FAU) for connecting a PCM transmission path (PCM-Ü) to an exchange of a TDM telecommunications system, the supervisory circuits (Ü1 to Ün) of the system, which monitor information transmission criteria, should be monitored in such a way that their actual function is interrupted for a short time only. To achieve this, they are supplied successively with simulated parameters corresponding to an error event, even if they transmit one group- individual alarm signal only. If an error signal is produced, the supply of simulated parameters is immediately interrupted. If no error signal of this type occurs, the simulated parameters are fed in at least once more. <IMAGE>

Abstract: A coupling for connecting hydraulic conduits includes a tube (12) formed with multiple depressions (30,32,34) that are angularly and axially mutually spaced on the surface of the tube (12), a spring latch (18) having a corresponding pattern of multiple protrusions (24,26,28) adapted to fit within the depression of the tube (12), a connector body (14) permanently mechanically connected to one of the hydraulic conduits defining a recess (42) into which is fitted an O-ring (16), and a bar (44) adapted to be locked on the spring latch (18). The O-ring (16) provides a hydraulic seal between the conduits. The latch (18) includes an inclined surface (36) with which the bar (44) makes contact and by means of which the latch (18) is deflected as the conduits are forced axially together. When the bar (44) clears the apex of the inclined surface (36), it becomes locked within a recess (38) on the upper surface of the latch (18) preventing axial disconnection of the conduits.

Abstract: In the liquefaction of a permanent gas comprising nitrogen the temperature of a permanent gas stream at a pressure in the range of 75 to 90 atmospheres is reduced to below its critical temperature by passage through heat exchangers 10, 12 and 14. Providing at least part of the necessary refrigeration, a single nitrogen working fluid cycle 36 is performed in which the nitrogen working fluid is compressed to a pressure in the range of 75 to 90 atmospheres, cooled to a temperature in the range of 170 to 200 K, work expanded in expansion turbine 38 to a temperature in the range of 107 to 120 K, and warmed by heat exchange countercurrently to the permanent gas stream, thereby providing refrigeration for the permanent gas stream.

IPC: G01R33/44
Filed: 1987-11-27
Abstract: A method of high-speed magnetic resonance imaging in which the object to be imaged is placed in a high static magnetic field. Nuclear spins are excited in an image area in a selected plane of the object by superimposing a slice-selection gradient (114) along an axis and applying a pulse of radio frequency magnetic field (116). Following an encoding pulse sequence (120a) and rephasing of the nuclear spins by the application of a 180° radio frequency pulse (117), mutually orthogonal phase-encoding (150) and readout gradients (140) are alternately applied in the image plane to effect a traversal through spatial frequency domain (k-space). In a preferred embodiment of the invention, the readout gradient is applied as a continuous sinusoidal wave. If phase errors vary slowly in time, only a partial k-space trajectory is required. In one variant of partial k-space imaging, the trajectory extends over the k-space origin, and the information acquired from the extension is used to compensate for any phase errors. If the same number of points are collected as in a full k-space acquisition, signal bandwidth is maintained, and spatial frequency response is increased. In a another variant, two or more partial k-space acquisitions are performed and then pieced together in a "mosaic" prior to Fourier transformation. In a further variant, partial k-space acquisitions in the direction of the readout gradient are combined with interleaved acquisitions in the direction of the phase-encoding gradient to avoid discontinuities. Chemical shift is eliminated either by the application of a suppression pulse of RF field or by tailoring the frequency spectrum of the rephasing pulse so as to preclude rephasing of one or other of the chemical moieties.

Abstract: A collimator for a shielded effective point source of penetrating radiation, e.g. a radiotherapy machine which includes, after a primary collimator 16, a succession of a multileaf collimator 17, and a first and a second pair of independently adjustable block diaphragm leaves 30, 31, and 35, 36 at right angles to each other. By using rectilinear displacement of the multileaf collimator leaves 18 and the block diaphragm leaves 30, 31, a compact arrangement can be provided which fits into a standard RT collimator head. By curving the inner edges of the leaves to be tangential to the boundary ray an optimally reduced penumbra can be achieved. The block diaphragms enable the radiation leakage found in prior multileaf collimators to be minimised for small and off centre irradiation patterns.

Abstract: A tubular blank is formed seamlessly and divided into individual annular parts which are then profiled by means of two tools (10, 12) having the form of solids of revolution. The working of the annular parts (14) is effected in such a way that the specific pressure on the outer side and on the inner side is the same. Profile forming is effected with the aid of two interacting tools (10, 12) having the form of solids of revolution, the mutual spacing of which can be altered. The inner tool (12) acts on the workpiece (14) with its convex outer side (13), while the concave inner side (11) of the outer tool (10) is used. In this way, it is ensured that the surface pressures during working are the same both on the inner side of the vehicle wheel rim and on the outer side of the wheel rim. The device is suitable for the production of vehicle wheel rims both from steel and from light metal, e.g. aluminium.
