Abstract: A reversible turbine pump includes a pair of end walls and a side wall defining an annular pumping chamber (11). A turbine impeller (23) mounted for reversible rotation in the chamber (11) includes a rigid input shaft (56). One end of the shaft (56) extends through one end wall (35) and is sealed from the chamber (11). A spring (71) biases the other end of the shaft (56) toward the other end wall. Cooperating thrust bearing members, mounted to the other end of the shaft and the other end wall, provide a large planar area of low friction engagement therebetween. The pumping chamber (11) has a pair of inlets (15, 16), a pair of outlets (17, 18) and a dam (14). The first inlet (15) and second outlet (18) are on one side of the dam (14) while the second inlet (16) and first outlet (17) are on the other side of the dam (14) so that reverse rotation of the impeller (23) pumps fluid in opposite directions through a different set of inlet and outlet. Valves (43, 44) associated with the inlets and outlets permit fluid flow in the desired direction and prevent fluid flow in the opposite direction.

Abstract: A parallel processor structure for modelling and training artificial neuronal networks is connected to a host computer and constructed as two-dimensional matrix of simple identical processor elements. The processor elements are supplied with a command stream by a sequencer in accordance with the SIMD principle. The processor elements arranged on the diagonals of the matrix are allocated to the nodes of the neuronal network and intended for carrying out the neuronal functions. The non-diagonal processor elements handle the logic combinations between the nodes and are selected for the function of the variable synaptic weightings. The matrix firstly has a local neighbourhood networking to the four next neighbouring processors in each case. In addition, lines come from the neuronal processors, separated in x and y direction, which drive the non-diagonal synapse processors in parallel. In one direction, these lines are used for accelerating the distribution of the calculation results of the neuronal processors to the synapse processors. In the other direction, the lines are used for the accelerated distribution of correction data during the learning process. <IMAGE>

Abstract: In a chemical analyzing apparatus, sample containers (54) reagent containers (54) cleaning port (7), a waste port (6), reaction containers (58), and a measuring cuvette (4) are arranged along one circumference. The sample con­tainers and the reagent containers are placed in a common area (8). An operator inputs from a keyboard (14) information iden­tifying those positions in the common area (8) at which sam­ples and reagents are loaded, for filing the information into a microcomputer (3). The filed information is displayed on a screen (13). The maximum total number of containers capable of being set in the common area (8) is constant. But, the numbers of sample and reagent containers (54) can be changed through the keyboard (14) such that when the number of sample con­tainers is large, the number of containers allocated for the reagents is reduced, or vice versa. A pipetting nozzle (9) is turned along the circumference and can be moved vertically at required positions. Transfer operations for various liquids are all carried out by a single nozzle. The nozzle (9) is operated to impart a sample and a reagent to one reaction con­tainer (58). Then, the operation of sucking a mixed solution from the reaction container (58) into the nozzle (9) and re­turning the sucked solution to the reaction container (58) again is repeated for full mixing. The reaction solution is supplied to the cuvette (4) by the nozzle (9) and subjected to measurement of extinction, fluorescence or scattered light. The reaction solution after the measurement is discarded to the waste port (6) by the nozzle (9). The nozzle is positioned at the cleaning port (7) on demand, whee the nozzle is cleaned by discharging a cleaning liquid through itself.

Abstract: The subject invention (20) provides a hand or foot operated park brake actuator (30) connected to a drive reel (48) via a flexible motion transmitting core element (68). The drive reel (48) is connected to an isolator crank (56) via a lost motion connection (46). The isolator crank (56) is operatively connected to a control crank (76) which, in turn, directly actuates the park brake (26). The control crank (76) includes a lock sector (102) which coacts with a pawl (104) to selectively maintain the park brake (26) in a brake applied condition. When in the brake applied condition, the lost motion connection (46) allows the drive reel (48) to return to an unactuated position thereby eliminating all stresses from the actuator (30). The pawl (104) includes an elongated slot (108) and a trip spring (110) which coact to alternatively ratchet the pawl (104) against the lock sector (102) and then to disengage the pawl (104) from the lock sector (102) without requiring an independent release mechanism.

Abstract: A plate made of a magnetic material (3) is secured to an optical disk so that it closes a central hole (12) formed in a disk substrate. An optical disk chucking mechanism for chucking the optical disk to a disk table attracts the magnetic plate by the magnet to cause a platen to abut to the disk substrate and a tapered portion (7) to abut to the inner side of the central hole so that the optical disk is restricted in position and is held. The optical disk and optical disk chucking mechanism restrict the loading position of the optical disk on the disk table independently of the mounting position of the magnetic plate on the disk substrate.
