IPC: G06F12/08

Abstract: A fast store-through cache process is disclosed in connection with an information processing network of multiple processors sharing a common main storage memory. Each processor has a cache memory including multiple cache lines, each line associated with an address in the main storage memory. Each of the cache memories has a cache directory for recording the main storage addresses that have been mapped into the cache memory, for identifying each of the cache lines as valid or invalid, and for holding status bits of data words stored in the cache memory. According to the process, a data word is stored in the cache memory during a first clock cycle, during which the associated cache directory is read to determine whether the corresponding main storage address is mapped into the cache memory. If so, and if no status bits in the data word require update, the store to the cache memory is complete. If a different main storage address is mapped into the cache memory, processor logic generates a processor interrupt signal during the second clock cycle, and the processor is interrupted during the third clock cycle while the cache directory is modified to purge the corresponding cache line. If the main storage address is in the cache memory but the data includes at least one status bit requiring update, the interrupt signal is again generated during the second clock cycle, with the cache directory modified to update status bits, again during the third clock cycle. The processing devices further incorporate special logic to force certain modifications to the cache directory in the event that two consecutive store or fetch operations correspond to the same location in main storage.

Abstract: The cylinder head (1) of a high-pressure cylinder (2) of a super pressure pump is pressed by means of at least one tensioning screw (8) onto the high-pressure cylinder (2), a taper (1.5) on the cylinder head (1) and a tapered sealing face (2.3) on the high-pressure cylinder (2) abutting one another. A cylindrical part (1.1) of the cylinder head (1) adjoining the taper (1.5) of the cylinder head (1) projects with sufficient play into the bore (2.4) of the cylinder (2) and accommodates the bores (1.3, 1.4) for the delivery line (4) and the intake line (3). The high working pressures in the pressure chamber (2.1) of the cylinder (2) are distributed to all surfaces of the cylindrical part of the cylinder head (1) extending into the pressure chamber (2.1), so that the surfaces of the outer shell, the internal surface of the bores (1.1) for the delivery line (4) and the internal surfaces of the intake non-return valve (5) have the same pressures. This makes it possible, using the same material, to run higher pressures and to design the wall thicknesses of the cylinder head (1) and the diameter of the cylindrical part (1.1) of the cylinder head (1) and/or the bore (2.4) of the cylinder (2) as small as possible and hence to keep the forces required for movement of the piston and the pumping losses within reasonable limits due to the compressibility of the water at the superpressures prevailing. <IMAGE>

Abstract: A technique for preventing a stalled linear motor device from damage including monitoring accelerometer servos which generate signals representative of the difference between a command acceleration signal controlling the linear motor and the actual acceleration experienced by the linear motor device which signal represents the acceleration error and the direction of the error. The different signal is compared against programmed limits to develop a break-loose signal when the programmed limit (positive or negative) is exceeded. The break-loose signal is monitored as to duration, which duration is preprogrammed according to the dynamics of the system specifications presently in use. In the event that the break-loose signal exceeds the preprogrammed time limit, a latch is set, generating an interrupt signal applied to the computer control which immediately removes all motive power from the system and tests the latch to determine the source of the error, the latch remaining in the set state awaiting the computer test and being reset only after recognition by the computer.

Abstract: In order to generate a sinusoidal AC mains voltage from a DC voltage, the DC voltage is converted into a square-wave voltage having voltage pulses whose lengths are controlled corresponding to the change in the sinusoidal AC mains voltage to be produced. The square-wave voltage is transmitted via a high-frequency transformer (TR). Subsequently, the transmitted voltage pulses are tapped off and filtered, in each case for a predetermined time duration. The secondary of the high-frequency transformer (TR) is in each case short-circuited during the pulse pauses which are determined by the sinusoidal control of the voltage pulse lengths, with simultaneous constancy of the pulse frequency. In these phases, energy is transmitted back via the high-frequency transformer (TR). As a result of this property, the circuit configuration can also be used as a charging circuit.

Abstract: In a beam scan velocity modulation (SVM) (15) system for a television receiver, a video signal (Y) is applied to a differentiator (31) followed by a limiting differential amplifier (32). A driver amplifier (33) coupled to the limiting amplifier drives an output stage (34) that supplies current to an SVM coil (26). Certain video signals with large high frequency content may tend to produce excessive dissipation in the devices of the output stage. To prevent this, a current source for the differential amplifier is controlled by a voltage obtained from a current sampling resistor (116), which voltage is a measure of the average current through the output stage. The magnitude of the current source is varied by a current limiting feedback circuit (35) to thereby vary the peak-to-peak signal output from the limiting amplifier to prevent overdissipation of the output devices. The driver amplifier performs a coring operation that is unaffected by the variable limiting.

Abstract: A position sensing module (10) comprises an inner shaft (12) coaxially located inside an outer shaft (20). The inner and outer shafts (12,20) are rotatably mounted on a support (24) and can rotate with respect to one another. A return mechanism (30) is engageable with the inner and outer shafts (12,20) enabling forward rotation of the inner shaft (12) to cause forward rotation of the outer shaft (20). The return mechanism (30) further enables extended forward rotation of the inner shaft (12) with respect to the outer shaft (20), and urges backward rotation of the inner shaft (12) to a rearmost position. The return mechanism (30) limits backward rotation of the inner and outer shafts (12,20) beyond a non-actuating position. A force spring (32) urges the outer shaft (20) to the non-actuating position. Sensors (34,36) produce electrical signals proportional to the angular position of the inner and outer shafts (12,20). A friction pad (83) can be disposed between the inner shaft (12) and support (24) to provide frictionalresistance to rotation of the inner shaft (12) with respect to the support (24).

Abstract: Liquid dispensing mechanisms are well-known for aspirating and dispensing liquids in clinical analyzers. However, some mechanisms are complex and involve several moving parts, all of which are subject to malfunction. Described herein is an improved liquid dispensing mechanism (10) which moves a dispensing tip (14) both vertically and rotationally between an aspirating station (A) and a dispensing station (B), preferably through an arc of a circle of rotation. The tip (14) is carried by a tip support (16) on a pump (12) which is slidably mounted on a carrier (22). The carrier (22) is mounted over a cam (50). A cam follower connected to the pump (12) extends through a slot (34) in the carrier (22) to the cam (50) inside. Stop means (110, 116) are provided for limiting the rotation of the carrier (22) between two circumferential positions to force the cam follower, and hence the pump (12) and the retained tip (14), to move relative to the still-rotating cam (50).
