Abstract: A redundant array storage system that can be configured as a RAID 1, 3, 4, or 5 system, or any combination of these configurations. The invention comprises a configuration data structure for addressing a redundant array storage system, and a method for configuring a redundant array storage system during an initialization process. The redundant array storage system comprises a set of physical storage units which are accessible in terms of blocks numbers. The physical storage units are each configured as one or more logical storage units. Each logical storage unit is addressed in terms of a channel number, storage unit number, starting block number, offset number, and number of blocks to be transferred. Once logical storage units are defined logical volumes are defined as one or more logical storage units, each logical volume having a depth characteristic. After the logical volumes are defined, redundancy groups are defined as one or more logical volumes. A redundancy level is specified for each redundancy group. The redundancy level may be none, one, or two. Logical volumes are addressed by a host CPU by volume number, initial block number, and number of blocks to be transferred. The host CPU also specifies a READ or WRITE operation. The specified volume number, initial block number, and number of blocks to be transferred are then translated into a corresponding channel number, storage unit number, starting block number, offset number, and number of blocks to be transferred. With the present invention, it is possible for a logical volume to span across physical storage units ("vertical partitioning"), comprise only a portion of each such physical storage unit ("horizontal partitioning"), and have definable depth and redundancy characteristics.

Abstract: A data structure and method for uniquely indentifying, and optimizing access to, object instances in an object oriented programming environment on a data processor containing a memory. Objects are categorized into one or more classes which define the method of the categorized objects, and messages are sent by the data processor to objects to perform actions. The data structure consists of a persistent portion (310) containing a unique object identifier and a non-persistent portion (320) containing the access address of an instance data frame in memory. The access address is set to the address of the data frame when the message is sent in order to optimize subsequent messages to the same object instance.

Abstract: A magnetic circuit of a C-shaped magnetic core (1) with an air gap (2) in which a magnetic field sensor (5) is arranged, is excited with the current to be measured by means of an electrical conductor (8). An output signal of the magnetic field sensor (5) is proportional to the current to be measured. Without any special measure, the magnetisation characteristic of the magnetic core (1) acts as error in the conversion of the current to be measured into a magnetic flux density in the air gap (2). The special feature of the measurement transducer is a large difference between an external limiting contour (6) and an internal limiting contour (7) of the magnetic core (1). If the circumference of the external contour (6) is at least three times the circumference of the internal contour (7), a smoothing effect is produced which compensates for the non-linear magnetisation curve. <IMAGE>

Abstract: A telephone dial-inbound data acquisition system with demand reading capability. The system has particular application for remotely reading utility meters. A remote data unit (RDU) dials up a host computer on a periodic basis. The RDU is assigned a callback start time by the host computer. The RDU calculates an actual callback time based on the callback start time and a randomly generated time delay. The RDU dials up the host computer via a modem when the local time, as shown by an on-board real-time clock at the RDU, equals the calculated actual callback time. Meter reading data is then transferred to the host computer. The RDU also contains circuitry for detecting a polling signal generated by the host computer. Upon detection of this polling signal, the RDU immediately dials back the host computer and transfers utility meter reading data to the host computer. The RDU will also immediately dial back the host computer if an alarm condition occurs, e.g. tampering or a low battery condition. The RDU contains circuitry for characterizing the on-hook and off-hook electrical characteristics of the telephone line to ensure that the RDU does not interfere with normal operation of a customer's telephone line.

Abstract: In executing indivisible operations to be executed without being interrupted, pseudo-store instructions (PST) which do not perform data writing are used to perform a check for the presence or absence in a memory (1) of pages (A0-A3) necessary for execution of the indivisible operations. In the event of absence of the necessary pages, the necessary pages (A0-A3) are pre-stored in the memory (1). This prevents the generation of page fault interruptions during the execution of an indivisible operation, thereby enabling the indivisible operation to be implemented on a software basis. A disable interrupt instruction is executed prior to the execution of the indivisible operation as required, and data indicating an address of the disable interrupt instruction is preserved in order to return to the disable interrupt instruction. In the case where an interruption, such as a page fault interruption, which cannot be disabled even in a interrupt disabled state is generated during data processing, processing is resumed from the disable interrupt instruction after the termination of processing for the interruption or an asynchronous interruption, with reference to the address.

Abstract: A process for reaction control in the preparation of polyisobutylene by polymerisation of isobutylene at temperatures from -130 DEG  to 0 DEG C in the presence of from 0.01 to 1.0% by weight of a Friedel-Crafts catalyst, from 0.0001 to 0.1% by weight of a molecular weight regulator and a low-boiling solvent which is inert under the reaction conditions, where the % by weight are each based on the isobutylene employed, in which the solvent evaporated during the polymerisation is drawn off continuously, liquefied and recycled in the liquid state into the polymerisation zone, characterised in that the molecular weight regulators used are vinyl ethers. The vinyl ether used in the process acts both as accelerator and retarder of the cationic polymerisation.

Abstract: A twin beam parallelogram-type lift axle suspension system includes a bi-directional airlift spring (79) having opposite end plates (81,83) at either end thereof located between two parallel control arms (65,57) wherein expansion of the air spring (79) pivots the upper and lower control arms (65,67) with respect to a frame bracket (61) thereby lifting an axle (75) and wheels (111) attached thereto from engagement with the road surface. The end plates (81,83) of the bi-directional air spring (79) move about equally in opposite directions and remain substantially parallel to one another throughout expansion and contraction of the air spring (79) so as to about equally distribute forces of expansion of the air spring (79) between the upper and lower control arms (65,67).
