Abstract: A programmable medical device, e.g. a cardiac pacemaker, utilizes digital circuitry 40 for controlling the provision of cardiac stimulating pulses and analog circuit 42 for providing clocks, an output circuit and heart activity sensing. Digital circuit 40 includes a memory in which may be programmed on a permanent or temporary basis from an external programmer control information relating to rate, pulse width, pulse amplitude, refractory period, sense amplifier sensitivity and the mode of operation desired, In addition the output can be inhibited or a threshold margin test can be performed in which a reduced energy output pulse is provided to check if heart capture is lost. The pacemaker can operate in a hysteresis mode and provides a high rate limit which can however be exceeded by programming. The pacemaker further includes means for signalling the acceptance of a programming signal and means to reset the program acceptance circuit if extraneous signals are detected as programming signals. The acceptance circuit checks for the receipt of the proper number of signals within a given time, for an access code and correct parity. Timing is by means of a crystal oscillator and a voltage controlled oscillator controls pulse width to obtain energy compensation with varying battery voltage.

Abstract: In a multiprocessor system (2), a controllable cache store (18) interface to a shared disk memory (24) employs a plurality of storage partitions whose access is interleaved in a time domain multiplexed manner on a common bus (16) with the shared disk to enable high speed sharing of the disk storage by all of the processors (4, 6, 8). The communication between each processor and its corresponding cache memory partition can be overlapped with each other and with accesses between the cache memory (18) and the commonly shared disk memory (24). The addressable cache memory feature overcomes the latency delay which inherently occurs in seeking the beginning of a region to be accessed on the disk drive mass storage (24).

Abstract: This invention provides a process which involves visbreaking of a heavy hydrocarbon oil in the presence of a suspension of coal particles of 20-2000 micron size. The presence of the fine coal solids permits severe visbreaking conditions which increases the yield of fuel range distillate products. Coke deposition occurs on the surfaces of the coal particles rather than on the surfaces of the heater chambers. The coal particle surfaces also serve to catalyze demetallation of the heavy oil feedstock, and to adsorb demetallation deposits.

Abstract: In order to be able to execute a plurality of switching or control functions at the same time which have a particular dependency on one another, switches with a combined rotary and tension mechanism are used. Difficulties arise in making such a switch in that the overall rotation range of 360 DEG  can be used, and a pulling or pushing operation is possible in all angular positions. A switch constructed according to the invention solves this problem with the aid of two camshafts (7, 8). For this purpose, the one camshaft (7) is coupled by a clearance fit, and the other (8) by a force fit, to a control shaft (9) of the switch, in a rotationally fixed manner. In this arrangement, the other camshaft (8) is provided with axial, adjacently running grooves (20), which interact with a catch element (23), and a catch depression (21) inside at least one of the grooves (20), which is effective when the switch is in its zero position. <IMAGE>

Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

Abstract: A method is disclosed for insuring that two semiconductor chips which have a 1-bit defect at the same on-chip address are not paired at any memory address by a fault alignment exclusion mechanism (FAEM) which functions to position chips having such defects at different memory addresses. The FAEM employs an error map to determine which chips must be realigned in their respective columns and an address permute vector functions to effectively change the physical address of the chip in the column to a logical address. The two permute vectors for the two columns contributing to any new uncorrectable error are "exclusive-ORed" and the result stored in a second map along with an identification of the chip columns. This map is termed the forbidden result table. Any time in the future that a new permute vector is proposed for assignment to any column of chips, the changed permute vector is exclusive-ORed with the permute vectors currently assigned to all other columns of the memory to see if any such combination produces a result forbidden by the forbidden result table. If no such forbidden result is found, the proposed permute vector can be assigned with the assurance that no pair of chips previously found to produce aligned faults will align now in any row of the memory. If any forbidden result is found, the proposed permute vector is discarded and a new one proposed.
