Abstract: A multi-processor computer system is disclosed in which processing elements, memory elements and peripheral units can be physically added and removed from the system without disrupting its operation or necessitating any reprogramming of software running on the system. The processing units, memory units and peripheral units are all coupled to a common system bus by specialized interface units. The processing elements are organized into partially independent groups each of which has dedicated interface units, but the porcessing units share system resources including peripherals and the entire memory space. Within each processing element group at any one time, group supervisory tasks are performed by one of the processors, buy the superviosr function is passed among the processors in the group in a sequence to prevent a fault in one processor from disabling the entire group. Communication between groups is accomplished via the common memory areas.The transfer of the supervisory function from processor is performed by registering the supervisor's identity in a common area in one of the dedicated interface units which area is accessable to all procesors in the associated group and using program interrupts generated in the common interface unit to communicate between group processors.Access to the common system bus by the processing elements is controlled by the associated interface units by means of a combination serial/parallel arbitration scheme which increases arbitration speed without requiring a full complement of request/grant leads.

Abstract: The invention relates to an apparatus for external modulation of high-efficiency CO2 laser beams of defined wavelength, particularly for use in CO2 laser material working apparatuses. According to the invention two plates made of transparent material are arranged parallel to each other, the inner surfaces of the plates are reflective and the outer surfaces are non-reflective. The two plates are mounted so that one of the plates is rigidly connected to a massive oscillation-resistant base which comprises a strong permanent magnet, and that the other plate, together with a special hollow cylinder, is fastened on an elastic membrane, so that an oscillatable system is formed which, on the one hand, is driven by the electro-magnetic interaction between the permanent magnet and a coil and that the system, on the other hand, is damped by means of the frictional force of a suitable damping medium of high viscosity located in a gap between the stationary and the oscillating subsystems, so that a reproducable adjustment of the setting of the gap's width between the two plates is possible via the control current of the coil.

Abstract: A multibeam photometric measuring device includes a light assembly (12) comprising a single modulated light source along with a filter assembly (19) for passing only a desired band of wavelengths and an optical system for suitably focusing light from the light source. A fiber rotor arrangement (24) is provided for sequentially connecting the collimated light source to each of the plurality of fibers (34) disposed in a distributor (32). Light passing through the wells of the sample plate (40) is captured by discrete photodetector cells (44) disposed on a one-to-one correspondence opposite the wells of the plate. A reference fiber links (52) light from the light source to a separate photodetector (45) to provide a reference light signal with which the sensed photodetector signals are compared. The sensed signals are suitably multiplexed and processed by circuitry which allows control over the accuracy with which the signals are processed on the basis of their instantaneous strengths as well as reference readings taken during system initialization. Enhancement of colour distribution resulting from chromogenic reactions is provided by automatic agitation by mechanism (54) of the reacting agents within the sample wells before a reading is taken at each of the sampling intervals of a kinetic measurement sequence.

Title: Cartridge case ejector in automatic guns
Inventor: HALLQVIST STEN
IPC: F41A9/55
Filed: 1986-04-15
Granted: 1989-01-12
Abstract: The disclosure relates to an automatic gun which employs case ejectors (1, 1') for realizing extraction and ejection of the cartridge case from a spent round. The case ejector is also utilized for arresting the breech block during the recoil of the weapon and holding the breech block in an open position so that ramming home of a new round (3') may be executed. The ejector is exposed to the round in process of being rammed home, which round, during its thrust towards the homed position in the barrel, entrains the ejector so that the breech block (2) is released and may execute its closing movement int. al. with the assistance of spring means placed under tension during the opening movement of the breech block. The ejector and the breech block are designed with cooperating arrest and abutment surfaces which take up portions of the kinetic energy of the round which is in the process of being rammed. A separate buffer device (5) is also connected to the ejector, by means of which device the above-mentioned retardation/cushioning may be amplified. By such an arrangement, the feeding and ramming speed of the gun may be increased without the risk that each respective round jolt against the rear face of the barrel and derange the breech block in its closing cycle. Such a derangement would occasion cease-fire.

Abstract: An area-security system comprises a transmitting/receiving strip arranged along one side of an area to be secured and a reflection strip arranged along the other side. The transmitting/receiving strip is divided into transmitting regions and receiving regions, the transmitting regions consisting of a plurality of transmitting elements which are arranged alongside of each other and which are combined in at least two groups, and the receiving regions also consisting of a plurality of receiving elements which are arranged alongside of each other and are also combined in at least two groups. Modulated light from the transmitting elements strikes the receiving regions after being reflected by the reflection strip. A control circuit determines association of different groups of receiving elements with the individual groups of transmitting elements. A multi-channel evaluation, under the synchronizing control of a control circuit, evaluates the signals on the basis of various factors. The area-security system is particularly suitable for penetration-security or for entry-security application, and for the securing or control of machines.

Abstract: Novel methods and dental compositions for treating dental structures, such as teeth and subgingival structures, are disclosed. Uniquely, the dental compositions contain metal complexes which are characterized as having an unique aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian co-ordinate plot of the negative log of the metal ion concentration versus the negative log of the hydrogen ion concentration. This unique dissociation property enables the metal complexes to release therapeutic metal ions in the oral cavity for forming metal co-ordination complexes or salts within the dental structures. The formation of such complexes or salts within the dental structures is particularly effective and highly resistant to enzymatic degradation associated with microbial activity. Also, the metal ions are highly effective in inactivating the enzymes secreted by microbes in the oral cavity to further attenuate the disintegration process. The metal complexes of the dental compositions advantageously are highly soluble yet readily dissociable at pH ranges normally encountered in the human mouth. As the active ingredient, the dental compositions contain a monometal complex of a multivalent heavy metal ion and a polyfunctional organic ligand in a ratio of about 1:1. An example of a dental composition employed is disodium monocopper(II) citrate in an amount of about 4 mg./ml., as copper, in a liquid vehicle having a pH of about 7.

Abstract: The ski safety binding has front jaws (12,13) which are pivoted to opposite ends of the cross link (7) of a parallelogram linkage formed by two additional links (5,6) and the binding base plate. The jaws can move sideways under an excessive force which overcomes the force of the centralising spring (16). This centralising spring is a helical coil tension spring and is hooked to a pin (26) attached to the mid point of the cross link. The pin carries a two armed lever (27) with a control part (40,41) at each end. When the jaws have swung to one side to release the skier's foot, the control parts engage a projection (42) on the wall of the binding housing which enables the spring to restore the jaws to their initial position.
