Abstract: A data storage method is disclosed for storing user data and segmentation information (47) received from a host onto tape. In addition to writing data words and segmentation data relating to record marks (REC) and file marks (FM), the method provides for the writing of further segmentation information concerning 'save set' marks (SSM) that serve to group the data records into sets that are distinct from the collections of records delimited by file marks. In one embodiment, the data words are stored in fixed-size blocks (39) with segmentation data being recorded in an index (40) that terminates each block. Preferably, file marks (FM) and save set marks (SSM) can be independently written to indicate segmentation after the same record. Furthermore a count of save set marks can advantageously be used to facilitate searching of the tape.

Abstract: A pilot operated hydraulic control valve for use in conjunction with a solenoid modulator to provide brake pressure modulation on heavier vehicles, particularly in so-called automotive anti-lock systems. The pilot operated slave unit has an inlet valve operable by travel of one piston (17) and an exhaust valve operable by travel of another piston (16). One is a main piston (16) which travels in response to pilot signal pressure (22) and during part of its travel controls travel of the other piston (17), an auxillary piston, away from a stopped position towards which the auxillary piston is biased. Thus the valve has three distinct and stable positions (supply to delivery, delivery held and delivery to exhaust) determined by the pilot signal pressure (22) and the effort travel characteristic. It can therefore imitate as a slave unit, the pressure modulations of a three-state antilock solenoid valve (4) but with increased fluid flow.

Abstract: An optical component having a plurality of light-transmittable elements each having an electrooptic effect, and a plurality of electrically conductive films. The light-transmittable elements are superposed on each other in a direction perpendicular to a direction of incidence of a light beam upon the optical component such that the adjacent light-transmittable elements are bonded together at the electrically conductive films interposed therebetween. The component may be suitably used as an optical modulator or other optical device, by connecting the electrically conductive films to a power source, such that the adjacent light-transmittable elements are exposed to electric fields in opposite directions. In operation, a light beam is incident upon the optical component in a direction parallel to the planes of the conductive films. The incident light is modulated as the voltage applied is varied.

Abstract: A programmer/timer for an appliance of the type having a rotatable cam drum (12) advanced for sequential actuation and deactuation of a plurality of electrical switches (20). The drum is advanced or indexed intermittently by an oscillating advance pawl (26) engaging a ratchet wheel (25) and also continuously by a gear (44) driven by a common motor for oscillating the advance pawl. The ratchet wheel (25) has a hub (38) which is frictionally engaged (37) to drive the cam drum. The driven gear in turn is frictionally engaged (51) with the hub to also drive the ratchet wheel. When the advance pawl engages the ratchet wheel for intermittent drive, the driven gear slips on the ratchet hub. Upon user selection, a separate cam track (52) lifts the advance pawl to permit the driven gear to continuously drive the ratchet wheel.

Abstract: A vapor phase growth process is disclosed for the fabrication of III-­V devices which utilizes organo-Group V compounds as a source material. In particular, organoarsenic and/or organophosphorus compounds are used and provide epitaxial layers of morphology similar to those grown with conventional hydride sources. Preferred organo-Group V compounds are liquids at room temperature and are considerably less toxic than their hydride (gaseous) counterparts. The organo-Group V sources may be used not only as a source during epitaxial growth, but as a wafer ambient which is used to prevent surface decomposition both before and after epitaxial growth.

Abstract: The nodes in a computer network utilize an encrypted key as a key identifier in a data packets transferred between nodes which eliminates the need for a receiving node to perform a memory look up operation to ascertain the key used to encrypt the data. Each node is provided with a master key that is unique to each node. When two nodes want to establish communications they first negotiate a shared key. This shared key is then encrypted under each nodes' master key. The nodes then exchange their respective encrypted key. The encrypted key of the receiving node is placed in the data packet to be sent by the transmitting node. Upon receiving a data packet, the receiving node decrypts the encrypted key to determine the shared key. This shared key is then used to decrypt encrypted data in the data packet.

Abstract: A method of correcting for background changes in a plasma emission detector comprising a photodetector array is disclosed. In the photodetector array a plurality of sensors are used to detect the emission lines from a discrete number of selected elements including carbon. It is shown that, to the first order, there is a correlation between the response at detectors other than the carbon detector with the response at a carbon detector. The exact extent of this correlation is highly dependent on the amount of nitrogen present in the carrier gas used in the system. A calibration curve can be generated which allows compensation at a frequency of interest as a function of the magnitude of the carbon signal. This curve will depend on the level of nitrogen in the carrier gas and can be empirically determined each time a new bottle of gas is connected to the system. In a preferred embodiment, the calibration curve is not referred to until the carbon response reaches a preselected threshold value corresponding to the point on the calibration curve where there is a measurable spurious reading.
