Abstract: MULTIPORT CRYOPUMP     Abstract A cryopump installation in which a novel cryopump 20 maintains a work chamber 12 at continu-ous high vacuum while periodically evacuating a load lock 14 in order to allow transfer of material from the load lock 14 to the work chamber 12 without disruption of the work chamber environment.  The cryopump has pumping ports 46 positioned on the radiation shield 50 in order to pump plenum 72 to a high vacuum.  Load lock gases enter the cryopump through port 46 and are condensed and adsorbed by the radiation shield 50 and second stage cryopanel 54.

Abstract: ABSTRACT           A lumber positioner having one or more parallel straight decks, and one or more parallel angle decks disposed transversely of, and in alternating sequence with the straight decks to extend at an angle no greater than 90° thereto.  One or the other of the straight deck or angle deck, preferably the former, is raised and lowered so that a piece of lumber can be transferred bet-ween the decks and travel in a direction along either when sitting thereon.  Preferably, a plurality of straight decks are constructed alike with each having a plurality of sections.  Each straight deck section has a chain with a plurality of alienable ramps for carrying lumber, spaced thrilling from adjacent ramps a distance equal to a lug spacing times the number of sections pre-sent.  As a result, when ramps of sets of corresponding ramps are aligned, one set of ramps will pass below the upper surface of the straight deck chains, while another set appears above the other end thereof.

Abstract: ABSTRACT OF THE DISCLOSURE In a method and a system for terminating invert-er operation of a converting device connected to a DC power transmission system and having a bridge connec-tion of thyristor valves, absence of a current flowing through the converting device is detected to provide an absence detection signal indicative of such absence, and the absence detection signal is used as one condi-tion for effecting  termination of the inverter opera-tion.  According to the invention, the absence is found when all the valves in at least one of the lower potential side and the higher potential side are found concurrently non-conducting, and each valve is found non-conducting when a voltage is found present across each valve.

Abstract: Abstract Apparatus for measuring the water content of a material having a source of infra-red radiation for directing at the material.  There is a detector for such radiation and first and second filters for selecting radiation for detection at wavelength bands in which respectively the radiation is and is not affected by water content within a predetermined range.  The system produces a signal representing the water content by referencing the detected signal obtained with the first filter against the detected signal obtained with the second filter.  The first filter has a response over a waveband that lies outside the range 1.91 to 1.98µm, and the center wavelength of which lies in the range 1.76 to 1.87µm.  The second filter has a response over a waveband removed from the response waveband of said first filter and substantially unaffected by the water content detectable at the response waveband of said first filter.

Abstract: ABSTRACT:          "A positioning device having pre-stressed contactless bearings."           A Positioning device having a plate-shaped carrier (5) which is slidably supported on a table (1) and is displaceable in a horizontal plane and on which a pressure force and a tensile force, respectively, are exerted by means of at least two translatory drives (11, 13). The translatory drives (11, 13) are coupled to the carrier (5) by means of horizontallyoperating static thrust and tensile bear-ings, respectively (33 to 41, 49) which via a viscous medium transmit pressure and tensile forces, respectively between the carrier (5) and the translator drives (11, 13) in a contactless manner. The contact-less bearings (33 to 41, 49) are pre-stressed with a force which is larger than the maximum tensile force occurring between the drives (11, 13) and the carrier (5). Thus a substantially frictionless coupling is obtained between the drives (11, 13) and the carrier (5).          This coupling acts at the same time as a guide for the carrier (5).
