Granted: 1995-06-06
Abstract: A sonar buoy 40 has narrow-beam sonar heads 80, 82 driven by a stepper motor 84.  The heads produce sonar data for example accurately measuring the seabed.  The buoy is handled by a crane wire 41 held taut by a float above the buoy and attached to a clump weight 46 resting on the seabed (although shown in retracted condition).  A wire 50 runs from a winch 48 around pulleys 52 on the weight 46 and is connected to a lever 54 of a gimbal mechanism 56 which has two transducers 62, 70 giving measurements of the "X" position and the "Y" position of the buoy.  A footage mechanism 76 is driven by the wire 41 and has a transducer giving a measurement of the heave position.  A compass 88 and roll and pitch transducers at 86 give measurements of the heading position and the roll and pitch positions.  The sonar data is compensated for the position of the buoy using a computer.     (Fig 5)

Abstract: The genes (sod) encoding Bacillus stearothermophi-lus and Bacillus caldotenax Mn-superoxide dismutase have been cloned in Escherichia coli and their entire nucleotide sequences determined. With the exception of the post-translationally cleaved N-terminal methionine residue, the predicted amino acid sequence of the B. stearothermophi-lus enzyme (BSMnSOD) exhibits 100 % similarity to the previously determined amino acid sequence. The B, caldoe-nax enzyme (BCMnSOD) differs by two amino acids from BSMnSOD. Both recombinant MnSOD's were shown to be functionally active in E. coli, both in vitro and in vivo, and were expressed to 47 % of the cells soluble protein by coup-ling their transcription to the E. coli trp promoter. The pharmaceutical use of these bacterial superoxide dismu-tases is described.

IPC: H01J23/12
Filed: 1994-10-18
Granted: 2002-01-15
Abstract: An inductive output tetrode includes a cylindrical ceramic envelope 1 within which is located an electron gun including a cathode 2 and grid 3. A resonant input cavity surrounds the envelope 1 and is located adjacent the electron gun so as to provide a modulating electric field in the cathode-grid region during operation to produce density modulation of the electron beam. The cavity 7 is connected to two metal cylinders 10 and 14 arranged immediately adjacent to the outside of the envelope 1. Metallic portions 12 and 15 located within the envelope 1 are co-extensive with cylinders 10 and 14 with the material of the envelope 1 being located between them. These act as r.f. chokes to reduce high frequency losses from the cavity 7. Tuning of the resonant cavity may be achieved by adjusting a tuning member 8 which is at distance of quarter of a wavelength at the resonant frequency from the cathode-grid region.

Abstract: A distribution network (108) receives simplex communications or pages from any number of user interface nodes (UINs) (202) and distributes the pages to one or more paging outlets provided by page termination nodes (PTNs) (110) and delivery systems (102). The UINs (202) perform the bulk of the processing related to the distributed system of the present invention. Originator services (1000) are provided through UINs (202). Through originator services (1000) callers may place pages or inquire about previously placed pages. In placing pages, page originators can specify options (1102-1104) related to the delivery of pages. Subscriber updating services (1100) are also provided through UINs (202). The updating services (1100) allow a subscriber to alter (802-812) the services provided by the distribution network (108). For example, the subscriber may change delivery addresses (402) which identify the delivery systems (102) through which pages are to be delivered.      Security procedures are implemented to insure that only authorized persons can alter the specification of services provided by the distribution network (108).
