Title: Treatment or prevention of serpula lacrymans infection
Inventor: PALFREYMAN JOHN W
IPC: A01N63/38
Filed: 1991-01-15
Abstract: Trichoderma and Hyalodendron species, in particular Trichoderma harzianum, Trichoderma aureoviride and Trichoderma pseudokongingii, are effective in the treatment or prevention of Serpula lacrymans infections. Serpula lacrymans causes dry-rot in wood and is difficult and expensive to eradicate from wood by conventional means which involve removal of infected wood followed by sterilisation with fungicide. Such conventional treatments may even promote regrowth of Serpula lacrymans. An effective substance obtainable from Trichoderma or Hyalodendron, or the intact organisms, may be applied to treat or prevent Serpula lacrymans infection.

Title: Sonar surveillance system for shallow water
Inventor: DIX JOHN FRANK
IPC: G01S15/04
Filed: 1991-02-08
Abstract: A surveillance sonar system for detection particularly of swimmers comprises a number of sonar emitters/receivers 23 operating at a frequency which is high enough such that the signals are low range, leading to a signal/reverberation ratio insensitive to array dimensions and a requirement for only low bandwidth. Such a system is produced by locating a series of sonar detectors, both active and passive, to produce overlapping beams giving an insonified barrier at the minimum response range around a sensitive target 21. A continuous region extending along the length of the barrier is formed within each point is covered by at least two emitters. Coherent processing of the received sonar signals is then used. The overlapping beams could be produced by bottom located sonars 23 with upwardly directed beams or by sonars 24 sited on platforms in mid-water depth with horizontal beams. The spatial diversity thus produced by overlapping beams reduces the possibility of false alarms. The barrier sonars are sequenced such that there is minimum mutual interference. The system also preferably includes the use of a second tier detector arrangement provided by a high resolution sonar located on a boat which is directed to the general area in which barrier penetration is detected. <IMAGE>

Title: Method and apparatus for preparing machine pattern data
Inventor: SHIGETA KATSUNORI
IPC: D05B19/08
Filed: 1991-02-27
Abstract: Data for controlling a pattern of movements in a sewing, welding, drawing or other machine is prepared in blocks of convenient size for the data memory 24 of the machine. Each block contains information indicating how it is connected to other blocks. The sequence of data blocks can be stored in a larger memory, eg on a floppy disk 18, to be read out successively and perform machining according to the entire pattern data. Movement data is stored in terms of incremental change in position rather than absolute position and further data such as stitch length, speed and thread cut commands, in the case of a sewing machine, are stored with the position data. <IMAGE>

Title: Superconducting pulsed magnet separator
Inventor: PURCELL JOHN R
IPC: B03C1/033
Filed: 1991-03-28
Abstract: A pulsed superconducting magnet system (20) for use in a magnetic separator includes a vacuum vessel (22) and a cryogenic containment vessel assembly (26), and a superconducting coil (28). The helium vessel (26) includes a relatively thin metallic inner tube (34) for holding liquid helium and the coil, and a relatively thick outer tube (36) with a relatively rigid insulative spacer (38) positioned between the inner and the outer tube so that the tubes are not in contact with each other. The outer tube is predominantly metallic and has at least one joint (39) formed of insulative material to prevent the outer tube from forming a low electrical resistance loop. The inner tube provides a vacuum seal and the outer tube provides structural support for the inner tube so that eddy current losses resulting from ramping of the current to the coil are reduced. The separation vessel 10 contains magnetic stainless steel wool. A method of fabricating the helium vessel is also disclosed. <IMAGE>

Title: Measurement of receiver sensitivity of a radio communication apparatus
Inventor: ISHII DAISUKE
IPC: H04B17/29
Filed: 1992-09-11
Abstract: A radio communication apparatus (21) is tested by radio and optical test signals (RTS and OTS) simultaneously transmitted by a test transmitter (22). Each test signal carries a test digital data signal. The apparatus has a radio digital data recovering section (23-25) for recovering the test digital data signal as a first digital data signal from the radio test signal. An optical digital data recovering section (39-42, 44-46) recovers the test digital data signal as a second digital data signal from the optical test signal. A comparing section (48-52) produces a bit coincidence signal whenever corresponding bits between the first and the second digital data signals coincides with each other. A counter (54) counts up a count to an increased count in response to the bit coincidence signal during a predetermined time interval. An indicator (30-32) indicates the increased count as sensitivity of the apparatus. In another embodiment the optical test signal compared is retransmitted from the receiver (21) in response to a received radio signal. <IMAGE>

Filed: 1993-03-23
Abstract: The alarm finder comprises a wireless transmitter and receiver (A) carried by person doing the finding and wireless transmitter and receiver (B) attached to the item to be found. Normally (B) would transmit a signal which is "seen" by (A). When the signal received by (A) indicates that (A) and (B) are more than a predetermined distance apart, device (A) indicates an alarm situation. At this time the person carrying (A) has the option of transmitting a signal to (8) which would cause an alarm to be indicated at (B). Example of use: The target application would include, although not exclusively, the scenario of mother and child, where the mother carries device (A) and the child has device (B) attached.

Title: Method and means for cleaning a printing screen
Inventor: MACFARLANE DAVID WILLIAM
IPC: B41F35/00
Filed: 1993-07-06
Abstract: Cleaning apparatus (10) comprises an enclosed washtank (12) and a screen loading Unit (13). A pump is arranged to deliver high pressure heated water to an internal screen cleaning nozzle arrangement (14) and a ring-shaped external screen cleaning nozzle arrangement (15) which nozzle arrangements (14, 15) are arranged in a gap (19) between a screen support skid (16) and an entry screen support skid (17). The nozzle arrangement (14) is arranged to direct a spray of water outwardly; the nozzle arrangement (15) is arranged to direct a spray of water inwardly. In use, a cylindrical printing screen to be cleaned is pushed into the apparatus whilst high pressure heated water is being delivered by the internal and external nozzle arrangements (14, 15). As each portion of the screen is disposed opposite the gap (19), between support skids (16 and 17), that portion of the screen is washed on its inside and outside by water directed from the nozzle arrangements (14 and 15) respectively. The screen is pushed into the washtank (12) until the whole length of the screen has passed opposite the gap (19). The cleaned screen is then removed. Water directed from the nozzle arrangements (14, 15) is arranged to contact opposite sides of the screen at superimposed positions so that substantially no resultant force is incident on the screen during cleaning. The use of high pressure, heated water may result in the cleaning of screens at relatively low flow rates of water.
