Title: To investigate the potential of using beetle odours to deter slugs in vining peas
Inventor: GANI NARGIS ABDUL
IPC: A01N63/14
Filed: 2005-01-06
Abstract: In the UK slugs can be a major problem in vining peas. Their climbing and feeding habit on pea plants can often result in large numbers being picked up by the viners, causing contamination and possible rejection of the crop, consequently leaving the growers to meet the loss and face the costs. A likely answer, using the current interest in natural enemies as sources of potential chemical repellents, is now being studied by a PhD student at Cardiff University and hopefully this could lead to a new slug deterrent. It has been known for quite some time that slugs are reluctant to enter areas recently colonised by ground beetles, but it is only from an extensive series of laboratory experiments that it has now become clear that slugs respond to chemical secretions from the beetles pygidial glands - situated at the tip of the abdomen (see description figure 1). Normally discharged from the glands in response to attack by beetle predators, these secretions contain a cocktail of noxious substances - usually a mixture of acids and alkanes although the balance may vary from species to species (see description). That this defense mechanism also works to the beetles disadvantage in alerting its own potential prey was shown recently only at cardiff university (see description, Figures 2-5) as a significant change in the behaviour of the slugs when exposed to beetle extracts. Video recordings used to carry out these tests revealed a direct and rapid reaction on the part of the slugs when coming into contact with beetle extracts showing that the results are very encouraging (see description, page 1). The test also revealed that these slugs do not die during the course of this experiment. This must show that when slugs are exposed to beetle extracts there will be no side effects. The important chemicals have since been obtained, from commercial sources and tested to show its effect on deterring slugs from feeding on to growing plants and its effect on deterring slugs from climbing on to growing plants, under semi-field conditions. The findings conclude that beetle odours have the potential to develop into a new slug deterrent. Chemical companies will also receive the new slug deterrent as a potential source to stop and prevent slugs from entering into other crops currently for use in the UK.

Abstract: A modified vacuum distillation and delayed coking process for making substantially free-flowing coke, preferably free-flowing shot coke. A vacuum resid feedstock is used which contains less than 10 wt.% material boiling between 900~F and 1040~F (482.22~C to 560~C) as determined by HTSD (High-temperature Simulated Distillation). The use of such a high boiling resid favors the formation of shot coke instead of sponge or transition coke. The distillate recycle reduces coker furnace fouling potential of the heavier feedstock.

Abstract: This specification discloses a VCSEL (Vertical-Cavity Surface-Emitting Laser) device with single-mode output and optionally single polarization output. This device is given by lateral mode confinement by the PBG (Photonic Band-Gap) effect by shallow etching in a partial VCSEL top mirror. The PBG area encircles a MS-region (Mode-Shaping region), which is characterized by large longitudinal mode losses. The MS-region encircles the LA-region (Light Aperture region), which is characterised by low longitudinal mode losses. The MS-region does not contribute to the lateral mode-confinement to the LA-aperture, and the lateral modes confined by the PBG area. The VCSEL is thus optimized for single fundamental mode operation.

Title: A method for applying spectrophotometric data to digital images for visual comparison
Inventor: ROSBOTTOM ARTHUR L
IPC: G01J3/46
Filed: 2007-07-19
Abstract: A method for extracting and colour correcting digital image information from prepress CIP3 or similar final imposed files. A primary ideal image is displayed in comparison with a secondary image which is iteratively updated using spectrophotometric data gathered by reading press sheets with a colour bar scanning device. This reduces the need for hard copy colour proofs press side while eliminating the need to interpret differences between conventional hard or soft proofs versus printed materials. A prepress image data file representing final approved colour content is digitally transferred to a press side computer.  Personnel manually select the appropriate file which is automatically adjusted to visually reflect the final anticipated printed colour and is displayed as the primary image on a monitor. The secondary image colour is controlled through application of CIELAB values from a colour bar scanning device. Both images are viewed simultaneously for visual comparison.
