Patent GB-2080687-A (GB)
Title: Controlled release of active compounds from a polymer-based dispenser
IPC: A01N25/10
Filed: 1981-07-21
Abstract: A composition and method for the controlled release of compounds eg larvicides, molluscicides, nematicides, trace nutrients or plant regulants or herbicides from a plastic dispenser, generally in association with a porosigen in contact with water, for example, an aquatic environment or soil moisture. The porosigen, depending upon the desired end use and release rate of a compound, can have a solubility of less than 0.001 grams per 100 grams of water, up to 100 grams per 100 grams of water. The combination of the plastic dispenser containing the porosigen and compound results in a slow release which can last for days, months, and even years, through dissolution of the porosigen and the formation of a porous network permitting water to contact the dispersed compound located in the interior portions of the dispenser.

Title: Gate arrangement
IPC: E06B11/02
Filed: 1981-10-08
Abstract: The gate arrangement preferably comprises a pair of gates 1, 2 which are mounted on tiltable posts 7, 8. The post, when tilted cause the gates to swing open about axes of pivoting X1, X2 to allow the vehicle to pass through the gateway.

Title: Protection for under-carriage of air liners
Inventor: LLOYD JOHN
IPC: B64D33/04
Filed: 1982-09-24
Abstract: It is intended that when the plane is about to touch down, gases are diverted from the engine through a purpose made manifold onto a set of jets which are pointing directly to the ground. The force from the jets will allow the plane to touch down quite gently on the ground and prevent any violent force on the wheels of the under-carriage, and even though the under-carriage may be stuck or damaged, these jets will still allow the plane to land quite safely without damage. <IMAGE>

Title: Fly-under noise measurement apparatus
Inventor: HOLBECHE THOMAS ANTHONY
IPC: G01H3/12
Filed: 1982-09-28
Abstract: In noise measurement apparatus for measuring noise above an aircraft by a fly-under measurement an acoustically rigid spherical diffraction body (30) acts substantially as a reflector over a frequency range of interest to prevent suspending aircraft noise reaching transducers (33, 34) situated at a small azimuth to the suspension axis and at a position of minimum noise. The invention overcomes the problem of corruption of fly-under noise measurements by suspensing aircraft noise. The invention may be used in a noise assessment method involving simultaneous fly-under and fly-over noise measurement. <IMAGE>

Title: Registering book cover subassembly at transverse cutter
Inventor: MIMS JOHN D
IPC: B42C7/00
Filed: 1983-02-17
Abstract: A web (10) carring spaced boards (22) forming a book cover sub-assembly is provided with indicia, eg slots (20), used to control a cutter during transverse severing of the web. The slots (20) are provided within the marginal regions of the book cover sub-assembly, they are spaced from the longitudinal web edges by more than the width of a margin and have a dimension in the direction of web travel less than two margins. The sub-assembly is formed by accurately glueing wood or carboard boards (22) to a travelling paper, cloth or plastics web using fluidic-or photosensor-controlled sheet and web conveyors for monitoring side notches (18) and centre slots (20) in the web and leading edges (26) of the boards. The central slots (20) are cut through the web simultaneously with the side notches (18). As the sub-assembly approaches a rotating transverse cutter, a photocell and web movement pulse generator are used to control the cutter drive to sever the subassembly (at 12) into separate book cover sections. This arrangement using central slots (20) avoids misalignments occurring with edge indicia, permits observation of the indicia when the longitudinal margins are folded over the boards and avoids machine readjustment when the sub-assembly width is varied. <IMAGE>

Abstract: A track set for connection to an axle assembly (12) of the traction wheels of a vehicle or a trailer consists of a track set frame (6), a drive wheel (4), two track wheels (8,19), a track mat (3) and a track mat tensioning mechanism (9). The track wheels (8,19) are located at the forward and rearward ends of the track set respectively. The drive wheel (4) is adapted to be connected to the traction axle (12) and is located between and above the track wheels (8,19). The tensioning mechanism (9) comprises two rollers (5,20), one located forward of and the other to the rear of the drive wheel (4). The rollers (5,20) are spring-loaded to urge the track mat (3) mainly downwards so that the contact angle between the track mat (3) and the drive wheel (4) is maximised. The interval between the teeth of the drive wheel (4) is substantially larger than the meshing element of the track mat (3) entering this interval, and the pitch of the track mat (3) is larger than the pitch of the drive wheel (4). The track set enables various kinds of standard type land vehicles, such as agricultural, forest and bog tractors and their trailers to be converted into track- borne vehicles, and operates reliably even in difficult conditions. <IMAGE>
