Filed: 1987-03-26
Abstract: A conveyor drive belt 20 is formed from a plurality of identical belt strips of which three such representative strips 30, 40, 50 are illustrated. Each belt strip 30, 40, 50 is provided with two lateral grooves, one 32, 42, 52 on the respective strips upper surface and a second 34, 44, 54 on the lower surface. The grooves are disposed equidistantly on opposing sides, of the strips 30, 40, 50 respective centre points such that when the strips 30, 40, 50 are arranged in a stair like configuration the lower groove 34 of the first belt 30 is aligned with the upper groove 42 of the second belt strip 40 and similarly for the lower groove 44 of the second belt strip 40 and the upper groove 52 of the third belt strip. The aligned grooves thus provide lateral locating holes for attachment of the drive belt 20 to a conveyor. Holes 36, 46, 56 provided through each belt strip 30, 40, 50 five holes per strip, are also brought into alignment to allow the strips to be secured by means of bolts or pins (not shown). <IMAGE>

Title: Confining combustion products in a building structure
Inventor: FORBES GEORGE ALFRED
IPC: A62C3/00
Filed: 1987-04-30
Abstract: Combustion products are detected by appropriate strategically positioned sensors (18) within a building structure. Fire retardant partitioning, preferably in the form of roller blinds (13), is released in response to such detection to enclose the particular part of the interior of the building structure where the conflagration occurs to inhibit the spread of combustion products throughout the building structure. Preferably vent means (17), associated with the locally confined area, are then opened to pass the combustion products to the ambient atmosphere, and then a dousing fluid is introduced into the locally confined area. <IMAGE>

Title: Process and apparatus for spraying plant protective solutions or dispersions
Inventor: SIMM WALTER
IPC: B05B5/025
Filed: 1988-02-29
Abstract: The spreading out of the spray mist when plant protective solutions or dispersions are discharged is limited by the production of an electric barrier field between the high voltage electrodes (5) and the ground in the spraying zone, the field strength being adjusted to such a height at the high voltage electrodes that gas ions are formed there by corona discharge, the said gas ions partly flowing down to the ground and partly charging up the sprayed or atomized droplets. The charged droplets are then forced on to the plants or the ground in the treatment zone by means of Coulomb forces in the barrier field. The apparatus for carrying out the process consists of a field sprayer with spray nozzles (7) in which at least two high voltage electrodes (5) in the form of vertically arranged metal rods or metal tubes are provided laterally to the spray nozzles (7). The lower edge (6) of the metal rods (5) is a sharp edge so that corona discharge takes place there. <IMAGE>

Title: Door closer
Inventor: HARRISON STEPHEN JAMES
IPC: E05F3/10
Filed: 1988-07-15
Abstract: A door closer comprises a housing (10) containing a piston (22) acted on by a compression spring (21) and coupled to a pivoted arm (17) through a toothed element (23) rigid with the arm. The piston contains a row of rollers (25) which mesh with the element (23) and the transmission ratio between the arm and the spring is made to vary during pivoting of the arm by varying the distance (X) of the rollers from the axis (14) of the element along the row so as to give an increased torque at the end of the closing motion. The pitch of the rollers (25) may also vary along the row. The door closer may also incorporate fluid damping. <IMAGE>

Patent GB-2209838-A (GB)
Title: An improved magnetic recording medium for displacement detectors
Inventor: IIJIMA KENZABUROU
IPC: G01P3/487
Filed: 1988-09-15
Abstract: A magnetic recording medium for a displacement transducer is provided with one circular track (T1) for magnetic graduations and another circular track (T2) for standard marks. The standard marks (211, 212, 213, 214) are accompanied by specified magnetic identification marks (222, 223, 224) so that discrimination between the standard marks can be carried out by reading them out together with the identification marks. The provision of the identification marks means that the ability to discriminate between the standard marks is thus not related to the number of standard marks recorded in the track (T2). The medium is advantageously used for displacement detectors such as magnetic rotary encoders and magnetic linear scales. The figs. show two alternative forms of the identification marks. <IMAGE>

Title: Checking the state of aging of a catalytic converter
Inventor: RAFF LOTHAR
IPC: G01M15/04
Filed: 1991-12-06
Abstract: The state of aging of a catalytic converter in a vehicle exhaust system is checked, using a lambda probe downstream from the converter, by determining whether a transient change, which exceeds a preset amplitude, of the probe output signals occurs on a transition between lean and rich fuel mixture taking place within a predetermined time span. An overshoot transient US during a lean to rich transition indicates a fairly new converter. while an undershoot (swingback) transient during a rich to lean transition is a sign of a strongly aged converter. The transients are pronounced when the transition between rich and lean lasts less than 10 seconds. A method of monitoring the sensor output and determining the presence and size of the transients is described. <IMAGE>
