Title: Planter population monitor
Inventor: STEFFEN DAVID EUGENE
IPC: G06F17/40
Filed: 1983-09-28
Abstract: A monitoring apparatus for a multi-row seed planting machine (10), includes a programmed microprocessor (34). A plurality of sensors (16, 18, 21) detect the machine functions e.g. seed sensing, distance sensing, planter lifting or lowering to be monitored, and the microprocessor receives and stores data corresponding to the monitored functions. The apparatus counts the number of seed signals received over a predetermined increment of travel and calculates the seed population planted in each row, and stores a predetermined plural number of the population calculations. The means storing the population calculations are reset to zero after sensing the lowering of the seed delivery apparatus at the beginning of the next pass over a field. The microprocessor also calculates the average values of the stored population data. The microprocessor also produces a failure signal if the stored seed population data fails to fall within preselected high and low limits. <IMAGE>

Title: Filtration system for diesel engine exhaust
Inventor: WADE WALLACE ROBERT
IPC: F01N13/02
Filed: 1984-02-02
Abstract: A filtration system to remove oxidizable particulates from the exhaust gas of a diesel engine has a filter element 15 to collect particulates from the exhaust gas and ignition means which is periodically activated to ignite a leading portion of the collected particulates, after which they continue to burn only by virtue of the oxygen content of the exhaust gas or other gas flow therethrough. The ignition means comprises (a) apparatus for adding excess hydrocarbon fuel either to (i) the intake manifold of the engine, (ii) the exhaust gas exiting from the engine, or (iii) a separate supply of compressed air, and (b) an electrically heated catalyst 17 upstream of the filter element 15 and able to ignite the hydrocarbon rich gas and produce an exhaust gas hot enough to ignite the particulates in the filter element. The main exhaust gas flow may continue through the catalyst and filter element at all times (Figure 1), may flow always through the filter element but by-pass the catalyst except during ignition (Figure 3), or may always by-pass the catalyst and also bypass the filter element during burning (Figure 4) in which case combustion is maintained by an auxiliary supply of air. <IMAGE>

Title: Sealing anodised aluminium
Inventor: RENTON STANLEY
IPC: C25D11/24
Filed: 1984-04-06
Abstract: Processes for sealing anodised aluminium carried out in a bath having a pH of at least 7 and in the presence of a smut-inhibiting additive have been discovered to give rapid, efficient sealing without the formation of bloom. Examples of smut-inhibiting additives are dextrins, phosphonates, carboxylic acids, and the reaction products of an aldehyde or dimethylol urea with sulphonates aromatic compounds. The reduction in time required for sealing reduces energy consumption in the anodising operation.

Title: Vibration compensated cathode ray tube display device
Inventor: HILSUM CYRIL
IPC: H04N3/22
Filed: 1984-05-09
Abstract: The electron beam of the CRT is directed at intervals, onto a sensor which detects the position of the beam and generates an output signal which is processed in a circuit (5) to provide a correction signal for application to the deflection system (3) of the CRT to reduce the deviation of the beam from the position it would have in a vibration-free environment. The sensor may comprise a photocell (10), having 3 or 4 sectors, an internal patch of material emitting secondary electrons, or a photoconductive area over- or under-lying the phosphor screen. The sensor may be integral with the CRT to detect movement between the electron gun and screen, or may be fixed on the CRT mounting or even the observer. The circuit (5) generates a signal indicative of the deviation of the beam which signal is stored and integrated to generate the output signal. <IMAGE>

IPC: F02C9/28
Filed: 1986-06-18
Abstract: A fuel control 14 for a gas turbine engine receives an input signal NHDOT corresponding to a desired rate of change of engine speed. A speed governor circuit 10, 11 generates a first output signal corresponding to the difference between a speed demand signal and an actual speed signal NH.

Abstract: Moulds (12) with end lugs (14) for securing the moulds to parallel endless conveying chains (10) have the end lugs (14) disposed at and/or above the level of the open tops (16) of the moulds. As a result, each mould lies relatively low relative to the conveying chains (the open mould top is at or below the level of the chains) at a filling location whereby a pouring arrangement relatively adjacent to ground level can be employed without the need to provide a pit. Further, each mould has a lower lip (17) which overhangs a forward wall (18) of the next succeeding mould; the spacing between the adjacent moulds remains substantially uniform, even at the upper level sprockets, and is too narrow to allow a pig from a mould to enter therein to cause jamming. <IMAGE>
