Title: Electrostatic Spraying
IPC: B05B5/04
Filed: 1981-07-24
Abstract: An electrostatic spraying nozzle, particularly for agricultural use, provides for a high rate of liquid delivery, whilst maintaining uniform charging of the atomised spray by means of a low-current supply. Atomisation is produced centrifugally from a conical rotor 32 and the liquid is charged by contact with an electrically isolated conductive coating 36 on the inner surface of the rotor. The coating is raised to the potential of a high-voltage needle electrode 48 by conduction through one or more air-gaps 50 between the needle point and the conductive surface. The conductive surface shields the electrode from any external surface at earth potential and thus ensures that only the required charging current is passed by the electrode. <IMAGE>

Title: Burner Control System
IPC: F23N5/20
Filed: 1981-08-11
Abstract: A burner control apparatus for use with a fuel installation that has an operating control to produce a request for burner operation, a flame sensor to produce a signal when flame is present in the monitored combustion chamber, and one or more devices for control of ignition and/or fuel flow. The burner control apparatus comprises lockout apparatus for de- energizing the control apparatus, a control device for actuating the ignition and/or fuel control devices, and a timing circuit that provides four successive and partially overlapping timing intervals of precise relation, including a purge timing interval, a pilot ignition interval, a pilot stabilisation interval and a main fuel ignition interval. The present invention further includes a burner control system which verifies the proper operation of certain sensors in a burner or furnace including particularly the air flow sensor. Additionally, the present system also prevents an attempt to ignite a burner if a condition is detected which indicates that the air flow sensor has been bypassed or wedged in the actuated position. Verification of the state of the airflow sensor is achieved by means of photocouplers.

Title: Digital code detector circuit
Inventor: KINGHORN JOHN RITCHIE
IPC: G06F7/02
Filed: 1982-10-22
Abstract: A digital code detector circuit for detecting digital code combinations having a specified number of bits of one binary value (e.g. 1's). The circuit comprises a coincidence gate arranged connected in a series- parallel configuration to provide a plurality of unique paths each of which corresponds to a particular code combination. Each path has at least one gate in common with at least one other path, and the gates are opened selectively in response to true and inverse data signals for a digital code to complete the relevant path. A preferred implementation of the coincidence gate arrangement is in the form of an integrated circuit array logic structure composed of n-channel IGFETS. As shown in Figure 9, a single composite structure can be used to classify digital code combinations in accordance with the number of 1-bits which they contain. The array is arranged in respect of each bit of an applied digital code to give a conduction path "vertically" for a 0-bit and to divert the conduction path "left" for a 1-bit. <IMAGE>

Title: Equipment for adjusting the position of an earth satellite having a magnetic moment generator
Inventor: BRUDERLE ERNST
IPC: G05D1/08
Filed: 1983-04-15
Abstract: The position of an earth satellite is controlled by a magnetic moment generator 5 interacting with the earth's magnetic field. The control signal for the magnetic moment generator is developed in a switch circuit 3 to which is fed a position error signal, and a polarity signal, emitted by a timer 2, containing information regarding the polarity of the earth's magnetic field. Both signals are combined into a polarity- dependent control signal for the magnetic moment generator 5. Connected between the switch circuit 3 and the magnetic moment generator 5 is a smoothing member 4, for example a delay member of first order. The abrupt changes, otherwise occurring upon a change of the polarity signal, of the magnetic moment supplied by the magnetic moment generators are thereby smoothed, so that the position of the satellite is adjusted without disturbances. <IMAGE>

Patent GB-2147614-A (GB)
Title: Heat transfer printing
Inventor: PORTER KENNETH
IPC: B41M5/035
Filed: 1983-10-01
Abstract: The invention provides a structureless medium which is 'transparent' to sublimable dye during the heat transfer printing process. The structureless, dye-transparent medium may be employed in two ways. It may be used to carry a design which is impermeable to sublimable dye so that a reserved print of the decorative design may be obtained on a suitable dye-receptive substrate of thermoplastic fabric or film by interposing the medium plus the impermeable decorative design between a sheet of heat transfer material and the substrate during heat transfer printing. Since the plastic film medium plus the impermeable decorative design (which are preferably adhesively combined) are not damaged during the heat transfer printing process, they may be re-used any number of times to impose the same design on further samples of the substrate using new transfer material at each printing. Alternatively, the structureless, dye-transparent medium may be interposed between a sheet of heat transfer material and a dye-receptive substrate when it is desired to avoid contamination of the substrate by materials other than the sublimable dye (such as adhesives, resins, binders, etc) which may be present on the sheet of transfer material.
