Title: Capacitive fluid quantity indicator
IPC: G01F23/26
Filed: 1979-09-05
Abstract: A fluid quantity indicator, such as for aviation fuel, of the type utilizing capacitive type sensing probes 112 in which a capacitance change occurs proportional to the amount of fluid in a tank or container due to the dielectric constant of the fluid being different from that of air, comprises micro- processor control means 154 for providing display and totalizing control in conjunction with automatic compensation for the zero fluid capacitance variation, in a tank and automatic adjustment of the fluid full scale reading for variation in fluid tank capacitance. The microprocessor controls two independent digital servo loops, one of which is nulled when the microprocessor output is equivalent to the fluid quantity for providing a container configuration independent real time digital display of fluid quantity within a given container, and the other of which is nulled when an in-phase signal of equivalent magnitude and opposite sense to cancel out the real component leakage present across the sensing probes is provided. In addition, the microprocessor may be coupled to another microprocessor which functions total the signals from a plurality of containers or tanks on board the aircraft to provide a total display of fluid on board. <IMAGE>

Title: Lamp drive circuits for cine film projectors or cameras
IPC: H05B41/288
Filed: 1979-09-05
Abstract: A circuit for driving a compact source metal halide discharge lamp (10) comprises a d.c. power supply (18 to 28) coupled to switching means (32 to 36) which supply square wave alternating current to the lamp at a frequency of about 100 to 250 Hz. The d.c. power supply includes an a.c stage (20 to 25) operating at a frequency of the order of 30 to 40 KHz. The a.c. stage determines the internal inductive impedance of the d.c. power supply. The d.c. power supply may comprise a forward converter, an R.F. filter (16) and rectifying and smoothing circuit (17). A striker circuit (31) is provided for starting the lamp (10). The switching means may comprise two transistors (32, 33) switched on and off alternately by a circuit (36). When the lamp drive circuit is used with a cine projector or camera, the switching circuit (36) may be synchronised with the pull-down motion of the film transport mechanism by a sensor (40) and control unit (39). <IMAGE>

The individual stands are driven from a common drive motor (2) via intermediate transmissions (5), distributor transmissions (7, 8) and main drive transmissions (12) so that no loop is formed in the work-material between stands or even between the component units (10). <IMAGE>
Patent GB-2052232-A (GB)
Title: Metering cup for seed, fertilizer and the like
IPC: A01C7/16
Filed: 1979-12-14
Abstract: The metering cup includes a disc assembly (12) at the base of a hopper (10) having a screen-type impeller (18) driven by a ground engaging wheel with the impeller formed from expanded metal or the like. An adjustable inlet (19, 21) communicates with the hopper (10), and the air conveyor conduit (11) of an air seeder, communicates with the impeller approximately 180 DEG  from the inlet. The adjustable inlet controls the amount of material passing from the hopper through the inlet and the speed of the ground engaging wheel controls the speed of rotation of the impeller and hence the flow of material to the air seeder conduit. The angular displacement of 180 DEG  between the inlet and the air seeder conduit, prevents a flow of material, particularly fine material directly to the air seeder regardless of the forward speed of the air seeder. <IMAGE>

Patent GB-2080530-A (GB)
Title: Method of and Apparatus for Ultrasonic Measurement of Rate of Flow
IPC: G01F1/66
Filed: 1980-07-18
Abstract: A method of ultrasonic measurement of rate of flow for instance of oil passing through a pipeline 6, utilizes simultaneous passage of two auto-circulation pulse trains of opposite directions through a single acoustic channel through the medium to be measured while eliminating instants at which the pulses of the trains coincide. The pulses of one pulse train are used (at 16 or 32) to phase-synchronize a self- excited oscillator (15 or 31) whose frequency is a whole number of times the repetition rate of that pulse train. The coincidence instants (checked at 38) are eliminated by interrupting (via gate 1 or 9) the same pulse train before a certain instant of coincidence and restoring it with the help of a pulse produced by the self-excited oscillator, said pulse being held out of coincidence with a pulse of the other pulse train. The rate of flow is determined at 56 as the difference between the repetition rates of the pulses of the trains by comparing the repetition rate of the pulses of the other train with the frequency of the self-oscillator. <IMAGE>

Title: Recovery of materials from low concentrations
IPC: C22B7/04
Filed: 1981-10-30
Abstract: A process for separating recoverable metals from a material in which the recoverable metals are in a low concentration includes repeated contacting of a molten slag containing the recoverable metal with molten collector metals.

Title: Visually examining a gem stone
IPC: G01N21/87
Filed: 1982-04-06
Abstract: In order to examine the shape of a gem stone by sensing its edge or profile with great accuracy whilst enabling the central parts of the gem stone to be in sufficiently good focus for them to be examined visually for flaws, viewing means are used which provide images of the edge and of the central parts which differ substantially in nature, the images being separated. For instance, the stone 1 can be examined using a large numerical aperture lens 4; a small mirror 8 is placed on the optical axis so that the outer part of the lens 4 is associated with a first TV viewer 3 whilst the central part of the lens 4 is associated with a second TV viewer 9; the outer part of the lens 4 gives good resolution, and the viewer 3 can be focussed accurately on the plane of the edge of the stone 1; the central part of the lens 4 gives poorer resolution but a greater depth of focus, and the TV viewer 9 can be focussed roughly on the front face of the stone 1. The two images can be recombined to give a sharp dark line as the edge profile and detail of the central parts within the edge profile. Alternatively a chromatically unmounted lens can be used with light of different wavelengths to shift the focal point of the lens. <IMAGE>

Title: Automatic safety gas heating device
Inventor: MING-FUANG HUANG
IPC: F23N5/24
Filed: 1982-05-24
Abstract: A valve rod 21 of a gas heating device actuates not only a microswitch 4, but also a disc valve 3. A pilot burner 14 and a main burner 18 are separately controlled by individual solenoid operated valve 6, 7 which is serially connected. The disc valve 3 is provided at the upstream of the pilot burner 14, and between two solenoid operated valves 6, 7 for safeguarding against the erroneous on-state of the microswitch 4. A sensor 16 will, according to the presence of the pilot flame 15, instruct an electric control board 11 to continue or discontinue the sparkling of an igniter 12, to open or closes the solenoid valve 6 for supplying gas to the main burner 18. Thus, the adversity of toxication caused by either the misfunction of microswitch 4 or failure of valve actuation is able to be prevented. <IMAGE>
