Title: Liquid ballasting and de-ballasting systems for a vessel
Inventor: CAMPBELL GEORGE THOMAS RICHARD
IPC: B63B13/00
Filed: 1985-04-30
Abstract: A ballast pumping system for vessels which does not require the ballast tanks to have a separate stripping system. The system can be partially de-ballasted by gravity as well as by pumping. A common central duct 21 stretches along the bottom of the vessel and level with or substantially below the bottom of the ballast tanks, at least one valve is positioned between each tank and the central duct, the valve positioned to fill and substantially completely drain each tank. A pressure relief system is also part of the ballast system. This pressure relief system has a vent trunk 50 connected to the central duct and has an air outlet positioned at a regulation height above the free board deck, the air outlet preventing water from entering the trunk whilst permitting air to enter and exit thus preventing a build up of pressure or vacuum in the central duct. <IMAGE>

Title: Distance measuring receiver system and method
Inventor: SPENCE LEWIS C
IPC: G01S11/08
Filed: 1984-10-19
Abstract: A distance measuring receiver system and method (101) for determining the distance of a receiving station from a transmitting station, which provides the distance information by the reception and processing of a pair of signals (preferably continuous wave carrier) transmitted by the transmitting station. The present invention receives the pair of signals (upper signal (F1) and lower signal (F2)) using an antenna (102) connected to a front end subsystem (104) for amplifying and frequency translating to baseband the received pair of signals (F1, F2). The pairs of signals (F1, F2) at baseband are supplied to the upper channel (401) and to the lower channel (402) of a filter subsystem (106). The upper channel (401) exctracts the upper signal and the lower channel (402) extracts the lower signal. The filter subsystem (106) supplies the upper signal to the first channel (501) and the lower signal to the second channel (502) of a lane expansion subsystem (108), which produces a plurality of difference frequency signals (113, 115, 117, 119) (of preselected multiples) in accordance with the upper and lower signals. An oscillator subsystem (110) generates an oscillator signal (210) (of preselected phase and frequency) as a function of a clock signal (123) generated by a precise source (125) (such as an atomic clock). A reference subsystem (112) in accordance with the oscillator signal (121) supplies a plurality of reference signals (127, 129, 131, 133) (having frequencies equal to the frequencies corresponding to difference frequency signals). By comparing the phase of corresponding difference frequency and reference signals, phase comparator subsystem (114) produces a plurality of measurement lanes of different lengths, which allow the present invention to zero in on the position of the receiving station. Substantial elimination of phase error to each signal caused by signal processing is achieved by the present invention. An upper channel automatic gain stage in accordance with the level of the signal pair controls the Vcc voltage provided to the amplifying stages of the front end subsystem and to the active devices of the upper channel, while a lower channel AGC controls the Vcc voltage provided to the active devices of the lower channel. This results in the power output of the amplifying stages and the devices being maintained at a preselected value irrespective of the level of the signal pair. In addition, the varactor diodes cancel out minute capacitance changes exhibited by the crystal tuned circuits in the upper channel and in the lower channel due to the change in Vcc, the output signal power and the movement of the operating point of the active devices.

Abstract: A laser beam with a straight line cross-section is caused to rotate with its straight line section at a known non-zero angle to the horizontal. As it rotates it crosses at least three light detectors spaced in the vertical direction. The extent of rotation of the beam is indicated by pulse transmitted to the detector station.

Title: Inverter for induction cooker
Inventor: BULLOUGH ROBERT IAN
IPC: H05B6/06
Filed: 1986-11-25
Abstract: In an induction heating circuit for a cooking appliance, a pan heating coil (L2) is powered at values determined by the state of conduction of a gate turn-off thyristor (VT1). To reduce the amplitude of current flow through the thyristor at turn-on, a circuit responsive to the voltage across a capacitor (CR) that resonates the pan coil (L2) is employed. The circuit is coupled to the resonant circuit comprising pan coil (L2) and capacitor (CR) by a saturating transformer (T1) and senses the instant when the current flow reverses, which point indicates the capacitor voitage 15 reaching a minimum. This information is used to turn-on the thyristor (VT1). <IMAGE>

Title: Measuring the level of beverage in a keg
Inventor: WELLINGTON STEPHEN LESLIE RUSS
IPC: G01F23/14
Filed: 1987-07-21
Abstract: A standard beer keg (1) has a spear (6) with a top fitment (7) and a tube (8) which is open at the bottom. Valves in the top fitment can be opened by a coupler having a carbon dioxide inlet leading to the headspace (9) and a beer outlet leading from the tube (8). The invention provides apparatus for measuring the volume of beer in such a keg and includes a coupler (12) connected to flexible pipes (13 and 14). A branch (17) from one pipe (13) is connected to a carbon dioxide cylinder or a pump (not shown). In use the pressurized gas enters the tube (8) rather than the headspace (9) which is connected to the other pipe (14). The pipes are also connected to opposite sides of a pressure-measuring device such as a manometer (15). Gas is forced into the tube (8) until it is heard to bubble from the bottom. The depth of beer in the keg is then proportional to the pressure difference between the headspace and the interior of the tube and is measured by the pressure-measuring device. <IMAGE>
