Title: Magnetic recording and/or reproducing apparatus
Inventor: HONG KWON-PYO
IPC: G11B15/467
Filed: 1990-09-13
Abstract: A magnetic recording/reproducing apparatus not requiring mechanical adjustment of the X-distance of an Audio/Control (A/C) head is disclosed. The apparatus comprises a reference pulse generating means 70, a delay control signal generating means 62, and first and second delaying means 66 and 68. The apparatus compares the reproduced control pulse with the generated reference pulse to shift the reproduced control pulse to accord with the reference pulse. Therefore, the apparatus compensates the deviation of X-distance by a circuit means, not by conventional mechanical adjustment. As a result, the adjustable supporting structure for the A/C head can be discarded to simplify the deck structure, and accordingly a compact and economical apparatus can be achieved. A simplified A/C head support structure is also disclosed. <IMAGE>

Title: Permanent sleeper earring
Inventor: REMINGTON ROBERT
IPC: A44C7/00
Filed: 1990-10-25
Abstract: The permanent sleeper is a small plastic device in two parts that when joined together through the earlobe make a perfect shield from any cheap or otherwise metal earrings. It will be made of see-through plastic and will be virtually invisible once in position. The device should be fitted tight enough as to make a water tight seal between itself and the surface of the lobe, however should water become trapped the two pans could with a small amount of effort be prised apart allowing cleaning etc. With the permanent sleeper in place the pierced hole through the lobe has absolutly no chance of closing up so if the wearer should wish not to wear earrings for any length of time this would be perfectly possible. <IMAGE>

Filed: 1992-03-26
Abstract: Apparatus for separating plant material comprises a set of blades (16) protruding upwardly from a circular base plate (12), and a set of dividing rods (20) projecting downwardly from a supporting ring (18). In use, a container of plantlets is placed on a dish (9) between the base plate (12) and the ring (18), and the ring (18) is moved downwardly, carrying the rods (20) downwardly into the plant material, and forcing the blades (16) upwardly into the plant material. The ring (18) is then rotated relative to the base plate (12), the spacing and positioning of the rods (20) and blades (16) being such that the rods and blades interpenetrate and pass between each other during the rotation. The rotary movement effects separating of the plant material by a combined action of teasing apart, splitting and cutting, of the plant material.

Title: A process for continuous production of polyurethane foam blocks
Inventor: MCHENRY JOHN
IPC: B29C44/28
Filed: 1993-02-24
Abstract: A production plant (1) carries out a process for producing polyurethane foam blocks. Reactants which are fed under high pressure to a mix head (2) are re-circulated through tanks (4, 7) by pump and valve assemblies (9, 10) until the pump attains an operating speed before high pressure delivery begins. The base (14) of the conveyor (13) is lined and the lining may comprise a lower film of coated paper, above which is a polythene film which helps to seal the gaps between the base and side walls of the conveyor which are also lined. A water spray is generated approximately 4m - 10m from the mix head (2) to neutralise gaseous TDI emitted from the foam and to help in the action of a cutting blade at the end of the process. Before the production proper begins, a test reactant mixture is delivered through a valve (35) and an outlet (36) to a test container and parameters of the process are adjusted accordingly before it begins. Some reactants are pumped under low pressure and others under high pressure to the sides of a mixing chamber (30) of the mix head (2). <IMAGE>

Title: Hydrophones
Inventor: MAAS STEVEN J
IPC: H04R1/44
Filed: 1993-04-29

Title: A method for recovery and transportation of electrorheological fluids
Inventor: VARLEY CAMERON JOSEPH
IPC: C10M171/00
Filed: 1993-09-29
Abstract: A fluid, such as crude oil, is transported by being converted into an electrorheological fluid and by then having an electrical field applied across the fluid to stiffen it to an extent that allows it to be moved in the stiff state. The field may be applied by a collector that includes spaced plates connected to a voltage supply to allow the plates to be energized and de-energized. Fluids that are inherently electrorheological can also be transported in this way. <IMAGE>

Title: Programmable controller and methods of setting and displaying its internal information
Inventor: ITAMI SHINZI
IPC: G05B9/02
Filed: 1994-03-17
Abstract: A programmable controller has a programmable controller unit 3104 and a peripheral device 101 which facilitates defining and managing set values of both the internal devices of the programmable controller and the upper and lower limit values by allowing the programmable controller unit and the peripheral device 101 to store set values as reference values for judging the magnitudes of current values of information and updating these values under the control of a sequence program. Further, the programmable controller and peripheral device facilitate the consecutive display, real-time display, etc. of the contents of internal device (e.g. counters, timers,) by displaying sequentially the contents of these internal devices at predetermined intervals under the control of a sequence program. Additionally this invention allows numerically represented character information stored in internal devices of a programmable controller to be displayed in the form of characters by a simple peripheral device. This display operates under the control of a sequence program and converts stored internal information into character information which indicates display shapes. <IMAGE>

Title: Fuel system for a gas turbine engine
Inventor: SMITH TREVOR STANLEY
IPC: F02C9/26
Filed: 1995-10-07
Abstract: A fuel system for a gas turbine engine comprises a metering valve (8) which supplies fuel via a pressure raising and shut-off valve (10) to a fuel manifold of the engine. A manifold drain valve (20) has a control line (24) connected to the outlet of the metering valve (8) so as to connect the manifold to a drain tank when the pressure at the outlet is below a threshold value and so as to prevent draining of the manifold when the pressure at the outlet is above the threshold value. The manifold does not, therefore, drain unless the metering valve is closed, thereby avoiding complete engine shut-down when only a momentary curtailment of fuel supply is required (eg. to correct an overspeed condition). Details of individual valve constructions are also disclosed (figures 2-5).

Title: Driving grey scale display of a matrix LCD
Inventor: CHOI SUN-JUNG
IPC: G09G5/00
Filed: 1995-10-12
Abstract: An n-bit error-diffused value of N-bit picture data is determined, where n is smaller than N. The N-bit picture data is converted into an optimum M-bit code, where M is larger than or equal to N, taking into account device and system characteristics. n Bits of the converted picture data are error-diffused and picture data of M-n bits, with n bits being error-diffused, is displayed. The method reduces the scanning and data electrode driving signal voltages and the driving voltage magnitude variation for respective sub-frames and improves picture quality. A display driver implementing this method is implemented by adding an encoder 1, error diffusion logic 2 and a buffer memory 3, to conventional circuitry.
