Title: Bite indicator
Inventor: CRUZ JOSEPH LUIS
IPC: A01K97/12
Filed: 1987-09-17
Abstract: A device for indicating the movement of a fishing line comprises a thin resilient support 5, adapted to carry the line 6 in frictional contact, and coupled to an electrical sensing means adapted convert the vibrations caused by the movement of the line against the support into electrical signals. The electrical sensing means is a vibration detector, such as a piezo-electric detector, which is mechanically coupled to the resilient support and senses vibrations induced in it by the movement of the line. The thin resilient support is made of a material having sufficient thickness to support the line and sufficient hardness to resonate when stimulated by the frictional movement of the line in contact with it. The alarm system is triggered when the line moves over the support faster than a preset rate and provides an audible and/or visual warning. <IMAGE>

Title: Raster scan waveform display with pixel intensity gradation
Inventor: ALAPPAT KURIAPPAN PAUL
IPC: G01R13/34
Filed: 1989-01-05
Abstract: An analog input signal to a digital oscilloscope is sampled and digitized to form a representative waveform data sequence. A waveform is then displayed on a screen of the oscilloscope to represent the magnitude of the waveform as a function of time as indicated by the waveform data sequence. The waveform is formed by a set of vectors, each vector comprising a straight line between two points on the screen at elevations representing magnitudes of two successive input signal samples, and at horizontal positions representing timing of the two samples. The screen provides a display organised into an array of pixels, each of which may be illuminated with variable intensity, and each vector is represented by illuminating pixels having center points bounding the trajectory of the vector on the screen. The intensity of each such illuminated pixel is modulated in accordance with the distance between the pixel and the vector trajectory.

Title: Lubricating a reduction gear assembly in a gas turbine engine
Inventor: HADAWAY EDWARD STAFFORD
IPC: F01D25/18
Filed: 1989-07-21
Abstract: A turbofan gas turbine engine (10) comprises a fan rotor (32) driven by a core engine (11) via a shaft (36) and a reduction gear (38). A lubricant source (63) is arranged to supply lubricant to the reduction gear (38) to lubricate gear teeth and bearings (52) in the reduction gear (38). An annular collector (76) is positioned coaxially around the reduction gear (38) and is secured to the fan rotor (32) and is driven by the reduction gear (38). The annular collector (76) is arranged to collect lubricant leaving the reduction gear (38) on its inner surface. A number of static scoops (82) collect lubricant from adjacent the inner surface of the annular collector (76) to return the lubricant to valves (86). The valves (86) allow the lubricant to return to the lubricant source (63) in normal operation. If the lubricant source (63) fails to supply lubricant to the reduction gear (38) the valve (86) returns the lubricant to the reduction gear (38) to allow the reduction gear (38) to operate for a period of time without a supply of lubricant. <IMAGE>

Patent GB-917734-A (GB)
IPC: D21H19/18
Abstract: 917,734. Coating surfaces; coating apparatus. WEST VIRGINIA PULP & PAPER CO. July 21, 1960 [Nov. 16, 1959], No. 25473/60. Class 95 [Also in Group VIII] A method of giving a fibrous sheet, e.g. a carton blank, a glossy wax coating comprises applying the wax in molten state, at 11, to the surface of the sheet, allowing the wax at least partially to solidify, at A, passing the coated sheet through a zone B of radiant heat to cause the wax to reflow, removing -the sheet from the zone B before complete remelting, and cooling the sheet, e.g. by passage about a drum 19 having a polished, chromium-plated surface. The process is continuous, the blanks being fed in succession at 10 and carried by an endless conveyer 17 through the zones A, B to the drum 19, which is cooled internally by water, an adjustable air jet 21 serving to remove the sheets from the drum 19. The nozzle 21 is carried by a bar 22 fixed to members 23 which are angularly adjustable about a bearing block 24 on the frame 27. The wax is paraffin wax containing 3 to 50 % polythene, and silicone oil may be added to the wax or spread on the drum 19. Microcrystalline and unspecified resins may be added in amounts up to 10%. In a modification, the drum 19 is omitted, cooling taking place in ambient air or by water sprays. Both sides of the sheet may be coated, the lower side not being given a gloss.
