Title: A rotary engine having an oval rotor
Inventor: YANG CHUNG-CHIEH
IPC: F02B75/02
Filed: 1990-12-04
Granted: 1994-10-19
Abstract: Describing in simplicity, this research-the new engine (herein after referred to YTRE) is related to a kind of triangular rotation instead of linear reciprocating motion, which comprises an oval rotor (2) set to revolve along three cylinder walls combined inside a cylinder block (1) to achieve a new combustion moving function of an internal combustion engine with smaller volume, less weight, less parts but stronger power so as military vehicle or vessels can be served with better capability and efficiency in the field. The Three-in-One (three cylinders combined in one) principle means the three cylinder walls are incorporated into one unit in which a rotor rotates. It performs the function three times compared to a conventional cylinder. Since no linkage is used, and crank and most parts are commonly used, the size can be greatly reduced while the power is relatively increased. Because several intake (12) and exhaust ports (12) can be simultaneously used during each stroke, the efficiency in intaking and exhausting strokes is greatly improved which means the thermodynamics is fully utilized. The rotor is designed for circulation therethrough of air and engine oil, better lubricating and cooling effects can be achieved. The rotor is constantly disposed to contact the cylinder walls during its rotary motion around a circle, high compression ratio is simultaneously achieved as needed. <IMAGE>

Granted: 1996-03-06
Abstract: A lockable door or window comprises a door or window member mounted in a frame. The door or window member is movable preferably slidably, from an open position to a closed position in which an edge of the door or window member abuts an internal face of the frame. The edge of the door or window member is formed by an elongate capping member (8) to which is fitted a lock case (1). The internal face of the frame which abuts the edge is provided with a projection such as headed stud (20) which in the closed position engages in an aperture (9) provided in the capping member (8). The lock case (1) is operably linked to locking means for preventing disengagement of the projection (20) from the aperture (9) thereby locking the door or window member in the locked position. In the example the locking means comprises sliding plates 5, 7 which have keyhole slots 10 for engaging the headed studs. <IMAGE>

Title: Roller bearing
Inventor: NAGAI YASUAKI
IPC: F16C33/58
Filed: 1998-07-07
Granted: 2000-09-27
Abstract: There is provided a roller bearing in which contact stress between a roller and a raceway is uniformized by optimizing a configuration of a clearance between the roller and the raceway. A configuration of an outer circumferential surface (8) of a tapered roller (6) of a tapered roller bearing (1) is defined so that a clearance of Y(x)=kYp(x), which results from multiplying an equation Yp(x) for uniformizing contact stress between infinite-width plate and tapered roller by a positive number k=1.5-10, is formed between the raceway surface (4, 5) and the outer circumferential surface (8) of the tapered roller (6). The tapered roller (6) relaxes concentration of contact stresses, improving the durability.

Title: Alarm circuit for insulation loss on pipes
Inventor: LAINE ALLAN
IPC: G08B/
Filed: 1984-06-29
Granted: 1987-08-18
Abstract: An oscillator (1) applies a signal to a junction (2) which routes the signal to a transformer (TR1) and to a level detector (3). The transformer supplies an alarm wire (8) in a tube (9) and if the insulation (10) of the tube is short circuited then the load on the transformer is modified. This affects the signal amplitude at the detector and is sensed by a comparator (4) to which a reference level is applied. This activates an alarm. A second transformer (TR2) is connected in series with the first to feed part of the signal to a level detector (5) such that if the resistance in the alarm wire (8) exceeds a predetermined value then a comparator (6) will activate the alarm.

Abstract: Character contours are broken down into a series of orthogonal vectors. Pixel drop out occurs where opposite going vectors coincide. The inside pixel (410 or 440) of each vector (400 or 430) is set to the vector length if the length is greater than the set values of the inside and the outside (420,450) pixels. This procedure is repeated for all the vectors for all the contours. At completion all those pixels set to one or more are set on to produce a drop out corrected bit map which is logically OR'd with the original drop out containing bit map.

Title: Method of reducing friction between sliding surfaces
Inventor: GOJON ROGER
IPC: F16C/
Filed: 1982-01-25
Granted: 1986-12-03
Abstract: The method is for reducing friction between relatively sliding lubricated surfaces (15,17), whose main movement is rectilinear and reciprocal. The surfaces are subjected to a relative lateral force in a direction perpendicular to the direction of main movement. A low amplitude secondary rotation or tilting is imposed on the main motion, about an axis perpendicular to the direction of the main motion and to the direction of the lateral force. The secondary rotation can tend to close an 'oil wedge' formed between the two surfaces during motion.

Abstract: The character pattern generating system has a character data memory for storing co-ordinate data representing co-ordinates of a base line at a centre of a character component and for storing local outline data representing the outline of the respective character component at each co-ordinate. The system responds to a character code received from an external source for reading out the co-ordinate data and the local outline data. Outline data is generated on the basis of the co-ordinate data and the local outline data and for generating character bit pattern data from the outline data. Storing the character pattern in this form allows easy scaling of the character shape, by lengthening or shortening to the base lines.

Title: Interceptor drone with net launcher
Inventor: ZAICEVSKIJ ALEKSEJ
IPC: F41H11/00
Filed: 2020-03-06
Abstract: The drone, equipped with three or more rotors and a net launcher, is designed to mechanically block light unmanned aerial vehicles. The ratio between the drone's high engine thrust and low mass is its competitive advantage. These parameters allow it to fly fast. The net is launched in the drone rotors' thrust direction. This approach allows attacking the target, using the kinetic energy of a drone flying at full velocity. To launch the net, the rotors' thrust is used. During the attack, the rotors speed up to full rpm and are controllably detached from the drone. The kinetic energy of the rotors is converted into thrust while the propellers continue rotating by inertia. The net corners are attached to the rotors. The rotors with engines develop sufficient energy and are heavy enough to spread a net of a large area. This net size enhances the likelihood of catching the target.
