Title: High speed encoder and encoding method
Inventor: TOWNSHEND BRENT
IPC: H04Q11/00
Filed: 1998-11-27
Granted: 1999-07-29
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communication endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide-band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Title: Bandpass matching circuit for HF aerials - has parallel resonant circuits and voltage is measured to control coupling reactances
IPC: H03H7/46
Filed: 1969-03-27
Abstract: The bandpass matching circuit, which is used for HF aerials, has parallel resonant circuits which are variable capacitors (10, 11, 12) forming shunt circuits and they are coupled over a 90 deg. phase shifting network. Each of the two parallel resonant circuits has a device to measure the magnitude of the alternating voltage across it. The coupling reactances are altered in such a way that these alternating voltages have the correct relationship for the required transformation and the reactance of the neighbouring coupling elements is controlled by the alternating voltage across the two resonant circuits in the direction of transmission. This latter control acts as compensation.

Title: Monopolar vertically-polarised logarithmic short-wave antenna - achieves broad bandwidth by using supply transformers matched to inductance of radiators
IPC: H01Q11/10
Filed: 1969-11-29
Abstract: The antennae has a coaxial supply cable whose outer conductor is connected to a ground network while the inner conductor is connected to the radiators. Only every second radiator is directly connected to the cable's inner conductor. The remaining radiators are connected via transformers to the inner conductor. The polarity of the transformer couplings is chosen so that the radiators are in opposite phase. The inductance of the transformers for the shorter radiators is less than that calculated from theory whilst the inductance of the transformers for the longer radiators is greater than that calculated from theory. The advantage lies in smallness and quick assembly.

Granted: 2005-06-08
Abstract: In the data communication method in which the data frame transmitted from the transmission side to the reception side and the feedback frame transmitted from the reception side to the transmission side use a common format jointly, to propose a data communication method in which if there is no substantial data to be transported by the feedback frame on the reception side, the feedback frame is transmitted from the reception side to the transmission side without changing the format of the feedback frame and lowering the reception rate. In the data communication, the common format includes at least each data of the transmission data length, the transmission data, the data frame number and the repeat request frame number, and is added with the error detection code for the entirety of the data. If there is no substantial transmission data to be transported by the feedback frame on the reception side, then the feedback frame is arranged such that data unrelated to feedback information including at least the transmission data length, the transmission data and the data frame number within the feedback frame, are substituted with the predetermined fixed pattern, and thereafter an error detecting code for the entirety of the data is added thereto. Then, the feedback frame is transmitted from the reception side to the transmission side. <IMAGE>
Patent JP-S5749722-B2 (JP)
IPC: F01M1/02
Filed: 1978-03-03
Abstract: PURPOSE:To reduce the slapping noise of a piston in a piston reciprocating type internal combustion engine by providing two lubricating oil inlet ports at both sides perpendicular to the axial direction of the piston to thereby forcibly lubricate even if the piston is inclined in the vicinity of bottom dead point. CONSTITUTION:When a pump driving cam 21 is rotated upon revolution of a cam shaft 11 synchronously driven by a crankshaft 6 upon operation of an internal combustion engine, an oil pump 16 discharges oil by the projection 21a of the cam 21 in the vicinity of the bottom dead point of the piston to thereby lubricate oil from lubricating oil inlets 15, 15' into a cylinder 3. This oil is supplied to the gap between the skirt portion 4a of the piston 4 disposed at the bottom dead point and wall surface of the cylinder 3 to form relatively thick oil film within the gap by the oil thus supplied to thereby control the inclination of the piston 4 via the oil film when changing its moving direction. Thus, the piston slapping noise of the piston 4 can be reduced to hit the wall surface of the cylinder 3.
