Patent SE-8703208-L (SE)
Inventor: CHMELA F
IPC: F02B23/10
Filed: 1987-08-18
Abstract: A spark-ignition, air-compressing, internal combustion engine having a combustion chamber in the shape of a body of revolution with a constricted opening in the piston crown. The injection nozzle is located in the cylinder head near the edge of the combustion chamber and the spark plug, opposite the injection nozzle, extends into the combustion chamber at the top dead center position of the piston. Mixture formation is predominantly by deposition of the fuel on the combustion chamber wall. In such an internal combustion engine, it is desired in applying the concept to a supercharged engine to satisfy the enhanced requirements with respect to mixture formation reliably in all ranges of operation, whereby a further improvement of ignition stability is also to be provided. This is essentially achieved by the special shape and proportioning of the combustion chamber, and in particular by the use of two arcs to form the side wall thereof, and a third arc, which joins the side wall, to form the bottom.

Abstract: A pocket transceiver can be, for example a portable wireless telephone apparatus small enough to be put into a pocket of a user. The apparatus operates at a low power level. The pocket transceiver as an independent unit only handles signals at a low power level and is suitable for communication over close range. The pocket transceiver can also be used as a telephone apparatus for communication over long range, such as a mobile transceiver in a vehicle, by being connected to an adapter, which includes a power amplifier and a power controller for selecting an output power level out of multiple levels in response to an instruction from a transmitting-receiving unit of the pocket transceiver.

Abstract: The present invention is for a device for use by electrostatic powder coating. The device is intended for charging and application of powder. The device according to the invention has smaller outer dimensions than prior art devices due to a specially designed charging channel. This also makes it possible to obtain a large flow of powder and a smooth coating. The device is less subject to wear and maintenance and repair, e.g. exchange of worn parts is simple. The essential part of the invention is the mixing channel. In the embodiment shown in the figure the channel is formed by several small building elements, inner elements (2) shown in figure 4 and outer elements (4), as shown in figure 3. The building elements are held together by a central rod (3) and a surrounding outer tube (5). This in turn is surrounded by a slit (6) and an outer casing (7) shaped as an outer tube. The inlet (11) and the die (12) are also attached to the tubes (5 and 7).

Abstract: The invention relates to a method of transmitting data in a radio system from a transmitter to a receiver, and to a radio system using the method, a radio transmitter and a radio receiver. A transmitter (260) comprises a channel coder (202) for channel coding a data block into a coded data block by using a selected channel coding and for puncturing the coded data block by using a first puncturing pattern, and transmission means (204) for transmitting the coded data block punctured by the first puncturing pattern to a receiver (264). The receiver (264) comprises a channel decoder (218) for decoding the received coded data block, means (224) for detecting a need for retransmission of the received coded data block, and means (204) for transmitting a retransmission request of the coded data block to the transmitter (260). The channel coder (202) increases the code rate of the coded data block to be retransmitted by puncturing the coded data block coded by the channel coding of the original transmission by using a second puncturing pattern comprising fewer symbols to be transmitted than the first puncturing pattern. The transmission means (204) transmit the coded data block punctured by the second puncturing pattern to the receiver (264). The receiver (264) comprises means (222) for combining a received coded data block (216) punctured by the first puncturing pattern and a received coded data block (220) punctured by the second puncturing pattern. The channel decoder (218) decodes the channel coding of the combined coded data block.
