    • 940,631. Reciprocating motors and pumps. M. TERHO. May 18, 1960 [Oct. 13, 1959], No. 17605/60. Heading F1A. A pump or liquid driven motor comprises a rotatable cylinder block 2, having parallel cylinder bores 4a, 4b slidably mounting spring-loaded pistons 5a, 5b engaging through end balls 7a, 7b, the undulating track 10 of a fixed "crown" member 8. On the admission of pressure liquid e.g., to the cylinder 4a through an inlet passage 20a in a journal block 17 supporting a driven shaft 1 secured to the cylinder block, the piston 5a is urged outwardly and the ball 7a rides down a sloping surface 10a of the track 10 to rotate the cylinder block. At the same time the cylinder 4b is connected to exhaust through a passage 38b in the journal block so that the ball 7b rides up a sloping surface 10b on the track 10 to push the piston 5b inwardly in its cylinder. To prevent damage to the motor parts by ensuring that the pressure liquid entering the cylinder of the outwardly moving piston ceases prior to the piston reaching the end of its stroke and the cylinder of the inwardly moving piston is connected to exhaust prior to that piston commencing its stroke, the summits and radius of the track are made with flat portions. More than two cylinders and piston may be used, there being corresponding adjustment of the track 10.

    • This invention relates w a method of data transfer via a radio telephone network between a LAN (1) and a Mobile Station and to a data interface unit that applies the method. According to the method the LAN's data packets are formed, and the RLP control is stripped away from them, in the LAN-controller that is permanent connected to it; the data is packed into date packets in accordance with a data communications protocol and the data communications data packets are inserted into data frames of the radio telephone network when the data is transferred between the radio telephone units. The data interface unit (15) according to the invention is connected to a LAN-controller (14) on the side of the LAN (1). The data interface unit (15) incorporates a digital radio telephone unit (168) and a data adapter (17) for inserting the LAN's date packets into date frames and for extracting the data packets from these data frames when the data is transferred between the LAN and a Mobile Station that is connected to the digital radio telephone network.
