Abstract: 1532789 Hydrostatic transmission control BOFORS AB 17 Dec 1975 [18 Dec 1974] 51718/75 Heading F2W In a drive arrangement for an artillery piece wherein a pair of hydrostatic transmissions each comprise a variable displacement swash-plate pump 1, 2 and associated fixed displacement swash-plate wheel motor 5, 6, one pump 1 is selectively connected by a valve 12 either to its wheel motor 5 or to additional motors 13, 14, 15 for respectively aiming, loading and firing the artillery piece. Servos 20, 21 which compare a control pressure from a fluid amplifier 27 with pump delivery pressure acts on pilot valves of follow-up servo motors that adjust pump displacement to maintain pump delivery pressure equal to the control pressure. When the valve 12 connects the pump 1 to the motors 13, 14, 15 a valve 33 isolates the servo 21 from the amplifier 27 whereupon the delivery of the pump 2 is reduced to zero. The signal from the amplifier 27 is controlled by an electrically controlled valve 26 responsive to either an electric control on a vehicle towing the artillery piece or to an electric control 31. An electronic control 30 responsive to engine speed provides a signal which reduces pump displacement on engine overload. Engine driven pumps 7, 8 supply make-up fluid and control pressure. In Fig. 2 (not shown) each transmission is provided with high pressure relief valves (42, 43) and flushing valves (44, 45). In addition the pump displace. ment may be controlled manually at (62, 63).

Title: Active guide comb teeth in jet weaving looms
IPC: D03D47/30
Filed: 1977-12-15
Abstract: Arranged in the wall (1) of such a drop wire, around the weft-insertion orifice (2), are at least two outflow orifices (3, 3'), through which streams of pressure medium flow into the weft-insertion channel formed by the orifices (2). The axes (5, 5') of these streams intersect planes ( rho ,  rho '), parallel to the drop wire, at points of intersection (4, 4') and form an angle ( alpha ) with a straight line (6) connecting these points of intersection. The speed of the flow of pressure medium in the weft-insertion channel thereby becomes more uniform, thus resulting in a more favourable transmission of the flow energy to the weft thread and a steadier guidance of the latter. <IMAGE>
