Patent EP-0402474-A1 (EP)
Inventor: MORIYA YUKIO KOMATSU OSAKA PLA
IPC: E02F9/22
Filed: 1989-11-29
Abstract: A service valve circuit in a hydraulic excavator having a predetermined actuator operation valve and which is connected for operating a special attachment. A confluence valve (17) which effects electromagnetic proportional flow-rate control is provided in a confluence circuit (16) that makes communication betwen the inflow circuits (3F, 3R) of two variable pumps (2F, 2R). There are further provided an electric switch (21) which turns on or off the confluence valve (17) depending upon a required flow rate, and a volume (22) which adjusts the flow rate after passing the confluence valve (17) over a range of a maximum of 1 to 2 pumps depending upon the required flow rate. The necessity of confluence for the flow rate required by the special attachment (e) or the confluent flow rate is set in advance to elimi- nate excess or lack of confluent flow rate. Therefore, there is no need of adjusting the flow rate depending on the number of revolutions of the engine, and no delay develops in the operation even when the operation of special attachment is switched into the turning operation or the running operation.

Abstract: A countercurrent swimming pool is specified which serves, for example, for swim training for high-performance sportsmen. The countercurrent swimming pool has a swimming channel (1) through which water is to flow, a return flow channel (2) and a pump device (3) which takes in water from the swimming channel (1) and resupplies it to the swimming channel (1) via the return channel (2). With the aim of achieving a flow through the swimming channel (1) that is as free as possible from turbulence, the outlet opening (4) of the pump device (3), which radiates essentially vertically upwards, opens into a tower (5) which is arranged thereabove and which is connected in terms of flow to the swimming channel (1) via an acceleration section (6). The increasing of the initial flow velocity of the circulating water is served by the acceleration section (6), which tapers in cross-section in the flow direction. <IMAGE>

Abstract: A battery grid pasting machine (8) with a paste hopper (14) having an orifice plate (16) at the bottom, and a lower paste feed box (12) beneath the hopper (14) having an orifice plate (16) at the top. The orifice plates (16,30) define a clearance passage (32) through which grid panels are advanced by feed rollers (36,38). Paste in the hopper (14) is fed downwardly through registering slots (40,48) in both orifice plates (16,30) by a hopper feed roller (36). A back-up roller and a reserve paste reservoir in the lower paste feed box (12) cooperate with the feed roller (36) in applying paste to both sides of a grid advanced through the clearance passage (32). The lower paste feed box (12) can be raised or lowered to adjust the vertical dimension of the clearance passage (32). The hopper feed roller (52,66) and back-up roller (150) have knurled peripheries provided by preferably a diamond pattern of crossing grooves. A top grid drive roller is mounted on a pivoted bracket (84) which is biased to force the drive roller into pressure contact with the tops of the grids.

Abstract: A security device (1) for trolleys, especially shopping trolleys, has elements for releasing an introduced and retained coin (50) and for coupling and uncoupling the trolley to and from a fixed collecting point or to and from another properly parked coupled trolley. Furthermore, in the security device (1) there is a locking part (2) which is so pivoted by the insertion of a key (8'), fastened, for example, to another properly parked and coupled trolley, that the inserted key (8') is safely held and securely locked solely by the locking part (2); the previously introduced coin (50) retained in the security device (1) is simultaneously released. 
<??>This security device (1) guarantees that a tensile stress from the adjacent trolley or trolleys, exerted via a chain (82') and the key (8') attached to it, is absorbed exclusively by the locking part (2) mounted pivotably in the security device (1), without the remaining functional elements of the security device (1) thereby being in any way subjected to stress and influenced in terms of their operating capacity.

Abstract: Phosphorylated plasminogen activator, such as phosphorylated pro-urokinase (pro-u-PA), which is substantially free from unphosphorylated plasminogen activator, may be obtained by phosphorylating unphosphorylated plasminogen activator with a phosphorylating enzyme or by separating phosphorylated plasminogen activator from a mixture of phosphorylated plasminogen activator and unphosphorylated plasminogen activator. Phosphorylated pro-u-PA, which is substantially free from unphosphorylated pro-u-PA, is converted by plasmin into phosphorylated u-PA. The phosphorylated plasminogen activators such as phosphorylated pro-u-PA, u-PA and t-PA are useful as thrombolytic agents.

The coil assembly for use in the transponder includes a primary coil (156), the leads of which are left floating, and a secondary coil (158) which has its leads connected to an integrated identification circuit within the transponder. Both coils are wrapped around the same coil forming ferrite rod, and are configured to resonate at the same operating frequency, such that the quantity of energy which can be transferred between the transmitter and the transponder is maximized.   <IMAGE>
