Title: Method and apparatus for controlling density profile in a concrete extruded slab
Inventor: MARTENS ERNST
IPC: B28B1/08
Filed: 1992-02-11
Abstract: In the extrusion of hollow core concrete slabs, the density profile across the slab is controlled by the vibration of a hammering plate (22) forming one side of a packing chamber (21) through which the concrete is extruded. Vibrations are imparted to the hammering plate (22) by a vibrator (36) that acts to produce vibratory motions in the plate that are not parallel to the direction of extrusion. With two vibrators (36) producing vibratory components both in the direction of extrusion and outwardly to opposite sides of the packing chamber, the flow of concrete to the side edges of the slab is augmented. In an auger-type extruder, this allows the outer augers (20) to be run at a slower speed than otherwise, thus increasing their service life. The vibratory frequency may also be reduced considerably, thus reducing the noise generated by operation of the apparatus. <IMAGE>

Title: Foot-operated valve
Inventor: CHANG FANG-HSIUNG
IPC: F16K31/62
Filed: 1994-07-12
Abstract: A foot-operated valve includes a valve set with a hollow seat (20) and a push rod (30) that extends movably and slidably into the hollow seat (20) and that has a bottom end with a plug (50) provided therearound. The push rod (30) is biased so that the plug (50) blocks normally a distal bottom end of a tubular sleeve (60) Fig 4 that is secured in the hollow seat (20). When downward pressure is applied on the push rod (30), the plug (50) ceases to block the bottom end of the tubular sleeve (60) to permit communication between outlet and inlet pipe connectors (23, 24) of the hollow seat (20). A retaining plate (100) is biased by an extension spring (110) to engage the push rod (30) when the push rod (30) moves downwardly, thereby maintaining communication between the outlet and inlet pipe connectors (23, 24). A switch assembly is operable selectively so as to pull the retaining plate (100) away from the push rod (30) to permit the push rod (30) to move upwardly and enable the plug (50) to once more block the bottom end of the tubular sleeve (60). <IMAGE>

Title: Flow control for waste water purification
Inventor: KICKUTH REINHOLD
IPC: C02F3/04
Filed: 1995-01-07
Abstract: The inflow control means comprise either a contact buffer or a buffer reservoir and pump means or both in combination with the inlet of a soil-based filter bed 5 like a root space installation. The contact buffer is in direct flow communicating contact with an upper section of the filter bed on the infiltration side and dimensioned in adaptation to the throughput capacity of the soil-based filter bed such that variations in the waste water inflow are evened out. The same effect is achieved by the buffer reservoir 10 and pump means 11 wherein the pump delivers waste water from the buffer reservoir to the inlet and excess waste water is returned from the inlet to the buffer reservoir through a return line 13 having a receiving end at a level which is preferably adjustable relative to the top surface of the filter bed. For evening out large differences in the waste water inflow, the contact buffer and the buffer reservoir including the pump means are preferably combined such that the buffer reservoir flow communicates with the contact buffer. The pump means, then, are adapted to be operated in the event that the variation in the waste water inflow exceeds the predetermined waste water inflow variations buffered by means of the contact buffer. <IMAGE>

Title: Method for ensuring effective braking of vehicles under wet conditions
Inventor: WOLFSRIED STEPHAN
IPC: B60T7/12
Filed: 1995-07-20
Abstract: A method for ensuring effective braking of vehicles under wet conditions, comprises sensing that a wet condition is present (e.g. by operation of a screen-wiper switch W), and effecting a temporary automatic braking operations of at least one brake (e.g. for 10-30 seconds), in such a way that vehicle deceleration cannot be perceived by the driver. Automatic braking takes place if a wet condition is sensed (step 102), the time T1 since operation of the switch W exceeds a preset time St (step 108), the vehicle speed V exceeds a preset speed Sv (step 120), and the brake temperature TB is not greater than a preset value Sb (step 112). Steps 110-112 are optional or they may replace steps 103 and 106-108. Brake pedal operation terminates automatic operation as does operation of ABS and traction control. The engine drive torque can be regulated during automatic braking such that the vehicle does not decelerate. <IMAGE>
