Patent DE-19604578-A1 (DE)
Title: Dry mortar mix delivery system for building or construction site
Inventor: ARNOLD JOSEF
IPC: B05B7/14
Filed: 1996-02-08
Abstract: The system is driven by a continually operating compressor which provides the driving air to deliver mortar through a delivery hose from a storage vessel and also a by-pass flow directly to the delivery hose in the case of a blockage. The flows are controlled automatically. A storage vessel (6) is filled with dry mortar material, by a hopper from a silo, which is delivered to the required point by a hose (5) connected to an outlet (4) which contains a junction (9) to which a by-pass hose is connected.  A perforated dividing floor (7) is provided which permits air to pass but not the mortar material and an inlet (8) is connected to a hose (13) to a compressor (11) through a valve (16). By-pass air is delivered through a hose (14) connected to the compressor through valve (17). A pressure sensing and controlling unit (18) operates both valves so that at lower set pressure delivery valve (16) is opened and by-pass valve (17) is closed. If blockage occurs in output, pressure rises to higher set value and valves are inverted until pressure falls to the lower value.

Title: Variable valve control for IC engine
Inventor: DUMMANN HANS-PETER
IPC: F01L1/356
Filed: 1996-03-02
Abstract: Adjustment of the rotation axle of the valve-operated shaft drive (2) is achieved through a sectional rotation of the bearing unit (1) about a rigid or movable axis. The bearing unit has a bend, due to a right or left rotation, supported against the cylinder head. A trial movement on the bend plane forms frictional forces that are produced from the valve-operated shaft (4). Alternating moments, from the sectional rotation of the bearing unit, are reduced by a constant factor. Frictional-type bearing of the bend plane may be set entirely or partially via a roller bearing. The bearing unit may be disabled in two or more positions via a system.

Patent DE-19610997-A1 (DE)
Inventor: MARTEN STEFAN DIPL ING
IPC: H04R9/02
Filed: 1996-03-21
Abstract: The magnetic air gap 4 into which the moving coil 3 projects is acoustically sealed by a solid or liquid medium such as ferrofluid. The coil 3 divides the air gap 4 into an inner gap 14 and an outer gap 15 and the sealant may fill either both air gaps or only the outer air gap 15. The sealant is used in electrodynamic acoustic transducers 1 with inner beads 7 and prevents an acoustic short circuit between the inner air gap 14 and the air volume 18 in front of the transducer membrane 2. The acoustic seal affects the frequency response of the transducer, particularly the low frequency response and provides a nearly constant acoustic pressure gradient over a large frequency range (Figure 4). The transducer described may be used in hearing aids or headphones.

Title: Hydraulic pressure control for motor vehicle automatic transmission system
Inventor: KOZAKI TETSUJI
IPC: F16H59/42
Filed: 1996-03-26
Abstract: The hydraulic pressure control regulates the servo force for the gearchange clutches from a start point to a programmed point to cover the time delay to reach the new gear ratio. A simple hydraulic control monitors the output speed of the engine (17) and the output speed of the transmission (7) to provide a constantly updated transmission ratio for the processor control. The sensors are simple tachometer type of sensors which provide instant read-outs. The gearchange sequence is monitored and compared with programmed values to enable the control to correct for the effects of viscosity ie. to achieve programmed gearchange times with different viscosities of the hydraulic fluid.

Title: Collision protection for vehicle occupants
Inventor: SUGIYAMA TAKAMI
IPC: B60R21/16
Filed: 1996-10-04
Abstract: The improved control system for the collision protection has the output of impact sensor processed to determine if a genuine collision has occurred or if a sharp impact has been detected which does not warrant a release of the protection system. The control system adds a varying signal to the output of the impact sensor, via a subtraction/integration circuit, and integrates the combined signal to provide the control signal. The control system uses simple logic circuits to differentiate between the different types of impact, and the effect of sharp cornering, etc. to prevent premature release of the collision protection system. The protection systems include airbags and safety belt tensioners.
