Title: Fuel oil chamber filter for oil=fired heating systems
Inventor: RAMBACHER GERHARD CHRISTIAN DI
IPC: F23K5/18
Filed: 1996-08-03
Abstract: An injection-moulded immersible polyethylene body (2) reaches down from the filter cover (14) into the entry chamber (22) to screen the filter element (18) casing space (36) against gas entry from the adjoining radial area (39,40) of the chamber.

Entry to the chamber is through a passage in the cover and the casing surface of the body (20) and filter cup may form a further passage for the incoming fuel oil. The body may gastightly cover the filter casing sector apart from the open-rimmed annular gap (37) at the end furthest from the filter. The body can thus be inserted via its radiating shoulder (34) to fit the filter concerned. The filter element itself may consist of a metal gauze or cloth or again a sintered polyethylene weave, and the filter can be turned in on itself at the immersed endface to enlarge the useful filter surface.

Title: Solar pump with liquid working piston and simplified collector
Inventor: STIERHOF HUBERT
IPC: F04F1/02
Filed: 1996-08-03
Abstract: The solar pump has a liquid working piston and simplified collector.

Patent DE-19641840-A1 (DE)
Inventor: DUBHASHI AJIT
IPC: H03B1/00
Filed: 1996-10-10
Abstract: When commutation current begins to flow in the anti-parallel diode Dp in the lower part of a half-bridge, a negative voltage transient appears at the node Vo due to inductances Ls1 and Ls2, causing failure of the driver IC. These inductances are reduced by minimising conductor lengths and by other layout and wire bonding techniques. The bootstrap capacitor Cb and the power supply capacitor Cvcc are increased; Cvcc is preferably about ten times the sum of all the bootstrap capacitors in the circuit. The resistance Rb in the bootstrap charging circuit is minimised, and may be eliminated. Finally, a resistor Rcom may be added in the negative supply line 41 to reduce current flow in the substrate diode Ds. the driven devices may be IGBTs or power MOS transistors.

Patent DE-19730122-A1 (DE)
Title: HF pulse sequence generation method for nuclear magnetic resonance measurements
Inventor: LEROUX PATRICK L
IPC: A61B5/055
Filed: 1997-07-14
Abstract: The method involves entering the appropriate data for the required pulse profile.  The initial weighting function is calculated and a set of the so-called SLR polynomials is calculated, using a least mean squares procedure incorporating the initial weighting function and the required pulse profile.  The inverse SLR transformation is used to generate the HF pulse envelope curve.  This pulse sequence can be generated in a magnetic resonance imaging system to acquire data on an object.  The error in the values of the SLR polynomials can be determined, and the calculations repeated until the error is reduced below a set maximum.  The user may, alternatively, enter the required phase profile for the calculation.
