Title: Tube end expansion tool - has holding drillings for guide pins at inner and outer flange sectors
IPC: B21D41/02
Filed: 1992-01-29
Granted: 1993-06-09
Abstract: The expansion head for a spreader tool, for hollow workpieces, esp. tube ends with a cap (2) and radially recessed guide flange (3), has a set of sector-shaped expansion pads (4) held separately by an inner flange section (5) and an outer flange section (6) with radial movement through a radial groove (7) between them. Outer flange sectors (6) have drillings (9), as well as drillings (8) at the inner flange sectors (5), to hold the other ends of the guide pins (10). Guide pins (10) are held in a press fit, in at least one of the two sets of drillings (8,9). Ring-shaped draw springs (15) are also at the outer flange sectors (6) to return the spreader pads (4) into complementary groove sectors (12). Drillings (9) for the guide pins (10), at the outer flange sectors (6), are pref. blind drillings. Guide pins (10) are notched taper pins. USE/ADVANTAGE - For the expansion of a tube end for an untreated tube end to be fitted into it or, in the case of plastics tubing to carry water and especially for floor heating, for a connecting nipple to be inserted without force into the expanded end. Expansion head, together with expanders, increases the opening angle of the spreading pads on a stroke movement of the expansion mandrel.

Title: Vehicle roof which can be opened
Inventor: FAERBER MANFRED
IPC: B60J7/00
Filed: 1993-09-09
Granted: 1995-02-02
Abstract: The invention relates to a vehicle roof, which can be opened, having a panel which can be moved along guide rails and below which there is arranged a displaceable sliding headliner (roofliner). Provided as the driver and stop system for the sliding headliner is a separate slide which is coupled in terms of motion to the panel mechanism and on which there is arranged a cantilever engaging laterally around the sliding headliner. Interacting with the stop surfaces of this cantilever are stops which are arranged, on the one hand, close to the front edge of the panel, on the upper side thereof and, on the other hand, close to the rear edge of the panel, on the upper side thereof. In the fitted condition of the roof the cantilever is always located between these two stops. By virtue of the arrangement according to the invention stops for the sliding headliner on the lower side of the panel are dispensed with which makes it possible for the overall height of the system to be reduced and, furthermore, a water channel, which reaches under the rear edge of the panel, is kept free of all forces which occur during the movement of the sliding headliner.

Title: Method of determining plague in arteries - uses blood pressure measurement taken at same time at upper arms and ankles while differences are plotted
Inventor: VUNDERINK ATE IR
IPC: A61B5/022
Filed: 1996-05-15
Granted: 1997-06-17
Abstract: The build-up of plague on the walls of arteries causes an increase in blood pressure. Measurement of blood pressure is often very erratic and is affected by various factors such as e.g. the 'white coat effect'. The results of experiments have shown that reliable results can be obtained by measuring the differences and/or the ratios of blood pressures measured at the upper arms and at the ankles at the same time. The results gave a clear indication if plague was present.

Title: Water purification apparatus for e.g. fish pond or fish farm effluent
Inventor: SCHULDINK HENDRIKUS EGBERT
IPC: C02F1/78
Filed: 1998-08-04
Granted: 1998-11-10
Abstract: Apparatus for mechanically and biologically purifying water and enriching it with oxygen adds ozone to the water and later removes it, any traces of ozone left in the water being removed by aeration of the water, a pump being used to mix the gas and water together, following which the gas is removed and replaced with a fresh amount of air. The apparatus significantly increases the time spent by the gas bubbles in the water and increases gas bubble life up to threefold. Within the apparatus, a first treatment step ensures a relatively long contact time between the water and ozone or another gas, along a relatively long contact length equal to up to twice the height of the pipe (10) shown in the figure. During a significant part of this contact time the gas bubbles will be under pressure, ensuring better mixing with the water. In a second treatment step the gas added in the first step is removed, a closed loop being used to return the gas via a pipe (21) to the first step, improving the overall efficiency of the treatment process.
