Title: Device for fastening a grinding wheel on the grinding spindle of a portable angle grinder
IPC: B24B41/04
Filed: 1984-02-18
Granted: 1986-01-09
Abstract: The subject of the invention is a device for fastening a grinding wheel (23) in portable angle grinders, which device permits the fastening to be released without an auxiliary tool. The device essentially comprises a hollow grinding spindle (16), a feed spindle (20) which is displaceably mounted therein, a displacing device (6) and two flanges, such as a counterflange (22) and nut (21), which receive the grinding wheel (23) between them. In order to release the nut (21), the feed spindle (20) is displaced in the direction of the flanges by actuating the displacing device (6), with the result that the nut (21), connected to the feed spindle (20) via a threaded pin (19), is lifted from the grinding wheel (23). The nut (21) can then be unscrewed by turning by hand. <IMAGE>

Patent DE-4234145-C1 (DE)
Inventor: HILL WOLFGANG
IPC: H02K41/03
Filed: 1992-10-09
Granted: 1994-02-03
Abstract: Known conductor strands which can be set into the grooves of linear motors or disk armatures, do not sufficiently occupy the space available in the groove and winding head in multi-phase machines, and thus increase the volume and weight of the machines. For high power and force densities, the conductor strands should allow the available space to be fully occupied. The number of different conductor strand shapes should be minimised to reduce production costs. According to the invention, the conductor strands (13 to 16) prefabricated in a single piece expand in the overlapping zones in the direction of the depth of the groove, so that the conductor cross-section is variably adapted to the available space. By using pairs of conductor strands (13 and 14) without loops and mutually offset by a pole pitch in a groove, a high occupation of the space available in the winding heads and short conductor lengths are achieved. Symmetrical winding head allow the conductor strands to be easily mounted and dismounted any time in the direction of the depth of the groove. The number of different conductor strand designs is limited to twice the phase number thanks to the use of mirror symmetries. This winding is suitable for motors and generators in which a reduced overall height and a high power density are of advantage.

Title: Method and device for testing filter elements using a water intrusion test
Inventor: GEHNE INGO
IPC: G01N15/08
Filed: 1993-11-20
Granted: 1994-12-08
Abstract: The invention relates to a method for non-destructive in-line or off-line testing of filter elements comprising hydrophobic porous filters using a water intrusion test, and a testing device for carrying out the method. One or, at the same time, more than one filter elements such as tube filters (plugs), capsules or cassettes, located in a filter housing, can be tested. By virtue of the method, measurement errors which are caused, during determination of the reference volume by compacting/ decompacting processes of the filter elements due to the pressure differences to which the filter elements are exposed according to the prior art, are ruled out. According to the invention, in order to carry out the test, water is applied to the filter elements located in a housing by means of a gas which is under a test pressure, such that a gas pressure corresponding to the test pressure is established inside a known total net volume of the testing device and, by measuring the pressure drop of this gas, the quantity of intruded water is calculated. The method can be used for validating and integrity testing of filter elements in the context of quality assurance of their production, in sterile filter systems for aerating and deaerating fermenters, sterilisers, freeze-driers or sterile tanks, in filtration systems for hydrophobic fluids or in splitting systems for oil/water separation. <IMAGE>
