Abstract: 1. An electronic commutating device for direct current machines with a plurality of phase-windings having semiconductor switching elements which can be controlled into the blocking state via their control electrodes, and wherein each of the semiconductor switching elements is suddenly switched over to the conducting or blocking state, as the case may be, by "on" and "off" signals derived from the position of the rotor, characterised in that the "off" signal for the respective semiconductor switching element (4 to 6) of the phase-winding (1 to 3) which is to be disconnected is delayed compared with the "on" signal for the respective semiconductor switching element (4 to 6) of the superseding phase-winding (1 to 3) the delay being so calculated that the current in the phase-winding to be disconnected is completely or partially damped as a result of the equalizing current caused by the machine EMF.

Granted: 1985-08-01
Abstract: A measuring instrument for the depth of the periodontal cavity comprises a probe needle (2), a needle holder (3) and a handle (1). The needle (2) with the needle holder (3) is restrictedly pivotable from a start position determined by an abutment against the action of a bias spring, the deformation of which caused by the needle movement causes no substantial change of the spring force. To this end the needle holder (3) and the handle (1) each are attached to parts of a hinge (4). The hinge parts (5, 6) are biased to the closed position of the hinge (4) by a spring (8, 12, 13, 14) with a spring characteristic which is substantially flat at least within the restricted pivoting range of the hinge. 
<??>In this manner the hinge of the measuring instrument can be made compact and especially flat whereby the user of the instrument has a good view on the probe position under all circumstances. The measuring instrument is constructively simple, can be manufactured relatively cheap and can be more easily sterilized.

Title: Shell sealing for separating a cylindrical body from a bore containing the same
Inventor: HAUSER HERBERT JOSEPH
IPC: F16J15/02
Filed: 1985-01-17
Granted: 1987-10-15
Abstract: A seal for an internal combustion engine having a fuel injection nozzle positioned within a stepped bore formed in a cylinder head. The fuel injection nozzle contains an exterior stepped configuration with a shoulder formed between its steps. The seal includes a ring circumferentially positioned around and contacting the smaller diameter portion of the fuel injection nozzle. The ring has a flat first end which abuts the shoulder of the fuel injection nozzle and a tapered second end which contacts the smaller diameter portion of the stepped bore. The taper is formed on an exterior surface of the ring and has a maximum outside diameter which is slightly larger than the smaller diameter portion of the stepped bore. The seal also contains an outwardly projecting bulge formed between the first and second ends. The bulge permits the first and second ends to move axially relative to one another as the fuel injection nozzle is axially adjusted within the cylinder head and during normal engine operation. The seal serves to prevent combustion gases, which are generated in the cylinder, from flowing into the larger diameter portion of the stepped bore.
