Title: Bobbin holder with rotatably mounted centring plates
Inventor: DAMMANN PETER
IPC: B65H54/553
Filed: 1988-11-03
Abstract: Bobbin holder with rotatably mounted centring plates. In the known bobbin holders, the centring plates are cylindrical and are matched to the tube inside diameter. To clamp the tube, they therefore have supporting rings, the diameter of which is equal to the tube outside diameter or larger than this. If inaccurately calibrated bobbin tubes are used, there is the risk of inaccurate clamping. The new bobbin holder is to guarantee accurate clamping and a reliable catching of the thread. The centring plates are cone segments. The smaller diameter is smaller than and the large diameter larger than the tube inside diameter. Provided on the circumferential surface is at least one recess, as a groove, slot or flattening, of which the clamping wall pointing outwards extends helically, opposite to the rotation of the tube, from the larger centring-plate diameter to the smaller up to or under the tube edge. The conical shape of the centring plates guarantees reliable centric clamping, and the thread is caught reliably by the recess or recesses.

Patent DE-3910508-A1 (DE)
Title: Method and device for measuring a time period
Inventor: SCHULZE WOLFGANG
IPC: H03K5/131
Filed: 1989-04-01
Abstract: A time period (tx) whose start is defined by a first control signal (CL1) and whose end is sampled by a second control signal (CL2), is intended to be measured with the aid of a base time (tm) used as a time increment, in such a way that long-term variations in the base time are not included in the measurement. Before commencing the actual measurement, the second control signal (CL2) is triggered earlier than the first control signal (CL1) in a first measuring run and the first advance time (na.tm) is measured by sampling with the base time (tm). In a subsequent second measuring run, the advance time is increased by a known fixed time value (tf) with respect to the first advance time and the second advance time resulting therefrom is measured in the same way. The base time (tm) can be determined from the two measurement results. The method can advantageously be used in testing the time response of digital (switching) circuits. <IMAGE>
Patent DE-3910666-A1 (DE)
Title: Hydraulic bucket tappet
Inventor: SEEGERS HANNS DIPL ING
IPC: F01L1/25
Filed: 1989-04-03
Abstract: In hydraulic bucket tappets in which a clearance adjusting element is arranged concentrically in a bucket-shaped housing and a curved seal between the said housing and the clearance adjusting element seals off the oil reservoir located inside the bucket tappet, the said seal is heavily stressed due to the volume adjustment, the relative movement of housing and clearance adjusting element and the inertial forces and therefore tends to fail prematurely. According to the invention this is overcome in that the seal is fixed to curved reinforcing elements which are arranged between the housing (2) and clearance adjusting element (8), and that at least one elastic hollow body is provided in the oil reservoir inside the housing (2). The seal acts exclusively as reinforced U-type bellows to compensate for the relative movements of clearance adjusting element (8) and housing (2), whilst the volume adjustment is absorbed solely by deformations of the hollow body. Other embodiments provide for the combining of seal and hollow body into one unit. Bucket tappets of this type are independent of an external oil supply and are used in internal combustion engines with overhead camshaft. <IMAGE>
