Patent DE-3062195-D1 (DE)
Title: Tube joint to be screwed into a conduit or into an apparatus for creating a closed circulation circuit of a pressurized fluid, and method for making same
Inventor: ANDREOLLA FLORIAN
IPC: F16L15/04
Filed: 1980-06-28
Granted: 1983-04-07
Abstract: The connecting piece includes a hollow many-sided head and a hollow screw which forms one piece with the many-sided head. The screw is provided with an external thread so that it can be screwed into the internal thread of a part of a line or an apparatus. A chamber-like circular recess is worked from below into the many-sided head in the proximity of the end of the thread of the screw. The circular recess is worked into the many-sided head in one operation. The cutting tool is first guided into a gate at the end of the thread of the screw perpendicularly to the longitudinal axis of the connecting piece. Thereafter the cutting tool is guided into the bottom surface of the many-sided head in parallel with the longitudinal axis of the connecting piece. In this way a guide surface at the end of the thread of the screw is formed which is free of obstacles. The insertion of the sealing ring into the circular recess is simplified because the sealing ring is guided along the guide surface into the recess without a great effort and without being injured. By tightening the connecting piece the deformation of the sealing ring is limited in an optimal way because the metal of the many-sided head lies on the metal of the part to be connected.

Title: Tracking control arrangement in a magnetic recording and reproducing device
Inventor: MORIYA RYUSUKE
IPC: G11B5/52
Filed: 1981-12-11
Granted: 1984-11-15
Abstract: A tracking control arrangement for a video tape recorder effects simultaneous recording and then simultaneous reproduction of four channel recording tracks (TRa, TRb, TRc, TRd) formed on a magnetic tape (2) under tracking control effected by detecting tracking error in dependence on the phase difference between reproduced signals from two adjacent recording tracks (TRc, TRd) of the four at the time of reproduction, the adjacent two recording tracks (TRc, TRd) being recorded with different azimuth angles. A signal delayed by a delay circuit (100) with respect to the signal recorded in one (TRd) of the two adjacent recording tracks is recorded in the other one (TRc) of the two adjacent recording tracks, thereby permitting tracking control by bimorph plate (3A, 3B) or capstan servo control (106) in dependence on the phase difference between the reproduced signals produced from two magnetic heads (1C, 1D) corresponding to the two adjacent recording tracks (TRc, TRd).

Title: Feeding device for a jet mill
Inventor: NIEMI JOUKO
IPC: B02C23/02
Filed: 1981-11-23
Granted: 1987-08-20
Abstract: The present invention is concerned with a device for preliminary crushing of a possibly clogged, material to be ground and for feeding of the said material into a jet mill containing a compressed flow of circulating grinding gas and material, so as to produce ultra-fineground admixtures to be used in industry. In prior art, exclusively ejector-type or injector-type feeder devices were used as feeder devices of jet mills of the said type, in which feeders the shifting of material into the pressurized mill takes place by means of the grinding gas. Besides their high energy consumption, another drawback of these prior-art feeder devices consists thereof that the grinding gas jet of the ejector, consisting of water vapour, sucks considerable quantities of air into the jet mill, along with the material, which causes a heterogeneous grinding result and makes the recovery of heat after the grinding difficult. In order to eliminate these drawbacks, a device in accordance with the above invention has been developed, which comprises a substantially vertical so-called plug pipe, which is at its upper end provided with a feeder funnel and which is at its bottom end, either directly or via an additional pipe, connected to the jet mill above the zone of the grinding gas nozzle. At the upper end of the plug pipe, preferably in its feeder funnel, at least one pushing means is provided which moves back and forth and which both crushes any clogged material and forces the crushed material as a tight plug through the pipe into the jet mill.

Granted: 1989-11-23
Abstract: A magnetron cathode for sputtering ferromagnetic targets. The magnet system consists of magnet poles of opposite polarity lying one within the other disposed on a basic cathode body. Between the target and the pole shoes, which consist of target material, two circumferential air gaps in the direction of the depth of the system are formed. The surfaces of projection of the magnet poles and target do not overlap. For the purpose of making the target ablation uniform while simultaneously achieving high sputtering rates, the pole shoes are separated, in accordance with the invention, each by a distance S from the magnet poles. The magnet poles lie in an area which runs from a plane passing through the sputtering surface in the direction of the depth of the system. Between the pole shoes and the target, on the one hand, and the magnet poles on the other, there is disposed a thermally conductive metal body which is in communication with at least one coolant passage and consists of a nonferromagnetic material.

A weight greater than the admissible weight acts on the other end of the shaft of the power brake. At this place damping also occurs. The weight greater than the extra weight is equal to the extra weight. The power brake has a casing (14) and a rotor (17) mounted on a hollow shaft (16). The damper (13) or a part of the torque converter engages the hollow shaft. At one end of a torsion bar (12) running inside the hollow shaft is the damper whilst at the other end of the bar is the coupling flange (15).
