Title: Method of attaching a branch pipe by welding - in which the joint is first welded from the inside
Inventor: LAUTENSCHLAEGER FRIEDRICH WILH
IPC: B23K9/028
Filed: 1974-03-29
Abstract: The method is used to weld branch pipes to other pipes or to a boiler header. A flat face is first machined round the hole to which the branch pipe is to be welded leaving a rim on this face round the hole to which a butt joint is to be made with the branch pipe. A welding electrode, preferably made from tungsten, which has a right angled bend at its end, is inserted through the branch pipe. The joint is welded without melting down the electrode by rotating the electrode and its tubular holder in the branch pipe round the seam. When this weld is completed, a second weld, during which molten material is deposited, is made around the outside of the joint.

Title: Continuous oscillation generation method - is from an irregular digital signal train whose level changes follow a rigid hase pattern
Inventor: TRISSL KARL-HEINZ DIPL PHYS
IPC: H03K5/159
Filed: 1975-02-01
Abstract: The frequency of the oscillations to be generated corresponds to the signal phase pattern. Inverting output (A1) of a digital gate (G) is fed back to its one input through a delay line (K). The irregular digital signal train is applied to the gate (G) second input (E2), and the continuous oscillation is collected from the gate other output (A2). The irregular digital signal sequence is of the return-to-zero form. An alternative form for non-return-to-zero signals uses a differentiating circuit with two OR gate elements with the output of the first passing to the second through a delay element.
Patent DE-2504521-A1 (DE)
Title: Electromagnetically operated hydraulic valve - has residual air gap to prevent magnetic locking against return spring
Inventor: REMBOLD HELMUT
IPC: F16K31/06
Filed: 1975-02-04
Abstract: Delay in the release of a solenoid valve following switch opening can result from the residual magnetic attraction between the solenoid core and the armature. This may be prevented by controlling the dimensions so as to ensure that in the energised condition, when the valve rests on its seat (10), there remains a predetermined gap between the armature and the core. Upon de-energising, rapid opening of this valve (10) and closure of the other is achieved by an excess of spring force in the armature spring (6) over that of the valve spring (12) together with the residual magnetic attraction. A brass sleeve serves as a guide.

Title: Emergency shutdown valve for reactor steam line - closes if leak occurs and partially reopens to relieve pressure build-up
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: G21D3/06
Filed: 1975-04-25
Abstract: The Parent Patent describes a nuclear reactor with a rapid shut-off valve in the steam line leading from a steam generator out through the containment shell (towards the right) to a turbine. The valve cross-section is equal to the steam line cross-section. This valve is driven by pressurised fluid to the closure position if a leak occurs in the steam line. The valve is actuated by a two-piston system, connected to the upstream side of the steam line, so that if the steam pressure rises again, the valve partially opens to less than half the flow cross-section of the steam line, to permit limited escape of steam without damage. Only one of the pistons is connected rigidly to the valve plate whereas the other piston is coupled to it only over part of the stroke. In the Patent of Addition, the latter partly coupled piston slides in the valve casing and is separated by a clearance gap, pref. of 5 mm or more, from the piston which is rigidly connected to the valve plate. The coupled piston is pref. guided in the valve casing at two positions at different axial positions, the axial distance between them being approximately equal to the piston diameter. The rigidly connected piston is pref. guided by its piston rod in the end of the casing furthest from the valve plate. The diameter of the rod is pref. 1/4 or more of that of the valve plate. Both pistons are pref. actuated through redundant valve groups. Esp. used for a pressurised water reactor. The pistons cannot jam, rendering the pressure-relieving reaction ineffective.

Title: Countercurrent heat exchanger for heat energy transport - has gas compressed to raise temp. differential for better heat transfer
Inventor: WEISS HANS
IPC: F24F12/00
Filed: 1975-09-15
Abstract: The system for transport of heat energy for utilisation at high temps. utilises gas compression for increasing temp. of a heat energy yield. Between the heat source and heat collector is a long countercurrent heat exchanger acting as carrier system for the carrier medium, usually air. In an insulated system this gives a linear temp. increase which reaches its max. at the heat collector and its min. at the heat source. Energy flow and material flow are deflected as desired by reversing the temp. differences, while pressure differences are used to reverse the temp. difference between the positive and negative energy streams. The energy is transmitted according to a pulse produced by the temperature differential between the tubes, from the negative to the positive pole of the system.
