Patent DE-2341974-A1 (DE)
Title: Bending arrangement for pipes - pipes are filled with water or liquid which can be frozen before processing
Inventor: BICHEL JOACHIM
IPC: F28D7/02
Filed: 1973-08-20
Abstract: The pipes are filled before bending with water or with some other liquid which can be frozen. The water is frozen and the bending process is carried out while the water is frozen. The ice is melted afterwards and the water is drained out of the pipe. If it is required to make helical coils of pipes around a rectangular mandrel then the pipes are wound in the first place into a circular helix. The pipe is then filled with water and this is frozen and the circular helix is deformed into a rectangular helix while the water is frozen. This process is used for making helical coils for heat exchangers which require rectangular helical pipes.

Title: Sand mould forming appts. - has core mask receiving core network from producer and transferring to mould parts
Inventor: GUNNERGAARD MARIUS
IPC: B22C9/10
Filed: 1974-06-25
Abstract: Plant for producing sand moulds with one or more cores has a machine in which mould parts are gradually produced between a pair of opposed model plates in a stationary mould chamber fixed to a guide path. The mould parts in the guide path, after parting from the model plate nearest the path, are pushed out by the other platehs transmitted motion, to be assembled to form the moulds in a row. A core mask receives the core(s) and is movable from a core-trapping position into one in front of the rearmost core part of the row, and thence axially to set the core(s) in the mould part. A core-producer with a core box with perpendicular partial surfaces is near the row of moulds, to produce a core network consisting of core(s) with attached shot strands. The axis of the core box, at 90 degrees to the partial face, is parallel to the axis of the row of moulds. The mask in its trapping position lies in the region of part of the box, and is controlled so that the network can be transferred from the core box part to the mask automatically. The mask is controlled so that its motion between the trapping and delivery positions, and in the region of the last-produced mould part of the row on the guide path, are translatory motions partially in the axial direction and partly at 90 degrees to it. The appts. is lighter, cheaper, runs faster, and needs less energy.

Each blade (1c) has a guide element (22) attached to its lower end which terminates in a guide stub (11) abutting on a central sleeve on the fan driving shaft. A thermostat which may be in the engine cooling water streams or in the stream of air leaving the radiator displaces the shaft sleeve. The guide elements have sockets which fit round a fixed shaft (23) and when the sleeve is displaced it moves the guide stubs (11) so that the guide elements (22) and with them the blades, pivot about the fixed shaft.
Patent DE-2436224-A1 (DE)
Title: Permanent magnet pulse generator with linear motion - has spring system for accelerating magnet to produce single pulse
Inventor: SUSKA CHARLES RUSSELL
IPC: H02K35/02
Filed: 1974-07-26
Abstract: The generator is used where a simple, reliable, single pulse has to be generated by an applied mechanical force, e.g. a door operating signal. In the steady state two coil springs are compressed and held by the plunger. The magnet is held against the magnetic back plate by its own attraction. Releasing the plunger allows the outer spring to expand, but the inner spring, being weaker than the magnetic attraction, remains static. At the point where the plunger flange bears against a corresponding flange fastened to the magnet, the forces of the springs add together. The magnet is pulled off the back plate, and accelerates rapidly past the coil inducing a pulse of current.
