Patent DE-2547231-A1 (DE)
Title: Furnace winder for Steckel rolling mill - has split thrust ring with axial gap on cooled shaft
Inventor: SEIBEL ARTUR
IPC: B21C47/26
Filed: 1975-10-22
Abstract: The components of the winder are built on a cooled shaft and clamped together by a spring. Divided thrust rings are fitted between the springs and the winder shield, made from materials with different thermal conductivities. The thrust rings ensures axial mobility of the thrust ring system in case of breakdowns for elasticity of the winder clamping. The inner ring on the shaft is made from material with good thermal conductivity. This ring is divided into at least two separate stepped rings (13, 14) with axial and radial gaps. These separate rings are in contact on radial gaps. However, a slight axial separating gap is ensured between axial surfaces. The individual rings have an L-cross section. The contact faces (17, 18) on the shaft (11) and on the outside rings (12) cover the whole width of the divided inside ring.

Title: Pneumatic control circuit for rubber shoe injection moulder - allows closing of mould to be interrupted in emergency
IPC: B29C45/67
Filed: 1975-11-03
Abstract: A control unit for a cylinder and piston arrangement opening and closing the mould of a synthetic or natural rubber injection moulder, esp. a machine for casting the sole and heel on to a shoe upper, includes a membrane type directional valve which, in each of its two positions connects one chamber of the cylinder to a compressed air supply and vents the other to atmos. One operating side of the directional valve is connected via a pilot line to a compressed air supply and to a switching circuit which in turn is linked to the other operating side of the directional valve. In the switching circuit there is a spring-loaded manually operated shut-off valve, which, in its normally open position allows air to flow from supply and position the directional valve so that the mould is open, whilst when it tripped over by hand so as to vent the switching circuit, the directional valve is allowed to move over and close the mould. The control circuit practically rules out the possibility of injury to the operator by the closing of the mould. When the manually operated valve is released, the mould opens automatically.

Title: Solar radiation collecting water heater - has water flowing between upper and lower sheets of glass cover
Inventor: JUSTI EDUARD W PROF DR PHIL
IPC: F24J2/04
Filed: 1975-12-01
Abstract: The solar heater has a black absorbing plate (1) through which a pipe coil (2) runs. This carries the water to be heated. the plate with the coil is fixed across the centre of a rectangular casing. The space between the plate and the sides and bottom of the casing is filled with insulating material (4). The top of the casing is covered by a double glazed plate with a gap between the upper and lower sheets (6a, 6b). The water to be heated flows through this g ap before entering the absorber plate coil (2). The water thus takes up the portion of the solar radiation absorbed in the glass.

Title: Vacuum cleaner upholstery nozzle with no thread blockage - has channels extending up to either side of suction pipe opening
Inventor: LEKUSE EDUARD DIPL ING
IPC: A47L9/02
Filed: 1976-01-27
Abstract: The upholstery nozzle is in the opening with two longitudinally parallel walls which form a channel which extends over the entire height of the nozzle, is separated from the suction chamber of the nozzle and is divided into two partial channels (3,4) which extend from the lateral nozzle edge only up to the edges (9,10) on either side of the mouthpiece of the nozzle pipe (2). The channel walls (5,6,7,8) need not extend right up to the plane of the nozzle edge but a slight gap (11) can remain between these walls and the surface to be cleaned. In this case a longitudinal web (12) can be mounted in the centre of each channel which extends up to the surface to be cleaned so that when cleaning lightweight fabrics they themselves are not drawn against the walls.

Title: Method of fixing blades to axial-flow turbine rotors - peripheral lacing wire secures interlocking blades positively, root shoulder is peened over
Inventor: WIKSTROEM ROLF DIPL ING
IPC: F01D5/30
Filed: 1976-02-20
Abstract: To supplement the normal anchorage of the blades (3) in the rotor rim (2), the blade root shoulders (5) have grooves cut in them runnin peripherally on both sides continuous wire (9) is laid into these grooves and held there by rolling in the outer lip. To secure the blades even more firmly, the rotor rim (2) corners can be chamfered and the root shoulder peened over. The wire (9) can also be used to secure a peripheral sealing strip. In addition to holding the blades axially and damping axial vibrations, the wires carry centrifugal loads and shorten the effective blade length, which lowers various blade root stresses.

Title: Tufted carpet carrier material - coated with a heat-activated adhesive to bond pile knots for long life
Inventor: KEHR HELMUT DIPL CHEM DR
IPC: D05C17/02
Filed: 1976-03-11
