Patent DE-2754683-A1 (DE)
Title: Shrink wrap for stack of goods - has double seamed closure bonded to outer layer during shrinking process
Inventor: BAYER MANFRED ING GRAD
IPC: B65D71/00
Filed: 1977-12-08
Abstract: The shrink sleeve (3) comprises two different layers, an outer polyethylene layer (4) and an inner polypropylene layer (5). The latter serves as a separation barrier and does not cling to the package being wrapped. The sealing closure is formed with two transverse welded seams (6, 7) separated by a short distance from one another so as to create a web (8). During the shrink-wrap process, this web, under its own weight, falls down onto the outer polyethylene (4) and becomes bonded to it. The design prevents the seal failing by splitting.

Title: Feeding tyre-beading strip onto beading core - from revolving drum with axis perpendicular to axis of support disc
Inventor: NAEDLER HEINRICH
IPC: B29C53/02
Filed: 1978-01-27
Abstract: Appts. for applying a profiled strip of vulcanisable rubber onto the beading core for the prodn. of a pneumatic tyre comprises a revolving disc on which the beading core is mounted, the dia. of the disc extending beyong the core at least as far as the width of the vulcanisable strip. A revolving drum, having its axis perpendicular to the axis of the revolving disc receives the strip in an extended straight condition and passes it onto the revolving disc; the space between the rim of the drum and face of the disc corresponds to the cross-section of the strip. The drum may either be shaped as a conical frustum in co-operation with a flat disc or as a cylindrical drum in co-operation with a shallow conical disc.

Title: Pole wheel construction for vehicle dynamo - has disc section with annular protrusion on one surface, as well as star shaped extensions, all coupled by axial bore
Inventor: MURAKAMI KINSHIRO
IPC: H02K1/24
Filed: 1978-04-19
Abstract: The rotor for a claw pole type dynamo consists of two identical and interleaving sections. Each section is produced from a cylindrical steel blank by press forming in stages. First the hub (2) is formed with a collar (3) produced by compressing the blank. In the next stages, teeth (3') are formed which are later bent over so that they lie parallel to the rotor axis to give the poles. The hub is pierced (4) for the rotor shaft. The method of production lends itself to mfr. on a series of presses, and requires only very few cutting operations.

Title: Walking beam furnace - for non-stop transition to new program by specified cycle changes
Inventor: KNAAK RUEDIGER DIPL ING DR
IPC: F27B9/20
Filed: 1978-05-10
Abstract: A walking beam furnace which heats material (alloy steel) for a rolling mill train consists of a preheating section and of a fast final heating section. On changing the average cycle time, the new workpiece spacing time and spacing in combination with the old cycle time is introduced at a moment which precedes the moment of change by the desired retention time in the fast final heating section. A position pickup determines the point at which the discharge from the furnace takes place. The fast final heating time is critical for alloy steel as regards skin decarburisation and scaling. Programme changes normally require a complete emptying of a furnace; the new system saves this and permits an uninterrupted operation.

Title: Ion exchanger for varying boron content of primary coolant - is monitored by electrical conductivity readings upstream and downstream of second ion exchanger in branch circuit
Inventor: STIEFEL MAX ING GRAD
IPC: B01J47/14
Filed: 1978-08-12
Abstract: A device for monitoring ion exchangers in a nuclear power plant in order to determine the boron content of the purified water leaving the ion exchanger, comprises two measuring points arranged in series in a branch line leading off the purified water line. Between these measuring points there is a further ion exchanger; from the different between the two readings obtained at the measuring points conclusions are drawn about the state of the process ion exchanger. A thermostat monitoring system and heat exchangers may be used to keep the measuring points at the same temp. Used in partic. for a water-cooled nuclear reactor, where the prim. coolant is treated in order to change its boron content. The method enables conventional conductivity measurements to be used to obtain an indication even of slight changes in the performance of the ion exchange system.

Title: Electrostatic precipitator with corrugated electrode plates - whose corrugations produce gas flow patterns which decelerate flow and increase dwell time of particles adjacent valleys in plates
Inventor: GELLER EDWARD W
IPC: B03C3/40
Filed: 1978-10-04
Abstract: Electrostatic precipitator comprises parallel corrugated collector electrode plates arranged so that successive crests and valleys of the corrugations of each plate are positioned opposite similar crests and valleys of the adjacent plates to form gas flow channels which successively converge and diverge. The plates have a common polarity and cooperate with an array of discharge filament electrodes of opposite common polarity located between each pair of plates. The filament electrodes are centred in and extend longitudinally through the wide regions between the opposing valleys of adjacent plates. The mean spacing between the plates is one half to one times the corrugation wavelength of the plates and the height of the corrugations between valley and crest peaks between 10% and 20% if the wave length. The corrugations produce gas flows patterns that decelerate the flow and increase the dwell-time of the particles adjacent the valleys in the plates. This maximises migration and capture of the particles on the plates without impeding the gas flow through the precipitator.

Title: Reaction tower packing element - has funnels with thin wavy walls intersecting lightweight spheres
Inventor: FILIPPETTI LENA
IPC: B01J19/30
Filed: 1979-07-17
Abstract: Packing elements for the filling of biological treatment towers are produced from plastics by injection moulding, pref. from polyolefin polymers. They have many thin wavy walls, pref. with a satinised surface, which form groups of conical funnels from the spherical outside towards a spherical cavity in the centre. Such elements are very light in weight, yet they are strong enough to withstand the pressure in a reaction tower. The presence of 96% cavities results in an excellent retention capacity for gases. The alternating acceleration and deceleration in the conical funnels achieves a good mixing efficiency.
