Title: Moving strip tension regulation system - has tension detector actuating potentiometer to vary individual roller motor speeds
Inventor: HOLM WILLIAM JARVIS
IPC: B65H23/188
Filed: 1974-04-25
Abstract: A number of motor-driven rollers at intervals haul the strip along and a first variable potentiometer is connected to a part of each motor and to a power source. All first potentiometers are coupled together for simultaneous adjustment, while a second variable potentiometer is connected to another part of each motor and to a power source. A strip tension detector reacts to variations in tension and is coupled to each of the second potentiometers, varying the speed of an individual motor and its respective roller independent of the others. Each detector can have a feeler bar capable of angular movement and situated where the strip is guided or diverted. Thus when tension alters it moves in the direction of the strip and actuates the second potentiometer via a coupling.

Title: Dowel for supporting sideways load - has stepped or tapered plug to avoid high loading on wall surface
Inventor: SCHOLT EGON
IPC: F16B13/12
Filed: 1975-06-04
Abstract: When dowels are used e.g. to support a structure on a wall, the weight of the structure will exert a load parallel to the wall which will tend to be heaviest in the plane of the wall. To spread the load more evenly over the length of the dowel and to relieve the load at the opening of the hole, the outside diameter of the dowel at its end nearest the opening, is made smaller than the diameter at the other end. This is done either by tapering the dowel or by stepping down the diameter.

Title: Seismic oscillations of reactor components - measured by movements of floating mass using inductive displacement pickup
Inventor: STOELBEN HANS
IPC: G01V1/16
Filed: 1975-07-18
Abstract: A seismic oscillation pick-up, esp. for the operational monitoring of nuclear reactor components, comprises a gas-tight tubular housing containing a seismic mass, resiliently mounted at both ends and electromagnetically supported in its zero position. Conventional inductive displacement pick-ups detect deviations from this zero position. The movements of the seismic mass are pref. damped by throttling of the resultant balancing flow of gas inside the housing, particularly by means of a ring, similar to a piston ring, which surround the mass with a small gap between them. Used for detecting the oscillation behavious and loads of components, particularly in reactor plants. The apparatus does not measure an acceleration signal, thus involving difficult distinction from background noise and requiring double integration to obtain the resultant movement. Instead, it measures the actual movement of the suspended mass. The damping action of the gas can be maintained virtually constant over a wide temperature range.

Title: Rapid development of welding pressure - used on polypropylene coated containers to obtain hermetic seals between contaminated surfaces
Inventor: OLSCHEWSKI HANS-JOACHIM
IPC: B29C65/00
Filed: 1975-08-26
Abstract: Process for welding joints between thermoplastic (polypropylene) coatings on lightweight plastic coated metal containers by pressing heated surfaces together, where the mechanism for consolidating the weld interface develops the max. required welding pressure in 20 pref. 3-5% of the period required for the welding cycle. Esp. for sealing containers of >1000ml. capacity. Rapid development of the moulding pressure ensures a good weld between surfaces which are partially contaminated by material being previously put into the container, where the contamination results in nonhermetic seals if weld pressures are developed slowly. The mechanism is efficient at generating a high thrust to be sustained by the hydraulic system without requiring a high (pressure x swept volume) prod. from either of the power cylinders involved.
