Title: Sound transducer for acoustic surface waves - consists of two electrodes with metal fingers on piezoelectric substrate
Inventor: HAYDL WILLIAM DR ING DR
IPC: H03H9/145
Filed: 1974-07-02
Abstract: A given transmission curve of a filter is achieved by converting the intensity of the acoustic surface waves excited from the individual transducer electrodes. Resistors are connected in series with individual fingers of one or both electrodes. The achieved advantage of the invention is that a new transmission characteristic of the filter is maintained while keeping the width of the overlapping fingers constant. Acoustic surface waves are sent out via a constant aperture (8). The single electrodes are switched in parallel through series-connected resistors (10) having values calculated to satisfy a given function (11). The thin film resistors (10) are preferably formed by placing on the metal layer of the electrode at the required length for the desired resistance. The electrode metal is then removed by chemical etching.

Title: Electrolytic refining of lead contg. bismuth - initial high cell current gives large increase in productivity
Inventor: KRAUSS CLIFFORD J
IPC: C25C1/18
Filed: 1974-10-31
Abstract: Multiple cells are used with lead anodes and cathodes and contg. an electrolyte of lead fluorosilicate and fluorosilicic acid. The novelty is that the anode voltage is maintained below the value at which Bi starts to dissolve from the anode, using a controlled redn. in the current passing through the cells. It is pref. to maintain the anode voltage only just below the critical value, i.e. the point where Bi starts to dissolve. At the start of the process, i.e. with a new anode, the anode voltage is low so the current can be greatly increased and is then gradually dropped as the mud on the anode causes a rise in anode voltage.

Title: Hollow thermoplastic products with internally opening grooves - inject and blow mould design ensures constant wall thickness
Inventor: SCHREIER PETER
IPC: B29C49/06
Filed: 1975-01-31
Abstract: Hollow objects of synthetic thermoplastic material are produced by injection/blow moulding with an inwardly opening groove forming a projection on their outer surfaces. After injection and the cooling off of the material to a point at which it can still be deformed, a first plunger sleeve retracts axially to leave a cavity of the width and height of the circumferential groove. This motion generates the axial displacement in the opposite direction a second plunger against the outer face of the plastic container, and simultaneously admits the medium for expanding the vessel wall into the moulding groove. The circumference of the moulding arbor, at each side of the ports for the pressure medium, may have recesses machine to assist in providing extra material for the groove wall. Forms a circular rib, opening internally, without any weakening of the wall thickness. The forced reinforcement ensures a wall thickness in the zone of the groove at least equal to the original.
Patent DE-2506700-A1 (DE)
Title: Bending plastically deformable profiles, profiled panels or bands - by stretching beyond flow limit and simultaneously applying additional flexural torque
Inventor: WILKENING HERMANN DR
IPC: B21D5/14
Filed: 1975-02-18
Abstract: Open or closed profiles, profiled panels, bands or the like, consisting of plastically deformable material, are bent (curved) by stretching same over their entire cross-section, beyond the flow limit (yield value) whilst simultaneously applying additional flexural torque (bending moment) so as to achieve the desired curving. Generation of inherent built-in tensile stresses during the curving step is avoided. This eliminates the risk of subsequent buckling of the materials under compressive stress. The flow limit of the material is exceeded to an extent such that the material is not below its flow limit, at any point of its cross-section, having regard to the compressive stress resulting from the flexural torque applied.
