Title: Load cell with surface acoustic wave resonator - has Y-cut quartz crystal substrate stressed by loading forces and bearing sets of aluminium reflective grids
Inventor: DIAS FLEMING J
IPC: G01D5/48
Filed: 1977-12-08
Abstract: The load cell using surface-acoustic-wave principles consists of a Y-cut quartz crystal substrate (10) at the ends of which are sets of aluminium reflective grids formed by plasma beam etching and metallisation (12). Between the sets of grids is a transformer (14) formed from interlocking comb patterns by thin-film techniques. The whole forms a surface-acoustic-wave resonator. An oscillator (16) is connected to the resonator. The substrate is supported on a rigid element forming the loading beam of a load cell. When the beam is flexed, the oscillator frequency falls or rises, depending on the direction of force applied to the unsupported end of the beam, in the order of 55 Hz/gm in a linear fashion. With resonators on either surface of a quartz plate, a differential pressure/force transducer may be constructed.

Title: Screwdriver with screw retaining tip - has two resilient blades in holder in V=shape when unstressed by sliding bush
Inventor: SCHMIDT ALFRED
IPC: B25B23/10
Filed: 1978-04-13
Abstract: The screwdriver allows placing of slotted head screws in difficult access or remote areas. The handle of the screwdriver has a shank on which the double-bladed tip (1) is permanently fixed.

Title: Lid for large rubbish bin - has spring loaded air damped piston-cylinder to retard closing movement
Inventor: HUSMANN GERHARD
IPC: B65F1/16
Filed: 1978-04-29
Abstract: A swing lid (3) is hinged (2) at the rear of the bin opening (8) and is restricted by a spring loaded air damped cylinder and piston (5, 4). These allow the lid to close slowly to avoid trapping the hands. When the container is to be emptied, the frame (6) is lifted out, thus allowing the lid together with the damping device attached to be swung back clear of the opening. After emptying the bin is dropped back into place for reuse.

Title: Signal processor multiplexed pulse width modulated signals - uses limiting circuit to reduce cross-talk and non-linearity
Inventor: CZERNY HERIBERT ING GRAD
IPC: A61B5/03
Filed: 1978-06-16
Abstract: The signal processor is designed to reduce cross-talk and non-linearity when handling pulse-width-modulated, multiplexed signals. This is achieved by limiting in which the pulse width is limited to a value which is less than the clock pulse interval. A capacitor (22) is charged and discharged via a controlled switch (24). The output voltage is applied to a comparator (26) whose second input is fed from the output of the multiplexer (16) via a switch (46). This switch is controlled by a monostable (42) forming part of the limiting circuit and which is triggered after each clock pulse (A) and resets before the next clock pulse. The monostable is driven by another monostable (38) whose pulse sets the output bistable (44) of the modulator.

Title: Hydrofoil surfaces for high performance boat - fit on either side of front of hull and are contoured into hull shape
Inventor: MUELLER ECKHARDT
IPC: B63C13/00
Filed: 1978-07-28
Abstract: The modified hull shape for the performance boat has elastic mounted trim flaps (6) set under the front of the hull where some hulls are slightly concave. The flaps lift the front of the hull out of the water at lower speeds to enable it to ride on these and the rear trim flaps. The damping between the trim flaps and the hull consists of simple elastic pads. The craft planes at a lower speed so that a considerable fuel sving is obtained as well as high performance.

Title: Mfr. of axle housings by extrusion - has half axle housing extruded in stages giving better grain flow and reduces amount of welding
Inventor: SCHLICHTING JOSEF DIPL ING
IPC: B21K1/26
Filed: 1979-02-13
Abstract: The axle housing for a road vehicle is made from two identical extrusions joined by a single weld. Each half axle housing is extruded in several stages from a circular blank (1). In the first stage a punch (3), together with a suitably shaped die (2), forms a radial flange (11) and back extrudes some of the material to form a tubular extension. The semi-finished part is then further extruded to form a stepped tube. This method of construction ensures an uninterrupted grain flow in the material and reduces the amount of welding.
Patent DE-2917351-A1 (DE)
Title: Electronic organ with vibrato produced by frequency generator - has control signal produced by envelope modulator which forms decaying amplitude curve for selected tones
Inventor: BOEHM RAINER DR
IPC: G10H1/043
Filed: 1979-04-28
Abstract: The electronic organ has a switch to switch through selected tones with the aid of the keyboard. An envelope modulator forms a decaying amplitude curve for the selected tones. The time constant of the decay is defined by a control signal produced by the envelope modulator. A frequency generator produces a vibrato in which the times are amplitude or frequency modulated. The vibrato is suppressed when a key is pressed and is only reinstated by the control signal so that a new sound effect is created. The control signal controls a variable resistor which reduces the loading on the frequency generator as its resistance increases. The variable resistor may be a transistor which when fully on stops the frequency generator.
Patent DE-2917453-A1 (DE)
Title: Roller impeller extrusion press - in which slip between the roller and die is monitored to indicate blockage
Inventor: HENDERSON JOHN ANDREW
IPC: B30B11/20
Filed: 1979-04-30
Abstract: In an extruder in which material is fed into the nip between a press roll and a die having extrusion orifices, through which the material is forced, either the roll or die is positively driven causing the other of the roll or die to rotate, and slip between the roll and die is detected. When the slip, or the rate of change of slip, attains a predetermined value the feed of material to the nip is varied. Used partic. in the extrusion of animal feed pellets. Presses can easily block, choke, or flood, necessitating plant shut down to remove material from the nip, or even removal of the die to clear the orifices. By monitoring slip, conditions leading to blockage of the die can easily be detected and remedied.
