Title: Ultrasonic non-destructive testing of materials - has rigid coupling between converter and test piece
Inventor: TOMILOW BORIS WASILIEWITSCH
IPC: G01N29/28
Filed: 1974-03-29
Abstract: A rigid acoustic coupling is made between an electro-mechanical converter and the test piece by continuous pressure. The converter and the test piece are made to vibrate in common and the material for testing is irradiated with ultrasonic test signals. In the course of the test the rate of change of the test signal amplitude is monitored. When the amplitude drops abruptly, vibration is suspended and the test signal parameters which appear as data carriers for the test case are measured. The parameters of the test signal are measured, not immediately after vibration has ceased, but after an interval long enough to allow the residual stresses on the converter, caused by vibration and pressure, to disappear.

Title: Smoker's pipe scraping tool - has scraper arms extended to required position by rotating threaded spindle
Inventor: ZYSSET KARL
IPC: A24F9/10
Filed: 1974-04-22
Abstract: A smoker's pipe scraping tool has a elongated cylindrical housing with a pull-off cap one end, enclosing a set of retractable scraper blades around a hollow tube inside which slides a pointed rod, so that when a cap at the other end is rotated, the rod is forced downwards until its pointed end is pushed against a protuberance on the back edge of each blade so that the blades are swung outwards. This controlled movement of the actuator rod, which is moved by the cap, which is carried by a screw threaded portion inside the housing, enables the blades to be set so that an excess amount will not be scraped from the inside of the bowl of the pipe.

Title: Numerical data signal transmission via coupling device - improved method of transmitting data
Inventor: WINTZER KLAUS
IPC: H04Q11/04
Filed: 1975-04-30
Abstract: Numerical data signals can be delivered by signal transmitters in any time succession simultaneously with a preceding address signal which indicates a determined signal receiver for the reception of the data signals, via a coupling device. The data signals of the different signal transmitters considered are separately memorised for each signal transmitter, before being routed to the coupling device. Only when in the present of a determined number of data signals coming from the signal transmitters, and the data signals and the address signal characterising the desired signal receiver, sent to the coupling device. Communication between the coupling device input, at which address and data signals are introduced, and its output, which is coupled to the desired output signal, is established due to the address signal considered uniquely for the duration of data signal transmission.

Title: Procedure for spaced stacking of boards - boards are spaced on stacking place by backwards movement of running cross conveyor
Inventor: RIGHI EDUARD
IPC: B65G57/18
Filed: 1975-11-19
Abstract: The procedure is for spaced stacking of boards by which the delivered boards (2) are built up on a cross conveyor (5) to form an enclosed layer (11). Subsequently the cross conveyor (5) with the layer (11) of boards is brought in a position above the stacking place for the boards. The positioned and running conveyor is then moved backwards at a speed which is higher than its conveying speed. During the backwards movement of the conveyor the boards are placed on the stacking place in such a way that they are spaced on the stacking place in such a way that they are spaced a distance (S) apart. The speed difference between the backwards speed and the conveying speed of the conveyor (5) is adjustable. The conveyor (5) which has a small height (L) is movable from a position at the side of the stacking place to a position above the stacking place.

Title: Steam whistle noise simulator for model railways - has monostable multivibrator, operated by tripping contact, modulating sinusoidal voltage generated by oscillator
Inventor: MASSOTH HARTMUT
IPC: G10K15/02
Filed: 1975-11-22
Abstract: The steam whistle noise simulator is for electrical model railways. It has a sinusoidal voltage generating oscillator and a multivibrator, operated by a tripping contact, to modulate the sinusoidal voltage. The monostable multivibrator smoothly switches the drive voltage for the oscillator on and off via a RC unit. This gradual operation produces a more natural sounding effect. The signal produced by the sinusoidal generator has its amplitude or frequency modulated by the voltage of a noise generator (2). The result is fed to the loudspeaker via an amplifier. Operation of the tripping contact (S) causes the generator to be switched on via the monostable multivibrators (T1, T2) and after about two seconds to be switched off again.
