Title: Destruction-free testing of depth-of-hardness layers of steel - using ultrasonic transmitter and receiver to pick up transverse waves emitted at surface of specimen
Inventor: WEHNER HILMAR ING GRAD
IPC: G01N29/07
Filed: 1980-03-06
Abstract: The hardness tester consists of a transmitter (1) which is fixed obliquely to the surface of the steel specimen (2) to be tested, and emits sound impulses. The angle under which the ultrasonic impulses strike the surface of the specimen (2) amounts preferably to between 30 and 40 degrees, since the longitudinal waves are already reflected at the surface and can no longer influence the results. The considerably slower, and thus better to measure, transverse waves, penetrate the hard layer, until they strike the boundary zone between the hardened and unhardened structure, where they are reflected at the same angle and arrive back to the surface where they are picked up by the receiver (3). The results can be compared with another specimen whose hardness depth is known, and can be carried out without damage to the surface of the test specimen.

Title: Call signal generator with variable pulse characteristics - has cyclically addressed RAM storage for starting and ending ringing tones
Inventor: HAHN DIETER ING GRAD
IPC: H04M19/02
Filed: 1980-05-02
Abstract: Purely electronic switching circuits are for the selection of a telephone ringing signal at a called subscriber station from a number of alternative characteristics. It is considered desirable that a called station recognises whether a call is local or long distance, urgent business or private, etc. This is realised by the combination of a circuit common to a group of subscriber stations and a further supplementary circuit individual to each station. The former (TGr) is connected to a peripheral exchange control plant (PS) from which station selector signals (AT1 to ATn) are applied to a code converter (COD) which supplies address inputs, cyclically repeated, to a data storage circuit (RAM) which when combined with a call command (B4) stores the desired call mode in the form of a selection code as parallel data entry bits (D1 to D3). The RAM output lines (Q1 to Q3) transfer this selector code to an analogue switching array (RSEL) which switches one of several tone signal input combinations (CO, C2). The desired pulsing combination is passed to the cited second circuit group individual to each called station to produce the audio call signal selected. When the subscriber answers, a voltage appears on the corresponding individual feedback line (TM1 to TMn) for renewed data sampling. The data now being zero, the call entry is deleted.

Title: Large buoyant fender of plastics foam - produced by spirally winding foam sheet and heating facing contact surfaces to bond them
Inventor: HEINS KLAUS-JUERGEN
IPC: B63B59/02
Filed: 1980-06-10
Abstract: A method of making a cylindrical, buoyant fender or similar float of hollow cylindrical form with polyurethane stain consists of winding a sheet of polyethylene or polypropylene foam into a spiral roll, while applying a jet of hot air into the gap where the surfaces converge as the sheets wind onto the roll; this produces a temperature of 270(+-)30 deg.C at the surface and the winding speed is 80-90 cm/min, producing a stressing force of approx. 50 kp/m width of sheet, so that the surfaces are welded together. The air stream may be weaker in the central zone of the gap than at the edges. Used esp. for making modern, very large fenders for use in harbours or for floating pipelines. The method is simple and inexpensive but enables a very large hollow fender to be produced.
