Title: Support panel construction for loudspeaker - has damping joint connecting it to front frame of box to prevent box vibrating
Inventor: HOLSCHER FRITZ
IPC: H04R1/28
Filed: 1977-04-07
Abstract: The support panel construction is for a loudspeaker system. It has a damping joint which connects it to the frame at the front of the loudspeaker box. The damping joint prevents sound waves from propagating from the panel to the rest of the box via the material of the box and thereby avoids the formation of resonance nodes. At high power the resonance nodes can cause the vibrations of teh box to colour the sound being reproduced. Suppression of the nodes enhances the quality of sound reproduction.

Title: Heating wall for coke ovens - allows vertical positioning of flow port adjoining vertical flues in pairs without changing clear opening area
Inventor: MINASOV ALEKSANDR NIKOLAEVITSC
IPC: C10B5/02
Filed: 1978-03-10
Abstract: A heating wall for a horizontal chamber coke oven has vertical heating flues arranged in pairs. Each pair are sepd. by a partition with a flow port in its upper portion. The flow port has slot-like guides for movably mounting a slide gate and allows the introduction of a hook to displace the slide gate in order to regulate the temp. within the upper portion of the wall. Lateral sides of the slide gate have projections inserted into guides which extend vertically along the vertical walls of the flow port. The upper portion of each guide has a stepped recess, the vertical extend of which exceeds the length of the slide gate projections. The centre of gravity of the slide gate is shifted relative to the longitudinal axis of the projections in a direction opposite to the stepped recesses for the gate to be swung and held by gravity in its uppermost position to change the vertical position of the flow port without changing its clear opening area.

Title: Ultrasonic non-destructive testing head - has composite piezo electric converter decoupled for independent variation reducing side lobes
Inventor: GEBHARDT WOLFGANG DIPL PHYS DR
IPC: G01N29/24
Filed: 1979-01-13
Abstract: A test head uses ultrasonic signals, transmitted via a piezoelectric transducer, which is fitted with attenuators, into the tested material. The transducer consists of several decoupled transducer elements, in order to reduce the level of the side lobes. The amplitudes of the decoupled transducers can be varied independently. The amplitude excitation is such that the acoustic signal is at a maximum at the centre of the transducer arrangement. Each transducer may be excited in a different phase, so as to control the main lobe. The transmitting and receiving section of the transducer may be separated by diodes. The receiver arrangement may provide central amplification, or peripheral attenuation, of the signals.

Title: compensation circuit for temp. drift - regulates zero point of magnetic field detector by using two different resistors to produce compensating voltage
Inventor: CUNO HANS-HELLMUTH DR
IPC: G01R17/00
Filed: 1979-03-08
Abstract: The compensation circuit has two different resistors providing the compensation and chosen such that the voltage drop across them in the rest state and their input resistance are suitable for compensating temp. characteristics and zero-point drift. The voltage assumed by the two resistors is the voltage at the point of intersection between the output characteristics in the hot and in the cold state of the detector. If the detector consists of two sensors (R3, R4) coupled in series with their connection linked to a load of zero input resistance then an additional resistor is coupled in parallel with one sensor to compensate zero-point drift. A compensation resistor has an appropriately increased resistance so that compensation does not adversely affect slope.

Patent DE-2920353-A1 (DE)
Inventor: BRAUN ALBERT
IPC: C21C1/02
Filed: 1979-05-19
Abstract: The invention relates to the production of an agent for desulfurizing crude iron and steel melts, the desulfurizing agent being based on calcium carbide containing calcium oxide. To this end, a calcium carbide/calcium oxide/starting melt mixture with a CaO-content within the range 20 to 80 weight % is produced from lime and coke and allowed to solidify to a block. While the solidified block still has an average temperature of more than 400 DEG  C., it is crushed to particulate material with a size of less than 150 mm. Next, the hot crushed material of at least 400 DEG  C. is admixed with a quantity of calcium oxide necessary to have in the resulting mixture an overall content of CaO corresponding to that desired for the final product. The whole is thoroughly mixed and crushed with exclusion of moisture at temperatures higher than 100 DEG  C. to particulate material with a size of less than 10 millimeters.
