Title: Signalling system between PBX telephone exchanges - ensures detection of signals by increasing length of first dialling pulse
Inventor: ORMONEIT KURT
IPC: H04Q1/32
Filed: 1975-07-24
Abstract: The signalling system is used to transmit messages between PBX telephone exchanges. The detection of short dial pulses is made more certain by increasing the length of the first dialling pulse by a predetermined time. This not only ensures that the first pulse is easily detected from amongst all other signalling signals especially when heavy distortion is present but also allows an extra signalling signal to be transmitted with each dialling pulse train. This extra signal transmission can be independent of the actual increase in length of the first dial pulse. The pulse correction circuitry has circuits to increase the length of the first pulse and, at the transmitter, to delay the release of the pulse train.

Title: Maleic anhydride continuous prodn. by gas phase oxidn. - using granular active carbon absorbent to recover hydrocarbon from waste gas stream
Inventor: ERPENBACH HEINZ DIPL CHEM DR
IPC: C07C51/215
Filed: 1975-10-08
Abstract: Continuous prodn. of maleic anhydride (I) comprises (i) reacting 4C hydrocarbons (II) with air in the gas phase at 250-600 degrees C on an oxidn. catalyst; (ii) washing (I) from the hot reaction gases with an aq. (I) soln., and (iii) recovering (I) by drying and vapourisation. 75-98% of the (I)-free reaction gas, contg. unreacted (II), C oxides, air and N2, is recycled after adding fresh air and (II), whilst 2-25% of the gas is discharged. The amt. of fresh air, is pref. equivalent to the consumption of atmospheric O2 or amt. of atmospheric N2 in the waste gas. The improvement comprises passing the gas to be discharged through one of 2 zones filld with active C granules for absorption of (II), pref. at 20-30 degrees C. When one zone is satd., the other is used for absorption, whilst the first is regenerated by desorption of (II) by heating to 60-140 degrees C and passing fresh air through this is in the opposite direction and then into the recycled main stream. Process reduces loss of (II). In an example, the oxidn. of a gas contg. 2.9 vol. % C4H10 (n- and iso-) over a V/P oxide catalyst and absorption of (I) gave a gas contg. 2.5% C4H10. 12% of this gas was dicharged after recovery of the C4H10. The C4H10 conversion was 14% and the (I) yield 108 kg/100 kg C4H10.

Title: Fast acting DC restoration circuit for pulse height analyser - constant current source provides rapid charging of capacitor
Inventor: OGAWA SEIJI
IPC: H04N5/18
Filed: 1976-04-28
Abstract: A clamp circuit for DC restoration and maintenance of base-line level in a circuit with a DC isolating coupling capacitor. A source (1) is connected to the output side (T2) of capacitor (C) through a switching transistor (Q). Terminal (T2) is also connected to a constant current source (2). The base of the transistor is earthed through diode (D), and fed from a constant current source (3) with a current equal to that derived from the source (2) so that base of the transistor is maintained at potential Vf. The characteristic curve of base/emitter voltage and collector current is so chosen that is closely matches that of the forwards voltage/current of the diode. In the absence of a signal at the condenser input T1, all collector current passes to the source (2) so that voltage across the diode equals the base/emitter voltage of transistor (Q), and the terminal (T2) is held at earth potential. A positive signal input to T1 back-biasses the transistor and the pulse passes to (T2) and during the period of the pulse current passes from the capacitor to current source (2). As the potential at (T1) returns to zero a high forwards bias reaches the transistor and a heavy collector current flows, rapidly charging the capacitor and restoring the potential at (T2) to zero.
