Title: Catalytic reactor with recycling induced by jet - has catalyst in outer annular chamber to improve recycling ratio
Inventor: LUFT GERHARD PROF DR ING
IPC: B01J8/02
Filed: 1978-02-27
Abstract: A circulation reactor has a jet drive for circulating the contents and promoting chemical reactions. The catalyst or other solid required for chemical conversions or adsorption processes are contained in the outer annular space of the reactor. Circulation is promoted by the jet causing downward flow in the central pipe and upward flow through the annular space contg. the catalyst. The recycling ratio (i.e. ratio of recycled to new flow) can be considerably increased for a given reactor. The dia. ratio of the outer to the inner pipe is pref. 2:1-5:1 (esp. 3:1-4:1).

Title: PBX call transfer system - uses centrally controlled timer and corresp. storage facility to initiate busy-free check on subscriber stations
Inventor: FEY DIETER DIPL ING
IPC: H04M3/46
Filed: 1978-08-30
Abstract: The call transfer system uses an existing central control unit and its storage capability to avoid losing a call first made unsuccessfully to a subscriber station. If the called station does not answer within a certain time limit, this call is transferred to a further station associated with the first non-answering one. A timing unit initiates a check on the next possible available station. If the station is occupied or does not answer, the timing cycle continues and the call is transferred back to the subscriber station originally called to check if it is now free. If the alternative station is free the timing cycle is stopped, the calling party is connected to the station now free and the station originally called is released.

Title: Oxidn. of reduced vat or sulphur dyes - with alkali-metal chlorite(s) in presence of chelating agents
Inventor: BALLAND JEAN
IPC: D06P1/22
Filed: 1978-11-30
Abstract: Dyeings produced by the application of the reduced forms of vat or sulpur-dyes are oxidised by alkali metal chlorites, e.g. Na chloride in acid medium, to which chelating agents have been added. Oxidn. of vat or sulphur dyes is usually carried out with alkali peroxides, oxygenated water or alkali dichromates. The first two tend to lead to 'suroxidn.' with certain sulphur dyes, and dichromates often cau se dulling of shades, as well as causing pollution. No such problems arises with chlorites but they must normally be applied at a relatively alkaline pH and high temp. than normal (>80 degrees C). It has now be found that they can be applied at acid pH if chelating agents are added to the bath, they do not affect the tinctorial character of the oxidised dyeings.

Title: Thyristor inverter short circuit current compensating system - increases short circuit and commutating currents to operate mains protection device
Inventor: CLEWING MICHAEL DR ING
IPC: H02M7/12
Filed: 1979-03-21
Abstract: The short-circuit current compensating system for a thyristor inverter circuit, controls the commutation in accordance with loading by electronically varying the short circuit current flow time of the thyristors. During normal operation, a commutation flow and a lower value short circuit flow corresp to a nominal value are maintained while the quenching capacitors are maintained at a high commutating voltage. In the event of a short circuit, the commutating flow of the inverter is increased to a given high value and the short circuit flow is raised to a higher nominal value to operate the protection device. The system uses a short circuit nominal value signal emitter interconnected with a control pulse emitter with commutating and short circuit flow regulators, and a timing unit giving a delay signal for the higher nominal value.

Title: Data integrity maintenance in transmission system - by winding optical fibres round cable, each terminated by reflector, and measuring time delay of light pulses through them
Inventor: SEPP GUNTHER DR
IPC: H04B3/46
Filed: 1979-08-03
Abstract: The integrity of a signal transmission line (1) e.g. a co-axial cable, is monitored by optical fibres (3.1,3.2) wound round it to form a narrow mesh embedded in the outer sheath (2) along its whole length. Each fibre is terminated at one end by a reflector. Pulses of light, preferably not in the visible spectrum, are coupled in to the other end and the time delay before return of the reflected pulse is measured. Attempts to gain access to the line damage a fibre. This is detected by change of time delay, without revealing that the attempt has been detected. The position of access is given by the new time delay.

Title: Hands-free facility for several telephones on one line - has common amplifier and interlock to prevent more than one person from using line
Inventor: BOPP FRIEDEL
IPC: H04M9/02
Filed: 1979-10-17
Abstract: The telephone system allows any one of a number of subscribers to have access to a common line. A 'hands free' facility is added by providing each subscriber with an additional microphone. An additional contact in each subscriber's access unit connects the microphone to the input of an amplifier, whose output is connected to the line. The amplifier is switched on when any subscriber lifts his receiver. The access units are interlocked by logic gates to ensure that only one subscriber at a time can be connected to the line. If one is using the line and a second lifts his receiver, both are disconnected. An auxiliary unit has a set of logic gates which recognise that two receivers are off-hook, and hence have been disconnected, and connects a dummy across the line to hold the call. It also switches a resistor across the amplifier input.
