Patent DE-2137151-A1 (DE)
Title: Synthesis gas generation - by partial oxidn of hydrocarbon liquids
Inventor: SLATER WILLIAM LEON
IPC: C01B3/50
Filed: 1971-07-24
Abstract: Synthesis gas (CO + H2) is made by non-catalytic process comprising partial oxidn. of liquid hydrocarbon fuels with oxygen-rich gas and steam. Process is economic in that steam generation is by cooling of effluent streams and hydrocarbon feed is used as a first scrubbing agent. Also, any oil loss in a second stage water scrubbing is recovered, and removal of carbon from quench water as in prior art processes is not required. Reaction is carried out in unpacked reactor at 1800-3000 degrees F. The effluent is first cooled to 400-550 degrees F (above dew point of water) by indirect heat exchange, and then scrubbed with 1-10 gals hydrocarbon fluid per 1000 cu. ft. gas (where fluid is fresh liquid hydrocarbon fuel) at temps. above the dew point of water in effluent gas to remove particulate carbon, followed by recycle of the fluid-carbon slurry as feedstock for the process. Also the effluent may be further scrubbed with water (1-10 gals/1000 cu. ft) at 100-500 degrees F to condense any hydrocarbon vapours, the liquid prod. then being heated and fed to the reaction zone. All process stages are operated at about equal press. in range 100-3000 psig.

Title: Extruded semi-finished prod. encapsulation
IPC: B27N7/00
Filed: 1972-09-19
Abstract: Tube consisting of a metal core tube and a thermoplastic resin cover, esp. an underground pipe, is produced by (a) providing the surface of the core tube with a layer of glue, (b) applying the cover in the form of a seamless hose, or spirally wound strip by extrusion, and (c) transporting the tube on a transporter through a cooling zone by alternately supporting and then releasing successive portion of the tube by the transporter.

Title: Time measurement system for telephone operation - auxiliary electronic cct. provides accurate measure of length of calls
Inventor: MIERICKE DETLEV
IPC: H04M15/10
Filed: 1974-03-08
Abstract: The selection circuits of a telephone system are activated when an outgoing calls is made and a relay is switched during the connection period. A potential is applied to a sensing circuit. Since the telephone transmission system operates at 60V the level must be reduced in the sensing circuitry to 12V for utilisation in the control circuitry used to monitor the time period of connection. In particular the control circuitry contains a timing unit to measure the longest interval that a connection is made. Facilities are included to terminate the duration measurement process dependent upon whether the call is terminated by the subscriber or by the receiver.
Patent DE-2411889-A1 (DE)
Title: Automatic regulating circuit for controlled rectifier - which compensates errors produced by discontinuous output current has variable loop gain
Inventor: BOEHM KLAUS DIPL ING
IPC: H02P7/293
Filed: 1974-03-12
Abstract: The regulating apparatus is used in the automatic control of the output of a thyristor rectifier in such circuits where the controlled current may become discontinuous, due to the combined effect of delayed thyristor firing and the time constant of the load. The discontinuities in current affect the regulator performance. Where the regulator is controlled by the reference value plus a correction signal the current discontinuity effect is compensated for by changing the loop gain during the gaps in current flow by the amount required to maintain performance. A proportionality element is introduced into the control loop for this purpose.

Title: Thermocouple with chromium di-silicide positive limb - and metal negativeeevel limb, for very sensitive flame detectors
Inventor: AIHARA KEIJI
IPC: G01K7/02
Filed: 1974-12-11
Abstract: Thermocouple with a positive limb of CrSi2 and a negative limb of metal pref. constantan or alumel, is used as a very sensitive flame detector. The thermoelectric voltage is much greater than (at least double) that of conventional thermocouples, e.g. of chromel-constantan or chromel alumel. CrSi2 also has much better resistance to heat and corrosion than materials normally used for the positive limb. It can be at temps. up to 500-700 degrees C, so that temp. differences of 400-600 degrees C between the 2 limbs can be produced.
