Title: Aldehyde or ketone prodn. by alcohol dehydrogenation - with a doped zinc chromite catalyst contg. extra chromium oxide
Inventor: SOMMER OSWIN DIPL ING DR
IPC: B01J23/86
Filed: 1973-11-22
Abstract: In a process for the prodn. of aldehydes or ketones by dehydrogenation of prim. or sec. 5-15C alcohols in the presence of a Zn chromite catalyst (ZnO:Cr2O3 molar ratio=0.8-1.2:0.5-0.8) doped with 2-10 wt.% CuO and 0.5-5 wt.% CdO, an additional 5-15 (pref. 8-10) wt.% Cr2O3 is incorporated in the catalyst by adding NH4 dichromate and heating at 300-450 degrees C. Addn. of Cr2O3 increases the activity selectivity and life of the catalyst; dehydration side reactions are totally eliminated and by-product formation (aldehydes or ketones with fewer C atoms) is limited to 1.5 wt.%; conversions of 85-90% can be achieved.

Title: Conveyor belt end drum - has vaned rotor transporting material scraped from bottom run rack to top
Inventor: MAIBAUM KURT
IPC: B65G45/26
Filed: 1974-01-09
Abstract: A stripper bears against the bottom run of the belt, delivering any material on it to one or both sides once scraped off. The belt drum is coupled on the discharge side of the stripper to a coaxial vaned rotor with a conical body and radial vanes. The smaller end of the rotor body bears against the end of the drum but is of larger diameter than the latter, and it fits closely inside a stationary ring-shaped passage. This has, in the plate of the belt bottom run, a funnel-shaped inlet extending under the discharge end of the stripper, and an outlet above the top run. Material scraped off the bottom run is thus transported onto the top one, running down onto the latter via the conical face of the rotor body.

Title: Alarm system combined with perimeter fence - uses several parallel horizontal wires strung between posts and fastened to sensors
Inventor: OSTERBURG GERHARD
IPC: G08B13/12
Filed: 1974-03-21
Abstract: One or both sides of each of the wires is provided with spring means, where the wire is attached to the post and there are operating means causing the wire to be axially moved to and from. This movement of the wire is monitored e.g. by inductive circuit so that an alarm circuit is operated when the movement of the wire exceeds a given amplitude. Pref. the alarm circuit compares the wire movement with the control pulses from the operating means so operate the alarm when they disagree. Alternatively the wire movements at two points along the wire may be compared with each other.

Title: Reducing gas mixts. prodn. by gasifcn. of coal - with oxygen and minimum amounts of steam
Inventor: STAEGE HERMANN
IPC: C10J3/16
Filed: 1974-07-23
Abstract: Prodn. of reducing gas mixts. of CO and H2 is effected by gasifcn. of coal with conc. oxygen and only sufficient steam to maintain the gasifcn. temp. Used for redn. of ores in blast furnaces. Coal gasify. is carried out using established low-pressure processes. The available heat of the prod. gas is fully utilised in the redn. furnace. The blast furnace gas after processing to remove CO and CO2 is recycled, so that only enough fresh gas need is heated only sufficiently, by unprocessed blast furnace gas, to raise the reducing gas temp. to that needed in the balst furnace. Use of part of the blast furnace gas for pre-heating the reducing gas prevents the N2 content of the latter rising to an uneconomic level.
Patent DE-2437162-A1 (DE)
Title: Constant pressure regulator - has stepping motor input which applies reference pressure to a force balanced nozzle-flapper arrangement
Inventor: AKELEY LLOYD T
IPC: G05D16/06
Filed: 1974-08-01
Abstract: A pressure regulator generates an output pressure that is proportional to the number of digital signals supplied to stepping motor. Typically 200 pulses correspond to a range of 0.21 to 1.05 kg/cm2. The stepping motor output shaft varies the tension on a coil spring coupled to a froce-balance arrangement. Input pressure is applied to a differential pressure diaphragm valve and constant output pressure is bled-off to the reservoir of an expansion bellows, the free end of which operates on the force balance arm. Input flow is also bled-off to the nozzle of a flapper-nozzle arrangement. In operation the bellows and spring bias on the lever operate to provide balance against the loading applied by the stepping motor to spring. Similarly any variations in supply pressure produce an adjustment to maintain balance of the flapper nozzle.

Title: Automatic test programme within cycle of digital computer - periodic test checks output against memory for error read-out
Inventor: BIEDERMANN FRED DIPL ING
IPC: G06F11/273
Filed: 1974-09-07
Abstract: An automatic test programme is built into the cycle of operation of a digital electronic computer. The CPU consists of a main memory arithmetic unit registers and micro programme control with programme counter. The micro programme store has a section assigned for test data that is activated periodically within the cycle. When test data is applied the CPU output is transmitted to a comparison control that addresses the test memory. The data in the test memory is then compared with the CPU output. If an error exists the multiplexer is activated to generate an error display signal. If the test is satisfactory the system automatically switches back into the programmed routine.

Title: Reversing DC shunt motor control circuit - uses logic gate system to check armature control relay position
Inventor: LAUFFER HANS PROF DR ING
IPC: H02P7/03
Filed: 1974-10-07
Abstract: The application is typically to certain types of textile making machinery where a reversing motor is used to drive a thread bobbin to and for across a table, and serves to prevent the application of armature current when the reversing relays are in the process of changing over. The control input of the forward and reverse relays are also connected to the input of a logic OR-gate. The gate output is used as a control signal for the armature current generating circuits and serves to inhibit power output unless one or other of the relays is fully closed. In this way arcing at the relay contacts is prevented and relay contact life lengthened. The functioning of the armature controls is as in 2447725.
