Title: Catalytic syntheses with high yields - suitable for mfg. ammonia, methane, methanol, or the conversion of carbon monoxide
Inventor: HARDWICK WILLIAM ESWARD
IPC: B01J8/00
Filed: 1977-02-11
Abstract: A reversible, exothermic, gas-phase reaction is undertaken where a gas stream contg. one or more reactants is fed through >=1 catalyst zones to obtain >=1 prods. The gas stream is fed at temp. (T1) into a first reaction zone (R1) using adiabatic conditions so as higher temp. (T2) is attained; T2 is lower than the inactivation temp. of the catalyst. The gas at T2 then flows into a second zone (R2) provided with continuous external cooling to obtain a prod. mixt. leaving zone (R2) at temp. (T3) which is lower than T2. The gas may be recycled through the process and T3 is pref. max. T1. The initial gas is pref. a mixt. of (a) N2 and H2 for mfg. NH3; or (b) H2 and CO for mfg. methanol; or (c) COx and H2 for mfg. methane; or (d) H2 and CO, and using a CO conversion catalyst. Improved yields in the synthesis of cpds. such as CH3 OH or NH3 are obtd. For example, the % of NH3 in the outlet gas can be raised to 20% c.f. 16.5-17.5% obtd. in conventional processes.

Title: Accurate dosing of flowable solids or liquids - with computer correction of weighing errors, esp. when preparing mixts. for concrete or asphalt
Inventor: REIBER PETER ING GRAD
IPC: G01G13/12
Filed: 1978-03-13
Abstract: Shortly before reaching the desired value(S) of each dose, the feeding appts. is stopped at an actual wt. (Z) less than wt.(S). During the feeding pause, the measuring error(N) is determind, and then feeding is re-commenced, but is switched off at a point S - N to allow for the error(N) so an accurate dosed wt. (S) is obtd. In the pref. process, error(N) is calculated by a computer and used to produce a signal which switches off the feeder before point(S) is reached. The values(N) may also be stored in a memory device and used to correct each dose of material employed to make a mixt. or fill a container. The feeding rate may be reduced during the second phase, i.e. when adding wt. (S - Z); and Z is pref. 85-95% S. Used esp. in the prepn. of mixts., e.g. for asphalt or concrete; filling sacks with solids; or filling containers with liqs.

Patent DE-2824001-A1 (DE)
IPC: A47C19/00
Filed: 1978-06-01
Abstract: A board-like support (2) for the user is mounted in a frame (1) so as to be pivotable about a horizontal axle (5). A catch device (4, 6, 9, 10) allows stepwise fixing of the inclination position of the support (2).
