SiO2, pref. pptd. silicic acid, with particle size 3-50 m mu and surface area of about 240 m2/g; sodium silicate may also be used. Pyrolysis is in absence of moisture. (II) must be free from acids; (II) may be pre-treated with a base, or the pyrolysis catalyst may contain a solid base, e.g. 1-15 wt.% (pref. 2-10 wt.%) of alkali oxide or carbonate, esp. Na2CO3 or K2CO3. The catalyst may be prepd. by mixing 940 g. pptd. silicic acid with 1100 g. basic Cu carbonate (55.6 wt.% Cu) and 1600 g. water glass soln. (12.5 wt.% Na2SiO3), forming the mixt. into rods, drying at 120 degrees C for 16 hours and calcining at 345 degrees C for 16 hours. The gaseous (II) feed is pref. diluted with N2 to suppress resinification on the catalyst. The feed rate of II is generally 0.01-0.5 litres/litre/hour. Pdts. contain 60-85% 2-methylbutene-2 and 1-3% 3- and 2-methylbutene-1.

Title: Sugar soln concentration tester - based on gamma radiation absorption measurement
IPC: G01N23/12
Filed: 1971-11-02
Abstract: A source of energy pref. 0.1-2 MeV, esp. a Co source, radiates gamma energy through a pipe in which the soln. flows and the intensity is measured by a detector esp. a NaI cell followed by a photomultiplier and scintillation counter.

Title: Multi-channel direction finding of modulated waves - with combination amplitude, phase relationships from directed antennae voltages
Inventor: BERGANDER ARMIN DIPL ING
IPC: G01S3/14
Filed: 1974-12-11
Abstract: Multichannel direction finding uses a process of determining the incident sector or direction of one or more arbitrary modulated electromagnetic waves from amplitude or phase difference of measuring voltages derived from preferably directed antennae. To derive such amplitude and phase difference relationships the respective voltage measurements for a sender are multiplied with a reference voltage originating from the sender, or squared, being multiplied with each of the other voltage measurements. The multiplication is in one case direct, in another after preliminary phase displacement imposed on the multiplying voltage. There may be, in another mode, combination of the voltages to a summation or difference value, likewise direct and after preliminary imposed phase displacement.

Patent DE-2521698-A1 (DE)
Inventor: USHIYAMA YOSHITO
IPC: G04G5/00
Filed: 1975-05-15
Abstract: The circuit arrangement comprises an operation control circuit (7) in a time-measuring instrument, which can be switched over by an actuator which can be operated by hand and has a plurality of switch positions. The operation control circuit (7) is assigned a protective control circuit for generating during the movement of the actuator from one switch position to an adjacent one a switchover delay time which can be given a fixed setting. In this case, a delay time signal is generated which is of a prescribed length and which preferably lasts beyond the normal switching time, in order to suppress instantaneous maloperations, without in the process having to accept an unnecessarily long delay to the start of functioning of the operation control circuit. <IMAGE>
