Title: Method for preparation of ª-(5-nitrofuryl-2)acrolein
Inventor: VENTER KARL KARLOVICH
Filed: 1965-11-12
Abstract: Preparation of b -(5-nitrofuryl-2)-acrolein by hydrolysing 5-nitrofurfural diacetate in the presence of mineral acid and then condensing the 5-nitrofurfural thus obtained with acetaldehyde in an organic solvent and in the presence of a salt of an organic acid and a secondary amine.  The hydrolysis of 5-nitrofurfural diacetate is preferably carried out by heating to 90 DEG  to 95 DEG  C. for 10 to 20 minutes with stirring, the 5-nitrofurfural is extracted with the organic solvent, e.g. benzene, used in the condensation stage and the extract is washed with water or an aqueous solution of an inert mineral salt.  The preferred condensation catalysts are the acetates of morpholine or diethylamine which may be prepared in situ in the organic solvent extract containing the 5-nitrofurfural starting material.

Abstract: 1,190,257. Oxidation of alcohols to aldehydes and ketones. UPJOHN CO. 23 Oct., 1967 [16 Nov., 1966], No. 48108/67. Headings C2C and C2U. Primary and secondary alcohols are oxidized to the corresponding aldehydes and ketones by reaction with liquid hydrocarbon sulphoxides and sulphur trioxide, or complexes containing it, in the presence of tertiary amines. Substantially anhydrous conditions are preferably used. A preferred sulphur trioxide complex is that with pyridine, a preferred sulphoxide is dimethyl sulphoxide and preferred tertiary amines are alkylamines such as triethylamine. The process is particularly applicable to steroidal alcohols, and also more generally to allylic alcohols, steroidal or otherwise. It may particularly be employed to oxidize selectively a 20-hydroxy group in an 11#,20-dihydroxy steroid, the 11#-hydroxy group remaining unoxidized due to steric hindrance.

Abstract: 1485790 Ionization and semi-conductor smoke detectors NOHMI BOSAI KOGYO CO Ltd 8 Nov 1974 [9 Nov 1973 29 May 1974] 48505/74 Heading G1N [Also in Division G4] A fire alarm comprises two sensors, differently responsive to at least one phenomenon accompanying combustion and giving a progressive change in output signal in response to said phenomenon and a common evaluating circuit arranged so that an alarm signal is only given when the sum of changes in the output signals of the two sensors exceeds a predetermined level. In Fig. 3 one sensor is a semi-conductor CO sensitive device 90 having a heater 93 and a further electrode 92. The further sensor takes the form of a photo-electric smoke detector 12, 13. After amplification at 95, 72, 11, 76 the signals from the two sensors are combined at the collectors of transistors 72, 76 so that each tends to reduce the sensitivity of Zener diode 80. In the combined presence of adequate signals from both sensors, Zener diode 80 breaks down, so that transistor 81 turns on thyristor 7 and energizes the alarm relay 41. In Fig. 1 (not shown) a pair of ionization chambers are coupled to a FET connected in series with a junction transistor supplied with signals from a photo-electric detector. The combined outputs from the FET and junction transistor break down a Zener diode which turns on a transistor which triggers thyristor 7.

Abstract: 1399538 Co-ordinate data processing systems INTERNATIONAL BUSINESS MACHINES CORP 2 Nov 1972 [30 Dec 1971] 50458/72 Heading G1N A method of encoding the co-ordinates of points on a three dimensional object such as a manikin comprises sensing the position of points on the object for each of two different orientations of the object, storing the positional information in a data processing system, deriving the three dimensional space co-ordinates of the points and storing the co-ordinates. The manikin is supported by a member 68 above a capacitive tablet 62 and each of fifteen points on the manikin is sensed in turn by a probe 64 to enable a controller 66 to supply to a computer the co-ordinate data of each point projected into the plane of the tablet. The computer calculates the direction cosines of the manikin limbs and an isometric projection of the manikin which is displayed on a device 60 along with a pose number and a point number (i.e. one to fifteen). By determining the co-ordinate data of the manikin for several poses and by rotating the manikin through 90 degrees a sequence of images may be displayed to provide, for example an animation sequence of cartoon character poses. By linear interpolation the computer is also able to calculate isometric projections of poses intermediate the sensed poses. The system enables erroneously encoded points to be erased and reencoded and is also applicable to the three dimensional analysis of models of, for example, aircraft equipment, weaving machines, wire wrapping machines, earth moving equipment, &c. Instead of using a capacitive tablet, wires which terminate at each of the 15 points may be sequentially energized via a motor driven selector switch. The co-ordinate data may be stored on magnetic tape or recorded on cards for later reference or use by other computers.
