Title: A process for increasing the yield in civetone, starting from civet
IPC: C07C45/00
Filed: 1927-01-20
Abstract: 267,893. Naef, M., and Firmenich, F., (trading as Naef et Cie, M.). March 17, 1926, [Convention date]. Civetone. - The civetol contained in civet is transformed into civetone by oxidation with chromic acid or by oxygen in the presence of a silver catalyst or by catalytic dehydrogenation by the passage of the civetol at a high temperature over nickel, copper, or platinum. The civetol may be first purified by transforming it into phthalic ester. In examples, civet, from which the compounds having an unpleasant smell have been extracted with steam is boiled in an alcohol solution with alkaline hydroxide to saponify and neutralize the fatty esters and fattv acids it contains, and these are precipitated as the calcium salts. The residue is extracted with ether or benzene and the oil dissolved is distilled in a vacuum. The civetone is converted into its semicarbazone, and the civetol separated by digestion with petroleum ether and oxidized with chromic acid, or dehydrogenated by passing it over heated platinum, or in the presence of oxygen over heated silver. The civetol may be oxidized without separation of the civetone by chromic acid or by passing it over heated copper and the operation may be repeated till all the alcohol is converted.

Title: Welding machine for manufacture of wire mesh
IPC: B21F27/10
Filed: 1972-01-14
Abstract: 1312424 Welding by pressure EVG ENTWICKLUNGSUND VERWERTUNGSGESELLSCHAFT mbH 14 Jan 1972 [28 Jan 1971] 1939/72 Heading B3R In a wire mesh welding machine having several welding heads spaced across the width of the machine, each welding head having a pair of electrodes 8a, 8b, the lower electrodes 8a are vertically movable by means of a common thrust beam 30 which with its drive mechanism is disposed below the plane EE of the welded mesh, while the upper electrodes 8b are stationary, and the bus-bars 4a, 4b, 5a, 5b together with the electrical supply transformer 2, 3 are disposed above the plane EE. To provide for adjustable spacing of the longitudinal wires the welding heads, which are suspended from the bus-bars, are laterally adjustable thereon. In addition, disengageable thrust-pins 28 are provided which in the engaged position transmit pressure from the thrust beam 30 to a thrust transmitting piston and cylinder mechanism (Fig. 4) to displace the lower electrodes to the welding position. Manually controlled levers 29 can be used to move the thrust pins 28 to a disengaged position, thus rendering selected welding heads inoperative. The thrust transmitting mechanism comprises pistons 22, 23 with a cylinder space 21 therebetween which is connected to an hydraulic supply of controlled pressure. By this means the pressure of the electrode on the crossed wires during welding remains constant irrespective of the size of the wires or of the reduction in size during welding. Two different hydraulic systems of different pressures may be selectively connected to the cylinder spaces 21 of different welding heads to provide different weld pressures at different points across the width of the mesh being welded.

Title: Improvements relating to magnetic switching devices
Inventor: GOSLING JOHN CEDRIC
IPC: H01H36/00
Filed: 1963-01-01
Abstract: 1,031,782. Magnetic switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 9, 1964 [Jan. 16, 1963], No. 2018/63. Heading H2B. The object of the invention is to reduce the operating differential of a magnetic switch actuated by the movement of a flux diverting member. As shown, a sealed magnetic contact unit 3 is normally closed by a permanent magnet 4 and is opened by the insertion of a flux diverting member 5 between the unit 3 and permanent magnet 4. Opening of the contacts de-energizes a relay 9 with normally closed contacts 8 so that a coil 6 surrounding the unit is energized through a variable resistor 7 to a level just insufficient to reclose the contact unit 3. The coil 6 acts in the same sense as permanent magnet 4 so that the unit 3 is reclosed after the member 5 has been removed a shorter distance than would otherwise be necessary. In Fig. 3 (not shown) the permanent magnet is replaced by an electromagnet whose operating winding is in series with a variable resistor shunted by normally closed contacts of a delay 9. On insertion of member 5 the contact unit opens, de-energizing the relay 9 and causing its contacts to close short-circuiting the variable resistance and thereby increasing the current through the electromagnet. The contact unit therefore recloses in a shorter withdrawal distance.

Patent GB-628630-A (GB)
Title: Improvements in or relating to printing mechanism for calculating machines
IPC: G06C19/04
Filed: 1947-01-23
Abstract: 628,630. Calculating-apparatus. NILSSON, R. S. Jan. 23, 1947, No. 2122. [Class 106 (i)] The printing mechanism for a calculating- machine comprising type-bars adapted to be positioned in relation to a printing plate and a single hammer for moving the type-bars to print, includes an interposer for each order which is raised and positioned between the hammer and the type-bar when a digit other than zero is set in that order to ensure that the hammer applies sufficient pressure to effect an impression. The interposers co-operate in such a way as to raise the next interposer on the right to the operative position to ensure the printing of all zeros to the right of the first significant digit, while suppressing those to the left. Nose-pieces 23 on type sectors 6 are normally spaced away from zero stops 33 on the carriage and engage them when the corresponding sector has a zero setting, type-bars 34 being raised to bring the appropriate characters opposite a platen 36 by means of teeth 38 on the sectors. On each sector 6 there is an arcuate abutment 41 which rocks a bell-crank lever 42 about a pin 43. A carrier-plate 46 attached by a pin-and-slot connection 49, 50 to a limb 44 of each bell-crank lever has an interposer 40 integral with it and normally disposed beneath the spaces between the hammer 39 and the type bars 34, the interposer of a particular order being lifted into these spaces by operation of the abutment 41 when a digit other than zero is set in that order. The pin-and-slot connections ensure that the interposers are positioned squarely in the spaces. The movement of a sector 6 to register zero is insufficient for its abutment 41 to operate the bell-crank lever 42. The carrier plates 46 have laterally-extending wings 47, 48 (Fig. 3) so interconnected that when a carrier plate is raised to position its interposer it raises with it the next carrier plate to its right. Thus all interposers to the right of a digit setting other than zero are raised even though one or more may correspond to a sector having zero settings, so that when the hammer 39 is swung against the type bars all zeros to the right of a significant digit are printed. The hammer, a bar, is carried by end arms 51 (Fig. 2), each pivoted at 52 and each having a roller 54 operated by a cam 55. A retractor plate 57 has hooked fingers 58 which engage side flanges on the type-bars to withdraw these from the platen 36. Specifications 620,175 and 628,636 are referred to.

Numerous suitable adducts are listed. The polyaldimines or polyketimines used are those derived from diamines or polyamines and aldehydes or ketones and many suitable compounds are listed.  In general, the amount of polyaldimine or polyketimine groups present should be such that about 0.05 to 1.0 aldimine or ketimine groups are present for every isocyanate adduct group.ALSO:A process for the production of films on articles comprises applying to the articles a solution containing an aromatic polyisocyanate adduct, a compound or mixture of compounds each containing a plurality of aldimine or ketimine groups, exposing the article to the action of moisture to provide water for the hydrolysis of the aldimine and/or ketimine groups and also at the same time or thereafter subjecting the article to the action of heat. Polyisocyanate adducts are the interaction products of compounds containing a plurality of isocyanate groups with hydroxyl compounds such as phenol and its homologues.  The polyisocyanate may be aromatic di- or triisocyanates and also isocyanate ended pre-polymers.  That is the further reaction products of phenol or its homologues with the reaction products of such aromatic isocyanates with compounds containing a plurality of hydroxyl groups in such proportions as to leave an excess of unreacted isocyanate groups. Examples of such prepolymers are the reaction product of excess of a polyisocyanate with a glycol, polyesteramide or polyether.  Part of the polyaldimine or polyketimine may be replaced by a hydroxyl-ended polyether or an aliphatic polyol.  The adduct may be dissolved in a solvent and the polyaldimine or polyketimine and the solution applied by brushing, dipping or spraying and the coating dried in moist air at up to 50 DEG C.  The coated article is then cured by heating at up 200 DEG C or higher.  The substrate may be rubber, paper, wood, leather, metals, glass, plastics such as polyvinyl chloride and textiles of artificial or synthetic fibres. Pigments, oil-soluble dyestuffs, plasticiser, light stabilisers, antioxidants and/or antistatic agents may be present.
