Title: Production of compressed materials from acrylonitrile copolymers
Inventor: GROBE VOLKER
IPC: C08F220/44
Filed: 1966-10-13
Abstract: Compressed polymeric material is obtained by subjecting a powdered copolymer of 95-75% by weight acrylonitrile and 5-25% by weight, as internal plasticizer, of an acrylic acid ester to a pressure of at least 3000 kg./cm.2 at ambient temperature, after removal of included air.  The compressed material may then be formed thermoplastically at a temperature of at least 100 DEG  C., e.g. in air or boiling water, and can be hardened by tempering at 180-240 DEG  C.  During tempering, the polymerized acrylic acid ester is partially decomposed and gases are released which provide the polymeric material with a porous structure; simultaneously, the outer surface of the material is rendered heat- and solvent-resistant.  The compressed materials can be formed into bristles or fibres in air or a protective gas or in a liquid medium such as silicone oil.  In examples, acrylonitrile-ethyl acrylate copolymers are used.

Abstract: 1,123,215. Platen printing apparatus. TAYLOR, SMITH & TAYLOR CO. 1 Nov., 1965, No. 46048/65. Heading B6C. Dinner plates are printed in four colours whilst being carried around on an intermittently moving horizontal table 10 through platen printing stations C, D, E and F, Fig. 1. Each unprinted plate is fed from a platform 12 on to an inclined holder 11 at a feeding station A. The plate is vacuum held on the holder except for a momentary release at a centring station B and complete release at a delivery station H from whence the printed plate is removed on a conveyer 14. The station B comprises a pneumatically operated centring mechanism 50, 60 whilst the printing stations C, D, E and F are as shown in Fig. 7. The platen comprises a forme 74 detachably mounted on a reciprocable piston rod 73 forming part of a pneumatic piston and cylinder assembly 74, 73, 72 swingable by a further pneumatic piston and cylinder assembly in a vertical plane about a horizontal pivot 71. The further piston and cylinder assembly comprises parts 93, 92 and 90 which are also capable of swinging movement in the same vertical plane but about a pivot 91. Ink is supplied to the forme 74 by an intermittently rotatable horizontal inking disc 75 which only rotates when the forme 74 has withdrawn therefrom. An even ink spread is effected on the disc 75 by a stationary inclined doctor blade 80. In operation the motor-driven drive mechanism 24-27, Fig. 2, continuously rotates cams 29 and intermittently moves through a Geneva mechanism the table 10. Cams 29 actuate master cylinder piston arrangements which cause the formes 74 at the printing stations to be inked and transported to the plates currently presented at the associated holders 11. The table 10 is held or indexed at each " rest " position by a detent and ball means 128, 127 actuated by a further cam 30 driven by the mechanism 24-27 whilst release from the holders 11 of the printed plates at the station H is caused by a vertically reciprocable rod 129 moved by a cam 30A also driven from the mechanism 24-27. The printing machine also incorporates a station G which may be used for any other operation that may be necessary on the plates. The drive mechanism 24-27 incorporates an electrical circuit and contacts whereby a motor 85 for driving the inking disc 75 is actuated in proper sequence. The means for releasing the vacuum hold on the plate at the centring station B in order that the centring mechanism may operate also derives its actuation from cam and switch means associated with the drive 24-27. The centring mechanism itself is pneumatically operated through a two-way valve 36 adjacent the particular waveholder 11 in position beneath the mechanism.

Abstract: 1,160,533. Synchronizing arrangements. BROWN, BOVERI & CO. Ltd. 17 Oct., 1966 [18 Oct., 1965], No. 46285/66. Heading H2H. Synchronizing apparatus for paralleling two voltage sources U 1  and U II  comprises:-(1) a transformer and Zener diode arrangement 1.1, 1.2, 2.1, 2.2 which converts the sinusoidal voltages U I , U II  to constant amplitude rectangular waveforms U N , U G ; (2) a rectifier arrangement 3.1 for rectifying the residual voltage given by the difference U N  - U G , this rectified voltage comprising a pulse whose width depends on the phase angle (and hence on the frequency difference) between the voltages U I , U II ; (3) a capacitor 4.1 for integrating the output pulses of rectifier 3.1 and producing a voltage U c  whose rate of change depends on the pulse width and which has a minimum value corresponding to phase coincidence of the voltages U I , U II ; (4) differential relays A, B which respectively compare the voltage U c  with voltages U 1 , U 2  whose values are adjusted so that relay B is energized a predetermined time t 1  after the energization of relay A, the time t 1  thus being a measure of the frequency difference between the voltages U I , U II  as the voltage U c  falls towards its minimum value; (5) a differential relay Z having a predetermined operating time to which is compared with t 1  in order to decide whether to parallel sources U I , U II  (corresponding to a condition t 1  greater than or equal to to) or to adjust the frequency of the source U II  (corresponding to a condition t 1  less than t 0 ); (6) a differential relay E and a capacitor 8.1 interconnected by the contacts of relays A, B and Z and arranged so that when relay Z operates before relay B (t 1  greater than t 0 ) capacitor 8.1 discharges through relay E; thereby the voltage U 8  of capacitor 8.1 is compared with the voltage U c  and when these two voltages are equal the relay E is energized to cause closure of the switch for paralleling the two sources. This voltage comparison ensures that the paralleling is always effected at phase coincidence of the voltages U I , U II  since the operating time of the paralleling switch is constant and the closing command (instant of energization of relay E) is dependent on the frequency difference of the voltages U I , U II ; (7) a relay D which is energized via rectifier 19 with the difference of the voltages U I , U II  and operates at beat frequency with a holding ratio, i.e. energization voltage is greater than the deenergization voltage. The latter difference ensures that, when the frequency difference does not permit paralleling (t 1  less than t 0 ) and this frequency difference is great, a relay P or M may be operated during each beat to raise or lower the frequency of source U II  until the paralleling condition has been reached (t 1  greater than or equal to t 0 ). When t 1  is less than to relay B operates before relay Z to prevent operation of the latter and energize the relay P or M through contacts b, Z 1  and d.

Abstract: 928,011. Additions to acid electroplating solutions. DEHYDAG DEUTSCHE BYDRIERWERKE G.m.b.H. Dec. 28, 1961 [Feb. 2, 1961], No. 46401/61. Class 41. Acid baths for the production of electrolytic metal coatings contain lustring and levelling agents in the form of an organic sulphonic acid or a salt thereof which possesses at least one thiourea radical and at least one dithiocarbamic acid radical in the molecule. The invention is particularly applicable to copper and zinc electroplating baths but can also be applied to electrolytic baths which contain salts of the metals lead, tin, cadmium or mixtures thereof. The dithiocarbamic acid radical of the sulphonic acid or salt thereof has the formula where R and R 1  are hydrogen atoms or hydrocarbon radicals. Such radicals are substituted or unsubstituted cyclo-alkyl radicals or alkyl radicals which radicals together with the nitrogen atom may form a heterocyclic ring such as morpholine or piperazine ring. The thiourea radical of the sulphonic acid or salt thereof has the formula wherein R 2  or R 3  represent hydrogen atoms, or substituted or unsubstituted alkyl radicals or cycloalkyl radicals, or substituted or unsubstituted aryl radicals, or dithiocarbamic acid radicals linked via an acyclic or cyclic intermediate radical. The sulphonic acid radical of the organic sulphonic acid or salt thereof is an alkyl sulphonic acid or salt radical linked via the sulphur atom of the thiourea radical and has the formula -R 4 -SO 3 X wherein R 4  is an alkyl radical having from 1 to 4 carbon atoms and X is a hydrogen atom or a metal ion, preferably a sodium ion. As an example, sulphonic acids or their salts can be used in the acid electroplating baths in which the dithiocarbamic acid group is linked with the part of the molecule containing the thiourea and the sulphonic acid residues via an ester linkage-see compound 4 of the Complete Specification. The linkage between the dithiocarbamic acid radical and the thiourea radical is formed from a methylene radical but may also be effected by other radicals e.g. an ethylene or propylene radical or by any other short chain hydrocarbon radical which, if desired, may be substituted or interrupted by hetero-atoms or with inclusion of the two nitrogen atoms may be closed to give a heterocyclic ring e.g. piperazine. The alkyl sulphonic acid radicals are linked in the molecule via sulphur or nitrogen and are preferably introduced in the dithiocarbamic acid and/or thiourea radicals. The sulphonic acid or salts thereof are added to the electroplating baths in amounts from 50 mg. to 5 gms. per litre, preferably in amounts from 100 to 500 mg. per litre of bath liquid.
