Filed: 1970-05-22
Abstract: 1312927 Oscillating generators KOMBINAT ZENTRONIK VEB 22 May 1970 24806/70 Heading H2A A non-contacting switching device for producing electrical pulses has a permanent magnet 5, Fig. 1, mounted for rotation between the poles of a soft magnetic circuit on which is wound a coil 4, the magnet being rotatable between stops 6, 7 by projections 9, 10 on a key 8. The magnet is poled as shown in Fig. 1, and therefore has two stable positions defined by the stops. The speed of rotation of the magnet may be made largely independent of the speed of movement of the key by using the field from a second permanent magnet mounted either on the key to replace the projections, or on the same axis as magnet 5 and actuated by the projections. The movement of the magnet may be lessened by using appropriately shaped polepieces. The coil output may be used to switch on a transistor, Fig. 4 (not shown), or if it is desired to use the output from both downward and upward key motion the coil is centre-tapped and connected to a pair of transistors in pushpull, Fig. 6 (not shown). Several such devices may be used in a keyboard, to control data processing and electronic storage apparatus.

Title: Photographic production of copper images
IPC: G03C1/725
Filed: 1970-02-17
Abstract: 1316281 Photographic production of copper images AGFA-GEVAERT 19 Jan 1971 [17 Feb 1970] 7584/70 Heading G2C A photographic process comprises (1) exposing a photo-sensitive inorganic lead compoundcontaining material to activating electromagnetic radiation while the lead compound is in working contact with a reducing agent capable of promoting the formation of metallic lead in the exposed portions the lead compound yielding metallic lead on such exposure, (2) treating the obtained printout image with copper (II) ions till the metallic lead image has disappeared and (3) treating the material with a reducing agent (that is capable of separating metallic copper from an aqueous copper (II) sulphate solution) thereby producing a positive copper image together with a relatively weak negative image. Preferred lead compounds are yellow lead (II) oxide and lead (II) iodide. The lead compound is preferably dispersed in a hydrophilic water-permeable binder e.g. gelatin;lead (II) oxide may be used in admixture with an organic polyfunctional compound of which at least two chemical functional groups are OH and/or mercapto and/or primary or secondary amino groups. Many examples of such compounds are given. The lead (II) iodide or oxide may be used in admixture with a compound that possesses reducing properties and/or contains a releasable S, Se or Te atom. The reducing agent in step (I) is preferably ascorbic acid and may be present in the material or be applied by imbibition just before exposure. The material may be exposed in the wet state when the reducing agent is more active (see Ex 1 and 3). Heating the material during exposure speeds the formation of the printout image. Step (2) may be effected by treatment with an aqueous copper (II) chloride or nitrate solution. Step (3) may be effected by treatment with an aqueous sodium dithionite solution. The positive violet to blue copper image may be shielded from atmospheric oxygen and moisture by a hydropholic polymeric film, to prevent it turning to green and light yellow. Alternatively the image may be stabilised by treatment with sulphide ions or a sulphur compound containing an easily releasable sulphur atom e.g. rubeanic acid. The photo-sensitive lead compound may be applied in a removable recording layer on a waterpermeable interlayer or support into which the copper (II) ions can penetrate and after step (3) the recording layer may be removed e.g. by washing with water, leaving a positive copper image on the interlayer or support.

Rotation of the spindle results in rotation of the cam 28 and hammer 29. One end of the hammer moves into engagement with a stepped portion of the detent member 33. Further rotation of the hammer is prevented while the cam continues to rotate until a cam surface 35 and/or the torsion spring disengages the detent member 33 from hammer 29. The energy stored in the torsion spring 32 causes the hammer to rapidly rotate, striking the piezo-electric element 26 and generating a spark. At the time of ignition the gas flow is at a maximum but the flow to outlet 12 may be controlled as previously mentioned. Due to a lost-motion device comprising a lug 30, which is connected to the spindle and engages abutment surfaces 31a and 31b provided on the cam member this control can be effected without the hammer returning to the position shown in Fig. 1 until the spindle is in the "off", or substantially "off" position. The detent member is preferably metal and in an alternative embodiment only one outlet is provided.
