Title: Method of forming a multiple electrode arrangement
IPC: B41J2/425
Filed: 1974-10-04
Abstract: 1457649 Etching ROBERT BOSCH GmbH 4 Oct 1974 [5 Oct 1973] 43078/74 Heading B6J [Also in Divisions G1 and H1] A metallic sheet to be etched into multiple individual electrodes (Fig. 1, not shown) is coated on each surface with photoresist varnish on which surfaces are placed photomasks defining the electrodes to be produced; which may, e.g. form a multiple electrode comb for recording on metallized paper; by exposing the photoresist varnish through the masks, removing the unexposed varnish, and etching out to leave intact the metal regions protected by exposed varnish. The metal may be spring steel, chrome nickel steel, or beryllium copper. A negative upper photomask 13 (Fig. 2a) comprises four transverse recesses 15 and plural other recesses 16, 17 whereby regions of photovarnish are exposed and during subsequent etching define connecting bars 18, 19, 20 in the metal sheet (Figs. 4, 8). The recesses may be defined as translucent sections for a glass or plastic sheet. A negative lower photomask 14 (Fig. 2b) has similar layout but without recesses defining connecting bars, which may thus be etched down from one side to a thickness of half the metal sheet thickness (Fig. 3, not shown). The masks are held in register along the edges 21 and define an envelope for the metal sheet to be etched. Thereafter the etched sheet is glued to a support 23 of, e.g. epoxy based GRP and comprises in cross-section (Fig. 4) a multiplicity of electrodes 22 connected by a connecting bar 18. A further photoresist varnish layer is applied to the exposed side of the electrode assembly and exposed through a further negative photomask (Fig. 5) so that the electrodes 22 are protected and the exposed connecting bars are etched out so as to produce an array of separated multiple electrodes 22 adherent to the support (Fig. 6, not shown) whose plan layout (Fig. 7) comprises plural mutually insulated contact segments 26 of the respective electrodes. The connecting bars may alternatively be removed mechanically from the arrangement produced by the first etch. An alternative form of comb electrode 27 (Fig. 8) has connecting bars 19 formed between the individual contact segments 26 and between printed circuit conductors 28; aligned contact bores 30 being provided together with a further connecting bar 32 between the last segment and the adjoining printed circuit conductor 28 and a bridge 33 across the tips of electrodes 22. After adhesion to a support bars 19, 20, 32 are etched out, together with bridge 32. The electrode tips may be reinforced by diffusion soldering. A multiple electrode arrangement (Fig. 9, not shown) may have bridges connecting the electrode tips and contacts respectively with oblique connecting bars joining the contacts with the appropriate bridge; the bars remaining after removal of the bridges. An electrode arrangement and a printed circuit may be produced simultaneously or separately by etching and adhesively attached to a substrate, after etching out of the connecting bars and holding bridges (Fig. 10, not shown).

Each pair of motors 134, 134<SP>1</SP> is mounted on a plate (120), Fig. 4 (not shown), which forms one of a system of plates (120), (122), (126) and (128), the outer plates (120), (122) being resiliently mounted within apertures in grids 114, Fig. 1, which form opposite side walls of the hopper 102. The gases released by vibration of the material escape through a vent 112. The nip between rollers 202, 204 may be varied by rotation of a hand wheel 226 screw-threaded into a guide block 224. A conveyer belt 244 carries away individually moulded articles, when cavited rollers are employed, or flakes formed by breakage of a sheet against the belt when smooth rollers are employed. In a second embodiment, Fig. 5 (not shown), each pair of motors 134, 134<SP>1</SP> is resiliently mounted in an aperture of a side wall of the hopper and the systems of plates are supported by wires (152) suspended from a cross-bar (154).

Filed: 1972-09-19
Abstract: 1400054 Protective arrangements UNISEARCH Ltd 19 Sept 1972 [24 Sept 1971] 43350/72 Heading H2K  A protective arrangement for a transformer comprises means CT1, CT2, B1 to measure the current in the transformer windings and to obtain the differential current, means B2 to estimate from the currents the voltage of one transformer winding, means VT to measure the actual voltage of that winding, means B3 to determine a difference voltage between the estimated and actual voltages, means B5, B4 to provide output signals when the differential current and the difference voltage exceed respective reference values, and means B6 to provide a signal for disconnecting the transformer when both out put signals exist simultaneously. The means B1 ... B5 may each include one or more integrated circuit operational amplifiers and the means B6 may be a NOR gate which is connected to a device B7 having a pulse transformer to provide a gating signal to a thyristor in circuit with a trip coil Co, Figs. 2 to 8 (not shown). The reference values may be obtained from a battery Ba1 and potentiometers D1, D2 as shown. Alternatively a variable reference value for the means B4 may be obtained from the differential current, Fig. 9 (not shown). In protecting a three phase transformer having a delta winding, three current transformers are connected to measure the line currents and a fourth current transformer is connected to measure one of the phase currents. The other two phase currents are determined by summation of the appropriate currents, Figs. 11 and 12 (not shown). In an alternative arrangement the currents and voltage of the transformer may be sampled, and after conversion in digital form, be used in conjunction with a digital computer to disconnect the transformer when the differential current and voltage difference simultaneously exceed their respective reference values. In this case the samples converted into digital form are stored in the memory of a computer which has been programmed to perform the processes performed by means B 1 -B 6 .

Filed: 1959-12-24
Abstract: A crystalline linear polymer of an aliphatic mono-olefin in comminuted form is contacted with 2.5 to 10% of styrene monomer and the imbibed styrene is polymerized in situ at a temperature insufficient to coalesce the particles, said particles being subsequently shaped and thereafter treated with an halogenoalkylating agent and then a tertiary amine whereby quaternary ammonium salt groups are nuclearly substituted in the aromatic constituent to an appreciable distance inward from the surface, optionally throughout the whole thickness of the shaped article.  Specified monoolefins are ethylene and propylene and the after treatment exemplified is with chloromethyl ether and trimethylamine.  Polymerization is preferably effected with a free radical catalyst, e.g. benzoyl peroxide.  The products which may be in the form of film, filament, fibre, sheet or strip, have increased receptivity for dyes (e.g. acid wool dyes) and do not accumulate static charges.
