The molecular weight of the epoxy resin is 350-400 and its viscosity is 120 poises at 25 DEG  C.  The mixture is heated at 170 DEG  C. for 15 minutes in contact with the electrotype. In a second example, the mixture comprises  60 gms. polyvinyl chloride, 10 gms. dioctyl phthalate, 7 gms. dibutyl phthalate, 23 gms. epoxy resin, 3 gms. ethylene-tetramine,  and in a further example two mixtures are prepared, one containing  100 gms. polyvinyl chloride, 31 gms. decyl phthalate, 28 gms. "Epon 820,"  3.2 gms. of a surface-active product called "Homoflex 21," and the other containing 100 gms. polyvinyl chloride, 45 gms. decyl phthalate, 7.56 gms. of a mixture of 4,41-methylenedianiline and metaphenylene-diamine, and 3 gms.  "Homoflex 21."  The two pastes are mixed together and injected into a mould containing the electrotype.  Amines such as tridimethylaminomethylphenol, diamino - di -phenylsulphone and 4,41-methylene-dianiline may be used alone or with metaphenylenediamine as hardeners for the epoxy resin.ALSO:A copper electrotype printing plate is provided with a backing comprising a polymer or copolymer of vinyl chloride and a thermosetting resin.  In one example 100 gms. of polyvinyl chloride, 30 gms. of a plasticizer, decylphthalate, 26 gms, of an epoxy resin, and 7 gms. of a hardener 4,41-methylene-dianiline are mixed to form a paste which is spread with a scraper in a layer 3,5 mm. thick on a copper electrotype.  The paste is hardened by heating at 170  DEG C. for 15 minutes and is then worked to obtain a thickness of 3 mm.  The quantities of epoxy resin or of a derivative thereof added to the plasticized polymer or copolymer of vinyl chloride are preferably between 8% and 30% by weight relative to the weight of said polymer or copolymer.  In a further example two mixtures are used, one consisting of a portion of the vinyl resin, a portion of the plasticizer, and the whole of the thermosetting resin, and the other consisting of the rest of the vinyl resin, the rest of the plasticizer, and the whole of the hardener, the two mixtures being mixed together to form a paste which is then injected into moulds containing copper electrotypes.

[Class 40 (v)] In a negative feedback amplifier the phase and gain in the feedback path are so modified that instability is prevented whilst leaving the gain substantially unaffected in the operating range. Fig. 1 shows an amplifier of the kind described in Specification 472,256 covering a range of 12 ... 60 kc., and in Fig. 3 the curve Á shows the phase shift, f1, f2 being the limits of the operating range without correction. The phase shift may be corrected at the ends of the range by inductance L1 shunted by resistance R4 and condenser C2 shunted by resistance R2 to obtain a curve #, Fig. 3. A bridge type of feedback for both input and output may be used, Fig. 6 (not shown), while Figs. 8, 8a show modified phase correcting networks which may be used in the feedback circuit when a phase shift of more than 90‹ is required to give a curve #2, Fig. 3. A band elimination filter may be incorporated in the feedback path and a plurality of feedback paths may be used which may include the input and output transformer. With two feedback paths, the corrective networks may be divided so that one path corrects the upper, and the other path the lower end of the frequency scale.

Title: Improvements in or relating to magnetic devices
IPC: G11C11/06
Filed: 1958-06-24
Abstract: 884,431. Magnetic storage devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 24, 1958 [June 24, 1957], No. 20217/58. Class 38 (2). [Also in Group XXXIX] A magnetic storage device comprises a crystal K (Fig. 1) of ferroxplana material (such as Ba 2  M e F 12 O 22  where Me comprises one or more divalent metals including cobalt) having three directions of easy magnetization linked with windings 1, 2 and 3 current in which can produce remanent states of magnetization in directions I, II and III respectively. The crystal K may be disc shaped and may be enclosed within a ferrite ring S or provided with a ring 15 (Fig. 5) of soft magnetic material having slots 16, 17, 18 for windings 19, 20, 21. In non- destructive reading-out of the direction of remanent magnetization application of a weak pulse to winding 1 produces equal low pulses in windings 2 and 3 if the direction of remanent magnetization is I, a higher pulse in 3 than in 2 if the direction is II and a higher pulse in 2 than in 3 if the direction is III. Windings 2 and 3 can be replaced by a single winding arranged at right angles to winding 1. Reading out can be done by a strong pulse so that the magnetization assumes a direction determined by the winding carrying the pulse. The device may be used as an adding element by arranging for the direction of remanent magnetization to be reversed only by pulses in two windings jointly. The device can be used for a coincidence circuit, pulses in windings 2 and 3 producing a greater pulse in winding 1 when they coincide. Two such devices 7 and 8 may be used in a pulsedifferentiating circuit as shown in Fig. 4 in which 10 is the source of the pulses to be tested and 9 is a clock-pulse generator. While pulses in 9 and 10 coincide the magnetization direction in device 7 will remain at II and the magnetization direction in device 8 will remain at - III<SP>1</SP>, no pulse being produced in output winding I<SP>1</SP>. If a pulse is then received only from 9 the direction of magnetization of 7 is shifted to - III. The next coincidence of pulses then produces a pulse in winding 2 which results in the production of a pulse in output winding 1<SP>1</SP>. On subsequent coincidence of pulses magnetization of device 8 returns to - III<SP>1</SP> and an opposite pulse is produced in output winding 1<SP>1</SP>.

Abstract: 1,056,169. Electronic side-man. SEEBURG CORPORATION. May 15, 1964 [Sept. 23, 1963], No.20296/64. Heading G5J. The Specification describes an electronic side-man consisting of a number of electronic sound sources 26, 27, 28, which simulate e.g. drums, blocks, and cymbals respectively and which are energized one or more at a time in a predetermined sequence to produce various rhythms. A rotating contact 25 driven by a synchronous motor itself controlled by a variable-frequency oscillator connects a pulsing voltage V to each of terminals 1, 2, 3 in turn. Some of these terminals are connected to one of the sound sources, some to more than one but the invention consists in the provision of diodes 138-145 which enables a number of sources to be pulsed from a single terminal while isolating the sources from each other. Thus the rotating contact will, in position 1, pulse all of sources 26, 27, and 28 through diodes 138, 141 and 143, and 141 only, respectively; in position 2 source 26 only is pulsed and in position 3 sources 26 and 28 are pulsed, diode 138 acting to prevent transmission of the pulse on contact 3 to source 27. In order to increase the versatility of the arrangement each of the sound sources is connected to one of the wafers of a manual selector switch 31 the contacts of which are ganged together to give various combinations of instruments. Silicon diodes are used. In further arrangements (Fig. 5, not shown) separate voltage sources are used for each sound source, the rotating contact acting to complete an earth path.
