Title: Improvements in or relating to electric circuits
IPC: H03K19/16
Filed: 1954-10-13
Abstract: 762,823. Non-contact-making relays. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 13, 1954 [Oct. 15, 1953], No. 29499/54. Class 40 (4). An AND or OR gate comprises a number of saturable cores each having two windings, one winding being connected to a common alternating or pulse source while the other is associated with an individual input. As shown in Fig. 1, an AND gate comprises saturable cores 1, 2 and 3 having input windings a, band c connected to sources I, II and III respectively, and output windings A, B and C arranged in series with an impedance R and a low-impedance alternating voltage or pulse source G. In this arrangement an effective output voltage u is produced across R only when all the cores are saturated simultaneously by currents in their respective input windings. When the inputs comprise pulses they are synchronized with the pulse source G. In a modification, Fig. 4, the impedance R is omitted and an inverse AND output u of zero value is obtained across the series-connected windings A, B, C under the same conditions, a current pulse source GC of high internal impedance being employed in this case. If the windings A, B and C are connected in parallel the arrangement constitutes an OR gate, Fig. 3, in which a zero output across impedance R is obtained only when inputs from I, II and III are simultaneously zero. An inverse OR output is obtained when the circuit comprising the windings A, B and C is arranged as in Fig. 6. The cores may alternatively constitute saturable transformers, the windings A, B and C being coupled with a separate output circuit. This modification as applied to the inverse AND arrangement shown in Fig. 4 is illustrated in Fig. 5, the output u being obtained across series-connected secondary windings A', B<SP>1</SP> and C<SP>1</SP>. Series or parallel connections of the windings A, B, C and A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP> may be used, Figs. 7 to 9 (not shown). The transformer arrangements may be further modified by the use of three-legged cores 4, 5, 6, Fig. 10, and divided windings A, B, C which are then magnetically decoupled from the input windings a, b, c. The arrangement illustrated constitutes an AND gate. To ensure that an effective zero output is obtained under the appropriate conditions, Fig. 11, the combined voltage induced in windings A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP> when all the cores are saturated may be opposed by an equal and opposite voltage injected by a transformer 10.

Abstract: 505,089. Moulding plastic materials. BRATRING, K., and INTERNATIONAL CONTAINERS, Ltd. Nov. 1, 1937, No. 29873. Convention date, Nov. 30, 1936. [Class 87 (ii)] [Also in Groups IV and XVII] A waterproof hollow body is obtained by applying to a core a layer of a non-aqueous solution of a cellulose derivative, drying this layer, then applying a second layer consisting of rubber or the like or a synthetic resin, drying this layer, applying a non-aqueous solution of a cellulose derivative and drying this third layer. The cellulose derivative may be cellulose acetate, or nitrate, or other ester or ether. Instead of caoutchouc there may be used guttapercha, or balata. If a synthetic resin is used, it may be a glycerol-phthalic anhydride, or polyvinyl ester resin. Plasticizers may be present in any or all of the layers. A core may be immersed in a solution of cellulose acetate in acetone containing triphenyl phosphate or dibutyl phthalate, then in a solution of caoutchouc in benzol with an addition of a phenolaldehyde resin, and then in a solution of cellulose acetate. A solvent, e.g. methylene chloride mixed with ethyl alcohol or cyclohexanone, which is common to both the cellulose derivative layers and to the rubber or synthetic resin layer may be used. Butyl stearate may be used as plasticizer for the rubber layer.If the three-layer material is too thin, additional layers of rubber and cellulose derivative may be applied, the outer layer being of a cellulose derivative. During immersion in the rubber layer the uppermost part of the first layer may be left uncovered. When the third layer is applied, a firm adhesion between the inner and outer cellulose derivative layers is obtained. The process is applicable to the production of tubes or containers for liquids or plastic materials. The Specification as open to inspection under Sect. 91 comprises also the production of waterproof films. This subject-matter does not appear in the Specification as accepted.

[Also in Division H4] A temperature sensor comprises a crystal of terbium iron garnet (TbIG), which exhibits a temperature dependent Faraday effect, and means for measuring the rotation of the plane of polarization of light due to the device. Measuring temperature. Plane polarized 1À15Á radiation from a He-Ne laser passes twice through a TbIG crystal 1 by reflection off a layer 2 and passes through an analyzer 8 to an infrared detector 9. A polepiece 3 provides sufficient magnetic field to saturate crystal 1 in the direction H 2 . The plane of polarization of the emergent beam 7 may be measured by adjusting the analyzer 8 for minimum transmission. Alternatively the analyzer may be fixed and the polarization of beam 7 allowed to vary between 40 degrees and 50 degrees of the maximum transmission position. Compensation for light source variations may be by a reference detector receiving light from the laser and controlling the drive to keep the intensity constant. Alternatively an A. C. polarization modulation of Œ 1 degree may be imposed on beam 4 by a modulator 6. The A. C. component of the detector signal is the separated out and the laser controlled to keep it constant. Two state operation TbIG exhibits a sudden change of sign of Faraday effect at a "compensation temperature". The sign of the effect may be detected and used as error signal for a two-step automatic temperature controller. The compensation temperature may be increased by incorporating Ga or Al in place of some of the Fe in the TbIg or reduced by In or Sc.
